摘要： A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives, by a user equipment (UE) during a first subframe, an indication of a dynamic uplink/downlink (UL/DL) subframe configuration. The apparatus determines an uplink hybrid automatic repeat request (HARQ) timing based on an uplink reference subframe configuration and at least one of the dynamic UL/DL subframe configuration or a downlink reference subframe configuration. The apparatus selects an uplink subframe for communication based on the determined uplink HARQ timing.

摘要： Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects, an eNB may compress a larger number of antenna elements to a smaller number of antenna ports. The eNB may use a port precoding matrix to transmit reference signals to a UE, receive feedback regarding CSI based on the reference signals, and transmit data to the UE, based on a mapping of multiple data layers and mapping of antenna ports to the physical antenna elements. Further, aspects include performing elevation beamforming by dynamically forming one or more vertical sectors based on UE feedback in the elevation domain.

摘要： Flexible beamforming is disclosed in which a base station receives feedback from a user equipment (UE), in which the feedback is related to one or more reference signals transmitted by the base station. The base station will obtain a tilt adjustment based, at least in part, on the feedback and generate an elevation precoding vector based using the feed-back. Using the tilt adjustment and elevation precoding vector, the base station may then perform elevation beamforming with an antenna array of the base station for the UE.

摘要： A wireless device may receive a first synchronization signal block (SSB) in a radio frequency band of a first cell of a neighbor base station, and report a physical cell identifier (PCI) for the first cell to a serving base station. The serving base station may identify, based on the PCI report, whether a radio frequency band of the first SSB is in or off a synchronization raster, and determine whether to instruct the UE to report a global cell identifier (CGI) for the neighbor base station (e.g., CGI for the neighbor cell) based on the identification. The wireless device may identify CGI based system information obtained from the neighbor cell, system information obtained from a master cell associated with the neighbor base station, system information obtained from CGI broadcast from the neighbor cell, or system information requested from the neighbor cell using dedicated resources, based on the instruction.

摘要： A user equipment (UE) may initiate a random access (RACH) procedure using an uplink resource selected based on a corresponding received synchronization signal block. The UE may detect a random access procedure trigger. The UE may configure a selection threshold time. The selection threshold time may be based at least in part on a latency requirement of the UE. The UE may select a synchronization signal block having a corresponding uplink resource within the selection threshold time. The synchronization signal block and corresponding uplink resource satisfy one or more parameters or conditions. The UE may transmit a random access preamble on the corresponding uplink resource.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (HE) may support beam management to determine beams for communicating with a base station, measure characteristics of the beams, and periodically report the measurements to the base station. The beam management may include a beam failure recover), procedure, where the UE detects and resolves a beam failure with the base station. Additionally, the UE may perform radio link monitoring (RLM) on a set of reference signals configured by the base station to determine if a radio link (e.g, beamformed transmission) is synchronized or not between the UE and base station. In some cases, these RLM reference signals (RLM-RSs) may be reconfigured, where the reconfiguration may be based on the periodic beam measurement reports for beam management, a beam monitoring event trigger, a beam failure recovery, or a combination thereof.
