Abstract: A UE may select a first beam for communication with a base station. The UE may attempt, through the selected first beam, at least one RACH procedure with the base station. The UE may determine that the at least one RACH procedure failed with the base station. The UE may send, after a successful RACH procedure with the base station, information indicating that the at least one RACH procedure failed. In an aspect, the UE may select a new beam for communication with the base station after the determination that the at least one RACH procedure failed, and at least a portion of the successful RACH procedure may be performed through the selected new beam.

Abstract: Beam specific power ramping counters may be used to adjust uplink transmit power. For example, a user equipment (UE) may use counters for beam specific power control of Random Access Channel (RACH) Message1 transmissions. A UE may transmit a RACH message1 on a beam specific resource and increment a counter corresponding to a gNB downlink beam. Power adjustments may be made on subsequent re-transmissions of the RACH message1 according to a power control policy. The power control policy may call for applying a power ramping function based on the value(s) of one or more of the counters.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be communicating with a base station via beamformed transmissions on an active beam. The UE may receive from the base station refined reference signals (RRSs) that include an active beam RRS corresponding to the active beam. The UE may identify that the active beam RRS corresponds to the active beam and perform a beam state measurement on the active beam RRS. The UE may refine the active beam based at least in part on the beam state information of the active beam RRS.

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: In millimeter wave systems, user equipment may not be able to receive RACH parameters through a PDCCH when the information is transmitted with an omni-directional beam. In an aspect of the disclosure, an apparatus, such as a base station, may determine the RACH parameters and transmit a subset of the RACH parameters via a PBCH. The user equipment may receive the RACH parameter subset and initiate a RACH procedure.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access (RACH) procedure based on a selected synchronization signal block (SSB). During this RACH procedure, a base station may transmit physical downlink control channel (PDCCH) messages for UE RACH message handling. To receive PDCCH signaling for RACH Messages 2, 3, or 4 (Msg 2/3/4), the UE may identify a set of time resources used by the base station for transmitting SSBs that are not quasi-co-located (QCL) with the selected SSB. The UE may identify a Msg 2/3/4 search space that does not overlap with this identified set of resources, and may monitor this identified search space. The search space may correspond to a modified remaining minimum system information (RMSI) search space indicated by the base station, or a valid RMSI search space not indicated by the base station.

Abstract: A transmit beamforming gain and a receive beamforming gain may be used when adjusting an uplink transmit power. For example, a user equipment (UE) may receive downlink communications from a base station on a receive beam having a beamforming gain that is different from a beamforming gain for an uplink transmit beam. The UE may adjust an uplink transmit power (e.g., for transmitting a random access channel (RACH)) based on a difference in the beamforming gains. For example, a parameter representing the difference in the beamforming gains, in addition to a maximum allowed transmit power, a target preamble received power, and an estimated path loss, may be used when determining an adjusted uplink transmit power for a RACH transmission. The adjustment may result in a higher or lower transmit power depending on the difference in the receive beamforming gain and the transmit beamforming gain.

Abstract: One apparatus may be configured to detect a set of beams from a base station. The apparatus may be further configured to select a beam of the set of beams. The apparatus may be further configured to determine at least one resource based on the selected beam. The apparatus may be further configured to transmit, on the at least one determined resource, a beam adjustment request to the base station. The request may indicate an index associated with the selected beam. Another apparatus may be configured to transmit a first set of beams. The other apparatus may be further configured to receive a beam adjustment request on at least one resource. The other apparatus may be further configured to determine a beam index of a beam in the first set of beams based on the request and the at least one resource.

Abstract: Methods, systems, and devices for wireless communications are described that provide for partitioning of time-frequency resources for access and backhaul links separately. A centralized scheduler in a centralized system or a set of access nodes (ANs) in a distributed system may allocate a portion of a set of resources for a given link type (e.g., access or backhaul). In some cases, multiple ANs may exchange reports or measurements to determine the resources to allocate to a given link type. The allocated resources may be repurposed for use by a different link type (e.g., access resources may be repurposed and used for backhaul resources) in order to account for varying traffic conditions.
