Abstract: Techniques are described for wireless communication. One method includes segmenting a payload into a plurality of code blocks; generating, for each code block, a cyclic redundancy check (CRC); encoding each code block and associated CRC in one or more codewords of a plurality of codewords; and transmitting the codewords. The encoding is based at least in part on a low density parity check code (LDPCC) encoding type. Another method includes receiving a plurality of codewords associated with a payload encoded using a LDPCC encoding type; decoding a set of the codewords associated with the first payload and a CRC; and transmitting one of an acknowledgement (ACK) or a non-acknowledgement (NAK) for the set of the codewords.

Abstract: Methods, systems, and devices for wireless communication are described. A base station supporting multimedia broadcast multicast service (MBMS) and operating in a shared radio frequency spectrum band may map MBMS transport blocks (TBs) to each carrier in the system bandwidth. The device may perform a clear channel assessment (CCA) on one or more of the carriers, and transmit a portion of the MBMS TBs on carriers with successful CCAs. The portion of the MBMS TBs mapped to carriers with unsuccessful CCAs may be punctured. In various examples, a single TB may be mapped across the carriers, different TBs may mapped to each carrier, or redundancy versions (RVs) may be mapped to each carrier. A region at the frequency boundary of each carrier may be reserved for a guard region, and may not be used for MBMS transmissions when a carrier is associated with a failed CCA.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a wireless device may identify a set of at least two wireless communications channels that are available for communication with another wireless device. In some examples, the wireless device may identify at least one channel of the set, and may select integrity check information that indicates the identified wireless channel(s) that are available. The wireless device may then transmit the integrity check information during a first time period. In some examples, a wireless device may receive wireless communication that includes integrity check information on a subset of channels. The wireless device may then determine, based on the integrity check information, whether the identified subset of channels is the same as the actual subset of channels used for transmission of the wireless communications.

Abstract: Aspects of the present disclosure provide wireless communication devices and methods configured to operate with multiple active connections. A user equipment establishes a first active connection associated with a first subscription. The user equipment also establishes a second active connection, simultaneous to the first active connection, associated with a second subscription. The user equipment provides modem information corresponding to connection qualities of the first active connection and second active connection, to an operating system of the user equipment. Furthermore, the user equipment mitigates contention between the first active connection and second active connection by degrading at least one of the first active connection or second active connection in accordance with a decision given by the operating system based on the modem information.

Abstract: Methods, systems, and devices for soft hybrid automatic repeat request operation in wireless communication are described. A user equipment (UE) may fail to decode a received signal, for example. The UE may store a portion of the signal in a buffer if the signal size is greater than the buffer size; otherwise, the UE may store the entire signal in the buffer. The UE may then receive a second signal and combine the second signal with the stored portion of the first signal; the combined signal may be larger than the buffer size. This combined signal may, for example, have a code rate less than the first signal. The UE may perform a second decoding attempt on the combined signal. The UE may determine that the second decoding attempt failed and may store a portion of the combined signal in the buffer.
