摘要： A base station includes a controller configured to configure an MRS resource set comprising a group of MRS resources, each MRS resource comprising a set of MRS antenna ports. If at least two MRS antenna ports belong to a same MRS resource, then the at least two MRS antenna ports are quasi co-located with respect to a first set of QCL parameters, else if the at least two MRS antenna ports belong to a same MRS resource set, then the at least two MRS antenna ports are quasi co-located with respect to a second set of QCL parameters, and else the at least two MRS antenna ports are not quasi co-located with respect to either the first set or the second set of QCL parameters. The MRS is a CSI-RS for estimating a CSI and at least one of the first set and the second set of QCL parameters.

摘要： A system and method for device to device (D2D) network-assisted device discovery are provided. The method includes initiating the D2D network-assisted device discovery of a receiving UE to enable a target UE and the receiving UE to establish a D2D communication. The method also includes performing a discovery feasibility measurement to determine whether a D2D communication between the target UE and the receiving UE is feasible. The method further includes transmitting a discovery setup message and receiving a discovery report from the target UE.

摘要： A method includes determining, at a first eNodeB (eNB) associated with a first cell of a network, that a first user equipment (UE) is to engage in a device discovery process. The method also includes coordinating parameters of the device discovery process with a second eNB. The second eNB is associated with a second cell of the network and with a second UE. The parameters define one or more resources to be used in the first and second cells during the device discovery process. The method further includes communicating at least some of the parameters to the first UE. The device discovery process includes a process in which the first UE identifies one or more other UEs with which the first UE is able to engage in device-to-device communications.

摘要： A multistage beamforming circuit includes a data unit that implements a frequency domain beamforming stage and a remote radio head that implements a time-domain broadband beamforming stage. The data unit implements the frequency domain beamforming stage by converting K received data streams into M precoding output streams in a frequency-domain. The data unit is configured to transform the M output streams to M OFDM time-domain signals. The remote radio head, or integrated radio unit is configured to implement a time-domain broadband beamforming stage by converting the M OFDM time-domain signals into N transmit streams of time-domain samples. The remote radio head, or integrated radio unit includes a transmit antenna array configured to transmit the N transmit streams that together form broadcast beams and user-specific beams. The antenna array includes a plurality of physical antennas. The number N of transmit streams is greater than the number M of precoding output streams.
