Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with other UEs via sidelinks during sidelink communication resources assigned by a base station. However, due to the propagation delay of signals in a wireless communications system, a first UE may receive a sidelink transmission from a second UE in resources delayed with respect to the resources used for transmission. If the delay results in a scheduling conflict (e.g., overlapping resources for reception), the first UE may transmit a timing request to resolve the conflict. In a first example, the base station may receive the request and configure a timing gap based on the request. In a second example, the timing request may indicate to the second UE a sidelink transmission timing adjustment for communicating with the first UE, and the second UE may determine whether to implement this timing adjustment.

The UE may receive a narrowband physical downlink control channel (NPDCCH) that includes an uplink scheduling parameter. The UE may determine an uplink scheduling delay for transmission of a narrowband physical uplink shared channel (NPUSCH) in accordance with time-division duplexing (TDD). The uplink scheduling delay may be based on a sum of a predetermined first number of subframes and a variable second number of subframes.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use information received as part of a two-step random access channel (RACH) procedure to indicate that the two-step RACH procedure has been completed. For example, a UE may perform a two-step RACH procedure that includes the UE transmitting a first message to a base station and, in response, receiving a second message from a base station. The second message may include feedback information the UE uses to signal that the RACH procedure has been completed. In some examples, the feedback information may indicate a physical channel or grant, or both, and a third message may be transmitted by the UE based on the feedback information included in the second message. As such, the third message may serve as an indication that the second message was received, and the UE completed the RACH procedure.

Abstract: When configured, a channel state information reference signal (CSI-RS) can be used to identify new beams. If CSI-RS based monitoring fails to identify new beams, and no other reference signals (RS) are used for beam management, the user equipment cannot identify a new beam. However, instead of using a 4-step random access channel (RACH) procedure for beam recovery request transmission, a modified 2-step contention-based RACH procedure can saves overhead and reduce latency associated with the 4-step procedure.
