Description
Technical field
The present invention relates to moving communicating field, relate in particular to a kind of terminal and transfer the method for continuous reception and terminal, base station to by discontinuous reception.
Background technology
(User Equipment, power consumption UE) have been introduced discontinuous reception (DRX) pattern and have been received (RX) pattern continuously in the mobile communication system in order to save subscriber equipment.Under the DRX pattern, UE is monitoring control channel or data channel periodically, and during the unlisten channel, UE can close receiver, thereby reaches purpose of power saving.Under the RX pattern, continuous monitoring control channel of UE or data channel.
When base station (NodeB) adopted scheduling mode to communicate by letter with UE, NodeB needed this UE of scheduling earlier before UE sends downlink data, and UE is downlink data receiving on the resource of dispatching command appointment; In addition, when UE sends upstream data, also need wait for the dispatching command of NodeB at every turn, on the resource of dispatching command appointment, send upstream data.Because generally, NodeB can not dispatch same UE continuously, and therefore, for power saving, UE is usually operated at the DRX pattern, only when satisfying specified conditions, Cai UE goes to the RX pattern from the DRX pattern.Wherein, this section and hereinafter described DRX be meant the discontinuous monitoring down control channel of UE, RX is meant that UE monitors down control channel continuously.
When NodeB adopted scheduling mode to communicate by letter with UE, UE from the condition that the DRX pattern goes to the RX pattern is: UE obtained uplink transmission resource at present; UE from the condition that the RX pattern goes to the DRX pattern is: UE discharges uplink transmission resource, and does not regain uplink transmission resource or initiate the uplink transmission resource request in buffer time.Wherein, UE needed to send the request of obtaining uplink transmission resource to NodeB earlier before obtaining uplink transmission resource, after NodeB receives this request, just can distribute uplink transmission resource for this UE.
Existing this UE from the deficiency that the DRX pattern goes to the method existence of RX pattern is:
When the downlink data amount was big, NodeB need repeatedly dispatch UE, if during downlink data sends, UE does not obtain uplink transmission resource, and then UE always works in the DRX pattern, so, NodeB can only dispatch this UE during UE monitors down channel, cause the time delay of UE downlink data receiving bigger.
Especially, the transmission intercal (TTI) in time division multiplexing (TDD) system is longer, causes in the TDD system, and the chance of NodeB scheduling UE is less.For example,, suppose in a DRX cycle that the time that UE has 10ms that down control channel is received continuously, NodeB just has only the chance of 2 scheduling UE if TTI is 5ms.In the TDD system, if UE is always to down control channel High-Speed Shared Control Channel (High Speed Shared Control Channel, HS-SCCH) carry out DRX, NodeB is in order to guarantee the transfer of data of UE, in above-mentioned continuous time of reception, have only in the limited chance UE is dispatched, limited the degree of freedom of NodeB scheduling.And in case the channel quality variation of HS-SCCH causes UE decoding incorrect, limited dispatcher can be just more nervous, if miss the dispatcher meeting, NodeB must wait for that next DRX cycle could dispatch UE once more, has increased the time delay that UE transmits data.

Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to accompanying drawing, the embodiment that develops simultaneously, the present invention is described in more detail.
In the embodiment of the invention, when NodeB adopts scheduling mode to communicate by letter with UE, as if UE down control channel is carried out discontinuous monitoring, promptly UE is in the DRX pattern, and then UE changes the RX pattern over to by the DRX pattern when satisfying following arbitrary condition:
Condition 1:UE has uplink transmission data to be sent.
Condition 2:UE receives the uplink synchronous order.
Condition 3:UE receives schedule information.
Condition 4:UE receives that indication enters the order of RX pattern.
For condition 1, when UE had upstream data to be sent, UE carried out RX to down control channel, so, UE can receive the dispatching command that NodeB sends any time during RX, usually, when UE sent upstream data, NodeB was bigger to the probability that this UE sends downlink data, like this, trigger UE with condition 1 and change the RX pattern over to from the DRX pattern, in the time of can reducing downlink data transmission, UE waits for the time delay to down control channel RX.
