Accordingly, second network side apparatus 20 is received after the first sequence number 2, according to table 3, has just been known the type of each subframe.
The corresponding relation of type configuration form and the first sequence number can be stipulated in advance in agreement, also can be notified by high level.Can also upgrade the corresponding relation of configuration format and sequence number as required.
Owing to being not dynamic assignment, uplink-downlink configuration information that network interface is mutual.Therefore,, if notify in force certain subframe for fixing subframe, its transmission direction implication indicated with the uplink-downlink configuration information of having notified is identical; If notifying certain subframe is variable subframe, the indicated implication of its transmission direction and the uplink-downlink configuration information of having notified has nothing to do.
Preferably, first network side apparatus 10 can also be placed in announcement information by transmission direction information.Transmission direction information represents that each subframe is uplink or downlink transfer.
Concrete, first network side apparatus 10 can, according to the subframe in the radio frames of this cell configuration, be determined transmission direction information.
It is a variety of that first network side apparatus 10 determines that the mode of transmission direction information has, and enumerates several below.

Suppose that time span is 10ms (i.e. a radio frames length).The transmission direction of subframe 2, subframe 7, subframe 8 and subframe 9 is up." 1 " represents that transmission direction is up, and " 0 " represents that transmission direction is descending, as shown in table 4:
Table 4
Concrete transmission direction bitmap is 0010000111.
Accordingly, after second network side apparatus 20 receives 0010000111, according to the implication of subframe that in transmission direction bitmap, each bit is corresponding and numerical value corresponding to each bit, just known the transmission direction of each subframe.
Concrete duration can be stipulated in agreement, also can be notified by high level.Can also upgrade the duration of setting as required.
Concrete transmission direction bitmap represents that subframe which subframe, each bit are corresponding and the implication of each bit numerical value can stipulate in agreement, can also be notified by high level.
Mode two, first network side apparatus 10 are according to the corresponding relation of transmission direction configuration format and the second sequence number, determine fixedly subframe in certain hour length and second sequence number corresponding to transmission direction configuration format of variable subframe, and using the second sequence number of determining as transmission direction information.
The corresponding relation of transmission direction configuration format and the second sequence number can be referring to table 5.
(D represents descending table 5; U represents up)
Suppose that time span is 10ms (i.e. a radio frames length), the transmission direction of subframe 2, subframe 3, subframe 4 and subframe 7 is up; The transmission direction of subframe 0, subframe 1, subframe 5, subframe 6, subframe 8 and subframe 9 is descending.According to table 5, just can determine that the first sequence number is 3.
Accordingly, second network side apparatus 20 is received after the first sequence number 3, according to table 5, has just been known the type of each subframe.
The corresponding relation of type configuration form and the first sequence number can be stipulated in advance in agreement, also can be notified by high level.Can also upgrade the corresponding relation of configuration format and sequence number as required.
Wherein, first network side apparatus 10 can send transmission direction information and type information by two different announcement informations; Also transmission direction information and type information all can be placed in to same announcement information.
If first network side apparatus 10 is all placed in same announcement information by transmission direction information and type information, first network side apparatus 10 is combined into configuration information by transmission direction information and type information, and configuration information is placed in to announcement information.
Concrete configuration information can be type bitmap+ transmission direction bitmap; Type bitmap+ the second sequence number; The first sequence number+transmission direction bitmap; A kind of in the first sequence number+the second sequence number.
That can the regulation in agreement of concrete employing; Can also be notified by high level.
If configuration information can be type bitmap+ transmission direction bitmap, can first half be type bitmap, latter half is transmission direction bitmap; Also can first half be transmission direction bitmap, latter half be type bitmap; Type bitmap and transmission direction bitmap can also be mixed.
If type bitmap and transmission direction bitmap are mixed, can directly the type information of each subframe and transmission direction information be notified to adjacent cell by more than one bit information.
