Abstract
Description
Technical Field
[0001] This application relates to the field of wireless communication technology, and in particular to a method and apparatus for reporting transmission failures. Background Technology
[0002] In New Radio (NR) systems, when using high-frequency bands for transmission, beamforming technology can be employed to improve data transmission quality by utilizing physical channels and physical signals. Beamforming allows network-side equipment to concentrate transmit power in a specific direction (e.g., the direction of the UE), increasing the power of the received signal. However, when the link between the network-side equipment and the UE is blocked, the received power at the UE is significantly reduced, leading to a transmission (beamforming) failure event. NR defines a beam failure recovery mechanism, also called a transmission failure mechanism or link recovery mechanism. After detecting a transmission failure event, the UE reports it to the network-side equipment, which then replaces the serving beam for the UE, ensuring normal transmission.
[0003] In the Medium Access Control (MAC) layer, the transmission failure detection process for each Transmission Point (TRP) is performed independently. That is, each TRP (or BFD RS set) uses an independent timer and counter to detect beam failure events. Even if beam failure occurs at both Transmission Points (TRPs), the transmission periods of the Beam Failure Detection Reference Signals (BFD RS) for the two TRPs may differ, and the times at which the transmission failures occur may also differ. Consequently, the MAC layer may identify the failures of the two TRPs at different times. In this case, the MAC layer will trigger two transmission failure reports, resulting in a waste of system resources. Summary of the Invention

All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

The name of the terminal device may differ in different systems; for example, in a 5G system, the terminal device can be called User Equipment (UE).

Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names.

In some network structures, the network equipment may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and distributed unit may be geographically separated.
[0163] A beam failure recovery mechanism is defined in the New Radio (NR) system. After detecting a transmission failure event, the terminal reports it to the network-side equipment, which then replaces the serving beam for the terminal to ensure normal transmission. The method for Rel-15 / 16 terminals to detect transmission failures is as follows:
[0164] Terminal physical layer detection behavior: The terminal detects BFD RSs configured by the network-side equipment or determined by the terminal according to predefined rules. Each serving cell (including PCell, PSCell, or SCell) contains a BFD RS set (also called set q0), and each BFD RS set contains at most two BFD RSs. When all BFD RSs in a BFD RS set meet certain conditions (e.g., a difference from a predefined threshold, such as assuming BLER is higher than 10%), the terminal's physical layer indicates a failure event to the terminal's higher layers. The terminal's reporting period is the maximum value between the shortest period of the BFD RSs in the BFD RS set and 2ms. That is, if the shortest period among multiple BFD RSs is greater than 2ms, the failure indication is based on the shortest period value of the BFD RS; otherwise, the failure indication is based on 2ms. The physical layer failure indication for each serving cell is performed independently.
[0165] The terminal MAC layer determines the behavior for transmission failures as follows: Each serving cell corresponds to a beam failure indicator counter (BFR_COUNTER), initially set to 0; beam failure detection for each serving cell also corresponds to a timer (beamFailureDetectionTimer). The detection behavior is as follows:
[0166] 1> If a beam (transmission) failure indication has been received from the physical layer:
[0167] 2> Start or restart the beamFailureDetectionTimer;
[0168] 2>Increment the BFI_COUNTER counter value by 1;
[0169] 2> If BFI_COUNTER >= the maximum number of failures configured in the higher-layer signaling configuration (beamFailureInstanceMaxCount):
[0170] 3> If the serving cell is SCell:
[0171] 4> Trigger a BFR on this serving cell;
[0172] 3> Otherwise:
[0173] 4> Initiate a random access procedure on SpCell
[0174] 1> If the beamFailureDetectionTimer times out; or
[0175] 1> If the timer beamFailureDetectionTimer, the maximum number of failures parameter beamFailureInstanceMaxCount, or any reference signal related to this serving cell used in beam failure detection is reconfigured by higher-layer signaling:
[0176] 2> Clear the value of counter BFI_COUNTER (set it to 0).
[0177] Terminal MAC layer triggers beam failure recovery reporting behavior:
[0178] As described above:
[0179] For SpCell, if the counter reaches the maximum number of failures configured by the higher-layer signaling, a random access procedure is initiated.
[0180] For SCell, if the counter reaches the maximum number of failures configured by the higher-level signaling, a BFR is triggered.
[0181] The specific behavior that triggers BFR is:
[0182] 1> For a SCell, if the beam failure recovery procedure determines that at least one BFR was triggered and not canceled, and the candidate beam evaluation according to the requirements in TS38.133 has been completed (referring to the evaluation of whether there are beams above the threshold):
[0183] 2> If the UL-SCH resource is available for a new transmission and if this UL-SCH resource can accommodate the BFR MACCE plus its subheading as the result of an LCP:
[0184] 3> Instructions for reuse and assembly processes to generate BFR MAC CE.
[0185] 2> Or if the UL-SCH resource is available for a new transmission and if this UL-SCH resource can accommodate the trimmed BFR MAC CE plus its child header as a result of an LCP:
[0186] 3> Instructions for reuse and assembly processes to generate trimmed BFR MAC CE.
[0187] 2> or:
[0188] 3> For each SCell that has triggered the BFR process and has not been canceled, and for which candidate beam evaluation has been completed according to the requirements in TS38.133, a beam failure recovery trigger is initiated.
[0189] TRP-based transmission failure recovery:
[0190] In the MTRP BFR physical layer design, cell-level BFR and TRP-level BFR are defined. When a beam failure occurs in one TRP within a cell, a TRP-level BFR is considered to have occurred; when all TRPs (e.g., two) in a cell fail, a cell-level BFR is considered to have occurred. When a beam failure occurs in one TRP, the terminal reports it to the base station in a manner similar to that used when a Rel-16 SCell fails. When a cell-level beam failure occurs, the terminal's reporting behavior may differ from that at the TRP level. For example, it may use a RACH-based method to report cell-level BFR for SpCells (including PCCells and PSCells).
[0191] Under MTRP BFR, the process for determining transmission failure at the terminal MAC layer is similar to that in Rel-15 / 16. Each TRP introduces a beam failure indicator counter (BFR_COUNTER) and a timer (beamFailureDetectionTimer). The transmission failure determination process for each TRP is the same as that for each cell in Rel-15 and Rel-16, i.e., refer to the behavior of determining transmission failure at the terminal MAC layer mentioned above.
[0192] In the MAC layer processing, the transmission failure judgment process for each TRP is performed independently. That is, each TRP (or BFDRS set) uses an independent timer and counter to determine beam failure events. Even if two transmission points (TRPs) experience beam failure, the transmission periods of the BFDRS for the two TRPs may differ, and the time points at which the transmission failures occur may also differ. Consequently, the MAC layer may identify the failure times of the two TRPs differently. In this case, how the MAC layer determines the number of TRPs experiencing beam failure is unclear. This could lead the MAC layer to consistently report beam failures as if only one TRP is experiencing a beam failure, thus failing to support the reporting behavior when two TRPs in RAN1 experience beam failures.
[0193] This application addresses the problem that beam failure (also called transmission failure) judgments are performed independently by two or more BFD RS sets in a cell, and the times at which they are judged as transmission failures may be different. It proposes a method for multiple BFD RS sets to jointly perform transmission failure judgments, which is used to support the mechanism of joint transmission failure reporting of two BFD RS sets in RAN1, thereby avoiding the need to report independently for each BFD RS set, improving reporting efficiency and saving system resources.
[0194] In various embodiments of this application, the transmission failure described can also be a beam failure, a link failure, etc., and failure can also be an inability. Multiple descriptions and their meanings can be used interchangeably. TRP is Physical Transmission Point, which can be understood as physical resources, such as the index of BFD RS set, the subset index of Control Resource Set (CORESET), the CORESET-related higher-level parameter CORESETPoolIndex, the BFR process index, and the index of New Candidate Beam Indication Reference Signal (NBI RS set), etc. The embodiments of this application do not limit this.
[0195] Figure 1 This is a schematic diagram of the transmission failure reporting method provided in the embodiments of this application, as shown below. Figure 1 As shown, the method includes:
[0196] Step 100: Determine whether the first physical resource has experienced a transmission failure;
[0197] Specifically, the terminal device is configured with multiple physical resources for data transmission. For example, two physical resources can be configured simultaneously, such as a first physical resource and a second physical resource. The first physical resource and the second physical resource mentioned in this application are only distinguished by name for ease of description and are not intended to limit their order of use or manner. The terminal device can first determine whether the first physical resource is transmitting normally, that is, it can determine whether the first physical resource has failed to transmit. The method for determining transmission failure can adopt the existing method, and this application embodiment does not limit it.
