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.

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: Apparatus and methods are provided for RRM measurement in the NR network. In one novel aspect, the RRM measurement is configured with one measurement gap for SS block and CSI-RS. In one embodiment, an extended MGL (eMGL) is configured such that the SS block and CSI-RS is measurement within one measurement gap. In another embodiment, the shorter MGL (sMGL) that is shorter than the standard MGL is configured. In another novel aspect, the CSI-RS is allocated adjacent to the SS blocks such that one measurement gap is configured for both the SS block and CSI-RS measurement. In another novel aspect, the CSI-RS measurement is conditionally configured. In yet another novel aspect, the UE decodes the time index of the SS block conditionally.

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.

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.
