Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of modulations for a random access message associated with a two-step random access channel (RACH) procedure. The set of modulations may be either a first set of modulations or a second set of modulations that is different from the first set of modulations. The set of modulations may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The UE may transmit the random access message based at least in part on the determined set of modulations. The random access message may include a physical uplink shared channel modulated using the determined set of modulations. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for random access channel (RACH) occasion assignment. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a plurality of synchronization signal blocks (SSBs), each SSB associated with a different transmit beam of the BS. The method further includes transmitting a random-access preamble on a first RACH occasion associated with a first SSB of the plurality of SSBs, wherein the first RACH occasion is one of a plurality of RACH occasions associated with the plurality of SSBs, wherein the first SSB is associated with a first number of the plurality of RACH occasions and a second SSB of the plurality of SSBs is associated with a second number of the plurality of RACH occasions, wherein the first number is different than the second number.

Abstract: Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, in a current cycle, information related to downlink transmission duplication on multiple component carriers, wherein each of the multiple component carriers is associated with a semi-persistent scheduling (SPS) configuration. The UE may monitor a subset of the multiple component carriers for a scheduled SPS occasion in one or more of the current cycle or a next cycle based at least in part on the information related to the downlink transmission duplication on the multiple component carriers in the current cycle. Numerous other aspects are provided.

Abstract: Aspects relate to implementing multiplexing with a single carrier waveform. In some examples, intra-symbol multiplexing of data and other information on a single carrier symbol may be implemented utilizing pre-discrete Fourier transform (DFT) multiplexing. In addition, time domain rate-matching may be performed on the data to rate-match the data around the other information based on a number of usable samples in the time domain within the symbol for the data.

Abstract: Techniques for reporting channel quality information (CQI) in a multi-carrier wireless communication system are disclosed. In one aspect, a user equipment determines one or more reporting groups, each comprising a plurality of component carriers which are configured for the user equipment. The user equipment may detect a trigger from a base station that selects a reporting group and may respond to the trigger by sending CQI for at least the activated component carriers in the selected reporting group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive information identifying a semi-persistent scheduling (SPS) configuration for a broadcast or multicast (broadcast/multicast) communication. The UE may receive the broadcast/multicast communication in accordance with the SPS configuration. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for wake-up resource randomization for discontinuous reception operation. An example method generally includes obtaining configuration information for receiving at least one wake up signal (WUS) during an OFF duration of a discontinuous reception (DRX) mode of the UE; monitoring, during a WUS monitoring occasion occurring during the OFF duration of the DRX mode, the one or more resources for the at least one WUS based on the configuration information; and transitioning to an ON state of the DRX mode when the at least one WUS is detected in the one or more resources during the monitoring; or remaining in an OFF state of the DRX mode when the at least one WUS is not detected in the one or more resources during the monitoring.

Abstract: In a method of wireless communication, a UE receives a configuration to receive a CIF for a serving cell of a plurality of serving cells. In addition, the UE monitors a PDCCH on a primary cell of the plurality of serving cells. Said primary cell is different than said serving cell. Furthermore, the UE assumes information received in the PDCCH is for said primary cell when the received information has a common payload size and is in a common search space with a first CCE index in the common search space being equal to a first CCE index in a UE specific search space.
