Abstract: A method, apparatus, and radio receiver system for canceling multi-user interference in a single-carrier radio communication system. A front-end receiver such as a RAKE receiver receives a radio signal formatted in a sequence of frames, and outputs a plurality of user signals. A processing selector selects on a frame-by-frame basis, either a first signal processing chain that serially decodes and removes the interference contributions of the user signals, or a second signal processing chain that simultaneously decodes and removes the interference contributions of the user signals in parallel. The processing selector may select the first signal processing chain when the number of user signals is greater than or equal to a threshold value, and may select the second signal processing chain when the number of user signals is less than the threshold value.

Abstract: A UE of a spread spectrum wireless telecommunications system includes a network interface unit which receives multiple path energies of a wireless signal. The UE includes a rake receiver in communication with the network interface unit. The UE includes an equalizer in communication with the network interface unit, either the rake receiver or the equalizer processes the signal based on a predetermined criteria. A method of maintaining performance of a user equipment (UE) in a spread spectrum wireless telecommunications system includes the steps of receiving multiple path energies of a wireless signal at a network interface unit of the UE. There is the step of processing the signal with either a rake receiver of the UE in communication with the network interface unit or an equalizer of the UE in communication with the network interface unit based on a predetermined criteria.

Abstract: Upon receiving a particular data unit by a receiving layer of a wireless device, it is detected that a previous data unit earlier in sequence to the particular data unit has not yet been received by the receiving layer. A timer is started in response to the detecting, where the timer has a time-out period that is variable dependent upon a parameter associated with receipt of the particular data unit. Upon expiration of the timer based on the timeout period, the receiving layer generates an error indication.
