The centralized unit is provided with a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer, a radio link layer control protocol (Radio Link Control, RLC) layer, and a media access control (Media Access Control, MAC) layer protocol stack; the distributed unit is provided with a physical (Physical, PHY) layer protocol stack. The specific implementation method of the network device 12 is not limited in the embodiment of the present disclosure.

In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface is a new air interface; or, the wireless air interface can also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

As shown in FIG. 2 , an embodiment of the present disclosure provides an information processing method, which is executed by a UE and includes:

S1110: Send indication information to a network device; wherein the indication information is used to indicate whether the UE supports BFR enhancement of the secondary cell.

The UE may be any type of UE. For example, the UE may be a mobile device such as a mobile phone, a tablet computer, a wearable device, or a vehicle-mounted device, or a terminal device such as a smart home device and/or a smart office device. For example, the UE may be a mobile device. In short, the UE may be any communication device that supports CA.

Exemplarily, the UE may support a first frequency range (Frequency Range 1, FR1) and/or support a terminal of a second frequency range (FR2). In an example, an average frequency of the second frequency range is higher than an average frequency of the first frequency range; and/or, a lowest frequency of the second frequency range is higher than a highest frequency of the first frequency range. In particular, the UE may support FR1 and FR2 simultaneously.

The UE supports BFR enhancement of the secondary cell in FR1 and/or FR2.

The network device may be an access network device and/or a core network device. The access network device includes but is not limited to various types of base stations. The base station may include but is not limited to: an evolved base station (eNB) and/or a next generation base station (gNB).

The indication information may be used to indicate whether the UE supports BFR enhancement of the secondary cell in a high-speed mobility scenario.

The high-speed movement scenario may include at least one of the following:

The UE's moving speed per unit time is higher than the preset speed;

Scenes on high-speed trains;

Scenarios on subways or urban rails;

A scene with communication equipment running on a highway.

In one example, in a non-high-speed mobility scenario, the indication information may not be reported to reduce signaling overhead.

Of course, the above is merely an example of a high-speed moving scenario, and the specific implementation is not limited to the above example.

The BFR enhancement may include: enhancement of beam failure detection (Beam Failure Detection, BFD) and/or enhancement of candidate beam detection (Candidate Beam Detection, CBD).

Beam failure detection: Detect the current service beam of the UE. The detected service beam may include any one of the beams of the primary and secondary cells of the UE and the beams of the secondary cell.

In some examples, the measurement results within the BFD evaluation period (TEvaluate_BFD) are compared with the threshold. If all measurement results are below the threshold, a beam failure indication is triggered. One beam failure indication represents a beam failure. In one example, the aforementioned threshold may be a block error rate threshold, etc. Before the configured beam failure detection timer expires, if the number of beam failure indications of layer 1 reaches the configured threshold, the UE declares a beam failure (Beam Failure) and starts CBD.

Candidate beam detection includes: the network configures the candidate beam set for the UE, and the UE detects the candidate beams in the candidate beam set based on the comparison of the measurement results of the candidate beams within the evaluation period of the CBD with the configured threshold, and the candidate beams with measurement results higher than the threshold are used as available new beams. The UE notifies the network of the available new beams found so that the network knows that the new beam can be used for downlink transmission. The RSRP is the reference signal received power, and the corresponding English original is: Reference Signal Received Power.

In the disclosed embodiment, the BFR enhancement may include: shortening the evaluation period of beam failure recovery and/or candidate beam detection, etc. It can be understood that shortening the evaluation period and increasing the evaluation frequency can achieve the enhancement of beam failure recovery and/or candidate beam detection. Through BFR enhancement, the signal quality of the secondary cell communication beam can be more accurately monitored, and other available beams can be quickly determined to restore the connection when a beam failure occurs, thereby ensuring the communication quality between the UE and the base station. The communication beam can be a target beam selected from the available beams by the base station and the UE through negotiation for communication between the base station and the UE.

The specific content of the indication information may be various. Exemplarily, the indication information includes one or more bits, which explicitly indicate whether the UE supports secondary cell BFR enhancement.

In the embodiment of the present disclosure, the indication information reported by the UE to the base station and other network devices can be used to indicate whether the UE supports BFR enhancement of the secondary cell (Scell). In this way, a basis can be provided for the network device to configure the Scell for the UE subsequently. For example, a reference basis is provided for the network device to configure the BFR configuration of the secondary cell for the UE, thereby making the best use of the terminal capabilities of the UE to improve the communication effect.

