Method for Coordinating Uplink Resource Allocation

Abstract

The invention relates to a method for allocating uplink radio resources in a cellular radio communication system comprising: at least one first cell associated with a first control node and a cell served by said first cell or more first mobile stations, and at least one second cell associated with a second control node and one or more second mobile stations served by said second cell; and said method comprises the steps of: The first control node groups the one or more first mobile stations into at least two different groups according to the interference impact of the first mobile stations on the second cell; the first control node based on the grouping allocating uplink radio resources of the first cell for the one or more first mobile stations, thereby obtaining a first radio resource allocation pattern for the one or more first mobile stations; the The first control node transmits a first message including the first radio resource allocation mode; the second control node receives the first message including the first radio resource allocation mode; and the second control node based on the The first radio resource allocation mode allocates uplink radio resources of the second cell to one or more second mobile stations. Furthermore, the invention also relates to a method in a first control node, a method in a second control node, a first control node device, a second control node device, a computer program, and a computer program product thereof.

Description

technical field [0001] The invention relates to a method for allocating uplink radio resources in a cellular radio communication system. Furthermore, the invention also relates to a method in a first control node, a method in a second control node, a first control node device, a second control node device, a computer program, and a computer program product thereof. Background technique [0002] In a heterogeneous network (HetNet, Heterogeneous Network) environment, when more and more cells and mobile stations such as user equipment (UE, User Equipment) become part of the network, the interference in the network will also become more and more complex. The interference situation together with the imbalance of uplink (UL, uplink) and downlink (DL, downlink) interference and the huge uplink interference variation poses a great challenge to the network. [0003] In order to better utilize the radio resources of small cells (such as microcells, picocells and femtocells), differe...

Problems solved by technology

The disadvantage of this choice is: Since the small cell cannot predict the interference level of TTI6, if the next TTI is low interference, the selected MCS is too conservative and will reduce the spectral efficiency

[0040] However, in this solution, although the macro base station has detected the interfering device and also limited the interference in the frequency domain (or carrier domain), the information utilization in the small cell is still not optimistic
