Wireless communications network incorporating voice over ip using shared supplemental spreading codes

Embodiments provided include a method for transmitting a packet to a receiver over primary and supplemental channels in a wireless communication network. Indications of a primary code and a set of N supplemental codes assigned to the receiver are communicated over a control channel. When it is determined that a packet should be transmitted over a supplemental channel, a first portion of the packet and a supplemental channel indicator are transmitted over a same single packet transmission time interval on the primary channel and a second portion of the packet is transmitted over the same single packet transmission time interval on the supplemental channel corresponding to the supplemental channel indicator. The supplemental channel uses an assigned specific supplemental code belonging to the set of N supplemental codes assigned to the receiver. When the packet should not be transmitted over a supplemental channel, the packet is transmitted over the primary channel.