UE changes the RX pattern over to after NodeB has reported upstream data this situation to be sent.UE can strengthen dedicated channel at channel and insert ascending control channel (E-DCH Random Access Uplink Control Channel at random, E-RUCCH) go up by send first this sign of dispatch request information (SI) to NodeB, reported upstream data this situation to be sent.During UE had upstream data to be sent, UE remained and is in the RX pattern.
For condition 2, in strengthening the TDD system that inserts (Cell-FACH) state fast in the sub-district, there is the situation of UE uplink loss, for example,, then allow this UE uplink loss if UE does not have upstream data to be sent for a long time.NodeB needs to send the uplink synchronous order to this UE earlier before the UE of uplink loss sends downlink data, treat that UE replys confirmation of synchronization message after, NodeB just sends downlink data to this UE.After UE received that the uplink synchronous order enters the RX pattern, UE can receive the dispatching command that NodeB sends any time during RX.
For condition 3, UE receives schedule information and promptly changes the RX pattern over to, makes UE any time during RX to receive the dispatching command that NodeB sends.Wherein, schedule information can comprise special command that carries on the control information of the control information of downlink data transmission or transmitting uplink data or the control channel etc.
For condition 4, NodeB can or strengthen absolute grant channel (E-DCH Absolute Grant Channel at HS-SCCH, E-AGCH) go up the order of between DRX pattern and RX pattern, changing to UE transmission control UE, UE also can be at ascending control channel high-speed shared information channel (High Speed Shared Information Channel, HS-SICH) or E-RUCCH go up to the NodeB feedback message, confirm whether this UE has received described order.On NodeB one of any in HS-SCCH and E-AGCH after the carrying implicit commands, UE can send feedback message to NodeB on HS-SICH and E-RUCCH one of any, for example, NodeB is sending control UE after the order of changing between DRX pattern and RX pattern to UE on the HS-SCCH, and UE sends feedback message to NodeB on E-RUCCH.Send the optional channel of described control command owing to increased NodeB to UE, and UE is to the optional channel of NodeB feedback acknowledgment message, therefore, under the situation of channel resource anxiety, NodeB can in time notify UE to change the RX pattern over to.
After UE entered the RX pattern, HS-SCCH received continuously to down control channel, if after UE enters the RX pattern, NodeB need send order to UE by down control channel E-AGCH, and then UE also can receive continuously to E-AGCH.
Provided NodeB and UE above and adopted under the situation that scheduling mode communicates by letter, UE changes the condition of RX pattern over to by the DRX pattern, in the practical application, also exists UE to change the problem of DRX pattern over to from the RX pattern under which kind of condition.Below in conjunction with Fig. 1, introduce the method that UE changes in detail between DRX pattern and RX pattern.
Fig. 1 is among the present invention, the method flow diagram that UE changes between DRX pattern and RX pattern.As shown in Figure 1, this method specifically comprises the steps:
Step 101, UE is in the DRX pattern.
When UE is in the DRX pattern, down control channel is carried out discontinuous reception according to pre-configured DRX cycle.
Step 102, UE judges whether to satisfy the condition that changes the RX pattern over to.If satisfy condition 1, promptly UE has upstream data to be sent, execution in step 104; If satisfy condition 2 or 3 or 4, promptly UE receives that uplink synchronous order or schedule information or indication enter the order of RX pattern, and execution in step 103 if condition 1 to 4 does not all satisfy, is then returned step 101.
Step 103, UE starts or restarts timer T_Inactivity_Threshold_for_UE_DRX_cycle, changes step 105 over to.
The timing duration of T_Inactivity_Threshold_for_UE_DRX_cycle can be notified UE and NodeB by high-level signaling.
