[0055]相对于现有技术的以SA(Scheduling assignment,调度分配)信息的接收功率或能量来进行调度的方式而言,本发明具体实施例通过用于数据传输的时频传输资源单位上的接收功率或能量来调度用于数据传输的第二时频传输资源,能够提高标识的数据传输占用资源的能量的精度,减少与实际的数据传输占用资源的能量的偏差,提高资源调度的准确性。 [0055] The prior art with respect to SA (Scheduling assignment, scheduling assignment) mode received power or energy scheduling information, the specific embodiments of the present invention for data transmission through the transmission frequency resource units the second received power or energy scheduling for data transmission frequency transmission resources, it is possible to improve the accuracy of data transmission occupies energy resource identifier, reducing the energy deviation of the actual data transmission occupies resources, improve the accuracy of resource scheduling .

[0056]其中,所述时频传输资源单位为子带或物理资源块PRB,通过确定每一个时频传输资源单位上的接收功率或能量。 [0056] wherein the time-frequency transmission resource unit or sub-bands of PRBs physical resource blocks, each time by determining the received power or energy frequency on the transmission resource unit.

[0057]目前,在LTE-based V2V技术中,确定采用基于LTE D2D的方式进行改进,其中属于控制信息的调度分配(SA)信息与数据信息(Data)是通过不同的信道进行传输,接收端通过检测控制信道中携带的SA信息,再根据SA信息中携带的信息进行数据信息的接收。 [0057] Currently, in the LTE-based V2V art, it is determined using the improved based LTE D2D manner, which belongs to the control scheduling assignment information (SA) information and data information (Data) is transmitted through a different channel, the receiving end SA information carried by the control channel detection, then the received data information according to the information carried in the SA message. 而在进行资源选择时,可存在两种方式,一种为用户设备UE自发进行,另一种为基站辅助进行。 During the resource selection, there may be two ways, one for the user equipment UE spontaneously, another base station assisted. [0058]相应的,参见图6A和图6B所示,本发明实施例中,所述资源调度方法可由第一移动通信终端执行,所述第一移动通信终端根据收集到的信息自发地为自身分配传输资源,所述资源调度方法也可由基站E-UTRAN执行,所述基站通过收集到的信息为第一移动通信终端分配传输资源,并将分配结果下发至所述第一移动通信终端。 [0058] Accordingly, 6A and 6B, in the embodiment, the resource scheduling method by a mobile communication terminal performs a first embodiment of the present invention, the first mobile communication terminal according to the collected information for their own spontaneous allocation of transmission resources, the resource scheduling method can also be performed E-UTRAN base station, the base station allocates the information collected to the mobile communication terminal a first transmission resource, and sends the first mobile communication terminal to assign the next result.

[0060]本发明实施例中,在通过SA的接收功率或能量的测量结果来获取数据传输占用资源的接收功率或能量时,参见图7所示,所述步骤53具体包括: [0060] The embodiments of the present invention, upon receiving power or energy to obtain the data transmission resources occupied by measurements of received power or energy SA, see figure, step 753 specifically comprises:

[0061]步骤71,获取所述第一移动通信终端在承载所述调度分配信息的第二时频传输资源上的第二接收功率或能量; [0061] Step 71, the first mobile communication terminal acquires a second pilot received power or energy transmission resource on the second carrier when the scheduling assignment information;

[0062]步骤72,根据所述第二接收功率或能量确定所述第一接收功率或能量; [0062] Step 72, according to the second determining received power or energy or power of the first received energy;

[0063]其中,所述第一接收功率或能量为所述第二接收功率或能量与A1/K1的乘积,所述A1为所述第二移动通信终端发送数据时的第一发射功率或能量与发送所述调度分配信息的第二发射功率或能量的比值; [0063] wherein, the first received power or energy or power to the second energy receiving A1 / K1 product, a first transmit power or energy of the transmission data A1 to the second mobile communication terminal ratio of the second transmit power or energy transmission and the scheduling assignment information;

[0065]下面,通过具体实例对上述功率或能量确定步骤进行详细说明。 [0065] Next, specific examples by the step of determining said power or energy to be described in detail. 其中,下面实例均是以功率确定为例来说明的,但同样适用于能量确定。 Wherein, the following example is provided to illustrate an example of determining the power, but the same applies to the energy determination.

