技术领域technical field
本发明涉及信道分配技术领域,具体涉及上行控制时隙分配方法、系统以及移动台。The present invention relates to the technical field of channel allocation, in particular to an uplink control time slot allocation method, system and mobile station.
背景技术Background technique
现有的通用分组无线业务(GPRS)、增强通用分组无线业务(EGPRS)技术中,在分组数据转发过程中移动台(MS)和网络之间会建立临时连接,即临时块流(TBF)。GPRS、EGPRS支持一个MS在一个方向上有多个TBF连接。分配给GPRS的时隙称为分组数据信道(PDCH),一个TBF可以在一个或多个PDCH上使用无线资源,也可以多个TBF同时复用在同一个PDCH上。在GPRS、EGPRS中,每一个TBF都有一个对应的分组辅助控制信道(PACCH)包括:下行PACCH和上行PACCH,该PACCH只可能映射在其对应的TBF所在的PDCH上。In the existing General Packet Radio Service (GPRS) and Enhanced General Packet Radio Service (EGPRS) technologies, a temporary connection, ie Temporary Block Flow (TBF), is established between the mobile station (MS) and the network during packet data forwarding. GPRS and EGPRS support multiple TBF connections in one direction for one MS. The time slot allocated to GPRS is called packet data channel (PDCH). One TBF can use radio resources on one or more PDCHs, and multiple TBFs can also be multiplexed on the same PDCH at the same time. In GPRS and EGPRS, each TBF has a corresponding packet-assisted control channel (PACCH) including: downlink PACCH and uplink PACCH, and the PACCH can only be mapped on the PDCH where the corresponding TBF is located.
目前,在物理层传输的数据的最小调度单元是无线块(Block),每个Block由4个时隙组成,且4个时隙分别位于4个连续的时分多址(TDMA)帧中,每个Block的传输时延都是20ms。高层数据封装到Block里传输,目前每个传输时间间隔(TTI)时长为20ms,即每个高层数据块至少有20ms的时延。为了减少传输时延,提出了RTTI技术。RTTI总体思想是:保持每个Block的大小不变,通过利用多载波或多时隙来减少TTI。其中,利用多时隙减少TTI的原理如图1所示,在图1中,块B1采用RTTI之前的技术传输,位于4个连续TDMA帧上,每帧占用1个时隙,则B1的TTI等于20ms;块B2和块B3采用RTTI技术传输,B2位于2个连续的TDMA帧上,每帧占用2个连续的时隙,则B2的TTI等于10ms;同理,B3的TTI等于5ms。At present, the smallest scheduling unit of data transmitted at the physical layer is a wireless block (Block), each Block is composed of 4 time slots, and the 4 time slots are located in 4 consecutive time division multiple access (TDMA) frames, each The transmission delay of each Block is 20ms. High-level data is encapsulated into blocks for transmission. Currently, each transmission time interval (TTI) is 20ms long, that is, each high-level data block has a delay of at least 20ms. In order to reduce the transmission delay, the RTTI technology is proposed. The general idea of RTTI is to keep the size of each Block constant and reduce TTI by using multiple carriers or multiple time slots. Among them, the principle of using multi-slots to reduce TTI is shown in Figure 1. In Figure 1, block B1 is transmitted using the technology before RTTI, located on 4 consecutive TDMA frames, each frame occupies 1 time slot, then the TTI of B1 is equal to 20ms; block B2 and block B3 are transmitted using RTTI technology, B2 is located on 2 consecutive TDMA frames, and each frame occupies 2 consecutive time slots, then the TTI of B2 is equal to 10ms; similarly, the TTI of B3 is equal to 5ms.
