Description

控制信道资源的获取方法、设备及计算机存储介质Method, device and computer storage medium for acquiring control channel resources

技术领域Technical field

本发明涉及设备到设备(Device-to-Device，D2D)移动通信技术，尤其涉及一种控制信道资源的获取方法、设备及计算机存储介质。The present invention relates to a device-to-device (D2D) mobile communication technology, and in particular, to a method, a device, and a computer storage medium for acquiring control channel resources.

背景技术Background technique

在D2D通信***中，用户设备(User Equipment，UE)之间需要传输D2D数据时，直接由发送该D2D数据的发送端UE通过空中接口传输给接收端UE，如图1所示，其中，D2D UE之间的无线链路称为边链路(Sidelink)。对于应用D2D通信方式的近距离通信UE来说，D2D传输不但节省了无线频谱资源，而且降低了核心网的数据传输压力，能够减少***资源占用，增加蜂窝通信***频谱效率，降低终端发射功耗，并在很大程度上节省网络运营成本。In the D2D communication system, when the user equipment (User Equipment, UE) needs to transmit D2D data, the transmitting end UE that sends the D2D data is directly transmitted to the receiving end UE through the air interface, as shown in FIG. 1 , where D2D The wireless link between UEs is called a side link. For short-range communication UEs using D2D communication mode, D2D transmission not only saves wireless spectrum resources, but also reduces the data transmission pressure of the core network, can reduce system resource occupation, increase the spectrum efficiency of the cellular communication system, and reduce the terminal transmission power consumption. And to a large extent save network operating costs.

D2D UE之间直接进行数据传输时，发送端UE可以按照网络侧的调度配置获得D2D通信的物理边链路控制信道(Physical Sidelink Control Channel，PSCCH)资源和物理边链路共享信道(Physical Sidelink Shared Channel，PSSCH)资源，也可以在给定的PSCCH资源池和PSSCH资源池中竞争，选择资源进行D2D通信控制及数据信息的发射。When the data transmission is directly performed between the D2D UEs, the transmitting end UE may obtain the physical side link control channel (PSCCH) resource and the physical side link shared channel (Physical Sidelink Shared) of the D2D communication according to the scheduling configuration of the network side. Channel, PSSCH) resources can also compete in a given PSCCH resource pool and PSSCH resource pool, and select resources for D2D communication control and data information transmission.

然而，D2D UE基于PSCCH和PSSCH资源传输数据时，仅能够进行单向的广播/组播通信，发送端UE对D2D数据进行盲发射，无法获知接收端UE对于D2D数据的接收情况，使得边链路信道资源的利用率低下。However, when the D2D UE transmits data based on the PSCCH and the PSSCH resources, only one-way broadcast/multicast communication can be performed, and the transmitting end UE blindly transmits the D2D data, and the receiving end UE cannot receive the D2D data reception status, so that the edge chain is obtained. The utilization of channel resources is low.

下面对本发明实施例提供的控制信道资源的获取方法进行详细说明。The method for acquiring control channel resources provided by the embodiments of the present invention is described in detail below.

图2为本发明实施例一提供的控制信道资源的获取方法的流程图。本实施例提供的控制信道资源的获取方法具体可以由接收端UE执行，具体的，本实施例提供的方法可以包括：FIG. 2 is a flowchart of a method for acquiring control channel resources according to Embodiment 1 of the present invention. The method for obtaining the control channel resource provided in this embodiment may be specifically performed by the UE at the receiving end. Specifically, the method provided in this embodiment may include:

步骤101、第一UE获取PSSCCH资源；Step 101: The first UE acquires a PSSCCH resource.

步骤102、所述第一UE在获取的所述PSSCCH资源上发送边链路反馈控制信息。Step 102: The first UE sends edge link feedback control information on the acquired PSSCCH resource.

