Description

Measuring method, device, equipment and readable storage medium
Technical Field
The embodiment of the application relates to the technical field of communication, in particular to a measuring method, a measuring device, measuring equipment and a readable storage medium.
Background
In order to meet the requirements of partial use cases of the internet of things, such as industrial wireless sensor networks, smart cities and wearable devices, the complexity and cost of a light (Reduced capability, Redcap) terminal are Reduced by reducing the bandwidth, the number of transmitting and receiving antennas, the processing capacity of the terminal and other methods.
The Bandwidth Part (BWP) of the red beacon terminal is reduced, e.g., limited to 20MHz Bandwidth, and the frequency selective scheduling gain of the red beacon terminal is smaller, which causes coverage degradation problem. In order for red cap to maintain a coverage level comparable to Mobile Broadband enhancement (eMBB), companies have proposed BWP hopping over full bandwidth to Enhance coverage. The selection of the BWP frequency hopping point requires the known full bandwidth Channel State Information (CSI), and generally, the better CSI BWP brings larger coverage gain. To obtain the frequency selective gain, the network needs to acquire CSI over the full bandwidth, e.g., over a 100MHz bandwidth.
In the prior art, CSI measurement is performed on a per BWP (per BWP) basis, and a terminal may configure 4 BWPs at most, but only activate one BWP at the same time, and perform CSI measurement only on the activated BWP. To measure the CSI of other BWPs, the ue needs to switch to other BWPs for measurement. There are three existing BWP switching methods, which are Radio Resource Control (RRC) configuration, timer triggering, and dynamic Downlink Control Information (DCI) indication. The full-bandwidth CSI is difficult to obtain by using the existing CSI measurement technology, so a full-bandwidth CSI measurement mechanism needs to be established, for example, a CSI measurement pattern (pattern) is configured to implement full-bandwidth CSI measurement.
However, when the terminal measures the full-bandwidth CSI according to a certain measurement pattern, how to avoid possible conflicts with scheduled data transmission is an urgent problem to be solved.

Time Δ T to T CSI-RS While not measuring but monitoring BWP where the measurement resource is or PDCCH activating BWP, if notSchedule is monitored at time T CSI-RS Measurement of BWP1 begins according to the CSI measurement pattern. The CSI measurement pattern is normally performed until at time T 1 The schedule is snooped, and the scheduled active BWP is BWP 0. Stopping periodic CSI measurement pattern, starting a timer, switching to BWP0 for data transmission, simultaneously measuring on BWP0 with configured CSI period, and at time T 2 Data transmission ends, but still within the timer expiration, continues to measure on BWP0 and listen for PDCCH.
