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，所描述的实施例是本发明的一部分实施例，而不是全部实施例。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的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
图1示出了根据本发明实施例的无线资源分配的方法100的示意性流程图，该方法100可以由发送端执行，该发送端可以为基站；或者对于终端对终端的直接通信场景，该发送端为两个终端其中发送端设备。如图1所示，该方法100包括：
S110，发送端根据接收端在当前状态下的身份标识ID，按照预设规则，确定与该接收端的该当前状态相关的控制信道所在的信道时频位置；
S120，该发送端通过该信道时频位置上的该控制信道，向该接收端发送数据时频位置指示信息、数据占用的时频资源的大小和数据调制编码方式，该数据时频位置指示信息用于指示向该接收端发送的数据所在的数据时频位置。
在本发明实施例中，无线通信***不为非公共的下行控制信道，包括下行资源分配、寻呼信道、随机接入应答、上行资源请求应答(UL_GRANT)、混合自动重传请求应答(HARQ_ACK)、上行功率控制等针对某个或某些终端的控制信道预留专门的时频资源，发送端会根据接收端当前所处的状态，例如，小区搜索后已发起随机接入、等待随机接入应答、已经完成随机接入之后接入***处于无线资源控制_空闲(RRC_IDLE)状态、已经发起业务处于无线资源控制_连接(RRC_CONNECTED)状态等；发送端还根据当前状态下相应的***分配的身份标识ID，如随机接入-无线网络临时标识(Random access-Radio Network Temporary Identity，简称“RA-RNTI”)，临时小区-无线网络临时标识(Temporary cell-Radio Network Temporary Identity，简称“TC-RNTI”)，小区-无线网络临时标识(Cell-Radio Network Temporary Identity，简称“C-RNTI”)等，确定与接收端当前状态相关的控 制信道的信道时频位置，即根据该时频位置可以搜索到与当前状态相关的控制信道，发送端通过该控制信息，指示向接收端传输数据所在的数据时频位置，发送端还可以通过该控制信道发送其它信息，例如数据占用的时频资源的大小，数据调制编码方式(MCS)，混合自动重传请求(Hybrid Automatic Repeat Request，简称“HARQ”)的相关信息，如冗余版本信息等。
因此，本发明实施例的无线资源分配的方法，发送端根据接收端当前状态下的ID，确定与接收端当前状态相关的控制信道的时频位置，再通过该控制信道指示向接收端传输的数据所在时频位置，使得发送端与接收端使用的控制信道可以按需灵活分配，提高了无线通信***的效率、性能和适用性。
在S110中，发送端根据接收端在当前状态下的身份标识ID，确定与该接收端当前状态相关的控制信道的信道时频位置。具体地，接收端处于不同状态下，相应的***会分配不同的ID。例如，若该接收端为终端设备，即用户设备，处于随机接入过程中时，该终端被分配的ID可以为RA-RNTI或TC-RNTI；又例如，若终端已经接入***处于RRC_IDLE状态时，该终端被分配的ID可以为C-RNTI。可选地，该接收端可能处于小区搜索后已发起随机接入、等待随机接入应答、已经接入***处于RRC_IDLE状态、已经发起业务处于RRC_CONNECTED状态等；接收端使用***分配的ID可以包括RA-RNTI，TC-RNTI，C-RNTI等，本发明并不限于此。
