对于上述第一项,在频率f1上的载波X从时间单元S#0至时间单元S#6,每个时间单元内的4个RB set(RB set#0至RB set#3)的传输方向的配置和指示,如图3所示,根据索引最小的频域单元的传输方向,确定时间单元S#3的传输方向为D、确定时间单元S#4的传输方向为F、确定时间单元S#5的传输方向为F、确定时间单元S#6的传输方向为U。
对于上述第二项,参考频域单元可以是网络配置和/或指示的一个频域单元,例如,第K个RB set,K是N_bw中的最大或最小索引,或者,K是包含初始(initial)DL/UL BWP的RB set(s)的最小索引或最大索引或任一索引;
或者,所述参考频域单元是所述时间单元内,除去传输方向为F的RB set里确定的频域单元,例如,索引最大或索引最小的频域单元。
参考图3,假设参考频域单元为RB set#2,则确定时间单元S#3的传输方向为U、确定时间单元S#4的传输方向为U、确定时间单元S#5的传输方向为D、确定时间单元S#6的传输方向为U。假设参考频域单元为除去传输方向为F的RB set中索引最小的RB set,则确定时间单元S#3的传输方向为D、确定时间单元S#4的传输方向为D、确定时间单元S#5的传输方向为U、确定时间单元S#6的传输方向为U。
对于上述第三项:假设第一数值记为T_U、第二数值记为T_D,第三数 值记为T_F,则在T_D>T_U且T_D≥T_F时,确定时间单元的传输方向为D;在T_U>T_D且T_U≥T_F时,确定时间单元的传输方向为U;在T_F>T_D且T_F>T_U时,确定时间单元的传输方向为F;在T_D=T_U时,确定为错误的网络配置或指示,或者,终端自主确定传输方向。
参考图3,假设根据上述第一数值、第二数值和第三数值之间的关系来确定时间单元对应的传输方向,即根据最大数值对应的传输方向来确定时间单元对应的传输方向。例如,时间单元S#3中,T_D=2,T_F=1,T_U=1,所以传输方向为D;时间单元S#4中,T_D=2,T_F=1,T_U=1,所以传输方向为D;时间单元S#5中,T_D=1,T_F=1,T_U=2,所以传输方向为U;时间单元S#6中,T_D=1,T_F=0,T_U=3,所以传输方向为U。
对于上述第四项,对于上述表1中的组合1、组合2和组合4,可默认传输方向为U,对于上述表1中的组合3和组合4,可默认为F。
对于上述第七和第八项,参考图3,时间单元S#3的传输方向是通过终端特定DCI或公共DCI指示的D;对于时间单元S#4的传输方向是通过终端特定DCI或公共DCI指示的D;对于时间单元S#5的传输方向是通过终端特定DCI或公共DCI指示的F;对于时间单元S#6的传输方向是通过终端特定DCI或公共DCI指示的U。另外,若多个终端特定的动态信令或公共动态信令同时存在,则根据最新的动态信令确定传输方向。
对于上述第九项和第十项,假设根据信号的优先级来确定时间单元对应的传输方向,先确定目标载波X,再根据目标载波X上待处理的信号的优先级来确定时间单元对应的传输方向,假设第一优先级的下行数据/控制信息/参考信号>第二或第一优先级的上行数据/控制信息/参考信号,或者,第一优先级的上行数据/控制信息/参考信号>第二或第一优先级的下行数据/控制信息/参考信号,例如,SSB>PRACH>PDCCH>PUCCH>包含有上行控制信息(Uplink Control Information,UCI)的上行数据>PDSCH>不包含有上行控制信息(UCI)的上行数据。参考图3,时间单元S#3的RB set#2上待处理的信号为配置授权PUSCH,时间单元S#3的RB set#3上待处理的信号 为SSB,则确定时间单元S#3对应的传输方向D;时间单元S#4的RB set#2上待处理的信号为第一优先级的配置授权PUSCH,时间单元S#4的RB set#3上待处理的信号为第一优先级的PDSCH,则确定时间单元S#4对应的传输方向D;时间单元S#5的RB set#2上待处理的信号为第二优先级的PDSCH,时间单元S#5的RB set#3上待处理的信号为第一优先级的配置授权PUSCH,则确定时间单元S#5对应的传输方向U;时间单元S#6的RB set#2上待处理的信号为PDSCH,时间单元S#6的RB set#3上待处理的信号为PUCCH,则确定时间单元S#4对应的传输方向U。
或者,根据所有载波上待处理的信号的目标信息,确定时间单元对应的传输方向,参考图4,根据载波CC#0和载波CC#1上的时间单元S#3内的所有RB set待处理信号的优先级来确定时间单元S#3对应的传输方向,假设载波CC#0的时间单元S#3中的RB set#3上待处理的信号的传输优先级最高,则确定时间单元S#3对应的传输方向为D,其他时间单元的确定方法类似,此处不再赘述。

在所述时间单元内的任意两个频域单元根据第一指示信令确定的传输方向为第三预设组合传输方向的情况下,确定所述时间单元对应的传输方向为下行传输方向或灵活传输方向,其中,网络配置的第一符号与第二符号之间 的时间差大于或者等于终端处理时间;