Suppose that time span is 10ms (i.e. a radio frames length), subframe 0, subframe 1, subframe 2, subframe 5, subframe 6 and subframe 7 are fixing subframes, subframe 3, subframe 4, subframe 8 and subframe 9 are that variable subframe " 1 " represents fixedly subframe, and " 0 " represents variable subframe; Subframe 2, subframe 7, subframe 8 and subframe 9 transmission directions are up, and subframe 0, subframe 1, subframe 3, subframe 4, subframe 5 and subframe 6 transmission directions are descending, 1 " represent that transmission direction is up, and " 0 " represents that transmission direction is descending, as shown in table 6:
Table 6
Concrete configuration information is 00000110100000011111.
Accordingly, after second network side apparatus 10 receives 00000110100000011111, according to just having known the type of each subframe and transmission direction according to the implication of subframe that in type bitmap and transmission direction bitmap, each bit is corresponding and numerical value corresponding to each bit respectively.
Wherein, network equipment can also be placed in announcement information by one or more in following message as required:
The cell ID of the cell ID of this community, the PLMN of this community (Public Land Mobile Network, Public Land Mobile Nerwork) sign and adjacent cell.
In force, first network side apparatus 10 can send to adjacent cell by notification message by direct communication interface or indirect communication interface.
For example having (as Macro (grand) community, Pico community etc.) between the community that X2 connects can use X2 interface to send; Do not have between community that X2 interface connects (as femto community etc.) can use S1 interface.
Second network side apparatus 20, according to the announcement information of the containing type information of receiving, is determined the type of each subframe in this community radio frames, and then the subframe in the radio frames of Dui Zhe community is configured.
Wherein, the interference strength between the adjacent cell that second network side apparatus 20 judges whether can detect this community and send announcement information.
The interference strength here includes but not limited to a kind of in lower train value:
RSRP (Reference signal received power, Reference Signal Received Power) value, RIP (Received Interference Power, interference received power) value, CQI (Channel QualityIndicator, channel quality indication) value and RSRQ (Reference Signal Received Quality, Reference Signal Received Quality) value.
Determine can not detect this community with send between the adjacent cell of announcement information interference strength time, if need the subframe configuring, in adjacent cell, be variable subframe, second network side apparatus 20 is not used this subframe or reduces the use priority of this subframe.
Concrete, second network side apparatus 20 can be mixed with obsolete subframe MBSFN (MBSFNMulticast Broadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) subframe or ABS (Almost Blank Subframe, blank subframe) or sub-frame of uplink but do not carry out uplink scheduling.
If announcement information comprises transmission direction information, and determine the interference strength between the adjacent cell that can not detect this community and send announcement information, if need the subframe of configuration when adjacent cell is variable subframe, the subframe type that second network side apparatus 20 can configure is identical with subframe type and the transmission direction of same subframe sign in adjacent cell with transmission direction.
Such as subframe 7 and subframe 8 are variable subframes, subframe 7 that can Jiang Zhe community is configured to the transmission direction identical with the subframe 7 of adjacent cell; The subframe 8 of Jiang Zhe community is configured to the transmission direction identical with the subframe 8 of adjacent cell.
In the interference strength of determining between the adjacent cell that can not detect this community and send announcement information, if the subframe that needs configuration is fixing subframe in adjacent cell, the subframe type that second network side apparatus 20 can configure is identical with subframe type and transmission direction that in adjacent cell, same subframe identifies with transmission direction.
Because fixedly the transmission direction of subframe can be definite according to predefined information or uplink-downlink configuration information, so if do not comprise transmission direction information in announcement information, also can know the fixedly transmission direction of subframe.Certainly, if announcement information comprises transmission direction information, with the transmission direction information in announcement information, be as the criterion.
Wherein, if second network side apparatus 20 is determined the interference strength between the adjacent cell that can detect this community and send announcement information, further interference strength and threshold value are compared.The setting of concrete threshold value can be based on experience value or simulation result in agreement, stipulate or notified by high level.Different threshold value corresponding to interference strength.