可选地，发送端还可以根据接收端的ID，并结合其他信息，确定该信道时频位置，例如，结合小区级别信息，小区级别信息可以为演进的全球小区标识符(Evolved Cell Global Identifier，简称“ECGI”)、小区身份(eNB ID&Cell ID，简称“ECI”)、***消息-无线网络临时标识(System Information-Radio Network Temporary Identity，简称“SI-RNTI”)、寻呼-无线网络临时标识(Paging-Radio Network Temporary Identity，简称“P-RNTI”)等。
在本发明实施例中，根据接收端当前状态下的ID，或者还可以结合其它信息，如小区级别信息，发送端可以确定接收端控制信道的信道时频位置，该信道时频位置可以为相对于某一时频参考点的位置，例如，可以如图2所示，该信道时频位置可以包括相对于该时频参考点的时间偏移量和频率偏移量，例如该信道时频位置可以为图2中的A位置和B位置。具体地，发送端确定接收端当前状态下的ID后，可以根据预设规则，确定相对于某一时频参考点的信道时频位置，可选地，该预设规则可以为哈希函数，如MD5 哈希函数，也可以为模函数，或者还可以为其它函数，对接收端的ID进行处理，或者对接收端的ID与其它小区相关的序列进行合并运算，从而获得相对于某一时频参考点的信道时频位置。
可选地，作为一个实施例，例如，某终端的UE ID为0x36ED(16bit数字)，结合小区级别信息，如小区的ECI为28bit数字0x 13432A01，预设规则可以为根据MD5哈希函数确定时频位置，具体地，把UE ID和小区ECI进行与或(XoR)操作得到数字“0x13431CEC”，此16进制数字的MD5哈希函数checksum为“692b3803ead63124a96d618bc62b7513”，一种方法是截取其中任意给定位置两个两位16进制数并进行模10和模50运算，例如可以根据预先设定的预设规则取最前两位“0x69”即10进制的105取模10运算得到时间偏移量t＝5，取最后两位“0x13”即十进制19取模50运算得到频率偏移量f＝19，得出此终端的控制信道对应的时频偏移量为(t,f)＝(5,19)，即信道时频位置。可选地，发送端还可以按照其它预设规则，例如其它哈希函数，或者模函数等，根据接收端的ID确定信道时频位置，本发明并不限于此。
在本发明实施例中，发送端按照预设规则，根据接收端的ID，或结合其它信息，确定信道时频位置，该时频位置应在接收端所在小区所分配的资源内部(对于终端对终端的直接通信场景中，时频位置应该在通信双方所商定的资源内部)。例如，如果某***无线帧时长为10ms并分为了10个长度为1ms的子帧；载波宽度为10MHz，除去两端的保护频带划分为50个大小为180KHz的无线资源块(resource block，RB)，则时频偏移量中的时间分量t取值应为0-9，频率分量f应为0-49，则该信道时频位置的取值范围为(0,0)≤(t,f)≤(9,49)。
在本发明实施例中，发送端按照预设规则，根据接收端的ID或结合其它信息，确定控制信道所在的信道时频位置，该预设规则可以预先设置在发送端，并且可以通过多种方式向接收端发送该预设规则，以便于接收端也可以根据该预设规则，确定相应的时频位置，从而确定接收端的控制信道。具体地，例如，发送端基站可以使用公共信道，如基站的广播信道等；或者在终端对终端直接通信(D2D)场景中，发送端终端也可以使用公共信道，如发送端终端的发现信道(discovery channel)等，发送端通知所有接收端，即终端，则各个终端接收到相同的预设规则。可选地，基站可以通过只对某一 个或多个终端有效的专用消息，例如随机接入响应消息、RRC连接建立响应消息等，通知该一个或多个终端，则不同终端可以使用不同的预设规则确定时频位置；或者在终端对终端直接通信(D2D)场景中，发送端的终端传递给一个或多个选定接收终端的信令，也可以使得不同接收端使用不同预设规则，本发明实施例并不限于此。
可选地，发送端还可以改变接收端的ID、或者改变通过ID计算时频位置的预设规则，并以信令等方式通知接收端；或者接收端也可以改变自身的ID，并通过随机接入、上行调度请求(scheduling request)或者其他消息通知发送端，相应的时频位置计算会在下一个有效位置做出修改。
