上行的数据调度可以是网络通过config grant半静态配置的,也可以是网络通过DCI信令动态调度的。Config grant的半静态配置又可以分为config grant type1和config grant type2。这两种config grant的传输周期都是通过无线资源控制(Radio Resource Control,RRC)信令中的信元—ConfiguredGrantConfig来半静态配置的。不同的是,config grant type1的时频域资源及调制与编码策略(Modulation and Coding Scheme,MCS)等参数是由RRC信令在ConfiguredGrantConfig中一起配置给终端设备的,而config grant type2的时频域资源则是由激活该config grant的物理下行控制信道(Physical Downlink Control Channel,PDCCH)指示的。Uplink data scheduling can be semi-statically configured by the network through config grant, or dynamically scheduled by the network through DCI signaling. The semi-static configuration of Config grant can be divided into config grant type1 and config grant type2. The transmission periods of these two kinds of config grants are configured semi-statically through the information element in the radio resource control (Radio Resource Control, RRC) signaling—ConfiguredGrantConfig. The difference is that the time-frequency domain resource of config grant type1 and the modulation and coding scheme (Modulation and Coding Scheme, MCS) are configured to the terminal device by RRC signaling together in ConfiguredGrantConfig, while the time-frequency domain of config grant type2 The resource is indicated by the Physical Downlink Control Channel (PDCCH) that activates the config grant.
NR Rel-15规定,config grant的数据在进行重传时仍使用该config grant的资源。在R16中,config grant的数据重传存在两种资源的选择,一种是网络侧通过动态调度的方式来调度重传的数据,另外一种则是在该config grant的可用资源上进行数据的重传。此时需要有一个统一的规则来确定终端设备应该选择哪个资源来进行数据的重传。为此,提出了本申请实施例的以下技术方案。NR Rel-15 stipulates that the config grant data still uses the config grant resource when retransmission. In R16, there are two resource options for config grant data retransmission. One is to schedule the retransmitted data through dynamic scheduling on the network side, and the other is to perform data on the available resources of the config grant. Retransmission. At this time, a unified rule is needed to determine which resource the terminal device should select for data retransmission. To this end, the following technical solutions of the embodiments of the present application are proposed.

The following Table 1 shows the Information Element (IE) of the ConfiguredGrantConfig. In this IE, there is one The configuration of the period (periodicty) is used to indicate the period of the physical uplink shared channel (PUSCH) resource pre-configured by the network. It can be seen that the value of the period can be at least 2 symbols (symbol). It should be noted that the PUSCH resources pre-configured by the network may also be referred to as CG resources.
