    • The present invention discloses a downlink control information sending method and device, and a downlink control information receiving method and device. The sending method includes: sending, by a base station device, downlink control information DCI on a physical downlink control channel PDCCH of a downlink subframe, where the DCI is used to instruct user equipment UE to receive physical downlink shared channel PDSCH information in an uplink subframe; and sending the PDSCH information in the uplink subframe. In this way, the base station can effectively schedule an uplink subframe, and a purpose of transmitting a downlink service by using an uplink subframe is achieved, which not only improves utilization of a wireless spectrum resource corresponding to the uplink subframe, but also effectively diverts load pressure of a wireless spectrum resource corresponding to a downlink subframe. Therefore, overall utilization of wireless spectrum resources of a system is improved.
    • 本发明公开了一种下行控制信息发送方法和设备,以及一种下行控制信息接收方法和设备。 该发送方法包括:基站设备在下行子帧的物理下行控制信道PDCCH上发送下行控制信息DCI,该DCI用于指示用户设备UE在上行中接收物理下行共享信道PDSCH信息 子帧; 并在上行子帧上发送PDSCH信息。 这样,基站可以有效调度上行子帧,达到了利用上行子帧传输下行业务的目的,不仅提高了上行子帧对应的无线频谱资源的利用率,而且有效地转移了 加载下行子帧对应的无线频谱资源的压力。 因此,系统的无线频谱资源的整体利用率得到提高。

    • A method and apparatus are disclosed for a relay UE to receive packets from an eNB where the relay UE acts as a relay for forwarding the packets between a remote UE and the eNB. The method includes the relay UE connecting with the eNB (2005). The method further includes the relay UE being configured with a radio bearer between the relay UE and the eNB (2010). The method also includes the relay UE receiving a downlink packet on the radio bearer from the eNB, wherein the downlink packet is to be transmitted to the remote UE (2015). In addition, the method includes the relay UE not transmitting any resource request to the eNB for requesting a SL grant for transmission of a sidelink packet including the downlink packet when the sidelink packet becomes available for transmission and there is currently no data available for transmission to the remote UE (2020). Furthermore, the method includes the relay UE receiving the SL grant from the eNB (2025). Also, the method includes the relay UE using the SL grant to transmit the sidelink packet to the remote UE (2025).
    • 公开了一种用于中继UE从eNB接收分组的方法和装置,其中中继UE充当用于在远程UE和eNB之间转发分组的中继。 该方法包括与eNB连接的中继UE(2005)。 该方法还包括中继UE配置在中继UE与eNB之间的无线承载(2010)。 该方法还包括中继UE从eNB接收到的无线承载上的下行链路分组,其中下行链路分组将被发送到远程UE(2015)。 此外,该方法包括:中继UE在边缘分组变得可用于传输时,不向eNB发送任何资源请求,用于请求用于发送包括下行链路分组的边界分组的SL授权,并且当前没有可用于传输的数据 远程UE(2020)。 此外,该方法包括从eNB接收SL许可的中继UE(2025)。 此外,该方法包括使用SL许可的中继UE向远程UE发送侧链包(2025)。
