Abstract: Distributed resource allocation for devices can be facilitated via a priority sequencing scheme. The priority sequencing scheme can mitigate source device collisions by assigning priority values to source devices and channels associated with the source devices. Various priority sequencing can be used based upon whether source devices can only communicate with a limited number of sink devices or whether source devices can communicate with all sink devices.

Abstract: Aspects of the disclosure provide a method and an apparatus. For example, the apparatus can include receiving circuitry and processing circuitry. The receiving circuitry can be configured to receive from a cell a Q number and one or more SSBs within DRS transmission windows associated with the cell. The processing circuitry can be configured to, for each of the DRS transmission windows, perform a modulo operation on position indexes of the SSB with the Q number to determine SSB beam indexes (SBIs) of the SSBs. A remainder of each of the position indexes is an SBI of one of the SSBs that corresponds to the position index. The processing circuitry can be further configured to combine RRM measurements of the SSBs within the DRS transmission windows based on the SBIs of the SSBs to determine the quality of the cell.

Abstract: Aspects of the disclosure provide apparatuses and methods for wireless communications. One apparatus includes processing circuitry that selects one or more first available radio link monitoring reference signal (RLM-RS) samples from a plurality of received RLM-RS samples based on signal qualities of the one or more first available RLM-RS samples. The one or more first available RLM-RS samples are received within a first evaluation period. The processing circuitry determines whether a total number of the one or more first available RLM-RS samples is less than a target number. When the total number of the one or more first available RLM-RS samples is determined to be less than the target number, the processing circuitry determines a second evaluation period that is greater than the first evaluation period, and performs an RLM procedure in an unlicensed band within the second evaluation period.

The UE receives, through a non-physical layer signaling, a configuration indicating to receive a first reference signal in a set of OFDM symbols in a first slot. The UE attempts to detect a physical layer signaling in the first slot or in a second slot prior to the first slot. The UE refrains from conducting measurements of the first reference signal, when the physical layer signaling is detected by the UE and includes a first indication.

Abstract: Apparatus and methods are provided for NR CSI-RS based BFD/RLM in FR2. In one novel aspect, BFD in FR2, the evaluation period is extended by the N factor if the CSI-RS for BFD is in a resource set configured with repetition ON or the BFD is performed on CSI-RS#1 without beam information or, where the CSI-RS#1 is configured without beam information if CSI-RS for BFD is not QCL-TypeD with SSB for L1-RSRP beam reporting, nor the CSI-RS for BFD is not QCL-TypeD with CSI-RS for L1-RSRP beam reporting. In one embodiment, the N factor equals to 1 only when at least one predefined RX beam information is included in the RRC configuration.

In one novel aspect, the CBD evaluation period uses the uniformed scaling factor and the base period for the CBD evaluation period is the same when no DRX is configured and when the DRX is configured with DRX cycle length smaller than or equals to a predefined threshold. In one embodiment, the UE receives DRX configuration including a DRX cycle length, determines a base period for an evaluation period of CBD measurements based on the DRX cycle length and determines a multiplicator for the evaluation period based on a scaling factor and one or more measurement factors, and performs CBD measurements based on the evaluation period, wherein the evaluation period is based on the determined base period and the multiplicator. In one embodiment, the scaling factor is the same for all DRX configurations.

When RSSI-Measurement time slots and OFDM symbols are configured by high-layer signaling, UE can assume the timing reference of a target carrier is the frame boundary of the serving cell or any detected cells on that carrier. UE then performs RSSI measurements according to the timing reference and the configured RSSI-Measurement slot/symbol. UE derives the timing location of the configured slot/symbol according to the timing reference and the subcarrier spacing (SCS) of the synchronization signal block (SSB) in the target carrier.

In one novel aspect, L1-RSRP are performed in a measurement period based on measurement factor P and N, which are determined based on configuration information. The UE performs scheduling restriction when the measurement factor N indicates scheduling restriction is needed. In one embodiment, the L1-RSRP measurement period is extended by N to compensate the L1-RSRP measurement for receiving beam training. In another embodiment, the L1-RSRP measurement period further depends on a second measurement factor P, wherein the measurement period is extended by P to compensate the L1-RSRP measurement for one or more reference signal (RS) overlapping. In one embodiment, the RS overlapping occurs for at least one overlapping occasion comprising the L1-RSRP overlaps with SSB measurement timing configuration (SMTC), the L1-RSRP overlaps with measurement gap (MG).

Abstract: Methods are proposed to define UE behavior for performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. In a first novel aspect, if CSI-RS based RLM-RS is not QCLed to any CORESET, then UE determines that CSI-RS RLM configuration is error and does not perform RLM accordingly. In a second novel aspect, SSB for RLM and RLM CSI-RS resources are configured with different numerologies. UE perform SSB based RLM and CSI-RS based RLM based on whether the SSB and CSI-RS resources are TDMed configured by the network. In a third novel aspect, when multiple SMTC configurations are configured to UE, UE determines an SMTC period and whether SMTC and RLM-RS are overlapped for the purpose of RLM evaluation period determination.

Abstract: A method for harmonized operation between radio link monitor and beam failure recovery is proposed. In one example, upon indication of unsuccessful recovery from beam failure, a counter is initiated to count a configured number of OOS indication before RLF is declared due to beam failure. In another example, upon indication of successful recovery from beam failure, a counter is initiated to count a configured number of IS indication before starting over RLM procedure on its previous observations on failed beams. As a result, either early RLF declaration or RLM reset may be triggered based on BFR procedure to more accurately maintain the link quality.

Abstract: A method of channel state information reference signal (CSI-RS) radio resource management (RRM) measurement is proposed. A UE receives RRM measurement configuration from a BS via RRC signaling. The RRM measurement configuration comprises CSI-RS resource information, cell IDs, and associated SSB indication. The UE decides frequency resources of CSI-RS according to the configured RRC parameters. UE performs cell search within synchronization signal block (SSB) measurement timing configuration (SMTC) window to know the detected SSBs and the corresponding detected cell IDs and symbol timing of detected cells. UE then decides timing resources of the CSI-RS according to the timing reference. If the detected cell ID matches the cell ID configured for the CSI-RS resource, UE performs measurements on the CSI-RS resources based on the symbol timing of the detected SSB.
