Method, apparatus, and system for sending data in hybrid networking

摘要

Embodiments of the present invention provide a method, an apparatus, and a system for sending data in hybrid networking. The method includes: determining an order quantity N of highest-order MIMO data and a quantity M of data types in the hybrid networking, where N is an even number not less than 2, and M is a natural number not less than 2; performing ith linear transformation processing on ith-type data among the M types of data, to obtain N pieces of ith-type output data having a same power, where i is a natural number less than or equal to M; and respectively outputting the N pieces of ith-type output data having a same power to N physical antennas, so that each physical antenna combines output data received by the physical antenna and then sends data obtained after the combining.

1. A method for sending data in hybrid networking, wherein the method comprises:
determining an order quantity N of highest-order multiple-input multiple-output (MIMO) data in hybrid networking and a quantity M of data types in the hybrid networking, wherein N is an even number not less than 2, and M is a natural number not less than 2; performing precoding processing on MIMO user data to obtain encoded MIMO user data, or performing precoding processing on the MIMO user data and third-type pilot information, to obtain the encoded MIMO user data; combining the encoded MIMO user data, second-type pilot information, and the third-type pilot information, to obtain the MIMO data, wherein the second-type pilot information is channel estimation pilot information used by a terminal to perform channel estimation, and the third-type pilot information is data demodulation pilot information used by the terminal to demodulate the MIMO user data; performing ith linear transformation processing on ith-type data among the M types of data, to obtain N pieces of ith-type output data having a same power and N pieces of MIMO output data having a same power, wherein i is a natural number less than or equal to M; and respectively outputting the N pieces of the ith-type output data having a same power to N physical antennas, so that each physical antenna combines output data received by the physical antenna and then sends data obtained after the combining.
