[0074] 具体的,如果是由基站触发的建网流程,则该D2D分布式网络数据传输请求是基站通过广播信令或无线资源控制(Rad1 Resource Control,RCC)发送给UE的;如果是由UE自身触发的建网流程,则该D2D分布式网络数据传输请求是从自身的应用层获取的,具体方式此处不做限定。 [0074] Specifically, if the base station is triggered by the network construction process, the distributed network D2D data transmission request is sent to the UE by the base station broadcast signaling or radio resource control (Rad1 Resource Control, RCC); if the UE networking process itself triggered the distributed network D2D data transmission request is obtained from its own application layer, the specific embodiment is not limited here.

[0077] 该时频域资源可以由基站发送给UE的时频域资源,也可以是由UE所在的服务小区的服务基站预配置或者UE自配置的时频域,具体此处不做限定。 [0077] The time-frequency domain resources may be sent by the base station to the UE frequency domain resource, a service may be a cell of a serving base station where the UE preconfigured or self-configuration of the UE in the frequency domain, it is not particularly defined here.

[0078] 需要说明的是,如果是基站向UE发送D2D分布式网络的数据传输请求和向UE发送进行信道测量的时频域资源,那这两者可以是通过同一个信令一起发送给UE的,也可以通过不同的信令发送给UE,具体此处不做限定。 [0078] Incidentally, if the base station transmits a data transmission request to the UE D2D distributed network and sending to the UE measuring channel frequency domain resource, and that the two may be transmitted together through the same signaling to the UE and may be sent to the UE through different signaling, is not particularly defined here.

[0079] 203,UE在获取D2D分布式网络数据传输请求后,对该时频域资源所在的其中一个信道进行测量以确定该信道是否空闲; [0079] 203, UE after obtaining a distributed network D2D data transmission request, the time-frequency domain resource is a channel which is measured to determine whether the channel is idle;

[0080] UE获取的时频域资源的频域范围划分为多个信道,UE在获取D2D分布式网络数据传输请求后,对该时频域资源所在的信道进行测量,以找到空闲的信道,具体测量时,是对其中的一个信道进行测量以确定该信道是否空闲。 After the [0080] frequency domain resource of the frequency domain the UE acquired into a plurality of channels, UE acquiring D2D distributed network data transfer request, the time-frequency channel domain resource location is measured, to find a free channel, specifically measurements, is a channel which is measured to determine whether the channel is idle.

[0082] UE对该信道进行测量后,当确定该信道为空闲信道时,UE在该信道上建立D2D连接。 [0082] After the UE measures the channel, when it is determined that the channel is a free channel, the UE D2D connection establishment channel.

[0083] 本发明实施例中,UE获取到D2D分布式网络建网指令后,获取进行信道测量的时频域资源,再对该时频域资源所在的信道进行测量以确定信道是否空闲,若信道空闲,则通过该信道建立D2D连接。 After [0083] embodiment of the present invention, the UE acquires D2D distributed network networking instruction, acquiring channel measurement frequency domain resource, channel domain resources located measured to determine whether the channel is idle again when the frequency, if the channel is idle, the D2D connection is established through the channel. 本发明提出了基于D2D分布式网络下的资源分配流程,能够实现基于D2D分布式网络的D2D多跳数据传输场景下的资源分配。 The present invention proposes a resource allocation process in the distributed network D2D possible based on the distributed network D2D D2D resource allocation in multi-hop data transmission scenario.

[0085] 具体的,UE进行测量的频域范围可以是由基站通过广播信令或无线资源控制(Rad1 Resource Control,RCC)信令直接发送给UE的某些子信道,也可以是由基站给出用作D2D通信某个大的频域范围,由UE根据自身的需要对该频域资源进行划分形成多个子信道。 [0085] Specifically, UE perform frequency domain measurements may be broadcast by a base station or radio resource control signaling (Rad1 Resource Control, RCC) signaling is sent directly to the UE through some subchannels may be given by the base station the D2D communication as large a frequency domain, divide the frequency domain by a UE according to their resource needs are formed a plurality of subchannels.

