摘要： The invention relates to a method in a first communication device of receiving control information over a radio channel from a second communication device. The first communication device receives a subframe over the radio channel, and determines whether the subframe is a downlink subframe with downlink assignment intended for the first communication device by reading data in the subframe. That being the case, the first communication device decodes data within the subframe, and determines whether any data packet being sent from the second communication device before the subframe has been missed by analysing an indicator associated to the subframe in the data. The indicator provides knowledge about previous downlink subframes with downlink assignment intended for the first communication device.

摘要： A method for scheduling resources for uplink transmissions in a radio access network includes each of a plurality of access points (APs) placing its resources to the disposition of other APs and transmitting a blocking signal if it does not allow other APs to use any of its resources. The method includes a user terminal (UT) listening for blocking signals and an AP scheduling the UT on the AP's own resources and/or on resources belonging to one or more other APs.

摘要： Embodiments herein include a method in a user equipment (UE) for transmitting uplink control information in time slots of a subframe over a radio channel to a radio base station. The uplink control information is comprised in a block of bits.The UE maps the block of bits to a sequence of complex valued modulation symbols. The UE block spreads the sequence 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 UE further transforms the block-spread sequence, 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. The UE also transmits the block spread sequence, as transformed, over the radio channel to the radio base station.

摘要： A communication device has a first transceiver that operates in a first communication system in the presence of a second transceiver that operates in a second communication system that is unrelated to the first communication system. A scheduler of packets for transmission by the first transceiver uses information about when the second communication system will be transmitting a signal that will interfere with reception by the first transceiver, and schedules data for which re-transmission is not essential in those time slots in which an implicit NACK is expected due to the second transceiver's operation.

摘要： Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

摘要： The present invention relates to methods and arrangements for improving the capabilities of an evolved Universal Terrestrial Radio Access Network, in particular for cases when more than one radio access network applying a time-division duplex transmission mode need to co-exist on a same carrier. The invention addresses further problems concerning an efficient allocation of uplink resources and resource allocation in a handover situation. The present invention assigns an attribute in form of a distinguishing value to the time slots used for the uplink and downlink transmission on said carrier such as to avoid scheduling of transmissions via a first radio access network in downlink or uplink time slots assigned to the second radio access network and to avoid scheduling of transmissions via the second radio access network in uplink time slots assigned for transmissions in the first radio access network.

摘要： The present invention relates to methods and a transmitter and a receiver for a mobile communication system. The basic idea of the present invention is to recursively derive from previous HARQ feedback the number of HARQ transmissions that is required to be able to decode the transmitted data successfully and to only transmit explicit HARQ feedback information if the decoding result differs from the derived result.

摘要： The present invention relates to a base station and a method in a mobile telecommunication network for allocating and de-allocating uplink base station processing resources to a mobile terminal. The base station are adapted to communicate to a mobile terminal on an uplink channel supporting macro-diversity, and the base station is adapted to be a non-serving base-station without control of the resource allocation to the mobile-terminal. The base station comprises means for predicting a likelihood of successful decoding of a future transmission, and means for allocating or de-allocating processing resources based on said prediction.
