[0025] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0026] Figure 1 A block diagram of a communication system provided by an exemplary embodiment of the present disclosure is shown. The communication system may include: a core network 11, an access network 12 and a terminal 13.

[0027] The core network 11 includes several core network devices 110. The core network device 110 includes devices such as Access and Mobility Management Function (AMF), Session Management Function (SMF) and User Plane Function (UPF), among which AMF is used to control the access authority and switching functions of the terminal, and SMF is used to provide server continuity and uninterrupted user experience of the server, such as: IP address and anchor point changes.

[0028] The access network 12 includes several access network devices 120. The access network device 120 may be a base station, which is a device deployed in the access network to provide wireless communication functions for terminals. Base stations may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the Long Term Evolution (LTE) system, it is called eNodeB or eNB; in the 5G New Radio (NR) system, it is called gNode B or gNB. With the evolution of communication technology, the name "base station" may be described and may change. For the convenience of the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for terminals are collectively referred to as access network devices.

[0029] The terminal 13 may include various handheld devices with wireless communication functions, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, as well as various forms of terminals (User Equipment, UE), mobile stations (Mobile Station, MS), terminals (terminal devices), etc. For the convenience of description, the above-mentioned devices are collectively referred to as terminals. The access network device 120 and the terminal 13 communicate with each other through some air interface technology, such as a Uu interface.

[0030] Optionally, in the process of wireless communication between the terminal 13 and the access network device 120, wireless communication can be performed through an authorized frequency band or through an unauthorized frequency band. Optionally, in the embodiment of the present disclosure, wireless communication between the terminal 13 and the access network device 120 through an unauthorized frequency band is used as an example for description.

[0031] Currently, 3GPP is discussing support for extending NR supported frequencies from up to 52.6GHz to up to 71GHz. The frequency range of 52.6GHz-71GHz includes the unlicensed band of 60GHz. This band will adopt NR-U (NR-Unlicensed) technology, the main feature of which is that UE and gNB need to perform LBT (Listen-before-talk) before sending, and can only send data after detecting that the channel is idle. The sender generally needs to monitor the channel before sending a communication message. Only after the channel monitoring is successful, that is, it is determined that the monitored channel is not occupied by other senders, can the communication message be sent on the channel, which is the channel occupancy mechanism of LBT.

[0032] The transmitter performs channel monitoring with an LBT band (bandwidth) as a frequency unit. Schematically, an LBT band is 20 MHz. The uplink resources configured by the base station for the UE, that is, the uplink bandwidth part (BandWith Part, BWP) may include one or more LBT bands.

[0033] When monitoring LBT failure, the UE monitors at the granularity of BWP. If a continuous LBT failure is detected on a BWP of a serving cell (ServingCell), that is, the result of LBT channel monitoring is continuously a monitoring failure result, the UE will switch to another BWP of the serving cell configured with physical random access channel (PRACH) resources to initiate random access. At the same time, if the UE has available uplink carrier resources, an LBT failure media access control (Media Access Control, MAC) CE (Control Element) is generated, and the MAC CE will indicate the identities of all serving cells where LBT failure occurs. If the UE tries all BWPs of the serving cell and continuous LBT failure occurs, and if the serving cell is a special cell (SpecialCell, SpCell), the UE MAC layer indicates LBT failure to the radio resource control (Radio Resource Control, RRC) layer, and the UE indicates a radio link failure (Radio Link Failure, RLF) of the master cell group (Master Cell Group, MCG) / secondary cell group (Secondary Cell Group, SCG).

[0034] Among them, the judgment method of continuous LBT failure is as follows:

[0035] Each time the UE MAC layer receives an LBT failure instance indicated by the physical layer (PHY), the LBT counter (LBT_COUNTER) is incremented by 1 and the timer lbt-FailureDetectionTimer (representing the duration for which the LBT failure instance has not been received) is restarted.

