Methods and devices for reporting a downlink channel quality

摘要

The invention relates to a method (90) in a user equipment (4) for reporting a downlink channel quality in a communication system (1) comprising a first radio access technology system (2) and a second radio access technology system (3). The user equipment (4) is in connection with a primary serving cell on the first radio access technology system (2) and with a secondary serving cell on the second radio access technology system (3). The method (90) comprises: determining (110) channel quality for the second radio access technology system (3) using an indicator format of the radio access technology of the second radio access technology system (3); mapping (120) an indicator of the channel quality having the indicator format of the second radio access technology to an indicator format used for channel quality indicators in the first radio access technology system (2); and transmitting (130) the indicator of the channel quality for the second radio access technology system (3) to the communication system (1) using the indicator format of the first radio access technology on an uplink carrier of the first radio access technology system (2). The invention also relates to a user equipment, methods in a network node and a network node.

1. A method, in a user equipment, for reporting a downlink channel quality in a communication system, the communication system comprising a first radio access technology system and a second radio access technology system, the user equipment being in connection with both a primary serving cell of the first radio access technology system and a secondary serving cell of the second radio access technology system, the method comprising:
determining a channel quality for the second radio access technology system; mapping the channel quality to an indicator index of the channel quality having an indicator format used for channel quality indicators of the second radio access technology system; mapping the indicator index of the channel quality having the indicator format of the second radio access technology system to an indicator format used for channel quality indicators of the first radio access technology system; and transmitting, to the primary serving cell of the first radio access technology system on an uplink carrier, the indicator index of the channel quality for the second radio access technology system of the communication system using the indicator format of the first radio access technology system.
