Embodiment 2
The embodiment of the present application provides a kind of method for transmitting signals, as shown in figure 4, including：
401, first node is configured to effective subframe group of carrying specified upstream signal.Wherein, each effective son Frame group is made of M continuous subframes, and M is positive integer；The specified upstream signal includes the uplink for belonging to the first node Signal or the uplink signal for belonging to second node.
Wherein, the first node and the second node serve the UE simultaneously, for carrying the first node Uplink signal effective subframe group and the uplink signal for carrying the second node effective subframe group it is different.First segment Point can be that the uplink signal of this section point configures effective subframe group, i.e. specified upstream signal includes the uplink for belonging to first node Signal, alternatively, the uplink signal that first node may be other nodes configures effective subframe group, i.e. specified upstream signal includes Belong to the uplink signal of second node.Referred to herein as second node indicates first primarily to being distinguished with first node Node and second node are two different nodes.For example, first node can be macro base station, second node can be micro- base It stands.Because the performance of macro base station is generally more powerful than micro-base station, it is possible to be configured for micro-base station using the powerful performance of macro base station Effective subframe group.Alternatively, first node and second node can be micro-base station simultaneously, effectively son is carried out by one of micro-base station The configuration of frame group.
It should be noted that M continuous subframes in each effectively subframe group are described specific comprising that can be used for UE transmissions The sub-frame of uplink of row signal.For FDD system, descending carrier and up-link carrier are located at different frequency ranges, the institute on up-link carrier It is sub-frame of uplink to have subframe all, therefore M continuous subframes can be used for UE and send specified upstream signal；For TDD system, downlink Carrier wave and up-link carrier are located at identical frequency range, only have part subframe for sub-frame of uplink on up-link carrier, therefore M continuous subframes In some or all of subframe can be used for UE send specified upstream signal.
Wherein, the up-link carrier of node, that is, specially appointed up-link carrier, for example, as shown in figure 4, wirelessly communicating There are 2 up-link carriers in system, up-link carrier 1 is a specified up-link carrier for the node.The node can be A node being arbitrarily designated in wireless communication system, such as the node can be micro-base station or may be macro base station. The uplink signal includes up channel, such as PUSCH, PUCCH and PRACH, can also include uplink reference signals, such as DMRS and SRS.
In FDD system, it is preferable that an effective subframe group is made of 5 or 4 continuous subframes.For example, such as Fig. 5 Shown, 5 continuous subframes are an effective subframe group, and 10 continuous subframes form an assignment period.Up-link carrier 1 and uplink Effective subframe pattern of carrier wave 2 is offset from each other.In this way, in each assignment period, UE can be in first effective subframe Group sends the uplink signal for being carried on up-link carrier 1, and the upper line number for being carried on up-link carrier 2 is sent in second effective subframe group According to.Alternatively, macro base station and micro-base station are to provide two specified nodes of service, effective subframe of macro base station for the same UE simultaneously Pattern and effective subframe pattern of micro-base station mutually stagger.In this way, in each assignment period, UE can be effectively sub at first Frame group sends the uplink signal for belonging to macro base station, and the upstream data for belonging to small base station is sent in second effective subframe group.
In a tdd system, it is preferred that when downlink becomes uplink transfer point period (downlink-to-uplink switch- Point periodicity) be 5 milliseconds when, an effective subframe group can be made of 5 continuous subframes；When downlink becomes uplink When the transfer point period is 10 milliseconds, an effective subframe group can be made of 10 continuous subframes.Alternatively, when uplink-downlink configuration is 0,1 or 2 when, an effective subframe group can be made of 5 continuous subframes；When uplink-downlink configuration is 3,4,5 or 6, one has Effect subframe group can be made of 10 continuous subframes.Wherein, uplink-downlink configuration and downlink become the specific of uplink transfer point period and match Setting situation can be with reference table 1.For example, as shown in fig. 6, by taking uplink-downlink configuration 1 as an example, 5 continuous subframes form an effectively son Frame group, 10 continuous subframes are an assignment period.Wherein D is downlink subframe, and S is special subframe, and U is sub-frame of uplink.In this way, In each assignment period, UE can send in the sub-frame of uplink in first effective subframe group and be carried on the upper of up-link carrier 1 Row data, the sub-frame of uplink in second effective subframe group send the upstream data for being carried on up-link carrier 2.Macro base station and micro- Base station is two specified nodes for providing service for the same UE simultaneously, effective subframe pattern of macro base station and micro-base station it is effective Subframe pattern mutually staggers.In this way, in each assignment period, UE can be sent out in the sub-frame of uplink in first effective subframe group The uplink signal for belonging to macro base station is sent, the sub-frame of uplink in second effective subframe group sends the uplink for belonging to micro-base station Data.
