Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0002] In order to increase the transmission bandwidth and meet the requirements of users to increase the peak rate, existing terminal devices can already support access to multiple component carriers (CCs) to increase the transmission bandwidth, such as carrier aggregation (CA) and dual-connectivity (DC) scenarios of terminal devices. At the same time, since the out-of-band interference of millimeter wave (FR2) is small, in order to reduce the power consumption of terminal devices, one transceiver channel can be used to support the transceiver of multiple CCs configured by the network device for the terminal device. In addition, due to the high operating frequency, rich spectrum resources, and the introduction of beamforming and large bandwidth of FR2, the power consumption of terminal devices is relatively large. The design of the transmitter and receiver sharing the local oscillator (LO) can be adopted in the (radio frequency, RF) design, that is, the uplink channel (transmit) and the downlink channel (receive) of the transceiver channel supporting the transceiver of multiple CCs share the LO, and the LO position is consistent for all uplink and downlink CCs, thereby reducing the power consumption of the phase locked loop (PLL) to the terminal device.

[0003] For the architecture design in which multiple CCs use one transceiver channel for transceiver transmission, the terminal device needs to report a frequency span level that a transceiver channel can support to the network device so that the network device can configure the operating frequency and bandwidth of the uplink CC and downlink CC for the terminal device. Since the frequency span level of the terminal device in uplink and downlink is not only related to RF, but also to baseband (BB), when the bandwidth supported by the RF and / or BB of the transceiver channel is different in uplink and downlink, the uplink frequency span level and downlink frequency span level supported by the transceiver channel will also be different. Therefore, the existing protocol defines that the terminal device reports the frequency span level separately in uplink and downlink.

[0004] However, the protocol does not stipulate that the bandwidth and center frequency of the uplink CC and downlink CC configured by the network device for the terminal device must be consistent. The bandwidth and center frequency of the uplink CC and downlink CC are configured by the network device for the terminal device respectively and are not related to each other. Therefore, the bandwidth and center frequency of the uplink CC and downlink CC are likely to be configured differently. Since the transmitting and receiving channels share LO, this will result in the overall frequency span including the uplink CC and downlink CC configured by the network device for the terminal device, which exceeds the uplink maximum frequency span and downlink maximum frequency span indicated by the uplink frequency span level and downlink frequency span level reported by the terminal device, resulting in a mismatch between the capabilities reported by the terminal device and the configuration sent by the network device. Summary of the invention

[0005] The present application provides a communication method and apparatus to solve the problem in the prior art that the capability reported by the terminal device is incomplete, resulting in a mismatch between the capability reported by the terminal device and the configuration sent by the network device.

[0006] In a first aspect, an embodiment of the present application provides a communication method, the method comprising: a terminal device generates capability information, the capability information comprising an overall frequency span level of the terminal device, the overall frequency span level being used to indicate a maximum frequency span between a lowest component carrier and a highest component carrier including an uplink component carrier and a downlink component carrier supported by the terminal device; and the terminal device sends the capability information to a network device.

[0007] The communication method implemented by the terminal device described in the embodiment of the present application may also be implemented by components of the terminal device, such as processing chips, circuits and other components in the terminal device. With the above method, the capability information sent / reported by the terminal device to the network device includes an overall frequency span level for indicating the maximum frequency span between the lowest component carrier and the highest component carrier including the uplink component carrier and the downlink component carrier supported by the terminal device, thereby avoiding the problem that the network device configures the uplink component carrier and the downlink component carrier for the terminal device only according to the uplink frequency span level and the downlink frequency span level of the terminal device, resulting in the overall frequency span of the uplink component carrier and the downlink component carrier exceeding the uplink maximum frequency span and the downlink maximum frequency span indicated by the uplink frequency span level and the downlink frequency span level, and the terminal device cannot support the problem, thereby avoiding the problem of mismatch between the capabilities reported by the terminal device and the configuration sent by the network device.

