Abstract: When a first node is subject to a maximum permissible exposure (MPE) condition, it may be beneficial for the first node to signal, to a second node, an uplink beam to be used for communications and/or one or more properties of the uplink beam. For example, the first node may signal a downlink beam, from a first reciprocal beam pair, and an uplink beam, from a second reciprocal beam pair, to be used for communications, and/or may signal one or more properties of the uplink beam and/or the downlink beam. Additionally, or alternatively, the second node may transmit, to the first node, a signaling state (e.g., a transmission configuration indication (TCI) state) that indicates properties to be used to configure an uplink beam and/or a downlink beam. In this way, the first node and the second node may configure beams in a manner that accounts for MPE limitations.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

Abstract: Aspects of the present disclosure provide a mechanism for flexible scheduling of grants for downlink or uplink transmissions. In some examples, a grant may be scheduled using multiple control signals, where subsequent control signals may modify one or more properties of the grant. For example, the grant may be modified to add a packet to the grant for transmission on a different set of time-frequency resources or a different set of multiple-input multiple-output (MIMO) layers, modify a time-frequency resource allocation of the grant, modify the waveform utilized for the grant, modify the transmit-diversity scheme utilized for the grant, or indicate specific processing for the packet.

Abstract: Methods, apparatuses, and computer-readable mediums associated with a user equipment (UE) and a base station are provided for herein. In aspects, a UE may receive, from a base station, a beam modification command indicating at least one beam index for communicating through at least one beam on at least one channel. In an aspect, each beam index of the at least one beam index may indicate at least a direction for communicating through a corresponding beam of the at least one beam. The UE may communicate, with the base station, through the at least one beam corresponding to the at least one beam index on the at least one channel.

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 demodulation reference sequence (DMRS) of a plurality of DMRSs for transmission in a synchronization signal block (SSB) based on a half-frame in which the SSB is transmitted. The method further includes transmitting the selected DMRS in the SSB.

Abstract: A user equipment (UE) may be outside of the coverage area of a base station or other access point, which may impede access by the UE of a core network, server, or the like. Therefore, a UE may establish a relay connection to access resources when the UE is outside of a coverage area provided by a base station or access point. In aspects, an apparatus may be configured to transmit, to a set of relay UEs, a first message associated with establishment of a relay connection. The apparatus may be further configured to receive a set of messages from the set of relay UEs. The apparatus may be further configured to establish the relay connection with a first relay UE of the set of relay UEs based on a message of the set of messages from the first relay UE.

Abstract: Various features related to using a multi-port synchronization signal as reference for demodulating a multi-port broadcast channel are described. In an aspect, a synchronization signal, e.g., SSS, may be repurposed to serve as a demodulation reference for a downlink channel, e.g., PBCH, thereby obviating the need for a base station to send an additional reference signal for PBCH demodulation. A base station may select two or more logical antenna ports to transmit a synchronization signal, transmit the synchronization signal from the selected two or more logical antenna ports, and transmit information on the PBCH, from at least the selected two or more logical antenna ports. A UE may receive the synchronization signal from the two or more logical antenna ports at the base station, receive information on the PBCH from the at least the two or more logical antenna ports, and demodulate the information based on the received synchronization signal.

Abstract: Methods, systems, and devices for wireless communication are described. A network device, such as a base station, may transmit a set of reference symbols to a user equipment (UE). Each set of reference symbols may include two (or more) beamformed signals. The network device may receive, based on the set of reference symbols, a measurement report from the UE. The measurement report may include a co-phasing indicator associated with the set of reference symbols. The network device may identify, based at least in part on the measurement report, an antenna port precoder configuration to use for communicating with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide a mechanism for a user equipment (UE) to identify an uplink transmit beam to be used for communicating with a base station. In some cases, the uplink transmit beam may be based on a recent uplink (or downlink) transmission or set of allocated resources. A base station may allocate communication resources for a UE. The UE may determine, based on the allocated communication resources, a default transmit beam for communicating with the base station. The UE and base station may (e.g., independently) identify a triggering condition for using the default transmit beam. The UE may transmit an uplink communication to the base station using the default transmit beam based on the triggering condition.
