Background technology
Third generation partner program (the3rd Generation Partnership Project, 3GPP) is in order to change
Kind Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS), has formulated tool
Having Long Term Evolution (Long Term Evolution, the LTE) system of better performance, it supports third generation partner program the
Eight versions (3GPP Rel-8) standard and/or third generation partner program the 9th version (3GPP Rel-9) standard, to meet
The user demand day by day increased.Long evolving system be considered to provide high transfer rate, low latent time, package optimization and
Improve power system capacity and a kind of new wave point of coverage and wireless network architecture, including by multiple evolved base stations
The evolved general land UTRAN (Evolved that (evolved Node-Bs, eNBs) is formed
Universal Terrestrial Radio Access Network, E-UTRAN), its one side and client (user
Equipment, UE) communicate, the core on the other hand controlled with process non-access layer (Non Access Stratum, NAS)
Heart networking communicates, and core network includes servo gateway (serving gateway) and mobile management unit
Entities such as (Mobility Management Entity, MME).
Advanced Long Term Evolution (LTE-advanced, LTE-A) system is evolved by long evolving system and is formed, and it includes carrier wave
Integrated (carrier aggregation, CA), coordinate multiple spot (coordinated multipoint, CoMP) transmit/receive with
And the advanced technology such as multiple-input and multiple-output (multiple-input multiple-output, MIMO), with the frequency range that extends, offer
Rapid translating power rating and lifting cell edges usefulness.In order to make the client in advanced long evolving system and evolved base
Platform can be in communication with each other, and client and evolved base station must support the standard formulated for advanced long evolving system,
Such as third generation partner program the tenth version (3GPP Rel-10) standard or the standard of more recent version.
Long evolving system/the advanced person being different from frequency division duplexing (frequency-division duplexing, FDD) is long
Phase evolution system, at long evolving system/advanced person's Long Term Evolution of time division duplex (time-division duplexing, TDD)
In system, in identical frequency band, the transmission direction of subframe (subframes) can differ.It is to say, according to third generation cooperation partner
Uplink (uplink, UL)/lower link (downlink, the DL) configuration (UL/DL of companion planning standard institute specification
Configuration), subframe can be divided into uplink subframe, lower link subframe and special subframe.
Refer to Fig. 1, it is subframe and the corresponding table 10 in corresponding direction thereof in uplink/lower isl configuration.Fig. 1 paints

Road configuration.It is difficult to mate fast-changing data stream owing to this kind is semi-statically configured (semi-static allocation)
(traffic) characteristic and environment, creates the space improving system effectiveness.Therefore, with less periodicity (e.g., less than 640
Millisecond) to change uplink/lower isl configuration be the subject under discussion in discussing at present.
It is said that in general, according to system information block kenel 1, conventional client can be set with a uplink/lower link group
State, this uplink/lower isl configuration also known by an advanced client (advanced UE), and this advanced person's client is then set
Surely there is another uplink/lower isl configuration.This another uplink/lower isl configuration is true group that evolved base station is operated
State, evolved base station can provide service (i.e. performing to transmit and/or receive) to give biography according to this another uplink/lower isl configuration
System client and advanced client.
But, when an advanced client is converted to one second uplink/lower link by one first uplink/lower isl configuration
During configuration (the true configuration that i.e. evolved base station is operated), advanced client may be according to the second uplink/lower chain
The lower link subframe that road configuration is judged transmits, or upper judged according to the second uplink/lower isl configuration
Link subframe is received.Owing to advanced client should carry out transmitting and entering in lower link subframe in uplink subframe
Row data receiver, conflicts thus produces.Additionally, due to conventional client does not know true configuration and evolved base station needs
Thering is provided backward compatibility, conventional client may lose the scheduling chance in a subframe.Specifically, when according to traditional client
The direction of the subframe that the uplink/lower isl configuration of end is judged is different from the direction of the subframe judged according to true configuration
Time, evolved base station may will not arrange conventional client transmit in this subframe or receive, thus produce conflict, enter
And affect the running of conventional client and network-side and waste Radio Resource.
Therefore, how to solve by uplink/lower isl configuration conversion or caused by uplink/lower isl configuration difference
Conflict be the subject under discussion urgently discussed and solve.

Refer to the flow chart that Fig. 4, Fig. 4 are the embodiment of the present invention one flow process 40.Flow process 40 is used in the network-side of Fig. 2,
It is used for processing resource distribution in either TDD mode, to communicate with conventional client.Flow process 40 can be compiled into program
Code 314, it comprises the following steps:
Step 400: start.
Step 402: as judged according to one first uplink/lower isl configuration (UL/DL configuration)
One direction of one subframe (subframe) of frame (frame) and the party judged according to one second uplink/lower isl configuration
When different, when this subframe judged according to this first uplink/lower isl configuration is a uplink subframe or work as root
This subframe judged according to this first uplink/lower isl configuration be link subframe but at least this wireless communication system one
When communicator can not perform a measurement by this subframe, setting the direction, wherein this first uplink/lower isl configuration is used for
This communicator and this second uplink/lower isl configuration are for this network-side.
Step 404: in the burst, carries out a transmission or reception with this communicator.
Step 406: terminate.
According to flow process 40, when a direction of a subframe of the frame judged according to one first uplink/lower isl configuration
Time different with the direction judged according to one second uplink/lower isl configuration, when according to this first uplink/lower link group
This subframe that state is judged is by during a uplink subframe or when this son judged according to this first uplink/lower isl configuration
Frame be link subframe but at least this wireless communication system a communicator can not by this subframe perform one measurement time, net
Network end can set the direction, and wherein this first uplink/lower isl configuration is used for communicator (traditional client as shown in Figure 2
End) and this second uplink/lower isl configuration for this network-side.Then, network-side, in this subframe, is carried out with communicator
Transmit or receive.In other words, if meeting one of which in above-mentioned condition, network-side can reset the direction of subframe.Wherein, on
Transmission or the reception stated can include a hybrid automatic repeat-request (hybrid automatic repeat request, HARQ)
Passback (feedback) and/or a uplink permit amount (UL grant), and it is according to this first uplink/lower isl configuration, by
At least one be performed at least one previous subframe of at least one previous frame had previously transmitted or had received and triggered.Should be noted
It is, when subframe is multimedia broadcast multicast service (Multimedia Broadcast Multicast Service, MBMS)
Frame (i.e. multimedia broadcasting Single Frequency Network (Multicast-Broadcast Single Frequency Network, MBSFN)
Frame) time, subframe is not useable for performing measurement.Therefore, communicator will not because of the difference between uplink/lower isl configuration,
Omit and transmit or receive, and still can normally operate.Additionally, the difference between uplink/lower isl configuration is for communicator institute
The impact caused also can be lowered.
It should be noted that the implementation of flow process 40 is not limited to the above.For example, the first uplink/under
Isl configuration can be a system information block kenel 1(System Information Block Type1, SIB1).In this situation
Under, communicator can be a conventional client, and it only can change or set the cochain of itself according to system information block kenel 1
Road/lower isl configuration.Additionally, when meeting one of them of above-mentioned condition, network-side can be by setting the direction of subframe as
The direction of the subframe of one uplink/lower isl configuration, sets the direction of subframe.It is noted that above-mentioned measurement can include
One channel condition information (channel state information, CSI) is measured, a RRM (radio
Resource management, RRM) measure or a Radio Link Management (radio link management, RLM) measurement.
Refer to Fig. 5, it is the signal that the embodiment of the present invention one has the sub-frame configuration of uplink/lower isl configuration conversion
Figure.As it is shown in figure 5, uplink/lower isl configuration 1 is for conventional client, uplink/lower isl configuration 2 is then for net
Network end (and advanced client).It is said that in general, conventional client does not know true configuration (i.e. uplink/lower isl configuration 2).?
