Abstract: The present invention relates to a method, device and system for handling short data packets, such as speech packets, in a communications network, and in particular a wireless local area network. The present invention is based on collecting several data packets from several users active on the network in one data transmittal protocol packet, transmitting this protocol, and receiving the protocol wherein the each of the several data packets are addressed to specific destinations. This reduces the overhead/data ratio and thus increases the capacity of the network.

Abstract: 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.

Abstract: Method and system are disclosed for improving the channel quality in a packet data radio network. In each cell of the radio network the packet data is measured based on channel utilization and/or packet queue measurements. A power control algorithm uses the packet data load to determine a common or equal broadcast or transmitted power level for the channels in the cell. The common broadcast or transmitted power may subsequently be adjusted on an individual channel basis for channels that fall outside a predefined quality window.

Abstract: The present invention pertains to the field of methods and apparatuses relating to radio communication; and in particular to the part of this field that concerns cellular radio communication. The present invention addresses mainly the problem of improving reliability and communication quality in a cellular radio communication system (1). According to the invention, it is determined whether one of an uplink (25) or a downlink (25) of a radio channel (23) is subject to a Rayleigh fading dip. If it is determined that one of the uplink (25) or the downlink (27) is subject to a Rayleigh fading dip, it is then determined whether it is necessary to execute a countermeasure in order to avoid the negative influences of Rayleigh fading on the channel (23). The invention is not limited to improving conditions on one channel but may be employed to any number of channels used for communications in the cellular radio communication system (1).

Abstract: The present invention is a method and system for managing frequencies allocated to a cell within a cellular network to assign certain ones of those allocated frequencies for use by channel equipment within that cell. The method measures at least one quality metric for each of the allocated frequencies. At least one measured quality metric for the unassigned frequencies are compared against at least one quality metric for the assigned frequencies. An unassigned frequency is swapped for an assigned frequency based upon the comparison step. Additionally, a voting step is used to indicate that either the unassigned frequency or the assigned frequency has a higher signal quality for communication.

Abstract: Each base station in a cellular telephone system includes a signal strength measurement device operable to tune to and make signal strength measurements on not only the frequencies allocated to other cells, but also on its own allocated frequencies. Measurements are made by the device on those of its own frequencies having idle traffic channels to obtain an indication of injected uplink interference. An interference penalty is then assessed against the measured uplink interference for those frequencies having more than a threshold number of idle traffic channels. The adjusted measurements for the frequencies allocated to the cell are then sorted in relative order of idle traffic channel (adjusted) measured uplink interference from a least (adjusted) interfered frequency to a most (adjusted) interfered frequency. An idle traffic channel is then selected for assignment at either call set-up or hand-off from the least (adjusted) interfered frequency.

Abstract: Method performed by a first communication device (101) operating in a wireless communications network (100). The first communication device (101) obtains (301) a set of correspondences (400) associating: i) each set (? i ) of a plurality of sets of antenna weights (? 1 ? i ) having been sent by a third communication device (103) in response to having received a respective set (RSs i ) of a plurality of sets of radio signals (RSs 1 RSs i ) from a set of antenna ports in a second communication device (102), with ii) a respective direction of transmission (d i ) between the second communication device (102) and the third communication device (103). The respective direction is relative to an orientation (a i ) of the second communication device (102). The respective direction of transmission (d i ) is a selected direction of transmission (d i,ai ). The first communication device (101) then initiates (303) transmission of a new radio signal, based on the obtained set of correspondences (400).
