Description

Beam failure processing method, secondary base station failure processing method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a beam failure processing method, a secondary base station failure processing method, and a terminal.

Background

In future 5G (5Generation, fifth Generation) mobile communication systems, high frequency communication and large-scale antenna technology will be introduced to achieve the target of downlink transmission rate of 20 megabits per second (Gbps) and uplink transmission rate of 10 Gbps. In particular, high frequency communication can provide wider system bandwidth, and the antenna size can be smaller, which is more beneficial to the deployment of large-scale antennas in base stations and terminals. However, high frequency communication has the disadvantages of large path loss, easy interference, weak link, etc., and large-scale antenna technology can provide large antenna gain, so that the combination of high frequency communication and large-scale antenna is a necessary trend of future 5G mobile communication systems.

However, the problem of link vulnerability in high frequency communications still exists. In the prior art, when a signal is blocked in high-frequency communication, a beam failure recovery mechanism may be used to switch a beam, so as to switch a communication link from a poor beam to a candidate beam with a good communication link. The prior art provides a terminal beam failure recovery mechanism, but does not provide a processing mechanism for how to handle some defined uplink transmission behaviors when the terminal detects a beam failure.

Fig. 1 is a schematic diagram of a system architecture according to an embodiment of the present invention, and as shown in fig. 1, the system includes: network side equipment and a terminal.

The network side device may be a Base Transceiver Station (BTS) in Global System for mobile communications (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (evolved Node B, eNB or eNodeB) in LTE, a relay Station or Access point, or a Base Station in a future 5G network, and the like, which is not limited herein.

A terminal may be a wireless terminal, which may be a device that provides voice and/or other traffic data connectivity to a user, a handheld device having wireless connection capability, or other processing device connected to a wireless modem. A wireless terminal, which may be a mobile terminal such as a mobile telephone (or "cellular" telephone) and a computer having a mobile terminal, e.g., a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more core networks via a Radio Access Network (RAN), and may exchange language and/or data with the RAN. For example, devices such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs) are used. A wireless Terminal may also be referred to as a system, a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile), a Remote Station (Remote Station), a Remote Terminal (Remote Terminal), an access Terminal (access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), and a User Equipment (User device User Equipment), which are not limited herein.

In the scenario shown in fig. 1, signal transmission is implemented between the network side device and the terminal through an antenna beam. The network side device and the terminal may both include a plurality of beams, and it is assumed that the network side device includes N beams and the terminal includes M beams, where N, M is a positive integer, and N and M may be the same or different.

As shown in fig. 2, the method for processing beam failure in the embodiment of the present invention specifically includes the following steps:

step 21: and receiving a downlink reference beam or a downlink reference signal sent by the network side equipment.

The downlink reference beam or the downlink reference signal is a reference beam or a reference signal corresponding to a downlink control channel, and/or the downlink reference beam or the downlink reference signal is a reference beam or a reference signal corresponding to a downlink service. The reference for the path loss estimation in the uplink Timing Advance (TA) configuration information and the power control parameter information of the terminal transmission beam is based on the downlink signal, that is, the downlink beam or the downlink signal needs to be measured as the reference for the uplink transmission configuration parameter, and then the uplink parameter is adjusted according to the uplink transmission configuration parameter.

Step 22: and if the downlink reference wave beam or the downlink reference signal fails to be received, adjusting an uplink transmission mode corresponding to the downlink reference wave beam or the downlink reference signal according to a preset wave beam processing mode.

In the process of signal transmission between the terminal and the network side device, a problem of connection failure may occur in a currently used beam, so that a signal cannot be normally transmitted. The terminal may perform measurement of the downlink reference beam or downlink reference signal to determine whether the reference beam is connected normally. Specifically, the signal transmission quality may be measured according to a reference beam or a reference signal sent by the network side, and for a beam currently in use, if the obtained signal transmission quality is lower than a preset threshold, the beam is considered to have failed to be received. When the downlink reference beam or the downlink reference signal is failed to be received, the uplink transmission mode corresponding to the downlink reference beam or the downlink reference signal is adjusted according to the preset beam processing mode, which can be specifically realized by referring to the following modes.

The first method is as follows:

step 22 comprises: and if the downlink reference beam or the downlink reference signal fails to be received, stopping sending the uplink signal corresponding to the downlink reference beam or the downlink reference signal to the network side equipment.

