Wherein, the send mode of transmission information has a lot.Such as by network interface (OAM (Operations﹠amp for example; Maintenance, operation and safeguard) interface) read transmission information; Directly read the high-level signaling that carries transmission information and obtain transmission information.
Need to prove that the embodiment of the invention is not limited to above-mentioned several mode, other modes that can send transmission information all are suitable for the embodiment of the invention.
Preferable, second network equipment 20 can also carry out down-going synchronous with first network equipment 10 before receiving the control signaling, reads the system broadcast information of adjacent sub-district then, thereby knows the information of adjacent sub-district.
If first network equipment 10 just can controlled signaling when then second network equipment 20 reads the system broadcast information of adjacent sub-district by the system broadcast information control channel.Otherwise, read after the system broadcast information of adjacent sub-district, receive the control signaling.
Wherein, the radio frames of the embodiment of the invention comprises that variable subframe and/or the changeless fixedly subframe of transmission direction that transmission direction is variable represent three kinds of situations.1, the subframe in the radio frames is variable subframe entirely; 2, the subframe in the radio frames is fixing subframe entirely; 3, the subframe in the radio frames has variable subframe and fixing subframe.
Variable subframe is that can carry out as required can dynamic-configuration.It is descending to be such as current period that the up next cycle just might become, and fixedly subframe is the subframe that transmission direction can not change.
It is a variety of that first network equipment 10 determines that the mode of type information has, and enumerates several below.
Mode one, first network equipment 10 are provided with in the certain hour length fixedly first sign of subframe corresponding bit position in type bitmap (bit map), and second sign that the corresponding bit position in type bitmap of variable subframe in the time span is set, and with type bitmap as type information.
In force, type bitmap can only represent in the certain hour length the fixedly type information of subframe.
Suppose that time span is 10ms (i.e. radio frames length), subframe 0, subframe 1, subframe 2, subframe 5, subframe 6 and subframe 7 are fixing subframes.First sign is represented fixedly subframe with " 1 ", and second sign is represented variable subframe with " 0 ", and is then as shown in table 1:
Figure BDA0000052653830000081
Table 1
Concrete type bitmap is 1110011100.Be that type information is 1110011100.
Accordingly, after second network equipment 20 receives 1110011100, just known the type of each subframe according to the subframe of each bit correspondence among the type bitmap and the implication of each bit corresponding identification.
In force, type bitmap can only represent the type information of variable subframe in the certain hour length.
Suppose that time span is 10ms (i.e. radio frames length), subframe 3, subframe 4, subframe 8 and subframe 9 are variable subframes." 1 " expression is subframe fixedly, and " 0 " represents variable subframe, and is then as shown in table 2:
Figure BDA0000052653830000082
Table 2
Concrete type bitmap is 0001100011.
Accordingly, after second network equipment 20 receives 0001100011, just known the type of each subframe according to the subframe of each bit correspondence among the type bitmap and the implication of each bit corresponding identification.
Concrete duration can be stipulated in agreement, also can be notified by high level.Can also the duration of setting be upgraded as required.
Particular type bitmap represents that the implication of the subframe of which subframe, each bit correspondence and each bit sign can stipulate in agreement, can also be notified by high level.
Mode two, first network equipment 10 are according to the corresponding relation of the type configuration pattern and first sequence number, determine first sequence number of the type configuration pattern correspondence of fixedly subframe in the certain hour length and variable subframe, and first sequence number that will determine is as type information.
The corresponding relation of the type configuration pattern and first sequence number can be referring to table 3.
Table 3
Suppose that time span is 10ms (i.e. radio frames length), subframe 3, subframe 4, subframe 8 and subframe 9 are variable subframes; Subframe 0, subframe 1, subframe 2, subframe 5, subframe 6 and subframe 7 are fixing subframes.Just can determine that according to table 3 first sequence number is 1.
Accordingly, second network equipment 20 has just been known the type of each subframe according to table 3 after receiving first sequence number 2.
