[0045] 本发明实施例提供了一种设备发射功率控制的方法,如图2所示,所述方法包括如下步骤: [0045] The embodiment provides a method of transmission power control apparatus of the present invention as shown in FIG. 2, the method comprising the steps of:

[0046] 201、发送设备获取接入设备发送的通信资源的干扰敏感程度信息(High Interference Indication, HII)以及干扰过载禾呈度信息(Overload Indication, 01)。 [0046] 201, the access device obtains the interference transmitting apparatus transmits a communication resource sensitivity information (High Interference Indication, HII) and interference overload level information was Wo (Overload Indication, 01).

[0047] 本实施例中D2D设备自主选择通信资源,选择通信资源的依据为接入设备发送的干扰敏感程度信息以及干扰过载程度信息。 [0047] The embodiment according to the present apparatus to choose D2D communication resource, selecting a communication resource for the access interference embodiment the sensitivity of the information transmitted over the degree of interference and information overload. 接入设备将其管辖内所有用户的通信资源的干扰敏感信息以及干扰过载信息下发给发送设备。 The transmitting device sent the access device will interfere with communication resources for all users within its jurisdiction sensitive information and the interference information overload. 例如,把所有通信资源的干扰敏感程度信息和干扰过载程度信息,以bitmap的形式下发给发送设备,bitmap列表中的第0位赋值第一个通信资源的干扰敏感信息,第1位赋值第二个通信资源的干扰敏感信息,以此类推。 For example, the interfering communication resources all sensitive information and the interference information over the degree of overload, under the form of a bitmap in a distributed transmitting apparatus, the interference sensitive information bit 0 first communication resource assignment bitmap list, the assignment of bit 1 interfere with communication resources of two sensitive information, and so on. 每一bit位有0和1两种状态,0状态代表干扰敏感1状态代表干扰不敏感,或者1状态代表干扰敏感0状态代表干扰不敏感。 Each bit position has two states 0 and 1, a 0 state represents a state representative of the interference sensitive insensitive to interference, the interference state represents 1 or 0 state represents a sensitive insensitive to interference. 将所有通信资源的干扰敏感信息以bitmap列表的形式发送给发送设备。 The interference of all communication resources sensitive information to the transmission device in the form of bitmap list. 干扰过载信息可以以相同的形式下发给发送设备,此处不再赘述。 Interference overload information can be sent to the transmitting device to the same form, it will not be repeated here.

[0048] 202、发送设备确定与接收设备通信时所使用的通信资源。 [0048] 202, communication resources when transmitting and receiving communication device determines that the equipment used.

[0049] 发送设备获取到通信资源的干扰敏感程度信息以及干扰过载程度信息的bitmap 列表后,根据该bitmap列表选择抗干扰能力最强的通信资源进行通信。 [0049] After obtaining the communication resource interference sensitivity information transmitting apparatus and an interference level of the carrier through the bitmap list information, communicating the selected list of the strongest interference bitmap communication resources according to capability.

[0050] 具体的,发送设备根据干扰敏感程度信息的bitmap列表选择出一个或多个干扰不敏感的通信资源,然后根据干扰过载程度信息的bitmap列表选择出一个或多个干扰不过载的通信资源。 [0050] Specifically, the transmitting apparatus selected according to the sensitivity of the interference bitmap list information is not sensitive to the one or more interfering communication resources, then according to the interference degree through the bitmap list information contained in one or more selected interfering communication resources but contained . 将干扰不敏感的通信资源和干扰不过载的通信资源分别作为一个选择子集,然后取两选择子集的交集,即选择出干扰不敏感并且干扰不过载的通信资源。 Interference insensitive communication resource and communication resources interference but as a carrier are selected subset, then take the intersection of two selected subsets, i.e. selected but insensitive to interference and the interference of communication resources carrier.

[0051] 如果所述交集的通信资源多于一条,则发送设备在所述交集中随机选择一条作为与接收设备通信所使用的通信资源;如果所述交集为空,则发送设备执行步骤201,重新获取通信资源的干扰敏感程度信息以及干扰过载程度信息,再次进行选择,直到所述子集的交集不为空为止。 [0051] If the communication resource than an intersection, the intersection of the transmitting apparatus in communication resources a randomly selected as a receiving apparatus used; if the intersection is empty, the transmission device 201 performs the steps, regain communication resources and interference sensitivity information overload interference overload level of information to choose again until the subset until the intersection is not empty.

[0053] 此外还需强调的是,实际应用中用来表示通信资源干扰程度的信息不限于本发明实施例中所述的干扰敏感程度信息或干扰过载程度信息,并且所述通信资源干扰程度的信息还可通过其他形式下发给发送设备。 [0053] Further needs to be emphasized that the practical application is used to indicate the degree of interference of communication resource information is not limited interference embodiment sensitivity information or interference information according to the degree of overload embodiment of the present invention, the degree of interference and communication resources other forms of information may also be sent by the transmitting device. 通过其他形式下发时,所述通信资源干扰程度的信息不限于上述干扰敏感、干扰不敏感或干扰过载、干扰不过载两种状态,可以根据其干扰程度划分若干等级已进行更为细致的划分和选择。 Issued through other forms, the degree of interference of the communication resource information is not limited to the above interference sensitive insensitive to interference or interference overload, but contained two kinds of interference condition may already be a more detailed classification is divided according to the degree of interference several levels of and choose.

