Description
Technical field
The present invention relates to wireless communication technology field, particularly a kind of non-continuous receiving control method.
Background technology
Along with developing rapidly of mobile communication technology, the disposal ability of portable terminal strengthens rapidly, and the function that provides increases rapidly.Future mobile communication system is when providing the higher availability of frequency spectrum, higher data rate, more colourful multimedia service, and the power problems of its terminal is also more severe.And discontinuous reception technique (Discontinuous Reception DRX) as an energy-conservation key technology of terminal, is the focal issue that industry is paid close attention to always, and this technology has obtained using widely in each mobile communication system.
(Global System for Mobile Communications, GSM) travelling carriage is waken up once every several " multiframes " (being about as much as 1/8th seconds time period) in the system, continues to be in sleep state At All Other Times in global system for mobile communications.System can indicate the travelling carriage per second to wake up and check whether incoming call is arranged for 4 times, or approximately per second wakes up to check whether incoming call is arranged for 1 time.In the operation of discontinuous reception mechanism, processor will cut out the sleep pattern that receiver enters low-power consumption.Timer internal is restarting processor through after the suitable length of one's sleep.
In the discontinuous reception standard of 802.16e system, (Mobile Station MS) has two states to the travelling carriage of dormant mode support: state of activation and resting state.Under state of activation, MS can normally receive and send data, and under resting state, then can't transmit and receive data.Park mode is made up of a plurality of dormancy periods, and wherein each dormancy period comprises a sleep interval and a listening intervals.If MS detects packet and arrives during the listening intervals of park mode, then enter state of activation and receive data, otherwise, enter sleep interval again.And MS can stop resting state at any time and enter state of activation.
At universal mobile telecommunications system (Universal Mobile Telecommunications System, UMTS) in the discontinuous reception standard of system, (User Equipment UE) is divided into three kinds of relevant active states to user terminal: resting state (Sleep period), state of activation (Busy period) and deactivation status (Inactivity period).Wherein, resting state is power save mode, is made up of the sleep stage and the awakening phase that alternately occur, at sleep stage, UE will close Transmit-Receive Unit with the minimizing power consumption, and at awakening phase, UE will open wireless transmit/receive units and monitoring seek channel, to determine whether new descending paging information.If receive paging information, then UE transfers state of activation reception message to; If do not receive paging information, then when current awakening phase finishes, open a new sleep stage and realize continuing energy-conservation.State of activation and deactivation status all are normal accepting states, the receiver of UE is in opening, and when network side had these UE data not send as yet, UE continued to be in state of activation, when this UE data transmission of network side finished, UE entered deactivation status and monitors whether have new data arrival.If there is new data to arrive, then get back to state of activation, otherwise, then after finishing, deactivation status closes wireless transmit/receive units, enter resting state.
In the discontinuous reception standard of LTE system, the residing state of UE is divided into resting state, state of activation and re-transmission state, shown in corresponding being defined as follows:
1, resting state: be similar to the resting state of UMTS, this state is made up of the sleep stage and the awakening phase that alternately occur.At sleep stage, UE closes wireless transmit/receive units with the minimizing power consumption, and at awakening phase, UE opens wireless transmit/receive units and monitors Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) information, and can downlink data receiving.If there is not downlink data transmission, then UE enters sleep stage again; If downlink data transmission is arranged, then UE transfers state of activation to.In the resting state, the initial moment of awakening phase is a series of fixed values, whether enters other state with UE and has nothing to do.
2, state of activation: after UE successfully decoded PDCCH information, subscriber equipment was opened the deexcitation timer, enters state of activation.State of activation refers to that the deexcitation timer carries out the state of timing.The UE of this moment, its Transmit-Receive Unit is in opening.If before the deexcitation timer overflows, there is new downlink data to arrive again, then prolong state of activation by restarting the deexcitation timer, otherwise UE enters resting state;
3, re-transmission state: this state be directed to mix automatic repeat requests mechanism (Hybrid Auto Repeat Request, HARQ).After the data decode failure that UE receives, can enter the re-transmission state of corresponding HARQ instance process then to eNB (enhanced NodeB, enhancement mode NodeB) feedback NACK.The re-transmission state was made up of two stages: a stage is the round-trip delay stage, and another stage is the re-transmission stage.When UE receives data, start the round-trip delay timer, enter the round-trip delay stage.The UE in round-trip delay stage need not the open wireless Transmit-Receive Unit.When the round-trip delay timer overflowed, UE started the re-transmission timer and enters the re-transmission stage, and the UE that retransmits the stage will open its wireless transmit/receive units with the reception data retransmission, and stop to retransmit timer in its moment that receives data.If still failure of the data retransmission of receiving decoding then to eNB feedback NACK, is restarted corresponding re-transmission state, otherwise is finished the re-transmission state.
