Abstract
Techniques are described for permitting uplink feedback for downlink transmission over downlink-only RF carriers to occur using uplink control channels belonging to another fully-configured RF carrier herein known as a primary carrier. Uplink feedback channels can be allocated for the downlink-only RF carriers in the uplink control regions of a fully-configured RF carrier immediately following the uplink control channels for the primary carrier are allocated. The uplink feedback channels for downlink-only RF carriers can be allocated based on global or local index number of each downlink-only RF carrier in sequential order based on ascending or descending sorting of the index numbers.
Claims24
A method, performed at a base station, the method comprising:
- requesting to schedule and allocate uplink control channels for at least one primary uplink control channel;
- requesting to schedule and allocate a first uplink control channel for a downlink-only carrier;
- and
- requesting to schedule and allocate a second uplink control channel for a second downlink-only carrier, wherein the requesting to schedule and allocate a first uplink control channel for a downlink-only carrier comprises:
- requesting to schedule and allocate a first uplink control channel for a downlink-only carrier in one or more logical resource units immediately after one or more logical resource units allocated for the primary uplink control channels and a logical resource unit for the first uplink control channel having a physical or logical index number.
A method, performed at a mobile station, the method comprising:
- requesting feedback to be provided in allocated uplink control channels for at least one primary uplink control channel;
- requesting feedback to be provided in an allocated first uplink control channel for a downlink-only carrier;
- and
- requesting feedback to be provided in an allocated second uplink control channel for a second downlink-only carrier, wherein the first uplink control channel for a downlink-only carrier is allocated in one or more logical resource units immediately following one or more logical resource units allocated for the primary uplink control channel and a logical resource unit for the first uplink control channel having an index number.
A system comprising:
- one or more antennae;
- a display device;
- a processor communicatively coupled to the display device and the one or more antennae, the processor configured to:
- request feedback to be provided in allocated uplink control channels for at least one primary uplink control channel,
- request feedback to be provided in an allocated first uplink control channel for a downlink-only carrier, and
- request feedback to be provided in an allocated second uplink control channel for a second downlink-only carrier, wherein the first uplink control channel for a downlink-only carrier is allocated in one or more logical resource units immediately after one or more logical resource units allocated for the primary uplink control channel and a logical resource unit for the first uplink control channel has an associated index number.
