摘要： A solution for optimizing beamforming configurations and transmit power allocation configurations in a telecommunication system comprising a base station and a plurality of user entities is provided. The base station and the user entities are capable of multiple-input multiple-output (MIMO) communications, i.e. capable of communicating through spatial subchannels. The base station calculates iteratively optimal beamforming configurations for the base station and for each user entity and transmit power allocation configurations for each spatial subchannel used in MIMO communications. The base station carries out the calculation on the basis of channel state information received from the user entities by utilizing the information on correlation of different spatial subchannels, i.e. interference between the subchannels, in order to update beamforming configurations and transmit power allocation configurations.

摘要： A receiver comprising a digital code tracking loop which receives an input of real and imaginary components of a received signal and in which these components are processed in different branches which each comprise a multiplier (12a-12d) and a filter (13a-13d) connected in series. To improve the characteristics of the code tracking loop in the receiver, each branch of the code tracking loop further comprises circuitry (33a-33d) for absolute-valuing the signal, the circuitry (33a-33d) being connected in series after the filters (13a-13d).

摘要： A method includes sending a message from a first cognitive radio apparatus to at least one second cognitive radio apparatus, the message being sent over a first communication channel and containing an advertisement of at least one second communication channel for use in sending data from the first cognitive radio apparatus to the at least one second cognitive radio apparatus. The method further includes receiving a reply from the at least one second cognitive radio apparatus over the first communication channel, where the reply contains one of an acceptance of one of the at least one second communication channels, a rejection of the at least one second communication channel and an advertisement of at least one third communication channel, or a rejection of the at least one second communication channel without an advertisement of at least one third communication channel. The method further includes transmitting the data from the first cognitive radio apparatus to the at least one second cognitive radio apparatus over an agreed upon one of the second or third channels.