[0056] 需要说明的是,接入设备将通信资源划分为高、中、低三个干扰程度等级,接入设备根据通信资源的干扰程度等级计算在该干扰程度等级上能够接受的最大干扰信号功率, 然后将该最大干扰信号功率发送给发送设备。 [0056] Incidentally, the access device to the communication resources are divided into high, medium and low level of the degree of interference, the access device in accordance with the degree of interference level calculation communication resources to accept the degree of interference on the maximum level of the interfering signal power, then the maximum transmit power of the interference signal to the transmission device.

[0058] 接入设备向发送设备发送参考信号序列的目的在于使发送设备根据该参考信号序列计算发送设备到接入设备的路损,参考信号序列的内容本身并无意义。 [0058] The object of the access device transmits a reference signal sequence to a transmitting device that transmits the transmission device to the device-access device loss is calculated according to the reference signal sequence, it does not have significance content of the reference signal sequence. 所述发送设备到接入设备的路损为在发送设备到接入设备之间路径上的发射功率损耗值。 The channel transmission device to an access device to transmit power loss on a path loss value between the transmitting device to the access device.

[0059] 205、发送设备计算发送设备到接入设备的路损。 [0059] 205, the transmitting device transmits to the computing device access device path loss.

[0060] 发送设备接收到接入设备发送的参考信号序列后,能够计算出接收参考信号序列的参考信号序列接收功率,接入设备发送参考信号序列的参考信号序列发射功率由接入设备配置并下发给发送设备,所以发送设备到接入设备的路损就等于接入设备发送参考信号序列的参考信号序列发射功率与发送设备接收参考信号序列的参考信号序列接收功率之差。 [0060] The transmitting device receives the reference signal sequence sent by the access device, the reference signal sequence can be calculated reception power of the reference signal sequence, the access device transmits the reference signal sequence transmit power of a reference signal sequence configured by the access device, and the distributed transmitting apparatus, the transmitting device to the access device path loss is equal to the reference signal sequence transmitted power transmitting device transmits a reference signal sequence of the access device receiving a reference signal sequence difference between the reference signal sequence received power.

[0061] 206、发送设备计算在该通信资源上的最大发射功率。 [0061] 206, the transmitting device over the communication resource calculates maximum transmission power.

[0065] 208、发送设备计算发送设备到接收设备的路损。 [0065] 208, the transmitting device transmits to the receiving device calculates the path loss device.

[0066] 接收设备发送信标帧的目的在于使发送设备根据该信标帧计算出发送设备到接收设备之间的路损。 [0066] The object of the receiving device transmits a beacon frame that the transmission apparatus is calculated based on the beacon frame transmitting device to a path loss between the receiving device. 具体的,发送设备接收到信标帧后计算接收信标帧的信标帧接收功率, 然后用信标帧中携带的接收设备发送该信标帧的信标帧发射功率减去所述信标帧接收功率即为接收设备到发送设备的路损,以该路损近似作为发送设备到接收设备的路损。 Specifically, the sending computing device receives the beacon frame received beacon frame after beacon frame received power signal, and then transmits a beacon frame transmit power of the beacon frame reception apparatus beacon frame carries subtracting the beacon frame received power is the path loss to the receiving device the transmission device, the path loss to approximately a transmission device to a receiving device path loss.

[0067] 需要说明的是,本步骤中的信标帧发射功率与信标帧接收功率是针对接收设备发送信标帧而言的,与本发明中进行功率控制的发射功率无关。 [0067] Incidentally, the transmission power of beacon frame received power of the beacon frame in this step is for the purposes of the receiving device transmits a beacon frame, regardless of the transmission power of the power control of the present invention. 同样步骤204和步骤205中的参考信号序列发射功率和参考信号序列接收功率是针对参考信号序列而言的,同样与本发明中进行功率控制的发射功率无关。 The same step reference signal sequence transmit power and the received power of the reference signal sequences in steps 204 and 205 are for purposes of reference signal sequence, the same transmit power regardless of the power control of the present invention.

[0068] 209、发送设备计算在该通信资源上的最小发射功率。 [0068] 209, the transmitting device over the communication resource computing the minimum transmission power.

[0069] 所述最小发射功率为发送设备到接收设备的路损与接收设备的最小接收功率之和。 [0069] The minimum received power to the minimum transmit power transmitting device to a receiving device path loss and the receiving device.

[0070] 所述接收设备的最小接收功率为接收设备能够正确接收信号所需的最小接收功率。 [0070] The minimum received power receiving device is a receiving apparatus capable of receiving the minimum received power of the desired signal correctly.

