Applying.
本申请涉及通信技术领域,特别涉及一种构建CoMP集合的方法和设备。The present application relates to the field of communication technologies, and in particular, to a method and device for constructing a CoMP set.
随着第五代移动通信技术(5-Generation,5G)网络部署节点和天线阵列的密度急剧增长,5G网络的超密集化在提高系统通信服务质量的同时给多点协作(Coordinated Multiple Points,CoMP)技术带来一系列的问题。一方面,频谱资源的稀缺性使得在超密集无线网络CoMP技术中干扰变得不可避免;另一方面,5G网络密集化带来复杂的基站/终端之间资源竞争使得CoMP技术需要高效的协作区域分配方案。As the density of the fifth-generation mobile communication technology (5-Generation, 5G) network deployment nodes and antenna arrays has increased sharply, the ultra-dense of 5G networks improves the quality of system communication services while providing coordinated multiple points (CoMP) ) Technology brings a series of problems. On the one hand, the scarcity of spectrum resources makes interference in the ultra-dense wireless network CoMP technology unavoidable; on the other hand, the denseness of 5G networks brings complex resource competition between base stations / terminals, which makes CoMP technology need efficient cooperation areas Distribution plan.
现有的通信系统已经有很多方法来处理CoMP集构建问题,而近年来各公司也不断在5G标准化会议上提出新的CoMP提案。现有的CoMP集构建技术在第一阶段(phase 1,Rel-15)有两个主流提案,即基于X2接口特性分配CoMP协作区域和自适应协作区域分配。基于X2接口特性分配CoMP协作区域的方案对时延敏感,如果基站间信息交互时延较大会给系统性能带来很大影响;自适应协作区域分配的方案对于终端的移动不能快速得出CoMP集的构建方案,因此不能及时应对终端的移动。Existing communication systems already have many methods to deal with the issue of CoMP set construction. In recent years, companies have also continuously proposed new CoMP proposals at 5G standardization meetings. The existing CoMP set construction technology has two mainstream proposals in the first phase (Rel-15), namely, the allocation of CoMP collaboration area and adaptive collaboration area allocation based on X2 interface characteristics. The scheme of allocating CoMP cooperation areas based on the characteristics of the X2 interface is sensitive to delay. If the information exchange between base stations has a large delay, it will greatly affect the system performance. The scheme of adaptive cooperation area allocation cannot quickly obtain the CoMP set for the movement of terminals. The construction solution can not respond to the movement of the terminal in time.
综上所述,目前的CoMP集合构建方法在基站间信息交互时延较大时会给系统性能带来很大影响,并且不能及时应对终端的移动。In summary, the current method of constructing a CoMP set will have a large impact on system performance when the information exchange delay between base stations is large, and it cannot respond to terminal movement in a timely manner.

下面结合说明书附图对本申请实施例做进一步详细描述。The embodiments of the present application are described in further detail below with reference to the accompanying drawings.
如图1所示,本申请实施例构建CoMP集合的系统包括:终端10、基站20。As shown in FIG. 1, the system for constructing a CoMP set in the embodiment of the present application includes a terminal 10 and a base station 20.

本申请实施例中,终端通过测量信号强度生成包括至少两个基站的候选集合并向所述候选集合中的至基站发送CoMP集合加入请求,基站在接收到终端发送的CoMP集合加入请求,判断是否加入CoMP集合,在确定加入CoMP集合后通知所述终端同意加入CoMP集合,终端从返回同意加入CoMP集合的基站中选择基站加入到CoMP集合中。由于本申请实施例中基站与基站之间无需交互,且CoMP集合的构建依靠基站与终端之间请求与回复进行判决,终端与基站间的交互只包含请求与回复信息,信令极短,在降低系统复杂度的同时减少了信令开销。In the embodiment of the present application, the terminal generates a candidate set including at least two base stations by measuring the signal strength and sends a CoMP set join request to the base station in the candidate set. The base station determines whether the CoMP set join request sent by the terminal is received. After joining the CoMP set, after determining to join the CoMP set, the terminal is notified to agree to join the CoMP set, and the terminal selects a base station to join the CoMP set from the base stations returning to agree to join the CoMP set. Since there is no interaction between the base station and the base station in the embodiment of the present application, and the construction of the CoMP set depends on the request and reply between the base station and the terminal for decision, the interaction between the terminal and the base station only includes request and reply information, and the signaling is extremely short. It reduces signaling complexity while reducing system complexity.
本申请实施例中,终端通过测量信号强度生成包含多个基站的候选集合。In the embodiment of the present application, the terminal generates a candidate set including multiple base stations by measuring signal strength.
其中,信号强度可以由接收功率和/或信号噪声确定。The signal strength may be determined by the received power and / or signal noise.
其中,所述候选集合的形式包括但不限于下列方式中的部分或全部:The form of the candidate set includes, but is not limited to, part or all of the following modes:
列表,数组,堆栈,队列。List, array, stack, queue.