In Fig. 5, the subframe of frame n+1 performs rule (such as receiving hybrid automatic repeat-request passback) the Shi Yi district of the reception triggered
The direction being shown in same string in territory 500 represents it.For example, according to uplink/lower isl configuration 1 in the subframe 2 of frame n+1
The reception of the triggering performed by corresponds to according to uplink/lower isl configuration 1 institute in the subframe 5 and/or subframe 6 of frame n
The transmission performed.But, only can perform due to network-side to receive and according to uplink/lower isl configuration 2 in uplink subframe
The subframe 3 of the frame n+1 judged is lower link subframe (as shown in region 502 in Fig. 5), if conventional client performs a triggering
Transmitting (transmission i.e. triggered by the reception being performed in the subframe 9 of frame n), it is corresponding to according to uplink/lower isl configuration 1
In the reception that the subframe 9 of frame n is performed, this transmission triggered will not be received by network-side.In this situation, network-side can
According to the present invention (i.e. according to first condition of step 402), the subframe 3 of frame n+1 is considered as uplink subframe.It is to say,
The subframe 3 of frame n+1 can be set as uplink subframe by network-side, so that performed by conventional client in the subframe 3 of frame n+1
The transmission triggered can be received by network-side.Consequently, it is possible to because network-side and conventional client have different uplink/lower chains
Road configuration and the conflict that produces can achieve a solution, and network-side and conventional client can normally operate.
Refer to Fig. 6, it is the signal that the embodiment of the present invention one has the sub-frame configuration of uplink/lower isl configuration conversion
Figure.As shown in Figure 6, uplink/lower isl configuration 3 is for conventional client, and uplink/lower isl configuration 4 is then for net
Network end (and advanced client).As a rule, conventional client does not know true configuration (i.e. uplink/lower isl configuration 4).By
The subframe 4 of the frame n receiving and being judged according to uplink/lower isl configuration 4 only can be performed in uplink subframe in network-side
For lower link subframe, if conventional client performs a transmission according to uplink/lower isl configuration 3 in the subframe 4 of frame n, this passes
Send and will not be received by network-side.In this situation, network-side can be according to the present invention (i.e. according to first bar of step 402
Part), the subframe 4 of frame n is considered as uplink subframe.It is to say, the subframe 4 of frame n can be set as uplink subframe by network-side,
So that the transmission of the triggering performed by conventional client in the subframe 4 of frame n+1 can be received by network-side.Consequently, it is possible to because of
The conflict that network-side and conventional client have different uplink/lower isl configurations and produce can achieve a solution, network-side and
Conventional client can normally operate.
Refer to the flow chart that Fig. 7, Fig. 7 are the embodiment of the present invention one flow process 70.Flow process 70 is used in the network-side of Fig. 2,
It is used for processing resource distribution in either TDD mode.Flow process 70 can be compiled into program code 314, and it comprises the following steps:
Step 700: start.
Step 702: setting a system information block kenel 1 is a uplink/lower isl configuration 1(UL/DL
Configuration1).
Step 704: set the subframe of link of this uplink/lower isl configuration 1 as being not useable for and perform a survey
One subframe type of amount.
Step 706: terminate.
According to flow process 70, a system information block kenel 1 is set as a uplink/lower isl configuration 1 by network-side, and sets
The subframe of link the most once determining uplink/lower isl configuration 1 is the subframe type being not useable for performing a measurement.Namely
Saying, owing to system information block kenel 1 is generally used for conventional client, network-side is then to be configured by uplink/lower isl configuration 1
Give conventional client.Additionally, a subframe 4 of uplink/lower isl configuration 1 may be set as being not useable for performing by network-side
The subframe type measured.In another embodiment, network-side may be by the subframe 4 of uplink/lower isl configuration and a subframe 9
It is set as the subframe type being not useable for performing to measure.In other words, subframe 4 and subframe 9 all should not be used to perform measurement.Wherein,
Measurement can include that a channel condition information is measured, a RRM measures or a Radio Link Management is measured.When setting one
When subframe (such as subframe 4 and/or subframe 9) is the subframe being not useable for performing to measure, this subframe can be set as more than one by network-side
Media broadcast multicast services (Multimedia Broadcast Multicast Service, MBMS) subframe.On consequently, it is possible to
The impact that difference between link/lower isl configuration is caused for conventional client can be lowered.
