Description

Method and device for transmitting broadcast message

Technical field

本发明涉及通信领域，尤其涉及一种广播消息的传输方法及装置。The present invention relates to the field of communications, and in particular, to a method and an apparatus for transmitting a broadcast message.

Background technique

跳频技术(Frequency-Hopping Spread Spectrum，FHSS)是指载波频率在一定范围内，按某种规律跳变，它是通信领域中的常用通信手段，可以有效的避开干扰，发挥通信效能。Frequency-Hopping Spread Spectrum (FHSS) refers to a carrier frequency that is within a certain range and hops according to a certain rule. It is a common communication method in the communication field, which can effectively avoid interference and exert communication efficiency.

具体的，可以将信道资源划分为时域资源和频域资源，如图1所示，每一帧内，在频域方向上又可以将频域资源划分为m个子载波，在时域方向上又可以将时域资源划分为n个时隙，而且，时隙之间设有一定时长的时隙间隔，于是，在一帧内就可以得到m*n个时频资源，假设UE与基站进行通信的一个周期内包含N帧，那么，就可以得到m*n个时频资源序列，例如，0号帧中的第一时频资源、第1帧中的第一时频资源以及第N-1帧中的第一时频资源为一个时频资源序列。Specifically, the channel resources may be divided into time domain resources and frequency domain resources. As shown in FIG. 1 , in each frame, the frequency domain resources may be divided into m subcarriers in the frequency domain direction, in the time domain direction. The time domain resource can be divided into n time slots, and a time slot interval of a certain duration is set between the time slots, so that m*n time-frequency resources can be obtained in one frame, assuming that the UE performs with the base station. If a period of communication includes N frames, then m*n time-frequency resource sequences can be obtained, for example, the first time-frequency resource in the frame 0, the first time-frequency resource in the first frame, and the N-th The first time-frequency resource in one frame is a time-frequency resource sequence.

在现有技术中，为了解决D2D(Device-to-Device)设备使用FDM(Frequency Division Multiplexing，频分多路复用)的方式进行广播通信时存在的半双工问题(即使用相同时域资源的不同UE无法互相通信)，可以使用下面的跳频方案对时频资源进行合理分配：In the prior art, in order to solve the half-duplex problem in which a D2D (Device-to-Device) device performs broadcast communication using FDM (Frequency Division Multiplexing), that is, the same time domain resource is used. Different UEs cannot communicate with each other), the following frequency hopping scheme can be used to reasonably allocate time-frequency resources:

i(0)＝0，1，...，m-1，j(0)＝0，1，...，n-1；i(0)=0,1,...,m-1,j(0)=0,1,...,n-1;

i(t)＝i(0)，j(t)＝j(0)+i(0)*t mod n；i(t)=i(0), j(t)=j(0)+i(0)*t mod n;

如图1所示，i(0)为任意UE在0号帧的频域资源位置，j(0)为该UE在0号帧的时域资源位置，i(t)为该UE在T号帧的频域资源位置，j(t)为该UE在T号帧的时域资源位置，也就是说，该UE在T号帧所使用的频时资源，是由它在0号帧的频时资源所决定的。 As shown in FIG. 1 , i(0) is the frequency domain resource location of any UE in frame 0, j(0) is the time domain resource location of the UE in frame 0, and i(t) is the T number of the UE. The frequency domain resource location of the frame, j(t) is the time domain resource location of the UE in the T frame, that is, the frequency resource used by the UE in the T frame is the frequency of the frame in the 0 frame. When resources are determined.

基于这种特定的广播通信方式，在每个周期(N帧)内使用不同的时频资源的两个UE至多在一个帧内具有相同的时域位置(即j(t)相同)，这样就保证了至少在其他N-1帧内，使用不同的时频资源的两个UE可以进行通信，如图1所示，分别使用第一时频资源和第四时频资源的两个UE只有在0号帧内位于相同的时隙内。Based on this particular broadcast communication method, two UEs using different time-frequency resources in each cycle (N frames) have at most the same time domain position in one frame (ie, j(t) is the same), thus It is ensured that two UEs using different time-frequency resources can communicate at least in other N-1 frames. As shown in FIG. 1, two UEs respectively using the first time-frequency resource and the fourth time-frequency resource are only in the UE. Frame 0 is located in the same time slot.

然而，由于时隙之间预留有一定时长的时隙间隔，所以，当使用相邻时域资源的两个UE进行数据收发时需要等待时隙间隔的时长之后才能进行，尤其是在一个时隙本身的时长较短，而导致时隙间隔占比增加的情况下，会很大程度上增加UE的通信速度，并造成了时频资源的浪费。However, since a time slot interval is reserved between time slots, when two UEs using adjacent time domain resources perform data transmission and reception, it is necessary to wait for the time interval of the time slot interval, especially at one time. When the slot itself has a short duration, and the slot interval ratio increases, the communication speed of the UE is greatly increased, and the time-frequency resource is wasted.

