Detailed Description

The following description of the technical solutions in the embodiments of the present application will be made with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

The technical solution of the embodiment of the application can be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA) system, wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, general packet Radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) system, LTE frequency division duplex (Frequency Division Duplex, FDD) system, LTE time division duplex (Time Division Duplex, TDD) system, long term evolution advanced (Advanced long term evolution, LTE-a) system, new Radio (NR) system, evolution system of NR system, LTE (LTE-based access to unlicensed spectrum, LTE-U) system on unlicensed band, NR (NR-based access to unlicensed spectrum, NR-U) system on unlicensed band, universal mobile communication system (Universal Mobile Telecommunication System, UMTS), universal internet microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication system, wireless local area network (Wireless Local Area Networks, WLAN), wireless fidelity (Wireless Fidelity, wiFi), next generation communication system or other communication system, etc.

Generally, the number of connections supported by the conventional communication system is limited and easy to implement, however, with the development of communication technology, the mobile communication system will support not only conventional communication but also, for example, device-to-Device (D2D) communication, machine-to-machine (Machine to Machine, M2M) communication, machine type communication (Machine Type Communication, MTC), inter-vehicle (Vehicle to Vehicle, V2V) communication, and the like, to which the embodiments of the present application can also be applied.

Alternatively, the communication system in the embodiment of the present application may be applied in a scenario of carrier aggregation (Carrier Aggregation, CA), dual connectivity (Dual Connectivity, DC), independent (SA) networking, and the like.

Exemplary, a communication system 100 to which embodiments of the present application apply is shown in fig. 1. The wireless communication system 100 may include a network device 110. Network device 110 may be a device that communicates with a terminal device. Network device 110 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within the coverage area. Alternatively, the network device 100 may be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved base station (Evolutional Node B, eNB or eNodeB) in an LTE system, or a network-side device in an NR system, or a radio controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network-side device in a next generation network, or a network device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), or the like.

The wireless communication system 100 further includes at least one terminal device 120 located within the coverage area of the network device 110. The terminal device 120 may be mobile or stationary. Alternatively, the terminal device 120 may refer to an access terminal, user Equipment (UE), subscriber unit, subscriber station, mobile station, remote terminal, mobile device, user terminal, wireless communication device, user agent, or User Equipment. An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved PLMN, etc. Optionally, a direct terminal (D2D) communication may also be performed between the terminal devices 120.

Fig. 1 illustrates one network device and two terminal devices by way of example, and the wireless communication system 100 may alternatively include multiple network devices and may include other numbers of terminal devices within the coverage area of each network device, as embodiments of the present application are not limited in this regard. In addition, the wireless communication system 100 may further include other network entities such as a network controller, a mobility management entity, and the like, which is not limited in the embodiments of the present application.

The terminal device will typically have a variety of capabilities, which may include, for example, baseband capabilities, radio frequency capabilities, measurement capabilities, terminal class (category) capabilities, discontinuous resource allocation capabilities, group indication (featuregroup indicators, FGI) capabilities, support capabilities for various optional functions, and the like. Different terminal devices may have different capabilities, and after the terminal device accesses the network, the terminal device may send capability information of the terminal device to the network device, so that the network device may reasonably schedule the terminal device according to the capabilities supported by the terminal device. For example, the network device may allocate appropriate time-frequency resources, power, modulation coding schemes, and the like to the terminal device according to the capabilities supported by the terminal device.

Taking an NR system as an example, the baseband capability of the terminal device may include the capability of the terminal device to support different subcarrier widths, where the subcarrier width supported by the terminal device may be, for example, 7.5kHz, 15kHz, 30kHz or 60kHz, etc., and the uplink and downlink preparation time of the terminal device. The transmission parameters corresponding to different subcarrier widths may be different. The wider the subcarrier is, the shorter the corresponding symbol time is, the lower the time delay is, and the method can be suitable for scenes with higher time delay requirements; the narrower the subcarrier, the longer the corresponding symbol time, and the relatively higher the delay. The network device can reasonably schedule the terminal device according to the subcarrier width reported by the terminal device.

