Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE on a sidelink channel, an indicator of a state of the sidelink channel. Accordingly, the first UE may transmit, to a base station, a request for an additional resource for the sidelink channel, based at least in part on determining that the indicator of the state of the sidelink channel satisfies a condition. For example, the first UE may determine that a modulation and coding scheme (MCS) supported by a current resource for the sidelink channel is outside a range of MCSs granted by the base station. In some aspects, the request may include a negative-acknowledgement (NACK) signal, and the first UE may also transmit a scheduling request for transmitting the indicator of the state of the sidelink channel Numerous other aspects are provided.

Abstract: An apparatus may be configured to determine that a first random access channel (RACH) procedure with a base station is unsuccessful. The apparatus may be further configured to transmit, after determining that the first RACH procedure is unsuccessful, a preamble message for a second RACH procedure with the base station. A second configuration for the second RACH procedure may be different from a first configuration for the first RACH procedure. Another apparatus may be configured to receive a preamble message from a UE for a second RACH procedure having a second configuration different from a first configuration for a first RACH procedure. The other apparatus may be further configured to determine that the first RACH procedure with the UE is unsuccessful.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may transmit an aperiodic channel state information (CSI) request to a UE, wherein the aperiodic CSI request is for sidelink communications; receive, from a base station, an indication of one or more modulation and coding schemes (MCSs) for sidelink communications between the relay UE and the UE based at least in part on transmitting the aperiodic CSI request; receive, from the base station, a communication to be relayed to the UE; and relay the communication to the UE via a sidelink communication that is modulated using an MCS of the one or more MCSs. Numerous other aspects are provided.

Abstract: A data pipeline between a base station and a user equipment (UE) may be formed via a relay UE. In this regard, a base station is configured to send a joint grant to the first UE, the joint grant including a first resource assignment for transmission of data via a first communication link between the base station and the first UE, and a second resource assignment for transmission of data via a second communication link between the first UE and a second UE. The first and second communications link may form a downlink pipeline for transmitting data from the base station to the UE. The first and second communications link may be used to transmit uplink data in parallel from the first UE to the base station.

Abstract: In certain aspects, a method for wireless communication at a user equipment (UE) includes attempting to receive, from a first base station, data via a first communication link, generating a radio link control (RLC) status report indicating a status of the data at the UE, and transmitting, to a second base station, the RLC status report via a second communication link. The UE may be simultaneously connected to the first base station and the second base station using dual connectivity. In one example, the first base station may be configured as a secondary cell group (SCG) and the second base station may be configured as a master cell group (MCG). In one example, the first communication link may be a New Radio (NR) link and the second communication link may be a Long-Term Evolution (LTE) link.

Abstract: The present application relates to user equipment (UE) assisted uplink resource modification. In one implementation, a UE may determine an upcoming absence of uplink data for transmission on an uplink communication channel to a network entity during a period defined by a configured grant, and transmit a message to the network entity to trigger adjustment of at least one resource associated with the configured grant. In another implementation, a network entity may receive a message from a UE representing an upcoming absence of uplink data on an uplink communication channel during a scheduled period defined by a configured grant, and adjust at least one resource associated with the configured grant in response to receiving the message

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a message type for a random access message associated with a two-step random access channel procedure. The message type may be either a first message type or a second message type that is different from the second message type. The message type may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The user equipment may transmit the random access message based at least in part on the determined message type. Numerous other aspects are provided.
