    Abstract: Apparatuses, systems, and methods for user equipment device (UE) uplink antenna panel selection. The UE may determine, based on at least one condition, to perform a beam switch from a current beam being used for communications with a base station. The UE may transmit, to the base station, an indication of an antenna panel status that may include an indication of a latency associated with the beam switch. The UE may receive, from the base station, an indication to switch to a target beam and to perform the switch, based on the indication, to the target beam. The indication of the antenna panel status may include a beam switching latency level for each beam in a beam report, a beam switch request that may indicate the target beam, and/or a beam switch request that may indicate that an antenna panel switch is to be applied by the UE.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

    Abstract: Apparatuses, systems, and methods for providing downlink control for multi-TRP transmission. A cellular base station may provide a downlink control information transmission to a wireless device scheduling downlink transmissions to the wireless device from multiple transmission reception points. The downlink control information may include information that can be used by the wireless device to determine any or all of physical resource block bundling sizes, frequency domain resource allocations, modulation and coding schemes, redundancy versions, phase tracking reference signal configurations, and any of various other possible types of configuration information for the downlink transmissions. The wireless device may receive the downlink transmissions from the plurality of transmission reception points in accordance with the downlink control information.

    Abstract: Methods to enhance the coverage of NR systems for coverage-limited wireless devices are disclosed. A serving base station may configure a coverage-limited UE with parameters for the UE to operate in a coverage enhancement mode through RRC signaling, DCI, or RAR grant. The UE may use the configuration parameters to determine whether to enter into the coverage enhancement mode when connecting and communicating with the serving base station. The configuration parameters may configure the UE to exploit both time diversity and frequency diversity to extend and enhance coverage when receiving the PDSCH and PDCCH channels, when transmitting the PUSCH and PUCCH channel, and when transmitting PUSCH Msg3 during random access. Advantageously, the base station may flexibly and dynamically configure the UE with coverage enhancement parameters to extend the coverage of the UE using time diversity and frequency diversity gains as the UE moves around.
