Description

A kind of information reception, launching technique, equipment and communication system

Technical field

The present invention relates to the communications field, more particularly to a kind of message receiving method, equipment and communication system.

Background technology

In current LTE TDD systems, frame structure includes the subframe of three types（subframe）：Descending sub frame （DL subframe）, sub-frame of uplink（UL subframe）And special subframe（Special subframe）, wherein, Special Subframe includes ascending pilot channel time slot（UpPTS）, translation and protection time slot（GP）With downlink pilot frequency channel time slot （DwPTS）.

As shown in figure 1, being uplink-downlink configuration schematic diagram in 7 of frame structure in LTE TDD systems.On in 7 shown in Fig. 1 In downstream arrangements, UL subframe can be divided into following 4 class according to front and rear subframe type：

1st class UL subframe：Adjacent previous subframe is Special subframe, and adjacent latter subframe is DL Subframe, may be simply referred to as SUD classes.

2nd class UL subframe：Adjacent previous subframe is Special subframe, and adjacent latter subframe is UL Subframe, may be simply referred to as SUU classes.

3rd class UL subframe：Adjacent previous subframe is UL subframe, and adjacent latter subframe is DL Subframe, may be simply referred to as UUD classes；

4th class UL subframe：Adjacent previous subframe is UL subframe, and adjacent latter subframe is UL Subframe, may be simply referred to as UUU classes.

Generally, terminal（UE）Can be in UL subframe to base station（eNodeB）Information is sent, and UE will not be in UL Subframe receives the signal from eNodeB, still, on discussing in LTE Release12 in current 3GPP In the D2D communication technologys, two UE can realize the transmission of information in UL subframe.

The D2D（Device-to-Device, device-to-device）The communication technology is a kind of allows between UE by multiplexing The new technique that local resource is directly communicated, D2D technologies can increase frequency spectrum efficiency of cellular communication system, reduction terminal hair Power is penetrated, the problem of wireless communication system frequency spectrum resource is deficient is solved to a certain extent.

In the D2D communication technologys, a UE（Referred to as UE1）Can be in UL subframe to another UE（Referred to as UE2） Information is sent, accordingly, UE2 need to receive the information from UE1 in UL subframe.

By above-mentioned 4th class UL subframe come exemplified by carrying out D2D communications, as shown in Fig. 2 being occurred in that in uplink-downlink configuration Situation adjacent three UL subframe, it is assumed that UE1 sends D2D information on UL subframe2 to UE2, because UE2 is in UL All in emission state on subframe1 and UL subframe3, therefore, come if UE2 will be received on UL subframe2 From UE1 D2D information, then UE2 needs to be converted to the reception shape on UL subframe2 from UL subframe1 emission state State, afterwards, after UE2 finishes receiving the D2D information of UE1 transmittings on UL subframe2, UE2 is again from UL subframe2's Reception state is converted to UL subframe3 emission state.

As the 2nd class UL subframe and the 3rd class UL subframe with the 4th class UL subframe situation Similar, when carrying out D2D communications on the 2nd class UL subframe, UE2 needs to complete once from reception state to emission state Conversion, when carrying out D2D communications on the 3rd class UL subframe, UE2 needs to complete once from emission state to reception state Conversion.

When UE is changed to reception state from emission state, or from reception state change to emission state when, it may appear that UE Refractory period when sending and receiving state switches（Transmitter transient period, TTP）, when UE is changed from emission state During for reception state, the power of emitter can not be eliminated immediately in UE, but in the presence of the process that one is gradually reduced up to eliminating, In this process, UE is cisco unity malfunction；Similarly, when UE is changed to emission state from reception state, launch in UE Machine improves power to normal operating condition and is also required to a process, in this process, and UE is also cisco unity malfunction.Mesh Before, UE refractory period is usually no more than the conversion duration that 20us, i.e. UE be converted to reception state from emission state and is no more than 20us, The conversion duration that UE is converted to emission state from reception state is also no more than 20us.