在本发明实施例中，发送端根据接收端当前状态下的ID，或者还可以结合其它信息，确定控制信道所在的信道时频位置，可选地，如图2所示，发送端可以根据包括相对于某一时频参考点的时间偏移量和频率偏移量的时频位置，直接确定出控制信道所在的信道时频位置，如图2所示的A位置和B位置；可选地，也可以根据时间偏移量和频率偏移量直接确定出索引信道的位置，即如图2所示的A位置和B位置为索引信道，则再根据索引信道的索引信息，确定出索引信息指示的位置为控制信道所在的信道时频位置，本发明实施例并不限于此。
在本发明实施例中，通过ID或结合其它信息确定信道时频位置，可选地，可以直接确定控制信道位置，或者也可以先确定索引信道位置，该索引信道或者控制信道可以独占该位置处的时频资源，例如，如果该位置的时频资源未分配可以直接使用；如果已经分配给数据信道则可以通过在数据信道打孔(puncturing)的方式使用，也可以和其他信道(如下行数据信道)共享时频资源，例如通过码分、空分(beamforming或者使用某一个空间数据流、codeword或者data layer)，或者直接叠加(superposition)后进行干扰消除的方式共享时频资源，本发明并不限于此。
在S120中，该发送端通过该信道时频位置上的该控制信道，向接收端发送数据时频位置指示信息、数据占用的时频资源的大小和数据调制编码方式，该数据时频位置指示信息用于指示向该接收端发送的数据所在的数据时频位置。可选地，该发送端还可以通过该控制信道，向接收端发送混合自动重传请求HARQ的相关信息，例如冗余版本(RV)信息等，本发明实施例并不限于此。
可选地，在发送端确定接收端的控制信道或者索引信道所在时频位置时，若发送端确定了至少两个接收端具有相同的信道时频位置，则可以通过码分复用方式，或者空间复用的方式，如波束赋型(beamforming)，或者使用不同的空间数据流(data stream)或数据层(data layer)、如使用基于码本的预编码的不同码字(codeword)来区分不同空间位置的终端，或者发送端把属于不同接收端的信号直接叠加之后在接收端进行干扰消除的方式，使得该至少两个接收端的控制信道或者索引信道共用该相同的信道时频位置发送信息，本发明实施例并不限于此。
在本发明实施例中，发送端按照预设规则，根据接收端的ID，确定信道时频位置，并根据信道时频位置上的控制信道确定传输数据所在的数据时频位置，这两种时频位置可以为绝对时频位置，该绝对时频位置可称为物理资源单位(Physical Resource Unit，简称“PRU”)；也可以为扣除不参与分配的时频资源(例如用于公共信道的资源，或者由于避免和相邻小区干扰等原因而不使用的资源)之后的逻辑资源，该逻辑资源可称为虚拟资源单位(Virtual Resource Unit，简称“VRU”)。一个或多个小区内(在终端直接通信场景中，为发送方的时频资源池)的PRU和VRU之间存在特定的映射关系，这种映射关系可以对于小区内所有终端一致，也可以不一致或者部分一致。对于小区内所有终端一致的部分，发送方基站(在终端对终端直接通信场景中，即发送方终端)可以使用公共信道通知所有接收端，即终端；可选地，对于对不同终端不一致的情况，基站(在终端对终端直接通信场景中，即发送方终端)可以通过只对某一个或多个终端有效的专用消息(例如随机接入响应、RRC连接建立响应等)通知该一个或多个终端，本发明实施例并不限于此。
在本发明实施例中，指示控制信道位置的信道时频位置以及指示数据位置的数据时频位置均可以包括PRU和VRU两种情形，发送方基站，(或者终端直接通信场景中的发送方终端)，通过公共消息或者专用消息通知接收方具体可以使用哪种模式。当该两种时频位置使用VRU时，发送端可以根据PRU与VRU的映射关系，确定与PRU对应的VRU，将VRU发送至接收方，而接收方可以根据PRU和VRU的映射关系推算出确切的物理时频位置并进行接收。
具体地，PRU和VRU的映射关系可以如图3所示。发送方基站(或者 终端直接通信场景中的发送方终端)可以使用多种方法指示这种映射关系，例如按照一定方式发送不参与(或参与)映射的PRU编号，具体方式如下：