[0066]实例一 [0066] Examples of a

[0067] 参见图2所示,当SA和Data的传输位于不同的子帧时,第一移动通信终端UE0在接收到其他移动通信终端UE'发送的SA信息的时候,数据的传输还没有发生,因此只能通过SA 的接收功率测量结果来标识在后续数据传输占用的时频传输资源的接收功率。 [0067] Referring to FIG. 2, when SA and Data transmission in different subframes, the first mobile communication terminal at the time of receiving the UE0 SA information other mobile communication terminal UE 'transmitted, data transmission has not occurred , it can only be identified when the received power in a subsequent data transmission frequency transmission resources occupied by received power measurement results SA. 同时,在SA 接收成功的情况下,从SA信息中可以获取关联的数据传输占用的PRB个数。 Meanwhile, in the case of successful reception of the SA, the number of PRB can acquire data transmitted from the associated occupancy information SA.

[0068]假设,SA的传输占用N个PRB,而关联的数据传输占用K个子带(时频传输资源单位),每个子带包含M个PRB,UE0接收到UE'的SA的功率测量的结果为P_sa(第二接收功率), 对应的数据传输占用的时频传输资源的(以M个PRB(即子带)为粒度)的功率SP_data_ subband(第一接收功率)。 Results [0068] Suppose the transmission SA occupies N number of PRBs, the data transmission associated occupancy K subbands (transmission resource unit frequency), each subband contains M PRB, UE0 received UE 'power measurement of the SA is P_sa (second received power), when the corresponding data transfer resources occupied by the transmission frequency power SP_data_ subband (first received power) (in M number of PRBs (i.e. subbands) granularity) of.

[0069]情况一:SA传输与数据传输分配相同的功率 [0069] where a: SA data transmission and transmission power allocation of the same

[0070]其中,该情况一例如为SA传输与数据传输都是以IT的全部功率进行发送,g卩Al = 1,K1=K。 [0070] wherein, for example, is the case in a full power transmission SA IT is to transmit the data transmission, g Jie Al = 1, K1 = K. 那么,可以得到: So, you can get:

[0071] UE0在数据传输所占用的资源上接收的总的功率为P_data = P_sa,而在每个子带上接收的功率就为?_(1&amp;13_3111^311(3 = ?_(^^&amp;/1( = ?_3&amp;/1(,即: [0071] The total power UE0 received on resource data transmission occupied for P_data = P_sa, the band received at each of the sub power on is _ (1 & amp;? 13_3111 ^ 311 (3 = _ (^^ & amp? ?; / 1 (= _3 & amp; / 1 (, namely:

[0072] P—data—subband=P—sa*Al/Kl。 [0072] P-data-subband = P-sa * Al / Kl.

[0073] 情况二:SA传输和关联的数据传输之间发送的功率是不相的 [0073] Case 2: the transmission power of the transmission between the data transmission SA and the associated phase are not

[0074]其中,该情况二例如为SA发送功率与数据发送功率之间的比值是a: ;L,即A1 = 1/a, K1=K。 [0074] wherein, for example, the case where two transmission power ratio between the power of the data transmission SA is a:; L, i.e., A1 = 1 / a, K1 = K. 那么,可以得到: So, you can get:

[0075] UE0在数据传输所占用的资源上接收的总的功率为P_data = P_sa/a,而在每个子带上接收的功率就为P_data_subband = P_data/K = P_saAa*K),目卩P_data_subband = P_ sa*Al/Kl〇 [0075] The total power received by UE0 data transmission on the resource is occupied P_data = P_sa / a, and each sub-band received power is on P_data_subband = P_data / K = P_saAa * K), Jie mesh P_data_subband = P_ sa * Al / Kl〇

[0076] 这种情况下,需要通过信令指示SA发送功率和data发送功率之间的偏差,而所述信令可以通过SA携带,也可以通过高层信令配置。 [0076] In this case, by indicating a signaling SA difference between the transmit power and power transmission data, and the signaling can carry SA, may also be configured by higher layer signaling.

[0077] 实例二 [0077] Example Two

[0078] 参见图3所示,SA和数据的传输位于相同的子帧,其中在数据传输占用的时频传输资源上的接收功率可以通过接收到的SA的功率测量结果获得。 [0078] Referring to Figure 3, the transmission SA and data in the same sub-frame, wherein the received power on pilot during a data transfer resources occupied by the transmission power measurement of the received SA is obtained.

