    摘要: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.

    摘要: Provided herein is design of early data transmission in wireless communication system. An apparatus for a user equipment (UE) includes a processor configured to: encode a physical random access channel (PRACH) sequence from a plurality of PRACH sequence for transmission via a PRACH to perform a random access procedure, wherein indication of support of early data transmission (EDT) that is transmitted during the random access procedure is based on at least one of the plurality of PRACH sequences, higher layer signaling, PRACH resources, PRACH formats, and a payload from the UE; and send the PRACH sequence to a radio frequency (RF) interface; and the RF interface to receive the PRACH sequence from the processor. Design of random access response (RAR) is also disclosed herein.

    摘要: Certain embodiments described herein use variable RTT for HARQ operations. Uplink HARQ may include, for example, for a first synchronous HARQ process, a UE selects first downlink resources to monitor for first HARQ feedback based on the first HARQ RTT value, and generates a first HARQ retransmission for first uplink resources in response to the first HARQ feedback. For a second synchronous HARQ process, the UE select second downlink resources to monitor for second HARQ feedback based on the second HARQ RTT value, and generates a second HARQ retransmission for second uplink resources in response to the second HARQ feedback. In certain embodiments, a RAN node signals or indicates the variable RTT values to the UE.

    摘要: Technology for a user equipment (UE), operable for monitoring a physical downlink control channel (PDCCH) is disclosed. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein the predetermined monitoring occasion has a periodicity of P slots or P symbols with an offset Os. The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein Os has San offset with respect to a first slot in subframe number zero (SFN#0). The UE can monitor a downlink (DL) control channel for DL control information (DCI) at a predetermined monitoring occasion, wherein P is a positive integer greater than zero.

    摘要: 5G methods and architectures to determine active SCells and their bandwidth parts (BWP) used in carrier aggregation (CA) are disclosed in which activating a BWP for an active SCell is performed initially according to a default value provided in initial radio resource control (RRC) messaging. After initialization, SCells and the SCell BWPs used by the user equipment (UE) are activated by RRC messaging, downlink control information (DCI) or dedicated medium access control (MAC) control elements (MAC CEs) with the initial BWP used for an activated SCell being a default value provided during initialization.