The network devices such as base stations herein may be: base stations of primary cells of UE and/or base stations of secondary cells of UE, etc.

In some embodiments, the indication information is used to indicate whether the UE supports BFR enhancement of the secondary cell in the HST scenario.

If the UE is in the HST scenario, it means that the UE is in a high-speed motion state and may switch between cells on both sides of the high-speed train line at high speed.

In the disclosed embodiment, the indication information can be particularly used for BFR enhancement of the secondary cell in the HST scenario. In the HST scenario, due to the high-speed movement of the UE, it will frequently switch between multiple cells. Therefore, the target cell of the UE cell switching can be accurately measured through BFR enhancement, which facilitates the UE to quickly access the target cell that can ensure the communication quality of the UE. In some embodiments, if the UE supports BFR enhancement of the secondary cell in high-speed motion scenarios such as HST scenarios, it can be assumed that the UE supports BFR enhancement of the secondary cell in non-high-speed mobile scenarios (or high-speed motion scenarios).

In some embodiments, the indication information is carried in various high-level messages. Exemplarily, the high-level signaling includes but is not limited to a Radio Resource Control (RRC) message or a Media Access Control (MAC) message.

In other embodiments, the indication information may also be carried in a physical layer message and sent to a network device such as a base station. The physical layer message may at least include: uplink control information (UCI) and the like.

In some embodiments, the indication information is used to indicate whether the UE supports a first type of secondary cell beam failure recovery BFR enhancement; and/or, is used to indicate whether the UE supports a second type of secondary cell beam failure recovery BFR enhancement.

In one example, the first type of secondary cell beam failure recovery BFR enhancement may be a secondary cell beam failure recovery BFR enhancement for a specific UE, also referred to as a UE-level secondary cell beam failure recovery BFR enhancement. In a specific implementation, the UE-level secondary cell beam failure recovery BFR enhancement includes performing secondary cell beam failure recovery BFR enhancement on all available frequency bands for the specific UE. For example, if the UE supports all frequency bands in FR2, then the UE-level secondary cell beam failure recovery BFR enhancement includes supporting the UE's secondary cell beam failure recovery BFR enhancement on all frequency bands in FR2.

In some embodiments, the indication information indicates that the UE supports UE-level secondary cell BFR enhancement, indicating that the UE supports BFR enhancement in all frequency ranges where secondary cells can be set. For example, the indication information may be used to indicate that the UE supports UE-level secondary cell BFR enhancement, indicating that the UE supports BFR enhancement of secondary cells in RF2.

For another example, if the indication information indicates that the UE supports UE-level BFR enhancement of the secondary cell in the HST scenario, it means that the UE can set the BFR enhancement within the frequency range of the secondary cell in the HST scenario.

The second type of secondary cell beam failure recovery BFR enhancement may be a secondary cell beam failure recovery BFR enhancement for a specific frequency band, also referred to as a secondary cell beam failure recovery BFR enhancement at the frequency band level. In a specific implementation, the secondary cell beam failure recovery BFR enhancement at the frequency band level includes performing secondary cell beam failure recovery BFR enhancement on the specific frequency band. For example, if the specific frequency band is frequency band 1 in FR2. Then, the secondary cell beam failure recovery BFR enhancement at the frequency band level includes supporting the UE to perform secondary cell beam failure recovery BFR enhancement on frequency band 1 of FR2, and does not support performing secondary cell beam failure recovery BFR enhancement on other non-frequency bands 1 in FR2.

A frequency range may include multiple frequency bands. For example, FR2 may include frequency bands n253 to n263. For example, the UE supports BFR enhancement of the secondary cell on frequency band 1 among n253 to n263 corresponding to FR2, while does not support BFR enhancement of the secondary cell on frequency band 2 among n253 to n263 corresponding to FR2. In an example, the specific frequency band on which BFR enhancement is supported or not supported can be configured according to the capabilities of the UE and the capabilities within the UE. It can be seen that if the UE supports BFR enhancement of the secondary cell at the frequency band level, the UE does not uniformly support BFR enhancement of the secondary cell or uniformly does not support BFR enhancement of the secondary cell over the entire frequency range (e.g., FR2), but needs to be detailed to each frequency band within the frequency range. Exemplarily, the indication information may indicate that the UE supports BFR enhancement of the secondary cell at the UE level or the frequency band level, so that the indication of whether UEs of different levels support BFR enhancement of the secondary cell can be implemented. Assuming that the indication information indicates whether the UE supports BFR enhancement at the secondary cell frequency band level in the HST scenario, the base station and other network devices receive the indication information and can determine whether the UE supports BFR enhancement at the frequency band level in the HST scenario. When performing subsequent BFR configuration, targeted configuration can be performed based on the UE's indication information.