[0086] 具体的,UE进行测量的时域范围可以是由基站通过广播信令或RCC信令发送的测量专用子帧,还可以是基站发送给UE —个配置参数,由UE根据配置参数获知通过UE正常数据发送和接收的静默期进行信道测量,静默期即正常数据发送的空闲时段,例如:多播/组播单频网络(Multimedia Broadcast multicast service Single Frequency Network,MBSFN)子帧或时分双工(Time Divis1n Duplexing,TDD)特殊子帧中的保护间隔(Guardper1d,GP)。 [0086] Specifically, the UE performs time domain measurements may be measured by a base station through a subframe dedicated signaling or broadcast signaling RCC transmitted, the base station may also be transmitted to the UE - configuration parameters, known by the UE according to the configuration parameters channel measurements transmitted and a silent period received by the UE normal data, the silent period i.e. normal data idle period sent, for example: a multicast / multicast single frequency network (Multimedia broadcast multicast service single frequency network, MBSFN) subframe or time division bis Engineering (Time Divis1n Duplexing, TDD) guard interval in special subframe (Guardper1d, GP).

[0087] 在实际应用中,对信道的空闲检测的方式可以是以信道上的信号功率总和进行判断,下面详细进行说明: [0087] In practical applications, the channel idle mode detection signal may be a sum of the channel power is determined, will be described in detail below:

[0088] 结合图3,本发明实施例提供了一种D2D通信方法,包括: [0088] in conjunction with FIG. 3, the present invention provides a D2D communication method, comprising:

[0089] 301、UE获取D2D分布式网络数据传输请求; [0089] 301, UE acquires a distributed network D2D data transmission request;

[0090] 在D2D分布式网络建网过程中,需要由基站或UE自身触发建网流程,UE获取到进行D2D分布式网络数据传输请求,如此UE才能开始建立D2D分布式网络的D2D连接。 D2D [0090] In a distributed network D2D networking process itself needs to be triggered by the base station or a UE network building process, the UE acquires a distributed network of D2D data transmission request, so D2D UE can not start the distributed network connection.

[0091] 具体的,如果是由基站触发的建网流程,则该D2D分布式网络数据传输请求是基站通过广播信令或无线资源控制(Rad1 Resource Control,RCC)发送给UE的;如果是由UE自身触发的建网流程,则该D2D分布式网络数据传输请求是从自身的应用层获取的,具体方式此处不做限定。 [0091] Specifically, if the base station is triggered by the network construction process, the distributed network D2D data transmission request is sent to the UE by the base station broadcast signaling or radio resource control (Rad1 Resource Control, RCC); if the UE networking process itself triggered the distributed network D2D data transmission request is obtained from its own application layer, the specific embodiment is not limited here.

[0092] 302、UE获取进行信道测量的时频域资源; When the [0092] 302, UE channel measurement acquisition frequency domain resource;

[0093] UE在建立基于分布式网络的D2D连接时,需要进行信道测量以找到空闲的信道,在进行信道测量时,UE需要先获取进行信道测量的时频域资源。 When the [0093] UE when creating the distributed network-based D2D connection, channel measurement is required to find a free channel, the channel measurement is performed, the UE needs to acquire channel measurement frequency domain resource.

[0094] 该时频域资源可以由基站发送给UE的时频域资源,也可以是由UE所在的服务小区的服务基站预配置或者UE自配置的时频域,具体此处不做限定。 [0094] The time-frequency domain resources may be sent by the base station to the UE frequency domain resource, a service may be a cell of a serving base station where the UE preconfigured or self-configuration of the UE in the frequency domain, it is not particularly defined here.

[0095] 需要说明的是,如果是基站向UE发送D2D分布式网络的数据传输请求和向UE发送进行信道测量的时频域资源,那这两者可以是通过同一个信令一起发送给UE的,也可以通过不同的信令发送给UE,具体此处不做限定。 [0095] Incidentally, if the base station transmits a data transmission request to the UE D2D distributed network and sending to the UE measuring channel frequency domain resource, and that the two may be transmitted together through the same signaling to the UE and may be sent to the UE through different signaling, is not particularly defined here.

[0096] 303、UE计算该时频域资源所在的其中一个信道上不同信号源的信号的功率总和; [0096] 303, UE calculates the sum of the power of the signal time-frequency domain resource is one of the channels of different sources;

[0097] UE获取的时频域资源中的频域范围划分为多个子信道,UE在获取D2D分布式网络数据传输请求后,对该时频域资源所在的信道进行测量,以找到空闲的信道,具体测量时,是对其中的一个信道进行测量以确定该信道是否空闲。 [0097] frequency domain frequency domain resources in the UE acquired into a plurality of sub-channels, distributed D2D UE after acquiring network data transfer request, the time-frequency domain resource is a channel is measured, to find a free channel when specific measurement, which is a channel is measured to determine whether the channel is idle.