[0008] In a possible design, the capability information further includes: terminal device type indication information, the terminal device type indication information includes a first terminal device type identifier or a second terminal device type identifier, the first terminal device type identifier is used to indicate that the uplink frequency span level and the downlink frequency span level of the terminal device are the same; the second terminal device type identifier is used to indicate that the uplink frequency span level and the downlink frequency span level of the terminal device are different. In the above design, the terminal type indication information is introduced into the capability information to indicate whether the uplink frequency span level and the downlink frequency span level of the terminal device are the same. When the uplink frequency span level and the downlink frequency span level of the terminal device are the same, the uplink frequency span level and the downlink frequency span level of the terminal device are the same as the overall frequency span level of the terminal device, and the uplink frequency span level and the downlink frequency span level of the terminal device may not be included in the capability information, thereby saving signaling overhead.

[0009] In one possible design, when the terminal device type indication information includes a second terminal device type identifier, the capability information further includes: an uplink frequency span level and a downlink frequency span level of the terminal device. In the above design, when the uplink frequency span level and the downlink frequency span level of the terminal device are different from the overall frequency span level of the terminal device, the terminal device sends the uplink frequency span level and the downlink frequency span level of the terminal device to the network device through the capability information, so as to ensure that the network device accurately configures the uplink component carrier and the downlink component carrier for the terminal device.

[0010] In one possible design, the uplink component carrier and the downlink component carrier supported by the terminal device are located on a frequency band combination composed of one or more bands. In the above design, the overall frequency span level of the terminal device, as well as the uplink frequency span level and the downlink frequency span level can be reported for uplink component carriers and downlink component carriers located in the same frequency band (intra band) or different frequency bands (inter band), which expands the scope of application of the communication method, further avoids the problem that the overall frequency span of the uplink component carrier and the downlink component carrier configured by the network device for the terminal device exceeds the uplink maximum frequency span and the downlink maximum frequency span indicated by the uplink frequency span level and the downlink frequency span level, and the terminal device cannot support it, and ensures that the capabilities reported by the terminal device match the configuration sent by the network device.

[0011] In one possible design, the terminal device generates capability information, including: the terminal device generates one or more capability information corresponding to one or more transceiver channels for one or more transceiver channels. In the above design, when the frequency spectrum span of intra band CA / DC and inter band CA / DC increases and the terminal device cannot support it through one transceiver channel, the terminal device can report the capability information of multiple transceiver channels to the network device, and support intra band CA / DC and inter band CA / DC with a larger frequency span through multiple transceiver channels, thereby expanding the communication capability between the terminal device and the network device.

Using the above method, the terminal device can report the uplink frequency span level and downlink frequency span level of multiple bands as a whole according to the frequency band combination granularity. For example, in the inter-band CA scenario, the network device can report the uplink frequency span level and downlink frequency span level of multiple bands as a whole, which saves signaling overhead and enriches the way of reporting capability information.

[0014] In one possible design, the terminal device generates capability information, including: the terminal device generates one or more capability information corresponding to the one or more transceiver channels for the one or more transceiver channels. In the above design, when the spectrum span of inter-band CA / DC, etc. increases and the terminal device cannot support it through one transceiver channel, the terminal device can report the capability information of multiple transceiver channels to the network device, and support inter-band CA / DC, etc. with a larger frequency span through multiple transceiver channels, thereby expanding the communication capability between the terminal device and the network device.

[0015] In a third aspect, an embodiment of the present application provides a communication method, the method comprising: a network device receives capability information sent by a terminal device, the capability information comprising an overall frequency span level of the terminal device, the overall frequency span level being used to indicate a maximum frequency span between a lowest component carrier and a highest component carrier including an uplink component carrier and a downlink component carrier supported by the terminal device; the network device configures an uplink component carrier and a downlink component carrier for the terminal device according to the capability information.

[0016] The communication method implemented by the network device described in the embodiment of the present application may also be implemented by components of the network device, such as processing chips, circuits and other components in the network device. With the above method, the capability information sent / reported by the terminal device to the network device includes overall frequency span information for indicating the maximum frequency span between the lowest component carrier and the highest component carrier including the uplink component carrier and the downlink component carrier supported by the terminal device, thereby avoiding the problem that the network device configures the uplink component carrier and the downlink component carrier for the terminal device only according to the uplink frequency span level and the downlink frequency span level of the terminal device, resulting in the overall frequency span of the uplink component carrier and the downlink component carrier exceeding the uplink maximum frequency span and the downlink maximum frequency span indicated by the uplink frequency span level and the downlink frequency span level, and the terminal device cannot support the problem, thereby avoiding the problem of mismatch between the capabilities reported by the terminal device and the configuration sent by the network device.

