Abstract
A method for controlling signaling in orthogonal frequency division multiplexing technology includes that a system transmits a first monitoring period to UE (user equipment ) connected with the system in a public manner; the UE monitors page messages from a physical downlink control channel of the system within the first monitoring period; if the page messages are not monitored by the UE within the first monitoring period, the UE is set to monitor within the next monitoring period continuously; and if the page messages are monitored by the UE within the first monitoring period, the UE executes services according to the page messages. By applying the method, special signaling expense is reduced and power consumption of the integral system is further reduced.
Description
Technical field
The present invention relates to communication technical field, more specifically, relate to the control method of signaling in a kind of orthogonal frequency division multiplexi.
Background technology
The orthogonal multi-sub carrier transmission of orthogonal frequency division multiplexi (OFDM) have intersymbol interference smaller, easily expand, frequency selectivity is strong, the advantages such as dispatching flexibility.Discontinuous reception (DRX), because decreasing the time of UE monitoring control channel, adds user terminal (UE) stand-by time, is a kind of very effective power-save mechanism.
In a communications system, the DRX mechanism of UE is realized by the cooperation of multiple timer.Timer is configured to each UE by space interface signaling by base station respectively.The DRX general principle used in system as shown in Figure 1.By Active Timer (On-duration) and follow-up one section, DRX cycle may occur that the repetition period of dormancy time waits for that DRX activates (Opprtunity for DRX) and forms.
The course of work of DRX mechanism as shown in Figure 2.On-duration timer is the time period that UE searches for Physical Downlink Control Channel (PDCCH), and the continuous several PDCCH namely in a DRX cycle send subframe.In the On-duration timer term of validity, if UE receives oneself relevant correct PDCCH instruction, then receive corresponding data bag, start DRX inactivity timer (DRX-Inactivity timer) simultaneously.DRX-Inactivity timer and UE waits for the time interval again correctly receiving PDCCH instruction after correctly receiving PDCCH instruction from the last time.If DRX-Inactivity timer time-out does not correctly receive new PDCCH instruction yet, then enter DRX state, now adopt the DRX short period (Short DRX Cycle), and start DRX short cycle timer (drx-ShortCycleTimer).DRX long period (Long DRX Cycle) is then enabled after drx-ShortCycleTimer time-out.In the On-duration timer term of validity, if UE does not correctly receive oneself relevant PDCCH instruction, then enter DRX state.
Existing DRX technology can be good at the UE power saving demand met in mobile communication system.Although proprietary timer configuration mechanism is flexible, because needs configure proprietary timer for each UE, so need to send configuration messages to UE.The multiple DRX timer configuration of each UE is given this UE respectively by air interface transmission by base station, needs certain proprietary signaling consumption.Along with increasing of UE number, proprietary signaling consumption is increasing, affects whole system and runs, add the power consumption of whole system accordingly.

Embodiment
Express clearly clear for making the object, technical solutions and advantages of the present invention, below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
In embodiments of the present invention, by communication system hereinafter referred system, send same first listening period by common way to all UE.Because the listening period of all UE is consistent, system only need arrange this cycle by public mode and UE, and the signaling consumption that system is paid reduces greatly, and then lowers the power consumption of whole system.
See the control method schematic flow sheet that accompanying drawing 3 is signalings in orthogonal frequency division multiplexi, specifically comprise the following steps:
Step 301, system send the first listening period.
The first listening period is sent to the UE connected with system by common way according to system.The present invention determines a unified listening period according to the business characteristic of system and the response time demand of UE to system.In prior art, multiple UE deposits in case, needs to calculate listening period corresponding to this UE for each UE.For the situation of multiple UE, select listening period minimum in multiple UE as the first listening period, then the first listening period is sent to the UE be connected with system.First listening period is more than or equal to the time of a radio frames.Common way comprises and sends the first listening period to UE by system broadcast message.
Step 302, UE listen to beep-page message at the first listening period.
If UE listens to beep-page message in the first listening period, then perform step 303; Otherwise return step 302, namely UE continues to monitor in next first listening period.
Can divide into groups to UE, the first listening period often organized is all identical, but different issuing of DRX of group is not issue simultaneously, and the issuing of DRX of each group is staggered in time.See accompanying drawing 4, UE is divided into two groups, the DRX intermittent often organized issues.Accordingly, the UE of first group monitors from the beep-page message of system according to the first listening period at synchronization; The UE of second group also monitors beep-page message from system according to the first listening period at synchronization.The UE of first group monitors in the different moment from the UE of second group.
The advantage of UE grouping is: the corresponding increase of UE number that can be paged in the unit interval, improves the performance of scheduling, saves terminal electric power simultaneously.
In addition, can also issue DRX to all UE, so all UE monitor the beep-page message from system at the first listening period synchronization simultaneously.
Step 303, UE perform business according to beep-page message.
UE carries out relevant business according to beep-page message.
After being connected with system, Sleep state is namely in see accompanying drawing 5, UE.After this UE monitors beep-page message according to the first listening period T1.After UE listens to the message of paging oneself, proceed to Active state, monitoring PDCCH message time is continuously T1.If UE is not scheduled in T1, namely do not receive the PDCCH Indication message relevant to oneself, then continue to enter Sleep state.
If UE is scheduled within the T1 time period, then start to carry out business data transmission process, this process is by relevant to business practical implementation for time T2, the T2 duration that continues to be scheduled.
Send after DCI indicates stopping business transmitting procedure when UE receives system, UE also still monitors PDCCH message continuously in the second listening period T3.If UE is scheduled in T3, then continue business transmission.If UE is not scheduled in T3, then UE enters Sleep state.T3 is determined by high-priority users frame.Such as, if most of high-priority users can pass defeated substantially in n frame, then T3 has been n frame, and after n frame, UE continues to keep accepting state, waits for descending control.
As shown in Figure 6, for the UE arrived paged in the first listening period, the follow-up scheduling of active state waiting system is entered.(receive DCI instruction and terminate scheduling) after UE service ending, UE will continue to monitor PDCCH in the second listening period.If in the second listening period, UE is not scheduled again, then enter sleep state, if in the second listening period, UE is scheduled again, then continue finishing service transmission.For not paged UE, continue sleep state and wait for that the monitoring moment next time arrives.
The several moment shown for UE, Fig. 7 are crucial moments that the state of UE changes.First, in the first listening period, UE monitors the moment t of beep-page message
1if listening to the beep-page message of system to oneself, then UE enters Active state from Sleep state, namely monitors the state of PDCCH continuously.
Next is the moment t receiving PDCCH Indication message
2, UE starts to carry out business transmitting procedure under Active state, enters the sub-state of activation of service under Active state.
Receive the moment t that DCI indicating services terminates again
3although UE business procedure stops, but still monitor PDCCH Indication message continuously in the second listening period, the scheduling to UE can be recovered when to guarantee that system carries out business time-out to UE in time, i.e. the follow-up listening state of PDCCH under Active state.
Finally the moment t that UE terminates to monitor PDCCH message
4if, in the continuous snoop procedure of the PDCCH in the second listening period, until t
4moment arrives, and UE does not listen to self PDCCH Indication message, then can enter Sleep state.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
