Embodiment Construction

[0019] In the following description, for purposes of explanation and not limitation, specific details are set forth (eg, specific architectures, interfaces, techniques, etc.) in order to provide a thorough understanding. In other instances, detailed descriptions of known devices, circuits, and methods are omitted so as not to obscure the description with unnecessary detail. Throughout the description, the same reference numbers refer to the same or similar elements.

[0020] figure 1 An environment in which embodiments of the invention may be implemented is schematically illustrated. In particular, a communication system 1 is shown comprising a first base station 2 (e.g. an evolved Node B (also denoted eNB or eNodeB) in Long Term Evolution (LTE), arranged to communicate with a user using radio frequency transmitters and receivers The devices 8, 9 communicate (for example, utilizing multiple-input multiple-output (MIMO) antenna technology). The communication system 1 may be a...

Abstract

The invention relates to a method 20 performed in a user equipment 8 for estimating interference within a serving cell 5 of a communication system 1 . The user equipment 8 is connected to the serving cell 5 and the communication system 1 also comprises one or more neighboring cells 6 , 7 of the serving cell 5 . The method 20 comprises: receiving 21 a neighboring cell reference signal transmitted in at least one of the neighboring cells 6, 7 and a serving cell reference signal transmitted in the serving cell 5; and determining 22 a first interference estimate of the interference within the serving cell 5 , the first interference estimate takes into account the cancellation of interference from neighboring cell reference signals. The invention also relates to user equipment, computer programs and computer program products.

Description

technical field [0001] The techniques disclosed herein relate generally to the field of wireless communication systems, and in particular to interference estimation within such wireless communication systems. Background technique [0002] To provide increased capacity to mobile users, heterogeneous networks (HetNets) are attractive solutions and are expected to be widely deployed in the near future. HetNet includes various types of cells such as macro cells, pico cells and femto cells. In a typical deployment, a macro base station provides wide area coverage to serve users within a macro cell. Within the macrocell there will be areas with high traffic (ie high user concentration) and areas lacking coverage (coverage holes). In those areas, it would be desirable to deploy additional capacity to keep users happy. In HetNet, additional capacity is provided by deploying access nodes within a macro cell in order to concentrate capacity boosts to smaller areas where capacity is...
