Description

一种时间提前量 TA值的指示方法及装置技术领域 Method and device for indicating time advance TA value

本发明涉及通信技术领域，特别涉及一种 TA值的指示方法及装置。背景技术 The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for indicating a TA value. Background technique

GSM ( Global System for Mobile Communications, 全球移动通信系统）经过长期的发展，其技术成熟度和网络覆盖能力都非常强，因此，在通信技术领域成为关键技术之一。 GSM (Global System for Mobile Communications) has developed over the long term, and its technology maturity and network coverage are very strong. Therefore, it has become one of the key technologies in the field of communication technology.

在 GSM中，由于 GSM的小区半径可以达到 35KM,距离 BS( Base Station, 基站）较远的 MS ( Mobile Station, 移动台）向 BS发送的信号，存在电波传输延迟，需要经过一定时间才能到达 BS的问题，而时延过长会导致这样一种情况： BS接收到的 MS发送的信号的时隙，与 MS发送信号的时隙不对应，例如， BS在第二时隙才能收到 MS在第一时隙上发送的信号，导致 MS发送的信号与 BS接收的信号所在的时隙不同步，因此，为了补偿电波传输延迟，保证 BS与 MS的信号同步（即 MS在第一时隙上发送信号， BS在第一时隙上接收到该信号），需要 MS提前发送信号，提前的量为 TA ( Time Advance, 时间提前量）。 In GSM, since the cell radius of GSM can reach 35KM, the signal transmitted from the MS (Mobile Station) far away from the BS (Base Station) to the BS has a radio wave transmission delay, and it takes a certain time to reach the BS. The problem, and the delay is too long, may result in a situation in which the time slot of the signal transmitted by the MS received by the BS does not correspond to the time slot in which the MS transmits the signal. For example, the BS can receive the MS in the second time slot. The signal transmitted on the first time slot causes the signal transmitted by the MS to be out of synchronization with the time slot in which the signal received by the BS is located. Therefore, in order to compensate the radio wave transmission delay, the signal of the BS and the MS is synchronized (ie, the MS is on the first time slot). Sending a signal, the BS receives the signal on the first time slot), and the MS needs to send the signal in advance, and the amount of advance is TA (Time Advance).

现有技术中， MS确定 TA值的方法如下： In the prior art, the method for determining the TA value by the MS is as follows:

步骤 A: MS在 BS分配给该 MS的 TAI( Timing Advance Index, 时间提前量索引）对应的 PTCCH/U ( ( PTCCH Uplink, 分组时间提前量控制信道上行； PTCCH ( Packet Timing advance control channel , 分组时间提前量控制信道））上，周期性的发送 AB ( Access Burst, 接入突发脉冲）； Step A: The PTCCH/U corresponding to the TAI (Timing Advance Index) assigned by the MS to the MS in the BS ((PTCCH Uplink, Packet Timing advance control channel uplink; PTCCH (Packet Timing advance control channel) On the advance control channel)), periodically send AB (Access Burst, access burst);

其中， PTCCH的结构如图 1A所示。 The structure of the PTCCH is as shown in Fig. 1A.

步骤 B: BS根据接收到的 AB计算出该 MS的 TA值； Step B: The BS calculates the TA value of the MS according to the received AB;

步骤 C: BS将计算出的 TA值携带在 TA message (消息）中发送至 MS; 其中， TA消息以 NB ( Normal Burst, 普通突发脉冲）形式发送， NB的结构如图 1B所示。 Step C: The BS carries the calculated TA value in a TA message (message) and sends it to the MS; The TA message is sent in the form of NB (Normal Burst), and the structure of the NB is as shown in FIG. 1B.

例如， MS在 TAI=0的位置发送 AB, 则 MS最快可在 TA message 2中获得更新的 TA值， TA message的结构如图 1C所示， TA message 2是一种具体的 TA message , TA message 1、 TA message 2、 TA message 3等等各个 TA message 的结构相同，只不过发送的时间及携带的内容不同。 For example, if the MS sends AB at the position of TAI=0, the MS can obtain the updated TA value in TA message 2 as soon as possible. The structure of the TA message is as shown in FIG. 1C, and TA message 2 is a specific TA message, TA. Message 1, TA message 2, TA message 3, etc. The structure of each TA message is the same, except that the time of transmission and the content carried are different.

步骤 D: MS解析出接收到的在 TA message中携带的与该 MS相对应的 TA值，并根据该 TA值向 BS发送信号。 Step D: The MS parses out the received TA value corresponding to the MS carried in the TA message, and sends a signal to the BS according to the TA value.

在该步骤中， TA message的 octetl-16 中的每个 octet对应一个 TAI, 也对应了在该 TAI所对应的 PTCCH/U发送信号的 MS , 则该 octet中携带的 TA 值就为该 MS对应的 TA值。 In this step, each octet in the octetl-16 of the TA message corresponds to a TAI, and corresponds to the MS that sends the signal to the PTCCH/U corresponding to the TAI, and the TA value carried in the octet is the MS corresponding to the MS. TA value.