In the above design, the terminal type indication information is introduced into the capability information to indicate whether the uplink frequency span level and the downlink frequency span level of the terminal device are the same. When the uplink frequency span level and the downlink frequency span level of the terminal device are the same, the uplink frequency span level and the downlink frequency span level of the terminal device are the same as the overall frequency span level of the terminal device, and the uplink frequency span level and the downlink frequency span level of the terminal device may not be included in the capability information, thereby saving signaling overhead.

[0053] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0054] The technical solutions of the embodiments of the present application can be applied to various communication systems, for example, the fifth generation (5G) communication system, the long term evolution-advanced (LTE-A) system and other communication systems, and can also be extended to related cellular systems such as wireless fidelity (WiFi), worldwide interoperability for microwave access (WiMAX), and future communication systems such as 6G systems. It can be applied to CA scenarios, DC scenarios, etc. The communication system architecture used in the embodiments of the present application can be as follows: Figure 1As shown, it includes at least one network device and a terminal device, Figure 1 Take three network devices as an example. Each network device may have one or more carriers, and each carrier usually corresponds to a cell. The terminal device may access multiple carriers of the same network device, or multiple carriers of different network devices. When the terminal device accesses multiple carriers, each carrier accessed by the terminal device is a CC accessed by the terminal device.

[0055] Example: See Figure 2A As shown, carrier F1 and carrier F2 share the same site and coverage (they are carriers possessed by the same network device, and the coverage range is the same or approximately the same), carrier F1 and carrier F2 may be in the same frequency band, and the terminal device can simultaneously access carrier F1 and carrier F2 in the area where the coverage range of carrier F1 and carrier F2 overlaps. Carrier F1 and carrier F2 serve as CCs accessed by the terminal device.

[0056] See also Figure 2B and Figure 2C As shown, carrier F1 and carrier F2 are co-located with different coverage (they are carriers possessed by the same network device, and their coverage ranges overlap). Carrier F1 and carrier F2 may be in different bands. Terminal devices can simultaneously access carrier F1 and carrier F2 in the area where the coverage ranges of carrier F1 and carrier F2 overlap. Carrier F1 and carrier F2 serve as CCs accessed by terminal devices.

[0057] See also Figure 2D As shown, carrier F1 and carrier F2 do not share the same site or coverage (they belong to different network devices, and have the same or approximately the same coverage range). For example, carrier F1 and carrier F2 may belong to network device X and network device Y, respectively. The terminal device may simultaneously access carrier F1 and carrier F2 in the area where the coverage ranges of carrier F1 and carrier F2 overlap. Carrier F1 and carrier F2 serve as CCs accessed by the terminal device to achieve dual connection to network device X and network device Y.

[0058] Above Figure 2A-2D This is only an example of a scenario in which a terminal device accesses multiple CCs. It should be understood that the embodiments of the present application can also be applied to scenarios in which other terminal devices access multiple CCs.

[0059] Before introducing the embodiments of the present application, some terms in the present application are first explained to facilitate understanding by those skilled in the art.

[0060] 1) Terminal equipment, including equipment that provides voice and / or data connectivity to users, such as a handheld device with wireless connection function, or a processing device connected to a wireless modem. The terminal equipment can communicate with the core network via a radio access network (RAN) and exchange voice and / or data with the RAN. The terminal equipment may include user equipment (UE), wireless terminal equipment, mobile terminal equipment, device-to-device (D2D) terminal equipment, V2X terminal equipment, machine-to-machine / machine-type communications (M2M / MTC) terminal equipment, Internet of Things (IoT) terminal equipment, subscriber unit, subscriber station, mobile station, remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, or user equipment, etc. For example, it may include mobile phones (or "cellular" phones), computers with mobile terminal devices, portable, pocket-sized, handheld, and computer-built-in mobile devices, etc. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDA), and other devices. It also includes limited devices, such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power, etc. For example, it includes information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning systems (GPS), laser scanners, etc.

[0061] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as wearable smart devices or smart wearable devices, etc., which are a general term for the application of wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-size, and independent of smartphones to achieve complete or partial functions, such as smart watches or smart glasses, etc., as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets, smart helmets, and smart jewelry for vital sign monitoring.

