In some wireless communication technologies, a Carrier Aggregation (CA) technology is used to expand a transmission bandwidth of a user equipment. In the carrier aggregation technique, a plurality of Component Carriers (CCs) are aggregated together and uplink transmission or downlink reception is performed on the component carriers.

As shown in fig. 1, the method for transmitting user equipment capability provided by the embodiment of the present disclosure is applicable 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 may be connected to a plurality of carrier units of the network device 101, 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 102 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 device, terminal agent or user equipment, etc. The user equipment 102 may be capable of wireless transceiving, and may be capable of communicating (e.g., wirelessly communicating) with one or more network devices 101 of one or more communication systems and receiving network services provided by the network devices 101, where the network devices 101 include, but are not limited to, the illustrated base stations.

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, 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 user equipment in a future 5G network or a user equipment in a future evolved PLMN network, and the like.

Network device 101 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 may specifically include a Base Station (BS) device, or include a base station device and a radio resource management device for controlling the base station device, and the like. The network device 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 the like. The network device may be a wearable device or a vehicle mounted device. The network device may also be a communication chip having a communication module.

For example, network device 101 includes, but is not limited to: next generation base stations (gbnodebs, gnbs) in 5G, evolved node bs (enbs) in an LTE system, Radio Network Controllers (RNCs), Node Bs (NBs) in a WCDMA system, radio controllers under a CRAN system, Base Station Controllers (BSCs), Base Transceiver Stations (BTSs) in a GSM system or a CDMA system, home base stations (e.g., home evolved node bs or home node bs, HNBs), Base Band Units (BBUs), transmission points (TRPs), Transmission Points (TPs), or mobile switching centers (mscs), etc.

When the user equipment uses the carrier aggregation technology, the used different carriers may cause different MIMO capabilities that can be supported by different carriers due to the difference in the geographical location of the base station relative to the user equipment and the difference in the transmission path loss.

When the intra-band co-located (intra-band co-located) is used in the carrier aggregation technology used by the user equipment, the user equipment can report the maximum number of MIMO layers supported by each carrier in the same frequency band through the maxNumberberrMIMO-LayersPDSCH. The number of MIMO layers of 4 layers at most can be supported in a single frequency band.

However, the number of MIMO layers that can be supported by the ue is related to the number of antennas of the ue and the antenna arrangement parameters, and in the case of non-co-located (non-co-located), due to the change of the location of the base station, the multipath effect from the ue to the base station also changes, so that the number of MIMO layers that can be supported by the ue may be different even in the same frequency band.

If the network still performs MIMO scheduling on the terminal according to the number of MIMO layers supported under the co-located (collocated) condition, it may cause that the user equipment cannot complete data transmission correctly due to the problem of capability difference.

In order to enable the network device to perform MIMO scheduling of intra-band non-co-located carrier aggregation (intra-band non-co-located CA) better, the user equipment needs to report the MIMO layer number support capability of the user equipment in a non-co-located carrier aggregation scenario in the frequency band, so as to facilitate better completion of scheduling by the network, and improve the utilization rate of radio resources and the data processing efficiency of the user equipment.

In this disclosure, the first network device is a primary network device in carrier aggregation of the user equipment, and the second network device is a secondary network device in carrier aggregation of the user equipment.

An embodiment of the present disclosure provides a method for transmitting a capability of a user equipment, and fig. 2 is a flowchart illustrating a method for transmitting a capability of a user equipment according to an exemplary embodiment, as shown in fig. 2, the method includes steps S201 to S205, specifically:

step S201, a user equipment receives a configuration signaling sent by a first network device, where the configuration signaling includes first information, and the first information is used to indicate a carrier aggregation type in a frequency band.

The type of intra-band carrier aggregation indicated by the first information is one of:

intra-band collocated (intra-band collocated) type;

intra-band non-collocated (intra-band non-collocated) type.

Step S202, the ue determines that the intra-band carrier aggregation type is the intra-band carrier aggregation type indicated by the first information.

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

when the first indication information indicates an in-band non-co-location type, the user equipment determines that the in-band carrier aggregation type is the in-band non-co-location type.

Step S203, the ue sends capability indication information to the first network device.

The capability indication information is used for indicating the maximum MIMO layer number supported by each component carrier corresponding to the intra-band carrier aggregation type.

In some possible embodiments, the maxnumberbelmimo-LayersPDSCH is transmitted to the first network device in response to the in-band carrier aggregation type being an in-band co-sited type.

In response to the in-band carrier aggregation type being an in-band non-co-located type, transmitting maxNumberMIMO-LayersPDSCH-non-co-located to the first network device.

step S301, the first network device sends a first downlink reference signal to the ue, and the second network device sends a second downlink reference signal to the ue.

Step S302, the ue determines the carrier aggregation type in the frequency band according to the first downlink reference signal and the second downlink reference signal.

Wherein the intra-band carrier aggregation type is one of:

intra-band collocated (intra-band collocated) type;

intra-band non-collocated (intra-band non-collocated) type.

In some possible embodiments, the determining, by the user equipment, the intra-band carrier aggregation type according to the first downlink reference signal and the second downlink reference signal includes: determining the receiving power difference degree of the first downlink reference signal and the second downlink reference signal, and determining the carrier aggregation type in the frequency band based on the receiving power difference degree.

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

The difference degree of the received power of the first downlink reference signal and the received power of the second downlink reference signal is a difference value of 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 power difference can be referred to as Δ p, and the value of Δ p is p1-p 2.

Or the difference degree of the received power of the first downlink reference signal and the second downlink reference signal is the difference value 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 level can be referred to as Δ L, and the Δ L has values of L1-L2.

The power difference may be a 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 power difference can be referred to as p ', and the value of p' is (p1-p2)/p0, wherein p0 is a fixed value.

The power difference degree can also be other expressions which can embody the difference degree.

Wherein the set threshold is determined according to a protocol convention, or configuration information indicating the set threshold is received from the first network device.

In one example, the set threshold is a maximum tolerable value of a degree of difference in-band received power of a receiver of the user equipment.

And in response to the in-band carrier aggregation type being an in-band non-co-located type, sending maxNumberbERMIMO-LayersPDSCH-non-co-located to the first network device. The maxNumberbERMIMO-LayersPDSCH-noncolorated is used for indicating the maximum MIMO layer number corresponding to each carrier in non-co-located carrier aggregation in a frequency band.

Step S304, the first network equipment sends MIMO scheduling information configured based on the capability indication information to the user equipment.

In step S305, the user equipment performs MIMO processing according to the MIMO scheduling information.

In the embodiment of the disclosure, the user equipment determines the intra-band carrier aggregation type according to the downlink reference signals sent by the first network equipment and the second network equipment, and sends the capability indication information to the first network equipment to indicate the number of maximum multiple-input multiple-output (MIMO) layers supported by each component carrier corresponding to the corresponding intra-band carrier aggregation type, so that the first network equipment configures corresponding reasonable MIMO scheduling information according to the capability of the user equipment, and the utilization rate of wireless resources is improved.
