Abstract: Certain aspects of the present disclosure relate to methods and apparatus for blind detection of cell-specific reference signals. Methods and apparatus are provided for detecting a cell-specific reference signal (CRS) in an orthogonal frequency division multiplexed (OFDM) symbol by a user equipment (UE). The method generally includes predicting a current channel response of a current OFDM symbol based on a channel response of at least one previous OFDM symbol, estimating a noise power level of the current OFDM symbol, forming a log likelihood ratio (LLR) of two detection hypotheses based on the predicted current channel response and the estimated noise power level, comparing the LLR to a pre-determined threshold, and determining that at least one CRS is present in the current OFDM symbol based on the comparison.

Abstract: This disclosure provides systems, methods, and apparatuses for sharing a maximum transmit power limit between a first radio access technology (RAT) and a second RAT. In one aspect, a wireless communication apparatus may reduce the maximum transmit power limit of a first uplink signal associated with the first RAT to obtain a first transmit power. The wireless communication apparatus may allocate a second transmit power remaining from the maximum transmit power limit to a second uplink signal associated with the second RAT. The wireless communication apparatus may reduce the maximum transmit power limit when the wireless communication apparatus is located at a cell edge, and a higher priority of the first RAT in relation to the second RAT may otherwise result in the second transmit power of the second uplink signal not satisfying a threshold.

Abstract: A UE may identify a first set of preserved resources of one or more sets of preserved resources. An aircraft-borne device may identify a first set of preserved resources of one or more sets of preserved resources. The first set of preserved resources may be associated with a time domain starting point, a time domain duration, and a frequency domain resource allocation. The UE may transmit, to an aircraft-borne device and the aircraft-borne device may, receive from the UE, over at least part of the first set of preserved resources, a synchronization signal and a first payload message. The first payload message may include a first emergency message and may be transmitted and received via one of a first PUSCH, a first PSSCH, or a PSCCH. The aircraft-borne device may forward, to a base station or another aircraft-borne device, at least the first emergency message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, during a beam management procedure, multiple sets of channel state information reference signals (CSI-RSs). The UE may receive multiple CSI-RSs, wherein one CSI-RS of the multiple CSI-RSs is associated with one set of CSI-RSs of the multiple sets of CSI-RSs, and wherein a beam associated with the one CSI-RS corresponds to a beam associated with the one set of CSI-RSs. The UE may transmit multiple channel quality indicator (CQI) reports based at least in part on the multiple CSI-RSs, wherein one CQI report of the multiple CQI reports is based at least in part on the one CSI-RS of the multiple CSI-RSs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that configures transmission configuration indicator (TCI) states based at least in part on aperiodic channel state information reference signals (AP-CSI-RSs), where each TCI state includes a first resource that is an aperiodic tracking reference signal (AP-TRS) and a second resource that is an AP-CSI-RS. The UE may receive first downlink control information that triggers a first AP-CSI-RS resource set that includes AP-CSI-RSs that are each associated with a quasi-co-location (QCL) Type-D resource. The UE may transmit a report that indicates one or more AP-CSI-RSs. The UE may receive an activation command that activates a TCI state associated with a first narrow beam, where a combination of a first AP-CSI-RS and a first associated QCL Type-D resource uniquely indicates the first narrow beam. Numerous other aspects are described.

Abstract: Method and apparatus for control signaling for SIC operation in 2-codeword operating mode. The apparatus transmits, to a network entity, a SIC capability indication comprising an indication that the UE supports a SIC operation for 2-CW allocation and an order of processing a first codeword and a second codeword. The apparatus monitors for an ACK to enable the SIC operation between the UE and the network entity. The apparatus receives downlink communication based on the SIC operation in response to receiving the ACK to enable the SIC operation. The apparatus may process the first codeword, within the downlink communication, transmitted based on a first MCS. The apparatus may cancel interference from the downlink communication based on the first codeword to obtain the second codeword, within the downlink communication, transmitted based on a second MCS.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE may partially disable transmissions on a transmission port based on a temperature condition (e.g., chipset temperature or skin temperature exceeding threshold). In a further aspect, the UE may enable the partially disabled transmissions on the transmission port in response to cessation of the temperature condition. In a further aspect, the UE may transmit a capability indication to a base station that indicates that the UE is capable of supporting a transition from a multi-layer (rank-2) communication mode to a single-layer (rank-1) communication mode.

Abstract: Some aspects of the present disclosure provide channel state information (CSI) processing criteria. A method that may be performed by a user equipment (UE) generally includes receiving, from a base station via a first bandwidth part (BWP), control signaling that triggers reporting at least one of a first channel state information (CSI) report associated with the first BWP or a second CSI report associated with a second BWP that is non-active, determining, based on an indication of an active downlink (DL) BWP change, at least one occupation time of one or more CSI processing units (CPUs) associated with the first CSI report or the second CSI report, and taking one or more actions based at least in part on the at least one occupation time.
