Embodiment
For wireless signal by the scene of seriously blocking, the embodiment of the present invention provides a kind of transmission, reception programme of system information, to enable the correct obtaining information of terminal.The core of the scheme that the embodiment of the present invention provides is, network side is within each repetition period of specific SIB: this specific SIB of repetitive schedule, and repeats to send specific SIB at the scheduling occasion of specific SIB; Terminal is within each repetition period of specific SIB: repeat the schedule information receiving this specific SIB, and after acquisition schedule information, repeats to receive downstream signal at the scheduling occasion of specific SIB.
In existing LTE system, at the non-SIB1 of SIB() a repetition period in, this SIB(such as SIB2) only send once.When wireless signal is seriously blocked, terminal needs to merge the downstream signal received in multiple repetition period and obtains system information with demodulation.Obviously, the number of times repeated within a SIB amendment cycle is not enough to the demodulation demand being supported in terminal.The technical scheme that the embodiment of the present invention provides, network side repeats to send specific SIB within a repetition period of specific SIB; Accordingly, terminal can repeat to receive downstream signal by the scheduling occasion of specific SIB within of a specific SIB repetition period, if number of repetition is abundant, then can merges the downstream signal that receives in the repetition period thus correctly demodulate this specific SIB.Even if cannot correctly demodulate this specific SIB within a repetition period, owing to repeating to send specific SIB within the repetition period, so, the number of times repeated within a SIB amendment cycle also at least doubles compared to prior art, thus the demodulation demand of terminal can be met, improve systematic function.
Before the technical scheme that the detailed description embodiment of the present invention provides, first the technical term related in the embodiment of the present invention is made an explanation:
The repetition period of SIB: in existing realization, except SIB1, the repetition period of the SIB of other types refers to the transmission cycle of this SIB.Suppose that the repetition period of SIB2 is 320ms, according to existing realization, every 320ms transmission primaries SIB2.And in the embodiment of the present invention, can repeat to send specific SIB within the repetition period of specific SIB.
The time window (SI-windows) of SI message: except SIB1, the SIB of other types all needs to be mapped in SI message and transmits.Each SI message relating time window, the time window of different SI message is not overlapping, and the length of the time window of each SI message is identical and can be configured by SIB1.SI message is transmitted in dynamic dispatching mode in its time window.So, within the repetition period of specific SIB, the radio frames repeating to transmit specific SIB forms the time window of SI message.
The change of the amendment cycle of SIB: SIB occurs in specific radio frames place.Suppose that network side have sent the Notification of Changes of SIB to terminal, but in this amendment period L, still send/receive current SIB in amendment period L, when next amendment period L+1 arrives by the time, the SIB after sending/receiving changes.
Specific SIB: refer to terminal communicate needed for SIB.For different communication processs or stage of communication, the SIB needed for terminal is different, and so specific SIB is also different.Specifically using the SIB of which kind of type as specific SIB, need according to concrete communication scenes judge, the present invention is not construed as limiting.Such as, in terminal access procedure, need the community radio configuration information carried according to SIB2 to complete access with other base station configuration information, so, SIB2 is exactly specific SIB.
Terminal: the terminal described in the embodiment of the present invention can be MTC terminal certainly, also can be subscriber equipment (UE).But be specially adapted to MTC terminal, especially the MTC terminal of signal serious shielding.
Base station: the base station described in the embodiment of the present invention can be the evolved base station (eNB) in LTE system also can be the base station in the communication system of higher evolution version on LTE system basis.
Below in conjunction with accompanying drawing, the technical scheme that the embodiment of the present invention provides is described in detail.
As shown in Figure 1, in each repetition period of specific SIB, the method that the embodiment of the present invention provides specifically comprises following operation to the sending method of a kind of system information that the embodiment of the present invention provides:
Step 100, repeat the schedule information sending this specific SIB.
Send the schedule information of specific SIB, namely the SI message that this SIB exists mapping relations is dispatched.
Step 110, repeat to send this specific SIB at the scheduling occasion of this specific SIB.
Wherein, within the amendment cycle of this specific SIB, the relative position of subframe in the repetition period that each repetition period sends specific SIB is identical.
In the embodiment of the present invention, the length of the repetition period of specific SIB can be the minimum repetition period notified in SIB1.The length of the repetition period of specific SIB also can be the maximum repetition period notified in SIB1.The length of the repetition period of specific SIB can also be other repetition period length that protocol conventions or network side are determined, is SIB2 for specific SIB, and the length of its repetition period can continue to use current common configuration length 320ms.
It should be pointed out that specific SIB is when transmitting, needing to avoid the subframe that SIB1 and multicast/multicast single-frequency network network (MBSFN) transmit place.If time division duplex (TDD) system, also need to avoid sub-frame of uplink and special subframe.
