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 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: Base station apparatus (1) is provided for improving bandwidth usage in a cellular communication network serving at least one mobile terminal. The network is capable of supporting at least a first radio access technology (i.e. GSM) and a second radio access technology (LTE) and uses a predefined bandwidth range. The apparatus comprises a base band unit (3) including a counting means for determining the number of mobile terminals within a cell of the first radio access technology supporting the second radio access technology and a measuring means for determining the level of traffic carried by the first radio access technology cell; and a bandwidth assignment means for dynamically assigning a first portion of the bandwidth range to the first radio access technology and a second portion of the bandwidth range to the second radio access technology on the basis of the number of supportive mobile terminals and the level of first radio access technology traffic.