I、先时间后频率：PRU(0,0)，(0,3)，(0,4)…；
ii、先频率后时间：PRU(0,0)，(4,0)，(6,0)…；
iii、分别传送规则和不规则的PRU，可以对规则的PRU进行编码(例如只传输首个PRU位置、频率间隔、时间间隔、规则PRU的数量等，而不需要传输每一个PRU所在的位置)以节省传输开销，其中，如图3所示，这里的规则的PRU是指按照固定时间间隔发送的PRU，而相反的，不规则的PRU指示发送时间间隔不固定的PRU；另外，可选地这里传输的规则或者不规则的PRU可以是传输可用的PRU，也可以是传输不可用的PRU，具体选择哪一种，可以通过判断可用的PRU和不可用的PRU的传输量，可用的PRU和不可用的PRU哪一种的传输量较小，就传输哪一种；
iv、以位图(bitmap)或者压缩位图等方式对PRU进行二维编码，这里的PRU可以为可用的PRU，也可以为不可用的PRU，具体选择方式也可以通过判断传输量来选择，本发明实施例并不限于此。
因此，本发明实施例的无线资源分配的方法，发送端根据接收端当前状态下的ID，确定与接收端当前状态相关的控制信道的时频位置，再通过该控制信道指示向接收端传输的数据所在时频位置，使得发送端与接收端使用的控制信道可以按需灵活分配，提高了无线通信***的效率、性能和适用性。
上文中结合图1至3，从发送端的角度详细描述了根据本发明实施例的无线资源分配的方法，下面将结合图4，从接收端的角度描述根据本发明实施例的无线资源分配的方法。
图4示出了根据本发明实施例的无线资源分配的方法200的示意性流程图，该方法200可以由接收端执行，该接收端可以为用户设备，例如UE等。如图4所示，该方法200包括：
S210，接收端根据当前状态下的身份标识ID，按照预设规则，确定与该当前状态相关的控制信道所在的信道时频位置；
S220，该接收端通过该信道时频位置上的该控制信道，接收该发送端发送的数据时频位置指示信息、数据占用的时频资源的大小和数据调制编码方式，该数据时频位置指示信息用于指示该接收端的数据所在的数据时频位置。
因此，本发明实施例的无线资源分配的方法，接收端根据当前状态下的ID，确定与该接收端当前状态相关的控制信道的时频位置，再通过该控制信道确定发送端向接收端传输的数据所在时频位置，使得发送端与接收端使用的控制信道可以按需灵活分配，提高了无线通信***的效率、性能和适用性。
在S210中，接收端根据当前状态下的身份标识ID，按照预设规则，确定与该当前状态相关的控制信道所在的信道时频位置。具体地，接收端处于不同状态下，相应的***会分配不同的ID。例如，若该接收端为终端设备，即用户设备，处于随机接入过程中时，该终端被分配的ID可以为RA-RNTI或TC-RNTI；又例如，若终端已经接入***处于RRC_IDLE状态时，该终端被分配的ID可以为C-RNTI。可选地，该接收端可能处于小区搜索后已发起随机接入、等待随机接入应答装、已经接入***处于RRC_IDLE状态、已经发起业务处于RRC_CONNECTED状态等；接收端使用***分配的ID可以包括RA-RNTI，TC-RNTI，C-RNTI等，本发明并不限于此。
可选地，接收端还可以根据自身的ID，并结合其他信息，确定信道时频位置，例如，结合小区级别信息，具体地，该小区级别信息可以为演进的全球小区标识符ECGI、小区身份ECI、SI-RNTI、P-RNTI等。
在本发明实施例中，接收端可以根据当前状态下的ID，或结合其它信息，确定该接收端控制信道的信道时频位置，该信道时频位置可以为相对于某一时频参考点的位置，例如，可以如图2所示，该信道时频位置可以包括相对于该时频参考点的时间偏移量和频率偏移量，例如该信道时频位置可以为图2中的A位置和B位置。具体地，接收端确定自身当前状态下的ID后，可以根据预设规则，确定相对于某一时频参考点的信道时频位置，可选地，该预设规则可以为哈希函数，如MD5哈希函数，也可以为模函数，或者还可以为其它函数，对接收端的ID进行处理，或者对接收端的ID与其它小区相关的序列进行合并运算，从而获得相对于某一时频参考点的信道时频位置。