For example, when the network device schedules the terminal device, the network device may consider the subcarrier width supported by the terminal device, and when the subcarrier width of the terminal device is smaller, the network device may schedule according to the smaller subcarrier width. When the subcarrier width of the terminal device is larger, the network device may schedule the terminal device according to the larger subcarrier width.

The network device may schedule the terminal device according to the uplink and downlink preparation time of the terminal device, for example, when the network device schedules the uplink signal, the time interval for scheduling the uplink signal cannot be smaller than the uplink preparation time of the terminal device. When the uplink preparation time of the terminal equipment is smaller, the network equipment can schedule the uplink signal at smaller time intervals; when the uplink preparation time of the terminal device is larger, the network device can schedule the uplink signal at larger time intervals.

In LTE or NR systems, the radio frequency capability of a terminal device may include the supporting capability of the terminal device for different frequency band combinations, the number of transmit antennas of the terminal device, and so on. The network device may schedule the terminal device according to the radio frequency capabilities of the terminal device.

For example, if the number of antennas of the terminal device is 2, when the network device transmits data to the terminal device, the network device transmits data according to the receiving capability of 2 antennas, for example, the network device can transmit data to the terminal device at a smaller transmission rate; if the number of the antennas of the terminal device is 4, the network device will transmit according to the receiving capability of the 4 antennas when transmitting data to the terminal device, for example, the network device can transmit data to the terminal device at a larger transmission rate.

For another example, if the terminal device has the capability to support carrier aggregation (carrier aggregation, CA), the network device may schedule the terminal device according to the capability to support CA to promote the data transmission rate.

Optional capabilities of the terminal device may include, for example, a global subscriber identity card (universal subscriber identity module, USIM) application toolbox (USIM application toolkit, USAT), and USAT technology is the capability of adding new active operation of the SIM card based on the original passive operation mode of the SIM card, i.e. to allow applications in the SIM card to actively interoperate with the terminal device. For optional capabilities, the terminal device needs to report to the network device whether the terminal device supports the optional capabilities when reporting to the network device. For example, if the terminal device supports USAT technology, it needs to report to the network device that it supports USAT technology; if it does not support USAT technology, it needs to report to the network device that it does not support USAT technology.

After the terminal device accesses the network, the terminal device reports the capability information of the terminal device to the network device in the signaling of the capability (capability) of the UE. Typically, the capabilities of the terminal device, such as baseband capabilities, radio frequency capabilities, etc., are fixed after the terminal device is manufactured, with the highest capabilities supported by the terminal device. The baseband capability of the terminal device depends on the baseband modem unit (modem) selected by the terminal device, and after the terminal device leaves the factory, the modem is fixed, and therefore, the baseband capability of the terminal device is fixed. The radio frequency capability of the terminal device depends on the design of the radio frequency/antenna of the terminal device, so that the radio frequency capability of the terminal device is also fixed after the shipment of the terminal device.

The capabilities of the terminal device may include mandatory and optional capabilities, which may be referred to as capability characteristics of the terminal device. In current wireless systems, such as LTE or NR systems, the capability characteristics of the terminal device may be mandatory or optional. When a certain capability is an optional capability, it means that the terminal device must support this capability. When a certain capability is an optional capability, the terminal device may or may not support the capability, but when reporting UE capability to the network device, the terminal device needs to report whether it supports the optional capability to the network device.

However, whether an optional capability or a necessary capability, when a terminal device is manufactured, its corresponding capability is already determined and cured, and no capability change occurs due to the use of the terminal device. For example, if a terminal device is manufactured without supporting millimeter wave characteristics, the terminal device will not always support the millimeter wave characteristics during subsequent use. If the terminal device has a receiving capability of 4 antennas after manufacture, the receiving capability of the terminal device will not change in the subsequent use process, namely, the receiving capability of 4 antennas.

