摘要： Emergency call handling may, in the near future, require terminal unit location information to be provided to emergency service centers. Independent or quasi-independent systems, sometimes referred to as adjunct systems, can be provided to monitor remote unit transmissions and derive location information for mobile units making emergency access therefrom. Techniques for determining which channels each adjunct receive shall monitor are described herein, as well as specific monitoring techniques. Moreover, the adjunct system can use the received information to provide a second speech path to an emergency service center.

摘要： Emergency call handling may, in the near future, require terminal unit location information to be provided to emergency service centers. Exemplary embodiments of the present invention provide improved techniques for using a system of monitoring or adjunct stations to provide this location information to the emergency service centers. For example, received signal strength measurements in conjunction with path loss models, alone or in conjunction with either time of arrival (TOA) or time difference of arrival (TDOA) techniques can be selectively used to process received signals and provide location information. Techniques for improving timing estimates are also disclosed.

摘要： Method and apparatuses taught herein enable link adaptation feedback to be determined in advance for future transmit intervals, based on one or more data sending units sending indications of future transmit resource allocations, and receiving corresponding link adaptation feedback from data receiving units. Knowledge of the future transmit resource allocations enable individual data sending units to predict interference conditions for the future transmit interval, and thereby compute link adaptation feedback that takes advantage of low-interference conditions. Individual data sending units receive link adaptation feedback for the future transmit interval from the data receiving units they are supporting, and make corresponding link adaptations for the future transmit interval. Such operations are, in one or more embodiments, carried out in a Wideband Code Division Multiple Access (WCDMA), Long Term Evolution LTE), or WiMAX network, wherein the data sending units comprise radio base stations, and the data receiving units comprise wireless communication devices.

摘要： Code words are assigned to subscriber stations or groups of subscriber stations in a communication network for a quick paging mechanism in which the assigned code words are transmitted as quick paging signals over unused frequency resources to signal the subscriber stations. Subsets of multiple code words from a set of code words can be assigned to respective paging groups, and overlapping subsets can be assigned to multiple paging groups. This enables a single code word to be used to address either a single paging group or multiple paging groups.

摘要： A base station in an OFDMA system which determines a modulation and coding scheme to use for a packet of a certain size to be transmitted by a Mobile Station. The base station schedules transmissions by mobile stations and transmits packets. The base station includes a processing unit which determines a number of time-frequency resources required to transmit the packet for a modulation and coding scheme, determines an SINR based on the number of time-frequency resources used and available power at the mobile station, determines a transmission rate as a ratio of the packet size transmitted to the number of time-frequency resources used, sets a rate to zero if the determined SINR is lower than a threshold SINR required for the modulation and coding scheme, and selects the modulation and coding scheme with a highest transmission rate. The base station includes a memory storing modulation and coding schemes.

摘要： A receiver uses knowledge of pilot symbols transmitted by a neighboring sector to reduce interference in a received data symbol. The received data symbol is transmitted on one or more data subcarriers in a first sector. Overlapping pilot symbols transmitted on overlapping pilot carriers in a second sector are determined and used to generate channel estimates for the overlapping pilot carriers. The overlapping pilot symbols and pilot channel estimates are then used to reduce interference in the received data symbol.

摘要： A radio access network (RAN) (20) comprise a base station (28) and a wireless terminal (30). The base station 28 comprises a transceiver (38) and a frame handler (40), the wireless terminal (30) comprises a transceiver (48) and a wireless terminal frame handler (50). The frame handlers (40, 50) handle a enhanced frame F having enhanced frame structure. At least a downlink portion of the frame is formatted and handled in a manner whereby the frame can be perceived as a first format type of frame if the wireless terminal is a first type of wireless terminal and perceived as an enhanced or second format type of frame if the wireless terminal is a second type of wireless terminal. The frame handler configures the frame as plural subframes, each subframe having a downlink burst followed by an uplink burst. The frame is preferably configured to afford the second type of wireless terminal sufficient time to develop an acknowledgement for a message transmitted in a downlink burst, the acknowledgement being sent to the base station in an uplink burst which is within one frame length of the message.
