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: Methods, systems, and devices for wireless communication are described. Discontinuous reception (DRX) operation may be configured differently on enhanced component carriers (eCCs) than on other component carriers, including a primary cell (PCell). In some cases, a user equipment (UE) may be configured with several different eCC DRX modes. An eCC DRX configuration may, for example, be coordinated with downlink (DL) transmission time interval (TTI) scheduling so each DRX ON duration may correspond to a DL burst duration of the corresponding eCC. The eCC DRX ON durations may also be scheduled according to hybrid automatic repeat request (HARQ) process scheduling. In some examples, eCC DRX ON durations may be based on listen-before-talk (LBT) procedures. In some cases, eCC DRX ON durations may be configured to contain an uplink (UL) burst to enable channel state information (CSI) reporting. The eCC DRX may also be configured to minimize interruption of the PCell.

Abstract: A UE may establish a communications link with a base station. The UE may determine at least two radio network temporary identifiers (RNTIs) associated with the communications link, wherein each of the at least two RNTIs is associated with a respective relay device of a plurality of relay devices. The UE may receive, from a first relay device of the plurality of relay devices, at least one first stream associated with a first RNTI of the at least two RNTIs, wherein the at least one first stream carries data or control information associated with the communications link. The UE may receive, from a second relay device of the plurality of relay devices, at least one second stream associated with a second RNTI of the at least two RNTIs, wherein the at least one second stream carries data or control information associated with the communications link.

Abstract: Certain aspects of the present disclosure provide techniques for reuse one channel access for new radio communications in unlicensed spectrum. A method that may be performed by a first base station (BS) includes occupying a bandwidth, based on a category 4 (CAT4) listen before talk (LBT) procedure on the bandwidth, wherein the CAT4 LBT procedure is based on a first contention window (CW); arranging a category 2 (CAT2) LBT occasion for the bandwidth during a channel occupancy time (COT) for the bandwidth; and receiving an indication that at least a second BS has occupied the bandwidth during the CAT2 LBT occasion.

Abstract: Certain aspects of the present disclosure provide techniques for new radio (NR) communications in narrowband regions of unlicensed spectrum. A method that may be performed by a user equipment (UE) includes determining, using an energy detector (ED), that received energy in a first bandwidth (BW) is lower than a threshold; and transmitting, in response to determining that received energy in the first BW is lower than the threshold, a first uplink (UL) transmission to a base station (BS) in a second BW smaller than the first BW and contained within the first BW.
