Abstract
Various methods and devices are provided to address the need for improved multicarrier system operation. In one method, an indication of a received signal power level at a UE (user equipment) is received (501) from the UE. A carrier is then selected (502) on which to schedule the UE. The carrier is selected from a group of carriers based on the indication of the received signal power level at the UE.
Claims13
A method for carrier selection, the method comprising:
- receiving, by a base station, from user equipment (UE) an indication of a received signal power level at the UE;
- selecting, by the base station, a carrier, from a plurality of carriers, on which to schedule the UE based on the indication of the received signal power level at the UE;
- and
- scheduling, by the base station, the UE on the carrier selected, wherein,
- the plurality of carriers comprises a lower-frequency carrier and a higher-frequency carrier, and
- the selecting a carrier on which to schedule the UE includes selecting the lower-frequency carrier when the indication of the received signal power level indicates that the received signal power level is below a first threshold level.

A network node of a communication system, the network node being configured to communicate with other devices in the system, wherein the network node is operative
- to receive from user equipment (UE) an indication of a received signal power level at the UE;
- to select a carrier, from a plurality of carriers, on which to schedule the UE based on the indication of the received signal power level at the UE;
- and
- to schedule the UE on the carrier selected, wherein,
- the plurality of carriers comprises a lower-frequency carrier and a higher-frequency carrier, and
- being operative to select the carrier on which to schedule the UE includes being operative to select the lower-frequency carrier when the indication of the received signal power level indicates that the received signal power level is below a first threshold level.