In current LTE standard, UE from DL subframe reception state are transformed into UL subframe emission state Required conversion time is compensated by reducing the length of GP in Special subframe, such as in Fig. 2 for eNodeB and In UE2 uplink-downlink configuration, GP Configuration Values are reduced into 20.2135us（Refractory period more than UE）；And UE is from UL subframe Emission state be transformed into DL subframe reception state needed for conversion time compensated by TA offset, such as In Fig. 2 for eNodeB and UE2 uplink-downlink configuration in, the 20.2135us between UL subframe3 and DL subframe.

Above is the mode of refractory period is compensated when being communicated between UE and eNodeB, if UE2 will be in the UL shown in Fig. 2 The D2D information from UE1 is received in subframe2, then can come to configure conversion time for refractory period in such a way：

First single-carrier frequency division multiple access (Single-carrier Frequency-s of the UE1 in UL subframe2 Division Multiple Access, SC-FDMA) on symbol and last SC-FDMA symbol not to UE2 transmitting D2D letters Breath, but to UE2 transmitting D2D information on middle N-2 SC-FDMA symbols, accordingly, UE2 is by UL subframe2 the One SC-FDMA symbol is as the conversion time that reception state is converted to from emission state, by last in UL subframe2 Individual SC-FDMA symbols are as the conversion time that emission state is converted to from reception state, on middle N-2 SC-FDMA symbols Receive D2D information（The N is the SC-FDMA symbol quantities included in UL subframe）.

In current 3GPP standards, conventional cyclic prefix is being used（CP）When, 14 are included in a UL subframe SC-FDMA symbols, each SC-FDMA symbol lengths are 2192Ts, and wherein CP length is 144Ts, when using extension CP, one A length of 512Ts, wherein Ts=1/ when CP in 12 SC-FDMA symbols, each SC-FDMA symbols is included in UL subframe 30720ms。

Because 1 UL subframe length is 1ms, therefore, wherein the length of 1 SC-FDMA symbol is more than 20us, More than the conversion time needed for UE, UE State Transferring demand disclosure satisfy that.

If the previous UL subframe for two UL subframe that UE2 will be adjacent in the 2nd class UL subframe Upper reception D2D information, then can be by last SC-FDMA of previous UL subframe in two adjacent UL subframe Symbol is used as conversion time；If UE2 will in the 3rd class UL subframe two neighboring UL subframe latter UL D2D information is received on subframe, then can be by first of latter UL subframe in two adjacent UL subframe SC-FDMA symbols are used as conversion time.

In current D2D communication process, when there are at least two adjacent UL subframe（I.e. the 2nd, 3,4 class UL subframe）, it is necessary to take in UL subframe a SC-FDMA symbol as conversion time（For the 2nd, 3 class UL subframe）, or taking two SC-FDMA symbols in UL subframe is used as conversion time（For the 4th class UL subframe）, due at least needing to take at least one SC-FDMA symbol in UL subframe, cause UE in UL subframe The upper real resource for being used to receive D2D information is reduced, the problem of UL subframe wastings of resources occur.

Embodiment

In order to solve when D2D communicates, a UL subframes of the UE at least two adjacent UL subframe During upper reception D2D information, taking at least one SC-FDMA symbol causes the UL subframe wastings of resources as conversion time The problem of, it is long that proposition of the embodiment of the present invention opens up less than one SC-FDMA symbol in the UL subframe for receiving D2D information Degree but the conversion time not less than 20us, compared to current D2D communication process, due in the case where meeting UE State Transferrings The conversion time that UE is used to receive the UL subframe of D2D information is reduced, real use can be effectively increased on UL subframe In the resource for receiving D2D information, the wasting of resources is reduced.

With reference to specific embodiment, the present invention will be described in detail.

Embodiment one：

Assuming that in the scheme of embodiment one, UE2 receives the D2D from UE1 in the 2nd class UL subframe described in Fig. 1 Information, i.e. UE2 receive D2D information on two neighboring UL subframe previous UL subframe, the present embodiment one Concrete scheme is as shown in figure 3, comprise the following steps：

Step 101：UE2 determines final stage duration in previous UL subframe in two neighboring UL subframe T1, the t1 are less than a SC-FDMA symbol lengths in UL subframe, and not less than 20us.

