Description

A kind of method and device monitoring Physical Broadcast Channel
Technical field
The present invention relates to wireless communication technology field, especially relate to a kind of method, the Apparatus and system of monitoring Physical Broadcast Channel (PBCH, Physical Broadcast Channel).
Background technology
At Long Term Evolution (LTE; Long Term Evolution) in communication system; as the TDD(Time division duplex of one of two large basic duplex systems; time division duplex) pattern; refer to that uplink downlink uses same working band; the different time intervals carries out the transmission of uplink and downlink signals, between downstream transmission, has protection interval (Guard Period, GP).
The frame structure of LTE TDD system, as shown in Figure 1, a radio frames length is 10ms, and comprise special subframe and conventional subframe two class, totally 10 subframes, each subframe is 1ms.Common subframe is made up of the time slot of two 0.5ms, special subframe is divided into 3 time slots: descending pilot frequency time slot (DwPTS, Downlink Pilot Slot), for transmitting master sync signal (PSS, Primary Synchronization Signal), Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel), physical mixed automatic repeat request indicating channel (PHICH, Physical HARQ Indication Channel), Physical Control Format Indicator Channel (PCFICH, Physical Control Format Indication Channel), physical down link sharing channel (PDSCH, Physical Downlink Shared Channel) etc., GP is used for the protection interval between descending and uplink, uplink pilot time slot (UpPTS, Uplink Pilot Slot), for transmitting detection reference signal (SRS, Sounding Reference Signal), Physical Random Access Channel (PRACH, Physical Random Access Channel) etc.Conventional subframe comprises sub-frame of uplink and descending sub frame, for transmitting uplink/downlink control channel and business datum etc.
LTE TDD time resource distributes on up-downlink direction.As shown in table 1, the up-downgoing time scale that tdd frame structural support 7 kinds is different distributes (configuration 0 ~ 6 as shown in table 1).Can be configured according to the characteristic of traffic carrying capacity.These 7 kinds different up-downgoing time scale configurations comprise the situation in 3 kinds of 5ms cycles and 4 kinds of 10ms cycles.In the configuration in 5ms cycle, every 5ms comprises the conversion interval of a downstream-to-upstream; And in the period assignment of 10ms, every 10ms comprises the conversion interval of a downstream-to-upstream.Concrete configuration is as shown in table 1, and wherein " D " represents descending sub frame, and " U " is expressed as sub-frame of uplink, and " S " is expressed as the special subframe comprising conversion interval.
Table 1
TDD up-downgoing time scale assignment information (also can be referred to as TDD proportioning) is included in the system information block (SIB of system broadcast message, System Information Block) in, user terminal (UE, User Equipment) is sent to by broadcast.For the UE in same overlay area, by reading broadcast, obtain identical up-downgoing time scale assignment information.For realizing real-time adjusting flexibly TDD up-downgoing time scale assignment information according to different business, reducing the time delay that UE carries out data processing, increasing throughput of system, in prior art, propose following two kinds of technical schemes:
The first scheme: by needing the UE carrying out the adjustment of TDD up-downgoing time scale assignment information to send wireless heterogeneous networks (RRC, Radio Resource Control) proprietary message, notify UE TDD up-downgoing time scale assignment information.Wherein, the new TDD up-downgoing time scale assignment information in the proprietary message of RRC after subsidiary change.The defect of this kind of scheme is that needing to send the proprietary message of RRC to each UE notifies, makes signaling consumption increase.
First scheme: by sending beep-page message to the UE needing to carry out the adjustment of TDD up-downgoing time scale assignment information, beep-page message instruction UE, in next one amendment cycle receiving system information, still comprises the new TDD up-downgoing time scale assignment information after change in system message.UE by paging receiving message, and regains system message, knows the SIB1 message of the TDD up-downgoing time scale assignment information that have changed, thus obtains new TDD up-downgoing time scale assignment information.It is long that the defect of this kind of scheme is to make UE obtain new TDD up-downgoing time scale assignment information time delay because the change of existing system message is machine-processed.
