Title
(EN) UPLINK SCHEDULING FOR LICENSE ASSISTED ACCESS
(ZH) 用于有执照辅助式接入的上行链路调度
Abstract
(EN)
Uplink scheduling for license assisted access (LAA) mode systems is discussed in which a base station transmits a conditional grant to served user equipment (UE) that include a transmission configuration for uplink transmissions. The transmission configuration includes the parameters necessary for the UE to perform transmissions. Before the beginning of an uplink transmission opportunity, a base station transmits an uplink activation grant over a contention-based shared carrier to the served UE. The uplink activation grant indicates the transmission opportunity to the UE and may identify a subset of UE out of the served UE that are available for transmission. The base station first secures the channel before transmitting the uplink activation grant. Upon receipt of the uplink activation grant, the UE determines whether they will perform uplink transmissions and, if so, transmit the uplink data according to the transmission configuration.

讨论了用于有执照辅助式接入(LAA)模式系统的上行链路调度,其中基站向所服务的用户装备(UE)传送包括用于上行链路传输的传输配置的有条件准予。传输配置包括UE执行传输所必需的参数。在上行链路传输机会开始之前,基站通过基于争用的共享载波向所服务的UE传送上行链路激活准予。上行链路激活准予向UE指示传输机会并且可以从所服务的UE中标识可用于传输的UE子集。基站在传送上行链路激活准予之前首先取得信道。在接收到上行链路激活准予之际,UE确定它们是否将执行上行链路传输,并且如果是,则根据传输配置来传送上行链路数据。
