Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications device, such as a user equipment (UE) may transmit a capability message indicating a capability of the UE to receive one or more downlink messages during a time slot, and may receive one or more control signalings which schedule a first and a second downlink message during the time slot, indicate a first resource allocation scheduled by a first scheduling configuration, and indicate a second resource allocation scheduled by a second scheduling configuration. The UE may monitor for one or both of the first downlink message or the second downlink message during the time slot based on the one or more control signalings and the capability message. The capability message may indicate a capability of the UE to receive a single downlink message or receive more than one downlink message during the time slot.

Abstract: Resource selection for communication of uplink control information may include determining cyclic shift ramping for resource block (RB) sets. A user equipment UE) may use one or more RB sets for transmitting uplink control information on a shared radio frequency spectrum such as an unlicensed band. In some examples, the UE may transmit uplink control information to a base station (BS) via consecutive RB sets. To this end, the BS may schedule consecutive RB sets for an uplink transmission by the wireless communication device and monitor each of these RB sets for uplink control information.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive a first downlink control message indicating a set of parameters for a scheduling request for the UE. The UE may then receive on a receive beam a second downlink control message, which may be a layer 1 signal, and determine uplink resources for the scheduling request and a transmission configuration indicator state for the scheduling request. The UE may transmit, to the base station, the scheduling request using the uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station transmitting to a user equipment (UE) a partial bandwidth configuration for uplink transmissions, where the partial bandwidth configuration may indicate a channel interlace and a portion of a channel bandwidth, for example, for autonomous uplink (AUL) transmissions. The base station may also transmit to the UE an AUL configuration including a group identifier. The UE may determine a starting offset with respect to an AUL subframe for a partial bandwidth transmission based on the group identifier. In some cases, different UEs may be grouped into groups of UEs allocated non-overlapping resources, and UEs allocated overlapping resources may have different starting offsets to begin transmitting. According to the determined starting offset, the UE may perform the partial bandwidth transmission over the channel interlace and the portion of the channel bandwidth.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a grant scheduling a downlink transmission of a set of configurable downlink transmissions. The downlink transmission may include reference slots corresponding to offset values associated with one or more feedback occasions. The UE may construct a feedback codebook based on a first quantity of slots in the set of configurable downlink transmissions, a second quantity of reference slots in the set of configurable downlink transmissions, and a third quantity of configurable offset values associated with one or more feedback occasions. Based on a size of the feedback codebook, the UE may generate feedback bits for reporting whether the UE successfully received a downlink transmission in corresponding slots. In some examples, the UE may identify a slot with a symbol reserved for an uplink transmission, and skip generating a corresponding feedback bit for the identified slot.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, via an autonomous uplink 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 autonomous uplink communication. In some examples, the base station may provide the CBG-level feedback in one or more downlink feedback information (DFI) packets. In some other examples, the base station may provide the CBG-level feedback via one or more uplink transmission grants. The UE may retransmit one or more CBGs from the autonomous uplink communication based at least in part on the DFI packets or uplink transmission grants.

Abstract: Timing considerations for autonomous uplink (AUL) downlink feedback information (AUL-DFI) is disclosed. With the flexible timeline for new radio (NR) operations, signaling of the processing timeline may be used for the served user equipments (UEs) to properly interpret the acknowledgement information in the AUL-DFI. The UE receives a signal identifying a minimum processing time of the serving base station to process AUL. Using the knowledge of the minimum processing time, the UE determines which of the outstanding AUL transmissions are accurately addressed in the AUL-DFI and which are still pending. Additional signaling to the UE may instruct the UE when to implement any changes to transmission parameters also signaled via the AUL-DFI. Slots prior to the indicated change time will be transmitted using the current parameters, while slots after the indicated time will use the updated parameters from the AUL-DFI.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include receiving, by a user equipment (UE) from a base station, a resource allocation indicator corresponding to a total number of resource elements to allocate for uplink control information within a resource allocation of a shared data channel. The UE may determine anchor resources within the resource allocation, and determine a plurality of transmission parameters for an autonomous uplink transmission based on the total number of resource elements. The UE may transmit, to the base station, the uplink control information within the anchor resources to indicate the plurality of transmission parameters for the autonomous uplink transmission.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for improving transmission opportunity (TxOP) truncation in wireless communication. In some implementations, a transmit opportunity (TxOP) period truncation or whether to update a network allocation vector (NAV) timing based on a message that includes transmitter and receiver information (such as a transmitter address (TA) and a receiver address (RA)) may be determined. For example, a station may receive a contention-free end (CF-End) frame and determine a TxOP period truncation based on comparing a TA and an RA included in the CF-End frame with a TA and an RA included in an earlier received message (e.g., an RTS). Such information may be compared to other TAs or RAs associated with NAV timing values and the NAV timing may be set, reset, updated, or canceled based on the comparison.
