Abstract: Aspects of the disclosure relate to a base station providing a user equipment (UE) with a sticky uplink beam assignment for one or more uplink signals. The UE may use the sticky uplink beam assignment for transmission of uplink signals until a new sticky uplink beam assignment is received. In some examples, the sticky uplink beam assignment may include an uplink beam identifier (ID) identifying an uplink beam associated with the transmission of an uplink signal. The uplink beam identified by the uplink beam ID may be used by the UE for transmission of the uplink signal and either all subsequent uplink signals (e.g., physical uplink control channel (PUCCH) and/or physical uplink shared channel (PUSCH)) or subsequent uplink signals of particular uplink channel types (e.g., dynamic PUSCH, configured grant (CG), PUCCH, etc.) until a new uplink beam ID is received. Other aspects, features, and examples are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may update a capability to a network entity periodically when the complexity, power, or memory needs of the UE change. The UE may additionally update the capability upon being triggered by a network entity, during a time scheduled by the network entity, upon the expiration of a timer, etc. The capabilities may be or include explicit values for beam switching delay, or an index selecting delay values from a table previously configured to the UE, for example. Additionally, The UE and network entity may support communications according to capability values associated with a time delay between a transmitted reference signal with repetition and the UE being ready for a downlink transmission using a beam selected based on the reference signal. This capability may indicate to the network entity to avoid scheduling downlink messages during the delay.

Abstract: This disclosure provides systems, methods and apparatus for communicating a satellite behavior change. In one aspect, a satellite identifies a satellite behavior change to occur for the satellite of a non-terrestrial network for cellular communications. The apparatus also signals the satellite behavior change to a user equipment serviced by the satellite. In another aspect, a user equipment obtains, from a satellite servicing the user equipment, a signaling of a satellite behavior change to occur for the satellite. The user equipment also adjusts one or more user equipment parameters for cellular communication based on the obtained signaling. The satellite behavior change may include a satellite attitude or a transmit power or coverage area of one or more satellite beams. The user equipment parameters may include satellite or beam selection or reselection to listen to paging information, satellite or beam handover parameters, or transmit power control parameters.

Abstract: An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.

Abstract: Wireless communications systems and methods related to dynamically configuring sounding reference signal (SRS) resources are provided. In some aspects, a base station may measure a SRS transmission transmitted by a user equipment (UE) and receive, using a receive beam selected based on the measuring, a transmission from the UE. In some aspects, a UE may transmit a SRS transmission; and receive, from the BS, a downlink control information (DCI) message including a SRS resource indicator (SRI) for use by the UE in selecting a beam to transmit to the BS. The SRS transmission may be transmitted using a SRS resource and may have a SRS parameter that is indicated in or related to a triggering message, or related to a transmission parameter of a communication between the BS and the UE.

The first and second configurations may be CG of uplink resources for uplink channels. The first and second configurations may indicate SPS resources for downlink channels. The base station may determine the metric based on at least one measurement of signal at the base station or scheduling requirements.

Abstract: A base station determines a temporal filter configuration for a user equipment (UE) and transmits the temporal filter configuration to the UE. The temporal filter configuration indicates whether the UE should apply a temporal filter to channel state information (CSI) measurements to generate CSI values, or identifies which temporal filter to apply. The UE generates CSI values based on the temporal filter configuration and reports the generated CSI values to the base station.
