Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is directed to a reference dial of a wireless communication device, and more particularly to power consumption control of such a reference oscillator. [Prior Art] There is an algorithm for correcting a low-cost clock with respect to a high-precision clock, also called a master clock. This allows the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ '...line transmission/receiving units (WTRUs) and other mobile _ gods called Chang Weishou. Should be designed in == Jiqing · canning, village _ activity time alone to reduce the power consumption and extend battery life, lying in a certain interval at this time. Configuration, : When it is _ even _ line, minimize the inactivity time of its function _: == wake up the brake _ ring. In __, (9) materials and financial methods and hardware

5 2 Shut down. These methods and hardware that are required to maintain the _f4 ’ step and communicate with the base station are temporarily turned back on. Most handheld WTRUs today include a low-precision I7 slamming clock (RTC) in addition to the high-precision master clock. The main clock is typically controlled by the temperature of the crystal oscillator. The RTC is typically used to reduce the amount of Wei on the amount of Wei, and this component hopes to replace the τ〇ω财DRX_Na timing function. However, in DRX lying hunger on the four sides, the first, RTC typically = significantly lower than ταω (such as the lion-base ratio of 76. 8 million Hz) = work. The frequency accuracy of the second 'RTC' is not as low as the frequency accuracy of the TCx〇. Third, due to different environmental reasons such as temperature changes, the frequency shift of rtc is greater than the frequency shift of ταω. The fourth 'RTC typically operates asynchronously with Tcx. Because of some reasons, the typical dysfunction of the DRX class provides a timing function. SUMMARY OF THE INVENTION WTRUs include high-consumption, high-speed, high-precision, and high-stability reference oscillators such as TCXO with lower power consumption, lower speed, lower accuracy, and lower stability RTC. The TCXO symbolically provides the WT_Timekeeping function. The RTC itself does not provide sufficient timing and accurate timing capabilities for the WTRU. To minimize power consumption and use non-continuous reception (DRX) operations, TCXQ is confusing, and the RTC provides the WTRU's timing function during these shutdown times. Correction between TCX〇 and RTC and the same jHb^RTC·provided timekeeping function are sufficiently accurate and accurate. [Embodiment] As used herein, the name, wirelessly transmitted/received in a user equipment, station, mobile station, fixed & production 4 mobile subscriber element, pager, or any other capable of being in the absence of (4) Any other type of contact surface device in which the back base B-node and the base station (4) m are rotated in a scale environment. Gu-Sew-seam--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Method combination _ low solution and low accuracy record ^ by using low power oscillation n, can achieve longer battery life type 1, low: force rate and low accuracy oscillator operation in higher power high quasi-hybrid oscillator It is of the order of low frequency. For example, in an exemplary embodiment, the coffee maker operating as a low power clock operates at an industrial high of 32,768 kilometers, and the RTC operates to reduce speed. Although the use of RTCs for handheld WTRUs is common, this implementation is woven into the ability to use RTC lion-like operations. The sleep timer (ST) algorithm is used to perform DRX timing and to allow the primary TCX to be throttled' to reduce the power consumption of the standby WTRU, TCX(R) can be turned off during the DRX sleep interval. When the TCXO is turned off, the low power crystal oscillator 1327038 or RTC is used to control the Drx timing until the TCX is turned back on. For this purpose, an instant clock based on an industry standard crystal or other standard clock circuit is used as the RTC. The RTC is combined with a sleep timer algorithm that overcomes the problem of RTC used in the drx mode. The RTC can be any suitable oscillator or clock, which does not change the algorithm; only its parameters are changed. The application of the invention is described in relation to DRX, which is explicitly provided for the UMTS standard. However, the present invention is applicable to wtru with standard-independent sleep modes, such as a specific embodiment of DRX and another specific embodiment of a non-standard based sleep interval. Figure 1 is a diagram showing the WTRU operation in the active mode of the active 11 and the DRX 12 in the silk mode u, the WTRU provides the Wang Tong 1 work & There is a power saving mode during the partial communication frame. Generally, the WTRU is fully operational, actively uses the TCX 〇 17 to be synchronized by the synchronization device, and is operated by the device 15... operable by the RTC device 18 The power of the month &, but the communication device 13 mainly relies on the TCX〇17. The field WTRU is in the DRX mode (2) synchronization and timing function is indicated by the synchronous 4 device 24 and the timing device μ but is represented by decreasing the level. Wei (4) is able to identify the __ model red material, and