[0071] 210、发送设备根据最大发射功率和最小发射功率,选择与接收设备通信时所使用的发射功率。 [0071] 210, the transmit power transmitting apparatus according to the maximum transmit power of the communication and the minimum transmit power, selecting a receiving device used.

[0072] 具体的,发送设备将步骤206和步骤209中计算的最大发射功率和最小发射功率进行比较: [0072] Specifically, the maximum transmission power of the transmission device 209 calculated in step 206 and the minimum transmit power and the step of comparing:

[0073] 当最大发射功率大于最小发射功率时,在所述最大最小发射功率的数值区间内任选一个功率作为与接收设备进行通信所使用的发射功率。 [0073] When the maximum transmit power is greater than the minimum transmission power, optionally as a power receiving device within the numerical range of the maximum and minimum transmit power of the transmission power used for communication.

[0074] 当最大发射功率等于最小发射功率时,将所述最大发射功率或者最小发射功率作为与接收设备进行通信所使用的发射功率。 [0074] When the maximum transmit power is equal to the minimum transmission power, the maximum transmit power or the minimum transmission power and the reception device as a transmission power used for communication.

[0075] 当最大发射功率小于最小发射功率时,功率选择失败,重新执行步骤201至步骤210,选择新的通信资源并计算重新选择的通信资源上的最大发射功率和最小发射功率。 [0075] When the maximum transmit power is less than the minimum transmission power, the power selection fails, re-executes step 201 to step 210, selects a new communication resource and calculates the maximum transmit power on the reselected communication resource and the minimum transmission power.

[0076] 需要说明的是,最大发射功率值与接入设备能够接受的最大干扰信号功率值相关,而接入设备能够接受的最大干扰信号功率值因通信资源质量的不同而不同;同样,最小发射功率值与发送设备到接收设备的路损值相关,而发送设备到接收设备的路损值因通信资源质量的不同而不同。 [0076] Incidentally, the maximum transmission power value and the access device capable of accepting a maximum interference signal power values ​​associated, the access device can accept a maximum interference signal power value of the communication quality due to the different resources are different; Similarly, the minimum transmission power value and the transmission device to the reception device path loss correlation value, the device transmits to the receiving device path loss due to communication quality different resources are different. 由此会出现最大发射功率小于最小发射功率的情况。 Whereby the maximum transmit power is less than the minimum transmission power appears. 出现此情况时,发送设备所选择的通信资源无法利用,需要重新选择通信资源,并根据新的通信资源计算最大最小发射功率。 When this occurs, the communication resource for transmitting the selected device can not be used, need to select a communication resource, and calculates the maximum and minimum transmission power according to the new communication resource.

[0077] 优选的,当发送设备选择好一个发射功率并根据该发射功率与接收设备开始进行通信后,会继续接收接收设备发送的信标帧。 [0077] Preferably, when the transmitting apparatus selects a better transmission power and starts communication based on the transmission power and the reception apparatus, reception continues to receive a beacon frame transmitted by the device. 该信标帧中携带有功率调整参数,发送设备根据该功率调整参数调整发射功率的大小。 The beacon frame carries the power adjustment parameters, the magnitude of the power transmission device transmit power adjustment parameter based.

[0078] 具体的,当接收设备接收信号的接收功率小于其能够正确接收该信号的最小功率时,接收设备会在发送的信标帧中携带功率调整参数给发送设备,要求发送设备提高发射功率。 [0078] Specifically, when receiving the power receiving device receiving signal is less than that capable of receiving the minimum power of the signal properly, the receiving apparatus carries power adjustment parameter to the transmission device in the beacon frame transmitted, it requires transmission apparatus to improve the transmission power . 发送设备根据该功率调整参数提高发射功率,以保证接收设备能够正确接收信号。 Increase the transmission power of the transmission device according to the power adjustment parameter to ensure that the receiving device can receive signals correctly. 或者,当发射功率过大时,虽然该发射功率未超过最大发射功率,但出于减少设备功耗,提高电池续航能力的目的,接收设备会要求发送设备降低发射功率。 Alternatively, when the transmission power is too large, although the transmitting power does not exceed the maximum transmit power, but the equipment for reducing the power consumption and improve battery life of the object, the receiving apparatus can reduce the transmission power requirements of the transmission device. 发送设备根据该功率调整参数,在保证接收功率不低于接收设备能够正确接收信号的最低接收功率的前提下,降低发射功率。 The premise of the transmission device to the power adjustment parameter, the received power is not less than the minimum guaranteed reception power of a signal receiving apparatus capable of receiving correct, reduce transmit power.

[0079] 进一步优选的,当发送设备选择好一个发射功率并根据该发射功率与接收设备开始进行通信后,仍旧会根据通信资源的条件,调整通信资源。 [0079] Further preferably, a good choice when the transmitting apparatus starts the transmission power and the transmitting power according to communication with the receiving apparatus, the communication resource will still be in accordance with the conditions adjusted communication resource.

