Abstract: In order to overcome problems that a UE may face in determining a default beam for communication with the base station during a COT, a method, apparatus, and computer-readable medium are provided for a base station to indicate to the UE which CORESET(s), QCL assumptions, UL resources, and/or spatial relationships are selected for a COT. A UE receives, from a base station, an indication corresponding to a COT. The indication is for at least one of a set of CORESETs, a set of QCL assumptions, a set of UL resources, or a set of spatial relations for determining a default beam. The UE determines the default beam from the base station for use during the COT based on the indication. The UE transmits or receives a transmission using the default beam.

Abstract: A configuration to allow for scheduling communication with a UE having associated characteristics based on a timing indication. The apparatus receives, from a UE, a timing indication associated with a bandwidth, a subcarrier spacing, or a waveform. The timing indication identifying a delay duration based on a processing timeline for the UE. The apparatus receives from the UE, or transmits to the UE, a first data channel having the bandwidth, the subcarrier spacing, or the waveform scheduled based on the timing indication. The first data channel is transmitted or received at a first time based on the timing indication.

Abstract: The present disclosure relates to apparatus and methods of monitoring a region by a transmitting device within a wireless medium for transmissions using at least one directional beam covering the region. Upon determining that the region in the wireless medium is free of transmissions, the transmitting device transmits to a plurality of wireless devices in the region using a plurality of spatially separated directional beams. Other aspects of the disclosure relate to apparatus and methods for receiving an instruction, e.g., at a user equipment (UE), to perform a channel assessment at a first time. The UE monitors a region within a wireless medium for transmissions after receiving the instruction. Upon determining that the region is free of transmissions, the UE may send an acknowledgment of the received instruction

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a capability of the UE to communicate one or more of uplink communications or downlink communications that include data-modulated demodulation reference signals (DMRSs) in which each of one or more resources of a plurality of resources of the uplink communications or the downlink communications carry both at least a portion of a DMRS sequence and data. The UE may transmit an uplink communication or receive a downlink communication that includes the data-modulated DMRSs. Numerous other aspects are provided.

Abstract: A method of wireless communication, by a user equipment (UE), includes receiving, from a first transmission and reception point (TRP) operating in a first band, assistance information comprising collocation information for both a second TRP operating in a second band and a communication node operating in the first band. The method also includes receiving, from the first TRP, configuration information for one or more reference signals (RSs) associated with the communication node. The method further includes communicating with the second TRP based on one or more features of the second band estimated from the one or more RSs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive scheduling information that schedules a shared channel that is associated with a first beamforming configuration; determine that a gap between the shared channel and a resource associated with a second beamforming configuration fails to satisfy a threshold, wherein the UE is configured to monitor the resource associated with the second beamforming configuration; and modify at least one of the gap to satisfy the threshold or the second beamforming configuration to match the first beamforming configuration based at least in part on determining that the gap fails to satisfy the threshold. Numerous other aspects are provided.

Abstract: Aspects are provided that allow a base station to provide a user equipment (UE) multiple timing opportunities to transmit an acknowledgment to a pre-grant (APG) after receiving a pre-grant for a downlink transmission. The base station transmits to the UE a pre-grant for a downlink transmission from the base station, the pre-grant triggering a plurality of timing opportunities for the UE to send an APG to the base station. The UE performs, after receiving the pre-grant, a clear channel assessment (CCA) during at least one timing opportunity of the plurality of timing opportunities. The UE transmits one or more APGs to the base station when the CCA is successful, and the UE receives the downlink transmission from the base station in response to the one or more APGs. The UE transmits the one or more APGs to the base station until the downlink transmission is received from the base station.

Abstract: Aspects are provided which improve LBT by associating contention windows with transmission burst lengths and by allowing contention windows and maximum burst lengths to be adjusted based on interference activity. For downlink, a UE receives a PG for a downlink transmission from a base station indicating a CCA length based on a contention window size associated at least with a burst length for the downlink transmission. The UE performs, after receiving the pre-grant, a CCA based on the CCA length, transmits an APG to the base station when the CCA is successful, and receives the downlink transmission in response to the APG. For uplink, the base station performs a CCA based on a contention window associated at least with a burst length for an uplink transmission, transmits an uplink grant to the UE when the CCA is successful, and receives the uplink transmission in response to the uplink grant.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for managing beam selection. In one aspect, an initiating wireless device may determine whether a pre-grant acknowledgement associated with a first beam has been received from a responding wireless device within an expected receive time. The initiating wireless device may generate an indication to prevent the initiating wireless device from using the first beam for a blocking duration in response to determining that the pre-grant acknowledgement associated with the first beam has not been received within the expected receive time.

Abstract: A UE configured to report resources, such as beams, to a base station may be unaware of the context or purpose for which the UE is reporting such resources. As different resources may provide different performance and/or quality when used in different contexts, the resources reported by the UE may provide lower quality and/or performance in one context relative to some other unreported resources. In order to improve resource reporting by the UE, the UE may be informed of an operational mode and/or a criteria based upon which the UE may select resources to report. The UE may report such selected resources to the base station in a group-based beam report. The base station may then configure communication with the UE based on the reported resources.