以终端测量接收功率为例进行举例说明。如图2A所示,终端通过测量基站发射的信道状态信息参考信号在终端的接收功率,将接收功率大于设定第一阈值的基站加入候选列表。Take the terminal's measurement of received power as an example for illustration. As shown in FIG. 2A, the terminal measures the received power of the channel state information reference signal transmitted by the base station at the terminal, and adds the base station whose received power is greater than the first threshold to the candidate list.
假设,设定的第一阈值为终端u
j最低无限通信服务的接收功率阈值p-TH
j,p
ij是基站BS
i发射的信号在终端u
j的接收功率,可以通过测量信道状态信息参考信号的接收功率得到。
Suppose, a first threshold value set in the terminal u j minimum unlimited communication service reception power threshold value p-TH j, p ij is the received power of a signal the base station BS i transmitted terminal u j, and by measuring the channel state information reference signal The received power is obtained.
具体的,终端u
j接收到各基站发射的信道状态信息参考信号后,测量各基站信号在终端u
j的接收功率,若接收功率p
ij大于终端u
j最低无限通信服务的接收功率阈值p-TH
j,即p
ij>p-TH
j,则代表基站BS
i可以加入终端u
j的候选列表。
Specifically, after receiving the channel state information reference signal transmitted by each base station, the terminal u j measures the received power of each base station signal at the terminal u j . If the received power p ij is greater than the received power threshold p- of the minimum infinite communication service of the terminal u j TH j , that is, p ij > p-TH j , represents that the base station BS i can join the candidate list of the terminal u j .
假设各基站信号在终端u
j的接收功率有:
Assume that the received power of each base station signal at the terminal u j is:
p
1j>p
2j>p
3j>…>p
L(j)j>p-TH
j>p
L(j)+1,j>…
p 1j > p 2j > p 3j >… > p L (j) j > p-TH j > p L (j) + 1, j >…
则前L个基站可以加入到终端u
j的候选列表。
The first L may be added to the list of candidate base stations u j of the terminal.
将可以加入到候选集合的基站加入候选集合时可以排序或不排序。在本申请的某些实施例中,排序时可以按照从小到大或从大到小的顺序。The base stations that can be added to the candidate set can be sorted or not sorted when added to the candidate set. In some embodiments of the present application, the sorting may be performed in ascending or descending order.
其中,终端将前L个基站按接收功率从大到小排列即生成图2A所示候选列表。The terminal arranges the first L base stations according to the received power from large to small to generate the candidate list shown in FIG. 2A.
以终端测量接收功率为例,针对不同的终端,其生成的候选集合一般不同,在每次生成候选集合时都需要将各个基站的接收功率与设定第一阈值进行比较,在本申请的某些实施例中,可以预先对各基站的接收功率进行量化,在生成候选集合时直接根据量化结果判断基站是否加入候选集合。Taking the terminal's measurement of received power as an example, the candidate sets generated by different terminals are generally different for each terminal. Each time a candidate set is generated, the received power of each base station needs to be compared with a set first threshold. In some embodiments, the received power of each base station may be quantized in advance, and when generating the candidate set, it is directly determined whether the base station joins the candidate set according to the quantization result.
在本申请的某些实施例中,可以根据优先级指数对各个基站的接收功率进行量化,假设,第i个基站BS
i在第j个终端u
j的优先级指数函数可以表示为:
In some embodiments of the present application, the received power of each base station can be quantified according to the priority index. It is assumed that the priority index function of the i-th base station BS i at the j-th terminal u j can be expressed as:
PI
j(BS
i)=p
ij
PI j (BS i ) = p ij
其中p
ij是基站BS
i发射的信道状态信息参考信号在终端u
j的接收功率。
Where p ij is the received power of the channel state information reference signal transmitted by the base station BS i at the terminal u j .
本申请实施例中,生成候选集合之后,终端向候选集合中的至少一个基站发送CoMP集合加入请求。CoMP集合中基站的数目越大,则有更多基站为同一个终端服务,带来的性能增益也就更大,但同时消耗更多资源,反之,CoMP集合中基站的数目越小,则为同一个终端服务的基站的数目也就越小,消耗资源减少,但同时性能增益下降。In the embodiment of the present application, after generating the candidate set, the terminal sends a CoMP set joining request to at least one base station in the candidate set. The larger the number of base stations in the CoMP set, the more base stations serve the same terminal, and the performance gain is greater, but at the same time consumes more resources. Conversely, the smaller the number of base stations in the CoMP set, the The smaller the number of base stations served by the same terminal, the lower the consumption of resources, but at the same time the performance gain decreases.