[0080] 具体的,发送设备接收接入设备发送的通信资源的干扰敏感程度信息以及干扰过载程度信息的bitmap列表,如果根据新bitmap列表选择出来的通信资源的抗干扰能力强于目前所使用的通信资源时,发送设备选择所述新的通信资源作为与接收设备进行通信所使用的通信资源,根据新通信资源的条件重新计算最大发射功率以及最小发射功率并确定一个新的发射功率。 [0080] Specifically, the transmitting apparatus receives the access apparatus interfering communication resources and transmitting the sensitivity of the information contained in the interference degree through the bitmap list information, if stronger than currently used according to the anti-interference ability of the new bitmap list selected communication resource when communication resources, the transmitting device selects a new communication resource as a receiving device for a communication resource used for communication, the maximum transmit power and recalculates the minimum transmit power based on the new communication resource conditions and determine a new transmit power.

[0081] 需要说明的是,上述所述发送设备与所述接收设备同质,都为UE。 [0081] Incidentally, the above-described transmitting device and the receiving device homogeneity are UE. 在本实施例中, 将发射信号的UE作为发送设备、将接收信号的UE作为接收设备,仅为便于表述,实际D2D 应用中,UE之间进行交互式通信,每一部UE都既为发送设备又为接收设备。 In the present embodiment, the UE transmits the signal as a transmission device, the UE receives a signal as a reception apparatus, only ease of description, the practical application D2D, the interactive communication between the UE, each UE are both part of the transmission device but also for the receiving device.

[0093] 发送设备获取到通信资源的干扰敏感程度信息以及干扰过载程度信息的bitmap 列表后,根据该bitmap列表选择抗干扰能力最强的通信资源进行通信。 [0093] After obtaining the communication resource interference sensitivity information transmitting apparatus and an interference level of the carrier through the bitmap list information, communicating the selected list of the strongest interference bitmap communication resources according to capability.

[0094] 具体的,发送设备根据干扰敏感程度信息的bitmap列表选择出一个或多个干扰不敏感的通信资源,然后根据干扰过载程度信息的bitmap列表选择出一个或多个干扰不过载的通信资源。 [0094] Specifically, the transmitting apparatus selected according to the sensitivity of the interference bitmap list information is not sensitive to the one or more interfering communication resources, then according to the interference degree through the bitmap list information contained in one or more selected interfering communication resources but contained . 将干扰不敏感的通信资源和干扰不过载的通信资源分别作为一个选择子集,然后取两选择子集的交集,即选择出干扰不敏感并且干扰不过载的通信资源。 Interference insensitive communication resource and communication resources interference but as a carrier are selected subset, then take the intersection of two selected subsets, i.e. selected but insensitive to interference and the interference of communication resources carrier.

[0095] 如果所述交集的通信资源多于一条,则发送设备在所述交集中随机选择一条作为与接收设备通信所使用的通信资源;如果所述交集为空,则发送设备执行步骤301,重新获取通信资源的干扰敏感程度信息以及干扰过载程度信息,再次进行选择,直到所述子集的交集不为空为止。 [0095] If the communication resource than an intersection, the intersection of the transmitting apparatus in communication resources a randomly selected as a receiving apparatus used; if the intersection is empty, the transmission apparatus 301 executes step, regain communication resources and interference sensitivity information overload interference overload level of information to choose again until the subset until the intersection is not empty.

[0096] 需要强调的是,本实施例中提及的通信资源包括正在与接入设备进行数据通信的通信资源,也包括闲置的通信资源。 [0096] It is emphasized that, in the embodiment mentioned communication resources comprises communication resources of the present embodiment is in data communication with the access device also includes a communication resource idle. 不论通信资源是否闲置,其抗干扰能力都会体现在干扰敏感程度信息以及干扰过载程度信息中,发送设备根据通信资源的干扰敏感程度信息以及干扰过载程度信息选择复用的通信资源,对通信资源闲置与否不作区分。 Regardless of the communication resources are idle and anti-jamming capability will be reflected in the interference sensitivity information and interference overload level of overload information, the transmitting device sensitive information, and interference by selecting the multiplexed communication resource level of the carrier of information, communication resources idle based on the interference communication resources or not does not make a distinction.

[0097] 此外还需强调的是,实际应用中用来表示通信资源干扰程度的信息不限于本发明实施例中所述的干扰敏感程度信息或干扰过载程度信息,并且所述通信资源干扰程度的信息还可通过其他形式下发给发送设备,而且通过其他形式下发时,所述通信资源干扰程度的信息不限于上述干扰敏感、干扰不敏感或干扰过载、干扰不过载两种状态,可以根据其干扰程度划分若干等级已进行更为细致的划分和选择。 [0097] Further needs to be emphasized that the practical application is used to indicate the degree of interference of communication resource information is not limited interference embodiment sensitivity information or interference information according to the degree of overload embodiment of the present invention, the degree of interference and communication resources other forms of information may also be sent by the transmission device, but also through other forms when the hair, the degree of interference of the communication resource information is not limited to the above interference sensitive insensitive to interference or interference overload, but interference contained two states, according to the degree of interference has been divided into several levels of a more detailed classification and selection. [0098] 303、发送设备接收接入设备在选择的通信资源上能够接受的最大干扰信号功率。 [0098] 303, the access device receives a transmission on a communication resource selection apparatus capable of accepting a maximum interference signal power.

