Description

Technical Field

[0001] Embodiments of the present application relate to technical fields such as BFD (beam - failure detection), and in particular, to a communication method and apparatus. Background Art

[0002] When beam alignment is performed between a base station and a terminal, the maximum link gain can be obtained. Currently, the terminal determines whether the current beam meets the communication quality requirements by monitoring the quality of the current reference signal.

[0095] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Embodiments

[0096] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0097] It should be noted that in this document, the term "including", "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. When there is no further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the process, method, article or device including that element.

[0098] In this application, the term "including" and its variants may refer to non-limiting inclusion; the term "or" and its variants may refer to "and / or". In this application, terms such as "first", "second", etc. are used to distinguish similar objects and do not necessarily describe a specific order or sequence. In this application, "a plurality of" means two or more. "And / or" describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0099] First, in combination with Figure 1 and Figure 2 the related technologies will be described.

[0100] Figure 1 It is a schematic diagram of a related technology scenario. As Figure 1 shown, within the timing duration T of the beam failure detection timer (beamFailureDetectionTimer), if the number of consecutive beam failure instances (beam-failure instance) exceeds the configured maximum count of beam failure instances (beamFailureInstanceMaxCount), it is considered that a beam failure is detected. When the L1-RSRP (Reference Signal Receiving Power) obtained by the terminal from a single measurement of the reference signal is lower than a threshold (Threshold), it is considered that a beam failure instance occurs. Figure 1 It is illustrated by taking 4 consecutive beam failure instances within T as an example.

[0101] After the terminal discovers a beam failure, it measures the candidate beams, selects a suitable new beam from the candidate beams, and triggers the PRACH (Physical Random Access Channel) or MAC-CE (Media Access Control Control Element) to report the information of the new beam to the network device.

[0102] When the beam failure occurs in the Single-TRP (Transmission and Receiving Point) scenario, if the beam failure occurs in the PCell (Primary Cell), the PRACH is triggered, and the information of the new beam is carried by the PRACH; if the beam failure occurs in the Scell (Secondary Cell), the MAC-CE is triggered, and the information of the new beam is carried by the MAC-CE.

[0103] In Figure 1 it takes a period of time from when the terminal first detects the beam failure to when the PRACH or MAC-CE is triggered to report the information of the new beam, which will cause the communication interruption between the terminal and the network device.

[0104] In practical applications, when the beam failure occurs in the PCell, if the information of the new beam is carried by the MAC-CE, it will increase the flexibility and speed of communication.

[0105] Figure 2 It is a schematic diagram of the scenario of another related technology. As Figure 2 shown, when K1 beam failure instances are detected, the terminal adopts the AI prediction method. According to the beam measurement results of the K1 beam failure instances, it predicts in advance whether a beam failure will occur in the future. If it is predicted that a beam failure will occur, it measures the candidate beams, selects a suitable new beam from the candidate beams, and triggers the PRACH or MAC-CE to report the information of the new beam to the network device. For example Figure 2 it is illustrated with K equal to 4 as an example.

[0106] In Figure 2 it, since it can predict in advance whether a beam failure will occur in the future, it can measure the candidate beams and select a suitable new beam before the beam failure occurs, preventing the communication interruption between the terminal and the network device.

[0107] Although the terminal adopts the AI prediction method and can predict in advance whether a beam failure will occur in the future and can perform beam switching in advance when it is predicted that a beam failure will occur, the AI prediction method may make incorrect predictions, resulting in unnecessary beam switching.

[0108] Among them, the process of beam switching includes: selecting a suitable new beam, triggering the PRACH or MAC-CE to report the information of the new beam to the network device, etc.

[0109] To prevent unnecessary beam switching caused by prediction errors, an embodiment of the present application provides a communication method and apparatus. In this method, when the prediction result indicates that a beam failure will occur, the signal quality of a second reference signal is obtained, and it is determined whether the prediction result is abnormal according to the signal quality. When it is determined that the prediction result is abnormal, the beam switching is terminated, thereby avoiding the problem of unnecessary beam switching caused by prediction errors.

These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be elaborated in some embodiments.

[0118] Figure 3 It is one of the flow diagrams of the communication method provided by the embodiments of the present application. As Figure 3 shown, the method includes:

[0119] S301. The prediction result obtained by the terminal's intelligent prediction of the first reference signal indicates that beam failure will occur.

[0120] The first reference signal is a reference signal configured by the network device for the terminal.

[0121] The first reference signal can be, for example, BFD-RS (beam-failure detection-reference signal).

[0122] In some embodiments, the prediction result includes one or more of the following:

[0123] The signal quality of the first reference signal at a future moment;

[0124] The first indication information, which indicates whether beam failure will occur;

[0125] The time when beam failure will occur.