目前，为了提高解码的准确度， BS在信道建立时会给 MS分配在该信道上釆用用于信道估计、提高解码的准确度的 TS( Training Sequence,训练序列 ), TS包含在 NB的结构中，如图 1B所示。 At present, in order to improve the accuracy of decoding, the BS allocates a TS (Training Sequence) for the channel estimation and the accuracy of decoding on the channel when the channel is established, and the TS is included in the structure of the NB. Medium, as shown in Figure 1B.

为了提升容量，在同一物理信道上复用多个 MS, 其中，多个 MS对应不同的 TS, 即使 TAmessage中携带了多个 MS对应的 TA值，但只有 MS在确定分配的 TS与 BS发送 TAmessage所釆用的 TS相同时，才能解析出 TA message中携带的与该 MS对应的 TA值，其他 MS则不能解析出 TA message 中携带的对应的 TA值。发明内容 In order to increase the capacity, multiple MSs are multiplexed on the same physical channel, where multiple MSs correspond to different TSs. Even if the TAmessage carries the TA values corresponding to multiple MSs, only the MS determines the allocated TS and the BS sends the TAmessage. When the used TS is the same, the TA value corresponding to the MS carried in the TA message can be parsed, and the other MSs cannot parse the corresponding TA value carried in the TA message. Summary of the invention

The beneficial effects of the present invention are as follows:

现有技术中，当同一 PTCCH上复用多个 MS时，在发送携带各个终端分别相对应的 TA值的 TA message时，虽然要多次发送 TA message , 由于只釆用一种 TS发送 TA message , 因此，即使 TA message中携带了多个 MS对应的 TA值，但是，只有被分配的 TS与 BS发送 TA message所釆用的 TS相同时， MS才能解析出 TA message中携带的与该 MS对应的 TA值，其他被分配的 TS与 BS发送 TA message所釆用的 TS不相同的 MS, 则不能解析出 TA message中携带的对应的 TA值，因此，存在有些 MS无法获取 TA值的问题，而本发明实施例中，在发送携带 TA值的消息时，分别釆用各个 MS分别对应的 TS进行发送，这样，就保证了该 PTCCH上的每一个终端均可以从接收到的消息中解析出消息中携带的与本终端相对应的 TA值，从而，避免了现有技术中当同一 PTCCH上存在多个 MS时，存在 MS无法获取 TA值的问题。附图说明 In the prior art, when multiple MSs are multiplexed on the same PTCCH, when transmitting a TA message carrying a TA value corresponding to each terminal, although a TA message is to be transmitted multiple times, only one TS is used to send a TA message. Therefore, even if the TA message carries the TA value corresponding to the multiple MSs, the MS can parse the TA message corresponding to the MS if the allocated TS is the same as the TS used by the BS to send the TA message. The value of the TA, the other allocated TS is not the same as the TS used by the BS to send the TA message, and the corresponding TA value carried in the TA message cannot be parsed. Therefore, there are some problems that the MS cannot obtain the TA value. In the embodiment of the present invention, when the message carrying the TA value is sent, the TS corresponding to each MS is separately sent, so that each terminal on the PTCCH can be parsed from the received message. The TA value corresponding to the terminal carried in the message, thereby avoiding the problem that the MS cannot obtain the TA value when there are multiple MSs on the same PTCCH in the prior art. .

或者，也可以是，在发送如图 1A中的消息 2时可以釆用 TS1 , 消息 2中至少携带第一终端 A的 TA, 此时，消息 2为第一消息；发送 TA消息 3时可以釆用 TS2, 消息 3中至少携带第二终端 B的 TA,此时，消息 3为第二消息；发送消息 4时可以釆用 TS3 , 消息 4中至少携带第三终端 C的 TA, 此时，消息 4为第三消息；在下一个第一终端 A的 TA更新周期发送消息 1时可以釆用 TS1 , 消息 1中至少携带第一终端 A的 TA, 此时，消息 1为第一消息；发送消息 2时可以釆用 TS1 , 消息 2中至少携带第一终端 A的 TA, 此时，消息 2也为第一消息；发送消息 3时可以釆用 TS2, 消息 3中至少携带第二终端 B 的 TA, 此时，消息 3为第二消息；发送消息 4时可以釆用 TS3 , 消息 4中至少携带第三终端 C的 TA, 此时，消息 4为第三消息；依次类推，具体如图 4D所示，其中，图 4D中的 MS可以是第一终端 A、第二终端8、第三终端 C 中的任意一种。 Alternatively, TS1 may be used when sending message 2 as shown in FIG. 1A, and message 2 carries at least the TA of the first terminal A.

可选地，上述步骤 320中，当第一消息与第二消息相同时，釆用第一 TS 在该同一 PTCCH上发送第一消息，釆用第二 TS在该同一 PTCCH上发送第二消息，可以包括： Optionally, in the foregoing step 320, when the first message is the same as the second message, the first TS sends the first message on the same PTCCH, and the second TS sends the second message on the same PTCCH. Can include:

釆用第一 TS在该同一 PTCCH上发送 N次第一消息； Sending the first message N times on the same PTCCH by using the first TS;

釆用第二 TS在该同一 PTCCH上发送 N次第二消息； Transmitting, by the second TS, N times of the second message on the same PTCCH;

其中， N为正整数。 Where N is a positive integer.

例如，第一终端对应第一 TS,第二终端对应第二 TS,若在指定时间段内，共发送了 10次消息，在这 10次发送消息的过程中，要至少釆用一次第一 TS, 也要至少釆用一次第二 TS。 For example, the first terminal corresponds to the first TS, and the second terminal corresponds to the second TS. If a message is sent 10 times in a specified time period, the first TS is used at least once during the 10 times of sending the message. , also use the second TS at least once.

需要说明的是，上述第一消息、第二消息可以为 TA消息，此处不做限定。本发明实施例中，为在同一 PTCCH上的第一终端与第二终端分别分配第一 TS、第二 TS; 确定第一终端的 TA与第二终端的 TA; 釆用第一 TS在该同一 PTCCH上发送第一消息，釆用第二 TS在该同一 PTCCH上发送第二消息，使得该 PTCCH上的每一个终端均可以从接收到的消息中解析出消息中携带的与本终端的 TA值，解决了现有技术中当同一 PTCCH上存在多个 MS时，存在 MS无法获取 TA值的问题。 It should be noted that the foregoing first message and the second message may be TA messages, which are not limited herein. In the embodiment of the present invention, the first terminal and the second terminal on the same PTCCH are respectively allocated the first a TS, a second TS; determining a TA of the first terminal and a TA of the second terminal; using the first TS to send the first message on the same PTCCH, and using the second TS to send the second message on the same PTCCH, Therefore, each terminal on the PTCCH can parse the TA value of the terminal and the current value carried in the message from the received message, which solves the problem that the MS cannot obtain the TA when there are multiple MSs on the same PTCCH in the prior art. The value of the problem.

可选地，本发明实施例的一种实施场景下，在步骤 310的确定第一终端的 TA、第二终端的 TA之前，还包括： Optionally, in an implementation scenario of the embodiment of the present invention, before determining the TA of the first terminal and the TA of the second terminal in step 310, the method further includes:

为第一终端和第二终端分别分配第一 TAI和第二 TAI Assigning the first TAI and the second TAI to the first terminal and the second terminal respectively

其中， TAI组的划分方式有多种，可选的，第一 TAI组包括承载第三消息的所有下行帧分别对应的 TAI, 其中，第三消息为第一 TAI对应的下行帧承载的消息； The TAI group is divided into multiple types. Optionally, the first TAI group includes a TAI corresponding to all downlink frames that carry the third message, where the third message is a message carried by the downlink frame corresponding to the first TAI.

第二 TAI组包括承载第四消息的所有下行帧分别对应的 TAI, 其中，第四消息为第二 TAI对应的下行帧承载的消息。 The second TAI group includes a TAI corresponding to all downlink frames carrying the fourth message, where the fourth message is a message carried by the downlink frame corresponding to the second TAI.

例如，如图 1A所示， TAI=0 /1/2/3 分别对应的 PTCCH/U分别对应的 PTCCH/D共同承载 TA message 1 ,则 TAI=0 /1/2/3属于同一 TAI组； TAI=4/5/6/7 分别对应的 PTCCH/U 分别对应的 PTCCH/D 共同承载 TA message2 , 则 TAI=4/5/6/7属于同一 TAI组； ΤΑΙ=8/9/10/11分别对应的 PTCCH/U分别对应的 PTCCH/D共同承载 TA message3 , 则 ΤΑΙ=8/9/10/11 属于同一 TAI组； TAI=12/13/14/15 分别对应的 PTCCH/U分别对应的 PTCCH/D共同承载 TA message4, 则 TAI=12/13/14/15属于同一 TAI组。 For example, as shown in FIG. 1A, PTCCH/D corresponding to PTCCH/U corresponding to TAI=0/1/2/3 respectively carries TA message 1 , and TAI=0 /1/2/3 belongs to the same TAI group; TAI=4/5/6/7 PTCCH/D corresponding to PTCCH/U respectively carry TA message2, then TAI=4/5/6/7 belongs to the same TAI group; ΤΑΙ=8/9/10/11 PTCCH/D corresponding to each PTCCH/U respectively carries TA message3, then ΤΑΙ=8/9/10/11 belongs to the same TAI group; TAI=12/13/14/15 corresponds to PTCCH/U respectively PTCCH/D jointly carries TA message4, then TAI=12/13/14/15 belongs to the same TAI group.