[0098] 具体的测量方法为:UE计算该信道上不同信号源的信号的功率总和Σ Rx,特别地,上述检测信道如果和当前UE所处工作频率不在同一频段时,可由基站配置或UE自发配置measurement gap,在measurement gap时间内发起异频测量。 [0098] A specific measurement method: the UE calculates the sum of power of the signal on the channel Σ Rx different sources, in particular, the detection and the current channel if the UE is not located in the same operating frequency band, the base station may configure the UE spontaneously or configured measurement gap, to initiate inter-frequency measurements in the time measurement gap.

[0099] 304、UE判断功率总和是否小于预设阈值以确定该信道为空闲信道; [0099] 304, UE determines power sum is smaller than a preset threshold value to determine if the channel is idle channel;

[0100] 若信道上不同信号源的信号的功率总和小于预设阈值,则UE确定信道为空闲信道,若大于或等于预设阈值,则UE确定该信道为非空闲信道。 [0100] When the sum of the power of the signal channel different sources less than a preset threshold, the UE determines the channel as a free channel, if greater than or equal to a preset threshold, the UE determines that the channel is non-free channel. 具体的,预设阈值可以是由基站通过测量参数下发的,也可以在UE的预配置参数中配置的。 Specifically, the predetermined threshold may be issued by the base station through the measurement parameters, may be arranged in a pre-configured parameter of the UE.

[0101] 在具体的实施中,为了避免短时间的信道空闲占用信道带来的干扰,在预置的时间内,UE对该信道进行多次测量,测量的次数为预设阈值M,若M次测量的结果均为空闲时,UE才认为该信道真正的空闲,需要说明的是,M次测量可以为非连续性测量,也可以为连续性的测量。 [0101] In a particular embodiment, in order to avoid interference of the channel is idle for a short time occupies the channel brought within the preset time, the UE channel the multiple measurements, the measurement number is a preset threshold value M, if M results of measurements are idle, the UE only considers the true channel is idle, Incidentally, M may be non-continuous measurements measured may be a continuous measurement.

[0102] 305、若信道空闲,则UE在信道建立D2D连接; [0102] 305, if the channel is idle, the UE D2D connection establishment channel;

[0103] UE对该信道进行测量后,当确定该信道为空闲信道时,UE在该信道上建立D2D连接。 [0103] After the UE measures the channel, when it is determined that the channel is a free channel, the UE D2D connection establishment channel.

[0104] 306、若信道非空闲,则UE跳转到下一个信道进行测量或在预设的测量避让时间之后重新在信道进行测量。 [0104] 306, if the channel is not idle, the UE jumps to the next channel measurements or channel re-measured in the preset measuring time after the escape.

[0105] 若UE检测到信道非空闲时,UE跳转到该时频域资源的下一个子信道进行测量,或者在预设的测量避让时间之后重新在该信道上进行测量。 [0105] If the channel is detected when the non-idle UE, UE go to the next subchannel of the frequency domain resource is measured or preset measurement on the channel re-measured after the escape time.

[0106] 在另一种具体的实施中,当UE在该信道上检测到有规律的标志性信号时,表示其他的UE已经预占用了该信道,则UE可以确定此信道为非空闲信道。 [0106] In another specific embodiment, when the UE on the channel detecting the flag of a regular signal, showing another UE has been pre-occupied by the channel, the UE may determine the channel is non-free channel.

[0107] 在本发明实施例中,UE可以通过计算信道上的不同信号的功率总和是否小于预设阈值来判断测量信道是否空闲,或通过检测信道是否有规律的标志性信号来判断信道是否空闲,从而提高了方案的可实现性。 [0107] In an embodiment of the present invention, the UE may be determined measure the channel is idle by the power sum of the different signals calculated channel is less than a predetermined threshold value, or whether regularly by detecting the channel symbol signals to determine whether a channel is idle , thereby improving the realization of the program.

