Description

A kind of method and device for monitoring Physical Broadcast Channel
Technical field
The present invention relates to wireless communication technology field, more particularly, to a kind of monitoring Physical Broadcast Channel (PBCH, Physical Broadcast Channel) method, apparatus and system.
Background technique
In long term evolution (LTE, Long Term Evolution) communication system, as two big basic duplex systems it One TDD(Time division duplex, time division duplex) mode, refer to that uplink downlink uses the same working band, The transmission for carrying out uplink and downlink signals on interval in different times, have between downstream transmission protection interval (Guard Period, GP).
The frame structure of LTE TDD system, as shown in Figure 1, a wireless frame length is 10ms, it include special subframe and routine Two class of subframe, totally 10 subframes, each subframe are 1ms.Common subframe is made of the time slot of two 0.5ms, and special subframe is divided into 3 A time slot: descending pilot frequency time slot (DwPTS, Downlink Pilot Slot) is used for transmission primary synchronization signal (PSS, Primary Synchronization Signal), Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel), physical mixed automatic repeat request indicates 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 Protection interval between downlink and uplink transmission；Uplink pilot time slot (UpPTS, Uplink Pilot Slot), is used for transmission Detection reference signal (SRS, Sounding Reference Signal), Physical Random Access Channel (PRACH, Physical Random Access Channel) etc..Conventional subframe includes sub-frame of uplink and downlink subframe, is used for transmission uplink/downlink control Channel and business datum etc..
LTE TDD time resource is allocated on up-downlink direction.As shown in table 1,7 kinds of differences of tdd frame structural support Uplink and downlink time scale distribution (as shown in table 1 configure 0~6).It can be configured according to the characteristic of portfolio.This 7 The different uplink and downlink time scale configuration of kind includes the case where 3 kinds of 5ms periods and 4 kinds of 10ms periods.In the configuration in 5ms period In, every 5ms includes the conversion interval of a downstream-to-upstream；And in the period assignment of 10ms, every 10ms includes a downlink To the conversion interval of uplink.Concrete configuration is as shown in table 1, wherein " D " indicates downlink subframe, " U " is expressed as sub-frame of uplink, " S " It is expressed as the special subframe comprising conversion interval.
Table 1
TDD uplink and downlink time scale distributes information (can also be referred to as TDD proportion) It unites in block of information (SIB, System Information Block), user terminal (UE, User is sent to by broadcast message Equipment).For the UE in the same overlay area, is broadcast the message by reading, obtain identical uplink and downlink time scale Distribute information.To realize that distributing information to TDD uplink and downlink time scale according to different business in real time is adjusted flexibly, and subtracts Small UE carries out the time delay of data processing, increases throughput of system, proposes following two kinds of technical solutions in the prior art:
The first scheme: by sending wireless money to the UE for needing to carry out the distribution information adjustment of TDD uplink and downlink time scale Source controls (RRC, Radio Resource Control) proprietary message, and notice UE TDD uplink and downlink time scale distributes information. Wherein, the new TDD uplink and downlink time scale after incidentally changing in the proprietary message of RRC distributes information.The defect of this kind of scheme It is to need to send the proprietary message of RRC to each UE to notify, so that signaling overheads increases.
Second scheme: disappeared by sending paging to the UE for needing to carry out the distribution information adjustment of TDD uplink and downlink time scale Breath, paging message indicate that UE receives system information in next modification period, include new after changing still in system message TDD uplink and downlink time scale distributes information.UE and regains system message by receiving paging message, knows and has changed TDD uplink and downlink time scale distributes the SIB1 message of information, to obtain new TDD uplink and downlink time scale distribution information.It should The defect of kind scheme is that mechanism is changed due to existing system message makes UE obtain new TDD uplink and downlink time scale distribution information Time delay is long.
For defect existing for above two technical solution, a kind of solution is proposed in the prior art: by using being 3 reserved bits of Master Information Block (MIB, Master Information Block) indicate TDD or more in system broadcast message Row time scale distributes information, and the novel UE for supporting TDD flexibly to match can change the TDD uplink and downlink time of oneself in time Ratio.Such as 000 to represent TDD uplink and downlink proportional arrangement be 0,010 to represent uplink and downlink proportional arrangement as 2 etc..Since MIB mapping is It is sent in Physical Broadcast Channel, and sending cycle is 40ms.In the side UE, UE needs every 40ms to monitor PBCH, obtains Then the mib information transmitted in PBCH knows new TDD uplink and downlink time ratio according to the reserved bit position of the mib information of acquisition Example distribution information.Under this mode, UE needs frequently to monitor PBCH with the set time, and the flexibility for monitoring PBCH is poor, and And the mib information transmitted in lasting monitoring PBCH, but also the electric quantity consumption of UE is larger.

