Abstract

Description

一种资源管理方法及相关设备 技术领域
本发明涉及通信技术领域，具体涉及一种资源管理方法及相关设备。
背景技术
长期演进(Long Term Evolution，LTE)系统中，基站通过物理下行控制信道(Physical Downlink Control Channel，PDCCH)向用户终端(User Equipment，UE)发送调度信令，例如下行控制信息(Downlink Control Information，DCI)，为UE分配时频等资源，并调度UE的数据传输。现有的LTE系统帧结构为一个传输时间间隔(Transmission Time Interval，TTI)的长度等于一个子帧的长度，一个子帧包括14个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。
为了满足突发的、对时延要求很高的业务传输需求，引入了短TTI的概念，其长度被建议为1/2/3/4/7个OFDM符号，同时也要求短TTI的UE支持现有长度的TTI，这对于短TTI的UE而言，就涉及到在不同长度的TTI之间切换，如果采用物理层信令进行灵活地动态切换，则在同一时刻可能出现不同长度的TTI之间存在重叠的情况，例如长TTI在传输承载的数据时，有突发的短TTI与长TTI之间存在重叠，或者，不同长度TTI承载的数据的重传发生在同一时刻，导致长短TTI之间存在重叠。对于不同的UE之间，第一UE利用基站分配的资源进行数据传输，第二UE在传输突发的、对时延要求很高的业务时所需的短TTI可能会与第一UE占用的长TTI之间存在重叠，第一UE和第二UE之间会产生相互干扰。
高通(Qualcomm)公司在第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)的R1-160906中提到，如果UE在进行上行数据传输时出现不同长度TTI之间存在重叠，则将长TTI释放一部分，以传输短TTI承载的数据，然而上述解决方式只适用于同一UE的不同长度的TTI之间存在重叠的情况，在不同UE之间出现不同长度的TTI存在重叠时，UE之间不知道重叠的发生，会产生相互干扰，导致数据传输的可靠性降低。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全 部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，为本发明实施例提供的一种资源管理方法的第一实施例流程示意图。本实施例中所描述的资源管理方法主要是从UE一侧进行描述的，包括以下步骤：
S101、UE接收基站发送的资源释放信令，该资源释放信令指示了资源位置信息。
具体的，本发明实施例引入一种用于指示UE释放资源的资源释放信令，该资源释放信令相对于用于调度数据传输的调度信令(例如：DCI)进行了简化，可以只包括资源位置信息。该基站具体可以在确定出多个UE之间资源占用存在重叠的情况下，向一个或多个UE发送该资源释放信令，例如，第一UE正在利用网络侧分配的资源进行数据传输，第二UE有满足突发、业务优先级高、对时延要求高等中的至少一项的业务的数据需要传输，此时该网络侧给第二UE分配的资源可能与第一UE当前占用的资源有所重叠，则该基站可以向该第一UE发送该资源释放信令。
其中，该资源位置信息可以包括：时域位置信息、频域位置信息、载波指示、波束指示和码资源指示中的至少一种，该时域位置信息表示资源的时域大小，该频域位置信息表示资源的频域大小。该资源释放信令的生效时间可以与该调度信令的生效时间相同，可以维持现有的控制与数据传输之间的时序关系不变。
S102、该资源位置信息包括时域位置信息和频域位置信息，该UE根据该时域位置信息和该频域位置信息，分别从网络侧分配给该UE的已分配资源中确定该时域位置信息对应的目标时间，以及确定该频域位置信息对应的目标频率。
