- a forward rate adjustment request including a forward rate downward adjustment request and a forward rate upward adjustment request
- GID group identity
- PN cell pilot offset
- BACK channel Application confirmation channel: The base station uses the channel to confirm the forward rate adjustment request of the terminal; the channel uses Maclndex (MAC channel index) to distinguish different groups in the same cell.
- Maclndex MAC channel index
- the BDRC channel needs to ensure that when multiple terminals of the same group in the same cell simultaneously transmit the forward rate adjustment request, the base station cannot be interfered with each other. Demodulate the transmission content of the terminal.
- the BDRC channel is defined as follows:
- Period mod Duration 0; that is, Period is an integer multiple of Duration, Period and Duration is the length of time of the CDMA system in slots (slots).
- the probability threshold that the forward rate adjustment request needs to be exceeded (referred to as the transmission threshold); indicates the type of adjustment of the forward rate adjustment request, for example, the rate rise or fall, or the step of the rate increase or decrease, or the requested target rate
- the specific meaning is determined by the base station.
- the values sent by the terminals in the group are exactly the same to ensure that the base station can correctly demodulate when the multiple terminals simultaneously send the forward rate adjustment request to the base station (ie, the base station can uniquely determine according to the value of i). Value).
- ⁇ can be dynamically adjusted by the terminal autonomously, so that the number of terminals simultaneously transmitting the forward rate adjustment request in the group is controlled within a certain range, and the specific adjustment method is described below.
- the terminal needs to calculate a random number P before the offset i sends the forward rate adjustment request.
- the terminal can send the forward rate adjustment request at the offset i, otherwise it needs to wait for the next offset or Next send cycle.
- the P value can be calculated using a random number algorithm, and the P value can be limited between 0 and 1.
- the base station After receiving the forward rate adjustment request sent by the terminal, the base station confirms the terminal request by using the BACK channel, that is, all the base stations in the notification group have received the offset i of the current period. After the request is received; after all the terminals in the group receive the acknowledgment indication of the BACK channel, the forward rate adjustment request of the same type as the offset i time cannot be transmitted in the current transmission period, and the request being transmitted is immediately stopped.
- the type of the forward rate adjustment request is: rising and falling; and the forward rate adjustment request corresponding to the offset i is falling. If a terminal sends a forward rate adjustment request at the offset i, the sending period is within the sending period. All terminals can no longer send a descending type of forward rate adjustment request.
- the terminal when the terminal sends a request to the base station to confirm that the request has a delay of no more than one time slot, if the terminal detects the BACK channel confirmation indication in the first time slot of the offset i + 1, the terminal can be known.
- the request was sent at offset i.
- the base station can also use different acknowledgment indications to separately acknowledge requests received by different offsets.
- the pre-reverse channel resources used for unicast include: Forward Traffic, Forward Pilot, RA (Reverse Activity) channel, DRCLock (rate control) Locked channel, RPC channel (Reverse Power Control) channel, ARQ (Automatic Repeat Request) channel, reverse pilot channel, RRI (Reverse Rate Indicator) Channel, DRC (Data Rate Control) channel, DSC (Data Source Control) channel, ACK (ACKnowledgement) channel, Reverse Data channel.

Confirm the forward rate adjustment request sent by the terminal; or use the reverse pilot and other reverse Mac channel or Data (data) channel group cooperation It is a BDRC channel.
- the base station can acknowledge the terminal request as a BACK channel by using an RPC channel, an ARQ channel, or other forward Mac channel or a combination of these channels.
- FIG. 1 is a flowchart of a method for performing forward broadcast rate adjustment between a terminal and a base station according to an embodiment of the present invention; this embodiment uses an example of a forward rate variable broadcast channel applied in CDMA2000 EVDO RevA (version A) as an example of the present invention.
- the description includes the following steps;
- Step 101 The base station establishes a forward broadcast channel, and broadcasts, by using a forward control channel message, resource information of a forward broadcast channel, such as a Maclndex, to the terminal. After receiving the control channel message, the terminal monitors the forward traffic channel that is forwarded to the Maclndex identifier. .
