WIRELESS COMMUNICATION SYSTEM WITH SINGLE-SUBBAND USER EQUIPMENT

摘要

A radio network node (120) is configured to operate within a system bandwidth comprising multiple subbands and to serve a user equipment (110) limited to operating within only one subband during any given subframe. The radio network node (120) is configured to generate configuration information and to send that configuration information to the user equipment (110). In some embodiments, the configuration information indicates a location within the system bandwidth of a single subband within which the user equipment (110) is to be operated during a subframe. Alternatively or additionally, the configuration information indicates a mode according to which the user equipment (110) is to feed back channel state information to the radio network node (120). According to the indicated mode, in a subframe where CQI is reported, the user equipment (110) shall report one wideband CQI value which is calculated assuming transmission on the subband within which the user equipment (110) is configured to operate in that subframe.
