MACRO DIVERSITY USING LIKELIHOOD VALUES

摘要

Method and arrangement in a serving base station for determining a binary value of information data received from a user equipment, by using a supportive likelihood value received from a supporting base station. The user equipment transmits information data to be received both by the serving base station and the supporting base station base station. The method comprises: decoding information data bits received from the user equipment into a first likelihood value, without determining a binary value for each bit of the information data, a supportive likelihood value of the information data bits transmitted from the user equipment is received from the supporting base station, which supportive likelihood value is based on a decoding of the information data bits performed in the supporting base station. The first likelihood value of the decoded information bits is combined with the received supportive likelihood value of the decoded information bits. Thus a binary value for each bit of the information data transmitted from the user equipment is determined, based on the combined first and supportive likelihood values.
