本发明涉及通信技术领域，尤其涉及一种数据接收、信息配置方法、终端及网络设备。
背景技术
现有技术中，数据丢失是数据传输过程中的常见现象。为了保证终端能够从网络设备接收到完整的数据，网络设备在初始传输数据之后，往往需要重传数据至终端。由此，终端在成功接收网络设备发送的数据之后，往往还要接收相同的重传数据，从而增加终端额外的耗电，造成耗电量大。
发明内容
本发明实施例提供一种数据接收、信息配置方法、终端及网络设备，以解决现有数据接收方法的耗电量大的问题。
为了解决上述技术问题，本发明实施例是这样实现的：

具体实施方式
为了更清楚地说明本发明实施例的技术方案，下面将对本发明实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本发明实施例无线通信系统包括终端和网络设备。其中，终端也可以称作终端设备或者用户设备(User Equipment，UE)，终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本发明实施例中并不限定终端的具体类型。网络设备可以是基站或核心网，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，不限于特定技术词汇。
需指出的，本发明实施例可适用于多媒体广播多播业务(Multimedia Broadcast and Multicast Service，MBMS)或广播多播业务(Multicast Broadcast Service，MBS)场景。对于MBMS或MBS场景，相应的信息发送方式可包 括但不限于如下两种：
发送方式1：在MBMS单频网(Multimedia Broadcast multicast service Single Frequency Network，MBSFN)子帧中通过物理多播信道(Physical Multicast Channel，PMCH)发送。其中，控制信息可以通过系统信息(如，SIB13)和广播控制信道(Multicast Control Channel，MCCH)发送，数据可以通过广播业务信道(Multicast Traffic Channel，MTCH)发送。
发送方式2：通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)发送。其中，控制信息可以通过系统信息(如，SIB20)和单小区广播控制信道(Single Cell Multicast Control Channel，SC-MCCH)发送，数据可以通过单小区广播业务信道(Single Cell Multicast Traffic Channel，SC-MTCH)发送。SC-MCCH可以通过单小区无线网络临时标识(Single Cell Radio Network Temporary Identity，SC-RNTI(Radio Network Temporary Identity，RNTI))PDCCH调度的PDSCH发送，SC-MTCH可以通过组RNTI(Group RNTI，G-RNTI)PDCCH调度的PDSCH发送。
对于接收的MBS数据，UE会提供上行反馈信息(比如，混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)确认/不确认(ACK/NACK)反馈信息)。而网络设备可根据该HARQ反馈信息决定是否调度重传。
请参见图1，图1是本发明实施例提供的一种数据接收方法的流程图，该方法应用于终端，如图1所示，该方法包括如下步骤：
步骤101：在成功接收第一数据之后，放弃第一数据的重传数据的接收。
本实施例中，第一数据可为MBMS数据或者MBS数据。对于MBMS数据或者MBS数据的接收，通常需要多个UE提供反馈信息，此时可能有的UE接收数据成功了，有的UE没有接收成功。网络设备根据UE的反馈信息，如果没有接收成功的UE的数量比较多，则会对该MBMS数据或者MBS数据进行重传。现有技术中对于成功接收数据的UE，即使该MBMS数据或者MBS数据已经成功接收了，依然要接收重传数据，从而增加UE额外的耗电，造成耗电量大。而基于本实施例，成功接收数据的UE会放弃对重传数据的接收，从而节省耗电，减少耗电量。
可选的，第一数据可与HARQ进程对应，比如为第一HARQ进程的数据。上述步骤101可包括：终端在成功接收第一HARQ进程的数据之后，放弃该第一HARQ进程的重传数据的接收。
可选的，上述重传数据的发送方式可以是特定标识(比如，C-RNTI、G-RNTI，或CS-RNTI)对应的重传数据发送。
可理解的，终端在成功接收第一数据之后，仍然可能会接收第一数据的重传信息，该重传信息比如为重传调度信息或者重传数据。上述放弃第一数据的重传数据的接收的方式可为：在接收到第一数据的重传调度信息的情况下，放弃接收该第一数据的重传数据；或者，在接收到第一数据的重传数据的情况下，丢弃接收到的该第一数据的重传数据。
比如，终端在成功接收第一数据之后，若在控制信道上接收到了该第一数据的重传调度信息，则放弃在相应调度的下行信道上接收该第一数据的重传数据；或者，若直接在调度的下行信道上接收该第一数据的重传数据，则丢弃该第一数据的重传数据。
本发明实施例的数据接收方法，终端在成功接收第一数据之后，可以放弃该第一数据的重传数据的接收。由此，可以使得数据接收成功的终端不再接收相同的重传数据，从而节省终端的耗电，减少耗电量。
本发明实施例中，根据网络配置或协议约定，终端在成功接收第一数据之后，可以基于如下任意一种方式来确定放弃重传数据的接收：
方式一
此方式一下，终端在成功接收第一数据之后，清空该第一数据的缓存数据。上述放弃第一数据的重传数据的接收具体为：基于该第一数据的缓存数据为空，放弃该第一数据的重传数据的接收。
作为一种可选的实施方式，UE在成功接收第一HARQ进程的数据(比如，该第一HARQ进程中的媒体接入控制(Media Access Control，MAC)协议数据单元(Protocol Data Unit，PDU)解码成功)之后，可清空该第一HARQ进程的缓存数据；对于后续接收到该第一HARQ进程的重传信息的情况，基于该第一HARQ进程的缓存数据为空，则放弃该第一HARQ进程的重传数据的接收。
一种实施方式中，UE可根据网络设备的配置进行数据的接收，比如，UE通过G-RNTI PDCCH调度的PDSCH接收HARQ进程的数据。若UE成功接收了HARQ进程的数据，则对于接收成功的数据对应的缓存数据，UE可清空该缓存数据，并对于后续的重传数据，基于该缓存数据为空，放弃该重传数据的接收。
例1.1：UE1-1在t1时刻接收到通过G-RNTI PDCCH调度PDSCH的数据，该数据的缓存对应HARQ进程1；如果UE1-1的HARQ进程1的该数据接收成功，则UE1-1清空该HARQ进程1对应的缓存。UE1-1在t2时刻又接收到通过G-RNTI或C-RNTI PDCCH调度的PDSCH的数据，该数据为HARQ进程1数据的重传数据，此时UE1-1判断HARQ进程1的缓存数据为空，则UE1-1丢弃接收到的该G-RNTI或C-RNTI PDCCH调度的PDSCH的数据。而如果UE1-1判断HARQ进程1的缓存数据不为空，则UE1-1继续接收该G-RNTI或C-RNTI PDCCH调度的PDSCH的数据，并将该重传数据与之前HARQ进程1中缓存的数据进行合并解码。
例1.2：UE1-2根据网络侧配置在半持续的下行资源(如，每10ms接收1个PDSCH)进行数据的接收。假设UE1-2在t3时刻成功接收到PDSCH数据，该数据对应的缓存为HARQ进程2，则UE1-2清空该HARQ进程2对应的缓存。如果，UE1-2在t3+5ms的时刻接收到了G-RNTI或C-RNTI调度的PDSCH的数据，该数据为HARQ进程2数据的重传数据，此时UE1-2判断的HARQ进程2的缓存数据为空，则UE1-2放弃该G-RNTI或C-RNTI PDCCH调度的PDSCH的数据接收。
例1.3：网络设备配置UE1-3在2个相邻的时隙(slot)接收相同的数据(比如，slot-1是新传数据采用rv0，slot-2是重传数据采用rv2)，对应相同的HARQ进程3。如果UE1-3在slot-1的数据接收成功，则可清空该HARQ进程3对应的缓存。进一步的，UE1-3在slot-2判断该HARQ进程3的缓存数据为空后，可放弃slot-2的PDSCH的数据接收。
方式二
此方式二下，终端在成功接收第一数据之后，添加标记信息；其中，该标记信息用于指示已成功接收第一数据，该标记信息的添加位置可以基于实 际需求选择，比如将标记信息添加于数据缓存区。上述放弃第一数据的重传数据的接收具体为：基于该标记信息，放弃该第一数据的重传数据的接收。
作为一种可选的实施方式，UE在成功接收第一HARQ进程的数据(比如，该第一HARQ进程中的MAC PDU解码成功)之后，可以在预设位置添加用于指示已成功接收第一数据的标记信息；对于后续接收到该第一HARQ进程的重传信息的情况，基于该标记信息，则放弃该第一HARQ进程的重传数据的接收。
一种实施方式中，UE根据网络设备的配置进行数据的接收，比如，UE通过G-RNTI PDCCH调度的PDSCH接收HARQ进程的数据。若UE成功接收了HARQ进程的数据，则可在预设位置添加用于指示已成功接收数据的标记信息，并对于后续重传数据，基于该标记信息，放弃该重传数据的接收。
例2.1：UE2-1在t4时刻接收到通过G-RNTI PDCCH调度PDSCH的数据，该数据的缓存对应HARQ进程4；如果UE2-1的HARQ进程4的该数据接收成功，则UE2-1在预设位置添加用于指示已成功接收数据的标记信息。UE2-1在t5时刻又接收到通过G-RNTI或C-RNTI PDCCH调度的PDSCH的数据，该数据为HARQ进程4数据的重传数据，则UE2-1基于该标记信息，丢弃接收到的该G-RNTI或C-RNTI PDCCH调度的PDSCH的数据。如果，UE2-1没有获得标记信息，并判断HARQ进程4的缓存数据没接收成功，则UE2-1继续接收该G-RNTI或C-RNTI PDCCH调度的PDSCH的数据，并将该重传数据与之前HARQ进程4中缓存的数据进行合并解码。
例2.2：UE2-2根据网络侧配置在半持续的下行资源(如，每10ms接收1个PDSCH)进行数据的接收。假设UE2-2在t6时刻成功接收到PDSCH数据，该数据对应的缓存为HARQ进程5，则UE2-2在预设位置添加用于指示已成功接收数据的标记信息。如果，UE2-2在t6+5ms的时刻接收到了G-RNTI或C-RNTI调度的PDSCH的数据，该数据为HARQ进程5数据的重传数据，此时UE2-2基于该标记信息，放弃该G-RNTI或C-RNTI PDCCH调度的PDSCH的数据接收。
例2.3：网络设备配置UE2-3在2个相邻的时隙(slot)接收相同的数据(比如，slot-3是新传数据采用rv0，slot-4是重传数据采用rv2)，对应相同 的HARQ进程6。如果UE2-3在slot-3的数据接收成功，则放弃slot-4的PDSCH的数据接收。
本发明实施例中，上述成功接收第一数据可包括以下任意一项：
本次数据接收后，独立解码成功(比如，本次数据为HARQ进程1的新传数据，UE对于HARQ进程1的新传数据解码成功)；
本次接收的数据与本次之前缓存的相同数据合并后解码成功(比如，本次接收的数据为HARQ进程1的重传数据，UE对于HARQ进程1的重传数据与HARQ进程1的缓存数据合并后解码成功)。
可选的，上述第一数据的发送方式可包括以下任意一项：
动态调度的数据发送方式(比如，C-RNTI或G-RNTI PDCCH调度的PDSCH的数据发送)；
半持续的数据发送方式(比如，半静态调度(Semi-Persistent Scheduling，SPS)的PDSCH的发送)。
本发明实施例中，根据网络配置或者协议约定，终端在接收第一数据(比如MBS数据)之后，需向网络设备发送反馈信息。而对于放弃的第一数据的重传数据，可根据网络配置或者协议约定，放弃该重传数据(比如，UE放弃接收的重传数据的PDSCH)对应的反馈信息的发送。
可选的，上述放弃第一数据的重传数据的接收之后，所述方法还包括：放弃该重传数据对应的反馈信息的发送；其中，该反馈信息的类型可为以下任意一种：HARQ反馈、信道状态信息(Channel State Information，CSI)反馈。
一种实施方式中，在该反馈信息的类型为HARQ反馈的情况下，对应放弃的反馈信息可为以下任意一种：
HARQ成功接收的反馈信息；比如，对于HARQ ACK反馈不发送，而对于HARQ NACK反馈需要发送；
HARQ没有成功接收的反馈信息；比如，对于HARQ NACK反馈不发送，而对于HARQ ACK反馈需要发送。
另一种实施方式中，在该反馈信息的类型为CSI反馈的情况下，对应放弃的反馈信息可为以下任意一种：
周期性CSI反馈；比如，对于周期性CSI反馈不发送，而对于非周期性CSI反馈需要发送；
非周期性CSI反馈；比如，对于非周期性CSI反馈不发送，而对于周期性CSI反馈需要发送。