[0036] When LBT_COUNTER ≥ lbt-FailureInstanceMaxCount (maximum count threshold), the continuous LBT failure of the current active BWP is triggered. When the UE changes the BWP, it will set LBT_COUNTER to 0 and stop lbt-FailureDetectionTimer. When lbt-FailureDetectionTimer times out, it means that no LBTfailure instance has been received for a period of time, then it is considered that the channel has improved and the LBT_COUNTER is cleared.

[0037] For the unlicensed frequency band, that is, the 60 GHz high frequency band, a very narrow beam can be used for communication transmission and reception, and the LBT situation in the direction of the beam will not affect the transmission, so there is no need for omnidirectional LBT monitoring.

[0038] To this end, 3GPP is discussing the introduction of directional LBT, that is, LBT is not omnidirectional monitoring, but only monitoring in a specific direction. The UE transmit beam and the sensing beam that monitors LBT include at least one of the following relationships: 1. One transmit beam corresponds to one sensing beam or beam set; 2. One sensing beam corresponds to one transmit beam or beam set. Among them, the beam width of the sensing beam or beam set mapped by the transmit beam needs to at least cover the beam width of the transmit beam.

[0039] In the related art, the judgment of continuous LBT failure is made within a BWP, and all beam directions are taken into account. Obviously, after the introduction of directional LBT, it is not appropriate to judge continuous LBT failure based on omnidirectional LBT failure. For example: according to the relevant protocol, when the physical layer detects LBT failure in one beam direction, it indicates the LBT failure instance to the MAC layer, and the MAC layer will increase the LBT_COUNTER count by 1; then, when the physical layer changes the beam monitoring direction, LBT failure occurs again, indicating the LBT failure instance to the MAC layer, and the MAC layer will increase the LBT_COUNTER count by 1. However, the two LBT failure instances come from two different LBT monitoring directions. By superimposing and counting the LBT times in multiple directions, it is obviously impossible to correctly determine which LBT monitoring direction actually has a continuous LBT failure.

[0040] In an embodiment of the present application, the LBT counter or timer is updated according to the sensing beam or beam set corresponding to the transmitting beam.

[0041] Figure 2 is a flow chart of a communication method provided by an exemplary embodiment of the present disclosure, wherein the method is applied to Figure 1 The terminal shown in FIG. 1 is used as an example to illustrate. Figure 2 As shown, the method includes:

[0042] Step 201, determining a listen-before-talk (LBT) channel monitoring result.

[0043] Optionally, the channel monitoring result of LBT includes channel monitoring success or channel monitoring failure, wherein channel monitoring success is used to indicate that the channel monitored by LBT is idle and communication transmission is possible; channel monitoring failure is used to indicate that the channel monitored by LBT is busy and communication transmission is not possible.

[0044] Optionally, the physical layer monitors the LBT channel in a beam direction and indicates the LBT channel monitoring result to the MAC layer.

[0045] Step 202: Update the LBT counter according to the channel monitoring result and the corresponding sensing beam identifier or beam set identifier.

[0046] Optionally, since one transmitting beam corresponds to one sensing beam or one transmitting beam corresponds to one beam set, when one transmitting beam corresponds to one sensing beam, the LBT counter is updated according to the channel monitoring result and the corresponding sensing beam identifier; when one transmitting beam corresponds to one beam set, the LBT counter is updated according to the channel monitoring result and the corresponding beam set identifier.

[0047] Step 203: Update the timer according to the channel monitoring result and the corresponding sensing beam identifier or beam set identifier.

[0048] Optionally, since one transmitting beam corresponds to one sensing beam or one transmitting beam corresponds to one beam set, when one transmitting beam corresponds to one sensing beam, the timer is updated according to the channel monitoring result and the corresponding sensing beam identifier; when one transmitting beam corresponds to one beam set, the timer is updated according to the channel monitoring result and the corresponding beam set identifier.

[0049] In the embodiment of the present application, an example is taken where one transmission beam corresponds to one sensing beam or beam set.

[0050] Optionally, the LBT counter and / or timer is updated accordingly based on the channel monitoring result and the perception beam or beam set corresponding to the channel monitoring result.

