In the following, SOMA pairing state is divided to be illustrated scene and SOMA the pairing state of the non-explicit instruction of edge UE to the scene of edge UE explicit instruction.

In scene of the SOMA pairing state to the non-explicit instruction of edge UE, eNB only sends SOMA to center UE and matches status indication information.In this way, the UE for receiving SOMA pairing status indication information can determine that it is center UE.That is, the SOMA pairing state for receiving the UE of SOMA pairing status indication information includes that channel condition locating for the UE is good compared with the UE matched with the UE.

It carries out demodulating required parameter including the high-order modulation constellation figure instruction information that the eNB is used for the UE in SOMA pairing state, the high-order modulation constellation figure instruction information is used for the high order modulation order used needed for UE instruction demodulation.

Here high-order modulation constellation figure is based on corresponding planisphere after multiple UE information superpositions coding, such as, the low-order information of demodulating information corresponding constellation point needed for the UE of center, and the high-order information of demodulating information corresponding constellation point needed for edge UE, high-order modulation constellation figure used in the eNB that Downlink Control Information is included in the present embodiment indicates information, high order modulation order needed for being used to indicate center UE demodulation, center UE can obtain demodulating information required for the UE of center from the corresponding low-order information of high order modulation order.

Further, for center UE, in Downlink Control Information other than the high-order modulation constellation figure used comprising eNB indicates information, can also include following information at least one of or it is multinomial: SOMA match power allocation information, pairing interference instruction information, with, exist pairing UE interference resource allocation information.

Wherein, SOMA pairing power allocation information is used to indicate the power allocation information of the pairing UE of the UE and/or UE, such as: resource unit (resource element, RE the power sharing ratio between the pairing UE of transmission general power and the UE and the UE), or, the power of the transmission general power of RE and the UE, or, the power of the pairing UE of the transmission general power and UE of RE, or, the power of the pairing UE of the power of the UE and the UE.It should be noted that, existing power indicative information only indicates the transmission general power of RE, and in the present embodiment, if UE has pairing UE under SOMA state, the distribution information (direct or indirect) that can then tell the UE power, enables the UE to obtain the data transmission power of itself, specifically how to enable UE obtain itself data transmission power can for it is above-mentioned citing one of, it may be other modes, not limit herein.

Wherein, pairing interference instruction information can directly indicate that UE is interfered with the presence or absence of pairing UE, such as can be with 1 bit explicit instruction with the presence or absence of pairing UE interference.

Wherein, the resource allocation information is used to indicate running time-frequency resource used in the pairing UE of the UE, as there is running time-frequency resource two kinds of situations identical with running time-frequency resource used in the UE of center and not exactly the same used in pairing UE, if matching running time-frequency resource used in UE and running time-frequency resource used in the UE of center being not exactly the same, center UE can be made to know which portion of time frequency resources in the presence of pairing UE interference be by the resource allocation information.

It is configured in the Downlink Control Information that receives of center UE of SOMA pairing state that DCI_TM (downlink control inforamtion_transmission mode) can also be may be simply referred to as comprising some necessary control information corresponding with downlink transfer mode in the prior art.

Specifically, the necessary control information for example can be the information such as order of modulation or resource allocation, wherein resource may include time-domain resource distribution information or frequency domain resource distribution information etc., and order of modulation is UE required when being demodulated after receiving the data；Wherein, order of modulation may include existing low-order-modulated order.

Optionally, for edge UE, the reception of DCI and the demodulation of data can be carried out according to existing mode, it will not be described here.

In scene of the SOMA pairing state to edge UE explicit instruction, SOMA pairing status indication information had both issued center UE, also issued edge UE.It can be center UE or edge UE by matching the different assignment differentiation of status indication information to SOMA.For example, it is 0 that the SOMA pairing status indication information of center UE, which is matched, in the case where two UE pairings, it is 1 that the SOMA pairing status indication information of edge UE, which is matched,.In this way, the UE for receiving SOMA pairing status indication information can match status indication information by SOMA and determine that it is center UE or edge UE.For edge UE, the SOMA pairing state of the edge UE of the SOMA pairing status indication information received includes that channel condition locating for the UE is poor compared with the UE matched with the UE.

