Abstract: A method and apparatus is provided for reducing interference in a radio communication link from a central site (230) to a mobile unit (228) in a cellular communication system. The central site (230) includes a first (202) and a second (216) antenna which serve the geographic region (214) in which the mobile unit (228) is located. The radio communication link may be provided by communicating a signal in a first radio communication channel between the first central site antenna (202) and the mobile unit (228). Similarly, the radio communication link may be provided by communicating a signal in a second radio communication channel between the second central site antenna (216) and the mobile unit (228). A measure of interference in the frist radio communication channel providing the radio communication link is determined. The radio communication link is switched, in response to the measure of interference being above a predetermined threshold, from the first to the second radio communication channel.

Abstract: Subscriber power levels are adjusted to enhance interference cancellation in a DS-CDMA communication system. A base-station (503) of the communication system receives signals from a plurality of subscribers (509-512) and evaluates each signal. Based on the evaluation, particular subscribers are commanded to control their power levels such that different predetermined targets for the particular subscribers are maintained. The predetermined targets include, but are not limited to, received power, frame erasure rate, bit error rate and signal quality. The resulting power levels received at the base-station (503) are substantially different, which is beneficially employed to enhance interference cancellation in the DS-CDMA communication system.

Abstract: A method and apparatus is provided for dynamic distribution of a communication channel load in a sectorized cellular radio communication system. The channel load is distributed by narrowing a first sector antenna beamwidth of an overloaded sector of a cell site and widening a second sector antenna beamwidth of an adjacent sector of the cell site and subsequently handing off subscriber units previously in the first sector antenna beamwidth. Alternatively, channel load is distributed by reducing power of a sector or omni-directional antenna which is adjacent to an overloaded antenna, if the channel from an overloaded antenna to an antenna of a subscriber unit is overloaded due to interference. Subsequent to the occurrence of the channel interference condition, subscriber units are handed off to the particular antenna which is best able to service the subscriber units.

Abstract: The invention relates to a system for allocating communication channels to communication units. A communication system comprises a communication channel allocator (207) that may allocate a communication channel to a first communication unit (205) for speech services. A speech interval controller (209) allocates the communication channel to a second communication unit (225) during a speech pause of the first communication unit (205). Also, a time interval allocator (211) allocates time intervals of the communication channels for transmission of an activity indication from the first communication unit (205). In response to receiving an activity indication in an activity indication time interval, a time slot controller (206) reallocates the communication channel to the first communication unit (205). The invention is particularly applicable to cellular communication systems such as GSM based communication systems.

Abstract: A base station (140) and a method (400) are described for providing transmit diversity. The base station generates a first signal based on a first data stream with a first pilot and a second data stream with a second pilot. The first signal includes the first and second pilots, which first pilot and second pilot are respectively based on a first orthogonal code and a second orthogonal code. The base station generates a second signal based on the first data stream with the first pilot and the second data stream with the second pilot such that the second signal including the first and second pilots is diverse relative to the first signal. Further, the base station phase-shift modulates the first signal to produce a phase-shift modulated signal. The base station transmits the phase-shift modulated signal via a first antenna (210) and the second signal via a second antenna (230).

Abstract: A communication unit (200) for use in a communication system is provided which includes a hopping mechanism (114, 144) which hops communication frames over a plurality of carrier frequencies according to a predetermined hopping pattern. At least one of the communication frames preferably includes a synchronization channel time slot having data bits from which the predetermined hopping pattern may be derived. In addition, a communication unit (100) is provided which includes a signal acquisition mechanism (142) for initially acquiring a predetermined hopping pattern that specifies the sequence over which hop frames are hopped over a plurality of carrier frequencies. Also, this communication unit (100) includes a hopping mechanism (134, 144) for hopping receiving frequency according to the predetermined hopping pattern such that a control channel may be detected. In an alternative embodiment, either communication unit may derive the predetermined hopping pattern from detected global position satellite information (149).

Abstract: The invention relates to a system for allocating communication channels to communication units. A base station (201) comprises a communication channel allocator (215) that may allocate a communication channel to a first communication unit (205) for e.g. speech services. A speech interval controller (217) allocates the communication channel to a second communication unit (207) during a pause of the first communication unit (205). A speech detector (229) of the first communication unit (205) detects that speech is resumed and accordingly transmits a predetermined access message to the base station (201). The predetermined access message is common for all communication units of a cell and provides for reliable detection in the presence of transmissions from the second communication unit (207). In response to receiving an access message, a time slot controller (213) reallocates the communication channel to the first communication unit (205). The invention is particularly applicable to cellular communication systems such as GSM/EDGE based communication systems.