具体地， TAI 对应的是 PTCCH/U, TA 消息是由 PTCCH/D ( PTCCH Downlink, 分组时间提前量控制信道下行）承载的，具体为： 4个下行 TDMA ( Time Division Multiple Access, 时分复用接入）帧构成一个 PTCCH/D, 承载一个 TA消息，也就是说， 4个 TAI值对应的 PTCCH/U对应的 PTCCH/D 共同承载一个 TA消息，其中，这 4个 TAI值属于同一 TAI组。需要指出的是，在本发明实施例中， TAI与上行帧对应，上行帧再与下行帧对应，也就是说，通过上行帧， TAI间接与下行帧对应起来，上述提及的下行帧分别对应的 TAI, 实际上是，下行帧分别对应的上行帧分别对应的 TAI。 Specifically, the TAI corresponds to the PTCCH/U, and the TA message is carried by the PTCCH/D (PTCCH Downlink, packet time advance control channel downlink), specifically: 4 downlink TDMA (Time Division Multiple Access, time division multiplexing) The incoming frame constitutes a PTCCH/D and carries a TA message. That is, the PTCCH/D corresponding to the PTCCH/U corresponding to the four TAI values jointly carries a TA message, wherein the four TAI values belong to the same TAI group. Need to point out In the embodiment of the present invention, the TAI corresponds to the uplink frame, and the uplink frame corresponds to the downlink frame, that is, the TAI is indirectly associated with the downlink frame by using the uplink frame, and the TAI corresponding to the downlink frame mentioned above is respectively Actually, the TAI corresponding to each of the uplink frames corresponding to the downlink frames respectively.

进一步地，步骤 320中釆用第一 TS在该同一 PTCCH上发送第一消息，釆用第二 TS在该同一 PTCCH上发送第二消息，还可以釆用如下方式： Further, in step 320, the first TS is used to send the first message on the same PTCCH, and the second TS is used to send the second message on the same PTCCH, and the following manner can also be used:

进一步的，为了提高终端更新 TA的效率，第一 TAI组的下一个 TAI组可以为第一 TAI组的相邻的下一个 TAI组；第二 TAI组的下一个 TAI组可以为第二 TAI组的相邻的下一个 TAI组。 Further, in order to improve the efficiency of the terminal updating the TA, the next TAI group of the first TAI group may be the adjacent next TAI group of the first TAI group; the next TAI group of the second TAI group may be the second TAI group. Adjacent to the next TAI group.

其中，若第二 T AI组中的所有 T AI中的最大值小于第二终端的 T A更新周期中的所有 TAI中的最大值，则第二 TAI组的相邻的下一个 T AI组为比第二 TAI组中的所有 TAI中的最大值大于 1的 TAI所属的 TAI组，且第二 TAI 组的相邻的下一个 TAI组中的所有 TAI均大于第二 TAI组中的所有 TAI中的最大值；若第二 TAI组中的所有 TAI中的最大值等于第二终端的 TA更新周期中的所有 TAI中的最大值，则第二 TAI组的相邻的下一个 TAI组为第二终端的 TA更新周期的相邻下一个 TA更新周期中所有 TAI中的最小 TAI所属的 TAI组。 Wherein, if the maximum value of all T AIs in the second T AI group is smaller than the maximum value of all TAIs in the TA update period of the second terminal, the adjacent next T AI group of the second TAI group is a ratio The maximum of all TAIs in the second TAI group is greater than the TAI group to which the TAI belongs, and all TAIs in the adjacent next TAI group of the second TAI group are greater than all TAIs in the second TAI group. Maximum value; if the maximum value of all TAIs in the second TAI group is equal to the maximum value of all TAIs in the TA update period of the second terminal, the adjacent next TAI group of the second TAI group is the second end The TAI group to which the smallest TAI of all TAIs in the adjacent TA update period of the end TA update period belongs.

具体地，第一终端的 TA更新周期可以是第一终端的两次 TA更新之间的间隔，例如，如图 4E所示，由于 4个 TA可以同时包含在一条消息中发送给终端，则若第一终端的 TAI为 0至 3中任一值时，第一终端的 TA更新周期包括 TAI=0所在的 52复帧至 TAI=15所在的 52复帧；若第二终端的 TAI 为 4至 7中任一值时，则第二终端的 TA更新周期包括 TAI=4所在的 52复帧至 TAI=15所在 52复帧，还包括与该 TAI=15所在 52复帧紧邻的 TAI=0所在复帧至 TAI=3所在 52复帧。终端在自身的每一个对应的 TA更新周期都要发送一次 AB, 进而 BS每一个 TA更新周期都会接收到与该周期对应的终端发送的 AB, 对于每一个终端的 TA更新周期，只不过接收到的 AB对应的 TA可能不相同，同理，对于每一个终端的 TA更新周期， BS在对应的子帧上都会发送一次对应的消息，只不过消息携带的内容可能不同（即 TA值可能不同）。 Specifically, the TA update period of the first terminal may be an interval between two TA updates of the first terminal, for example, as shown in FIG. 4E, since four TAs can be simultaneously included in one message and sent to the terminal, When the TAI of the first terminal is any value from 0 to 3, the TA update period of the first terminal includes 52 multiframes where TAI=0 is located to 52 multiframes where TAI=15; if the TAI of the second terminal is 4 to In any of the values of 7, the TA update period of the second terminal includes 52 multiframes where TAI=4 is located to 52 multiframes where TAI=15 is located, and TAI=0 is immediately adjacent to the 52 multiframes where the TAI=15 is located. Multiframe to 52 multiframe where TAI=3. The terminal sends AB once in each corresponding TA update period of its own, and then the BS receives the AB sent by the terminal corresponding to the period in each TA update period, and only receives the TA update period for each terminal. The TA corresponding to the AB may be different. Similarly, for each terminal's TA update period, the BS will send a corresponding message once in the corresponding subframe, but the content carried by the message may be different (that is, the TA value may be different) .