[0198] The first and second physical resources mentioned in the embodiments of this application can be transmission resources corresponding to the BFD RS set index, CORESET subset index, CORESET related higher-level parameters CORESETPoolIndex, BFR process index, and New Candidate Beam Indication Reference Signal (NBI RS set) index, or corresponding BFD RS resources or BFD RS set resources, or corresponding CORESET resources, or corresponding PDCCH DMRS resources, or corresponding PDCCH resources, etc. The embodiments of this application do not impose limitations on these. The embodiments of this application can be described using BFD RS set as an example of physical resources.
[0199] Step 101: If it is determined that the first physical resource has failed to transmit, trigger a first transmission failure report or a second transmission failure report according to the transmission status of the second physical resource. The first transmission failure report includes transmission failure information corresponding to the first physical resource and the second physical resource, and the second transmission failure report includes transmission failure information corresponding to the first physical resource.
[0200] After the terminal device determines that the first physical resource has experienced a transmission failure, it can further trigger a failure report based on the transmission status of the second physical resource. The transmission status of the second physical resource can include successful transmission (i.e., normal transmission) and transmission failure. The failure reports triggered in this embodiment differ depending on the transmission status of the second physical resource. Specifically, when the second physical resource's transmission status is a transmission failure, the terminal device can trigger a first transmission failure report, which includes transmission failure information corresponding to both the first and second physical resources—that is, a joint report of information indicating that both physical resources have failed to transmit. Conversely, when the second physical resource's transmission status is a successful transmission, the terminal device can trigger a second transmission failure report, which includes transmission failure information corresponding to the first physical resource but does not include information indicating that the second physical resource has failed to transmit.
[0201] It is understood that the first transmission failure report can include not only transmission failure information of physical resources within the same cell, but also transmission failure information of physical resources in other cells. For example, the first physical resource and the second physical resource can be physical resources of the same cell, or they can be physical resources of different campuses.
[0202] The transmission failure reporting method provided in this application embodiment performs transmission failure judgment jointly for multiple BFD RS sets, which is used to support the mechanism of joint transmission failure reporting of two BFD RS sets in RAN1, thereby avoiding always reporting independently for each BFD RS set, improving reporting efficiency and saving system resources.
[0203] The transmission failure joint reporting mechanism provided in this application embodiment can be implemented in various ways, which will be described below.
[0204] Method 1 for achieving joint reporting:
[0205] After detecting a transmission failure in the first BFD RS set, the terminal device can wait for a period of time to determine the transmission failure event, and then trigger the transmission failure report corresponding to the transmission failure event. The transmission failure event includes at least one of the following:
[0206] The number of BFD RS sets that experienced transmission failures (in a cell);
[0207] (In a cell) one BFD RS set experienced a transmission failure;
[0208] (In a cell) Two or more BFD RS sets experience transmission failures.
[0209] Specifically, if a transmission failure is determined to have occurred to the first physical resource, triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource may include:
[0210] If a transmission failure is determined to have occurred to the first physical resource, within a first time period, a first transmission failure report or a second transmission failure report is triggered based on the transmission status of the second physical resource, specifically including:
[0211] After determining that the first physical resource has experienced a transmission failure, if it is determined that the second physical resource has also experienced a transmission failure within a first time period, then the first transmission failure report is triggered; or
[0212] If, after determining that the first physical resource has experienced a transmission failure, the second physical resource has not experienced a transmission failure within a first time period, then the second transmission failure report is triggered.
[0213] The above implementation method may further include, after determining that the first physical resource has experienced a transmission failure, if it is determined that the second physical resource has not experienced a transmission failure, then triggering the second transmission failure report.
[0214] In the above implementation method, when a transmission failure of the first BFD RS set is detected, a joint report can be made after the transmission status of the second BFD RS set is determined by waiting for a period of time.
[0215] Alternatively, there are several ways to implement the terminal device waiting for a period of time; two methods are described below.
[0216] One way to implement the waiting period is to use a timer to time the first time period.
[0217] The timer can be a newly introduced timer (e.g., a first timer), or a previously existing timer can be reused (e.g., the transmission failure indicator timer beamFailureInstanceMaxCount corresponding to the first BFD RS set can be used as a second timer). Depending on the timer selection, in the above method, triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource when a transmission failure is determined to have occurred in the first physical resource includes:
[0218] When it is determined that the first physical resource has experienced a transmission failure, a first timer is started to time the first time period; or
[0219] When it is determined that the first physical resource has failed to transmit, the transmission failure indicator timer corresponding to the first physical resource is reused as a second timer, and the second timer is started to count the first time period.
[0220] Specifically, "starting" refers to starting or restarting a timer. When a transmission failure is detected in the first BFD RS set, the first timer or the second timer is started or restarted. During the operation of the first timer or the second timer, or after the timeout, a transmission failure event is determined and reported. Before the first timer or the second timer expires, if the counters corresponding to two or more BFD RS sets reach their maximum values, a report of a transmission failure event corresponding to two or more BFD RS sets is initiated; if the counter corresponding to only one BFD RS set reaches its maximum value, a report of a transmission failure event corresponding to that BFD RS set is initiated.
[0221] Optionally, the method further includes:
[0222] If, during or after the first or second timer expires, it is determined that the second physical resource also experienced a transmission failure, then the first transmission failure report is triggered; or,
[0223] If, during the timing of the first or second timer or after its timeout, it is determined that the second physical resource has not experienced a transmission failure, then a second transmission failure report is triggered; or,
[0224] If the transmission failure indicator counters corresponding to the first physical resource and the second physical resource reach their maximum values, the first transmission failure report is triggered; or,
[0225] When the transmission failure indicator counter corresponding to the second physical resource reaches its maximum value, the second transmission failure report is triggered.
[0226] For example, a timer (e.g., a first timer) is introduced to determine transmission failure events. Specifically, when the MAC layer of the terminal device determines that a BFD RS set (e.g., the first BFD RS) has failed to transmit, it starts or restarts the first timer. Before the first timer expires, if another BFD RS set in the same cell as the first BFD RS set also fails to transmit (i.e., BFI_COUNTER >= the maximum number of failures configured by the higher-layer signaling, beamFailureInstanceMaxCount), then it can be considered that both BFD RS sets have failed to transmit. In other words, the transmission failure event at this time is that both BFD RS sets in the cell have failed to transmit, thus triggering the reporting method corresponding to the transmission failure of both BFD RS sets. If the first timer expires and only one BFD RS set still fails to transmit, then it can be considered that only one BFD RS set has failed to transmit. In other words, the transmission failure event at this time is that one BFD RS set in the cell has failed to transmit, thus triggering the reporting method corresponding to the transmission failure of one BFD RS set.
[0227] In this embodiment, the two BFD RS sets independently perform transmission failure detection, but when determining the reporting method, the two BFD RS sets (i.e., TRPs) need to make a joint judgment. Specifically, when the BFI_COUNTER corresponding to one BFD RS set (e.g., the first BFD RS set) reaches its maximum count, if the BFI_COUNTER corresponding to another BFD RS set (e.g., the second BFD RS set) in the serving cell has not reached its maximum count, then the first timer corresponding to the first BFD RS set is started or restarted, and the value of the BFI_COUNTER corresponding to that BFD RS set remains unchanged.
[0228] Optionally, if it is determined that the first physical resource has failed to transmit, and it is also determined that the second physical resource has failed to transmit, then the first transmission failure report is triggered, including: if it is determined that the first physical resource has failed to transmit and the second physical resource has also failed to transmit, then the first transmission failure report is triggered.