The corresponding relation of the type configuration pattern and first sequence number can be stipulated in agreement in advance, also can be notified by high level.Can also the corresponding relation of configuration format and sequence number be upgraded as required.
Since when being not dynamic assignment, uplink-downlink configuration information that network interface is mutual.Therefore, if notify certain subframe to be fixing subframe in force, the indicated implication of its transmission direction and 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.
Preferable, first network equipment 10 can also place transmission direction information the control signaling.Each subframe of transmission direction information representation is uplink or downlink transfer.
Concrete, first network equipment 10 can be determined transmission direction information according to the subframe in the radio frames of this cell configuration.
It is a variety of that first network equipment 10 determines that the mode of transmission direction information has, and enumerates several below.
Mode one, first network equipment 10 are provided with in the certain hour length fixedly the 3rd sign of subframe corresponding bit position in transmission direction bitmap, and the 4th sign that variable subframe corresponding bit position in transmission direction bitmap in the time span is set, and with transmission direction bitmap as transmission direction information.
Suppose that time span is 10ms (i.e. radio frames length).The transmission direction of subframe 2, subframe 7, subframe 8 and subframe 9 is up." 1 " expression transmission direction is up, and " 0 " expression transmission direction is descending, and is then as shown in table 4:
Figure BDA0000052653830000101
Table 4
Concrete transmission direction bitmap is 0010000111.
Accordingly, after second network equipment 20 receives 0010000111, just known the transmission direction of each subframe according to the subframe of each bit correspondence among the transmission direction bitmap and the implication of each bit corresponding identification.
Concrete duration can be stipulated in agreement, also can be notified by high level.Can also the duration of setting be upgraded as required.
Concrete transmission direction bitmap represents that the subframe of which subframe, each bit correspondence and the implication of each bit sign can stipulate in agreement, can also be notified by high level.
Mode two, first network equipment 10 are according to the corresponding relation of the transmission direction configuration format and second sequence number, determine second sequence number of the transmission direction configuration format correspondence of fixedly subframe in the certain hour length and variable subframe, and second sequence number that will determine is as transmission direction information.
The corresponding relation of the transmission direction configuration format and second sequence number can be referring to table 5.
Figure BDA0000052653830000111
(D represents descending table 5; U represents up)
Suppose that time span is 10ms (i.e. 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.Just can determine that according to table 5 first sequence number is 3.
Accordingly, second network equipment 20 has just been known the type of each subframe according to table 5 after receiving first sequence number 3.
The corresponding relation of the type configuration pattern and first sequence number can be stipulated in agreement in advance, also can be notified by high level.Can also the corresponding relation of configuration format and sequence number be upgraded as required.
Wherein, first network equipment 10 can send with type information transmission direction information by two different control signalings; Also transmission direction information and type information all can be placed same control signaling.
If first network equipment 10 all places same control signaling with transmission direction information and type information, then first network equipment 10 is combined into configuration information with transmission direction information and type information, and configuration information is placed the control signaling.
Concrete configuration information can be type bitmap+ transmission direction bitmap; Type bitmap+ second sequence number; First sequence number+transmission direction bitmap; A kind of in first sequence number+second sequence number.
The sort of can in agreement, the regulation of concrete employing; Can also notify 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; Can first half be transmission direction bitmap also, 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 be directly the type information of each subframe and transmission direction information be used more than a bit information to be notified to adjacent sub-district.
Suppose that time span is 10ms (i.e. 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 fixedly subframes of variable subframe " 1 " expression, 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 " expression transmission direction is descending, and is then as shown in table 6:
Figure BDA0000052653830000121
Table 6
Concrete configuration information is 00000110100000011111.
Accordingly, after second network equipment 20 receives 00000110100000011111, according to just having known the type of each subframe and transmission direction according to the implication of the subframe of each bit correspondence among type bitmap and the transmission direction bitmap and each bit corresponding identification respectively.
Wherein, network equipment can also place in the following message one or more control signaling as required:
The cell ID of the cell ID of this sub-district, the PLMN of this sub-district (Public Land Mobile Network, Public Land Mobile Nerwork) sign and adjacent sub-district.
Second network equipment 20 is determined the type of each subframe in this sub-district radio frames according to the control signaling of the containing type information of receiving, then the subframe in this sub-district radio frames is configured.
Preferable, second network equipment 20 can also judge whether to detect this sub-district and the adjacent sub-district that sends control signaling between interference strength.
The interference strength here includes but not limited to down a kind of in the train value:
RSRP (Reference signal received power, Reference Signal Received Power) value, RIP (Received Interference Power, the interference received power) value, CQI (Channel QualityIndicator, the channel quality indication) value and RSRQ (Reference Signal Received Quality, Reference Signal Received Quality) value.
During interference strength between the adjacent sub-district of determining to detect this sub-district and sending control signaling, Pei Zhi subframe is variable subframe in adjacent sub-district if desired, and then second network equipment 20 does not use this subframe or reduces the use priority of this subframe.
Concrete, second network equipment 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 the control signaling comprises transmission direction information, and the interference strength between the adjacent sub-district of determining to detect this sub-district and sending control signaling, when Pei Zhi subframe was variable subframe in adjacent sub-district if desired, the subframe type that second network equipment 20 can dispose was identical with the subframe type and the transmission direction of same subframe sign in the adjacent sub-district with transmission direction.
Such as subframe 7 and subframe 8 are variable subframes, then the subframe 7 of this sub-district can be configured to the transmission direction identical with the subframe 7 of adjacent sub-district; The subframe 8 of this sub-district is configured to the transmission direction identical with the subframe 8 of adjacent sub-district.
Interference strength between the adjacent sub-district of determining to detect this sub-district and sending control signaling, Pei Zhi subframe is fixing subframe in adjacent sub-district if desired, and the subframe type that second network equipment 20 can dispose is identical with the subframe type and the transmission direction of same subframe sign in the adjacent sub-district with transmission direction.
Because fixedly the transmission direction of subframe can be determined according to predefined information or uplink-downlink configuration information,, also can know the fixedly transmission direction of subframe if do not comprise transmission direction information in the control signaling.Certainly, if comprise transmission direction information in the control signaling, then be as the criterion with the transmission direction information in the control signaling.
Wherein, if the interference strength between second network equipment, the 20 definite adjacent sub-districts that can detect this sub-district and send control signaling then further compares interference strength and threshold value.The setting of concrete threshold value can rule of thumb be worth or simulation result is stipulated in agreement or notified by high level.The threshold value that different interference strengths is corresponding different.
If interference strength is not less than threshold value, and when needing the subframe of configuration to be variable subframe in adjacent sub-district, second network equipment 20 does not use this subframe or reduces the use priority of this subframe.Do not use the concrete mode of subframe identical, do not repeat them here with the above-mentioned mode of subframe of not using.
If interference strength is not less than threshold value, no matter be variable subframe or fixing subframe, second network equipment 20 can be configured the subframe in this sub-district radio frames according to default configuration information, or the subframe in this sub-district radio frames is configured according to the unified configuration information that network side issues, or when control also comprises transmission direction information in the signaling, the subframe in this sub-district radio frames is configured according to the control signaling of receiving.
If interference strength is less than threshold value, no matter be variable subframe or fixing subframe, second network equipment 20 independently is configured the subframe in this sub-district radio frames.

Variable subframe is that can carry out as required can dynamic-configuration.It is descending to be such as current period that the up next cycle just might become, and fixedly subframe is the subframe that transmission direction can not change.
In the 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 are provided with in the certain hour length fixedly first sign of subframe corresponding bit position in type bitmap (bit map), and second sign that the corresponding bit position in type bitmap of variable subframe in the time span is set, and with type bitmap as type information.