例如，如图 4E所示，假设 TAI=0,1,2,...,15, 共 15个 TAI, 基站该所有 TAI分成四组，其中， TAI=0、 TAI=1、 TAI=2、 TAI=3属于第一 TAI组，该第一 TAI组中各 TAI分别对应的下行帧承载的消息为 TA message 1； TAI=4、 TAI=5、 TAI=6、 TAI=7属于第二 TAI组，该第二 TAI组中各 TAI对应的下行帧承载的消息为 TAmessage2; TAI=8、 TAI=9、 TAI=10、 TAI=11属于第三 TAI 组，该第三 TAI组中各 TAI对应的下行帧承载的消息为 TAmessage3; TAI=12、 TAI=13、 TAI=14、 TAI=15属于第四 TAI组，该第四 TAI组中各 TAI对应的下行帧承载的消息为 TAmessage4;若在同一 PTCCH上同时分配了四个终端：第一终端、第二终端、第三终端及第四终端，基站分配给该四个终端的 TAI 分别为 TAI=0、 TAI=4、 TAI=8、 TAI=12, 并为该四个终端分别分配 TS1、 TS2、 TS3、 TS4。 For example, as shown in FIG. 4E, assuming TAI=0, 1, 2, ..., 15, a total of 15 TAIs, the base station has all TAIs divided into four groups, where TAI=0, TAI=1, TAI=2. The TAI=3 belongs to the first TAI group, and the message carried by the downlink frame corresponding to each TAI in the first TAI group is TA message 1; TAI=4, TAI=5, TAI=6, and TAI=7 belong to the second TAI group. The message carried by the downlink frame corresponding to each TAI in the second TAI group is TAmessage2; TAI=8, TAI=9, TAI=10, and TAI=11 belong to the third TAI group, and each TAI in the third TAI group corresponds to The message carried by the downlink frame is TAmessage3; TAI=12, TAI=13, TAI=14, and TAI=15 belong to the fourth TAI group, and the message carried by the downlink frame corresponding to each TAI in the fourth TAI group is TAmessage4; Four terminals are simultaneously allocated on the PTCCH: the first terminal, the second terminal, the third terminal, and the fourth terminal, and the TAIs allocated by the base station to the four terminals are TAI=0, TAI=4, TAI=8, TAI= 12, and allocate TS1, TS2, TS3, and TS4 for the four terminals.

进一步地，由于第一 TAI组中的所有 TAI中的最大值 TAImaxl=3小于第一终端的 TA更新周期中的所有 TAI中的最大值 TAIm_axr=15 ,且满足比该第一 TAI组中的所有 TAI中的最大值 TAImaxl=3大于 1的 TAI所属的 TAI组，即 TAI=4所属的 TAI组为第二 TAI组，该第二 TAI组中的所有 TAI均大于第一 TAI组中的所有 TAI中的最大值 TAImaxl=3 , 则在第二 TAI组对应的下行帧上釆用 TS1发送 TAmessage2, 该 TAmessage2携带第一终端的 TA信息。 Further, since the maximum value TAImax1=3 of all the TAIs in the first TAI group is smaller than the maximum value TAIm _ax r=15 among all the TAIs in the TA update period of the first terminal, and is satisfied in the first TAI group. The maximum value of TAImaxl=3 in all TAIs is greater than 1 for the TAI group to which the TAI belongs. That is, the TAI group to which the TAI=4 belongs is the second TAI group, and all the TAIs in the second TAI group are greater than the maximum value TAImax1=3 in all the TAIs in the first TAI group, and then the downlink corresponding to the second TAI group On the frame, TA1sage2 is sent by TS1, and the TAmessage2 carries the TA information of the first terminal.