[0229] That is, when the first BFD RS set is judged to have failed to transmit, the BFI_COUNTER corresponding to another BFD RS set (the second BFD RS set) in the serving cell also reaches its maximum count (for example, the second BFD RS set's BFI_COUNTER may reach its maximum count and then wait for a period of time, i.e., when the second BFD RS set is judged to have failed to transmit, the first BFD RS set has not yet been judged to have failed to transmit, in which case the first timer is started for the second BFD RS set to wait for the transmission status judgment of the first BFD RS set, i.e., the second BFD RS set has failed for a period of time, at which point it is equivalent to each BFD RS set introducing a first timer; or the BFI_COUNTER corresponding to the second BFD RS set and the BFI_COUNTER corresponding to the first BFD RS set may both reach their maximum count at the same time), then there is no need to start or restart the first timer corresponding to the first BFD RS set, and the reporting type is directly determined according to the type of the serving cell.
[0230] When the first timer runs (for example, it could be the first timer corresponding to any one of the BFD RS sets, not necessarily the first timer corresponding to the first BFD RS set), if the BFI_COUNTER corresponding to both BFD RS sets reaches its maximum count, the reporting type is determined based on the type of the serving cell. For example, if the serving cell is an SCell, a BFR corresponding to the transmission failure of two BFD RS sets is triggered on this serving cell; if the serving cell is an SpCell, a random access procedure corresponding to the transmission failure of two BFD RS sets is initiated on the SpCell, or a BFR corresponding to the transmission failure of two BFD RS sets is triggered. After triggering the corresponding report, the BFI_COUNTER corresponding to both BFD RS sets is cleared to zero. The BFR or random access procedure corresponding to the transmission failure of two BFD RS sets can also be a cell-level transmission failure report. The random access procedure can be contention-based random access or non-contention-based random access; this application embodiment does not impose any restrictions on this.
[0231] When the first timer corresponding to the first BFD RS set times out, or when the first timer corresponding to any BFD RS set (first or second BFD RS set) times out, and only one BFD RS set's BFI_COUNTER reaches its maximum count, the existing protocol mechanism can be reused. That is, if the serving cell is a SCell, a BFR is triggered on that serving cell; otherwise, a random access procedure is initiated on the SpCell. Besides introducing a new first timer, existing timers can also be reused. For example, when the BFI_COUNTER corresponding to a failed BFD RS set (e.g., the first BFD RS set) reaches its maximum count, and the beamFailureDetectionTimer has not yet timed out, the TRP corresponding to the first BFD RS set is considered to have failed. While waiting for the second BFD RS set to determine if it has failed, the beamFailureDetectionTimer has no practical effect. At this time, the beamFailureDetectionTimer can be restarted; for simplicity, this timer can also be called the second timer. Before the second timer expires, if another BFD RS set is also determined to have experienced a transmission failure, then reports corresponding to the transmission failures of both TRPs (BFD RS sets) are triggered; otherwise, a report corresponding to the transmission failure of one BFD RS set is triggered. In this case, the timer functions corresponding to the two BFD RS sets may be different. For example, for the BFD RS set that experienced a transmission failure first (e.g., the first BFD RS set), the second timer is used to determine the specific transmission failure event that occurred, i.e., whether one or both BFD RS sets experienced transmission failures. For the BFD RS set that experienced a transmission failure later, or that did not experience a transmission failure (e.g., the second BFD RS set), the second timer, also known as the beamFailureDetectionTimer, is used to determine whether the second BFD RS set experienced a transmission failure event.
[0232] For the first BFD RS set that experiences a transmission failure, the function of the second timer differs before and after the failure is determined. Before the failure, the second timer is used to determine whether the BFD RS set has experienced a transmission failure event. After the failure, the second timer is used to determine the specific transmission failure event that occurred—whether one or two BFD RS sets failed. The timer value can also differ between these two time periods. For example, the network-side device can configure the second timer's duration to be Ams and Bms respectively for the two time periods, or configure the second timer's duration to be Ams and Bms respectively for the two purposes (determining whether one BFD RS set has experienced a transmission failure event, and determining whether another BFD RS set has experienced a transmission failure event after one BFD RS set has failed).
[0233] Taking the first BFD RS set as an example, the detection behavior of the terminal device is as follows:
[0234] 1> If a beam (transmission) failure indication has been received from the physical layer:
[0235] 2> Start or restart the beamFailureDetectionTimer;
[0236] 2>Increment the value of the BFI_COUNTER1 counter by 1;
[0237] 2> If BFI_COUNTER1>== the maximum number of failures configured in the higher-layer signaling configuration (beamFailureInstanceMaxCount1):
[0238] 3> If BFI_COUNTER2>== the maximum number of failures configured in the higher-layer signaling configuration (beamFailureInstanceMaxCount2):
[0239] 4> If the serving cell is SCell:
[0240] 5> Trigger the first transmission failure report (BFR) on this serving cell;
[0241] 4> Otherwise:
[0242] 5> Initiate the corresponding random access procedure on SpCell to report the first transmission failure;
[0243] 3> If BFI_COUNTER2 < beamFailureInstanceMaxCount2 (the maximum number of failures configured by the higher-layer signaling):
[0244] 4> Start or restart the first or second timer.
[0245] 4> If BFI_COUNTER2>== the maximum number of failures configured in the higher-layer signaling configuration (beamFailureInstanceMaxCount2):
[0246] 5> If the serving cell is SCell:
[0247] 6> Trigger the first transmission failure report (BFR) on this serving cell;
[0248] 5> Otherwise:
[0249] 6> Initiate the corresponding random access procedure on SpCell to report the first transmission failure;
[0250] 4> If the first or second timer times out or fails, or if BFI_COUNTER2 < beamFailureInstanceMaxCount2 (the maximum number of failures configured by the higher-layer signaling):
[0251] 5> Trigger the corresponding BFR (Breakthrough Rate Failure) for the second transmission failure on this serving cell;
[0252] 1> If timer beamFailureDetectionTimer1 times out or fails; or
[0253] 1> If the timer beamFailureDetectionTimer1, the maximum number of failures parameter beamFailureInstanceMaxCount1, or any reference signal related to this serving cell used in transmission failure detection is reconfigured by higher-layer signaling:
[0254] 2> Clear the value of counter BFI_COUNTER1 (set it to 0).
[0255] BFI_COUNTER1 and BFI_COUNTER2 above represent the counters corresponding to the first BFD RS set and the second BFD RS set, respectively. beamFailureDetectionTimer1 and beamFailureDetectionTimer2 represent the timers corresponding to the first BFD RS set and the second BFD RS set, respectively. The first timer or the second timer represents the timer corresponding to the first BFD RS set.
[0256] The second implementation method is to wait for a period of time and then determine the transmission status of the second physical resource at or before a fixed time point.
[0257] Accordingly, the step of triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource within a first time period, when it is determined that a transmission failure has occurred in the first physical resource, includes:
[0258] After determining that the first physical resource has experienced a transmission failure, at a first time point, or at a time point before the first time point, if it is determined that the second physical resource has also experienced a transmission failure, then the first transmission failure report is triggered; or
[0259] If, after determining that the first physical resource has failed to transmit, at a first time point or at a time point before the first time point after determining that the first physical resource has failed to transmit, it is determined that the second physical resource has not failed to transmit, then the second transmission failure report is triggered.
[0260] It is understandable that the time point at which the transmission of the first physical resource fails can be the start time point of a time period, and the first time point can be the end time point of that time period. A time point before the first time point can be any time point within that time period.
[0261] Specifically, instead of using the timer mechanism described above to determine transmission failure events, a fixed point in time (e.g., the first time point) is used. That is, after determining that a BFD RS set has experienced a transmission failure, a report corresponding to that BFD RS set's transmission failure is not immediately triggered. Instead, the process waits for Xms before determining the transmission failure event, or it is determined at the first time point. For example, if the number of BFD RS sets experiencing transmission failures at the first time point is 1, then a report corresponding to that BFD RS set's transmission failure is triggered. If the number of BFD RS sets experiencing transmission failures at the first time point is 2, and the two BFD RS sets belong to the same cell, then reports corresponding to the transmission failures of both BFD RS sets are triggered, i.e., a cell-level transmission failure report is triggered. If the number of BFD RS sets experiencing transmission failures at the first time point is 2, but the two BFD RS sets do not belong to the same cell, then a report corresponding to the transmission failure of a single BFD RS set in multiple cells is triggered, for example, still a TRP-level transmission failure report.