For the defect that above-mentioned two kinds of technical schemes exist, a kind of solution is proposed: by using Master Information Block (MIB in system broadcast message in prior art, Master Information Block) 3 reserved bit indicate TDD up-downgoing time scale assignment information, for supporting that the novel UE of the flexible proportioning of TDD can change the TDD up-downgoing time scale of oneself in time.Such as 000 to represent TDD up-downgoing proportional arrangement be that 0,010 to represent up-downgoing proportional arrangement be 2 etc.Because MIB mapping sends in Physical Broadcast Channel, and the transmission cycle is 40ms.In UE side, UE needs every 40ms to monitor PBCH, obtains the mib information transmitted in PBCH, then knows new TDD up-downgoing time scale assignment information according to the reserved bit position of the mib information obtained.Under this mode, UE needs frequently to monitor PBCH with the set time, and the flexibility of monitoring PBCH is poor, and the mib information transmitted in the monitoring PBCH continued, also make the electric quantity consumption of UE larger.

Embodiment
Need frequently to monitor PBCH with the set time for the UE proposed in prior art, to obtain the TDD up-downgoing time scale assignment information that network side is issued, make the flexibility of monitoring PBCH poor, and the mib information transmitted in the monitoring PBCH continued, also the problem that the electric quantity consumption of UE is larger is made, the technical scheme that the embodiment of the present invention proposes here, network side determination listening period indication information, the listening period indication information determined shoulder to shoulder sends to UE, UE monitors PBCH according to the listening period indication information received, and then obtain TDD up-downgoing time scale assignment information, PBCH is monitored at specific time point by configuration UE, UE does not need frequently to monitor PBCH, only need to monitor PBCH according to the time of listening period indication information instruction, thus UE can be made to monitor PBCH flexibly with while obtaining TDD up-downgoing pro rate information, reduce the electric quantity consumption of UE self.
Below in conjunction with each accompanying drawing, the main of embodiment of the present invention technical scheme is realized principle, embodiment and set forth in detail the beneficial effect that should be able to reach.
Embodiment one
The embodiment of the present invention one proposes to monitor PBCH system in a kind of TDD system here, and this system comprises network side and end side, mainly comprises the network element devices such as base station, evolved base station, radio network controller, mainly comprise UE in end side at network side.The UE that wherein end side comprises can be, but not limited to be divided into two kinds, and one is traditional UE, namely can receive the broadcast comprising SIB that network side issues, and comprises TDD up-downgoing time scale assignment information in SIB.UE possesses the UE that can receive the TDD up-downgoing time scale assignment information that network side issues flexibly on the function basis with traditional UE, namely has the UE of the flexible proportioning function of TDD.
Network side is used for determining listening period indication information, and the listening period indication information determined is sent to UE, UE then monitors PBCH according to the listening period indication information received, and then obtains new TDD up-downgoing proportional arrangement information by the reserved bit position of reading the mib information received.
Based on said system framework, the embodiment of the present invention one proposes a kind of method monitoring PBCH here, and as described in Fig. 2 a, its handling process is specific as follows to be stated:
Step 21, determines listening period indication information.
Can be, but not limited to determine listening period indication information by RRC information, MAC CE or beep-page message.Wherein, determining that the implementation of listening period indication information can be, but not limited to is following several mode:
First kind of way: instruction UE is monitored time of PBCH with the transmission cycle of the MIB transmitted in PBCH as reference, determine listening period indication information.
Under this kind of mode, each MIB that can transmit in PBCH sends the time in cycle as listening period indication information, instruction UE monitors PBCH in each MIB transmission cycle, to obtain the new TDD up-downgoing time scale assignment information carried in the reserved bit position of MIB.Such as, suppose that the transmission cycle of each MIB is 40ms, then, under this kind of mode, the every 40ms of UE can be indicated just to monitor a PBCH.Namely start to monitor PBCH when 0ms, 40ms, 80ms.
Preferably, can to transmit the temporal information of at least two MIB in PBCH, as listening period indication information.
