Abstract:
1. A code division multiple access (CDMA) subscriber unit comprising: a circuitry for receiving a shared channel, wherein the shared channel carries data in distinct time intervals, each time interval of the shared channel carries data for one specific CDMA subscriber unit, at least a portion of the data for the one specific CDMA subscriber unit is modulo-2 combined with a CDMA subscriber unit specific cover sequence associated with that one specific CDMA subscriber unit; a circuitry for receiving information for use in determining which CDMA subscriber unit specific cover sequence is associated with the CDMA subscriber unit, wherein the CDMA subscriber unit specific cover sequence determining information is received during a configuration process; a circuitry for discarding data of one of the time intervals of the received shared channel if an error is detected based on an error detection code; wherein the CDMA subscriber unit does not receive an assignment of the distinct time interval of the shared channels; and a circuitry for recovering data of one of the time intervals if an error is not detected based on the error detection code; wherein the recovered data includes a field including a first portion of a packet, a sequence number field and a length field; wherein a second portion of the packet is recovered by the circuitry configured to recover data in a different one of the time intervals and combine the first portion with at least the second portion to recover the packet.
