摘要： Systems and methodologies are described that facilitate synchronizing base stations in a wireless communication environment. A base station can receive a synchronization signal sent via a low reuse channel, which can be shared by a group of base stations. Further, the base station can align a clock associated therewith to the received synchronization signal. Moreover, the base station can coarsely align the clock to a first synchronization signal received upon a first subset of resources of the low reuse channel, and finely align the clock to a second synchronization signal received upon a second subset of resources (e.g., of the low reuse channel, of a separate channel, …), where the second subset of resources can be reserved for transmission from at least one base station with at least a predetermined level of synchronous accuracy.

摘要： Systems and methodologies are described that facilitate synchronizing timing among wireless nodes in a wireless communication network. A tracking wireless node can synchronize to a global positioning system (GPS) signal if available. Alternatively, the tracking wireless node can receive quality metrics related to one or more target nodes. The quality metrics can relate to parameters that can be utilized to evaluate the target node for timing synchronization. Based on the quality metrics, the tracking wireless node can select a target wireless node for timing synchronization. The tracking wireless node can subsequently synchronize timing with the target wireless node. In addition, the tracking wireless node can continually evaluate surrounding wireless nodes to detect whether other wireless nodes have higher quality metrics than the current target wireless nodes and can accordingly resynchronize with nodes having higher metrics.

摘要： Methods, systems, and devices for wireless communications are described. The described techniques may support determining analog beamforming and digital beamforming for SRS transmissions. A user equipment (UE) may receive a first control message that indicates a channel state information (CSI-RS) resource for determining precoding for a sounding reference signal (SRS) resource set, and the CSI-RS resource may be associated with a first beam configuration. The UE may receive a second control message that indicates a second beam configuration for transmitting an SRS in the SRS resource set. The second beam configuration may be associated with the first configuration. The UE may receive the CSI-RS according to the first beam configuration and transmit one or more SRSs according to the SRS resource set based on the second beam configuration.

摘要： Methods, systems, and devices for wireless communications are described. In one example, a method for wireless communication at a user equipment (UE) includes receiving a configuration signal from a base station that indicates a frequency domain density (FDD) for one or more channel state information reference signal (CSI-RS) ports and performing CSI-RS measurements for the one or more CSI-RS ports based at least in part on the indicated FDD. The method may include generating a CSI report using the CSI-RS ports based on the CSI-RS measurements and transmitting the CSI report. Another example includes a base station performing channel measurements on a wireless channel between the base station and a UE, determining an FDD for one or more CSI-RS ports at the UE based at least in part on the channel measurements, and sending a configuration signal that indicates an FDD for the one or more CSI-RS ports.

摘要： Methods related to wireless communication systems and scheduling channel state information operations and transmissions. A user equipment (UE) receives, from a base station (BS), a channel state information (CSI) computation request. The UE then identifies a first CSI measurement resource based on the CSI computation request. The UE determines CSI based on the first CSI measurement resource, and receives, from the BS, a CSI report transmission request associated with the first CSI measurement resource. The UE optionally transmits to the BS a CSI report based on the first CSI measurement resource or a different CSI measurement resource. Other features are also claimed and described.
