A method for data transmission in a wide area mobile network supporting both MIMO User Equipments and non MIMO User Equipments includes allocating in a first signal the traffic of non MIMO user Equipments, a first MIMO data stream and a primary pilot channel, allocating in a second signal a second MIMO data stream and a secondary pilot channel, and transmitting the first signal and the second signal with two orthogonal circular polarizations.

Data transmission in a wide area mobile network

Method and system for dynamically selecting a cell range of a base station connected to User Equipments, according to the distances between each of the User Equipments and the base station, and the percentage of a maximum baseband capacity of the base station used by connections with the User Equipments.

Cell range selection based on UE distance and base station capacity

Method and RNC for selecting transmission technology when a UE enters the network, which checks whether the UE is MIMO and, if so and only one carrier is available, allocates its traffic to said carrier and uses a S-CPICH to provide all MIMO traffic with a diversity pilot and Virtual Antenna Mapping for balance. If more than one carrier is available, the number of UEs, their radio conditions and load of carriers are checked periodically. If the carrier is busy only with MIMO and its load is higher than the load of the remaining carriers, diversity CPICH of STTD is selected; otherwise and only if the UEs vulnerable to STTD with good radio conditions exceed a certain number, the S-CPICH is selected. The RNC can reconfigure the network from transmitting MIMO traffic with STTD to using MIMO with S-CPICH or vice versa dynamically by periodical check of the load and UEs criteria for configuration change.

Selecting transmission technology for communications in wide area mobile networks

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. Also, if the connection is established with HSPDA non MIMO technology and the position variations are below a second pre-defined threshold, the connection is switched to HSPDA MIMO technology.
