Abstract: An access point for a wireless wide area network can allocate two or more fundamental channels among wireless devices. In various implementations, the fundamental traffic channels may be for use with incompatible versions of the same air interface protocol (e.g., the 1xRTT and EV-DO versions of code division multiple access (“CDMA)). The access point may additionally have a reserved bandwidth that it can dynamically allocate to wireless devices to supplement the bandwidth allocated to them on the fundamental channels. For example, when sending or receiving large bursts of data, the access point can allocate additional bandwidth to the wireless devices, and after transmission of the large bursts of data, the access point can release the additionally allocated bandwidth.

Abstract: Assigning CDMA channel codes in a multiple beam zone sector such that they may be reused within the same sector. In an exemplary embodiment, the method includes configuring directional antennas in a cell sector to provide multiple beam zones in a cell sector and assigning channel codes for use within the beam zones such that each channel code is assigned for use in only one beam zone of any set of three consecutive beam zones in the cell sector. The reassignment is preferable conditioned upon the mobility status of the user. This effectively reduces the inter-user interference by ensuring at least two intervening beam zones are located between zones that are using the same channel codes, and that the second user is not mobile. The channel codes may be Walsh codes or quasi-orthogonal functions (QOFs).

Abstract: Presently disclosed is a method for reducing interference in a wireless distributed antenna systems. In an embodiment, interference is reduced by selectively placing a first wireless remote unit in a reduced signal interference mode. A controller sends a signal, such as a reverse link power-down signal, to the first remote unit after detecting less than a threshold incoming signal strength at the first remote unit. In an alternative embodiment, the controller requests that a given remote unit switch to the reduced signal interference mode when the controller is receiving signals from a mobile station through at least two different remote units.

Abstract: An access point for a wireless wide area network might receive a request from a wireless device to establish a session on the wireless wide area network. In response, the access point might establish a circuit switched uplink channel and a packet switched downlink channel for communications with the wireless device during the session. The access point might communicate with other wireless devices in this manner as well. Additionally, the access point might employ power control methods for the circuit switched uplink channels, and it might employ rate control methods for the packet switched downlink channels.

Abstract: The present invention provides a method and system for defining the mean opinion score (MOS) as a function of frame error rate (FER) and pilot signal strength. In an embodiment of the invention, an entity receives MOS scores that have been obtained using subjective tests for certain calls made within the network. Next, the entity receives FER and pilot signal strength samples that have been obtained for the calls for which MOS scores have been subjectively obtained. Finally, the entity calculates an equation for the MOS as a function of FER and pilot signal strength using a non-linear regression analysis.

Abstract: Methods and systems for selecting data rates are described in a wireless network. The distance between a client and a base station serving the client device is determined. Based on that distance, a minimum threshold data rate is selected such that a larger distance corresponds to a higher minimum threshold data rate and a smaller distance corresponds to a smaller minimum threshold data rate. An actual data rate, not less than the minimum threshold data rate, is then selected, and signals are transmitted between the client device and the base station at the actual data rate. The actual data rate may be increased if there exists unused available bandwidth in the network. Events such as a change in distance or a timer expiring may result in a recalculation of the minimum threshold data rate.

Abstract: The wireless coverage of a wireless telecommunications network is divided into a plurality of cells, and each cell is further divided into an alpha sector, a beta sector, and a gamma sector. The alpha sectors are provided with a first frequency assignment that includes a first frequency band and a second frequency band. The beta sectors are provided with a second frequency assignment that includes the first frequency band and a third frequency band. The gamma sectors are provided with a third frequency assignment that includes the first frequency band and a fourth frequency band. The second and third frequency bands partially overlap in frequency. The third and fourth frequency bands also partially overlap in frequency. By using overlapping frequency bands, the benefits of hybrid frequency reuse may be achieved in a more spectrally efficient manner.

Abstract: A wireless telecommunications network that uses a first frequency spectrum for wireless communications in a plurality of generally contiguous wireless coverage areas also has available a second frequency spectrum for wireless communications in a high-traffic wireless coverage area. Mobile stations in the high-traffic wireless coverage area are classified as either static or dynamic based on determinations of their speeds. The wireless telecommunications network uses the first frequency spectrum for wireless communications with dynamic mobile stations in the high-traffic wireless coverage area and uses the second frequency spectrum for wireless communications with static mobile station in the high-traffic wireless coverage area. The wireless telecommunications network may instruct the mobile stations in the high-traffic coverage area to use the appropriate frequency spectrum.

Abstract: A method and system for managing communications over an air interface of a wireless network. A base station may measure a level of interference over the air interface. Based on the level of interference, the base station may adjust a data rate and a transmit power of signals transmitted over the air interface.

Abstract: A wireless signal repeater will function to boost the strength of signals being communicated wirelessly between a base station and a mobile station. At the same time, however, the wireless signal repeater will read control channel messages transmitted by the base station and will obtain from the messages an indication of outside temperature and an indication of local time. The repeater will then display the outside temperature and local time information for viewing by a user. Advantageously, the repeater will thus become a more functional object in the eyes of the average lay-person, rather than functioning merely to boost wireless signal levels.

Abstract: A method and system for defining additional spread spectrum channels within a coverage area already served by an existing wireless network. A first spread spectrum channel may be defined by a first range of frequencies. A second spread spectrum channel may be defined by a second range of frequencies. A portion of the first range of frequencies may overlap with a portion of the second range of frequencies. The overlap may be such that the first spread spectrum channel and the second spread spectrum channel may carry signals that minimally interfere with each other.

Abstract: A method and system for controlling when a radio link layer connection to a wireless terminal is released. A packet data serving node (PDSN) may determine what type of communication is being exchanged with a wireless terminal. For example, the PDSN may determine that the type of communication with the wireless terminal is a push-to-talk session, a file transfer protocol session, a web browsing session, or an instant messaging session. Based on the type of communication, the PDSN may signal a base station. In response to the signal, the base station may control when a radio link layer connection to the wireless terminal is released. The base station may set an active-to-dormant timer with a period of time indicative of when the radio link layer connection to the wireless terminal is released.

Abstract: Increased data communication capacity in a sector of a CDMA wireless system using a combination of code division multiplexing and time division multiplexing. Adjacent subsectors may transmit carrier signals having the same frequency and using the same Walsh codes may be used by imposing a partial offset of the sector PN sequence.

Abstract: A method for dynamically directing a wireless repeater is provided. A repeater will include an antenna, a mobile station modem, a processor and data storage. The processor will cause the antenna to sweep over a coverage area, possibly through increments. At each increment, the antenna will receive signals and pass the signals to the MSM. The MSM will then apply a rake receiver to identify characteristics in the received signals, such as PN offsets and signal-to-noise ratios (EC/IO) for each PN offset, and the processor will record in the data storage the PN offsets and corresponding signal-to-noise ratios at that increment. Given this data, the processor will then instruct the antenna to move to the increment where the MSM detected the strongest signal-to-noise ratio. As a result, the antenna of the repeater will point at a base station that is likely to supply the signal with the highest signal-to-noise ratio.