[0062] The various terminal devices introduced above, if located on a vehicle (eg, placed in or installed in a vehicle), can be considered as vehicle-mounted terminal devices, which are also called on-board units (OBU).

[0063] In the embodiment of the present application, the terminal device may also include a relay. Alternatively, it can be understood that anything that can communicate data with the base station can be regarded as a terminal device.

[0064] 2) Network equipment, which may refer to equipment in an access network that communicates with a wireless terminal device through one or more cells at an air interface. The network equipment may be a node in a wireless access network, which may also be referred to as a base station, or a radio access network (RAN) node (or equipment). At present, some examples of network equipment are: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), base band unit (BBU), or wireless fidelity (Wifi) access point (AP), etc. In addition, in a network structure, the network equipment may include a centralized unit (CU) node and a distributed unit (DU) node. CU implements some functions of gNB, and DU implements some functions of gNB. For example, CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. DU is responsible for processing physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC), media access control (MAC) and physical (PHY) layers.

[0065] 3) An architecture where multiple CCs share a transceiver channel for transceiver transmission. For example, in the case of intra-band CA in the FR2 band, multiple CCs share a transceiver channel (such as an RF transceiver channel) for transceiver transmission. Figure 3 As shown, the analog-to-digital converter (analog -The bandwidth (BW) processed by the digital to digital converter (ADC) includes the total bandwidth of the downlink CC and the gap between the downlink CCs, such as the total bandwidth of CC1 and CC2 and the gap between CC1 and CC2.

[0066] In addition, since the uplink and downlink channels of the transceiver channel share a PLL, the position of the LO is consistent for the uplink CC and the downlink CC. Figure 4 As shown, when multiple CCs (including uplink CCs and downlink CCs) share one transceiver channel, the transceiver channel supports a total of 8 CCs, wherein CC1 is an uplink (UL) CC, and CC1 to CC8 are downlink (DL) CCs.

[0067] 4) Existing terminal equipment capability information reporting mechanism: Existing terminal equipment reports the frequency span level separately for uplink and downlink.

[0068] For the frequency span class (separation class) of non-contiguous carrier aggregation (non-contiguous CA), as shown in Table 5.3A.4-2, the TS 38.101-2 protocol defines the frequency span class to indicate the maximum frequency span between the lowest CC lower edge and the highest CC upper edge supported by the terminal device in the downlink or uplink, respectively.

[0069]

[0070] Table 5.3A.4-2

[0071] For example: Referring to Table 5.3A.4-2, the maximum frequency span between the lowest CC lower edge and the highest CC upper edge that the terminal device can support is divided into three levels I, II, and III, which are 800MHz, 1200MHz, and 1400MHz respectively. For non-contiguous CA, after the terminal device reports the frequency span level for uplink and downlink respectively, the network device configures (allocates) non-contiguous CA within the uplink frequency span level and the downlink frequency span level for the terminal device.

[0072] For contiguous carrier aggregation (contiguous CA), the aggregation bandwidth class defines the bandwidth that can be supported under the corresponding number of CCs under contiguous CA, and is reported per band combination (perband combination) as the capability of the terminal device. For example, the definition in the existing protocol TS 38.101 is as shown in the following table.

[0073]

[0074] Table 5.3A.4-1

[0075] As shown in Table 5.3A.4-1, for contiguous CA, taking bandwidth class B in the table as an example, two consecutive CCs can support up to 800MHz. Currently, in the TS 38.101 protocol, bandwidth class is also reported separately for uplink and downlink.

[0076] However, the bandwidth and center frequency of the uplink CC and downlink CC are configured by the network equipment for the terminal equipment respectively, and there is no correlation between them. Therefore, the bandwidth and center frequency of the uplink CC and downlink CC are likely to be configured differently. Figure 5A As shown, the terminal device reports the uplink frequency span class (UL separation class) and the downlink frequency span class (DL separation class) separately, and the network device configures the uplink CC and downlink CC for the terminal device according to the UL separation class and DL separation class reported by the terminal device, which may be as follows Figure 5A As shown in the figure (the center frequencies of the uplink CC and the downlink CC are aligned, but the bandwidths are different), the overall frequency span including the uplink CC and the downlink CC is from the left edge of the uplink CC1 to the right edge of the downlink CC3, which exceeds the ULseparation class and DL separation class reported by the terminal device, making it impossible for the terminal device to support the uplink CC and downlink CC configured by the network device for the terminal.