402, first node sends the configuration information of effective subframe group to UE, so that the UE matches confidence described It ceases in effective subframe group of instruction and sends the specified upstream signal.
In the present embodiment, the configuration information of effective subframe group may include effective subframe pattern and/or effective subframe pattern Entry-into-force time/duration.First node can notify effective subframe pattern of UE by high-level signaling, and configuration UE can only Sub-frame of uplink in effective subframe group sends specified upstream signal.High-level signaling (High Layer Signaling) is For opposite physical layer signaling, the signaling slower from higher level (layer) transmission frequency, including wireless heterogeneous networks (RRC, Radio Resource Control) signaling and media access control (MAC, Media Access Control) signaling Deng.Specifically, which can be MAC signalings.Alternatively, the high-level signaling may be the dedicated RRC signaling of each UE, So as to which effective subframe pattern of each UE is separately configured.Alternatively, the high-level signaling can also be broadcast signaling, it is present in master Block of information (MIB, Master Information Block) and/or system information block (SIB, System Information Block) inner, can effective subframe pattern uniformly be carried out to the UE in cell in this way and configured.
Configuring effective subframe group can be realized by configuring effective subframe pattern case.Wherein, effective subframe pattern is for referring to Show the distribution situation of effective subframe group in an assignment period, UE is selected when sending uplink signal in effective subframe group Sub-frame of uplink.Specifically, first node configures continuous subframe group, and a subframe group is made of M continuous subframes, one point Be made of, i.e., be made of K × M subframe K subframe group with the period, when it is K × M milliseconds a length of, wherein M and K be positive integer.Have Effect subframe refers to that UE can send the subframe of specified upstream signal.Invalid subframe refers to that UE cannot send specified upstream signal Subframe.Effective subframe group refers to that UE can send the subframe group of specified upstream signal.Invalid subframe group refers to that UE cannot Send the subframe group of specified upstream signal.Effective subframe pattern indicates effective subframe group in K × M milliseconds of assignment periods.It changes It is that effective sub-frame of uplink meets (10 × n at mathematic(al) representationf+nsbf) mod (K × M)=a × M+m, wherein M indicates a son The number of sub-frames that frame group or effective subframe group include, the subframe group number that K one assignment period of expression includes, m ∈ 0 ..., M-1, M is the sub-frame of uplink in M continuous subframes in an effective subframe group, and a is the group of effective subframe group in an assignment period Number, a ∈ 0 ..., K-1.The group number of effective subframe group can be configured by effective subframe pattern.It should be noted that To different up-link carriers or different nodes, different effective subframe patterns can be configured.As long as first node does not re-match Effective subframe pattern is set or deactivates, effective subframe pattern in each assignment period is the same.
First node notifies effective subframe pattern can be by notifying M, K and a to realize.Specifically, first node is by matching Effective subframe group number of number of sub-frames (i.e. M) and/or an assignment period in confidence breath one effective subframe group of instruction is (i.e. K)；First node indicates effective subframe group in an assignment period (i.e. a), for example, the configuration information packet by configuration information Containing K bit, each bit indicates the attribute of a subframe group, i.e. the subframe group is invalid subframe group or effective subframe group, For example, " 0 " indicates that invalid subframe group, " 1 " indicate effective subframe group.K bit then indicate in an assignment period, K subframe The attribute of group.Alternatively, standard pre-defines N number of effective subframe pattern, then by configuration information instruction configuration be it is N number of effectively Which of subframe pattern.
Further alternative, first node can be configured with the entry-into-force time of effect subframe pattern.The configuration take-effective time Method can be：The System Frame Number (SFN, System Frame Number) that first node notice UE comes into force, i.e., effective subframe pattern The SFN that case comes into effect.The method of configuration take-effective time can also be：First node notice UE is receiving effective subframe pattern N number of subframe after configuration information or N number of millisecond, or feed back to first node effective subframe pattern configuration information be properly received after N number of subframe or N milliseconds, effective subframe pattern comes into effect.Wherein, N is the integer more than or equal to 0.By the configuration take-effective time, Can reduce or eliminate the fuzzy phase between base station and user equipment, improve the validity that uplink is sent, avoid extra interference, False retrieval or leakage hair.