[0262] For example, if the number of BFD RS sets with transmission failures in a cell (e.g., SpCell or SCell) reaches 2 before the first time point arrives, or before the first or second timer expires, a cell-level transmission failure report is triggered. If the number of BFD RS sets with transmission failures in a cell (e.g., SpCell or SCell) does not exceed 2 before the first time point arrives, or before the first or second timer expires, the terminal device continues to wait until the first time point to determine the transmission failure event and report it accordingly. Alternatively, if the number of BFD RS sets with transmission failures in a certain SCell reaches 2 before the first time point arrives, or before the first or second timer expires, but the number of BFD RS sets with transmission failures in the SpCell does not exceed 2, the terminal device continues to wait until the first time point to determine the transmission failure event and report it accordingly.
[0263] The first time point can be:
[0264] Determine the time point at which the transmission of the first physical resource failed; or
[0265] Determine the time point after a preset duration has elapsed following the transmission failure of the first physical resource; or
[0266] Determine the time point at which the first cell-level transmission failure event is triggered or reported after the first physical resource transmission failure occurs; or
[0267] Determine the time point at which the first transmission failure is triggered or reported after the first physical resource experiences a transmission failure; or
[0268] The time point determined from two candidate time points according to the nearest, farthest, maximum, or minimum value, wherein the two candidate time points include a first fixed time point and the time point at which the first cell-level transmission failure event is triggered or reported after determining that the first physical resource has experienced a transmission failure; or
[0269] The time point determined from two candidate time points according to the nearest, farthest, maximum, or minimum value, wherein the two candidate time points include a second fixed time point and the time point at which the first transmission failure is triggered or reported after the first physical resource transmission failure occurs; or
[0270] The time point corresponding to the timeout of the timer (including the first timer or the second timer).
[0271] Specifically, when a transmission failure is detected in the first BFD RS set, the transmission failure event is judged and reported before the first time point. If the counters corresponding to two or more BFD RS sets reach their maximum values, the transmission failure event corresponding to two or more BFD RS sets is reported. If the counter corresponding to only one BFD RS set reaches its maximum value, the transmission failure event corresponding to that BFD RS set is reported.
[0272] Optionally, the first time point can be the time point at which the first cell-level transmission failure event is triggered or reported after a BFD RS set is determined to have failed transmission. For example, SpCell is configured with two BFD RS sets, i.e., performing TRP-level transmission failure reporting, while SCell 1 and SCell 2 are each configured with only one BFD RS set, i.e., performing cell-level transmission failure reporting. When one BFD RS set of SpCell is determined to have failed transmission, the corresponding transmission failure report is not triggered immediately. Instead, the transmission failure event of the second BFD RS set is assessed. If SCell 1 or SCell 2 experiences a transmission failure, at the time point when SCell 1 or SCell 2 triggers or performs cell-level transmission failure reporting, the transmission failure event of SpCell (one or both BFD RS sets have failed transmission) is assessed and reported.
[0273] Alternatively, if SCell 1 or SCell 2 is configured with two BFD RS sets and both BFD RS sets fail to transmit, i.e., a cell-level transmission failure report is triggered, the transmission failure event of SpCell (one or two BFD RS sets fail to transmit) is determined and reported at the time when SCell 1 or SCell 2 triggers or performs a cell-level transmission failure report.
[0274] Alternatively, SpCell can be configured for TRP-level transmission failure recovery, and SCell 1 and SCell 2 can be configured for cell-level transmission failure recovery. When a BFD RS set in SpCell fails to transmit, the terminal device does not trigger a corresponding transmission failure report but waits for a period of time. If other cells (such as SCell 1 or SCell 2) trigger a cell-level beam failure report, then the terminal device will report the transmission failure along with the other cells. That is, the index of the failed cell and / or the corresponding BFD RS set index is carried in the BFR MAC CE, or the first or third step of the random access procedure carries or bears the index of the failed cell and / or the corresponding BFD RS set index.
[0275] The first time point can also be the time point at which a transmission failure is triggered or reported after a BFD RS set is determined to have failed. For example, each cell can be independently configured to either report transmission failures at the cell level or report two BFD RS set transmission failure events. If a cell supports reporting two BFD RS set transmission failures, while one or more other cells only support reporting a single BFD RS set transmission failure, for a cell that supports two BFD RS set transmission failures, when a BFD RS set fails, the terminal device can wait for a period of time before triggering a transmission failure. If other cells or TRPs (corresponding to BFD RS sets) report transmission failure events, such as cell-level or TRP-level transmission failure reports, the terminal device can also stop waiting and report the transmission failure event along with other cells. That is, any type of transmission reporting is acceptable, and this embodiment does not impose any restrictions on this.
[0276] The time point at which the first cell-level transmission failure event is triggered or reported, or the time point at which the first transmission failure is triggered or reported, can be the time point at which any cell's transmission failure report or any transmission failure report (corresponding to any BFD RS set) sends an LRR on the PUCCH-SR resource, the time point at which a BFR MAC CE is sent on an available PUSCH resource, the time point at which a preamble is sent, the time point at which a BFR MAC CE is carried in msg3 or msgAPUSCH, the time point at which a cell-level transmission failure is determined or triggered, or the time point at which other cells or TRP (BFD RS set) determine or trigger a transmission failure, etc.
[0277] In addition to the single time point mentioned above, the first time point can also be the closest (shortest, smallest) or furthest (longest, largest) of two or more time points. For example, the first time point can be the closest of a first fixed time point (the time point Xms after a BFD RS set is judged to have failed transmission) and the time point when the first cell-level transmission failure event is triggered or reported after a BFD RS set is judged to have failed transmission, or the furthest of a second fixed time point (the time point Yms after a BFD RS set is judged to have failed transmission) and the time point when the first transmission failure event is triggered or reported after a BFD RS set is judged to have failed transmission, etc. Then the terminal device reports the transmission failure according to the time point determined by the closest, furthest, largest, or smallest value, that is, it waits until the determined time point and reports the transmission failure according to the transmission failure event at the determined time point (the first time point).
[0278] The first time point can also be the time point at which the transmission of the first BFD RS set fails; it can also be the time point at which a preset duration has elapsed after the transmission of the first BFD RS set fails, such as Ams (where A is a value greater than or equal to 0) after the first BFD RS set is determined to have failed transmission; or it can be the time point corresponding to the timeout of the first timer or the second timer.
[0279] Furthermore, in the embodiments of this application, when determining a transmission failure event of SpCell, the first BFD RS set that experiences transmission failure refers to one BFD RS set of SpCell. That is, when one BFD RS set of SpCell experiences transmission failure, the terminal device adopts a waiting mechanism, waiting for a period of time, or at another point in time to determine whether both BFD RS sets of SpCell have experienced transmission failure. Similarly, when determining a transmission failure event of SCell, the first BFD RS set that experiences transmission failure refers to one BFD RS set of SCell. That is, when one BFD RS set of SCell experiences transmission failure, the terminal device adopts a waiting mechanism, waiting for a period of time, or at another point in time to determine whether both BFD RS sets of SCell have experienced transmission failure.
[0280] Method 2 for achieving joint reporting:
[0281] After detecting a failure in the first BFD RS set, the terminal device determines, based on a first condition, whether to wait for a period of time before confirming the transmission failure event, and then triggers the corresponding transmission failure report. The transmission failure event includes at least one of the following:
[0282] The number of BFD RS sets that experienced transmission failures (in a cell);
[0283] (In a cell) one BFD RS set experienced a transmission failure;
[0284] (In a cell) Two or more BFD RS sets experience transmission failures.
[0285] Specifically, upon determining that a transmission failure has occurred in the first physical resource, a first transmission failure report or a second transmission failure report is triggered based on the transmission status of the second physical resource, including:
[0286] After determining that the first physical resource has failed to transmit, a first transmission failure report or a second transmission failure report is triggered based on a first condition and the transmission status of the second physical resource within a first time period.
[0287] If the first condition is met, a first transmission failure report or a second transmission failure report is triggered based on the transmission status of the second physical resource within the first time period. If it is determined that the second physical resource also experienced a transmission failure, the first transmission failure report is triggered; or, if it is determined that the second physical resource did not experience a transmission failure within the first time period, the second transmission failure report is triggered.
[0288] If the first condition is not met, then if the second physical resource also fails to transmit after the first physical resource fails to transmit, the first transmission failure report is triggered; or, if the second physical resource does not fail to transmit after the first physical resource fails to transmit, the second transmission failure report is triggered.
