Abstract
Frequency offset compensating methods and apparatus are provided. A frequency offset of a terminal according to the pilots is estimated, and terminals are grouped according to the frequency offset of the terminals. The terminals in different frequency offset groups are dispatched and are scheduled to occupy the time frequency resources in different time slices. Frequency offset compensation is carried on for each group of terminals by using a corresponding frequency offset compensation value.
Claims20
A method for frequency offset compensation, comprising:
- estimating a frequency offset of a terminal according to the pilots in the uplink signals of the terminal;
- grouping terminals according to the frequency offset of each terminal by allocating the terminals that can use the same frequency offset compensation value for compensation into a same group;
- scheduling the terminals in different groups to enable the terminals in different groups to occupy time frequency resources in different time segments;
- and
- performing compensation for the frequency offset of the terminals in each group with frequency offset compensation value corresponding to each group.
