摘要： Apparatuses, systems, and methods for sounding reference signal (SRS) coverage enhancement. A user equipment device (UE) may receive a configuration for SRS time domain bundling from a base station and may transmit, to the base station, at least one SRS transmission in accordance with the configuration. The configuration may include an indication of (and/or indicate) one or more SRS transmission occasions. The configuration may be communicated via higher layer signaling or physical layer signaling. The RRC parameter may be an SRS-ResourceSet parameter or an SRS-Resource parameter and may include a nrofSlots parameter to indicate the number of slots, where a slot may correspond to an SRS transmission occasion. The MAC CE may include at least four bits indicating the number of slots. The DCI may include at least one field indicating the number of slots.

摘要： Apparatuses, systems, and methods for selecting channel access mechanisms in wireless communications, and particularly in 3GPP NR-U. For example, an appropriate listen-before talk (LBT) channel access category (Cat) may be defined for certain messages, such as certain DL and/or UL control messages and certain RACH messages. For other messages, an appropriate Cat may be signaled by the base station, e.g., in a DCI message or SIB. Mechanisms are provided for the base station to signal to the UE certain channel access profile parameters, such as an appropriate LBT Cat, CAPC, and/or CP extension. Mechanisms are also provided for adjustment of contention window duration.

摘要： A base station and wireless communication (UE) may perform type II CSI-RS port selection based at least on partial reciprocity between an uplink path and a downlink path between the base station and the UE. The base station may identify dominant signal paths between the base station and the UE, based on measurements performed during uplink transmissions, and may transmit, to the UE, corresponding information indicative of CSI measurement and reporting configuration that may include a single measurement resource or multiple measurement resources. Each measurement resource may include multiple-port CSI-RS ports. The UE may indicate, to the base station, selection of a measurement resource when multiple measurement resources are configured, and may also report layer independent or layer common selection of a subset of CSI-RS ports included in the indicated single measurement resource or multiple measurement resources. Further enhancements include frequency domain compression enhancement and dynamic codebook parameter reconfiguration.

摘要： This disclosure relates to techniques for performing wireless communications by rapidly moving user equipment device in communication with a network. The UE may adapt communication techniques in response to the UE's motion. For example, reference signals may be transmitted by the UE to additional transmission and reception points and/or using different configurations. Similarly, the UE may receive reference signals from additional transmission and reception points.

摘要： Apparatus and methods are provided to for a user equipment (UE) to report channel state information (CSI) to a base station. The UE sends UE capability signaling to a base station to indicate support of a codebook for high speed scenarios. The UE processes configuration information from the base station for CSI reporting using the codebook. The configuration information indicates measurement resources for one or more downlink (DL) channel. The UE measures a channel response and interference using the measurement resources, generates CSI feedback using the codebook for at least one ray from the base station to the UE, and reports the CSI feedback to the base station.

摘要： A wireless communication system may use higher layer signaling to send transmission configuration indicator (TCI) parameters for a frequency band comprising the 52.6 GHz to 71 GHz range. A DCI message may be used to indicate an enabled TCI state for a channel occupancy time (COT). The wireless communication system may apply the enabled TCI state for the COT as indicated in the DCI message.

摘要： Systems, methods, and apparatuses for cross division duplex (XDD) operation in a wireless communication system are described herein. A user equipment (UE) is configured with one or more sub-bands (SBs) within a larger overall bandwidth (BW) (e.g., represented by a component carrier (CC), a bandwidth part (BWP), etc.), and that use uplink (UL)/downlink (DL) resource allocation(s) that may be different than the larger BW. Configurations for such SB-specific (SBS) arrangements that use guard bands (GBs) between SBs are discussed. Mechanisms for slot format indications (SFIs) within such SBs using either SBS DCI or cross-SB DCI are discussed. Mechanisms for providing SBS uplink resource for initial access (e.g., random access) using at least one initial UL BWP that is configured relative to one or more SBs and that may be used by XDD-capable UEs are discussed.

摘要： Techniques discussed herein facilitate generation of uplink control information for Enhanced Physical Uplink Control Channel (PUCCH) Format(s) (EPF(s)). One example embodiment employable in a User Equipment (UE) is configured to: determine Hybrid Automatic Repeat reQuest-Acknowledgment (HARQ-ACK) information; generate a PUCCH for a BandWidth Part (BWP) based at least in part on the HARQ-ACK information, wherein the PUCCH has an EPF; determine a PUCCH resource for the PUCCH and a first PRB index for the PUCCH, wherein the PUCCH resource is determined based at least in part on an index of a first Control Channel Element (CCE) of an associated Physical Downlink Control Channel (PDCCH) and a number of CCEs in a Control Resource Set (CORESET) of the associated PDCCH; and map the PUCCH to at least one PUCCH interlace based on the PUCCH resource and the first PRB index for the PUCCH.
