Abstract

A codebook configuration method, a port configuration method and a device for the same are provided. A communication device determines configuration information of a codebook, where the configuration information of the codebook includes at least one of value range selection information of a base vector in a construction model of the codebook or value range selection information of a codeword in the codebook. The communication device sends the configuration information of the codebook to a communication peer end.

Claims

1. A codebook configuration method, comprising:

determining, by a communication device, configuration information of a codebook, wherein the configuration information of the codebook comprises at least one of value range selection information of a base vector in a construction model of the codebook or value range selection information of a codeword in the codebook; and

sending, by the communication device, the configuration information of the codebook to a communication peer end.

2. The method of claim 1, wherein the configuration information of the codebook comprises at least one of configuration information of a codebook generation parameter or configuration information of a codebook subset restriction parameter.

3. The method of claim 1, wherein determining, by a communication device, configuration information of a codebook comprises:

configuring, by the communication device, the value range selection information of the base vector or the value range selection information of the codeword in at least one of following manners;

configuring the value range selection information of the base vector or the value range selection information of the codeword for various rank groups or layer groups, respectively;

configuring the value range selection information of the base vector or the value range selection information of the codeword for various feedback manners, respectively;

configuring the value range selection information of the base vector or the value range selection information of the codeword for various antenna groups, respectively;

or

configuring the value range selection information of the base vector or the value range selection information of the codeword for various measurement reference signal sets, respectively;

wherein the value range selection information of the base vector comprises value range selection information configured for a plurality of sub-ranges.

4. The method of claim 1, wherein the value range selection information of the base vector comprises value range information of part or all of base vector parameters related to the base vector, wherein the value range information comprises at least one of:

a starting position;

an ending position;

a number of values;

or

a selection rule.

5. The method of claim 1,

wherein the value range selection information of the base vector is configured in a manner of a bitmap, wherein each bit in the bitmap corresponds to a base vector group, and the base vector group comprises at least one base vector;

and

wherein a first state of each bit in the bitmap represents that the base vector group corresponding to the bit is selected, a second state represents that the base vector group corresponding to the bit is not selected, and any two adjacent bits in the first state are spaced apart by a same number of bits in the second state.

6. The method of claim 1, wherein a value range determined by the value range selection information of the base vector comprises at least one sub-range, and a difference between any adjacent values is equal in all sub-ranges.

7. The method of claim 1, wherein the value range selection information of the codeword is represented by value range information of a codeword index, and the value range information of the codeword index comprises at least one of following information of the codeword index:

a starting position;

an ending position;

a number of values;

or

a selection rule.

8. The method of claim 1,

wherein the value range selection information of the codeword is configured in a manner of a bitmap, wherein each bit in the bitmap corresponds to a codeword group or a codeword index value group, the codeword group comprises at least one codeword, and the codeword index value group comprises at least one codeword index value;

and

wherein a first state of each bit in the bitmap represents that the codeword group or the codeword index value group corresponding to the bit is selected, a second state represents that the codeword group or the codeword index value group corresponding to the bit is not selected, and any two adjacent bits in the first state are spaced apart by a same number of bits in the second state.

9. A codebook configuration device, comprising a processor and a storage device for storing computer executable instructions that when executed by the processor cause the processor to implement the method of claim 1 by:

determining configuration information of a codebook, wherein the configuration information of the codebook comprises at least one of value range selection information of a base vector in a construction model of the codebook or value range selection information of a codeword in the codebook; and

sending the configuration information of the codebook to a communication peer end.

10-15. -15. (canceled)

16. A port configuration method, comprising:

determining, by a communication device, port configuration information, wherein the port configuration information comprises selection information of port groups, each of the port groups comprises at least one port, and when a number of selected port groups is greater than 1, the port groups are selected in an equally spaced manner; and

sending, by the communication device, the port configuration information to a communication peer end.

17. The method of claim 16, wherein determining, by a communication device, port configuration information comprises:

configuring, by the communication device, the selection information of the port groups in at least one of following manners;

configuring the selection information of the port group for various rank groups or layer groups, respectively;

configuring the selection information of the port group for various feedback manners, respectively;