[0108] 进一步,在一种具体的实施中,有多个UE同时在一块时频域资源上进行信道的测量,为了避免多个UE间发生测量冲突,本发明实施例采用了预占用信道和随机接入测量时间机制。 [0108] Further, in a particular embodiment, the simultaneous measurement of a plurality of UE's in a time channel on a frequency domain resource, in order to avoid a conflict between a plurality of UE measurements, embodiments of the present invention employs a pre-assigned channel and measuring the time the random access mechanism. 下面进行详细说明: Described in detail below:

[0109] 结合图4,本发明实施例提供了一种D2D通信方法,包括: [0109] in conjunction with FIG. 4, embodiments of the present invention provides a D2D communication method, comprising:

[0110] 401、UE获取D2D分布式网络数据传输请求; [0110] 401, UE acquires a distributed network D2D data transmission request;

[0111] 在D2D分布式网络建网过程中,需要由基站或UE自身触发建网流程,UE获取到进行D2D分布式网络数据传输请求,如此UE才能开始建立D2D分布式网络的D2D连接。 D2D [0111] In a distributed network D2D networking process itself needs to be triggered by the base station or a UE network building process, the UE acquires a distributed network of D2D data transmission request, so D2D UE can not start the distributed network connection.

[0112] 402、UE获取进行信道测量的时频域资源; When the [0112] 402, UE channel measurement acquisition frequency domain resource;

[0113] 当UE需要建立基于分布式网络的D2D连接时,需要进行信道测量以找到空闲的信道,在进行信道测量时,UE需要先获取进行信道测量的时频域资源。 When [0113] When the UE needs to establish a distributed network-based D2D connection, channel measurement is required to find a free channel, the channel measurement is performed, the UE needs to acquire channel measurement frequency domain resource.

[0114] 该时频域资源可以由基站发送给UE的时频域资源,也可以是由UE所在的服务小区的服务基站预配置或者UE自配置的时频域,具体此处不做限定。 [0114] The time-frequency domain resources may be sent by the base station to the UE frequency domain resource, a service may be a cell of a serving base station where the UE preconfigured or self-configuration of the UE in the frequency domain, it is not particularly defined here.

[0115] 该进行信道测量的时频域资源包括时域范围和频域范围,因此,UE实际是获取进行信道测量的时域范围和进行测量的频域范围。 [0115] When the measured channel frequency domain and time domain resources include frequency domain, therefore, the UE actually measured the acquisition channel time domain and the frequency domain measurements.

[0116] 具体的,UE进行测量的频域范围可以是由基站通过广播信令或无线资源控制(Rad1 Resource Control,RCC)信令直接发送给UE的某些子信道,也可以是由基站给出用作D2D通信某个大的频域范围,由UE根据自身的需要对该频域资源进行划分形成多个子信道。 [0116] Specifically, UE perform frequency domain measurements may be broadcast by a base station or radio resource control signaling (Rad1 Resource Control, RCC) signaling is sent directly to the UE through some subchannels may be given by the base station the D2D communication as large a frequency domain, divide the frequency domain by a UE according to their resource needs are formed a plurality of subchannels.

[0117] 具体的,UE进行测量的时域范围可以是由基站通过广播信令或RCC信令发送的测量专用子帧,还可以是基站发送给UE —个配置参数,由UE根据配置参数获知通过某正常数据发送和接收的静默期进行信道测量,静默期即正常数据发送的空闲时段,例如:多播/组播单频网络(Multimedia Broadcast multicast service Single Frequency Network,MBSFN)子帧或时分双工(Time Divis1n Duplexing,TDD)特殊子帧中的保护间隔(Guardper1d,GP)。 [0117] Specifically, the UE performs time domain measurements may be measured by a base station through a subframe dedicated signaling or broadcast signaling RCC transmitted, the base station may also be transmitted to the UE - configuration parameters, known by the UE according to the configuration parameters channel measurements transmitted and a silent period received by a normal data, the silent period i.e. normal data idle period sent, for example: a multicast / multicast single frequency network (Multimedia broadcast multicast service single frequency network, MBSFN) subframe or time division bis Engineering (Time Divis1n Duplexing, TDD) guard interval in special subframe (Guardper1d, GP).

