Abstract
A communication system is described in which machine-type communication devices having a reduced bandwidth can be allocated physical uplink control channel resources that fall within that reduced bandwidth whilst other, legacy, devices can continue to use physical uplink control channel resources that do not fall within that reduced bandwidth.
Claims4
A communication apparatus comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- transmit a parameter for frequency hopping by a bandwidth limited type user equipment (UE),
- assign a frequency resource for a physical uplink control channel (PUCCH) for the bandwidth limited type UE using the parameter,
- wherein the parameter is different from another parameter, pusch-HoppingOffset, for frequency hopping by the non-bandwidth limited type UE,
- wherein in a first one of two consecutive slots, PUCCH transmission is performed over a first narrowband,
- wherein in a second one of the two consecutive slots, PUCCH transmission is performed over a second narrowband.
A user equipment (UE) configured to communicate using a limited bandwidth, the UE comprising:
- a memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- receive a parameter for frequency hopping by the UE,
- determine a frequency resource which is assigned for a physical uplink control channel (PUCCH) using the parameter,
- perform PUCCH transmission over a first narrowband in a first one of two consecutive slots, and
- perform PUCCH transmission over a second narrowband in a second one of the two consecutive slots,
- wherein the parameter is different from another parameter, pusch-HoppingOffset, for frequency hopping by a non-bandwidth limited type UE.
A method performed by a communication apparatus, the method comprising:
- transmitting a parameter for frequency hopping by a bandwidth limited type user equipment (UE);
- assigning a frequency resource for a physical uplink control channel (PUCCH) for the bandwidth limited type UE using the parameter,
- wherein the parameter is different from another parameter, pusch-HoppingOffset, for frequency hopping by the non-bandwidth limited type UE,
- wherein in a first one of two consecutive slots, PUCCH transmission is performed over a first narrowband,
- wherein in a second one of the two consecutive slots, PUCCH transmission is performed over a second narrowband.
A method for a user equipment (UE) configured to communicate using a limited bandwidth, the method comprising:
- receiving a parameter for frequency hopping for the UE,
- determining a frequency resource which is assigned for a physical uplink control channel (PUCCH) using the parameter;
- performing PUCCH transmission over a first narrowband in a first one of two consecutive slots;
- performing PUCCH transmission over a second narrowband in a second one of the two consecutive slots,
- wherein the parameter is different from another parameter, pusch-HoppingOffset, for frequency hopping for a non-bandwidth limited type UE.
