Abstract: A method of wireless communications by a user equipment (UE) includes transmitting a request for action for at least one control resource set (CORESET) and associated search space. The action may include configuring, activating, and/or deactivating the at least one CORESET and associated search space. The CORESET may be a dynamic CORESET with a predefined number of search space occasions or a semi-static CORESET. The method also includes communicating in accordance with the request. The request is transmitted using at least one of an uplink radio resource control (RRC) message, a physical uplink control channel (PUCCH), a sounding reference signal (SRS), a random access channel (RACH), or a physical uplink shared channel (PUSCH). The UE may switch, in connection with the request, to a bandwidth part (BWP) configured for the UE.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating timing resolution limitations due to synchronization signal blocks (SSBs) with low subcarrier spacing (SCS). An example method by a user equipment (UE) generally includes detecting a SSB; determining a start time of a control resource set (CORESET) associated with the detected SSB, wherein the start time of the CORESET is aligned with a boundary of a symbol having a larger cyclic prefix (CP) than one or more other symbols in a same half-subframe; and monitoring the CORESET for a physical downlink control channel (PDCCH) transmission.

Abstract: A base station (110) determines a resource allocation for a piggyback DCI (505), configures a scheduling DCI that schedules a PDSCH transmission with an indication of the resource allocation for the piggyback DCI (510), and transmits the scheduling DCI (515) to a user equipment (120). The user equipment (120) receives the scheduling DCI (515), determines the resource allocation for the piggyback DCI (520), receives the PDSCH transmission that includes the piggyback DCI (525), and detects the PDSCH and the piggyback DCI (530).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of a beam switching capability of the UE as a multiple of a physical layer timing unit for a wireless network in which the UE is located; and receive one or more scheduling grants that are based at least in part on the beam switching capability of the UE. Numerous other aspects are provided.

Abstract: Disclosed are techniques for positioning. A receiver receives complementary timing information associated with the positioning reference signals (PRS) of a repetition of a PRS sequence. The complementary timing information distinguishes a repetition of a PRS sequence from remaining repetitions of the PRS sequence. Based on the complementary timing information associated with different PRS from different non-terrestrial vehicles indicating that the PRS were transmitted during the same radio frame, the receiver can determine an observed time difference of arrival (OTDOA) between the PRS received from the respective non-terrestrial vehicles.

Abstract: Satellites in a non-terrestrial network may provide positioning reference signals (PRS) to user equipment (UE), with which the UE may determine its position using propagation delay difference measurements, such as Time Difference of Arrival (TDOA) measurement. Due to the large distances between satellites and the UE, the propagation delay differences in the PRS received from satellites may exceed half a radio frame, resulting in a frame level timing ambiguity in the differential measurements. The satellites transmit secondary PRS, along with primary PRS, that include timing information to resolve frame level timing ambiguity of the primary PRS. The positioning occasions in the secondary PRS, for example, may be aligned with corresponding positioning occasions primary PRS within each radio frame, and are transmitted with a periodicity that is an integer multiple (greater than 1) of that of the primary PRS to resolve the frame level timing ambiguity of the primary PRS.

Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

Abstract: A method and apparatus for operating a satellite system including different satellites that may belong to different types of satellite constellations. In some implementations, the satellite system may include a LEO satellite constellation and one or more non-LEO satellite constellations that can be used to increase the forward link capacity of the LEO satellite constellation, for example, by allowing an LEO satellite to offload at least some of its forward link traffic to one of the non-LEO satellites. The user terminals can dynamically switch forward link communications between a LEO satellite and a non-LEO satellite while maintaining a return link connection with the LEO satellite.