In this scenario, information included in the Downlink Control Information that receives of center UE of SOMA pairing state and above-mentioned SOMA are configured to and matches state to identical in the scene of the non-explicit instruction of edge UE, details are not described herein.It is configured in Downlink Control Information received by the center UE and edge UE of SOMA pairing state, also may include some necessary DCI_TM corresponding with downlink transfer mode in the prior art, also it will not go into details herein.

ENB is sent to included in the Downlink Control Information of edge UE and carries out demodulating required parameter including SOMA pairing power allocation information for edge UE.SOMA pairing power allocation information is used to indicate the power allocation information of the pairing UE of the UE and/or UE, such as: the transmission of RE Power sharing ratio between general power and the pairing UE of the UE and the UE, or, the transmission general power of RE and the power of the UE, or, the power of the pairing UE of the transmission general power and UE of RE, or, the power of the pairing UE of the power of the UE and the UE, so that edge UE can obtain the power of itself received data.Specifically edge UE how to be enable to obtain the power of itself received data, can be one of citing above-mentioned, or other modes, the present embodiment are not specifically limited in this embodiment.

It should be noted that, the Downlink Control Information of the UE of SOMA pairing state is configured to due to being sent to, with be sent to be not configured as SOMA pairing state UE Downlink Control Information it is not exactly the same, therefore, in the present embodiment, the format of Downlink Control Information can be distinguished simply, i.e., Downlink Control Information under non-SOMA pairing state under certain transmission mode is defined as DCI_TM_UE, that is, descending control information format in the prior art, and the Downlink Control Information under the SOMA pairing state under certain transmission mode is defined as DCI_TM_UE_SOMA；In actual application, all same category informations that DCI_TM_UE is included be may include in DCI_TM_UE_SOMA.In this way, UE can receive DCI according to the format of DCI_TM_UE_SOMA with SOMA status indication information based on the received.

This gives the schemes that network side can only send SOMA status indication information to center UE；The scheme of SOMA status indication information can all be sent to the UE of two pairings by also giving network side.Using the scheme of the present embodiment, the UE in SOMA pairing state can realize that information is transmitted using identical running time-frequency resource.Further, since the SOMA status indication information is sent by high-level signaling, it is lower to send frequency, comprising in SOMA pairing state UE demodulate needed for parameter Downlink Control Information can not each TTI issue, therefore Downlink Control Information is issued compared to each TTI save signaling overheads, in addition, the power distribution and resource allocation of UE in SOMA pairing state is more flexible, and base station is realized using the power resource on identical running time-frequency resource and same unit running time-frequency resource to the information of at least two UE and is transmitted.

Fig. 3 is the flow chart of control information indicating method provided by Embodiment 2 of the present invention.As shown in figure 3, control information indicating method provided in this embodiment can specifically be executed by the UE for being configured to SOMA pairing state.This method may include:

S201, UE receive the SOMA status indication information that eNB is sent；The SOMA status indication information is used to indicate the SOMA pairing state of the UE, received Downlink Control Information needed for determining the UE.

Optionally, eNB can trigger the movement that SOMA status indication information is sent to UE according to actual needs.Such as, the biggish UE of channel condition difference is allowed to be matched.Optionally, when eNB can be according to existing channel measurement algorithm, when judging larger there are channel condition difference locating for two UE in covered cell, eNB triggers the movement that SOMA status indication information is sent to UE, this the two locating biggish UE of channel condition difference are matched, so that two UE is can use identical running time-frequency resource and realizes information transmission.For downlink, the UE in SOMA pairing state shares a unit running time-frequency resource, and the down transmitting power resource being shared on the unit running time-frequency resource on unit running time-frequency resource.Unit running time-frequency resource can be a subcarrier and OFDM symbol；UE in SOMA pairing state shares identical down transmitting power resource with the pairing UE of UE on unit running time-frequency resource, refers to that down transmitting power the sum of of two UE in SOMA pairing state on unit running time-frequency resource is constant.

