Abstract: Apparatus, methods, and computer-readable media for facilitating per bandwidth part TCI state or spatial relation are disclosed herein. For example, aspects disclosed herein provide techniques for enabling a UE (e.g., a reduced capability UE) to associate at least one of a TCI state or a spatial relation with respective hopping regions. An example method for wireless communication at a UE includes determining, while communicating using a first frequency range comprising a first set of frequency hops, at least one of a TCI state or a spatial relation for communicating using a second frequency range comprising a second set of frequency hops. The example method also includes communicating, after switching communication from the first frequency range to the second frequency range, using the second frequency range based on the determined at least one of the TCI state or the spatial relation.

Abstract: Apparatus, methods, and computer-readable media for facilitating semi-static TCI configurations are disclosed herein. An example method for wireless communication at a UE includes receiving, from a base station, a first downlink message including a TCI state indicator. The example method also includes initiating a timer after receiving the first downlink message including the TCI state indicator. Additionally, the example method includes receiving, after the timer expires, subsequent downlink messages using the indicated TCI state until a second downlink message including a TCI state change indication is received. An example method for wireless communication at a base station includes transmitting, to a UE, a first downlink message including a TCI state indicator. The example method also includes initiating a timer after transmitting the first downlink message including the TCI state indicator. Additionally, the example method includes transmitting, after the timer expires, subsequent downlink messages based on the indicated TCI state.

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 described herein relate to receiving or determining an indication of multiple component carriers (CCs) configured wireless communications, communicating in a first bandwidth part (BWP) within a first one of the multiple CCs during a first time period, and communicating, based on a hopping pattern, in a second BWP within a second one of the multiple CCs during a second time period.

Abstract: Various aspects relate generally to the beam management procedures in wireless communications systems. Some aspects more specifically relate to the selection of beams for communications to and from a UE and a network entity based on quantized orientation information for a user equipment (UE). In some implementations, a network entity can use the quantized orientation information and a machine learning model to predict a set of beams that may be suitable for communications to and from the UE and the network entity, which may be a subset of the beams that the network entity can generally use for communications to and from the UE and the network entity.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving a first stage of piggyback downlink control information (DCI). The first stage includes scheduling information for a second stage of piggyback DCI. The method also includes receiving the second stage in accordance with the scheduling information. The second stage includes component DCIs. The first and second stages are separately decoded. A method of wireless communication by a base station includes transmitting a first stage of piggyback DCI. The base station also transmits the second stage in accordance with the scheduling information. The second stage includes component DCIs. The first and second stages are separately coded.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). An example method by a user equipment (UE) generally includes receiving a first physical downlink control channel (PDCCH) in a control channel monitoring occasion, the first PDCCH indicating at least one dynamic CORESET; and receiving a second PDCCH within the dynamic CORESET, wherein the second PDCCH is received in accordance with at least one QCL assumption for the at least one dynamic CORESET.

Abstract: Methods and apparatus for efficient transmission of data by half-duplex transceivers in satellite communication systems are provided. Time reference for the return link is skewed or time-lagged relative to the time reference for the forward link to reduce the amount of guard time required to separate return link transmission from forward link reception by the half-duplex transceiver of a user terminal. The guard time is determined based on a maximum differential round-trip propagation delay and transition times of the half-duplexer transceiver to switch between transmit and receive modes. In a satellite communication system in which a large number of active user terminals are present in a beam coverage, random time offsets are applied to spread approximately equal traffic loads across the time offsets.

Abstract: Certain aspects of the present disclosure provide techniques reducing wireless interference in wireless communications networks by, for example, enabling a coexistence period during which transmission over a first wireless communication band is deprioritized and reception over a second wireless communication band, different from the first wireless communication band, is prioritized; and receiving positioning data from a positioning system via the second wireless communication band during the coexistence period.