由于引入RTTI技术,会出现具有不同TTI的TBF同时在同一信道上传输的情况,将同时传输不同TTI的TBF的信道称为复用信道;而将只传输一种TTI的TBF的信道称为非复用信道。如图1中,PDCH0、PDCH1上同时传输10ms和20ms的TBF,则PDCH0、PDCH1为复用信道;PDCH3上仅传输20ms的TBF,PDCH6、PDCH7上仅传输10ms的TBF,则PDCH3、PDCH6、PDCH7为非复用信道。Due to the introduction of RTTI technology, there will be situations where TBFs with different TTIs are transmitted on the same channel at the same time. The channel that transmits TBFs with different TTIs at the same time is called a multiplexed channel; and the channel that transmits TBFs with only one TTI is called a non-multiplexed channel. multiplexing channels. As shown in Figure 1, PDCH0 and PDCH1 transmit 10ms and 20ms TBF at the same time, then PDCH0 and PDCH1 are multiplexed channels; PDCH3 only transmits 20ms TBF, and PDCH6 and PDCH7 transmit only 10ms TBF, then PDCH3, PDCH6, PDCH7 is a non-multiplexed channel.
采用RTTI技术时,通常采用如下方式确定TTI:When RTTI technology is used, the TTI is usually determined as follows:
1、对于某一给定MS,在同一信道上配置的TBF的TTI必须相同;在不同信道上配置的TBF的TTI可以相同,也可以不同。如图1中,PDCH4上的10ms的TBF和5ms的TBF不能属于同一MS,而应属于不同的MS。1. For a given MS, the TTIs of TBFs configured on the same channel must be the same; the TTIs of TBFs configured on different channels can be the same or different. As shown in Figure 1, the 10ms TBF and the 5ms TBF on PDCH4 cannot belong to the same MS, but should belong to different MSs.
2、对于某一给定MS,上行控制块的TTI与对应的下行TBF或控制块的TTI相同。如图2-1所示,网络侧向MS发送携带有效RRBP的下行20ms的TBF以对该TBF进行轮询时,则MS需在该下行TBF使用的时隙上发送指示是否收到该TBF的20ms的上行控制块;同理,如图2-2所示,网络对下行10ms的TBF进行轮询时,MS则需在该下行TBF使用的时隙上发送10ms的上行控制块。2. For a given MS, the TTI of the uplink control block is the same as the TTI of the corresponding downlink TBF or control block. As shown in Figure 2-1, when the network side sends a downlink 20ms TBF carrying a valid RRBP to the MS to poll the TBF, the MS needs to send a message indicating whether the TBF is received on the time slot used by the downlink TBF. 20ms uplink control block; similarly, as shown in Figure 2-2, when the network polls a downlink 10ms TBF, the MS needs to send a 10ms uplink control block in the time slot used by the downlink TBF.
但是,MS受多时隙能力的限制即:MS在一个TDMA帧传输时长内只能占有一定数目的时隙,因此,MS无法做到每个下行TBF对应的上行PACCH块都映射到对应的下行TBF或控制块所在的时隙上,此时网络侧通过在为下行TBF进行资源配置和重配置时,为MS分配上行控制时隙,此后MS在该上行控制时隙上发送上行控制块。However, the MS is limited by the multi-slot capability: the MS can only occupy a certain number of time slots within a TDMA frame transmission duration, so the MS cannot map the uplink PACCH block corresponding to each downlink TBF to the corresponding downlink TBF Or on the time slot where the control block is located. At this time, the network side allocates an uplink control time slot for the MS when performing resource configuration and reconfiguration for the downlink TBF, and then the MS sends the uplink control block on the uplink control time slot.
图3为现有的网络侧为MS分配上行控制时隙的流程图,如图3所示,其具体步骤如下:Fig. 3 is the flow chart of existing network side allocating uplink control time slot for MS, as shown in Fig. 3, and its specific steps are as follows:
步骤301:网络侧向MS发送分组下行指配/多TBF下行指配消息,该消息携带上行控制时隙的时隙号(TN),以指示MS可在该时隙号指示的时隙上发送上行控制块。Step 301: The network side sends a packet downlink assignment/multi-TBF downlink assignment message to the MS, and the message carries the time slot number (TN) of the uplink control time slot to indicate that the MS can transmit on the time slot indicated by the time slot number Uplink control block.
