Embodiment 1

[0073] The neighbor cell measurement method in this embodiment is applied to an NR terminal. like 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 of antenna time-sharing reception;

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

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

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

[0078] When M=4,...

Embodiment 2

[0088] like 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 each measurement frequency point in the frequency point list to be measured needs to receive and save in a unit time;

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

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

Embodiment 3

[0123] The neighbor cell measurement method in this embodiment is applied to an NR terminal.

[0124] like image 3 As shown, the measurement system of the adjacent area 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 the measurement frequency points to support N times of antenna time-sharing reception.

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

[0127] There is no intersection between the antenna sets corresponding to the target receiving antennas received by the antenna time-sharing each time, and the antenna set formed by all the target receiving antennas corresponding to t...

Abstract

The invention discloses a measurement method, system, electronic equipment and storage medium for adjacent cells. The measurement method includes: configuring a measurement frequency point to support N times of antenna time-division reception; The target receiving antenna received at the same time receives data; according to the data received by the target receiving antenna, obtain the measurement results respectively corresponding to the M receiving antennas of the adjacent cell under the target measurement frequency point; according to the target measurement frequency point Obtain the target measurement value of the neighboring cell based on the measurement result. In the present invention, the measurement frequency point realizes the measurement effect of M receiving antennas in the neighboring cell of the frequency point through N times of antenna time-sharing reception and processing, and effectively reduces the amount of data cached per unit time while maintaining mobility requirements , reducing the bandwidth requirement of cell measurement for DDR read / write, ensuring the effective bandwidth of cell measurement, and improving the performance of cell reselection and handover.
