  • Publication number: 20220070707
    Abstract: Certain aspects of the present disclosure provide techniques for adapting search, measurement, and loop tracking periodicities in new radio communications. A method that may be performed by a user equipment (UE) includes determining, based on one or more parameters, a first periodicity to perform a search to detect one or more component carriers (CCs), cells, beams, or a combination thereof; a second periodicity to perform measurement of one or more cells, beams, or both in one more detected CCs; and a third periodicity to perform loop tracking to monitor a downlink serving quality, an uplink serving beam quality, or both of a cell. The method may further includes performing the search at the determined first periodicity, measurement at the determined second periodicity, and loop tracking at the determined third periodicity.

  • Publication number: 20220053595
    Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.

    Abstract: Methods, systems and devices for wireless communications are described for differentiation between standalone (SA) and non-standalone (NSA) cells in a wireless communications system. A user equipment (UE) may receive an indication of a subcarrier offset for a system information block (SIB). The SIB may be for a cell of a wireless communications network. The cell may be in accordance with a radio access technology. The UE may determine, based on the subcarrier offset for the SIB, whether the cell is configured as an SA cell or as an NSA cell for the radio access technology. The UE may communicate via the wireless communications network based on whether the cell is configured as an SA cell or as an NSA cell.

  • Publication number: 20210345275
    Abstract: A UE is configured to determine a set of parameters associated with receiving the SSBs, the set of parameters including a first parameter bitmap associated with a serving cell, a second parameter bitmap associated with the neighbor cell, and the SMTC. The UE is configured to determine a search window for searching the received SSBs based on the SMTC and at least one of the first parameter bitmap or the second parameter bitmap. The UE may measure the SSBs searched during the determined search window and send measurement results associated with at least a subset of the measured SSBs to the base station. The UE may also prune measurements to generate the measurement results by removing measurements associated with SSBs received in slots that are not indicated to expect SSBs, based on the first parameter bitmap, the second first parameter bitmap, or the SMTC.

  • Publication number: 20210274468
    Abstract: Various aspects relate to acquisition of system information (SI). In some examples, a UE uses a guard timer to control how long the UE attempts to acquire a particular type of SI. In some examples, a UE that has entered a cell may determine whether there are any remaining paging occasions (e.g., that may indicate an SI update) during a period of time. If there is an insufficient number of paging occasions remaining (e.g., zero or one), the UE may monitor for broadcast SI. In some examples, after sending a request for SI to a base station, a UE may also periodically monitor for SI broadcast by the base station (e.g., to avoid potential delays in obtaining the SI). In some examples, if a UE does not acquire SI, the UE may use default SIB information (e.g., that expedites reselection to another cell).

  • Patent number: 11082920
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a set of base stations that are part of a synchronization group, where at least two of the base stations in the set of base stations operate on different frequencies. In some cases, the UE may identify the set of base stations based on an indication transmitted by a serving base station for the UE. Additionally, once the synchronization group is identified, the UE may schedule synchronization signals together from the set of base stations. For example, after identifying the set of base stations, the UE may identify a measurement timing window associated with the synchronization group and measure a respective synchronization signal for each base station within the measurement timing window. Accordingly, the UE may then transmit a measurement report to the serving base station that includes the synchronization signal measurements.

  • Publication number: 20210092003
    Abstract: Certain aspects of the present disclosure provide techniques for beam failure detection and recovery. A method that may be performed by a user equipment (UE) includes monitoring one or more first reference signals to detect a beam failure for one or more first control resource sets (CORESETs), transmitting an indication of the beam failure, and receiving a beam failure response after the transmission of the indication of the beam failure, wherein the monitoring of the one or more first reference signals for the detection of the beam failure stops in response to the reception of the beam failure response. The UE may then receive a configuration message after the reception of the beam failure response, and monitor, in response to the reception of the configuration message, one or more second reference signals to detect another beam failure for one or more second CORESETs.