S103、该UE释放该目标时间和该目标频率组成的时频资源。
具体的，该资源位置信息可以包括时域位置信息和频域位置信息，即该基站可以根据其他UE所需的资源量指示该UE需要释放资源的时域大小和频域大小，该UE从已分配的资源中确定该时域位置信息和该频域位置信息对应的时频资源(即为需要释放资源)，该UE按需释放资源，可以提高资源利用率。
在一些可行的实施方式中，该资源位置信息可以只包括该时域位置信息，网络侧分配给该UE的已分配资源包括时间和频率，该UE根据该时域位置信息，从该已分配资源中确定该时域位置信息对应的目标时间，以及确定该目标时间内已分配给该UE的所有频率为目标频率，并释放该目标时间和该目标频率组成的时频资源。
具体的，该基站发送的该资源释放信令只指示需要释放资源的时域大小，此时该UE可以释放该时域位置信息对应的时域资源，同时释放该时域资源上分配给该UE的所有频域资源，该资源释放信令的进一步简化可以有效降低网络的信令负荷。
在一些可行的实施方式中，该资源位置信息可以只包括该频域位置信息，该UE根据预设时间长度和该频域位置信息，从网络侧分配给该UE的已分配资源中确定该预设时间长度的目标时间，以及确定该频域位置信息对应的目标频率，并释放该目标时间和该目标频率组成的时频资源。
具体的，该基站在该UE进行数据传输时，在向该UE发送资源释放信令之前，可以向该UE发送高层信令(例如：RRC信令)，通过该高层信令将该预设时间长度通知给该UE，或者，该UE与该基站之间的通信协议中也可以设定该预设时间长度，该UE可以直接根据该通信协议获取该预设时间长度而无需从该基站处获取。
可见，该基站发送的该资源释放信令只指示需要释放资源的频域大小，确定时域大小的该预设时间长度由该基站事先通知给该UE，或者，由该UE直接从与该基站之间的通信协议中获取，该资源释放信令的进一步简化可以有效降低网络的信令负荷。
在一些可行的实施方式中，该资源释放信令也可以不包括该资源位置信息，即不指示需要释放资源的时域大小和频域大小，该资源释放信令得到更进一步的简化，例如可以只有一个比特(bit)，该比特置1时表示该UE需要进行资源释放。
具体的，该基站在该UE进行数据传输时，在向该UE发送资源释放信令之前，可以向该UE发送高层信令(例如：RRC信令)，通过该高层信令将用于确定需要释放资源的时域大小的该预设时间长度通知给该UE，或者，该UE 与该基站之间的通信协议中也可以设定该预设时间长度，同时释放该时域大小的时域资源上分配给该UE的所有频域资源。
在一些可行的实施方式中，该时域位置信息和该预设时间长度具体可以包括OFDM符号个数、TTI的个数和TTI的长度中的至少一种，即该基站具体可以通过OFDM符号个数、TTI的个数和TTI的长度等参数指示该UE需要释放的资源的时域大小。该频域位置信息具体可以包括子载波的个数，用于指示该UE需要释放的资源的频域大小。
在一些可行的实施方式中，该资源位置信息还可以包括该载波指示，如果该UE同时利用多个载波与该基站之间进行数据传输，则该UE只在该载波指示所指示的载波上释放该时频资源。
在一些可行的实施方式中，该资源位置信息还可以包括该波束指示，如果该UE同时利用多个波束与该基站之间进行数据传输，则该UE只在该波束指示所指示的波束上释放该时频资源。
在一些可行的实施方式中，该资源位置信息还可以包括该码资源指示，如果该UE同时利用多个码道与该基站之间进行数据传输，则该UE只在该码资源指示所指示的码道上释放该时频资源。
在一些可行的实施方式中，该资源位置信息还可以包括该载波指示、该波束指示和该码资源指示中的至少两种参数，则该UE只在该至少两种参数共同确定的资源上释放该时频资源。
