Abstract: An exemplary method of communicating includes determining a first user channel estimate from a communication comprising first and second user reference sequences. The first user reference sequence is reconstructed using the determined first user channel estimate. The communication is revised based upon the reconstructed first user reference sequence. Then determining a second user channel estimate is based on the revised communication.

Abstract: In a UMTS wireless communication system, the enhanced dedicated physical control channel (E-DPCCH) that is usually always transmitted together with the enhanced dedicated physical data channel (E-DPDCH) on the uplink from a UE to a NodeB is instead only transmitted when a predetermined “start criterion” is met and is turned off when a predetermined “stop criterion” is met until a “start criterion” is later met again. The UE starts transmitting E-DPCCH whenever the corresponding E-DPDCH transport format combination is different from the previous one in the same HARQ process or some other “start criterion” is met. Multiple mechanisms can be used to decide when the UE should switch off E-DPCCH transmission after the transport format combination of E-DPDCH has changed.

Abstract: A sector switch detection method incorporates two independent, concurrent switch detection processes within a sector switch detection block. A frame-based switch detection process operates over a given single period, while a sliding window-based detection system operates over a selected multiple of periods.

Abstract: In a method of canceling interference, a base station selects a known highest data rate user transmission from a received first signal containing a group of user transmissions. The known highest rate user transmission may be configured as one or more frames, each frame including a control preamble and a plurality of encoded sub-frames. The control preamble and encoded sub-frames may be decoded, and the decoded sub-frames may be used for removing interference caused by the known highest rate user transmission to all remaining transmissions of the group.

Abstract: In the absence of a continuous channel from the mobile terminal that incorporates a CRC in each transmitted frame from which the base station can derive a power control signal for feedback to the mobile station for maintaining the mobile station's pilot Eb/N0 level at a desired target that corresponds to a particular frame error rate, the pilot signal received by the base station from the mobile terminal itself is arranged in a frame format. Each pilot frame is compared with an a prioi known transmitted pilot signal bit pattern to determine whether it has been received in error. In response to a comparison of a received pilot frame with the expected known bit pattern of the pilot frame, an error signal is derived, which in the described embodiment is either a step-up or step-down signal that is fed back to the mobile terminal to increase or decrease its transmitted pilot Eb/N0 level, respectively.

Abstract: A DTX detection method evaluates soft symbols from a decoding process to evaluate whether a checksum error is caused by an erasure condition or a DTX condition. The inventive method divides the soft symbols or a function of the soft symbols by a normalizing factor that greatly reduces the effect of the overall magnitude of the channel estimates that are used to calculate the soft symbols, restoring a value proportional to the received symbol energy. The method then evaluates this value, rather than the unnormalized value, to determine whether a checksum error for the frame is caused by a DTX condition or an erasure condition. Normalizing the soft symbols to obtain a metric proportional to the actual symbol energy greatly reduces the effect of the overall channel level on DTX detection, making it easier to distinguish between DTX cases and erasure cases.
