Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a system for receiving control information based on multipoint coordination.
Background
As the demand for communication increases, the transmission quality and throughput at the cell edge need to be improved. The coordinated multi-Point (CoMP) transmission technology utilizes the coordinated transmission of multiple cell transmitting antennas, and can effectively solve the problem of interference at the edge of a cell, thereby improving the capacity and reliability of a wireless link. In a system employing CoMP, a Cell that transmits downlink control information or receives uplink control information is called a Serving Cell (Serving Cell); the other cooperation points may be independent cells, which are referred to as cooperation cells, or may also be some dependent cells, which are generally referred to as cooperation points, and may be collectively referred to as cooperation cells for simplicity of description.
In the CoMP framework, during uplink transmission, a plurality of cooperating cells receive uplink data from the user. In the conventional joint processing method, each cell is simply and equivalently used as a receiving antenna, and received antenna data is directly transmitted to a serving cell for joint processing. The method does not fully utilize the processing capacity of each cooperative cell, occupies a large amount of bandwidth overhead of an interface between the service cell and the cooperative cell, and has higher requirements on the transmission bandwidth and the transmission delay of the interface. Aiming at the problem, the related technology provides a processing method based on CRC, namely, each cooperative cell carries out independent detection, demodulation and decoding to obtain a Check result of Cyclic Redundancy Check (CRC), then the CRC Check is selected to be correct in all cells to be used as a decoding result, and if the CRC Check of each cell is incorrect, soft bit data of a part of cells or equalized data are selected to carry out combined processing.
In the LTE-a system, control information may be multiplexed with service data and then jointly carried on the PUSCH for transmission. The control information carried to the PUSCH includes: channel Quality Indication (CQI), Rank Indication (RI), and/or acknowledgement/negative acknowledgement (ACK/NAK). In the current LTE-a protocol, the multiplexing rules of control information and service data are shown in fig. 1. Compared with the service data, the control information has the following characteristics: (1) the control information has small general data volume and does not occupy a large amount of interface bandwidth overhead; (2) some control information (e.g., RI, ACK/NAK, and CQI with a bit number less than 11) has no CRC check coding. Therefore, the above-described CRC-based processing method employed in the related art is no longer applicable to control information without CRC check coding. Moreover, with the above CRC-based processing method, each cell needs to perform independent detection, demodulation, and decoding, which inevitably results in performance loss, and for control information multiplexed with a large amount of service data, if the receiving antenna data of the cooperating cell is directly transmitted to the serving cell, a large amount of data overhead is incurred.
Aiming at the problem that in the related art, a large amount of data overhead is occupied by directly transmitting antenna data received by a cooperative cell to a serving cell, and performance loss is caused by adopting a CRC-based processing method, an effective solution is not provided at present.

Fig. 6 is a flowchart of a method for receiving control information based on coordinated multiple points according to an embodiment of the present invention, as shown in fig. 6, the method mainly includes the following steps:
step S602, one or more cooperative cells receive the multiplexing parameters of the control information and the service data in the physical uplink control channel (PUSCH) sent by the serving cell and received this time;
in a preferred implementation manner of the embodiment of the present invention, in order to enable each cooperative cell to correctly receive and demultiplex the control information and the service data, the serving cell may calculate a multiplexing parameter of the control information and the service data in the current PUSCH reception, and then transmit the multiplexing parameter as the configuration information to each cooperative cell. The configuration information transferred from the serving cell to the cooperating cell includes, but is not limited to: frequency domain resources occupied by the PUSCH, time domain resources occupied by the PUSCH (including subframes and SC-FDMA symbols), demodulation reference signal sequences or demodulation reference signal related configuration information, such as reference sequence group numbers, base sequence numbers, cyclic shift values, scrambling sequence initialization values, and information of source bit numbers, modulation symbol numbers, modulation modes and the like of each control information (and/or data) (including CQI and/or RI and/or ACK/NACK).
