摘要： Aspects of this invention provide a MC wireless network, and a method, to allocate at least one carrier to a mobile station. The method includes making an initial carrier allocation of M carrier(s) to the mobile station, where M is less than or equal to a total number of carriers N in the MC wireless network; and subsequently re-allocating carriers to the mobile station, based on at least one criterion, by at least one of changing the value of M and moving the mobile station to at least one different carrier. A mobile station that is operable in the MC wireless network for dynamically changing its carrier allocations is also provided.

摘要： Apparatus, and an associated method, for forming a space-generated multilevel coding scheme for a radio communication system. Two or more modulators are positioned at a sending station (12). The modulators modulate, pursuant to separate modulation schemes, data that is to be communicated by the sending station (12). The modulation schemes are lower-order modulation schemes. The modulated data (16) is communicated to a receiving station (14), and detected at a least single receive antenna (76). The modulated symbols formed by the separate modulators are superimposed theretogether and form symbols of a higher order modulation scheme.

摘要： A prospective relay station sends a report indicative of radio resource sets/preamble sequences used by its neighbors. Where the reported radio resource sets comprise less than all available radio resource sets, a radio resource set that is not indicated in the report is assigned; else where the reported radio resource sets comprise all available radio resource sets, a resource set indicated in the report is assigned. A message is sent to the prospective relay station indicates the assigned radio resource set and an identifier for use as an enabled relay station. The message may include signal strength and IDs. Apparatus, methods and computer programs are detailed for both a base station and the relay node. Radio resource set re-assignment, managed mode relay operations (where the base station schedules traffic among relays using the same radio resource set), and power control of relays and associated mobile stations are also described.

摘要： A method includes selecting one of a plurality of transmitter systems used to transmit data. Each transmitter system corresponds to one of a plurality of subbands. Each subband has a bandwidth and at least two of the subbands have different bandwidths. A physical layer technology is common to and used by each transmitter system to transmit on a respective subband. The selected transmitter system transmits the data. An apparatus includes a plurality of transmitter systems, each corresponding to one of a plurality of subbands. Each subband has a bandwidth and at least two of the subbands have different bandwidths. A physical layer technology is common to and used by each transmitter system to transmit on a respective subband. A controller is operable to select one of the transmitter systems to use to transmit data, and is operable to cause the selected transmitter system to transmit the data.

摘要： Methods for use in multi-hop relay networks are described. One method includes receiving a first message from a first relay station requesting a temporary suspension of communication between the first relay station and one or more user equipment. In response to receiving the first message, a second message is transmitted to the one or more user equipment. The second message includes instructions to the user equipment to temporarily suspend communication with the first relay station at a specific time. A third message is transmitted to the first relay station. A scanning operation is performed at the specified time in response to receiving the third message. A second method for use in multi-hop relay networks is also described. The second method includes transmitting a neighbor information message. The neighbor information message includes a relay zone offset indicating the start of a station in a frame structure. Several apparatus are also described.

摘要： Apparatus, and an associated method, for facilitating communication of encoded data, formed of a systematic part and a non-systematic part, in a radio communication system. Systematic parts of the encoded data are assigned by an assignor to transmit antennas that are associated with communication channels exhibiting better, or best, communication quality levels. Determinations are made of communication conditions to rank the transmit antennas, thereby permit appropriate assignments of the encoded data to transmit antennas. Feedback is provided by the receiver that receives the transmitted data. The feedback information includes, or is formed responsive to, detections and other measurements at the receivers.