In this step, UE can start or restart timer T_Inactivity_Threshold_for_UE_DRX_cycle in the uplink synchronous order of receiving self or schedule information or indication enter the TTI at moment place of order of RX pattern.UE also can to the NodeB feedback message, show that this UE correctly receives described order or information after described order of receiving self or information, start T_Inactivity_Threshold_for_UE_DRX_cycle in the TTI of place constantly at feedback message.Wherein, UE can judge whether this order or information belong to self by the sign ID that described order or information are carried.
In this step, if UE receives the uplink synchronous order, or schedule information, or indicate when entering the order of RX pattern, T_Inactivity_Threshold_for_UE_DRX_cycle is in time status, then UE is meant that UE directly restarts the described T_Inactivity_Threshold_for_UE_DRX_cycle that is in time status starting T_Inactivity_Threshold_for_UE_DRX_cycle according to described order or information, a T_Inactivity_Threshold_for_UE_DRX_cycle promptly only is set in UE, at any one time, has only a T_Inactivity_Threshold_for_UE_DRX_cycle at most in timing.
Step 104, UE starts or restarts timer T_Inactivity_Timer_for_UE_DRX_cycle.
UE satisfies condition 1 and after changing the RX pattern over to, UE can carry this sign of the 2nd SI in last the upstream data bag PDU that sends, this PDU of notice NodeB is last packet that this UE uploads, and last ACK that this UE receives is the affirmation message that NodeB sends at this PDU, then start buffering timer T_Inactivity_Timer_for_UE_DRX_cycle, described ACK shows that this NodeB correctly receives the PDU that carries the 2nd SI.During the T_Inactivity_Timer_for_UE_DRX_cycle timing, UE keeps the RX pattern, and if this UE has upstream data to be sent again, then T_Inactivity_Timer_for_UE_DRX_cycle stops timing.The timing duration of T_Inactivity_Timer_for_UE_DRX_cycle can be notified UE and NodeB by high-level signaling.When the timing duration of T_Inactivity_Timer_for_UE_DRX_cycle is 0, promptly be equivalent to the situation that UE does not dispose timer T_Inactivity_Timer_for_UE_DRX_cycle, UE receives that described ACK shows that promptly T_Inactivity_Timer_for_UE_DRX_cycle is overtime in other words.The number of T_Inactivity_Timer_for_UE_DRX_cycle is one.
Step 105, UE is in the RX pattern.
The execution sequence of step 103 and step 105, and the execution sequence of step 104 and step 105 is all interchangeable, be that UE can be introduced into the RX pattern, restart timer T_Inactivity_Threshold_for_UE_DRX_cycle or T_Inactivity_Timer_for_UE_DRX_cycle.
Step 106 judges whether T_Inactivity_Threshold_for_UE_DRX_cycle and T_Inactivity_Timer_for_UE_DRX_cycle be all overtime, if, return step 101, otherwise, step 105 returned.
In Fig. 1 method, when UE adopted the order that enters the RX pattern according to indication to enter the scheme of RX pattern, method shown in Figure 1 also can not start timer T_Inactivity_Threshold_for_UE_DRX_cycle and T_InactiVity_Timer_for_UE_DRX_cycle.In addition, UE also can be after receiving that indication enters the order of DRX pattern, and perhaps, UE enters the DRX pattern after NodeB sends feedback message, and wherein, described feedback message shows that this UE has received that indication enters the order of DRX pattern.
Present embodiment proposes, in the TDD system, NodeB can send DRX pattern deexcitation order and the order of DRX mode activation to UE on HS-SCCH or E-AGCH, (E-DCH Physical Uplink Channel E-PUCH) goes up to send and receives the feedback message of described activation command or deexcitation order can to strengthen special-purpose physical uplink channel at HS-SICH or E-RUCCH or up channel.
After UE receives DRX pattern deexcitation order, enter the RX pattern, after UE receives the order of DRX mode activation, between DRX pattern and RX pattern, change according to the method for Fig. 1, wherein, the feedback message in Fig. 1 method comprises the feedback message of receiving described activation command or dimmed command.