Such as, listening period instruction UE being monitored PBCH is configured to the transmission cycle of every N number of MIB, and wherein N is more than or equal to 2.As N=1, then represent that UE each MIB transmission cycle needs to monitor PBCH, compare the electricity of waste UE.The embodiment of the present invention one is here with N=2, a transmission cycle of MIB is 40ms is that example is described in detail, then indicate UE at 0ms, 80ms, 160ms ... in time, starts to monitor PBCH, to obtain the new TDD up-downgoing time scale assignment information carried in the reserved bit position of MIB.
In mib information, comprise System Frame Number (SFN, the System Frame Number) indication information of 8, can indicate 256 numerical value, 6 Physical Resource Block (PRB, Physical Resource Block) in the middle of band occupancy send.But the time of SFN comes to 1024ms, therefore need 40ms could indicate once, namely every 40ms sends one is that every 40ms sends a mib information.In this 40ms, what every 10ms sent is redundancy versions, and namely identical information adopts different modulation coding modes or channel to send, to ensure after 40ms integral multiple, the UE of access can obtain this information, simultaneously by merging the reliability receiving and also can improve data receiver.Based on this, UE, after receiving listening period indication information, according in the time of listening period indication information instruction, can at least monitor a PBCH in each MIB transmission cycle.The transmission cycle supposing MIB is 40ms, and monitoring instruction time is that every two MIB send the cycle, and namely 80ms monitors PBCH, then UE can in the 40msMIB transmission cycle after the transmission cycle 80ms of two MIB, PBCH is monitored once, or monitors repeatedly, to guarantee the reliability of receives information.Therefore, the cycle can be sent as a reference with N*MIB, deviant Offset is set.By N value and the Offset value of setting, determine listening period indication information.Namely UE is indicated to send at N*MIB the time monitoring PBCH that cycle+Offset*MIB sends the cycle.Namely indicate UE after receiving listening period indication information, according in the time of listening period indication information instruction, can at least monitor a PBCH in each MIB transmission cycle.Such as, when the transmission cycle supposing each MIB is 40ms, N=2, Offset=0, UE can at 0ms, 80ms, 160ms ... in time, starts to monitor PBCH; When N=2, Offset=1, UE can at 40ms, 120ms, 200ms ... in time, starts to monitor PBCH.Namely UE is indicated at interval of in the time of at least two MIB, at least can to monitor a PBCH.Such UE does not need frequently to monitor PBCH, improves the flexibility of monitoring PBCH, and UE only monitors PBCH in the time of listening period indication information instruction, can save the electric quantity consumption of UE self preferably.
The second way: by discontinuous reception (DRX, Discontinuous Reception) activationary time, determine listening period indication information.
When UE is in DRX state, using all or part of DRX activationary time information as listening period indication information.
In existing standard, define the DRX configuration rule for UE, UE only monitors Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) between DRX active period, does not monitor PDCCH at inactive period UE.But for when monitoring PBCH, existing standard does not make relevant regulations.UE can as required, monitor PBCH at any time, and namely no matter UE is between DRX active period, and be still in DRX inactive period, UE may monitor PBCH.Based on this, in the technical scheme that the embodiment of the present invention one proposes here, when configuration UE is in DRX state, using all or part of DRX activationary time as listening period indication information, namely UE is only between the active period of DRX, PBCH is monitored, and then obtains TDD up-downgoing time scale assignment information.
Such as, UE can need to monitor PBCH in DRX activationary time, or UE monitors PBCH in (part activationary time) during DRX On duration, or UE monitors PBCH etc. in the activationary time except during DRX OnDuration.Like this, due to being in DRX inactivation time, do not need data and the business of transmission, therefore UE does not need to monitor PBCH, improves the flexibility of monitoring PBCH further, and then can save the power consumption of UE preferably.
Preferably, in concrete enforcement, the above-mentioned second way can be combined with first kind of way, namely indicates UE between DRX active period, sends the cycle for interval, monitor PBCH with N number of MIB.Such as, supposing that MIB sends the cycle is 40ms, N=2, then indicate UE between DRX active period, can at 80ms, 160ms ... time monitor PBCH.