每个时隙具有一个时隙号(TN,Timeslot Number),以标识该时隙。Each time slot has a time slot number (TN, Timeslot Number) to identify the time slot.
步骤302:MS收到该消息后,保存该消息携带的上行控制时隙的时隙号。Step 302: After receiving the message, the MS saves the time slot number of the uplink control time slot carried in the message.
步骤303:网络侧向MS发送携带有效相关保留块周期(RRBP)的下行TBF1,以表示对下行TBF1进行轮询。Step 303: the network side sends a downlink TBF1 carrying a valid relevant reserved block period (RRBP) to the MS to indicate polling for the downlink TBF1.
步骤304:MS收到该下行TBF1后,将指示已收到该下行TBF1的确认(ACK)消息通过步骤301中网络侧为自身分配的时隙返回给网络侧。Step 304: After receiving the downlink TBF1, the MS returns an acknowledgment (ACK) message indicating that the downlink TBF1 has been received to the network side through the time slot allocated for itself by the network side in
步骤305:网络侧向MS发送携带有效RRBP的下行TBF2。Step 305: the network side sends the downlink TBF2 carrying the valid RRBP to the MS.
步骤306:MS收到该下行TBF2后,将指示已收到该下行TBF2的确认消息通过步骤301中网络侧为自身分配的时隙返回给网络侧。Step 306: After receiving the downlink TBF2, the MS returns an acknowledgment message indicating that the downlink TBF2 has been received to the network side through the time slot allocated for itself by the network side in
步骤307:网络侧确定需要重新为MS分配上行控制时隙,向MS发送分组时隙重配置/多TBF时隙重配置消息,该消息携带新的上行控制时隙的时隙号。Step 307: The network side determines that the uplink control time slot needs to be re-allocated to the MS, and sends a packet time slot reconfiguration/multi-TBF time slot reconfiguration message to the MS, and the message carries the time slot number of the new uplink control time slot.
步骤308:MS收到该消息后,保存该消息携带的新的上行控制时隙的时隙号。Step 308: After receiving the message, the MS saves the time slot number of the new uplink control time slot carried in the message.
步骤309:网络侧向MS发送携带有效RRBP的下行TBF1。Step 309: the network side sends the downlink TBF1 carrying the valid RRBP to the MS.
步骤310:MS收到该下行TBF1后,将指示已收到该下行TBF1的确认消息通过步骤307中网络侧为自身分配的新时隙返回给网络侧。Step 310: After receiving the downlink TBF1, the MS returns an acknowledgment message indicating that the downlink TBF1 has been received to the network side through the new time slot allocated for itself by the network side in
步骤311:网络侧向MS发送携带有效RRBP的下行TBF2。Step 311: the network side sends the downlink TBF2 carrying the valid RRBP to the MS.
步骤312:MS收到该下行TBF2后,将指示已收到该下行TBF2的确认消息通过步骤307中网络侧为自身分配的新时隙返回给网络侧。Step 312: After receiving the downlink TBF2, the MS returns an acknowledgment message indicating that the downlink TBF2 has been received to the network side through the new time slot allocated for itself by the network side in
现有技术的缺点如下:The shortcoming of prior art is as follows:
网络侧在为MS分配上行控制时隙时,该上行控制时隙仅指示1个时隙,而不指示在该时隙上发送上行控制块时所使用的TTI。而网络侧在为MS分配时隙时,有时会将两个时隙以时隙对的形式分配给MS,此后网络侧默认为该时隙对中的两个时隙总是成对使用的。而在网络侧为MS分配的上行控制时隙为时隙对中的一个时隙时,MS却无法确定是在该时隙上发送一个具有较大TTI的上行控制块、还是在包含该时隙的时隙对上发送一个具有较小TTI的上行控制块,这样可能会造成网络资源浪费。When the network side allocates an uplink control time slot to the MS, the uplink control time slot only indicates one time slot, but does not indicate the TTI used when sending the uplink control block on the time slot. When the network side allocates time slots to the MS, sometimes two time slots are allocated to the MS in the form of a time slot pair, and then the network side assumes that the two time slots in the time slot pair are always used in pairs by default. However, when the uplink control time slot allocated to the MS by the network is a time slot in a time slot pair, the MS cannot determine whether to send an uplink control block with a larger TTI on this time slot or whether to send an uplink control block containing this time slot. An uplink control block with a smaller TTI is sent on the time slot pair, which may cause waste of network resources.
