Communication method and apparatus

A communication method, comprising:

• sending M pieces of channel estimation information, wherein the M pieces of channel estimation information are used to determine a type of a target positioning manner, an mth piece of channel estimation information in the M pieces of channel estimation information is estimation information of a channel between an mth cell node in M cell nodes and a terminal device, M is a positive integer, and m is a positive integer ranging from 1 to M;
• obtaining second request information for requesting N pieces of channel estimation information, wherein the second request information comprises information indicating the type of the target positioning manner;
• and
• sending the N pieces of channel estimation information, wherein the N pieces of channel estimation information are used to position the terminal device, an nth piece of channel estimation information in the N pieces of channel estimation information is estimation information of a channel between an nth cell node in N cell nodes and the terminal device, the N cell nodes are included in the M cell nodes, N is a positive integer less than or equal to M, and n is a positive integer ranging from 1 to N.

A communication apparatus, comprising:

• a processor;
• and
• a non-transitory memory storing program instructions that, when executed by the processor, cause the communication apparatus to:
• obtain M pieces of channel estimation information, wherein an mth piece of channel estimation information in the M pieces of channel estimation information is estimation information of a channel between an mth cell node in M cell nodes and a terminal device, M is a positive integer, and m is a positive integer ranging from 1 to M;
• determine a type of a target positioning manner based on the M pieces of channel estimation information, and
• obtain N pieces of channel estimation information based on the type of the target positioning manner, wherein the N pieces of channel estimation information are used to position the terminal device, an nth piece of channel estimation information in the N pieces of channel estimation information is estimation information of a channel between an nth cell node in N cell nodes and the terminal device, the N cell nodes are comprised in the M cell nodes, N is a positive integer less than or equal to M, and n is a positive integer ranging from 1 to N.
