  • Patent number: 10630404
    Abstract: A method of performing received signal strength indication (RSSI) measurements in new radio (NR) networks is proposed. 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.

  • Publication number: 20200107337
    Abstract: Apparatus and methods are provided for L1-RSRP. 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).

  • Publication number: 20190393980
    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.

  • Patent number: 10516465
    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 CSI-RS Measurement Timing Configuration (CMTC) is proposed. The CMTC timing window is specifically configured to UE for CSI-RS RRM/mobility measurement via Radio Resource Control (RRC) signaling. CMTC can be carrier-specific or measurement object (MO) specific configured. Multiple CMTC can be configured to a UE, in a carrier-specific or a measurement object (MO) specific fashion. For inter frequency measurement, one CMTC on a carrier can be configured. For intra frequency measurement, up to two CMTC on a carrier can be configured. The CSI-RS resources associated to a given cell shall be configured within one slot. The CSI-RS resources on a carrier can be configured in the carrier specific CMTC. A gap shall be configured to include the CMTC for inter-frequency measurement.

  • Publication number: 20190166513
    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.

  • Publication number: 20190132877
    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.

  • Patent number: 10206176
    Abstract: Concepts and examples pertaining to efficient coding switching and modem resource utilization in wireless communication systems are described. A processor of a modem of a user equipment (UE), configured with at least a first-capacity decoder and at least a second-capacity decoder, receives a common virtual carrier (CVC), a dedicated virtual carrier (DVC), or both. The CVC contains common information shared by multiple UEs, control information for the UE, and/or data information related to first data destined for the UE. The DVC contains control information for the UE, the first data, or a combination thereof. The first-capacity decoder decodes data of a small size up to a low data rate. The second-capacity decoder decodes data of a large size up to a high data rate. The processor determines whether to decode the first data using the first-capacity decoder or the second-capacity decoder based on the data information in the CVC.

  • Publication number: 20180368152
    Abstract: A method of configuring and applying UE beam training gaps for simultaneous UE beam training and data reception in a beamforming wireless communication system is proposed. UE beam training gaps are configured by the base station for each UE. Typically, UE-specific data transmission can take place during the serving control beam time region. The UE beam training gaps are periods where UE-specific data transmission does not happen within the serving control beam time region. During each UE beam training gap, non-serving UE beam training can take place, where the UE performs intra-frequency reference signal measurements from serving and/or neighbor cells using various non-serving UE beams. The UE beam training gaps are configured and signaled to each UE, and each individual UE can have different data occupancy region within its serving CB time region.

  • Publication number: 20180167164
    Abstract: A method for URLLC transmission with UE blind detection on scheduling information is proposed. Since increased control channel reliability requires increased physical resource, it is proposed to exploit UE blind detection on part of the URLLC data burst to trade-off control channel reliability with reduced physical radio resource for URLLC transmission. The URLLC burst is encoded to a plurality of low-density parity-check (LDPC) code blocks (CBs), and UE blindly decodes over multiple candidate configurations of the first data CB, and then the non-signaled scheduling information and the first data CB are successfully retrieved passing CRC check, where the CRC of longer size is added to the first data CB. The proposed method leverages UE blind detection and higher layer signaling to carry part of scheduling information to reduce control channel payload, which saves physical radio resource and improves reliability.
