Description
Technical field
The embodiment of the invention relates to communication technical field, relates in particular to a kind of discontinuous receiving method and equipment.
Background technology
Third generation partner program (3rd Generation Partnership Project; Be called for short: 3GPP) leading Long Term Evolution (Long Term Evolution; Be called for short: LTE) research project is the wireless communication technology of a new generation, expects higher data throughout and better network performance.In the LTE system, eat dishes without rice or wine based on OFDM (Orthogonal Frequency Division Multiplexing; Be called for short: OFDM) technology: adopt shared channel to communicate between base station and the terminal, each UE does not have the Radio Resource that oneself exclusively enjoys, subscriber equipment (User Equipment; Be called for short: do not know in advance UE) which the base station send data to oneself constantly.In the LTE system, time shaft is divided into several slots, and the most basic transmission time sheet is a subframe, and each subframe is 1ms at time width, and band width then equals the bandwidth of sub-district.Fig. 1 a is for the structural representation of existing subframe, shown in Fig. 1 a, after UE receives the data of a sub-frame, earlier at Physical Downlink Control Channel (Physical Downlink Control Channel; Be called for short: PDCCH) regional blind check, if find to have the data of this UE oneself, again according to the indication in the PDCCH zone, from Physical Downlink Shared Channel (the Physical Downlink Shared Channel of this subframe; Be called for short: PDSCH) data are taken out in the zone, thereby realize Data Receiving.Since in the OFDM technology, the data of base station selected transmission chunk, then efficiency of transmission is better, and therefore, the base station will select some subframe to send mass data to a UE, then not send out data to this UE in other subframes.But whether UE is in advance and do not know to have in certain subframe oneself data need detect PDCCH in all subframes, cause serious power consumption.
For saving the UE power consumption in the communication system, LTE adopts discontinuous reception (Discontinuous Reception; Be called for short: DRX) mechanism, the essence of DRX are through pre-configured, are base station and UE agreement: only send data in some subframe to UE.DRX can reduce the time that UE detects PDCCH, communicating by letter of UE and base station is concentrated on a part activate in the subframe, and UE only needs to detect PDCCH in the subframe of agreement, can reduce the UE power consumption.But, because the some special subframes of base station possible configuration are for example: be used for location, via node (Relay Node; Be called for short: RN), energy-conservation, inter-cell interference cancellation (Inter-Cell Interference Coordination; Be called for short: ICIC) etc., the perhaps subframe of other new purposes, these special subframes do not have normal PDSCH resource, and data can not be sent to UE at special subframe in the base station.Special subframe is a cell-level, and is all effective to each UE in the sub-district, and the base station can send to all UE in the sub-district with special subframe through broadcast.If the activation subframe of UE is conflicted with the special subframe position; Data can not be sent to this UE in these activation subframes of conflicting with special subframe in the base station; Therefore, need send data to this UE, then possibly can't satisfy the delay requirement of data if activate subframe at these; The data that exceed time delay will be dropped, and cause loss of data.
A kind of scheme that prior art solution special subframe ties up the activation subframe of UE is: the base station is taken the factor of special subframe into account before for UE configuration DRX, avoids activation opportunity and the special subframe of UE to bump.But the activation moments of UE is compressed in the non-special subframe like this, causes the communication load of these non-special subframes to rise.And, have nothing in common with each other owing to be used for the cycle of the special subframe of various uses, have length that weak point is arranged, but available DRX length activation cycle have only several kinds, causes the DRX configuration mode limited, restricted the flexibility ratio that algorithm is realized.In addition, when the special subframe of sub-district changes, need to increase the DRX reconfiguration course.Therefore; In order to realize disposing flexibly; Prior art can also activate subframe according to the real-time adjustment of special subframe and the collision position that activates subframe; The special subframe that need not consider the sub-district during base station configuration DRX distributes, and also need not carry out reprovision to the DRX of UE when revising the special subframe of sub-district, can save the process of signaling configuration.Concrete grammar is: UE obtains the special subframe configuration of sub-district through reading system broadcasting; With activation subframe in oneself DRX activation opportunity relatively; Activate the special subframe that subframe falls into the sub-district if find the DRX of oneself, then automatically with oneself activation subframe to pusher.For example: DRX activate opportunity occupied several sub-frame, UE just with oneself activation subframe to the several subframes of pusher, still, UE need monitor PDCCH in more subframes like this, causes extra power consumption.
