Description

Information sending method, information receiving method, terminal and network equipment

Technical Field

The invention relates to the technical field of mobile communication, in particular to an information sending method, an information receiving method, a terminal and network equipment.

Background

A 5G new air interface (NR) system may operate in a high frequency band of 6-100GHz, and coverage of a common control channel and even a data channel is ensured by introducing multi-beam deployment. The quality of the high-frequency Beam changes rapidly and is easily blocked, a Beam Failure (Beam Failure) condition may occur, and when a terminal (e.g., a UE, hereinafter, the UE is taken as an example) performs a Beam Failure Detection (BFD), a Beam Failure Recovery (BFR) process may be initiated.

Fig. 1 is a diagram illustrating an interaction procedure performed by the UE and the base station in the BFD procedure, where the base station configures a BFD and BFR related parameter for the UE, such as a time length for detecting the BFD, i.e., a beamfailure detetectiontimer, which is referred to herein as a BFD timer (for convenience of description, which is also referred to herein as a timer), a maximum number of times of beam failure instance indication times, i.e., a threshold beamfailure event probability value, a quality threshold of a BFR beam (for convenience of description, which is also referred to herein as a count), a candidate beam list, a dedicated random access resource, and the like. And the UE judges whether BFD occurs or not according to the two parameters, namely the timer and the count. When BFD occurs, UE starts BFR flow, at this time UE can select wave beam whose wave beam quality can meet the quality threshold of the above-mentioned BFR wave beam from the candidate wave beam list, and utilizes the configured special random access resource to initiate BFR process on the wave beam.

Referring to fig. 2, fig. 2 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 21 and a network device 22. The terminal 21 may also be referred to as a User terminal or a User Equipment (UE), where the terminal 21 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 21 is not limited in the embodiment of the present invention. The network device 22 may be an RRH, a Base Station or a core network element, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, an RRH, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that in the embodiment of the present invention only uses the Base Station in the NR system as an example, but does not limit the specific type of base station.

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

The base stations may communicate wirelessly with the terminals 21 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 21 to network device 22) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 22 to terminal 21). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission. Downlink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be made using licensed frequency bands, unlicensed frequency bands, or both.

As described in the background, for BFD, since the terminal (e.g., UE) is configured with two parameters according to the base station: the beamf ailurelnstanceinmaxcount and beamf ailuredetectiontimer are used to determine whether BFD is generated. If the parameter configuration is not reasonable enough, if the count setting is too large or the timer setting is too long, the flow of the BFR may be started too late, and the UE may not transmit data through the beam as early as possible; on the contrary, if the count setting is too small or the timer setting is too short, the UE may frequently perform an unnecessary BFR procedure, which increases unnecessary signaling overhead between the UE and the base station, and also increases power consumption of the UE.

For the BFR, there may be a large difference between the time for the base station to configure the BFR related parameters for the UE and the actual condition of the beamfailure of the UE, for example, the quality of beams in the candidate beam list configured for the UE by the base station is poor, and the quality requirement for the UE to initiate the BFR cannot be met; or, the quality threshold of a Synchronization Signal Block (SSB) or a channel state information reference signal (CSI-RS) configured by the base station for the UE is too low, which causes the UE to initiate a non-contention based random access procedure to try to complete a BFR procedure, but the UE does not succeed in the non-contention based random access procedure, but backs off to the contention based random access procedure, thereby prolonging the BFR time, affecting uplink and downlink data transmission of the UE, and wasting a dedicated random access resource, such as a preamble code, reserved by the network side for the UE.

In order to solve at least one of the above problems, the embodiment of the present invention considers that the terminal records the above information and reports the information to the network, which can help the network side to optimize the configuration of parameters such as a corresponding counter and a timer, and a quality threshold, and configure information such as a suitable candidate beam for the terminal, thereby avoiding unnecessary signaling overhead and resource waste.

Referring to fig. 3, the information sending method according to the embodiment of the present invention, when applied to a terminal side, includes:

in step 31, the terminal records the beam related information.

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

a) when the BFD timer expires, the beam failure instance indicates a count of the number of times.

The BFD timer expires, that is, the timing value of the timer reaches a preset timeout value, at this time, if the number of beam failure instance indications has not yet reached a preset number threshold beamfailurelnstancensionmaxcount, the terminal will record the actual count value of the number of beam failure instance indications.

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

Here, if the number of beam failure instance indications has reached the preset threshold beamfailurelnstanceinmaxcount before the BFD timer expires, and it is determined that BFD is detected, the terminal records the actual timing value of the BFD timer when BFD occurs.

