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: Apparatus, methods, and computer-readable media for wideband uplink control channel capability indication during initial access are disclosed herein. A user equipment (UE) may transmit an uplink message indicating an uplink resource bandwidth capability of a physical uplink control channel (PUCCH) of the UE based on a power spectral density (PSD) limitation and a maximum transmission power of the UE. The UE may receive a downlink message indicating an uplink resource allocation of the PUCCH corresponding to the uplink resource bandwidth capability. Alternatively, the UE may receive a downlink configuration that indicates a first set of uplink resources and a second set of uplink resources. The UE may transmit an acknowledgment message in response to a downlink message of a random access channel process. The acknowledgment message includes the uplink resource bandwidth capability that indicates a selection between the first set of uplink resources and the second set of uplink resources.

Abstract: Aspects of methods, computer-readable mediums, and apparatuses are provided for a user equipment (UE) or a base station. The UE receives, from a base station, an indication to transmit a scheduling request (SR). The UE receives a downlink transmission triggering hybrid automatic repeat request (HARQ) feedback in one or more physical uplink control channel (PUCCH) resources. The UE transmits the SR to the base station in the one or more PUCCH resources for the HARQ feedback. The base station transmits, to a UE, an indication to transmit an SR. The base station transmits a downlink transmission triggering HARQ feedback in one or more PUCCH resources. The base station receives the SR from the UE in the one or more PUCCH resources.

Abstract: Methods and apparatus for managing reuse of a wireless medium are provided. One method of managing reuse of a wireless medium includes determining, at an access point, whether to allow reuse of the wireless medium by one or more stations in a basic service set (BSS). The method further includes transmitting, upon determining to allow reuse, an indication that reuse of the wireless medium can be permitted for stations meeting a criteria. The method further includes determining one or more reuse parameters. The method further includes transmitting the one or more reuse parameters.

Abstract: The present disclosure provides techniques for configuring the utilization of request-to-send/clear-to-send (RTS/CTS) protocol procedures based on varying conditions at the STA. For example, an AP may identify one or more conditions, when satisfied, may trigger the STA to either enable or disable uplink (UL) transmissions associated with a RTS/CTS protocol procedure. In some aspects, an AP may determine a transmit opportunity (TXOP) threshold for an STA and may determine whether to broadcast a message having the TXOP threshold to multiple STAs including the STA or unicast the message to the STA. An STA may receive a message from an AP having a TXOP threshold and may replace, based on an indication in the received message, a current TXOP threshold in the STA with the TXOP threshold in the received message. The STA may transmit an UL RTS frame in response to a determination that a planned TXOP duration satisfies the TXOP threshold.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to bandwidth dependent carrier sensing for orthogonal frequency division multiple access (OFDMA). One example apparatus for wireless communications generally includes a first interface for obtaining at least a first frame with an indication of a time duration during which at least one bandwidth channel is occupied; a processing system configured to track, based at least in part on the indicated duration, availability of time and one or more resources on a plurality of bandwidth channels including the at least one bandwidth channel and to determine whether resources are available to transmit at least a second frame, based on the tracked availability; and a second interface for outputting the second frame for transmission if the determination indicates resources are available.

Abstract: Certain aspects of the present disclosure provide techniques for multi-carrier on-off keying communications. A method for wireless communications by an apparatus includes receiving a signal comprising multiple carrier frequencies modulated with on-off keying; decoding the signal based at least in part on a delta frequency being associated with a first carrier frequency and a second carrier frequency among the multiple carrier frequencies; and recovering data from the decoded signal.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may participate in sidelink communication using a sidelink slot structure that includes a set of periodic automatic gain control (AGC) candidate transmission time intervals (TTIs) that are common across a wireless network. The UE may monitor for a sidelink message during an interval in accordance with the set of common, periodic AGC TTIs, and the UE may transmit a sidelink feedback message in response to the sidelink message. The UE may transmit the sidelink feedback message over a set of resource blocks (RBs) of the sidelink slot structure if a format of the sidelink feedback message is associated with an uplink control channel format 0. Alternatively, the UE may transmit the sidelink feedback message over more than two symbols of the sidelink slot structure if the format is associated with an uplink control channel format 2.
