#中国移动宣布5G-A is officially commercial #

Recently,5GMany phones have announced support for 5G-A's ultra-high-speed new feature (carrier aggregation). Currently officially announced models include: Xiaomi 14 Ultra, FIND X7, and others

Saving Expenses:

Currently, phones with hardware support for 5G carrier aggregation technology

1. iPhone 13 + iOS 16.4 and later phones and systems

2. MediaTek Dimensity 9000 and later flagship SoC phones

3. Qualcomm Snapdragon 888 and later flagship SoCs, third-generation Snapdragon 7 and later mid-range SoC phones

4. Kirin Only supports non-scaled-down models of the 9000 series

Main Text:

In fact, 5G carrier aggregation was introduced in the 3GPP R16 specification (5G-A corresponds to the R18 standard). In theory, as long as the R16 standard and subsequent baseband chips support it, 5G carrier aggregation can be enabled.

Currently, according to public information, baseband chips supporting 5G carrier aggregation include:

1. MediaTek: MTK M80 and later high-end flagship models. Specifically, the SoC includes the Dimensity 9000 and later flagship models. MTK mid-range SoCs don't seem to support this feature.

2. Qualcomm: X60 and later high-end models, X57 unknown speculation that it may be supported

Corresponding SOC.

(1) Apple A15 (iPhone 13 series) and later models

X60 Baseband Characteristics Description

There is no publicly available supporting information for the iPhone SE3 (it is speculated that it does), and the X57 modem is customized by Apple, with no public specs available online.

(2) Qualcomm Snapdragon 888 and later flagship SOCs (surprised, huh? After all, Qualcomm started out in communications, so new feature deployments are always very forward-thinking. ）

Most of Qualcomm's mid-range SoCs seem unsupported, with only the Snapdragon X63 Gen 3 Snapdragon 7 supported.

(3) Kirin: Due to a technological gap, only the Kirin 9000 supports this model. It seems the 9000s is only supported on the top-spec X5. The Mate60 series does not use public data, but speed tests suggest it is not supported.

The latest and most powerful 5G-A SoC—Snapdragon 8 Gen 3:

Qualcomm's latest X75 baseband (8Gen3 baseband) can achieve ten-carrier aggregation in the millimeter wave band and five-carrier aggregation in the Sub-6GHz downlink band. The theoretical maximum speed can reach a downlink speed of 7.5Gbps.

Summary of Qualcomm X75 baseband communication characteristics

Currently, the only device on the market that fully supports the 3GPP-R18 specification is probably the Qualcomm Snapdragon 8 Gen 3. So if you want to experience a full-powered 5G-A, go for this SoC.

The Dimensity 9300 can only support up to 5G Sub-6GHz quad-carrier aggregation, which is slightly less than the 8Gen3. The iPhone 15 series' X70 modem also supports up to sub-6GHz quad-carrier aggregation.

To experience full-powered 5G-A, you still need the latest flagship SoC

The above is a summary and brief analysis of the market-supported 5G carrier aggregation SoCs based on public data statistics.

Of course, whether 5G carrier aggregation can be enabled properly depends on the strategies of operators and base stations.

Here's a way to check if carrier aggregation is enabled on iOS:

Enter *3001 on the dialing interface#12345#* Click to dial to enter

Enter the code to enter the debugging interface

Then click "NR connection status"

Click the NR connection status menu

You will see this interface

If the value of the aggregated_dl_bw is greater than 100, carrier aggregation is enabled

aggregated_dl_bw The number after it is greater than 100, indicating carrier aggregation is enabled.
