Description

- CC power control method and device Wood domain The communication field is especially related to the S-SCC e3 high-speed shared control in the first-generation communication system S PA high-speed sub-segment. Background Wood S-SCC carries S-SC high-speed sharing control information in S PA. O proposed in 7 that S-SCC e3 is used to carry the control information of the sheep or stream S-SC introduced in O. In S6 of the S-SCC e bit b and the bits of the S-SCC e3 stream of the S-SCC e3 stream, the bits of the S-SCC e and S-SCC e3 streams are not the same. The control of S-SCC to S-SC is particularly important for S-SCC and its rate is caused by S-SCC. Currently S-SCC fixed

Take S-SC. However, the use of a fixed rate is only a small rate of money, resulting in wasted resources and the need for a large rate of inability to meet the demand can not be S-SC. The fixed rate with the S-SCC is caused by its users. The purpose of the description in the existing wood is to mention

The S-SCC rate control method device has the same rate of S-SCC as it can reduce its users, and its device supports more than O. The medium-side aspect of the S-SCC rate control method package step S202 receives the high-speed physical control AC AC information high-speed sharing control of the external rate step S204 high-speed physical control letter indicating the internal rate Step S206 compares the rate of the high-speed sharing control of the rate-in-progress rate rate rate rate to the rate of the high-speed sharing control at the rate of the step S208. Where step S202 is preceded by the following steps in rate control

The slope tolerance period, the shielding period, the rate, and the shielding indication. The step of the high-speed physical control AC AC information high-speed sharing control received in step S202 includes the AC AC high-speed sharing control.

If you do not receive the result, then the high-speed sharing control will be. Among the AC AC's ambitions are all AC's AC mainstream AC's AC mainstream AC's AC where step S202 is packaged as follows Step S202-2 Upon receiving high speed physical control AC AC information update tolerance if masked Indicates that there is an outside rate. If the indication is blocked, the rate is not exceeded. The step of the step rate in step S202 is tolerated to a value less than the tolerance period equal to the rate. The value tolerated is equal to the tolerance period is less than the lower rate. The value tolerated is equal to the tolerance period equal to

Or the value tolerated is less than the tolerance period is less than the rate. The value of the rate is equal to the value of the lower rate of the value equal to it. Wherein in step S204, the following rate is S SCC CPC

The mapping of the letter indication is indicated

. The same mapping indicates that the size S c / o ) is the same. The wood scheme has the following wood fruit rate control method sheep S-SCC e3 and 2 part rate control method users do not need quartering and each method to take advantage of the rate of S-SCC

And improved S-SCC. The rate of the same factor can reduce the number of users. Other special features of this book will be made clear in the Ming and Qing dynasty. The purpose of this and its In the Ming, the requirements, and the special points pointed out in the book. The steps that are not mentioned in this paragraph are understood to be part of the original one. In the middle of the S-SCC e3 flow rate control, the process is the S-SCC rate control method. The process is the S-SCC e3 flow rate control process. The S-SCC e3 is the S-SCC e3. The out-of-flow rate control flow is illustrated by the S-SCC rate control device of the present invention. Mode This S-SCC e3 flow rate control method includes the rate control and the out-of-rate control part. The internal rate control is the CQ indication of the S-PCC high-speed physical control). S-PCC is eACQ or e CQ in mode where only sheep CQ and eA flow in sheep. This S-PCC is the e A stream. The external rate control S-PCC AC / AC / The following is a way of closing. This is the S-SCC e3 flow rate control of the current process. In this case, the S-PCC will AC AC and CQ ode ode AC AC rate. Control. The ode's C is controlled by the measurement rate offset). Among them is the C configuration od. The rate internal rate control and the out-of-rate control of the S-SCC e3 stream are jointly determined. The S-SCC rate calculated by comparing juices at a given rate is greater than the rate of S-SCC. The S-SCC rate calculated by the juice is lower than the rate of the S-SCC below. 2 is the S-SCC rate control method of the present application. The method package step S202 receives the high speed physical control AC AC information high speed sharing control

Exceeding step S204 high speed with physical control of the letter indicating the internal rate step S206

The rate of intrinsic rate of the rate of high-speed sharing control rate is compared with the rate of step S208 to compare the results of high-speed shared control rates. Where step S202 is preceded by the following steps in rate control

What needs to be pointed out is the process of describing the rate. The rate of rest is in this flow to step 2. The mask indication in step 5 is intentional. The following steps of the Hugh package include the tolerance period, the mask period, the rate, and the mask indication. It tolerates the cycle and determines the expectations. Expectation / tolerance cycle. Step 2 will tolerate the device, the device, and the shield. Step 3 If the AC AC of the S-PCC is yes, then step 4 or step 5 otherwise. Step 4 Tolerance. Step 5 Block the indication. If it is step 6, otherwise step 7. Step 6 Whether the shield is shielded to the masking period. If the mask is masked, otherwise step 3 is not taken. Step 7 is it. If it is a step, otherwise go straight to step 8. The step tolerates whether to tolerate the cycle. If it is step 9, otherwise step 0 step 9 is the result of the rate is not the rate of the next level se sze. Step Step 0 is up. The result is the rate. The se sze step mask indicates that the power is not step 3. Step tolerator and. 5 is an illustration of the S-SCC rate control device of the present application.