在步骤101中，所述第一UE获取PSSCCH资源，具体可以包括：In step 101, the acquiring, by the first UE, the PSSCCH resource may include:

所述第一UE接收第二UE或网络侧设备发送的高层信令，所述高层信令中包含PSSCCH资源指示信息；所述第一UE根据所述PSSCCH资源指示信息获取所述PSSCCH资源；或者，所述第一UE接收所述第二UE发送的SCI，所述SCI中包含的PSSCCH资源指示信息；所述第一UE根据所述PSSCCH资源指示信息获取所述PSSCCH资源；或者，所述第一UE接收所述第二UE在PSCCH资源上发送的SCI，并根据预定义的PSCCH资源与PSSCCH资源索引关系，获取与所述PSCCH资源对应的所述PSSCCH资源；或者，所述第一UE接收所述第二UE在PSSCH资源上发送的数据信息，并根据预定义的PSSCH资源与PSSCCH资源索引关系，获取与所述PSSCH资源对应的所述PSSCCH资源。The first UE receives the high layer signaling sent by the second UE or the network side device, where the high layer signaling includes the PSSCCH resource indication information; the first UE acquires the PSSCCH resource according to the PSSCCH resource indication information; or The first UE receives the SCI sent by the second UE, the PSSCCH resource indication information included in the SCI, and the first UE according to the The PSSCCH resource indication information is used to acquire the PSSCCH resource; or the first UE receives the SCI sent by the second UE on the PSCCH resource, and acquires the PSCCH according to the predefined PSCCH resource and the PSSCCH resource index relationship. The PSSCCH resource corresponding to the resource; or the first UE receives the data information sent by the second UE on the PSSCH resource, and acquires the PSSCH resource according to the predefined PSSCH resource and the PSSCCH resource index relationship. The PSSCCH resource.

需要说明的是，第二UE或网络侧设备向第一UE发送的高层信令可以是RRC消息，或者由网络侧设备发送的***信息块(SIB)消息。It should be noted that the high layer signaling sent by the second UE or the network side device to the first UE may be an RRC message or a System Information Block (SIB) message sent by the network side device.

本实施例中，所述网络侧设备具体可以包括以下任意一种设备：eNB、RN、MCE、GW、MME、EUTRAN OAM管理器。In this embodiment, the network side device may specifically include any one of the following: an eNB, an RN, an MCE, a GW, an MME, and an EUTRAN OAM manager.

通过RRC消息指示PSSCCH资源时，PSSCCH资源指示信息具体可以包含在ProseCommConfig信息单元中；通过SIB指示PSSCCH资源时，对所述PSSCCH资源的指示包含在专用SIB中。上述第一UE获取PSSCCH资源的方法，在不冲突的情况下可以任意组合，本实施例对此不做具体限定。When the PSSCCH resource is indicated by the RRC message, the PSSCCH resource indication information may be specifically included in the ProseCommConfig information element; when the PSSCCH resource is indicated by the SIB, the indication of the PSSCCH resource is included in the dedicated SIB. The method for acquiring the PSSCCH resource by the first UE may be arbitrarily combined in the case of no conflict, which is not specifically limited in this embodiment.

在实际应用中，所述PSSCCH资源指示信息指示所述PSSCCH资源所在的子帧和/或RB；或者，所述PSSCCH资源指示信息指示所述PSSCCH资源的信道索引号。In an actual application, the PSSCCH resource indication information indicates a subframe and/or an RB where the PSSCCH resource is located; or the PSSCCH resource indication information indicates a channel index number of the PSSCCH resource.

对于PSSCCH资源指示信息指示PSSCCH资源所在的子帧的情况，可选的，该PSSCCH资源指示信息可以直接指示所述PSSCCH资源所在子帧的子帧号，例如指示PSSCCH资源所在的子帧的子帧号为#2，或#8，当存在PSSCCH资源池时，PSSCCH资源指示信息所指示的子帧应是PSSCCH资源池中的子帧。For the case where the PSSCCH resource indication information indicates the subframe in which the PSSCCH resource is located, the PSSCCH resource indication information may directly indicate the subframe number of the subframe in which the PSSCCH resource is located, for example, the subframe indicating the subframe in which the PSSCCH resource is located. The number is #2, or #8. When there is a PSSCCH resource pool, the subframe indicated by the PSSCCH resource indication information shall be a subframe in the PSSCCH resource pool.

对于PSSCCH资源指示信息指示PSSCCH资源所在的子帧的情况，可选的，该PSSCCH资源指示信息可以指示所述PSSCCH资源所在的子帧与相应的PSCCH资源或PSSCH资源所在的子帧之间的时序关系。For the case that the PSSCCH resource indication information indicates the subframe in which the PSSCCH resource is located, optionally, the PSSCCH resource indication information may indicate the subframe in which the PSSCCH resource is located. The timing relationship between the corresponding PSCCH resource or the subframe in which the PSSCH resource is located.

本实施例中，PSSCCH资源用于承载边链路反馈控制信息，该边链路反馈控制信息与边链路数据传输或控制指示信息直接相关，例如，第一UE在PSCCH资源上接收的SCI中指示要求上报信道测量反馈，则第一UE在相应的PSSCCH资源上发送CSI反馈报告；第一UE在PSCCH资源上接收的SCI中，指示了边链路数据传输的PSSCH资源，第一UE根据SCI中指示，在相应的PSSCH资源上接收D2D通信数据包，则第一UE在相应的PSSCCH资源上发送A/N反馈，用于向数据发送端第二UE反馈对此数据包的接收结果。In this embodiment, the PSSCCH resource is used to carry the side link feedback control information, and the edge link feedback control information is directly related to the side link data transmission or control indication information, for example, the first UE is in the SCI received on the PSCCH resource. Instructing to report channel measurement feedback, the first UE sends a CSI feedback report on the corresponding PSSCCH resource; the first UE indicates the PSSCH resource of the side link data transmission in the SCI received on the PSCCH resource, and the first UE is based on the SCI. The receiving, by the first UE, the D2D communication data packet on the corresponding PSSCH resource, the first UE sends the A/N feedback on the corresponding PSSCCH resource, and is used to feed back the receiving result of the data packet to the second UE of the data sending end.

由此可以看出，PSSCCH资源与PSCCH资源或PSSCH资源有一定的对应关系，在高层信令或SCI中可以通过指示与相应的PSCCH资源或PSSCH资源所在子帧之间的时序关系，指示相应的PSSCCH资源所在的子帧。It can be seen that the PSSCCH resource has a certain correspondence with the PSCCH resource or the PSSCH resource, and the high-level signaling or the SCI can indicate the corresponding timing relationship by indicating the timing relationship with the corresponding PSCCH resource or the subframe where the PSSCH resource is located. The subframe in which the PSSCCH resource is located.

例如，PSCCH资源或PSSCH资源在子帧#n上发送，而相应的PSSCCH资源在子帧#m上发送，子帧#n与子帧#m之间的子帧间隔为k，则在RRC消息或SCI中通过指示k值体现二者间的时序关系，即可以指示出相应的PSSCCH资源所在的子帧；当存在PSSCCH资源池时，所指示的PSSCCH子帧应是包含在PSSCCH资源池中的子帧，则上述时序关系可以描述为，所指示的PSSCCH子帧为子帧#n+k，及子帧#n+k之后，且包含在PSSCCH资源池中的第一个子帧。For example, the PSCCH resource or the PSSCH resource is transmitted on the subframe #n, and the corresponding PSSCCH resource is transmitted on the subframe #m, and the subframe interval between the subframe #n and the subframe #m is k, then the RRC message is used. Or the SCI indicates that the timing relationship between the two is indicated by the value of the k, that is, the subframe in which the corresponding PSSCCH resource is located may be indicated; when the PSSCCH resource pool is present, the indicated PSSCCH subframe shall be included in the PSSCCH resource pool. For the subframe, the timing relationship may be described as that the indicated PSSCCH subframe is subframe #n+k, and after subframe #n+k, and is included in the first subframe in the PSSCCH resource pool.

