摘要： In a telecommunications system that employs frequency hopping techniques, network performance can be significantly improved by taking into consideration the level of interaction (e.g., the collision rate) between frequency hopping sequences, when allocating the frequency hopping sequences, throughout the network. In a cellular network, this may be accomplished by deriving a network performance measure as a function of a current allocation of frequencyhopping sequences for a number of cells and as a function of an expected collision rate (between the frequency hopping sequences) that appear for the current allocation. The frequency hopping sequences are then re-allocated amongst one or more cells until network performance is optimized. The allocation of frequency hoppingsequences that results in optimized network performance may then be used for assigning frequency hopping sequences to new or existing connections (e.g., cellular calls) within a corresponding cell.

摘要： Users of a given service in a wireless communication system that includes a plurality of multi-service subsystems are allocated to one of the subsystems in accordance with a combined capacity region of the wireless communication system. The combined capacity region is determined based upon capacity regions of each of the plurality of multi-service subsystems. The capacity regions of the plurality of multi-service subsystems are determined using a relative decrease in users of a first service as a function of an increase in users of a second service.

摘要： In a cellular radio telecommunications system that employs frequency hopping, system performance can be significantly improved by more fully exploiting interference diversity, while maintaining frequency diversity, which is already associated with frequency hopping techniques. In order to more fully exploit interference diversity, each mobile station operating in a cell is allocated, in addition to a frequency hopping sequence, a frequency offset hopping sequence such that each mobile station hops from one frequency to the next frequency as a function of the frequency hopping sequence and its allocated frequency offset hopping sequence. This technique is readily applicable to increase both intercell and intracell interference diversity in unsynchronized or synchronizhed cells.

摘要： Based on a first radio technology, a V2X communication device (41, 42, 43) receives service information (402, 403, 404) in a first frequency spectrum. The service information indicates availability of at least one V2X communication service in a second frequency spectrum. The at least one V2X communication service in the second frequency spectrum is based on a second radio technology which is different from the first radio technology. Based on the received service information (402, 403, 404), the V2X communication device (41, 42, 43) controls utilization of one or more V2X communication services by the V2X communication device (41, 42, 43).

摘要： Method and arrangement for use in a node in a first system associated with a first frequency band for radio communication, for avoiding or reducing interference in a second frequency band associated with a second system, which second frequency band is adjacent to the first frequency band. The method comprises detecting activity of the second system in the second frequency band and determining characteristics of the second system current activity in the second frequency band. The method further comprises adjusting at least one parameter related to radio communication, based on said characteristics, such that interference to the second frequency band, from radio communication associated with the node, is adapted to the second system activity in said second frequency band.