Step 102：UE2 regard the t1 as the conversion time that emission state is converted to from reception state.

Because UE2 is received on the previous UL subframe in the 2nd class UL subframe described in Fig. 1 from UE1 D2D information, therefore, after UE2 has received D2D information on the previous UL subframe, and a UL after entering , it is necessary to be converted to emission state from reception state before subframe, therefore, in the UL subframe for receiving D2D information Last part opens up t1, the conversion as status information, because t1 length is not less than 20us, therefore, it is possible to meet UE2's State Transferring demand；Simultaneously as t1 length is less than a SC-FDMA symbol lengths, compared to the conversion shown in current Fig. 2 Process, can obviously reduce the UL subframe resources shared by conversion time.

Step 103：UE2 is received on other time interval resources in the previous UL subframe in addition to t1 from UE1 D2D signals.

Step 104：UE2 will receive shape after D2D signals are received in the t1 of the previous UL subframe State is converted to emission state.

It is corresponding with above-mentioned UE2 reception D2D information processes, the side that UE1 launches D2D information is also included in the present embodiment one Method, it is assumed that UE1 launches D2D in the 2nd class UL subframe on two neighboring UL subframe previous UL subframe Information, still with as shown in figure 3, comprising the following steps：

Step 201：UE1 determines final stage duration in previous UL subframe in two neighboring UL subframe T1, the t1 are less than a SC-FDMA symbol lengths in UL subframe, and not less than 20us.

The t1 that UE1 is determined is identical with the t1 that UE2 is determined.

Step 202：UE1 launches on other time interval resources in the previous UL subframe in addition to t1 to UE2 D2D signals.

In this step 202, UE1 launches D2D information on the previous UL subframe to UE2, when entering UL After subframe final stage duration t1, stop transmitting D2D information, in order to which UE2 can carry out State Transferring in t1.

The method of embodiment one is illustrated below by a specific example.

Example 1,

As shown in figure 4, so that the 2nd class UL subframe and UL subframe are using routine CP as an example, eNodeB, UE1 and UE2 is to time interval resource configuration information schematic diagram, as can be seen from Figure 4：

UE2 as D2D information recipient, opened up on UL subframe1 final stage duration t1=1120*Ts= 36.7583us.Other time interval resources in UL subframe1 in addition to t1 are divided into 13 SC-FDMA symbols, because t1 takes Length be less than the SC-FDMA symbols of standard, therefore, 13 SC-FDMA symbol lengths after division are more than the SC- of standard FDMA symbols, can be by each SC-FDMA symbol lengths after division in order to match in being transmitted in D2D with existing standard 2048*Ts=66.67us（The resource of carrying information i.e. in standard SC-FDMA symbols）As the resource of carrying D2D information, it will draw Point after each SC-FDMA symbols in remaining resource as CP in the SC-FDMA length（More than CP in standard SC-FDMA Length 144*Ts=4.6875us）.

With Fig. 4 situations similarly, if UL subframe are using other in CP, UL subframe1 in addition to t1 are extended Gap resource is divided into 11 SC-FDMA symbols, and each SC-FDMA symbol lengths after division are more than the SC-FDMA symbols of standard Length, sets identical with standard SC-FDMA symbols by the resource of carrying information in each SC-FDMA symbol lengths after division, Surplus resources are used as the length as CP in the SC-FDMA symbols after dividing after division（More than the length of CP in standard SC-FDMA Spend 512*Ts）.

With UE2 similarly, UE1 also opens up final stage duration as the launch party of D2D information on UL subframe1 t1=1120*Ts=36.7583us.The dividing mode of other time interval resources in UL subframe1 in addition to t1 is similar with UE2's.

Embodiment two：

Assuming that in the scheme of embodiment two, UE2 receives the D2D from UE1 in the 3rd class UL subframe described in Fig. 1 Information, i.e. UE2 receive D2D information on two neighboring UL subframe latter UL subframe, the present embodiment two Concrete scheme is as shown in figure 5, comprise the following steps：

Step 301：UE2 determines to originate one section of duration in latter UL subframe in two neighboring UL subframe T2, the t2 are less than a SC-FDMA symbol lengths in UL subframe, and not less than 20us.

