Embodiment Construction

[0061] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0062] Considering the cost and implementation difficulty of the UE in the 4G era, the UE has only one uplink transmit antenna. In the 5G era, with the development of technology and the need for high-frequency uplink enhancement, various types of UEs will appear, such as uplink dual-transmission UEs or uplink 4-antenna UEs. Multiple uplink transmit antennas will bring more uplink gain, and the uplink gain will have a certain impact on the selection of the camping cell. Theoretically, every time the number of uplink transmit antennas doubles, a 3dB uplink coverage gain will be obtained. The uplink gain brought by the multiple uplink transmit antennas of the UE also needs to be considered...

Abstract

The present invention provides a method and a device for selection of a residing cell and a computer readable storage medium, and relates to the technical field of communication. The objective of theinvention is to allow terminals having different uplink emission gains to select appropriate residing cells. The method comprises the steps of: receiving cell selection parameters broadcasted by a base station, wherein the cell selection parameters comprise the maximum uplink emission gain allowed by a cell to be selected; obtaining an uplink emission gain compensation value according to the maximum uplink emission gain; obtaining a cell selection signal receiving power value according to the uplink emission gain compensation value; obtaining a cell selection signal receiving quality value according to the cell selection parameters; and when the cell selection signal receiving power value and the cell selection signal receiving quality value are both larger than 0, determining that the cell to be selected meets a residing condition. The method and the device for selection of the residing cell and the computer readable storage medium can allow the terminals having different uplink emission gains to be resided to appropriate cells.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, equipment and computer-readable storage medium for selecting a cell to reside on. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, idle state UE (User Equipment, user equipment) according to RSRP (Reference Signal Receiving Power, reference signal receiving power) and RSRQ ((Reference Signal Receiving Quality, reference signal receiving quality) Select the cell to camp on. Among them, RSRP and the cell downlink RSRP measured by the UE, the minimum RSRP allowed to access the cell, the offset related to the PLMN (Public Land Mobile Network, public land mobile network) priority, and the transmit power level related to the compensation value. [0003] In the past, UEs supporting LTE technology generally had only one uplink antenna, but in future 5G systems, UEs may have multiple uplink antennas. In the prior ...
