Embodiment

Embodiment of the present invention network side passes through the TDD subscriber equipment transmission ascending-descending subframes configuration information of high-level signaling to evolution of user-specific; The TDD subscriber equipment of evolution carries out TDD radio frame transmission data according to the ascending-descending subframes configuration information from network side that the high-level signaling by user-specific receives.Because the invention process is user device configuration TDD ascending-descending subframes by high-level signaling, thus shorten the change cycle, business demand change can be adapted to; And do not need all frequent read system message again of all subscriber equipmenies in community, save the power consumption of subscriber equipment.

Wherein, the TDD subscriber equipment of evolution is the subscriber equipment of LTE Rel (version)-11 and later version.The TDD ascending-descending subframes configuration that the ascending-descending subframes configuration information sent by the high-level signaling of user-specific is corresponding can be the one (as shown in table 1) in the TDD ascending-descending subframes configuration specified in Rel-8, Rel-9 and Rel-10, also can be other new ascending-descending subframes configuration modes.

Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.

In declarative procedure below, first implement to be described from the cooperation of network side and user equipment side, finally be described from the enforcement of network side and user equipment side respectively, but this does not also mean that the two must coordinate enforcement, in fact, when network side and user equipment side separate implement time, also solve the problem respectively existing for network side, user equipment side, when just the two is combined, better technique effect can be obtained.

As shown in Figure 2, the system transmitting data in embodiment of the present invention TDD radio frames comprises: the TDD subscriber equipment 20 of network equipment 10 and evolution.

Network equipment 10, for determining the ascending-descending subframes configuration information of the TDD subscriber equipment 20 of evolution, and sends ascending-descending subframes configuration information by the high-level signaling of user-specific to the TDD subscriber equipment 20 of evolution, and by TDD radio frame transmission data;

The TDD subscriber equipment 20 of evolution, for the ascending-descending subframes configuration information from network equipment 10 that basis is received by the high-level signaling of user-specific, determine that TDD ascending-descending subframes configures, according to the ascending-descending subframes configuration determined, by TDD radio frame transmission data.

Preferably, network equipment 10 determines the ascending-descending subframes configuration information of the TDD subscriber equipment needing to send to this evolution according at least one in following message:

1, the TDD subscriber equipment of evolution and the practical business demand of network service;

2, the TDD subscriber equipment of evolution carries out the business demand amount of D2D (Device to Device communication, direct communication between user terminal);

3, the need of the up covering of the TDD subscriber equipment of enhancing evolution.

Wherein, in the TDD subscriber equipment of evolution and the practical business demand of network service, downlink data is that network equipment sends to subscriber equipment, and there are data to be sent the transmission buffering area of network side, judges traffic carrying capacity size thus; Upstream data amount size obtains according to the transmission buffer area data volume of terminal to report.

Wherein, the TDD subscriber equipment of evolution carries out in the business demand amount of D2D, can according to user equipment to report in the business demand amount of D2D, and the modes such as network side distribution are determined.

Such as, the ascending-descending subframes configuration information of the TDD subscriber equipment needing to send to this evolution is determined according to the practical business demand of the TDD subscriber equipment of evolution and network service (i.e. up-downgoing need business proportion).In Fig. 7, the downlink business demand that UE2 carries out D2D is larger, then can be the configuration 5 in UE2 allocation table 1; The up-downgoing business demand amount that UE3 carries out D2D is suitable, then can be the configuration 1 in UE3 allocation table 1.

Such as, the business demand amount (i.e. up-downgoing need business proportion) of carrying out D2D according to the TDD subscriber equipment of evolution determines the ascending-descending subframes configuration information of the TDD subscriber equipment needing to send to this evolution.In Fig. 7, UE2 is larger with the downlink business demand of network service, then can be the configuration 5 in UE2 allocation table 1; The up-downgoing business demand amount of UE3 and network service is suitable, then can be the configuration 1 in UE3 allocation table 1.

Such as, according to the up covering of the TDD subscriber equipment the need of enhancing evolution, determine the ascending-descending subframes configuration information of the TDD subscriber equipment needing to send to this evolution, then the embodiment of the present invention can solve the up covering problem of cell edge power limited users equipment.As shown in Figure 10, the descending and uplink service ratio of plot planning is 4: 1, and therefore the ascending-descending subframes of system broadcasts is configured to 2 in table 1 (i.e. DSUDDDSUDD).For cell edge power limited users equipment, UL subframe bundling (i.e. TTI bundling cannot be carried out according to this sub-frame allocation mode, the up coverage enhancement technology of one of LTE, transmit to promote transmission reliability by a packet is placed in the multiple sub-frame of uplink of continuous print, be applicable to the terminal of power limited, concrete grammar can see 3GPP TS36.213).Now network equipment 10 can configure this type of power limited users equipment and adopt up more sub-frame configuration mode, such as, in table 1 shown in figure 1 (i.e. DSUUDDSUUD), then this subscriber equipment conventionally can carry out UL subframe bundling and operates.When power limited users equipment is less, namely this execution mode ensure that the covering of power limited users equipment, does not change again the uplink-downlink configuration of whole community and the corresponding relation of business proportion, thus ensure that the utilance of ascending-descending subframes resource.

It should be noted that, the embodiment of the present invention is not limited to above-mentioned 3 kinds of modes, and other can determine to need to send to the mode of the ascending-descending subframes configuration information of the TDD subscriber equipment of this evolution to be all suitable for the embodiment of the present invention.

If according to business demand, determine the ascending-descending subframes configuration information of the TDD subscriber equipment needing to send to this evolution, owing to adopting different ascending-descending subframes configurations for different user devices in same community, adapt to the business demand of different user devices.

If according to the up covering of the TDD subscriber equipment the need of enhancing evolution, determine the ascending-descending subframes configuration information of the TDD subscriber equipment needing to send to this evolution, due to the up more sub-frame configuration of user equipment allocation by being cell edge, make this type of subscriber equipment can use UL subframebundling mode transmit ascending data, promote up covering, avoid the coverage requirement in order to a small amount of subscriber equipment in edge to affect the up-downgoing service resources ratio of whole community, promote resource utilization.

In force, the high-level signaling of the user-specific of carrying ascending-descending subframes configuration information has a lot, such as RRC (Radio Resource Control, wireless heterogeneous networks) signaling, MAC (Media AccessControl, medium education) signaling etc.

Preferably, network equipment 10 can send ascending-descending subframes configuration information when the TDD subscriber equipment 20 of evolution and network connect.

Because the demand of the TDD subscriber equipment 20 of evolution likely changes, so network equipment 10 can cycle or by modes such as high level triggerings, redefine the ascending-descending subframes configuration information of the TDD subscriber equipment 20 of evolution, if ascending-descending subframes configuration information changes, can be reconfigured by the high-level signaling of user-specific, send ascending-descending subframes configuration information as by high-level signaling reconstitution process.

In systems in which except the TDD subscriber equipment 20 of evolution, also have the TDD subscriber equipment of non-evolution, the TDD subscriber equipment of these non-evolution needs to configure ascending-descending subframes by system broadcasts.Concrete, network equipment 10 sends ascending-descending subframes configuration information, for the TDD user device configuration TDD ascending-descending subframes for non-evolution by system broadcasts.

Wherein, the TDD subscriber equipment of non-evolution is the subscriber equipment of LTE Rel-10 and version before.

Preferably, network equipment 10, according to the demand data amount (comprising the business demand amount with network traffic demand and/or D2D) of the TDD subscriber equipment of non-evolution and the TDD subscriber equipment of network communication data demand and/or evolution, determines the ascending-descending subframes configuration information needing to be sent by system broadcasts.

Such as, determine the ascending-descending subframes configuration information needing to be sent by system broadcasts according to the demand data amount of the TDD subscriber equipment 20 of non-evolution: the downlink business demand of the TDD subscriber equipment of non-evolution is larger, then can select the configuration that descending sub frame is many; The uplink service demand of the TDD subscriber equipment of non-evolution is larger, then can select the configuration that sub-frame of uplink is many, the configuration 0 in such as table 1.

Such as, determine the ascending-descending subframes configuration information needing to be sent by system broadcasts according to the demand data amount of the TDD subscriber equipment 20 of evolution: the downlink business demand of the TDD subscriber equipment 20 of evolution is larger, then can select the configuration that descending sub frame is many; The uplink service demand of the TDD subscriber equipment 20 of evolution is larger, then can select the configuration that sub-frame of uplink is many.

For the demand data amount of the TDD subscriber equipment according to non-evolution and the TDD subscriber equipment 20 of evolution demand data amount and determine that the mode of the ascending-descending subframes configuration information needing to be sent by system broadcasts has a variety of, such as with reference to the strategy of network side, can be configured with the TDD subscriber equipment demand of the TDD subscriber equipment of non-evolution or evolution.

Wherein, network equipment 10 needs in same subframe, send data or receive data.Such as network equipment 10, according to the ascending-descending subframes configuration information being handed down to subscriber equipment (comprising the TDD subscriber equipment of evolution and the TDD subscriber equipment of non-evolution), communicates with subscriber equipment.

For different user devices (all subscriber equipmenies namely in system (or community), comprise the TDD subscriber equipment of non-evolution and the TDD subscriber equipment of evolution) be assigned as the subframe in identical traffic direction, network equipment 10 adopts identical transmission direction.Such as subframe A is descending sub frame at different subscriber equipmenies, then the transmission direction network equipment 10 for subframe A also adopts descending.

Different user devices (that comprise non-evolution with subscriber equipment that is evolution) is assigned as to the subframe of different transmission direction, network equipment 10, according to the business demand amount of subscriber equipment, determines the transmission direction of subframe for network side different user devices being assigned as to different transmission direction.Concrete, network equipment 10, according to the business demand amount of each subscriber equipment, judge to need to be preferably which subscriber equipment service, and employing is transmitted with the subframe direction of this user device configuration.Such as subframe B is sub-frame of uplink for the subscriber equipment had, descending sub frame for the subscriber equipment had, and the business demand amount of subscriber equipment 1 is larger, determine that being preferably subscriber equipment 1 serves, subframe B is up for family equipment 1, then the transmission direction network equipment 10 for subframe A also adopts up.