如图4所示,网络侧为MS分配下行20ms TBF1和10ms TBF2,由于受MS多时隙能力限制,MS无法在下行TBF1对应的上行时隙TN1上发送与TBF1对应的上行控制块,此时,网络侧为下行TBF1分配的上行控制时隙为时隙对:TN2和TN3中的TN2。当网络侧在下行TBF1中设置RRBP进行轮询时,MS无法确定是在TN2上采用与下行TBF1的TTI一致的TTI,向网络侧反馈20ms的确认/不确认(ACK/NACK)消息,还是在TN2和TN3构成的时隙对上向网络侧反馈10ms的ACK/NACK消息,当MS选择在TN2上向网络侧反馈20ms的ACK/NACK消息时,网络侧并不知TN3未被占用,因此不会再将TN3分配给其它MS使用,这样就造成了信道资源浪费。As shown in Figure 4, the network side allocates downlink 20ms TBF1 and 10ms TBF2 to the MS. Due to the limitation of MS multi-slot capability, the MS cannot send the uplink control block corresponding to TBF1 on the uplink time slot TN1 corresponding to downlink TBF1. At this time, The uplink control time slot allocated by the network side to the downlink TBF1 is a time slot pair: TN2 in TN2 and TN3. When the network side sets the RRBP in the downlink TBF1 for polling, the MS cannot determine whether to use the TTI consistent with the TTI of the downlink TBF1 on TN2 to feed back a 20ms acknowledgment/non-acknowledgement (ACK/NACK) message to the network side, or The time slot pair formed by TN2 and TN3 feeds back a 10ms ACK/NACK message to the network side. When the MS chooses to feed back a 20ms ACK/NACK message to the network side on TN2, the network side does not know that TN3 is not occupied, so it will not The TN3 is then allocated to other MSs, which causes a waste of channel resources.

步骤501:网络侧向MS发送包含下行TBF配置信息的相关消息,该消息携带上行控制时隙标识,同时携带该上行控制时隙的TTI指示信息。Step 501: The network side sends a relevant message including downlink TBF configuration information to the MS, and the message carries an uplink control time slot identifier and TTI indication information of the uplink control time slot.
这里,包含下行TBF配置信息的相关消息包括:下行TBF配置消息、下行TBF资源重配置消息、分组电路交换释放指示消息、分组切换命令、双传输模式切换命令等。Here, related messages containing downlink TBF configuration information include: downlink TBF configuration message, downlink TBF resource reconfiguration message, packet circuit switching release indication message, packet switching command, dual transmission mode switching command, etc.
TTI指示信息用于指示MS在网络侧分配的上行控制时隙上发送上行控制块时应使用的TTI。具体地,可将包含下行TBF配置信息的相关消息的一个空闲比特作为TTI指示比特。如表1所示:当该比特为0时,表示TTI为10ms;当该比特为1时,表示TTI为20ms。The TTI indication information is used to indicate the TTI that the MS should use when sending the uplink control block on the uplink control time slot allocated by the network side. Specifically, a spare bit of a related message including downlink TBF configuration information may be used as a TTI indication bit. As shown in Table 1: when this bit is 0, it means that the TTI is 10ms; when this bit is 1, it means that the TTI is 20ms.
表1本发明实施例一提供的TTI指示设置Table 1 TTI indication setting provided by
步骤502:MS收到包含下行TBF配置信息的相关消息,判断该消息是否携带上行控制时隙标识,若是,执行步骤503;否则,执行步骤505。Step 502: The MS receives a related message containing downlink TBF configuration information, and judges whether the message carries an uplink control time slot identifier, and if so, executes
步骤503:MS确定该消息中携带的TTI指示信息对应的TTI。Step 503: The MS determines the TTI corresponding to the TTI indication information carried in the message.
