Techniques for delay reduction and power optimization using a set of antenna modules
Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish a wireless connection with a primary cell and may identify a set of antenna modules of the UE and multiple sets of receive beams. Each set of receive beams may include at least one beam from each antenna module. The UE may perform a measurement procedure on signals received from one or more candidate secondary cells using at least a first set of receive beams. The UE may then transmit, to the primary cell, a measurement report based on performing the measurement procedure upon determining that at least one of the multiple sets of receive beams satisfies a threshold value and before performing the measurement procedure on signals received from the one or more candidate secondary cells using at least one remaining set of receive beams.
METHOD AND APPARATUS FOR TRANSMISSIONS VIA MULTIPLE BEAMS IN A WIRELESS COMMUNICATION SYSTEM
A method for a wireless communications system is disclosed. In one example, user equipment (UE) (e.g. a mobile phone) receives an indication from a network (for example, by way of a transmission and reception point (TRP)) indicating whether a first transmission and a second transmission to the UE can be combined for decoding. The UE also receives the first transmission via a first UE beam and the second transmission via a second UE beam. The first transmission and the second transmission are received concurrently. The first and second transmissions can arrive via different serving beams and/or different TRPs of the same cell. Based on the indication, the UE combines the first and second transmissions for decoding purposes.
Establishing wireless communication in a system forming a beam by selecting from a pre-determined plurality of antenna weight vectors
Wireless communication is established between a first station and a second station in a wireless communication system, the first station having a beamforming network configured to form a succession of beams using antenna weight vectors selected from a pre-determined plurality of antenna weight vectors. The orientations of the beams are arranged in a grid comprising a plurality of rows. The beams of each row are spaced in angular position such that at least one beam in a respective row is positioned mid-way between the positions of two beams on an adjacent row. A succession of beams is formed to send first messages using a selected first sub-set of the antenna weight vectors. If a first message in a first beam is received at the second station, a further succession of beams is formed using a second sub-set of the antenna weight vectors selected to form beams adjacent to the first beam.

METHOD AND DEVICE FOR TRANSMITTING/RECEIVING CSI-RS IN WIRELESS COMMUNICATION SYSTEM
A method and a device for transmitting/receiving a CSI-RS in a wireless communication system are disclosed. A method for receiving an aperiodic channel state information-reference signal (CSI-RS), according to one embodiment of the present disclosure, may comprise steps of: receiving, from a base station, downlink control information (DCI) for triggering the aperiodic CSI-RS; and receiving, from the base station, the aperiodic CSI-RS on the basis of the DCI, wherein, on the basis the scheduling offset of the aperiodic CSI-RS being smaller than the beam switch timing of a terminal, a quasi co-location (QCL) assumption of a downlink signal associated with the same CORESET pool index as the CORESET pool index of a control resource set (CORESET) for the DCI can be applied for the reception of the aperiodic CSI-RS.
