[0045] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0046] like Figure 1 As shown, the method for transmitting frequency band information provided in this disclosure can be applied to a wireless communication system 100, which may include, but is not limited to, a network device 101 and a user equipment 102. The user equipment 102 is configured to support carrier aggregation, and the user equipment 102 can be connected to multiple carrier units of the network device 101, including a primary carrier unit and one or more secondary carrier units.

[0047] It should be understood that the wireless communication system 100 described above is applicable to both low-frequency and high-frequency scenarios. Application scenarios for the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for microwave access (WiMAX) communication systems, cloud radio access network (CRAN) systems, future 5th-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile network (PLMN) systems.

[0048] The user equipment 102 shown above can be user equipment (UE), terminal, access terminal, terminal unit, terminal station, mobile station (MS), remote station, remote terminal, mobile terminal, wireless communication equipment, terminal agent, or user equipment, etc. This user equipment 102 may have wireless transceiver capabilities, enabling it to communicate (e.g., wirelessly) with one or more network devices 101 of one or more communication systems, and to receive network services provided by the network devices 101, including but not limited to the base station shown in the figure.

[0049] User equipment 102 may be a cellular phone, cordless phone, session initiation protocol (SIP) phone, wireless local loop (WLL) station, personal digital assistant (PDA) device, handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, user equipment in a future 5G network or user equipment in a future evolved PLMN network, etc.

[0050] Network device 101 can be an access network device (or access point). Access network device refers to equipment that provides network access functionality, such as a radio access network (RAN) base station. Specifically, network device may include base station (BS) equipment, or base station equipment and radio resource management equipment used to control the base station equipment. This network device may also include relay stations (relay equipment), access points, and base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations. Network device can be a wearable device or an in-vehicle device. Network device can also be a communication chip with a communication module.

[0051] For example, network equipment 101 includes, but is not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB) in LTE systems, radio network controllers (RNC), node B (NB) in WCDMA systems, radio controllers and base station controllers (BSC) in CRAN systems, base transceiver stations (BTS) in GSM or CDMA systems, home base stations (e.g., home evolved nodeB, or home node B, HNB), baseband units (BBU), transmitting and receiving points (TRP), transmitting points (TP), or mobile switching centers, etc.

[0052] The network may include a first type of terminal and a second type of terminal. The first type of terminal may be a capability-reduced terminal (RedCap UE); the second type of terminal may be a normal terminal (referred to as Legacy UE or non-RedCap UE) or an enhanced mobile broadband (eMBB) terminal. The terminal capability of the first type of terminal is less than that of the second type of terminal; for example, the bandwidth supported by the first type of terminal is less than that supported by the second type of terminal.

[0053] When a user equipment can use a multi-antenna transceiver, each antenna element can correspond to multiple (e.g., multiple) transceiver chains, each of which includes a transmitter path and a receiver path.

[0054] User equipment (UE) uses a transceiver chain to process signals within a certain frequency range. If the frequency range of the signals that the UE needs to process is large, multiple transceiver chains need to be used simultaneously. The frequency range corresponding to each transceiver chain of the UE is related to the corresponding hardware configuration. The more transceiver chains the UE uses, the greater the RF power consumption.

[0055] This disclosure provides a method for transmitting frequency band information. Figure 2 This is a flowchart illustrating a method for transmitting frequency band information according to an exemplary embodiment, such as... Figure 2 As shown, the method includes:

[0056] Step S201: The user equipment sends the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment to the network equipment.

[0057] In some possible implementations, there are multiple ways in which the user equipment sends the identifier of the radio frequency logic unit to the network equipment.

[0058] For example:

[0059] The user equipment sends radio frequency capabilities to the network equipment, and the radio frequency capabilities include the identifiers of the radio frequency logic units corresponding to the frequency bands supported by the user equipment.

[0060] For example:

[0061] The user equipment sends carrier aggregation capability to the network equipment, and the carrier aggregation capability includes the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment.

[0062] In some possible implementations, the identifier of an RF logic unit corresponds to a transceiver path. For example, the identifier of an RF logic unit corresponds to a transceiver chain.