It should be noted that the transmission mode for being allocated to different UE can be the same or different, the present embodiment is not limited this.

Specifically, the SOMA status indication information that UE is received is eNB by high-level signaling, as RRC signaling is sent, it is lower to send frequency.

Wherein, UE can be the preferable UE of channel condition, or the poor UE of channel condition.

The SOMA for the UE that S202, the UE are indicated according to the SOMA status indication information matches state, receives the Downlink Control Information that the eNB is sent, carries out demodulating required parameter comprising the UE for being in SOMA pairing state in the Downlink Control Information.

The Downlink Control Information can be to be issued by PDCCH.

In this step, received Downlink Control Information needed for the UE can be determined according to the SOMA status indication information receives the Downlink Control Information that the base station is sent according to required received Downlink Control Information；Wherein, received Downlink Control Information needed for determining includes at least one of the following or a variety of: the format of received Downlink Control Information needed for determining, the type of received Downlink Control Information needed for determining, and, the title of the received parameter for demodulation needed for determining.

Optionally, before the SOMA status indication information that the UE receives that eNB is sent, transmission mode configuration information Cofig_TM_UE can also be received, to configure transmission mode used in UE；Wherein, the Cofig_TM_UE of different UE configuration can be different, can also be identical, and the present embodiment is not limited this.

Specifically, transmission mode may include one of classification, open loop multiplexing, closed loop multiplexing and spatial reuse or a variety of, since the Downlink Control Information transmitted in channel is related with transmission mode, can lead to Transmission mode used in transmission mode configuration information configuration UE is crossed, in order to which UE is according to the transmission mode configured, received Downlink Control Information needed for determining, for example, the format of received Downlink Control Information needed for determining.To which UE searches for the format of the required received Downlink Control Information in the format of multiple Downlink Control Information.

UE is in the transmission mode for knowing configuration according to transmission mode configuration information, and know that being configured as SOMA matches state according to SOMA status indication information is received, so that it is determined that needing received Downlink Control Information, and then realize the reception of required received Downlink Control Information.

It should be noted that above-mentioned UE can be center UE, it is also possible to edge UE.

For SOMA pairing state to the scene of the non-explicit instruction of edge UE, only center UE can receive SOMA status indication information Cofig_SOMA.

Under the scene, it carries out demodulating required parameter including the high-order modulation constellation figure instruction information that the eNB is used for the UE in SOMA pairing state, the high-order modulation constellation figure instruction information is used for the high order modulation order used needed for UE instruction demodulation.

Further, in the Downlink Control Information that center UE is received can also include following information at least one of or it is multinomial: SOMA match power allocation information, pairing interference instruction information, and exist pairing UE interference resource allocation information.

Wherein, SOMA pairing power allocation information is used to indicate the power allocation information of the pairing UE of the UE and/or UE, such as: the power sharing ratio between the transmission general power of RE and the pairing UE of the UE and the UE, or, the transmission general power of RE and the power of the UE, or, the power of the pairing UE of the transmission general power of RE and the UE, or, the power of the pairing UE of the power of the UE and the UE.It should be noted that, existing power indicative information only indicates the transmission general power of RE, and in the present embodiment, if UE has pairing UE under SOMA state, it can then tell the distribution information (direct or indirect) of the UE power, enable the UE to obtain the data transmission power of itself, specifically how to enable UE obtain itself data transmission power can for it is above-mentioned citing one of It may be other modes, not limit herein.

Being configured to can also be comprising some necessary DCI_TM corresponding with downlink transfer mode in the prior art in the Downlink Control Information that receives of center UE of SOMA pairing state.

Specifically, the necessary control information for example can be the information such as order of modulation or resource allocation, wherein resource may include time-domain resource distribution information, and frequency domain resource distributes information etc., and order of modulation is UE required when being demodulated after receiving the data；Wherein, order of modulation may include existing low-order-modulated order.

Optionally, for edge UE, the reception of DCI and the demodulation of data can be carried out according to existing mode.

