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: Aspects of the present disclosure provide for beam management in wireless communication systems. In some examples, beam angle information (e.g., angles of arrival/departure) may be utilized to select one or more serving downlink beams for communication between a scheduling entity and a scheduled entity. The beam angle information may further be utilized to facilitate additional operations within a backhaul network, such as wireless node locating, obstacle locating, system mapping within the network topology, beam determination and beam sweeping configuration, and mobility management among wireless nodes of a backhaul network. In other examples, aperiodic uplink beam measurements may be triggered based on downlink beam measurement reports and/or in response to a request from a scheduled entity. The scheduling entity may then jointly select uplink and downlink beams based on both the received downlink beam measurement report and uplink beam measurements.

Abstract: The present disclosure provides for inter-cell interference randomization between two or more cells. For example, a network entity may determine a cell identifier associated with the network entity and perform at least one of an interleaving, rate-matching, or resource element mapping on at least one codeword based on the cell identifier. The network entity may further communicate with a user equipment (UE) in accordance with performing at least one of the interleaving, rate-matching, or resource element mapping on the at least one codeword. In another example, a UE may receive a message from a network entity on a communication channel and identify a cell identifier associated with the network entity. The UE may further perform at least one of a de-interleaving, de-rate-matching, or resource element de-mapping on the message based on the cell identifier.

Abstract: Methods and apparatus for early determination of an operation mode in a Narrowband Internet of Things (NB-IoT) system are provided. A User Equipment (UE) determines a mode of operation of a NB-IoT network before decoding a broadcast channel which indicates the mode of operation, based on at least one synchronization signal received at the UE, wherein the mode of operation indicates what bandwidth resources are used in the network. The UE processes signals based on the determined mode of operation.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for generating and communicating reference signals. Certain aspects provide a method for communicating reference signals. The method includes selecting a reference sequence of a plurality of reference sequences to transmit in a cell in a synchronization signal block (SSB) based at least on a logical value, wherein the logical value is determined based on a SSB index indicating a location of the SSB within a set of resources of a plurality of sets of resources and at least one of a cell ID of the cell, a set index indicating a location of the set of resources within the plurality of sets of resources, or a second value based on system information corresponding to the cell; and transmitting the selected reference sequence in the SSB.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether to perform a beam pair refinement procedure with regard to the UE and a base station; and/or transmit, to the base station, information regarding whether to perform the beam pair refinement procedure. In some aspects, a base station may receive, from a UE, information regarding a beam pair refinement procedure with regard to the UE; and/or perform the beam pair refinement procedure based at least in part on the information. Numerous other aspects are provided.
