    Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

    Abstract translation: 本公开的某些方面提供了用于在RACH过程期间发送的上行链路信号的辅助功率控制的技术。 UE可以至少部分地基于UE与主BS之间的通信来确定用于在与辅BS之间的RACH过程期间传送消息的传送功率。 UE可以至少部分地基于所确定的发射功率在RACH过程期间将消息发送到第二BS。

    Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media for a reduced capability (RedCap) user equipment (UE) and supporting cell. The RedCap UE is configured with multiple bandwidth parts (BWPs). A maximum bandwidth of the RedCap UE is lower than a maximum bandwidth of a non-RedCap UEs. The UE receives a cell-defining synchronization signal block (CD-SSB) that defines a shared initial downlink BWP for RedCap UEs and non-RedCap UEs. The UE switches to a separate initial downlink BWP for RedCap UEs. The UE accesses the cell via the separate initial downlink BWP. The UE receives a configuration of an active downlink BWP for RedCap UEs. The UE determines whether to switch from the active downlink BWP to the shared initial BWP or the separate initial downlink BWP to obtain information such as updated system information, system measurements, and uplink configuration information.

    Abstract: This disclosure provides systems, methods, and apparatuses for retransmission of a communication by a relay node based on a failure of a target node to receive the communication. In some aspects, the relay node may determine that the second wireless node has failed to receive the second communication, or an upstream wireless node (such as a distributed unit) may determine that the target node has failed to receive the communication. The relay node may retransmit the communication based on such a determination. In some aspects, the relay node may buffer the communication or information used to generate the communication, and may retransmit the buffered communication. In some aspects, a configuration for the retransmission may be modified based on a capability of the relay node or another concern.

    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless systems, a base station may configure a user equipment (UE) for random access (RACH) message transmission in dedicated RACH resources during, for example, a handover process. The contention-free random access (CFRA) resources may allow the UE to transmit RACH messages at a higher transmission power than contention-based random access (CBRA) resources. The base station may indicate, to the UE, RACH transmission parameters for CFRA that are different than parameters for CBRA. These parameters may include configuration information, frequency division multiplexing information, RACH retransmission parameters, target received power, response window length, etc. The UE may use the indicated RACH transmission parameters to transmit a RACH message to the base station. The base station may respond with a RACH response message, and the base station and UE may synchronize upon completion of the RACH procedure.

    Abstract: Methods, systems, and devices for wireless communications are described that provide for system information (SI) for access and backhaul. An access node (AN) may provide SI to devices within its cell indicating communication procedure configurations. The AN may provide SI to devices that is specific to whether the communication procedure is an access procedure or a backhaul procedure. The AN may transmit a common master information block (MIB) directing the devices within its cell to a search space in order to receive the remaining SI. The search space may be shared between access devices and backhaul devices or alternatively may be separate between access and backhaul devices. The remaining SI may not be shared between access and backhaul devices. The devices may determine different configurations as defined by the SI from the AN for communications procedures based on whether the procedure is an access procedure or a backhaul procedure.
