Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for determining terminal capabilities, and a computer-readable storage medium.
Background
In LTE internet of vehicles (V2X), each UE can only operate in one resource selection mode. The idle UE operates in mode4, and the resource selection mode of the connected UE is configured by the network. In NR V2X, since the UE needs to support multiple different V2X services, different V2X services have different QoS requirements, such as: minimum communication distance, reliability, time delay, etc. Thus, different V2X traffic may require different communication modes to support. In other words, one UE may need to operate in multiple resource selection modes simultaneously. For example, the UE may need to support both mode 1 (base station scheduling) and mode 2a (autonomous resource selection). Besides, the UE may also simultaneously operate under both LTE and NR Radio Access Technologies (RATs), such as LTEPC5 and NR sidelink, and implement simultaneous transmission over sidelink in a manner similar to dual connectivity.
Unlike LTE, the communication mode of NR V2X UEs is more complex. If the UE communication mode is completely dependent on the network configuration, the delay caused by the configuration update will not meet the NR V2X communication delay requirement.

Therefore, the UE has a certain autonomous decision-making right, the determination of the UE communication mode and the division of the UE capacity can be realized more flexibly, and the time delay caused by the fact that the UE communication mode completely depends on network configuration is avoided to a certain extent.
The method specifically comprises the following steps:

1) whether multiple communication modes are simultaneously supported, i.e., whether two or more of the following communication modes are simultaneously supported: LTEmode 3, LTE mode4, NR mode 1, NR mode 2a, NR mode 2b, NR mode 2c, NR mode 2d, NRmode 2 series.
2) Whether LTE PC5 and NR sidelink simultaneous transmission are supported;
here, a supported band combination list can also be reported;
this capability can be subdivided into whether or not a sidelink split bear, or duplicate, is supported;

Here, a supported band combination list can also be reported;
this capability can be subdivided into whether or not a sidelink split bear, or duplicate, is supported;

b. the UE determines whether a terminal side dependent UE communication mode, i.e. one or more of LTE mode4, and/or NR mode 2a, and/or NR mode 2b, and/or NR mode 2c, and/or NR mode 2d, and/or NR mode2 series, and/or LTE mode3, and/or NR mode 1, is enabled, and indicates the determined mode to the wireless network;

Thirdly, determining the band combination and/or the baseband processing capability used on each communication path (LTE Uu, NR Uu, LTE PC5, NR sidelink) of the UE;
1) as determined by the network: after the network is determined, the network is configured to the UE through RRC message;
2) when determined by the UE: determined by the UE RRC layer;
3) when determined by network and UE through RRC message negotiation:
a. the network indicates the band combination and/or the baseband processing capability which are determined to be used by the Uu port to the UE;
here, if the network side is dual connectivity, the Uu port capability of the UE needs to be negotiated between the radio network nodes before this step.
b. The UE confirms or suggests to modify the band combination and the baseband processing capability which are determined to be used by the Uu port;
here, if the Uu port capability is confirmed, the UE will indicate the band combination and/or baseband processing capability determined to be used on sidelink to the network;
