Abstract
In one exemplary embodiment, a method includes: dividing a plurality of control channel elements in at least one downlink subframe of a bundling window into a plurality of portions having a first portion and a second portion, where the first portion includes at least one control channel element that is mapped to resources and the second portion includes at least one control channel element that is not mapped to resources, where the bundling window has a plurality of downlink subframes; and sending a last downlink grant in a downlink subframe of the bundling window using at least one control channel element that is mapped to resources.
Claims20
A method comprising:
- dividing a plurality of control channel elements in at least one downlink subframe of a bundling window into a plurality of portions comprising a first portion and a second portion, where the first portion comprises at least one control channel element that is mapped to resources and the second portion comprises at least one control channel element that is not mapped to resources, where the bundling window comprises a plurality of downlink subframes;
- and
- sending a last downlink grant in a downlink subframe of the bundling window using at least one control channel element that is mapped to resources.
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing computer program code,
- the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:
- divide a plurality of control channel elements in at least one downlink subframe of a bundling window into a plurality of portions comprising a first portion and a second portion, where the first portion comprises at least one control channel element that is mapped to resources and the second portion comprises at least one control channel element that is not mapped to resources, where the bundling window comprises a plurality of downlink subframes;
- and
- send a last downlink grant in a downlink subframe of the bundling window using at least one control channel element that is mapped to resources.
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, said operations comprising:
- dividing a plurality of control channel elements in at least one downlink subframe of a bundling window into a plurality of portions comprising a first portion and a second portion, where the first portion comprises at least one control channel element that is mapped to resources and the second portion comprises at least one control channel element that is not mapped to resources, where the bundling window comprises a plurality of downlink subframes;
- and
- sending a last downlink grant in a downlink subframe of the bundling window using at least one control channel element that is mapped to resources.
