    Abstract: In a method of operating a communication network (20) a time division duplex (TDD) frame (F) of information is communicated over a radio interface (32) between a wireless terminal (30) and a base station node (28). The method comprises the wireless terminal (30) receiving plural downlink (DL) sub frames of the frame and, in response thereto, configuring a Physical Uplink Control Channel (PUCCH) channel to comprise up to four acknowledgements by using only two PUCCH channel resources and using PUCCH format Ia or PUCCH format Ib. In an example embodiment a PUCCH channel resource is specified by a sequence utilized for transmission of at least part of the PUCCH channel and a cyclical shift applied to the sequence. The two sequences of the respective two PUCCH resources are orthogonal, and the cyclical shift of the two PUCCH resources can be in a frequency domain, a time domain, or both the frequency domain and the time domain.

    Abstract: The present invention relates to cellular radio communication and in particular to providing information on neighbour cells to enable terminals to perform neighbour cell measurements. In the prior art the terminal attempts to make neighbour cell measurements in a reference signal structure that is the same in the neighbour cell as in the cell the terminal camps in. The present invention is based on the insight that the reference signal structure may differ between neighbouring cell for example in the situation of an MBSFN area that is restricted to a region of all cells of a radio network, or in the situation of TDD mode being applied there may be different regions with different allocation of sub-frames for transmission in the uplink and downlink directions. The present invention solves the problem by broadcast information in a cell indicative of the reference signal structure in neighbour cells.

    Abstract: Un procedimiento de transmisión de enlace de bajada en una primera celda en una red que comprende una pluralidad de celdas organizadas en dos o más regiones de red de frecuencia única de transmisión de multidifusión, MBSFN, con respecto a una asignación de subtramas normales y de subtramas de tipo MBSFN, comprendiendo el procedimiento las etapas de: transmitir (S1) una primera señal de referencia, según una primera estructura física de señal de referencia para las subtramas normales, en el que la primera señal de referencia es portada por símbolos de OFDM predefinidos y por subportadoras predefinidas dentro de las subtramas normales según la primera estructura física de señal de referencia, en el que símbolos de OFDMpredefinidos que portan señales de referencia difieren entre la subtrama normal y la subtrama de tipo MBSFN, caracterizado por transmitir además (S2) información indicativa de una segunda estructura física de señal de referencia para portar una segunda señal de referencia en una celda vecina.
