Abstract: A method, a computer-readable medium, and an apparatus are disclosed. The apparatus may be a UE. The apparatus may transmit, to a base station, an indication of a UE capability for PDCCH monitoring. The apparatus may configure, based on the UE capability for PDCCH monitoring, first MOs of a USS set to align with second MOs of a CSS set. The apparatus may monitor, based on the configuration, for a plurality of PDCCHs during PDCCH MOs. The PDCCH MOs may correspond to the first MOs or the second MOs. The first MOs of the USS set may be adjusted dynamically to be in same slots as the second MOs of the CSS set or to be within a predefined range of the second MOs of the CSS set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, during a channel occupancy time (COT) associated with one or more resources, via a no listen before talk (no-LBT) channel access mode. The WCD may initiate, after the COT, a reduced COT associated with the one or more resources, wherein the WCD is configured to reduce channel occupancy during the reduced COT. Numerous other aspects are described.

Abstract: A method for wireless communication by a user equipment (UE) determines a downlink/uplink (DL/UL) switching capability of the UE, and reports the DL/UL switching capability to a network. The DL/UL switching capability may indicate a quantity of DL/UL switch points, N, supported by the UE, and a time duration to which the quantity of DL/UL switch points is applied. The DL/UL switching capability may indicate a minimum link duration for which the UE should maintain a link direction after a previous DL/UL switch operation and before a next DL/UL switch operation. The DL/UL switching capability may include a DL/UL switching delay indicating a time specified for the UE to complete a DL/UL switching operation. The DL/UL switching capability may be based on a reference subcarrier spacing (SCS).

Abstract: A method of wireless communication, by a user equipment (UE) includes receiving, from a base station, a jointly trained artificial neural network. The method also includes calculating a value representing at least one of (1) a gradient estimate for a weight of the jointly trained artificial neural network, or (2) the weight of the jointly trained artificial neural network. The method further includes expanding the value into a numerical system with base N into a plurality of digits. The method also includes determining a number and/or a location of the plurality of digits to transmit based on a deterministic task assignment rule received from the base station or a probabilistic task assignment rule. The method further includes transmitting the determined number and/or the determined location of the plurality of digits to the base station.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting a beam to be allocated for transmitting downlink (DL) data to user equipment (UE). In some implementations, a UE receives a reference signal on each of a number of beams associated with a base station, and determines a delay spread value for each beam. The UE identifies each beam for which the determined channel delay spread value is less than a threshold value, and determines a reference signal received power (RSRP) level for each identified beam. The UE transmits an indication of the determined RSRP levels of the identified beams to the base station, and receives, in response to the transmitted indication, a selection of the beam to be allocated for DL transmissions to the UE.