本发明实施例中，UE接收基站发送的资源释放信令，该资源释放信令指示了资源位置信息，并根据该资源位置信息，从网络侧分配给该UE的已分配资源中确定该资源位置信息对应的时频资源，进而释放该时频资源，UE可以根据基站的指示将已分配资源中的一部分释放，可以有效减少资源占用重叠带来的干扰，提高数据传输的可靠性。
请参阅图2，为本发明实施例提供的一种资源管理方法的第二实施例流程示意图。本实施例中所描述的资源管理方法主要是从UE一侧进行描述的，包括以下步骤：
S201、UE接收基站发送的资源释放信令，该资源释放信令指示了资源位 置信息。
S202、网络侧分配给该UE的已分配资源包括第一TTI，该UE从该第一TTI中确定该资源位置信息包括的时域位置信息对应的目标时间，或者该UE从该第一TTI中确定预设时间长度的该目标时间。
其中，该第一TTI可以是现有LTE系统规定的长TTI。该基站具体可以在确定出多个UE之间资源占用存在重叠的情况下，向一个或多个UE发送该资源释放信令，例如，第一UE正在利用网络侧分配的资源(例如：长TTI)进行数据传输，第二UE有满足突发、业务优先级高、对时延要求高等中的至少一项的业务的数据需要通过短TTI传输，此时该网络侧给第二UE分配的短TTI可能与第一UE当前占用的长TTI有所重叠，则该基站可以向该第一UE发送指示资源位置信息的资源释放信令，预设时间长度以及该资源位置信息包括的时域位置信息可以包括该短TTI对应的OFDM符号个数或TTI长度。
具体的，该UE根据该时域位置信息或该预设时间长度从该第一TTI中释放相应数量的OFDM符号或者相应长度的TTI。
S203、该UE在该目标时间内已分配给该UE的频率中确定该资源位置信息包括的频域位置信息对应的目标频率，或者该UE确定该目标时间内分配给该UE的所有频率为该目标频率。
S204、该UE释放该目标时间和该目标频率。
本发明实施例中，UE接收基站发送的资源释放信令，该资源释放信令指示了资源位置信息，网络侧分配给该UE的已分配资源包括长TTI，该UE从该长TTI中释放该资源位置信息包括的时域位置信息或该预设时间长度指示的相应数量的OFDM符号或者相应长度的TTI，并可以释放该长TTI内该资源位置信息包括的频域位置信息对应的频率或者分配给该UE的所有频率，UE可以根据基站的指示将已分配资源中的一部分释放，可以有效减少资源占用重叠带来的干扰，提高数据传输的可靠性。
请参阅图3，为本发明实施例提供的一种资源管理方法的第三实施例流程示意图。本实施例中所描述的资源管理方法主要是从UE一侧进行描述的，包括以下步骤：
其中，步骤S301～步骤S303可以参照上面实施例中的步骤S101～步骤S103，此处不再赘述。
S304、该网络侧分配给该UE的已分配资源包括K个bundling的TTI，该目标频率为K个bundling的TTI中目标TTI内已分配给该UE的频率的部分或全部，该UE对该目标TTI的被释放部分进行打孔处理，或者，在该目标TTI的未被释放部分上利用新的速率匹配参数发送或者接收该目标TTI承载的RV或数据块，或者，在该未被释放部分上利用新的传输块大小TBS发送或者接收该目标TTI承载的数据块。
其中，K为大于1的整数，TTI bundling是将多个TTI联合起来为一个UE做数据传输调度，可以用一个调度信令一次调度多个TTI，该K个bundling的TTI用于承载同一个数据块的K个冗余版本(Redundancy Version，RV)或K个数据块，进行bundling的TTI可以在时间上连续，也可以在时间上不连续，该目标TTI可以为一个TTI或多个TTI。
具体的，bundling的TTI与单个的TTI共存，该UE释放的该目标时间即为该目标TTI，该目标频率即为该目标TTI内已分配给该UE的频率的部分或全部。该UE对该目标TTI的被释放部分进行打孔处理，即在该被释放部分上，上行数据的发射功率为0，下行数据不接收。或者，该UE根据该目标TTI的未被释放部分和该目标TTI承载的RV或数据块，重新设定速率匹配参数，并利用新的速率匹配参数在该未被释放部分上发送或者接收该目标TTI承载的RV或数据块。或者，该UE根据该未被释放部分将该目标TTI承载的数据块重新分块，并利用新的传输块大小(Transport Block Size，TBS)对该目标TTI承载的数据块进行发送或者接收。
