Abstract

本发明公开了一种应答信息处理方法，包括：网络设备判断用户设备是否发送目标数据对应的应答信息，得到判断结果；向所述用户设备发送携带所述判断结果的指示信令；所述用户设备基于网络设备发送的指示信令，确定是否发送目标数据对应的应答信息。本发明还公开了另一种应答信息处理方法、网络设备、用户设备及存储介质。

Description

一种应答信息处理方法、设备及存储介质 技术领域
本发明涉及无线通信技术领域，尤其涉及一种应答信息处理方法、设备及存储介质。
背景技术
第五代(5 th Generation，5G)新无线(New Radio，NR)系统中，用户设备(User Equipment，UE)传输针对数据的确认(Acknowledge，ACK)或不确认(Non-Acknowledge，NACK)应答信息的传输时间，可以由5G基站(g NodeB，gNB)动态指示。举例来说，gNB在时隙(slot)n中调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输，并且在调度该PDSCH的下行链路许可(Down Link grant，DL grant)中指示传输时间k1；UE根据gNB的指示在slot(n+k1)中传输该PDSCH对应的ACK/NACK应答信息。
另外，5G NR系统支持对时延敏感的高可靠通信(Ultra Reliable&Low Latency Communication，URLLC)业务；在时分双工(Time Division Duplexing，TDD)系统中，由于上下行资源通过时分的方式复用，因此确定UE传输PDSCH的应答信息的时间时，不仅要考虑数据处理时延，而且要考虑可用的上行资源位置。因此，在使用TDD系统传输URLL C业务时，某些时刻中传输的PDSCH对应的最早的可传输上行反馈时间资源，已经超出了业务时延需求；此时，UE继续传输对应的ACK/NACK应答信息，不仅浪费UE的功耗及5G NR系统中的上行控制信道开销，而且可能导致上行控制信道与5G NR系统中的其他信道的碰撞。
发明内容

所述处理器用于运行所述计算机程序时，执行：基于网络设备发送的指示信令，确定是否发送目标数据对应的应答信息。

或实现判断UE是否发送目标数据对应的应答信息，得到判断结果；向所述UE发送携带所述判断结果的指示信令。
本发明实施例提供的应答信息处理方法、设备和存储介质，通过网络设备预先判断是否需要UE发送目标数据对应的应答信息，并且将判断结果携带在指示信令中发送至UE，使得UE能够根据网络设备的指示发送或者不发送目标数据对应的应答信息。如此，避免了UE在不需要传输目标数据对应的应答信息时，继续传输目标数据对应的应答信息；不仅节省了UE的功耗及5G NR系统中的上行控制信道开销，而且能够避免上行控制信道与5G NR系统中的其他信道的碰撞。

举例来说，在UE判断第一信息域的取值为0时，不发送目标数据对应的应答信息；在UE判断第一信息域的取值为1时，发送目标数据对应的应 答信息。这里，仅是以第一信息域的取值为0和1作为示例；在实际应用中，可以设定第一信息域的取值为除0和1以外的其它数值，用于指示发送或不发送目标数据对应的应答信息。

举例来说，目标数据在节点(slot)n中传输，目标数据对应的应答信息在slot(n+k1)中传输，如图4所示的第二信息域的值与目标数据对应的应答信息的传输时间之间的对应关系(第一映射关系)，第二信息域由3比特组成，可以指示最多8个传输时间值，当网络设备通过第二信息域指示的传输时间为∞时，表征UE不发送目标数据对应的应答信息。这里，所述第一映射关系有网络设备配置或者由协议约定。
再一实施例中，所述第二信息域用于指示目标数据对应的应答信息的传输时间；当所述传输时间小于或等于第四阈值时，确定在所述第二信息域中指示的应答信息的传输时间内发送所述目标数据对应的应答信 息。

在一实施例中，为了提高5G NR系统的稳定性，网络设备在每次调度下行目标数据时，动态调整调制与编码策略(Modulation and Coding Scheme，MCS)等信息，使得网络设备单次传输的信息不完全相同。
举例来说，对于在较早时刻(距离时延上行较远的时刻)调度的PDSCH基于99％的目标块差错率(Block Error Ratio，BLER)确定MCS，通过重传来满足99.999％的正确率，从而提高5G NR系统的效率。但是，对于在较晚时刻(距离时延上行较近的时刻)调度的PDSCH基于99.999％的目标BLER确定MCS时，不需要对该PDSCH进行HARQ重传，因此UE也不需要传输目标数据对应的应答信息。
步骤S502，网络设备向所述UE发送携带所述判断结果的指示信令。

在一可选实施方式中，预先设定第二信息域的值与目标数据对应的应答信息的传输时间之间的对应关系(第一映射关系)，以使UE根据第 二信息域的值和第一映射关系确定是否发送目标数据对应的应答信息。
本发明实施例中，所述第一阈值、第二阈值、第三阈值、第四阈值、第五阈值的取值以及第一映射关系均可由所述网络设备配置或由协议约定；所述网络设备的功能可由基站实现。

或者，指示所述UE不发送所述目标数据对应的应答信息时，所述指示信令用于指示其他信息，如：资源部分指示信息中的BWP indicator，用于指示传输目标数据的BWP以实现动态切换BWP；Transmission configuration indication；Antenna port(s)；ZP CSI-RS trigger；SRS request；DMRS sequence initialization等。
在另一实施方式中，在所述指示信令指示所述UE发送所述目标数据对应的应答信息时，所述第三信息域用于指示与传输应答信息相关的信息。