Therefore, when reporting the capability to the network device, the terminal device needs to report the necessary capability and the optional capability to the network device. Because the optional capability and the necessary capability of the terminal device are fixed after the terminal device is manufactured, after the terminal device reports the UE capability to the network device, the network device can schedule the terminal device according to the capability of the terminal device reported in the UE capability when the network device schedules the terminal device subsequently, so as to realize correct communication between the terminal device and the network device.

However, with the development of technology, various forms of terminal devices may occur in the future, such as the baseband capability and/or the radio frequency capability of the terminal device are not fixed, and they may change according to the usage situation after the terminal device is manufactured.

As an example, as materials and processes progress, various new forms or structures of terminal devices, such as mobile phones, in which a screen or a body can be folded or bent, have been developed. The number of antennas supported by the handset is different when the handset is in the folded and unfolded state. For example, when the mobile phone is in an unfolded state, the number of effective receiving antennas of the mobile phone is 8, and when the screen or body of the mobile phone is in a folded or bent state, the number of effective receiving antennas of the mobile phone may be reduced to 4, because a certain interval is required between the antennas of the mobile phone to ensure the receiving/transmitting performance, and when the screen of the mobile phone is in a folded state, the number of effective antennas which can be accommodated in space may be smaller than that when the mobile phone is in an unfolded state. Therefore, the number of effective receiving antennas of the mobile phone in the folded state is smaller than that in the unfolded state. When the handset is in a folded state, the network device may need to send data to the terminal device according to the reception capability of the 4 antennas. In this case, the folded state of the body or screen of the mobile phone determines the number of antennas of effective transmission/reception of the mobile phone.

As another example, with the development of random technology, various modules may appear that may be external/external to the handset. Such as millimeter wave communication modules. Millimeter wave communication may refer to communication with millimeter waves as a carrier for transmitting information. The millimeter wave frequency band is generally 30 GHz-300 GHz, which can also be called FR2 frequency band, and the corresponding wavelength is 1 mm-10 mm. Because millimeter waves are in a higher frequency band and have fewer interference sources, the propagation is stable and reliable, and therefore millimeter wave communication is a typical communication technology with a high-quality and constant-parameter wireless transmission channel. In addition, millimeter waves have stronger penetration capability to sand dust and smog. Thus, millimeter wave communication has a good development prospect.

For terminal devices supporting millimeter wave communication, it may support the capability to include any FR2 related baseband processing, e.g., the terminal device may support higher subcarrier spacing (subcarrier spacing, SCS), such as 120kHz SCS,240 kHz SCS, etc. The larger SCS can resist larger Doppler shift, is suitable for high-speed moving scenes, and the larger SCS has shorter symbol length and is suitable for low-delay scenes.

However, for NR handsets, if the current millimeter wave communication modules, such as FR 2-enabled radio frequency and antenna modules, are integrated into the handset, a significant amount of internal space is occupied. One possible solution is to make the millimeter wave communication module an external module, which can be connected to a mobile phone when millimeter wave communication is required. In this case, when the mobile phone has no external millimeter wave communication module, the mobile phone is actually free from millimeter wave communication capability. When the mobile phone is externally connected with the millimeter wave communication module, the mobile phone has the capability of supporting millimeter wave communication. Millimeter wave communication capabilities may include any baseband processing associated with FR2, such as support for 120k SCS,240k SCS, etc., and any support for the frequency bands and associated characteristics of FR2, etc. For example, for characteristics such as physical downlink shared channel (physical downlink shared channel, PDSCH) wave number scan (beam switch), or what is called downlink data channel wave number scan, only terminal devices supporting the FR2 band need to support.

