Background

Typically, the terminal periodically receives and measures a beam failure detection Reference Signal (Beam Failure Detection-Reference Signal, RS, BFD-RS), and determines whether a beam failure event occurs based on the measurement result.

However, according to the scheme in the related art, the terminal may still default to the beam failure event and report the beam failure instance (Beam Failure Instance, BFI).

The beam detection method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 2, the present embodiment provides a beam detection method 200, which may be performed by a terminal, in other words, by software or hardware installed in the terminal, including the following steps.

S202: the terminal preferentially detects a beam failure detection Reference Signal (Beam Failure Detection-Reference Signal, RS, BFD-RS) through a highest priority transmission configuration indication (Transmission Configuration Indicator, TCI) state (state).

Wherein the terminal is configured with a plurality of TCI states, each TCI state of the plurality of TCI states corresponding to a priority. In this embodiment, the network side device may configure a priority for each TCI state; alternatively, the priority corresponding to the TCI state may be equal to the priority of the BFD-RS, where the network side device may configure the priority for the BFD-RS, and the configuration of the BFD-RS may include the TCI state.

Before the embodiment is executed, a beam training process may be performed between the terminal and the network side device, so as to determine an optimal beam, where the optimal beam may be a beam corresponding to the TCI state with the highest priority.

In this embodiment, the terminal preferentially detects the BFD-RS through the TCI state with the highest priority, and at the same time, the terminal also preferentially receives data, signaling, and the like through the TCI state with the highest priority. For the network side device, the network side device also sends BFD-RS preferentially through the TCI state with the highest priority, and sends data, signaling, and the like preferentially through the TCI state with the highest priority.

S204: and if the BFD-RS is not detected through the TCI state with the highest priority, detecting the BFD-RS through the TCI state with the secondary priority or detecting a plurality of BFD-RSs through a plurality of TCI states, and selecting a BFD-RS link according to the signal quality of the plurality of BFD-RSs.

The BFD-RS may be periodically transmitted, and thus, the BFD-RS mentioned in this step may not be detected within one detection period; it is also possible that no BFD-RS is detected for a number of consecutive periods. The reference to the undetected BFD-RS in this embodiment may be that the signal quality of the detected BFD-RS is lower than a certain threshold, where the signal quality may be determined by reference to a parameter index such as received signal power (Reference Signal Receiving Power, RSRP), signal-to-interference-plus-noise ratio (Signal to Interference plus Noise Ratio, SINR), BLock Error Rate (BLER), etc.

The second highest priority mentioned in this step may be the second highest priority.

In this embodiment, for example, the network side device configures the terminal with TCI state 1, TCI state 2 and TCI state 3, where the priority of TCI state 1 is the highest and the priority of TCI state 3 is the lowest. The terminal preferentially detects BFD-RS and receives data, signaling and the like through the wave beam corresponding to the TCI state 1; if BFD-RS is not detected by the beam corresponding to the TCI state 1, detecting BFD-RS, receiving data, signaling and the like by the beam corresponding to the TCI state 2; or detecting BFD-RS through the beams corresponding to the TCI state 1, the TCI state 2 and the TCI state 3, and if the terminal detects that the signal quality of the BFD-RS on the beam corresponding to the TCI state 2 is highest, detecting BFD-RS, receiving data, signaling and the like through the beam corresponding to the TCI state 2.

According to the beam detection method provided by the embodiment of the application, the network side equipment configures a plurality of TCI states for the terminal, each TCI state corresponds to a priority, the terminal preferentially detects BFD-RS through the TCI state with the highest priority, if BFD-RS is not detected through the TCI state with the highest priority in the follow-up process, BFD-RS can be detected through the TCI state with the secondary priority, or a plurality of BFD-RSs are detected through the plurality of TCI states at the same time, and BFD-RS links are selected according to the signal quality of the plurality of BFD-RSs.

Optionally, on the basis of embodiment 200, the method further includes: the terminal sends feedback information through a beam corresponding to a first TCI state, wherein the feedback information is used for determining whether the beam corresponding to the first TCI state fails, and the first TCI state is one of a plurality of TCI states configured for the terminal.

In this embodiment, for example, when the terminal detects the BFD-RS through the TCI state with the highest priority, the terminal may send feedback information through the beam corresponding to the TCI state with the highest priority, so that the network side device may determine the quality of the beam corresponding to the TCI state with the highest priority according to whether the feedback information is received or not, or according to the content of the feedback information.