[0079] 假设,SA的传输占用N个PRB,而关联的数据传输占用K个子带,每个子带包含M个PRB,UE0接收到UE/的SA的功率测量的结果为P_sa(第二接收功率),在对应的数据传输占用资源(以M个PRB (即子带)为粒度)上的接收功率SP_data_subband (第一接收功率)。 [0079] Suppose, SA transmission occupies N number of PRBs, and the associated data transmission occupies K subbands, each subband contains M of PRBs, SA measurement result of the power of the received UE0 UE / is P_sa (second received power ), corresponding to the footprint data transmission (number of PRBs to M (i.e., subband) of the received power SP_data_subband (first received power) on particle size).

[0080] 情况一:SA传输与数据传输采用按照PRB等功率分配的方法 [0080] where a: SA transmission and a data transmission method according to the PRB allocated equal power

[0081] 这种情况下,SA发送功率与数据发送功率之间的比值N/(M*K),即A1 = (M*K)/N,K1 =K,其处理过程如下所述: [0081] In this case, SA N ratio of the transmission power and data between the power transmission / (M * K), i.e., A1 = (M * K) / N, K1 = K, that the process is as follows:

[0082] 计算每个PRB上的SA的接收功率为P_sa_rb=P_sa/N; [0082] SA calculation on the received power of each PRB P_sa_rb = P_sa / N;

[0083] 计算传输数据的时频传输资源中,在每个子带上的接收功率如下: When the [0083] calculated frequency transmission resources for transmitting data, the received power on each subband as follows:

[0084] P—data—subband=P—sa—rb*M=P—sa*M/N。 [0084] P-data-subband = P-sa-rb * M = P-sa * M / N.

[0085] 即: [0085] That is:

[0086] P—data—subband=P—sa*Al/Kl。 [0086] P-data-subband = P-sa * Al / Kl.

[0087] 情况二:SA传输和关联的数据传输的发送功率不同 [0087] Case 2: the transmission power of the data transmitted and associated with different transmission SA

[0088]假定用于SA传输的PRB上的发送功率与用于数据传输的PRB上的发送功率的比值是a: 1,则SA发送功率与数据发送功率的比值为:(a*N)/(M*K),则: [0088] assumed that the transmission power ratio of the transmission SA PRB for the transmission power for data transmission on the PRB is a: 1, the ratio of the transmit power and data SA transmission power of: (a * N) / (M * K), then:

[0089] Al = (M*K)/(a*N) [0089] Al = (M * K) / (a ​​* N)

[0090] Kl=K〇 [0090] Kl = K〇

[0091] 由此可以得到: [0091] can be obtained:

[0092]传输SA的PRB上的接收功率P_sa_rl^P_sa/N,而传输数据的PRB上的接收功率P_ data_rbSP_sa_rb/a,则传输数据的子带上接收的功率P_data_subbandSP_data_rb*M= P_sa*M/(N*a),即: [0092] PRB on the received power of the transmission SA P_sa_rl ^ P_sa / N, and reception power P_ data_rbSP_sa_rb PRB to transmit data on / a, the sub-band of the transmission data received power P_data_subbandSP_data_rb * M = P_sa * M / ( N * a), namely:

[0093] P_data_subband = P_sa*Al/Kl。 [0093] P_data_subband = P_sa * Al / Kl.

[0094]这种情况下,需要通过信令指示传输SA的PRB上的发送功率和传输数据的PRB上的发送功率之间的偏差,而所述信令可以通过SA携带,也可以通过高层信令配置。 [0094] In this case, the deviation between the transmission power of the transmission power and transmission data PRB on the need to transmit signaling indicates a PRB SA, SA and carried by the signaling, or by high-level channel order configuration.

[0095]本发明实施例中,当所述第一时频传输资源与承载所述调度分配信息的第二时频传输资源在同一子帧时,还可直接获取数据传输占用资源的接收功率或能量,具体的,参见图8所示,所述步骤53具体包括: [0095] received power or embodiment of the present invention, when a second time when the first carrier frequency transmission resources and the scheduling assignment information of frequency resources at the same transmission sub-frame, also available direct data transfer resources occupied energy, specifically, referring to Figure, the step 853 specifically comprises:

[0096]步骤81,检测所述第一移动通信终端在所述第一时频传输资源上的第三接收功率或能量; [0096] Step 81, the first mobile communication terminal detecting a first time-frequency energy on the third received power or the transmission resources;

[0097]步骤82,根据所述第三接收功率或能量确定所述第一接收功率或能量; [0097] Step 82, determining the first received power or energy based on the third received power or energy;

[0098]其中,所述第一接收功率或能量为第三接收功率/K1,所述K1为所述第一时频传输资源所包括的时频传输资源单位的数量。 [0098] wherein the first receiving power or energy of the third receiving power / K1, the number of transmission resource units when the K1 is a first time-frequency resource comprises transmitting frequency.