当T表示周期内PSSCCH资源池中的子帧数量时，一个周期内PSSCCH资源池中包含的所有子帧顺次编号为子帧#0，#1，…，#T-1，则PSSCCH子帧#m_i即对应于资源池中的子帧#i。其中，用于D2D通信的资源池可按周期配置，每个周期内的资源池配置相同或按一定规则循环映射，对于PSCCH和/或PSSCH和/或PSSCCH资源池，一般配置为相同的周期，即对上述三种信道资源池配置统一的周期，以及相同的周期起始子帧位置，在不另行说明的情况下，对D2D通信中的周期即指统一周期配置，则可称为PSCCH资源池周期、或PSSCH资源池周期、也可称为PSSCCH资源池周期。另外，不排除在特殊场景下对三种信道资源池配置不同的周期或起始位置。When T indicates the number of subframes in the PSSCCH resource pool in a period, all subframes included in the PSSCCH resource pool in one cycle are sequentially numbered as subframes #0, #1, ..., #T-1, then the PSSCCH subframe #m _i corresponds to subframe #i in the resource pool.

The period, or PSSCH resource pool period, may also be referred to as a PSSCCH resource pool period. In addition, it is not excluded to configure different periods or starting positions for three channel resource pools in a special scenario.

当T表示用于边链路传输的子帧数量时，所有边链路传输可用的子帧顺次编号为子帧#0，#1，…，#T-1，则PSSCCH子帧#m_i即对应于其中的子帧#i。When T represents the number of subframes used for edge link transmission, all subframes available for edge link transmission are sequentially numbered as subframes #0, #1, ..., #T-1, then PSSCCH subframe #m _i That is, corresponding to the subframe #i therein.

当T表示周期内PSCCH资源池中的子帧数量时，一个周期内PSCCH资源池中包含的所有子帧顺次编号为子帧#0，#1，…，#T-1，则PSSCCH子帧#m_i即对应于资源池中的子帧#i。When T represents the number of subframes in the PSCCH resource pool in a period, all subframes included in the PSCCH resource pool in one cycle are sequentially numbered as subframes #0, #1, ..., #T-1, then the PSSCCH subframe #m _i corresponds to subframe #i in the resource pool.

例如，网络侧设备通过RRC消息为第一UE指示所配置的PSSCCH资源的信道索引号为index_PSSCCH i，***中采用将index_PSSCCH i对T进行取模运算，确定PSSCCH资源对应的子帧#m_i，其中，T为PSSCCH资源池中的子帧数量，第一UE接收到网络侧的RRC消息指示后，从中获得index_PSSCCH i＝14，且PSSCCH资源池中包含8个子帧，如图7中所示，即T＝8，则可以确定所配置的PSSCCH资源的子帧#m_i为：i＝index_PSSCCH i mod T＝14 mod 8＝6。For example, the network side device indicates, by using the RRC message, that the channel index number of the configured PSSCCH resource is index _PSSCCH i, and the system uses the index _PSSCCH i to perform modulo operation on the T, and determines the subframe #m corresponding to the PSSCCH resource. _i , where T is the number of subframes in the PSSCCH resource pool. After receiving the RRC message indication on the network side, the first UE obtains index _PSSCCH i=14, and the PSSCCH resource pool includes 8 subframes, as shown in FIG. 7 As shown, that is, T=8, it can be determined that the subframe #m _i of the configured PSSCCH resource is: i=index _PSSCCH i mod T=14 mod 8=6.

其中，F为正整数，且F的取值为以下任意一种：PSSCCH资源池中的RB数量；配置为边链路传输的RB数量；***带宽内的RB数量；***预定义的固定数值；PSCCH资源池中的RB数量；PSSCH资源池中的RB数量。Wherein, F is a positive integer, and the value of F is any one of the following: the number of RBs in the PSSCCH resource pool; the number of RBs configured for edge link transmission; the number of RBs in the system bandwidth; a predefined fixed value of the system; The number of RBs in the PSCCH resource pool; the number of RBs in the PSSCH resource pool.