[0099] 发送设备选择好与接收设备通信所使用的通信资源后,由接收设备接收接入设备在该通信资源上能够接受的最大干扰信号功率。 [0099] After sending the device a good choice with the communication resources used by the receiving device, the receiving device receives an access device over the communication resource can accept a maximum interference signal power. 此能够接受的最大干扰信号功率为接入设备计算出的接入设备在该通信资源上能够接受的最大干扰信号功率。 A maximum interference signal power can be the maximum acceptable for this interference signal power calculated for the access device in the access device over the communication resource can accept. 发送设备接收所述最大干扰信号功率是为后续计算最大发射功率做准备。 The transmitting device receives a maximum interference signal power is calculated in preparation for the subsequent maximum transmission power.

[0100] 需要说明的是,接入设备将的通信资源划分为高、中、低三个干扰程度等级,接入设备根据通信资源的干扰程度等级计算在该干扰程度等级上的最大干扰信号功率,然后将该能够接受的最大干扰信号功率发送给接收设备,并由接收设备发送给发送设备。 [0100] Incidentally, the access device is divided communication resources is high, medium or low level of the degree of interference, the access device the maximum level of interference on the level of interference signal power based on the interference level calculation the degree of communication resources , then the maximum transmit power of the interfering signal to the receiving apparatus capable of receiving, by the transmitting and receiving apparatus to the transmitting apparatus.

[0101 ] 本实施例中,发送设备无需与接入设备进行通信,所以与步骤301相同,所述最大干扰信号功率也由接收设备从接入设备获取,然后发送给发送设备。 [0101] In this embodiment, the transmitting device need not communicate with the access device, the same as step 301, the maximum interference signal power is also acquired from the access device by the receiving device, then transmitting to the transmitting device.

[0104] 接入设备向接收设备发送参考信号序列的目的在于使接收设备根据该参考信号序列计算接收设备到接入设备的路损,参考信号序列的内容本身并无意义。 [0104] wherein the access device transmits the reference signal sequence to the target receiving apparatus, the receiving apparatus calculates path loss to the receiving apparatus the access device based on the reference signal sequence, does not have significance content of the reference signal sequence.

[0105] 接收设备接收到接入设备发送的参考信号序列后,能够计算出接收参考信号序列的参考信号序列接收功率,接入设备发送参考信号序列的参考信号序列发射功率由接入设备配置并下发给接收设备,所以接收设备到接入设备的路损就等于接入设备发送参考信号序列的参考信号序列发射功率与接收设备接收参考信号序列的参考信号序列接收功率之差。 [0105] After the receiving device receives the reference signal sequence sent by the access device, the reference signal sequence can be calculated reception power of the reference signal sequence, the access device transmits the reference signal sequence transmit power of a reference signal sequence configured by the access device, and next to the receiving device, the receiving device to access the device path loss is equal to the reference signal sequence transmit power and the receiving apparatus transmits a reference signal sequence of the access device receiving a reference signal sequence difference between the reference signal sequence received power.

[0113] 需要说明的是,本步骤中的信标帧发射功率与信标帧接收功率是针对接收设备发送信标帧而言的,与本发明中进行功率控制的发射功率无关。 [0113] Incidentally, the transmission power of beacon frame received power of the beacon frame in this step is for the purposes of the receiving device transmits a beacon frame, regardless of the transmission power of the power control of the present invention. 同样步骤304中的参考信号序列发射功率和参考信号序列接收功率是针对参考信号序列而言的,同样与本发明中进行功率控制的发射功率无关。 Also in step 304 the reference signal sequence transmit power and the received power of the reference signal sequences are, the same transmit power regardless of the power control according to the present invention for a reference signal sequences.

[0121] 当最大发射功率小于最小发射功率时,功率选择失败,重新执行步骤301至步骤309,选择新的通信资源并计算重新选择的通信资源上的最大发射功率和最小发射功率。 [0121] When the maximum transmit power is less than the minimum transmission power, the power selection fails, re-executes step 301 to step 309, selects a new communication resource and calculates the maximum transmit power on the reselected communication resource and the minimum transmission power.