It should be noted that, due to when network side user is more, in order to save signaling overheads, network side is changed slower by the SOMA status indication information that high-level signaling configures, and actual UE pairing state change is very fast, such as in practical applications, eNB sends indicated center UE and edge UE in SOMA status indication information to UE and matches, i.e., center UE and edge UE share identical transmission power, however in actual dynamic process, when receiving the SOMA status indication information there may be center UE, it has been transmitted with the data of the edge UE of center UE pairing, at this time SOMA pairing state and the eNB of center UE it is practical issue it is not identical when SOMA status indication information.

Therefore, before the center UE indicates that information is demodulated according to the high-order modulation constellation figure, information can also be indicated according to high-order modulation constellation figure included in the Downlink Control Information, SOMA matches power allocation information, and pairing interferes instruction information and there is at least one in the resource allocation information of pairing UE interference or the multinomial determining interference that there is pairing UE.

Specifically, if described determine that the interference that there is pairing UE includes: the value that the value of the high-order modulation constellation figure instruction information is greater than the received low-order-modulated planisphere instruction information of the UE according to high-order modulation constellation figure instruction information included in the Downlink Control Information, there is pairing UE interference；And/or If the value of the high-order modulation constellation figure instruction information is equal to the value of the received low-order-modulated planisphere instruction information of the UE, there is no pairing UE interference.

Specifically, if described determine that the interference that there is pairing UE includes: that the UE matches power allocation information according to the SOMA and determines that the power assignment value of pairing UE is not 0 according to SOMA pairing power allocation information included in the Downlink Control Information, there is pairing UE and interfere.

For SOMA pairing state to the scene of edge UE explicit instruction, center UE and edge UE in SOMA pairing state can receive Cofig_SOMA.

Under the scene, UE can determine it itself is center UE or edge UE according to the value of the Cofig_SOMA received；For example, if Cofig_SOMA=0, then it represents that the UE is center UE, if Cofig_SOMA=1, then it represents that the UE is edge UE, and the present embodiment is not limited this.

In practical application, for center UE, information included in Downlink Control Information received by the UE of the center is with above-mentioned SOMA pairing state to identical in the scene of the non-explicit instruction of edge UE, and, it is configured in Downlink Control Information received by the center UE and edge UE of SOMA pairing state, can also be comprising some necessary DCI_TM corresponding with downlink transfer mode in the prior art, details are not described herein.

For edge UE, the Downlink Control Information that edge UE is received may include SOMA pairing power allocation information；UE is after receiving the Downlink Control Information that the eNB is sent by PDCCH, transmission power needed for can determining self transmission data based on transmission general power and SOMA pairing power allocation information (direct or indirect).

It is understood that knowing that the UE is center UE, then the center UE indicates that information is demodulated according to the high-order modulation constellation figure if the UE determines that locating channel condition is good compared with the UE matched with the UE according to the SOMA status indication information；If the UE determines that locating channel condition is poor compared with the UE matched with the UE according to the SOMA status indication information, know that the UE is edge UE, then the edge UE can match power allocation information according to the SOMA and be demodulated.

The technical solution of the present embodiment, after being configured to SOMA state due to UE, Downlink Control Information is different compared to the Downlink Control Information under non-SOMA state, and therefore, UE needs to receive new Downlink Control Information.Furthermore, under SOMA state, actual UE pairing situation may be dynamic, for SOMA state to the scene of the non-explicit instruction of edge UE, center UE needs to determine whether there is pairing UE interference according to Downlink Control Information, if there is no pairing UE interference, UE can directly retract into non-SOMA pairing state and be demodulated；For SOMA state to the field of edge UE explicit instruction Scape, center UE determines whether there is pairing UE interference according to Downlink Control Information, so that it is determined that there is the corresponding down transmitting power of center UE and demodulation mode in the resource of pairing UE, and edge UE only needs to match the down transmitting power that power allocation information determines data by SOMA, demodulates to be realized according to transmission power.The power distribution and resource allocation of UE in SOMA pairing state is more flexible, realizes the control information instruction of SOMA.