Step 302：UE2 regard the t2 as the conversion time that reception state is converted to from emission state.

Because UE2 is received on the latter UL subframe in the 3rd class UL subframe described in Fig. 1 from UE1 D2D information, therefore, UE2 performed on previous UL subframe transmitting operation after, latter UL need to passed through Subframe is received before D2D information, and reception state is converted to from emission state.Therefore, the UL of D2D information is being received Start-up portion in subframe opens up t2, the conversion as status information, because t2 length is not less than 20us, therefore, it is possible to Meet UE2 State Transferring demand；Simultaneously as t2 length is less than a SC-FDMA symbol lengths, compared to current Fig. 2 Shown transfer process, can obviously reduce the UL subframe resources shared by conversion time.

Step 303：UE2 is on previous UL subframe after transmitting information, in latter UL subframe t2 Emission state is converted into reception state.

Step 304：Received on other time interval resources of UE2 in the rear in a UL subframe in addition to t2 and come from UE1 D2D signals.

It is corresponding with above-mentioned UE2 reception D2D information processes, the side that UE1 launches D2D information is also included in the present embodiment two Method, it is assumed that UE1 also launches in the 3rd class UL subframe on two neighboring UL subframe latter UL subframe D2D information, still with as shown in figure 5, comprising the following steps：

Step 401：UE1 determines to originate one section of duration in latter UL subframe in two neighboring UL subframe T2, the t2 are less than a SC-FDMA symbol lengths in UL subframe, and not less than 20us.

The t2 that UE1 is determined is identical with the t2 that UE2 is determined.

Step 402：Launch on other time interval resources of UE1 in the rear in a UL subframe in addition to t2 to UE2 D2D signals.

In this step 402, UE1 does not launch D2D information when entering the latter UL subframe to UE2, works as t2 After end, launch D2D information to UE2, in order to which UE2 can carry out State Transferring in t2.

The method of embodiment two is illustrated below by a specific example.

Example 2,

As shown in fig. 6, so that the 3rd class UL subframe and UL subframe are using routine CP as an example, eNodeB, UE1 and UE2 is to time interval resource configuration information schematic diagram, as can be seen from Figure 6：

UE2 as D2D information recipient, UL subframe2 one section of duration t2=1104*Ts of starting= 35.9375us.Other time interval resources in UL subframe2 in addition to t2 are divided into 13 SC-FDMA symbols, because t2 takes Length be less than the SC-FDMA symbols of standard, therefore, 13 SC-FDMA symbol lengths after division are more than the SC- of standard FDMA symbols, can be by each SC-FDMA symbol lengths after division in order to match in being transmitted in D2D with existing standard 2048*Ts=66.67us（The resource of carrying information i.e. in standard SC-FDMA symbols）As the resource of carrying D2D information, it will draw Point after each SC-FDMA symbols in remaining resource as CP in the SC-FDMA length（More than CP in standard SC-FDMA Length 144*Ts=4.6875us）.

With Fig. 6 situations similarly, if UL subframe are using other in CP, UL subframe2 in addition to t2 are extended Gap resource is divided into 11 SC-FDMA symbols, and each SC-FDMA symbol lengths after division are more than the SC-FDMA symbols of standard Length, sets identical with standard SC-FDMA symbols by the resource of carrying information in each SC-FDMA symbol lengths after division, Surplus resources are used as the length as CP in the SC-FDMA symbols after dividing after division（More than the length of CP in standard SC-FDMA Spend 512*Ts）.

With UE2 similarly, UE1 also opens up one section of duration of starting as the launch party of D2D information on UL subframe2 t2=1104*Ts=35.9375us.The dividing mode of other time interval resources in UL subframe2 in addition to t2 is similar with UE2's.

