Embodiment approach

[0159] The present method for sending and / or receiving information may be implemented by one or more processors in the base station 110 and the user equipment 130 and a computer program for performing the functions of the present method. The above-mentioned program code can be provided as a computer program product, for example in the form of a data carrier carrying a computer program code which, when loaded into a processor unit, performs the method according to the respective method steps. The data carrier may be eg a CD ROM disc, a memory stick or any other suitable medium such as a disc or magnetic tape capable of storing machine readable data. The computer program code is further provided as pure program code on a server and downloaded remotely to the base station 110 and / or user equipment 130 .

[0160] Thus, a computer readable medium encoded with a computer program for receiving information is capable of performing the method according to at least some of the method st...

Abstract

A method for use in a cellular communications TDD system, the system comprising at least a first controlling transceiver and a number of user terminals within a geographical area in the system. The controlling receiver controls the traffic to ( down link ) and from ( uplink ) said user terminals. The uplink traffic can comprise both scheduled and non- scheduled traffic, and the scheduled uplink traffic is preceded by uplink scheduling information. A number of user terminals in the system transmit continuously in a non- scheduled uplink channel of the system, said transmissions involving at least one of the following: some of said scheduling information, data traffic, a bit stream according to a pre-defined format.

Description

technical field [0001] The present invention relates to a method and a device in a user equipment and a method and a device in a base station. More specifically, the present invention relates to an improved mechanism for uplink access in a wireless communication system. Background technique [0002] Currently, standard commercial radio access technologies for wireless communication systems are growing rapidly. These radio access technologies include cellular communication systems operating on the Time Division Duplex (TDD) principle. An example of a cellular wireless communication system operating in TDD is a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system. [0003] In a TD-SCDMA system, as in other cellular radio communication systems, there is a first transceiver (a so-called base station, or in this case a so-called Node B) which controls Traffic from user terminals within a geographical area (cell) of a wireless communication system. [0004...