[0099]举例来说,参见图3所示,SA和数据的传输位于相同的子帧。 [0099] For example, referring to FIG. 3, the transmission SA and data in the same subframe. 假设,SA的传输占用N 个PRB,而关联的数据传输占用K个子带,每个子带包含M个PRB,终端在数据传输所占用的资源上的总接收功率为P_data(第三接收功率),则在传输数据的PRB上的接收功率P_data_rb 为:P_data/(K*M)。 Suppose, the transmission SA occupies N number of PRBs, and the associated data transmission occupies K subbands, each subband contains M of PRBs, the total received power of the terminal on the resource occupied by the data transmission is P_data (third receiving power), P_data_rb the reception power of data transmitted on the PRB is: P_data / (K * M).

[0100] 因此传输数据在子带上的接收功率P_data_subband为:P_data_rb*M=P_data/K, 即P—data_subband = P_data/K1。 [0100] Thus in transmitting data received power P_data_subband subbands is: P_data_rb * M = P_data / K, i.e., P-data_subband = P_data / K1.

[01 01 ]具体的,如图4所示,SA传输和数据传输位于相同的子帧,但是SA中既包含当前数据传输的资源指示,也包含下一次传输的资源指示,其中相同标识区域数据传输表示的是对同一数据的初传和重传。 [0101] Specifically, as shown in FIG, SA and data transmission in the same sub-frame, but contains both SA indicating current data transmission resources is also included in the next transmission resource indication, wherein the same identification data area 4 transmitting the same data is represented by the initial transmission and retransmission. 其中,UEO总是希望根据当前子帧的测量,获取当前SA信息中指示的下一次数据传输的功率,例如如图4所示的虚线框所指的子帧41中,SA指示的当前子帧中数据传输占用的第一资源42中的子带的个数与下一次数据传输占用的第二资源43中的子带的个数是不同的,因此也需要根据在当前子帧测量到的,传输数据在子带上的接收功来确定下一次传输数据在子带上的接收功如果当前子帧中的数据传输占用的子带个数为K1,下一次数据传输占用的子带个数为K2,那么P_data_subband_2 = P_data_subband_l*K1/K2。 Wherein, according to the UEO always want to measure the current sub-frame, a data transmission power acquires the current SA information indicated in the dashed box in FIG. 4, for example, the sub-frame 41 shown in FIG indicated, an indication of the current sub-frame SA the number of the number in the first data transmission resource occupied by the 42 sub-subbands in the next 43 second data transfer resources occupied band is different, and therefore need to be measured in the current sub-frame, and transmitting the received data to determine the power of the subbands in the first transmission of data with the number of sub-subbands received power if the data transmission in the current subframe is occupied by K1, the number of sub-band occupied by the next data transmission is K2, then P_data_subband_2 = P_data_subband_l * K1 / K2.

[0102]本发明实施例中,参见图9所示,所述步骤54具体包括: Embodiment, referring to FIG., The step 954 comprises the [0102] embodiment of the present invention:

[0103] 步骤91,根据所述第一移动通信终端在所述第一时频传输资源的每一个时频传输资源单位上的第一接收功率或能量和预定策略选择目标子帧; [0103] Step 91, according to each of the first mobile communication terminal during a first time-frequency transmission resources in the first reception power or energy and a predetermined policy on a target frequency transmission resource unit selected subframe;

[0104] 步骤92,获取所述第一移动通信终端在承载所述目标子帧对应的所述调度分配信息的第三时频传输资源上的第三接收功率或能量; [0104] Step 92, the first mobile communication terminal acquired at the target carrier subframe scheduling assignment information corresponding to the third received power or energy in the third frequency transmission resources;

[0105] 步骤93,根据第三接收功率或能量确定所述目标子帧中每一个时频传输资源单位是否可用; [0105] Step 93, the target is determined for each subframe transmission time-frequency resource units are available in accordance with the third received power or energy;

[0106] 步骤94,根据所述目标子帧中每一个时频传输资源单位是否可用的信息调度所述目标时频传输资源。 When [0106] Step 94, according to the scheduling information of the target sub-frame of the target transmission resource units are available in each time-frequency resource transmission frequency.