If interference strength is not less than threshold value, and need the subframe of configuration when adjacent cell is variable subframe, second network side apparatus 20 is not used this subframe or reduces the use priority of this subframe.Do not use the concrete mode of subframe identical with the above-mentioned mode of subframe of not using, do not repeat them here.
If interference strength is not less than threshold value, no matter be variable subframe or fixing subframe, second network side apparatus 20 can be configured according to the subframe in the radio frames of default configuration information Dui Zhe community, or the subframe in the unified configuration information Dui Zhe community radio frames issuing according to network side is configured, or while also comprising transmission direction information in announcement information, according to the subframe in the announcement information Dui Zhe community radio frames of receiving, be configured.
If interference strength is less than threshold value, no matter be variable subframe or fixing subframe, the subframe in second network side apparatus 20 autonomous Dui Zhe community radio frames is configured.
When autonomous configuration, second network side apparatus 20 can be considered a kind of in the situations such as business demand, channel load, terminal quantity, also can consider multiplely, and then the subframe in the radio frames of Dui Zhe community is configured as the case may be.
Such as ascending load is overweight, can many collocating uplinks subframe; Downlink business is too much, can many configurating downlinks subframe etc.

As shown in Figure 5, the method for embodiment of the present invention transmission information comprises the following steps:
Step 501, network equipment are according to the subframe in the radio frames of this cell configuration, determine type information, wherein radio frames comprises variable subframe and/or fixing subframe, and variable subframe is the variable subframe of transmission direction, and fixedly subframe is the changeless subframe of transmission direction.
Step 502, network equipment send to adjacent cell by the announcement information that contains type information.
Wherein, the adjacent cell is here co-frequency neighbor cell or iso-frequency adjacent community; And this community and adjacent cell can be in same TDD network adjacent cell or different TDD network.
In step 501, it is a variety of that network equipment determines that the mode of type information has, and enumerates several below.
Mode one, network equipment arrange in certain hour length the fixedly numerical value of subframe corresponding bit in type bitmap (bit map), and the numerical value of variable subframe corresponding bit in type bitmap in setup times length, and using type bitmap as type information.
In force, type bitmap can only represent in certain hour length the fixedly type information of subframe.
Suppose that time span is 10ms (i.e. a radio frames length), subframe 0, subframe 1, subframe 2, subframe 5, subframe 6 and subframe 7 are fixing subframes." 1 " represents fixedly subframe, and " 0 " represents variable subframe, as shown in table 1, and concrete type bitmap is 1110011100.
In force, type bitmap can only represent the type information of variable subframe in certain hour length.
Suppose that time span is 10ms (i.e. a radio frames length), subframe 3, subframe 4, subframe 8 and subframe 9 are variable subframes." 1 " represents fixedly subframe, and " 0 " represents variable subframe, as shown in table 2, and concrete type bitmap is 0001100011.
Concrete duration can be stipulated in agreement, also can be notified by high level.Can also upgrade the duration of setting as required.
Particular type bitmap represents that subframe which subframe, each bit are corresponding and the implication of each bit numerical value can stipulate in agreement, can also be notified by high level.
Mode two, network equipment be according to the corresponding relation of type configuration form and the first sequence number, determines fixedly subframe in certain hour length and first sequence number corresponding to type configuration form of variable subframe, and using the first sequence number of determining as type information.
The corresponding relation of type configuration form and the first sequence number can be referring to table 3.
The corresponding relation of type configuration form and the first sequence number can be stipulated in advance in agreement, also can be notified by high level.Can also upgrade the corresponding relation of configuration format and sequence number as required.
Owing to being not dynamic assignment, uplink-downlink configuration information that network interface is mutual.Therefore,, if notify in force certain subframe for fixing subframe, its transmission direction implication indicated with the uplink-downlink configuration information of having notified is identical; If notifying certain subframe is variable subframe, the indicated implication of its transmission direction and the uplink-downlink configuration information of having notified has nothing to do.
