Title
(EN) Improved re-transmission capability in semi-persistent transmission
(ZH) 在半持续性传输中改善的重传能力
Abstract
(EN)
One or more hybrid automatic repeat request process identifications are configured for scheduling without associated control signaling. A particular HARQ process ID to be assumed for a given subframe is determined based on at least one of: a) system frame number; b) number of hybrid automatic repeat request processes that are allocated for semi- persistent scheduling; and c) periodicity for semi-persistent scheduling. In various embodiments: a) is broadcast and b) and c) are sent via RRC signaling; and the assumed particular HARQ process ID is determined as a function of [Current TTI/SP_Period] mod Num_SP_HARQ: wherein Current TTI is a number for the given subframe derived from the system frame number and the term [Current TTI/SP_Period] is rounded to an integer prior to the modulo operation; SP_Period is the periodicity of the semi-persistent scheduling; and Num_SP_HARQ is the number of hybrid automatic repeat request processes that are allocated for semi-persistent scheduling.

一个或多个混合自动重传请求过程标识被配置为用于无需关联控制信令而进行调度。被设定为用于给定子帧的一个特定HARQ过程ID是基于以下至少一项而确定的:a)系统帧号;b)为半持续性调度分配的混合自动重传请求过程的数目;以及c)半持续性调度的周期性。在各种实施方式中,a)是广播的,并且b)和c)是经由RRC信令发送的;以及根据[Current TTI/SP_Period]modNum_SP_HARQ来确定该设定的特定HARQ过程ID:其中CurrentTTI是从系统帧号中导出的给定子帧号,并且项[CurrentTTI/SP_Period]在取模运算之前被舍入到整数;SP_Period是半持续性调度的周期性;以及Num_SP_HARQ是为半持续性调度分配的混合自动重传请求过程的数目。