That is to say, in the N-1 frame, any two time domain resource locations of UEs using different time-frequency resources are separated by at least 3 time slots, since only The UEs with different time-frequency resources need to wait for the time slot interval when the UEs in the slot are transmitting and receiving the broadcast message. Therefore, any two UEs using different time-frequency resources in the present invention do not need to wait for the reserved time slot when transmitting and receiving broadcast messages. The transmission and reception operations of the broadcast message can be performed at intervals, which solves the problem that the communication speed is reduced and the time-frequency resources are wasted due to the reserved slot interval when the UE performs frequency hopping in the prior art.

detailed description

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

为了应用本发明的实施例提供一种广播消息的传输方法进行跳频，在每一帧内，如表1所示，可以将信道资源在水平的频域方向上划分为m个子载波i，在垂直的时域方向上划分为n个时隙组j，每一个时隙组中包含3个时隙k，其中，n为大于或等于3*m的素数，n＞m＞0。In order to apply the embodiments of the present invention, a method for transmitting a broadcast message is provided to perform a hopping Frequency, in each frame, as shown in Table 1, the channel resources can be divided into m subcarriers i in the horizontal frequency domain direction, and divided into n time slot groups j in the vertical time domain direction, each The slot group contains three slots k, where n is a prime number greater than or equal to 3*m, n>m>0.

表1Table 1

在现有技术中，当使用相邻时隙的两个UE(例如A和B)进行广播信息的收发时，需要等待预留的时隙间隔的时长之后才能收发广播信息，因此，当一个时隙本身的时长较短时(例如时隙为40毫秒，时隙间隔为20毫秒)，会导致时隙间隔占比增加，在很大程度上增加UE的通信速度，并造成了时频资源的浪费。In the prior art, when two UEs (for example, A and B) using adjacent time slots are used for transmitting and receiving broadcast information, it is necessary to wait for the reserved time slot interval before sending and receiving broadcast information, and therefore, when one time When the duration of the slot itself is short (for example, the time slot is 40 milliseconds and the time slot interval is 20 milliseconds), the slot interval ratio increases, which greatly increases the communication speed of the UE and causes time-frequency resources. waste.

在本发明中，如表1所示，将信道时频资源重新进行划分，将时域资源划分为时隙组和时隙组内的时隙，即通过序列对(j，k)区分时域资源位置，这样一来，当使用不同时频资源的两个UE(例如A和C)尽可能的在跳频周期(N个帧)中都不在同一个时隙组跳频时，UE之间进行广播信息的收发时就无需预留相邻时隙间的时隙间隔，提高通信速度的同时提高了时频资源的利用率。In the present invention, as shown in Table 1, the channel time-frequency resources are re-divided, and the time domain resources are divided into time slots and time slots in the time slot group, that is, the time domain is distinguished by the sequence pair (j, k). Resource location, such that when two UEs (eg, A and C) using different time-frequency resources are not hopping in the same slot group as much as possible in the hop period (N frames), between UEs When the broadcast information is sent and received, there is no need to reserve the time slot interval between adjacent time slots, thereby improving the communication speed and improving the utilization of time-frequency resources.

实施例一Embodiment 1

本发明的实施例提供一种广播消息的传输方法，如图2所示，包括：An embodiment of the present invention provides a method for transmitting a broadcast message, as shown in FIG. 2, including:

101、第一UE根据当前系统帧号T以及其他至少一个UE在T号帧之前使用的时频资源信息，确定第一UE在0号帧的时频资源信息，T为大于等于0的整数。 The first UE determines the time-frequency resource information of the first UE in the frame 0 according to the current system frame number T and the time-frequency resource information used by the at least one UE before the T-frame, and T is an integer greater than or equal to 0.

102、第一UE根据当前系统帧号T和第一UE在0号帧的频域资源位置，确定第一UE在T号帧的频域资源位置。102. The first UE determines, according to the current system frame number T and the frequency domain resource location of the first UE in frame 0, the frequency domain resource location of the first UE in the T frame.

103、第一UE根据当前系统帧号T和第一UE在0号帧的时频资源信息，确定第一UE在T号帧的时隙组位置和时隙位置，并确定第一UE在T号帧的时域资源位置，其中，在一个N帧的周期内，第一UE的时域资源位置与第二UE的时域资源位置有N-1次相隔至少3个时隙，该第二UE为其他至少一个UE中的任一个，N为大于1的整数。103. The first UE determines, according to the current system frame number T and the time-frequency resource information of the first UE in the frame 0, the slot group location and the slot position of the first UE in the T frame, and determines that the first UE is in the T The time domain resource location of the number frame, wherein the time domain resource location of the first UE and the time domain resource location of the second UE are separated by N-1 times by at least 3 time slots in the period of one N frame, the second The UE is any one of the other at least one UE, and N is an integer greater than one.

104、第一UE使用T号帧的频域资源位置和时域资源位置的资源发送第一UE的广播消息。104. The first UE sends a broadcast message of the first UE by using a frequency domain resource location of the T frame and a resource of the time domain resource location.

在步骤101中，该时频资源信息包括频域资源位置和时域资源位置，其中，该时域资源位置由时隙组位置和每一个时隙组内的时隙位置共同决定，该第一UE可以为D2D系统中所有UE中的任意一个。In step 101, the time-frequency resource information includes a frequency domain resource location and a time domain resource location, where the time domain resource location is jointly determined by the slot group location and the slot location in each slot group, the first The UE may be any of all UEs in the D2D system.