[0289] Compared to Method 1, the second method for joint reporting provided in this embodiment adds a judgment condition. Specifically, after detecting a transmission failure in the first BFD RS set, it determines whether to start or restart the first timer or the second timer based on a first condition. While the first or second timer is running or has timed out, it judges the transmission failure event and reports it. Alternatively, when a transmission failure in the first BFD RS set is detected, it determines the transmission failure event at a first time point based on the first condition and reports it.
[0290] The determination that the first condition is met includes any one of the following:
[0291] The transmission failure indication counter corresponding to the second physical resource is greater than 0, or greater than a certain value (this value can be a value configured by the network-side device, or a predefined value, such as 1 / 2, 1 / 3, etc. of the maximum number of times).
[0292] The transmission failure indication counter corresponding to the second physical resource is greater than a fixed value; the fixed value is configured on the network side or predefined.
[0293] The transmission quality parameters are worse than the threshold.
[0294] Receiving configuration or instructions from the network side can specifically mean that the terminal device receives configuration from the network side device, notifying the terminal device to start or restart the first timer or the second timer for the cell, or all cells corresponding to the terminal device, or at least one BFDRS set of the terminal device, or determining a transmission failure event at a first time point.
[0295] In this embodiment of the method, when the BFI_COUNTER corresponding to a BFD RS set (such as the first BFD RS set) is detected to have reached its maximum count, it can also be determined whether to start or restart the first timer based on a first condition, that is, whether to wait for a period of time. The first condition may be whether the BFI_COUNTER corresponding to another BFD RS set (the second BFD RS set) (in the same cell) is greater than 0 (that is, the MAC layer has received at least one failure indication during the running time of the timer beamFailureDetectionTimer corresponding to the second BFD RS set), or whether it is greater than a certain value (this value may be a value configured by the network-side device, or it may be a predefined value, such as 1 / 2, 1 / 3, etc. of the maximum count). For example, if the BFI_COUNTER value corresponding to the second BFD RS set is 0, or less than a certain value, the first timer will not be restarted or started. Instead, a report corresponding to the transmission failure of the first BFD RS set will be triggered directly, because the probability of the second BFD RS set also failing is very small. Otherwise, if the BFI_COUNTER value corresponding to the second BFD RS set is not 0, or is greater than or equal to a certain value, then a period of time will be waited before starting or restarting the first timer to see if the second BFD RS set will also fail. The decision to start or restart the first timer can also be based on other transmission quality-related conditions. For example, the physical layer can instruct the MAC layer, based on link quality, such as the BLER and SINR values of the assumed PDCCH of the second BFD RS set, to restart or start the first timer. The first condition can also be the configuration or indication of the network-side device. For example, if the terminal receives a configuration or indication from the network-side device, it may be notified to wait for a period of time after the first BFD RS set fails, or to wait for a period of time after any BFD RS set fails, to determine whether both BFD RS sets in a cell have failed.
[0296] In this method embodiment, the implementation of waiting for a period of time can also include the two methods mentioned above, namely, timing the first time period based on a timer or determining the transmission status of the second physical resource at or before a fixed time point.
[0297] Specifically, the step of triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource when a transmission failure of the first physical resource is determined to have occurred may include:
[0298] When it is determined that the first physical resource has experienced a transmission failure, a first timer is started to time the first time period; or
[0299] When it is determined that the first physical resource has failed to transmit, the transmission failure indicator timer corresponding to the first physical resource is reused as a second timer, and the second timer is started to count the first time period.
[0300] Optionally, the method further includes:
[0301] If, during or after the first or second timer expires, it is determined that the second physical resource also experienced a transmission failure, then the first transmission failure report is triggered; or,
[0302] If, during the timing of the first or second timer or after its timeout, it is determined that the second physical resource has not experienced a transmission failure, then a second transmission failure report is triggered; or,
[0303] If the transmission failure indicator counters corresponding to the first physical resource and the second physical resource reach their maximum values, the first transmission failure report is triggered; or,
[0304] When the transmission failure indicator counter corresponding to the second physical resource reaches its maximum value, the second transmission failure report is triggered.
[0305] Similar to the first timer, when a BFD RS set fails to transmit and the corresponding BFI_COUNTER reaches its maximum count, the first condition can be used to determine whether to start or restart the second timer, i.e. whether to wait for a period of time to determine whether another BFD RS set has also failed to transmit.
[0306] Alternatively, in the method, the step of triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource, upon determining that a transmission failure has occurred in the first physical resource, includes:
[0307] The transmission status of the second physical resource is determined at or before the first time point.
[0308] That is, after determining that the first physical resource has experienced a transmission failure, if it is determined that the second physical resource has also experienced a transmission failure at a first time point or at a time point before the first time point after determining that the first physical resource has experienced a transmission failure, then the first transmission failure report is triggered; or
[0309] If, after determining that the first physical resource has failed to transmit, at a first time point or at a time point before the first time point after determining that the first physical resource has failed to transmit, it is determined that the second physical resource has not failed to transmit, then the second transmission failure report is triggered.
[0310] For details regarding the two implementation methods for waiting for a period of time, as well as the methods for introducing a new first timer, reusing an existing timer as a second timer, and determining the first time point, please refer to the descriptions in the above embodiments, which will not be repeated here.
[0311] Method 3 for achieving joint reporting:
[0312] After the terminal device detects a failure in the first BFD RS set, it triggers a transmission failure report corresponding to the first BFD RS set, and then triggers either a first transmission failure report or a second transmission failure report based on the transmission status of the second BFD RS set.
[0313] Specifically, the step of triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource, when it is determined that a transmission failure has occurred in the first physical resource, includes:
[0314] After determining that the first physical resource has failed to transmit, a third transmission failure report is triggered, which includes the transmission failure information corresponding to the first physical resource.
[0315] Based on the transmission status of the second physical resource, trigger either the first transmission failure report or the second transmission failure report.
[0316] In Method 3, unlike Methods 1 and 2, after detecting a failure in the first BFD RS set, instead of waiting for a period of time to determine the transmission status of the second BFD RS set, a transmission failure report corresponding to the first BFD RS set is triggered first. For distinction, this triggered report is called the third transmission failure report. It is understood that both the third and second transmission failure reports include transmission failure information corresponding to the first physical resource, but their reporting times differ, and the content they include may also differ. For example, the third transmission failure report may be triggered the moment the first BFD RS set is determined to have failed, and the third transmission failure report may only contain the transmission failure event of the first BFD RS set. The second transmission failure report may be transmitted at a time after the first BFDRS set is judged to have failed. At this time, other cells or a certain TRP (BFD RS set) of another cell may also fail. Therefore, the second transmission failure report will carry the transmission failure event of the first BFD RS set, as well as the transmission failure event of a certain TRP (BFD RS set) of another cell. Thus, the transmission failure events carried by the third transmission failure report and the second transmission failure report may be different.
[0317] Further, triggering the first transmission failure report or the second transmission failure report based on the transmission status of the second physical resource includes:
[0318] After determining that the first physical resource has experienced a transmission failure, within the second time period, based on the transmission status of the second physical resource, either the first transmission failure report or the second transmission failure report is triggered; or
[0319] After triggering the third transmission failure report, if it is determined that the second physical resource has not experienced a transmission failure, then trigger the second transmission failure report, or
[0320] After triggering the third transmission failure report, if it is determined that the second physical resource has not experienced a transmission failure, then no other transmission failure reports will be triggered, and only the third transmission failure report will be retained.
[0321] Specifically, after detecting a failure in the first BFD RS set, the terminal device triggers a transmission failure report corresponding to the first BFD RS set, and within a second time period, triggers either a first transmission failure report or a second transmission failure report based on the transmission status of the second BFD RS set, including:
[0322] If, after determining that the first physical resource has experienced a transmission failure, the second physical resource also experiences a transmission failure within the second time period, then the first transmission failure report is triggered; or
[0323] If, after determining that the first physical resource has experienced a transmission failure, the second physical resource has not experienced a transmission failure within the second time period, then the second transmission failure reporting is triggered, or the triggering of the second transmission failure reporting is suspended.
[0324] Optionally, the implementation method for the terminal device to wait for a period of time (i.e., the second time period) can be the same as the two implementation methods described in the above method embodiments, including:
[0325] One way to implement the waiting period is to use a timer to time the first time period.
