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

The New Radio (NR) system of the fifth generation mobile communication technology (5th generation mobile communication technology,5G) may include devices such as a network device (e.g., a base station) and a terminal device (e.g., a handset). The situation of unbalanced uplink and downlink coverage areas often occurs in the 5G NR system. Uplink and downlink coverage imbalance 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 that: in a 5G NR system, a base station and a mobile phone mainly perform uplink and downlink through a carrier wave of a C-band (C-band); the carrier frequency of the C-band is higher, the wavelength is shorter, the diffraction is worse, the propagation distance is shorter, the base station can transmit the carrier of the C-band to the mobile phone with a longer distance (with a larger downlink coverage) through a larger 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 shorter distance (with a smaller uplink coverage) only through a smaller power (for example, 0.2W).

To address the case of imbalance in uplink and downlink coverage, supplemental uplink (supplementary uplink, SUL) techniques are proposed in the third generation partnership project (3rd generation partnership project,3GPP). SUL technology refers to that a mobile phone uses a carrier wave with a lower frequency band as an uplink carrier wave to realize a larger uplink coverage area. The lower frequency band may be referred to as the SUL band. In the current SUL technology, a mobile phone can measure the reference signal received power (REFERENCE SIGNAL RECEIVED power, RSRP) of a downlink carrier wave of a C-band (i.e. the downlink carrier wave is the C-band) and report the reference signal received power to a base station, and when the RSRP of the downlink carrier wave of the C-band is smaller than a preset power threshold, the base station can instruct the mobile phone to use the carrier wave of the SUL frequency band as an uplink carrier wave.

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

To address the case of imbalance in uplink and downlink coverage, supplemental uplink (supplementary uplink, SUL) techniques are proposed in the third generation partnership project (3rd generation partnership project,3GPP). SUL technology refers to that a mobile phone uses a carrier wave with a lower frequency band as an uplink carrier wave to realize a larger uplink coverage area. The lower frequency band may be referred to as the SUL band. Fig. 1 is a schematic view of an application scenario of a SUL. As shown in fig. 1, communication between the base station 101 and the mobile phone 102 can be divided into case 1 and case 2.

Case 1, the base station 101 uses a carrier wave of a C-band as a downlink carrier wave to send information (shown as dl@c-band in fig. 1) to the mobile phone 102; the handset 102 also transmits information (represented by ul@c-band in fig. 1) to the base station using the C-band carrier as an uplink carrier. The uplink coverage area of case 1 is smaller, and is affected by the smaller uplink coverage area, and the overall uplink and downlink coverage areas are smaller.

Case 2, the base station 101 uses a carrier wave of the C band as a downlink carrier wave to send information to the mobile phone 102 (shown as dl@c-band in fig. 1); the mobile phone 102 transmits information (shown as ul@sub 3G in fig. 1) to the base station 101 using a carrier of the Sub 3G band as an uplink carrier.

The FR1 band may include the C band. The C-band may include 3000MHz to 6000MHz. The FR1 band may also include Normal Uplink (NUL) bands corresponding to respective operators. For example 2496MHz to 2690MHz, 3300MHz to 3800MHz, and the like. The FR1 band may in turn comprise the Sub 3G band. The Sub 3G band may include a band of 3000MHz or less, and the Sub 3G band may be regarded as a SUL band. Such as 700MHz, 800MHz, 900MHz, 1800MHz, 2100MHz, etc.

In the current SUL technology, a mobile phone can measure the reference signal received power (REFERENCE SIGNAL RECEIVED power, RSRP) of a downlink carrier wave of a C-band (i.e. the downlink carrier wave is the C-band) and report the reference signal received power to a base station, and when the RSRP of the downlink carrier wave of the C-band is smaller than a preset power threshold, the base station can instruct the mobile phone to use the carrier wave of the SUL frequency band as an uplink carrier wave.

In the method, the network equipment can configure the uplink carrier for the terminal equipment according to the requirement of the first service, and the configured uplink carrier has high probability of meeting the requirement of the first service, so that the use experience of the user is improved.

Wherein the k1 parameter is used to determine the timing of a hybrid automatic repeat request (hybrid auto repeat request, H ARQ) for downlink transmissions. The k2 parameter is used to determine the uplink scheduling timing.

In some embodiments, after the network device determines the NUL frequency band and the M SUL frequency bands, the frequency band with the largest coefficient for the first service is used as the target frequency band corresponding to the terminal device, the target frequency band corresponding to the terminal device may be referred to as the first frequency band. When the network device detects that the first coefficient corresponding to the second frequency band is larger than the first coefficient corresponding to the first frequency band, the network device can update the second frequency band to the target frequency band.

That is, when the rate requirement, the time delay requirement, and the mobility requirement of the first service are changed, and/or the rate, the time delay, and the mobility matching coefficient corresponding to the NUL frequency band and the M SUL frequency bands respectively are changed, the network device may further determine, according to the rate requirement, the time delay requirement, and the mobility requirement of the changed first service, the rate, the time delay, and the mobility matching coefficient corresponding to the changed NUL frequency band and the M SUL frequency bands respectively, the coefficient corresponding to the updated NUL frequency band and the M SUL frequency bands respectively, and determine, among the NUL frequency bands and the M SUL frequency bands, the frequency band with the largest coefficient corresponding to the first service after updating as the updated target frequency band corresponding to the terminal device.

It may be understood that, according to the rate requirement, the time delay requirement, the mobility requirement, the rate, the time delay, and the mobility matching coefficient corresponding to the changed NUL frequency band and the M SUL frequency bands, the network device determines the coefficient corresponding to the first service corresponding to the updated NUL frequency band and the M SUL frequency bands, determines the frequency band with the largest coefficient corresponding to the first service in the NUL frequency band and the M SUL frequency bands, and uses the updated frequency band with the largest coefficient corresponding to the first service as the updated target frequency band corresponding to the terminal device, which is described in reference to S201 to S211 above and will not be repeated herein.

In the uplink carrier configuration method provided by the embodiment of the application, when the rate requirement, the time delay requirement and the mobility requirement of the first service are changed or the rates, the time delay and the mobility matching coefficients corresponding to the NUL frequency band and the M SUL frequency bands are respectively changed, the network equipment can also update the target frequency band corresponding to the terminal equipment in time according to the updated requirements and the network capability, so that the situation that the carrier of the original target frequency band cannot meet the requirement of the first service is avoided, and the use experience of a user is improved.
