    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： Systems and methods for PDCCH monitoring in NR systems. The UE provides to a serving cell UE capability information indicating a capability of the UE to monitor PDCCH. The UE capability information indicates a carrier aggregation capability larger than multiple serving cells and has a maximum number indication for a maximum number of PDCCH candidates that the UE can monitor per span. The serving cell transmits an RRC message to a UE in response to the UE capacity information. The RRC message has a per-slot and/or per-span indication to monitor PDCCHs on the serving cell for a maximum number of PDCCH candidates and non-overlapping CCEs. The UE monitors PDCCH candidates and, in the event that a span contains larger than a maximum number of PDCCH candidates or non-overlapping CCEs across multiple served cells, determines whether to monitor a particular PDCCH candidate in the span.

    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.

    摘要翻译： 通常描述eNodeB（eNB），用户设备（UE）和使用减少的数据传输带宽进行操作的方法。 UE可以接收下行链路控制信息（DCI），该下行链路控制信息（DCI）为子帧的PRB中的通信提供小于1个PRB的减少的物理资源块（PRBmin）的资源分配（RA）。 无论RA是本地化的还是分布式的，可以通过系统信息块或无线电资源控制信令来配置，或以DCI格式表示。 DCI格式可以通过子载波块索引和子载波块的总数或对应于子载波或块索引的唯一块的位图来指定分配给UE的PRB内的资源。 单元无线电网络临时标识符（RNTI）列表中的顺序可以与公共RNTI一起使用以从1个PRB RA导出减少的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.
