Abstract
A method of wireless communication provides narrow bandwidth operation within a wider LTE system bandwidth. Wideband information is transmitted to a first set of user equipments (UEs). Also, narrowband information is transmitted to a second set of UEs. The second set of UEs operate in a narrower bandwidth than the first set of UEs.
Claims21
A method of wireless communication at a first type of user equipment (UE) operable in a narrow bandwidth, comprising:
- receiving, in the narrow bandwidth, at least a portion of a first reference signal, control information, and data, the narrow bandwidth narrower than a wide bandwidth in which a second type of UE can be operable, and the first reference signal different than a second reference signal that can be received at the second type of UE, wherein the second reference signal spans the wide bandwidth, wherein the first reference signal and the second reference signal are downlink reference signals;
- and
- performing channel measurements based on at least the portion of the first reference signal;
- and
- transmitting results of the channel measurements based on at least the portion of the first reference signal.
A first type of user equipment (UE) operable in a narrow bandwidth, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor configured to:
- receive, in the narrow bandwidth, at least a portion of a first reference signal, control information, and data, the narrow bandwidth narrower than a wide bandwidth in which a second type of UE can be operable, and the first reference signal different than a second reference signal that can be received at the second type of UE, wherein the second reference signal spans the wide bandwidth, wherein the first reference signal and the second reference signal are downlink reference signals;
- and
- perform channel measurements based on at least the portion of the first reference signal;
- and
- transmit results of the channel measurements based on at least the portion of first reference signal.
A first type of user equipment (UE) operable in a narrow bandwidth, comprising:
- means for receiving, in the narrow bandwidth, at least a portion of a first reference signal, control information, and data, the narrow bandwidth narrower than a wide bandwidth 1n which a second type of UE can be operable, and the first reference signal different than a second reference signal that can be received at the second type of UE, wherein the second reference signal spans the wide bandwidth, wherein the first reference signal and the second reference signal are downlink reference signals;
- and
- means for performing channel measurements based on at least the portion of the first reference signal;
- and
- means for transmitting results of the channel measurements based on at least the portion of first reference signal.
A non-transitory computer-readable medium storing computer executable code, the code when executed by a processor cause the processor to:
- receive, in a narrow bandwidth, at least a portion of a first reference signal, control information, and data, the narrow bandwidth in which a first type of user equipment (UE) is operable being narrower than a wide bandwidth in which a second type of UE can be operable, and the first reference signal different than a second reference signal that can be received at the second type of UE, wherein the second reference signal spans the wide bandwidth, wherein the first reference signal and the second reference signal are downlink reference signals;
- and
- perform channel measurements based on at least the portion of the first reference signal;
- and
- transmit results of the channel measurements based on at least the portion of first reference signal.