[0326] Specifically, after determining that the first physical resource has experienced a transmission failure, a first timer is started to time the second time period; or
[0327] After determining that the first physical resource has failed to transmit, the transmission failure indicator timer corresponding to the first physical resource is reused as a second timer, and the second timer is started to count the second time period.
[0328] The second implementation method is to wait for a period of time and then determine the transmission status of the second physical resource at or before a fixed time point.
[0329] Optionally, the method further includes:
[0330] If, during or after the first or second timer expires, it is determined that the second physical resource also experienced a transmission failure, then the first transmission failure report is triggered; or,
[0331] If, during the timing of the first or second timer or after its timeout, it is determined that the second physical resource has not experienced a transmission failure, then a second transmission failure report is triggered; or,
[0332] If the transmission failure indicator counters corresponding to the first physical resource and the second physical resource reach their maximum values, the first transmission failure report is triggered; or,
[0333] When the transmission failure indicator counter corresponding to the second physical resource reaches its maximum value, the second transmission failure report is triggered.
[0334] Specifically, after determining that a transmission failure has occurred in the first physical resource, triggering a first transmission failure report or a second transmission failure report within a second time period based on the transmission status of the second physical resource includes:
[0335] After determining that the first physical resource has experienced a transmission failure, at a second time point, or at a time point before the second time point after determining that the first physical resource has experienced a transmission failure, if it is determined that the second physical resource has also experienced a transmission failure, then the first transmission failure report is triggered; or
[0336] If, at a second time point or at a time point before the second time point after determining that the first physical resource has failed to transmit, the transmission failure of the second physical resource has not been determined, then the transmission failure of the second physical resource is triggered or the triggering of the transmission failure of the second physical resource is suspended.
[0337] It is understandable that the time point at which the transmission of the first physical resource fails can be the start time point of the second time period, and the second time point can be the end time point of that time period. A time point preceding the second time point can be any time point within that second time period.
[0338] For example, if the terminal device detects that the first BFD RS set has failed, it will trigger a transmission failure report corresponding to the first BFD RS set. If it is determined that the second BFD RS set has failed at or before the second time point, it will trigger transmission failure reports corresponding to both BFD RS sets.
[0339] For details regarding the two implementation methods for waiting for a period of time, as well as the introduction of a new first timer or the reuse of an existing timer as a second timer, please refer to the descriptions in the above embodiments, which will not be repeated here.
[0340] In this embodiment of the method, if the terminal device triggers a transmission failure report corresponding to two BFD RS sets at the second time point, the subsequent processing method for the previously triggered third transmission failure report includes at least one of the following:
[0341] Cancel the third transmission failure report; or
[0342] Continue sending the third transmission failure report, that is, continue sending the transmission failure report corresponding to the first BFD RS set that was triggered earlier; or
[0343] The third transmission failure report can be retained, suspended, or delayed. For example, if no response is received from the gNB for the transmission failure reports corresponding to the two BFD RSsets within a certain period of time, the terminal device can continue to send the transmission failure reports corresponding to the two BFD RSsets respectively, so that the previously multiplexed and assembled BFR MAC CE can continue to be used.
[0344] Alternatively, the second time point can be:
[0345] Determine the time point at which the transmission of the first physical resource failed; or
[0346] Determine the time point after a preset duration has elapsed following the transmission failure of the first physical resource; or
[0347] Determine the time point at which the first cell-level transmission failure event is triggered or reported after the first physical resource transmission failure occurs; or
[0348] Determine the time point at which the first transmission failure is triggered or reported after the first physical resource experiences a transmission failure; or
[0349] The time point determined from two candidate time points according to the nearest, farthest, maximum, or minimum value, wherein the two candidate time points include a first fixed time point and the time point at which the first cell-level transmission failure event is triggered or reported after determining that the first physical resource has experienced a transmission failure; or
[0350] The time point determined from two candidate time points according to the nearest, farthest, maximum, or minimum value, wherein the two candidate time points include a second fixed time point and the time point at which the first transmission failure is triggered or reported after the first physical resource transmission failure occurs; or
[0351] The time point corresponding to the timeout of the timer (including the first timer or the second timer).
[0352] The method for determining the second time point described in this embodiment can be the same as the method for determining the first time point described above. Please refer to the above embodiment for details, which will not be repeated here.
[0353] In this embodiment of the method, after detecting a transmission failure of a BFD RS set (e.g., the first BFD RS set), the terminal device can trigger a transmission failure report corresponding to that BFD RS set. For example, after a BFD RS set in an SCell or SpCell experiences a transmission failure, a BFR is triggered, containing the index of the BFD RS set that failed and the cell index, indicating that the corresponding BFD RS set in that cell has experienced a transmission failure. As another example, when a BFD RS set in an SpCell experiences a transmission failure, if there are no available PUSCH resources, or no corresponding SR resources are configured for sending LRR, or other conditions are met, a random access procedure (based on CFRA or CBRA) can be initiated to report the transmission failure event. Regardless of the reporting method used, the triggering begins when a BFD RS set transmission failure is detected at the MAC layer, which is the same as in the prior art. However, if the terminal device determines before a fixed time point (e.g., a second time point) that another BFD RS set (e.g., the second BFD RS set) in its cell has also experienced a transmission failure, it can send reports corresponding to the transmission failures of both BFD RS sets.
[0354] The second time point can be the same as the first time point. Alternatively, it can be a time point related to the transmission failure report triggered by the first BFD RS set. For example, the time point when the LRR corresponding to the first BFD RS set is sent on the SR resource could be the time point when the BFR MAC CE corresponding to the first BFD RS set is sent on the available PUSCH resource, the time point when the preamble corresponding to the first BFD RS set is sent, or the time point when the BFR MAC CE corresponding to the first BFD RS set is carried in msg3 or msgA, etc. For example, if the terminal device detects that the second BFD RS set in the same cell also failed to transmit before the transmission failure report corresponding to the first BFD RS set is sent, the terminal device can trigger transmission failure reports corresponding to the two BFD RS set transmission failure events.
[0355] If the terminal device triggers transmission failure reports corresponding to two BFD RS sets at the second time point, at least one of the following processing methods can be used for the transmission failure report triggered by the first BFD RS set:
[0356] Cancel the transmission failure report corresponding to the first BFD RS set.
[0357] Continue sending the transmission failure report corresponding to the first BFD RS set that was triggered earlier, that is, send two transmission failure reports for the transmission failure event of the first BFD RS set.
[0358] The terminal can retain, suspend, or delay the transmission failure report corresponding to the first BFD RS set. For example, if no response is received from the gNB for the transmission failure reports corresponding to the two BFD RS sets within a certain period of time, the terminal can continue to send the transmission failure reports corresponding to the two BFD RS sets respectively, so that the previously multiplexed and assembled BFR MAC CE can continue to be used.
[0359] If the terminal device determines at the second time point that only one BFD RS set has failed to transmit, it can continue to report the transmission failure corresponding to the first BFD RS set.
[0360] Similarly, the second time point can also be the time point at which the first timer or the second timer in the above embodiments expires.
[0361] Alternatively, the second time point could be the time when the first BFD RS set is determined to have failed in transmission, or the time when the first BFD RS set triggers a transmission failure report. Furthermore, after detecting a transmission failure in the first BFD RS set or triggering a transmission failure report corresponding to the first BFD RS set, the terminal device may not need to determine the transmission status of the second BFD RS set. Instead, it can directly initiate transmission failure reports for both BFD RS sets, or use the transmission failure report of the first BFD RS set to carry information indicating that both BFD RS sets have failed in transmission, even if the second BFD RS set has not yet been determined to have failed in transmission.
[0362] Method 4 for achieving joint reporting:
[0363] After detecting a transmission failure in the first BFD RS set, the terminal device determines the transmission failure event or the triggered transmission failure reporting based on a second condition. If the second condition is met, the terminal device uses at least one of the following reporting methods:
[0364] The terminal device initiates transmission failure reports for two BFD RS sets;
[0365] The terminal device reports a failure in the transmission of the first BFD RS set, carrying information that both BFD RS sets have failed to transmit.
[0366] The terminal device initiates transmission failure reports for two BFD RS sets at the second time point;
[0367] The terminal device initiates a transmission failure report for the first BFD RS set at the second time point, and carries information that both BFD RS sets have failed to transmit.
