    Abstract: A grant-free transmission mode may be used to communicate small traffic transmissions to reduce overhead and latency. The grant-free transmission mode may be used in downlink and uplink data channels of a wireless network. In the downlink channel, a base station transmits packets to a group of UEs in a search space without communicating any transmission code assignments to the UEs. The UEs receive the downlink packets using blind detection. In the uplink channel, UEs transmit packets in an access space using assigned access codes which are either independently derived by the UEs or otherwise communicated by the base station using a slow-signaling channel. Hence, the grant-free transmission mode allows mobile devices to make small traffic transmissions without waiting for uplink grant requests.

    Abstract translation: 可以使用免授权传输模式来传送小的业务传输以减少开销和延迟。 无授权传输模式可用于无线网络的下行链路和上行链路数据信道。 在下行链路信道中，基站向搜索空间中的一组UE发送分组，而不向UE通信任何传输码分配。 UE使用盲检测接收下行链路分组。 在上行链路信道中，UE使用分配的接入码来发送接入空间中的分组，所述分配的接入码由UE单独导出，或者由基站使用慢信令信道进行通信。 因此，免授权传输模式允许移动设备在不等待上行链路授权请求的情况下进行小的业务传输。