[0122] 需要说明的是,最大发射功率值与接入设备能够接受的最大干扰信号功率值相关,而接入设备能够接受的最大干扰信号功率值因通信资源质量的不同而不同;同样,最小发射功率值与发送设备到接收设备的路损值相关,而发送设备到接收设备的路损值因通信资源质量的不同而不同。 [0122] Incidentally, the maximum transmission power value and the access device capable of accepting a maximum interference signal power values ​​associated, the access device can accept a maximum interference signal power value of the communication quality due to the different resources are different; Similarly, the minimum transmission power value and the transmission device to the reception device path loss correlation value, the device transmits to the receiving device path loss due to communication quality different resources are different. 由此会出现最大发射功率小于最小发射功率的情况。 Whereby the maximum transmit power is less than the minimum transmission power appears. 出现此情况时,发送设备所选择的通信资源无法利用,需要重新选择通信资源,并根据新的通信资源计算最大最小发射功率。 When this occurs, the communication resource for transmitting the selected device can not be used, need to select a communication resource, and calculates the maximum and minimum transmission power according to the new communication resource.

[0123] 优选的,当发送设备选择好一个发射功率并根据该发射功率与接收设备开始进行通信后,会继续接收接收设备发送的信标帧。 [0123] Preferably, when the transmitting apparatus selects a better transmission power and starts communication based on the transmission power and the reception apparatus, reception continues to receive a beacon frame transmitted by the device. 该信标帧中携带有功率调整参数,发送设备根据该功率调整参数调整发射功率的大小。 The beacon frame carries the power adjustment parameters, the magnitude of the power transmission device transmit power adjustment parameter based.

[0124] 具体的,当接收设备接收信号的接收功率小于其能够正确接收该信号的最小功率时,接收设备会在发送的信标帧中携带功率调整参数给发送设备,要求发送设备提高发射功率。 [0124] Specifically, when receiving the power receiving device receiving signal is less than that capable of receiving the minimum power of the signal properly, the receiving apparatus carries power adjustment parameter to the transmission device in the beacon frame transmitted, it requires transmission apparatus to improve the transmission power . 发送设备根据该功率调整参数提高发射功率,以保证接收设备能够正确接收信号。 Increase the transmission power of the transmission device according to the power adjustment parameter to ensure that the receiving device can receive signals correctly. 或者,当发射功率过大时,虽然该发射功率未超过最大发射功率,但出于减少设备功耗,提高电池续航能力的目的,接收设备会要求发送设备降低发射功率。 Alternatively, when the transmission power is too large, although the transmitting power does not exceed the maximum transmit power, but the equipment for reducing the power consumption and improve battery life of the object, the receiving apparatus can reduce the transmission power requirements of the transmission device. 发送设备根据该功率调整参数,在保证接收功率不低于接收设备能够正确接收信号的最低接收功率的前提下,降低发射功率。 The premise of the transmission device to the power adjustment parameter, the received power is not less than the minimum guaranteed reception power of a signal receiving apparatus capable of receiving correct, reduce transmit power.

[0125] 进一步优选的,当发送设备选择好一个发射功率并根据该发射功率与接收设备开始进行通信后,仍旧会根据通信资源的条件,更换通信资源。 [0125] Further preferably, a good choice when the transmitting apparatus starts the transmission power and the transmitting power according to communication with the receiving apparatus, the communication resource will still be in accordance with conditions, the replacement of the communication resources.

[0126] 具体的,发送设备接收接收设备发送的所有通信资源的干扰敏感程度信息以及干扰过载程度信息的bitmap列表,如果根据新bitmap列表选择出来的通信资源的抗干扰能力强于目前所使用的通信资源时,发送设备选择所述新的通信资源作为与接收设备进行通信所使用的通信资源,根据新通信资源的条件重新计算最大发射功率以及最小发射功率并确定一个新的发射功率。 [0126] Specifically, the receiver receives all communication resources sent by the interference sensitivity information transmitting apparatus and interference overload bitmap listing extent carrier information, if a strong interference suppression ability of the new bitmap list selected communication resources in use today when communication resources, the transmitting device selects a new communication resource as a receiving device for a communication resource used for communication, the maximum transmit power and recalculates the minimum transmit power based on the new communication resource conditions and determine a new transmit power.

[0127] 需要说明的是,上述所述发送设备与所述接收设备同质,都为UE。 [0127] Incidentally, the above-described transmitting device and the receiving device homogeneity are UE. 在本实施例中, 将发射信号的UE作为发送设备、将接收信号的UE作为接收设备,仅为便于表述。 In the present embodiment, the UE UE device transmits the transmission signal as the received signal as a reception apparatus, ease of presentation only. 实际D2D 应用中,UE之间进行交互式通信,每一部UE都既为发送设备又为接收设备。 D2D practical applications, interactive communication, each unit are both UE device to transmit and receive between the UE device.

[0128] 此外,还存在另一种应用场景:发送设备作为主设备接收接入设备下发的相关信息,接收设备由于不能与接入设备进行通信而作为从设备不接收接入设备下发的相关信息。 [0128] In addition, there is another application scenario: the access device receiving the transmission device information as issued by the master device, since the receiving apparatus can not communicate with the access device is sent from the device as the access device does not receive Related Information. 由于接收设备在D2D通信中不需接收接入设备的相关信息,所以作为主设备的发送设备不将所述接入设备下发的相关信息发送给接收设备。 Since the receiving apparatus without receiving related information access device in the D2D communication, it does not send a transmission apparatus main device delivered by the access device-related information to a receiving device. 此种应用场景下,执行方案与实施例二相同,此处不再赘述。 In this scenario, the program performs the same as the second embodiment will not be repeated here.