Step S604, when one or more cooperative cells receive the service data and the control information transmitted on the PUSCH after multiplexing, demultiplexing the received service data and the control information according to the multiplexing parameters;
in the embodiment of the present invention, the demultiplexing operation is a reverse process of channel interleaving and/or multiplexing of service data and control information in LTE-a, and in the embodiment of the present invention, the demultiplexing operation of the cooperating cell includes, but is not limited to, two manners shown in fig. 4 and fig. 5, that is, the PUSCH receiver of the cooperating cell may demultiplex the control information CQI, RI, and ACK/NACK at the stage of soft bit data or modulation symbols, respectively.
For example, assume the input to the de-channel interleaver is a modulation symbol, denoted as: h is0，h1，...，hR*HWherein, R is the number of subcarriers occupied by PUSCH in the configuration information transmitted by the serving cell, and H is the number of SC-FDMA symbols occupied by PUSCH recorded in the configuration information transmitted by the serving cell; it is assumed that the number of RI modulation symbols indicated in the configuration information is Q'RIAnd the number of ACK modulation symbols is Q'ACKQ 'represents the number of CQI modulation symbols'CQI. Then: the de-channel interleaving process comprises the following steps:
if so, extracting ACK modulation symbols
The process proceeds according to the following pseudo code:
if so, extracting RI modulation symbols
The process proceeds according to the following pseudo code;
wherein, ColumnSet of ACK and RI is defined as shown in Table5.2.2.8-1 (i.e. Table 1) and Table5.2.2.8-2 (i.e. Table 2) in LTE-ATS36.212 respectively:
table 1.
Table 2.
Suppose the input of the service data and control information multiplex is q0，q1，...，
Data and control information are demultiplexedThe process proceeds according to the following pseudo code:
alternatively, as shown in fig. 5, de-channel interleaving and/or traffic data and control information demultiplexing may be performed according to soft bits after demodulation, and the basic process is to first perform soft bit data per Qm(wherein, Q)mDivisor for modulation) soft bits, and then according to the above-mentioned processes of de-channel interleaving and service data and control information demultiplexing, according to the unit of packet.
Step S606, one or more cooperative cells transmit the demultiplexed control information to the serving cell.
If demultiplexing of the service data and the control information is performed at a modulation symbol stage, the cooperative cell transmits a modulation symbol of the control information obtained after demultiplexing to the serving cell, and if demultiplexing of the service data and the control information is performed on the soft bit data obtained after demodulation, the cooperative cell transmits the soft bit data of the control information obtained after demultiplexing to the serving cell.
In a preferred implementation manner of the embodiment of the present invention, the cooperative cell may further transfer a signal-to-noise ratio of the control information to the serving cell.
After the serving cell receives the soft bit data (or modulation symbols) and/or the snr (signal to noise ratio) transmitted by each cooperative cell, the soft bit data or the modulation symbols are combined.
For example, in the uplink joint receiving system shown in fig. 7, a Cell _1 is a serving Cell of a User Equipment (UE) UE _11, cells Cell _2, Cell _3, …, and Cell _ N is a cooperative Cell of the UE _1, the serving Cell and the cooperative Cell are connected through an X2 interface or other interfaces, and the cells Cell _2, Cell _3, …, and Cell _ N demultiplex multiplexed service data and control information carried on a PUSCH according to control information and multiplexing parameters of the service data in the PUSCH reception sent by the Cell _1, and then transmit the demultiplexed control information to the Cell _1 through an interface with the Cell _ 1.
From the above description, it can be seen that the present invention achieves the following technical effects: the cooperative cell demultiplexes the received antenna data, and transmits control information obtained by demultiplexing to the serving cell, so that the interaction amount of data between the serving cell and the cooperative cell is reduced, performance loss caused by independent detection, demodulation and decoding of each cell is avoided, and the demodulation and decoding performance of the control information is improved.
