Method and apparatus for manipulating cell selections and transitions to and from an improved Cell_FACH state.
FIELD OF THE INVENTION
This application relates to wireless communications.
BACKGROUND
User equipment (UEs) on a universal telecommunications radio access network (UTRAN) are typically one of two modes: Idle or Connected. Based on the activity and mobility of UE in connected mode, UTRAN can direct the UE to transition between a number of substates, such as cell pager channel (Cell_PCH), UTRAN registration area pager channel (URA_PCH), channel frontal cell access (Cell_FACH) and Cell_DCH. This is typically accomplished through a network-based reconfiguration procedure or as a result of a cell update procedure. The latter is initiated by the UE to inform the network of its current location. The Cell_DCH state is characterized by dedicated channels on the upper link and the lower link. On the UE side, this corresponds to continuous transmission and reception and can require a lot of power from the user. The Cell_FACH status does not use dedicated channels and therefore allows better energy consumption, at the expense of higher link and lower link yield.
Recent work by the standardization bodies has identified the possibility of using High Speed Lower Link Packet Access (HSDPA) in Cell_FACH and Cell / URA_PACH. HSDPA is a feature that was introduced in Version 5 of the Third Generation Partnership Project (3GPP) specifications to operate in Cell_DCH. HSDPA tries to make better use of the shared lower link capacity using concepts such as Adaptive Coding and Modulation (AMC), retransmissions using a Hybrid ARQ (HARQ) scheme and Node B programming, all operating at a very high speed. Packet data units (PDUs) are combined by HARQ and then stored in a reordering queue to handle possible out of order reception. The lower link transmissions are addressed to a UE through an HS-DSCH Radio Network Identifier (H-RNTI).
It is considered that if the UE supports HSDPA in Version 7, it also supports HSDPA in CELL_FACH and CELL / URA_PCH. HS-DSCH reception in CELL_FACH can be configured without HS-DSCH reception in CELL_PCH and URA_PCH. High-speed lower link shared channel reception (HS-DSCH) in CELL_PCH and URA_PCH without the support of HS-DSCH reception in CELL_FACH is not supported. UE support for these features is signaled to the network. It should be understood that the achievements presented can be extended to cases where HSDPA support in
2/13
CELL_FACH and / or CELL_PCH / URA_PCH can be signaled individually to the network.
On the other hand, the network signals its support for improved CELL_FACH through the System Information Block (SIB5 / 5bis). Two new information elements (LE) were introduced;
- "common HS-DSCH system information": indicates that HSDPA reception is sustained to state CELL_FACH; and
- “HS-DSCH pager system information”: indicates that HSDPA reception is supported for CELL / URA_PCH status.
To indicate whether HS-DSCH reception is in progress at CELL_FACH, two new Boolean variables have been added:
- RECEIPT OF HS DSCH STATE CELL FACH: if TRUE, it indicates that the reception of HS-DSCH in CELL_FACH is in progress; and
- CCCH HS DSCH RECEPTION ALLOWED: if TRUE, it indicates that HS-DSCH reception is allowed for CCCH. This variable is set to TRUE when the UE is using a common H-RNTI to receive HSDPA traffic and is set to FALSE when the UE is not.
A UE is assigned a common H-RNTI to receive traffic when it has not been assigned a dedicated H-RNTI. These three situations are as follows:
1. The UE sends a REQUEST Radio Resource Control (RRC) CONNECTION message (and the UE is awaiting a CONFIGURE RRC CONNECTION connection from the network).
2. The UE sends an UPDATE CELL message and is waiting for a CONFIRM CELL UPDATE response from the network.
3. UE sends an UPDATE IVR message and is waiting for a response
CONFIRM URA UPDATE from the network.
