Embodiment 1
[0129] In this embodiment, there are three types of beam attributes, and the number of transmission layers is 2. Multiple pieces of sub-information jointly indicate the transmission layer and the beam attributes among them as an example for illustration, that is, K=3, Layer=2, and Layer-x and beam jointly indicate.
[0130] As shown in Table 7, in this indication mode, an overhead of 3 bits is required.
[0131] Table 7
[0132]
[0133]
[0134] In this indication method, 000 is used to indicate that a certain beam corresponds to the beam attribute of the transmission layer 1 (Layer-1) is the beam attribute 1, and the beam attribute corresponding to the transmission layer 2 (Layer-2) is also the beam attribute 1, That is, the beam corresponds to both Layer-1 and Layer-2 and can be used as a reference beam, that is, a candidate reference beam. The candidate reference beam may be referred to as leading beam in this embodiment of the application, and may be referred to as...
Embodiment 2
[0142] In this embodiment, the beam attribute has three attributes, and the number of transmission layers is 2. The instruction information is used to indicate the attributes of the beams in each transmission layer as an example, that is, K=3, Layer=2, and each Layer uses multiple sub-information respectively. Instruct independently. As shown in Table 9, in this indication mode, an overhead of 2 bits is required to indicate that a certain beam corresponds to the three attributes of Layer-1, and an overhead of 2 bits is required for the three attributes corresponding to Layer-2, and a total of 4 bits of overhead are required.

[0144] sub information
[0145] In this indication mode, 1 bit is first used to indicate whether the indication information corresponds to Layer-1 or Layer-2. For example, 0 is used to indicate that the indication information indicates that a certain beam corresponds to the beam attribute of Layer-1. 1 indicates that the indic...
Embodiment 3
[0147] In this embodiment, the beam attribute has three attributes, the number of transmission layers is 2, and the instruction information is used to indicate the transmission layer and the beam attribute as an example, that is, K=3, Layer=2, and Layer-x and beam are classified to indicate the layer. Specifically, as shown in Table 10, use 00 to indicate that all beams corresponding to the two Layers (Layer-1 and Layer-2) are unlimited, that is, the beam attributes are all beam attribute 1: available and can be used as a leading beam; Use 01 to indicate no restrictions on Layer-1 and restrictions on Layer-2; use 10 to indicate no restrictions on Layer-2 and restrictions on Layer-1; use 11 to indicate all beams in Layer-1 and Layer-2 limit;
[0148] For a restricted Layer, there is no need to further indicate the beam attributes of a beam corresponding to the transport layer, that is, the beam attributes of all beams corresponding to the transport layer are attribute 3: non-ca...
