  • Publication number: 20230108535
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may report, to a base station, a capability of the UE to support interleaving physical uplink shared channel (PUSCH) messages. The base station may schedule two or more PUSCH transmissions having temporally overlapping durations based on the reported capability of the UE, and the UE may transmit interleaved PUSCH messages scheduled by the base station. In some cases, demodulation reference signal (DMRS) bundling may be enabled for PUSCH transmissions. A UE may be incapable of both performing DMRS bundling for PUSCH transmissions and transmitting interleaved PUSCH transmissions. In some case, a UE may disable DMRS bundling, drop a scheduled PUSCH transmission, transmit PUSCH messages sequentially (e.g., not interleaved), and/or indicate an error to the base station if the UE receives uplink grants scheduling two or more PUSCH transmissions having temporally overlapping durations.

  • Patent number: 11611379
    Abstract: Methods, systems, and devices for wireless communications are described in which a base station may identify a null space matrix that lies within a null space of an effective channel matrix for communications between the base station and a user equipment (UE). An indication of the null space matrix may be provided to the UE, and the null space matrix used to determine modifications to a precoding matrix. The base station and UE may determine a redistribution matrix that provides a reduced variance of transmission powers for a number of transmission channels, where a product of the null space matrix and the redistribution matrix may be computed and added to the precoding matrix to generate a modified precoding matrix. The modified precoding matrix may be used to generate the communications from the base station and UE with reduced power variance across channels.

  • Publication number: 20230072214
    Abstract: User Equipment (UE) receives, from a base station (BS), at least one resource block (RB). The RB includes at least one reference signal (RS) resource element (RE) of a first physical channel of the UE. The UE estimates a channel quality of a second physical channel of the UE as a function of the at least one RS RE. In some examples, the BS associates the transmission of a first physical channel reference signal (RS) and the transmission of a second physical channel RS. The BS then signals, BS to the UE, the association between the first physical channel reference signal and the second physical channel reference signal.

  • Patent number: 11601930
    Abstract: Aspects are provided allowing a UE to perform early termination of repetitions of an ongoing PUSCH transmission in response to a DCI from a base station indicating whether a prior PUSCH transmission or repetition was successfully decoded. The UE obtains information configuring an uplink data transmission and a repetition of the uplink data transmission. The UE sends the uplink data transmission to a base station. The UE terminates the repetition of the uplink data transmission in response to reception of downlink information in a downlink control channel. Thus, UE power reduction and enhanced resource efficiency may be achieved. Moreover, the repetition is terminated after a time gap following a CORESET where the downlink control channel is received. As a result, a start time for terminating PUSCH repetitions may be configured to accommodate various timing considerations such as dynamic TDD, different numerologies between PDCCH and PUSCH, and multiple PUSCH processing capabilities.
