Abstract: A method for wireless communication at a first network entity and related apparatus are provided. In the method, the first network entity communicates, with a second network entity, information indicative of a guard interval length. The information indicative of the guard interval length is based on transmission information. The first network entity further communicates, with the second network entity, a transmission including one or more symbols. Each symbol of the one or more symbols includes a particular guard interval based on the information indicative of the guard interval length. The method enables the GI length to be flexibly configured depending on various waveforms or channel parameters and characteristics of the transmission. The method enables transmission resources to be fully utilized according to actual operating conditions. Thus, it improves the efficiency and flexibility of wireless communication.

Abstract: Certain aspects of the present disclosure provide techniques for dynamically indicating or determining channel occupancy time (COT) for uplink transmissions. For example, a user equipment (UE) may determine whether a scheduled uplink transmission is based on CE-initiated COT or sharing a network initiated COT (both generally referred to as “COT types”) based on content in the scheduling downlink control information (DCI) or a rule applied for a configured uplink transmission. The present disclosure provides techniques for determining the COT types by using corresponding fields in the DCI when applicable, or when the corresponding fields are absent, by introducing rules configuring the uplink transmission.

Abstract: A method of wireless communication performed by a user equipment (UE) includes receiving, from a base station (BS) in a first fixed frame period (FFP), downlink communication information (DCI), where the DCI indicates a scheduled DL communication in a second FFP subsequent to the first FFP. The method also includes monitoring for a downlink (DL) signal in the second FFP. The method also includes transmitting, based on the monitoring for the DL signal, an acknowledgement/non-acknowledgement (ACK/NACK) indicating whether the scheduled DL communication was detected.

Abstract: Certain aspects of the present disclosure provide techniques for determining a relay capability configuration for using a control signal to schedule a physical sidelink shared channel (PSSCH) that carries information to organize sidelink connections. The control signal allows user equipments (UEs) to organize a sidelink network absent base station configurations or vendor configurations. For example, the control signal may schedule a discovery signal (DS) associated with a sidelink synchronization signal block (S-SSB). The control signal may be referred to as DS-physical sidelink control channel (DS-PSCCH), different from a normal PSCCH. The DS-PSCCH may have distinct structure and content to allow UEs to organize sidelink networks.

Abstract: This disclosure provides systems, methods and apparatuses for indicating sidelink processes for sidelink feedback. A second user equipment (UE) may request hybrid automatic repeat request (HARQ) responses from a first UE for a particular set of sidelink processes over a physical sidelink feedback channel. To indicate multiple sidelink processes, the second UE may indicate, in sidelink control information, a window of sidelink processes. The window may be a sliding window that starts with a starting sidelink process and extends through other sidelink processes. The second UE may transmit data for the sidelink processes in the sliding window and receive feedback for the indicated sidelink processes. In some aspects, the first UE may select, in coordination with the second UE, the sidelink processes for which feedback is to be provided.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured with one or more semi-persistent scheduling (SPS) configurations. A base station may transmit a first downlink control information (DCI) transmission to the UE that activates an SPS configuration, and the first DCI may indicate a non-numeric feedback timeline for reporting associated acknowledgment feedback. The base station may transmit a subsequent second DCI transmission that provides feedback resources, and the UE may receive the second DCI and identify timing and resources for SPS acknowledgment feedback based on the second DCI. The UE may then transmit the acknowledgment feedback for one or more SPS transmissions in the feedback resources that are indicated by the second DCI transmission.
