Abstract:
A network node (10) communicates with user equipments, UEs, in a cell served by the network node. The network node receives measurement reports from its UEs and obtains therefrom statistics (S 1 ). The network node receives an interference overload indicator, IOI, from a neighboring network node having a neighboring cell (S2) that may prompt making the determination. The network node uses the statistics to determine whether transmissions in the cell are or will be a likely cause of interference to the neighboring cell (S3). The network node then determines whether to take action with respect to one or more of the UEs based on the determination of whether transmissions in the cell are or will be a likely cause of interference to the neighboring cell (S4).
Abstract:
Systems and methods for providing efficient utilization of spectrum in a cellular communication network that applies Almost Blank Subframes (ABSs) are disclosed. In general, the network includes an access node that applies ABSs in the downlink. In one embodiment, the access node identifies UEs for which transmissions are to be scheduled for the uplink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs and subframes in the uplink that correspond to at least some of the ABSs in the downlink. In another embodiment, the access node identifies UEs for which transmissions are to be scheduled for the downlink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs for the downlink and at least a subset of the ABSs in the downlink.
Abstract:
A network node (10) communicates with user equipments, UEs, in a cell served by the network node. The network node receives measurement reports from, scheduled UEs (S1) and determines, based on the measurement reports, a number of neighboring cells that scheduled future transmissions by the scheduled UEs are likely to interfere with (S2). An interference indicator for each of the number of neighboring cells likely to be interfered with is determined (S3), and the network node sends the interference indicator to one or more neighbor network nodes serving one of the number of neighboring cells likely to be interfered with (S4).
Abstract:
A communications network (20) comprises a network coding node (24) and a network decoding node (26). A method of operating a communications network (20) comprises, at the network coding node (24), performing multi-domain network coding upon a first signal and a second signal to obtain a network coded signal. The first signal is modulated by a first modulation scheme and the second signal is modulated by a second modulation scheme. At least one of the first signal and the second signal includes information in a phase domain and information in an amplitude domain. The method further comprises transmitting the network coded signal over a link to a receiver (26) and performing multi-domain network decoding of the network coded signal as detected at the receiver (26) to obtain the second signal, the receiver knowing and using the first signal for the multi-domain network decoding.
Abstract:
Se describen los sistemas y métodos para proporcionar utilización eficiente del espectro en una red celular de comunicaciones que aplica Subtramas casi en blanco (Subtramas casi en blanco o vacías, ABS). En general, la red consiste en un nodo de acceso que aplica las ABS en el enlace descendente. En una modalidad, el nodo de acceso identifica los UE (equipos de usuario) para los cuales han de programarse las transmisiones para el enlace ascendente utilizando un esquema de programación que no requiere información de control para cada subtrama. El nodo de acceso entonces alinea en el tiempo instantes de programación de los UE y las subtramas en el enlace ascendente que corresponden con al menos algunas de las ABS del enlace descendente. En otra modalidad, el nodo de acceso identifica los UE para los cuales las transmisiones tienen que ser programadas para el enlace descendente utilizando un esquema de programación que no requiere información de control para cada subtrama. El nodo de acceso entonces alinea en el tiempo instantes de programación de los UE para el enlace descendente y al menos una subserie de las ABS en el enlace descendente.