[0063] In some possible implementations, each frequency band supported by the user equipment corresponds to the identifier of at least one radio frequency logic unit.

[0064] In some possible implementations, each frequency band supported by the user equipment corresponds to an identifier for a radio frequency logic unit. The identifiers for the radio frequency logic units corresponding to different frequency bands are different.

[0065] In some possible implementations, when the bandwidth of a frequency band supported by the user equipment is greater than a set bandwidth, the frequency band corresponds to the identifier of multiple radio frequency logic units. For example, when the user equipment supports band77 (with a bandwidth of 900MHz), band77 corresponds to the identifier of multiple radio frequency logic units.

[0066] In some possible implementations, at least two frequency bands supported by the user equipment correspond to the identifier of the same radio frequency logic unit.

[0067] In some possible implementations, the radio frequency logic unit is a transceiver chain, a transceiver unit, or an antenna unit.

[0068] In step S202, the network device determines the carrier aggregation configuration information of the user equipment based on the identifier of the radio frequency logic unit.

[0069] In some possible implementations, at least two frequency bands in the carrier aggregation configuration information determined by the network device correspond to the identifier of the same radio frequency logic unit.

[0070] In some possible implementations, when setting the carrier aggregation configuration information for carrier aggregation within a frequency band, the network device enables the user equipment to use as little radio frequency logic (e.g., transceiver chains) as possible to complete data transmission and reception to each secondary cell (scell).

[0071] Step S203: The network device sends the carrier aggregation configuration information to the user equipment.

[0072] In one example:

[0073] User equipment supports carrier aggregation of five carriers within the FR1 band (interband), specifically represented as CA_n1-n3-n5-n7-n78, meaning the five supported frequency bands are n1, n3, n5, n7, and n78. The user equipment supports five transceiver chains, each corresponding to one of the aforementioned five frequency bands.

[0074] The radio frequency capabilities that user equipment transmits to network equipment include:

[0075] The identifier of the first transceiver chain corresponding to frequency band n1.

[0076] The identifier of the second transceiver chain corresponding to frequency band n3.

[0077] The identifier of the third transceiver chain corresponding to frequency band n5.

[0078] The identifier of the fourth transceiver chain corresponding to frequency band n7.

[0079] The identifier of the fifth transceiver chain corresponding to frequency band n78.

[0080] The network device determines the carrier aggregation configuration information of the user equipment based on the radio frequency capability.

[0081] In another example:

[0082] User equipment supports carrier aggregation of four carriers within the FR1 band (interband). The four supported bands are band nx1, band nx2, band nx3, and band nx4. Bands nx1 and nx2 both correspond to the first transceiver chain, which is identified as U1. Bands nx3 and nx4 both correspond to the second transceiver chain, which is identified as U2.

[0083] The radio frequency capabilities that user equipment transmits to network equipment include:

[0084] Frequency band nx1 corresponds to identifier U1 of the first transceiver chain.

[0085] Frequency band nx2 corresponds to identifier U1 of the first transceiver chain.

[0086] Frequency band nx3 corresponds to identifier U2 of the first transceiver chain.

[0087] Frequency band nx4 corresponds to identifier U2 of the first transceiver chain.

[0088] After receiving this radio frequency capability, when a user equipment needs to use carrier aggregation within two frequency bands, it should, where the protocol and actual scheduling allow, try to select the frequency bands corresponding to the same radio frequency logic unit. For example, it can determine the carrier aggregation configuration information of the user equipment, which indicates frequency bands nx1 and nx2, or frequency bands nx3 and nx4.

[0089] In this embodiment of the disclosure, the user equipment reports the identifier of the radio frequency logic unit corresponding to the frequency band it supports, so that the network equipment can accurately know the radio frequency capabilities of the user equipment, thereby providing the user equipment with more reasonable carrier aggregation configuration information, improving carrier aggregation transmission performance, improving resource utilization, and saving power consumption of the user equipment.

[0090] This disclosure provides a method for transmitting frequency band information, executed by a user equipment. Figure 3 This is a flowchart illustrating a method for transmitting frequency band information according to an exemplary embodiment, such as... Figure 3As shown, the method includes:

[0091] Step S301: Send the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment to the network device.