Therefore, some baseband capability, radio frequency capability or other capability of the mobile phone may change correspondingly according to different usage states of the mobile phone after the mobile phone leaves the factory, and the embodiment of the application can change the capability of the terminal device into a variable capability. For example, if the support of millimeter waves by the terminal device is a variable capability, that means that the terminal device may sometimes support millimeter wave communication during subsequent use, and sometimes not support millimeter wave communication. As another example, if the number of antennas supported by the terminal device is a variable capability, that means that the number of antennas supported by the terminal device may change during subsequent use, in other words, the receiving/transmitting capability of the terminal device may change. The variable capability of the terminal equipment cannot be realized by adopting the existing definition method of the terminal capability. After reporting the capability of the UE to the network device, the network device cannot schedule the terminal device according to the capability of the UE, which may cause defects such as unreasonable scheduling of the terminal device and influence on user experience.

For the variable capability, when the network device schedules the terminal device, the current capability information of the terminal device needs to be known timely, so as to reasonably schedule the terminal device. Therefore, how to report capability information to the network device by the terminal device becomes a problem to be solved.

The embodiment of the application provides a method for transmitting capability information, which can realize reasonable scheduling of network equipment to terminal equipment. The method for transmitting the capability information in the embodiment of the application can be applied to various communication systems, such as an NR system or an LTE system. As shown in fig. 2, the method includes step 210.

S210, the terminal equipment sends first information to the network equipment, wherein the first information is used for indicating that the first capability of the terminal equipment is variable capability.

The first information may be carried in UE capability, and the terminal device may send the UE capability to the network device, and indicate, in the UE capability, that the first capability of the terminal device is a variable capability through the first information.

For example, the terminal device and the network device may define in advance which fields in the UE capability are variable capabilities of the terminal device, and the terminal device writes the variable capabilities into corresponding fields when sending the UE capability to the network device. Thus, the network device can determine the variable capability of the terminal device according to the different fields after receiving the UE capability. As another example, the terminal device may also indicate which capabilities are variable capabilities in a bit manner. For example, a 2bit may be used to indicate the capability characteristics of the terminal device, e.g., "00" may be used to indicate the mandatory capability of the terminal device, "01" may be used to indicate the optional capability of the terminal device, and "10" may be used to indicate the variable capability of the terminal device. The manner of indicating the capability characteristics of the terminal device using the 2bit is not limited to the above description, and other indication manners may be used, such as using "00" to indicate the variable capability of the terminal device, using "01" to indicate the necessary capability of the terminal device, using "10" to indicate the optional capability of the terminal device, and so on.

The first information may also be indication information, and the terminal device may send indication information to the network device, for indicating that the first capability in the terminal device is a variable capability.

The first information may also indicate the variable capability of the terminal device in other manners, which are not specifically limited in the embodiments of the present application.

The capacity may be divided in different manners, for example, the capacity may be divided according to a coarser granularity, and the capacity may be divided into baseband capacity, radio frequency capacity, and the like. For another example, the capability may also be divided at a finer granularity, such as dividing the capability into supported subcarrier spacing, the number of receive antennas, and so on. The first capability may be differently understood in different divisions. The first capability is not specifically limited in the embodiments of the present application.

For example, the first capability may refer to a type of capability of the terminal device, e.g., the first capability may be a baseband capability or a radio frequency capability. The first information may indicate that the baseband capability in the terminal device is a variable capability, or the first information may indicate that the radio frequency capability in the terminal device is a variable capability. As another example, the first capability may refer to a class of capabilities that are important to the current scheduling of the network device.

For another example, the first capability may also be a specific capability in the terminal device, e.g. the first capability may be the number of supported receive antennas, or the first capability may be a supported subcarrier spacing, etc.

The terminal device may report all the variable capabilities to the network device. The terminal device may use the same information to indicate the plurality of variable capabilities when reporting the plurality of variable capabilities to the network device, e.g. may use the first information to indicate the plurality of variable capabilities. Alternatively, the terminal device may indicate the plurality of variable capabilities with different information, for example, may indicate the plurality of variable capabilities with a plurality of information, respectively.