[0118] 403、UE获取测量随机量B和测量时长T ; [0118] 403, UE acquires the measurement time period T B, and the amount of random measurement;

[0119] 当UE在进行信道测量时,为了避免D2D分布式网络节点在同一时刻进行信道测量而引起的测量冲突,UE获取测量随机量B,用来确定UE在发起信道测量的随机时间量,同时UE获取测量时长T,T为UE进行信道测量的持续测量时间。 [0119] When the UE performing channel measurement, measurement conflict in order to avoid D2D distributed network node channel measurement at the same time caused, UE acquires the measurement random quantity B, for determining a random amount of time to initiate channel measurements UE, while the UE acquires the measurement period T, T for measuring time duration of the channel measurement UE.

[0120] 需要说明的是,测量随机量B可以是由基站通过专用信令发送给UE的,也可以是UE自身确定的,还可以是由基站配置了一个随机量B池,UE从该随机量B池中随机选择一个作为UE进行测量的随机量B。 [0120] Incidentally, the measurement may be a random amount B to the UE via dedicated signaling by the base station, may be determined by the UE itself, the base station may also be configured by a random amount of pool B, UE from the random an amount of a pool of randomly selected B as random measurement UE B.

[0121] 测量时长T可以是基站通过广播信令发送给UE的,也可以是由协议规定的一个固定常量,还可以是UE自身预配置的,具体此处不做限定。 [0121] measurement time period T may be a base station transmits signaling to the UE through a broadcast, or may be a fixed constant defined by the protocol, may also be pre-configured the UE itself, is not particularly defined here.

[0122] 需要说明的是,测量随机量B、测量时长T和测量时频域资源如果都是由基站下发的,则可以是在一个信令中作为信道测量的参数进行下发,也可以通过不同的信令下发,具体方式此处不做限定。 [0122] Incidentally, measurement of the random quantity B, and the measurement time period T and the measurement field frequency resource if is issued by the base station, may be issued as a parameter channel measurements in a signaling may be issued by different signaling specific embodiment is not limited here.

[0123] 404,UE根据测量随机量B和测量时长T确定UE在该时频域资源上的测量起始时间; [0123] 404, the UE randomly measured amount B and the UE according to the measurement period T is determined on the frequency measurement start time in the time domain resource;

[0124] 在UE获取测量随机量B和测量时长T后,根据测量随机量B和测量时长T确定UE在该时频域资源上的测量起始时间,以使得各UE在该时频域资源上的测量起始时间不相同,能够错开进行测量的时间。 After [0124] acquisition period T measured random amount B and the measured UE, according to the measurement random amount B and the measurement period T is determined UE-frequency measurement start time domain resource at this time, so that each UE frequency domain resource in the time measurement starting time is not the same, a time measurement can be shifted.

[0125] 405,UE从测量起始时间开始,在测量时长T内对该时频域所在的其中一个信道进行测量以确定该信道是否空闲; [0125] 405, UE starts the measurement start time, when measuring the frequency domain where the time period T within a channel which is measured to determine whether the channel is idle;

[0126] UE在确定了测量起始时间后,从各自的测量起始时间开始,在测量时长T内对该时频域所在的其中一个信道进行测量以确定该信道是否空闲。 [0126] UE after determining the measurement start time, starting from the start time of the respective measurement, in the measurement of the frequency domain is located within a channel in which the period T measured to determine whether the channel is idle.

[0133] 在具体的实施例中,UE根据测量随机量B和测量时长T确定UE在该时频域资源上的测量起始时间的具体方式可以包括以下两种: [0133] In a particular embodiment, UE determines that the UE according to the measurement period T DETAILED frequency measurement start time domain resources may include the following two randomly when the measured amount B and:

[0134] 一、以B和T的乘积在所述时频域资源上相应的时间点作为测量起始时间。 [0134] First, the product of B and T to respective time-frequency domain resource as the measurement start time.

[0135] UE将时频域资源给出的时域资源起始点之后NI个时间单位作为UE的测量起始时间,NI为测量随机量B与测量时长T的乘积,满足其他UE的测量起始时间是T的随机倍数,不同UE的测量发起时间完全错开,使得该UE的测量起始时间大于或等于上一个UE的测量结束时间,不同UE的信道测量时间不会重叠。 After the [0135] UE starting a time domain resource time-frequency domain resource NI given time unit as the measurement start time of the UE, a random NI measurement measured amount B and the product of duration T, the UE starting to meet the measurement of other T is a random multiple of the time, the UE different measurement initiation time offset completely, so that the UE measurement start time equal to or greater than a measurement end time of the UE, UE measurement channels of different times do not overlap.

