摘要： A system and method of cancelling downlink inter-channel interference between a first selected UE in one sector of a cell and a second selected UE in a second sector of said cell by using intra-eNB DL CoMP is described. UEs which are affected by ICI are identified in sectors which are adjacent to each other in the cell. A downlink CoMP operational set is formed for the identified UEs. Channel matrix blocks are estimated for the first and second selected UEs. The channel matrix blocks are representations of the channel characteristics between the first and second UE, in their respective sectors and the serving base station. The estimated channel matrix blocks are then loaded into a cross-sector channel block matrix. The inverse values of the channel matrix blocks are then calculated to form a sector specific cross-sector pre-coding matrix which is used to enable interference cancellation.

摘要： A radio user equipment (UE) mobility status is determined in a communications node. UE mobility status measurements associated with the UE communicating over a radio channel are performed. The UE mobility status corresponds to a degree of variation of the radio channel over time. Channel characteristics of the radio channel at a first time and at a second later time are determined. Based on the determined channel characteristics, a channel characteristic error metric is determined and compared to a predetermined threshold. The UE mobility status is determined based on one or more iterations of the threshold comparison.

摘要： Provided is an IP QoS management mechanism for modern wireless networks to guarantee delivery of IP services with the required quality through the networks to customers. A layered QoS management architecture is provided which performs the QoS control over the entire communication protocol stack of a wireless network. The architecture consists of two levels of IP QoS management with an adaptation interface between them. These different functional and adapting levels are called from top to bottom, Upper Layer QoS Management (ULQM), IP QoS adaptation (IQA), and Lower Layer QoS Management (LLQM).

摘要： The invention provides a signal power control method and apparatus for a wireless system to control the power level of a received signal transmitted over a radio link so as to counteract transmission impairments caused by environment variations and maintain the reliability of the radio link. The signal power control of this invention serves to control the transmit power used for transmission and adjust the position of the receiver dynamic range so that the received signal can always be optimally received. In a preferred embodiment, the invention is incorporated in a broadband wireless access (BWA) time division multiplex access (TDMA) system to maintain the reliability of an upstream radio link connecting a base transceiver station (BTS) with multiple customer premises equipment (CPE) units. In the preferred embodiment, power control messages are exchanged between the BTS and the CPE units based on the international telecommunications union (ITU) R112 local multipoint distribution service (LMSD) standard for effecting the signal power control of the present invention.
