摘要： A user equipment (UE) configured for operating in a fifth-generation (5G) new radio (NR) network may monitor search space sets for a number of physical downlink control channel (PDCCH) candidates within a number of non-overlapped control-channel elements (CCEs) for a primary cell (PCell). The number of PDCCH candidates and the number of non-overlapped CCEs may include PDCCH candidates and non-overlapped CCEs on a scheduling secondary cell (SCell). The scheduling SCell may be an SCell that schedules a transmission on the PCell. The UE may decode one or more of the PDCCH candidates on the scheduling SCell for a downlink control information (DCI) format which may schedule a physical downlink shared channel (PDSCH) transmission and/or a physical uplink shared channel (PUSCH) transmission of the PCell.

摘要： Embodiments of a user equipment (UE) configured for new-radio (NR) operations in a fifth-generation (5G) system (5GS) may be configured to detect a downlink-control information (DCI) format that includes a one-shot hybrid automatic repeat request acknowledgement (HARQ-ACK) request field and a frequency domain resource assignment field (FDRA). The one-shot HARQ-ACK request field may indicate whether one-shot HARQ-ACK feedback is triggered. The UE may decode the FDRA field to determine whether the FDRA field indicates a valid frequency resource or whether the FDRA field indicates a special value and may also be configured to determine whether or not a physical downlink shared channel (PDSCH) is scheduled by the DCI format and whether or not secondary cell (SCell) dormancy switching is triggered based on both the one-shot HARQ-ACK request field and the FDRA field. The UE may also encode a HARQ-ACK transmission on a physical uplink control channel (PUCCH). The HARQ-ACK transmission may be encoded to include HARQ-ACK feedback for PDSCH transmissions for all HARQ processes of a cell when the one-shot HARQ-ACK feedback is triggered.

摘要： Systems and methods for interlace PUCCH transmission in 5G networks are described. The gNB sends an RRC message to a UE. The RRC message provides one or more PUCCH interlace allocations within a BW. Each PUCCH interlace allocation has a PUCCH format for each PUCCH interlace. Each PUCCH format contains a different PUCCH interlace index. The UE sends a PUCCH interlace in the BWP based on the PUCCH interlace allocation. A PUCCH in the allocated PUCCH interlace has a cyclic shift that is dependent on a resource block number in the allocated PUCCH interlace within the BWP.

摘要： A user equipment (UE) for operation in a fifth-generation new radio (5G NR) network may be configured with two or more secondary cells (SCells) of a group of SCells. In these embodiments, the UE may monitor a physical downlink control channel (PDCCH) for detection of a downlink control information (DCI) format 1_1. The UE may interpret the DCI format 1_1 as indicating SCell dormancy, rather than scheduling a physical downlink shared channel (PDSCH) reception, if the UE is configured with resourceAllocationType1 and if all bits of a frequency domain resource assignment field in the DCI format 1_1 are equal to 1. For SCell dormancy, the UE may interpret fields of the DCI format 1_1 as a bitmap for SCell dormancy indication and either activate or deactivate a downlink bandwidth part (DL BWP) for an SCell of the group of configured SCells when indicated by the bitmap.

摘要： Embodiments of a Next Generation Node-B (gNB) and User Equipment (UE) are generally described herein. The gNB may transmit control signaling to configure transmission of position reference signals (PRSs) by a plurality of transmit-receive points (TRPs). The gNB may receive, from the UE, for each of the TRPs, a set of signal location parameters (SLPs). The gNB may perform an iterative process to estimate a position of the UE. For a current iteration, the gNB may: determine a current estimate of the position of the UE based on a current plurality of sets of SLPs; and determine a cost function for each of the current plurality of sets of SLPs. The gNB may determine, based on the cost functions, a next plurality of sets of SLPs for a next estimate of the position of the UE.

摘要： The present invention relates to a method for transmitting and receiving data in a wireless access system and a terminal therefor. The method comprises the steps of: receiving an instruction message which instructs transmission of uplink resource allocation information via a physical downlink shared channel (PDSCH) from a base station; determining whether the resource allocation information is a first downlink resource allocation information based on the instruction message, upon receiving resource allocation information set to a flag value that indicates uplink resource allocation information, from the base station via a physical downlink control channel (PDCCH); receiving uplink resource allocation information via the PDSCH according to the first downlink resource allocation information from the base station; and transmitting uplink data to the base station via a physical uplink shared channel (PUSCH) according to the uplink resource allocation information.

摘要： The present invention relates a method for a terminal to transmit acknowledgement information including determining a physical uplink control channel (PUCCH) format and resource, in which acknowledgement information is transmitted in response to a downlink transmission in a downlink sub-frame set including M (M≧1) downlink sub-frame; and transmitting the acknowledgement information using the PUCCH format and resource in one uplink sub-frame. Here, one or more serving cells including one PCell and at least one SCell are configured to the terminal. In the determining step, the acknowledgement information may be transmitted using a PUCCH format 1a/1b, when a semi-persistent scheduling release physical downlink control channel (PDCCH) does not exist in the downlink sub-frame set, and one physical downlink shared channel, which is indicated through the detection of a corresponding PDCCH having a downlink assignment index value of one, exists in the downlink sub-frame set.

摘要： In dual connectivity, a UE is served by cells are operated in different eNBs with one eNB designated as the master eNB (MeNB) and the other as a secondary eNB (SeNB). A random access procedure is described by which a UE connected to an MeNB may attempt to acquire access to an SeNB cell. The procedure may utilize the backhaul connection between the SeNB and the MeNB so that the random access response may be transmitted over an MeNB cell.
