Abstract: In order to maintain conformance with exposure limits, in band measurements may be performed. A method, a computer-readable medium, and an apparatus may be provided for wireless communication at a user equipment. The apparatus receives an indication of a cell specific resource, e.g., a cell specific resource available for MPE measurement. The apparatus then performs a measurement based on the cell specific resource and determines whether to adjust a transmission characteristic of the user equipment based on whether the measurement meets a threshold. In another aspect a base station apparatus may configure a cell specific resource in which a user equipment may perform an MPE measurement and control use of the cell specific resource for the MPE measurement.

Abstract: Various aspects of the disclosure relate to communicating random access information and uplink control information. In some aspects, a user equipment (UE) or other suitable apparatus transmits physical uplink control channel (PUCCH) information concurrently with random access channel (RACH) information transmitted by another UE or other apparatus. For example, the RACH access information and the PUCCH information may be frequency division multiplexed orthogonal tones. The disclosure relates in some aspects to using downlink-uplink (DL-UL) channel reciprocity to determine symbol and/or tone locations. For example, a base station or other suitable apparatus may initially sweep across different directions in different time slots to transmit signals during a synchronization sub-frame. A UE or other suitable apparatus can then find an appropriate RACH symbol from its best synchronization beam index and transmit PUCCH information in those symbols.

Abstract: Various aspects directed towards performing a random access procedure are disclosed. In one example, a parameter is identified from a plurality of parameters, and an uplink (UL) resource associated with a random access procedure is selected based on a value associated with the parameter. A random access procedure communication is then transmitted via the selected UL resource. In another example, different parameters are supported by a scheduling entity such that each of the parameters has a corresponding plurality of different potential values. Here, the scheduling entity enables a scheduled entity to select an UL resource to perform a random access procedure based on a value corresponding to a particular one of the parameters. A random access procedure communication is then received from the scheduled entity via the UL resource.

Abstract: Aspects of the present disclosure provide for random access channel (RACH) configuration in wireless communication systems. In some examples, a RACH configuration may be selected for use by a scheduled entity in transmitting a RACH signal to a scheduling entity based on an estimated timing advance value. The RACH configuration may include, for example, a transmission time of the RACH signal and/or a RACH waveform configuration identifying at least a cyclic prefix (CP) length and a guard time (GT) for the RACH signal. In some examples, the CP and GT length may each be set to the difference between an estimated maximum round-trip time (RTT) and an estimated minimum RTT between the scheduled entity and the scheduling entity. In some examples, the timing advance value may be estimated as the estimated minimum RTT.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for communicating remote and local data in a wireless fronthaul of a wireless communication system. The method includes terminating a lower portion of a radio bearer for the UE, wherein the radio bearer comprises an upper portion and a lower portion. The method further includes forwarding the upper portion of the radio bearer for the UE to a network node over a wireless link. The method further includes carrying a lower portion of a second radio bearer with the BS and a multiplexing layer indicating whether the lower portion of the second radio bearer includes an upper portion of the second radio bearer corresponding to local data or a tunnel with the upper portion of the radio bearer for the UE corresponding to remote data.

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 UE may identify a first indication associated with a first signaling to be received in a time interval and identify a second indication associated with a second signaling to be received in the time interval. The UE may select to receive and receive, in the time interval, at least one of the first signaling or the second signaling based on at least one of the first or second indications. One or more of the first and second indications may be received from a BS or determined by the UE via predefined or other means. A BS may convey indications of the first and/or second signaling. The first and second indications may be transmitted sufficiently before the signaling in an effort to allow the UE to select and tune its receiver beam in the direction of the signaling to be received.

Abstract: Aspects of the present disclosure provide methods, apparatuses, and embodiments for transmitting time critical uplink (UL) control information (e.g., beam failure indication, buffer status report, and scheduling request) without first obtaining UL timing synchronization with a network. Therefore, UL communication latency may be reduced by removing the signaling overhead involved in performing a full random access procedure to obtain UL synchronization prior to UL transmission.

Abstract: In order to improve cell detection in NR, a user equipment apparatus performs a PSS search on a first frequency raster from a group of frequency rasters. When the UE detects a PSS on the first frequency raster corresponding to a PSS hypothesis, the UE searches for an SS on a second frequency raster based at least on part on the detected PSS hypothesis on the first frequency raster. The UE may search for a plurality of hypotheses of the SS corresponding to the detected PSS hypothesis on the first frequency raster and the second frequency raster. The second frequency raster may be selected from the group of frequency rasters based at least in part on the detected PSS hypothesis or the first frequency raster on which the PSS was detected.