[0129] 本发明实施例提供的设备发射功率控制的方法,能够根据发送设备到接入设备的路损与接入设备能够接受的最大干扰信号功率以及发送设备到接收设备的路损与接收设备的最小接收功率分别计算出最大发射功率和最小发射功率,然后根据最大发射功率和最小发射功率选择通信所使用的发射功率。 [0129] The method of transmitting power control apparatus according to an embodiment of the present invention, the receiving apparatus according to the maximum interference signal power transmitting device and a transmission device path loss to the access device and the access device capable of accepting path loss and reception apparatus the minimum received power, respectively, to calculate the maximum transmission power and minimum transmission power, and then select the transmit power used for communication in accordance with the maximum transmission power and minimum transmission power. 避免了发射功率过大对接入设备或其他用户造成干扰,以及发射功率过小无法正确发送信号的情况。 To avoid the transmission power caused by too much interference to other users or access device, and launches power is too small can not send the right signal.

[0130] 此外本发明实施例提供的设备发射功率控制的方法,还能够在发送设备与接收设备进行通信的过程中,调整发射功率的大小,以保证以最小的发射功率正确发送信号。 [0130] Further transmit power control method according to an embodiment of the present invention, it is possible in the process of transmitting and receiving devices to communicate, the transmission power resized, in order to ensure a minimum transmission power to correct the transmission signal. 或者,在发送设备与接收设备进行通信的过程中,选择抗干扰能力更强的通信资源,以保证发送设备与接收设备能够使用通信条件最好的通信资源进行通信。 Alternatively, the process of sending and receiving devices to communicate, select stronger anti-interference capability of the communication resources to ensure the transmission and receiving devices to use the best communication conditions of the communication resources for communication.

[0131] 本发明实施例的方法可以由处理器(包括CPU在内)或ASIC等执行,对此本发明实施例不作限制。 The method of embodiment [0131] The present invention may be performed by a processor and the like (including a CPU included) or ASIC, this embodiment of the present invention is not limited.

[0136] 与实施例三不同的是,本实施例中,发送设备无需与接入设备进行通信,而是由第三设备接收接入设备发送的所述通信资源的干扰敏感程度信息以及干扰过载程度信息,并将该信息发送给发送设备,以保证发送设备能够获取到选择通信资源的必要信息。 [0136] and three different embodiments is communicating embodiment, the transmitting device need not access device of the present embodiment, but by the interference of the communication resources of the third receiving device transmitting sensitive information access device and interference overload degree information, and transmits the information to the transmitting apparatus, in order to ensure that the transmission device can obtain the necessary information for selecting a communication resource. 所述第三设备为独立于所述发送设备和接收设备的第三个D2D设备。 The third device is independent of the transmitting and receiving devices of the third D2D device. 当发送设备与接收设备都无法与接入设备进行通信时,由所述第三设备将接入设备发送的所述通信资源的干扰敏感程度信息以及干扰过载程度信息发送给发送设备。 When the transmitting and receiving devices can not communicate with the access apparatus, the interference of the communication resource by the third device to access sensitive information sent by the device and by transmitting interference degree information to the transmission device overload.

[0137] 本实施例中,第三设备作为主设备,用于传递接入设备信息,不参与D2D通信过程。 [0137] In this embodiment, the third device as a master device, the access device for transmitting information, does not participate in D2D communication procedure. 所述发送设备与接收设备作为从设备,从第三设备获取接入设备信息,不直接接收接入设备发送的信息。 The transmitting and receiving devices as a slave device, the third device obtaining access from the device information, the access information receiving apparatus is not directly transmitted. 所述主从设备为从是否直接从接入设备处获取接入设备信息的角度定义,与所述发射接收设备的定义无关,本实施例中主设备为所述第三设备,从设备为所述发送设备和所述接收设备。 From the master device is defined from the access device whether to obtain information directly from the access device the angle, independent of its definition the transmitting and receiving apparatus, according to the present embodiment, the third device is a master device, the slave device is said transmitting apparatus and the receiving apparatus.