进一步地，由于第四 TAI组中的所有 TAI中的最大值 TAIma_X4=15等于第四终端的 TA更新周期中的所有 TAI中的最大值 TAIma_X4'=15 ,且满足第四终端的 TA更新周期的相邻下一个 TA更新周期中所有 TAI中的最小 TAI所属的 TAI组为该第四终端的 TA更新周期的相邻下一个 TA更新周期中的第一 TAI组，则第四终端在该第四终端的 TA更新周期的 TAI= 15对应的上行帧上发送 AB后，基站釆用 TS4在第四终端的 TA更新周期的相邻下一个 TA更新周期的第一 TAI组对应的下行帧上发送包含该第四终端的 TA值的消息，因此第四终端就可以从该第四终端的 TA更新周期的相邻的下一个 TA更新周期的 TAmessagel中解析出相应的 TA值。依次类推，釆用 TS2在第三 TAI组对应的下行帧上发送携带第二终端 TA信息的 TAmessage2, 此处不再赘述。 Further, since the maximum value TAIma _X 4=15 among all the TAIs in the fourth TAI group is equal to the maximum value TAIma _X 4'=15 among all the TAIs in the TA update period of the fourth terminal, and the fourth terminal is satisfied. The TAI group to which the smallest TAI of all the TAIs in the adjacent TA update period of the TA update period belongs to the first TAI group in the next TA update period of the TA update period of the fourth terminal, and the fourth terminal After transmitting AB on the uplink frame corresponding to TAI=15 of the TA update period of the fourth terminal, the base station uses TS4 in the downlink corresponding to the first TAI group of the next TA update period of the TA update period of the fourth terminal. A message including the TA value of the fourth terminal is transmitted on the frame, so the fourth terminal can parse the corresponding TA value from the TAmessagel of the adjacent next TA update period of the TA update period of the fourth terminal. By analogy, the TS2 sends the TAMESsage2 carrying the second terminal TA information on the downlink frame corresponding to the third TAI group, and details are not described herein again.

进一步，上述一种实施场景中，还包括：为在该同一 PTCCH上的第三终端分配第三 TAI和第三 TS。其中，第三 TAI与第一 TAI属于同一 TAI组，第三 TS与第一 TS相同。 Further, in an implementation scenario, the method further includes: allocating a third TAI and a third TS to the third terminal on the same PTCCH. The third TAI belongs to the same TAI group as the first TAI, and the third TS is the same as the first TS.

具体地，若为第三终端分配的第三 TAI所属的第三 TAI组与第一终端对应的第一 TAI所属的第一 TAI组相同时，则为第三终端分配的第三 TS就为第 — TS; 或者，若为第三终端分配的第三 TS为第一 TS, 则为第三终端分配的第三 TAI所属的第三 TAI组为第一终端对应的第一 TAI所属的第一 TAI组。 Specifically, if the third TAI group to which the third TAI allocated to the third terminal belongs is the same as the first TAI group to which the first TAI corresponding to the first terminal belongs, the third TS allocated to the third terminal is the third - TS; or, if the third TS allocated to the third terminal is the first TS, the third TAI to which the third TAI assigned to the third terminal belongs is the first TAI to which the first TAI corresponding to the first terminal belongs. group.

例如，若给第三终端分配的第三 TS与第一 TS相同，即在同一 PTCCH 增加了终端，但 TS没有增加，则在发送第三终端的 TA信息时，将该第三终端的 TA信息携带在第一消息中发送。 For example, if the third TS allocated to the third terminal is the same as the first TS, that is, the terminal is added in the same PTCCH, but the TS is not increased, the TA information of the third terminal is sent when the TA information of the third terminal is sent. Carry in the first message sent.

进一步地，若给该同一 PTCCH上的第四终端分配的 TS为除第一 TS与第二 TS之外的其他 TS时，如第四 TS时，且第四 TS与第一 TS和第二 TS 任意一个均不相同时，则在发送第四终端的 TA信息时，要釆用第四 TS发送携带有第四终端的 TA信息的消息。在上述一种实施场景中，通过对 TAI分组，且同一 TAI组中各 TAI对应的 TS相同，即分配在同一 TAI组的终端分配的 TS相同，以使得在该同一 TAI 组的终端的 TA信息可以携带在同一 TA消息中，一并发送给各终端，以及各终端的 TA更新及时性得到提高，同时节省了空口信息流量。为了更好地理解本发明实施例，以下给出具体应用场景，针对 TA值指示的过程，作出进一步详细描述（携带各个终端分别相对应的 TA值的当前待发送的消息为 TA message ): Further, if the TS allocated to the fourth terminal on the same PTCCH is another TS other than the first TS and the second TS, such as the fourth TS, and the fourth TS and the first TS and the second TS When any one of them is different, when transmitting the TA information of the fourth terminal, the fourth TS is used to send the message carrying the TA information of the fourth terminal. In the foregoing implementation scenario, the TSI is grouped, and the TSs corresponding to the TAIs in the same TAI group are the same, that is, the TSs allocated by the terminals allocated in the same TAI group are the same, so that the TA information of the terminals in the same TAI group is the same. It can be carried in the same TA message and sent to each terminal together, and the TA update timeliness of each terminal are improved, and the air interface information traffic is saved. For a better understanding of the embodiments of the present invention, a specific application scenario is given below, and a further detailed description is given for the process of indicating the TA value (the current message to be sent carrying the corresponding TA value of each terminal is a TA message):