In sum, according to the scheme of the real-time adjustment activation subframe of special subframe and the collision position that activates subframe, possibly cause the electric weight waste of UE in the existing DRX technology.

Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Because intelligent terminal needs continually and some data of base station transmits; And each data quantity transmitted is very little, and UE and base station connect before each transfer of data, discharges after the transfer of data to connect again; But each data quantity transmitted is very little; The percentage that signaling occupies in total traffic capacity is very high, and the shared percentage of data is very little, causes communication efficiency low.To this problem, behind DTD, can not discharge connection, and be UE configuration DRX; And activation cycle that configuration is long and short lasting timer (OnDuration timer, timing are the activation opportunity of this UE), the length of activation cycle satisfies the delay requirement of data; As: the data demand time delay is no more than 500ms, can be set, like this activation cycle of 500ms; Even (for example: the data that deliver on the upper strata are received in the base station when just getting into the UE sleep state under the worst case; Need these data be passed to UE, the base station need wait until that next UE activation could pass data opportunity), also can satisfy delay requirement.The advantage of DRX scheme need not connect before being to transmit data at every turn, has saved signaling process, has saved interface-free resources.Because the UE One's name is legion, the base station is a balanced load, and with the activation of these UE configuration of staggering opportunity, the more corresponding UE of each subframe get into states of activation, some UE entering sleep states usually.Fig. 1 b is the sketch map of the mechanism of DRX, and shown in Fig. 1 b, the relevant parameter of DRX mainly comprises cycle, deviant, continues timer (OnDuration timer), deexcitation timer (Inactive timer) etc., and these values of parameters are confirmed by algorithm.Wherein two parameters of cycle and deviant are used for confirming the original position of each activation cycle; UE begins to detect PDCCH in the initial subframe of each activation cycle; Start OnDuration timer simultaneously; If UE does not receive any oneself data before OnDuration timer is overtime, then return dormant state; If UE receives that the base station issues the data of oneself before OnDuration timer is overtime, then start Inactivetimer, activation is prolonged a period of time on opportunity.Therefore, adopt the scheme of DRX, communicating by letter of UE and base station concentrated on a part activate in the subframe, UE only detects PDCCH in the subframe of agreement, has reduced UE and has detected the time of PDCCH, thereby reduced the UE power consumption.
Embodiment one
Fig. 2 a is the flow chart of discontinuous reception (DRX) method that provides of the embodiment of the invention one, and shown in Fig. 2 a, this discontinuous receiving method comprises:
In the embodiment of the invention when current subframe is carried out virtual scheduling to user data, do not have the data of actual needs transmission, and only prolong the activation opportunity that subscriber equipment detects PDCCH through virtual scheduling.
Adopt step 101; If the activation opportunity of subscriber equipment and the special subframe of base station clash; Then UE can receive the virtual scheduling that sends in the conflict subframe base station and activate indication, the subframe that the activation opportunity that said conflict subframe is a subscriber equipment and the special subframe of base station clash on PDCCH.Wherein, the virtual scheduling of the base station transmission of subscriber equipment reception activates to be designated as and can comprise following arbitrary example:
Example one, first virtual scheduling activate indication, and said first virtual scheduling activates the uplink scheduling of indication and confirms that parameter is the first code-point value; Or
Referring to Fig. 2 b, first virtual scheduling activates the sketch map of indication in the discontinuous receiving method that provides for the embodiment of the invention one, wherein; UE is machine testing PDCCH when activating, and judges whether to exist oneself downlink data or uplink scheduling, if the activation of UE conflicts with the special subframe of cell base station opportunity; Also need detect PDCCH; Whether there is the uplink transmission resource indication,, for example then set quantity: transmit ascending data after 4 sub-frame to know if exist.Because the base station need send to UE with the uplink transmission resource indication in PDCCH, use different ascending resources to transmit to guarantee each UE, do not produce conflict.The parameter of this uplink transmission resource indication can be confirmed (UL grant) parameter for uplink scheduling, and the length of ULgrant parameter can be determined by following formula (1):
In formula (1);
is for the resource quantity that uplink transmission resource comprised, and be relevant with upstream bandwidth; Can adopt fast (the Physical Resource Block of physical resource; Be called for short: quantitaes PRB), wherein PRB is the minimum particle size of ascending resource.
