    摘要： An antenna is described, which has a conductive annulus arranged on the surface of a flat planar dielectric substrate. The antenna comprises first and second lands of conductive material which are also arranged on the surface of the substrate, outside the annulus. The first conductive land provides a part of a first port for exciting a first polarisation mode of the antenna. The second conductive land provides a part of a second port for exciting a second polarisation mode of the antenna, orthogonal to the first mode. The antenna may be used for multiple-input, multiple-output (MIMO) operation.

    摘要： A a method (101) for rolling out a mobile network (100) using carrier aggregation comprising a sector fitted with multiple cells, said method comprising:
    - gathering data (A) from a plurality of network counters associated with two or more cells of said multiple cells;
    - detecting (B1) a network congestion situation (Cs), based on a minimal throughput level (Tm) and an aggregate cumulative distribution function (CDF, g), wherein said aggregate CDF (g) depends on said plurality of network counters;
    - identify (B2) one or more cells effecting said congestion situation (Cs) among said two or more cells;
    - determine (B3) for each of said identified one or more cells whether a capacity (PP-cap) or coverage pain point (PP-cov) is associated with said congestion situation (Cs).

    摘要： For establishing wireless communication between a train (2) and a plurality of base stations (B1, B2), arranged along a track (3) travelled by the train (2), a Multiple-Input and Multiple-Output array (M2) is established which includes at least two communication relays (R4, R5, R6) arranged on the train (2) and one or more of the base stations (B1, B2). Communication is performed concurrently via multiple communication channels (h1a, h1b, h1c, h2a, h2b, h2c) of the Multiple-Input and Multiple-Output array (M2) using cooperative communication schemes. channel state information is stored in a data store and, for communicating via the communication channels (h1a, h1b, h1c, h2a, h2b, h2c) of the Multiple-Input and Multiple-Output array (M2), channel state information is determined depending on information defining the current location of the communication relays (R4, R5, R6).