实施例一：如图 5A所示： Embodiment 1: As shown in FIG. 5A:

步骤 500: 为同一 PTCCH上的两个终端 A、 B分别分配 TAI1、 TAI2; 例如， TAI=0,1,2,...,15, 共 16个 TAI, 为终端 A分配 ΤΑΙ1=1 , 为终端 B 分配 TAI2=8。 Step 500: Assign TAI1 and TAI2 to the two terminals A and B on the same PTCCH respectively; for example, TAI=0, 1, 2, ..., 15, a total of 16 TAIs, and allocate ΤΑΙ1=1 for terminal A, Terminal B allocates TAI2=8.

步骤 510: 为该同一 PTCCH上的两个终端 A、 B分别分配的 TS为： TS1、 Step 510: The TSs allocated for the two terminals A and B on the same PTCCH are: TS1.

TS2; TS2;

步骤 520: 接收终端 A、 B分别在该同一 PTCCH上发送的 AB, 并分别计算出终端 A、 B对应的 TA值： TAI、 TA2; Step 520: Receive the ABs sent by the terminals A and B respectively on the same PTCCH, and calculate the TA values corresponding to the terminals A and B respectively: TAI, TA2;

具体地，终端 A、 B分别在该同一 PTCCH上 TAI1=1、 TAI2=8对应的上行帧上分别发送 AB。 Specifically, the terminals A and B respectively transmit AB on the same frame corresponding to TAI1=1 and TAI2=8 on the same PTCCH.

步骤 530: 釆用 TS1发送携带有 TA1的 TA messagel , 釆用 TS2发送携带有 TA2的 TAmessage2₀ Step 530: TS1 carrying preclude transmission of TA messagel TA1, TS2 carrying preclude transmission of TA2 TAmessage2 ₀

在该步骤中， TAmessagel , TAmessage2中也可以均携带 TAI、 TA2。在本步骤中，可釆用 TS1 发送 TA messagel, 然后釆用 TS2 发送 TA message2, 再然后釆用 TS1 发送 TA messagel, 再然后釆用 TS2 发送 TA message 2,如图 5B所示，也可以是，釆用 TS1发送 TAmessagel, 再釆用 TS1 发送 TAmessagel , 然后，釆用 TS2发送 TA message2, 再然后釆用 TS2 发送 TAmessage 2,总之，就是分别釆用至少一次 TS1发送携带 TA1的 TAmessagel 和至少一次 TS2发送携带 TA2的 TAmessage2, 如图 5C所示。实施例二：如图 5D所示： In this step, TAmessagel and TAmessage2 can also carry TAI and TA2. In this step, you can use TS1 to send TA messagel, then use TS2 to send TA message2, then use TS1 to send TA messagel, and then use TS2 to send TA message 2, as shown in Figure 5B, or发送Send TAmessagel with TS1, then send TAmessagel with TS1, then send TA message2 with TS2, then send TAmessage 2 with TS2. In short, send TAmessagel carrying TA1 and at least one TS2 send at least once TS1 respectively. TAmessage2 carrying TA2, as shown in Figure 5C. Embodiment 2: As shown in FIG. 5D:

步骤 5000: 为同一 PTCCH上所包括的所有 TAI进行分组； Step 5000: Group all TAIs included on the same PTCCH;

例如，该同一 PTCCH上所包括的所有 TAI为 TAI=0,1,2,...,15, 共 16个 TAI ,分组情况如下： TAI=0、 TAI=1、 TAI=2、 TAI=3为第一 TAI组； TAI=4、 TAI=5, TAI=6, TAI=7为第二 TAI组； TAI=8, TAI=9, TAI=10, TAI=11为第三 TAI组； TAI=12、 TAI=13、 TAI=14、 TAI=15为第四 TAI组。 For example, all TAIs included on the same PTCCH are TAI=0, 1, 2, ..., 15, a total of 16 TAIs, and the grouping is as follows: TAI=0, TAI=1, TAI=2, TAI=3 It is the first TAI group; TAI=4, TAI=5, TAI=6, TAI=7 is the second TAI group; TAI=8, TAI=9, TAI=10, TAI=11 is the third TAI group; TAI= 12. TAI=13, TAI=14, and TAI=15 are the fourth TAI group.

步骤 5100: 为在该同一 PTCCH上的两个终端 A、 B分别分配第一 TAI 组中的 TAI1、第二 TAI组中 TAI2; Step 5100: Assign TAI1 in the first TAI group and TAI2 in the second TAI group to the two terminals A and B on the same PTCCH.

例如， TAI1可以为 1、 TAI2可以为 5, TAI=1、 TAI=5分别属于第一 TAI 组和第二 TAI组。 For example, TAI1 can be 1, TAI2 can be 5, TAI=1, and TAI=5 belong to the first TAI group and the second TAI group, respectively.