The terminal device may send first information to the network device, which may indicate the capabilities of the terminal device and the capability characteristics of the capabilities. For example, the terminal device may send first information to the network device, the first information including the number of antennas supported by the terminal device and a capability characteristic corresponding to the number of antennas.

The indication manner of the capability characteristic by the terminal device may be indicated in a bit manner, and the capability characteristic may include optional capability, necessary capability and variable capability. For example, the terminal device may indicate the capability characteristics using 2-bit bits. If "00" is used to represent the optional capability of the terminal device, "01" is used to represent the optional capability of the terminal device, and "10" is used to represent the variable capability of the terminal device. The terminal device may report capability information to the network device in a "capability+capability feature" manner. When the first information transmitted from the terminal device to the network device includes "the number of antennas, 10", it means that the number of antennas supported by the terminal device is a variable capability.

Optionally, the terminal device may further send second information to the network device, where the second information is used to indicate the capability before the first capability update. The terminal device may indicate to the network device, in addition to indicating to the network device which capabilities are variable capabilities, the capability information of the variable capabilities that are currently available, so that the network device may advantageously schedule the terminal device according to the capability information of the terminal device that is currently available.

The second information and the first information may be the same or different. The terminal device may directly report the capability, the capability characteristic, and the current capability information to the network device using the first information. Alternatively, the terminal device only reports to the network device in the first information which capabilities are variable capabilities, which capabilities are optional capabilities and/or which capabilities are mandatory capabilities. And then sending second information to the network device, and indicating the capability information of the variable capability to the network device.

Of course, the network device may also employ a plurality of pieces of information to indicate capability information of a plurality of variable capabilities to the network device, respectively.

The reporting mode of the terminal device is not particularly limited in the embodiment of the application. Taking the terminal device as an example, the terminal device indicates the capability, the capability characteristic and the capability information by using the first information, the terminal device may report to the network device by using the mode of "capability+capability characteristic+capability information", taking the number of antennas supported by the terminal device as a variable capability as an example, the terminal device may send the first information to the network device, where the first information may include "the number of antennas, 10, 100", where "100" indicates that the number of antennas currently supported by the terminal device is 4.

The first capabilities of the terminal device described above may comprise baseband capabilities and/or radio frequency capabilities of the terminal device, etc. The baseband capability may include the subcarrier width supported by the terminal equipment. The radio frequency capability may include the number of transmit/receive antennas of the terminal device, etc.

The capability information may change during use of the terminal device. In this case, the terminal device may send updated capability information to the network device after the capability update occurs. In other words, after the first capability is updated, the terminal device indicates the updated first capability to the network device. For example, the terminal device may send a UE capability update (update) to the network device to indicate the updated capability.

The terminal device may report the updated capability to the network device after the capability information is updated, in other words, the terminal device may report only the related information of the updated capability to the network device after the capability information is updated, and those capabilities which are not updated or are not changeable may not need to report to the network device, which may save a certain signaling overhead. Thus, the network equipment can timely know that the capacity of the terminal equipment is updated, and schedule the terminal equipment according to the updated capacity.

The capability information described above may include whether the capability is supported, the size of the capability, or some type of the capability.

The updating of the capability may include an update of whether the variable capability is supported, e.g., supported update to unsupported, or unsupported update to supported. The update of the capability may also include an update of the variable capability size, for example the number of antennas, which may be changed from 4 to 8, etc. The updating of the capability may also include some type of switching of the variable capability, such as switching from an a-capability to a B-capability, for example, a transmission capability that may be updated from supporting millimeter wave communication to supporting millimeter wave communication, etc.

Taking the variable capability as millimeter wave communication as an example, if the terminal device does not support millimeter wave communication when reporting UE capability to the network device, reporting the capability before update to the network device by the terminal device may mean that the terminal device does not support millimeter wave communication to the network device. If the terminal device changes the capability to support millimeter wave communication in the subsequent use process, the terminal device reports the updated capability to the network device, and the updated capability can point to the network device to report the updated capability as supporting millimeter wave communication.