[0368] Specifically: If a transmission failure is determined to have occurred to the first physical resource, based on the transmission status of the second physical resource, a first transmission failure report or a second transmission failure report is triggered, including:
[0369] After determining that the first physical resource has failed to transmit, a third transmission failure report is triggered, which includes the transmission failure information corresponding to the first physical resource.
[0370] Based on the second condition, determine whether it is necessary to trigger the first transmission failure report or the second transmission failure report within the second time period according to the transmission status of the second physical resource.
[0371] If the second condition is met, a first transmission failure report or a second transmission failure report is triggered based on the transmission status of the second physical resource during the second time period.
[0372] Furthermore, if it is determined that the second physical resource also experienced a transmission failure, the first transmission failure report is triggered; or, if it is determined that the second physical resource did not experience a transmission failure during the second time period, the second transmission failure report is triggered.
[0373] If the second condition is not met, then if the second physical resource also fails to transmit after the first physical resource fails to transmit, the first transmission failure report is triggered; or, if the second physical resource does not fail to transmit after the first physical resource fails to transmit, the second transmission failure report is triggered.
[0374] In Method 4, unlike Methods 1 and 2, after detecting a failure in the first BFD RS set, a transmission failure report corresponding to the first BFD RS set is triggered first. For distinction, this triggered report is called the third transmission failure report. After triggering the third transmission failure report, it is necessary to determine, based on the second condition, whether to trigger either the first or second transmission failure report within the second time period according to the transmission status of the second physical resource.
[0375] In this method embodiment, the implementation of waiting for a period of time can also include the two methods mentioned above, namely, timing the second time period based on a timer and determining the transmission status of the second physical resource at or before a fixed time point.
[0376] In the implementation of timing the second time period based on a timer, the step of triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource, when it is determined that the first physical resource has experienced a transmission failure, includes:
[0377] When it is determined that the first physical resource has failed to transmit, a first timer is started to time the second time period; or
[0378] When it is determined that the first physical resource has failed to transmit, the transmission failure indicator timer corresponding to the first physical resource is reused as a second timer, and the second timer is started to count the second time period.
[0379] Optionally, the method embodiments further include:
[0380] If, during or after the first or second timer expires, it is determined that the second physical resource also experienced a transmission failure, then the first transmission failure report is triggered; or,
[0381] If, during the timing of the first or second timer or after its timeout, it is determined that the second physical resource has not experienced a transmission failure, then a second transmission failure report is triggered; or,
[0382] If the transmission failure indicator counters corresponding to the first physical resource and the second physical resource reach their maximum values, the first transmission failure report is triggered; or,
[0383] When the transmission failure indicator counter corresponding to the second physical resource reaches its maximum value, the second transmission failure report is triggered.
[0384] In the implementation of determining the transmission status of a second physical resource at or before a fixed time point, the step of determining whether to trigger a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource within a second time period, based on a second condition, includes:
[0385] Based on the second condition, at the second time point or at a time point before the second time point after determining that the first physical resource has experienced a transmission failure, if it is determined that the second physical resource has also experienced a transmission failure, then the first transmission failure report is triggered; or
[0386] Based on the second condition, at the second time point or at a time point before the second time point after determining that the first physical resource has failed to transmit, if it is not determined that the second physical resource has failed to transmit, then the second transmission failure reporting is triggered, or the triggering of the second transmission failure reporting is suspended.
[0387] For details regarding the two implementation methods for waiting for a period of time, as well as the introduction of a new first timer or the reuse of an existing timer as a second timer, please refer to the descriptions in the above embodiments, which will not be repeated here.
[0388] In this embodiment of the method, if the terminal device triggers a transmission failure report corresponding to two BFD RS sets at the second time point, the subsequent processing method for the previously triggered third transmission failure report includes at least one of the following:
[0389] Cancel the third transmission failure report; or
[0390] Continue sending the third transmission failure report, that is, continue sending the transmission failure report corresponding to the first BFD RS set that was triggered earlier; or
[0391] The third transmission failure report can be retained, suspended, or delayed. For example, if no response is received from the gNB for the transmission failure reports corresponding to the two BFD RSsets within a certain period of time, the terminal device can continue to send the transmission failure reports corresponding to the two BFD RSsets respectively, so that the previously multiplexed and assembled BFR MAC CE can continue to be used.
[0392] Alternatively, the second time point can be:
[0393] Determine the time point at which the transmission of the first physical resource failed; or
[0394] Determine the time point after a preset duration has elapsed following the transmission failure of the first physical resource; or
[0395] Determine the time point at which the first cell-level transmission failure event is triggered or the first cell-level transmission failure is reported after the first physical resource transmission failure occurs; or
[0396] Determine the time point at which the first transmission failure is triggered or reported after the first physical resource experiences a transmission failure; or
[0397] The time point determined from two candidate time points according to the nearest, farthest, maximum, or minimum value, wherein the two candidate time points include a first fixed time point and the time point at which the first cell-level transmission failure event is triggered or reported after determining that the first physical resource has experienced a transmission failure; or
[0398] The time point determined from two candidate time points according to the nearest, farthest, maximum, or minimum value, wherein the two candidate time points include a second fixed time point and the time point at which the first transmission failure is triggered or reported after the first physical resource transmission failure occurs; or
[0399] The time point corresponding to the timeout of the timer (including the first timer or the second timer).
[0400] The method for determining the second time point described in this embodiment can be the same as the method for determining the first time point described above. Please refer to the above embodiment for details, which will not be repeated here.
[0401] Optionally, determining that the second condition is satisfied includes any of the following:
[0402] The transmission failure indication counter corresponding to the second physical resource is greater than 0, or greater than a certain value (this value can be a value configured by the network-side device, or a predefined value, such as 1 / 2, 1 / 3, etc. of the maximum number of times).
[0403] The transmission failure indication counter corresponding to the second physical resource is greater than a fixed value; the fixed value is configured on the network side or predefined.
[0404] The transmission quality parameters are worse than the threshold.
[0405] Receiving configuration or instructions from the network side can specifically mean that the terminal device receives configuration from the network side device, notifying the terminal device to start or restart the first timer or the second timer for the cell, or all cells corresponding to the terminal device, or at least one BFDRS set of the terminal device, or determining a transmission failure event at a first time point.
[0406] Specifically, in this method embodiment, at the second time point, a transmission failure event or a triggered transmission failure report is determined based on a second condition. For example, the second condition can be the same as the first condition. For instance, even if the second BFD RS set does not experience a transmission failure, but the counter of the second BFD RS set meets certain conditions, such as the timer beamFailureDetectionTimer corresponding to the second BFD RS set receiving at least one failure indication during its runtime, the terminal device can initiate transmission failure reports for both BFD RS sets at the second time point, or use the transmission failure report of the first BFD RS set to carry information that both BFD RS sets have experienced transmission failures. For example, if the physical channels used for reporting transmission failures of one BFD RS set and two BFD RS sets are different—for instance, the former uses PUSCH to send the BFR MAC CE and the latter uses PRACH to carry the preamble—then at the second time point, transmission failure reports for both BFD RS sets can be initiated, i.e., transmission failure reports are sent using PRACH. Alternatively, if the physical channels used for reporting transmission failures of one BFD RS set and two BFD RS sets are the same—for instance, both use PUSCH to send the BFR MAC CE—then the transmission failure report for the first BFD RS set can carry information indicating that both BFD RS sets have failed, i.e., the BFR MAC CE carries the transmission failure information for both the first and second BFD RS sets.
[0407] The second condition can also be a configuration or instruction from the network-side device. For example, the network-side device may instruct the terminal device to report the failure of two BFD RS sets when the first BFD RS set fails. Or, the network-side device may configure the terminal device to only perform cell-level BFR reporting. In order to quickly recover from transmission failure, the terminal device may also send the transmission failure reports corresponding to the two BFD RS sets in advance before all two BFD RS sets have experienced transmission failure events.
[0408] Method 5 for achieving joint reporting:
[0409] The terminal device determines the transmission failure event based on the third time point, and then triggers the transmission failure report corresponding to the transmission failure event.