The third mode: in conjunction with the transmission cycle of MIB and the activationary time of DRX, determine listening period indication information.
When UE enters DRX state of activation, then using all or part of DRX activationary time as listening period indication information, then UE need DRX be in state of activation start after a period of time can obtain new TDD up-downgoing time scale assignment information.Namely as shown in Figure 2 b, the time of UE monitoring PBCH and DRX activationary time be not on same start time point, based on this, the invention process one proposes at least one MIB that comprises before DRX activationary time to send the temporal information in cycle as listening period indication information here.Particularly, when configuration UE is in DRX state, determine DRX activationary time information, using the fixed time information in the time before the DRX activationary time information determined as listening period indication information, fixed time information is the transmission cycle time information of at least one MIB.Such as, UE M MIB before DRX activationary time can be indicated to send time corresponding to cycle and start to monitor PBCH, wherein M is positive integer, M=1,2,3 ...
As shown in Figure 2 b, what adopt the embodiment of the present invention one to propose here sends the temporal information in cycle as listening period indication information using at least one MIB that comprises before DRX activationary time, can ensure preferably UE monitor PBCH time time point and DRX activationary time on same start time point, like this, before UE enters DRX state of activation, just obtain up-to-date TDD up-downgoing time scale assignment information by monitoring PBCH, the up-to-date TDD up-downgoing time scale assignment information of acquisition can be used to carry out the transmitting-receiving of data, and then transfer of data can be carried out according to up-to-date TDD up-downgoing proportional time after making UE enter DRX state of activation.
Preferably, the third mode above-mentioned can be combined with above-mentioned first kind of way or the second way.Such as, when being combined with first kind of way, setting UE M MIB before DRX activationary time sends after time corresponding to cycle starts to monitor PBCH, then monitors PBCH with the interval time at least M MIB transmission cycle.Suppose M=2, each MIB transmission cycle is 40ms, DRX activationary time is K, then, when being combined with first kind of way, with in a period of time before DRX activationary time K, monitor a PBCH according to every 80ms; When being combined with the above-mentioned second way, UE M MIB before DRX activationary time sends after time corresponding to cycle starts to monitor PBCH, cycle monitoring PBCH is sent with M MIB again between DRX active period, suppose M=2, the transmission cycle of each MIB is 40ms, then, when being combined with the above-mentioned second way, UE M MIB before DRX activationary time sends after time corresponding to cycle starts to monitor PBCH, between DRX active period, monitor PBCH with the time of 80ms.
4th kind of mode: send the time of service data information or traffic scheduling solicited message as a reference with UE, determine listening period indication information.
The time of service data information or traffic scheduling solicited message can be sent as listening period indication information using UE; Or using the temporal information of UE being carried out to traffic scheduling as listening period indication information.
Preferably, the 4th kind of mode can be used alone, and also can determine that listening period indication information performs simultaneously with above-mentioned three kinds.Using the 4th kind of mode as the constraints of aforementioned three kinds of modes, determine listening period indication information.Lift an example to be described: for first kind of way, to the time of UE monitoring PBCH be indicated with the transmission cycle of the MIB transmitted in PBCH as reference, determine listening period indication information, this kind of mode and the 4th kind of mode are combined, be about to instruction UE and monitor the time of PBCH with the transmission cycle of the MIB transmitted in PBCH, and send the time of service data information or traffic scheduling solicited message in the lump as determining condition with UE, determine listening period indication information.Suppose that the transmission cycle of MIB is 40ms, according to first kind of way, can using the transmission cycle of two MIB and 80ms as listening period indication information, and then UE can be sent the time of service data information or traffic scheduling solicited message as constraint, although namely using 80ms as listening period indication information, but UE does not send service data information or traffic scheduling solicited message to network side, then UE also can not monitor PBCH.Can specify that UE monitors the time of PBCH so further, improve the flexibility that UE monitors PBCH.
