Interference control between different radio communication systems involving user equipments

A transmit power control system and method is provided which utilizes an efficient allocation of average output power of a multi-carrier power amplifier (MCPA), the average output power being a weighted average of the actual power over multiple time slots. Periodically, using the efficient allocation system and method, there will be short periods where the desired average output power will exceed the maximum tolerable power of the MCPA, P . These short periods in which the desired output power will exceed P are handled by a system and method which produces a reduced margin between the total power per time slot and P This reduced margin allows the MCPA to serve a larger number of users per time slot than conventional MCPAs. Alternatively, the MCPA can serve the same number of users as a conventional MCPA, but with higher demands on output power for each user and/or more efficient use of the MCPA's resources.

The invention relates to a method of performing handover in a mobile radio system. The mobile radio system performs quality measurements on signals transmitted ( ) between a mobile terminal and predetermined radio base stations. Handover is performed ( ) when some of the measured signal strengths exceeds the signal strength for the radio base station to which the mobile terminal for the moment is set up, added to a handover value. The handover value is dependent on measured signal strengths and neighboring cell relation values. The neighboring cell relation values depend on a probability for handover to be performed from one radio base station to another radio base station in the mobile radio system.

A wireless communications system, transmitter, receiver and method are provided that are capable of supporting incremental redundancy error handling schemes using available gross rate channels. More specifically, the transmitter includes a coding circuit for coding a digital data block and generating a mother code word, and a reordering circuit for reordering the mother code word and generating a reordered mother code word. The transmitter also includes a modulating circuit for modulating at least one subsequence each of which has a desired number of bits taken from the reordered mother code word to fill the available bandwidth of at least one available gross rate channel. The transmitter continues to forward the modulated subsequences to the receiver until the receiver successfully decodes the digital data block.

Telecommunications system and method for supporting an incremental redundancy error handling scheme using available gross rate channels

A method and system enables high data-rate users to be serviced even from within congested cells. If a user that is associated with an MS is located within a first cell that is too congested to provide the bandwidth requested by the user, all or a part of the information flow to/from the MS may be transceived from/to other nearby cells. For example, in a TDMA system, a user requiring three time slots per frame in order to aggregate sufficient bandwidth may be in communication with three different cells during each frame. The present invention may additionally be applied in the context of handoffs when, for example, an MS continues to be partially served by the previous cell before the new cell is able to service the high data-rate information flow. In another embodiment, the present invention may be implemented in a local wireless network environment in which multiple radio heads are controlled by a HUB.

The present invention provides a method by which users may be moved between time slots or between base stations in order to better utilize the MCPA output power resources. According to an exemplary embodiment of the present invention, the power of all transceivers served by a certain MCPA is compared to a threshold value X. The value X is at least related to the capability of the MCPA in terms of output power. If at no times (i.e., at all time slots), the sum of the output power exceeds the threshold value X, it is assumed that the MCPA can handle all simultaneous transmissions. If, during at least one time slot it is found that the required output power exceeds the capability of the serving MCPA, then a reallocation or load sharing algorithm is invoked. The reallocation algorithm searches for time slots to which a reallocation could be performed within the same base station or number of transceivers served by the MCPA. If no time slots can handle users from the time slot in which the MCPA limit is exceeded, then a load sharing algorithm is activated and one starts to look for transmission resources in transceivers served by other MCPAs, e.g., other cells. A number of alternative embodiments of the invention is described, which relates to the way in which the reallocation or load sharing is performed. By reallocating or moving users of a particular kind, e.g., single slot users, and avoiding reallocation of users of other particular kinds, the load sharing and reallocation are further improved.

In a mobile telecommunication system the transmission quality is dependent on a wide range of radio conditions. A method for extracting a useful estimation of the radio environment of a mobile station in communication in order to predict how the radio conditions will change in the near future for a considered mobile station in the near future. A measurement report is sent from the mobile station to the base station. The quality measure in the measurement report is filtered over the area by a smoothing filter ( ), and then processed through an updating filter ( ) resulting in a time varying map ( ). Several maps are classified ( ). Classified data are grouped ( ) resulting in the final map, which is stored in a database ( ). The final map may be used to enhance the performance of radio network algorithms.