[0051] Optionally, after receiving the channel monitoring result indicated by the physical layer, the MAC layer updates the LBT counter and / or timer according to the channel monitoring result and the corresponding perception beam identifier or beam set identifier.

[0052] To summarize, the embodiments of the present application synchronously determine the sensing beam or beam set corresponding to the LBT channel monitoring result during the LBT channel monitoring result, thereby determining whether the beam corresponding to the channel monitoring result has changed, avoiding the problem of low LBT accuracy caused by different beam corresponding counts or timings on the same counter / timer, and solving the counting / timing of directional LBT.

[0053] In the embodiments of the present application, the schemes for updating the counter / timer according to the channel monitoring results and the corresponding sensing beam identifier or beam set identifier are described respectively.

[0054] 1. Reset counter and / or stop timer solution

[0055] Figure 3 is a flow chart of a communication method provided by an exemplary embodiment of the present application, wherein the method is applied to Figure 1 The terminal shown in FIG. 1 is used as an example to illustrate. Figure 3 As shown, the method includes:

[0056] Step 301, determining a channel monitoring result of the listen-before-talk (LBT) method.

[0057] Optionally, the channel monitoring result of LBT includes channel monitoring success or channel monitoring failure, wherein channel monitoring success is used to indicate that the channel monitored by LBT is idle and communication transmission is possible; channel monitoring failure is used to indicate that the channel monitored by LBT is busy and communication transmission is not possible.

[0058] Step 302: In response to a change in a sensing beam identifier or a beam set identifier corresponding to a channel monitoring result, the LBT counter is reset to zero.

[0059] That is, if the sensing beam or beam set changes, set LBT_COUNTER=0.

[0060] Step 303: In response to a change in a sensing beam identifier or a beam set identifier corresponding to a channel monitoring result, stop the timer.

[0061] That is, if the sensing beam or beam set changes, stop lbt-FailureDetectionTimer.

[0062] The above setting of LBT_COUNTER=0 and stopping of lbt-FailureDetectionTimer can be implemented either one or both, that is, the above steps 302 and 303 can only execute step 302, can only execute step 303, or can execute both steps 302 and 303 at the same time, which is not limited in this embodiment. That is, if the sensing beam or beam set changes, one or more of the following operations are performed: 1. Setting LBT_COUNTER=0; 2. Stopping lbt-FailureDetectionTimer.

[0063] Among them, the change of the sensing beam or beam set means that the sensing beam identifier or beam set identifier targeted by the LBT channel monitoring is different from the sensing beam identifier or beam set identifier corresponding to the channel monitoring result, and it is determined that the sensing beam or beam set has changed.

[0064] That is, during the LBT channel monitoring process, there is an identification indication of the currently targeted perception beam or beam set, so that according to the perception beam identification or beam set identification corresponding to the received channel monitoring result, it can be determined whether the perception beam or beam set has changed.

[0065] Optionally, determining whether the sensing beam or beam set changes may be performed by at least one of the following situations:

[0066] First, when the transmission beam of the listen-before-speak LBT is switched from the first beam to the second beam, and the perception beam or beam set corresponding to the first beam is different from the perception beam or beam set corresponding to the second beam, it is determined that the perception beam or beam set has changed.

[0067] That is, the UE's transmit beam is switched from beam 1 to beam 2, and the sensing beam or beam set corresponding to beam 2 is different from the sensing beam or beam set corresponding to beam 1.

[0068] Second, when the perception beam or beam set corresponding to the transmit beam of the listen-before-speak LBT is switched from the first perception beam or beam set to the second perception beam or beam set, it is determined that the perception beam identifier or beam set identifier changes.

[0069] That is, the UE's transmit beam remains unchanged, but the sensing beam or beam set corresponding to the transmit beam is switched to a new sensing beam or beam set.