Similarly, the 4th kind of mode is also identical constraint principles for the above-mentioned second way and the third mode, repeats no longer one by one here.
5th kind of mode: to carry out the temporal information of traffic scheduling as a reference to UE, determine listening period indication information.
Particularly, can to carry out the temporal information of traffic scheduling to UE as listening period indication information.Preferably, can with by down physical channel to UE send traffic scheduling instruction temporal information, as listening period indication information.Wherein, down physical channel can be, but not limited to be the down physical channel EPDCCH of PDCCH or enhancing.
Correspondingly, 5th kind of mode can singly be not limited to be used alone, also can with above-mentioned the first ~ the third mode is combined, by the 5th kind of mode as above-mentioned the first ~ constraints of the third mode, with above-mentioned three kinds, mode B can determine that listening period indication information performs simultaneously.
Lift an example to illustrate: for first kind of way, to the time of UE monitoring PBCH be indicated with the transmission cycle of the MIB transmitted in PBCH as reference, determine listening period indication information, with the 5th kind of mode be first kind of way be constrained to example to be described in detail, instruction UE is monitored the time of PBCH with the transmission cycle of the MIB transmitted in PBCH, with UE is carried out to the temporal information of traffic scheduling as determining condition, determine listening period indication information further.Whether the time such as determining the transmission cycle of at least two MIB transmitted in PBCH is the temporal information of UE being carried out to traffic scheduling, if not, although the time in the transmission cycle of at least two MIB transmitted in PBCH is sent to UE as listening period indication information, whether this time is still by being do further constraint to the temporal information that UE carries out traffic scheduling.After UE receives and monitors instruction time, only when being carried out traffic scheduling by network side, just monitor PBCH, to obtain up-to-date TDD up-downgoing time scale assignment information according to the transmission periodic region of at least two MIB.
Similarly, the 5th kind of mode is also identical constraint principles for the above-mentioned second way and the third mode, repeats no longer one by one here.
6th kind of mode: to send the time of feedback information as a reference, determine listening period indication information.
Can to send the time of feedback information as listening period indication information to UE, wherein, feedback information is after receiving the service data information or traffic scheduling solicited message that UE sends, to the information receiving service data information or traffic scheduling solicited message that UE sends.
In this kind of mode, can be, but not limited to be used alone, also can use as the constraints of above-mentioned first ~ the third mode, determine listening period indication information.Such as, be combined as example is described in detail with this kind of mode in the first manner: determine that whether the time in the transmission cycle of at least two MIB transmitted in PBCH be the network side determined sends time from feedback information to UE, if not, although the time in the transmission cycle of at least two MIB transmitted in PBCH is sent to UE as listening period indication information, whether this time is still by being the time that the network side determined sends feedback information to UE do further constraint.After UE receives and monitors instruction time, in the time sending feedback information to UE only determined at network side arrives, just monitor PBCH, to obtain up-to-date TDD up-downgoing time scale assignment information according to the transmission periodic region of at least two MIB.
Preferably, before determining listening period indication information, also comprise: receive the measurement result measured the reference signal transmitted in reference channel that UE reports, reference signal is used to indicate downlink data synchronous transmission, according to the measurement result received, determine listening period indication information.
Wherein, reference signal can be, but not limited to comprise cell reference signals (CRS, Cell Reference Signal), sparse cell reference signals (Reduced CRS), channel state information reference signals (CSI RS, Channel State Information Reference Signal), demodulated reference signal (DMRS, Demodulation Reference Signal) etc.
If be configured with DRX function to UE, preferably, measurement and synchronous can be carried out in N number of cycle reference signal of configuration UE before DRX activationary time, and receive the measurement result that UE reports.When DRX is in state of activation, UE can obtain down-going synchronous and send immediately and carry out measuring the measurement result obtained for those reference signals, such as channel quality instruction (CQI, Channel Quality Indication) and obtain down-going synchronous etc.Like this, network side can be made to obtain correlation measurements in time, carry out the operations such as follow-up data scheduling in time.
