As shown in Figure 1, a method for transmitting user equipment capabilities provided by an embodiment of the present disclosure can be applied to a wireless communication system 100, which may include but is not limited to a network device 101 and a user equipment 102. The user equipment 102 is configured to support carrier aggregation, and the user equipment 102 can be connected to multiple carrier units of the network device 101, including a primary carrier unit and one or more secondary carrier units.

It should be understood that the above wireless communication system 100 can be applied to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include but are not limited to long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, global Internet microwave access (worldwide interoperability for micro wave access, WiMAX) communication system, cloud radio access network (cloud radio access network, CRAN) system, future fifth generation (5th-Generation, 5G) system, new wireless (new radio, NR) communication system or future evolved public land mobile network (public land mobile network, PLMN) system, etc.

The user equipment 102 shown above can be a user equipment (UE), a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal ( mobile terminal), wireless communication equipment, terminal agent or user equipment, etc. The user equipment 102 may have a wireless transceiver function, which can communicate (such as wireless communication) with one or more network devices 101 of one or more communication systems, and accept network services provided by the network device 101. Here, the network device 101 Including but not limited to the base station shown in the figure.

Among them, the user equipment 102 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, Handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, user equipment in future 5G networks or user equipment in future evolved PLMN networks, etc.

The network device 101 may be an access network device (or access network site). Among them, access network equipment refers to equipment that provides network access functions, such as wireless access network (radio access network, RAN) base stations and so on. Network equipment may specifically include base station (BS) equipment, or include base station equipment and wireless resource management equipment used to control base station equipment, etc. The network equipment may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations, etc. Network devices can be wearable devices or vehicle-mounted devices.

When user equipment uses carrier aggregation technology, the different carriers used will have different MIMO capabilities supported by different carriers due to differences in geographical location of the base station relative to the user equipment and differences in transmission path losses.

When the carrier aggregation technology used by the user equipment uses intra-band co-location (intra-band collocated), the user equipment can report the maximum number of MIMO layers supported by each carrier in the same frequency band through maxNumberMIMO-LayersPDSCH. A single frequency band can support up to 4 MIMO layers.

However, the number of MIMO layers that the user equipment can support is related to the number of antennas of the user equipment and the layout parameters of the antennas. In the case of non-collocated, due to the change of base station location, the number of user equipment reaching the base station increases. The path effect also changes accordingly, so even within the same frequency band, the number of MIMO layers that user equipment can support may be different.

If the network still performs MIMO scheduling for terminals based on the number of MIMO layers supported under co-location, it may cause the user equipment to be unable to correctly complete data transmission due to differences in capabilities.

In order to enable network equipment to better perform MIMO scheduling for intra-band non-collocated CA, user equipment needs to be able to support the number of MIMO layers in intra-band non-collocated CA scenarios. Reporting is carried out to facilitate the network to better complete scheduling, improve the utilization of wireless resources and the data processing efficiency of user equipment.

When the first indication information indicates the intra-band co-location type, the user equipment determines that the intra-band carrier aggregation type is the intra-band co-location type;

When the first indication information indicates the intra-frequency band non-co-location type, the user equipment determines that the intra-frequency band carrier aggregation type is the intra-frequency band non-co-location type.

Step S203: The user equipment sends capability indication information to the first network device.

The degree of difference in received power between the first downlink reference signal and the second downlink reference signal is the difference between the received power of the first downlink reference signal and the received power of the second downlink reference signal.

For example: if the received power of the first downlink reference signal is p1 and the received power of the second downlink reference signal is p2, the degree of power difference can be called Δp, and the value of Δp is p1-p2.

Alternatively, the received power difference between the first downlink reference signal and the second downlink reference signal is a difference between the power level of the first downlink reference signal and the power level of the second downlink reference signal.

For example: if the received power level of the first downlink reference signal is L1 and the received power level of the second downlink reference signal is L2, the power difference degree can be called ΔL, and the value of ΔL is L1-L2.

The degree of power difference can also be the ratio of the difference between the two to a fixed value. If the received power of the first downlink reference signal is p1 and the received power of the second downlink reference signal is p2, the degree of power difference can be called p', and the value of p' is (p1-p2)/p0, where p0 is a fixed value.
