Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device, such as a user equipment (UE), may be configured to communicate with one or more other wireless devices (e.g., another UE) via sidelink communications. The first wireless device may receive an indication of a schedule of resources for sidelink communications to be performed over a communication beam, the schedule indicating a set of resources corresponding to a beam configuration for the sidelink communications with a second wireless device. The first wireless device may communicate with the second wireless device via one or more sidelink channels based on configuring the communication beam using the beam configuration over the set of resources. In some examples, the indication of the schedule of resources may be received in a confirmation of the schedule established by the second wireless device or, in some examples, in a request to establish the schedule.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may belong to a group of UEs that includes at least a second UE and a third UE. The first UE may perform a channel access procedure and, when the channel access procedure is successful, may transmit a first positioning reference signal (PRS) over a sidelink communication link to the second and third UEs. The first UE may transmit the first PRS during a first time interval of a transmission window. Based on receiving the first PRS, the second UE may perform a channel access procedure and may transmit a second PRS to the first UE during a second time interval of the transmission window. The second PRS may be multiplexed (e.g., using frequency division multiplexing (FDM) or code division multiplexing (CDM)) with at least a third PRS transmitted by the third UE.

Abstract: Configurations for configured grant (CG) in new radio unlicensed (NR-U) systems is disclosed. CG configurations may, based on a periodicity, be provided either using a bitmap, shorter periodicity, or resource indicator value (RIV) signaling of start/end symbols, longer periodicity. Such CG configurations configure M sets of time division resource allocations. CG configuration may include common start/end symbols from for all contiguous allocations in one configuration. Common LBT starting points may be defined for all configured slots as indicated through a bitmap. The CG configuration allows for mini- and full slot configurations, in which the mini-slots are configured within the already configured CG slots. Repetition configurations include a type 1 for coverage and a type 2 for faster retransmission and reduced downlink feedback information (DFI) overhead. With multiple UEs, a UE identifier is added to the uplink control information (UCI). UEs may further ramp up power in the absence of DFI.

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: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive at least one bit indicating a particular set of control symbols, of a plurality of sets of control symbols, comprising a downlink control region identify a location of a demodulation reference signal (DMRS), associated with a data channel, based at least in part on the at least one bit indicating the particular set of control symbols comprising the downlink control region; and communicate on the data channel based at least in part on the DMRS. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to a method and apparatus for receiving a medium occupation and a resource block group (RBG) size from a gNB, wherein the radio block group size is based on a bandwidth part (BWP) configuration. In one example, UEs with smaller BWP have finer granularity in RBG size in terms of PRBs, while UEs with larger BWP may have a coarser granularity in RBG size in terms of PRBs. An additional guard band may be used if the gNB reserves some channels such that not all of the BW is occupied. For example, if the gNB reserves the 20 MHz channel, it may perform better by adding additional guard band on each side of the 20 MHz bandwidth to accommodate an adjacent channel leakage-power ratio (ACLR). Another aspect of the present disclosure relates to assigning a UE an interlace with equally spaced PRBs.

Abstract: Methods, apparatuses, and computer-readable storage medium for SL communications are provided. An example method may include transmitting, to a second UE, a SL BWP switching request message requesting a switch from a first BWP to a second BWP. The example method may further include receiving, from the second UE, an SL BWP switching decision message confirming the switch from the first BWP to the second BWP. The example method may further include switching from the first BWP to the second BWP upon receiving the SL BWP switching decision message. The example method may further include transmitting, to the second UE, an SL BWP switching confirmation message confirming the switch from the first BWP to the second BWP. The example method may further include reverting back to the first BWP.

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: Methods, systems, and devices for wireless communications are described. A wireless communications system may support grants for uplink or downlink transmission over multiple transmission time intervals (TTIs). A multi-TTI grant may include a base grant and an extended grant that include separate information and may be transmitted simultaneously (e.g., within the same TTI) or separately. A grant type (e.g., whether a grant is a base grant or an extended grant) or an association between a base grant and an extended grant may be conveyed (e.g., via the multi-TTI grant). A downlink assignment index (DAI) may be included for one or more TTIs subject to the multi-TTI. For instance, DAI may be included for each TTI or for a subset of TTIs.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example, the BS and UE each determine at least one timing value associated with an effective receive time for the PDCCH based upon a reference symbol of the PDSCH.
