Background technique

The 5G new air interface (NR) system may work in the high frequency band of 6-100GHz, and the coverage of the common control channel and even the data channel is guaranteed by introducing multi-beam deployment. The quality of high-frequency beams changes quickly and is easily blocked, and beam failure (Beam Failure) may occur. When a terminal (such as UE, the following uses UE as an example) has beam failure detection (BFD, Beam Failure Detection), it may A beam failure recovery (BFR, Beam Failure Recovery) process will be initiated.

Figure 1 shows the interaction flow between the UE and the base station in the above-mentioned BFD process. The base station configures BFD and BFR-related parameters for the UE, such as the length of time to detect BFD, that is, beamFailureDetectionTimer, which is referred to as BFD in this article. Timer (for ease of description, it is also referred to as timer in this article), the maximum number of beam failure instance indications, that is, the threshold beamFailureInstanceMaxCount, the quality threshold of the BFR beam (for ease of description, it is also called count in this article), Candidate beam list and dedicated random access resources, etc. The UE judges whether BFD has occurred according to the above two parameters, namely timer and count. When a BFD occurs, the UE starts the BFR process.

In addition, features described with reference to certain examples may be combined in other examples.

Please refer to FIG. 2, which shows a block diagram of a wireless communication system to which the embodiments of the present disclosure are applicable. The wireless communication system includes a terminal 21 and a network device 22. Among them, the terminal 21 may also be referred to as a user terminal or a user equipment (UE, User Equipment), and the terminal 21 may be a mobile phone, a tablet (Personal Computer), a laptop (Laptop Computer), or a personal digital assistant (Personal Digital Assistant). , PDA), mobile Internet device (Mobile Internet Device, MID), wearable device (Wearable Device) or vehicle-mounted device and other terminal side devices, it should be noted that the specific type of terminal 21 is not limited in the embodiments of the present disclosure . The network device 22 may be an RRH, a base station, or a core network element, where the above-mentioned base station may be a base station of 5G and later versions (for example: gNB, 5G NR NB, etc.), or a base station in other communication systems (for example: eNB, WLAN Access point, or other access points, etc.), where the base station can be called Node B, Evolved Node B, Access Point, Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (Basic Service Set, BSS), Extended Service Set (Extended Service Set, ESS), Node B, Evolved Node B (eNB), Home Node B, Home Evolved Node B, WLAN Access Point, WiFi Node, RRH or some other suitable term in the field, as long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiments of the present disclosure, only the base station in the NR system is taken as an example. However, the specific type of base station is not limited.

The base station may communicate with the terminal 21 under the control of the base station controller. In various examples, the base station controller may be a part of the core network or some base stations. Some base stations can communicate control information or user data with the core network through the backhaul. In some examples, some of these base stations may directly or indirectly communicate with each other through a backhaul link, which may be a wired or wireless communication link. The wireless communication system can support operations on multiple carriers (waveform signals of different frequencies). Multi-carrier transmitters can simultaneously transmit modulated signals on these multiple carriers. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal can be sent on a different carrier and can carry control information (for example, reference signals, control channels, etc.), overhead information, data, and so on.

The base station can wirelessly communicate with the terminal 21 via one or more access point antennas. Each base station can provide communication coverage for its corresponding coverage area. The coverage area of an access point can be divided into sectors that constitute only a part of the coverage area. The wireless communication system may include different types of base stations (for example, macro base stations, micro base stations, or pico base stations). The base station can also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations can be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication link in the wireless communication system may include an uplink for carrying uplink (UL) transmission (for example, from the terminal 21 to the network device 22), or for carrying a downlink (DL) Transmission (for example, from network device 22 to terminal 21) downlink. UL transmission may also be referred to as reverse link transmission, and DL transmission may also be referred to as forward link transmission. Downlink transmission can use licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmission can be performed using licensed frequency bands, unlicensed frequency bands, or both.

