Device and method for controlling interference

摘要

Embodiments herein relate to a method in a transceiver (400) for enabling control of interference cancelling in the transceiver (400). The transceiver (400) is in a first decoding mode. The transceiver (400) stores a received signal comprising a data block. The transceiver (400) decodes the received signal using the first decoding mode, thereby obtaining the data block. When an event is triggered, the transceiver (400) retrieves the stored signal. The transceiver (400) decodes the retrieved signal using a second decoding mode, thereby obtaining the data block. The transceiver (400) controls the interference cancelling in the transceiver (400), based on the data block decoded using the first decoding mode and the data block decoded using the second decoding mode.

1. A method in a transceiver for enabling control of interference cancelling in the transceiver, the transceiver being in a first decoding mode, the method comprising:
storing a received signal comprising a data block; decoding the received signal using the first decoding mode to obtain the data block, wherein the first decoding mode is a non-interference decoding mode; when an event is triggered, retrieving the stored signal, the event being associated with at least one of:
a block error rate,a number of corrected decoded signals,a code rate,a transport block size,a signal to interference and noise ratio,a change of a serving cell, anda location of the transceiver in a cell; decoding the retrieved stored signal using a second decoding mode to obtain the data block, wherein the second decoding mode is an interference decoding mode; controlling the interference cancelling in the transceiver, based on the data block decoded using the first decoding mode and the data block decoded using the second decoding mode; wherein the controlling the interference cancelling in the transceiver comprises determining whether the transceiver remains in the first decoding mode or changes to the second decoding mode.
