摘要:
A system that enhances upon current stereo audio wireless transmission/reception solutions by converting stereo audio to monaural audio and adding remote control functionality configured to appear as audio thus eliminating the need for additional digital wireless channels or resources. Namely—Audio plus Remote Control System (ARCS).

A method is provided a wireless system for reliably transmitting context information in robust header compression at low signal energies. More particularly, the methodology of the invention provides an elongated virtual Transmission Time Interval (Super TTI) for the first few (in particular, the first) non-compressed packet (that includes upper layer headers) of a packet stream transmitted using ROHC compression. Improved reception reliability for the uncompressed packet, in particular to decode the headers, results by application to the Super TTI of a combination of TTI Bundling techniques, RLC segmentation and association with multiple HARQ processes and use of enough HARQ rounds.

A method is provided for determining an allowed delay budget for the air interface portion of a communications link, the communications link comprising one or more air interface portions and a network portion. In particular, the method of the invention operates in a wireless communication system comprising an air interface portion and a network portion, and includes (1) determining a network delay for calls in the system on a per-call basis; and (2) apportioning an air-link delay budget for ones of calls in the system so as to maintain approximately equal total delay for all calls.

摘要:
A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.
摘要:
A wireless endpoint employs frequency hopping for communicating signals in a wireless communications system. Over a time period T, the wireless endpoint performs pseudo-random selection of a frequency from a hopping set of N frequencies such that over at least a portion of the time period T, the frequency selection is constrained to less than the N frequencies.
摘要:
A method and apparatus for reducing the information error rate of a communication network. The apparatus comprises a selector device coupled to a Framer and to an Interleaver. The selector device is configured to receive system information and the Framer is configured to receive user information. The apparatus is coupled to equipment which operate the communication network based on system parameters. The apparatus and method of the present invention improve the coding and effectively increase the interleaving depth applied to user information thus reducing the information error rate of the communication network without having to alter or modify any of the system parameters.
摘要:
A method of determining a bias parameter for a heterogeneous network including a small cell, a macro cell, and one or more user equipment (UEs), the small cell being underlaid with respect to the macro cell, includes determining, at a base station of the small cell, a loading state of the macro cell; and setting, at the base station, the bias parameter based on the determined loading state. A method of determining a cell border window (CBW) for the small cell, the small cell being underlaid with respect to the macro cell, the small cell having a plurality of attached UEs which are divided into inner cell UEs and border cell UEs, includes determining, at the base station, a difference value based on utilization values of the inner cell UEs and the border cell UEs; and adjusting the CBW based on the difference value and a threshold value.
摘要:
A measurement radio system uses a measurement radio to scan active channels of a base station and produce operating information for the traffic radios servicing the active channels. The measurement radio can produce operating information, such as signal strength, bit error rate (BER), frame error rate (FER) and signal to interference ratio (C/I), which is used to determine whether to change the manner in which the traffic radio is servicing the active channel. For example, if the measurement radio can switch between different sets of antennas, the measurement radio can scan an active voice/data channel using a different set of antennas than the traffic radio is using to service the active channel and determine operating information related to the signal received over the active channel using the different set of antennas. The traffic radio can use the operating information to determine whether to hand off the active channel to the different set of antennas. The measurement radio can determine operating information, such as operating coefficients, parameters or settings, to change how the traffic radio services the active channel.
摘要:
A method for conveying information in a new format structure for a wireless communication system in which users convey information on a time slot basis. The new format structure is made compatible with the system's existing format by partitioning system time slots into subslots.
