Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain a signal received over a wireless channel, the signal configuring one or more random access parameters for the wireless channel. The UE may obtain a downlink control signal over the wireless channel, wherein the downlink control signal comprises an indication of a trigger and a location of one or more random access occasions for the UE. The UE may output, based at least in part on the downlink control signal, a random access signal for transmission on the wireless channel during at least one of the one or more random access occasions and according to the one or more random access parameters and the location. The UE may establish a connection with a base station based at least in part on the random access signal.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for encoding uplink data for transmission based on control information included in a first uplink grant corresponding to a first set of uplink resources, receiving a second uplink grant associated with a second set of uplink resources, wherein the second uplink grant is associated with the encoded uplink data for transmission, determining a starting time (e.g., a first delay or a second delay) for the second set of uplink resources based at least in part on a timing of the encoding with respect to the second uplink grant, and transmitting uplink data during the second set of uplink resources based on the determined starting time.

Abstract: A base station may generate a channel occupancy time (COT) indication for a user equipment (UE), the COT indication including a bit configuration and a quantized remaining COT duration, and transmit the COT indication to the UE. The quantized remaining COT duration may be a COT floor or a lower quantization level, or to a COT ceiling or a higher quantization level, in which generating the COT indication for the UE may include using a slot format indicator to cancel a radio resource control configured uplink or downlink transmission between a COT duration and the COT ceiling or higher quantization level. UE methods include receiving a COT indication of a bit configuration and a quantized remaining COT duration, and communicating with the base station based on the COT indication. The UE may monitor a physical downlink control channel for uplink and downlink transmissions based on the quantized remaining COT duration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may rate match an uplink transmission around a set of resources reserved by a base station. The base station may indicate a set of reserved resources which overlaps an uplink resource allocation to the UE. The base station may transmit an indicator of the reserved resources, and the UE may identify a location of a clear channel assessment (CCA) gap in a symbol period relative to the reserved resources. By rate matching around the reserved resources and one or more CCA gaps, the UE may transmit uplink information despite the allocated uplink resources colliding with the reserved resources.

Abstract: Methods, systems, and devices for wireless communications in a shared spectrum are described. A user equipment (UE) may transmit, via an autonomous uplink (AUL) communication, one or more transport blocks to a base station. Each transport block may include a plurality of code block groups (CBGs). The base station may provide CBG-level feedback to the UE based at least in part on the AUL communication. For example, a downlink feedback indication (DFI) bit sequence may be partitioned to include a first partition comprising AUL hybrid automatic repeat request (HARQ) feedback information and a second partition comprising contention window (CW) update information (e.g., for a subsequent AUL clear channel assessment). In some cases, the number of bits in the first partition may be based on a number of AUL HARQ processes of the UE and an AUL HARQ process granularity.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a UE or base station, may identify a rate matching resource set for a transmission time interval (TTI) of a shared channel, where the rate matching resource set includes a set of symbols of the TTI allocated for rate matching. In some cases, the wireless device may identify a rate matching configuration for the rate matching resource set based at least in part on a multi-TTI grant for the shared channel, and perform rate matching of a set of data for transmission via the TTI based on the rate matching resource set and the rate matching configuration. In some cases, the wireless device may transmit, or receive, the rate-matched set of data via the one or more TTIs, in accordance with the multi-TTI grant, based on communications with another wireless device.

Abstract: Methods, systems, and devices for multiplexing code block group (CBG) level and transport block (TB) level feedback are described. An example method includes receiving a set of TBs, generating a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and transmitting the bit sequence. Another example method includes transmitting a set of TBs, receiving a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and retransmitting at least one CBG for each TB in the first subset of TBs and the second subset of TBs based at least in part on the bit sequence.
