Abstract
A method and apparatus for allocating resources to a low cost user equipment (UE) in a wireless communication system is provided. A base station (BS) allocates at least one sub-bandwidth among a system bandwidth to a low cost UE, and transmits information on the allocated at least one sub-bandwidth to the low cost UE. The at least one sub-bandwidth may include a set of resource physical resource blocks (PRBs) that the low cost UE can access at a given subframe.
Claims20
A method performed by a base station (BS) in a wireless communication system, the method comprising:
- partitioning a system bandwidth into a plurality of subbands;
- configuring at least one subband among the plurality of subbands;
- and
- communicating with a user equipment (UE) via the configured at least one subband,
- wherein each subband among the plurality of subbands includes 6 consecutive physical resource blocks (PRBs) in a frequency domain, and
- wherein a boundary of a PRB in each subband is aligned with a boundary of a PRB in the system bandwidth.
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- configuring at least one subband among a plurality of subbands, wherein a system bandwidth is partitioned into the plurality of subbands;
- and
- communicating with a base station (BS) via the configured at least one subband,
- wherein each subband among the plurality of subbands includes 6 consecutive physical resource blocks (PRBs) in a frequency domain, and
- wherein a boundary of a PRB in each subband is aligned with a boundary of a PRB in the system bandwidth.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a memory;
- a transceiver;
- and
- a processor, operably coupled to the memory and the transceiver, that:
- configures at least one subband among a plurality of subbands, wherein a system bandwidth is partitioned into the plurality of subbands, and
- controls the transceiver to communicate with a base station (BS) via the configured at least one subband,
- wherein each subband among the plurality of subbands includes 6 consecutive physical resource blocks (PRBs) in a frequency domain, and
- wherein a boundary of a PRB in each subband is aligned with a boundary of a PRB in the system bandwidth.
