Abstract
The present disclosure relates to a user equipment (200) for a wireless communication system. The user equipment comprises a transmitter (210) configured to generate a transmit signal (220), a transmitter feedback receiver (230) coupled to the transmitter and configured to measure a power of the transmit signal in a first mode of operation, and control circuitry (240) configured to select a second mode of operation of the transmitter feedback receiver, in which the transmitter feedback receiver (230) is configured to measure one or more neighboring inter-frequency or inter-RAT base stations.
Claims22
User equipment for a wireless communication system, comprising:
- a transmitter configured to generate a transmit signal;
- a transmitter feedback receiver;
- a main receiver;
- and
- control circuitry configured to:
- couple the transmitter feedback receiver to the transmitter for a first mode of operation and decouple the transmitter feedback receiver from the transmitter for a second mode of operation;
- measure a power of the transmit signal by using the transmitter feedback receiver operating in the first mode of operation;
- and
- measure one or more neighboring inter-frequency or inter-RAT base stations by selecting, based on an indication of whether previous signal quality measurements of neighboring inter-frequency or inter-RAT base stations exceed a predefined threshold, and using at least one of:
- the transmitter feedback receiver operating in the second mode of operation;
- or
- the main receiver.
Method for measuring one or more neighboring inter-frequency or inter-RAT base stations with a user equipment of a wireless communication system, the user equipment comprising a transmitter configured to generate a transmit signal, the method comprising:
- measuring a power of the transmit signal by using a transmitter feedback receiver coupled to the transmitter for measuring a power of the transmit signal;
- and
- measuring the one or more neighboring inter-frequency or inter-RAT base stations by selecting, responsive to an indication of whether previous signal quality measurements of neighboring inter-frequency or inter-RAT base stations exceed a predefined threshold, and using at least one of:
- the transmitter feedback receiver decoupled from the transmitter for measuring the one or more neighboring inter-frequency or inter-RAT base stations;
- or
- a main receiver different from the transmitter feedback receiver.
A computer program product comprising a non-transitory computer readable medium having computer readable program code embodied therein, wherein the computer readable program code, when being loaded on a computer, a processor, or a programmable hardware component, is configured to implement a method for measuring one or more neighboring inter-frequency or inter-RAT base stations with a user equipment of a wireless communication system, the user equipment comprising a transmitter configured to generate a transmit signal, the method comprising:
- determining a power of the transmit signal using a transmitter feedback receiver coupled to the transmitter for determining the power of the transmit signal;
- and
- measuring the one or more neighboring inter-frequency or inter-RAT base stations by selecting, responsive to an indication of whether previous signal quality measurements of neighboring inter-frequency or inter-RAT base stations exceed a predefined threshold, and using one of:
- the transmitter feedback receiver decoupled from the transmitter for measuring the one or more neighboring inter-frequency or inter-RAT base stations;
- or
- a main receiver different from the transmitter feedback receiver.
