Abstract: Certain aspects of the present disclosure provide techniques for including physical layer RSSI in CSI reporting. In some cases, a method for wireless communications by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration that specifies physical layer received signal strength indicator (RSSI) measurement as a report quantity, performing physical layer RSSI measurement, and reporting the RSSI to a network entity in accordance with the CSI reporting configuration.

Abstract: Aspects directed towards communications for random access procedures are disclosed. In one example, a first beam and a second beam may be available for communications between a scheduled entity and a scheduling entity. The scheduling entity may send, and the scheduled entity may receive, a message 1 transmission for a random access procedure on the first beam. The scheduled entity may open a random access response (RAR) window to monitor for a message 2 transmission according to a predetermined sequence designating whether to monitor the first beam, the second beam, or some combination thereof. The scheduling entity may send, and the scheduled entity may receive, the message 2 transmission on the first beam or the second beam as designated by the predetermined sequence. Other aspects, embodiments, and features are also included.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, related to long term sensing based inter-operator coexistence techniques for unlicensed high bands providing a measurement framework and candidate measurements, along with channel selection, per-beam channel deselection, and dynamic frequency selection. In one aspect, a network entity may determine that a non-coordinating node satisfies a communication presence threshold based on the at least one long term sensing measurement, and transmitting, to a user equipment (UE), an indication of a remedial action, or adjusting the communication channel based on the determination. In another aspect, a UE may obtain at least one long term sensing measurement, and transmit a long term sensing report including the at least one long term sensing measurement.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving first downlink information, failing to decode a first portion of the first downlink information, transmitting, to a base station (BS), a first response including a negative acknowledgement (NACK) indicating a first decoding failure associated with the first portion of the first downlink information, receiving second downlink information, failing to decode a first portion of the second downlink information, detecting a hybrid automatic repeat request (HARQ) buffer unavailability, determining to discard NACK information associated with the NACK, resetting at least a portion of a HARQ buffer, in response to detecting the HARQ buffer unavailability, by discarding NACK information associated with the NACK, generating a reset NACK indicating the HARQ buffer reset and indicating the NACK information being discarded, and transmitting a second response including the reset NACK to the BS.

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: 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.
