Detailed Description
The following detailed description of embodiments of the present invention will be made with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
In the 4G era, the cost and the implementation difficulty of the UE are considered, and the UE has only one uplink transmitting antenna. In the 5G era, with the development of technology and the demand of high frequency for uplink enhancement, various types of UEs will appear, such as uplink dual-transmission UEs or uplink 4-antenna UEs. Multiple uplink transmitting antennas bring more uplink gain, and the uplink gain has a certain influence on the selection of the camping cell. Theoretically, each doubling of the number of uplink transmit antennas would result in a 3dB uplink coverage gain. The uplink gain caused by multiple uplink transmitting antennas of the UE also needs to be considered in idle cell selection to ensure that different types of UEs can select a suitable cell for camping.
As shown in fig. 1, a method for selecting a camped cell according to an embodiment of the present invention is applied to a terminal, and the method includes:
In this embodiment of the present invention, the cell selection parameter may further include: minimum reference signal received power, received power offset related to PLMN priority, and offset related to transmit power of the terminal that are allowed to access the cell to be selected.
And 102, obtaining an uplink transmission gain compensation value according to the maximum uplink transmission gain.
In general, if a terminal has one uplink transmit antenna, the transmit gain G of the terminal is 0 dB; if the terminal has two uplink transmitting antennas, the transmitting gain G of the terminal is 3 dB; if the terminal has four uplink transmitting antennas, the transmitting gain G of the terminal is 6 dB.
In this step, the difference between the maximum uplink transmission gain and the transmission gain of the terminal is compared with 0. If the difference value between the maximum uplink transmission gain and the transmission gain of the terminal is greater than 0, determining the difference value between the maximum uplink transmission gain and the transmission gain of the terminal as an uplink transmission gain compensation value; otherwise, determining the uplink transmission gain compensation value to be 0.
And 103, obtaining a cell selection signal receiving power value according to the uplink transmission gain compensation value.
Specifically, in this step, the terminal first performs measurement to obtain the cell downlink reference signal received power of the cell to be selected. Then, calculating a first difference value between the cell downlink reference signal received power of the cell to be selected and the sum of the minimum reference signal received power allowed to access the cell to be selected and the received power offset related to the PLMN priority; calculating a second difference value of the first difference value and a compensation value related to the transmission power of the terminal; and calculating a third difference value between the second difference value and the uplink transmission gain compensation value, and taking the third difference value as a cell selection signal receiving power value.
Specifically, the cell selection signal received power value may be calculated according to the following formula:
Srxlev＝Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation
-Gcompensation
wherein Srxlev represents a cell selection signal received power value, Qrxlevmeas represents a cell downlink reference signal received power of a cell to be selected, Qrxlevmin represents a minimum reference signal received power allowed to access the cell to be selected, qrxlevmjnoffset represents a received power offset related to a PLMN priority, Pcompensation represents a compensation value related to a transmission power of the terminal, and Gcompensation represents an uplink transmission gain compensation value.
And step 104, obtaining the receiving quality value of the cell selection signal according to the cell selection parameter.

Firstly, the terminal can measure the receiving quality of the downlink reference signal of the cell, and according to the receiving quality of the minimum reference signal which is received from the base station and allowed to access the cell to be selected and the receiving power offset related to the PLMN priority, the receiving quality of the reference signal is determined according to the following modes:

wherein, Squal represents the receiving quality value of the cell selection signal, Qqualmeas represents the receiving quality of the cell downlink reference signal measured by the terminal, Qqualmin represents the minimum receiving quality of the reference signal allowed to access the cell to be selected, and Qqualminoffset represents the receiving quality offset related to the PLMN priority.
And 105, when the cell selection signal receiving power value and the cell selection signal receiving quality value are both greater than 0, determining that the cell to be selected meets the camping condition.
In the embodiment of the invention, the influence of uplink gains brought by a plurality of uplink transmitting antennas on the selection of the resident cell is considered, an uplink transmitting gain compensation value is determined, an uplink transmitting gain compensation value and a cell selection signal receiving quality value are further determined, and when the cell selection signal receiving power value and the cell selection signal receiving quality value are both greater than 0, the cell is determined to meet the resident condition. Therefore, the scheme of the embodiment of the invention can ensure that the terminal with different uplink transmission gains can be resided in a proper cell.

Here, the cell selection signal reception power value may be determined according to the following formula:
Srxlev＝Qrxlevmeas-(Qrxlevmin+Qrxlevminoffset)-Pcompensation+P
wherein Srxlev represents a cell selection signal received power value, Qrxlevmeas represents a cell downlink reference signal received power of a cell to be selected, Qrxlevmin represents a minimum reference signal received power allowed to access the cell to be selected, qrxlevmjnoffset represents a received power offset related to a PLMN priority, Pcompensation represents a compensation value related to a transmission power of the terminal, and P represents an uplink transmission gain.
In the embodiment of the present invention, the cell selection signal reception quality value is calculated in the same manner as in the prior art. Firstly, the terminal can measure the receiving quality of the downlink reference signal of the cell, and according to the receiving quality of the minimum reference signal which is received from the base station and allowed to access the cell to be selected and the receiving power offset related to the PLMN priority, the receiving quality of the reference signal is determined according to the following modes:
Squal＝Qqualmeas-(Qqualmin+Qqualminoffset)
wherein, Squal represents the receiving quality value of the cell selection signal, Qqualmeas represents the receiving quality of the cell downlink reference signal measured by the terminal, Qqualmin represents the minimum receiving quality of the reference signal allowed to access the cell to be selected, and Qqualminoffset represents the receiving quality offset related to the PLMN priority.
And step 204, 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 the residence condition.
