    摘要: The invention relates to a method of estimating a downlink channel in a radio system, and to a radio system. The method includes transmitting a common pilot signal and a user-specific pilot signal, of which channel estimates are formed. A channel estimate for the user-specific channel that has transmitted the user-specific pilot signal is formed of said channel estimates by selecting an appropriate scaling factor. The quality of the user-specific channel estimation and thus also the performance of the radio system are improved by the invention.

    摘要: 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 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.

    摘要: From the network perspective, an uplink resource allocation (PDCCH) is sent that grants an uplink resource to a plurality of user equipments UEs, and the allocation has an indication of a cyclic shift CS for each of the plurality of UEs. The granted uplink resource is mapped to a downlink resource (PHICH) in dependence on the indicated CS for each of the plurality of UEs. The mapping is such that for a predetermined number of UEs being allocated a same uplink resource in a single MU-MIMO uplink resource allocation grant, each pair of said predetermined number of UEs which map to an adjacent downlink resource exhibit an optimized CS relative to one another. The network sends to each of the respective plurality of UEs on the respective mapped downlink resource an indication (ACK/NACK) about data received (on a PUSCH). Apparatus, method, and computer programs for network and UE side implementations are detailed.

    摘要: 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.

    摘要: 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.