[0077] Reference Figure 5B As shown in the figure (the central frequencies of the uplink CC and the downlink CC are not aligned, and the bandwidth is the same), there may also be a situation where the terminal device cannot support the uplink CC and the downlink CC configured by the network device for the terminal.

[0078] Take contiguous CA as an example, refer to Figure 6As shown, the terminal device reports the uplink aggregate bandwidth class (UL bandwidth class) and the downlink aggregate bandwidth class (DL bandwidth class) separately, and the network device configures the uplink CC and downlink CC for the terminal device according to the UL Bandwidth class and DL Bandwidth class reported by the terminal device. It may also happen that the overall frequency span including the uplink CC and downlink CC configured for the terminal device exceeds the UL bandwidth class and DL bandwidth class reported by the terminal device, and the terminal device cannot support the uplink CC and downlink CC configured by the network device for the terminal.

[0079] The present application aims to solve the problem that due to incomplete capability information reported by a terminal device, a network device configures an uplink component carrier and a downlink component carrier for a terminal device according to the capability information reported by the terminal device, but the terminal device cannot support the uplink component carrier and the downlink component carrier, resulting in a mismatch between the capability reported by the terminal device and the configuration sent by the network device.

[0084] Figure 7 A communication process diagram provided in an embodiment of the present application includes:

[0085] S701: The terminal device generates capability information, where the capability information includes an overall frequency span level of the terminal device.

[0086] Among them, the overall frequency span level of the terminal device is used to indicate the overall maximum frequency span supported by the terminal device, and the overall maximum frequency span is the maximum frequency span between the lowest component carrier and the highest component carrier including the uplink component carrier and the downlink component carrier supported by the terminal device.

[0087] In addition, it should be understood that the uplink frequency span level of the terminal device involved in the embodiments of the present application is used to indicate the maximum uplink frequency span supported by the terminal device, and the downlink frequency span level of the terminal device is used to indicate the maximum downlink frequency span supported by the terminal device, and the uplink maximum frequency span supported by the terminal device is the maximum frequency span between the lowest component carrier and the highest component carrier of the uplink component carrier supported by the terminal device; the downlink maximum frequency span supported by the terminal device is the maximum frequency span between the lowest component carrier and the highest component carrier of the downlink component carrier supported by the terminal device. For scenarios where there is no gap between uplink component carriers and downlink component carriers, such as contiguous CA, the uplink frequency span level may also be referred to as the uplink aggregation bandwidth level, and the downlink frequency span level may also be referred to as the downlink aggregation bandwidth level.

[0088] As Fig. 8A Taking the distribution of uplink component carrier (UL CC) and downlink component carrier (DL CC) as an example (there are gaps between uplink carrier components and downlink carrier components), UL CC min Indicates the lowest uplink component carrier, UL CC max Indicates the highest uplink component carrier among the above component carriers, DL CC min Indicates the lowest downlink component carrier, DL CC among the above component carriers max represents the highest downlink component carrier among the above component carriers, the lowest component carrier among the above component carriers (CC min ) and the highest component carrier (CC max ) are DL CC min and DL CC max The maximum uplink frequency span is UL CC min With UL CC max The maximum uplink frequency span between DL CC min With DLCC max The maximum downlink frequency span between the two, the overall maximum frequency span is CC min With CC max That is, in the embodiment of the present application, the overall frequency span level reported by the terminal device can be used to determine the maximum value of the overall frequency span between the UL CC and the DL CC when the network device configures the UL CC and the DL CC for the terminal device.min With CC max The maximum frequency span between them is limited.

[0089] For Figure 8B The distribution of uplink component carriers (UL CC) and downlink component carriers (DL CC) is shown (there is no gap between uplink carrier components and downlink carrier components), and the maximum uplink frequency span is also UL CC min With UL CC max The maximum uplink frequency span and the maximum downlink frequency span between DL CC min With DL CC max The maximum downlink frequency span between the two and the overall maximum frequency span are also CC min (UL CC min ) and CC max (UL CC max or DL ​​CC max The overall frequency span level reported by the terminal device can also be used to determine the maximum value of the overall frequency span between the UL CC and the DL CC when the network device configures the UL CC and the DL CC for the terminal device. min With CC max The maximum frequency span between them is limited.

