Embodiment Construction

[0035] Fig. 1 shows a schematic diagram of network elements of a mobile network 1 according to a preferred embodiment of the present invention. The mobile network 1 can be used in wireless communication systems according to third generation standards. The receiver device 2 (part of the user equipment 3 ) is therefore described below in connection with downlink transmission from the UMTS terrestrial radio access network 4 to the peripheral network 6 connected via the core network 5 . However, the receiver apparatus 2 and receiving method are also applicable to other environments, or may be included in or processed by other types of equipment.

[0036] The network 4 includes radio network controllers 7 , 8 , wherein the radio network controller 7 is connected to the radio network controller 8 via an interface 9 . In addition, the network 4 also includes base stations 10 , 11 , wherein the base station 10 is connected to the radio network controller 7 through the interface 12 , ...

Abstract

When transmitting medium access control protocol data units for the high speed downlink shared channel over a plurality of hybrid automatic repeat request processes, one of the processes can be in a retransmission procedure. In this case, stalling of the transmission can occur, because the medium access control layer for the high speed downlink shared channel of the receiver apparatus (3) buffers the following packet data units, when a preceding protocol data unit is waiting in the stalled process. To enable an early processing of the already received data, the receiver apparatus determines, whether the next expected service data units for a higher layer such as a radio link control layer, are included in the already received packet data units by taking into account the sequence number for the higher layer. Therefore, the medium access control layer for the high speed downlink shared channel accesses the data of the service data unit for the higher layer.

Description

field of invention [0001] The invention relates to a device and a method for receiving data units over a channel. In particular, the present invention relates to an apparatus and method for receiving a data unit over a high speed downlink shared channel of a wireless communication system according to the third generation standard of Universal Mobile Telecommunications System (UMTS). technical background [0002] Prior art document WO 2004 / 019543 A1 describes a method for a hybrid automatic repeat request procedure in a mobile communication system. Accordingly, multiple Hybrid Automatic Repeat Request (HARQ) processes transmit data packets from a transmitter to a receiver, one of which is reserved for a particular data flow of high priority. More prior art content can be found in "3GPP TS 25.321 V5.7.0 (2003-12) Technical Specification 3 rd Generation Partnership Project; Technical Specification Group RadioAccess Network; Medium Access Control (MAC) protocol specification (...