步骤504:MS采用步骤503中确定的TTI,在上行控制时隙标识对应的时隙上发送上行控制块,本流程结束。Step 504: The MS uses the TTI determined in
步骤505:MS采用下行TBF的TTI,在下行TBF使用的时隙上发送上行控制块。Step 505: The MS uses the TTI of the downlink TBF to send the uplink control block on the time slot used by the downlink TBF.
由于网络侧向MS发送的包含下行TBF配置信息的相关消息只能携带一个上行控制时隙标识,而有些情况下,MS需要通过一对时隙向网络侧发送上行控制块,此时网络侧和MS必须预先协商好通过该时隙对发送上行控制块的时刻,以避免信道资源浪费。例如:网络侧对20ms的TBF设置RRBP以进行轮询,此时,网络侧为MS分配的上行控制时隙的TTI为10ms,分配的上行控制时隙为时隙对:TN2和TN3中的TN2,此时,网络侧和MS必须预先确定好MS应该是在RRBP指示的发送时刻之后的0~10ms内在TN2和TN3上发送上行控制块、还是在RRBP指示的发送时刻之后的10~20ms内在TN2和TN3上发送上行控制块。在实际应用中,根据网络侧为MS分配的上行控制时隙标识,可有以下几种确定上行控制块的发送时刻的方法:Since the relevant message containing downlink TBF configuration information sent by the network to the MS can only carry one uplink control time slot identifier, and in some cases, the MS needs to send an uplink control block to the network through a pair of time slots. The MS must pre-negotiate the time to send the uplink control block through the time slot pair to avoid wasting channel resources. For example: the network side sets RRBP for TBF of 20ms for polling. At this time, the TTI of the uplink control time slot allocated by the network side for the MS is 10ms, and the allocated uplink control time slot is a time slot pair: TN2 in TN2 and TN3 , at this time, the network side and the MS must predetermine whether the MS should send the uplink control block on TN2 and TN3 within 0-10ms after the sending time indicated by the RRBP, or send the uplink control block on TN2 within 10-20ms after the sending time indicated by the RRBP. and send uplink control blocks on TN3. In practical applications, according to the uplink control time slot identifier allocated for the MS by the network side, there are several methods for determining the sending time of the uplink control block as follows:
一、当网络侧为MS分配的TTI指示上行控制块应该在时隙对上发送时,若网络侧为MS分配的上行控制时隙为该时隙对中的前一个时隙,则在网络侧对下行TBF设置RRBP进行轮询时,MS在RRBP指示的发送时刻之后的0~TTI时刻内发送上行控制块。1. When the TTI allocated by the network side to the MS indicates that the uplink control block should be sent on a time slot pair, if the uplink control time slot allocated by the network side to the MS is the previous time slot in the time slot pair, then the network side When polling the downlink TBF setting RRBP, the MS sends the uplink control block within 0~TTI time after the sending time indicated by the RRBP.
如图6-1所示,当网络侧要对20ms TBF1进行轮询时,若网络侧为MS分配的上行控制时隙为TN2,且设定上行控制时隙的TTI为10ms,且TN2与TN3构成时隙对,且TN2、TN3上分配有上行RTTI TBF时,则MS在RRBP指示的时刻之后0~10ms内在TN2和TN3时隙上发送上行控制块,这样网络侧就可将RRBP指示的发送时刻之后10~20ms内的TN2和TN3时隙分配给其它MS使用。As shown in Figure 6-1, when the network side wants to poll 20ms TBF1, if the uplink control time slot allocated by the network side to the MS is TN2, and the TTI of the uplink control time slot is set to 10ms, and TN2 and TN3 When a pair of time slots is formed, and uplink RTTI TBFs are allocated on TN2 and TN3, the MS sends uplink control blocks on the time slots TN2 and TN3 within 0-10 ms after the time indicated by RRBP, so that the network side can send the RTTI TBF indicated by RRBP The TN2 and TN3 time slots within 10-20 ms after the time are allocated to other MSs.
