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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a downlink control information (DCI) communication that schedules a physical downlink shared channel (PDSCH) including a first transmission occasion and a second transmission occasion; and determine a mapping type for the first transmission occasion and a mapping type for the second transmission occasion based at least in part on receiving the DCI communication scheduling the PDSCH including the first transmission occasion and the second transmission occasion. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatuses for identifying physical downlink control channel (PDCCH) parameters, such as a PDCCH blind decode limit and a PDCCH control channel element limit, for implementations where a user equipment (UE) is configured with two or more cell groups. The techniques described herein permit the UE or a base station to determine the quantity of cell groups that is to be considered when determining the PDCCH parameters, permit the UE to indicate PDCCH capability values across multiple frequency ranges, and permit the base station to schedule a quantity of PDCCHs for the UE that results in a quantity of blind decodes that exceeds a PDCCH blind decode limit or a quantity of control channel elements that exceeds a PDCCH control channel element limit.

Abstract: The present disclosure relates to methods and devices for wireless communication. Aspects of the present disclosure can determine a matrix or Hadamard matrix associated with signal transmission, the matrix or Hadamard matrix including M rows and M columns. Also, aspects of the present disclosure can determine a sampling function for generating a set of sequences from the matrix or Hadamard matrix. Aspects of the present disclosure can also generate the set of sequences by sampling one of a set of rows or a set of columns based on the determined sampling function. Aspects of the present disclosure can also transmit a signal derived based on at least one sequence of the set of sequences.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify, when using carrier aggregation and a plurality of component carrier groups, first traffic associated with a first service type and second traffic associated with a second service type for concurrent transmission. The user equipment may transmit, concurrently, the first traffic associated with the first service type using a first component carrier group of the plurality of component carrier groups, and the second traffic associated with the second service type using a second component carrier group of the plurality of component carrier groups. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may generate a Reed Muller generating matrix for an information bit vector that includes a plurality of information bits. The wireless communication device may remove, from the Reed Muller generating matrix, a row vector consisting of all 1-values to form a modified Reed Muller generating matrix. The wireless communication device may encode the information bit vector using the modified Reed Muller generating matrix to form a codeword. The wireless communication device may transmit the codeword without transmitting a pilot signal or demodulation reference signal for the codeword. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that one or more measurement reference resources, of a plurality of measurement reference resources, are preempted; and, based at least in part on the determination, selectively: cancel transmission of a measurement report, or transmit the measurement report based at least in part on at least a portion of the plurality of measurement reference resources. In some aspects, the UE may determine that one or more uplink reference signal resources, of a plurality of uplink reference signal resources, are to be preempted; and, based at least in part on the determination, selectively: cancel transmission of an uplink reference signal, or transmit the uplink reference signal based at least in part on at least a portion of the plurality of uplink reference signal resources. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing beam configurations and parameters for non-terrestrial networks. In some implementations, a UE may detect a synchronization signal block (SSB) transmitted by a satellite via a first beam. Aspects of the present disclosure recognize that each beam may be identified by a unique SSB index based at least in part on a time or frequency on which the SSB is received. Thus, the SSB may be identified based on a frequency-domain SSB index or a time-domain SSB index. The UE may further determine one or more wireless communication parameters associated with the first beam. The UE may generate a mapping between the SSB and the wireless communication parameters associated with the first beam, and thereafter communicate with the satellite using the mapping.
