摘要： A variable sub-carrier mapping method comprising steps of: applying different bit interleaving schemes to different transmissions of a hybrid automatic retransmission request (HARQ) process in side of transmitter; and in the side of the transmitter, modulating symbols onto sub-carriers for transmitting. Different transmissions in one HARQ process adopt different bit interleavers or different symbol-to-sub-carrier mapping methods so as to realize that the same bit of different transmissions in one HARQ process is transmitted via different sub-carriers. Therefore, the system achieves the frequency diversity gain and reduces the probability of failure of HARQ transmission caused by that some bits are always transmitted via the sub-carrier with the same deep fading. In this way, the average HARQ retransmission times can be reduced and the system throughput can be improved.

摘要： An apparatus and system for reducing URLLC latency are described. A single packet mode is described in which, when a packet arrives at the PDCP layer for transmission, an indication is sent to a scheduler with the expected size of the packet after ciphering. The packet is then sent to the RLC layer and concurrently submitted to the ciphering engine to enable ciphering to occur in parallel with the other activities. The scheduler determines the expected TB size for transmission of the packet by determining the size of the PDCP, MAC, and RLC headers. The scheduler matches the resource allocation for transmission to the expected TB size.

摘要： Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH), wherein a cyclic redundancy check (CRC) of the PDCCH is scrambled by a radio network temporary identifier (RNTI). In some cases, if the RNTI that scrambles the PDCCH is a modulation coding scheme (MCS) cell RNTI (MCS-C-RNTI), cell RNTI (C-RNTI), or a configured scheduling RNTI (CS-RNTI), the UE may determine that: one or more PT-RSs are present in the PDSCH, a time density parameter of the PT-RSs is equal to one, and a frequency density of the PT-RSs is equal to two.

摘要： Embodiments of a User Equipment (UE) to support inter-frequency handover are disclosed herein. The UE may receive, from an Evolved Node-B (eNB), a measurement report configuration message that includes multiple measurement events to be determined at the UE. The UE may transmit a measurement report when a combined measurement event occurs. The combined measurement event may include a combination of the multiple measurement events according to a “logical AND” operator such that the combined measurement event occurs when the multiple measurement events occur. The measurement events may be related to signal measurements performed on one or more signals received at the UE from one or more cells configured for operation in the network.

摘要： Embodiments of UE and methods for measurement of Reference Signal Received Quality (RSRQ) are generally described herein. The UE may be configured to determine an RSRQ of a serving cell and an RSRQ of a target cell based on an indicated RSRQ measurement type. The measurement type may be received as part of a measurement configuration Information Element (IE) that indicates a first or second RSRQ measurement type. For the first RSRQ measurement type, the RSRQ may be determined based on a Received Signal Strength Indicator (RSSI) over common reference signals (CRS). For the second RSRQ measurement type, the RSRQ may be determined based on an RSSI that is based on a received power of one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols received at the UE.
