The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one,
The embodiments of the invention provide a kind of system message transmission method, methods described includes:Found in cell with reference to letter Number (DRS, Discover Reference Signal) sends critical system message and replenishment system message in transmission opportunity In at least one system message.
Specifically, the system message transmission method that the present embodiment provides, as shown in figure 1, including:
Step 101:At least one system message is at least divided at least one critical system message and at least one Replenishment system message;
Step 102:At least one critical system message and/or a replenishment system message bearing are sent into opportunity in DRS Physical Downlink Shared Channel PDSCH and/or enhanced Physical Downlink Shared Channel ePDSCH in and send.
The present embodiment can apply in the base station in GSM, especially can apply to evolution base station (eNB).It is pointed out that application scenarios new described in the present embodiment, are not limited to LTE technologies being applied to unlicensed spectrum On.The present embodiment can also be applied in other various communication systems, such as 5G technologies are applied in unlicensed spectrum.More enter One step, in some new LTE or 5G application scenarios, in super-intensive networking scene or flexible downstream transmission scene, this Embodiment is also possible to be applied to and authorized on frequency spectrum.
The present embodiment illustrates first against the time-domain transmission of system message, specific as follows:
Above-mentioned transmission critical system message and replenishment system message can be in cell find reference signal transmission opportunity It is transmitted.
For LTE technologies, at least one system message, which comprises at least, Master Information Block MIB and at least two systems Message blocks of uniting SIB;Wherein, at least two SIB can be for one or more of SIB1~SIB13, the number specifically included Measure in the present embodiment without limiting.
Part SIB in MIB and at least two SIB at least one system message is divided into critical system Message;At least one SIB that removing is divided to outside the basic part SIB of the first kind at least two SIB is divided into benefit Charging system message.
Specifically, critical system message is in LTE system, can be by systems such as MIB message, SIB1 message, SIB2 message Message is regarded as critical system message;And other SIB message are regarded as replenishment system message.
For 5G technologies, system message species might have other new definition, and critical system message and replenishment system The attaching relation of message may do new division, no longer be carried out in the present embodiment exhaustive.
Further, methods described also includes:By find reference signal send opportunity configure DMTC windows in can With sub-frame transmission system message.Wherein, the DMTC windows are specially to find that reference signal sends opportunity configuration (DRS Measurement Timing Configuration) window.In addition, described may in different application scenarios with subframe Difference, such as, it is described can be determined with subframe according to the LBT of base station side result in unlicensed spectrum application scenarios, Specifically, if base station side LBT result shows that the subframe position can be used for transmitting data, then the subframe can be thought Subframe can be used;In 5G application scenarios, eNB may be by default rule, for example some technical criterias are selected in DMTC windows The system message can be transmitted with subframe by selecting, and its corresponding technical criteria not carried out in the present embodiment exhaustive.
Such as referring to Fig. 2, it may be determined that determine 6ms as DMTC windows in the wireless sub-frame in transmission subframe per 10ms. It is noted that eNB in each DMTC windows, at most only can transmit 1 DRS occasion.
ENB is firstly the need of configuration DMTC windows.The DMTC windows configuration of standardization acquiescence (provides acquiescence in a standard DMTC sends cycle and sub-frame offset).ENB selects a subset in DMTC window set is given tacit consent to, and builds itself actual use DMTC windows.ENB attempts to send DRS signals in the DMTC windows actually used;
If the DMTC window periods of acquiescence are T1, sub-frame offset Offset1;
Then the cycle of the actual DMTC windows used of eNB is N1 × T1, offsets as Offset1+k*T1, wherein, k=0, 1,…,N1-1;
ENB is notified the DMTC windows actually used configuration (i.e. transmission cycle and transmission deviation) by the first system message To the UE serviced, specific notification field can be N1, k;
And/or
ENB is by RRC signaling, and by the actual DMTC windows configuration used in neighbor cell, (i.e. transmission cycle and transmission is inclined Move) notify to the UE serviced.If define the DMTC window periods and sub-frame offset of acquiescence, then specific notification field can To be N1, k.Otherwise, specific notification field can be the transmission cycle and transmission deviation represented with subframe.
Wherein, according to preset rules, in the available subframe in all or part of DMTC windows the first system is transmitted to disappear Breath.
Need further exist for illustrating, in the present embodiment in DMTC window set, system message uses paging in time domain (paging) mode carries, that is, the system message having is configured to transmit in each DMTC windows, and some system message quilts It is configured to only transmit in the DMTC windows of part.It is noted that system message is configured to transmit in specific DMTC windows, no Transmission opportunity can necessarily be obtained by representing the system message.
For each system message delimiting period and skew (offset), wherein the cycle of system message and skew be Defined on the basis of the DMTC cycles.
