[0002] The present disclosure relates to the technical field of communication, and particularly relates to a beam failure request resource allocation method, device and storage medium. BACKGROUND

[0003] In a new radio (NR) communication system, in order to ensure coverage and resist path loss, data transmission and reception based on beams are usually required. In NR, since control channels also need to use beam-based transmission and reception, when the terminal moves or the antenna direction rotates, the beam currently configured for the terminal to transmit and receive may have problems, i.e., beam failure problems.

[0004] In related technologies, when the terminal detects that a secondary cell (SCell) has a beam failure, the network device needs to configure a physical uplink control channel-beam failure request (PUCCH-BFR) resource for the terminal to send a BFR to the network device to indicate that a beam failure has occurred. Currently, for the terminal, the network device (e.g., a base station) may configure multiple PUCCH-BFR resources on different serving cells thereof, and how to select a PUCCH-BFR resource for sending a BFR from the multiple PUCCH-BFR resources is a problem that needs to be solved. SUMMARY

[0018] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements, unless the context dictates otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0019] The beam failure request resource allocation method provided by the embodiments of the present disclosure can be applied to Figure 1 a wireless communication system as shown in FIG. 1. Referring to Figure 1 the wireless communication system includes a network device and a terminal. The terminal is connected to the network device through wireless resources and performs data transmission.

[0020] It can be understood that Figure 1 the wireless communication system shown in FIG. 1 is only illustrative, and the wireless communication system can further include other network devices, such as a core network device, a wireless relay device, and a wireless backhaul device, etc., which are not shown in Figure 1 The embodiments of the present disclosure do not limit the number of network devices and the number of terminals in the wireless communication system.

[0021] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance (CSMA / CA). According to different network capacities, rates, latencies, and other factors, the network can be divided into 2G (English: generation) networks, 3G networks, 4G networks, or future evolution networks such as 5G networks. The 5G network can also be referred to as a new radio network (New Radio, NR). For convenience of description, the wireless communication network is sometimes referred to as a network in the present disclosure.

[0022] Further, the network device involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission and reception point (TRP), etc., and can also be a gNB in an NR system, or can also be a component or a part of a device constituting a base station, etc. It should be understood that the specific technology and specific device form adopted by the network device in the embodiments of the present disclosure is not limited. In the present disclosure, the network device can provide communication coverage for a specific geographic area, and can communicate with terminals located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device.

[0023] Further, the terminal involved in the present disclosure can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity for a user, for example, a terminal can be a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form adopted by the terminal in the embodiments of the present disclosure is not limited.

[0024] In NR, especially when the communication frequency band is in frequency range 2, due to the rapid attenuation of high-frequency channels, in order to ensure coverage, beam-based transmission and reception need to be used between the terminal and the network device.

[0025] In NR, since control channels also need to use beam-based transmission and reception, when the terminal moves or the antenna direction rotates, the beam currently configured to the terminal for transmission and reception may have problems, i.e., beam failure occurs. For example, the transmit beam or receive beam currently configured by the network device to the terminal for transmitting and receiving a physical downlink control channel (PDCCH) may have problems, i.e., beam failure occurs. The current standard defines that for SCell, when the terminal detects that beam failure occurs on the SCell, the beam failure reporting process is divided into two steps: first, the terminal requests physical uplink shared channel (PUSCH) resources based on physical uplink control channel-scheduling request (PUCCH-SR) similar signaling, i.e., PUCCH-BFR, to the network device. Second, the terminal sends the index of the SCell that has beam failure in the form of a medium access control (MAC) control element (CE) through the PUSCH resource allocated by the network device. When the terminal detects a new beam, the terminal sends the index of the new beam on the SCell detected by the terminal in the form of a MAC CE at the same time as sending the index of the SCell that has beam failure.

[0026] In related technologies, when the terminal has beam failure on a secondary cell (SCell), the terminal needs to configure a physical uplink control channel-beam failure request (PUCCH-BFR) resource for sending a BFR to the network device to indicate that beam failure has occurred. Currently, in addition to the primary cell (PCell) or primary secondary cell (PScell), PUCCH resources can be configured for PUCCH-BFR. In addition, a SCell in a service cell that belongs to a different PUCCH group from the PCell / PScell can be selected to configure PUCCH resources for PUCCH-BFR for the terminal. Therefore, for the terminal, multiple PUCCH-BFR resources can be configured, and how to select a PUCCH-BFR resource for sending a BFR from multiple PUCCH-BFR resources is a problem to be solved.