[0070] Optionally, in the scheme of resetting the counter and / or stopping the timer, at least one of the following implementations is included:

[0071] 1.1 The channel monitoring result of each LBT includes the corresponding sensing beam identifier or beam set identifier;

[0072] That is, no matter whether the channel monitoring result obtained by the physical layer in the beam direction is a successful channel monitoring or a failed channel monitoring, the physical layer will indicate the perception beam identifier or beam set identifier corresponding to the channel monitoring result to the MAC layer. The MAC layer will then determine whether the perception beam or beam set targeted by the current channel monitoring has changed based on the perception beam identifier or beam set identifier corresponding to the channel monitoring result, and update the LBT counter and / or timer based on the change of the perception beam or beam set.

[0073] Wherein, updating the LBT counter and / or timer according to the change of the sensing beam or beam set includes at least one of the following situations:

[0074] The first , channel monitoring is successful, and the sensing beam identifier or beam set identifier has not changed;

[0075] That is, on the LBT monitoring channel, if the channel monitoring is successful, communication transmission can be carried out, and the sensing beam or beam set has not changed, the LBT counter does not need to be increased and / or the timer continues to count.

[0076] Optionally, when the channel monitoring is successful and the perception beam identifier or the beam set identifier has not changed, the physical layer does not need to indicate the perception beam identifier or the beam set identifier to the MAC layer; or, when the channel monitoring is successful and the perception beam identifier or the beam set identifier has not changed, the physical layer indicates the perception beam identifier or the beam set identifier to the MAC layer, but the MAC layer recognizes that the perception beam or beam set has not changed, and controls the LBT counter to not increase and / or the timer to continue timing.

[0077] Optionally, when the timing duration of the timer reaches a timing threshold, the timer is reset to zero, indicating that the channel monitoring result corresponding to the current LBT channel monitoring does not fail within the timing threshold, that is, the quality of the channel monitored by LBT is good, and the LBT timer is cleared at the same time.

[0078] The second , channel monitoring is successful, and the beam identifier or beam set identifier changes;

[0079] That is, on the LBT monitoring channel, the channel monitoring is successful, but because the perception beam identifier or beam set identifier changes, that is, the perception beam or beam set targeted by the current LBT channel monitoring is different from the perception beam or beam set for which the channel monitoring is successful, the LBT counter is set to zero and / or the timer is stopped.

[0080] Optionally, when channel monitoring is successful and the sensing beam identifier or beam set identifier changes, the physical layer indicates the sensing beam identifier or beam set identifier to the MAC layer, the MAC layer recognizes that the sensing beam or beam set has changed, and controls the LBT counter to be reset to zero and / or stops the timer.

[0081] Optionally, since the sensing beam or beam set changes, the MAC layer updates and replaces the sensing beam or beam set targeted by the current LBT channel monitoring with the sensing beam or beam set corresponding to the most recent channel monitoring result.

[0082] The third , channel monitoring failed, and the sensing beam identifier or beam set identifier did not change;

[0083] That is, if channel monitoring fails on the LBT monitoring channel, the LBT monitoring channel cannot communicate, and the sensing beam or beam set has not changed, the LBT counter counts up by 1 and / or the timer restarts the timing process according to the LBT failureinstance indicated by the channel monitoring failure.

[0084] Optionally, when channel monitoring fails and the perception beam identifier or the beam set identifier has not changed, the physical layer does not need to indicate the perception beam identifier or the beam set identifier to the MAC layer, and only indicates the LBT failure instance to the MAC layer; alternatively, when channel monitoring fails and the perception beam identifier or the beam set identifier has not changed, the physical layer indicates the LBT failure instance and the perception beam identifier or the beam set identifier to the MAC layer, but the MAC layer recognizes that the perception beam or the beam set has not changed, and controls the LBT counter to count up by 1 and / or restart the timer according to the LBT failure instance.

[0085] The fourth , channel monitoring failed, and the sensing beam identifier or beam set identifier changed.