Can have on time domain set-up mode in the present embodiment following several:
The first, at least one system message configure transmission cycle and transmission deviation;Wherein, the transmission cycle and Transmission deviation is to find that reference signal sends the integral multiple of opportunity configuration DMTC windows.
The information transmitted in present treatment mode in each DRS transmission opportunity may refer to Fig. 3, pass through table 1 with reference to Fig. 3 Illustrate transmission cycle and the transmission deviation configuration of each system message:
Table 1
Above-mentioned base station side processing basis on, further illustrate UE obtain said system message when configuration of territory side Formula can include:By standard agreement, the transmission cycle and transmission deviation of some prespecified critical system message.For example, In the present embodiment, by standard agreement, prespecified system message 1 and second system message are transmitted in each DMTC windows. Therefore, UE attempts system message 1 and second system message corresponding to reception and demodulation in each DMTC windows.
Especially, in figure 3, the system message by the prespecified transmission cycle of standard agreement and transmission deviation is referred to as First kind critical system message.In second system message, the time domain configuration information of other parts replenishment system information, bag are carried Include transmission cycle and transmission deviation.
After UE is properly received and demodulates second system message, with regard to can obtain other remaining system message transmission cycle and Transmission deviation.Then, UE calculates the DMTC windows corresponding to it according to these system message transmission cycles and transmission deviation Mouthful, then in these DMTC windows, attempt system message corresponding to reception and demodulation.Especially, in figure 3, will be passed through Two system message provides that the critical system message of transmission cycle and transmission deviation is referred to as the second class critical system message.
Especially, second system message is identical or different from the first system message.So-called the first system message and second System message is identical, refers to disappearing in the first system message while including at least one other systems message and/or system The transmission cycle and transmission deviation of breath group, and DMTC window configuration parameters.
The information included in the second system message may refer to shown in table 2:
The quantity in DMTC cycles Transmission deviation Remarks
System message 2 1 0 Repeated in each DMTC
System message 3 2 0 Cycle=2TDMTC
System message 4 2 1 Cycle=2TDMTC
System message 5 4 0 Cycle=4TDMTC
System message 6 4 1 Cycle=4TDMTC
System message 7 4 2 Cycle=4TDMTC
System message 8 4 3 Cycle=4TDMTC

The mapping relations of system message group and system message SI windows are established, wherein, the system message group includes at least One system message;Transmission cycle and transmission deviation are configured at least one SI windows;Wherein, the transmission cycle and transmission Skew is the integral multiple of DMTC windows.
The concept of system message (SI, System Information) window in LTE system is used for reference, defines the week of SI windows Phase and offset, and the mapping relations of SI windows and system message are defined, the wherein cycle of SI windows and skew is in DMTC Defined on the basis of cycle.
With the first time domain set-up mode, pass through standard agreement, the transmission of some prespecified critical system message first Cycle and transmission deviation.For example, in the present embodiment, by standard agreement, prespecified system message 1 and second system message Transmitted in each DMTC windows.Therefore, UE attempts system message 1 and second corresponding to reception and demodulation in each DMTC windows System message.Especially, in Fig. 4, the system message by the prespecified transmission cycle of standard agreement and transmission deviation is claimed Make first kind critical system message.
Control second system message is based on default transmission cycle and transmission deviation, and at least one replenishment system is notified to UE The transmission cycle and transmission deviation of message and/or SI windows;Specifically, in second system message, other parts system is carried The configuration information of SI windows corresponding to information group, including the transmission cycle of each SI windows, transmission deviation and SI windows with extremely The mapping relations of a few system message.After UE is properly received and demodulates second system message, with regard to other residue systems can be obtained The transmission cycle and transmission deviation of SI windows corresponding to message groups of uniting.Then, UE is according to the transmission cycles of these SI windows And transmission deviation, the DMTC windows corresponding to it are calculated, then in these DMTC windows, are attempted corresponding to reception and demodulation System message.Especially, in Fig. 4, it will provide that the critical system of transmission cycle and transmission deviation disappears by second system message Breath is referred to as the second class critical system message.
The information included in the second system message may refer to shown in table 3:
Table 3
Further, by the transmission cycle and transmission deviation of the configuration, it is determined that for send the system message or First DMTC windows of system message group;By system message described in the available sub-frame transmission in the first DMTC windows or it is System message groups.
It is described in DRS transmission opportunitys, send at least one in the critical system message and replenishment system message System message, including:
At least one in the critical system message and replenishment system message is carried on the DRS and sends opportunity In Physical Downlink Shared Channel PDSCH and/or enhanced Physical Downlink Shared Channel ePDSCH and send.
It can be seen that by using such scheme, it becomes possible to chosen from system message and obtain at least one critical system message And replenishment system message, and for choosing different transmission cycles and progress in DRS opportunitys per a kind of system message Transmission.In this way, ensure the transmission density of system message so that the reliability of the transmission of system message is guaranteed.