- Step 102 The terminal detects that the forward PER (false alarm rate) of the forward traffic channel is high or the forward C/I (carrier to interference ratio) is low, and the forward rate needs to be reduced.
- Step 103 The terminal calculates a random 3 ⁇ 4 P.
- Step 104 the terminal determines before sending the rate adjustment request to offset i, and W l, P and if P value is less than W 1 is equal to the rate adjustment request is started before BDRC channel transmission; otherwise, the next offset (offset i +1) Recalculate the P value (of course, you can continue to use the current P value), compared with W 1+ i, start sending forward rate adjustment request when the P value is less than or equal to W 1+1 (the maximum duration of transmission) For Duration).
- Step 105 After receiving the forward rate adjustment request sent by the terminal, the base station adjusts the forward rate, and confirms the forward rate adjustment request of the received terminal by using the BACK channel, indicating that the terminal does not need to send the forward direction in the current sending period.
- the rate adjustment request, the terminal that is sending the forward rate adjustment request also stops transmitting.
- Step 106 The terminal detects that the BACK channel is in an acknowledgment state, confirms that its forward rate adjustment request has been received, and therefore stops sending the forward rate adjustment request.
- the present invention sets the transmission threshold W l of the forward rate adjustment request and only When the P value randomly generated by the terminal is less than or equal to the value, the P-value is allowed to send the forward rate adjustment request to the base station. Therefore, the terminal can only be allowed to send the request to the base station with a certain probability, which avoids the excessive terminal sending the request to the base station at the same time. A large amount of waste of communication resources, even causing the problem of base station collapse.
- each terminal needs to dynamically dynamic W 1 . Adjust to achieve the following objectives:
- the base station can timely meet the forward rate adjustment request of the terminal (that is, ensure that the forward rate adjustment request of the terminal can be sent in time).
- the base station mainly uses the following transmission threshold adjustment strategy when setting the (W l 3 ⁇ 4 ) parameter corresponding to each transmission time period (offset) and the terminal autonomously adjusting the value:
- each transmission time period (offset) has a different initial value, that is, each transmission time period (offset) has a different transmission probability value, usually according to the transmission probability. Arranged in order of large (ie, the send threshold is small to large).
- the terminal successfully sends the forward rate downward adjustment request (indicating that the number of terminals that need to adjust the forward rate downward may be more
- the terminal and other terminals can reduce the value corresponding to the transmission time period (offset) of the forward rate down adjustment request, that is, reduce the success rate of the forward rate adjustment request in the subsequent transmission period. To avoid too many terminals sending forward rate adjustment requests at the same time.
- the terminal successfully sends the forward rate downward adjustment request (indicating that there are fewer terminals that need to adjust the forward rate downward)
- the other terminal may increase the value corresponding to the sending time period (offset) of the forward rate adjustment request, that is, increase the success of the forward rate adjustment request in the subsequent sending period. The rate, to avoid the need to adjust the forward rate of the terminal down the long time can not successfully send the request.
- a terminal fails to successfully send the forward rate downward adjustment request, and no transmission delay request is sent by other terminals during all transmission time periods (offsets) of the entire transmission period (indicating that the current need is required) If there are fewer terminals adjusting the forward rate, the terminal may increase the value corresponding to the transmission time period (offset) of the forward rate adjustment request, that is, increase the forward rate to the subsequent transmission period. The success rate of the request is adjusted to avoid that the terminal that needs to adjust the forward rate downwards cannot successfully send the request for a long time.
- N is greater than 1 transmission periods
- any terminal or only the terminal that wishes to send the forward rate upward adjustment request, or is limited to In the previous several cycles, the application has applied for the downward adjustment rate, and now the wireless environment is improved, and the terminal that needs to apply the upward adjustment rate is increased.
- the value corresponding to the transmission time period (offset) of the transmission forward rate upward adjustment request is increased.
