Wherein, the adjacent sub-district here is co-frequency neighbor cell or iso-frequency adjacent community; And this sub-district and adjacent sub-district can be in the adjacent sub-district or the different TDD network of same TDD network.
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 the fixedly numerical value of subframe corresponding bit in type bitmap (bit map), and the numerical value that the corresponding bit 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:
Table 1
Concrete type bitmap 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 value corresponding.
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:
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 value corresponding.
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 subframe of which subframe, each bit correspondence and the implication of each bit numerical value 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 form and first sequence number, determine first sequence number of the type configuration form 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 form 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 2.
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 form 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 announcement information with transmission direction information.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 the fixedly numerical value of subframe corresponding bit in transmission direction bitmap, and the numerical value that the corresponding bit in transmission direction bitmap of variable subframe 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:
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 value corresponding.
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 numerical value 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.
(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 form 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 announcement informations; Also transmission direction information and type information all can be placed same announcement information.
If first network equipment 10 all places same announcement information 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 announcement information.
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:
Table 6
Concrete configuration information is 00000110100000011111.
Accordingly, after second network equipment 10 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 value corresponding respectively.
Wherein, network equipment can also place announcement information with in the following message one or more 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.
In force, first network equipment 10 can send to adjacent sub-district with notification message by direct communication interface or indirect communication interface.
For example having between the sub-district that X2 connects (as Macro (grand) sub-district, Pico sub-district etc.) can use X2 interface to send; Do not have between the sub-district that X2 interface connects (as the femto sub-district etc.) can use the S1 interface.
Wherein, second network equipment 20 judges whether to detect this sub-district and sends interference strength between the adjacent sub-district of announcement information.
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.
When the interference strength of determining to detect between the adjacent sub-district of this sub-district and transmission announcement information, 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 announcement information comprises transmission direction information, and the interference strength between the adjacent sub-district of determining to detect this sub-district and send announcement information, 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.
In the interference strength of determining between the adjacent sub-district that to detect this sub-district and send announcement information, 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, so if do not comprise transmission direction information in the announcement information, also can know the fixedly transmission direction of subframe.Certainly, if comprise transmission direction information in the announcement information, then be as the criterion with the transmission direction information in the announcement information.
Wherein, if the interference strength between the adjacent sub-district that second network equipment 20 is determined can detect this sub-district and send announcement information 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 in announcement information, also comprising transmission direction information, the subframe in this sub-district radio frames is configured according to the announcement information 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.
When autonomous configuration, second network equipment 20 can be considered a kind of in the situations such as business demand, channel load, terminal quantity, also can consider multiplely, as the case may be the subframe in this sub-district radio frames is configured then.
Overweight such as ascending load, can put sub-frame of uplink by polygamy; Downlink business is too much, can deposit capable subframe etc. by polygamy.
Need to prove that above-mentioned table 1～table 6 just illustrates, do not represent that the embodiment of the invention necessarily according to the content of table 1～table 6, also can not adopt the form and the content of table 1～table 6, and adopt other modes to realize.
Wherein, first network equipment 10 of the embodiment of the invention and second network equipment 20 can be base station (such as macro base stations, little base station, Home eNodeB etc.), also can be RN (relaying) equipment, can also be other network equipments.
Based on same inventive concept, the method of two kinds of network equipments and method of transmitting information and configuration subframe also is provided in the embodiment of the invention, because principle that these equipment and method are dealt with problems and the system similarity that disposes subframe, therefore the enforcement of these equipment and method can repeat part and repeat no more referring to the enforcement of method.

Wherein, information determination module 100 can be provided with in the certain hour length the fixedly numerical value of subframe corresponding bit in type bit bitmap bitmap, and the numerical value that the corresponding bit in type bitmap of variable subframe in the time span is set, and with type bitmap as type information; Or, determine first sequence number of the type configuration form correspondence of fixedly subframe in the certain hour length and variable subframe, and first sequence number that will determine is as type information according to the corresponding relation of the type configuration form and first sequence number.
Preferable, announcement information also comprises transmission direction information; Accordingly, information determination module 100 is determined transmission direction information according to the subframe in the radio frames of this cell configuration.
Wherein, information determination module 100 can be provided with in the certain hour length the fixedly numerical value of subframe corresponding bit in transmission direction bitmap, and the numerical value that the corresponding bit in transmission direction bitmap of variable subframe in the time span is set, and with transmission direction bitmap as transmission direction information; Or, 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 according to the corresponding relation of the transmission direction configuration format and second sequence number.
In force, information determination module 100 can also be combined into configuration information with transmission direction information and type information, and configuration information is placed announcement information.
Wherein, sending module 110 can send to adjacent sub-district with notification message by direct or indirect communication interface.
As shown in Figure 4, second of the embodiment of the invention kind of network equipment comprises: processing module 200 and configuration module 210.
Wherein, configuration module 210 can not detect this sub-district and send interference strength between the adjacent sub-district that interference strength between the adjacent sub-district of announcement information maybe can detect this sub-district and transmission announcement information, and when interference strength is not less than threshold value, Pei Zhi subframe is variable subframe in adjacent sub-district if desired, does not use this subframe or reduces the use priority of this subframe.
Concrete, configuration module 210 is mixed with MBSFN subframe or ABS subframe or sub-frame of uplink with obsolete subframe but does not carry out uplink scheduling.
If announcement information also comprises transmission direction information, configuration module 210 is in the time can not detecting this sub-district and send interference strength between the adjacent sub-district of announcement information, and same subframe identifies in the subframe type of configuration and transmission direction and the adjacent sub-district subframe type and transmission direction are identical.
Wherein, configuration module 210 can detect this sub-district and send interference strength between the adjacent sub-district of announcement information, and during the threshold value of interference strength sub-district, independently the subframe in this sub-district radio frames is configured; Interference strength between the adjacent sub-district that can detect this sub-district and transmission announcement information, and interference strength is not during the threshold value of sub-district, according to default configuration information the subframe in this sub-district radio frames is configured, or the subframe in this sub-district radio frames is configured according to the unified configuration information that network side issues, or when in announcement information, also comprising transmission direction information, the subframe in this sub-district radio frames is configured according to the announcement information of receiving.
In force, first kind of network equipment also may be as the recipient.Second kind of network equipment also may be as transmit leg, so the function of first network equipment and second network equipment can be combined in (promptly the module of first network equipment and second network equipment is in an entity) in the entity, select to use the function of first network equipment or the function of second network equipment as required.
As shown in Figure 5, embodiment of the invention method of transmitting information comprises the following steps:
The announcement information that step 502, network equipment will contain type information sends to adjacent sub-district.
Wherein, the adjacent sub-district here is co-frequency neighbor cell or iso-frequency adjacent community; And this sub-district and adjacent sub-district can be in the adjacent sub-district or the different TDD network of same TDD network.
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 the fixedly numerical value of subframe corresponding bit in type bitmap (bit map), and the numerical value that the corresponding bit 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 subframe of which subframe, each bit correspondence 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 the type configuration form and first sequence number, determine first sequence number of the type configuration form 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 form and first sequence number can be referring to table 3.
The corresponding relation of the type configuration form 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 announcement information with transmission direction information.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 the fixedly numerical value of subframe corresponding bit in transmission direction bitmap, and the numerical value that the corresponding bit in transmission direction bitmap of variable subframe 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 numerical value 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 form 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 announcement informations; Also transmission direction information and type information all can be placed same announcement information.
If network equipment all places same announcement information 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 announcement information.
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.
Wherein, network equipment can also place announcement information with in the following message one or more as required:
