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 resource blocks including a punctured direct current (DC) subcarrier to a low cost UE, and communicating with the low cost UE by using the allocated resource blocks. The allocated resource blocks may not be located at center of a set of resource blocks that the low cost UE can access at a given subframe.
Claims15
A method for transmitting system information for a narrowband user equipment (UE) in a wireless communication system, the method comprising:
- transmitting, by a base station (BS), the system information for the narrowband UE via a first narrowband in a first subfrarme;
- and
- transmitting, by the BS, the system information for the narrowband UE via a second narrowband in a second subframe
- wherein a frequency location of the first narrowband for the narrowband UE is determined by a cell identifier (ID), a system bandwidth, and information related to the first subframe, and
- wherein a frequency location of the second narrowband for the narrowband UE is determined by the cell ID, the system bandwidth, and information related to a second subframe.
A method for receiving system information in a wireless communication system, the method comprising:
- receiving, by a narrowband user equipment (UE) from a base station (BS), the system information via a first narrowband in a first subframe;
- and
- receiving, by the narrowband UE from the BS, the system information via a second narrowband in a second subframe
- wherein a frequency location of the first narrowband for the narrowband UE is determined by a cell identifier (ID), a system bandwidth, and information related to the first subframe, and
- wherein a frequency location of the second narrowband for the narrowband UE is determined by the cell ID, the system bandwidth, and information related to a second subframe.
A base station (BS) in a wireless communication system, the BS comprising:
- a memory;
- a transceiver;
- and
- a processor, coupled to the memory and the transceiver, that:
- transmits the system information for the narrowband UE via a first narrowband in a first subfrarme, and
- transmits the system information for the narrowband UE via a second narrowband in a second subframe,
- wherein a frequency location of the first narrowband for the narrowband UE is determined by a cell identifier (ID), a system bandwidth, and information related to the first subframe, and
- wherein a frequency location of the second narrowband for the narrowband UE is determined by the cell ID, the system bandwidth, and information related to a second subframe.