the maintenance process to a limited extent 'this fine reduction _ step and timing ability to complete, this drop seems to use TCXO 27's needs, and makes it possible to rely on RTC 28 . The i-th diagram shows the difference in phase, and the physical components of the different TCX〇s P, 27 and a, 28 of the money are executed by the same physical device. The operations performed during the sleep mode include finding the paging channel, performing the cell reselection measurement, and checking the user activity. When adorning the page, please (10) turn on sleep = and enter the active mode to be described. The sleep timer can control its active and DRX components and enter synchronized updates based on the algorithm. The Wei timer algorithm includes the main_loop component, the general-system active loop (four)-and the DRX component and the DRX operation—such as in the active loop, the active loop component maintains the operation under the TCXQ and maintains the operation of transferring to the RTC. ability. The active loop component includes a synchronization update and a decision as to whether the WTRU should enter the DRX mode. The decision of whether the WTRU should enter the DRX mode is based on a predetermined inactivity decision. The quasi-like examples of entering the DRX mode include the end of the conversation, the time-off _ inactivity, and the untargeted enough _ meta-search activity. And the predetermined number of consecutive unsuccessful cell scale activities. The specific criteria are a function of the WTRU. In a particular embodiment, the RTC frequency measurement is performed. However, RTC frequency measurements can be avoided as this can be performed at the DR component. The WTRU enters DRx mode when it is determined that the active time interval is not recognized by the WTRU. The DRX | and 'RTC frequency measurements are performed on a periodic basis to maintain synchronization and a decision as to whether to return to the active mode. The components of Figures 3 and 4 can be implemented using integrated circuits, such as integrated circuits (views), multiple ICs, discrete components, or a combination of busy (8) and discrete components tailored to a particular application. Figure 2 shows the input and output signals of the sleep meter calculation (4). The master clock and the DRX job length are measured by the transmission frequency. 83 The calculation 88 is then performed for the wake-up and sleep positions, which is ultimately used to generate The number of wakeups is 93. The τοω boot, τοω shutdown, and the next paging opportunity _ or synchronization update to the output of the algorithm 80. The interaction of reading other receiver algorithms while sleeping si' is shown as Box® in Figure 3. Wei Jingn's secret is based on the sleep timer method described later. The 3rd ® block shows the parent interaction of the sleep meter and other receiver synchronization methods. The components include a timing manager, an ADC circuit, an AGC circuit 113 reception, a filter circuit η*, a frequency estimation circuit ns, a loop filter 116, a digital analog converter (DAC) 117, and a TCXO 118. A frame timing correction (FTC) circuit 121, and a master clock 126, an RTC 127, and a sleep timer 128 are also shown. This circuit implements an algorithm responsible for obtaining and maintaining frame synchronization of the receiver. The ADC circuit 112, the AGC circuit in, the receive filter circuit 114, the frequency estimation circuit 115, the loop filter 116, the DAC 117, and the TCXO 118 form a frequency estimate 1327038 loop 131. Timing manager m, ADC circuit 112, AGC circuit 113, receive chopper circuit 114, and FTC circuit 121 provide frame synchronization loop 132. In this particular embodiment, the sleep timer 128 receives signals from the master clock 126 and the RTC 127, which ultimately provide signals to turn the TCX 〇 118 on and off. The input system is as follows: 1) the master clock (MC) has a nominal frequency of 76.8 megahertz (20X chip rate); and 2) the RTC has a nominal frequency of 32,768 Hz. The control aspects are as follows: 1) The frame-wise DRX cycle length is provided as an input to the algorithm; 2) the next event is the binary input of the paging block or the synchronized update block; and 3) The first MC pulse starting with PO. The output is as follows. l) TCX 〇 shutdown shows tcx 时间 power should be turned off ' 2) TCX 〇 boot does not show RTC pulse mode Tcx 〇 power on time; and 3) next - one; PO or synchronous update Location: Depending on the paging block being considered, the next wakeup time can be PO or synchronized during the update. This output shows the beginning of these events in MC pulses (through rate). In the sleep mode _ the execution of the ride to find the paging channel, the execution of the cell re-selection test and the detection of household activity, if there is a paging, then w na leave the sleep mode and enter the active mode. A continuous method of measuring the strongest cells at any known time in the paging block is then selected, as shown in FIG. Figure 4 is a timing diagram of the processing of the layer 1 in the DRX mode, the sleep timer m Lion County. Gu Jing privately suppresses Na's different parts. The door = rrRTc fresh measurement, this calculation is divided into 11⁄4 in each steel step update time, 1 thousand 筮