Document [1] has proposed a kind of based on the method for dibit signaling consumption to realize that the DRX cycle self adaptation is adjusted in the UMTS system.Document [2] is by defining DRX cycle and the deexcitation timer length that an energy saving factor and the time-delay factor realize dynamically adjusting UMTS.Document [3] is by being divided into three classes with all users, to have improved the energy efficiency of IEEE802.16e system and to have promoted user's minimum-rate that system can guarantee by the mode of class scheduling.At first make up a kind of energy computation model in the document [4], and had corresponding motion R2-071285 to be committed to 3GPP (3
RdGeneration Partnership Project, third generation partner program), compared having or not of deexcitation timer and opened the length of duration to the influence of systematic function by emulation then, found out pluses and minuses separately.
Said method is all being innovated aspect the service quality of energy saving of system and system to some extent, can bring the lifting of systematic function under some scene.Yet they fail all to consider that the introducing of discontinuous reception mechanism is to the influence of scheduling mechanism: after introducing discontinuous reception mechanism, though can reduce each user's energy expense (Fig. 1), the system utility value also can descend simultaneously.The system utility value defined is:
Wherein i represents Customs Assigned Number, R
iThe Mean Speed of expression user i, n represents number of users total in the system.
It has embodied this system utility the taking all factors into consideration of throughput of system and fairness, and is the best compromise of throughput of system and fairness.Fig. 2 show Long Term Evolution (Long Term Evolution, after LTE) system adopts different discontinuous reception power-saving mechanisms, the variation of system utility value.As seen from Figure 2, in discontinuous reception mechanism, the minimizing of user's energy expense is always with the cost that is reduced to of system utility value, so the utilization ratio of energy is not significantly improved.

Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
The present invention mainly is the factor by analyzing influence system utility value, design a kind of discontinuous reception mechanism of adjusting deexcitation timer length adaptively, under the prerequisite that does not reduce the system utility value, reduce user's average energy expense, significantly promoted energy efficiency.
(1) shows the present invention at the DRX of user equipment side control device among Fig. 3.Comprise receiver module, CQI measurement and feedback module and discontinuous reception control module.Terminal is at first judged channel condition, therefore needs definition channel conditions threshold value (CQI_threshold).On the other hand, be the frequent transition phenomenon of state that the shake that prevents channel conditions brings, introduced a discontinuous reception parameters self adaptation and adjusted the triggered time (T_trig).To be cell base station compare the compromise gained according to the channel conditions value of all user feedbacks to the channel conditions threshold value, by network side notice terminal when the initialization; The discontinuous reception parameters self adaptation is adjusted the triggered time and need be indicated the time interval of (CQI) feedback to decide according to channel quality, and the CQI feedback interval is more long, and then T_trig is more big, and the CQI feedback interval is more short, and then T_trig is more little.The reason of value is for guaranteeing at T_trig in the time have abundant CQI value to participate in relatively reducing the state variation possibility that the channel rapid fading brings like this.Preferably, (Signal to Interference plus Noise Ratio, SINR) threshold value is the channel conditions threshold value, delimits user's deexcitation timer length according to this threshold value to take from the carrier/interface ratio that adapts to the modulating-coding specification requirement.
(2) show the present invention at the DRX of network side control device among Fig. 3.Comprise CQI detection and analysis module, SOT state of termination track record module and transmitter module.The base station CQI of monitoring terminal constantly changes, and adopts the DRX identical with terminal to adjust mode, and the synchronism by SOT state of termination track record module maintenance network side and end side DRX activationary time realizes the self adaptation adjustment of no extra signaling consumption.
