The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

As shown in fig. 1, the method for transmitting carrier aggregation capability provided by the embodiment of the present disclosure may be applied to a wireless communication system 100, which may include a user equipment 101 and a network device 102. Wherein the user equipment 101 is configured to support carrier aggregation, the user equipment 101 may be connected to a plurality of carrier units of the network device 102, including one primary carrier unit and one or more secondary carrier units.

It should be understood that the above wireless communication system 100 is applicable to both low frequency and high frequency scenarios. The application scenarios of the wireless communication system 100 include, but are not limited to, a Long Term Evolution (LTE) system, a Frequency Division Duplex (FDD) system, a Time Division Duplex (TDD) system, a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a Cloud Radio Access Network (CRAN) system, a future fifth Generation (5th-Generation, 5G) system, a New Radio (NR) communication system, or a future evolved Public Land Mobile Network (PLMN) system.

The user equipment 101 shown above may be User Equipment (UE), terminal (terminal), access terminal, terminal unit, terminal station, Mobile Station (MS), remote station, remote terminal, mobile terminal (mobile terminal), wireless communication equipment, terminal agent or terminal equipment, etc. The user equipment 101 may be capable of wireless transceiving, and may be capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, including but not limited to the illustrated network device 102.

The user equipment 101 may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN network, and the like.

Network device 102 may be an access network device (or access network site). The access network device refers to a device providing a network access function, such as a Radio Access Network (RAN) base station, and the like. The network device 102 may specifically include a Base Station (BS), or include a base station and a radio resource management device for controlling the base station, and the like. The network device 102 may also include relay stations (relay devices), access points, and base stations in future 5G networks, base stations or NR base stations in future evolved PLMN networks, and so on. The network device 102 may be a wearable device or a vehicle-mounted device. The network device 102 may also be a communication chip having a communication module.

In the Carrier aggregation technology, two or more Component Carriers (CCs) can be aggregated together, thereby achieving the effect of increasing the bandwidth and improving the uplink and downlink transmission rates.

For carrier aggregation within a band, the user equipment 101 can report the supported bandwidth on each carrier in a given band combination through BCS4/BCS5 signaling.

The user equipment 101 may report the maximum channel bandwidth supported on each carrier through signaling supported bandwidth ul/supported bandwidth dl, and when the aggregation bandwidth of the maximum channel bandwidth on each carrier exceeds the maximum aggregation bandwidth that can be supported by the network equipment 102 or the maximum aggregation bandwidth that is supported by the frequency band, the network equipment 101 may autonomously eliminate invalid combinations that exceed the maximum aggregation bandwidth in theory. However, due to the influence of the performance of the user equipment 101, for carrier aggregation in some frequency bands, the user equipment 101 cannot support the maximum aggregation bandwidth to reach the theoretical maximum aggregation bandwidth supported by the frequency bands, and the network equipment 102 cannot directly eliminate invalid combinations through bandwidths supported by carriers reported by the user equipment 101. Therefore, how the network device 102 configures carrier aggregation for the user equipment 101 within the effective aggregation bandwidth is a problem to be solved.