In NR (New Radio, New air interface), a terminal may monitor a beam signal, and when the monitored beam signal does not satisfy a requirement, a terminal physical layer may send a beam failure instance indication (beam failure instance indication) to a terminal medium access control layer, and record the beam failure instance indication once, and when a count value of times of the beam failure instance indication for the beam failure is greater than or equal to the preset time threshold, the beam failure instance max count is determined to occur BFD, and at this time, a beam failure recovery process is triggered, and the terminal initiates a random access process, where the initiated random access may be a non-competitive random access (CFRA, contention free random access) or a competitive random access (CBRA, contention based random access).

c) And when BFD is detected or a beam failure recovery process is initiated, the terminal measures the ID and/or the number of beams meeting the first preset quality condition in a preset candidate beam list.

d) And when BFD is detected or a beam failure recovery process is initiated, the terminal measures the ID and/or the number of the beams which do not meet the first preset quality condition in the preset candidate beam list.

e) And when BFD is detected or a beam failure recovery process is initiated, the terminal measures the ID and/or the number of the beams which are outside the preset candidate beam list and meet the first preset quality condition.

f) Failed beam information that the terminal tried but failed in the beam failure recovery process, the failed beam information including at least one of the following information: a beam ID, a beam quality, a number of attempts to access on the beam, and a total number of failed beams.

g) Qualified beam information of a source cell and/or a target cell to which the terminal is handed over, wherein the qualified beam information comprises at least one of the following information: an ID of a qualified beam, a number of the qualified beams, an ID of a reference beam of the qualified beams that participates in cell quality calculation, and a number of the reference beams; wherein the qualified beam is a beam satisfying a second preset quality condition.

And step 32, the terminal reports the recorded beam related information to the network.

Through the above steps, the terminal may record and report the beam related information, so that after receiving the beam related information, the network device may optimize the configuration of the beam failure detection and/or the beam failure recovery related parameters of the terminal by using the information, for example, adjust a preset number threshold beamfailure occurrence max count of the number of times of beam failure instance indication, a timeout value of a BFD timer, a candidate beam list, a first preset quality condition that a beam initiating a BFR needs to satisfy, and dedicated random access resources of the candidate beam list, so as to avoid unnecessary signaling overhead and resource waste caused by improper parameter configuration.

In the step 32, the terminal reports the recorded beam related information to the network in various ways, for example:

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

In the method 1, the terminal transmits the beam related information to the network according to a request of the network.

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

in the method 2, the terminal may autonomously transmit the beam related information to the network. For example, the terminal may report the beam related information periodically, or the terminal may report the beam related information aperiodically, for example, report the recorded beam related information when the recorded beam related information meets a preset condition, for example, the recorded data amount reaches a certain value, and the like.

3) And the terminal reports the log information of the beam related information to the network, and reports the recorded beam related information to the network after receiving a second request message for acquiring the beam related information, which is sent by the network according to the log information.

In the mode 3, the terminal reports log (log) information to the network, where the log information may carry indication information of beam related information currently recorded by the terminal, such as data volume of the recorded beam related information or a related recording period, and the network determines whether the terminal needs to report according to the log information.

In addition, in order to facilitate configuration or adjustment of the entry included in the beam related information that needs to be recorded by the terminal, before step 31, the terminal may further receive configuration information of the entry included in the beam related information that is sent by the network, determine the entry that needs to be recorded by the terminal according to the configuration information, and then perform recording in step 31. Alternatively, the terminal determines the entry to be recorded according to the entry configured in advance and records the entry in step 31.

The processing flow of recording and reporting the beam related information at the terminal side according to the embodiment of the present invention is described above. The processing at the network device will be described below.

Referring to fig. 4, an embodiment of the present invention provides an information receiving method, which may be applied to a network device, where the network device may be an Entity device or a module in the Entity device, and specifically, the network device may be a network manager, a Trace Collection Entity (TCE), a base station, or the like. As shown in fig. 4, the information receiving method includes:

step 41, the network device receives the beam related information recorded by the terminal, which is reported by the terminal.

Similarly, the beam related information includes at least one of the following entries:

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

In step 41, the network device sends a first request message for obtaining 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 reported by the terminal autonomously; or, the network device receives log information of the beam related information reported by the terminal, sends a second request message for obtaining the beam related information to the terminal according to the log information, and receives the beam related information reported by the terminal according to the second request message.

Through the above steps, the network device according to the embodiment of the present invention may obtain the beam related information, so as to optimize parameters such as a counter and a timer related to beam failure detection and/or beam failure recovery, and configuration of a beam quality threshold, and configure a suitable candidate beam, and further avoid unnecessary signaling overhead and resource waste caused by inappropriate parameter configuration.

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

a timeout value of the BFD timer;

a list of candidate beams;

first preset quality condition that a beam initiating BFR needs to satisfy

Dedicated random access resources of the candidate beam list.

Through the steps, the embodiment of the invention can optimize the configuration parameters related to the beam failure detection and/or the beam failure recovery based on the beam related information reported by the terminal, thereby avoiding unnecessary signaling overhead and resource waste caused by improper parameter configuration and improving the uplink and downlink data transmission efficiency of the terminal.

In addition, in order to facilitate control of the entries that the terminal needs to record, before step 41, the network device may further send, to the terminal, configuration information of the entries included in the beam related information, where the configuration information is used to indicate the entries that the terminal needs to record.
