Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain, via broadcast signaling or UE-specific signaling, an indication of an uplink communications configuration for one or more uplink wireless communications that span a set of one or more transmission time intervals (TTIs). The indication may be based on one or more types of the one or more uplink wireless communications. The UE may determine a duration of time for which an uplink pre-compensation is to be applied to the one or more uplink wireless communications. The duration of time may be based on one or more parameters of the uplink communications configuration. The UE may output the one or more uplink wireless communications within the duration of time with the uplink pre-compensation applied.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may receive, from a network node, a paging message indicating information for communication between the network node and the UE. In some examples, the UE may receive, from a network node, a downlink alert message indicating a paging message for subsequent transmission to the UE. The UE may identify a delay based on receiving the paging message or the downlink alert message, a measurement of a communication link satisfying a threshold, or any combination thereof. The UE may establish an uplink connection with the network node based at least in part on an expiration of the delay. The UE may communicate the information using the uplink connection.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may transmit, to a base station of a non-terrestrial network, a random access request message associated with a random access procedure using a transport block size (TBS) and a power control specified for the random access request message (e.g., a payload of the random access request message) for the random access procedure. The random access request message including a random access preamble and a random access payload carrying a buffer status report (BSR) or uplink data, or both. The UE may then monitor a response window based at least in part on transmitting the random access request message. The UE may receive, from the base station of the non-terrestrial network, a response message of the random access procedure during the response window.

Abstract: Methods, systems, and devices for wireless communications are described. A network may be configured to provide a beam measurement configuration to a UE that indicates durations for monitoring transmission beams, and tuning a component of the UE between the monitoring. The durations may include a first portion that a UE may use for a tuning operation and a second portion that the UE may use to monitor for or measure a respective reference signal. In various examples, the indicated durations may include a third portion that the UE may use for another tuning operation, or the durations may overlap with one another during an overlap duration that the UE may use for another tuning operation. During the indicated durations, the network may refrain from transmitting other downlink data or control information for the UE, and the UE may refrain from monitoring for such other downlink data or control information.

Abstract: Methods, systems, and devices for wireless communications are described. Various techniques for bandwidth part activation and signaling are described. Control messaging may be used to indicate a mapping of beams and bandwidth part to respective indices, such as a bandwidth part identifier or a transmission configuration indicator (TCI) state codepoint. Further control messaging may specify one of these indices, and a user equipment (UE) may communicate with a network entity, such as a satellite or base station using a bandwidth part in a beam specified in the control messaging.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a multicast service available for subscription by the UE or to which the UE is already subscribed. The UE may transmit a message, to a network node, that may include UE assistance information (UAI) indicating at least one of a UE capability to process multicast transmissions or a feedback scheme preference for reporting feedback for the multicast transmissions. The UAI may also include at least one of a multicast carrier preference, band or carrier measurement report, a multicast priority indication, or a measurement and reporting scheme preference for the multicast transmissions. The network node may receive the UAI and determine one or more parameters for multicast communications with the UE based on the UAI. The UE may receive the multicast transmissions from the network node in accordance with the UAI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of system information blocks (SIBs) common to a set of cells of a non-terrestrial network (NTN), the set of SIBs indicating one or more parameters common to the set of cells for communications with the set of cells. The UE may receive a first SIB associated with a first cell of the set of cells of the NTN, where the first SIB includes cell-specific information indicating a first set of cell-specific parameters for communications with the first cell. The UE may then communicate with the first cell using the first set of cell-specific parameters associated with the cell-specific information of the first cell and at least a first sub-set of parameters of the one or more parameters that are common to the set of cells.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit buffer status information using configured periodic uplink resources. For example, a base station may configure dedicated periodic uplink resources, periodic random access resources, or periodic uplink grants to enable the UE to transmit the buffer status information. In some cases, the periodic random access resources may enable the UE to transmit a first message of a four-step or two-step random access procedure to indicate the buffer status information. Additionally or alternatively, the base station may configure a type of scheduling request for the UE to transmit that can indicate whether a buffer size falls within a range, where the base station then can more accurately allocate uplink resources in an uplink grant for the UE to transmit the uplink data based on receiving this type of scheduling request.

Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, otherwise known as a user equipment (UE) may transmit a random access message (e.g., a message 3) associated with a random access procedure. A hybrid automatic repeat request (HARQ) feedback may be disabled for the random access procedure. The UE may initiate a contention resolution window associated with the random access procedure for a first downlink data channel transmission of a set of downlink data channel transmissions associated with the random access procedure. The UE may receive, during the contention resolution window, the first downlink data channel transmission carrying a contention resolution medium access control-control element (MAC-CE). The UE may transmit acknowledgment information for the first downlink data channel transmission carrying the contention resolution MAC-CE based on an indication to enable the HARQ feedback.