Specifically, for example, the feedback information occupies 1 bit, and the terminal periodically sends 1 bit of feedback information to tell the network side that the beam link corresponding to the TCI state with the highest current priority is good. If the network side device does not receive the feedback information in a certain period or does not receive the feedback information in a plurality of continuous periods, the network side device considers that the beam corresponding to the TCI state with the highest priority has a problem, and can send BFD-RS, data, signaling and the like through the beam corresponding to the TCI state with the second priority.

For another example, the feedback information occupies 1 bit, the terminal periodically sends the feedback information, or sends the feedback information under the triggering of the network side device, and "1" represents that the beam link corresponding to the TCI state with the highest current priority is good; "0" represents that the beam link quality corresponding to the TCI state with the highest current priority is poor.

It is to be understood that the first TCI state may be referred to as a TCI state currently used by the terminal, and may include not only the TCI state with the highest priority, but also the TCI state with the secondary priority used by the terminal after S204.

Optionally, the sending, by the terminal, feedback information through the beam corresponding to the first TCI state includes: the terminal sends feedback information through a beam corresponding to a first TCI state according to a first principle; wherein the first principle comprises one of the following: 1) A periodic transmission, wherein the period can be predefined by network side equipment configuration or protocol; 2) And according to the triggering of the network side equipment, aperiodic or periodic transmission is carried out.

The above mentioned network side device configuration or network side device trigger may be configured directly by RRC; or configured by RRC, downlink control information (Downlink Control Information, DCI) to select one case; or may be directly configured by DCI.

Optionally, the method further comprises: the terminal receives first configuration information, wherein the first configuration information is used for configuring at least one of the following related feedback information: start time, stop time, duration, period, interval, time-frequency position.

The terminal sending feedback information through the beam corresponding to the first TCI state according to the first principle includes: the terminal sends feedback information on a first channel through a beam corresponding to a first TCI state according to a first principle; wherein the first channel comprises at least one of the following 1) and 2):

1) A physical random access channel (Physical Random Access Channel, PRACH) corresponding to a beam corresponding to the first TCI state. For example, the terminal feeds back information on the PRACH, where the PRACH has a correspondence with the BFD-RS (e.g. SSB/CSI-RS), and the BFD-RS also has a correspondence with the first TCI state, for example, the BFD-RS has a one-to-one correspondence with the TCI state. At this time, the feedback information may be a Preamble (Preamble) sequence, which is not required to carry additional information or bits, so as to save signaling resource overhead. After receiving the PRACH, the network side equipment knows which TCI state of which BFD-RS it corresponds to.

2) A physical uplink channel; wherein, the physical uplink channel has a corresponding relation with the first TCI state or has no corresponding relation. The physical uplink channel may include a physical uplink control channel (Physical Uplink Control Channel, PUCCH) or a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH), etc. The feedback information can be indicated explicitly, namely, bit digital display indication is used; the feedback information may also be implicitly indicated, for example, with a sequence length, a sequence cyclic shift, a sequence position, etc.

Under the condition that the physical uplink channel and the first TCI state have a corresponding relation, after receiving the physical uplink channel, the network side equipment knows which TCI state of which BFD-RS the network side equipment corresponds to, does not need additional signaling to indicate the TCI state, and is convenient for saving signaling resource expenditure.

The foregoing embodiment mentions that when the terminal detects the BFD-RS through the TCI state with the highest priority, the terminal may send feedback information through the beam corresponding to the TCI state with the highest priority, after the terminal sends the feedback information, the terminal may also detect the BFD-RS through the TCI state with the highest priority within a certain time, and if no corresponding BFD-RS is detected, the terminal detects the BFD-RS on the BFD-RS corresponding to the second priority or the sub-priority within a subsequent fixed time period, where the subsequent fixed time period may be predefined by the protocol. In this embodiment, the network side device may send information on beams with different priorities according to whether feedback information is received. That is, if the network side device receives the feedback information, the BFD-RS with the highest priority is still sent. And if the feedback information is not received, sending the RS with the secondary priority or the second priority.

