摘要:
A multiple-layered cellular communications system (2c, 2d) particularly adapted to mobile phones and LAN type communication is provided with an overlaid arrangement of cell transceivers. By having this overlay, multiple service providers can provide a cooperative method of load sharing. The usage of the frequency spectrum can be improved and an advance hand-off (16a, 16b) arrangement can be used to prevent or reduce the possibility of blocked calls due to cell saturation (6a, 6b).

A spectrum Sharing Controller comprises: an interface to a sharable spectrum, wherein the sharable spectrum is assigned to a first hierarchy level; a processor configured to enable a first entity for accessing at least part of the sharable spectrum on the first hierarchy level, wherein the processor is configured to assign a second hierarchy level to the at least part of the sharable spectrum accessible to the first entity, and wherein the processor is configured to enable a second entity for accessing at least part of the sharable spectrum on the second hierarchy level.
摘要:
The present invention provides an information transmission method, device and system. The information transmission method in embodiments of the present invention includes: sending, by a first communication node, downlink control information to one or more second communication nodes within a downlink control domain of a first time unit; and preforming, by the first communication node, transmission of data with the one or more second communication nodes according to the downlink control information, where the data is at least one of downlink data and uplink data; the first time unit includes the downlink control domain and a data domain, and there are a preset length of resources between a start position of the first time unit and a start position of the downlink control domain.
摘要:
Reallocation of a capacity boost cell between first and second operators in a cellular radio communications network is carried out by detecting a drop in load for the first operator, in the area of coverage of the capacity boost cell, below a first threshold, and reallocating automatically the capacity boost cell to the second operator in response to the detected drop in load, if the first operator has authorised a reallocation. The capacity boost cell can be reallocated automatically back to the first operator in response to detecting a subsequent increase in load above a second threshold for the first operator. This can improve utilisation of the capacity boost cell during low load periods while still having it available for the first operator for high load periods, and can provide access to additional capacity for the second operator without need for costly additional infrastructure.