具体的，第一UE可以通过基站的系统广播获取当前的系统帧号T，另外，第一UE在T号帧之前，还会侦听其他UE在0号帧至T-1号帧发送各自的广播消息时，其他UE所使用的时频资源信息，即其他UE在0号帧至T-1号帧使用的频域资源位置i，以及时域资源位置(j，k)。进而，第一UE根据其他UE在T号帧之前使用的频域资源位置i，以及时域资源位置(j，k)，确定第一UE自己在第0号帧的时频资源信息，该时频资源信息包括第一UE的频域资源位置i(0)，以及时第一UE的时域资源位置(j(0)，k(0))。Specifically, the first UE may obtain the current system frame number T by using the system broadcast of the base station, and the first UE may also listen to other UEs to send the respective frames in the 0th frame to the T-1 frame before the T number frame. When broadcasting a message, time-frequency resource information used by other UEs, that is, a frequency domain resource position i used by other UEs in frames 0 to T-1, and a time domain resource location (j, k). Further, the first UE determines the time-frequency resource information of the first UE itself in the 0th frame according to the frequency domain resource location i used by the other UE before the T-frame and the time domain resource location (j, k). The frequency resource information includes a frequency domain resource location i(0) of the first UE, and a time domain resource location (j(0), k(0)) of the first UE.

例如，由于第一UE侦听其他UE在0号帧至T-1号帧发送各自的广播消息时所使用的时频资源信息，当某一时频资源从0号帧至T-1号帧一直没有UE占用时，第一UE便可确定该时频资源为自己发送广播信息时占用的时频资源，并确定自己在第0号帧的时频资源信息，即频域资源位置i(0)，以及时域资源位置(j(0)，k(0))。当然，如果当前的系统帧号T为0号帧时，即当前帧为第1帧，那么，第一UE可以直接根据基站或UE之间发送的系统广播确定自己在0号帧的时频资源信息。For example, when the first UE listens to time-frequency resource information used by other UEs to transmit respective broadcast messages in frame 0 to frame T-1, when a certain time-frequency resource is from frame 0 to frame T-1. When no UE is occupied, the first UE may determine the time-frequency resource occupied by the time-frequency resource for transmitting the broadcast information by itself, and determine the time-frequency resource information of the frame No. 0, that is, the frequency domain resource location i(0). And the time domain resource location (j(0), k(0)). Certainly, if the current system frame number T is the frame number 0, that is, the current frame is the first frame, the first UE may directly determine the system according to the system broadcast sent between the base station or the UE. Time-frequency resource information in frame 0.

在步骤102中，在确定第一UE在0号帧的频域资源位置i(0)，以及时第一UE的域资源位置(j(0)，k(0))之后，第一UE根据当前系统帧号T和第一UE在0号帧的频域资源位置，确定第一UE在T号帧的频域资源位置i(T)。In step 102, after determining that the first UE is in the frequency domain resource location i(0) of frame 0, and the domain resource location (j(0), k(0)) of the first UE, the first UE is based on The current system frame number T and the frequency domain resource location of the first UE in frame 0 determine the frequency domain resource location i(T) of the first UE in the T frame.

具体的，第一UE可以将第一UE在0号帧的频域资源位置i(0)，确定为第一UE在T号帧的频域资源位置i(T)；或者，第一UE将第一UE在0号帧的频域资源位置i(0)平移c*T个子载波后的频域资源位置，确定为第一UE在T号帧的频域资源位置i(T)，其中，c为大于0的整数。Specifically, the first UE may determine the frequency domain resource location i(0) of the first UE in the frame 0 frame as the frequency domain resource location i(T) of the first UE in the T number frame; or, the first UE will The frequency domain resource position after the first UE shifts the c*T subcarriers in the frequency domain resource position i(0) of the frame 0 is determined as the frequency domain resource position i(T) of the first UE in the T frame, where c is an integer greater than zero.

在步骤103中，在确定第一UE在0号帧的频域资源位置i(0)，以及时第一UE的域资源位置(j(0)，k(0))之后，第一UE根据第一UE在0号帧的频域资源位置i(0)，以及第一UE的时域资源位置(j(0)，k(0))，分别确定第一UE在T号帧的时隙组位置j(T)和时隙位置k(T)，这样，j(T)和k(T)便组成了第一UE在T号帧的时域资源位置。In step 103, after determining that the first UE is in the frequency domain resource location i(0) of frame 0, and the domain resource location (j(0), k(0)) of the first UE, the first UE is based on Determining, by the first UE, the frequency domain resource location i(0) of frame 0 and the time domain resource location of the first UE (j(0), k(0)), respectively determining the time slot of the first UE in the T frame The group position j(T) and the slot position k(T), such that j(T) and k(T) constitute the time domain resource location of the first UE in the T frame.