/, no (four) 4 picture 'frequency measurement is also only in the WTRU into DRX 詈Γ: stay eight, the second part of the cool method is responsible for displaying P 〇 or synchronization update bit 'in the heart knife during the DRX cycle for each p 〇 operation . This two-part algorithm is considered to calculate the algorithm of the reader, and other algorithms can be used. In the particular example shown by the figure, the frame offset is followed by a synchronization update period, followed by a synchronization update block. A series of paging blocks i7i loss is = out. The midnight RX face period 181_183 is shown 'which is generally preceded by other activities such as paging blocks 172, 173 or synchronous update block 164. During sleep, such as during sleep, before the purchase of 83 during the RX warm-up period. The synchronization update period (6) is before the synchronization update block 164. The _ preheating is about 5 gram of TCXQ parameters to make tcxo warm up 'it is approximately equal to 5 milliseconds of MC (2 冲 impulse, the number of pulses in this embodiment is set to 384000. DRX The desire to identify the period of relative inactivity 'which is shut down by the various secrets of the medical profession'. The sleepy (4) provides the age of the save. The WTRU is told that it must wake up to receive the timing of the transfer data. DRX is used for space Mode and connection mode for CELL PCH and 1327038 ·« > m-pch state in connected mode. During DRX, when the command is set by RRC (Radio Resource Controller) based on system data, the WTRU must be in P〇s Wake up. p〇 shows the beginning of the paging block. 'For each of these steps, the RRC is responsible for scheduling when, how long, and which channel layer 1 must listen to. The time difference between two P〇s for a particular WTRU is called the length of the DRX cycle. - PO corresponds to a paging block, and the paging block is composed of a number of frames and includes: 1) a paging guidance channel (PICH) block consisting of 2 or 4 paging guides (Pis); 2) The gap period consisting of 2, 4, or 8 frames, Physical resources may be used by other channels; and 3) paging channel (PCH) blocks consisting of 2 to paging content frames of one to eight paging groups. When using DRX, the WTRU is only required to be required per DRX cycle. Monitor one PI in a PO, and the timing diagram of the paging block is shown in Figure 4. The period length can vary from 8 to 512 frames. For example, in idle mode, the DRX period length may be 0.64, 1.28, 2.56, and 5.12. Seconds; and in the CELL/URA-PCH state, the possible DRX cycle lengths are 〇.〇8, 0.16, 0.32, 0.64, 1.28, 2.56, and 5 12 seconds.

During DRX, the WTRU should periodically update its frame and timing synchronization to be able to successfully read Pis and perform cell reselection measurements. Therefore, the periodic DRX activity of layer i includes cell reselection and related measurements, monitoring PIs, and maintaining frame and timing synchronization. 13 1327038 *· \