Fig. 4 shows the non-continuous receiving control method flow chart that utilizes said apparatus to realize, comprising:
Step S401, network side is according to wireless communication standard, the parameter of the discontinuous reception mechanism that configurating terminal is initial, described parameter comprises: the discontinuous reception parameters self adaptation is adjusted triggered time T_trig, some CQI threshold values, and the deexcitation timer length in the described parameter is some length values.At each terminal, at first be configured according to this user's the business demand parameter to its discontinuous reception mechanism by network side.Also comprising the user in the parameter of configuration except above-mentioned parameter carries out the required Cycle Length of DRX (DRX Cycle), starts shift time (DRXStart Offset) etc.In the present invention, with the sign of channel conditions indication information (CQI) as terminal use's carrier/interface ratio (SINR).The CQI value is more high, and the current SINR of GC group connector is more high, and namely channel conditions is more good.Along with the rising of terminal CQI, for the deexcitation timer length of this terminal configuration more short.
Step S402, according to wireless communication standard, terminal is measured the channel conditions indication information CQI of self, and described CQI is fed back to network side, and adjusts the deexcitation timer length of self according to described CQI.The adjustment principle is: if the channel conditions that the current channel conditions of terminal be better than records when this terminal is last adjusts described parameter is the deexcitation timer length of this terminal configuration when then being not more than last adjustment for the deexcitation timer length of this terminal configuration; If be inferior to the channel conditions that records when this terminal is last adjusts described parameter, then be that the deexcitation timer length of this terminal configuration is the deexcitation timer length of this terminal configuration when adjusting greater than the last time.
The channel conditions of terminal and some CQI threshold ratios after, the channel conditions of terminal is divided into discrete some states, different states is the different deexcitation timer length of correspondence respectively, under different states, and the deexcitation timer length of terminal when adjusting this state according to described principle.Adjustment is opportunity: the CQI of terminal T_trig continue in the time be lower than corresponding CQI threshold value or be higher than corresponding CQI threshold value the time trigger adjustment to deexcitation timer length.
Step S403, network side are according to the CQI of terminal feedback, and the discontinuous reception mechanism parameter of corresponding terminal of network side storing is adjusted in the variation of the discontinuous reception mechanism parameter of monitoring terminal, thereby keeps network side consistent with the discontinuous reception mechanism parameter of end side.
The concrete mode that network side is judged according to the channel conditions of terminal is: be in the terminal of state i,
If i=1, the duration that its average carrier/interface ratio is lower than the CQI threshold value surpasses T_trig, judges that then this terminal has been converted to state i+1 automatically, otherwise maintains the original state;
If i=n, the duration that its average carrier/interface ratio is higher than the CQI threshold value surpasses T_trig, judges that then this terminal has been converted to state i-1 automatically, otherwise maintains the original state, the SOT state of termination sum of n for dividing;
If i=2,3...n-1, the duration that its average carrier/interface ratio is lower than the CQI threshold value surpasses T_trig, judges that then this terminal has been converted to state i+1 automatically; The duration that its average carrier/interface ratio is higher than the CQI threshold value surpasses T_trig, judges that then this terminal has been converted to state i-1 automatically,
Network side is adjusted the discontinuous reception mechanism parameter of corresponding terminal of network side storing according to the different parameters of terminal state of living in, thereby keeps the consistency of network side and the discontinuous reception mechanism parameter of end side.
By the feedback mechanism of CQI, network side and end side all have whole parameter values that self adaptation is adjusted, thereby do not need other signaling consumption just can realize synchronously.Finish the configuration of discontinuous reception mechanism when terminal after, carry out discontinuous reception according to the existing systems standard.Terminal is adjusted oneself state according to the own CQI information of feeding back then; The CQI information that network side feeds back according to terminal is followed the tracks of SOT state of termination.