例如，第二UE在SCI中为第一UE指示所配置的PSSCCH资源的信道索引号为index_PSSCCH i，***中采用将index_PSSCCH i除以F向下取整运算，确定PSSCCH资源的RB，其中，F为PSSCCH资源池中的RB数量，第一UE接收到SCI信息后，从中获得index_PSSCCH i＝27，且PSSCCH资源池中包含10个RB，如图8中所示，即F＝10，则可以确定所配置的PSSCCH资源的相对RB索引号

为：

即，PSSCCH资源所在的RB为PSSCCH资源池中的RB index＝2的RB。For example, the second UE indicates, in the SCI, that the channel index number of the configured PSSCCH resource is index _PSSCCH i, and the system uses the index _PSSCCH i divided by the F rounding operation to determine the RB of the PSSCCH resource, where F is the number of RBs in the PSSCCH resource pool. After receiving the SCI information, the first UE obtains index _PSSCCH i=27, and the PSSCCH resource pool contains 10 RBs, as shown in FIG. 8, that is, F=10. Then, the relative RB index number of the configured PSSCCH resource may be determined.

for:

That is, the RB where the PSSCCH resource is located is an RB with RB index=2 in the PSSCCH resource pool.

上述技术方案中，通过指示PSSCCH资源的信道索引号指示所配置的PSSCCH资源的子帧和/或RB资源，可以降低资源指示开销，同时提供较灵活的资源配置，满足UE的PSSCCH资源需求，达到充分利用***资源，协调干扰，提高资源利用率的效果。In the foregoing technical solution, by indicating the channel index number of the PSSCCH resource, the subframe and/or the RB resource of the configured PSSCCH resource, the resource indication overhead can be reduced, and the flexible resource configuration is provided to meet the PSSCCH resource requirement of the UE. Make the most of system resources, Coordinate interference and improve the efficiency of resource utilization.

在另一种实现方式中，可以预定义PSSCCH资源与相应的PSCCH资源或PSSCH资源之间的索引关系，从而可以根据PSCCH资源或PSSCH资源，获取相应的PSSCCH资源；即，通过预定义的PSCCH/PSSCH资源与相应的PSSCCH资源的索引关系，确定PSSCCH资源的子帧和/或RB资源，从而可以在无需任何信令指示开销的情况下，为第一UE隐式指示出相应的PSSCCH资源，大大降低了资源指示开销，同时提供较灵活的资源配置，满足UE的PSSCCH资源需求，达到充分利用***资源，协调干扰，提高资源利用率的效果。In another implementation manner, the index relationship between the PSSCCH resource and the corresponding PSCCH resource or the PSSCH resource may be predefined, so that the corresponding PSSCCH resource may be obtained according to the PSCCH resource or the PSSCH resource; that is, through the predefined PSCCH/ The index relationship between the PSSCH resource and the corresponding PSSCCH resource determines the subframe and/or the RB resource of the PSSCCH resource, so that the corresponding PSSCCH resource can be implicitly indicated for the first UE without any signaling indication overhead. The resource indication overhead is reduced, and the flexible resource configuration is provided to meet the PSSCCH resource requirements of the UE, so as to fully utilize system resources, coordinate interference, and improve resource utilization.

可选地，所述第一UE可以根据所述PSCCH/PSSCH资源与PSSCCH资源索引关系，确定与所述PSCCH资源所在的子帧对应的所述PSSCCH资源所在的子帧。Optionally, the first UE may determine, according to the PSCCH/PSSCH resource and the PSSCCH resource index relationship, a subframe in which the PSSCCH resource corresponding to the subframe in which the PSCCH resource is located.

具体地，***预定义PSCCH/PSSCH资源所在的子帧#n与PSSCCH资源所在的子帧#m之间一一对应的索引关系，形成固定的索引关系，则第一UE在子帧#n接收到PSCCH/PSSCH资源上的信息后，相应的在子帧#m上的PSSCCH资源上承载发送相应的边链路反馈控制信息。Specifically, the system pre-defines a one-to-one index relationship between the subframe #n where the PSCCH/PSSCH resource is located and the subframe #m where the PSSCCH resource is located, and forms a fixed index relationship, and the first UE receives in the subframe #n. After the information on the PSCCH/PSSCH resource is sent, the corresponding side link feedback control information is sent on the PSSCCH resource on the subframe #m.