二、当网络侧为MS分配的TTI指示上行控制块应该在时隙对上发送时,若网络侧为MS分配的上行控制时隙为该时隙对中的后一个时隙,则在网络侧对下行TBF设置RRBP进行轮询时,MS在RRBP指示的发送时刻之后的TTI~2TTI时刻内发送上行控制块。2. When the TTI allocated by the network side to the MS indicates that the uplink control block should be sent on a time slot pair, if the uplink control time slot allocated by the network side to the MS is the last time slot in the time slot pair, the network side When polling the RRBP for the downlink TBF setting, the MS sends the uplink control block within TTI~2TTI after the sending time indicated by the RRBP.
如图6-2所示,当网络侧要对20ms TBF1进行轮询时,若网络侧为MS分配的上行控制时隙为TN3,且设定上行控制时隙的TTI为10ms,且TN2与TN3构成时隙对,且TN2、TN3上分配有上行RTTI TBF时,则MS在RRBP指示的时刻之后10~20ms内在TN2和TN3时隙上发送上行控制块,这样网络侧就可将RRBP指示的发送时刻之后0~20ms内的TN2和TN3时隙分配给其它MS使用。As shown in Figure 6-2, when the network side wants to poll 20ms TBF1, if the uplink control time slot assigned by the network side to the MS is TN3, and the TTI of the uplink control time slot is set to 10ms, and TN2 and TN3 When a pair of time slots is formed, and uplink RTTI TBFs are assigned to TN2 and TN3, the MS sends uplink control blocks on TN2 and TN3 time slots within 10 to 20 ms after the time indicated by RRBP, so that the network side can send the RTTI TBF indicated by RRBP The TN2 and TN3 time slots within 0-20 ms after the time are allocated to other MSs.
三、当网络侧为MS分配的TTI指示上行控制块应该在时隙对上发送时,则不论网络侧为MS分配的上行控制时隙为该时隙对中的前一个时隙还是后一个时隙,在网络侧对下行TBF设置RRBP进行轮询时,MS都在RRBP指示的发送时刻之后的0~TTI时刻内发送上行控制块,即如图6-1所示。3. When the TTI allocated by the network side to the MS indicates that the uplink control block should be sent on the time slot pair, no matter whether the uplink control time slot allocated by the network side to the MS is the previous time slot or the next time slot in the time slot pair When polling the downlink TBF setting RRBP on the network side, the MS sends the uplink control block within 0~TTI after the sending time indicated by the RRBP, as shown in Figure 6-1.
四、当网络侧为MS分配的TTI指示上行控制块应该在时隙对上发送时,则网络侧总是将该时隙对的前一个时隙分配给MS作为上行控制时隙,在网络侧对下行TBF设置RRBP进行轮询时,MS总是在RRBP指示的发送时刻之后的0~TTI时刻内发送上行控制块,即如图6-1所示;或者,当网络侧为MS分配的TTI指示上行控制块应该在时隙对上发送时,则网络侧总是将该时隙对的后一个时隙分配给MS作为上行控制时隙,在网络侧对下行TBF设置RRBP进行轮询时,MS总是在RRBP指示的发送时刻之后的TTI~2TTI时刻内发送上行控制块,即如图6-2所示。4. When the TTI allocated by the network side to the MS indicates that the uplink control block should be sent on the time slot pair, the network side always allocates the previous time slot of the time slot pair to the MS as the uplink control time slot. When polling the RRBP for the downlink TBF setting, the MS always sends the uplink control block within 0~TTI after the sending time indicated by the RRBP, as shown in Figure 6-1; or, when the TTI allocated by the network side for the MS When indicating that the uplink control block should be sent on the time slot pair, the network side always allocates the last time slot of the time slot pair to the MS as the uplink control time slot, and when the network side polls the downlink TBF setting RRBP, The MS always sends the uplink control block within TTI~2TTI after the sending time indicated by RRBP, as shown in Figure 6-2.