Preferably, network equipment can also be placed in announcement information by transmission direction information.Transmission direction information represents that each subframe is uplink or downlink transfer
Concrete, in step 501, network equipment can also, according to the subframe in the radio frames of this cell configuration, be determined transmission direction information.
It is a variety of that network equipment determines that the mode of transmission direction information has, and enumerates several below.
Mode one, network equipment arrange in certain hour length the fixedly numerical value of subframe corresponding bit in transmission direction bitmap, and the numerical value of variable subframe corresponding bit in transmission direction bitmap in setup times length, and using transmission direction bitmap as transmission direction information.
Suppose that time span is 10ms (i.e. a radio frames length).The transmission direction of subframe 2, subframe 7, subframe 8 and subframe 9 is up." 1 " represents that transmission direction is up, and " 0 " represents that transmission direction is descending, and as shown in table 4, concrete transmission direction bitmap is 0010000111.
Concrete duration can be stipulated in agreement, also can be notified by high level.Can also upgrade the duration of setting as required.
Concrete transmission direction bitmap represents that subframe which subframe, each bit are corresponding and the implication of each bit numerical value can stipulate in agreement, can also be notified by high level.
Mode two, network equipment are according to the corresponding relation of transmission direction configuration format and the second sequence number, determine fixedly subframe in certain hour length and second sequence number corresponding to transmission direction configuration format of variable subframe, and using the second sequence number of determining as transmission direction information.
The corresponding relation of transmission direction configuration format and the second sequence number can be referring to table 5.
Suppose that time span is 10ms (i.e. a radio frames length), the transmission direction of subframe 2, subframe 3, subframe 4 and subframe 7 is up; The transmission direction of subframe 0, subframe 1, subframe 5, subframe 6, subframe 8 and subframe 9 is descending.According to table 5, just can determine that the first sequence number is 3.
The corresponding relation of type configuration form and the first sequence number can be stipulated in advance in agreement, also can be notified by high level.Can also upgrade the corresponding relation of configuration format and sequence number as required.
In step 502, network equipment can send transmission direction information and type information by two different announcement informations; Also transmission direction information and type information all can be placed in to same announcement information.
If network equipment is all placed in same announcement information by transmission direction information and type information, network equipment is combined into configuration information by transmission direction information and type information, and configuration information is placed in to announcement information.
Concrete configuration information can be type bitmap+ transmission direction bitmap; Type bitmap+ the second sequence number; The first sequence number+transmission direction bitmap; A kind of in the first sequence number+the second sequence number.
That can the regulation in agreement of concrete employing; Can also be notified by high level.
If configuration information can be type bitmap+ transmission direction bitmap, can first half be type bitmap, latter half is transmission direction bitmap; Also can first half be transmission direction bitmap, latter half be type bitmap; Type bitmap and transmission direction bitmap can also be mixed.
If type bitmap and transmission direction bitmap are mixed, can directly the type information of each subframe and transmission direction information be notified to adjacent cell by more than one bit information.
Suppose that time span is 10ms (i.e. a radio frames length), subframe 0, subframe 1, subframe 2, subframe 5, subframe 6 and subframe 7 are fixing subframes, subframe 3, subframe 4, subframe 8 and subframe 9 are that variable subframe " 1 " represents fixedly subframe, and " 0 " represents variable subframe; Subframe 2, subframe 7, subframe 8 and subframe 9 transmission directions are up, and subframe 0, subframe 1, subframe 3, subframe 4, subframe 5 and subframe 6 transmission directions are descending, 1 " represent that transmission direction is up, and " 0 " represents that transmission direction is descending, as shown in table 6.Concrete configuration information is 00000110100000011111.
Wherein, network equipment can also be placed in announcement information by one or more in following message as required:
