Abstract: Methods, systems, and devices for wireless communications are described. A base station may dynamically cancel and reschedule configured transmission occasions for communicating with a user equipment (UE). The transmission occasions may be configured according to a semi-persistent scheduling (SPS) configuration (e.g., for downlink transmissions) or a configured grant (CG) configuration (e.g., for uplink transmissions). The base station may transmit a dynamic grant to the UE that indicates a cancellation of a transmission occasion and schedules a dynamic transmission occasion for communicating data scheduled for transmission at the canceled transmission occasion. In some examples, the cancellation in the grant may be explicit or implicit.

Abstract: Disclosed are techniques for wireless sensing. In an aspect, a user equipment (UE) measures at least a line-of-sight (LOS) path and a non-line-of-sight (NLOS) path of a first downlink positioning reference signal (DL-PRS) from a first transmission-reception point (TRP), measures at least an LOS path and an NLOS path of a second DL-PRS from a second TRP, measures at least an LOS path and an NLOS path of a third DL-PRS from a third TRP, and enables a location of a non-participating target object to be determined based, at least in part, on reference signal time difference (RSTD) measurements between a time of arrival (ToA) of the LOS path of the first DL-PRS and the ToAs of the NLOS paths of the first, second, and third DL-PRS. In an aspect, the non-participating target object does not participate in determining its own location.

Abstract: Aspects relate to obtaining, at a first scheduled entity, a first priority ranking of first uplink (UL) data scheduled for transmission to a scheduling entity and a first data scheduled for transmission to a second scheduled data, as well as a second priority ranking of second data scheduled for transmission to a third and fourth scheduled entity, respectively. The scheduling uses at least a portion of a sidelink resource reserved for sidelink communication for the transmissions. The scheduling of the transmissions using at least the portion of the sidelink resource are based on the first priority ranking and the second priority ranking. Various transmission cancellation and reception preemptions are transmitted from transmitting scheduled entities to other transmitting or receiving scheduled entities, respectively. Such cancellations and preemptions are based on the priority rankings, prediction of data transmission collisions and prediction of interference at receiving entities.

Abstract: Techniques for alternative semi-persistent scheduling (SPS) parameter implementation in association with preemption of use of resources corresponding to other SPS parameters are described. Wireless devices may be implicitly informed with respect to implementing alternative resources corresponding to one or more alternative SPS parameters when use of resources corresponding to first SPS parameters is preempted. A disruption indication (DI), such as used to indicate preemption of downlink transmission on downlink SPS allocated resources and/or a cancellation indication of uplink transmission on uplink SPS allocated resources, may be used to inform (e.g., implicitly) one or more wireless devices to employ alternative resources corresponding to alternative SPS parameters available to the wireless devices. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive, in a first paging occasion, paging information that identifies a data transmission in a second paging occasion subsequent to the first paging occasion; and receive the data transmission during the second paging occasion. Numerous other aspects are provided.

Abstract: Bits for acknowledgement (ACK) and/or negative acknowledgement (NAK) may be allocated based on whether a special subframe configuration in a TDD configuration permits downlink transmission. For carrier aggregation, ACK/NAK bits may be allocated only to special subframes in component carriers (CCs) which permit downlink transmission. Also, for example, ACK/NAK bits may be allocated to all CC special subframes if a single CC is configured to allow downlink transmission on one of its special subframes. ACK/NAK bits may also be allocated to all special subframes.

Abstract: A method and apparatus for wireless communications are described. The method and apparatus may include transmitting at least one frame that includes a first acquisition interval associated with a first operator and one or more first transmission opportunities having a guarantee interval for the first operator, and a second acquisition interval associated with a second operator different from the first operator and one or more second transmission opportunities having a guarantee interval for the second operator, the first acquisition interval and the one or more first transmission opportunities nonoverlapping with the second acquisition interval and the one or more second transmission opportunities.

Abstract: Certain aspects of the present disclosure provide techniques for identifying, from a resource pool allocated for sidelink communications between UEs, a first number of resources for transmissions from the first UE to a second UE based on a set of one or more parameters shared between the first UE and the second UE and identifying, from the resource pool, a second number of resources for transmissions from the second UE to the first UE based on the shared set of one or more parameters. The first UE may communicate with the second UE using the first and the second number of resources and avoid using the remaining available resources for power saving. For example, the first UE and the second UE may avoid sidelink communications on time slots on which no subchannels belong to either the first subset or second number of the resources.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity configures a sidelink anchor group with sidelink anchor(s), to which respective sidelink PRS pre-configuration(s) are sent. A UE transmits a request to schedule an on-demand sidelink PRS position estimation session of the UE. The position estimation entity provides the UE with assistance data associated with the sidelink anchor group for the on-demand sidelink PRS position estimation session. The UE sends the sidelink anchor group a sidelink PRS trigger to perform a sidelink PRS exchange with some or all of the sidelink anchor group in accordance with the respective sidelink PRS pre-configuration(s).

Abstract: Disclosed are systems and techniques for performing sidelink communications. For instance, a first client device can determine a first transmit power parameter for transmitting sidelink communications. The first transmit power parameter can either be received from a base station associated with the first client device or it can be a default parameter based on the first client device not being associated with a base station. The first client device can transmit, to a second client device, a first sidelink transmission having a first power level corresponding to the first transmit power parameter. The first client device can receive, from the second client device, a first sidelink reception having a second power level corresponding to a second transmit power parameter.
