Abstract: 598903 A method implemented by a user terminal (100) for transmitting control information to a base station in a mobile communication network and the user terminal (100) are disclosed. The user terminal comprises a receiver (116) to receive downlink transmissions from a base station (20); a transmitter (112) to transmit control information associated with the downlink transmission to a base station (20); and a controller (122) to select radio resources for transmission of control information associated with the downlink transmissions. The controller is configured to select a first set of radio resources on an uplink component carrier if an assignment of a first downlink component carrier for the downlink transmission is received; and select a second set of radio resources on the uplink component carrier if an assignment of a second downlink component carrier or multiple downlink component carriers for the downlink transmission is received. The resources in the second set are additional radio resources as compared to the resources in the first set. A method implemented by a base station (20) of receiving control information from a user terminal in a mobile communication network and the base station (20) are disclosed. The base station (20) comprises a transmitter (24) to transmit user data on one or more downlink component carriers to a user terminal (100); and a controller (34) to schedule downlink transmissions to the user terminal (100). The downlink controller is configured to schedule downlink transmissions to a user terminal (100) on one or more downlink component carriers. If the user terminal (100) is scheduled to receive downlink transmissions on a first single downlink component carrier, the downlink controller receives control information associated with the downlink transmissions to the user terminal (100) on a first set of radio resources on a uplink primary component carrier associated with the first downlink component carrier; and if the user terminal (100) is scheduled to receive downlink transmissions on a second single downlink component carrier or multiple downlink component carriers, the downlink controller receives control information associated with the downlink transmissions to the user terminal (100) on a second set of radio resources on the uplink primary component carrier. The resources in the second set are additional radio resources as compared to the resources in the first set.

Abstract: 596765 Disclosed is a method in a base station for determining an uplink transmission timing correction for communication in a telecommunication system in which aggregation of component carrier (33, 34) is applied. A signal is received on a selected uplink component carrier (33, 34) from user equipment (30), and an arrival time of the received signal is measured. A timing correction of the uplink transmission timing is then determined based on the measured arrival time. A determination is made as to which of the uplink component carriers (33, 34) used by the user equipment (30) the determined timing correction is valid. This timing correction and information on which of the uplink component carriers (33, 34) the timing correction is valid for is then sent to the user equipment (30).

Abstract: The present invention provides a unified, rank independent mapping between antenna ports and group/code pairs. Each antenna port is uniquely associated with one code division multiplexing (CDM) group and one orthogonal cover code (OCC). The mapping between antenna ports and group/code pairs is chosen such that, for a given antenna port, the CDM group and OCC will be the same for every transmission rank.

Abstract: Embodiments herein relate to a method in a user equipment (10) for transmitting uplink control information in time slots in a subframe over a radio channel to a radio base station. The radio channel is arranged to carry uplink control information and the user equipment and radio base station are comprised in a radio communications network. The uplink control information is comprised in a block of bits. The user equipment maps the block of bits to a sequence of complex valued modulation symbols. The user equipment also block spreads the sequence of complex valued modulation symbols across Discrete Fourier Transform Spread - Orthogonal Frequency Division Multiplexing (DFTS-OFDM) symbols. This is performed by applying a spreading sequence to the sequence of complex valued modulation symbols, to achieve a block spread sequence of complex valued modulation symbols. The user equipment further transforms the block-spread sequence of complex valued modulation symbols per DFTS-OFDM symbol. This is performed by applying a matrix that depends on a DFTS- OFDM symbol index and/or slot index to the block-spread sequence of complex valued modulation symbols. The user equipment also transmits the block spread sequence of complex valued modulation symbols that has been transformed over the radio channel to the radio base station.
