US 2022/0046499 A1 · METHOD AND APPARATUS FOR DETERMINING SIGNAL QUALITY INFORMATION OF FREQUENCY

Abstract

This application provides a method and an apparatus for determining signal quality information of a frequency. In this method, terminal devices do not need to perform inter-frequency measurement or inter-RAT measurement, but only need to perform intra-frequency measurement and report signal quality information of an intra-frequency to a network device, so that the network device can determine signal quality information of an inter-frequency. In this way, the network device may select a carrier for the terminal devices based on the signal quality information of the intra-frequency and the signal quality information of the inter-frequency. Clearly, because the terminal devices do not need to perform the inter-frequency measurement or the inter-RAT measurement, in addition to ensuing a carrier selection gain, the method can further ensure service continuity and service throughputs of the terminal devices, and avoid overheads of the inter-frequency measurement and the inter-RAT measurement.

A method for determining signal quality information of a frequency, comprising:

obtaining, by a network device, signal quality information, of a first frequency, from terminal devices, wherein the first frequency is a frequency used by a serving cell accessed by the terminal devices;
and
determining, by the network device, signal quality information of a second frequency based on the signal quality information of the first frequency and a stored first mapping relationship, wherein the second frequency is different from the first frequency, and the first mapping relationship is a mapping relationship between the signal quality information of the first frequency and the signal quality information of the second frequency.

An apparatus for determining signal quality information of a frequency, wherein the apparatus is used in a network device and comprises:

a communications unit, configured to obtain signal quality information, of a first frequency, from terminal devices, wherein the first frequency is a frequency used by a serving cell accessed by the terminal devices;
and
a processing unit, configured to determine signal quality information of a second frequency based on the signal quality information of the first frequency and a stored first mapping relationship, wherein the second frequency is different from the first frequency, and the first mapping relationship is a mapping relationship between the signal quality information of the first frequency and the signal quality information of the second frequency.

A non-transitory computer readable medium, wherein the non-transitory computer readable medium stores instructions that are executable by a computer, and the instructions comprise instructions for:

obtaining signal quality information, of a first frequency, from terminal devices, wherein the first frequency is a frequency used by a serving cell accessed by the terminal devices;
and
determining signal quality information of a second frequency based on the signal quality information of the first frequency and a stored first mapping relationship, wherein the second frequency is different from the first frequency, and the first mapping relationship is a mapping relationship between the signal quality information of the first frequency and the signal quality information of the second frequency.
