Abstract: Information is communicated via a plurality of communication opportunities of a semi-persistent scheduling (SPS) occasion. A base station may transmit first information via a first communication opportunity of an SPS occasion and transmit second information via a second communication opportunity of that same SPS occasion. A wireless communication device may monitor all communication opportunities of an SPS occasion to decode the information sent in two or more of the communication opportunities of the SPS occasion.

Abstract: This disclosure provides systems, methods and apparatus for cellular communications. In one aspect, a UE determines an FFP of a cell signal for the UE in a frame based equipment mode, determines one or more SSB positions in the cell signal based on the FFP, and performs radio management of the UE based at least in part on the one or more invalid SSB candidate positions. Performing radio management may include using one or more SSB positions in the FFP exclusive of the one or more invalid SSB candidate positions. Radio management may include PDSCH rate matching, radio link monitoring or measurement, or radio resource management. In some implementations, the one or more SSB positions are SSB positions after a first eight SSB positions in an FFP. In some other implementations, the one or more SSB positions are SSB positions that at least partially overlap an idle period between FFPs.

Abstract: Wireless communications systems and methods related to wireless communications are provided. A first wireless communication device may communicate with a second wireless communication device, a first power mode configuration including a first transmit power parameter and a first communication signal based on the first power mode configuration. The first wireless communication device may communicate with a second wireless communication device, a second power mode configuration including a second transmit power parameter different from the first transmit power parameter and a second communication signal based on the second power mode configuration.

Abstract: Methods, systems, and devices for wireless communications are described. One method of dynamically mapping encoded packets may include a base station identifying a set of encoded packets from a set of source packets. The base station may map subsets of the encoded packets onto a first and a second set of resources using different coding rates. In some examples, the base station may schedule one or more resources from the second set of resources for receiving feedback from one or more user equipments (UEs). In some examples, the base station may identify a second set of encoded packets from a second set of source packets and may map the second set of encoded packets onto the second set of resources and a third set of resources. A UE may recover the first or second sets of source packets based on the encoded packets transmitted by the base station.

Abstract: A method for wireless communications is presented. The method may be performed by a user equipment (UE) and includes receiving a multi-user physical (MUP) downlink shared channel (PDSCH) communication (MUPC) comprising a number of payloads. The method also includes transmitting an acknowledgement (ACK) in response to decoding the MUPC. The method further includes receiving a message requesting retransmission of at least one payload of the number of payloads. The method still further includes transmitting the at least one payload in response to the message.

Abstract: A communication configuration is selected based on the bandwidth used by a wireless communication device during a random access procedure (e.g., on an unlicensed band). In some scenarios, the maximum transmit power that the wireless communication device can use may be significantly restricted (e.g., by a regulation). In some cases (e.g., when the wireless communication device is near a center of a cell), the wireless communication device may transmit the random access information using a default bandwidth. In other cases (e.g., when the wireless communication device is near a cell edge), the wireless communication device may transmit the random access information using a wider bandwidth (e.g., to increase the coverage of the transmission). In some aspects, the maximum bandwidth used for the random access procedure may be used to select at least one communication configuration that is used for a subsequent communication (e.g., data or control signaling).

Abstract: Wireless communications systems and methods related to determining the HARQ process ID for a subset of HARQ processes in a configured grant resource are provided. A first wireless communication device determines a starting hybrid automatic repeat request (HARQ) process identifier (ID) for HARQ processes for communicating in a configured grant resource including a number of slots N, each slot of the N number of slots including a number of physical uplink shared channels (PUSCHs) M, and a repetition factor K, wherein N, M, and K are integers greater than or equal to one (1), and the first wireless communication device communicates with a second wireless communication device a first communication associated with the determined starting HARQ process ID.
