Embodiment 1
In the present embodiment, remote user C-RNTI and Downlink Control Information are handed down to nearly user by base station, closely
User first solves remote subscriber control information, then using interference cancellation techniques, obtains the nearly user PDSCH of oneself
Information.Fig. 1 is refer to, processing procedure comprises the steps.
Base station side:
The nearly user and remote user for being overlapped encoding is determined according to dispatching algorithm, determines that criterion includes:Wave beam
Shaping is identical with precoding direction, can also increase condition:Make the metric of debugging algorithm maximum.
The notice signaling for carrying remote user C-RNTI is sent to nearly user, and notice signaling can be RRC letter
(referring to embodiment 2) is made, can also be RRC signaling+DCI (referring to embodiment 3);
Downlink Control Information DCI is sent, the data dispatch in the DCI of each user including at least this user is believed
Breath, the power ratio information (referring to embodiment 4) in the DCI of this user also comprising remote user and nearly user.
UE side:
Receive the notice signaling for carrying remote user C-RNTI;
Using the remote user C-RTNI and C-RNTI blind check PDCCH of this UE, include in acquisition DCI
Data scheduling information;
Using remote user C-RNTI data schedule information, remote user data is received, receive in signal from total
Remote user data is removed, obtains this user data.
Example 2:Remote user C-RNTI is issued and is received by RRC signaling
UE, eNB in connected state is determined by its channel condition information can be using supercomposed coding pairing
Remote user, the criterion of judgement is:Beam forming/precoding direction is identical, and makes the metric of debugging algorithm
(as total downstream rate) maximum user is as the remote user of this UE;
UE connects reallocation message by RRC and obtains the remote user C-RNTI that base station issues, i.e., connect in RRC
Connecing in reallocation message increases remote user C-RNTI field, and length is 16bit;
After UE obtains remote user C-RNTI, can be used to solve remote user data, so as to receive signal from total
Middle remove the interference of remote user data, obtain the descending PDSCH of this UE.
Embodiment 3:Base station connects reallocation message by RRC and notifies one group remote user C-RNTI information list
To nearly user, the DCI dynamic for then being carried by PDCCH issues the remote user C-RNTI of current superposition
Index.Specifically include:
UE, eNB in connected state is determined some to join using supercomposed coding by its channel condition information
To remote user's group;The criterion of judgement is:Beam forming/precoding direction identical user is selected as this
Remote user's candidate set of UE.
UE connects the C-RNTI list that reallocation message obtains remote user's candidate set by RRC, i.e., in RRC
Increase by one group remote user C-RNTI list in connection reallocation message, the length of each C-RNTI is 16bit.
After UE obtains remote user C-RNTI list, each downlink data dispatching eNB can all pass through
PDCCH therefrom indicates one or more remote user C-RNTI indexes for being overlapped coding with the UE,
UE obtains the C-RNTI of remote user from list according to index;UE can be with the remote user of the C-RNTI blind check
Downlink Control Information so that demodulate remote user data, after interference elimination treatment, finally give this
The descending PDSCH of UE.
Example 4:The form of power ratio field can be any one following.
The ratio of nearly user and remote user power
When being represented with 1bit
Index | The ratio of nearly user and remote user power |
0 | 1/9 |
1 | 3/17 |
When being represented with 2bit
Index | The ratio of nearly user and remote user power |
0 | 1/19 |
1 | 1/9 |
2 | 3/17 |
3 | 1/4 |
Nearly user accounts for the ratio of general power
When being represented with 1bit
Index | Nearly user accounts for the ratio of general power |
0 | 1/10 |
1 | 3/20 |
When being represented with 2bit
Index | Nearly user accounts for the ratio of general power |
0 | 1/20 |
1 | 1/10 |
2 | 3/20 |
3 | 1/5 |
Can also be:Remote user accounts for the ratio of general power.
