Self-interference handling in a wireless communication terminal supporting carrier aggregation

摘要

A wireless communication terminal that has the self-interference due to the support of carrier aggregation, aggregating and jointly using two or more component carriers for transmission and reception, performs a first set of measurements on a received signal on a first operating frequency, wherein the first set of measurements are performed during which the wireless terminal transmits or receives signals on a second operating frequency. In an alternative embodiment, the wireless communication terminal changes the maximum transmit power limit on a first operating frequency on a per-slot basis to reduce the impact of harmonic or intermodulation distortion on a received signal at a second operating frequency.

主权项

1. A method in a wireless communication terminal communicating over at least a first downlink channel and at least an uplink channel, the method comprising:
determining, by one or more processors based on a downlink signal, whether an uplink signal is scheduled for transmission on the uplink channel in a subframe, wherein the uplink signal spans at least two timeslots in the subframe and the uplink signal comprises a first set of resource blocks in a first timeslot and a second set of resource blocks, different from the first set of resource blocks, in a second time slot; determining, by the one or more processors, a first value for power reduction for transmission of the uplink signal in the first timeslot; determining, by the one or more processors, a second value for power reduction for transmission of the uplink signal in the second timeslot; and transmitting the uplink signal in the subframe comprising at least the first timeslot and the second timeslot based on the first value for power reduction and the second value for power reduction.