[0090] In the embodiment of the present application, the frequency span between any two component carriers refers to the frequency span between the lower edge of the lowest component carrier and the upper edge of the highest component carrier among any two component carriers. Fig. 8A CC min With CC max For example, CC min With CC max The frequency span between CC min The lower edge of CC max The frequency span between the upper edges of CC min With CC max The maximum frequency span between CC min The lower edge and CC max The maximum frequency span between the upper edges of

[0091] It should be understood that, in the embodiment of the present application, the "lowest" involved in the lowest component carrier and the highest component carrier refers to the lowest of the lowest frequencies (lower edges) among the component carriers, and the "highest" refers to the highest of the highest frequencies (upper edges) among the component carriers.

[0092] Optionally, the overall frequency span may also be the maximum frequency span between a first component carrier and a second component carrier supported by the terminal device, wherein the first component carrier is the lowest component carrier including an uplink component carrier and a downlink component carrier supported by the terminal device, and the second component carrier is the highest component carrier including an uplink component carrier and a downlink component carrier supported by the terminal device. Fig. 8A The component carrier distribution shown in the figure is min is the first component carrier, DL CC max is the second component carrier.

[0093] In the embodiment of the present application, the overall maximum frequency span indicated by the overall frequency span level of the terminal device limits the overall frequency span including the uplink component carrier and the downlink component carrier supported by the terminal device, so as to avoid the network device configuring the uplink component carrier and the downlink component carrier for the terminal device only according to the uplink maximum frequency span supported by the terminal device and the supported downlink maximum frequency span (only according to the uplink frequency span level and the downlink frequency span level of the terminal device), resulting in the overall frequency span of the uplink component carrier and the downlink component carrier configured for the terminal device exceeding the uplink maximum frequency span and the supported downlink maximum frequency span supported by the terminal device, resulting in the problem that the transceiver channel shared by the terminal device cannot be supported.

[0094] Based on this, in one possible implementation, the overall maximum frequency span supported by the terminal device is equal to the maximum value of the uplink maximum frequency span and the downlink maximum frequency span supported by the terminal device. That is, the overall frequency span level of the terminal device is the same as the maximum frequency span level of the uplink frequency span level and the downlink frequency span level of the terminal device, and is usually the same as the downlink frequency span level. Among them, the maximum frequency span level means that the maximum frequency span range indicated by the frequency span level is the largest. For example, if the uplink maximum frequency span indicated by the uplink frequency span level is 600MHz, and the downlink maximum frequency span indicated by the downlink frequency span level is 800MHz, then the downlink frequency span level is greater than the uplink frequency span level, and the overall frequency span level of the terminal device is the same as the downlink frequency span level.

[0095] In addition, in order to facilitate the network device to learn the maximum uplink frequency span and downlink frequency span supported by the terminal device, in a possible implementation, the capability information generated by the terminal device also includes the uplink frequency span level and downlink frequency span level of the terminal device.

[0096] In another possible implementation, when the overall frequency span level of the terminal device is the same as the maximum frequency span level of the uplink frequency span level and the downlink frequency span level of the terminal device, in order to save signaling overhead, the capability information generated by the terminal device also includes terminal type indication information for indicating whether the uplink frequency span level and the downlink frequency span level of the terminal device are the same, and the uplink frequency span level and the downlink frequency span level of the terminal device are included in the generated capability information only when the uplink frequency span level and the downlink frequency span level of the terminal device are different.

[0097] Among them, the terminal device type indication information may include a first terminal device type identifier (such as UE type1) or a second terminal device type identifier (such as UE type2), the first terminal device type identifier is used to indicate that the uplink frequency span level and the downlink frequency span level of the terminal device are the same; the second terminal device type identifier is used to indicate that the uplink frequency span level and the downlink frequency span level of the terminal device are different.

