示例性的,上述的第一预定规则可以是预定义的(如,协议规定的),或者,可以是网络设备为终端配置的。
示例2(PUSCH传输间跳频):如图4所示,在一个slot内,终端重复传输了4次PUSCH,由于第一次传输的PUSCH的时频资源为网络设备指示的,因此,终端对除第一次以外的其他三次PUSCH传输进行跳频,即终端在跳频点1(在第二次PUSCH传输的起始位置)、跳频点2(在第三次PUSCH传输的起始位置)以及跳频点3(在第四次PUSCH传输的起始位置)对PUSCH进行跳频。
示例3(PUSCH传输内跳频):如图5所示,在一个slot内,终端重复传输了4次PUSCH。其中,第一次传输的PUSCH的时频资源为网络设备指示的,终端对每一次传输内都进行跳频,对每一次传输之间不进行跳频。即终端在跳频点1(在第一次PUSCH传输的时域中间或近似中间位置)、跳频点2(在第二次PUSCH传输的时域中间或近似中间位置)、跳频点3(在第三次PUSCH传输的时域中间或近似中间位置)以及跳频点4(在第四次PUSCH传输的时域中间或近似中间位置)对PUSCH进行跳频,如图5所示,终端会在每次PUSCH传输内进行跳频。
示例性的,当第一信息包括终端在第一时间单元内第一次PUSCH传输的起始传输位置时,终端可以根据第一次传输PUSCH的起始传输位置在第一时间单元内的位置,确定第一时间单元内的跳频点。具体的,网络设备可以配置用于重复传输PUSCH的全部时域资源的近似一半的位置(floor(传输时间/2)或ceil(传输时间/2)),或者,slot边界,或者,slot的近似一半的位置作为默认的跳频点(例如,一个slot由14个OFDM符号构成,该slot的一半,即第7个OFDM符号与第8个OFDM符号的中间位置作为默认的跳频点)。
例如,以第一时间单元为slot为例,若第一次传输PUSCH的起始传输位置位于一个slot的前半部分,则可以将该slot内中心或近似一半的位置作为跳频点。
示例4:如图6所示,在一个slot内,当第一次PUSCH传输的初始OFDM符号为该slot内的第4个OFDM符号,且该slot内用于传输PUSCH的时域资源的范围为:第四个OFDM符号至第11个OFDM符号,此时,终端可以将第7个OFDM符号与第8个OFDM符号的中间位置作为跳频点,即图6中的跳频点1。
例如,以第一时间单元为slot为例,若第一次PUSCH传输的起始传输位置位于一个slot的后半部分,则可以将该slot的边界作为跳频点。
示例性的,当第一信息包括重复传输该PUSCH的传输次数时,终端可以根据该传输次数,来确定第一时间单元内的跳频点。例如,终端可以根据公式(跳频点位置根据floor(传输次数/2)或ceil(传输次数/2))确定跳频点,然后进行跳频,如,如果一次PUSCH重复传输持续4次,那么跳频点为第二次传输之后。
本发明实施例提供的PUSCH重复传输时的跳频方法,终端在重复传输PUSCH的过程中,可以直接根据第一信息在第一时间单元内的跳频点对PUSCH进行跳频,从而使得终端能够URLLC业务的PUSCH的重复传输过程中实现准确、有效的跳频,获得分集增益,提高通信效率、效能以及可靠性。