Based on above-mentioned sending method embodiment, the scheduling occasion of specific SIB, can be made an appointment by agreement or specific SIB that network side is determined repetition period in a continuous N radio frames, also can be that opportunity of the specific SIB of transmission of regulation in the transmission pattern on opportunity (pattern) of this specific SIB of transmission made an appointment by agreement, (namely regulation sent the relative position of radio frames in the repetition period of specific SIB of specific SIB, or, regulation sends numbering in radio frames of the subframe of specific SIB and the relative position of described radio frames in the repetition period of specific SIB).
If in the continuous N of the repetition period of a specific SIB radio frames, repeat to send above-mentioned specific SIB.Namely with this there is the time window of the SI message of mapping relations in specific SIM to this continuous N radio frames.The length (M) of this time window both can be made an appointment in the protocol, also can be determined by network side and inform terminal by SIB1.In addition, can make an appointment in the protocol in the position of this time window in the repetition period, also can be determined by network side and inform terminal by SIB1.
Wherein, both above-mentioned specific SIB can all be sent in each subframe of this continuous N radio frames.Also according to the decision of protocol conventions or network side, the part subframe of this continuous N radio frames can send above-mentioned specific SIB.For the situation sending specific SIB in part subframe, concrete, in this continuous N radio frames, the subframe numbering for sending specific SIB in each radio frames is identical.If determine which subframe is for transmitting specific SIB by network side, then network side also needs, by SIB1, the numbering of these subframes is informed terminal.No matter in all or part of subframe, send specific SIB, the subframe sending specific SIB is not the subframe that SIB1 and MBSFN transmits place, for TDD system, and neither sub-frame of uplink and special subframe.
Wherein, as shown in Figure 2, a kind of implementation of a continuous N radio frames within the repetition period of specific SIB can be: the initial radio frames of this continuous N radio frames, adjacent with last radio frames of dispatching other SIB in the repetition period of specific SIB.
As shown in Figure 3, the another kind of implementation of a continuous N radio frames within the repetition period of specific SIB can be: this continuous N radio frames can be last M the radio frames of the repetition period of specific SIB.
It should be pointed out that in prior art, SIB in a time window of its SI message be mapped to, only transmission primaries.And in the embodiment of the present invention, specific SIB can repeat transmission in the time window of SI message that there are mapping relations with it.
If according to the opportunity of the specific SIB of transmission specified in above-mentioned transmission pattern on opportunity, repeat to send this specific SIB within the repetition period of specific SIB.Concrete, from the transmission pattern on opportunity of (i.e. protocol conventions) the specific SIB of transmission made an appointment, select a transmission pattern(on opportunity as shown in Figure 4); Repeat to send above-mentioned specific SIB according to the transmission pattern on opportunity selected.
Wherein, select the specific implementation of transmission pattern on opportunity to determine according to practical communication demand, such as, the opportunity of the transmission specific SIB of transmission that pattern specify opportunity of selection needs the subframe avoiding transmitting SIB1, the subframe transmitting MBSFN.For TDD system, also need to avoid sub-frame of uplink and special subframe.
Further, within each repetition period of specific SIB, also the selection result of transmission pattern on opportunity is carried in SIB1 and sends to terminal.This selection result both can be the particular content of the transmission pattern on opportunity selected, and also can be mark or the numbering of the transmission pattern on opportunity selected.
Because SI message is by Physical Downlink Control Channel (PDCCH) scheduled transmission.Therefore, for each specific SIB, also transmit corresponding PDCCH to dispatch specific SIB.
Based on above-mentioned any sending method embodiment, preferably, the specific implementation of step 100 can be: in the subframe sending above-mentioned specific SIB, send the PDCCH for dispatching this specific SIB, and the Downlink Control Information that each PDCCH carries (Downlink Control Information, DCI) is identical.That is, the transmission of dispatching the PDCCH of specific SIB is identical with the scheduling occasion of specific SIB for opportunity.Certainly, dispatch the transmission opportunity of the PDCCH of specific SIB, also can early than the scheduling occasion of specific SIB.
As shown in Figure 5, in each repetition period of specific SIB, the method that the embodiment of the present invention provides specifically comprises following operation to the method for reseptance of a kind of system information that the embodiment of the present invention provides:
Step 500, repeat the schedule information receiving this specific SIB.
To the length of the repetition period of specific SIB, identical with the length that network side sends the repetition period of specific SIB, specifically with reference to the description of above-mentioned sending method side embodiment, can repeat no more here.
Step 510, obtain this specific SIB schedule information after, repeat to receive downstream signal at the scheduling occasion of this specific SIB, to obtain this specific SIB according to the downstream signal received.
Wherein, within the amendment cycle of specific SIB, the relative position of subframe in the repetition period that each repetition period receives above-mentioned downstream signal is identical.
Based on above-mentioned method of reseptance embodiment, the scheduling occasion of specific SIB, can be made an appointment by agreement or a continuous N radio frames in repetition period that network side is determined, also can be that opportunity of the specific SIB of transmission of regulation in the transmission pattern on opportunity (pattern) of this specific SIB of transmission made an appointment by agreement, (namely regulation sent the relative position of radio frames in the repetition period of specific SIB of specific SIB, or regulation sends numbering in radio frames of the subframe of specific SIB and the relative position of described radio frames in the repetition period of specific SIB).
If in the continuous N of the repetition period of a specific SIB radio frames, repeat to receive downstream signal.This continuous N radio frames is the time window that specific SIM with this exists the SI message of mapping relations.The length (M) of this time window both can be made an appointment in the protocol, also can know from SIB1.In addition, can make an appointment in the protocol in the position of this time window in the SI cycle, also can know from SIB1.
Wherein, if network side all sends above-mentioned specific SIB in each subframe of this continuous N radio frames.Then terminal all can receive downstream signal in each subframe of this continuous N radio frames.Certainly, if receive downstream signal by several subframes before merging correctly demodulate specific SIB, then in this M radio frames subsequent subframe, downstream signal corresponding to specific SIB is received without the need to continuing.
If network side sends above-mentioned specific SIB in the part subframe of a continuous N radio frames.Then terminal can receive downstream signal in the part subframe of this continuous N radio frames.Certainly, if receive downstream signal by some subframes before merging correctly demodulate specific SIB, then in this M radio frames subsequent subframe, downstream signal corresponding to specific SIB is received without the need to continuing.
For the situation receiving downstream signal in part subframe, concrete, in this continuous N radio frames, the subframe numbering for sending specific SIB in each radio frames is identical.If determine which subframe is for transmitting specific SIB, then terminal knows the numbering of these subframes in SIB1 by network side.
No matter in all or part of subframe, receive downstream signal, the subframe receiving downstream signal is not the subframe that SIB1 and MBSFN transmits place, for TDD system, and neither sub-frame of uplink and special subframe.
In all or part of subframe of a continuous N radio frames of the repetition period of specific SIB, receive described downstream signal, the subframe receiving described downstream signal is not the subframe that SIB1 and multicast/multicast single-frequency network network MBSFN transmit place, neither sub-frame of uplink and special subframe.
Wherein, the specific implementation of a continuous N radio frames within the SI cycle is identical with the network side sending specific SIB.Specifically see the description of above-mentioned sending method embodiment, can repeat no more here.
If according to the opportunity of the specific SIB of transmission specified in above-mentioned transmission pattern on opportunity, repeat to receive downstream signal within the repetition period of specific SIB.So, within each repetition period of specific SIB, from the SIB1 received, also obtain the selection result of the transmission pattern on opportunity sending this specific SIB; From the transmission pattern on opportunity of the specific SIB of the transmission of making an appointment, determine the transmission pattern on opportunity that selection result indicates; Repeat to receive downstream signal according to the transmission pattern on opportunity determined.Wherein, the description for the transmission pattern on opportunity sending this specific SIB with reference to above-mentioned sending method embodiment, can repeat no more here.
Because SI message is by PDCCH scheduled transmission.Therefore, for each specific SIB, the schedule information of specific SIB is also obtained from corresponding PDCCH.Based on above-mentioned any method of reseptance embodiment, preferably, the specific implementation of step 500 can be: in the subframe receiving above-mentioned downstream signal, receive the PDCCH for dispatching specific SIB, and the DCI that each PDCCH carries is identical.That is, the transmission of dispatching the PDCCH of specific SIB is identical with the scheduling occasion of specific SIB for opportunity.Certainly, dispatch the transmission opportunity of the PDCCH of specific SIB, also can early than the scheduling occasion of specific SIB.
For the scheduling occasion shown in Fig. 2, specific SIB is sent to network side, and the specific implementation that terminal receives specific SIB is described.
Wherein, the processing procedure of network side can be described as:

Concrete, terminal is in this M radio frames, and SIB1 transmits in each subframe outside the subframe at place and the subframe at MBSFN transmission place, and the PDCCH of the specific SIB of receiving scheduling, the DCI of the PDCCH that these subframes are transmitted is identical.After the signal received by merging correctly demodulates PDCCH, therefrom obtain the schedule information of specific SIB.Certainly, if just correctly demodulate PDCCH by the signal that assembling section subframe receives, then follow-up need not continuation receives PDCCH.
After the schedule information obtaining specific SIB, terminal, in these subframes, the running time-frequency resource that the schedule information of specific SIB indicates receives downstream signal.Specific SIB is correctly demodulated by merging the downstream signal received.Certainly, if just correctly demodulate specific SIB by the signal that assembling section subframe receives, then follow-up need not continuation continues to receive downstream signal on the running time-frequency resource of schedule information instruction.
If PDCCH is first by correct demodulation, is that terminal only needs to receive downstream signal corresponding to specific SIB in certain subframe by situation about there will be, do not need to receive PDCCH.So, terminal according to the schedule information of the specific SIB carried in the PDCCH correctly demodulated before, the running time-frequency resource that this schedule information indicates can receive downstream signal.