[0098] Specifically, if the BB, RF and adopted LO of the transceiver channel of the terminal device support the same maximum uplink frequency span and maximum downlink frequency span, it means that the uplink frequency span level and the downlink frequency span level of the terminal device are the same as the overall frequency span level. The network device can accurately know the uplink frequency span level and the downlink frequency span level of the terminal device through the overall frequency span level of the terminal device. In order to save signaling overhead, the capability information generated by the terminal device may only include the overall frequency span level of the terminal device and the first terminal device type identifier used to indicate that the uplink frequency span level and the downlink frequency span level of the terminal device are the same.

[0099] As an example, if the maximum uplink frequency span supported by the terminal device is 600MHz, the maximum downlink frequency span supported by the terminal device is 800MHz, and the overall frequency span level supported by the terminal device is 800MHz, the uplink frequency span level used by the terminal device to indicate the maximum uplink frequency span supported by the terminal device and the downlink frequency span level used to indicate the maximum downlink frequency span supported by the terminal device are different, and the uplink frequency span level and the downlink frequency span level of the terminal device cannot be known according to the overall frequency span of the terminal device. When the terminal device generates capability information, the capability information includes the overall frequency span level of the terminal device, a second terminal device type identifier used to indicate that the uplink frequency span level and the downlink frequency span level of the terminal device are different, and the uplink frequency span level of the terminal device and the downlink frequency span level of the terminal device.

[0100] If the maximum uplink frequency span supported by the terminal device is 800MHz, the maximum downlink frequency span supported by the terminal device is 800MHz, and the overall frequency span level supported by the terminal device is 800MHz, the uplink frequency span level used by the terminal device to indicate the maximum uplink frequency span supported by the terminal device and the downlink frequency span level used to indicate the maximum downlink frequency span supported by the terminal device are the same, the uplink frequency span level and the downlink frequency span level of the terminal device can be known according to the overall frequency span of the terminal device, and when the terminal device generates capability information, the capability information only includes the overall frequency span level of the terminal device and the first terminal device type identifier used to indicate that the uplink frequency span level and the downlink frequency span level of the terminal device are the same.

[0101] S702: The terminal device sends the capability information to the network device, and the network device receives the capability information sent by the terminal device.

[0102] In a possible implementation, the capability information may be sent to the network device via a radio resource control (RRC) message.

[0103] S703: The network device configures an uplink component carrier and a downlink component carrier for the terminal device according to the capability information.

[0104] After receiving the capability information sent by the terminal device, the network device determines the uplink maximum frequency span, downlink maximum frequency span and overall maximum frequency span supported by the terminal device according to the uplink frequency span level, downlink frequency span level and overall frequency span level of the terminal device, and configures an uplink component carrier and a downlink component carrier for the terminal device within the uplink maximum frequency span, downlink maximum frequency span and overall frequency span supported by the terminal device.

[0105] Taking the capability information sent by the terminal device as an example, determining that the maximum uplink frequency span supported by the terminal device is 600MHz, the maximum downlink frequency span is 800MHz, and the overall maximum frequency span is 800MHz, the uplink component carrier and the downlink component carrier configured by the network device for the terminal device can be as follows: Fig. 9A As shown in FIG. 1 , the uplink frequency span of the uplink component carrier is less than or equal to 600 MHz, the downlink frequency span of the downlink component carrier is less than or equal to 800 MHz, and the overall frequency span including the uplink component carrier and the downlink component carrier is less than or equal to 800 MHz. By including the overall frequency span level of the terminal device in the capability information, the following situations are avoided: Fig. 9B and Fig. 9CAs shown, the frequency span of the uplink component carrier is less than or equal to 600 MHz, and the frequency span of the downlink component carrier is less than or equal to 800 MHz, but the overall frequency span including the uplink component carrier and the downlink component carrier is greater than 800 MHz, resulting in the terminal device being unable to support the uplink component carrier and the downlink component carrier configured by the network device for the terminal device, resulting in a mismatch between the capabilities reported by the terminal and the configuration sent by the network.

[0106] In a possible implementation, the uplink component carrier and the downlink component carrier supported by the terminal device may be located on a band combination consisting of one or more bands. That is, the uplink component carrier and the downlink component carrier configured by the network device for the terminal device may be on one band or on multiple bands, and may be applicable to scenarios such as intraband contiguous CA / DC, intraband non-contiguous CA / DC, and inter-band CA / DC.

