Method and apparatus in a telecommunication system
First Claim
1. A method in a communication unit acting as a data receiving party and employing a TDD or half duplex FDD arrangement when communicating with a data sending party, of transmitting feedback reports for data blocks received in receive (RX) sub-frames to indicate whether errors have occurred in the data blocks, said method comprising the following steps:
- obtaining allocation parameters for a connection indicating that a number of required feedback reports is greater than a number of allowed feedback reports during a given sub-frame sequence, andscheduling feedback reports in available transmit (TX) sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames.

Abstract
Method and apparatus in a communication unit (400) employing a wireless TDD or half duplex FDD transmission arrangement when communicating with a data sending party, for scheduling feedback reports for data blocks in received RX sub-frames, in TX sub-frames available for transmission. An obtaining unit (402) in the communication unit receives allocation parameters (P) for the connection where the number of required feedback reports is greater than the number of allowed feedback reports. A scheduling unit (404) in the communication unit then schedules feedback reports (FR) in available TX sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. In this way, the number of feedback reports in a TX sub-frame can be reduced.

15. An apparatus in a communication unit acting as a data receiving party and employing a TDD or half duplex FDD arrangement when communicating with a data sending party, for transmitting feedback reports for data blocks received in receive (RX) sub-frames to indicate whether errors have occurred in the data blocks, said apparatus comprising:
-
an obtaining unit adapted to obtain allocation parameters for a connection indicating that a number of required feedback reports is greater than a number of allowed feedback reports during a given sub-frame sequence, and a scheduling unit adapted to schedule feedback reports in available transmit (TX) sub-frames according to a predetermined spreading rule also known by the data sending party, dictating that the feedback reports are spread out or distributed evenly over the available TX sub-frames. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
