摘要： A method includes calculating a set of first metrics using channel information and one or more precoders, where each of the first metrics corresponds to a respective set of a plurality of sets of codebook precoders, and selecting, based on the set of first metrics and a first selection criteria, a set of codebook precoders from the plurality of sets of codebook precoders. The method also includes, in response to selecting the set of codebook precoders, calculating a set of second metrics and selecting, based on (i) the set of second metrics and (ii) a second selection criteria, a codebook precoder from the selected set of codebook precoders. Each of the second metrics is calculated using a respective codebook precoder in the selected set of codebook precoders. The method also includes causing the selected codebook precoder to be applied to a signal to be transmitted to a communication device.

摘要： Systems, methods, apparatus, and techniques are provided for retransmitting packets of data. A Radio Link Control (RLC) layer data packet is generated, and the RLC layer data packet is converted to one or more physical (PHY) layer data packets. The one or more PHY layer data packets are transmitted. At least one of a hybrid automatic transmission request (HARQ) acknowledgement (ACK) message and a HARQ negative acknowledgment (NACK) message is received from a receiver in response to transmission of the one or more PHY layer data packets. It is determined whether the at least one of the HARQ ACK message and the HARQ NACK message represents a automatic transmission request (ARQ) ACK message or a ARQ NACK message.
