Definitions
- the present invention relates to the field of communications, and in particular to a control information processing method and apparatus.
- a base station side for example, an evolved Node B, ie, an eNB
- spatial multiplexing may be adopted to increase the data transmission rate, that is, the same is used at the transmitting end.
- Time-frequency resources transmit different data at different antenna locations, and the receiving end (eg, user equipment UE) also uses multiple antennas to receive data. All the resources of all antennas are allocated to the same user in the case of a single user. The user occupies the physical resources allocated to the base station side in a single transmission interval. This transmission method is called single user multiple input and multiple output (Single User).
- the physical resource sharing mode may be a space division multiple access mode or a space division multiplexing mode.
- the transmission mode is called Multiple User Multiple-Input Multiple-Out-put (MU-MIMO).
- the physical resources allocated by the base station side refer to time-frequency resources. If the transmission system is to support both SU-MIMO and MU-MIMO, the eNB needs to provide the UE with data in these two modes.
- the eNB When the UE is in the SU-MIMO mode or the MU-MIMO mode, it is necessary to know the rank (Rank) used by the eNB to transmit MIMO data for the UE.
- SU-MIMO mode all antenna resources are allocated to the same user, and the number of layers used to transmit MIMO data is equal to the rank used by the eNB to transmit MIMO data.
- MU-MIMO mode the number of layers used for one user transmission Less than the total number of layers of MIMO data transmitted by the eNB, if SU-MIMO mode and MU-MIMO handover are to be performed, the eNB needs to notify the UE of different control data in different transmission modes.

- ⁇ ower -° ffset is used to indicate that the power of one user is halved (ie, -lOloglO (2)) in MU-MIMO mode, because MU-MIMO transmission mode 5 only supports two users.
- MU-MIMO transmission through this downlink power domain, MU-MIMO transmission mode 5 can support dynamic switching of SU-MIMO mode and MU-MIMO mode, but in the SU-MIMO mode or MU-MIMO mode, this DCI format pair A UE supports only one stream transmission.
- LTE Release 8 supports single-user transmission of up to two streams in transmission mode 4, since the switching between transmission modes can only be semi-static, it cannot be used in LTE version 8.
- a dual-stream beamforming (Beamforming) transmission mode is introduced, and downlink control information is added to DCI format 2B to support this transmission mode, and downlink control information is provided.

- NDI new data indication
- a dynamic handover transmission mode supporting single-use MIMO and multi-user MIMO is introduced, which supports at least 8 layers of transmission, and downlink control information adds DCI format 2C to support transmission mode, and downlink control information.
- the processing method and device have the joint coding identifier bits of the scrambling code identity, the antenna port and the layer number, the 8 antenna ports support at least 8 layers of single-user MIMO transmission, and the scrambling code identity supports multi-user MIMO transmission.
- a multi-point coordinated transmission COMP transmission mode is introduced.
- the COMP technology is mainly used to improve the throughput of the cell edge.
