摘要： 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 uplink component carrier 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 the 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.

摘要： The present invention relates to a method for generating, in a multiple access communication system, two-dimensional pilot signal patterns for propagation channel estimation in time and frequency, with equidistant sampling. The method includes the steps of: generating a generic pilot pattern that covers completely a first dimension and covers partially a second dimension, within a segment of the second dimension where the propagation channel is considered to have a constant value, and performing periodical duplication of the generic pilot pattern along the second dimension, where the duplication interval of the generic pilot pattern is equal to the required sampling interval in the second dimension. The invention also relates to a transmitter and a receiver of a multiple access communication system, such a multiple access communication system and a radio multiple access communication system.

摘要： A method in a Central Node (CN), a method in a Remote Node (CN), and a method in a wireless communication system for allocating reference signals are to be used for uplink transmission. According to one aspect of the invention reference signals are allocated with a method comprising the steps of: determining in a CN a number of reference signals N to be used for uplink transmission by a Remote Node RN; indicating to the RN the number of reference signals N to be used for uplink transmission by the RN; configuring an uplink transmission by the RN with at most the number of reference signals N; and performing by the RN the uplink transmission with at most the number of reference signals N on transmit antennas comprised in the RN. A CN and a RN relating to the methods are provided.
