Abstract:
Uplink control information transmission method, and a network node and a UE implementing the method are disclosed. According to an embodiment of the invention, uplink control information is transmitted from a UE to a network node by defining a set including at least one of the of uplink component carriers being usable for carrier aggregation for the UE. For this set, a priority indication is assigned to each one of the at least one uplink component carrier included in the set. Then, if this set includes at least one uplink component carrier comprising an uplink shared channel, one of these at least one uplink component carrier comprising an uplink shared channel is selected for transmission of uplink control information in that uplink shared channel. Selection based on at least one of the at least one assigned priority indication, when selecting uplink component carrier, is disclosed.
Abstract:
A method can be used for facilitating a random access procedure between a first transceiver and a second transceiver within a cell. The first transceiver selects a signature sequence from a set of signature sequences, incorporates the signature sequence into a signal, and transmits the signal to the second transceiver. The set of signature sequences being obtained from a sequence with zero correlation zone.
Abstract:
A method is provided for arranging transmissions on a downlink carrier c, spanning a frequency range Fc, in a mobile radio communications system, wherein a bandwidth of Fc belongs to a set of predefined channel bandwidths in the communications system, and wherein the carrier c comprises a reference signal defined in the communications system. A configurable frequency range FRS comprising a set of time-frequency resources for comprising the reference signal of the carrier c is provided. Information associated with the configuration of the frequency range FRS is signaled to a receiver in the communications system, such that c can be deployed over a frequency range F smaller than Fc when the frequency range FRS is configured within F and any other transmissions on the carrier c are arranged to be within F.

Abstract:
The present invention relates to methods for concurrent transmission and reception of information symbols over time-frequency resource elements in a wireless communication system. According to the present invention coded bits interleaving is combined with symbol spreading using LDS signatures. Thereby, the performance of coded LDS transmissions can be substantially improved in wireless communication systems. Furthermore, the invention also relates to corresponding transmit device, receiver device, computer program, and computer program product.
Abstract:
The present invention relates to a method for allocating communication resources in a multi-user cellular communication system, wherein communication resources are divided in time periods and frequency sub-bands, wherein part of the communication resources are used for frequency-localized communication channels, and part of the communication resources are used for frequency distributed channels. The method further comprises the steps of: classifying part of the frequency sub-bands as frequency sub-bands carrying frequency-distributed channels, classifying the remaining part of the frequency sub-bands as frequency sub-bands carrying frequency-localized channels. The present invention also relates to a system, a transmitter and a communication system.

The present invention relates to a method in a network control node for transmission of control channel signals in a wireless communication system, the wireless communication system employing scheduling of physical resource blocks (PRBs) used for each new transmission of a control channel signal, wherein each control channel signal is related to one or more control channel elements (CCEs); the method comprising the steps of: removing user specific reference signals in associated physical resource blocks (PRBs) if the associated physical resource blocks (PRBs) comprises at least one control channel signal; inserting control channel signals in the associated physical resource blocks (PRBs); and transmitting the associated physical resource blocks (PRBs). Furthermore, the invention also relates to a computer program, a computer program product, and a network control node device thereof.
Abstract:
The invention concerns a method for precoding in an open loop transmission communications system, wherein the method includes precoding data at each of M REs with a precoding matrix, precoding each of DM-RSs with one column of a precoding matrix which is same as that used for precoding M data REs. The method is distinguished by using at least L≧2 different precoding matrices from a set of precoding matrices W to precode the M REs and the E allocated REs such that REs precoded with a first precoding matrix are interleaved with REs precoded with at least one additional, different precoding matrix and the number of used precoding matrices L is adapted to the transmission rank r and number N of available DM-RS. The invention further concerns a radio transmitter and a user equipment.
Abstract:
A quantity of antenna ports of a transmitting apparatus is signalled in a wireless communication system. The quantity of antenna ports of the transmitting apparatus is encoded into a first type information and a second type information. The first type information is transmitted on a physical broadcast channel (PBCH); and the second type information is transmitted on a physical downlink shared channel (PDSCH). The PDSCH is transmitted on at least one antenna port indicated by the first type information.
