Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may measure a RSRP of a CRS for each of a plurality of neighboring cells. The apparatus may also calculate an interference strength of each of the plurality of neighboring cells based on the RSRP measurement of the CRS for each of the plurality of neighboring cells. Additionally, the apparatus may compare a PDSCH demodulation performance of the UE based on rate matching for a CRS offset associated with each of the plurality of neighboring cells with the PDSCH demodulation performance of the UE based on skipping the rate matching for the CRS offset. The apparatus may also transmit a request for the rate matching or skipping the rate matching for the CRS offset based on the comparison of the PDSCH demodulation performance of the UE.

Abstract: Disclosed embodiments facilitate UE location determination in systems with dense PRS configurations, reduced PRS periodicity, frequency hopping, and involving UE inter-frequency measurements. The techniques may be applied to Bandwidth reduced-Low complexity (BL) UEs, or enhanced Machine Type Communication (eMTC) UEs or Further enhanced MTC (FeMTC) UEs and/or in LTE-M systems. A method on a UE may comprise: receiving a Reference Signal Time Difference (RSTD) measurement request; transmitting, in response to the RSTD measurement request, a dedicated gap request comprising a requested configuration of dedicated gaps; and receiving, in response to the dedicated gap request, a message comprising a dedicated gap configuration. The dedicated gap request may comprise a request for dedicated measurement gaps and the message may comprise a dedicated measurement gap configuration. In some embodiments, the dedicated gap request may comprise a request for dedicated autonomous gaps and the message may comprise a dedicated autonomous gap configuration.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines whether a timing offset between a PCC and an SCC possibly exceeds a threshold. In addition, the apparatus switches an amplifier gain utilizing one of a first set of gain states or a second set of gain states based on the determination that the timing offset possibly exceeds the threshold. The first set of gain states includes a first number of gain states, and the second set of gain states includes a second number of gain states less than the first number of gain states.

Abstract: Methods, systems, and devices for wireless communications are described that support overlapping physical downlink control channel (PDCCH) candidate thresholds. In some examples, a user equipment (UE) may determine, for each subcarrier spacing (SCS) configuration of a set of SCS configurations, a threshold number of overlapping PDCCH candidates within a time interval. The UE may receive, from a base station, signaling indicating one or more PDCCH monitoring configurations. In some examples, the UE may monitor the PDCCH for control information according to the one or more PDCCH monitoring configurations and a number of overlapping PDCCH candidates, where the number of overlapping PDCCH candidates may satisfy (e.g., be less than or equal to) the threshold number of overlapping PDCCH candidates.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may determine a downlink (DL) positioning reference signal (PRS) measurement period for measuring and processing DL PRSs transmitted by a base station while the UE is in a radio resource control (RRC) INACTIVE state. While in the RRC INACTIVE state, the UE may measure and process DL PRSs during the DL PRS measurement period. In another aspect, a network entity may receive one or more parameters associated with a capability of a UE to measure and process DL PRSs while the UE is in a RRC INACTIVE state. Based on those parameters, the network entity may determine a DL PRS measurement period to be used by the UE while the UE is in the RRC INACTIVE state. The network entity may send, to the UE, information for determining the DL PRS measurement period.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may transmit reference signals bursts during an initial beam pairing (IBP) resource. In some examples, each reference signal burst may include an occasion for transmitting a reference signal of a set of reference signals. A second UE may measure the reference signals during the IBP resource and may determine a beam for sidelink communications with the first UE based on measuring the set of reference signals. The second UE may transmit a response message during a response occasion of the IBP resource, where each response occasion within the IBP resource corresponds to a respective reference signal of the set of reference signals. As such, the second UE may transmit a response message during a response occasion that corresponds to the reference signal associated with the selected beam, thereby indicating the selected beam to the first UE.

Abstract: Aspects presented herein may enable a base station to perform demodulation reference signal (DMRS)-based channel sounding for a channel between the base station and a UE, such that the base station may configure a more suitable precoding for coherent UL multiple input multiple output (MIMO) transmission(s) of the UE without increasing communication overhead significantly or at all. In one aspect, a base station performs channel sounding for a channel based on a set of physical uplink shared channel (PUSCH) DMRS received from a UE via the channel. The base station selects a precoding to be used by the UE for a subsequent PUSCH transmission via the channel based on the channel sounding. The base station transmits, for the UE via a physical downlink control channel (PDCCH), a transmit precoder matrix indicator (TPMI) indicating the selected precoding, where the PDCCH schedules the subsequent PUSCH transmission for the UE.
