Abstract: Methods, systems, and devices for wireless communications are described that provide for determining downlink control resources for transmitting control information to a user equipment (UE) that indicates downlink resources for a downlink transmission and a number of repetitions of the downlink transmission. The control information may be provided in a first transmission time interval (TTI), and the repetitions may span a number of TTIs. The UE may rate-match a shared channel containing the downlink transmission around the downlink control resources of the first TTI, and also perform the same rate-matching around corresponding resources in each subsequent TTI of the plurality of TTIs.

Abstract: A spatial multiplexing configuration may enable a user equipment (UE) to spatially multiplex two or more uplink channels of different types for simultaneous transmission. For example, a UE may receive an indication of a spatial multiplexing configuration from a base station. The UE may identify two or more uplink channels for simultaneous transmission on a same component carrier, where each uplink channel may be a different type. In such cases, the UE may spatially multiplex the two or more uplink channels on a same set of time/frequency resources on the component carrier in accordance with the spatial multiplexing configuration. The spatially multiplexed uplink channels may then be simultaneously transmitted by the UE on the set of resources, where the spatially multiplexed uplink channels may be simultaneously sent to the same base station or to different base stations. Additionally, different spatial parameters may be applied to each uplink channel.

Abstract: A user equipment (UE) may apply transmit power control (TPC) commands and transmit uplink information based on received downlink control information (DCI). A UE may receive multiple DCI messages including multiple TPC commands for an uplink transmission. The power level for the uplink transmission may be adjusted based on the combination of TPC commands. For example, the TPC commands may be considered together (e.g., added, averaged, etc.), the latest TPC command may be used, etc. In some cases, a change in TPC command for an uplink transmission (e.g., from a previous TPC command for the uplink transmission indicated via other DCI) may indicate a change in one or more transmission attributes for the uplink transmission. In some cases, a UE may receive a grant for a prioritized transmission, resulting in discontinuous transmission (DTX) of a previous transmission, which may result in TPC modification by the UE.

Abstract: Methods, systems, and devices for wireless communications are described for controlling multiplexing of a reference signal on an uplink shared channel (UL-SCH). In an implementation, a user equipment (UE) may time division multiplex (TDM) a demodulation reference signal (DMRS) with other signaling across symbol periods of one or more allocated resource blocks. The UE may map the DMRS to resource elements of one or more symbol periods within the allocated resource blocks. The UE may then map uplink control information (UCI) to one or more symbol periods different than the symbol periods of the DMRS mapping. In some cases, the DMRS, UCI, or both may be frequency interleaved with UL-SCH data for the allocated resource blocks. The UE may generate and transmit an uplink waveform for transmission within the allocated resources of the uplink shared channel.

Abstract: Certain aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for dynamically triggering or skipping channel state feedback (CSF). A method that may be performed by a user equipment (UE) includes receiving, from a network entity, a configuration indicating CSF reporting occasions, receiving a downlink (DL) transmission, and transmitting CSF on only some CSF reporting occasions after receiving the DL transmission when one or more trigger conditions are met. According to certain aspects, when one or more trigger conditions are not met, the UE skips at least some CSF reporting occasions.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on a weighted number of UEs that is based at least in part on respective resource utilizations by the UEs, a resource utilization limit for the UE. The UE may selectively transmit a communication based at least in part on the resource utilization limit for the UE. 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 detect, using a low-power receiver of the UE, a low-power synchronization signal (LP-SS) that is associated with a first coverage area that is larger than a second coverage area associated with a legacy synchronization signal block. The UE may monitor, using the low-power receiver, for a low-power wake up signal, based at least in part on the LP-SS, that is associated with a third coverage area that is larger than a fourth coverage area associated with a legacy wake up signal. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques for multiplexing high priority uplink control information (UCI) and low priority UCI on a physical uplink control channel (PUCCH). A method includes determining a total number of resource blocks to transmit encoded UCI bits based on a quantized payload size of a second one or more encoded UCI bits of a second priority and a non-quantized payload size of a first one or more encoded UCI bits of a first priority. The method generally includes mapping the second one or more encoded UCI bits to a first number of resource elements associated with the quantized payload size and the first one or more encoded UCI bits to a second number of REs and transmitting the encoded UCI bits in a PUCCH in accordance with the mapping.

Abstract: Techniques related to multiplexing uplink control information (UCI) onto a multi-transport block (TB) physical uplink shared channel (PUSCH) transmission are disclosed. Some aspects of the disclosure relate to devices and methods for wireless communication where a user equipment (UE) receives an uplink grant for a PUSCH transmission having a plurality of TBs, each being associated with a respective TB priority index. The UE then transmits the PUSCH including the plurality of TBs. The UE may further transmit a plurality of UCIs multiplexed with the PUSCH, where each UCI is associated with a respective UCI priority index. Other aspects, embodiments, and features are also claimed and described.