可选地，作为一个实施例，根据接收端的ID确定信道时频位置，例如，该终端的UE ID为0x36ED(16bit数字)，预设规则可以为根据MD5哈希函数确定时频位置，具体地，字符串“36ED”的一个MD5哈希函数checksum为“a7be1684049bb84bda24ae53b90c0348”，一种方法是截取其中任意给定位置两个两位16进制数并进行模10和模50运算，例如可以根据预设规则取 最前两位“0xa7”即10进制的167取模10运算得到时间偏移量t＝7，取最后两位“0x48”即十进制72取模50运算得到频率偏移量f＝22，得出此终端的控制信道对应的时频偏移量为(t,f)＝(7,22)，即信道时频位置。可选地，接收端还可以按照其它预设规则，例如其它哈希函数，或者模函数等，根据ID确定信道时频位置，而该预设规则可以预先设置于接收端中，也可以通过发送端将该预设规则发送至该接收端，本发明并不限于此。
具体地，接收端按照预设规则，根据ID，或者还可以结合其它信息，确定控制信道所在的信道时频位置，该预设规则可以预先设置在接收端，或者也可以通过多种方式由发送端向接收端发送该预设规则。具体地，例如，发送端基站可以使用公共信道，如基站的广播信道等；或者在终端对终端直接通信(D2D)场景中，发送端终端也可以使用公共信道，如发送端终端的发现信道(discovery channel)等，发送端通知所有接收端，即终端，则各个终端接收到相同的预设规则。可选地，基站可以通过只对某一个或多个终端有效的专用消息，例如随机接入响应消息、RRC连接建立响应消息等，通知该一个或多个终端，则不同终端可以使用不同的预设规则确定时频位置；或者在终端对终端直接通信(D2D)场景中，发送端的终端传递给一个或多个选定接收终端的信令，也可以使得不同接收端使用不同预设规则，本发明实施例并不限于此。
可选地，发送端还可以改变接收端的ID、或者改变通过ID计算时频位置的预设规则，并以信令等方式通知接收端；或者接收端也可以改变自身的ID，并通过随机接入、上行调度请求(scheduling request)或者其他消息通知发送端，相应的时频位置计算会在下一个有效位置做出修改。
在本发明实施例中，接收端按照预设规则，根据ID，或者还可以结合其它信息确定的信道时频位置，应该在该接收端所在小区所分配的资源内部(对于终端对终端的直接通信场景中，时频位置应该在通信双方所商定的资源内部)。例如，如果某***无线帧时长为10ms并分为了10个长度为1ms的子帧；载波宽度为10MHz，除去两端的保护频带划分为50个大小为180KHz的无线资源块(resource block，RB)，则时频偏移量中的时间分量t取值应为0-9，频率分量f应为0-49，则该信道时频位置的取值范围为(0,0)≤(t,f)≤(9,49)。
在本发明实施例中，接收端根据当前状态下的ID，确定控制信道所在 的信道时频位置，可选地，如图2所示，接收端可以根据包括相对于某一时频参考点的时间偏移量和频率偏移量的时频位置，直接确定出控制信道所在的信道时频位置，如图2所示的A位置和B位置；可选地，也可以根据时间偏移量和频率偏移量直接确定出索引信道的位置，即如图2所示的A位置和B位置为索引信道，则再根据索引信道的索引信息，确定出索引信息指示的位置为控制信道所在的信道时频位置，本发明实施例并不限于此。
在本发明实施例中，接收端根据当前状态下的ID，或者还可以结合其它信息，确定信道时频位置，可选地，可能会出现多个接收端确定出同一位置，即多个接收确定的时间偏移量和频率偏移量相同，确定出的控制信道所在的位置为同一位置，则这些确定出相同结果的接收端可以都去检索此时频位置处的控制信道，或者由索引信道指示的控制信道，进而判断该控制信道属于哪一个接收端。具体地，该控制信道内可以包括有终端的ID信息，接收端可以根据该ID信息，以确定该控制信道具体对应哪个接收端。对于这些确定出相同时频位置的接收端中的任意一个接收端来说，如果在该时频位置处没有该接收端对应的信息，则该接收端可以进入休眠状态，直到下一个时频位置(例如下一个无线帧的对应位置)，则该接收端可以进行再次检索，直到该接收端在控制信道中检索到与自身对应的ID信息后，可以确定该控制信道为该接收端对应的控制信道。