Further alternative, first node can be configured with the duration (duration) of effect subframe group, when continuing Between least unit can be wireless frame level, a radio frames are 10ms.For example, first node configures effective subframe group 100 In a radio frames in effective or 50 radio frames effectively.Least unit can also be millisecond (ms) grade, for example, node configuration is effective Subframe group is effective in effective or 1000ms in 100ms.First node notifies duration or the standard of the effective subframe groups of UE Pre-define the duration of effective subframe group.When more than the duration, i.e., after effective subframe group configuration signal failure, UE is used Effective subframe group mode of acquiescence, such as the configuration mode of effective subframe group of acquiescence can be uplink in all subframe groups Frame is all effective sub-frame of uplink.
403, when the specified upstream signal includes belonging to the uplink signal of the first node, first node receives The specified upstream signal that the UE is sent in effective subframe group.
In a kind of application scenarios of the present embodiment, the specified upstream signal can be the corresponding ACK/NACK of PDSCH, Step 403 may comprise steps of 4031 and 4032：
4031, first node is in subframe n-kmPDSCH is sent to UE, and determines that UE sends the ACK/NACK of the PDSCH Sub-frame of uplink, wherein the kmFor the integer more than or equal to 4.
It is understood that when downlink transfer supports HARQ technologies, UE is receiving PDSCH (Physical Downlink Share Channel, Physical Downlink Shared Channel) after, the ACK/NACK information for feeding back the PDSCH is needed, it should ACK/NACK information indicates the reception result of PDSCH.When PDSCH receives correct, UE feeding back ACKs, when PDSCH receives mistake, UE Feed back NACK.At the feedback moment of ACK/NACK, if without Physical Uplink Shared Channel (Physical Uplink Share Channel, PUSCH) it needs to send, ACK/NACK is carried on PUCCH (Physical Uplink Control Channel, object Reason uplink control channel) on send.
Specifically, first node determines that the realization process that UE sends the subframe of the ACK/NACK of PDSCH can be：
First, first node is in subframe n-kmPDSCH, k are sent to the UEmFor the integer more than or equal to 4.Because of subframe It is time domain unit, so subframe n-kmWhat is represented is a moment.Subframe n-kmWhat is indicated is the kth that subframe n is counted forwardmHeight Frame, alternatively, subframe n is subframe n-kmThe kth delayedmA subframe.
Then, first node is according to the subframe n-k for sending PDSCHm, determine that the UE transmissions that UE has arranged with network side should The acquiescence subframe of the ACK/NACK of PDSCH is subframe n.It is worth noting that the network side in the application refer to first node and Network side where second node.The acquiescence subframe arranged is according between standard pre-defined PDSCH and ACK/NACK Timing determination, i.e., according to kmIt determines.Specifically, the kth after PDSCH is sentmA subframe is the acquiescence subframe arranged.It is right In FDD system, kmThe 4th subframe after=4, i.e. PDSCH are sent is the acquiescence subframe arranged.For TDD system, in difference Uplink-downlink configuration inside, kmIt is different, for example, table 2 shows that the PDSCH of each subframe under different configurations is corresponding The acquiescence subframe for sending its ACK/NACK of agreement.For example, for uplink-downlink configuration 0, work as n-kmWhen=1, i.e. first segment Point sends PDSCH, k in subframe 1m=6, in this way, can determine that UE is used to send its ACK/NACK with what network side had been arranged Acquiescence subframe n be subframe 7.
Table 2
Finally, the acquiescence subframe n that first node has been arranged according to UE and network side, determines that UE sends the ACK/ of the PDSCH The sub-frame of uplink of nack message.When the subframe n belongs to the sub-frame of uplink in effective subframe group, determine the UE in son Frame n sends the ACK/NACK information of the PDSCH；When the subframe n is not belonging to the sub-frame of uplink in effective subframe group, Determine that the UE sends the ACK/NACK information of the PDSCH in subframe n+k × M, the subframe n+k × M belongs to apart from subframe n Sub-frame of uplink in nearest effective subframe group, subframe n+k × M are kth × M subframes that subframe n is delayed.For example, for What uplink-downlink configuration 0, UE and network side had been arranged is subframe 7 for sending the acquiescence subframe n of ACK/NACK, but subframe 7 is not Belong to the sub-frame of uplink in effective subframe group.It is assumed that M=5, is the subframe 2 of next radio frames after subframe 7 delays 5 subframes, The subframe 2 of next radio frames is the sub-frame of uplink of effective subframe group, so determining that UE delays 5 subframes and sends PDSCH's ACK/NACK。