在本申请的某些实施例中,终端可以对CoMP集合中的基站数量设置一个适宜的预设数量,在CoMP集合中的基站数量达到预设数量时,CoMP集合满额,终端完成CoMP集合的构建。当终端所有回复同意请求的基站数量小于终端CoMP集合中基站数量的预设数量时,需要调整CoMP集合中的基站数量的预设数量。In some embodiments of the present application, the terminal may set a suitable preset number for the number of base stations in the CoMP set. When the number of base stations in the CoMP set reaches the preset number, the CoMP set is full and the terminal completes the construction of the CoMP set. . When the number of all base stations responding to the consent request of the terminal is less than the preset number of base stations in the CoMP set of the terminal, the preset number of base stations in the CoMP set needs to be adjusted.
假设终端u
j的CoMP集合的空额数为e-CoMP(j),当终端u
j所有回复同意请求的基站数目小于终端u
j的CoMP集合中基站数量的预设数量,即不足以填满CoMP集合时,认为终端u
j的CoMP集合已不可能被填满,此时令:
U j is assumed that the terminal vacancies CoMP set number of e-CoMP (j), when a preset number of terminals all numbers u j is smaller than the base stations respond to accede to the request of the terminal u j CoMP set number of base stations, i.e. not sufficient to fill CoMP At the time of assembly, it is considered that the CoMP set of the terminal u j can no longer be filled.
e-CoMP(j)=0e-CoMP (j) = 0
当e-CoMP(j)=0时终端u
j判定CoMP集合中的基站数目达到预设数量;否则,认为终端u
j的CoMP集合中的基站数目尚未达到预设数量。
When e-CoMP (j) = 0, the terminal u j determines that the number of base stations in the CoMP set reaches a preset number; otherwise, it is considered that the number of base stations in the CoMP set of the terminal u j has not reached the preset number.
其中,终端向候选集合中的基站发送CoMP集合加入请求的方式有不等反馈发送和等反馈发送。The manner in which the terminal sends the CoMP set join request to the base station in the candidate set includes unequal feedback sending and equal feedback sending.
发送方式一、不等反馈发送。Sending method 1: Sending feedback without waiting.
具体的,终端在CoMP集合中的基站数量未达到预设数量时,向候选集合内尚未发送CoMP集合加入请求的N个基站发送CoMP集合加入请求,终端在向基站发送CoMP集合请求之后不需要等待基站同意加入或拒绝加入的 反馈信息,可以继续向候选集合中尚未发送CoMP集合加入请求的基站发送CoMP集合加入请求。Specifically, when the number of base stations in the CoMP set does not reach the preset number, the terminal sends a CoMP set join request to N base stations in the candidate set that have not yet sent a CoMP set join request. The terminal does not need to wait after sending the CoMP set request to the base station. The feedback information that the base station agrees to join or refuses to join may continue to send the CoMP set join request to the base station in the candidate set that has not yet sent the CoMP set join request.
其中,终端向候选集合中的N个基站发送CoMP集合加入请求时有两种方式:并行发送和串行发送。There are two ways for the terminal to send a CoMP set join request to N base stations in the candidate set: parallel sending and serial sending.
方式1、并行发送,即终端向候选集合中的N个基站同时发送CoMP集合加入请求。 Method 1. Parallel transmission, that is, the terminal sends a CoMP set join request to N base stations in the candidate set at the same time.
以生成候选列表为例,如图2B所示,终端u
j向候选列表中的3个基站:BS
1,BS
2,BS
3同时发送CoMP集合加入请求。
To generate a candidate list as an example, shown in Figure 2B, terminal u j in the candidate list to the base station 3: BS 1, BS 2, BS 3 was added simultaneously transmitting request CoMP set.
终端向候选集合中的N个基站同时发送CoMP集合加入请求时的情况有很多种,下面列举几种。There are many cases when a terminal sends a CoMP set join request to N base stations in the candidate set at the same time, and the following are listed below.
(1)终端向候选集合中的剩余全部基站同时发送CoMP集合加入请求。(1) The terminal sends a CoMP set join request to all remaining base stations in the candidate set at the same time.
假设终端u
j的CoMP集合中基站数量的预设数量为10,已经添加到CoMP集合中的基站数为4,还需要再添加6个基站,而候选集合中的尚未发送CoMP集合加入请求的基站的数量为7。终端u
j向候选集合中剩余的7个基站同时发送CoMP集合加入请求。
Assume that the preset number of base stations in the CoMP set of the terminal u j is 10, the number of base stations that have been added to the CoMP set is 4, and another 6 base stations need to be added, and the base stations in the candidate set that have not yet sent a CoMP set join request The number is 7. The terminal u j sends a CoMP set join request to the remaining 7 base stations in the candidate set at the same time.
若7个基站全部回复同意请求,则终端u
j从这7个基站中选取6个基站加入到CoMP集合。若这7个基站中只有5个基站回复同意请求,这时终端将这5个基站全部加入到CoMP集合并更新CoMP集合的预设数量。
If all 7 base stations respond to the consent request, the terminal u j selects 6 base stations from the 7 base stations to join the CoMP set. If only 5 of the 7 base stations respond to the consent request, the terminal then adds all 5 base stations to the CoMP set and updates the preset number of CoMP sets.
(2)终端选择候选集合中的几个基站,并向选择的基站同时发送CoMP集合加入请求。(2) The terminal selects several base stations in the candidate set, and sends a CoMP set join request to the selected base stations at the same time.
假设终端u
j的CoMP集合中基站数量的预设数量为10,已经添加到CoMP集合中的基站数为4,还需要再添加6个基站,而候选集合中的尚未发送CoMP集合加入请求的基站的数量为7。这时终端u
j选择候选集合中的6个基站并向这6个基站同时发送CoMP集合加入请求。若6个基站全部同意加入终端u
j的 CoMP集合,则终端确定CoMP集合构建完成,否则,终端更新CoMP集合的预设数量。
Assume that the preset number of base stations in the CoMP set of the terminal u j is 10, the number of base stations that have been added to the CoMP set is 4, and another 6 base stations need to be added, and the base stations in the candidate set that have not yet sent a CoMP set join request The number is 7. At this time, the terminal u j selects 6 base stations in the candidate set and sends a CoMP set join request to the 6 base stations at the same time. If all 6 base stations agree to join the CoMP set of the terminal u j , the terminal determines that the CoMP set is constructed, otherwise, the terminal updates the preset number of CoMP sets.
上述方法,终端无需等待基站的反馈信息,而是直接向候选集合中的基站发送CoMP集合,这样构建CoMP集合的效率高,速度快,但是会对候选集合中的一些基站资源造成浪费。In the above method, the terminal does not need to wait for the feedback information of the base station, but directly sends the CoMP set to the base stations in the candidate set. In this way, the CoMP set is constructed with high efficiency and high speed, but it will waste some base station resources in the candidate set.
方式2、串行发送,即终端向候选集合中的N个基站一个一个的发送CoMP集合加入请求。Method 2: Serial transmission, that is, the terminal sends a CoMP set join request to N base stations in the candidate set one by one.
在终端向候选集合中的基站一个一个的发送CoMP集合加入请求时的顺序可以有很多种,下面列举几种。The sequence in which the terminal sends the CoMP set join request to the base stations in the candidate set one by one can be various, and the following are listed below.
顺序一、按照候选集合中的排序依次发送。Order one: Send them in order according to the order in the candidate set.
假设按信号强度从大到小排序的候选集合中尚未发送CoMP集合加入请求的基站有基站1,基站2,基站3,终端u
j的CoMP集合的空额数为3,此时,终端按照候选集合的顺序依次向基站1,基站2,基站3发送CoMP集合加入请求,在每个基站回复终端u
j之后,再向下一个基站发送CoMP集合加入请求,若基站2,基站3同意加入终端u
j的CoMP集合,基站1拒绝加入终端u
j的CoMP集合,则更新CoMP集合的预设数量为2。
Assume that the base stations that have not yet sent a CoMP set join request among the candidate sets sorted by signal strength are base station 1, base station 2, base station 3, and the number of empty CoMP sets for terminal u j is 3. At this time, the terminal is based on the candidate set. The CoMP set join request is sent to base station 1, base station 2, and base station 3 in sequence. After each base station responds to terminal u j , it sends a CoMP set join request to the next base station. If base station 2, base station 3 agrees to join terminal u j CoMP set, the base station refuses to accede to the terminal 1 u j CoMP set, updating the CoMP set preset number is 2.
顺序二、不按照候选集合中的排序随机发送。The second order is not randomly sent according to the order in the candidate set.
假设按信号强度从大到小排序的候选集合中尚未发送CoMP集合加入请求的基站有基站1,基站2,基站3,终端u
j的CoMP集合的空额数为2,此时,终端可以不按照候选集合的排序,先向基站2发送CoMP集合加入请求,在基站2回复同意加入终端u
j的CoMP集合之后,再向基站1发送CoMP集合加入请求,若基站1同意加入终端u
j的CoMP集合,则终端u
j确定完成CoMP集合的构建,否则,终端u
j向基站3发送CoMP集合加入请求。
Assume that the base stations that have not yet sent CoMP set join requests among the candidate sets sorted by signal strength are base station 1, base station 2, base station 3, and the number of empty CoMP sets of terminal u j is 2. At this time, the terminal may not The candidate set is sorted by first sending a CoMP set join request to base station 2. After base station 2 replies to the CoMP set agreeing to join terminal u j , it sends a CoMP set join request to base station 1. If base station 1 agrees to join the CoMP set of terminal u j , The terminal u j determines to complete the construction of the CoMP set; otherwise, the terminal u j sends a CoMP set joining request to the base station 3.
发送方式二、等到反馈后再发送。Sending method 2: Wait for feedback before sending.
