Description

Uplink carrier configuration method, device, equipment and storage medium

Technical Field

The present application relates to the field of communications, and in particular, to a method, an apparatus, a device, and a storage medium for configuring an uplink carrier.

Background

A New Radio (NR) system of a fifth generation mobile communication technology (5G) may include network devices (e.g., a base station) and terminal devices (e.g., a mobile phone). Imbalance of uplink and downlink coverage is often observed in 5G NR systems. The imbalance of the uplink and downlink coverage generally means that the uplink coverage is smaller than the downlink coverage. The reason why the uplink coverage is smaller than the downlink coverage is: in a 5G NR system, a base station and a mobile phone mainly carry out uplink and downlink through a carrier wave of a C-band (C-band); the carrier frequency of the C band is high, the wavelength is short, the diffraction is poor, the propagation distance is short, the base station can transmit the carrier of the C band to the mobile phone with a long distance (the downlink coverage is large) through a large transmission power (for example, 200 watts (W)), and the mobile phone can transmit the power of the carrier of the C band to the base station with a short distance (the uplink coverage is small) only through a small power (for example, 0.2W).

In order to solve the unbalanced uplink and downlink coverage, a Supplementary Uplink (SUL) technology is proposed in the 3rd generation partnership project (3 GPP). The SUL technology is a technology in which a mobile phone uses a carrier of a frequency band with a low frequency as an uplink carrier to realize a large uplink coverage. The lower frequency bands may be referred to as SUL bands. In the current SUL technology, a mobile phone may measure Reference Signal Received Power (RSRP) of a downlink carrier of a C band (that is, the downlink carrier is the C band) and report the RSRP to a base station, and when the RSRP of the downlink carrier of the C band is smaller than a preset power threshold, the base station may instruct the mobile phone to use a carrier of the SUL band as an uplink carrier.

However, the bandwidth of the SUL band is low, and the rate when the carrier switched to the SUL band is used as an uplink carrier for communication may be low, so that the user experience is poor.

In order to solve the unbalanced uplink and downlink coverage, a Supplementary Uplink (SUL) technology is proposed in the 3rd generation partnership project (3 GPP). The SUL technology is a technology in which a mobile phone uses a carrier of a frequency band with a low frequency as an uplink carrier to realize a large uplink coverage. The lower frequency bands may be referred to as SUL bands. Fig. 1 is a schematic view of an application scenario of the SUL. As shown in fig. 1, the communication between the base station 101 and the handset 102 can be divided into case 1 and case 2.

In case 1, the base station 101 uses the carrier of the C band as a downlink carrier to send information to the handset 102 (denoted by DL @ C-band in fig. 1); the handset 102 also transmits information to the base station using the carrier in the C-band as an uplink carrier (denoted as UL @ C-band in fig. 1). In case 1, the uplink coverage is smaller, and is affected by the smaller uplink coverage, and the uplink and downlink coverage is smaller as a whole.

Case 2, the base station 101 sends information to the handset 102 using the carrier of the C band as a downlink carrier (denoted by DL @ C-band in fig. 1); the handset 102 uses the Sub 3G band carrier as an uplink carrier to transmit information (denoted by UL @ Sub 3G in fig. 1) to the base station 101. The uplink coverage in case 2 is larger than the uplink coverage in case 1, and the uplink and downlink coverage in case 2 is generally larger than that in case 1.

The frequency band used by the 5G NR system defined by 3GPP may include a Frequency Range (FR) 1 frequency band, and the FR1 frequency band may include 450 megahertz (MHz) to 6000 MHz. The FR1 frequency band may include the C band. The C band may include 3000MHz to 6000 MHz. The FR1 frequency bands may also include Normal Uplink (NUL) frequency bands corresponding to various operators. For example, 2496MHz to 2690MHz, and 3300MHz to 3800MHz, and the like. The FR1 frequency bands may in turn comprise Sub 3G frequency bands. The Sub 3G band may include a band below 3000MHz, and the Sub 3G band may be regarded as an SUL band. For example, 700MHz, 800MHz, 900MHz, 1800MHz, 2100MHz, etc.

In the current SUL technology, a mobile phone may measure Reference Signal Received Power (RSRP) of a downlink carrier of a C band (that is, the downlink carrier is the C band) and report the RSRP to a base station, and when the RSRP of the downlink carrier of the C band is smaller than a preset power threshold, the base station may instruct the mobile phone to use a carrier of the SUL band as an uplink carrier.

In this background, the present application provides an uplink carrier configuration method, which may be applied to a network device, and the network device may be connected to a terminal device. The network device may include a base station, such as: next generation Node (gNB), evolved Node B (eNB), and so on. The terminal device may include a User Equipment (UE) such as a mobile phone and a tablet. The specific types of the network equipment and the terminal equipment are not limited in the application.

Wherein, IBLER corresponding to each frequency band in the aforementioned NUL frequency band and each SUL frequency band is preset in the network device. In the method, the network device can configure the uplink carrier for the terminal device according to the requirement of the first service, and the probability that the configured uplink carrier can meet the requirement of the first service is higher, so that the use experience of a user is improved.