[0086] That is, channel monitoring fails on the LBT monitoring channel, the LBT monitoring channel cannot carry out communication transmission, and the sensing beam or beam set changes, that is, the sensing beam or beam set targeted by the current LBT channel monitoring is different from the sensing beam or beam set where the channel monitoring fails, so the LBT counter is set to zero and / or the timer is stopped.

[0087] Optionally, when channel monitoring fails and the sensing beam identifier or beam set identifier changes, the physical layer indicates the LBT failure instance and the sensing beam identifier or beam set identifier to the MAC layer. The MAC layer recognizes that the sensing beam or beam set has changed, and controls the LBT counter to be reset to zero and / or stops the timer.

[0088] Optionally, since the sensing beam or beam set changes, the MAC layer updates and replaces the sensing beam or beam set targeted by the current LBT channel monitoring with the sensing beam or beam set corresponding to the most recent channel monitoring result.

[0089] When the LBT counter reaches a count threshold, it is determined that the continuous LBT failure of the sensing beam or beam set targeted by the current LBT channel monitoring occurs.

[0090] Optionally, if all candidate sensing beams or beam sets on the current active BWP trigger continuous LBT failure, the current BWP is triggered to fail continuously LBT, and the BWP is replaced to perform LBT channel monitoring.

[0091] Optionally, when it is determined that the continuous LBT of the current sensing beam or beam set fails, the random access process is triggered.

[0092] Optionally, when determining that the current sensing beam or beam set has a persistent LBT failure, the UE generates LBT failure indication information, such as MAC CE, and the indication information is used to indicate the sensing beam or beam set where the LBT failure occurs. Schematically, the indication information includes the sensing beam identifier or beam set identifier where the LBT failure occurs, and optionally, the indication information also includes the current active BWP identifier and / or serving cell identifier.

[0093] When the duration of the timer reaches the timing threshold, the timer is reset to zero, indicating that the channel monitoring result corresponding to the current LBT channel monitoring does not fail within the timing threshold, that is, the quality of the channel monitored by LBT is good, and the LBT timer is cleared at the same time.

[0094] 1.2 In response to the LBT channel monitoring result, the LBT channel monitoring result is used to indicate that the channel monitoring has failed. There is a sensing beam identifier or a beam set identifier.

[0095] That is, only when the channel monitoring result detected by the physical layer in the beam direction is a channel monitoring failure, the physical layer indicates to the MAC layer the perception beam identifier or beam set identifier corresponding to the channel monitoring failure. The MAC layer then determines whether the perception beam or beam set targeted by the statistics of the current LBT counter / timer has changed based on the perception beam identifier or beam set identifier corresponding to the channel monitoring failure, and updates the LBT counter and / or timer based on the change of the perception beam or beam set.

[0096] Wherein, updating the LBT counter and / or timer according to the change of the sensing beam or beam set includes at least one of the following situations:

[0097] The first , the sensing beam identifier or beam set identifier has not changed;

[0098] That is, if channel monitoring fails on the LBT monitoring channel, the LBT monitoring channel cannot communicate, and the sensing beam or beam set has not changed, the LBT counter counts up by 1 and / or the timer restarts the timing process according to the LBT failureinstance indicated by the channel monitoring failure.

[0099] The second , sensing beam identifier or beam set identifier changes.

[0100] That is, channel monitoring fails on the LBT monitoring channel, the LBT monitoring channel cannot carry out communication transmission, and the perception beam or beam set changes, that is, the perception beam or beam set targeted by the current LBT channel monitoring is different from the perception beam or beam set at the time of the most recent channel monitoring failure, so the LBT counter is set to zero and / or the timer is stopped.

[0101] Optionally, since the sensing beam or beam set changes, the MAC layer updates and replaces the sensing beam or beam set targeted by the current LBT channel monitoring with the sensing beam or beam set corresponding to the most recent channel monitoring result.

[0102] When the LBT counter reaches a count threshold, it is determined that the continuous LBT failure of the sensing beam or beam set targeted by the current LBT channel monitoring occurs.

[0103] Optionally, if all candidate sensing beams or beam sets on the current active BWP trigger continuous LBT failure, the current BWP is triggered to fail continuously LBT, and the BWP is replaced to perform LBT channel monitoring.