[0027] Therefore, the present disclosure provides a BFR resource allocation method applied to a terminal. The terminal is configured with multiple BFR resources. The multiple BFR resources are composed of PUCCH-BFR resources configured by a serving cell in a group of multiple serving cells configured by the terminal. In other words, the BFR resource allocation method provided by the present disclosure can also be understood as a PUCCH-BFR resource allocation method. When performing PUCCH-BFR resource allocation, it is detected whether there is a SCell that has beam failure. When a SCell that has beam failure is detected, a PUCCH-BFR resource is selected from multiple PUCCH-BFR resources as a PUCCH-BFR resource for sending a BFR, according to whether the SCell is configured with a PUCCH-BFR resource.

[0028] Figure 2 A flowchart of a PUCCH-BFR resource allocation method according to an exemplary embodiment is shown in FIG. 1. Figure 2 As shown in FIG. 1, the PUCCH-BFR resource allocation method is applied to a terminal and includes the following steps.

[0029] In step S11, it is detected whether there is a SCell that has beam failure.

[0030] In the present disclosure, for the convenience of description, the SCell that has beam failure is referred to as a first SCell.

[0031] In the present disclosure, when the first SCell that has beam failure is detected, step S12 can be performed. When the first SCell that has beam failure is not detected, the original communication process can be maintained.

[0032] In step S12, a PUCCH-BFR resource is selected from multiple PUCCH-BFR resources as a PUCCH-BFR resource for sending a BFR, according to whether the first SCell is configured with a PUCCH-BFR resource.

[0033] In the present disclosure, for the convenience of description, the SCell configured with a PUCCH-BFR resource is referred to as a second SCell.

[0034] In the present disclosure, when a secondary cell that has beam failure is detected, a beam failure request resource is selected from multiple beam failure request resources as a resource for sending a beam failure request, according to whether the secondary cell is configured with a beam failure request resource, to achieve determination of the resource for sending a beam failure request from the multiple beam failure request resources.

[0035] The embodiments of the present disclosure will be described below in combination with actual applications to explain the PUCCH-BFR resource allocation process related to the above embodiments.

[0036] In the embodiments of the present disclosure, the terminal configured serving cell group is divided into two categories, one is the serving cell containing PCell / Pscell, referred to as the first serving cell group. The other is the serving cell containing only Scell without PCell / Pscell, referred to as the second serving cell group. Among them, the first serving cell group includes Scell without PUCCH-BFR resource configuration and PCell / Pscell with PUCCH-BFR resource configuration. The second serving cell group includes Scell with PUCCH-BFR resource configuration and Scell without PUCCH-BFR resource configuration. For example, the terminal is configured with PCell / PScell, SCell#1, SCell#2, SCell#3 and SCell#4, and these serving cells are divided into two PUCCH groups, PUCCH group1 contains PCell / PScell, SCell#1, SCell#2, and PUCCH-BFR1 is configured on PCell / PScell. PUCCH group2 contains SCell#3 and SCell#4, and PUCCH-BFR2 is configured on SCell#3.

[0037] In the embodiments of the present disclosure, the PUCCH-BFR resource selection process when the first Scell with beam failure is not configured with PUCCH-BFR resource is first described.

[0038] In the embodiments of the present disclosure, when the first Scell with beam failure is not configured with PUCCH-BFR resource, that is, the SCell with beam failure is not configured with PUCCH-BFR, the terminal has two PUCCH-BFR resources to choose from, one is the PUCCH-BFR resource in the PUCCH group to which the SCell with beam failure belongs, and the other is the PUCCH-BFR resource in another PUCCH group different from the PUCCH group to which the SCell with beam failure belongs.

[0039] In the embodiments of the present disclosure, the terminal can select one PUCCH-BFR resource from the plurality of PUCCH-BFR resources in at least one of the following ways: selecting a PUCCH-BFR resource configured by a serving cell in a PUCCH group to which the first SCell belongs; selecting a PUCCH-BFR resource that appears first in time; selecting a PUCCH-BFR resource that does not need to transmit other uplink information; and selecting a PUCCH-BFR resource that can be multiplexed with other uplink information.

