Problems solved by technology

This has the problem that the first Node B may be waiting for a block so that it can be delivered to the RNC, but some other Node B may have already received the same block, so the user terminal will not retransmit it
This results in rather complex MAC-hs PDU header structures, especially at low data rates resulting in overhead

Embodiment Construction

[0045] Fig. 1 illustrates the structure of a wireless system. The wireless system may be based on eg GMS (Global System for Mobile Communications). UMTS (Universal Mobile Telephone System) or WCDMA (Wideband Code Division Multiple Access).

[0046] The core network may eg correspond to a combined structure of the GSM and GPRS (General Packet Radio System) systems. GSM network elements are responsible for implementing circuit-switched connections, while GPRS network elements are responsible for implementing packet-interactive connections, however some network elements are shared by both systems.

[0047] A Mobile Services Switching Center (MSC) 100 implements circuit switched signaling in a wireless system. Serving GPRS Support Node (SGSN) 101 in turn implements packet switched signaling. All services in the wireless system can be controlled by MSC100.

[0048] The core network may have a gateway unit 102, which stands for a Gateway Mobile Services Switching Center (GMSC), ...

Abstract

In a radio system data units are associated with sequence numbers in a user terminal. The data units are arranged in order of the sequence numbers associated with the data units in the network element of the radio system.

Description

technical field [0001] The invention relates to a communication method, a user terminal, a network element and a computer program in a wireless system. Background technique [0002] In wireless systems such as WCDMA (Wideband Code Division Multiple Access) or UMTS (Universal Mobile Telecommunications System), with packet-switched connections, packets are usually protected from noise, fading by channel coding such as FEC (Forward Error Correction Coding) and interference. Reception of packets may fail despite protection, which can be compensated by retransmission. A retransmission occurs when the receiving transceiver of a packet requests that one or more packets with errors be repeated. This can be performed by an ARQ (Automatic Repeat Request) mechanism. In a receiver utilizing HARQ (Hybrid ARQ), packets with errors and retransmitted packets can be combined to increase the probability of correctly receiving packet information. According to the OSI (Open Standard Interco...
