Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, CC1 may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and CC2 may be an assisting carrier such as a sub-6 GHz carrier. In a first example, a UE may trigger beam recovery for CC1 (on CC2), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on CC2. In a second example, a new scheduling request (SR) may be defined on CC1 for CC2 beam recovery. In a third example, RACH resources or procedures on CC2 may be used to perform the beam recovery for CC1.

Abstract: The present disclosure relates to mitigating collision between reference signals and direct current subcarriers both occupying at least a same resource element of a resource block. Specifically, a UE may at least adjust a DMRS pattern within the resource block based on determining an upcoming occurrence of the collision between the DMRS and the DC subcarrier. Further, a network entity may determine that the UE should transmit the DMRS according to an adjusted DMRS pattern and transmit the adjusted DMRS pattern to the UE on a downlink communication channel.

Abstract: A method for communication includes a user equipment (UE) periodically awakening to monitor for a wake-up signal (WUS) in a wake-up signal search space, the wake-up signal having a shorter length than a length of a control channel communication to allow the UE to determine whether the UE should monitor for the control channel communication.

Abstract: Aspects herein describe determining a channel format for transmitting uplink communications in a slot, wherein the channel format is selected from multiple channel formats based at least in part on a payload size of the uplink communications, determining a starting symbol and an ending symbol of an uplink channel duration of the slot for transmitting the uplink communications, determining, based at least in part on the starting symbol and the ending symbol, a portion of the channel format to utilize in transmitting the uplink communications in the slot, and transmitting the uplink communications in the slot, wherein transmitting the uplink communications is based on the portion of the channel format.

Abstract: A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.

Abstract: Aspects of the present disclosure describe determining an uplink channel raster for determining frequency location of an uplink channel over which to transmit uplink communications to a base station. Uplink communications can be transmitted to the base station over the uplink channel. The uplink channel raster can be shifted, in frequency, with respect to a legacy uplink channel raster of a legacy communication technology to facilitate coexistence, in an uplink carrier, of the uplink channel and one or more uplink channels of the legacy communication technology.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for applying rules to determine when to retune radio components of a user equipment (UE). Certain aspects of the present disclosure provide a method for wireless communications by a UE. The method includes determining first resources assigned to the UE in a first subframe and second resources assigned to the UE for uplink transmissions in a second subframe. The method further includes determining whether to retune radio frequency (RF) circuitry prior to transmitting in the second subframe based on at least one rule involving an overlap between the first resources and second resources.