- any terminal can reduce the value corresponding to the transmission time period (offset) for transmitting the forward rate upward adjustment request.
- the Wi corresponding to the transmission time period (offset) for transmitting the forward rate downward or upward adjustment request is proportionally, that is, UHIHK>1; and when each Wi is adjusted, it is The value is multiplied by or divided by X (instead of plus or minus X) to maintain the above proportional relationship.
- transmission threshold adjustment strategies 2, 3, 4 can be replaced by the following strategies:
- one transmission period contains one transmission time period (offset) for transmitting the forward rate downward adjustment request: L. L M - i ;
- the corresponding minimum transmission threshold is W mm and the maximum transmission threshold is W max ;
- Select W L and Wu satisfy: W mm ⁇ W L ⁇ Wu ⁇ W max ;
- the transmission time period in which the transmission threshold value is greater than or equal to W L and less than or equal to Wu in the M transmission time periods is set as the target transmission time period.
- any terminal can reduce the transmission time period of the transmission forward rate upward adjustment request.
- any terminal may increase the transmission forward rate upward adjustment request.
- the value corresponding to the transmission time period (offset); in the case of Wu W max , the specific processing method is the same as the strategy (4);
- the W i corresponding to the transmission time period (offset) of the forward rate adjustment request is unchanged.
- the following is an application example to illustrate how the terminal dynamically adjusts the transmission threshold.
- the terminals in the group may all be distributed in the same cell, or a small number of users may be in other cells.
- the configuration of the Period, Duration, ( W 15 3 ⁇ 4 ) value needs to take into account various extreme situations. In a cell with a large number of users, it is possible to prevent too many users from simultaneously transmitting rate control requests. In a cell with less user distribution, it is necessary to ensure that the user can Achieve rate adjustment. At the same time, when the number of cell users changes, the adaptation can be adjusted to a value suitable for the user distribution.
- the adjustment target of each terminal to W i is that it is desirable to transmit a forward rate downward adjustment request in the subsequent transmission period offset 1 , that is, the number of terminals wishing to simultaneously transmit the forward rate adjustment request is not much.
- the transmission threshold corresponding to each downward adjustment of the forward rate offset (offset 0, 1, 2) is multiplied by 4 and adjusted to 0.16, 0.64, 2.56 respectively; if the offset is detected by the BACK channel, there is When the terminal sends the forward rate downward adjustment request, the transmission threshold corresponding to each downward adjustment of the forward rate offset (offset 0, 1, 2) is divided by 4, and is adjusted to 0.01%, 0.04%, respectively. , 0.16%.
- the offsets 1 and 2 will no longer have the user issue the forward rate downward adjustment request, and each of the downward adjustments will adjust the forward rate offset (offset 0, 1, 2)
- the corresponding transmission threshold Wi is divided by 4, so that the forward rate downward adjustment request is transmitted as much as possible at offset 1 (that is, the number of users transmitting the forward rate downward adjustment request is kept within an appropriate range. ).
- Offset 3 is used by the terminal to send a forward rate upward adjustment request to the base station. If the BACK channel of the base station is not set to the acknowledgment state at offsets 0, 1, and 2, it indicates that no user sends the forward rate in the group. The request is adjusted downward, so if the last one or a batch of terminals successfully transmitting the forward rate down adjustment request improves the wireless communication environment, the rate can be increased at offset 3; or within a specified number of transmission periods, if There is no terminal to send the forward rate up or down adjustment request. Any terminal with better wireless communication environment can calculate the random number P. If the P value is less than or equal to W 3 , the rate increase request can be sent.
- FIG. 2 is a flowchart of a method for performing forward broadcast rate adjustment between a terminal and a base station, and autonomously adjusting a value of the terminal according to the embodiment of the present invention; specifically, the following steps are included;
- Step 201 The base station establishes a forward broadcast channel, and broadcasts, by using a forward control channel message, resource information of a forward broadcast channel, such as a Maclndex, to the terminal. After receiving the control channel message, the terminal monitors the forward traffic channel that is forwarded to the Maclndex identifier. .
