Abstract: Methods, systems, and devices for wireless communications and capability signaling for enhanced handover processes are described. A user equipment (UE) may transmit, to a source base station, a band combination indicator to indicate at least one band combination supported by the UE. The source base station may transmit a source base station configuration and at least one band combination supported by the UE to a target base station for use during a handover procedure. The target base station may then transmit to the source base station, a target base station configuration to use in the handover procedure. The source base station may transmit to the UE, both base station configurations to be applied during the handover procedure which may include a number of band combinations. The UE may communicate during handover execution with both base stations using at least one band combination indicated in the received base station configurations.

Abstract: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: Handling of listen before talk (LBT) failures during radio resource control (RRC) procedures is disclosed. A user equipment (UE) may be configured to monitor for consistent uplink and downlink LBT failures on a bandwidth part (BWP) configured for a target cell. When the UE determines that consistent LBT failures are occurring with respect to the BWP, the UE may determine an LBT failure state on the BWP. In response, the UE may execute a recovery procedure, which may include selecting a new BWP associated with the target cell and having configured uplink resources, performing a cell reselection procedure, or switching to idle in order to perform cell selection. The UE may then report the LBT failures according to cell identification and BWP.

Abstract: Methods, systems, and devices for dynamic monitoring modes for synchronization signal block (SSB) transmissions are described. A user equipment (UE) may monitor one or more first SSB transmission opportunities for SSB transmissions from a base station and determine an SSB failure rate. Based on the failure rate, the UE may select a mode for monitoring one or more second SSB transmission opportunities. For example, if the failure rate is greater than a threshold, the UE may select a first mode for monitoring a first quantity of the one or more second SSB transmission opportunities. Additionally, if the failure rate is less than the threshold, the UE may select a second mode for monitoring a second quantity different than the first quantity of the one or more second SSB transmission opportunities. The UE may monitor the one or more second SSB transmission opportunities according to the selected mode for monitoring.

Abstract: A method, at a transmission/reception point (TRP), of producing a positioning reference signal muting pattern includes: obtaining, at the TRP, one or more positioning reference signal criteria, the one or more positioning reference signal criteria regarding at least one of positioning reference signal transmission or positioning reference signal reception; and producing, at the TRP, the positioning reference signal muting pattern such that the positioning reference signal muting pattern meets the one or more positioning reference signal criteria.

Abstract: Certain aspects of the present disclosure generally relate to randomization of positioning reference signal (PRS) frequency offsets and muting patterns in long term evolution (LTE) for enhanced observed time difference of arrival (eOTDOA). According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a base station (BS). The method generally includes randomly selecting at least one parameter used to determine a set of time-frequency resources for transmitting positioning reference signals (PRS) and transmitting PRS on the determined set of time-frequency resources. The user equipment (UE) may randomly select the at least one parameter used to determine the set of time-frequency resources to measure for the PRS from the BS and measure PRS on the determined set of time-frequency resources.

Abstract: Determining the early arrival path (EAP) based on a channel energy response (CER) can involve the use one or more masks to identify one or more peaks in the CER. Masks can be applied to the CER in an iterative process that can help identify the earliest peak corresponding to the EAP. Alias cancelation may also be implemented.
