20130316700 | APPARATUS AND METHOD FOR REDUCING INTERFERENCE - An infrastructure apparatus for reducing interference, the apparatus comprising a controller. The controller is arranged in operation to determine an amount of interference in a first frequency band to radio signals for a first type of traffic caused by radio signals for a second type of traffic in a second frequency band, wherein the radio signals for the first type of traffic are to and/or from a first group of one or more base stations; and the radio signals for the second type of traffic are to and/or from a second group of one or more base stations. The controller is further arranged in operation to, in response to the determined interference, generate instructions to influence the second group in respect of the transmission of the radio signals for the second type of traffic in the second frequency, wherein the controller is further operable to generate the instructions using a priority for the first type of traffic and a priority for the second type of traffic. In one example, the first group of one or more base stations may be providing communications services to human to human communications (H2H), whereas the second group of one or more base stations may be providing communications services supporting machine type communications (MTC), where H2H communications are prioritizes over machine type communications. The second group of one or more base stations is therefore instructed to take action to reduce the interference caused b the mobile unit. | 11-28-2013 |
20130329592 | SYSTEM AND METHOD FOR REDUCING INTERFERENCE - A mobile communications system comprises a first group of one or more base stations which are arranged to communicate signals with mobile units via a wireless access interface by transmitting and/or receiving radio signals within a first frequency band; a second group of one or more base stations which are arranged to communicate signals with mobile units via a wireless access interface by transmitting and/or receiving radio signals within a second frequency band; and a controller. The controller is arranged in operation to determine an amount of interference in the first frequency band to radio signals for a first type of traffic where the interference is caused by radio signals for a second type of traffic in the second frequency band, wherein: the radio signals for the first type of traffic are to and/or from a first base station of the first group; and the radio signals for the second type of traffic are to and/or from to a second base station of the second group; and to, in response to the determined interference, generate instructions to influence fluence the second group in respect of the transmission of the radio signals for the second type of traffic in the second frequency band, wherein the instructions are generated based on at least a priority for the first type of traffic and a priority for the second type of traffic. In one example, the first group of one or more base stations may be providing communications services to human to human communications (H2H), whereas the second group of one or more base stations may be providing communications services supporting machine type communications (MTC), where H2H communications are prioritizes over machine type communications. The second group of one or more base stations is therefore instructed to take action to reduce the interference caused by the mobile unit. | 12-12-2013 |

The signal processor is arranged to allocate the uplink resource for the at least one wireless communication unit in a first portion of a first sub-frame on a first frequency and a first portion of a second sub-frame on a second frequency wherein a time gap is allocated between an end of the first portion of the first sub-frame and a beginning of the first portion of a second sub-frame. | 02-13-2014 |
20140112143 | MOBILE COMMUNICATIONS SYSTEM, INFRASTRUCTURE EQUIPMENT, BASE STATION AND METHOD - A mobile communications system including one or more mobile communications devices and a mobile communications network, the mobile communications network including a radio network part and a core network part and being configured to communicate data packets to and/or from mobile communications devices. Data packets can be communicated to or received from the mobile communications devices using either a broadband packet network or a dedicated messaging network. The dedicated messaging network is arranged to communicate short data grams more efficiently than larger data communications. Therefore by selecting either the dedicated messaging network or the broadband network as a function of content of the data packet a more efficient use of available communications resources and hardware resources is realized. | 04-24-2014 |