[0092] In some possible implementations, there are multiple ways in which the user equipment sends the identifier of the radio frequency logic unit to the network equipment.

[0093] For example:

[0094] The user equipment sends radio frequency capabilities to the network equipment, and the radio frequency capabilities include the identifiers of the radio frequency logic units corresponding to the frequency bands supported by the user equipment.

[0095] For example:

[0096] The user equipment sends carrier aggregation capability to the network equipment, and the carrier aggregation capability includes the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment.

[0097] In some possible implementations, the identifier of an RF logic unit corresponds to a transceiver path. For example, the identifier of an RF logic unit corresponds to a transceiver chain.

[0098] In some possible implementations, each frequency band supported by the user equipment corresponds to an identifier of at least one radio frequency logic unit.

[0099] In some possible implementations, each frequency band supported by the user equipment corresponds to an identifier for a radio frequency logic unit. The identifiers for the radio frequency logic units corresponding to different frequency bands are different.

[0100] In some possible implementations, when the bandwidth of a frequency band supported by the user equipment is greater than a set bandwidth, the frequency band corresponds to the identifier of multiple radio frequency logic units. For example, when the user equipment supports band77 (with a bandwidth of 900MHz), band77 corresponds to the identifier of multiple radio frequency logic units.

[0101] In some possible implementations, at least two frequency bands supported by the user equipment correspond to the identifier of the same radio frequency logic unit.

[0102] In some possible implementations, the radio frequency logic unit is a transceiver chain, a transceiver unit, or an antenna unit.

[0103] This disclosure provides a method for transmitting frequency band information, executed by a user equipment. Figure 3 This is a flowchart illustrating a method for transmitting frequency band information according to an exemplary embodiment, such as... Figure 4 As shown, the method includes:

[0105] The content of step S401 is the same as that of step S301.

[0106] Step S402: Receive carrier aggregation configuration information sent by the network device.

[0107] In some possible implementations, the carrier aggregation configuration information is determined by the network device based on the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment.

[0108] This disclosure provides a method for receiving frequency band information, executed by a network device. Figure 5 This is a flowchart illustrating a method for receiving frequency band information according to an exemplary embodiment, such as... Figure 5 As shown, the method includes:

[0109] Step S501: Receive the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment, sent by the user equipment.

[0110] In some possible implementations, network devices may receive the identifier of radio frequency logic units in various ways.

[0111] For example:

[0112] The radio frequency capability is received from the user equipment, and the radio frequency capability includes the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment.

[0113] For example:

[0114] The carrier aggregation capability is received from the user equipment, and the carrier aggregation capability includes the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment.

[0115] In some possible implementations, the identifier of an RF logic unit corresponds to a transceiver path. For example, the identifier of an RF logic unit corresponds to a transceiver chain.

[0117] In some possible implementations, each frequency band supported by the user equipment corresponds to an identifier for a radio frequency logic unit. The identifiers for the radio frequency logic units corresponding to different frequency bands are different.

[0118] In some possible implementations, when the bandwidth of a frequency band supported by the user equipment is greater than a set bandwidth, the frequency band corresponds to the identifier of multiple radio frequency logic units. For example, when the user equipment supports band77 (with a bandwidth of 900MHz), band77 corresponds to the identifier of multiple radio frequency logic units.

[0119] In some possible implementations, at least two frequency bands supported by the user equipment correspond to the identifier of the same radio frequency logic unit.

[0120] In some possible implementations, the radio frequency logic unit is a transceiver chain, a transceiver unit, or an antenna unit.

[0123] The content of step S601 is the same as that of step S501.

[0124] Step S602: Determine the carrier aggregation configuration information of the user equipment based on the identifier of the radio frequency logic unit corresponding to the frequency band supported by the user equipment.

[0125] In some possible implementations, at least two frequency bands in the carrier aggregation configuration information determined by the network device correspond to the identifier of the same radio frequency logic unit.

[0126] In some possible implementations, when setting the carrier aggregation configuration information for carrier aggregation within a frequency band, the network device enables the user equipment to use as little radio frequency logic (e.g., transceiver chains) as possible to complete data transmission and reception to each secondary cell (scell).
