Wireless Communication System With Single-Subband User Equipment

摘要

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

1. A method implemented by a radio network node configured to operate within a system bandwidth comprising multiple subbands and to serve a user equipment limited to operating within only one subband during any given subframe, the method comprising:
generating configuration information that indicates a mode according to which the user equipment is to feed back channel state information to the radio network node, wherein according to the indicated mode, in a subframe where channel quality information (CQI) is reported, the user equipment shall report one wideband value which is calculated assuming transmission on the subband within which the user equipment is configured to operate in that subframe; and configuring the user equipment to feed back channel state information according to the indicated mode by transmitting the configuration information to the user equipment.