Taking the variable capability as the number of receiving antennas as an example, if the number of antennas supported by the terminal device is 4 when reporting UE capability to the network device, the capability before reporting the update to the network device by the terminal device may refer to that the number of receiving antennas supported by the terminal device to the network device is 4. If the number of the receiving antennas becomes 8 in the subsequent use process of the terminal device, the capability of reporting the updated receiving antennas to the network device by the terminal device may mean that the number of the receiving antennas after reporting the updated is 8.

Taking the variable capability as the transmission capability as an example, if the transmission capability supported by the terminal device is millimeter wave communication support when reporting UE capability to the network device, reporting the capability before update to the network device by the terminal device may refer to reporting millimeter wave communication support to the network device. If the transmission capability of the terminal device becomes to support the micro-wave communication in the subsequent use process, the capability of the terminal device reporting the updated capability to the network device may refer to reporting the updated transmission capability as supporting the micro-wave communication.

Of course, the terminal device may report all the capability information to the network device again according to the reporting mode in the capability of the UE, which is not specifically limited in the embodiment of the present application.

Assuming that two capabilities of the terminal device are updated, the terminal device may indicate the two updated capabilities to the network device together, e.g. the terminal device may send the two updated capability information bearers to the network device in a signaling. Alternatively, the terminal device may also indicate the two updated capability information, respectively. For example, the terminal device may use 2 signaling to carry the two updated capability information respectively.

The manner in which the terminal device indicates the updated first capability is not specifically limited in the embodiment of the present application.

As one example, the updated information of the first capability may be carried on radio resource control (radio resource control, RRC) RRC signaling. When the terminal device reports the capability information to the network device, the capability information may be reported to the network device through UE capability, and the UE capability signaling may be RRC signaling. Therefore, the terminal device may also report the updated capability information to the network device using RRC signaling. For example, the terminal device may carry UE capability update signaling over RRC signaling, indicating updated capability information to the network device.

When the terminal device has multiple variable capability updates, the terminal device may carry the multiple updated capability information on an RRC signaling and send the multiple updated capability information to the network device. Alternatively, the terminal device may send a plurality of RRC signaling to the network device, each RRC signaling carrying one updated capability information.

As yet another example, the updated first capability may be carried on media access control (media access control, MAC) signaling. When the terminal device reports the capability information to the network device, the capability information may be reported to the network device through UE capability, and the UE capability signaling may be MAC signaling.

Alternatively, a new MAC signaling may be defined in the protocol and used to transmit updated capability information. After the capability is updated, the terminal device uses the newly defined MAC signaling to transmit updated capability information.

When the terminal device has multiple variable capability updates, the terminal device may carry the multiple updated capability information on one MAC signaling and send the multiple updated capability information to the network device. Alternatively, the terminal device may send a plurality of MAC signaling to the network device, each MAC signaling carrying one updated capability information.

Since the MAC layer is located at a lower layer of the RRC layer, the terminal device transmits MAC signaling to the network device faster than RRC signaling. The time required from the terminal equipment sending the MAC signaling to the network equipment receiving the MAC signaling is smaller than the time required from the terminal equipment sending the RRC signaling to the network equipment receiving the RRC signaling, so that the terminal equipment adopts the MAC signaling to report the updated capability information, the network equipment can obtain the updated capability of the terminal equipment more quickly, the scheduling of the terminal equipment can be adjusted quickly, and the user experience is improved.

As yet another example, the updated information of the first capability may be carried on a physical layer channel. The network device may allocate some physical layer channel resources to the terminal device in advance so that the terminal device indicates updated capabilities using the physical layer channel resources. Compared with MAC signaling and RRC signaling, the physical layer channel has higher transmission speed, and for the capability of immediately influencing the scheduling of the network equipment, the physical layer channel is adopted for transmission, so that the network equipment can immediately adjust the scheduling and the user experience is improved.

After some variable capability of the terminal device is changed, it is important for the current scheduling of the network device. Thus, for these variable capabilities, the network device needs to know updated information of these capabilities in a timely manner.

Taking the foldable screen described above as an example, the number of receiving antennas of the terminal device is the variable capability of the terminal device. When the number of terminal device transmitting/receiving antennas changes as the terminal device screen/body is folded, it is important for the network device to know the change in time. For example, when the screen is folded, the terminal device has 4 receiving antennas, or called receiving ports; and when the screen is completely opened, the number of receiving antennas of the terminal device may become 8.

When the screen is changed from the folded state to the fully opened state while the user is watching the video, the user can watch the video using a larger screen, and accordingly, the video download rate needs to be increased accordingly. When the network device can timely learn that the number of the receiving antennas of the terminal device is changed from 4 to 8, the receiving capability of the terminal device is improved, and the terminal device can receive data by adopting 8 receiving antennas. Therefore, the network device may use more multiple-input multiple-output (MIMO) streams (streams), or higher modulation and coding strategy (modulation and coding scheme, MCS) levels to increase the download rate, so as to increase the utilization of network resources and improve the user experience.

Therefore, it is important that the network device be aware of this change in time. If the speed of reporting the change of the capability to the network device by the terminal device is slower, the time required from the terminal device to the network device receiving the updated capability is too long, the network device cannot timely adjust the scheduling of the terminal device, and the terminal device cannot timely adopt more antennas to receive the data, which may affect the smoothness of viewing the video and affect the user experience.

Compared with RRC signaling and MAC signaling, the physical layer channel has a relatively faster transmission speed, i.e. the time from the capability of the terminal equipment after update to the capability of the network equipment after update is received is shorter, therefore, for the terminal capability important for the current scheduling of the network equipment, the capability of the physical layer channel after update is adopted to be beneficial to the network equipment to immediately adjust the scheduling of the terminal equipment, and the user experience is improved.

The physical layer channels may include, for example, a physical uplink control channel (physical uplink control channel, PUCCH) or a physical uplink shared channel (physical uplink shared channel, PUSCH), etc. Taking PUCCH as an example, the network device may allocate PUCCH resources to the terminal device in advance. When the capability of the terminal equipment is updated, the terminal equipment can report the updated capability to the network equipment by adopting the PUCCH resource.

Alternatively, the network device may allocate a physical layer channel resource to the terminal device. After any variable capability of the terminal equipment is updated, the updated capability is indicated to the network equipment by adopting the physical layer channel resource.

Alternatively, the network device may also allocate a plurality of physical layer channel resources to the terminal device in advance, where the plurality of physical layer channel resources have a mapping relationship with the variable capability of the terminal device. The network device may allocate different physical layer channel resources for different variable capabilities, in other words, when the terminal device reports the updated capability, the updated different first capability information may be carried on the different physical layer channel resources. In this way, the network device can determine which of the variable capabilities of the terminal device have been updated based on the received information of the physical layer channel resources.

For example, taking physical layer channel resources as PUCCH, the variable capability of the terminal device includes variable capability 1 and variable capability 2. The network device may allocate 2 PUCCH resources, PUCCH resource 1 and PUCCH resource 2, to the terminal device in advance, and configure a resource corresponding to the variable capability 1 as PUCCH resource 1, and a resource corresponding to the variable capability 2 as PUCCH resource 2.

When the variable capability 1 of the terminal device changes, the terminal device may use PUCCH resource 1 to indicate its updated capability to the network device. When the variable capability 2 of the terminal device changes, the terminal device may use the PUCCH resource 2 to indicate its updated capability to the network device. Since there is a mapping relationship between the PUCCH resource and the variable capability of the terminal device, if the network device receives the updated capability sent by the terminal device on the PUCCH resource 1, it can be determined that the variable capability 1 of the terminal device has changed. If the network device receives the updated capability sent by the terminal device on PUCCH resource 2, the network device may determine that the variable capability 2 of the terminal device has changed.

