Problems solved by technology

[0009] 1. DL or UL data arrives when UL is not synchronized during RRC_CONNECTED;
[0010] 2. UL data arrives, but no dedicated PUCCH resources are available for D-SR transmission;
[0024] The downside is that it degrades the end-user experience for user devices connected to the network over relay nodes
User equipment will experience a sudden and prolonged service interruption

Embodiment Construction

[0046]The functions of the various elements shown in the figures, including any functional blocks labeled "processors", may be provided through the use of dedicated hardware as well as hardware capable of executing software in combination with appropriate software. When the functionality is provided by a processor, the functionality may be provided by a single dedicated processor, by a single shared processor, or by multiple separate processors, some of which may be shared. Furthermore, explicit use of the terms "processor" or "controller" should not be construed to refer exclusively to hardware capable of executing software, but may implicitly include, but is not limited to, digital signal processor (DSP) hardware, Network processors, Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), Read Only Memory (ROM) for storing software, Random Access Memory (RAM), and nonvolatile memory. Other conventional and / or custom hardware may also be incl...

Abstract

The present invention relates to a method for performing a random access procedure by a relay node operating in inband relaying mode in a wireless or radio communication network, comprising at least one base station adopted to communicate over a backhaul link with at least one relay node, said relay node being adapted to communicate over an access link with at least one user equipment, According to the present invention, the method comprises the steps of: -Configuring resources for said backhaul link and for said access link to be time-multiplexed at said relay node, -Sending messages of said random access procedure on resources configured for said backhaul link.

Description

technical field [0001] The present invention relates to the field of telecommunications, and more particularly to a method for performing a random access procedure by a relay node in a wireless or radio communication network. Background technique [0002] Relay-based wireless or radio communication networks are of increasing interest due to their ability to achieve enhanced coverage while keeping the additional required energy within range. More precisely, coverage at high data rates, group mobility, temporary network deployment cell edge throughput and / or coverage in new areas can be greatly improved by introducing relays in conventional wireless / radio communication networks. [0003] Such relay-based wireless or radio communication networks are being studied specifically within the framework of the 3GPP LTE (Long Term Evolution) or IEEE 802.16i / m standardization work. [0004] figure 1 shows the overall architecture of a relay based wireless / radio communication network, ...