The sample table of table 1 Adaptive Modulation and Coding scheme (AMC, Adaptive Modulation and Coding)
Be example in the Adaptive Modulation and Coding mode shown in the table 1, then the pass of the state transitions among Fig. 5 is the detail that DRX changes, camber line wherein represents the condition of status change, and requiring this condition is a period of time (to trigger listening interval, and above-mentioned T_trig) continuous comparison, too frequent to prevent deexcitation timer length variations, thus the stability of a system is impacted.For the terminal that is in the middle of each state is given different deexcitation timer length values, the average channel carrier/interface ratio of this state correspondence is more low, then its deexcitation timer length is more long, and in this way, the fairness between the terminal can access better guarantee.For the poorest user of channel conditions, in fact this partly the transmission rate of user's correspondence be 0, can not dispatched, so its deexcitation timer can not start, can with this partly the user put state ten under to reduce by a state.Its essential implementation is as follows: the base station calculates the average carrier/interface ratio of terminal on all Resource Block according to the channel conditions of terminal feedback, carries out judgement shown in Figure 5 according to average carrier/interface ratio.The duration that is lower than the CQI threshold value as if the average carrier/interface ratio that is in the terminal of state one surpasses the triggering listening interval, judges that then this terminal has been converted to state two automatically; The duration that is higher than threshold value as if the average carrier/interface ratio that is in the terminal of state ten surpasses the triggering listening interval, judges that then this terminal has been converted to state nine automatically; Be in state i (i=2, terminal 3...9), its average carrier/interface ratio are lower than the duration of threshold value and surpass trigger listening interval, judge that then this terminal has been converted to state i+1 automatically; (i=2, the duration that terminal 3...9), its average carrier/interface ratio are higher than threshold value surpasses the triggering listening interval, judges that then this terminal has been converted to state i-1 automatically to be in state i.In end side, each terminal is adjusted the discontinuous receiving state of oneself according to own channel conditions to the base station side feedback.If this terminal is in duration that state one and average carrier/interface ratio be lower than threshold value and surpasses and trigger listening interval, then adjust this SOT state of termination and get the hang of two; If this terminal is in duration that state ten and average carrier/interface ratio be higher than threshold value and surpasses and trigger listening interval, then adjust this SOT state of termination and get the hang of nine; If this terminal be in state i (i=2,3...9) and average carrier/interface ratio duration of being higher than threshold value surpass and trigger listening interval, then adjust this SOT state of termination i-1 that gets the hang of; If this terminal be in state i (i=2,3...9) and average carrier/interface ratio duration of being lower than threshold value surpass and trigger listening interval, then adjust this SOT state of termination i+1 that gets the hang of.In this way, namely the base station can the residing state of clear and definite terminal synchronously can to guarantee strict between terminal and base station, even and lock-out occurs, it is synchronous that system also can recover rapidly.Be noted that if be lower than in the state transitions process or duration of being higher than threshold value is less than the triggering listening interval, then ignore during this period of time the influence to state.
Fig. 6 shows the example of an implementation of the present invention.This figure has illustrated and has got under many threshold values situation of 1.295,3.4625,3.6543,4.7432,5.4524,6.509,9.2851,10.889 and 11.738, when certain user moves to center of housing estate from cell edge, experienced Fig. 6 (on) the change procedure of SINR value, trigger under the listening interval at 200ms, the user finally is stabilized to the embodiment of the state one of the shortest deexcitation timer by the state ten of the longest deexcitation timer.From Fig. 6 (descending) as can be seen, the terminal that changes according to content-adaptive of the present invention, state that can the correct adjustment oneself according to the actual conditions of current channel, and can realize the synchronous of network side and end side.In the process that changes, because may there be some (state of for example locating in more than 60 second among the figure is reciprocal) repeatedly in the influence of decline shake, but influence general trend, and be to carry out at two adjacent states repeatedly, can not produce jump.
Fig. 7 has compared the discontinuous reception mechanism of self adaptation of the present invention (ADRX) collocation method and the performance of existing DRX mechanism on system utility value and user's average energy expense.The basic cycle of DRX is 512ms, and waking duration timer length up is 2ms.The concrete configuration of the ADRX mechanism among the figure is as shown in table 2.As can be seen from Figure 7, be that the existing DRX mechanism of 512ms is compared with deexcitation timer length, the ADRX configuration mode is in the average energy expense that guarantees obviously to have reduced under the prerequisite that the system utility value does not reduce the user, the system utility value that makes every milliwatt energy provide significantly increases, and has namely improved energy efficiency.
