摘要： A method for transmitting information representative of a quality of a propagation channel between at least two devices of telecommunication network, the said method comprises a step of deriving a first channel quality indicator, a step of deriving a second channel quality indicator. This step is realized by using a look-up table associated modulation scheme and/or transport block size and/or signal to interference plus noise ratio with target error rate and by comparing an actual error rate with the target error rate. The method also comprises a step of transmitting the first and/or second channel quality indicator.

摘要： A wireless telecommunications network method and wireless telecommunications network node are disclosed. The method comprises providing a plurality of codebooks, each codebook identifying a phase shift to be applied to each signal to be transmitted by each of a plurality of antenna elements arranged in a plurality of pairs, each pair of antenna elements being spaced apart by a distance greater than a half wavelength of a carrier frequency, each codebook identifying a phase shift to be applied to each signal to generate a plurality of beams, each of which has a different angle of departure. In this way, a codebook is provided which enables different beams to be generated concurrently, each with a different angle of departure. This enables the channel conditions at the receiver to be improved using these different codebooks since beams are generated with the different angles of departure in order to better suit the different conditions experienced by the different beams.

摘要： A method of facilitating coordinated multipoint downlink transmissions by base stations, a base station and a computer program product are disclosed. The method comprises: transmitting a message between the base stations, the message indicating a utilisation associated with at least one precoder for the downlink transmissions by at least one of the base stations. Providing an indication of the utilization provides a framework to significantly improve the efficiency of transmissions between base stations and facilitate the coordination of multipoint downlink transmissions since only information about the utilization of particular precoders needs to be sent which avoids the need to transmit the precoders themselves, thereby reducing the quantity of data to be transmitted.

摘要： A method of configuring user equipment in a wireless communication network to operate to receive a transmission on one or more component carriers or a dynamically changing coordinated multipoint transmission from one or more transmission points in the network, a computer program product and network control node operable to perform that method. The method comprises: determining, for the user equipment, a set of two or more transmission points from which the user equipment may receive a transmission and allocating them to a coordinated multipoint transmission measurement set associated with the user equipment; determining, for the user equipment, a set of component carriers and associated transmission points in the multipoint transmission measurement set from which the user equipment may receive a transmission; allocating a set of modes of operation and component carriers associated with transmission points in the coordinated multipoint transmission measurement set for communication with the user equipment; associating a codepoint to each mode in the allocated set of modes of operation of the set of transmission points to form a codebook; and informing the user equipment of the codebook. Aspects and embodiments allow coordinated multipoint transmission schemes to be supported simultaneously with carrier aggregation techniques within a network and there is no need to define new bits for inclusion into the downlink control information message format.

摘要： A wireless telecommunications method, a computer program product and network nodes are disclosed. The wireless telecommunications network node method comprises on a failure to establish a connection after initiating a RACH procedure, repeatedly transmitting a RACH preamble signature using a defined set of resource blocks of an uplink channel. In this way, when a conventional RACH procedure fails to establish a connection with the network, a modified RACH procedure is instead initiated. This modified RACH procedure transmits a RACH preamble signature repeatedly using a repeating set of resource blocks which are repeatedly allocated from the uplink channel. This enables the RACH preamble signature to be repeatedly transmitted so that the energy from these repeated transmissions may be combined by the network in order to detect the presence of the RACH preamble signature transmitted by network nodes in a poor coverage area such as, for example, an MTC device located in a basement.

摘要： A method of configuring user equipment in a wireless communication network to operate to receive a dynamically changing coordinated multipoint transmission from one or more transmission point in said network, a computer program product and network control node operable to perform that method. The method comprises: determining, for the user equipment, a set of two or more transmission points from which the user equipment may receive a transmission and allocating them to a coordinated multipoint transmission measurement set associated with the user equipment; allocating a set of modes of operation of the transmission points in the coordinated multipoint transmission measurement set for communication with the user equipment; associating a codepoint to each mode in the allocated set of modes of operation of the set of transmission points to form a codebook; and informing the user equipment of the codebook. Aspects and embodiments described recognise that without significantly increasing the number of bits required in a downlink control information message, dynamic switching among some preselected or preconfigured coordinated multipoint transmission schemes can be efficiently supported within a network. The configuration of code points interpreted by user equipment may be set on a user equipment by user equipment basis and can be preconfigured by RRC signalling semi-statically.
