Problems solved by technology

In case of retransmissions, using mechanisms for signaling resource allocations can greatly limit the possibility of signaling resource allocations for initial transmissions, leading to starvation of new resource allocations in channel conditions experiencing especially degraded

Embodiment Construction

[0027] Figure 1 has been described in connection with the prior art.

[0028] Figure 2 details the message flow between a terminal and a base station when data is sent in the uplink direction using retransmission control according to the present invention.

[0029] Step 21 consists in allocating resources (or PRBs) to terminals UEs that need to transmit uplink data. Preferably, this resource allocation is performed at the base station (enhanced Node B as foreseen by the 3GPP LTE system). However, the entity performing the scheduling need not be the base station. Those skilled in the art will understand that this scheduling can also be performed by any other central entity of the network.

[0030] Step 22 consists in transmitting user data along the uplink by the terminal UE using the allocated resources. Uplink transmissions are distorted at the air interface and cannot be correctly received at the base station.

[0031] Step 23 consists in detecting the erroneous transmis...

Abstract

The present invention relates to a method for allocating resources to a transmitter adapted to send data over a radio link, the data being transmitted in physical resource blocks allocated by a resource allocation mechanism, said physical resource block being defined by its frequency extension and its time extension, an automatic repeat request protocol being used for signaling erroneously and / or correctly received data through a feedback message. According to the present invention, the method is characterized in that it includes the steps of: - including in said feedback message information related to the new frequency extension and / or time extension for the physical resource block to be used in case of further transmission of data by said transmitter.

Description

[0001] The present invention is based on the earlier application EP 07 301 129.8, which is hereby incorporated by reference. technical field [0002] The present invention relates to a method for allocating resources in a mobile radio communication network to a transmitter adapted to transmit data over a radio link to a receiver. Background technique [0003] During radio transmission over a radio link, due to the distortion of the radio signal, it is necessary to constantly track and retransmit some data parts that were not received or were received in error. The ARQ (Automatic Repeat Request) or HARQ (Hybrid Automatic Repeat Request) protocol has been devised for this purpose and applied in most radio communication networks for ensuring the integrity of data transmitted over radio links. In this protocol, each data entity is marked with a sequence number. The task of the receiver is to detect whether all data entities, eg with increasing and consecutive sequence numbers, ...
