Abstract: A UE may receive, from a base station, a message requesting BSI . The UE may determine a number N of BSI reports to send to the base station, and each BSI report may indicate a beam index corresponding to a beam and a received power associated with the beam. The UE may send, to the base station, N BSI reports based on the message requesting BSI. The UE may receive, from the base station, a set of signals through a set of beams, and determine the received power for each signal of the set of signals received through each beam of the set of beams, each received power may be associated with a beam of the set of beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may identify a scaling factor associated with determining a periodicity of backhaul physical random access channel (PRACH) resources. The wireless communication device may determine, based at least in part on the scaling factor, the periodicity of the backhaul PRACH resources. The periodicity of the backhaul PRACH resources may be extended as compared to a periodicity of access PRACH resources. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

Abstract: In a mmW network, a UE and a base station may establish a link using a RACH procedure. Because mmW and other band communications may rely on accurate beamforming to overcome link attention, the UE may need to provide beam information feedback to the base station. In particular, the UE may receive a beam-formed message from the base station during the RACH procedure. The UE may determine beam information based on the received beam-formed message during the RACH procedure. The UE may transmit a message to the base station during the RACH procedure, and the message may include the determined beam information.

Abstract: A first RAN may determine beamforming information for a UE served by the first RAN. Then, the first RAN may transmit, to a second RAN or a core network, paging information for the UE served by the first RAN, wherein the paging information comprises the beamforming information for the UE. A core network component, e.g., an AMF, may receive the paging information comprising the beamforming information for the UE and may send a paging request to a second RAN for the transmission of a paging message to the UE, wherein the paging request is based on the received paging information. The second RAN may receive, from the first RAN or from the core network, paging information for the UE comprising beamforming assistance information for the UE. The second RAN may then transmit a paging message to the UE based on the beamforming assistance information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.

Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.

Abstract: Certain aspects of the present disclosure provide techniques for carrier independent signal transmission and reception. Certain aspects provide a method for wireless communication. The method includes applying, at a device, a phase correction to a first signal to compensate for a difference between a first zero tone location comprising a first frequency and a second zero tone location comprising a second frequency. The method further includes one of: transmitting the first signal after applying the phase correction; or receiving the first signal prior to applying the phase correction.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive remaining minimum system information (RMSI) from a base station (BS); determine an initial active uplink bandwidth part based at least in part on the RMSI; and use the initial active uplink bandwidth part for a random access channel (RACH) procedure between the UE and the BS. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques and apparats for remaining minimum system information (RMSI) physical downlink control channel (PDCCH) monitoring. A method for wireless communications by a user equipment (UE) is provided. During initial access of a cell, the UE determines a default first periodicity to monitor for at least a first PDCCH scheduling RMSI. After the initial access, the UE determines a second periodicity to monitor at least a second PDCCH scheduling RMSI based on the default first periodicity or based on an indication received in a previous RMSI from the cell. The UE monitors for at least the first PDCCH during initial access at the default first periodicity and monitors for at least the second PDCCH at the second periodicity after the initial access.