[0107] It should be understood that the above-mentioned capability information is generated for a single transceiver channel of the terminal device. Optionally, when the carrier spectrum span of the network device is large, such as when the spectrum span in scenarios such as intra band CA / DC and / or inter band CA / DC increases, and the terminal device cannot be supported by one transceiver channel, the terminal device may also be supported by multiple channels. The terminal device generates one or more capability information corresponding to the one or more transceiver channels for its own one or more transceiver channels, and sends the capability information to the network device. The network device configures uplink component carriers and downlink component carriers for one or more transceiver channels of the terminal device according to the one or more capability information corresponding to the one or more transceiver channels reported by the terminal device, so as to improve the communication capability between the network device and the terminal device.

[0108] For example: For sending / reporting of capability information of multiple transceiver channels, the terminal device may implement it in an array manner. Taking transceiver channel 1 and transceiver channel 2 as an example, the terminal device may send an RRC message containing separation class1+separation class2 to the network device to report the capability information of transceiver channel 1 and transceiver channel 2 of the terminal device, where separation class1 indicates the capability information of transceiver channel 1 of the terminal device, and separation class2 indicates the capability information of transceiver channel 2 of the terminal device. The network device configures an uplink component carrier and a downlink component carrier for transceiver channel 1 of the terminal device according to separation class1, and configures an uplink component carrier and a downlink component carrier for transceiver channel 2 of the terminal device according to separation class1.

[0109] In addition, for scenarios such as inter-band CA / CD, the terminal device can use a frequency band combination to report the uplink frequency span and downlink frequency span of the terminal device on the frequency band combination, thereby enriching the capability information reporting method and saving signaling overhead. The following is a detailed description in conjunction with the embodiments.

[0110] [Example 2]

[0111] Fig.10 A communication process diagram provided in an embodiment of the present application includes:

[0112] S1001: A terminal device generates capability information, where the capability information includes an uplink frequency span level and a downlink frequency span level of the terminal device on a frequency band combination consisting of multiple bands.

[0113] In an embodiment of the present application, for scenarios where there are multiple bands such as inter-band CA / DC, if the frequencies of multiple bands are adjacent, the terminal device can adopt a band combination granularity (per bandcombination) approach when reporting capability information to the network device, that is, the terminal device reports an uplink frequency span level and a downlink frequency span level as a whole for the band combination composed of multiple bands.

[0114] For example, taking the frequency band combination of band1, band2, and band3 as an example, the terminal device generates capability information including uplink frequency span level information on (band1+band2+band3) and downlink frequency span level information on (band1+band2+band3).

[0115] S1002: The terminal device sends the capability information to the network device, and the network device receives the capability information sent by the terminal device.

[0116] In a possible implementation, the capability information may be sent to the network device via an RRC message.

[0117] S1003: The network device configures an uplink component carrier and a downlink component carrier for the terminal device according to the capability information.

[0118] After receiving the capability information sent by the terminal device, the network device configures uplink component carriers and downlink component carriers for multiple bands in the frequency band combination according to the uplink frequency span and downlink frequency span of the terminal device on the frequency band combination.

[0119] For example, the capability information sent by the terminal device includes an uplink frequency span level of "II" on the frequency band combination (band1+band2+band3), and a downlink frequency span level of "II" on the frequency band combination (band1+band2+band3). The network device configures uplink component carriers in band1, band2 and band3 for the terminal device within the uplink frequency span level "II", and configures downlink component carriers in band1, band2 and band3 for the terminal device within the downlink frequency span level "II".

[0120] It should be understood that the above-mentioned capability information is generated for a single transceiver channel of the terminal device. Optionally, when the carrier spectrum span of the network device is large, such as the spectrum span of inter-band CA / DC and other scenarios increases, and the terminal device cannot be supported by one transceiver channel, the terminal device can also be supported by multiple channels. The terminal device generates one or more capability information corresponding to the one or more transceiver channels for its own one or more transceiver channels, and sends it to the network device. The network device configures uplink component carriers and downlink component carriers for one or more transceiver channels of the terminal device according to the one or more capability information corresponding to the one or more transceiver channels reported by the terminal device, so as to improve the communication capability between the network device and the terminal device.