- Step 202 The terminal detects a forward PER high or a forward C/I drop of the forward traffic channel, and needs to reduce the forward transmit power.
- Step 203 The terminal calculates a random 3 ⁇ 4 P.
- Step 204 The terminal compares P and W Q , and if P is less than or equal to W q , starts to send a forward rate adjustment request on the BDRC channel; otherwise, recalculates the P value at the next offset (offset 1) (of course, the current use may continue to be used.
- Step 205 After receiving the forward rate adjustment request sent by the terminal, the base station adjusts the forward rate, and confirms the forward rate adjustment request of the terminal by using the BACK channel, and indicates that the terminal does not need to send the forward rate adjustment request in the current sending period.
- the terminal that is sending the forward rate adjustment request also stops transmitting.
- Step 206 The terminal detects that the BACK channel is in an acknowledgment state, confirms that the forward rate adjustment request has been received, and stops sending the forward rate adjustment request.
- Step 207 The other terminal in the small cell group detects that a forward rate downward adjustment request occurs at the time of the offset 0, and then reduces the offset (transmission time period) for transmitting the forward rate downward adjustment request. value.
- the above embodiment can be modified in various ways, for example:
- one transmission period is divided into a plurality of transmission periods of length Duration; in fact, one transmission period may be set in one transmission period, and the resource adjustment parameter R corresponding to the transmission period
- the value represents the target value of the rate adjustment, or the increase in the rate increase and the decrease in the rate decrease.
- R - 2, which means that the forward rate is adjusted downward by two units
- R 2, which means that the forward rate is adjusted upward by two units
- R - l l , indicating that the forward rate is adjusted to - 11 ;
- the method of the present invention is described by taking an adjustment of the forward rate as an example, and the method of the present invention is equally applicable to adjusting the power of the forward channel. In fact, whether it is rate adjustment or power adjustment, the channel resources are adjusted for the base station.
- the request for downward adjustment of the forward rate sent by the terminal, or the request for adjusting the power downward is equivalent to sending a request for increasing channel resources; the request for upward adjustment of the forward rate sent by the terminal, or the request for adjusting the power upward Both are equivalent to sending a request to reduce channel resources.
- the terminal is allowed to send the forward rate adjustment request when the calculated random number P is less than or equal to the transmission threshold; in other embodiments of the present invention, the transmission threshold may also be set, when P When the value is greater than or equal to the transmission threshold, the terminal is allowed to send a forward rate adjustment request.
- the values in Table 1 may be set to 0.96, 0.84, 0.36, and 0.96, respectively.
- the terminal is allowed to send a forward rate adjustment request when the P value is in a preset transmittable request value interval.
- setting W 0 to 0.04 is equivalent to setting the above-mentioned transmittable request value interval to be greater than or equal to 0. It is equal to 0.04, that is, [0, 0.04]; Increasing the value of W 0 is equivalent to expanding the above-mentioned transmittable request value range within the range of P, and decreasing w. The value is equivalent to reducing the above-mentioned transmittable request value interval.
- the above-mentioned transmittable request value interval may be composed of a plurality of discontinuous value intervals within a P value range.
- the broadcast multicast multicast channel rate adjustment method of the present invention can change the fixed setting manner of the traditional broadcast multicast channel forward rate, and the forward broadcast rate is adjusted by the user (terminal) in the cell according to the wireless signal strength, and can simultaneously The number of terminals that send the forward rate adjustment request is effectively controlled to avoid causing serious reverse interference.
- the present invention adaptively adjusts the transmission threshold by the terminal, so that the group with more users is simultaneously transmitted.
- the number of terminals requesting rate adjustment is controlled within a safe range, and the group with a small number of users can ensure that the user (terminal) can send the forward rate adjustment request in time, effectively solving the problem of including an indefinite number of users (
- the group of terminals) allocates appropriate forward channel resources and provides the problem of a suitable forward broadcast rate.