Embodiment three：

Assuming that in the scheme of embodiment three, UE2 is received from UE1's on the 4th class UL subframe described in Fig. 1 D2D information, i.e. UE2 receive D2D information, the present embodiment on three UL subframe of adjacent continuous middle UL subframe Three concrete scheme is as shown in fig. 7, comprises following steps：

Step 501：UE2 is determined last one in middle UL subframe in adjacent continuous three UL subframe Duan Shichang t1 and one section of duration t2 of starting, the SC-FDMA symbol that the t1 and t2 are respectively smaller than in UL subframe is long Degree, and all it is not less than 20us.

Step 502：UE2 as the conversion time that emission state is converted to from reception state, the t2 is made the t1 To be converted to the conversion time of reception state from emission state.

Because UE2 is received from UE1's on the middle UL subframe in the 4th class UL subframe described in Fig. 1 D2D information, therefore, UE2 are performed on previous UL subframe after transmitting operation, need to be connect by middle UL subframe Receive before D2D information, reception state is converted to from emission state.Therefore, rising in the UL subframe for receiving D2D information T2 is opened up in initial portion, the conversion as status information.In addition, UE2 has received D2D information on the middle UL subframe Afterwards, and after entering before a UL subframe, it is necessary to emission state is converted to from reception state, therefore, in reception D2D Last part in the UL subframe of information opens up t1, the conversion as status information.

Because t1 and t2 length is all not less than 20us, therefore, it is possible to meet UE2 State Transferring demand；Simultaneously as T1 and t2 length is both less than a SC-FDMA symbol lengths, compared to the transfer process shown in current Fig. 2, can obviously reduce UL subframe resources shared by conversion time.

Step 503：UE2 after transmitting information, is incited somebody to action on previous UL subframe in middle UL subframe t2 Emission state is converted to reception state.

Step 504：UE2 is received on other time interval resources in the middle UL subframe in addition to t1 and t2 and come from UE1 D2D signals.

Step 505：UE2 is after D2D signals are received, by reception state in the t1 of the middle UL subframe Emission state is converted to, and enters latter UL subframe.

It is corresponding with above-mentioned UE2 reception D2D information processes, the side that UE1 launches D2D information is also included in the present embodiment three Method, it is assumed that UE1 is also on continuous three UL subframe adjacent in the 4th class UL subframe middle UL subframe Launch D2D information, still with as shown in fig. 7, comprises following steps：

Step 601：UE1 is determined last one in middle UL subframe in adjacent continuous three UL subframe Duan Shichang t1 and one section of duration t2 of starting, the SC-FDMA symbol that the t1 and t2 are respectively smaller than in UL subframe is long Degree, and all it is not less than 20us.

The t1 that UE1 is determined is identical with t2 with the UE2 t1 determined with t2.

Step 602：UE1 launches on other time interval resources in the middle UL subframe in addition to t1 and t2 to UE2 D2D signals.

UE2 is as the recipient of D2D information, final stage duration t1, one section of duration t2 of starting in UL subframe2 Open up after conversion time, other time interval resources in UL subframe2 in addition to t1 and t2 are divided to 13 obtained SC-FDMA Symbol lengths are less than standard SC-FDMA symbol lengths, by the resource of carrying information in each SC-FDMA symbol lengths after division Set identical with standard SC-FDMA symbols, surplus resources are used as the length as CP in the SC-FDMA symbols after dividing after division Degree（Less than the length 144*Ts of CP in standard SC-FDMA）.

If UL subframe are divided into using other time interval resources in extension CP, UL subframe2 in addition to t1 and t2 11 SC-FDMA symbols, each SC-FDMA symbol lengths after division are less than the SC-FDMA symbol lengths of standard.After dividing Each SC-FDMA symbol lengths in carrying information resource set it is identical with standard SC-FDMA symbols, surplus resources as stroke CP length in SC-FDMA symbols after point（Less than the length 512*Ts of CP in standard SC-FDMA）.

With UE2 similarly, UE1 also opens up t1 and t2 as the launch party of D2D information on UL subframe2.UL The dividing mode of other time interval resources in subframe2 in addition to t1 and t2 is similar with UE2's.