Or the terminal detects the BFD-RS through the TCI state with the highest priority in a certain time, if the corresponding BFD-RS is not detected, the terminal detects a plurality of BFD-RSs at the same time in a certain time, and selects the corresponding BFD-RS link according to the received signal quality. The signal quality can be judged by parameter indexes such as RSRP/SINR/BLER. The parameter index may be predefined for the protocol or the terminal may implement itself. In this embodiment, according to whether feedback information is received or not or whether the feedback information indicates that the quality of the signal received by the terminal is poor, the network side device sends information on all configured beams.

The network side device mentioned in the above two examples depends on whether feedback information is received or not. The decision criterion may be that the network side device sends a BFD-RS of a secondary priority or a second priority each time feedback information is not received; or if the feedback information which is not received by the network side equipment meets a certain condition, the BFD-RS of the secondary priority or the second priority is sent.

The feedback information which is not received by the network side equipment meets a certain condition. It may be that no fixed number of feedback information is received for a fixed time, the fixed time and the fixed number being predefined by the protocol. In a specific example, a counter may be set, the timer duration and the counter maximum value being predefined by the protocol/network side device. The network side equipment does not receive the feedback signal, and then the counter is +1, and then the timer resets the timing. If the feedback is received in the time length of the timer, resetting and resetting the counter.

Alternatively, the foregoing embodiments refer to the network side device configuring multiple TCI states and priorities for the terminal, and will be described in two examples.

In one example, the terminal may obtain the second configuration information by receiving second configuration information, where the second configuration information is used to configure a BFD-RS for the terminal, and the BFD-RS configured for the terminal includes the plurality of TCI states, and each TCI state in the plurality of TCI states corresponds to a priority. For example, the second configuration information configures the terminal with a plurality of or multiple sets of BFD-RSs, each set or set of BFD-RSs corresponding to one TCI state. In this example, the network side device may explicitly configure the plurality of TCI states through the second configuration information and each TCI state corresponds to a priority.

In another example, the terminal may obtain the third configuration information by receiving third configuration information, where the third configuration information is used to configure a Control Resource SET (CORESET) for the terminal, and the CORESET includes the plurality of TCI states, where each TCI state in the plurality of TCI states corresponds to a priority. The BFD-RS is determined by the highest priority TCI state among the activated TCI states corresponding to the physical downlink control channel (Physical Downlink Control Channel, PDCCH), for example. That is, there are multiple TCI states in the CORESET preconfigured by the network side device, and corresponding priorities are configured. In this example, the network side device can implicitly configure multiple TCI states and each TCI state corresponds to a priority through the third configuration information

Optionally, each of the plurality of TCI states corresponds to a priority indicated directly by the indication information; or according to the identification size or the configuration sequence of each TCI state, for example, the smaller the identification of the TCI state is, the higher the priority is; the earlier the TCI state is configured, the higher the priority, etc.

The number of the plurality of TCI states, and the priority configuration may be dynamically updated. The updating is performed by the network-side device, may be performed by a radio resource control (Radio Resource Control, RRC) or a medium access control unit (Media Access Control Control Element, MAC CE),

in one example, the method further comprises: the terminal receives a configuration update message, wherein the configuration update message is used for updating at least one of the following: the number of the plurality of TCI states; and the priority corresponding to at least one TCI state in the plurality of TCI states.

In order to describe the beam detection method provided in the embodiments of the present application in detail, the following description will be made with reference to several specific embodiments.

Example 1

Before this embodiment is performed, the configuration of BFD-RS by the network side device (e.g., base station) is as follows: the base station configures multiple TCI states (states) for each BFD-RS or CORESET (assuming 3 beams: beam1, beam2, beam 3). Each TCI state configures a corresponding priority (assuming the priority order is beam1> beam2> beam 3).

Note that, the TCI state information of the RRC dynamic configuration CORESET generally means that the multiple tcistates are adjacent beams (beams).

The base station preferably transmits information on the beam with the highest TCI state priority (assumed to be beam 1), and the UE also preferably receives information on the beam with the highest TCI state priority (beam 1). The number of TCI states and the priority order can be dynamically controlled by the network side RRC layer.

The base station uploads the configuration of feedback information to the UE: 1, a base station pre-configures a period of a UE uploading feedback signal; 2, or the base station triggers the UE to upload feedback information in some way, which may be configured directly by RRC. The DCI selection may also be implemented by RRC configuration. Or may be directly configured by DCI. The configuration includes at least one of the following 1) to 5).

1) Starting feedback information;

2) The time of suspension of the feedback information.

3) The duration of the feedback information.

4) Period/interval of feedback information.

5) And feeding back the time-frequency position of the information.

This embodiment includes the steps of:

step 1: the UE detects the BFD-RS signal (on beam 1) which is a type D quasi co-located (QCL type D) relationship with the highest priority TCI state in CORESET.

Step 2: the UE may report current beam information for a certain period of time and/or periodically. Telling the base station whether the current beam link was successful. The reporting may be based on the channel in 1) or 2) as follows.

1) Feedback information may be uploaded through PRACH. The PRACH has a correspondence with BFD-RS (SSB). At this time, the feedback information is a Preamble sequence, and no extra information or bits need to be carried. After receiving the PRACH, the base station knows which BFD-RS (SSB) it corresponds to.

2) Feedback information may be uploaded through PUCCH/PUSCH. The channel may have a correspondence with BFD-RS, i.e. similar to the correspondence of PRACH channels with SSB channels. The channel may also have no correspondence to the BFD-RS, which uploads feedback information on the beam (beam 1) corresponding to the BFD-RS.

The feedback information may display an indication, namely a bit digital display indication; the feedback information may be implicitly indicated, i.e. implicitly indicated by sequence length, sequence cyclic shift, sequence position, etc.

Step 3: if the base station receives the feedback information uploaded by the UE, the base station proves that the beam does not fail (failure), so that the base station continues to transmit information on the beam (beam 1) with the highest TCI state priority. If the base station does not receive the feedback information uploaded by the UE, the base station proves that the beam fails, and therefore the base station transmits information on the beam (beam 2) of the next priority. The base station may not receive the feedback information uploaded by the UE, where the decision criteria may be one of the following:

1. And each time the base station does not receive the feedback information, sending the RS with the secondary priority or the second priority.

2. And if the feedback information which is not received by the base station meets a certain condition, sending the RS with the secondary priority or the second priority.

The above conditions may be: no fixed number of feedback information is received for a fixed time, which fixed time and fixed number may be predefined by the protocol. Alternatively, a counter may be set, the timer duration and the counter maximum value being pre-configured by the protocol pre-definition/base station. And if the base station does not receive the feedback information, the counter is +1, and then the timer resets to count. If the feedback information is received in the time length of the timer, resetting and resetting the counter.

Step 4: the UE detects the beam (beam 1) with the highest priority in a certain time, if the beam information is detected, the UE proves that a beam failure event is not formed, and continues to use the beam1 connection for data transmission; if the beam information is not detected, the sub-priority beam (beam 2) information is continuously detected, and if the beam2 is successfully detected, the UE uses the beam2 for data receiving. Or the UE detects a plurality of BFD-RSs at the same time in a certain time, and selects a corresponding BFD-RS link according to the received signal quality.

Example two

This embodiment performs the previous configuration procedure with reference to embodiment one, which includes the steps of:

step 1: the UE detects the BFD-RS signal (on beam 1) which is related to the highest priority TCI state QCL type D in CORESET.

1) Feedback information may be uploaded through PRACH. The PRACH has a correspondence with BFD-RS (SSB). At this time, the feedback information is the Preamble sequence, and no extra information or bit is required to be carried. After receiving the PRACH, the base station knows which BFD-RS (SSB) it corresponds to.

Step 3: if the base station receives the feedback information uploaded by the UE, the feedback information shows that the quality of the currently linked beam signal is poor, or the base station does not receive the feedback information uploaded by the UE. The base station transmits information on all priority beams, i.e. similar to PDCCH repetition (repetition), the PDCCH carries other information in agreement, but the corresponding beams are not.

The beam detection method according to the embodiment of the present application is described in detail above in connection with fig. 2. A beam detection method according to another embodiment of the present application will be described in detail below with reference to fig. 3. It will be appreciated that the interaction of the network side device with the terminal described from the network side device is the same as or corresponds to the description of the terminal side in the method shown in fig. 2, and the relevant description is omitted as appropriate to avoid repetition.

Fig. 3 is a schematic flow chart of an implementation of a beam detection method in an embodiment of the present application, which may be applied to a network side device. As shown in fig. 3, the method 300 includes the following steps.

S302: the network side equipment transmits BFD-RS preferentially through the wave beam corresponding to the TCI state with the highest priority.