具体的，在确定第一UE在T号帧的时隙组位置j(T)时，第一UE可以以当前系统帧号T为参量，对第一UE在0号帧的频域资源位置和时域资源位置进行线性变换，以确定第一UE在T号帧的时隙组位置，以使得第一UE(设第一UE为A)在一个N帧的周期内的时域资源位置，与第二UE(设第二UE为B)的时域资源位置有N-1次相隔至少3个时隙，其中，该第二UE为其他UE中的任一个，也就是说，j_A(T)-j_B(T)在一个N帧的周期内至少有N-1次不为0。Specifically, when determining the slot group location j(T) of the first UE in the T frame, the first UE may use the current system frame number T as a parameter, and the frequency domain resource location of the first UE in the frame 0 frame. The time domain resource location is linearly transformed to determine a time slot group location of the first UE in the T number frame, such that the first UE (set the first UE is A) a time domain resource location within a period of one N frame, and The time domain resource location of the second UE (the second UE is B) has N-1 times separated by at least 3 time slots, wherein the second UE is any one of the other UEs, that is, j _A (T ) -j _B (T) is not 0 at least N-1 times in a period of N frames.

这样一来，任意两个使用不同时频资源的UE(例如A和B)在跳频周期(N个帧)中，可以尽可能的不在同一个时隙组中，那么，UE之间进行广播信息的收发时就无需预留相邻时隙间的时隙间隔，从而提高了通信速度，且提高了时频资源的利用率。In this way, any two UEs (eg, A and B) that use different time-frequency resources can be broadcasted between UEs in the same time slot group in the frequency hopping period (N frames). When the information is sent and received, there is no need to reserve the time slot interval between adjacent time slots, thereby improving the communication speed and improving the utilization of time-frequency resources.

进一步地，第一UE对第一UE在0号帧的频域资源位置和时域资源位置进行线性变换时，可以将第一UE在0号帧的时隙组位置平移L*T个时隙组后的时域资源位置，确定为第一UE在T号帧的时隙组位置，其中，L为第一UE在0号帧的时隙位置与第一UE在0号帧的频域资源位置共同决定的，L为大于等于0的整数。Further, when the first UE linearly transforms the frequency domain resource location and the time domain resource location of the No. 0 frame by the first UE, the first UE may be in the slot group location of the No. 0 frame. The time domain resource position after the L*T time slot group is translated, and is determined as the time slot group position of the first UE in the T number frame, where L is the first UE in the time slot position of the 0th frame and the first UE is The frequency domain resource location of frame 0 is determined in common, and L is an integer greater than or equal to zero.

在步骤104中，在第一UE确定了在T号帧的频域资源位置i(T)、时隙组位置j(T)和时隙位置k(T)之后，第一UE使用该频域资源位置i(T)、时隙组位置j(T)和时隙位置k(T)所指示的资源发送第一UE的广播消息。In step 104, after the first UE determines the frequency domain resource location i(T), the slot group location j(T), and the slot location k(T) of the T frame, the first UE uses the frequency domain. The resource indicated by the resource location i(T), the slot group location j(T), and the slot location k(T) transmits a broadcast message of the first UE.

本发明的实施例提供一种广播消息的传输方法，通过将时域资源位置划分为时隙组位置和时隙位置，这样一来，第一UE便可根据在0号帧时的隙组位置和时隙位置，确定第一UE在T号帧的时隙组位置和时隙位置，那么，在一个N帧的周期内，第一UE的时域资源位置与第二UE的时域资源位置有N-1次相隔至少3个时隙，也就是说，在N-1帧中，任意两个使用不同时频资源的UE的时域资源位置都至少间隔3个时隙，由于只有时隙相邻的UE进行广播消息收发时才需要等待时隙间隔，所以本发明中任意两个使用不同时频资源的UE在收发广播消息时，均无需等待预留的时隙间隔就可以进行广播消息的收发操作，解决了现有技术中UE进行跳频时由于预留时隙间隔所造成的通信速度下降以及时频资源浪费的问题。Embodiments of the present invention provide a method for transmitting a broadcast message, by dividing a time domain resource location into a slot group location and a slot location, so that the first UE can be based on the slot group position at frame 0. And the slot position, determining the slot group position and the slot position of the first UE in the T frame, then, in a period of one N frame, the time domain resource location of the first UE and the time domain resource location of the second UE There are at least 3 time slots separated by N-1 times, that is, in the N-1 frame, the time domain resource positions of any two UEs using different time-frequency resources are separated by at least 3 time slots, since only time slots are available. When a neighboring UE performs broadcast messaging, it needs to wait for a slot interval. Therefore, any two UEs using different time-frequency resources in the present invention can broadcast a message without waiting for a reserved slot interval. The transmitting and receiving operations solve the problem that the communication speed is reduced and the time-frequency resources are wasted due to the reserved slot interval when the UE performs frequency hopping in the prior art.