For example, configuring the sending cycle per N number of MIB for the listening period for indicating UE monitoring PBCH, wherein N is more than or equal to 2.As N=1, then it represents that each MIB sending cycle of UE requires to monitor PBCH, the electricity of more wasteful UE.The embodiment of the present invention One here with N=2, and a sending cycle of MIB is described in detail for being 40ms, then indicate UE 0ms, 80ms, PBCH is begun listening for when 160ms ..., to obtain the new TDD uplink and downlink time scale carried in the reserved bit position of MIB Distribute information.
System Frame Number (SFN, System Frame Number) in mib information comprising 8 indicates information, can refer to Show 256 numerical value, 6 Physical Resource Block (PRB, Physical Resource Block) among band occupancy are sent. But the time of SFN comes to 1024ms, it is therefore desirable to which 40ms could indicate that once that is, every 40ms sends i.e. every 40ms hair Send a mib information.In this 40ms, what every 10ms was sent is redundancy versions, i.e., identical information uses different modulating-codings Mode or channel are sent, and to guarantee after 40ms integral multiple, the UE of access can obtain the information, while be connect by merging Receive the reliability that can also be improved data receiver.Based on this, UE, can be according to monitoring after receiving listening period instruction information Time indicates at least to monitor a PBCH in each MIB sending cycle in the time of information instruction.Assuming that the transmission week of MIB Phase is 40ms, and monitoring the instruction time is every two MIB sending cycle, i.e. 80ms monitors PBCH, then UE can be in the hair of two MIB It send in the 40msMIB sending cycle after period 80ms, PBCH is monitored primary, or monitor repeatedly, to ensure that information receives Reliability.Therefore, deviant Offset can be set using N*MIB sending cycle as reference.By the N value of setting and Offset value determines that listening period indicates information.I.e. instruction UE N*MIB sending cycle+Offset*MIB sending cycle when Between monitor PBCH.That is instruction UE can indicate information instruction after receiving listening period instruction information according to listening period In time, a PBCH is at least monitored in each MIB sending cycle.For example, it is assumed that the sending cycle of each MIB is 40ms, N When=2, Offset=0, PBCH is begun listening for when UE can be in 0ms, 80ms, 160ms ...；When N=2, Offset=1, UE can be with PBCH is begun listening for when in 40ms, 120ms, 200ms ....I.e. instruction UE can in the time at interval of at least two MIB, At least monitor a PBCH.UE in this way does not need frequently to monitor PBCH, improves the flexibility for monitoring PBCH, and UE is only being monitored Time indicates that the time of information instruction monitors PBCH, can preferably save the electric quantity consumption of UE itself.
The second way: by discontinuous reception (DRX, Discontinuous Reception) activationary time, prison is determined The time is listened to indicate information.
When UE is in DRX state, information is indicated using all or part of DRX activationary time information as listening period.
, it is specified that DRX configuration rule for UE, UE is only to physical down control during DRX activation in existing standard Channel (PDCCH, Physical Downlink Control Channel) processed is monitored, and is not listening in inactive period UE PDCCH.But PBCH is monitored for when, existing standard does not make relevant regulations.UE can according to need, right at any time PBCH is monitored, i.e., no matter UE is to be in DRX inactive period, UE may be to PBCH in during DRX activation It is monitored.Based on this, in one technique proposed herein scheme of the embodiment of the present invention, when configuration UE is in DRX state, with complete As listening period instruction information, i.e. UE only during the activation of DRX, monitors PBCH for portion or part DRX activationary time, And then it obtains TDD uplink and downlink time scale and distributes information.
For example, UE can need to monitor in DRX activationary time the (portion during DRX On duration PBCH or UE Shunt excitation live time) in monitor PBCH or UE PBCH etc. is monitored in the activationary time in addition to during DRX OnDuration.This Sample, due to being in DRX inactivation time, the data and business of transmission not in need, therefore UE does not need to monitor PBCH, The flexibility for monitoring PBCH is further increased, and then can preferably save the power consumption of UE.
Preferably, in specific implementation, the above-mentioned second way can be used in combination with first way, i.e. instruction UE exists During DRX is activated, using N number of MIB sending cycle as interval, PBCH is monitored.For example, it is assumed that MIB sending cycle be 40ms, N=2, then Indicate that UE during DRX activation, monitors PBCH when can be in 80ms, 160ms ....
The third mode: in conjunction with the sending cycle of MIB and the activationary time of DRX, to determine that listening period indicates information.
