Abstract: Disclosed is a method of wireless communication. The method is performed at a first wireless node. The method comprises: obtaining a sequence of bits to be encoded, selecting a puncturing pattern from a plurality of puncturing patterns, generating, based on the sequence of bits to be encoded, a sequence of parity bits in accordance with a binary linear block coding scheme, puncturing, based on the selected puncturing pattern, at least one of the sequence of bits to be encoded or the sequence of parity bits, generating a plurality of modulation symbols based on remaining bits in the sequence of bits to be encoded and based on remaining bits in the sequence of parity bits, and transmitting, to a second wireless node, the plurality of modulation symbols.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may update a noise estimation (e.g., a noise covariance matrix, a log likelihood ratio (LLR) scaling, or both) for communications with a serving base station to account for interference from a neighboring base station operating according to a different radio access technology (RAT). For example, the UE may identify a transmission status of a base station operating according to a first RAT, such as long term evolution (LTE), that shares a radio frequency spectrum with a serving base station operating according to a second RAT, such as new radio (NR). The UE may measure the interference from the LTE base station and may update a noise estimation according to the measured interference. The UE and the serving base station may communicate based on the updated noise estimation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to decode or refrain from decoding a transport block (TB) transmitted from a base station based on a decodability condition. The decodability condition may include whether an effective UE throughput for decoding the TB is greater than a predetermined decoding throughput threshold or not. If the effective UE throughput is greater than the predetermined decoding throughput threshold, the UE may refrain from decoding the TB. In some cases, the TB may be a subsequent transmission from the base station based on an initial transmission not being correctly decoded, and the UE may refrain from decoding the subsequent transmission.

Abstract: Systems, methods and apparatus select a code book based on channel conditions and performance of a demodulator or demapper in a wireless receiver. The method may include determining that the receiver in a first wireless communication apparatus is configured for iteratively processing signals received from a channel, selecting a code book for use in communicating over the channel based on conditions affecting transmission of the signals through the channel and performance information associated with a demapper in the receiver, and identifying the selected code book in one or more control channels transmitted to a second wireless communication apparatus.