In some embodiments, the indication information is used to indicate whether the UE supports frequency band level secondary cell beam failure recovery BFR enhancement.

Optionally, when the indication information is used to indicate that the UE supports frequency band level BFR enhancement, the indication information also includes frequency band information that the UE supports beam failure recovery BFR enhancement of the secondary cell.

For example, the indication information indicates whether the UE supports secondary cell BFR enhancement, and the specific content of the indication information may include:

Frequency band information of the secondary cell BFR enhancement supported by the UE. In one example, the frequency band information may include a frequency band number and the like.

In one embodiment, if the indication information includes frequency band information of at least one frequency band, it may represent that the UE supports frequency band level secondary cell BFR enhancement, and the supported frequency band is the frequency band represented by the frequency band information. If cell A is set on the frequency band indicated by the frequency band information, if cell A is the secondary cell of the UE, the UE may perform BFR enhancement in cell A.

In this case, it is equivalent to whether the frequency band information is carried in an indication information, which is used to implicitly indicate whether the UE supports the BFR enhancement of the secondary cell at the frequency band level. If the indication information does not carry the frequency band information or the indication information is empty, it means that the UE does not support the BFR enhancement of the secondary cell at the frequency band level or does not support the BFR enhancement of the secondary cell.

In some embodiments, the indication information is included in a first IE or a second IE; wherein the first IE is a UE indication information unit IE; and the second IE is different from the first IE.

The indication information may be carried in an IE proposed in the related art, or may be carried in a dedicated IE. The IE may be an IE proposed for the indication information.

Exemplarily, the UE indication information element corresponding to the first IE may be the maximum number of BFR enhancement (maxNumberSCellBFRHSTEnhancement-r18) IE in the secondary cell HST scenario of version 18. The second IE may be any IE different from the aforementioned first IE.

If the aforementioned indication information indicating whether the UE supports the secondary cell BFR enhancement is carried in the first IE, it means that the indication information indicating whether the UE supports the secondary cell BFR enhancement and other indication information of the UE are carried in the same IE. If the aforementioned indication information indicating whether the UE supports the secondary cell BFR enhancement is carried in the second IE, it means that other capability information of the UE and the indication information are carried in different IEs.

In the aforementioned embodiment, the first IE and the second IE may be sent to a network device such as a base station through the same message or different messages.

Exemplarily, both the first IE and the second IE may be sent to a network device such as a base station via UE indication information (UECapabilityInformation), so that the network device can obtain as much UE indication information as possible via one message.

As shown in FIG3 , an embodiment of the present disclosure provides an information processing method, which is executed by a UE and includes:

S1210: Send an RRC message to a network device, where the RRC message includes the indication information; wherein the indication information is used to indicate whether the UE supports BFR enhancement of the secondary cell.

Sending a radio resource control (RRC) message including the indication information to the network device.

In this embodiment, the indication information is sent to a network device such as a base station via an RRC message, so that the information content of the indication information is relatively flexible.

In some embodiments, the UE supports BFR enhancement of the secondary cell, and the indication information includes a designated field.

In some other embodiments, the UE does not support BFR enhancement of the secondary cell, and the indication information does not include a designated field.

In this way, the network device that receives the indication information can determine whether the UE supports the BFR enhancement of the secondary cell according to whether the indication information includes the designated field.

The designated field may include one or more bits.

In some embodiments, the indication information includes: secondary cell number information, indicating the number of secondary cells that the UE supports the BFR enhancement.

If the UE supports BFR enhancement for secondary cells, since a UE supports a large number of secondary cells, the secondary cell number information can further indicate how many secondary cells the UE can perform BFR enhancement on simultaneously, which depends on the software and hardware capabilities of the UE.

Exemplarily, the secondary cell number information may be an enumeration method to indicate the number of secondary cells that the UE supports BFR enhancement.

As another example, if different bits in a field of multiple bits represent different numbers of secondary cells, it can be indicated by setting the bit corresponding to the number of secondary cells for which the UE supports BFR enhancement to 0 or 1.