具体的,终端在CoMP集合中的基站数量未达到预设数量时,向候选集合内尚未发送CoMP集合加入请求的基站发送CoMP集合加入请求,且每次只向其中的一个基站发送CoMP集合加入请求,待该基站向终端反馈确定加入或拒绝加入的信息之后,再判断是否向下一个基站发送CoMP集合加入请求。Specifically, when the number of base stations in the CoMP set does not reach the preset number, the terminal sends a CoMP set join request to a base station in the candidate set that has not yet sent a CoMP set join request, and sends a CoMP set join request to only one of the base stations at a time. After the base station feeds back to the terminal information for determining whether to join or refuse to join, it is then determined whether to send a CoMP set join request to the next base station.
上述方法,终端向候选集合中的基站发送CoMP集合加入请求之后需要等待基站的反馈信息,根据反馈信息判断基站是否加入CoMP集合之后才会继续发送CoMP集合加入请求,这种方式下构建CoMP集合的速度会减慢但是使候选集合中的基站资源得到了充分的利用。In the above method, the terminal needs to wait for the feedback information of the base station after sending the CoMP set join request to the base stations in the candidate set, and then determines whether the base station joins the CoMP set according to the feedback information before continuing to send the CoMP set join request. In this way, the CoMP set is constructed. The speed will slow down but the base station resources in the candidate set are fully utilized.
在本申请的某些实施例中,可以预先设置一个候选指针,在终端向候选集合中的基站发送CoMP集合加入请求时,指针指向候选集合内下一个还未发送CoMP集合加入请求的基站。In some embodiments of the present application, a candidate pointer may be set in advance. When the terminal sends a CoMP set join request to a base station in the candidate set, the pointer points to the next base station in the candidate set that has not yet sent a CoMP set join request.
以生成候选列表为例,如图2C所示,pt(u
j)为终端u
j的候选指针,指向终端u
j候选列表内下一个还未发送CoMP集合加入请求的基站。在初始时,CoMP集合为空,pt(u
j)指向候选列表第一个基站BS
1,CoMP集合中基站的最大数目为q(j),终端u
j的候选列表长度为L(j),则e-CoMP(j)=q(j)且cd(j)=L(j),终端在CoMP集合中的基站数目未达到预设数量时,向候选列表内尚未发送CoMP集合加入请求的min{e-CoMP(j),cd(j)}个基站发送CoMP集合加入请求,其中e-CoMP(j)为终端u
j的CoMP集合空额数,cd(j)为终端u
j的候选列表内还未发送CoMP集合加入请求的基站数量。
To generate a candidate list as an example, shown in Figure 2C, Pt (u j) u j is the pointer to the candidate terminal, terminal u point to the next base station has not transmitted a request to join in the CoMP set j candidate list. Initially, the CoMP set is empty, pt (u j ) points to the first base station BS 1 in the candidate list, the maximum number of base stations in the CoMP set is q (j), and the candidate list length of terminal u j is L (j), Then e-CoMP (j) = q (j) and cd (j) = L (j), when the number of base stations of the terminal in the CoMP set does not reach the preset number, the min of the CoMP set joining request has not been sent to the candidate list. {e-CoMP (j), cd (j)} base stations send CoMP set join requests, where e-CoMP (j) is the number of empty CoMP sets of terminal u j , and cd (j) is the candidate list of terminal u j The number of base stations that have not sent a CoMP set join request.
其中min{e-CoMP(j),cd(j)}的取值为e-CoMP(j)或cd(j)。Among them, min {e-CoMP (j), cd (j)} takes the value of e-CoMP (j) or cd (j).
(1)min{e-CoMP(j),cd(j)}的取值为e-CoMP(j)。(1) The value of min {e-CoMP (j), cd (j)} is e-CoMP (j).
若终端u
j的CoMP集合空额数小于或等于终端u
j的候选列表内还未发送 CoMP集合加入请求的基站数量,即:
If the number of empty CoMP sets of terminal u j is less than or equal to the number of base stations in the candidate list of terminal u j that have not yet sent a CoMP set join request, that is:
e-CoMP(j)≤cd(j)e-CoMP (j) ≤cd (j)
则终端u
j向候选指针pt(u
j)指向的基站及后面的基站共e-CoMP(j)个基站发送CoMP集合加入请求。
Then, the terminal u j sends a CoMP set join request to the base stations pointed to by the candidate pointer pt (u j ) and the base stations that follow e-CoMP (j).
假设,终端u
j的CoMP集合的满额数为20,现在的CoMP集合空额数为5,终端u
j的候选列表内还未发送CoMP集合加入请求的基站数量为6,则终端u
j向候选列表内还未发送CoMP集合加入请求的5个基站发送CoMP集合加入请求。
Assume that the full number of CoMP sets of terminal u j is 20, the current empty number of CoMP sets is 5, and the number of base stations in terminal u j 's candidate list that have not yet sent a CoMP set join request is 6, then terminal u j sends a candidate list to the candidate list. The five base stations that have not yet sent a CoMP set join request send a CoMP set join request.