[0136] 如图5所示,信道测量的频域范围包括3个子信道:信道1、信道2、信道3,假设:信道测量的时频域资源的时域资源起始点为tl,UEl的B为BI = 0,UE2的B为B2 = 1,UEl和UE2的测量时间都为固定的时间T = lms,则UEl的测量起始时间为tl+Bl*T = tl, UEl的测量结束时间为tl+lms,UE2的测量起始时间为tl+B2*T = tl+lms,UE2的测量结束时间为tl+2ms。 [0136] As shown, the frequency domain channel measurement comprises 53 sub-channels: channel 1, channel 2, channel 3, it is assumed: The time-frequency domain resource domain resources starting channel measurement is tl, UEl and B as BI = 0, UE2 and B is B2 = 1, UEl and UE2 have the measurement time is a fixed time T = lms, then the measurement start time is UEL tl + Bl * T = tl, the end of the measurement time UEL tl + lms, UE2 measurement start time tl + B2 * T = tl + lms, UE2 measurement end time tl + 2ms. 所以UEl和UE2进行测量的时间不会重叠。 Therefore UEl and UE2 for measuring time do not overlap.

[0137] 如图5所示,UEl在信道2上测量后,确认信道2为空闲信道,若此时还没有到UE建立D2D连接的时间点,例如UE必须在子帧的边界才能发起D2D连接,则此时UE不会马上发起D2D连接。 [0137] 5, UEL 2 after measurement channel, an acknowledgment channel 2 channel is idle, if this point, had not established to the UE D2D connection time, e.g. UE must initiate a D2D connection to the sub-frame boundaries is UE at this time will not immediately initiate a D2D connection. 此时UE2发起信道测量,任然认为信道2为空闲信道,则也会在子帧边界发起D2D连接,从而仍然会造成UEl和UE2使用相同资源的冲突。 In this case UE2 initiating channel measurements, any course that channel 2 channel is idle, the D2D connection will initiate the subframe boundary, which still cause conflicts UEl and UE2 use the same resource.

[0138] 因此,为了避免上述冲突,测量UEl需在发现信道空闲后,发出预占用信道,防止其他UE占用信道。 [0138] Accordingly, in order to avoid such conflicts, measured after UEl required channel is found idle, issued preassigned channel, to prevent other UE occupies the channel. 则UE先预占用该信道,以防止其他UE占用该信道。 Pre-assigned to the UE of the channel to prevent the channels occupied by another UE. 若是通过发射无功率信号预占用信道,则信道预占用如图6所示,若是发射有规律标识性信号,则信道预占用如图7所示,该有规律标识性信号是周期性的特性信号。 By transmitting a power signal if no pre-assigned channel, the channel reservation occupies shown in FIG. 6, if the regular emission of the identification signal, the channel reservation occupies shown in Figure 7, the regular signal is an identification signal characteristic of a periodic .

[0139] 二、以测量随机量B在所述时频域资源上相应的时间点作为测量起始时间。 [0139] Second, the amount of random measurement point B on the corresponding time-frequency domain resources as a measurement start time at said time.

[0140] UE将时频域资源给出的时域资源起始点之后N2个时间单位作为UE的测量起始时间,N2为测量随机量B,该随机量B为随机数,因此使用此种方式不同UE的测量时间并未完全错开,不同UE的信道测量时间有可能重叠。 After the [0140] UE starting the time domain resources given time-frequency domain resource of N2 time units of measurement starting time of the UE, a random measured amount B is N2, the amount of B is the random nonce, and therefore the use of such way UE different measurement time is not completely offset, a different channel measurement time UE is likely to overlap.

