Abstract: Methods, systems, and devices for wireless communications are described. A satellite may determine one or more sets set of resources for conveying reference signals to a user terminal. In one example, the satellite may determine a set of resources that includes multiple resource groups each associated with a respective frequency range. In another example, the satellite may determine multiples sets of resources and each set of resources may include resources within respective frequency range. Upon determining the set(s) of resources, the satellite may transmit an indication of the set(s) of resources to a user terminal.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a user equipment (UE) to indicate both configured grant (CG) skipping and CG group switching information in a single uplink control message. For example, a network entity may indicate one or more behaviors (e.g., a first behavior for CG skipping, a second behavior for CG group switching from a first CG group to a second CG group, etc.). The UE may transmit, to the network entity, a single uplink control message including a single indicator which can refer to the first behavior, or the second behavior (e.g., and may refer to switching from any CG group to another CG group).

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may add a first extension before modulated symbols of a communication, the first extension including data from an end portion of the modulated symbols. The transmitting device may add a second extension after the modulated symbols, the second extension including data from a beginning portion of the modulated symbols. The transmitting device may apply a first weighting function that overlaps the first extension and the beginning portion of the modulated symbols. The transmitting device may apply a second weighting function that overlaps the end portion of the modulated symbols and the second extension. The transmitting device may add one or more of a header before the first extension or a tail after the second extension. The transmitting device may transmit the communication. Numerous other aspects are described.

Abstract: Systems and techniques are provided for wireless communications. For example, a first network node (e.g., a user equipment (UE) or other network node) may receive a reference signal and cause uplink information to be transmitted to a second network node (e.g., a base station, such as a gNodeB (gNB)). The uplink information is indicative of first measurement information associated with the reference signal and feedback information associated with a transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a flag is enabled or is disabled, the flag indicating whether channel state information (CSI) associated with a secondary discontinuous reception (DRX) group is permitted to be transmitted outside of an active time associated with a primary DRX group. The UE may selectively transmit the CSI associated with the secondary DRX group in an uplink communication associated with the primary DRX group based at least in part on whether the flag is enabled or is disabled. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for time division multiplexing (TDMing) user equipment (UE) data using guard interval (GI)-based waveforms. An example method generally includes communicating with a device using a frame format, the frame format comprising a first symbol, a second symbol, and a third symbol, wherein: the first symbol comprises a first data portion for a first UE and a first GI corresponding to the first UE; the third symbol comprises a second data portion for a second UE and a second GI corresponding to the second UE, wherein the third symbol is later in time than the first symbol; and the second symbol comprises a gap or a reference signal (RS), a third GI corresponding to the first UE, and a fourth GI corresponding to the second UE, wherein the second symbol is between the first and third symbol in time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of transmission configuration indicator (TCI) states and a TCI-field codepoint mapping, wherein an active subset of the set of TCI states is active in accordance with a default configuration. The UE may communicate, based at least in part on the TCI-field codepoint mapping and the default configuration, using a default active TCI state of the active subset of the set of TCI states.