is as shown in table 1 below with the relation of upstream bandwidth, can calculate the length of the UL grant parameter under the various bandwidth according to table 1:
The resource indication code-point operating position of table 1, up-link carrier
Can know by last table 1, under each bandwidth, have still untapped code-point in some prior aries, use these still untapped code-points notice UE to prolong activation opportunity in the embodiment of the invention.Make an appointment and use the uplink scheduling of the i.e. first code-point value representation, first virtual scheduling activation of still untapped code-point value indication in which prior art to confirm parameter in UE and base station, this agreement can be stipulated by agreement, also can realize through the rrc layer Signalling exchange.(can be if certain of UE activates that the subframe on opportunity tied up by special subframe for all being tied up; Also can be tied up) for part; The base station is in order to send downlink data to UE; Send first virtual scheduling activation indication with the subframe of conflicting that special subframe clashes to UE opportunity in activation, shown in Fig. 2 b, first virtual scheduling activates indication can be identical with normal uplink scheduling form; It is not an effective code-point value of existing protocol that but first virtual scheduling activates the UL grant parameter of indication, but still untapped code-point value of existing protocol.After UE receives this first code-point value; Start the deexcitation timer (inactivity timer) of DRX; Prolong the activation opportunity of UE; UE can continue to monitor PDCCH before the deexcitation timer expiry, real downlink data can be sent to UE in some activation subframes on the activation opportunity (in the duration before the deexcitation timer expiry) that prolongs in the base station.If also be special subframe the activation opportunity that prolongs, the base station can be continued to send virtual scheduling and activated and indicate on this special subframe, adopts above-mentioned identical method to prolong activation opportunity once more.
Example two, second virtual scheduling activate indication, and the descending allocation of parameters that said second virtual scheduling activates indication is the second code-point value; Or
Referring to Fig. 2 c; Second virtual scheduling activates the sketch map of indication in the discontinuous receiving method that provides for the embodiment of the invention one; If the last data that have the base station to pass to UE of PDSCH; The base station can be indicated on PDCCH, on the PDSCH with the current subframe of notice UE the data of passing to this UE is arranged, and this UE can go to receive.Wherein, UE is machine testing PDCCH when activating, and judges whether to exist oneself downlink data or uplink scheduling, if the activation of UE conflicts with the special subframe of cell base station opportunity; Also need detect PDCCH; To know whether there is the uplink schedule information, still need not detect down dispatch information, because do not carry out downlink data transmission in the special subframe.In the existing agreement; The base station need send to UE with the indication of downlink transfer resource in PDCCH; So that UE correctly finds the downlink data of oneself in the PDSCH zone; The parameter of this downlink transfer resource indication can be descending distribution (DL assignment) parameter, and the length of DL assignment parameter can be confirmed according to following formula (2):
In formula (2);
is relevant with downlink bandwidth;
is as shown in table 2 below with the relation of downlink bandwidth, can calculate the length of the DL assignment parameter under the various bandwidth according to table 2:
The resource indication code-point operating position of table 2, descending carrier
Can be known by last table 2, under each bandwidth, have still untapped code-point in some prior aries, the embodiment of the invention uses these still untapped code-points notice UE to prolong activation opportunity.Make an appointment and use the i.e. second code-point value representation, second virtual scheduling activation of still untapped code-point value indication in which prior art in UE and base station, this agreement can be stipulated by agreement, also can realize through the rrc layer Signalling exchange.If activating, the DRX of UE conflicts with special subframe opportunity; UE detects the descending scheduling of PDCCH as usual; If find the schedule information of oneself; And " DL assignment " is the second code-point value that second virtual scheduling of making an appointment activates indication, then starts the deexcitation timer (inactivity timer) of DRX, prolongs activation opportunity; UE continue to monitor PDCCH, and real downlink data can be sent to UE in the base station in the some activation subframes in the activation opportunity that prolongs.
Example the three, the 3rd virtual scheduling activates indication, and said the 3rd virtual scheduling activates indication and comprises the virtual wireless network temporary mark.
