Abstract: A method for a user equipment (UE) is provided. The method comprises receiving, from a base station (BS), information via a dynamic signaling comprising at least one of a medium access control channel element (MAC CE) or downlink control information (DCI) that includes information for a set of channel state information-reference signal (CSI-RS); identifying CSI-RS resources each of which comprises a set of antenna ports based on the information; and measuring CSI using an aggregation of the CSI-RS resources, wherein an energy per resource element (EPRE) ratio between a CSI-RS and a physical downlink shared channel (PDSCH) is configured in the information to each of the CSI-RS resources comprising the aggregated CSI-RS resources.

Abstract: A wearable wireless communication device comprises a transceiver positioned on a first side of the device, the transceiver comprising a first antenna configured to receive radio frequency (RF) signals transmitted toward the first side of the device. The device is wearable about an object that attenuates reception, by the first antenna, of RF signals transmitted toward a second side of the device. The device further comprises a waveguide electromagnetically coupled to the transceiver, the waveguide terminating in at least a second antenna positioned on the second side of the device. The second antenna is configured to receive the RF signals transmitted toward the second side of the device. The waveguide is shaped to direct received RF signals around the object to the transceiver. The object may in some embodiments be a piece of human anatomy.

Abstract: An antenna array and a user equipment (UE) including the antenna array. The antenna array includes a plurality of unit cells. Each unit cells includes first and second patches, phase shift transmission lines, a third patch, and a transmission line. The first and second patches radiate at a first frequency band and positioned in a first plane of the antenna array. The phase shift transmission lines connect the first and second patches and shift a phase of a signal between the first and second patches. The third patch is positioned in a second plane of the antenna array and beneath the first patch and radiates at a second frequency band that is lower than the first frequency band. The transmission line excites at least the third patch.