[0126] Optionally, the number of future time instants may be one or more.

[0127] In the embodiments of the present application, the signal quality may be any one of the following:

[0128] RSRP (Reference Signal Receiving Power);

[0129] RSRQ (Reference Signal Receiving Quality);

[0130] BLER (block error rate);

[0131] SINR (Signal to Interference plus Noise Ratio).

[0132] When the signal quality of the first reference signal at a future time instant does not meet the first preset condition, the prediction result indicates that a beam failure will occur.

[0133] When the signal quality is RSRP or RSRQ, the signal quality of the first reference signal at a future time instant not meeting the first preset condition includes: the signal quality of the first reference signal at at least one future time instant is less than or equal to the first threshold.

[0134] When the signal quality is BLER or SINR, the signal quality of the first reference signal at a future time instant not meeting the first preset condition includes: the signal quality of the first reference signal at at least one future time instant is greater than or equal to the second threshold.

[0135] The values of the first threshold and the second threshold can be set according to actual requirements, can follow the thresholds for beam failure detection in existing protocols, or can be new thresholds configured by the base station (i.e., different from the thresholds for beam failure detection in existing protocols).

[0136] The first threshold and the second threshold can be obtained from the same configuration, i.e., the first threshold and the second threshold are the same.

[0137] Optionally, the first indication information may further indicate whether a beam failure will occur within a preset time period.

[0138] The preset time period may be a future time period configured and / or indicated by the network device, or a future time period determined by the terminal.

[0139] Optionally, the first indication information may be a first identifier or a second identifier.

[0140] The first identifier and the second identifier are different.

[0141] For example, the first identifier is used to indicate that beam failure will occur, or beam failure will occur within a preset period.

[0142] For example, the second identifier is used to indicate that beam failure will not occur, or beam failure will not occur within a preset period.

[0143] When the first indication information is included in the prediction result, when the first indication information is the first identifier, the time when beam failure will occur may be included in the prediction result, and when the first indication information is the second identifier, the time when beam failure will occur may not be included in the prediction result.

[0144] S302. The network device sends a second reference signal to the terminal.

[0145] The second reference signal is a reference signal configured by the network device for the terminal.

[0146] The second reference signal may be, for example, a reference signal for beam failure detection (BFD-RS) in existing standards.

[0147] Optionally, the first reference signal and the second reference signal may be indicated by one resource set, or the first reference signal and the second reference signal may be indicated by two resource sets respectively.

[0148] When the first reference signal and the second reference signal are indicated by one resource set, the resource set includes at most two resources. For example, at most two resources are both used to indicate the first reference signal and the second reference signal.

[0149] Optionally, when the first reference signal and the second reference signal are indicated by two resource sets, the first reference signal is indicated by a pre-configured first resource set, and the second reference signal is indicated by a pre-configured second resource set.

[0150] S303. The terminal obtains the signal quality of the second reference signal, and terminates beam switching when it is determined that the prediction result is abnormal according to the signal quality of the second reference signal.

[0151] When the signal quality of the second reference signal meets a second preset condition, it is determined that the prediction result is abnormal, and when the signal quality of the second reference signal meets the second preset condition, it is determined that the prediction result is normal.

[0152] When the signal quality is RSRP or RSRQ or SINR, the signal quality of the second reference signal at a future moment does not meet the second preset condition, including: the signal quality of the second reference signal at a future moment is greater than or equal to a third threshold.

[0153] When the signal quality is BLER, the signal quality of the second reference signal at a future time does not meet the second preset condition, including: the signal quality of the second reference signal at a future time is less than or equal to the fourth threshold.

[0154] The values of the third threshold and the fourth threshold can be set according to actual requirements. The thresholds for wave speed failure detection in existing protocols can be used, or new thresholds configured by the network device (i.e., different from the thresholds for wave speed failure detection in existing protocols) can be used.

[0155] Optionally, the third threshold can be the same as the first threshold, and the fourth threshold can be the same as the second threshold.

[0156] In the embodiments of the present application, when the prediction result indicates that a beam failure will occur, the signal quality of the second reference signal is obtained. When it is determined that the prediction result is abnormal based on the signal quality of the second reference signal, the beam switching is terminated, which can prevent incorrect prediction results from causing unnecessary beam switching.

[0208] The starting moment of the first duration can be, for example, the moment when the terminal sends multiple new beam information.

[0220] Based on Mode 1, the method provided in this application further includes:

[0221] When the signal quality of the second reference signal meets the second preset condition (that is, the prediction result is determined to be normal according to the signal quality of the second reference signal), switch to the target beam after the first duration.

[0222] Based on Mode 2, the method provided in this application further includes: When the signal quality of the second reference signal meets the second preset condition, switch to the new beam after the second duration.
