    摘要： An enhanced NodeB (eNB), user equipment (UE) and method of Channel State Information (CSI) measurement and reporting using reduced bandwidth are generally described herein. The UE is preconfigured with a resource configuration information or the configuration information is transmitted to the UE from the eNB. The configuration information indicates a narrowband region on which to monitor for and receive physical downlink control and data channels and perform measurements for CSI computation. The region has a reduced bandwidth that is supported by the UE and is free from subbands outside of the region. The UE takes measurements of downlink transmissions using the assigned resources. The measurements are limited to subbands included within the region. The UE calculates the CSI based on an unrestricted time interval within subframes of the region and a restricted frequency interval free from physical resource blocks outside the region. The UE reports a region-specific wideband CSI that includes at least a region-specific wideband Channel Quality Indicator to the eNB.

    摘要： A generation Node B (gNB) configured for Sub-Band Full Duplex (SBFD) communication in a fifth-generation new radio (5G NR) network may communicate with two or more User Equipment (UEs) during SBFD symbols. During any one or more of the SBFD symbols, a downlink transmission may be transmitted to at least one of the UEs simultaneously with reception of an uplink transmission from at least another of the UEs. The SBFD symbols may span the carrier bandwidth and may comprise at least a downlink (DL) subband and an uplink (UL) subband within the carrier bandwidth. To communicate with the two or more UE simultaneously during the SBFD symbols, the gNB may configure the UEs that are to transmit during one or more of the SBFD symbols with timing-advance offset information to be used by the UEs to adjust a configured timing-advance for initiating an uplink transmission relative to downlink symbol timing at a UE within the one or more SBFD symbols. A timing-advance offset may delay an uplink transmission of during one or more of the SBFD symbols that follows a downlink symbol. This offset or delay, relative to the timing-advance, may provide a UL-DL switching time gap when the SBFD symbol follows a DL symbol.

    摘要： An eNodeB (eNB), user equipment (UE) and method for operating using a reduced data transmission bandwidth are generally described. The UE may receive downlink control information (DCI) that provides a resource allocation (RA) of a reduced physical resource block (PRBmin) of less than 1 PRB for communications in a PRB of a subframe. Whether the RA is localized or distributed may be predefined, configured via system information block or Radio Resource Control signaling, or indicated in the DCI format. The DCI format may specify the resources within the PRB allocated to the UE through a subcarrier block index and total number of subcarrier blocks or a bitmap corresponding to a unique block of subcarriers or block index. An order in a list of cell Radio Network Temporary Identifiers (RNTIs) may be used with a common RNTI to derive the reduced RA from a 1 PRB RA.

    摘要： A user equipment (UE) is capable of directly communicating with one or more other UEs using a 3rd Generation Partnership Project (3GPP) communication specification. The UE is configured to identify a gap size for a device-to-device communication. The UE is configured to identify a cyclic prefix length for the device-to-device communication and transmit the device-to-device communication comprising a subframe having a physical uplink shared channel (PUSCH) structure. The subframe has the identified cyclic prefix length, and one or more last symbols of the subframe include a gap having the identified gap size.