可选地，所述第一UE根据所述PSCCH/PSSCH资源与PSSCCH资源索引关系，获取所述PSCCH资源所在的子帧与所述PSSCCH资源所在的子帧之间的时序关系，根据所述时序关系，确定所述PSSCCH资源所在的子帧。Optionally, the first UE acquires a timing relationship between a subframe in which the PSCCH resource is located and a subframe in which the PSSCCH resource is located according to the PSCCH/PSSCH resource and the PSSCCH resource index relationship, according to the timing Relationship: determining a subframe in which the PSSCCH resource is located.

具体地，PSSCCH资源所在的子帧#m与相应的PSCCH/PSSCH资源所在子帧#n之间，由***预定义相对时序关系，即二者之间的子帧间隔k，则子帧#m为子帧#n之后的第k个子帧。进一步的，当存在PSSCCH资源池配置时，所指示的PSSCCH子帧应是包含在PSSCCH资源池中的子帧，则上述时序关系可以描述为，所指示的PSSCCH子帧为子帧#n+k，及子帧 #n+k之后，且包含在PSSCCH资源池中的第一个子帧；其中，n，m为子帧序号，取值[0～9]，则当n+k大于9时，m等于n+k对10取模。Specifically, between the subframe #m where the PSSCCH resource is located and the subframe #n where the corresponding PSCCH/PSSCH resource is located, the relative timing relationship is predefined by the system, that is, the subframe interval k between the two, then the subframe #m It is the kth subframe after subframe #n. Further, when there is a PSSCCH resource pool configuration, the indicated PSSCCH subframe should be a subframe included in the PSSCCH resource pool, and the foregoing timing relationship may be described as: the indicated PSSCCH subframe is a subframe #n+k , and sub-frames After #n+k, and included in the first subframe of the PSSCCH resource pool; where n, m is the subframe number, and the value [0~9], when n+k is greater than 9, m is equal to n +k takes a modulo of 10.

可以理解的是，当相应的PSSCH资源包含多个子帧时，在多个PSSCH子帧中，以第一个或最后一个PSSCH子帧作为子帧#n，进一步确定相应的PSSCCH子帧#m；当相应的PSSCH资源上承载同一个数据包的多次重复传输时，在用于承载同一个数据包的多次传输的相应的多个PSSCH子帧中，以第一个或最后一个PSSCH子帧作为子帧#n，进一步确定相应的PSSCCH子帧#m。It can be understood that when the corresponding PSSCH resource includes multiple subframes, in the multiple PSSCH subframes, the first or last PSSCH subframe is used as the subframe #n, and the corresponding PSSCCH subframe #m is further determined; When the corresponding PSSCH resource carries multiple repeated transmissions of the same data packet, in the corresponding multiple PSSCH subframes for carrying multiple transmissions of the same data packet, the first or last PSSCH subframe is used. As the subframe #n, the corresponding PSSCCH subframe #m is further determined.

例如，TDD***中，预定义一种子帧#n与子帧#m之间的索引关系，如表一所示。For example, in the TDD system, an index relationship between a subframe #n and a subframe #m is predefined, as shown in Table 1.

表一Table I

根据***定义的子帧#n与子帧#m的索引关系，第一UE在子帧#n接收到PSCCH/PSSCH资源上的信息后，按相应的索引关系，即可确定相应的PSSCCH资源所在的子帧#m；例如，***采用TDD configuration #1，第一UE在子帧#2上收到SCI指示，要求反馈对边链路的测量报告，则第一UE在子帧#7上的PSSCCH资源上承载边链路CSI报告，向第二UE进行反馈发送。 According to the index relationship between the subframe #n and the subframe #m defined by the system, after receiving the information on the PSCCH/PSSCH resource in the subframe #n, the first UE can determine the corresponding PSSCCH resource according to the corresponding index relationship. Subframe #m; for example, the system adopts TDD configuration #1, the first UE receives the SCI indication on subframe #2, and requests feedback of the measurement report of the opposite link, then the first UE is on subframe #7. The bearer link CSI report on the PSSCCH resource is sent back to the second UE.
