A cellular telecommunications network architecture is described where certain UEs are configured to assist the network to improve coverage in regions of poor radio conditions. In certain embodiments, appropriate UEs are selected to act as a dynamic, out-of-band coverage extensions. Network performance can thereby be improved when serving users at the cell edge (or in other poor radio condition regions of a cell).

Telecommunication system

By first determining whether network conditions make it possible and necessary to assist the network in supporting communication devices in comparatively poor radio coverage, and then periodically determining what type of assistance would best improve the overall network performance, a cellular telecommunications network is dynamically adapted to improve overall network performance without requiring the introduction of new network equipment. In one example, the dynamic activation of the radio coverage assistance serves to reduce problems associated with users at the cell edge, resulting in improvements in overall cell capacity.

Reducing energy consumption in mobile telecommunications

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.