When the terminal device transmits the updated capability, only the updated capability information may be transmitted. For example, if the variable capability 1 is the number of transmit/receive antennas, the terminal device may send only the updated number of antennas on the PUCCH resource 1, for example, send "1000" on the PUCCH resource, and after the network device receives the information on the PUCCH resource 1, it may determine that the number of transmit/receive antennas of the terminal device is updated to 8 according to the correspondence between the PUCCH resource and the variable capability of the terminal device, and the foregoing manner of sending only the updated capability information can save signaling overhead.

Of course, the terminal device may also indicate the variable capability to the network device together with the updated capability information. For example, the terminal device may send the information of "number of antennas, 1000" on the PUCCH resource 1, so that after receiving the information, the network device may directly determine that the number of antennas after updating by the terminal device becomes 8 without checking the mapping relationship between the PUCCH resource and the variable capability of the terminal device.

When the terminal device indicates the updated capability on the PUCCH resource, the terminal device may indicate in different formats according to the specific capability.

As an example, if the maximum number of antennas supported by the terminal device is 8, reporting the updated number of antennas by the terminal device may be indicated by using 4 bits. For example, if the number of antennas updated by the terminal device is 4, the terminal device may send indication information of "0100" to the network device; if the number of antennas updated by the terminal device is 8, the terminal device may send an indication of "1000" to the network device.

As another example, for a terminal device variable capability of whether to support millimeter wave communication, the terminal device reporting updated capability may be indicated with a 1 bit. For example, when the bit has a value of "1", it indicates that the capability information updated by the terminal device is for supporting millimeter wave communication; when the bit has a value of "1", it indicates that the capability information updated by the terminal device is not supporting millimeter wave communication.

The above is merely an example, and other indication manners may be used by the terminal device to indicate the updated capability to the network device. The embodiment of the present application is not particularly limited thereto.

The method for the terminal device to acquire the PUCCH resource in the embodiment of the present application is not specifically limited. For example, PUCCH resources used by the variable capability may be specified in a protocol. For another example, the terminal device may negotiate PUCCH resources used by the variable capability with the network device in advance, and a mapping relationship between the PUCCH resources and the variable capability. The network device may configure PUCCH resource information corresponding to the variable capability to the terminal device through higher layer signaling and/or RRC signaling in advance.

When the terminal device reports the updated capability to the network device, the terminal device may also report the updated capability by adopting a combination of the above-described modes in addition to the above-described modes.

For example, the PUCCH may carry information of the updated first capability, and the RRC signaling or the MAC signaling may carry information of the updated first capability and information of the updated second capability, which is a variable capability. The first capability may be a capability that can have an immediate impact on the network device's scheduling, and the second capability may be some capability that is not important to the network device's current scheduling. For variable capabilities that may have an immediate impact on network device scheduling, reporting to the network device may be performed as soon as possible through physical layer signaling, e.g., reporting to the network device through PUCCH. However, after reporting the updated capability through the PUCCH, the terminal device may further report complete variable capability update information including variable capability update information transmitted on the PUCCH and variable capability update information not transmitted on the PUCCH to the network device in RRC signaling or MAC signaling.

For ease of description, the variable capabilities that will immediately impact network device scheduling may be referred to as a first type of variable capability, and the other variable capabilities may be referred to as a second type of variable capability.

The terminal device can report the updated first type variable capability on the PUCCH, so that the network device can adjust the scheduling of the terminal device according to the updated information of the first type variable capability in time. In addition, when reporting the updated second type variable capability to the network device through RRC signaling or MAC signaling, the terminal device may report the first type variable capability to the network device again. In this way, the network device can be effectively guaranteed to receive updated first-class variable capabilities.

Of course, in addition to the baseband capability and the radio frequency capability described above, other capabilities of the terminal device may become variable capabilities as technology advances, and embodiments of the present application are not limited in this regard.
