Abstract: The invention relates to reducing interference in indoor cells in a wireless cellular communication network. Outdoor and indoor base stations operate at a common uplink carrier frequency. The indoor base station monitors an uplink inter-cell interference level, and, responsive to the uplink inter-cell interference level reaching a predetermined threshold level, synchronizes with an uplink transmission signal received from at least one potentially interfering user equipment which is connected to the outdoor base station but outside the downlink coverage area of the indoor base station. The interfering user equipment is commanded, via a downlink control channel of the outdoor base station, to lower the transmission power of the uplink transmission signal, and to thereby decrease the uplink inter-cell interference level on indoor base station.

Abstract: Systems and methods for providing an efficient mechanism for transmitting encoded downlink assignment index (DAI) and for signaling the ACK/NAK information corresponding to downlink grant allocations in an over the air radio telecommunications network with time division duplex (TDD) capability, where aggregation of component carriers (CCs) is used. Downlink control messages containing encoded DAI information are transmitted with downlink allocation grants. A receiver observes the encoded DAI and the downlink allocation grants and forms corresponding ACK/NAK signals. Method embodiments for forming the ACK/NAK signals for CC groups and frames or subframes are provided. The ACK/NAK signals are then encoded using method embodiments and transmitted over parallel channels for each CC group to the transmitter. By using method embodiments for selecting resources for use in the transmission, the last observed DL grant can be identified by the transmitter and the transmitter can detect an error at the receiver.

Abstract: According to an embodiment a user equipment UE transmits uplink control signals using one or more chunks of uplink frequency spectrum that contain a simultaneous uplink shared channel; and for the case where there is no simultaneous uplink shared channel available, the UE transmits uplink control signals using only a single chunk of uplink frequency spectrum. In various embodiments the control signals are ACK/NACK control signals transmitted on an uplink control channel, the uplink shared channel comprises a chunk-specific uplink control channel, and each chunk comprises a component carrier of a LTE-A system. Downlink assignment index bits may be included in a downlink grant to the UE which indicates how many chunks in total are allocated in a current downlink subframe. The UE can also use ACK/NACK control signal bundling over chunks in addition to either or both of chunk- specific ACK/NACK control signals or ACK/NAK control signal multiplexing.

Abstract: A method for controlling channel signaling between a UE and a wireless network access node is described. The method includes determining whether an examined sub-frame of a plurality of sub-frames in a first resource region is unused. The index of the examined sub-frame is a last index of the plurality of sub-frames allocated for use in a first channel. The plurality of sub-frames is organized in a reverse indexing manner such that a last indexed sub-frame is adjacent to a second resource region. The second resource region is allocated to a second channel. In response to determining that the w examined sub-frame is unused, the examined sub-frame is re-allocated for temporary use in the second channel. The method also includes providing an indication of the allocation. Apparatus and computer readable media are also described.