As described in the background art, for BFD, the terminal (such as UE) determines whether to generate BFD according to two parameters configured by the base station: beamFailureInstanceMaxCount and beamFailureDetectionTimer. If the above parameter configuration is not reasonable enough, such as the count setting is too large or the timer setting is too long, it may cause the BFR process to start too late, and the phenomenon that the UE cannot transmit data through the beam for a long time; on the contrary, if the count setting is too small or Setting the timer too short may cause the UE to frequently perform unnecessary BFR procedures, increase unnecessary signaling overhead between the UE and the base station, and increase the power consumption of the UE.

For BFR, there may be a big gap between the time when the base station configures the BFR related parameters for the UE and the actual beam failure of the UE. For example, the beam quality in the candidate beam list configured by the base station for the UE is relatively poor, which cannot reach the UE initiation. BFR quality requirements; or, the quality threshold of the synchronization signal block (SSB) or channel state information reference signal (CSI-RS) configured by the base station for the UE is too low, causing the UE to initiate a non-contention-based random access process to try Completed the BFR process but did not succeed, but backed off to the contention-based random access process, which not only prolongs the BFR time, but also affects the uplink and downlink data transmission of the UE, and also wastes the dedicated random reserved by the network side for the UE Access resources, such as preamble code.

In order to solve at least one of the above problems, the embodiment of the present disclosure considers that the terminal records the above information and reports it to the network, which can help the network side optimize the configuration of corresponding counters, timers and other parameters and quality thresholds, and configure the terminal appropriately Can avoid unnecessary signaling overhead and waste of resources.

Referring to FIG. 3, the information sending method provided by the embodiment of the present disclosure, when applied to the terminal side, includes:

Step 31: The terminal records beam related information.

Here, the beam related information may include one or more of the following record items:

a) When the BFD timer expires, the count value of the number of beam failure instance indications.

The BFD timer expires, that is, the timer value reaches the preset timeout value. At this time, if the number of beam failure instance indications still does not reach the preset number of beamFailureInstanceMaxCount, the terminal will record the beam failure The actual count value of the number of instances indicated.

b) When BFD is detected, the timing value of the BFD timer.

Here, if before the expiration of the BFD timer, the number of beam failure instance indications has reached the preset threshold beamFailureInstanceMaxCount of the number of beam failure instance indications, and it is judged that BFD is detected at this time, the terminal will record the BFD timer when BFD occurs The actual timing value.

In NR (New Radio), the terminal can monitor the beam signal. When the monitored beam signal does not meet the requirements, the terminal physical layer will send the beam failure instance indication to the terminal medium access control layer. It is recorded as a beam failure instance indication. When the count value of the number of beam failure instance indications for beam failure is greater than or equal to the above-mentioned preset number threshold beamFailureInstanceMaxCount, it is determined that BFD has occurred, and the beam failure recovery process will be triggered at this time, and the terminal will initiate a random During the access process, the random access initiated can be non-competitive random access (CFRA, contention free random access) or competitive random access (CBRA, contention based random access).

c) When BFD is detected or a beam failure recovery process is initiated, the ID and/or number of beams that meet the first preset quality condition in the preset candidate beam list obtained by the terminal measurement.

d) When BFD is detected or a beam failure recovery process is initiated, the ID and/or number of beams that do not meet the first preset quality condition in the preset candidate beam list obtained by the terminal measurement.

e) When BFD is detected or a beam failure recovery process is initiated, the ID and/or number of beams that meet the first preset quality condition out of the preset candidate beam list obtained by the terminal measurement.

f) Information about failed beams that the terminal has tried but failed in the beam failure recovery process, where the failed beam information includes at least one of the following information: beam ID, beam quality, number of access attempts on the beam, and failure The total number of beams.

g) The qualified beam information of the source cell and/or the target cell where the terminal is handed over, the qualified beam information includes at least one of the following information: the ID of the qualified beam, the number of the qualified beam, the qualified beam IDs of the reference beams participating in the cell quality calculation and the number of the reference beams; wherein the qualified beams are beams that meet the second preset quality condition.

Step 32: The terminal reports the recorded beam related information to the network.

