Abstract
A predetermined parameter is used to determine a rate of uplink radio resources to downlink radio resources. Then an uplink radio resource is mapped to a unique one of the downlink radio resources dependent at least in part on the rate. There is then received on the mapped unique one of the downlink radio resources a reply to the uplink radio resource. Apparatus and computer programs are also described, for both a user equipment and a network node.
Claims32
A method comprising:
- using a predetermined parameter to determine by an apparatus a ratio of uplink radio resources to downlink radio resources;
- mapping an uplink radio resource to a unique one of the downlink radio resources dependent at least in part on the ratio, wherein the uplink radio resource is a resource over which the apparatus sends its transmission and the unique one of the downlink radio resources is a resource for transmitting a reply to the transmission sent over the uplink radio resource, and wherein mapping the uplink radio resource to a unique one of the downlink radio resources comprises determining an index of a downlink physical hybrid automatic repeat request indicator channel based at least in part on a physical resource block index of the transmission sent over the uplink radio resource and on the ratio;
- and
- receiving on the mapped unique one of the downlink radio resources a reply to an uplink transmission on the uplink radio resource, wherein the reply informs whether or not the uplink transmission on the uplink radio resource was successfully received.
1 more element
An apparatus comprising:
- a memory storing program instructions;
- and
- a processor;
- in which the processor is configured with the memory and program instructions to cause the apparatus to at least:
- determine a ratio of uplink radio resources to downlink radio resources using a predetermined parameter;
- map an uplink radio resource to a unique one of the downlink radio resources dependent at least in part on the ratio, wherein the uplink radio resource is a resource over which the apparatus sends its transmission and the unique one of the downlink radio resources is a resource for transmitting a reply to the transmission sent over the uplink radio resource, and wherein mapping the uplink radio resource to a unique one of the downlink radio resources comprises determining an index of a downlink physical hybrid automatic repeat request indicator channel based at least in part on a physical resource block index of the transmission sent over the uplink radio resource and on the ratio;
- and
- receive on the mapped unique one of the downlink radio resources a reply to an uplink transmission on the uplink radio resource, wherein the reply informs whether or not the uplink transmission on the uplink radio resource was successfully received.
5 more elements
A non-transitory memory embodying a program of machine-readable instructions, executable by a digital data processor, to perform actions directed to configure an apparatus to map a downlink radio resource to a related uplink radio resource, the actions comprising:
- using a predetermined parameter to determine a ratio of uplink radio resources to downlink radio resources;
- mapping an uplink radio resource to a unique one of the downlink radio resources dependent at least in part on the ratio, wherein the uplink radio resource is a resource over which the apparatus sends its transmission and the unique one of the downlink radio resources is a resource for transmitting a reply to the transmission sent over the uplink radio resource, and wherein mapping the uplink radio resource to a unique one of the downlink radio resources comprises determining an index of a downlink physical hybrid automatic repeat request indicator channel based at least in part on a physical resource block index of the transmission sent over the uplink radio resource and on the ratio;
- and
- receiving on the mapped unique one of the downlink radio resources a reply to an uplink transmission on the uplink radio resource, wherein the reply informs whether or not the uplink transmission on the uplink radio resource was successfully received.
1 more element
A method comprising:
- receiving a transmission from a user equipment on an uplink radio resource;
- using a predetermined parameter to determine by an apparatus a ratio of uplink radio resources to downlink radio resources;

- and
- sending on the mapped unique one of the downlink radio resources a reply to the transmission received on the uplink radio resource, wherein the reply informs whether or not the transmission received on the uplink radio resource was successfully received.
2 more elements
An apparatus comprising:
- a memory storing program instructions;
- and
- a processor;
- in which the processor is configured with the memory and program instructions to cause the apparatus to at least:
