Embodiment Construction

[0029] In the following detailed description, devices, methods and software products according to the teachings of the present application will be described by way of embodiments. It should be noted that while only mobile phones, base stations, and servers are described, the teachings of the present application are also applicable to any electronic device operating in a communication network, such as a portable electronic device such as a media player, game console, laptop computer , personal digital assistants, e-books and notepads.

[0030]In the prior art system of Table 1, the system is designed for carrier aggregation with four ACK / NACK bits (enumerated as HARQ-ACK(0) to HARQ-ACK(3)) in FDD. In this document, ACK / NACK bits are interchangeably referred to as uplink information feedback elements. This is the system described in "UL HARQ-ACK multiplexing mapping for 4 bits" (R1-103638) by Samsung.

[0031] For this system, the error probability is different among different...

Abstract

A method for execution on an apparatus configured to operate in a telecommunications network comprising a processor, wherein said processor is configured to execute said method, said method comprising encoding a plurality of uplink feedback information elements for carrier aggregation, by a set of codewords where each codeword comprises a channel, wherein at least two information elements have the same channel distribution.

Description

technical field [0001] The present application relates to a method and a configuration in a communication system, and in particular to a configuration and a method for improving HARQ feedback in a communication system. Background technique [0002] The 3rd Generation Partnership Project (3GPP) is a cooperative agreement uniting many communication standards bodies. Within the 3GPP working group, a new system concept called Long Term Evolution (LTE) and System Architecture Evolution (SAE) is being standardized. figure 1 The architecture of the 3GPP LTE / SAE system (hereinafter referred to as LTE) is schematically illustrated in , which is relatively flat compared to systems based on, for example, GSM (Global System for Mobile Communications) and WCDMA (Wideband Code Division Multiple Access). figure 1 LTE radio base stations 100a, 100b, 100c (in 3GPP terminology denoted eNodeB or eNB) are shown connected directly to core network nodes 101a, 101b via S1 interfaces 102a, 102b, 1...