(2)min{e-CoMP(j),cd(j)}取值为cd(j)。(2) The value of min {e-CoMP (j), cd (j)} is cd (j).
若终端u
j的CoMP集合空额数大于候选列表内还未发送CoMP集合加入请求的基站数量,即:
If the number of empty CoMP sets of terminal u j is greater than the number of base stations in the candidate list that have not yet sent CoMP set join requests, that is:
e-CoMP(j)>cd(j)e-CoMP (j) > cd (j)
则终端u
j的候选列表里面尚未发送CoMP集合加入请求的基站即使全部加入到CoMP集合也无法使CoMP集合满额,所以终端u
j向剩余尚未发送CoMP集合加入请求的cd(j)个基站发送CoMP集合加入请求。
Then the base station in the candidate list of the terminal u j that has not yet sent a CoMP set join request cannot make the CoMP set full even if all the base stations have joined the CoMP set. Therefore, the terminal u j sends CoMP to the remaining cd (j) base stations that have not yet sent a CoMP set join request. Collection join request.
假设,终端u
j的CoMP集合的满额数为20,现在的CoMP集合空额数为6,终端u
j的候选列表内还未发送CoMP集合加入请求的基站数量为4,则终端u
j按候选列表顺序向候选列表还未发送CoMP集合加入请求的4个基站发送CoMP集合加入请求。
Assume that the full number of CoMP sets of terminal u j is 20, the current empty number of CoMP sets is 6, and the number of base stations in terminal u j 's candidate list that have not yet sent a CoMP set join request is 4, then terminal u j according to the candidate list The four base stations that have not yet sent the CoMP set join request to the candidate list send the CoMP set join request in order.
为了提高CoMP集合中基站的利用率,在基站接收终端发送的CoMP集合加入请求之后,可以根据公平指数判断是否加入CoMP集合。其中,公平指数可以包括但不限于下列中的部分或全部:终端的性能参数、优先级。In order to improve the utilization rate of the base stations in the CoMP set, after the base station receives the CoMP set join request sent by the terminal, it can determine whether to join the CoMP set according to the fairness index. The fairness index may include, but is not limited to, some or all of the following: the terminal's performance parameters and priorities.
下面分别以终端的性能参数和优先级为例对判断是否加入CoMP集合的 内容进行介绍。The following describes the content of judging whether to join the CoMP set by taking terminal performance parameters and priorities as examples.
方案一,终端的性能参数可以是接收功率或传输速率。In solution 1, the performance parameter of the terminal may be received power or transmission rate.
1、终端的性能参数是终端发送的参考信号在基站处的接收功率;1. The performance parameter of the terminal is the received power of the reference signal sent by the terminal at the base station;
依据终端u
j的参考信号在基站BS
i的接收功率pu
ji判断基站是否加入CoMP集合,如果终端u
j的参考信号在基站BS
i的接收功率pu
ji大于功率阈值,则加入CoMP集合;否则,不加入CoMP集合。
According to the reference signal terminal u j is the received power pu base station BS i is ji is determined whether the base station is added CoMP set, if the terminal u j of the reference signal received power pu ji in the base station BS i is greater than the power threshold, then added CoMP set; otherwise, Do not join the CoMP collection.
上述方法,终端u
j向基站BS
i发送的CoMP集合加入请求只包含终端u
j的参考信号在基站BS
i的接收功率pu
ji,不需要附带其他信息,减少了信令交互时延,降低了系统的复杂度。
In the above method, the CoMP set join request sent by the terminal u j to the base station BS i only includes the received power pu ji of the reference signal of the terminal u j at the base station BS i , and no additional information is required, which reduces the signaling interaction delay and reduces The complexity of the system.
2、终端的性能参数是终端请求的传输速率;2. The performance parameter of the terminal is the transmission rate requested by the terminal;
依据终端u
j的参考信号的传输速率ru
j判断基站是否加入CoMP集合,如果终端u
j的参考信号的传输速率ru
j大于速率阈值,则加入CoMP集合;否则,不加入CoMP集合。
A reference signal based on the transmission rate of terminal u j j determines whether a base station added to Ru CoMP set, if the transmission rate of the terminal reference signal u j j Ru is greater than the rate threshold, then added CoMP set; otherwise, without the addition of CoMP set.
上述方法,终端u
j向基站BS
i发送的CoMP集合加入请求包含终端u
j的参考信号的传输速率ru
j,不需要附带其他信息,减少了信令交互时延,降低了系统的复杂度。
In the above method, the CoMP set join request sent by the terminal u j to the base station BS i includes the transmission rate ru j of the reference signal of the terminal u j without additional information, which reduces the signaling interaction delay and the system complexity.
方案二,优先级为终端在通信运营商的通信优先级。In the second solution, the priority is the communication priority of the terminal in the communication operator.
