Abstract:
Disclosed are methods as well as wireless devices and radio network nodes for radio resource management (RRM) in inter-operator time-sharing of a frequency spectrum Fs. In one example embodiment, the same frequency spectrum Fs is allocated to each of a plurality of operators during different time periods such that the same frequency spectrum is shared among all of the plurality of operators.
Abstract:
The present invention relates to a method for sending reserved sub-carriers to a UE for the purpose of reducing peak to average power ratio (PAPR) of the transmitted signal to ensure sufficient quality of the modulated signal to achieve high data rate, including the steps of sending the information related to dynamic activation and deactivation of reserved sub-carriers on a common channel, which is readable for all UEs in idle and in connected mode; dynamically activating the transmission of the reserved sub- carriers in a cell when high modulation quality is to be maintained; dynamically deactivating the transmission of the reserved sub-carriers in a cell when high modulation quality is not required. The invention furthermore relates to a radio base station and a UE relating to said method.
Abstract:
A MIMO-capable base station allocates a maximum transmission power budget to each of its antennas. For serving each of one or more MIMO and non- MIMO users, one or more carriers are allocated. For each carrier, information about an amount of allocated MIMO and non-MIMO user resources associated with the carrier is used to derive coefficients. Each coefficient corresponds to a unique one of the antennas, and represents a proportion of a maximum power budget for the carrier. For each carrier, the coefficients and the maximum transmission power budget for the carrier are used to derive a maximum transmission power budget for each of the antennas. For each antenna, a total maximum transmission power budget for the antenna is derived by combining the derived maximum transmission power budgets of the carriers transmitted on the antenna. The total maximum power budget of the antenna should not exceed a limit for the antenna.
Abstract:
An interface, apparatus, and method are described for communication between a radio equipment control (REC) node and a radio equipment (RE) node in a radio base station that tranceives information over radio interface using multiple antenna carriers. The REC node is separate from and coupled to the RE node by a transmission link. Both control information and user information are generated for transmission over the transmission link from one of the REC node and the RE node to the other. Many advantageous interface features are described.