Different user devices (that comprise non-evolution with subscriber equipment that is evolution) is assigned as to the subframe of different transmission direction, except the business demand amount determination transmission direction according to subscriber equipment, can also according to whether there being HARQ (the Hybrid Automatic Repeat reQuest not carrying out feeding back in community, hybrid automatic repeat-request) process, determine the transmission direction of subframe for network side different user devices being assigned as to different transmission direction.If such as there is the DL of one or more subscriber equipment (down link) HARQ transmission to need UL (down link) ACK/NACK to feed back, determine that corresponding one or more feedback subframe is sub-frame of uplink; Otherwise, if there is the UL HARQ transmission of one or more user to need DL ACK/NACK to feed back, determine that corresponding one or more feedback subframe is descending sub frame.

In force, when network equipment is by TDD radio frame transmission data, PDSCH (Physical Downlink Shared Channel can be passed through, physical down link sharing channel) send downlink data, and receive upstream data by PUSCH (Physical Uplink Shared Channel, physical uplink link shared channels).

Preferably, when the TDD subscriber equipment 20 of evolution is by TDD radio frame transmission data, receive data by the descending sub frame in TDD radio frames, and send data by the sub-frame of uplink in TDD radio frames.

Concrete, the TDD subscriber equipment 20 of evolution is being assigned as detection descending sub frame carrying out descending control signaling PDCCH for it; If detect, PDCCH is downlink scheduling, then the MCS format receiving data that the frequency domain resource according to downlink scheduling instruction in the descending sub frame of downlink scheduling instruction indicates with downlink scheduling; If detect, PDCCH is uplink scheduling, then the MCS format receiving data that the frequency domain resource according to uplink scheduling instruction in the descending sub frame of uplink scheduling instruction indicates with uplink scheduling.

The TDD subscriber equipment 20 of such as evolution carries out the blind Detecting of descending control signaling in pre-assigned PRB resource.If detect that PDCCH is DL grant (downlink scheduling), then according to the instruction of PDCCH in current downlink subframe and/or the upper specific frequency domain resource of follow-up one or more specific descending sub frame with specific MCS format receiving data (these are specific all determines according to PDCCH instruction, lower with); If detect that PDCCH is UL grant (uplink scheduling), then in follow-up one or more specified upstream subframe, specific frequency domain resource sends data with specific MCS form according to the instruction of PDCCH.

In force, if the TDD subscriber equipment 20 of evolution communicates with network, then the TDD subscriber equipment 20 of evolution by the downlink data of PDSCH reception from network side, and sends upstream data by PUSCH to network side.

If the TDD subscriber equipment of evolution 20 carries out D2D, then the TDD subscriber equipment 20 of evolution is when carrying out D2D, by the TDD subscriber equipment transmission data of sub-frame of uplink to other evolution, and receive the data from the TDD subscriber equipment of other evolution by descending sub frame.

In force, D2D can be carried out under network controls.Concrete, network equipment 10 is after determining that the TDD subscriber equipment of two evolution needs to carry out D2D, select a specific sub-frame, wherein specific sub-frame for need send data user device configuration be sub-frame of uplink, for need receive data user device configuration is descending sub frame; Network equipment 10 scheduling needs the TDD subscriber equipment of the evolution sending data to send data in specific sub-frame, and scheduling needs the TDD subscriber equipment of the evolution receiving data to receive data in specific sub-frame.

Such as, in Fig. 8 A, UE1 and UE2 is assigned to the configuration of different ascending-descending subframes, and network equipment 10 knows that this two UE needs to carry out D2D communication (knowing as by mode mutual etc. between subscriber equipment and network side).Then UE1 receives the UL grant that network equipment 10 sends and indicates it in subframe 8, send data (these data are the D2D data sending to UE2) with specific MCS in specific resources in subframe 4, and UE2 receives in subframe 8 the DL grant that network equipment 10 sends in present sub-frame, receive data on the same resource with identical MCS.Said process achieves the D2D communication of UE1 to UE2, and this communication completes under network controls.

Except carrying out D2D under network controls, can not also carry out D2D under network controls, two subscriber equipmenies namely carrying out D2D are directly selected to carry out D2D transmission in the subframe that the transmission direction of the subscriber equipment carrying out D2D is contrary.Such as, in Fig. 8 B, the signal that UE1 sends in subframe 8 is received in subframe 8 by UE2.

Preferably, network equipment 10 passes through TDD radio frames when transmitting feedback information, sub-frame of uplink for receiving feedback information receives the feedback information that corresponding data receives HARQ process, and on the descending sub frame sending feedback information, sends the feedback information that corresponding data sends HARQ process;

Accordingly, the TDD subscriber equipment 20 of evolution passes through TDD radio frames when transmitting feedback information, sub-frame of uplink for sending feedback information sends the feedback information that corresponding data receives HARQ process, and on the descending sub frame of receiving feedback information, receives the feedback information that corresponding data sends HARQ process.

Wherein, determine which subframe has a lot for the mode of transmitting feedback information, enumerate several below.
