User Equipment, Network Node and Methods Therein

摘要

A network node for demodulating uplink transmissions from a user equipment in a multiple cell communications network can be configured to receive uplink transmissions from the user equipment over a plurality of aggregated cells. The network node transmits, to the user equipment, determined timing advance information for uplink of one or more aggregated cells out of the plurality of aggregated cells. The network node receives, from the user equipment, an uplink transmission of at least one aggregated cell out of the plurality of aggregated cells. The network node then demodulates the received uplink transmission using weighted soft values in periods in the received uplink transmission. The periods are based on the transmitted timing advance information.

1. A method, in a network node, for demodulating uplink transmissions from a user equipment in a multiple cell communications network, the network node configured to receive uplink transmissions from the user equipment over a plurality of aggregated cells, the method comprising:
transmitting, to the user equipment, determined timing advance information for uplink of one or more aggregated cells out of the plurality of aggregated cells; receiving, from the user equipment, an uplink transmission of at least one aggregated cell out of the plurality of aggregated cells; and demodulating the received uplink transmission using weighted soft values in periods in the received uplink transmission, the periods based on the transmitted timing advance information.
