Abstract: A method of estimating and compensating for Doppler frequency shifts includes providing an accurate reference device for generating an accurate reference frequency in a Doppler estimation and compensation (DEC) system, the DEC system being electrically connected to a user device. The DEC system receives one of a downlink signal from a base station and an uplink signal from the user device. The one of the downlink signal and the uplink signal is compared to the accurate reference frequency. An estimate of a Doppler frequency shift associated with the one of the downlink signal and the uplink signal is determined. An offset Doppler frequency shift of opposite sign as the Doppler frequency shift is added to the one of the downlink signal and uplink signal to provide a compensated signal. The compensated signal is transmitted to one of the base station and user device.

Abstract: Various embodiments of the present invention relate to wireless network management. One specific example relates to efficient radio frequency (RF) spectrum management involving multiple mobile vehicles, whereby a system and/or a method of the invention achieves greatly improved spectral efficiency in the assignment of frequency bands to communications channels between the vehicles and/or stationary ground stations. Other examples of the present invention provide systems and methods to analyze the RF emissions resulting from the motion of transmitters and/or receivers through airspace with the help of five-dimensional quanta of space (x, y, z), time and frequency to assign frequency bands to test plans (including previously-validated test plan(s) and/or to-be-validated test plan(s)). In one specific example, the analysis is directed to the assignment of frequency bands with and without reuse.

Abstract: Improved ranking and grouping techniques are disclosed for communication systems such as a multiple input multiple output system. For instance, techniques are disclosed for ranking and grouping users that are eligible for single-user and/or multiple-user transmissions. In one case, ranking and grouping are performed independently and, in another case, ranking and grouping are performed jointly.

Abstract: A method for implementation of HARQ between a transmitting node and a receiving node in a communication network is provided. HARQ processes may be selected from a list for instantiation according to a policy that may deviate from strict first-in, first-out processing of packets. The greater flexibility that this affords may lead to improved efficiency in the use of transmission resources.

Abstract: A wireless communication system (20) includes using multiple antennas (30, 32) for simultaneous transmissions to multiple mobile stations (24, 26). A distributed multiple antenna scheduling (DMAS) technique includes selecting a plurality of mobile stations for at least receiving simultaneous transmissions on at least one selected subcarrier from within a carrier bandwidth having orthogonal frequency division multiplexing (OFDM). In a disclosed example, a plurality of mobile stations are selected for each subcarrier within the carrier bandwidth. A disclosed example includes grouping subcarriers together into subsets to reduce computation complexity for determining which mobile stations to select for the simultaneous transmission.

Abstract: A wireless communication system (20) includes a wireless network (30) that selectively modifies an aggregation of voice over internet protocol wireless transmissions. In one example, a mobile station geometry provides an indication whether modification of the aggregation is desirable. For example, a mobile station with a better geometry allows for a higher level of aggregation. Another disclosed example includes determining a current cell load condition and increasing the amount of aggregation and the level of aggregation as cell load conditions increase. Another disclosed technique includes staggering the scheduling of aggregated packets to avoid delays at a scheduler. One or more of the disclosed techniques may be used to efficiently transmit voice over internet protocol communications.

Abstract: A wireless communication system (20) includes a wireless network (30) that selects between a dedicated communication channel and a shared communication channel for transmitting a real-time communication such as a voice over internet protocol (VoIP) communication. In one example, a radio network controller (40) portion of the wireless network (30) evaluates channel conditions of the available channels for purposes of selecting the channel for the transmission that will maintain or enhance efficiency of the network. In a disclosed example, the selection is made at the initiation of a call. In another disclosed example, the selected channel condition or conditions are periodically evaluated to determine whether switching during a call is desirable. In another example, both channel types are used simultaneously at least during a handoff where a switch is made from one channel type to the other.
