Abstract
A method includes, in a mobile communication terminal, receiving signals from a base station in a sequence of time frames. Based on the received signals, a classification of the time frames into first and second types is determined in the terminal, such that a level of interference in the time frames of the first type is lower than the level of interference in the time frames of the second type. The received signals are decoded based on the time frames and the corresponding classification.
Claims14
A method, comprising:
- in a mobile communication terminal, receiving signals from a base station in a sequence of time frames;
- based on the received signals, determining in the terminal a classification of the time frames into first and second types, such that a level of interference in the time frames of the first type is lower than the level of interference in the time frames of the second type;
- and
- tracking one or more of a gain, a frequency and a timing of the received signals based on the time frames of the first type and not on the time frames of the second type.

Apparatus, comprising:
- a receiver, which is configured to receive downlink signals from a base station in a sequence of time frames;
- and
- processing circuitry, which is configured to determine a classification of the time frames into first and second types based on the received signals, such that a level of interference in the time frames of the first type is lower than the level of interference in the time frames of the second type, and to track one or more of a gain, a frequency and a timing of the received signals based on the time frames of the first type and not on the time frames of the second type.