In one embodiment, the BFR enhancement of the secondary cell may include:

When BFR is enhanced, the evaluation period of BFD performed by the UE is shorter than the evaluation period of BFD when BFR enhancement is not performed; and/or, the evaluation period of CBD performed by the UE when BFR is enhanced is shorter than the evaluation period of CBD when BFR enhancement is not performed.

In some embodiments, the beam failure recovery BFR enhancement of the secondary cell in the high HST scenario includes: the evaluation period of the secondary cell beam failure detection BFD in the HST scenario is shorter than the evaluation period of the secondary cell BFD in the non-HST scenario; and/or the evaluation period of the secondary cell candidate beam detection CBD in the HST scenario is shorter than the evaluation period of the secondary cell CBD in the non-HST scenario.

In some embodiments, the UE is a UE with a power level of a preset level.

In the disclosed embodiment, the preset level UE may be a UE of power class (PC) 1-6. Exemplarily, the preset level UE may be a UE of power class 6, i.e., a customer premise equipment (CPE). Also exemplarily, the preset level UE may also be a UE of power class 3, i.e., a handheld UE.

Since the UE of the preset level has a sufficiently large transmit power, carrier aggregation can be supported, thereby supporting camping on a primary cell and one or more secondary cells at the same time.

As shown in FIG. 4 , an embodiment of the present disclosure provides an information processing method, which is executed by a UE and includes:

S1310: Sending indication information of the UE to a network device; wherein the indication information is used to indicate whether the UE supports BFR enhancement of a secondary cell;

S1320: Receive secondary cell configuration information provided by the network device according to the indication information.

In the embodiment of the present disclosure, the UE also receives secondary cell configuration information configured for the UE according to the aforementioned indication information returned by the network device. The secondary cell configuration information may include at least one of the following:

The measurement configuration of the secondary cell may be a BFR configuration.

Since the secondary cell configuration information is provided according to the indication information provided by the UE, the secondary cell configuration information has a higher degree of adaptability to the configuration of the secondary cell and the capability of the UE, which can fully utilize the capability of the UE and reduce invalid configuration when the UE does not support the corresponding capability.

As shown in FIG5 , an embodiment of the present disclosure provides an information processing method, which is executed by a network device and includes:

S2110: Receive indication information sent by the UE; wherein the indication information is used to indicate whether the UE supports BFR enhancement of the secondary cell.

The network device may include but is not limited to a base station, etc. Exemplarily, the network device may be a base station of a primary cell of the UE and/or a base station of a secondary cell of the UE.

The indication information may indicate whether the UE supports BFR enhancement of the secondary cell. For example, if the UE software and hardware capabilities do not support BFR enhancement of the secondary cell or the UE's function of supporting BFR enhancement of the secondary cell is disabled, the indication information will indicate that the UE does not support BFR enhancement of the secondary cell. For another example, if the UE supports BFR enhancement of the secondary cell, the indication information will indicate that the UE supports BFR enhancement.

Exemplarily, the indication information may indicate whether the UE supports BFR enhancement of the secondary cell in a high-speed motion scenario. For example, in some cases, it may be assumed that the UE supports BFR enhancement of the secondary cell in a non-high-speed motion scenario. For the description of the high-speed motion scenario, please refer to the above embodiment, which will not be repeated here.

In some embodiments, the indication information is used to indicate whether the UE supports BFR enhancement of the secondary cell in a high-speed train HST scenario.

In some embodiments, the indication information is used to indicate whether the UE supports beam failure recovery BFR enhancement of the secondary cell at the UE level; or, the indication information is used to indicate whether the UE supports beam failure recovery BFR enhancement of the secondary cell at the frequency band level.

UE support for BFR enhancement of secondary cells can be divided into at least two levels, one is UE level, if the UE supports UE-level BFR enhancement, then the UE can support BFR enhancement of secondary cells set within the frequency range where secondary cells can be set. The other is frequency band level, a frequency range may include multiple frequency bands, at this time, the UE may support BFR enhancement of secondary cells on some frequency bands, but not on other frequency bands.

In summary, in the embodiments of the present disclosure, the indication information may provide indications of BFR enhancement of the secondary cell at two different levels.

In some embodiments, the indication information is used to indicate whether the UE supports the beam failure recovery BFR enhancement of the secondary cell at the frequency band level, and the indication information also includes frequency band information that the UE supports the beam failure recovery BFR enhancement of the secondary cell.

If the UE supports the secondary cell BFR enhancement of the frequency level, the indication information may be carried by carrying the frequency information that the UE supports the secondary cell BFR enhancement.
