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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a group identifier of the UE. The UE may receive, from the base station, an indication of one or more group identifiers associated with scheduled communications with the base station during a time period. The UE may contend, based at least in part on the group identifier of the UE and the one or more group identifiers received from the base station, for access to a set of autonomous uplink (AUL) resources during the time period. The UE may perform, based at least in part on the contending, an AUL transmission to the base station using the set of autonomous uplink resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, based at least in part on a first downlink reference signal transmitted from a first base station using a downlink reference signal frequency, a first frequency offset associated with transmissions between the UE and the first base station. The UE may determine, based at least in part on a second downlink reference signal transmitted from a second base station using the downlink reference signal frequency, a second frequency offset associated with transmissions between the UE and the second base station. The UE may transmit, to the first base station and the second base station, at least one uplink reference signal using an uplink reference signal frequency that is based at least in part on the first frequency offset and the second frequency offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication regarding a reference signal configuration for a multi-transmit receive point (TRP) communication of the UE, wherein the reference signal configuration relates to at least one serving port and at least one co-scheduled port associated with the multi-TRP communication; and process the multi-TRP communication based at least in part on the indication. Numerous other aspects are provided.

Abstract: New radio (NR) unlicensed (NR-U) operations are discussed with channel occupancy time (COT) multiple downlink-uplink switching opportunities supported by an active channel indication. A network node that initiates a COT for transmissions may identify a within-channel occupancy time (COT) scheduled downlink-uplink switching configuration. After beginning transmissions on the COT, the node receives an active channel indication from one or more additional network nodes. In response to the active channel indication, the node may then perform communications with the node from which the active channel indication is received according to the within-COT scheduled downlink-uplink switching configuration for the current COT on a shared communication channel.

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: Some communication systems enable a user equipment (UE) to have different timelines depending on a category of the UE. One goal of the present method and apparatus is to improve channel utilization by reducing uplink transmission delays (or latency) for a UE in the unlicensed spectrum by not having to rely on a base station to have access to the wireless medium in order to assign a grant to the UE. The UE can transmit on an autonomous uplink (AUL) without having received an uplink grant. When a UE sends AUL traffic during a UE indicated timeline, the base station can indicate a reduced uplink physical uplink shared channel (PUSCH) processing timeline to the UE. The base station may further configure downlink feedback information (DFI) or downlink control information (DCI) monitoring opportunities for the UE. The UE may indicate the preferred AUL processing timeline.

Abstract: A medium reservation framework is disclosed for coexistence of coordinated and uncoordinated wireless networks in licensed spectrum and shared spectrum. The proposed medium reservation framework organically takes into account operating regimes with different numbers of Tx/Rx antennas per node, provides flexibility in trading off medium contention aggressiveness and power saving, leverages the inherent synchronization nature of NR, and covers both coordinated and uncoordinated operation scenarios. Various aspects of the medium reservation framework may be centered on one or more combinations of some basic building blocks, such as an operation grid, synchronization signals, and reservation messages, such as a reservation request signal (RRQ) and one or more a reservation response signals (RRS).

Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a transmitting user equipment (UE) may include receiving, from a base station, a resource configuration of sidelink communications. The transmitting UE may transmit, to a receiving UE, sidelink control information (SCI) via one or more SCI messages, the SCI comprising one or more semi-persistent scheduling indications pertaining to a semi-persistent scheduling configuration for communications from the transmitting UE to the receiving UE. The transmitting UE may monitor for feedback information pertaining to the SCI prior to proceeding with semi-persistent scheduled sidelink transmissions in accordance with the one or more semi-persistent scheduling indications.