[0410] Specifically, the step of triggering a first transmission failure report or a second transmission failure report based on the transmission status of the second physical resource, when it is determined that a transmission failure has occurred in the first physical resource, includes:
[0411] If, after determining that the first physical resource has experienced a transmission failure, the second physical resource also experiences a transmission failure at a third time point, then the first transmission failure report is triggered; or
[0412] If, at a third time point, it is determined that the second physical resource has not experienced a transmission failure after the first physical resource has been determined to have experienced a transmission failure, then the second transmission failure report is triggered.
[0413] The third time point can be either the first time point or the second time point mentioned above. Specifically, the third time point can be determined based on any of the following methods:
[0414] Determine the time point at which the transmission of the first physical resource failed; or
[0415] Determine the time point after a preset duration has elapsed following the transmission failure of the first physical resource; or
[0416] Determine the time point at which the first cell-level transmission failure event is triggered after the first physical resource experiences a transmission failure; or
[0417] Determine the time point at which the first transmission failure is reported after the first physical resource experiences a transmission failure; or
[0418] The time point determined from two candidate time points according to the nearest, farthest, maximum, or minimum value, wherein the two candidate time points include a first fixed time point and the time point at which the first cell-level transmission failure event is triggered after the transmission failure of the first physical resource is determined; or
[0419] The time point determined from the two candidate time points according to the nearest, farthest, maximum or minimum value, the two candidate time points include a second fixed time point and the time point at which the first transmission failure is reported after the first physical resource has experienced a transmission failure.
[0420] The time point corresponding to the timer timeout.
[0421] The difference from the above implementation methods is that Method 5 does not impose any restrictions or regulations on the actions to be performed by the terminal device before the third time point. The terminal device can determine its behavior before the third time point arrives, based on its own implementation, when a BFD RS set is judged to have caused a transmission failure. For example, it can be stipulated that when the third time point is reached, the transmission failure event is determined and the corresponding report is made.
[0422] When at least one cell is configured with at least two BFD RS sets, the terminal device determines a transmission failure event based on a third time point and then triggers a transmission failure report corresponding to the transmission failure event. If one BFD RS set experiences a transmission failure at the third time point, the terminal device triggers a transmission failure report corresponding to one BFD RS set; if two or more BFD RS sets experience transmission failures at the third time point, the terminal device triggers a transmission failure report corresponding to two BFD RS sets, or a cell-level transmission failure report.
[0423] For example, if one TRP (BFD-RS set) fails to transmit, and two TRPs fail to transmit, the reporting method is similar to that of Rel-16 SCell transmission failure, i.e., LRR+BFR MAC-CE. Alternatively, if two TRPs fail to transmit, the RACH method can be used for reporting. The transmission failure event and the corresponding report can be determined based on at least one of the following third time points:
[0424] Method A-1: The terminal device determines the number of failed BFD-RS sets carried in the BFR MAC CE based on the number of failed BFD-RS sets at the transmission time of the first BFD RS set or any other BFD RS set or the BFR MAC CE corresponding to the cell, regardless of whether the SR is triggered by the failure event of 1 or 2 BFD-RS sets.
[0425] Method A-2: The terminal device determines the number of failed BFD RS sets carried in the BFR MAC-CE based on the number of failures of the first BFD RS set or any other BFD RS set or the SR trigger time (which is also the LRR transmission time) corresponding to the cell.
[0426] Method A-3: The terminal device determines the number of failed BFD-RS sets carried in the BFR MAC-CE based on the number of failed BFD-RS sets during the multiplexing and reassembly of the first BFD RS set or any other BFD RS set or the BFR MAC CE corresponding to the cell, regardless of whether the SR is triggered by the failure event of 1 or 2 BFD-RS sets.
[0427] Optionally, based on the above-described method embodiments, the method may further include:
[0428] Based on network-side configuration and / or predefined methods, the terminal device determines whether or how to use the above mechanism after determining that the first physical resource has experienced a transmission failure, according to the transmission status of the second physical resource.
[0429] Optionally, the configuration method may include: directly configuring whether to use joint transmission failure reporting of two BFD RS sets. If configured, when one BFD RS set fails to transmit, the terminal device can determine whether the other BFD RS set has also failed to transmit and trigger the corresponding reporting behavior through the mechanism in the above embodiment. If not configured, the terminal device will directly trigger the corresponding transmission failure reporting when one BFD RS set fails to transmit.
[0430] The predefined method can be at least one of the following:
[0431] It was determined that SpCell uses a joint reporting method with two BFD RS sets, while SCell does not use this method;
[0432] When a network-side device is configured to report cell-level transmission failures, or to report both cell-level and TRP-level transmission failures, the terminal device can determine to use a joint reporting method of two BFD RS sets.
[0433] The granularity of configuration can be at the cell level, the terminal level, or at least one of the physical resources, such as the BFD RS set level.
[0434] The method for reporting the first transmission failure may include:
[0435] Initiate transmission failure reports for the two physical resources; or
[0436] The transmission failure report corresponding to the first physical resource carries information indicating that both physical resources have experienced transmission failures.
[0437] Optionally, the transmission failure is determined based on the maximum number of transmission failure indication counters corresponding to the physical resources.
[0438] Specifically, in this method embodiment, the terminal device can determine when to use the mechanisms in the above embodiments through explicit signaling configuration of the network-side device, and can also determine whether or how to use the mechanisms in the embodiments through a predefined method.
[0439] For example, network-side equipment can configure BFR detection and reporting mechanisms for each cell. For instance, it can be directly configured whether to use joint transmission failure reporting for two BFD RS sets. If so, when one BFD RS set fails, the terminal device can use the mechanisms described in various embodiments to determine whether the other BFD RS set has also failed and trigger the corresponding reporting behavior. If not, the terminal device will directly trigger the corresponding transmission failure report when one BFD RS set fails.
[0440] The configuration granularity can be at the cell level. For example, cells A and B can use a combined transmission failure report with two BFD RS sets, while cells C and D cannot. The UE can also be configured with a set of cells that can use a combined transmission failure report with two or more BFD RS sets.
[0441] The configuration granularity can also be at the UE level. For example, it can configure whether the UE can support joint transmission failure reporting of two BFD RS sets. If it can, then all serving cells can support joint transmission failure reporting of two BFD RS sets; otherwise, all serving cells cannot support joint transmission failure reporting of two BFD RS sets. Before the network-side equipment configuration, the terminal device can also report whether it supports the capability of joint reporting of two BFD RS sets. If the corresponding capability is supported, the network-side equipment may configure the terminal device to use joint transmission failure reporting of two BFD RS sets; otherwise, it will not configure the terminal device to use joint transmission failure reporting of two BFD RS sets.
[0442] The configuration granularity can also be at the BFD RS set level. For example, when a BFD RS set experiences a transmission failure, the terminal device can use any of the methods described in the above embodiments to continue determining whether another BFD RS set has also experienced a transmission failure event. Accordingly, after receiving the configuration from the network-side device, the terminal device will continue to determine whether another BFD RS set has also experienced a transmission failure event according to any of the methods described in the above embodiments. If both BFD RS sets experience transmission failures, then the terminal device will initiate transmission failure reports for both BFD RS sets.
[0443] The UE can be configured using RRC signaling and / or MAC-CE signaling and / or DCI signaling.
[0444] The terminal device can also determine whether or how to use the mechanism in Examples 1-3, namely, the joint transmission failure reporting of two BFD RS sets, through a predefined method. For example, the terminal device can determine that SpCell adopts the joint reporting method of two BFD RS sets, while SCell does not adopt this method; or when the network-side device is configured to perform cell-level transmission failure reporting, or cell-level and TRP-level transmission failure reporting, the terminal device can determine to adopt the joint reporting method of two BFD RS sets.
[0445] The terminal device can also determine whether to use the joint transmission failure reporting method of two BFD RS sets based on the configuration and predefined methods of the network-side device. For example, when the network-side device configures the UE to perform joint transmission failure reporting of two BFD RS sets, the UE can determine that SpCell uses the joint reporting method of two BFD RS sets, while SCell does not use this method. Any of the configuration methods and predefined methods mentioned above can be combined, and this embodiment does not impose any restrictions on this.
[0446] Based on the transmission failure reporting method proposed in the various method embodiments of this application, the terminal device can jointly determine the transmission failure of multiple BFD RS sets in a cell, and then jointly report the transmission failure of two BFD RS sets, avoiding always reporting independently for each BFD RS set and improving reporting efficiency.