No new variables have been proposed to indicate receipt of CELL / URA_PCH HS-DSCH. When in CELL / URA_PCH and if “HS-DSCH pager system information” is transmitted, the UE configures the reception of HSDPA. In some cases, a UE will no longer be able to proceed with the reception of PDUs at high speed (such as the result of hard delivery, new cell selection, radio link failure and the like). In these cases, the MAC must be restarted. The restart procedure allows the UE to forward all PDUs in the reordering queues to upper layers and reset all state variables at high speed.
In 3GPP Version 6, HSDPA was only supported at CELL_DCH. As a result, MAC restarts were performed (such as a restart of
3/13
MAC-HS) under the following conditions: the UE experienced a radio link failure, the UE experienced an unrecoverable RLC error, or the UE was ordered to transition to a state where HSDPA was not supported (all states except CELL_DCH).
In Version 7, as currently defined, a UE can be asked to perform a MAC reset in the following states: CELL_DCH, CELL_FACH, CELL / URA_PCH. In addition to the conditions specified above (ie, which apply to a UE in CELL_DCH), the UE is requested to perform a MAC reset after ALL the new cell selections. Currently, this is only done when the WTRU with a dedicated H-RNTI performs a new cell selection. There are a number of scenarios in which this restart is not performed, which results in possible reordering errors.
Transitions to / from OCIOSO were also impacted by the introduction of improved CELL_FACH. If a UE Version 7 supports HSDPA reception in CELL_FACH state, that UE also supports limited HSDPA reception while in Idle mode; particularly after the UE issues a RRC CONNECTION REQUEST and when it is waiting for a network RRC CONNECTION CONFIGURATION message. Three issues were identified:
1. If the UE has started receiving HSDPA while idle (after issuing a RRC CONNECTION CONFIGURATION message), all new cell selections should result in a MAC reset.
2. If an RRC connection procedure is aborted, the UE must clear all of its HSDPA resources.
3. While in Idle mode, a UE can reselect the cell from a cell that supports enhanced CELL FACH to one that does not and vice versa. If the UE has initiated a RRC connection procedure, two issues may need to be addressed. First, for a transition from Version 6 to Version 7, the UE is requested to configure the HSDPA resources so that it can receive the message CONFIGURE RRC CONNECTION on the HS-DSCH. Second, for a transition from Version 7 to Version 6, the UE must release all HSDPA resources, as traffic on the HS-DSCH is not expected.
Another new feature of CELL_FACH Enhanced is that the UE will be able to receive dedicated control messages while in CELL_PCH (on the DCCH). Consequently, a UE can be asked to perform a reconfiguration (such as radio carrier, transport channel, physical channel). Reconfiguration messages can also result in a change of state.
In order to allow for the appropriate configuration of
4/13
HSDPA, the UE should properly manage the setting or clearing of the CCCH HS DSCH ALLOWED variable PERMITTED to ensure that it is only set to TRUE when the UE is using the common H-RNTI while in an enhanced Cell_FACH state. It must be set to FALSE in all other cases. Finally, the new cell selections that occur during the ongoing cell update or IVR update procedures should behave similarly to new cell selections when these procedures are not in progress.
It would therefore be beneficial to provide a method and apparatus for handling new cell selections and transitions to and from an improved CELL_FACH state.
SUMMARY OF THE INVENTION
A method and apparatus for manipulating new cell selections, transitions and failures of Cell_DCH radio links are described. The method includes running a new cell selection. A means access control (MAC) reset is performed.

When indicated below, the terminology “base station” includes, but is not limited to, a Node B, location controller, access point (AP) or any other type of interface device capable of operating in a wireless environment.
When indicated below, the terminology “Version 7 (V7)” includes but is not limited to a WTRU or Node B that supports HS-DSCH in CELL_FACH and / or CELL / URA_PCH and “Version 6 (V6)” includes, but without limiting itself to a WTRU or Node B
5/13 that does not support HS-DSCH in CELL_FACH and / or CELL / URA_PCH.
HS-DSCH in CELL_FACH also includes receiving HS-DSCH in idle mode for receiving RRC connection procedures.
