Embodiment approach

[0160] As a first possible implementation manner of this embodiment, the precoding matrix information includes: matrix W 1 The first transmission precoding matrix TPMI and matrix W 2 The second TPMI.

[0161] Specifically, after the access network device selects the antenna port group set for the terminal device, the access network device performs channel estimation based on the reference signal corresponding to the antenna port group set, and obtains the channel estimation result H corresponding to the antenna port group set, and uses The H presets the first codebook from the access network equipment (the first codebook is about the matrix W 1 The codebook corresponding to the first TPMI) and the second codebook (the second codebook is about the matrix W 2 and the codebook corresponding to the second TPMI) respectively determine the matrix W 1 and matrix W 2 , for example, it can be that the access network equipment is based on the matrix W 1 and matrix W 2 As a result ...

Abstract

The application provides an information transmission method and information transmission equipment. The information transmission method comprises the steps that: access network equipment receives antenna port grouping information from terminal equipment, wherein the antenna port grouping information comprises information of at least one antenna port group of the terminal equipment and informationof at least one antenna port included in each antenna port group, or information of the at least one antenna port group of the terminal equipment and information of an antenna port of the terminal equipment; the access network equipment transmits indication information to the terminal equipment according to the antenna port grouping information, wherein the indication information is used for indicating an antenna port group set used by the terminal equipment to perform uplink information transmission at a first moment, the antenna port group set comprises at least one first antenna port group,and the first antenna port group is one of the antenna port groups indicated by the antenna port grouping information. The information transmission method provided by the invention avoids the terminal equipment from continuously transmitting uplink information on a sheltered antenna port, improves the uplink information transmission efficiency of the terminal equipment, and reduces the power consumption of the terminal equipment.

Description

technical field [0001] The present application relates to communication technologies, and in particular to an information transmission method and equipment. Background technique [0002] Massive Multiple Input Multiple Output (Massive MIMO for short) can further improve system capacity by utilizing more spatial degrees of freedom, and is one of the key technologies in the new generation of radio access technology (New Radio Access Technology, NR). Compared with the terminal equipment in LTE, the terminal equipment in NR is configured with more antennas. For example, compared with LTE uplink, it supports simultaneous transmission of up to 4 antennas, and uplink transmission in NR can support antenna ports for simultaneous transmission. The number may be 8, 16, or even 32. In addition, the number of receiving antennas that can be supported by the UE side will also increase accordingly. In this way, the joint processing of multiple receiving antennas can provide interference su...