[0107]在UE自发的选择资源的方式中,UE需要感知资源的占用情况,从而进行资源的选择,通常来说有两种方式:一种是根据接收到的其它UE的SA信息,获知其它UE的数据传输占用的资源指示,从而在未被占用的传输资源中选择传输的资源;另一种是直接在数据传输的资源上进行功率检测,如果功率高于一定的门限,那么认为对应的传输资源是被占用的, 在此基础上,选择未被占用的传输资源进行数据的传输。 [0107] In the selection of resources of the UE in the spontaneous, UE needs to detect the occupancy of resources to selected resources, it generally two ways: one is received SA information according to the other UE, other known indicating a data transmission resources occupied by the UE, transmission resources to select transmission resources in an unoccupied; the other is detected directly on the power transmission resource data, if the power is above a certain threshold, so that the corresponding transmission resources are occupied, on this basis, select an unoccupied transmission resources for data transmission. 在第一种方式中,如果数据传输与关联的SA的传输位于同一子帧,那么UE需要根据当前的感知确定后续一段时间内资源是否被占用,因此需要知道数据传输持续占用的时间或者周期,从而确定未来一段时间内的传输资源的占用情况,同理对于基于传输资源的能量检测,也需要知道数据传输持续占用的时间或者周期,从而确定未来一段时间内的传输资源的占用情况。 In a first aspect, the transmission data transmission associated with the SA in the same subframe, the UE needs to determine whether the resource is occupied within a subsequent period of time based on current perception, it is necessary to know the time occupied by the data transmission duration or period, thereby determining the occupancy of the transmission resources in the next period of time, for the same reason the energy transmission resource based detection, also needs to know the time occupied by the data transmission duration or period, to determine the occupancy of the transmission resources in the next period of time.

[0108]简单来说,如图1所示,UE需要根据能量检测或者SA的检测以及数据传输持续占用资源的时间或者周期来构建未来一定数量的子帧的资源占用情况,从而在选择空闲的资源进行传输。 [0108] Briefly, as shown, the UE needs to build future resource consumption of a number of sub-frames according to the energy detected 1 or SA is detected and the data transmission duration or period of time occupied resources so that an idle selected resources for transmission. 图1中标识了UE 1、UE2和UE3传输资源占用的情况,UE4如果需要进行数据传输,可以在空闲的资源中选择资源。 Figure 1 identifies the situation UE 1, UE2, and UE3 occupied transmission resources, the UE4 data transmission if necessary, can be selected resource in the idle resource. 或者进一步的可以通过SA检测或能量检测的方式获知哪个子帧上的干扰小(即子帧中对应的接收功率或能量的和值小),并结合预定策略,选择一个或多个干扰较小的目标子帧。 Or further may be learned by SA or energy detecting small detectable manner (i.e., sub-frame corresponding to the received power or energy value and small) interference on a sub-frame which, in conjunction with a predetermined policy, select one or more small interfering target sub-frame. 其中,所述预定策略例如为选择两个、三个或四个等目标子帧。 Wherein the predefined selection policy is, for example two, three or four targets subframes. 例如,在图1中,UE4可以选择第一个子帧和最后一个子帧(虚线所框的子帧)进行传输资源的传输。 For example, in FIG. 1, UE4 may select the first subframe and a last subframe (subframe broken line block) for transmission of the transmission resources.

[0109] 在确定能量分布之后,如何选择目标子帧可以有多种方式,如选择功率和最小的子帧,也可以按照功率和从小到大的顺序,选择多个子帧,而选择的子帧的数量可以预先确定,也可以根据功率和超过预定门限的子帧数量来确定,在此不一一描述。 [0109] After determining the energy distribution, how to select the target sub-frame may be a variety of ways, such as selecting the smallest sub-frame and power, and power can be in accordance with the order from small to large, selecting a plurality of subframes, a subframe selected the number may be determined in advance, may be determined according to the number and the sub-frame power exceeds a predetermined threshold, are not described one by one here.

[0110] 本发明实施例中,当所述第三时频传输资源与所述第三时频传输资源承载的调度分配信息所指示的第四时频传输资源在同一子帧时,所述第三接收功率或能量为:第四接收功率或能量与A2的比值; 其中:所述第四接收功率或能量为所述第一移动通信终端在所述第四时频传输资源上的接收功率或能量; [0110] Example embodiments of the present invention, the time-frequency transmission resources and the third fourth-frequency transmission resource allocation information for scheduling transmission resources indicated by the frequency of the carrier when the third sub-frame at the same time, the first three received power or energy: a fourth ratio of received power or energy and A2; wherein: said fourth received power or energy to the first mobile communication terminal received power on pilot transmission resources when the fourth or energy;

[0112]所述A2为所述第二移动通信终端在所述第四时频传输资源的发射功率或能量与所述第二移动通信终端在所述第三时频传输资源上的发射功率或能量的比值。 [0112] A2 is the second mobile communication terminal to the transmit power of pilot transmit power or energy transmission resources and the second mobile communication terminal when the third frequency transmission resources when the fourth or energy ratio.

