Abstract: Methods, systems, and devices for wireless communications are described in which UEs and base stations may transmit multiple repetitions of certain communications, which may enhance the likelihood of successful reception and decoding such communications. A base station may configure a UE to transmit multiple repetitions of uplink control information (UCI) that each use a same number of coded bits for each repetition, which may allow for soft buffering and combining of the multiple repetitions the base station. The UE may select one of the repetitions for determining the number of coded bits, and may adjust one or more other repetitions of the UCI to provide the same number of coded bits.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to perform physical downlink control channel (PDCCH) monitoring in a first monitoring span, of a first group of slots, and in a second monitoring span, of a second group of slots, wherein a start of the first monitoring span is at least a threshold number of slots away from a start of the second monitoring span. The UE may selectively perform the PDCCH monitoring in the first monitoring span or the second monitoring span based at least in part on the indication. Numerous other aspects are described.

Abstract: A user equipment (UE) and a base station (BS) may transmit reference signals (RS) for the other device to estimate a channel and perform measurements. This disclosure provides for a UE to request a reference signal such as a channel state information (CSI) or a sounding reference signal (SRS). The BS transmits a radio resource control (RRC) message that configures the UE with one or more trigger states for CSI, SRS, or a combination thereof and a media access control (MAC) control element (CE) that activates a subset of the configured trigger states. In one aspect, the UE transmits an uplink request that indicates a trigger state for the UE. corresponding to at least one configured RS. The UE and the BS communicate the at least one RS corresponding to the trigger state for example, based on a grant from the BS or a time offset from the uplink request.

Abstract: Wireless communication systems and methods related to random access in a wireless communication network are provided. A user equipment (UE) receives a configuration indicating a random access preamble for a random access associated with multiple random access occasions (ROs). The UE transmits the random access preamble in one or more of the multiple ROs. The UE determines one or more random access-radio network temporary identifiers (RA-RNTIs) for the multiple ROs. The UE monitors for a random access response (RAR) message based on the one or more determined RA-RNTIs in a RAR window associated with the multiple ROs.

Abstract: Wireless communications systems and methods related to resource block set allocation for dynamic uplink communications in a wireless communication network are provided. For example, a method of wireless communication performed by a user equipment can include: monitoring, in a search space of a shared radio frequency band, for downlink control information (DCI); receiving, from a base station based on the monitoring, the DCI, wherein the DCI includes an explicit interlace allocation but does not include an explicit resource block set allocation; determining, based on the received DCI, one or more resource block sets for transmitting an uplink communication; and transmitting, to the base station, the uplink communication using the one or more resource block sets and the explicit interlace allocation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may identify multiple physical uplink control channel (PUCCH) resources in a single slot that are to be used for multiple repetitions of an uplink communication; and transmit one or more of the multiple repetitions of the uplink communication using one or more of the multiple PUCCH resources, or one or more other resources, in the same slot based at least in part on identifying the multiple PUCCH resources. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for selecting resources from a set of resources that are semi-persistently scheduled according to a first periodicity based on a supplemental configuration including a second periodicity. A base station and a user equipment (UE) may select resources for transmitting or receiving instances of one or more semi-persistently scheduled transmissions based on selecting resources from the set of resources based on the second periodicity and one or more selection criteria. In some examples, the base station and the UE may select an earliest resource or a next available resource of the set of resources with a period associated with the second periodicity. In some other examples, the base station and the UE may randomly select a resource of the set of resources within a period associated with the second periodicity.

Abstract: Certain aspects of the present disclosure provide techniques for subchannel-based listen before talk (LBT). An example method that may be performed by a user equipment (UE) includes receiving one or more transmissions indicating one or more allocated subchannels of a frequency band that are allocated during a first time period, the frequency band comprising the one or more allocated subchannels and one or more unallocated subchannels during the first time period; sensing the one or more unallocated subchannels for at least a portion of the first time period prior to a second time period; and transmitting a signal within the frequency band during the second time period based on energy sensed for the one or more unallocated subchannels being less than a threshold.