In the TDD system, NodeB can send order or deexcitation order of DRX pattern or the order of DRX mode activation that uplink synchronous order or schedule information or indication enter RX pattern or DRX pattern on HS-SCCH or E-AGCH, UE can send feedback message at described order or information on HS-SICH or E-RUCCH or E-PUCH.Wherein, there are the situation of various combinations in the control channel of carrying implicit commands or schedule information and the interchannel of UE feedback message, for example, NodeB sends the implicit commands that indication enters the RX pattern to UE on HS-SCCH, UE sends feedback message to NodeB on E-PUCH, show and receive that described indication enters the implicit commands of RX pattern.
In the practical application, also exist NodeB how to determine the problem that the current RX of the being in pattern of UE still is the DRX pattern.After NodeB determines the current pattern of living in of UE, can send dispatching command to this UE in any time during UE is in the RX pattern.
Below NodeB is determined that the method for the current receiving mode of living in of UE is introduced.
At least satisfy condition 5 and during one of condition 6, NodeB thinks that UE is in the RX pattern:
Condition 5:NodeB has sent uplink synchronous order or schedule information or indication to UE and has entered the order of RX pattern or the deexcitation of DRX pattern, and receives that UE correctly receives the feedback message of described order or information.Satisfying condition 5 o'clock, NodeB thinks that not only UE is in the RX pattern, and think that UE has started timer T_Inactivity_Threshold_for_UE_DRX_cycle, but send the situation of DRX pattern deexcitation order, UE does not start timer T_Inactivity_Threshold_for_UE_DRX_cycle.
Condition 6:NodeB receives the SI that UE reports, and this SI shows that UE has upstream data to be sent.
Satisfy condition 7 and during condition 8 simultaneously, NodeB thinks that UE is in the DRX pattern:
Condition 7:NodeB determines that the timer T_Inactivity_Threshold_for_UE_DRX_cycle of UE is overtime.NodeB is after learning that UE has started timer T_Inactivity_Threshold_for_UE_DRX_cycle, in the corresponding timer of NodeB side startup with described T_Inactivity_Threshold_for_UE_DRX_cycle Synchronization timeout, if this corresponding timer is overtime, then NodeB determines that the timer T_Inactivity_Threshold_for_UE_DRX_cycle of UE is overtime.For example, UE receives orders or information to the time delay to the NodeB feedback message is 20ms, UE and NodeB agreement T_Inactivity_Threshold_for_UE_DRX_cycle timing duration are 100ms, and then the timing duration of described corresponding timer is made as 80ms and can guarantees described corresponding timer and described T_Inactivity_Threshold_for_UE_DRX_cycle Synchronization timeout.
Condition 8:NodeB determines that the timer T_Inactivity_Timer_for_UE_DRX_cycle of UE is overtime.
For condition 8, if the UE side is not provided with timer T_Inactivity_Timer_for_UE_DRX_cycle, perhaps the timing duration of T_Inactivity_Timer_for_UE_DRX_cycle is 0, NodeB judge to last ACK of UE feedback at PDU in contain the 2nd SI, described the 2nd SI shows that the UE upstream data has sent and finishes that then NodeB thinks that promptly T_Inactivity_Timer_for_UE_DRX_cycle is overtime.If the UE side has started T_Inactivity_Timer_for_UE_DRX_cycle, and the timing duration of T_Inactivity_Timer_for_UE_DRX_cycle is not 0, NodeB judge to last ACK of UE feedback at PDU in contain the 2nd SI, described the 2nd SI shows that the UE upstream data has sent and finishes, then NodeB starts the corresponding timer with the T_Inactivity_Timer_for_UE_DRX_cycle Synchronization timeout, this corresponding timer is overtime, and NodeB learns that promptly T_Inactivity_Timer_for_UE_DRX_cycle is overtime.
