Latest Patents

Zhaohong Song holds 2 patents. His latest patents include:

1. **Method for obtaining channel state information, apparatus, and computer storage medium** - This patent relates to methods for obtaining channel state information (CSI). One example method includes allocating, by a network device to a terminal device according to a preset rule, a transmission resource for transmitting a sounding reference signal (SRS) in a cell to which the terminal device belongs. The transmission resources for transmitting SRSs in different cells do not overlap at all or partially overlap. The network device receives the SRS transmitted by the terminal device on the allocated transmission resource and performs channel quality estimation based on the received SRS to obtain CSI.

2. **Communications method and apparatus** - This patent describes methods and communication apparatus. In one example method, a base station divides a coverage area of a first antenna into at least two cells and performs weighted processing on data carried on time-frequency resources of the at least two cells to map the data carried on the time-frequency resources of the at least two cells to a channel of the first antenna. The base station combines the data carried on the time-frequency resources of the at least two cells and either transmits at least two directional beams using the first antenna or transmits one directional beam.