Step 22, sends to UE by the listening period indication information determined, monitors PBCH with the time making UE indicate according to listening period indication information.
The listening period indication information determined is sent to UE, UE can monitor PBCH according to the time of the monitoring indication information instruction received, thus obtain the MIB transmitted in PBCH, and determine TDD up-downgoing time scale assignment information in 3 reserved bit positions of MIB, like this, UE can change the TDD up-downgoing time scale configuration of self in time.

Embodiment two
The embodiment of the present invention two proposes a kind of method monitoring PBCH here, and as shown in Figure 5, its concrete handling process is as following:
Step 51, receives the listening period indication information that network side is sent.
Network side can be, but not limited to be receive by modes such as RRC information, MAC CE or beep-page messages the listening period indication information that network side determines.
Step 52, according to the listening period indication information received, monitors PBCH.
Wherein, in the concrete enforcement of this step 52, can be, but not limited to comprise following several mode:
First kind of way: with the transmission cycle of the MIB transmitted in PBCH as reference, monitors PBCH.
The transmission cycle of the MIB transmitted in PBCH is comprised in listening period indication information.In UE side, this transmission cycle is also the receiving cycle that UE receives MIB, under this kind of mode, each MIB that can transmit in PBCH sends the time in cycle as listening period, UE monitors PBCH at each MIB receiving cycle, to obtain the new TDD up-downgoing time scale assignment information carried in the reserved bit position of MIB.Such as, suppose that the transmission cycle of each MIB is 40ms, then, under this kind of mode, the listening period indication information that UE can send according to network side, every 40ms just monitors a PBCH.Namely start to monitor PBCH when 0ms, 40ms, 80ms.
Preferably, when UE can transmit the temporal information of at least two MIB in PBCH, monitor PBCH.
Monitoring the frequency of PBCH for reducing UE, reducing the electric quantity consumption of UE, UE can monitor PBCH with the transmission cycle of at least N number of MIB in interval.Wherein N is more than or equal to 2.As N=1, then represent that UE each MIB transmission cycle needs to monitor PBCH, the relatively electricity of waste UE, suppose N=2, the transmission cycle of each MIB is 40ms, then UE can at 0ms, 80ms, 160ms ... in time, starts to monitor PBCH, to obtain the new TDD up-downgoing time scale assignment information carried in the reserved bit position of MIB.
In mib information, comprise the SFN indication information of 8, can indicate 256 numerical value, 6 PRB in the middle of band occupancy send.But the time of SFN comes to 1024ms, therefore need 40ms could indicate once, namely every 40ms sends a mib information, and that is the transmission cycle of MIB is 40ms.In this 40ms, what every 10ms sent is redundancy versions, and namely identical information adopts different modulation coding modes or channel to send, and to ensure after 40ms integral multiple, enables the UE of period access obtain this information, also improves the reliability of data receiver simultaneously.
Therefore, the cycle can be sent as a reference with N*MIB, deviant Offset is set.UE passes through N value and the Offset value of setting, monitors PBCH.Namely UE sends at N*MIB the time monitoring PBCH that cycle+Offset*MIB sends the cycle.
Such as, when the transmission cycle supposing each MIB is 40ms, N=2, Offset=0, UE can at 0ms, 80ms, 160ms ... in time, starts to monitor PBCH; When N=2, Offset=1, UE can at 40ms, 120ms, 200ms ... in time, starts to monitor PBCH.Namely UE at interval of in the time of at least two MIB, at least can monitor a PBCH.UE, after receiving listening period indication information, according in the time of listening period indication information instruction, can at least monitor a PBCH in each MIB transmission cycle.Such as, the time of listening period indication information instruction starts to monitor at every two MIB transmission cycle, namely just start to monitor PBCH every 80m, suppose when 160ms, UE monitors PBCH, further, for ensureing the reliability of data receiver, during 160 ~ 200ms, UE at least monitors a PBCH, and such as UE can monitor a PBCH when 160ms, then monitors a PBCH again when 180ms, by that analogy, thus obtain in PBCH the new TDD up-downgoing time scale assignment information carried in reserved bit position in the mib information transmitted.