When indicated below, the terminology “enhanced CELL_FACH state” includes, but is not limited to, a WTRU using HSDPA resources in a state other than CELL_DCH.
Figure 1 shows an example of a wireless communication system 100 that includes a series of WTRUs 110, a Node B 120 and a radio network controller (RNC) 130. As shown in Figure 1, WTRUs 110 are in communication with Node B 120, which is in communication with RNC 130. It should be noted that, although an example of configuring WTRUs 110, Node B 120 and RNC 130 is shown in Figure 1, any combination of wired and wireless devices can be included in the wireless communication system 100.
Figure 2 is an example of functional block diagram 200 of a WTRU 100 and Node B 120 of the wireless communication system 100 of Figure 1. As shown in Figure 2, WTRU 110 is in communication with Node B 120. Node B 120 is configured to handle new cell selections and transitions to and from an improved Cell_FACH state.
In addition to the components that can be found in a typical WTRU, WTRU 110 includes a processor 115, a receiver 116, a transmitter 117 and an antenna 118. Receiver 116 and transmitter 117 are in communication with processor 115. A antenna 118 is in communication with receiver 116 and transmitter 117 to facilitate wireless data transmission and reception. Processor 115 of the WTRU 110 is configured to handle new cell selections and transitions to and from an improved Cell_FACH state.
In addition to the components that can be found on a typical Node B, Node B 120 includes a processor 125, a receiver 126, a transmitter 127 and an antenna 128. Receiver 126 and transmitter 127 are in communication with processor 125 Antenna 128 is in communication with receiver 126 and transmitter 127 to facilitate wireless data transmission and reception.
Figure 3 is a flow chart of a method 300 of manipulating new cell selections from an enhanced CELL_FACH state. Although the details of method 300 are described in more detail below, in general, a WTRU 110 performs a new cell selection (step 310). When executing the new cell selection, a reset of access control to means (MAC) -ehs (step 320), due to the fact that the source of the HS-DSCH may have been changed. Depending on the cell selected again, the WTRU 110 can clear HSDPA resources and suspend HS-DSCH reception procedures.

In one example, the restart of MAC-hs / ehs is performed when a new cell selection occurs while the WTRU 110 is waiting for a CONFIRM CELL UPDATE message. The restart can be performed in all cases by means of a new cell selection (that is, even when the WTRU does not have a dedicated H-RNTI) or only when the WTRU has HSDPA reception in progress (that is, when the WTRU is receiving HS -DSCH before the new cell selection).
If the cell update / IVR update timer expires or a new selection occurs for another UTRA cell before the end of the cell update or IVR update procedure, for example, the WTRU 110 can detect “in service area” if not has entered idle mode. In this case, if the cell update procedure or IVR update counter is less than or equal to a maximum number of retransmissions of the cell update / IVR update message, the WTRU 110 can perform a new cell selection.
For frequency division duplex (FDD), for example, if the WTRU 110 supports HS-DSCH reception and the information element (IE) “HS-DSCH common system information is included in SIB5 or SIBõbis, the WTRU 110 can restart the MAC-ehs entity.
Alternatively, WTRU 110 can, after performing a cell selection, restart the MAC-ehs entity after a CELL_DCH radio link failure. Since the WTRU 110 may be using a standard H-RNTI, instead of a dedicated H-RNTI, a restart can allow reception of a new MAC stream (such as for CCCH and SRB1).
The WTRU 110 can initiate a cell update procedure, for example, as a result of a radio link failure while in CELL_DCH. For FDD, if the WTRU 110 supports HS-DSCH reception and the information element (IE) “common HS-DSCH system information” is included in SIB5 or SIB5bis, the WTRU 110 can restart the MAC-ehs entity .
Alternatively, after performing a new cell selection without a dedicated H-RNTI, the WTRU 110 can restart the MAC-ehs entity.