[0104] Optionally, when it is determined that the continuous LBT of the current sensing beam or beam set fails, the random access process is triggered.

[0105] Optionally, when determining that the current sensing beam or beam set has a persistent LBT failure, the UE generates LBT failure indication information, such as MAC CE, and the indication information is used to indicate the sensing beam or beam set where the LBT failure occurs. Schematically, the indication information includes the sensing beam identifier or beam set identifier where the LBT failure occurs, and optionally, the indication information also includes the current active BWP identifier and / or serving cell identifier.

[0106] When the timer reaches the timing threshold, the timer is reset to zero, indicating that the channel monitoring result corresponding to the current LBT channel monitoring does not fail within the timing threshold, that is, the quality of the channel monitored by LBT is good, and the LBT counter is reset to zero.

[0107] For counters:Optionally, in the above-mentioned reset counter and / or stop timer scheme, only one LBT counter is used at a time, that is, the LBT counter for the current sensing beam or beam set; or, the LBT counter includes a first LBT counter corresponding to a physical uplink control channel (PUCCH) and a second LBT counter corresponding to a physical uplink shared channel (PUSCH); wherein the first LBT counter and the second LBT counter count respectively corresponding to PUCCH and PUSCH. Optionally, PUCCH and PUSCH respectively correspond to their own sensing beams or beam sets.

[0108] In schematic form, when the received channel monitoring result is a channel failure result corresponding to PUCCH, and the perception beam identifier or beam set identifier corresponding to the PUCCH changes, the first LBT counter corresponding to the PUCCH is reset to zero; when the received channel monitoring result is a channel failure result corresponding to PUCCH, and the perception beam identifier or beam set identifier corresponding to the PUCCH does not change, the first LBT counter corresponding to the PUCCH is counted and added by 1; when the received channel monitoring result is a channel failure result corresponding to PUSCH, and the perception beam identifier or beam set identifier corresponding to the PUSCH changes, the second LBT counter corresponding to the PUSCH is reset to zero; when the received channel monitoring result is a channel failure result corresponding to PUSCH, and the perception beam identifier or beam set identifier corresponding to the PUSCH does not change, the second LBT counter corresponding to the PUSCH is counted and added by 1.

[0109] For the timer: Optionally, in the above-mentioned reset counter and / or stop timer scheme, only one timer is used at a time, that is, a timer for the current sensing beam or beam set; or, the timer includes a first timer corresponding to PUCCH and a second timer corresponding to PUSCH; wherein the first timer and the second timer are respectively corresponding to PUCCH and PUSCH. Optionally, PUCCH and PUSCH respectively correspond to their own sensing beams or beam sets.

[0110] In schematic form, when the received channel monitoring result is a channel failure result corresponding to PUCCH, and the perception beam identifier or beam set identifier corresponding to the PUCCH changes, the first timer corresponding to the PUCCH stops timing; when the received channel monitoring result is a channel failure result corresponding to PUCCH, and the perception beam identifier or beam set identifier corresponding to the PUCCH does not change, the first timer corresponding to the PUCCH is restarted; when the received channel monitoring result is a channel failure result corresponding to PUSCH, and the perception beam identifier or beam set identifier corresponding to the PUSCH changes, the second timer corresponding to the PUSCH stops timing; when the received channel monitoring result is a channel failure result corresponding to PUSCH, and the perception beam identifier or beam set identifier corresponding to the PUSCH does not change, the second timer corresponding to the PUSCH is restarted.

[0112] Figure 4 is a flow chart of a communication method provided by an exemplary embodiment of the present application, wherein the method is applied to Figure 1 The terminal shown in FIG. 1 is used as an example to illustrate. Figure 4 As shown, the method includes:

[0113] Step 401, determining a channel monitoring result of the listen-before-talk (LBT) method.

