Abstract: To determine which traffic and terminal types and in which parts of a call should be best served by a given carrier there is provided a method and system for dynamically allocating carriers in a MIMO network using S-CPICH. The consideration of which carrier to allocate addresses problems caused by the enablement of the diversity transmission technique. Carriers are dynamically allocated to terminals in a WCDMA network scenario taking into account each terminal's vulnerability to interference from a carrier using S-CPICH or STTD according to certain parameters, such as a requested service or the radio conditions at any given time. The carriers are allocated from carriers using P-CPICH, S-CPICH and/or STTD. The invention also relates to a system that implements this method in a WCDMA network.

Abstract: System and method for transmitting a radio signal in a mobile communication network. The radio signal has a circular polarisation.

Abstract: Method and RNC for selecting a transmission technology to MIMO UEs, HSDPA UEs and non-HSDPA UEs of a network with multiple carriers, comprising: checking whether the UE is a MIMO UE; using STTD on at least one radio carrier and allocating MIMO traffic to it, checking whether the UE is a HSDPA UE vulnerable to STTD and comparing the radio conditions with at least one quality threshold, and if the UE is vulnerable to STTD and the radio conditions are equal to or higher than the first quality threshold (good radio conditions), allocating its traffic to any of the remaining radio carriers free of MIMO traffic; if the UE is vulnerable to STTD and the radio conditions are lower than the first quality threshold (medium or bad radio conditions), allocating its traffic to any carrier on a frequency selection basis, for example, relative load among carriers.

Abstract: The invention refers to a method for scheduling traffic in a communication channel of a mobile communications network which detects small sized data bursts and prioritizes their transmission. The detection is performed by comparison with two thresholds, one being an indicator of the instantaneous size of the data burst and the second one being related to the size of said data burst along a given period of time. The invention is also related to a network scheduler comprising means for carrying out the above method.

Abstract: The present invention discloses a method for selecting a transmission technology (MIMO or non MIMO) for a HSDPA connection established between a RNC and a UE depending on the mobility of said UE, measured at the RNC as variations of the position of the UE. Then, if the connection is established with HSDPA MIMO technology and the position variations exceed a first pre-defined threshold, the connection is switched to HSPDA non MIMO technology.

Abstract: Within the 3G networks, the HSDPA use a scheduler in the Node B that has to be optimised to differentiate traffic/users to provide the appropriate Quality of Service to everyone. There are several kinds of application/user that need different QoS priorities not only in terms of throughput but also in terms of delay. Most of the algorithms for HSDPA scheduler work based on throughput and some of them also are based on delay but with complicated functions difficult to implement in the HW of the current 3G networks. It is needed to simplify the algorithms. This invention allows a more efficient control of the delay of the traffic involved in the different applications in the 3G networks when going through the HSDPA scheduler and also guarantees the best Quality of Service (QoS) to the customers.