[0040] In the embodiments of the present disclosure, the following is described by taking the case that a terminal is configured with a PCell / PScell, SCell#1, SCell#2, SCell#3 and SCell#4, and these serving cells are divided into two PUCCH groups as an example. The PUCCH group 1 includes the PCell / PScell, SCell#1, SCell#2, and is configured with PUCCH-BFR1 on the PCell / PScell. The PUCCH group 2 includes SCell#3 and SCell#4, and is configured with PUCCH-BFR2 on SCell#3. It is assumed that the SCell in which the terminal detects that beam failure occurs is an SCell that is not configured with a PUCCH-BFR resource, for example, SCell#1, or SCell#2, or SCell#4. The terminal can preferentially select a PUCCH-BFR resource configured by a serving cell in a PUCCH group to which the first SCell belongs. For example, when SCell#4 occurs beam failure, BFR is transmitted using PUCCH-BFR2. When SCell#1 or SCell#2 occurs beam failure, BFR is transmitted using PUCCH-BFR1.

[0041] In the embodiments of the present disclosure, in the case that the beam failure occurs and no PUCCH-BFR resource is configured, the PUCCH-BFR resource configured by the serving cell in the PUCCH group to which the first SCell belongs is preferentially selected, that is, when the SCell in the PUCCH group has the beam failure and the SCell having the beam failure has no PUCCH-BFR, the PUCCH-BFR in the PUCCH group is selected to send the BFR. Therefore, for the PUCCH group not containing the PCell / PSCell, the PUCCH-BFR resource on the SCell configured in the PUCCH group can be preferentially used, and when the SCell configured with the PUCCH-BFR resource in the PUCCH group also has the beam failure, the PUCCH-BFR resource configured on the PCell / PSCell is used, thereby reducing the signaling overhead of the MAC CE.

[0042] Further, since the PUCCH-BFR can be periodic, in the case where the beam failure occurs and the PUCCH-BFR resource is not configured, the following priority can be used for the selection of the PUCCH-BFR resource in the embodiments of the present disclosure. For example, the PUCCH-BFR resource that appears first in time can be selected first. For example, when the terminal detects that the SCell has a beam failure, the first available PUCCH-BFR resource is the PUCCH-BFR1 resource configured on the PUCCH group1, and the terminal uses the PUCCH-BFR1 resource first. Further, the PUCCH-BFR resource that does not need to transmit other uplink information (such as a sounding reference signal (SRS), a scheduling request (SR), a hybrid automatic repeat request (HARQ), and a channel state information reference signal (CSI-RS)) can be selected first in the embodiments of the present disclosure. It should be noted that the PUCCH resource where the PUCCH-BFR resource is located does not need to be used to transmit other uplink information, that is, in the time of the PUCCH resource, no other uplink information needs to be transmitted on the PUCCH resource, except that the beam failure request needs to be transmitted. Further, if two or more PUCCH-BFR resources have other uplink information to be transmitted, that is, the time of the PUCCH resource where the PUCCH-BFR resource is located has other uplink information to be transmitted on the PUCCH resource, the PUCCH-BFR resource that can be multiplexed with other uplink information can be used first in the embodiments of the present disclosure, so that the BFR and other uplink information can be transmitted, and other uplink information is not discarded as much as possible, that is, a PUCCH resource that can accommodate other uplink information in addition to the beam failure information on the PUCCH-BFR is selected, for example, the PUCCH resource can support more bits. If it is necessary to discard some other uplink information, the other uplink information can be sequentially discarded according to the priority of the CSI-RS, the SRS, the HARQ, and the SR from high to low.

[0043] In the embodiments of the present disclosure, in the case that the beam failure occurs and the PUCCH-BFR resource is configured, the PUCCH-BFR resource configured by the serving cell in the other serving cell group different from the first SCell belonging to the serving cell group can be selected. In other words, when the SCell in the PUCCH group occurs beam failure, and the SCell that occurs beam failure is the SCell configured with the PUCCH-BFR, the PUCCH-BFR in the other PUCCH group is selected to send the BFR. For example, in the above example, when the SCell#3 occurs beam failure, the BFR is sent by using the PUCCH-BFR1.

[0044] In the above embodiments of the present disclosure, the terminal can select one PUCCH-BFR resource from the plurality of PUCCH-BFR resources to send the BFR. After the terminal sends the BFR to the network device by using the selected PUCCH-BFR resource, the PUSCH resource can be requested, and then the MAC CE signaling is sent on the requested PUSCH resource to indicate whether the SCell in the PUCCH group configured by the terminal occurs beam failure.

[0045] Figure 3 A flowchart of a PUCCH-BFR resource allocation method according to an exemplary embodiment is shown in FIG. 6. Figure 2 As shown in FIG. 6, the PUCCH-BFR resource allocation method is used in the terminal, and includes steps S21, S22 and S23.

