摘要： A method and system for determining synchronization status in a wide band CDMA (WCDMA) network may comprise calculating a signal to noise ratio (SNR) of a downlink dedicated physical channel (DPCH) based on a plurality of transmit power control (TPC) bits received via the downlink dedicated physical channel (DPCH), wherein the value of at least one of the plurality of TPC bits is not known when at least one of the plurality of TPC bits is received. The transmit circuitry may be controlled based on the calculated signal to noise ratio. The transmit circuitry may be disabled if the calculated SNR of the plurality of TPC bits is below a first channel threshold. The transmit circuitry may be enabled if the calculated SNR of the plurality of TPC bits is above a second channel threshold.

摘要： Aspects of a method and system for determining a limited soft buffer size on transport blocks for rate matching are provided. A data stream may be processed for transmission between a base station (eNodeB) and a UE via HARQ procedures. A two-stage rate-matching algorithm may be used in the HARQ procedures. A limited virtual soft buffer size at the UE in the two-stage rate-matching algorithm may be calculated on site based on channel condition information, available channel bandwidth, number of layers in spatial multiplexing, and the capacity of the UE, respectively. The data stream may be first rate-matched to the calculated limited soft buffer size available at the UE, and forwarded for second stage rate-matching to an actual physical channel size determined by the base station. The amount of bits forwarded for second stage rate-matching may equal to the calculated limited virtual soft buffer size of the virtual soft buffer.