Referring to Fig. 2 d; The 3rd virtual scheduling activates the sketch map of indication in the discontinuous receiving method that provides for the embodiment of the invention one; Wherein, UE can use public Radio Network Temporary Identifier (Radio Network Temporary Identifier in activation opportunity; Be called for short: RNTI) or own privately owned virtual (Dummy) RNTI such as RNTI, monitor PDCCH, judge whether own downlink data or uplink scheduling, wherein public RNTI comprises: pager wireless net network temporary mark (the Paging RNTI of paging use; Be called for short: P-RNTI), system information Radio Network Temporary Identifier (the System Information RNTI that uses of broadcasting; Be called for short: SI-RNTI) or at random insert random access radio network temporary mark (the Random Access RNTI that uses; Be called for short: RA-RNTI) etc., privately owned RNTI then is the RNTI that base station assigns is used to UE when connecting.
When the DRX of UE activates when conflicting with the special subframe of base station opportunity; For guaranteeing in time to issue data, the base station can be that UE distributes a virtual wireless network temporary mark (dummy-RNTI) in advance, when activation conflicts with special subframe opportunity; If UE detects dummy-RNTI in the conflict subframe; Then can the base station can send the 3rd virtual scheduling that carry dummy-RNTI and activate indication,, thereby prolong activation opportunity so that UE starts the deexcitation timer (inactivity timer) of DRX to UE; UE continue to monitor PDCCH, and real downlink data can sent to UE in some activation subframes on the activation opportunity that prolongs in the base station.In the conflict subframe, the transmission of this dummy-RNTI has only the content on the PDCCH, on PDSCH, has no content.
The above-mentioned said first code-point value, the second code-point value or virtual wireless network temporary mark are pre-configured on said subscriber equipment.Can stipulate by agreement.
Example the four, the 4th virtual scheduling activates indication, and said the 4th virtual scheduling activates the physical location that downlink data in the subsequent subframe is carried in indication.
Referring to Fig. 2 e, the 4th virtual scheduling activates the sketch map of indication in the discontinuous receiving method that provides for the embodiment of the invention one, wherein; When the DRX of UE activates when conflicting with the special subframe of base station opportunity; For guaranteeing in time to issue data, the base station can issue a PDCCH instruction earlier in the original DRX activation of UE opportunity, on this PDCCH, the 4th virtual scheduling is activated indication and send to UE; Wherein because the 4th virtual scheduling activates the physical location that carries downlink data in the subsequent subframe in the indication; Therefore the data that do not have actual schedule in current subframe, therefore, can make an appointment for: UE receives that the 4th virtual scheduling that carries the physical location of downlink data in the subsequent subframe activates indication; Start the deexcitation timer (inactivity timer) of DRX, prolong the activation opportunity of UE.And, the 4th virtual scheduling has downlink data block because activating the PDSCH that has indicated PDSCH channel correspondence in follow-up certain sub-frame in the indication; Indicated the position of the physical resource of this downlink data block use simultaneously; After UE receives that the 4th virtual scheduling activates indication, can, the 4th virtual scheduling the activation subframe of the physical location correspondence of downlink data receive the downlink data block that send the base station in activating the subsequent subframe of carrying in the indication.Compare with example one, example four can be practiced thrift PDCCH instruction (promptly only need send downlink data block through PDSCH in the position of the physical resource of appointment, not need another PDCCH to carry out the indication of actual schedule), saves the PDCCH resource.
Wherein, the timing length of deexcitation timer (inactivity timer) can be made an appointment, generally can be for 1～6,8,10,20,30,40,50,60,80, the 100......2560 sub-frame, can certainly be other numbers.After subscriber equipment receives that virtual scheduling activates indication, just can start the deexcitation timer by timing length according to a preconcerted arrangement, thereby with the certain subframe of activation prolongation on opportunity of subscriber equipment.
Alternatively, this discontinuous receiving method can also comprise:
Present embodiment UE is in DRX activation opportunity; Can activate indication according to the virtual scheduling of base station and start the deexcitation timer; Thereby solve DRX and activate the data transmission problems when being occupied by special subframe opportunity, because by the base station indication UE processing that conflicts, so can reduce the power consumption of UE; Simplify the conflict processing procedure of UE, and the UE receptivity is unaffected; Further, if the base station exists some downlink datas need send to this UE, still; This UE conflicts with the special subframe of base station in the activation of DRX opportunity, because downlink data can not be sent to this UE in the conflict subframe in the base station, at this moment indicates UE to start the deexcitation timer again; Like this, UE need not activate the special subframe prolongation activation opportunity of opportunity and base station to the DRX of each conflict, can further alleviate the burden of UE; Reduce the UE power consumption, the receptivity of UE is unaffected and processing procedure is simple.