Through the above steps, the terminal can record and report the above-mentioned beam-related information, so that after receiving the above-mentioned beam-related information, the network device can use the information to optimize the terminal's beam failure detection and/or beam failure recovery related parameter configuration, for example, adjust The preset number threshold beamFailureInstanceMaxCount of the number of beam failure instance indications, the timeout value of the BFD timer, the candidate beam list, the first preset quality condition that the beam initiating BFR needs to meet, and the dedicated random access resource of the candidate beam list, etc., Therefore, unnecessary signaling overhead and resource waste caused by inappropriate parameter configuration can be avoided.

In the above step 32, there are many ways for the terminal to report the recorded beam related information to the network, for example:

1) The terminal may report the recorded beam related information to the network according to the first request message for acquiring the beam related information sent by the network.

In this way 1, the terminal sends the beam related information to the network according to the request of the network.

2) The terminal independently reports the recorded beam related information to the network;

In this way 2, the terminal can independently send the beam related information to the network. For example, the terminal periodically reports the beam-related information, or the terminal may also report it irregularly, for example, when the recorded beam-related information meets a preset condition, such as when the amount of recorded data reaches a certain value, it is reported. And so on, the embodiments of the present disclosure do not specifically limit this.

3) The terminal reports the log information of the beam-related information to the network, and after receiving the second request message sent by the network according to the log information to obtain the beam-related information, reports the recorded beam-related information to the network information.

In this way 3, the terminal reports log information to the network, and the log information can carry indication information of the beam-related information currently recorded by the terminal, such as the amount of data of the beam-related information recorded or the recording period involved. The log information determines whether the terminal is required to report.

In addition, in order to facilitate configuration or adjustment of the record items included in the beam-related information that the terminal needs to record, before step 31 above, the terminal may also receive configuration information of the record items included in the beam-related information sent by the network. , According to the configuration information, determine the record items that the terminal needs to record, and then record in step 31. Alternatively, the terminal determines the record items it needs to record according to the record items pre-configured by itself, and records in step 31.

The above describes the processing flow of recording and reporting beam related information on the terminal side in the embodiments of the present disclosure. The processing at the network device will be described below.

4, an embodiment of the present disclosure provides an information receiving method, which can be applied to a network device. The network device can be a physical device or a module in the physical device. Specifically, the network device can be a network manager, Trace Collection Entity (TCE, Trace Collection Entity) or base station, etc. As shown in Figure 4, the information receiving method includes:

Step 41: The network device receives the beam related information recorded by the terminal and reported by the terminal.

Similarly, the beam related information shown includes at least one of the following record items:

b) When BFD is detected, the timing value of the BFD timer.

In the foregoing step 41, the network device sends a first request message for acquiring the beam related information to the terminal, and receives the beam related information reported by the terminal according to the first request message; or, The network device receives the beam-related information independently reported by the terminal; or, the network device receives the log information of the beam-related information reported by the terminal, and sends a message to the terminal according to the log information. The second request message for the beam-related information, and receive the beam-related information reported by the terminal according to the second request message.

Through the above steps, the network device of the embodiment of the present disclosure can obtain the beam-related information, thereby optimizing the counters, timers and other parameters related to beam failure detection and/or beam failure recovery, and the configuration of beam quality thresholds, And configure appropriate candidate beams, etc., so as to avoid unnecessary signaling overhead and resource waste caused by improper parameter configuration.

Specifically, after step 41, the network device may adjust configuration parameters related to beam failure detection BFD and/or beam failure recovery BFR according to the beam-related information reported by the terminal, and the configuration parameters include the following At least one of the parameters:

The timeout value of the BFD timer;

List of candidate beams;

Dedicated random access resource for candidate beam list.

Through the above steps, the embodiments of the present disclosure can optimize configuration parameters related to beam failure detection and/or beam failure recovery based on the beam-related information reported by the terminal, thereby avoiding unnecessary signaling caused by improper parameter configuration Overhead and resource waste, and improve the terminal's uplink and downlink data transmission efficiency.

In addition, in order to facilitate the control of the record items that the terminal needs to record, before the above step 41, the network device may also send configuration information of the record items included in the beam-related information to the terminal, where the configuration information is used to instruct the terminal Record items to be recorded.