The WTRU 110 can initiate, for example, an IVR or cell update procedure. If the WTRU 110 made a new cell selection, for FDD, if the WTRU 110 supports the reception of HS-DSCH and the information element (IE) “common HS-DSCH system information” is included in SIB5 or SIB5bis, the WTRU 110 can reset the MAC-ehs entity.
The WTRU 110 is allowed to use HSDSCH reception in Idle mode (such as after the transmission of an RRC CONNECTION REQUEST). When the WTRU 110 transmits a REQUEST FOR
7/13
RRC CONNECTION, it monitors the lower link transmissions to determine the RNC response. During this period, the WTRU 110 can make new cell selections.
Depending on the cell selected again, the WTRU 110 can transition from a cell that supports HSDPA reception in CELL_FACH and CELL / URA_PCH to one that no longer supports HSDSCH reception. WTRU 110 can clear or release HSDPA resources and suspend HS-DSCH receipt procedures.
If the WTRU 110 has transmitted a RRC CONNECTION REQUEST and has not yet received a RRC CONNECTION CONFIGURATION message with the value of the IE “initial EU identity” equal to the value of the INITIAL EU IDENTITY variable and if a new cell selection occurs or expiration of the RRC CONNECTION REQUIREMENT timers (currently referred to in the T300 or T318 standard), WTRU 110 can verify that the RRC CONNECTION procedure counter (currently referred to in the V300 standard) is less than or equal to the maximum number of retransmissions of the RRC CONNECTION REQUEST message (currently referred to in the N300 standard) and, if a new selection has occurred cellular to FDD, if WTRU 110 supports HS-DSCH reception and if IE “HS-DSCH common system information” is not included in SIB5 or SIBõbis, the WTRU 110 can release HSDPA resources by suspending the HS_SCCH and HS-DSCH reception procedures. In addition, WTRU 110 can clear the H_RNTI variable and remove any stored H-RNTI. In addition to restarting the MAC-ehs entity, the WTRU 110 can also free all HARQ resources.
Alternatively, WTRU 110 may decide to perform the above only when HSDPA resources are being used before the new cell selection.
In addition, the actions of the WTRU 110 can be triggered using an existing HS DSCH RECEPTION variable or a new HS DSCH RECEPTION variable can be defined as a mark to indicate the use of HSDPA resources, in order to trigger a release of resources .
Depending on the cell selected again, the WTRU 110 can transition over cells that support HSDPA reception in CELL_FACH and CELL / URA_PCH. The WTRU can perform a MAC-ehs reset.
If WTRU 110 has transmitted a RRC CONNECTION REQUEST and has not yet received a CONFIGURE RRC CONNECTION message with the value of the IE “Initial EU Identity” equal to the value of the INITIAL EU IDENTITY variable and if a new cell selection occurs or end of timers RRC CONNECTION REQUEST (T300 or T318), WTRU 110
8/13 can verify that the RRC CONNECTION (V300) procedure counter is less than or equal to the maximum number of retransmissions of the message REQUEST RRC CONNECTION (N300) and, if a new cell selection has occurred, for FDD, if the WTRU 110 sustain HS-DSCH reception, if IE: “common HS-DSCH system information” is included in SIB5 or SIBõbis and if the variable “CCCH HS DSCH ALLOWED PERMITTED” is set to TRUE, WTRU 110 can restart the MAC-ehs entity.
Depending on the cell selected again, the WTRU 110 can transition from a cell that does not support HSDPA reception in CELL_FACH and CELL / URA_PCH to one that supports HS-DSCH reception. In this case, the WTRU 110 can be asked to configure the HS-DSCH (such as HARQ resources, common H-RNTI, MAC flow for CCCH traffic and the like).