When UE enters DRX state of activation, then information is indicated using all or part of DRX activationary time as listening period, Then UE needs a period of time after DRX is active beginning that can obtain new TDD uplink and downlink time scale distribution letter Breath.I.e. as shown in Figure 2 b, the time of UE monitoring PBCH and DRX activationary time are based on there is no on the same start time point This, the present invention implements one and is proposed here by the temporal information comprising at least one MIB sending cycle before DRX activationary time Information is indicated as listening period.Specifically, when configuration UE is in DRX state, DRX activationary time information is determined, it will be true The specified time information in time before fixed DRX activationary time information indicates information, specified time letter as listening period Breath is the sending cycle temporal information of at least one MIB.For example, can indicate that UE M MIB before DRX activationary time sends week The phase corresponding time begins listening for PBCH, wherein M be positive integer, M=1,2,3 ....
As shown in Figure 2 b, using the embodiment of the present invention one propose here by before the DRX activationary time comprising at least The temporal information of one MIB sending cycle as listening period indicate information, can preferably guarantee UE monitor PBCH when Between point and DRX activationary time on the same start time point, in this way, entering before DRX state of activation as UE, just passed through It monitors PBCH and obtains newest TDD uplink and downlink time scale distribution information, when the newest TDD uplink and downlink of acquisition can be used Between pro rate information carry out data transmitting-receiving so that UE can be according to newest TDD or more after entering DRX state of activation Row proportional time carries out data transmission.
Preferably, the third above-mentioned mode can be used in combination with above-mentioned first way or the second way.For example, working as When being used in combination with first way, setting UE M MIB sending cycle corresponding time before DRX activationary time is begun listening for PBCH and then PBCH is monitored with the interval time of at least M MIB sending cycle.Assuming that M=2, each MIB sending cycle are 40ms, DRX activationary time are K, then when being used in combination with first way, in a period of time before DRX activationary time K, A PBCH is monitored according to every 80ms；When being used in combination with the above-mentioned second way, UE M MIB hair before DRX activationary time It send the corresponding time in period to begin listening for PBCH and then PBCH is monitored with M MIB sending cycle during DRX activation, it is assumed that The sending cycle of M=2, each MIB is 40ms, then when being used in combination with the above-mentioned second way, UE is M before DRX activationary time After the MIB sending cycle corresponding time begins listening for PBCH, during DRX activation, PBCH is monitored with the time of 80ms.
4th kind of mode: the time for sending service data information or traffic scheduling solicited message using UE as reference, comes true Determine listening period instruction information.
Service data information can be sent using UE or the time of traffic scheduling solicited message indicates information as listening period； Or the temporal information to carry out traffic scheduling to UE indicates information as listening period.
Preferably, the 4th kind of mode can be used alone, it can also be same with above-mentioned three kinds determining listening period instruction information Shi Zhihang.Using the 4th kind of mode as the constraint condition of aforementioned three kinds of modes, to determine that listening period indicates information.Come as an example It is illustrated: for first way, will indicate that UE monitors the time of PBCH with the sending cycle of the MIB transmitted in PBCH It as reference, determines that listening period indicates that information, this kind of mode and the 4th kind of mode are used in combination, i.e., monitors instruction UE The time of PBCH sends service data information or traffic scheduling request with the sending cycle of the MIB transmitted in PBCH, and with UE The time of information is used as the condition of determination together, to determine that listening period indicates information.Assuming that the sending cycle of MIB is 40ms, press According to first way, information can be indicated using sending cycle, that is, 80ms of two MIB as listening period, and then UE can be sent out Send the time of service data information or traffic scheduling solicited message as constraint, although indicating letter using 80ms as listening period Breath, but UE does not send service data information or traffic scheduling solicited message to network side, then UE will not monitor PBCH.This Sample can further provide that UE monitors the time of PBCH, 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, this In no longer repeat one by one.
Fifth procedure: using the temporal information to UE progress traffic scheduling as reference, to determine listening period instruction letter Breath.
Specifically, information can be indicated as listening period using the temporal information for carrying out traffic scheduling to UE.Preferably, can To indicate information as listening period to send the temporal information that traffic scheduling indicates to UE by down physical channel.Wherein, Down physical channel can be, but not limited to be PDCCH or enhancing down physical channel EPDCCH.
Correspondingly, fifth procedure can singly be not limited to be used alone, can also with it is above-mentioned the first~the third mode Be used in combination, i.e., using fifth procedure as it is above-mentioned the first~constraint condition of the third mode, mode B can be with It is performed simultaneously with above-mentioned three kinds determining listening period instruction information.

Embodiment two
The embodiment of the present invention two proposes a kind of method for monitoring PBCH here, as shown in figure 5, its specific process flow is as follows It states:
Step 51, the listening period instruction information that network side is sent is received.
Network side can be, but not limited to be to receive network side by modes such as RRC information, MAC CE or paging messages The listening period instruction information determined.
Step 52, information is indicated according to the listening period received, monitors PBCH.
Wherein, it in the specific implementation of this step 52, can be, but not limited to include following several ways:
First way: with the sending cycle of the MIB transmitted in PBCH as reference, PBCH is monitored.
