摘要: Systems and methods of selecting a PRACH resource opportunity are described. One of multiple Synchronization Signal Blocks (SSBs) is received. Each SSB has PSSs, SSSs and a PBCH that contain system information. A RACH occasion (RO) is selected from among multiple ROs associated with the SSB. A PRACH is transmitted on resources of the RO. The ROs are configured in a TDM and/or FDM manner. The RO is selected randomly or, if TDM is used, an earliest of the ROs from a UE-initiated RACH transmission in a previous period. A preamble of the RO is selected randomly with equal probability.

摘要: Embodiments of the present disclosure describe apparatuses, systems, and methods for initialization of pseudo noise (PN) sequences for reference signals and data scrambling. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; and initialize the second M-sequence of the PN sequence with a compressed value. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; initialize the second M-sequence of the PN sequence with a part of the initialization parameters; and shift the PN sequence by another part of the initialization parameters. Some embodiments may be to initialize the first M-sequence of the PN sequence with a part of the initialization parameters; and initialize the second M-sequence of the PN sequence with another part of the initialization parameters. The embodiments may lead to a more efficient hardware design.

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: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message comprising an indicator to indicate a number of contention based physical random access channel (PRACH) preambles within a PRACH occasion per Synchronization Signal Block (SSB). The second circuitry may be operable to generate a first PRACH occasion, based on the indicator.

摘要: Embodiments of a Machine Type Communication User Equipment (MTC UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The MTC UE may determine a system timing based on reception of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). The MTC UE may receive, from the gNB, radio resource control (RRC) signaling that indicates one or more parameters of a configurable resynchronization signal (RSS). The RSS may be for resynchronization, by the MTC UE, after the MTC UE awakens from a power save mode. The parameters of the RSS in the RRC signaling may depend on a target coverage of the MTC UE. The MTC UE may determine an updated system timing based on reception of the RSS.

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: 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: 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.