可选地，当接收端根据ID信息或者结合其它信息确定了信道时频位置，而该时频位置上的控制信道中还包括了其它接收端的ID信息，即多个接收端确定了相同时频位置时，这些接收端还可以共享该时频资源，并可以通过码分复用方式，或者空间复用的方式，如波束赋型(beamforming)，或者使用不同的空间数据流(data stream)或数据层(data layer)、如使用基于码本的预编码的不同码字(codeword)来区分不同空间位置的终端，或者对于发送端把属于不同接收端的信号直接叠加的情况，接收端可以进行干扰消除，通过上述这些方式，接收端可以确定与接收端自身相对应的控制信道，并获取该控制信道中的信息。
在S220中，该接收端通过确定的该信道时频位置上的与自身对应的控制信道，接收发送端发送的数据时频位置指示信息、数据占用的时频资源的大小和数据调制编码方式，该数据时频位置指示信息用于指示该接收端的数据所在的数据时频位置。可选地，接收端还可以通过该控制信道，接收传输 数据块的HARQ的相关信息，例如冗余版本(RV)信息等，本发明实施例并不限于此。
在本发明实施例中，接收端按照预设规则，根据ID，或者结合其它信息确定信道时频位置，并根据信道时频位置上的控制信道确定传输数据所在的数据时频位置，这两种时频位置可以为绝对时频位置，该绝对时频位置可称为物理资源单元PRU；也可以为扣除不参与分配的时频资源(例如用于公共信道的资源，或者由于避免和相邻小区干扰等原因而不使用的资源)之后的逻辑资源，该逻辑资源可称为虚拟资源单位VRU。一个或多个小区内(在终端直接通信场景中，为发送方的时频资源池)的PRU和VRU之间存在特定的映射关系，这种映射关系可以对于小区内所有终端一致，也可以不一致或者部分一致。对于小区内所有终端一致的部分，发送端基站(在终端对终端直接通信场景中，即发送方终端)可以使用公共信道通知所有接收端，即终端；可选地，对于对不同终端不一致的情况，基站(在终端对终端直接通信场景中，即发送方终端)可以通过只对某一个或多个终端有效的专用消息，例如随机接入响应、RRC连接建立响应等，通知该一个或多个终端，本发明实施例并不限于此。
在本发明实施例中，指示控制信道位置的信道时频位置以及指示数据位置的数据时频位置均可以包括PRU和VRU两种情形，发送方基站，(或者终端直接通信场景中的发送方终端)，通过公共消息或者专用消息通知接收方具体可以使用哪种模式。当该两种时频位置使用VRU时，接收端可以根据PRU和VRU的映射关系推算出确切的物理时频位置并进行接收。
具体地，PRU和VRU的映射关系可以如图3所示。发送端基站(或者终端直接通信场景中的发送方终端)可以使用多种方法指示这种映射关系，例如按照一定方式发送不参与(或参与)映射的PRU编号，而对于接收端，可以根据接收到的不参与(或参与)映射的PRU编号确定具体时频位置，具体地，发送端按照一定方式发送不参与(或参与)映射的PRU编号可以参照上述发送端实施例，在此不再赘述。
应理解，在本发明的各种实施例中，上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本发明实施例的实施过程构成任何限定。
因此，本发明实施例的无线资源分配的方法，接收端根据当前状态下的 ID，确定与该接收端当前状态相关的控制信道的时频位置，再通过该控制信道确定发送端向接收端传输的数据所在时频位置，使得发送端与接收端使用的控制信道可以按需灵活分配，提高了无线通信***的效率、性能和适用性。

因此，本发明实施例的无线资源分配的发送端，发送端根据接收端当前状态下的ID，确定与接收端当前状态相关的控制信道的时频位置，再通过该控制信道指示向接收端传输的数据所在时频位置，使得发送端与接收端使用的控制信道可以按需灵活分配，提高了无线通信***的效率、性能和适用性。
