Description

Uplink control time slot allocation method, system and mobile station

technical field

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.

Background technique

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.

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.

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.

When RTTI technology is used, the TTI is usually determined as follows:

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. 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.

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.

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:

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.

Each time slot has a time slot number (TN, Timeslot Number) to identify the time slot.

Step 302: After receiving the message, the MS saves the time slot number of the uplink control time slot carried in the message.

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.

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 step 301.

Step 305: the network side sends the downlink TBF2 carrying the valid RRBP to the MS.

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 step 301.

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.

Step 308: After receiving the message, the MS saves the time slot number of the new uplink control time slot carried in the message.

Step 309: the network side sends the downlink TBF1 carrying the valid RRBP to the MS.

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 step 307.

Step 311: the network side sends the downlink TBF2 carrying the valid RRBP to the MS.

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 step 307.

The shortcoming of prior art is as follows:

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.

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.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

FIG. 5 is a flow chart of allocating uplink control time slots provided by Embodiment 1 of the present invention. As shown in FIG. 5 , the specific steps are as follows:

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.

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.

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.

TTI indication (1 idle bit) meaning 0 The TTI of the uplink control block sent on the uplink control slot is 10ms 1 The TTI of the uplink control block sent on the uplink control slot is 20ms

Table 1 TTI indication setting provided by Embodiment 1 of the present invention

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 step 503; otherwise, executes step 505.

Step 503: The MS determines the TTI corresponding to the TTI indication information carried in the message.

Step 504: The MS uses the TTI determined in step 503 to send the uplink control block on the time slot corresponding to the uplink control time slot identifier, and the procedure ends.

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.

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:

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.

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.

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.

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.

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.

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.

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.

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.

FIG. 7 is a flow chart of allocating uplink control time slots provided by Embodiment 2 of the present invention. As shown in FIG. 7 , the specific steps are as follows:

Step 701: The network side sends a relevant message including downlink TBF configuration information to the MS. 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.

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.

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.

Whether to include TTI indication (1bit) TTI indication (1bit) meaning 0 none Does not contain TTI indication 1 0 The TTI of the uplink control block sent on the uplink control slot is 10ms 1 1 The TTI of the uplink control block sent on the uplink control slot is 20ms

Table 2 TTI indication setting provided by Embodiment 2 of the present invention

Step 702: The MS receives the relevant message including downlink TBF configuration information, and judges whether the message carries an uplink control time slot identifier, and if so, executes step 704; otherwise, executes step 703.

Step 703: The MS uses the TTI of the downlink TBF to send the uplink control block on the time slot used by the downlink TBF, and the procedure ends.

Step 704: The MS judges whether the message contains TTI indication information according to whether the message carries TTI indication information, and if so, executes step 706; otherwise, executes step 705.

Step 705: The MS uses the TTI of the downlink TBF to send the uplink control block on the time slot corresponding to the uplink control time slot identifier, and the procedure ends.

Step 706: The MS determines the TTI corresponding to the TTI indication information carried in the message.

Step 707: The MS sends the uplink control block on the time slot corresponding to the uplink control time slot identifier carried in the message according to the TTI determined in step 706.

The embodiments shown in Fig. 5 and Fig. 7 provide the method of specifying the TTI of the uplink control time slot at the same time when the network side allocates the uplink control time slot for the MS, so as to avoid the waste of channel resources; An embodiment of determining the TTI of the uplink control time slot according to its own multi-slot capability:

FIG. 8 is a flow chart of allocating uplink control time slots provided by Embodiment 3 of the present invention. As shown in FIG. 8 , the specific steps are as follows:

Step 801: 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.

Step 802: The MS judges whether the message indicates that an uplink TBF is allocated to the time slot corresponding to the uplink control time slot identifier, and if so, executes step 803; otherwise, executes step 804.

The related message including the downlink TBF configuration information will carry the corresponding relationship between each uplink TBF allocated for the MS by the network side and the identifier of the time slot where the uplink TBF is located.

Step 803: The MS uses the TTI of the uplink TBF to send the uplink control block on the time slot corresponding to the uplink control time slot identifier, and the procedure ends.

Step 804: The MS judges whether the TTI of the downlink TBF configured on the time slot corresponding to the uplink control time slot identifier will exceed the multi-slot capability of the MS when sending the uplink control block. If so, perform step 805; otherwise, perform step 804. 806.

The allocation of the uplink control time slot for the MS by the network side indicates that a downlink TBF must be configured on the uplink control time slot.

Step 805: The MS determines a TTI for the uplink control block that will not exceed the multi-slot capability of the MS, and uses the TTI to send the uplink control block on the time slot corresponding to the uplink control time slot identifier, and the process ends.

Step 806: The MS uses the TTI of the downlink TBF configured on the time slot corresponding to the uplink control time slot identifier to send an uplink control block on the time slot corresponding to the uplink control time slot identifier.

A specific example of applying the embodiment shown in Figure 8 is given below:

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. Assume that the current network side sends 10ms downlink TBF1 and downlink TBF2 to the MS on time slot pair: 0, 1, and time slot pair: 2, 3 respectively, and the network side wants to send 10ms downlink time slot pair: 0, 1 TBF1 performs polling, and the uplink control time slot allocated to the MS is time slot 2, if the MS uses the same TTI as the downlink TBF1 on the time slot pair: 0 and 1: 10ms to send the uplink control block, the uplink control block Time slot pairs will be occupied: 2, 3. At this time, the total number of uplink and downlink time slots occupied by the MS is 6, which exceeds the number of 5 time slots supported by the maximum multi-slot capability of the MS. Therefore, the MS should use a larger TTI: 20ms to send the uplink control block. As shown in Figure 9-2, the uplink control block can be sent on time slot 2 or time slot 3. At this time, the total number of uplink and downlink time slots occupied by the MS is 5, and if the maximum multi-slot capability of the MS is not exceeded, another unoccupied time slot can be allocated to other MSs, which makes reasonable use of channel resources.

FIG. 10 shows a system composition diagram for allocating uplink control time slots using Embodiments 1 and 2 of the present invention. As shown in FIG. 10 , the system mainly includes: a network side 101 and an MS 102, wherein:
