Abstract
A communication system is disclosed in which a base station communicates with machine-type-communication (MTC) devices by dividing the base station's cell bandwidth into (non-overlapping) narrowbands. The base station identifies, based on a communication received from a communication device, a capability of that communication device to retune between narrowbands, and provides, to that communication device, control information for controlling how that communication device retunes between different narrowbands, wherein the control information is based on the identified capability of that communication device to retune between narrowbands.
Claims9
A method for a user equipment (UE), the method comprising:
- communicating using any of a plurality of narrowbands;
- sending, to a base station in radio resource control (RRC) signalling, a UE capability information element indicating a capability of retuning from a first narrowband to a second narrowband within a retuning period of a single symbol;
- and
- not transmitting a last symbol in a first subframe, in accordance with a shortened physical uplink control channel (PUCCH) format, in a case where the UE capability information element indicates that the UE is capable of retuning within the retuning period of a single symbol.
A method for a base station, the method comprising:
- communicating with a user equipment (UE), using any of a plurality of narrowbands;
- receiving, from the UE, in radio resource control (RRC) signalling, a UE capability information element indicating a capability of retuning from a first narrowband to a second narrowband within a retuning period of a single symbol;
- and
- not receiving transmissions from the UE in a last symbol in a first subframe, in accordance with a shortened physical uplink control channel (PUCCH) format, in a case where the UE capability information element indicates that the UE is capable of retuning within the retuning period of a single symbol.
A user equipment (UE) comprising:
- a controller;
- and
- a transceiver,
- wherein the controller is configured to:
- control the transceiver to communicate using any of a plurality of narrowbands;
- control the transceiver to send, to a base station in radio resource control (RRC) signalling, a UE capability information element indicating a capability of retuning from a first narrowband to a second narrowband within a retuning period of a single symbol;
- and
- control the transceiver not to transmit in a last symbol in a first subframe, in accordance with a shortened physical uplink control channel (PUCCH) format, in a case where the UE capability information element indicates that the UE is capable of retuning within the retuning period of a single symbol.
