用于针对缩短的TTI确定HARQ-ACK传输定时的系统和方法
Abstract:
本发明描述了一种用户设备(UE)。所述UE包括处理器以及与所述处理器进行电子通信的存储器。存储在存储器中的指令可执行以配置服务小区中的长时隙的缩短的传输时间间隔(S-TTI)，所述长时隙的S-TTI用于服务小区中的物理下行链路共享信道(PDSCH)接收。这些指令也可执行以确定对服务小区的PDSCH混合自动重传请求确认/非确认(HARQ-ACK)发送定时，所述PDSCH HARQ-ACK发送定时是基于针对长时隙的S-TTI预定义的下行链路(DL)关联集确定的。这些指令可进一步执行以基于PDSCH HARQ-ACK发送定时使用长时隙的S-TTI来发送PDSCH HARQ-ACK信息。
Abstract(English):

A user equipment (UE) is described. The UE includes a processor and memory in electronic communication with the processor. Instructions stored in the memory are executable to configure a slot-long shortened transmission time interval (S-TTI) in a serving cell, the slot-long S-TTI being used for physical downlink shared channel (PDSCH) reception in the serving cell. The instructions are also executable to determine PDSCH Hybrid Automatic Repeat Request Acknowledgement/Negative Acknowledgement (HARQ-ACK) transmission timing for the serving cell, the PDSCH HARQ-ACK transmission timing being determined based on a downlink (DL) association set pre-defined for the slot-long S-TTI. The instructions are further executable to send PDSCH HARQ-ACK information using the slot-long S-TTI, based on the PDSCH HARQ-ACK transmission timing.
