    摘要: According to one aspect of the present disclosure, an apparatus of wireless communication is provided. The apparatus may include a radio. The radio may perform a joint estimation procedure to estimate a set of beam parameters for each of the plurality of beams. The radio may estimate, based on the set of beam parameters, a plurality of amplitudes associated with the plurality of beams. The radio may identify a maximum amplitude of the plurality of amplitudes. The radio may identify a line-of-sight (LOS) beam based on the maximum amplitude. The radio may input the set of beam parameters associated with the LOS beam into a navigation function.

    摘要: A method (400) for use in providing network coverage to a vehicle (191, 192). The method includes obtaining (s402) first position information indicating a first position of the vehicle. The method also includes using (s404) the first position information to obtain first directional information indicating a first direction to the vehicle from a first transmitting and receiving point, TRxP (105), of or connected to a first network node (104). And the method further includes triggering (s406) the first network node to use the first TRxP to transmit a signal in the indicated first direction.

    摘要: Methods and apparatuses for Multi-AP channel sounding for Wireless Area Networks (WLAN) are disclosed. A method performed by a beamformee may compromise: receiving, from a beamformer, a null data packed (NDP) announcement frame (NDPA); receiving, from the beamformer, an NDP frame; receiving, from the beamformer, an enhanced beamforming request poll (BFRP) trigger frame including an indication of a feedback format; and transmitting, to the beamformer based on the NDP and NDPA, using a format indicated by the feedback format of the BFRP trigger frame, a feedback frame including a feedback report. The trigger frame may be an enhanced beamforming report poll (BFRP) trigger frame. The feedback report may be a beamforming report or a vector index (VI) feedback report. The beamformer may be an access point (AP) and the beamformee may be a station (STA).

    摘要: There is provided mechanisms for signalling TCI states. A method is performed by a network node. The network node is configured to control transmission of reference signals from at least two TRPs. The method comprises signalling, towards user equipment is served by the network node, a sequence of TCI states defined for a reference signal burst in which the reference signals are to be transmitted from the TRPs. At least one of the TCI states in the sequence of TCI states is representative of one of the reference signals to be jointly transmitted on a beamform from a first TRP of the TRPs and on a beamform from a second TRP of the TRPs. The method comprises initiating transmission of the reference signal burst from the TRPs.
