Abstract: Examples pertaining to measuring the correlation between multiple-input multiple-output (MIMO) antennas in mobile communications are described. A controller measures an over-the-air (OTA) total radiated power (TRP) associated with each of a plurality of transmit precoding matrix indicator (TPMI) indices configured for a communication apparatus to perform single-layer transmissions to obtain a plurality of TRP values each associated with a TPMI index. Each TPMI index indicates a precoding matrix for a single-layer transmission. The controller calculates an envelope correlation coefficient (ECC) between two antennas of the communication apparatus according to the TRP values.

Abstract: Disclosed in the present application are a pilot sending and receiving method and device, configured to reduce a delay of receiving pilot data at a terminal, thus improving efficiency of channel estimation based on the pilot data. The pilot sending method provided in the present application comprises: determining a pilot data pattern configured for a user equipment device, the pilot data pattern comprising time-frequency position information of pilot data, and the time-frequency position information comprising position information of an initial time point of the pilot data in a subframe; and sending to the user equipment device, according to the pilot data pattern, the pilot data.

Abstract: Disclosed are a scheduling-free transmission method and apparatus. The method comprises: monitoring a service interaction state to obtain a service requirement evaluation result; determining whether the service requirement evaluation result represents a low service load, and if so, allocating dedicated resources to a terminal, otherwise, allocating shared resources to the terminal; acquiring a transmission result of data transmission carried out by the terminal based on the allocated resources; and based on the transmission result, sending response information to the terminal according to a pre-set dynamic response rule. In this way, a terminal can transmit data by means of dedicated resources when a service load is low, and the terminal transmits data using shared resources when the service load is high, thereby reducing time delays, preventing resource conflicts, and increasing the transmission rate and reliability.
