Description

Method for reporting and processing user capability, user equipment and base station

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a method, a user equipment, and a base station for reporting and processing user capabilities.

Background

In a mobile communication system in a wireless communication technology, user Equipment (UE) and a base station are generally used to transmit and receive wireless signals on a wireless channel, so as to implement data and information transmission. For a Long Term Evolution (LTE) system, technical specification TS36.101 of 3GPP defines multiple Power classes (Power classes) available for user equipment according to Maximum Output Power (Maximum Output Power) of different user equipments, so as to be used by UEs with different capabilities (capabilities), sizes and design purposes. For example, most common LTE common user terminals adopt a third Power Class (Power Class 3) with a maximum transmission Power of 23dBm, and vehicle terminals generally used in the public safety field can adopt a first Power Class (Power Class 1) with a maximum transmission Power of 31 dBm. It is noted that the power level at each frequency Band (Band) need not be the same for a certain user equipment. In the standard of LTE Release-13, the 3GPP technical specification TS36.101 adds corresponding specifications and technical requirements, thereby introducing a high Power user equipment of the second Power Class (Power Class 2) for general use operating on the band 41, and the maximum transmission Power of the high Power user equipment in the single carrier operating mode of the band 41 is 26dBm. Correspondingly, the 3GPP also introduces a signaling and a signaling flow for reporting the corresponding power level by the ue.

The maximum output power (P) configured by the ue is also given in TS36.101 _CMAX,c Configured Maximum Output Power), in which the Maximum Output Power P configurable by the ue is determined according to the Maximum Output Power corresponding to the Power class of the ue, the commands issued by other base stations, and other parameters given by the specification _CMAX,c And determining the maximum output power P configured by the user equipment according to the range _CMAX,c . And the maximum output power P configured by the user equipment determined by the process _CMAX,c Will be further used for the Transmit Power Control (Transmit Power Control) procedure of the base station for the user equipment.

It should be noted that the maximum output power corresponding to the above-mentioned different power levels is measured by a conductivity Test (Conductive Test), and accordingly, the ue needs to determine that the maximum transmit power of the ue is qualified by the conductivity Test. However, it is generally considered that the conductivity test can only perform performance verification and authentication of maximum transmission power for the user equipment operating in a relatively low frequency band (e.g., a frequency band below 6 GHz); for a user equipment operating in a relatively high frequency band (for example, a millimeter wave frequency band higher than 6 GHz), it is generally considered that The performance verification and authentication can be completed only by an OTA (Over-The-Air) test performed in a dark room.

With the explosion of users' demands for high-bandwidth mobile communication system services, mobile communication operators are beginning to consider utilizing higher frequency bands (even millimeter wave frequency bands) higher than 6GHz as one of the main operating frequency bands of the next-generation mobile communication systems. In these high frequency bands, the frequency spectrum resources used by mobile communication can be relatively more allocated to various countries in the world, so that the huge demands of users in various countries on the services of the high-bandwidth mobile communication system can be met. To meet this trend, the 3GPP organization is currently discussing and researching New generation wireless communication technology (NR). In this discussion, 3GPP has agreed that OTA-based performance indicators, including but not limited to Total Radiated Power (TRP) and Equivalent Isotropic Radiated Power (EIRP), can be used to establish Power levels for ues operating at frequencies above 6 GHz. Similar to the case in 4G LTE, the power level of the user equipment above 6GHz in NR and other measurements will also be used directly or indirectly for transmission power control of the user equipment.

It is considered that the ue with an operating frequency higher than 6GHz can obtain the same Uplink Coverage (Uplink Coverage) capability by selecting different Uplink Beamforming (Beamforming) schemes, that is, the different schemes all achieve the same EIRP in the direction in which the ue is pointed. In order to ensure that the user equipment can have application flexibility, a scheme should be allowed as long as the uplink coverage capability required by the standard can be reached. Obviously, the Maximum total radiated power (Maximum TRP) for these schemes that can achieve the uplink coverage capability required by the standard is not necessarily the same.

How to report the corresponding capability of the ue with different maximum total radiation power, how to handle the packet with the capability report information of the ue based on the total radiation power, and how to reasonably apply the capability of the ue in the corresponding scenario are main problems to be solved by the present application.

For the purpose of making the objects, technical means and advantages of the present application more apparent, the present application will be described in further detail with reference to the accompanying drawings.

In the technical solution provided by the present invention, it is considered that different ue can obtain the same uplink coverage capability by selecting different uplink beamforming schemes, and therefore, the maximum TRP determined by different ue may be different. Based on the above situation, the present application provides a method for reporting and processing UE capability, by which a UE is allowed to determine a parameter value of the UE capability that the base station requires to report, for its own design and radio frequency capability, based on a maximum TRP that the UE can achieve, and report corresponding capability information to the base station. By the method, the user equipment can have application flexibility, and the base station can realize reasonable UE control aiming at TRP indexes of different UE schemes.

The method for reporting and processing the UE capability comprises the processing of the UE side and the processing of the base station side. The following description is made separately.