[0113]上述方式中,通过数据的接收功率检测结果来获取SA的接收功率能够得到更加准确的SA接收功率结果,原因如下。 [0113] In the above embodiment, SA acquired by the reception power detection result reception power data can be obtained more accurate results SA reception power, for the following reasons.

[0114]相对而言,数据所占用的资源远大于SA所占用的资源,因此接收端对数据的接收功率结果会更加准确或者说误差更小,而利用误差更小的检测结果进行计算得到的SA接收功率会更加准确。 [0114] In contrast, the resources occupied by the data is much larger than the resources occupied by SA, the receiving end receives the result of the power of the data will be more accurate or error is smaller, but the detection result with a smaller error calculated SA received power will be more accurate.

[0115]现有技术中,在资源分配中终端可以根据SA接收的能量或功率,来判断当前接收到的SA指示的传输资源是否属于需要有效规避的传输资源。 [0115] In the prior art, the allocation of resources in the terminal SA may receive power or energy, to determine whether the currently received transmission resource indicated by SA belonging to effectively avoid the transmission resources needed. 例如设定一个SA的功率门限, 如果接收到的SA的功率高于所述功率门限,那么认为接收的SA指示的传输资源是需要进行规避的传输资源,否则认为接收的SA指示的传输资源是空闲的。 For example, set a power threshold of SA, SA's power If the received power is above the threshold, it is considered an indication of transmission resource SA received is needed to avoid the transmission of resources, or that the transmission resource SA indication is received free.

[0116]上述机制在负载比较高的时候,可以有效的提高资源分配的效率。 [0116] In the above-described mechanism when the load is relatively high, can effectively improve the efficiency of resource allocation. 但由于SA和数据传输可能位于相同子帧,也可能位于不同子帧,而在SA和数据传输位于相同子帧的情况下,数据传输占用的频域资源的大小都会发生变化,同时还有各种信道衰落的影响等,这些都会影响SA的接收能量,从而导致使用一个统一的门限无法进行正确的判别。 However, since SA and data may be located in the same sub-frame, it may also be located in different sub frames, and the SA in the case where the data transfer is located in the same sub-frame, the size of the frequency domain resource occupied by the data transmission will change, as well as various impact of channel fading and other species, which will affect the received energy SA, resulting in the use of a single threshold can not be correct discrimination.

[0117] 对此举例如下。 [0117] Examples of this are as follows.

[0118]当SA和数据在不同子帧传输时,SA可以独占所有的发射功率,而当SA和数据在同一子帧传输时,SA需要和数据共享发射功率,在这两种情形下,依据SA的接收功率进行资源是否占用的判断,使用同一门限很明显是不合理的。 [0118] When the SA and the data in different sub-frame transmission, SA can monopolize all transmit power, and when the SA and data transmission in the same sub-frame, and data sharing SA transmit power required, in both cases, based on SA received power to judge whether the resources used, using the same threshold is clearly unreasonable. 所以,本发明实施例中,可对目标子帧对应的SA信息进行划分,例如划分为第一模式的SA信息(对应在同一子帧情况)和第二模式的SA信息(对应不在同一子帧情况),并统一进行SA的能量归一化处理(把不同的情形统一到一个统一的标准下进行考量),以减小所述目标子帧对应的所述SA信息由于模式差异导致的接收功率或能量的差异。 Therefore, the present embodiment of the invention, may be divided into subframes corresponding to the SA information to a target, for example, is divided into a first mode SA information (corresponding to the case where the same sub-frame) SA information and the second mode (not in the same sub-frame corresponding to ), the energy of the SA and consolidated normalized (to unify the different situations under consideration for a unified standard), to reduce the SA information corresponding to the sub-frame because the target reception power mode caused by differences or differences in energy.