步骤 5200: 为在该同一 PTCCH上的两个终端 A、 B分别分配的 TS为： TS1、 TS2; Step 5200: The TSs allocated for the two terminals A and B on the same PTCCH are: TS1, TS2;

步骤 5300: 接收终端 A、 B分别发送的 AB, 并分别计算出终端 A、 B对应的 TA值： TA1、 TA2; Step 5300: Receive the ABs sent by the terminals A and B respectively, and calculate the TA values corresponding to the terminals A and B respectively: TA1, TA2;

步骤 5400: 釆用 TS1在第一 TAI组的相邻下一个 TAI组对应的下行帧上发送携带有 TA1的第一消息，釆用 TS2在第二 TAI组的相邻下一个 TAI组对应的下行帧上发送携带有 TA2的第二消息，如图 5E所示。 Step 5400: The TS1 sends the first message carrying the TA1 in the downlink frame corresponding to the next TAI group in the first TAI group, and uses the TS2 in the downlink corresponding to the next TAI group in the second TAI group. A second message carrying TA2 is transmitted on the frame, as shown in FIG. 5E.

例如，根据步骤 5000中的分组，釆用 TS1在 TAI=4,5,6,7对应的下行帧上发送第一消息，釆用 TS2在 TAI=8,9,10,11对应的下行帧上发送第二消息。 For example, according to the packet in step 5000, the first message is sent on the downlink frame corresponding to TAI=4, 5, 6, 7 by using TS1, and the TS2 is on the downlink frame corresponding to TAI=8, 9, 10, 11 Send the second message.

在本发明实施例中， TAI与上行帧对应，上行帧再与下行帧对应，也就是说，通过上行帧， TAI间接与下行帧对应起来，上述提及的 TAI分别对应的下行帧，实际上是， TAI分别对应的上行帧分别对应的下行帧。 In the embodiment of the present invention, the TAI corresponds to the uplink frame, and the uplink frame corresponds to the downlink frame, that is, the TAI is indirectly associated with the downlink frame by using the uplink frame, and the downlink frame corresponding to the TAI mentioned above is actually Yes, the downlink frames corresponding to the uplink frames corresponding to the TAI respectively.

本发明实施例中，步骤 300-步骤 320主要论述的是同一 PTCCH上存在两个不同的终端且分配不同的 TS的情况，在实际应用中，还存在同一 PTCCH 上存在两个以上不同的终端被分别分配不同的 TS的情况，但是，这种情况若分别釆用不同的 TS发送消息时，包括步骤 300-步骤 320的技术方案，因此，在此不再进行详述。在实际应用中，每次为终端分配 TAI、 TS等参数时，是基于一个连接 TBF ( Temporary Block Flow, 临时块流）进行的，而一个终端可以同时支持多个 TBF, 其中，每个 TBF可以视为一个独立的连接，因此，本申请中的终端不仅是指一个用户，也可以指上述提及的一个 TBF。 In the embodiment of the present invention, step 300-step 320 mainly discusses the case where two different terminals exist on the same PTCCH and different TSs are allocated. In actual applications, there are two or more different terminals on the same PTCCH. The case of different TSs is allocated separately. However, if the message is sent by using different TSs, the technical solution of step 300 to step 320 is included, and therefore, details are not described herein. In practical applications, each time a TAI, TS, and other parameters are allocated to a terminal, it is based on a TBF (Temporary Block Flow), and a terminal can simultaneously support multiple TBFs, where each TBF can It is regarded as an independent connection. Therefore, the terminal in this application refers not only to one user but also to one TBF mentioned above.

综上所述，本发明实施例中，为分配在同一 PTCCH上的第一终端与第二终端分别分配第一 TS、第二 TS; 确定第一终端的 TA与第二终端的 TA; 釆用第一 TS在同一 PTCCH上发送第一消息，釆用第二 TS, 在同一 PTCCH上发送第二消息，其中，第一消息至少携带第一终端的 TA、第二消息至少携带第二终端的 TA, 这样，就保证了分配在同一 PTCCH上的每一个终端均可以从接收到的消息中解析出携带的与本终端相对应的 TA值，从而避免了现有技术中当同一物理信道上存在多个 MS时，存在 MS无法获取 TA值的问题。 In the embodiment of the present invention, the first terminal and the second terminal are respectively allocated to the first terminal and the second terminal allocated on the same PTCCH; the TA of the first terminal and the TA of the second terminal are determined; The first TS sends the first message on the same PTCCH, and uses the second TS to send the second message on the same PTCCH, where the first message carries at least the TA of the first terminal, and the second message carries at least the TA of the second terminal. In this way, it is ensured that each terminal allocated on the same PTCCH can parse the carried TA value corresponding to the current terminal from the received message, thereby avoiding the existence of many existing physical channels on the same physical channel. When there are MSs, there is a problem that the MS cannot obtain the TA value.