If it should be noted that, subframe 9 is set as that multimedia broadcast multicast service subframe (i.e. can not perform survey by network-side
The subframe of amount), conventional client, in addition to can not performing to measure in subframe 9, also can not perform reception (i.e. in subframe 9
Receive lower link data).On the other hand, when network-side, subframe 9 is set as lower link subframe (can perform the subframe measured)
Time, if true configuration is non-for uplink/lower Link State 0, conventional client can perform to receive and measurement in subframe 9.But,
If true configuration is uplink/lower Link State 0(i.e. subframe 9 is uplink subframe), conventional client will not receive letter
Number and may measure terminate after obtain mistake result.Therefore, if configuration uplink/lower Link State 1 gives traditional client
End, under the worst situation, (i.e. subframe 4 and subframe 9 are all set to multimedia broadcast multicast service subframe and special subframe is non-
For transmitting lower link data), conventional client only can receive in subframe 0 and subframe 5 under link data.If only by subframe 4
Being set as multimedia broadcast multicast service subframe, conventional client can obtain one for performing subframe (the i.e. subframe received more
9), thus improve the output (throughput) of lower link.But, if true configuration is uplink/lower Link State 0, pass
System client will not receive signal and may obtain the result of mistake after measurement terminates.Therefore, designer must be
The accuracy catch cropping of lower link output and measurement is accepted or rejected.If it is noted that network-side triggers an aperiodicity channel status
Information report, the measurement result ignored in subframe 9, the measurement result compensated in subframe 9 or over-evaluate the measurement knot in subframe 9
Really, the accuracy of measurement still can obtain lifting.Further, it is used for performing State Transferring (i.e. traffic conformance in decision
(traffic adaption)) a uplink/lower Link State group time, network-side can be from uplink/lower Link State group
In group get rid of uplink/lower Link State 0, with avoid obtain mistake measurement result and promote under link subframe quantity (as
For transmitting/receive the quantity of the subframe of lower link data).
Refer to the flow chart that Fig. 8, Fig. 8 are the embodiment of the present invention one flow process 80.Flow process 80 is used in the network-side of Fig. 2,
It is used for selecting uplink/lower Link State in either TDD mode.Flow process 80 can be compiled into program code 314, and it includes
Following steps:
Step 800: start.
Step 802: determine a uplink/lower isl configuration of the communicator for this wireless communication system.
Step 804: when a subframe of multiple uplink/lower isl configuration is a uplink subframe, set this uplink/
The subframe of link once of lower isl configuration is the subframe type being not useable for performing a measurement, the most the plurality of uplink/under
Isl configuration is for performing this subframe of configuration conversion and the plurality of uplink/lower isl configuration corresponding to this uplink/lower chain
This lower link subframe of road configuration.
Step 806: terminate.
According to flow process 80, network-side be initially selected for wireless communication system a communicator (as conventional client and/
Or advanced client) a uplink/lower isl configuration.If it follows that a subframe of multiple uplink/lower isl configuration is one
Uplink subframe, the subframe of link once of this uplink/lower isl configuration is set as being not useable for performing a measurement by network-side
Subframe type, the most the plurality of uplink/lower isl configuration is used for performing configuration conversion (i.e. traffic conformance) and these are many
The subframe of individual uplink/lower isl configuration is corresponding to this lower link subframe of this uplink/lower isl configuration.For example, on
Link/lower isl configuration can be system information block kenel 1.It is to say, network-side determines for conventional client and does not holds
Uplink/lower the isl configuration of the advanced client of row configuration conversion.It is noted that above-mentioned measurement can include a channel shape