In force, type bitmap can only represent in the certain hour length the fixedly type information of subframe.
Suppose that time span is 10ms (i.e. radio frames length), subframe 0, subframe 1, subframe 2, subframe 5, subframe 6 and subframe 7 are fixing subframes." 1 " expression is subframe fixedly, and " 0 " represents variable subframe, and is then 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 the certain hour length.
Suppose that time span is 10ms (i.e. radio frames length), subframe 3, subframe 4, subframe 8 and subframe 9 are variable subframes." 1 " expression is subframe fixedly, and " 0 " represents variable subframe, and is then 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 the duration of setting be upgraded as required.
Particular type bitmap represents that the implication of the subframe of which subframe, each bit correspondence and each bit sign can stipulate in agreement, can also be notified by high level.
Mode two, network equipment be according to the corresponding relation of the type configuration pattern and first sequence number, determine first sequence number of the type configuration pattern correspondence of fixedly subframe in the certain hour length and variable subframe, and first sequence number that will determine is as type information.

The corresponding relation of the type configuration pattern and first sequence number can be stipulated in agreement in advance, also can be notified by high level.Can also the corresponding relation of configuration format and sequence number be upgraded as required.
Since when being not dynamic assignment, uplink-downlink configuration information that network interface is mutual.Therefore, if notify certain subframe to be fixing subframe in force, the indicated implication of its transmission direction and 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.
Preferable, network equipment can also place transmission direction information the control signaling.Each subframe of transmission direction information representation is uplink or downlink transfer
Concrete, in the step 501, network equipment can also be determined transmission direction information according to the subframe in the radio frames of this cell configuration.
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 are provided with in the certain hour length fixedly the 3rd sign of subframe corresponding bit position in transmission direction bitmap, and the 4th sign that variable subframe corresponding bit position in transmission direction bitmap in the time span is set, and with transmission direction bitmap as transmission direction information.
Suppose that time span is 10ms (i.e. radio frames length).The transmission direction of subframe 2, subframe 7, subframe 8 and subframe 9 is up." 1 " expression transmission direction is up, and " 0 " expression transmission direction is descending, and then 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 the duration of setting be upgraded as required.
Concrete transmission direction bitmap represents that the subframe of which subframe, each bit correspondence and the implication of each bit sign can stipulate in agreement, can also be notified by high level.
Mode two, network equipment are according to the corresponding relation of the transmission direction configuration format and second sequence number, determine second sequence number of the transmission direction configuration format correspondence of fixedly subframe in the certain hour length and variable subframe, and second sequence number that will determine is as transmission direction information.
The corresponding relation of the transmission direction configuration format and second sequence number can be referring to table 5.
Suppose that time span is 10ms (i.e. 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.Just can determine that according to table 5 first sequence number is 3.
The corresponding relation of the type configuration pattern and first sequence number can be stipulated in agreement in advance, also can be notified by high level.Can also the corresponding relation of configuration format and sequence number be upgraded as required.
In the step 502, network equipment can send with type information transmission direction information by two different control signalings; Also transmission direction information and type information all can be placed same control signaling.
If network equipment all places same control signaling with transmission direction information and type information, then network equipment is combined into configuration information with transmission direction information and type information, and configuration information is placed the control signaling.
Concrete configuration information can be type bitmap+ transmission direction bitmap; Type bitmap+ second sequence number; First sequence number+transmission direction bitmap; A kind of in first sequence number+second sequence number.
The sort of can in agreement, the regulation of concrete employing; Can also notify 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; Can first half be transmission direction bitmap also, 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 be directly the type information of each subframe and transmission direction information be used more than a bit information to be notified to adjacent sub-district.
Suppose that time span is 10ms (i.e. 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 fixedly subframes of variable subframe " 1 " expression, 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 " expression transmission direction is descending, and is then as shown in table 6.Concrete configuration information is 00000110100000011111.