需要说明的是，如果该目标TTI内已分配给该UE的所有频率都被释放，则该UE在该目标TTI上不发送数据，也不接收数据。
S305、该UE在该目标TTI之后的下一个可用TTI上发送或者接收该目标TTI承载的RV或数据块。
具体的，如果该目标TTI承载的是同一个数据块的多个RV中最重要的RV(例如：RV 0)，则该UE可以在该目标TTI之后的下一个可用TTI上再次发送或者接收该目标TTI承载的RV，保证最重要的RV完整地传输一次， 可以提高数据传输的可靠性。
如果该目标TTI承载的是一数据块，则对于该目标TTI承载的数据块，该UE在该目标TTI之后的下一个可用TTI上可以选择发送或者接收。
在一些可行的实施方式中，对于该目标TTI承载的数据块，该UE在该目标TTI之后的下一个可用TTI上也可以选择不发送或者不接收。
S306、该UE在该K个bundling的TTI之后的下一个可用TTI上发送或者接收该K个RV中的最后一个RV或所述K个数据块中的最后一个数据块。
具体的，该UE可以从该网络侧分配的资源中再单独利用该K个bundling的TTI之后的下一个可用TTI传输最后一个RV或最后一个数据块，可以进一步地提高数据传输的可靠性。
本发明实施例中，UE接收基站发送的资源释放信令，该资源释放信令指示了资源位置信息，并根据该资源位置信息，从网络侧分配给该UE的已分配资源中确定该资源位置信息对应的时频资源，进而释放该时频资源；在TTI bundling的场景中，该UE对多个bundling的TTI中目标TTI的被释放部分进行打孔处理，或者，利用新的速率匹配参数在未被释放部分上发送或者接收该目标TTI承载的RV或数据块，或者，利用新的TBS在未被释放部分上发送或者接收该目标TTI承载的数据块，对于重要的RV或数据块，该UE可以在多个bundling的TTI中的下一个可用TTI上再次进行发送或者接收，还可以在多个bundling的TTI之后的下一个可用TTI上发送或者接收该K个RV中的最后一个RV或该K个数据块中的最后一个数据块，UE可以根据基站的指示将已分配资源中的一部分释放，并且在TTI bundling的场景中对承载的RV或数据块的后续传输进行调整，可以有效减少资源占用重叠带来的干扰，提高数据传输的可靠性。
请参阅图4，为本发明实施例提供的一种资源管理方法的第四实施例流程示意图。本实施例中所描述的资源管理方法主要是从UE一侧进行描述的，包括以下步骤：
其中，步骤S401～步骤S403可以参照上面实施例中的步骤S101～步骤S103，此处不再赘述。
S404、该网络侧分配给该UE的已分配资源包括半持续调度SPS资源，该目标频率为该SPS资源中目标TTI内已分配给该UE的频率的部分或全部，该UE对该目标TTI的被释放部分进行打孔处理，或者，在该目标TTI的未被释放部分上利用新的速率匹配参数发送或者接收该目标TTI承载的数据块，或者，在该未被释放部分上利用新的TBS发送或者接收该目标TTI承载的数据块。
其中，半持续调度(Semi-Persistent Scheduling，SPS)资源为基站通过高层信令(例如：RRC信令)配置给UE的周期性资源，UE可以在SPS资源上持续地进行发送或者接收，直到基站下发去激活的调度信令使得UE将SPS资源释放。
具体的，该UE释放的该目标时间即为该目标TTI，该目标频率即为该目标TTI内已分配给该UE的频率的部分或全部。该资源释放信令相对于去激活信令更加简化，该UE根据该基站发送的该资源释放信令即可释放SPS资源中目标TTI的部分或全部，该目标TTI具体可以包括一个或多个TTI。
进一步地，该UE对该目标TTI的被释放部分进行打孔处理，即在该被释放部分上，上行数据的发射功率为0，下行数据不接收。或者，该UE根据该目标TTI的未被释放部分和该目标TTI承载的数据块，重新设定速率匹配参数，并利用新的速率匹配参数在该未被释放部分上发送或者接收该目标TTI承载的数据块。或者，该UE根据该未被释放部分将该目标TTI承载的数据块重新分块，并利用新的TBS对该目标TTI承载的数据块进行发送或者接收。
需要说明的是，如果该目标TTI内已分配给该UE的所有频率都被释放，则该UE在该目标TTI上不发送数据，也不接收数据。
本发明实施例中，UE接收基站发送的资源释放信令，该资源释放信令指示了资源位置信息，并根据该资源位置信息，从网络侧分配给该UE的已分配资源中确定该资源位置信息对应的时频资源，进而释放该时频资源；在该UE分配有SPS资源的场景中，该UE对SPS资源中目标TTI的被释放部分进行打孔处理，或者，利用新的速率匹配参数在未被释放部分上发送或者接收该目标TTI承载的数据块，或者，利用新的TBS在未被释放部分上发送或者接收该目标TTI承载的数据块，可以有效减少资源占用重叠带来的干扰，提高数据 传输的可靠性。
请参阅图5，为本发明实施例提供的一种资源管理方法的第五实施例流程示意图。本实施例中所描述的资源管理方法主要是从基站一侧进行描述的，包括以下步骤：
S501、基站向至少一个UE发送指示资源位置信息的资源释放信令，该资源释放信令用于指示该至少一个UE根据该资源位置信息，从网络侧分配给该UE的已分配资源中确定与该资源位置信息对应的时频资源，并释放该时频资源。
具体的，该基站可以实时监测所覆盖的UE的业务传输情况，包括业务类型、业务优先级、业务的时延要求等，在确定出多个UE之间资源占用存在重叠的情况下，根据业务传输情况向一个或多个UE发送该资源释放信令，例如，第一UE正在利用网络侧分配的资源进行数据传输，第二UE有满足突发、业务优先级高、对时延要求高等中的至少一项的业务数据需要传输，此时该网络侧给第二UE分配的资源可能与第一UE当前占用的资源有所重叠，则该基站可以向该第一UE发送该资源释放信令。
需要说明的是，该基站在发送该资源释放信令时，会对该资源释放信令进行循环冗余码(Cyclic Redundancy Code，CRC)校验，并用一个无线网络临时标识(Radio Network Tempory Identity，RNTI)加扰，通过采用不同的RNTI可以改变该资源释放信令的生效对象，如果该资源释放信令是发送给一个UE的，则采用该UE专属的RNTI加扰，只有该UE可以解析出该资源释放信令；如果该资源释放信令是发送给一组UE的，则采用该组UE共用的RNTI加扰，从而该组UE包括的所有UE都可以解析出该资源释放信令。
本发明实施例中，基站向至少一个UE发送指示资源位置信息的资源释放信令，使得该至少一个UE可以根据该资源位置信息，从网络侧分配给该UE的已分配资源中确定与该资源位置信息对应的时频资源，并释放该时频资源，一个或多个UE可以根据基站的指示将已分配资源中的一部分释放，可以有效减少资源占用重叠带来的干扰，提高数据传输的可靠性。

具体的，该资源释放信令可以不包括该资源位置信息，即不指示需要释放资源的时域大小和频域大小，该资源释放信令得到更进一步的简化，例如可以只有一个比特(bit)，该比特置1时表示解析出该资源释放信令的UE需要进行资源释放。该基站在该至少一个UE进行数据传输时，在向该至少一个UE发送资源释放信令之前，可以向该至少一个UE发送高层信令(例如：RRC信令)，通过该高层信令将用于确定需要释放资源的时域大小的该预设时间长度通知给该至少一个UE，或者，该至少一个UE根据与该基站之间的通信协议获取该预设时间长度，同时释放该时域大小的时域资源上分配给该至少一个UE的所有频域资源。