可以看出,图5所示实施例一通过网络侧在为MS分配上行控制时隙的同时,通知MS使用该上行控制时隙的TTI,使得在上行控制时隙为时隙对中的一个时隙时,MS可根据所述TTI确定是只使用所述上行控制时隙还是使用包含所述上行控制时隙的时隙对发送上行控制块,合理利用了信道资源。It can be seen that in the first embodiment shown in FIG. 5, the network side notifies the MS of the TTI of using the uplink control time slot while allocating the uplink control time slot for the MS, so that when the uplink control time slot is one of the time slot pair The MS can determine whether to use only the uplink control time slot or use the time slot pair including the uplink control time slot to send the uplink control block according to the TTI, which makes reasonable use of channel resources.
在实际应用中,网络侧在为MS分配上行控制时隙时,还可同时通知MS是否已为该上行控制时隙指定了TTI,这样MS可根据网络侧是否已为该上行控制时隙指定了TTI,确定在该上行控制时隙上使用的TTI。In practical applications, when the network side allocates an uplink control time slot for the MS, it can also notify the MS whether a TTI has been specified for the uplink control time slot at the same time, so that the MS can TTI, to determine the TTI used in the uplink control time slot.

The message carries the identifier of the uplink control time slot, and at the same time carries the information whether the message contains TTI indication and the TTI indication information of the uplink control time slot.
是否包含TTI指示的信息用于指示该包含下行TBF配置信息的相关消息中是否包含TTI指示信息,可通过该包含下行TBF配置信息的相关消息中的1个空闲比特表示。例如:当该比特为0时,表示该包含下行TBF配置信息的相关消息中不包含TTI指示信息;当该比特为1时,表示该包含下行TBF配置信息的相关消息中包含TTI指示信息。The information of whether TTI indication is included is used to indicate whether TTI indication information is included in the related message including downlink TBF configuration information, and can be indicated by 1 idle bit in the related message including downlink TBF configuration information. For example: when this bit is 0, it means that the related message including downlink TBF configuration information does not include TTI indication information; when this bit is 1, it means that the related message including downlink TBF configuration information includes TTI indication information.
表2给出了用于指示包含下行TBF配置信息的相关消息中是否包含TTI指示的比特位、以及用于指示上行控制时隙的TTI的比特位在取不同值时,所代表的TTI。Table 2 shows the bit used to indicate whether the relevant message including the downlink TBF configuration information includes the TTI indication, and the TTI represented by the bit used to indicate the TTI of the uplink control time slot when different values are taken.

以下给出一个应用图8所示实施例的具体例子:A specific example of applying the embodiment shown in Figure 8 is given below:
如图9-1所示,设定MS的最大多时隙能力为:在1个TDMA帧传输时长内,MS最多能够占用5个上、下行时隙。假设当前网络侧在时隙对:0、1,和时隙对:2、3上分别向MS发送10ms的下行TBF1和下行TBF2,且网络侧要对时隙对:0、1上的10ms下行TBF1进行轮询,且为MS分配的上行控制时隙为时隙2,则若MS采用与时隙对:0、1上的下行TBF1相同的TTI:10ms发送上行控制块,则该上行控制块会占用时隙对:2、3,此时,MS占用的上、下行时隙的总数为6个,超出了MS的最大多时隙能力所支持的5个时隙的数目。因此,MS应该采用更大的TTI:20ms来发送上行控制块,如图9-2所示,该上行控制块既可以在时隙2上发送,也可以在时隙3上发送。此时,MS占用的上、下行时隙总数为5,未超出MS的最大多时隙能力,则未占用的另一个时隙可分配给其它MS使用,合理利用了信道资源。As shown in Figure 9-1, the maximum multi-slot capability of the MS is set as follows: within the transmission duration of one TDMA frame, the MS can occupy up to 5 uplink and downlink time slots.
