Abstract: A first User Equipment (UE), a second UE, a first Radio Network Node (RNN), and methods therein for controlling interference between transmissions in a first system and transmissions in a second system. The first system comprises the first UE and the first RNN serving the first UE. The second system comprises the second UE and a second RNN serving the second UE. The first system has a first priority in a first part of a shared spectrum and the second system has a second priority in the first part of the shared spectrum, wherein the first priority is higher than the second priority. The method in the first UE comprises transmitting a signal to a second RNN that is to perform a downlink transmission to the second UE, which signal is configured to control the transmission of the second RNN.

Abstract: A method of communicating control information in systems that support multiple modulation schemes for communicating voice or data and control information. To provide backward compatibility dedicated control channels use the modulation scheme used in current systems, for example GMSK modulation scheme. Traffic channels and associated control channels use linear modulation schemes that have the same symbol rate. The modulation scheme of the associated control channel uses a reduced signal set of the modulation scheme used for traffic channels. Also, an in-band signalling procedure is used to indicate to a receiving station the modulation type, channel coding and speech coding used for a transmitted burst.

Abstract: In a communication system, a link protocol for a transparent data between a mobile station and a base station is selected by pre-selecting from all possible combinations of available link protocols a set of pre-selected combinations of link protocols based on a predefined service requirement and at least one basic capability of the mobile or base stations. Then, the link protocol is selected from the pre-selected combinations of link protocols based on measurements of one or more link quality parameters and at least one variable restriction caused by instantaneous conditions in the communication system.

Abstract: A method of demodulating voice or data and control information in systems that support multiple modulation schemes modulates voice or data using a first linear modulation scheme, such as 16QAM modulation scheme, and modulates control information using a second linear modulation scheme, for example, QPSK modulation scheme, that has the same symbol rate as that of the first modulation scheme. The first linear modulation scheme has a higher modulation level than the second linear modulation scheme. Information modulated using the second linear modulation scheme, which uses a reduced signal set of the first linear modulation scheme, are demodulated using the same demodulator that is used for demodulating information modulated using the first linear modulation scheme. Also, in-band signalling information within a traffic channel, such as stealing flags, are modulated using the second modulation scheme.

Abstract: A method and system of adaptive channel allocation in a multi-carrier, multi-slot system is provided. In the method and system a subset of M channels is chosen from a larger set of N channels available for communications on a link. As communications take place on the link, signal quality (C/I) measurements on the channels of the subset of M channels and interference (I) measurements on the channels of the group of N channels are periodically performed. The C/I and I measurements are then used to reconfigure the subset of M channels to reduce co-channel interference on the link.

Abstract: Apparatus, and an associated method, controls operation of a mobile terminal operable in a communication system having two network portions. Selective permission of cell selection of communications between the two network portions better assures that the mobile terminal, when positioned in an area intended to be encompassed by one of the network portions, communicates with that network portion.

Abstract: A communication system supports multiple modulation schemes having differing symbol rates. The system supports two modulation schemes that have the same symbol rate and at least one modulation scheme that does not have the same symbol rate. For as long as communication can be carried out using the modulation schemes with the same symbol rate, the system avoids using the modulation scheme with different symbol rate, even if communication can be carried out using this scheme.

Abstract: A communication network, and associated method, permitting wireless communication with a mobile unit in an indoor environment. Transceivers are positioned at spaced-apart locations and are coupled to a centralized, control device. The transceivers include transmitter portions and wideband receiver portions. Uplink signals transmitted by a mobile unit are received by receiver portions of transceivers within the range of the uplink signal. Downlink signals are generated by at least two transmitter portions of at least two transceivers. The control device controls selection of which transmitter portions and which receiver portions of the plurality of transceivers are utilized to effectuate two-way communication with the mobile unit. Control signals can also be transmitted by the transmitter portions of all of the transceivers such that a mobile unit positioned anywhere within the area of the communication network receives the control signals.

Abstract: A method and apparatus for adaptively reconfiguring a neighbor cell list. For a selected cell of a cellular system, data associated with the selected cell and each of a plurality of neighboring base stations is collected. The collected data includes data on events indicative of the quality of handoffs from the selected cell to each of the neighboring base stations. The collected data also includes signal level measurements made on measurement channels of the neighboring base stations. A plurality of quality values, each associated with the selected cell and one of the neighboring cells, are then determined from the collected data. A neighbor cell list is then generated for the selected cell by determining the highest quality values, and placing the handoff measurement channels of the neighboring cells associated with the highest quality values in the neighbor cell list.

Abstract: Circuitry, and an associated method for a multi-user communication system, such as a cellular communication system. Additional communication is selectively permitted in the communication system through operation of the circuitry. Levels of communication quality of ongoing communication in the communication system are determined. When a request is made to admit additional communication, the additional communication is admitted only when the level of communication quality is better than a selected threshold.

Abstract: A method and system of adaptive channel allocation in a frequency division multiplexed system is provided. In the method and system a subset of M subcarriers is chosen from a larger set of N subcarriers available for communications on a link. As communications take place on the link, signal quality (C/I) measurements on the subcarriers of the subset of M subcarriers and interference (I) measurements on the subcarriers of the group of N subcarriers are periodically performed. The C/I and I measurements are then used to reconfigure the subset of M subcarriers to reduce co-channel interference on the link.

Abstract: A method and system for measuring signal level in a telecommunications system having a mobile assisted handoff (MAHO) feature. The method and system utilizes the MAHO feature to perform signal level measurements, at a mobile station, on channels other than handoff measurement channels on which signal level is measured for MAHO purposes. Use of the method and system reduces the effects of making additional measurements on the efficiency of the MAHO process. A system operator may obtain signal level measurements for various purposes other than MAHO without adversely effecting the MAHO process.