[0119]具体的,本发明实施例中,所述目标子帧对应的所述调度分配信息包括: [0119] Specifically, the embodiment of the present invention, the scheduling assignment information corresponding to the target sub-frame comprises:

[0120]第一模式的调度分配信息,所在的第五时频传输资源和所指示的时频传输资源在同一子巾贞;和 [0120] scheduling assignment information of the first mode, and when the fifth frequency transmission resource is indicated by the same sub-frequency transmission resource towels Zhen; and

[0121]第二模式的调度分配信息,所在的第六时频传输资源和所指示的时频传输资源不在同一子帧。 [0121] a second mode of scheduling assignment information, and time-frequency transmission resource indicated by the sixth frequency where the transmission resource is not in the same sub-frame.

[0122] 相应的,参见图10所示,所述步骤93具体包括: [0122] Accordingly, as shown in FIG. Referring to the step 1093 specifically comprises:

[0123]步骤101:计算同一中间场景中,第一模式的调度分配信息的第五接收功率或能量对应的第七功率或能量,以及第二模式的调度分配信息的第六接收功率或能量对应的第八功率或能量; [0123] Step 101: Calculate the same intermediate scenario, the seventh power or energy receiving scheduling assignment information according to a fifth power or energy corresponding to the first mode, and receiving scheduling assignment information to the sixth power or energy corresponding to the second mode eighth power or energy;

[0124]换句话说,本发明具体实施例中,步骤101中,对所述第一移动通信终端在所述第五时频传输资源上的第五接收功率或能量和在所述第六时频传输资源上的第六接收功率或能量进行转换,得到转换后的接收功率或能量,减小了所述目标子帧对应的所述调度分配信息由于模式差异导致的接收功率或能量的差异; [0124] In other words, the specific embodiments of the present invention, in step 101, the first mobile communication terminal of the fifth frequency energy on the received power or transmission resources when the fifth and the sixth time sixth receiving power or energy in the frequency conversion transmission resource, to obtain the received power or energy converted, reduces the scheduling assignment information of the target sub-frame corresponding to the difference in received power or energy resulting from the pattern due to the difference;

[0125]步骤102:利用转换得到的第七接收功率或能量以及第八接收功率或能量确定所述目标子帧中每一个时频传输资源单位是否可用。 [0125] Step 102: determining the target sub-frame each time-frequency resource units are available using the transmission received power or energy seventh and eighth converted received power or energy.

[0126]具体的,对所述第五接收功率或能量进行转换得到的接收功率或能量为: Received power or energy [0126] Specifically, the fifth receiving power or energy conversion is obtained:

[0127]第五接收功率或能量*N/(N+M); [0127] Fifth received power or energy * N / (N + M);

[0128]对所述第六接收功率或能量进行转换得到的接收功率或能量为: [0128] received power or energy of said sixth received power or energy conversion is obtained:

[0129] (1+A3)*第六接收功率或能量*NAN+M);或者 [0129] (1 + A3) * sixth receiving power or energy * NAN + M); or

[0130] (1+1/A3)*第七接收功率或能量*N/(N+M); [0130] (1 + 1 / A3) * seventh received power or energy * N / (N + M);

[0131]其中,所述N为预设的所述调度分配信息占用的时频传输资源单位数量,所述|!为预设的数据传输占用的时频传输资源单位数量,A3为所述第二移动通信终端发送数据的发射功率或能量与发送所述第二模式的调度分配信息的发射功率或能量的比值,所述第七接收功率或能量为所述第一移动通信终端在所述第二模式的调度分配信息所指示的时频传输资源上的接收功率或能量。 [0131] wherein the N number of frequency transmission resource unit, when the predetermined scheduling assignment information of the occupied |! Number of transmission resource unit is occupied by a preset data transmission frequency, A3 of the first the ratio of the transmit power or transmit power or energy scheduling assignment information to the second mode transmits energy to the second mobile communication terminal transmits data, the seventh received power or energy of the first mobile communication terminal in the first when the second mode the scheduling assignment information indicated by the received power or energy frequency on the transmission resource.

[0132]这样,利用SA接收能量的归一化结果进行门限判断,如果高于SA接收门限,则表示当前SA信息中指示的数据传输的资源在后续一段时间或者按照一定的周期持续占用,否则数据传输的资源认为是空闲的,可有效提高资源分配的性能。 [0132] Thus, using the SA received energy normalized results for threshold judgment, if it exceeds SA receiving threshold, then the data transfer current SA information in the resource indicated in a subsequent period of time or duration occupied in a certain period, or data transmission resource that is free, can improve the performance of resource allocation.

[0133] 下面,通过具体实例对SA的能量归一化处理进行说明。 [0133] Next, specific examples of the SA by the energy normalization process will be described.