[0046] The steps S21 and S22 are the same as the steps S11 and S12, and will not be described here.

[0047] In step S23, the MAC CE is sent on the PUSCH resource requested by using the selected PUCCH-BFR resource, and the MAC CE is used to indicate whether the SCell in the PUCCH group configured by the terminal occurs beam failure.

[0048] In the embodiments of the present disclosure, according to whether the PUCCH-BFR resource selected by the terminal is the PUCCH-BFR resource configured on the second SCell, the MAC CE can indicate whether the SCell in all or part of the serving cell group configured by the terminal occurs beam failure.

[0049] In the embodiments of the present disclosure, when the PUCCH-BFR resource selected by the terminal is the PUCCH-BFR resource on the second Scell, it can be understood that the PUCCH-BFR resource on the Scell is used to report whether the beam failure occurs on the SCell. The network device receiving the BFR sent by using the PUCCH-BFR resource on the second Scell can determine that the SCell on which the beam failure occurs is the SCell belonging to the same PUCCH group as the second Scell. Therefore, at this time, the MAC CE can be used to indicate whether the beam failure occurs on each SCell in the PUCCH group to which the second Scell belongs except the second Scell, without the need to indicate whether the beam failure occurs on the SCell in the other PUCCH group, thereby reducing the signaling overhead of the MAC CE. Further, when a new beam is detected in the SCell on which the beam failure occurs, the index of the new beam can be indicated by the MAC CE.

[0050] For example, in the above example, only SCell#4 is in PUCCH group2 except SCell#3, then only the index of SCell#4 and the new beam index need to be indicated. It can be understood that since there is only one SCell in PUCCH group2 except SCell#3, actually the serving cell index does not need to be indicated, only the new beam index needs to be indicated. But assuming PUCCH group2 contains SCell#3, SCell#4 and SCell#5, and PUCCH-BFR2 is configured in SCell#3, then the MAC CE needs to first indicate whether a beam failure occurs for SCell#4 and SCell#5 respectively, and then if a beam failure occurs, the corresponding new beam index is indicated. For example, SCell#4 and SCell#5 use 1 bit to indicate whether a beam failure occurs, and the bit shows '1' to indicate that a beam failure occurs, and shows '0' to indicate that no beam failure occurs. The meanings of '0' and '1' can also be exchanged. For the corresponding relationship between the 2-bit bit and SCell#4 and SCell#5, the high bit corresponds to the smaller cell index, i.e. SCell#4, and the low bit corresponds to the larger cell index, i.e. SCell#5. Of course, the high bit can correspond to the larger cell index, i.e. SCell#5, and the low bit can correspond to the smaller cell index, i.e. SCell#4.

[0051] In the embodiments of the present disclosure, when the PUCCH-BFR resource selected by the terminal is the PUCCH-BFR resource of the PCell / PSCell, for example, when the SCell configured with the PUCCH-BFR occurs beam failure, the terminal selects to send the BFR on the PUCCH-BFR of the PCell / PSCell. When the SCell occurring beam failure is in the same PUCCH group as the PCell / PSCell, the terminal also selects to send the BFR on the PUCCH-BFR of the PCell / PSCell. Therefore, when the network device receives the PUCCH-BFR of the PCell / PSCell, it does not know whether the SCell occurring beam failure is the SCell in the PUCCH group 1 or the PUCCH group 2. Therefore, when the MAC CE indicates the index of the SCell occurring beam failure, it needs to indicate whether each SCell in all the PUCCH groups configured by the terminal is beam failure. That is, the terminal needs to indicate whether each SCell in all the SCells is beam failure and, for the SCell occurring beam failure, whether a new beam is detected and the corresponding new beam index in the MAC CE sent on the PUSCH resource requested by using the PUCCH-BFR resource of the PCell / PSCell.

[0052] For example, in the above example, PUCCH-BFR1 not only needs to be used to indicate that SCell#3 has beam failure, but also can be used to indicate that SCell#4 or SCell#5 has beam failure. That is, PUCCH-BFR1 indicates that the SCell in PUCCH group1 has beam failure, or the SCell in PUCCH group2 has beam failure. Therefore, the MAC CE for PUCCH-BFR1 needs to indicate whether each SCell in all SCells has beam failure and the corresponding new beam index (if beam failure occurs and a new beam is detected) in addition to the PCell / PScell. Similarly, for the above example, for example, the terminal is configured with PCell / PScell, SCell#1, SCell#2, SCell#3 and SCell#4, and the MAC CE for SCell#1, SCell#2, SCell#3 and SCell#4, each SCell has 1 bit to indicate whether the SCell has beam failure. The bit shows '1' to identify that beam failure occurs, and shows '0' to indicate that beam failure does not occur. Similarly, the identification meaning of '0' and '1' can be exchanged. For the correspondence between the 4-bit bit and SCell#1, SCell#2, SCell#3 and SCell#4, the highest bit can correspond to the cell index that is the smallest, that is, SCell#1, and the lowest bit can correspond to the cell index that is the largest, that is, SCell#4. Of course, the highest bit can correspond to the cell index that is the largest, that is, SCell#4, and the lowest bit can correspond to the cell index that is the smallest, that is, SCell#1. If beam failure occurs and a new beam is detected, the corresponding new beam index on the SCell also needs to be indicated.

[0053] The PUCCH-BFR resource allocation method provided by the above embodiments of the present disclosure enables determination of a PUCCH-BFR resource for sending a BFR by a terminal among multiple PUCCH-BFR resources. Moreover, when a terminal is configured with multiple PUCCH-BFRs, the selection method of a PUCCH-BFR in the case of SCell beam failure mainly uses the corresponding PUCCH-BFR through a PUCCH group, and only when the SCell configured with the PUCCH-BFR in the PUCCH group also experiences beam failure, the PUCCH-BFR configured on the PCell / PSCell is used, otherwise the PUCCH-BFR in the PUCCH group is used, thereby reducing the signaling overhead of MAC CE in step 2.

[0054] Based on the same concept, the present disclosure also provides a PUCCH-BFR resource allocation apparatus.

[0055] It can be understood that the PUCCH-BFR resource allocation apparatus provided by the embodiments of the present disclosure comprises a hardware structure and / or software module for executing each function in order to achieve the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiments of the present disclosure, the embodiments of the present disclosure can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is realized by hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to realize the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of the embodiments of the present disclosure.

[0056] Figure 4 is a block diagram of a PUCCH-BFR resource allocation apparatus according to an exemplary embodiment. Referring to Figure 4 The PUCCH-BFR resource allocation apparatus 100 comprises a detection unit 101 and a selection unit 102.

[0057] The detection unit 101 is configured to detect whether there is a first Scell that experiences beam failure. The selection unit 102 is configured to, when the detection unit detects a first Scell that experiences beam failure, select one PUCCH-BFR resource as a resource for sending a beam failure request among multiple PUCCH-BFR resources according to whether the first Scell is configured with a PUCCH-BFR resource.

[0058] In one embodiment, when the first Scell is not configured with PUCCH-BFR resource, the selecting unit 102 selects one PUCCH-BFR resource from the plurality of PUCCH-BFR resources in the following at least one way:

[0059] selecting a PUCCH-BFR resource configured by a serving cell in a serving cell group to which the first Scell belongs; selecting a PUCCH-BFR resource that appears earliest in time; selecting a PUCCH-BFR resource that does not need to transmit other uplink information; and selecting a PUCCH-BFR resource that can be multiplexed with other uplink information.

[0060] In another embodiment, when the first Scell is configured with PUCCH-BFR resource, the selecting unit 102 selects a PUCCH-BFR resource configured by a serving cell in another serving cell group different from the serving cell group to which the first Scell belongs.

[0061] In yet another embodiment, the PUCCH-BFR resource allocation apparatus 100 further comprises a sending unit 103.

[0062] The sending unit 103 is configured to send the BFR using the selected PUCCH-BFR resource to request PUSCH resource.

[0063] The sending unit 103 is further configured to send a medium access control information unit using the physical uplink shared channel resource requested by the selected PUCCH-BFR resource, the medium access control information unit being used to indicate whether beam failure occurs in each Scell in the serving cell group configured by the terminal.

[0064] In yet another embodiment, the selected PUCCH-BFR resource is a PUCCH-BFR resource configured on a primary cell or a primary Scell. The medium access control information unit is used to indicate whether beam failure occurs in each Scell in all the serving cell groups configured by the terminal.

[0065] In yet another embodiment, the selected PUCCH-BFR resource is a PUCCH-BFR resource configured on a second Scell. The medium access control information unit is used to indicate whether beam failure occurs in each Scell in the serving cell group to which the second Scell belongs except the second Scell.

[0066] In yet another embodiment, if it is determined that there is a new beam in the first Scell, the medium access control information unit is further used to indicate the new beam.