实施例二Embodiment 2

本发明的实施例提供一种广播消息的传输方法，如图3所示，包括：An embodiment of the present invention provides a method for transmitting a broadcast message, as shown in FIG. 3, including:

201、第一UE根据当前系统帧号T以及其他UE在T号帧之前使用的时频资源信息，确定第一UE在于T号帧对应的0号帧的频域资源位置、时隙组位置和时隙位置，T为大于等于0的整数；The first UE determines, according to the current system frame number T and the time-frequency resource information used by other UEs before the T-number frame, the frequency domain resource location, the time slot group location, and the first UE in the frame No. 0 corresponding to the T-frame. The slot position, T is an integer greater than or equal to 0;

202、第一UE将第一UE在0号帧的频域资源位置平移c*T个子载波后的频域资源位置，确定为第一UE在T号帧的频域资源位置，c为大于等于0的整数；202. The first UE determines, by using the frequency domain resource position of the first UE in the frequency domain resource position of the frame 0, the frequency domain resource position after the c*T subcarriers, where the first UE is in the frequency domain resource position of the T frame, and c is greater than or equal to An integer of 0;

203、第一UE以当前系统帧号T为参量，对第一UE在0号帧的频域资源位置和时域资源位置进行线性变换，以确定第一UE在T号帧的时隙组位置；203. The first UE uses the current system frame number T as a parameter, and the first UE is in frame 0. The frequency domain resource location and the time domain resource location are linearly transformed to determine a slot group location of the first UE in the T frame;

204、第一UE将第一UE在0号帧的时隙位置确定为第一UE在T号帧的时隙位置；204. The first UE determines, by the first UE, a slot position of the No. 0 frame as a slot position of the first UE in the T frame.

205、在T号帧时，第一UE使用步骤202至204中确定的T号帧的频域资源位置、时隙组位置和时隙位置所决定的时频资源信息发送第一UE的广播消息。205. In the T frame, the first UE sends the broadcast message of the first UE by using the time-frequency resource information determined by the frequency domain resource location, the slot group location, and the slot location determined by the T-frame determined in steps 202 to 204. .

在步骤201中，如表1所示，时频资源信息包括频域资源位置i和时域资源位置(j，k)，其中，时域资源位置(j，k)由时隙组位置j和每一个时隙组内的时隙位置k共同决定，为方便描述，以下实施例中以终端A作为第一UE，以终端B作为第二UE进行阐述。In step 201, as shown in Table 1, the time-frequency resource information includes a frequency domain resource location i and a time domain resource location (j, k), wherein the time domain resource location (j, k) is determined by the slot group location j and The slot positions k in each slot group are determined together. For convenience of description, in the following embodiments, terminal A is used as the first UE, and terminal B is used as the second UE.

具体的，第一UE可以通过基站的系统广播获取当前的系统帧号N，同时，第一UE在T号帧之前，还会侦听其他UE在0号帧至第T-1帧发送各自的广播消息时，其他UE所使用的时频资源信息，即其他UE在0号帧至第T-1帧使用的频域资源位置i，以及时域资源位置(j，k)。进而，第一UE根据其他UE在T号帧之前使用的频域资源位置i，以及时域资源位置(j，k)，确定自己在0号帧的时频资源信息，该时频资源信息包括第一UE的频域资源位置i_A(0)，以及时第一UE的时域资源位置(j_A(0)，k_A(0))，T≥0。Specifically, the first UE may obtain the current system frame number N by using the system broadcast of the base station, and the first UE may also listen to other UEs to send the respective frames in the 0th frame to the T-1 frame before the T number frame. The time-frequency resource information used by other UEs when broadcasting a message, that is, the frequency domain resource position i used by other UEs in the 0th frame to the T-1th frame, and the time domain resource location (j, k). Further, the first UE determines the time-frequency resource information of the frame 0 in the frame according to the frequency domain resource position i used by the other UE before the T-frame frame and the time domain resource location (j, k), where the time-frequency resource information includes The frequency domain resource location i _A (0) of the first UE, and the time domain resource location (j _A (0), k _A (0)) of the first UE, T ≥ 0.

在确定第一UE在0号帧的频域资源位置i_A(0)，以及时第一UE的时域资源位置(j_A(0)，k_A(0))之后，第一UE根据当前系统帧号T和第一UE在0号帧的频域资源位置，执行步骤202以确定第一UE在T号帧的频域资源位置i_A(T)，或者，第一UE也可以执行步骤203至204确定第一UE在T号帧的时域资源位置(j_A(T)，k_A(T))。After determining the frequency domain resource location i _A (0) of the first UE in frame 0, and the time domain resource location (j _A (0), k _A (0)) of the first UE, the first UE is based on the current The system frame number T and the first UE are in the frequency domain resource location of the frame 0, and step 202 is performed to determine the frequency domain resource location i _A (T) of the first UE in the T frame, or the first UE may perform steps. 203 to 204 determine the time domain resource location (j _A (T), k _A (T)) of the first UE in the T frame.

在步骤202中，第一UE根据当前系统帧号T和第一UE在0号帧的频域资源位置，确定第一UE在T号帧的频域资源位置i_A(T)时，可以将将第一UE在0号帧的频域资源位置i_A(0)平移c*T个子载波后的频域资源位置，确定为第一UE在T号帧的频域资源位置i_A(T)，c为大于等于0的整数，即：In step 202, the first UE determines, according to the current system frame number T and the frequency domain resource location of the first UE in frame 0, that the first UE is in the frequency domain resource location i _A (T) of the T frame, The frequency domain resource position after the first UE is translated into the frequency domain resource position i _A (0) of the frame 0 by c*T subcarriers is determined as the frequency domain resource location of the first UE in the T frame. i _A (T) , c is an integer greater than or equal to 0, namely:

i_A(T)＝i_A(0)+c*T mod m。i _A (T)=i _A (0)+c*T mod m.