In this situation, a number of scenarios can be used. If the WTRU 110 has transmitted a RRC CONNECTION REQUEST, for example, and has not yet received a CONFIGURE RRC CONNECTION message with the value of the IE “Initial EU Identity” equal to the value of the INITIAL EU IDENTITY variable and, if there is a new cell selection or the end of timers RRC CONNECTION REQUEST (T300 or T318), the WTRU 110 can verify that the RRC CONNECTION (V300) procedure counter is less than or equal to the maximum number of retransmissions of the message REQUEST RRC CONNECTION (N300) and, if a new cell selection has occurred, for FDD, if the WTRU 110 sustain HS-DSCH reception, if IE: “Common HS-DSCH system information is included in SIB5 or SIBõbis and if the variable“ CCCH HS DSCH RECEIVER ALLOWED ”is set to FALSE, WTRU 110 can define the“ CCCH HS DSCH ALLOWED ALLOWED ”variable as TRUE and start receiving HS-DSCH.
Alternatively, a WTRU 110 in Idle mode can set the CCCH tag to TRUE in an R6 cell. In order to ensure that HS DSCH RECEIVING OF ALLOWED CCCH is TRUE in an R6 cell, the variable must be set to TRUE whenever system information is read in an R6 cell or whenever WTRU 110 is in an R6 cell and transition to idle mode from connected mode. This can be achieved by changing the actions when entering idle mode from connected mode.
As another alternative, whenever a WTRU 110 in Idle mode with an RRC connection procedure in progress makes a new cell selection, the WTRU sets the CCCH brand to TRUE and then performs the actions related to that variable. The WTRU 110 can send, for example, a REQUEST RRC CONNECTION message and wait for a CONFIGURE RRC CONNECTION message. If there is a new cell selection and the transition is from a cell
9/13
R7 to R7, the MAC-ehs entity is only restarted. If the transmission is from a cell R6 to R7, the variable RECEPTION OF HS DSCH OF CCCH PERMITTED is defined as “true” and the WTRU begins to receive the HS-DSCH. If the transition is from an R7 to R6 cell, the HS_SCCH reception procedures are suspended, the HS-DSCH reception procedures are suspended, the MAC-ehs entity is restarted, HARQ resources are released and storage “HARQ information” is cleared.
The CCCH HS DSCH ALLOWED PERMITTED variable is used as a mark to indicate that the WTRU 110 is using a common H-RNTI. This variable must be defined as “FALSE” when WTRU 110 is not using its common H-RNTI. This can ensure that the evaluation of the RECEIPT OF HS_DSCH STATE OF CELL_FACH variable correctly clears resources only when a dedicated H-RNTI is assigned to WTRU 110. It is typically possible to receive on the common H-RNTI when the WTRU 110 has made a new cell selection and is waiting for the CONFIRM CELL UPDATE message or when the WTRU 110 has made a new URA selection and is waiting for the CONFIRM URA UPDATE message, or when the WTRU 110 has started an RRC configuration and is waiting for the message CONFIGURE RRC CONNECTION.
After receiving a CONFIGURE RRC CONNECTION message that will send the WTRU 110 in the CELL_DCH state, the WTRU 110 defines the HS DSCH RECEIVING CCCH ALLOWED variable as "FALSE".
WTRU 110 may terminate activities associated with CELL_PCH. The WTRU 110 should suspend, for example, the periodic cell update timer. If the network requests a transition to CELL_FACH or if a new configuration is provided for CELL_PCH, WTRU 110 must perform actions similar to those during the transition to CELL_FACH.
If the IE “frequency information” is included in the received reconfiguration message, for example, the WTRU 110 can select an appropriate cell on the frequency provided. If the IE “frequency information” is not included in the received reconfiguration message, the WTRU 110 can prohibit the transmission of periodic status on the RLC and can start the timer currently named in the T305 standard. If the “new C-RNTI” IE is not included in the reconfiguration message, the WTRU 110 can clear the variables C_RNTI, H_RNTI and any stored HARQ information and can also restart the MAC-ehs entity. The WTRU 110 can start monitoring pager occasions on the selected PICH and, if the IE “DRX UTRAN cycle length coefficient” is included, it can use this value to determine pager occasions.