[0141] 如图8所示,信道测量的频域范围包括3个子信道:信道1、信道2、信道3,假设:信道测量的时频域资源的时域资源起始点为tl,UEl的B为BI = 0,UE2的B为B2 = 0.5,UEl和UE2的测量时间都为固定的时间T = 1ms,则UEl的测量起始时间为tl+Bl = tl,UEl的测量结束时间为tl+lms,UE2的测量起始时间为tl+B2 = tl+0.5ms,UE2的测量结束时间为tl+1.5ms,则在UEl还没测量结束时,UE2已经开始测量,所以,UEl和UE2的测量时间有重叠。 [0141] As shown in FIG. 8, frequency domain channel measurement comprises three sub-: channel 1, channel 2, channel 3, it is assumed: The time-frequency domain resource domain resources starting channel measurement is tl, UEl and B as BI = 0, UE2 and B is B2 = 0.5, UEl and UE2 have a fixed measurement time of the time T = 1ms, for the measurement starting time is UEL tl + Bl = tl, UEl measurement end time tl + LMS, UE2 measurement starting time is tl + B2 = tl + 0.5ms, UE2 measurement end time tl + 1.5ms, not at the time of measurement end UEL, UE2 measurement has begun, so, measuring and UE2 UEL time overlap.

[0142] 如图8所示,由于不同UE的测量时间并未要求完全错开,因此,不同UE的信道测量时间有可能重叠,可能导致不同UE在检测同一信道并同时得到信道空闲的冲突,因此,为了避免上述冲突,测量UEl需在发现信道空闲后,马上在下一个测量时间起始位置发出预占用信道。 [0142] As shown, since the measurement time different UE did not require completely shifted, therefore, the channel measurement time different UE are likely to overlap, may result in 8 different UE and also give the channel is idle conflict detection same channel, thus in order to avoid such conflicts, measured after UEl required channel is found idle, immediately next time measurement start position sent preassigned channel.

[0143] 若是通过发射无功率信号预占用信道,则信道预占用如图9所示,若是发射有规律标识性信号,则信道预占用如图10所示,该有规律标识性信号是周期性的特性信号。 [0143] If no power signal by transmitting a pre-occupation of the channel, the channel reservation occupies shown in FIG. 9, if the regular emission of the identification signal, the channel reservation occupies 10, identification of the regular signal is periodic the characteristics of the signal.

[0144] 进一步,作为另一个实施例,UE在建立D2D分布式网络连接前,还可以获取D2D分布式网络连接的最大中继数,以限制UE在信道上建立D2D连接时所使用的中继数小于或等于最大中继数。 [0144] Further, as another example, the UE prior to the establishment of a distributed network D2D connection, may also be obtained D2D distributed relay maximum number of network connections, to limit the D2D connection when the UE establishes a relay used in the channel number less than or equal the maximum number of the relay.

[0145] 需要说明的是,最大中继数可以是基站通过广播信令或其他专用信令下发给UE的,也可以是UE预配置的参数,还可以是协议定义的参数,具体方式此处不做限定。 [0145] Incidentally, the maximum number of relays may be other base station through broadcast signaling or dedicated signaling sent to the UE, the UE may be preconfigured parameters may also be defined protocol parameters, this specific embodiment Department is not limited.

[0146] 进一步,作为另一个实施例,UE在建立D2D分布式网络连接前,还获取D2D分布式网络连接的最大连接数,UE在建立D2D连接之前,先判断自身的D2D连接数是否大于最大连接数,若不大于,则UE在信道上建立D2D连接。 [0146] Further, as another example, the UE before creating a distributed network D2D connection, also acquires the maximum number of connections D2D distributed network connection, the UE before the D2D connection establishment, the first judging whether D2D greater than the maximum number of connections connections, if not greater than, the D2D connection establishment, the UE channel.

[0147] 需要说明的是,最大连接数可以是基站通过广播信令或其他专用信令下发给UE的,也可以是UE预配置的参数,还可以是协议定义的参数,具体方式此处不做限定。 [0147] Incidentally, the maximum number of connections may be broadcast by the base station via dedicated signaling or other signaling sent to the UE, the UE may be preconfigured parameters may also be defined by the protocol parameters, the specific embodiment herein which is not limited.

[0148] 进一步,作为另一个实施例,若在基站控制的D2D分布式网络建网模式下,UE在对信道进行测量后,将按照预先定义的测量结果上报参数要求,向基站上报信道测量结果。 [0148] Further, as another example, if at D2D distributed network networking model base control, the UE after the channel is measured, the reporting parameters required according to the measurement results of predefined reports channel measurement result to the base station . 具体的,预先定义的测量结果上报参数包括上报时间,上报格式等。 Specifically, the measurement reporting parameters include a predefined time reporting, reporting format.
