Abstract: Aspects relate to mechanisms for improved uplink and sidelink coverages. A first network entity determines one or more channel state feedback (CSF) parameters of one or more beams associated with the first network entity, selects one or more beam coefficients based on the one or more CSF parameters, and transmits the one or more beam coefficients to at least a second network entity. The second network entity selects one or more beams for beaming forming based on the one or more beam coefficients, determines one or more CSF parameters of the one or more beams associated with the second network entity, and transmits the one or more CSF parameters of the one or more beams associated with the second network entity to the first network entity. The first network entity selects one or more new beam coefficients based on the one or more CSF parameters from the second network entity.

Abstract: A UE may be configured to obtain at least one configuration of a set of RPs from a network node, the set of RPs being associated with grant-free NOMA for sidelink communication, and transmit a sidelink transmission via a sidelink channel to at least one other UE in the set of RPs associated with the grant-free NOMA based on the at least one configuration of the set of RPs. The at least one configuration of a set of RPs may include at least one of a power configuration, a DMRS configuration, or a set of FD-OCC associated with a PSCCH, and an oversampling factor is applied to the set of FD-OCC.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may configure uplink resources within a slot to enable a user equipment (UE) to transmit an acknowledgment (ACK) feedback message for multiple downlink semi-persistent scheduling (SPS) configurations. For example, the base station may transmit an additional configuration to the UE that indicates uplink resources that the UE can use to transmit acknowledgment feedbacks for multiple downlink messages received according to the SPS configurations, where the UE determines which uplink resource to use based on a number of acknowledgment information bits to be transmitted for the acknowledgment feedback message. For example, if the number of acknowledgment information bits is below a threshold value, the UE may use a first uplink resource configured by the base station. Alternatively, if the number of acknowledgment information bits is above the threshold value, the UE may use a second uplink resource.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). In one aspect, a method includes determining that (1) a first scheduled sidelink transmission to a first receiving UE using a first set of component carriers and (2) a second scheduled sidelink transmission to a second receiving UE using a second set of component carriers will overlap in a time domain; determining that the first scheduled sidelink transmission has a first transmission time length and the second scheduled sidelink transmission has a second transmission time length, wherein the second transmission time length is shorter than the first transmission time length; segmenting the first scheduled sidelink transmission into a plurality of first sidelink transmission segments; and sending, to the first receiving UE, an indication of the plurality of first sidelink transmission segments.

Abstract: Position determination for a target user equipment (UE) uses a single base station and a plurality of sidelink UEs with known locations. The base station sends a reference signal to the target UE and sidelink UEs, and the target UE sends sidelink signals to each sidelink UEs. A range-sum for the range between the target UE and sidelink UE and the range between the sidelink UE and the base station can be determined for each sidelink UE, based on the time differences between the reception and transmissions of the reference signals measured by the target UE, and the time difference between reception of the reference signals measured by the sidelink UE. A differential in the range-sums can be determined and used to determine the position of the target UE.

Abstract: Certain aspects of the present disclosure relate to uplink preemption in certain systems, such as new radio (NR) systems, supporting carrier aggregation (CA) and/or multi-connectivity modes. A method for wireless communication, that can be performed by a user equipment (UE), generally includes receiving a resource assignment scheduling the UE for uplink transmission. The UE receives an indication to preempt uplink transmission on a portion of the assigned resources and determines whether to transmit on the remaining assigned resources. A method that can be performed by a base station (BS) generally includes receiving an indication from one or more UEs indicating, for each of a plurality of band combinations, a capability of the UE to transmit on a band when transmission on another band in the band combination is preempted and scheduling the one or more UEs for uplink transmission based on the indication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine one or more sidelink discontinuous reception (DRX) parameters for a configured sidelink DRX cycle. The sidelink DRX parameters may be selected by the UE or may be indicated by a base station. In some cases, the UE may transmit an indication of the sidelink DRX parameters to another UE (e.g., via a sidelink communication link). A UE may discontinuously monitor for transmissions over the sidelink communication link in accordance with the sidelink DRX parameters.
