摘要： Some embodiments of the present disclosure provide for signaling, by a transmit receive point, of information that allows a user equipment to perform an agile beam tracking procedure. The information may indicate a shift of direction for a transmit beam with respect to a reference beam direction. In addition to signaling a shift of direction for a transmit beam, aspects of the present application relate to a method of detecting, at the user equipment, beam misalignments. Conveniently, the beam misalignments may be detected in the absence of an estimate of location of the user equipment, in the absence of an estimate of location of the transmit receive point and in the absence of an estimate of a mobility pattern. Aspects of the present application also relate to a method of exploiting a transmit/receive beam pair direction of one transmit receive point to facilitate beam establishment and beam tracking for a second transmit receive point. Conveniently, aspects of the present application may be shown to reduce signaling overhead.

摘要： A method, system and apparatus are disclosed. According to one embodiment, a method implemented in a WD is provided. The WD is configured to communicate with a network node, and is further configured with at least a first and a second TCI state. The first TCI state is the currently active TCI state. The method comprises receiving (S1310) an indication from the network node to switch from the first TCI state to the second TCI state; determining (S1320)whether a condition for the switch from the first TCI state to the second TCI state is met; and in response to the received indication to switch, performing (S1330) the switch to the second TCI state when determining that the condition for the switch is met, and refraining from performing (S1340) the switch to the second TCI state otherwise.Publication:

摘要： An apparatus and method are disclosed for mitigating pointing errors resulting from satellite antennas. Reports are received from terminals in a beam hopping satellite communication system, and a pointing error associated with a satellite antenna is determined. The best beam for communicating with each terminal is selected based on the pointing error. A beam list containing the instantaneous traffic demand of terminals for each beam in the system is generated. An active beam set is then selected from the beam list for transmitting data during the next hop in the satellite communication system.

摘要： The present invention provides a method to protect wireless communication signals from being overheard/intercepted by malicious eavesdroppers. The method has three main steps: selection of the coordinating transmission points (TPs) for the user whose communication is to be secured, splitting of the data that is to be sent to the aforementioned user into N parts, where N is the number of TPs used and channel based manipulation of the transmitted signal to ensure that delay spread is less than guard duration.