可以看出，当c为0时，第一UE将第一UE在0号帧的频域资源位置i_A(0)，确定为第一UE在T号帧的频域资源位置i_A(T)。As can be seen, when c is 0, a first UE UE in the first frequency domain resource location numbers 0 to i _A (0), is determined for the first UE in the frequency domain resource location number of the frame T i _A (T ).

在步骤203中，第一UE根据当前系统帧号T和第一UE在0号帧的时频资源信息，确定第一UE在T号帧的时隙组位置j_A(T)时，第一UE可以以当前系统帧号T为参量，对第一UE在0号帧的频域资源位置i_A(0)和时域资源位置(j_A(0)，k_A(0))进行线性变换，以确定第一UE在T号帧的时隙组位置j_A(T)，以使得第一UE(终端A)在一个N帧的周期内的时域资源位置，与第二UE(终端B)的时域资源位置有N-1次相隔至少3个时隙，也就是说，j_A(T)-j_B(T)不为0。这样一来，任意两个使用不同时频资源的UE(例如A和B)在跳频周期(N个帧)中，可以尽可能的不在同一个时隙组中，那么，UE之间进行广播信息的收发时就无需预留相邻时隙间的时隙间隔，从而提高了通信速度，且提高了时频资源的利用率。In step 203, the first UE determines, according to the current system frame number T and the time-frequency resource information of the first UE in frame 0, that the first UE is in the slot group position j _A (T) of the T-frame, first The UE may perform linear transformation on the frequency domain resource location i _A (0) and the time domain resource location (j _A (0), k _A (0) of the first UE in frame 0 with the current system frame number T as a parameter. Determining, by the first UE, the slot group location j _A (T) of the T frame, such that the first UE (terminal A) has a time domain resource location within a period of one N frame, and the second UE (terminal B) The time domain resource location has N-1 times separated by at least 3 time slots, that is, j _A (T)-j _B (T) is not zero. In this way, any two UEs (eg, A and B) that use different time-frequency resources can be broadcasted between UEs in the same time slot group in the frequency hopping period (N frames). When the information is sent and received, there is no need to reserve the time slot interval between adjacent time slots, thereby improving the communication speed and improving the utilization of time-frequency resources.

示例性的，第一UE可以将第一UE在0号帧的时隙组位置j_A(0)平移L*T个时隙组后的时域资源位置，确定为第一UE在T号帧的时隙组位置j_A(T)，其中，L为第一UE在0号帧的时隙位置与第一UE在0号帧的频域资源位置共同决定的，L≥0，即：Exemplarily, the first UE may determine, by the first UE, the time domain resource position after the L*T time slot group in the slot group position j _A (0) of the frame 0, to determine that the first UE is in the T frame. The slot group position j _A (T), where L is determined by the first UE in the slot position of frame 0 and the frequency domain resource position of the first UE in frame 0, L ≥ 0, namely:

j_A(T)＝j_A(0)+L*T＝j_A(0)+(3i_A(0)+k_A(0))*T(1)mod n；j _A (T)=j _A (0)+L*T=j _A (0)+(3i _A (0)+k _A (0))*T(1) mod n;

其中，当表1中n为大于或等于3*m的素数时，上式可以使得第一UE(终端A)在一个N帧的周期内的时域资源位置，与第二UE(终端B)的时域资源位置有N-1次相隔至少3个时隙，证明如下：Wherein, when n is a prime number greater than or equal to 3*m in Table 1, the above formula may cause the first UE (terminal A) to have a time domain resource location within a period of one N frame, and the second UE (terminal B) The time domain resource location has N-1 times separated by at least 3 time slots, as evidenced by:

j_A(T)＝j_A(0)+(3i_A(0)+k_A(0))*T mod n；j _A (T)=j _A (0)+(3i _A (0)+k _A (0))*T mod n;

j_B(T)＝j_B(0)+(3i_B(0)+k_B(0))*T mod n；j _B (T)=j _B (0)+(3i _B (0)+k _B (0))*T mod n;

假设k_A(0)≤k_B(0)，Suppose k _A (0) ≤ k _B (0),

1)当k_A(0)＝k_B(0)时：1) When k _A (0) = k _B (0):

j_A(T)-j_B(T)＝j_A(0)+(3i_A(0)+k_A(0))*T-j_B(0)+(3i_B (0)+k_B(0))*Tj _A (T)-j _B (T)=j _A (0)+(3i _A (0)+k _A (0))*Tj _B (0)+(3i _B (0)+k _B (0) )*T

＝j_A(0)-j_B(0)+3(i_A(0)-i_B(0))*T mod n=j _A (0)-j _B (0)+3(i _A (0)-i _B (0))*T mod n

如果i_A(0)＝i_B(0)，由于终端A与终端B使用的是不同的时频资源，因此，j_A(0)不等于j_B(0)，因此，j_A(T)-j_B(T)不为0，所以，终端A与终端B在一个周期内任意T号帧的时隙组位置至少相隔3个时隙。If i _A (0)=i _B (0), since terminal A and terminal B use different time-frequency resources, j _A (0) is not equal to j _B (0), therefore, j _A (T) -j _B (T) is not 0. Therefore, terminal A and terminal B are separated by at least three time slots in the slot group position of any T frame in one cycle.