终端在通信运营商的通信优先级可以有运营商设置,终端u
j的通信优先级越高,终端与基站间连接的建立更有优势,从而可以提高了资源利用率。
Terminal operators may have provided in the communication carrier's communication priorities, communication terminal u j higher priority, the establishment of an advantage between the terminal and base station connection, which can improve resource utilization.
依据终端在通信运营商的通信优先级判断基站是否加入CoMP集合,如果终端在通信运营商的通信优先级大于优先级阈值,则加入CoMP集合;否则,不加入CoMP集合。Determine whether the base station joins the CoMP set according to the communication priority of the terminal at the communication operator. If the communication priority of the terminal at the communication operator is greater than the priority threshold, it joins the CoMP set; otherwise, it does not join the CoMP set.
在实施中,根据终端的性能参数和/或优先级判断基站是否加入CoMP集合,使得终端与基站间连接的建立更有优势,保证终端与基站间连接的公平 性,避免由于终端与基站间不公平的连接导致资源匮乏或资源浪费。In implementation, judging whether the base station joins the CoMP set according to the terminal's performance parameters and / or priorities makes the establishment of the connection between the terminal and the base station more advantageous, guarantees the fairness of the connection between the terminal and the base station, and avoids Fair connections lead to scarce resources or wasted resources.
上述方法,通过生成公平指数,根据公平指数判断基站是否加入CoMP集合,使得在周围终端连接程度复杂时,构建的CoMP集合中的基站资源更加有效。In the above method, by generating a fairness index and judging whether the base station joins the CoMP set according to the fairness index, when the connection degree of surrounding terminals is complicated, the base station resources in the constructed CoMP set are more effective.
本申请实施例中,基站判断所述公平指数是否大于指数阈值;如果是,则所述基站确定加入CoMP集合,通知所述终端同意加入CoMP集合;否则,所述基站确定不加入CoMP集合,通知所述终端拒绝加入CoMP集合。In the embodiment of the present application, the base station determines whether the fairness index is greater than the index threshold; if so, the base station determines to join the CoMP set and notifies the terminal to agree to join the CoMP set; otherwise, the base station determines not to join the CoMP set and notifies The terminal refuses to join the CoMP set.
假设,基站BS
i计算出终端u
j的公平指数为FI
i(u
j),自身的公平指数阈值为FI-TH
i:
Assume that the base station BS i calculates the fairness index of the terminal u j as FI i (u j ), and its own fairness index threshold is FI-TH i :
若FI
i(u
j)≥FI-TH
i,则基站BS
i确定加入CoMP集合,通知终端u
j同意加入CoMP集合;否则,基站BS
i确定不加入CoMP集合,通知终端u
j拒绝加入CoMP集合。
If FI i (u j ) ≥FI-TH i , the base station BS i determines to join the CoMP set, and notifies the terminal u j of agreeing to join the CoMP set; otherwise, the base station BS i determines not to join the CoMP set, and notifies the terminal u j of refusing to join the CoMP set. .
本申请实施例中,所述终端从返回同意加入CoMP集合的基站中选择至少一个基站加入到CoMP集合中之后,需要判断CoMP集合中的基站数目是否达到预设数量,来决定是否继续向候选集合中的基站发送CoMP集合加入请求。In the embodiment of the present application, after the terminal selects at least one base station from the base stations that have returned to agree to join the CoMP set to join the CoMP set, it needs to determine whether the number of base stations in the CoMP set reaches a preset number to determine whether to continue to the candidate set. The base station in the network sends a CoMP set join request.
如果是,则终端完成构建CoMP集合,否则,终端继续向候选列表中的基站发送CoMP集合加入请求。If so, the terminal finishes building the CoMP set; otherwise, the terminal continues to send a CoMP set join request to the base station in the candidate list.
本申请实施例中,所述终端从返回同意加入CoMP集合的基站中选择至少一个基站加入到CoMP集合之后,将加入到CoMP集合的基站以及拒绝加入CoMP集合的基站从所述候选集合中删除。In the embodiment of the present application, after the terminal selects at least one base station from the base stations that return to join the CoMP set to join the CoMP set, the terminal deletes the base stations added to the CoMP set and the base stations that refuse to join the CoMP set from the candidate set.
假设,有ck(j)个基站给终端u
j回复同意请求,则回复同意请求的ck(j)个基站编号被添加到终端u
j的CoMP集合,代表这ck(j)个基站加入终端u
j的CoMP集合,然后将这些基站从候选集合中删除,将回复拒绝请求的基站直接 将这个基站从候选集合中删除,不改变终端u
j的CoMP集合。
Suppose there ck (j) base stations to the terminals u j reply to grant the request, then the reply ck (j) approve the request of a base station number is added to the terminal u j CoMP set, represent this ck (j) base stations added to terminal u The CoMP set of j is then deleted from the candidate set. The base station that responds to the rejection request directly deletes this base station from the candidate set without changing the CoMP set of terminal u j .