The second way: with DRX activationary time for reference, monitors PBCH according to the listening period indication information received.
When UE is in DRX state, in all or part of DRX activationary time, monitor PBCH.
In existing standard, define the DRX configuration rule for UE, UE only monitors PDCCH between DRX active period, does not monitor PDCCH at inactive period UE.But for when monitoring PBCH, existing standard does not make relevant regulations.UE can as required, monitor PBCH at any time, and namely no matter UE is between DRX active period, and be still in DRX inactive period, UE may monitor PBCH.Based on this, in the technical scheme that the embodiment of the present invention two proposes, comprise DRX activationary time at the listening period indication information received here, when UE is in DRX activation, monitor PBCH with all or part of DRX activationary time, and then obtain TDD up-downgoing time scale assignment information.Such as, UE can need to monitor PBCH in DRX activationary time, or UE monitors PBCH in (part activationary time) during DRX On duration, or UE monitors PBCH etc. in the activationary time except during DRX OnDuration.Due to being in DRX inactivation time, do not need data and the business of transmission, therefore UE does not need to monitor PBCH, can reduce the power consumption of UE preferably.
Preferably, in concrete enforcement, the above-mentioned second way can be combined with first kind of way, and namely UE is between DRX active period, sends the cycle for interval, monitor PBCH with N number of MIB.Such as, supposing that MIB sends the cycle is 40ms, N=2, then UE is between DRX active period, can at 80ms, 160ms ... time monitor PBCH.
The third mode: in conjunction with the transmission cycle of MIB and the activationary time of DRX, monitors PBCH.
DRX activationary time and MIB transmission cycle is included in the listening period indication information that the network side received is sent, when UE is in discontinuous reception DRX state, determine DRX activationary time information, in fixed time in time before the DRX activationary time information determined, monitor PBCH, described fixed time information is the transmission cycle time information of at least one MIB.Such as, UE can M MIB send time corresponding to cycle and starts to monitor PBCH before DRX activationary time, and wherein M is positive integer, M=1,2,3 ...
Wherein, in conjunction with transmission cycle of MIB and DRX activationary time as a reference, in the monitoring indication information received, comprise the transmission cycle of the MIB transmitted in PBCH, UE can send time in cycle by least one MIB that comprises before DRX activationary time, starts to monitor PBCH.When UE enters DRX state of activation, again using all or part of DRX activationary time as listening period indication information, then UE need DRX be in state of activation start after a period of time can monitor PBCH, the time of UE monitoring PBCH and DRX activationary time be not on same start time point, based on this, in the technical scheme that the embodiment of the present invention two proposes here, the time comprising at least one MIB transmission cycle before DRX activationary time is started to monitor PBCH.Can ensure preferably like this UE monitor PBCH time time point and DRX activationary time on same start time point, like this, after UE enters DRX state of activation, PBCH can be monitored at once and obtain up-to-date TDD up-downgoing time scale assignment information, and use the up-to-date TDD up-downgoing time scale assignment information obtained to carry out the transmitting-receiving of data, and then after making UE enter DRX state of activation, the up-to-date TDD up-downgoing time scale assignment information that network side issues can adapt to the data of business.
Preferably, the third mode above-mentioned can be combined with above-mentioned first kind of way or the second way.Such as, when being combined with first kind of way, UE M MIB before DRX activationary time sends after time corresponding to cycle starts to monitor PBCH, then monitors PBCH with the interval time at least M MIB transmission cycle; When being combined with the above-mentioned second way, UE M MIB before DRX activationary time sends after time corresponding to cycle starts to monitor PBCH, then monitors PBCH between DRX active period.Particularly, the third mode above-mentioned can refer to elaborating in above-described embodiment one with elaborating of being combined of above-mentioned first kind of way or the second way, and the embodiment of the present invention two repeats no more here.