If the WTRU detects that it is paged via the associated PI, it reads 1^, accesses the paging content, otherwise it returns to sleep. U If the TCXO is operated continuously, it will consume 2 amps maximum current from 3 volts nominal DC power supply or 6.0 milliwatt power supply. For additional power saving, Ding 匸 〇 can be turned off during DRX sleep. When TCX〇 is turned off, the sleep timer is used to schedule the wake-up times of tcxo for the start of the p〇s or synchronization update period. The power consumption of the RTC compared to the Tcx〇 is typically significant, at a mA amp size from a 3 volt volt DC supply or 3. 〇 milliwatts. The use of RTC is accompanied by three problems. First, the resolution of the RTC does not meet the requirements of some wireless systems, such as the Wideband Division Multiple Access (Wcdma) Time Division Duplex (TDD) mode. The typical frequency of the RTC is Hertz. The minimum resolution of the illusion microsecond or 117.19 wafer or 2,343·8 fox samples (10) megahertz). The second question ^ RTC _ rate accuracy, RTC production frequency is different from the standard conversion rate, the gap is as much as one millionth of the maximum deviation. Third, the coffee is low. Therefore, the problem is that the frequency shift rate will not be more than 〇3 million two = per knife | or 0.005 millionth per second is fast, this frequency shift rate is typical On the top of the "body #x|H (RTXC)), the poor temperature sensitivity makes the special knife cut crystal. Because these oscillators are not as special as they are, they are less expensive. The sleep leaf subtraction algorithm consists of two parts, 1TC fresh measurement and sleep meter scheduling. Frequency measurements are periodically performed during the DRX 4 shield ring to overcome the problem of frequency accuracy and frequency stability. The scheduling section meets the milk decomposition requirements to accurately schedule DRX events when the TCXO is turned off. For RTC丨, any frequency correction is required. It is only necessary to accurately measure the cheek rate of the RTC. The online connection module does not need to be clear and clear, and the TCX〇 is always ON. RTC fresh only before the _DRX cycle and during the DRX period. For what is needed. The update rate should be such that the total frequency accuracy should be around 1 million. The sleep timing H algorithm interacts with the timing administrator function, and the next p〇 or synchronized update output recognizes the timing management s MC pulse at the same time as the start of the synchronization update after the wakeup. Since the timing administrator's p〇 starts the input identification, the PQ starts after the wakeup to the _timer method. If the FTC changes the frame timing after the synchronization update, the riding finger* Ρ〇 start time side is the _ update timing. : Shouting timing 11 calculations New comparison (four) clock fresh measurement and sleep timer tune j. Regarding the instant clock frequency measurement, Fig. 5 is a timing chart of the rtc fresh estimation window according to the present invention. In order to accurately measure the RTC frequency, the number of main clock pulses (7) is 272 rpm between the long and the gates d. The main clock has a frequency of 768 megahertz, which is the rate of the crystal, because the New York woman, _ to τ 〇 ω 'the worst difference is (5) two million because there is no correction to the RTC, the accuracy of the TCX 〇 Sex does not affect the accuracy of the rtc frequency measurement. As a result, the accuracy of the RTC frequency measurement can be increased as desired by increasing the frequency estimation window size. For the estimated 1 millionth of the coffee frequency, the 1327038 must measure 10 million of the main clock (MC) pulse 271. When the frequency estimation window is selected to be 4096 RTC pulses ("tics,,"), its nominal RTC frequency of 32,768 Hz and the main clock frequency of 76·8 Hz include the beginning of the 9,600,0G0 MC pulse ❶ frequency estimation window. And end by RTC pulse 27 i

The start mc pulse count of the start of the 'RTC pulse 271' is triggered. At the beginning of the 4096th RTC pulse 271, the Mc count is stopped and the MC counter value is used to estimate the frequency. The frequency estimation window is maintained for approximately 125 milliseconds or 13 frames, and this frequency estimation is not performed in the active connection mode, except only before entering the DRX cycle. In this case, the 'frequency measurement occurs anywhere in the last frame before entering the DRX cycle. ° In the DRX touch _, the drunk measurement is executed during the new period of every fine money. 'Frequency measurement 1 and treatment should be copper. The step is more 峨 _ last 13 his box occurs, making TCXO the most ok. The update frequency meter is used for the next paging block.

KRTC (= 4096): The period (constant) of the frequency estimation window expressed in terms of the number of RTCtics. DRXP: This parameter indicates the distance from the current pQ to the next event in frame mode, which has different values depending on the next event input and the length of the DRX cycle. These values are provided in Table 1. KMC: MC (2〇X) pulses per DRX (for all DRX cycle length lists). ' KRTC : The number of RTC pulses used during frequency estimation, which is set to 4096.

At the beginning of each paging block, the next wake-up time is calculated, which can be done as follows: 1) measure the number of Mc pulses from p〇 to the next RTC pulse (TIC in) ' AMC ; 2) found by table i ; and 3) Calculate BRTC, CRTC, and CMC using the equations in the equation. Figure 7 is a flow chart of the TCX0 shutdown procedure during DRX. After the paging block starts (step 301), it is measured amc (step 302), followed by BRTC, CRTC, and CMC (step 3〇3). These calculations are followed by reading the PICH (step 304), followed by the decision paging. Whether the indicator (ρι) is positive (step 305), if the PI is positive, the WTRU is paged or changed in some settings indicated by the BCCH, so if the PI is positive, the WTRU reads the pCH channel to Find out what the positive value of PI is. If PI is a positive value, pCH is read (step 311), and a decision is made as to whether the data read from the PCH indicates a paged or %^ correction (step 312). If the data read from the PCH indicates that the paging or BCCH correction is as determined in step 312, the TCX0 maintenance operation or the DRX mode ends (step 313). If the value is not positive as determined in step 3〇5, or if pch does not indicate that paging 1 or BCCH correction is as determined in step 312, then a decision is made as to whether the current p〇 correctly follows the synchronization update (step 321). If the current p〇 correctly follows the synchronous update 'this method waits until the AFC and TFC converge (step 322), and when the AFC and TFC convergence decide whether the distance from the AFC/TFC convergence statement to the next event is greater than 1 message Box (step 323). If the distance from the AFC/TFC convergence statement to the start of the next event is greater than 1 frame, the TCX〇OFF and 〇1〇^ modes continue (step 324) 'If the AFC/TFC convergence statement begins to the next event If the distance is no more than 1 frame as determined in step 323, the TCXO remains operational but the DRX mode continues. If the current PO does not follow the synchronization update, as determined in step 321, the proximity search measurement is performed until completion (step 341) 'and the distance between the current p〇 and the next synchronization update is less than 17 frames. Deciding (step 342), if the distance from the current PO to the next synchronous update is less than 17 frames, the TCXO is turned off and the DRX mode continues (step 324), if the distance from the current p〇 to the next synchronous update begins Not less than 17 frames, the TCX remains operational but the DRx mode continues.

19 1327038 In operation, the next sleep timer event is to schedule the TCXO shutdown, which is outlined in the flowchart. As seen in the flow chart, there are three final scheduling conditions for each DRX cycle: l) TCXO is turned off, the WTRU maintains the DRX and applies the sleep timer algorithm; 2) TCXO maintains operation and wtrU because of the conditions shown in the flowchart The clock reference used to maintain the DRX' is TCXO and the sleep timer algorithm is not used; and 3) the TCXO maintains operation and the WTRU must leave Drx. In this case, the WTRU has been paged or BCCH correction data is present.

The final step of the Hai method is the wake-up of the next event. The wake-up method is as follows: 1) Turn on TCX〇 at the time BRTC〇 BRJC after the last p〇 pulse; 2) Wait until time CRTC; 3) Calculate the owner from the coffee Clock pulse; ) The CMC master clock pulse 'time is approximately the same as the start of the next event, ie the first chip of the first time slot of the I event; and 5) the method of repeating each coffee cycle until the WTRU_ DRX cycle .

20 - An advantage of the present invention is that it implements a very simple method, which avoids 2 clocks; the need for positive timing, the timing quasi-mixing can be controlled by changing the length of the coffee compartment or the frequency of the clock, which is controlled by the method. The specific embodiment does not correct the fact that the low-accuracy clock is measured but only its frequency is measured.