[0138] 本实施例中D2D设备自主选择通信资源,选择通信资源的依据为接入设备发送的干扰敏感程度信息以及干扰过载程度信息。 [0138] Examples D2D device according to choose a communication resource, the present embodiment selects a communication resource for the access interference sensitivity information transmitted over the degree of interference and information overload. 接入设备将其管辖内所有用户的通信资源的干扰敏感信息以及干扰过载信息以bitmap列表的形式下发给第三设备。 The access device interfering communication resources for all users within its jurisdiction sensitive information and interference overload information sent under the form of a third device list bitmap. 例如,把所有通信资源的干扰敏感程度信息和干扰过载程度信息,以bitmap的形式下发给第三设备,bitmap列表中的第0位赋值第一个通信资源的干扰敏感信息,第1位赋值第二个通信资源的干扰敏感信息,以此类推。 For example, the interfering communication resources all sensitive information and the interference information over the degree of overload, under the form of a bitmap sent to a third device, the first bitmap list 0 first communication resource assignment interference sensitive information, assigning 1 bit the second interference communication resource sensitive information, and so on. 每一bit位有0和1两种状态,0状态代表干扰敏感1状态代表干扰不敏感,或者1状态代表干扰敏感0状态代表干扰不敏感。 Each bit position has two states 0 and 1, a 0 state represents a state representative of the interference sensitive insensitive to interference, the interference state represents 1 or 0 state represents a sensitive insensitive to interference. 将所有通信资源的干扰敏感信息以bitmap列表的形式发送给第三设备。 The interference of all communication resources sensitive information to a third device in the form of bitmap list. 干扰过载信息可以以相同的形式下发给第三设备, 此处不再赘述。 Interference overload information can be sent to a third device in the same form, will not be repeated here.

[0139] 步骤402至409与实施例三中步骤302至309对应相同,只是获取并向发送设备发送接入设备能够接受的最大干扰信号功率、接收接入设备发送的参考信号序列、根据该参考信号序列计算并向发送设备发送发送设备到接入设备的路损这三个步骤的执行主体替换为第三设备,此处不再赘述。 [0139] Step 402 to 409 in three steps as in Example 302 to 309 correspond to only obtain the maximum transmission power of the interference signal transmitting apparatus can accept an access device, receives a reference signal sequence sent by the access device, according to the reference signal sequence to the computing device to the transmission device transmits transmission path loss of the access device performs three main steps with a third device, it is not repeated here.

[0140] 本实施例中,发送设备无需与接入设备进行通信,所以与步骤401相同,所述最大干扰信号功率也由第三设备(主设备)从接入设备获取然后发送给发送设备(从设备)。 [0140] In this embodiment, the transmitting device need not communicate with the access device, it is the same as step 401, the maximum power of the interference signal to be acquired is then transmitted from the transmitting device by a third device, the access device (master) ( from the device).

[0141] 需要说明的是,最大发射功率值与接入设备能够接受的最大干扰信号功率值相关,而接入设备能够接受的最大干扰信号功率值因通信资源质量的不同而不同;同样,最小发射功率值与发送设备到接收设备的路损值相关,而发送设备到接收设备的路损值因通信资源质量的不同而不同。 [0141] Incidentally, the maximum transmission power value and the access device capable of accepting a maximum interference signal power values ​​associated, the access device can accept a maximum interference signal power value of the communication quality due to the different resources are different; Similarly, the minimum transmission power value and the transmission device to the reception device path loss correlation value, the device transmits to the receiving device path loss due to communication quality different resources are different. 由此会出现最大发射功率小于最小发射功率的情况。 Whereby the maximum transmit power is less than the minimum transmission power appears. 出现此情况时,发送设备所选择的通信资源无法利用,需要重新选择通信资源,并根据新的通信资源计算最大最小发射功率。 When this occurs, the communication resource for transmitting the selected device can not be used, need to select a communication resource, and calculates the maximum and minimum transmission power according to the new communication resource.

[0143] 具体的,当接收设备接收信号的接收功率小于其能够正确接收该信号的最小功率时,接收设备会在发送的信标帧中携带功率调整参数给发送设备,要求发送设备提高发射功率。 [0143] Specifically, when receiving the power receiving device receiving signal is less than that capable of receiving the minimum power of the signal properly, the receiving apparatus carries power adjustment parameter to the transmission device in the beacon frame transmitted, it requires transmission apparatus to improve the transmission power . 发送设备根据该功率调整参数提高发射功率,以保证接收设备能够正确接收信号。 Increase the transmission power of the transmission device according to the power adjustment parameter to ensure that the receiving device can receive signals correctly. 或者,当发射功率过大时,虽然该发射功率未超过最大发射功率,但出于减少设备功耗,提高电池续航能力的目的,接收设备会要求发送设备降低发射功率。 Alternatively, when the transmission power is too large, although the transmitting power does not exceed the maximum transmit power, but the equipment for reducing the power consumption and improve battery life of the object, the receiving apparatus can reduce the transmission power requirements of the transmission device. 发送设备根据该功率调整参数,在保证接收功率不低于接收设备能够正确接收信号的最低接收功率的前提下,降低发射功率。 The premise of the transmission device to the power adjustment parameter, the received power is not less than the minimum guaranteed reception power of a signal receiving apparatus capable of receiving correct, reduce transmit power.

[0144] 进一步优选的,当发送设备选择好一个发射功率并根据该发射功率与接收设备开始进行通信后,仍旧会根据通信资源的条件,更换通信资源。 [0144] Further preferably, a good choice when the transmitting apparatus starts the transmission power and the transmitting power according to communication with the receiving apparatus, the communication resource will still be in accordance with conditions, the replacement of the communication resources.
