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: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

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).