如果i_A(0)不等于i_B(0)，那么，只有在j_A(0)-j_B(0)+3(i_A(0)-i_B(0))*T为0时，终端A与终端B在T号帧的时隙组位置相同，由于n为大于或等于3*m的素数，因此，等式j_A(0)-j_B(0)+3(i_A(0)-i_B(0))*T＝0在一个N帧的周期内只有一个解，即有N-1次j_A(T)-j_B(T)不为0的情况。If i _A (0) is not equal to i _B (0), then only when j _A (0)-j _B (0)+3(i _A (0)-i _B (0))*T is 0, Terminal A and terminal B have the same slot group position in the T frame. Since n is a prime number greater than or equal to 3*m, the equation j _A (0)-j _B (0)+3 (i _A (0) ) -i _B (0)) * T = 0 has only one solution in the period of one N frame, that is, there are cases where N-1 times j _A (T) - j _B (T) is not 0.

2)当k_A(0)不等于k_B(0)时，可以分为两种情况，即：k_A(0)与k_B(0)相差为1或者k_A(0)与k_B(0)相差为2。2) When k _A (0) is not equal to k _B (0), it can be divided into two cases, that is, k _A (0) differs from k _B (0) by 1 or k _A (0) and k _B ( 0) The phase difference is 2.

具体的，当k_A(0)与k_B(0)相差为1时，即：k_A(0)＝0，k_B(0)＝1；或者，k_A(0)＝1，k_B(0)＝2。Specifically, when k _A (0) and k _B (0) differ by 1, that is, k _A (0) = 0, k _B (0) = 1; or, k _A (0) = 1, k _B (0) = 2.

此时，只有当j_A(T)-j_B(T)＝0时，终端A与终端B在T号帧的时隙组位置相同，终端A与终端B的时隙位置才会相邻。At this time, only when j _A (T)-j _B (T)=0, the terminal group and the terminal B have the same slot group position in the T frame, and the slot positions of the terminal A and the terminal B are adjacent.

j_A(T)-j_B(T)＝j_A(0)-j_B(0)+(3(i_A(0)-i_B(0))-1)*T mod nj _A (T)-j _B (T)=j _A (0)-j _B (0)+(3(i _A (0)-i _B (0))-1)*T mod n

由于n为大于或等于3*m的素数，因此，上式在一个N帧的周期内，只有1次j_A(T)-j_B(T)为0的情况，因此，在一个N帧的周期内，有N-1次终端A与终端B的时隙位置不相邻的情况。Since n is a prime number greater than or equal to 3*m, the above equation has only one time j _A (T)-j _B (T) is 0 in the period of one N frame, and therefore, in an N frame During the period, there are cases where the slot positions of the terminal A and the terminal B are not adjacent to N-1 times.

当k_A(0)与k_B(0)相差为2时，即：k_A(0)＝0，k_B(0)＝2，此时，只有当j_A(T)-j_B(T)＝1时，终端A与终端B在T号帧的时隙位置才会相邻。When k _A (0) differs from k _B (0) by 2, ie: k _A (0) = 0, k _B (0) = 2, at this time, only when j _A (T) - j _B (T When =1, terminal A and terminal B are adjacent to each other in the slot position of the T frame.

j_A(T)-j_B(T)＝j_A(0)-j_B(0)+(3(i_A(0)-i_B(0))-2)*T mod nj _A (T)-j _B (T)=j _A (0)-j _B (0)+(3(i _A (0)-i _B (0))-2)*T mod n

由于n为大于或等于3*m的素数，因此，上式在一个N帧的周期内，只有1次j_A(T)-j_B(T)为1的情况，因此，在一个N帧的周期内，有N-1次终端A与终端B的时隙位置不相邻的情况。Since n is a prime number greater than or equal to 3*m, the above equation has only one time j _A (T)-j _B (T) is 1 in the period of one N frame, and therefore, in an N frame During the period, there are cases where the slot positions of the terminal A and the terminal B are not adjacent to N-1 times.

综上，第一UE根据(1)式可以确定第一UE在T号帧的时隙组位置j_A(T)，且保证在一个N帧的周期内，第一UE(终端A)的时域资源位置与第二UE(终端B)的时域资源位置有N-1次相隔至少3个时隙。In summary, the first UE may determine the slot group position j _A (T) of the first UE in the T frame according to the formula (1), and ensure that the time of the first UE (terminal A) is within a period of one N frame. The domain resource location is separated from the time domain resource location of the second UE (terminal B) by at least 3 slots N-1 times.

在步骤204中，第一UE在确定第一UE在T号帧的时隙位置k_A(T)时，可以将第一UE在0号帧的时隙位置k_A(0)确定为第一UE在T号帧的时隙位置k_A(T)，即：In step 204, when the first UE determines that the first UE is in the slot position k _A (T) of the T frame, the first UE may determine the slot position k _A (0) of the No. 0 frame as the first. The slot position k _A (T) of the UE in the T frame, ie:

k_A(T)＝k_A(0)。k _A (T) = k _A (0).