[0114] Optionally, the channel monitoring result of LBT includes channel monitoring success or channel monitoring failure, wherein channel monitoring success is used to indicate that the channel monitored by LBT is idle and communication transmission is possible; channel monitoring failure is used to indicate that the channel monitored by LBT is busy and communication transmission is not possible.

[0115] Step 402: Update the LBT counter corresponding to at least one sensing beam identifier or beam set identifier according to the channel monitoring result.

[0116] That is, according to the channel monitoring result, the LBT counters corresponding to at least one sensing beam identifier or beam set identifier are updated, wherein different sensing beam identifiers or beam set identifiers correspond to different LBT counters.

[0117] In some embodiments, the LBT counter corresponding to the sensing beam identifier or beam set identifier corresponding to the channel monitoring result is updated. That is, the channel monitoring result corresponds to the sensing beam identifier or beam set identifier, and there is also a corresponding relationship between the sensing beam identifier or beam set identifier and the LBT counter. According to the corresponding relationship between the sensing beam identifier or beam set identifier and the LBT counter, the counting process of the corresponding LBT counter is updated.

[0118] Optionally, the UE includes a list of LBT counters corresponding to the sensing beam identifier or the beam set identifier, such as:

[0119] sensing beam1 / beam set1 corresponds to LBT_COUNTERa

[0120] sensing beam2 / beam set2 corresponds to LBT_COUNTERb

[0121] sensing beam3 / beam set3 corresponds to LBT_COUNTERc

[0122] Then, according to the channel monitoring result and the sensing beam identifier or beam set identifier corresponding to the channel monitoring result, the LBT counter corresponding to the sensing beam identifier or beam set identifier is updated.

[0123] In some embodiments, when the channel monitoring result is used to indicate that the channel monitoring has failed, the LBT counter corresponding to the sensing beam identifier or the beam set identifier is counted and increased by 1.

[0124] When the LBT counter count corresponding to a sensing beam identifier or a beam set identifier reaches a count threshold, it is determined that the continuous LBT of the sensing beam identifier or the beam set identifier has failed.

[0125] Optionally, if all candidate sensing beams or beam sets on the current active BWP trigger continuous LBT failure, the current BWP is triggered to fail continuously LBT, and the BWP is replaced to perform LBT channel monitoring.

[0126] Optionally, when it is determined that the continuous LBT of the sensing beam or beam set fails, the random access procedure is triggered.

[0127] Optionally, when determining that the perception beam or beam set has a persistent LBT failure, the UE generates LBT failure indication information, such as MAC CE, and the indication information is used to indicate the perception beam or beam set where the LBT failure occurs. The UE reports the indication information through uplink resources, and illustratively, the indication information includes the perception beam identifier or beam set identifier where the LBT failure occurs, and optionally, the indication information also includes the current active BWP identifier and / or serving cell identifier.

[0128] Optionally, when the UE currently has available uplink resources and the uplink resources can accommodate the indication information, the indication information is reported through the uplink resources, such as: the uplink resources can accommodate the MAC CE and the MAC CE subheader.

[0129] In some embodiments, the indication information also includes a monitoring channel corresponding to the persistent LBT failure, and the monitoring channel includes PUCCH or PUSCH.

[0130] Optionally, when the sensing beam / beam set identifiers corresponding to the PUCCH and PUSCH channels are different, the indication information includes or does not include the monitoring channel corresponding to the continuous LBT failure.

[0131] sensing beam1 / beam set1 corresponds to LBT_COUNTERa

[0132] sensing beam2 / beam set2 corresponds to LBT_COUNTERb

[0133] sensing beam3 / beam set3 corresponds to LBT_COUNTERc

[0134] Among them, sensing beam1 / beam set1 is the sensing beam identifier or beam set identifier corresponding to PUCCH, sensing beam2 / beam set2 and sensing beam3 / beam set3 are the sensing beam identifier or beam set identifier corresponding to PUSCH. By including the sensing beam identifier or beam set identifier in the indication information, the channel type where the continuous LBT failure occurs can be obtained.