[0134] 这里,SA功率归一化的基准为:SA占用N个PRB,数据传输占用一个子带(M个PRB,gp 预设的数据传输占用的时频传输资源单位数量)的情况下,SA和数据的发送基于PRB等功率分配。 N number of PRBs occupied by the SA, the data transmission occupies a subband (M number of PRBs, when the number of transmission resource units occupying gp preset data transmission frequency), the: [0134] Here, power normalization SA reference to SA and data transmission based on PRB allocated equal power.

[0135] 实例一 [0135] Examples of a

[0136] SA和关联数据位于不同子帧,并假定SA和数据采用等功率发送,归一化的处理可以采用将SA的接收的总功率按PRB的个数等功率的分散在SA占用的N个PRB和数据传输占用的M个PRB(—个子带)中,然后计算N个PRB上的SA的接收功率,归一化之后的SA功率为:P_ sa*N/(N+M)〇[0137]实例二 [0136] SA and associated data in different sub-frames, and assumes equal power SA and data transmission, the normalization process of the dispersion power of the total power received by the SA SA PRB is the number of occupied or the like may be employed N PRB pairs and the data transmission occupies the M PRB (- subbands), and then calculating the reception power SA on the N PRB, SA power after normalization is: P_ sa * N / (N + M) square [ 0137] example two

[0138] SA和关联数据位于相同子帧,SA占用N个PRB,数据传输占用K个子带,每个子带包含M个PRB,并假定SA和数据传输按照PRB等功率分配,g卩A3= (K*M)/N,归一化的处理可以分为以SA功率测量结果P_sa为基础的归一化处理或者以P_data_subband为基础的归一化处理。 [0138] SA and associated data in the same subframe, SA occupies the N PRB, the data transmission occupies K subbands, each subband contains M PRB, and assumes SA and transfer data in the PRB equal power allocation, g Jie A3 = ( K * M) / N, the normalization process can be divided in a power measurement P_sa SA based or normalized based in P_data_subband normalization process.

[0139]具体过程详细说明如下。 [0139] The specific process described in detail below.

[0140]以SA能量测量?_似为基础的归一化处理过程包括如下步骤: [0140] In the power measuring SA _ like normalization process comprises the following steps based on?:

[0141] 根据P_sa,计算传输SA的PRB上的接收功率P_sa_rb为:P_sa/N; [0141] According P_sa, received power on the calculation of the transmission SA PRB P_sa_rb is: P_sa / N;

[0142]由于传输数据的PRB上的发送功率与传输SA的PRB上的发送功率相同的,所以,传输SA的PRB上的接收功率P_data_rb与传输数据的PRB上的接收功率P_data_rb也相同,即P_ sa—rb 等于P—data—rb; [0142] Since the same transmission power on the PRB transmission power and transmission SA on the PRB to transmit data, therefore, received power on the PRB reception power P_data_rb transmission data on the PRB transmission SA is P_data_rb same, i.e. P_ sa-rb equal to P-data-rb;

[0143] 在当前子帧SA和数据的总接收功率SP_sa_rb*(N+K*M) = (l+A3)*P_sa; [0143] The total received power in the current sub-frame SA and data SP_sa_rb * (N + K * M) = (l + A3) * P_sa;

[0144] 归一化的SA接收功率的结果为:(l+A3)*P_sa*N/(N+M)。 Results [0144] SA normalized received power as: (l + A3) * P_sa * N / (N + M).

[0145] &amp;P_data_subband为基础的归一化处理过程包括如下步骤: [0145] & amp; P_data_subband based normalization process comprising the steps of:

[0147]由于传输数据的PRB上的发送功率与传输SA的PRB上的发送功率相同的,所以,传输SA的PRB上的接收功率P_data_rb与传输数据的PRB上的接收功率P_data_rb也相同,即P_ sa—rb 等于P_data—rb; [0147] Since the same transmission power on the PRB transmission power and transmission SA on the PRB to transmit data, therefore, received power on the PRB reception power P_data_rb transmission data on the PRB transmission SA is P_data_rb same, i.e. P_ sa-rb equal P_data-rb;

[0148]当前子帧SA和数据的总接收功率Sp_data_rb*(N+K*M) = (l+A3)*P_sa; [0148] The current total reception power data and subframes SA Sp_data_rb * (N + K * M) = (l + A3) * P_sa;

[0149] 归一化的SA接收功率的结果为:(1+A3)*P_sa*N/(N+M)。 Results [0149] SA normalized received power is: (1 + A3) * P_sa * N / (N + M).