在步骤205中，当第一UE执行完上述步骤201至204后，可以确定第一UE在T号帧的频域资源位置i_A(T)、时隙组位置j_A(T)以及时隙位置k_A(T)，那么，第一UE便可以获取频域资源位置i_A(T)、时隙组位置j_A(T)以及时隙位置k_A(T)所指示的位置的资源，并使用该资源发送第一UE的广播消息。In step 205, after the first UE performs the above steps 201 to 204, the frequency domain resource location i _A (T) of the first UE in the T frame, the slot group location j _A (T), and the time slot may be determined. Position k _A (T), then the first UE can acquire resources of the location indicated by the frequency domain resource location i _A (T), the slot group location j _A (T), and the slot location k _A (T), And using the resource to send a broadcast message of the first UE.

可以看出，若任意UE都按照上述步骤201至205的方法发送各自的广播消息，就可以保证任意两个使用不同时频资源信息的UE在发送广播消息时，在每个N帧的周期内，都有N-1次时隙位置不相邻的情况，因此，这N-1次广播消息的收发过程中都无需等待预留的时隙间隔进行数据传输，提高了UE之间的通信速率，且提高了时频资源的利用率。It can be seen that if any UE sends its own broadcast message according to the foregoing steps 201 to 205, it can be ensured that any two UEs using different time-frequency resource information are in the period of each N frame when transmitting the broadcast message. There are cases where the N-1 time slot positions are not adjacent. Therefore, in the process of transmitting and receiving the N-1 broadcast messages, there is no need to wait for the reserved time slot interval for data transmission, thereby improving the communication rate between the UEs. And improve the utilization of time-frequency resources.

示例性的，如图4所示，为当m为2，n为7，c为0时，周期为7帧的情况下，UE按照上述广播消息的传输方法进行跳频得到的跳频图案，其中f为帧号。以1号时频资源信息为例，在0号帧时i(0)＝0，j(0)＝0，k(0)＝1，在第1帧时，i(1)＝i(0)+c*1＝0；j(0)＝j(0)+(3i(0)+k(0))*1＝1；k(1)＝k(0)＝1。Exemplarily, as shown in FIG. 4, when m is 2, n is 7, c is 0, and the period is 7 frames, the frequency hopping pattern obtained by the UE according to the transmission method of the broadcast message is performed. Where f is the frame number. Taking the time-frequency resource information of No. 1 as an example, i(0)=0, j(0)=0, k(0)=1 in frame 0, i(1)=i(0) in the first frame. ) + c * 1 = 0; j (0) = j (0) + (3i (0) + k (0)) * 1 = 1; k (1) = k (0) = 1.

在一个7帧的周期内，在0号帧时1号时频资源相邻时隙的位置上的时频资源，在第1至第6帧中从来没有重复出现过，因此，这6次广播消息的收发过程中都无需等待预留的时隙间隔，就可以进行数据传输。In a 7-frame period, the time-frequency resources at the position of the adjacent time slot of the time-frequency resource at frame 0 are never repeated in the first to sixth frames. Therefore, the 6 broadcasts are repeated. During the sending and receiving of messages, there is no need to wait for the reserved slot interval. Data transfer.

本发明的实施例提供一种广播消息的传输方法，通过将时域资源位置划分为时隙组位置和时隙位置，这样一来，第一UE便可根据在0号帧的隙组位置和时隙位置，确定第一UE在T号帧的时隙组位置和时隙位置，那么，在一个N帧的周期内，第一UE的时域资源位置与第二UE的时域资源位置有N-1次相隔至少3个时隙，也就是说，在N-1帧中，任意两个使用不同时频资源的UE的时域资源位置都至少间隔3个时隙，由于只有时隙相邻的UE进行广播消息收发时才需要等待时隙间隔，所以本发明中任意两个使用不同时频资源的UE在收发广播消息时，均无需等待预留的时隙间隔就可以进行广播消息的收发操作，解决了现有技术中UE进行跳频时由于预留时隙间隔所造成的通信速度下降以及时频资源浪费的问题。An embodiment of the present invention provides a method for transmitting a broadcast message, by dividing a time domain resource location into a slot group location and a slot location, so that the first UE can be based on the slot group position in frame 0 and The slot position determines the slot group position and the slot position of the first UE in the T frame. Then, in a period of one N frame, the time domain resource location of the first UE and the time domain resource location of the second UE are N-1 times are separated by at least 3 time slots, that is, in the N-1 frame, the time domain resource positions of any two UEs using different time-frequency resources are separated by at least 3 time slots, since only the time slot phase The neighboring UEs need to wait for the time slot interval when performing broadcast message transmission. Therefore, any two UEs using different time-frequency resources in the present invention can broadcast messages without waiting for the reserved time slot interval. The transceiver operation solves the problem that the communication speed is reduced and the time-frequency resource is wasted due to the reserved slot interval when the UE performs frequency hopping in the prior art.