[0135] Optionally, after a continuous LBT failure occurs in a sensing beam / beam set, a random access procedure is triggered, as well as a report of an LBT failure MAC CE, which also indicates whether it is a PUCCH LBT failure or a PUSCH LBT failure. BWP continuous LBT failure is triggered after all PUCCH sensing beams / beam sets have continuous LBT failures; and / or, BWP continuous LBT failure is also triggered after all PUSCH sensing beams have continuous LBT failures.

[0136] Step 403: Update a timer corresponding to at least one sensing beam identifier or beam set identifier according to the channel monitoring result.

[0137] That is, according to the channel monitoring result, a timer corresponding to at least one sensing beam identifier or beam set identifier is updated, wherein different sensing beam identifiers or beam set identifiers correspond to different timers.

[0138] In some embodiments, the timer corresponding to the sensing beam identifier or beam set identifier corresponding to the channel monitoring result is updated. That is, the channel monitoring result corresponds to the sensing beam identifier or beam set identifier, and there is also a corresponding relationship between the sensing beam identifier or beam set identifier and the timer. According to the corresponding relationship between the sensing beam identifier or beam set identifier and the timer, the timing process of the corresponding timer is updated.

[0139] Optionally, the UE includes a list of timers corresponding to the sensing beam identifier or the beam set identifier, such as:

[0140] sensing beam1 / beam set1 corresponds to lbt-FailureDetectionTimer_a

[0141] sensing beam2 / beam set2 corresponds to lbt-FailureDetectionTimer_b

[0142] sensing beam3 / beam set3 corresponds to lbt-FailureDetectionTimer_c

[0143] Then, according to the channel monitoring result and the sensing beam identifier or beam set identifier corresponding to the channel monitoring result, the timer corresponding to the sensing beam identifier or beam set identifier is updated.

[0144] In some embodiments, when the channel monitoring result indicates that the channel monitoring has failed, the timer corresponding to the sensing beam identifier or the beam set identifier is restarted, that is, the timer starts again from 0 or from a specified starting time point.

[0145] Optionally, when the timer corresponding to the perception beam identifier or the beam set identifier reaches the timing threshold, the counter corresponding to the perception beam identifier or the beam set identifier is set to zero, indicating that the channel monitoring result corresponding to the current LBT channel monitoring does not fail within the timing threshold, that is, the channel quality monitored by LBT is better.

[0146] Optionally, the MAC layer receives an LBT failure instance indicated by the physical layer, and simultaneously receives a sensing beam / beam set identifier corresponding to the LBT failure instance;

[0147] Alternatively, the physical layer does not inform the sensing beam / beam set at the time of LBT failure, but informs the MAC layer when determining or updating the currently used sensing beam / beam set.

[0148] Optionally, determining whether the sensing beam or beam set changes may be performed by at least one of the following situations:

[0149] First, when the transmission beam of the listen-before-speak LBT is switched from the first beam to the second beam, and the perception beam or beam set corresponding to the first beam is different from the perception beam or beam set corresponding to the second beam, it is determined that the perception beam or beam set has changed.

[0150] That is, the UE's transmit beam is switched from beam 1 to beam 2, and the sensing beam or beam set corresponding to beam 2 is different from the sensing beam or beam set corresponding to beam 1.

[0151] Second, when the perception beam or beam set corresponding to the transmit beam of the listen-before-speak LBT is switched from the first perception beam or beam set to the second perception beam or beam set, it is determined that the perception beam identifier or beam set identifier changes.

[0152] That is, the UE's transmit beam remains unchanged, but the sensing beam or beam set corresponding to the transmit beam is switched to a new sensing beam or beam set.

[0153] To summarize, the embodiments of the present application synchronously determine the sensing beam or beam set corresponding to the LBT channel monitoring result during the LBT channel monitoring result, thereby determining whether the beam corresponding to the channel monitoring result has changed, avoiding the problem of low LBT accuracy caused by different beam corresponding counts or timings on the same counter / timer, and solving the counting / timing of directional LBT.
