Embodiment 1

[0073] The method for measuring neighboring cells in this embodiment is applied to an NR terminal. Such as figure 1 As shown, the measurement method of the neighboring cell in this embodiment includes:

[0074] S101, configure the measurement frequency point to support N times antenna time-sharing reception;

[0075] Among them, the time-division reception of N antennas at the measurement frequency point corresponds to the M receiving antennas used for each neighboring cell measurement in the NR terminal, 2≤N≤M, and M and N are integers;

[0076] There is no intersection between the antenna sets corresponding to the target receiving antennas for each antenna time-sharing reception, and the antenna set composed of all target receiving antennas corresponding to the N times of antenna time-sharing reception is M receiving antennas;

[0077] For example, when M=4, N=4 and the number of target receiving antennas for each antenna time-division reception is 1.

[0078] When M=4, N...

Embodiment 2

[0088] Such as figure 2 As shown, the measurement method of the adjacent cell in this embodiment is a further improvement to Embodiment 1, specifically:

[0089] Before step S101, it also includes:

[0090] S10101. Obtain the amount of data that needs to be received and saved per unit time for each measurement frequency point in the frequency point list to be measured;

[0091] S10102. Determine whether the amount of data is greater than the set threshold, if yes, perform step S101; if not, configure the measurement frequency point to support simultaneous reception by M receiving antennas.

[0092] Among them, each measurement frequency point can be independently configured to support antenna time-sharing reception, which mainly depends on the amount of data received and stored by the measurement frequency point per unit time. Taking M=4 as an example, when the amount of data received by the 4 receiving antennas is not greater than the set value, it is determined that the m...

Embodiment 3

[0123] The method for measuring neighboring cells in this embodiment is applied to an NR terminal.

[0124] Such as image 3 As shown, the adjacent cell measurement system in this embodiment includes a time-sharing configuration module 1 , a data receiving module 2 , a measurement result acquisition module 3 and a target measurement value acquisition module 4 .

[0125] The time-sharing configuration module 1 is used to configure measurement frequency points to support N times of antenna time-sharing reception.

[0126] Among them, the time-division reception of N antennas at the measurement frequency point corresponds to the M receiving antennas used for each neighboring cell measurement in the NR terminal, 2≤N≤M, and M and N are integers;

[0127] There is no intersection between the antenna sets corresponding to the target receiving antennas for each antenna time-sharing reception, and the antenna set composed of all target receiving antennas corresponding to the N times o...

Abstract

The invention discloses a neighbor cell measurement method and system, electronic equipment and a storage medium. The measurement method comprises the following steps: configuring a measurement frequency point to support N times of antenna time-sharing reception; under a target measurement frequency point, selecting the target receiving antenna received by each antenna in a time-sharing manner toreceive data; according to the data received by the target receiving antenna, obtaining measurement results respectively corresponding to the M receiving antennas of the neighbor cell under the targetmeasurement frequency point; and obtaining a target measurement value of the neighbor cell according to the measurement result. According to the invention, the measurement frequency point realizes the effect of measuring the M receiving antennas of the frequency point neighbor cell through N times of antenna time-sharing receiving and processing; according to the method, the mobility requirementis maintained, meanwhile, the amount of data cached in unit time is effectively reduced, the bandwidth requirement of cell measurement for DDR reading / writing is reduced, the effective bandwidth of cell measurement is ensured, and the performance of cell reselection and switching is improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a measurement method, system, electronic equipment and storage medium of a neighboring cell. Background technique [0002] At present, NR (New Radio, New Radio) terminals need to store a large amount of time-domain data offline when performing cell measurement, and the write / read bus bandwidth requirements for DDR (Double Data Rate, double-rate synchronous dynamic random access memory) If it is too high, on the one hand, it will cause the interruption of the hardware flow of the measurement accelerator, and the processing capacity will be reduced; The processing delay of other business modules.