在本申请的某些实施例中,终端也可以直接在向候选集合中的基站发送CoMP集合加入请求之后将发送CoMP集合加入请求的基站从候选集合中删除,不需要等待基站回复请求,这种情况下可以减少基站与终端之间的信令交互,降低信令开销。In some embodiments of the present application, the terminal may also directly delete the base station that sends the CoMP set join request from the candidate set after sending the CoMP set join request to the base stations in the candidate set, without waiting for the base station to respond to the request. In this case, signaling interaction between the base station and the terminal can be reduced, and signaling overhead can be reduced.
在终端移动时需要判断是否需要更新CoMP集合,但是判断的过程比较复杂,必须由CAMF(Coordination Area Management Function,协作区域管理功能)等新功能单元收集基站与终端信息确定是否需要更新CoMP集合,而本申请实施例中通过信号强度就可以判决,不需要CAMF等新功能单元。When the terminal moves, it is necessary to determine whether the CoMP set needs to be updated, but the determination process is more complicated. New functional units such as CAMF (Coordination Area Management Function) must be used to collect base station and terminal information to determine whether the CoMP set needs to be updated. In the embodiment of the present application, a decision can be made based on signal strength, and no new functional unit such as CAMF is required.
在实施中,终端从返回同意加入CoMP集合的基站中选择至少一个基站加入到CoMP集合中,还需要判断CoMP集合中特殊基站的数量是否达到设定第二阈值。In implementation, the terminal selects at least one base station from the base stations that have returned to agree to join the CoMP set to join the CoMP set, and further needs to determine whether the number of special base stations in the CoMP set reaches a set second threshold.
其中,所述特殊基站的判定方式有很多种,下面列举几种:There are many types of determination methods for the special base station, and several are listed below:
判定方式一、判断CoMP集合中基站的信号强度是否小于所述候选集合中基站的最小信号强度。Judgment Method 1: Determine whether the signal strength of the base stations in the CoMP set is less than the minimum signal strength of the base stations in the candidate set.
若CoMP集合中基站的信号强度小于所述候选集合中基站的最小信号强度,且差值达到第三阈值,则该基站为特殊基站,否则,该基站不是特殊基站。If the signal strength of the base station in the CoMP set is less than the minimum signal strength of the base station in the candidate set, and the difference reaches a third threshold, the base station is a special base station; otherwise, the base station is not a special base station.
判定方式二、判断CoMP集合中基站的信号强度是否小于信号强度阈值。Judgment method 2: Determine whether the signal strength of the base station in the CoMP set is less than the signal strength threshold.
可以预先设置一个信号强度阈值,判断CoMP集合中基站的信号强度是否小于该阈值,如果是,则该基站为特殊基站,否则,该基站不是特殊基站。A signal strength threshold may be set in advance to determine whether the signal strength of the base station in the CoMP set is less than the threshold. If it is, the base station is a special base station; otherwise, the base station is not a special base station.
上述方法,预先设定阈值,通过判断阈值与信号强度之间的关系来确定特殊基站,由于特殊基站的限制,使得对于终端小范围的移动,不会更新CoMP集合,提高了CoMP集合的构建效率。In the above method, a threshold is set in advance, and a special base station is determined by judging the relationship between the threshold and the signal strength. Due to the limitation of the special base station, the CoMP set is not updated for small-scale movement of the terminal, which improves the construction efficiency of the CoMP set. .
具体的,所述终端从返回同意加入CoMP集合的基站中选择至少一个基站加入到CoMP集合之后,需要判断CoMP集合中特殊基站的数量是否达到 设定第二阈值,如果是,则所述终端清空CoMP集合;否则,终端判断CoMP集合中基站数目是否达到预设数量。Specifically, after the terminal selects at least one base station from the base stations that have returned to agree to join the CoMP set to join the CoMP set, it needs to determine whether the number of special base stations in the CoMP set reaches a set second threshold, and if so, the terminal is emptied. CoMP set; otherwise, the terminal determines whether the number of base stations in the CoMP set reaches a preset number.
在终端的空间位置与信道状态没有发生太大变化的情况下,CoMP集合建完成之后不改变。如果发生较大变化,即CoMP集合中部分基站的信号强度远小于候选集合中基站的信号强度,即特殊基站的数量达到设定第二阈值,则清空CoMP集合,刷新候选集合,重新构建CoMP集合。这样可以及时更新CoMP集合,在终端发生移动时,其CoMP集合也会更新,可以应对终端的移动。In the case where the spatial position of the terminal and the channel state do not change much, the CoMP set does not change after the completion. If a large change occurs, that is, the signal strength of some base stations in the CoMP set is much smaller than the signal strength of the base stations in the candidate set, that is, the number of special base stations reaches a set second threshold, the CoMP set is cleared, the candidate set is refreshed, and the CoMP set is rebuilt .