Include the sending cycle of the MIB transmitted in PBCH in listening period instruction information.In the side UE, the sending cycle The reception period that UE receives MIB, under this kind of mode, time of each MIB sending cycle that can be transmitted using in PBCH as Listening period, UE monitor PBCH in each MIB reception period, are carried in the reserved bit position of MIB with acquisition New TDD uplink and downlink time scale distributes information.For example, it is assumed that the sending cycle of each MIB is 40ms, then under this kind of mode, UE can indicate information according to the listening period that network side is sent, and every 40ms just monitors a PBCH.I.e. in 0ms, 40ms, 80ms When begin listening for PBCH.
Preferably, monitoring PBCH when UE can transmit the temporal information of at least two MIB in PBCH.
To reduce the frequency that UE monitors PBCH, the electric quantity consumption of UE is reduced, UE can be with the transmission of at least N number of MIB in interval Period monitors PBCH.Wherein N is more than or equal to 2.As N=1, then it represents that each MIB sending cycle of UE requires to monitor PBCH, than Compared with the electricity of waste UE, it is assumed that the sending cycle of N=2, each MIB is 40ms, then when UE can be in 0ms, 80ms, 160ms ... PBCH is begun listening for, distributes information to obtain the new TDD uplink and downlink time scale carried in the reserved bit position of MIB.
SFN in mib information comprising 8 indicates information, can indicate 256 numerical value, 6 among band occupancy PRB is sent.But the time of SFN comes to 1024ms, it is therefore desirable to which 40ms could indicate that once that is, every 40ms sends one A mib information, that is to say, that the sending cycle of MIB is 40ms.In this 40ms, what every 10ms was sent is redundancy versions, i.e. phase It is sent with information using different modulation coding scheme or channel, to guarantee after 40ms integral multiple, is accessed during making UE can obtain the information, while also improve the reliability of data receiver.
Therefore, deviant Offset can be set using N*MIB sending cycle as reference.UE by setting N value and Offset value monitors PBCH.That is UE monitors PBCH in the time of N*MIB sending cycle+Offset*MIB sending cycle.
For example, it is assumed that the sending cycle of each MIB is 40ms, when N=2, Offset=0, UE can 0ms, 80ms, PBCH is begun listening for when 160ms ...；When N=2, Offset=1, begun listening for when UE can be in 40ms, 120ms, 200ms ... PBCH.That is UE can at least monitor a PBCH in the time at interval of at least two MIB.UE is receiving listening period After indicating information, it can be indicated according to listening period in the time of information instruction, at least monitor one in each MIB sending cycle Secondary PBCH.For example, the time of listening period instruction information instruction is that every two MIB sending cycle is begun listening for, i.e., just every 80m Begin listening for PBCH, it is assumed that in 160ms, UE monitor PBCH, further, for guarantee data receiver reliability, 160 During~200ms, UE at least monitors a PBCH, such as UE can monitor a PBCH in 160ms, then in 180ms Monitor a PBCH again, and so on, thus obtain carried in reserved bit position in the mib information transmitted in PBCH it is new TDD uplink and downlink time scale distributes information.
The second way: being reference with DRX activationary time, monitors PBCH according to the listening period instruction information received.
When UE is in DRX state, in all or part of DRX activationary time, PBCH is monitored.
, it is specified that DRX configuration rule for UE, UE only supervise PDCCH during DRX activation in existing standard It listens, is not listening to PDCCH in inactive period UE.But PBCH is monitored for when, existing standard does not make relevant regulations. UE can according to need, and monitor at any time PBCH, i.e., no matter UE is that it is inactive to be in DRX in during DRX activation Period, UE may monitor PBCH.It is being connect in two technique proposed herein scheme of embodiment of the present invention based on this The listening period instruction information received includes DRX activationary time, when UE is in DRX activation, when with all or part of DRX activation Between monitor PBCH, and then obtain TDD uplink and downlink time scale and distribute information.For example, UE can need to supervise in DRX activationary time Listening PBCH, perhaps UE monitors PBCH or UE except DRX during DRX On duration in (part activationary time) PBCH etc. is monitored during OnDuration in outer activationary time.Due to being in DRX inactivation time, biography not in need Defeated data and business, therefore UE does not need to monitor PBCH, can preferably reduce the power consumption of UE.
Preferably, in specific implementation, the above-mentioned second way can be used in combination with first way, i.e., UE is in DRX During activation, using N number of MIB sending cycle as interval, PBCH is monitored.For example, it is assumed that MIB sending cycle is 40ms, N=2, then UE During DRX activation, PBCH is monitored when can be in 80ms, 160ms ....
The third mode: in conjunction with the sending cycle of MIB and the activationary time of DRX, PBCH is monitored.