The beam pair between the terminal and the network side device has two situations: the network side equipment transmitting beam and the terminal receiving beam are paired, and/or the terminal transmitting beam and the network side equipment receiving beam are paired. When the terminal configures a transmission beam, an uplink transmission beam of the terminal may have a corresponding downlink beam as a reference beam or a corresponding downlink reference signal as a reference signal. The downlink reference beam or the downlink reference signal is used for TA configuration of the uplink transmission beam and downlink reference of the power control parameter, where the downlink reference beam or the downlink reference signal may be the same or different for the TA and the power control parameter. Further, the reference relationship between the uplink transmission beam and the downlink beam or the downlink signal of the terminal may be dynamically configured by the base station, or may be default by the base station.

Specifically, the stopping of sending the uplink signal corresponding to the downlink reference beam or the downlink reference signal to the network side device includes at least one of the following:

stopping sending Sounding Reference Signals (SRS) corresponding to the downlink Reference beams or the downlink Reference signals to the network side device;

stopping sending Channel Quality indication information (CQI) corresponding to the downlink reference beam or the downlink reference signal to the network side device;

stopping sending Semi-Persistent Scheduling (SPS) information corresponding to the downlink reference beam or the downlink reference signal to the network side device; and the number of the first and second groups,

and stopping sending uplink scheduling-free grant information (UL grant-free) corresponding to the downlink reference beam or the downlink reference signal to the network side equipment.

Further, when the terminal further monitors that the downlink reference beam or the downlink reference signal corresponding to the uplink transmission has recovered to be normal, the terminal may resume normal transmission of the uplink transmission. When the terminal detects that the downlink reference wave beam or the downlink reference signal is failed to be received, the terminal stops sending corresponding uplink transmission, and unnecessary transmission power consumption of the terminal can be reduced.

The second method comprises the following steps:

step 22 comprises: and if the downlink reference beam or the downlink reference signal fails to be received, releasing the transmission resource of the uplink transmission corresponding to the downlink reference beam or the downlink reference signal.

The method refers to listening to the transmission of the corresponding uplink transmission and releasing the transmission resource corresponding to the uplink transmission when the terminal detects that the downlink reference beam or the downlink reference signal is failed to be received, and is specifically realized by notifying a radio resource control RRC layer of the terminal to release the corresponding resource, and can also be understood as releasing the uplink beam corresponding to the downlink reference beam or the downlink reference signal. When the terminal detects that the downlink reference wave beam or the downlink reference signal fails to be received, the terminal stops sending corresponding uplink transmission, and unnecessary transmission power consumption of the terminal can be reduced. In addition, the terminal further releases the transmission resources related to the uplink transmission, so that the network transmission resource overhead can be saved, and the transmission resource utilization rate is improved.

Specifically, the releasing of the transmission resource of the uplink transmission corresponding to the downlink reference beam or the downlink reference signal includes at least one of the following:

emptying a hybrid automatic repeat request (HARQ) cache corresponding to uplink transmission;

informing a Radio Resource Control (RRC) to release an uplink control channel corresponding to uplink transmission;

informing a Radio Resource Control (RRC) to release transmission resources of Sounding Reference Signals (SRS) corresponding to uplink transmission; and the number of the first and second groups,

and emptying the transmission resources of the downlink allocation and the uplink authorization configuration corresponding to the uplink transmission.

Further, in order to inform the base station of whether to adopt the processing method of the first method or the processing method of the second method, before the step of releasing the transmission resource of the uplink transmission corresponding to the downlink reference beam or the downlink reference signal, the terminal further includes: and sending the indication information to the network side equipment. The indication information is used for indicating whether the terminal releases the transmission resource corresponding to the uplink transmission. Thus, when the base station does not receive the indication information, the base station determines that the terminal adopts the processing mode of the mode one, namely, the base station stops sending corresponding uplink transmission to the network side equipment; if the base station receives the indication information, the base station determines that the terminal adopts the processing mode of the mode two, namely, the terminal stops sending corresponding uplink transmission to the network side equipment and releases transmission resources corresponding to the uplink transmission.

The third method comprises the following steps:

step 22 may also include: if the downlink reference beam or the downlink reference signal fails to be received, determining a backspacing downlink reference beam or a backspacing downlink reference signal corresponding to uplink transmission according to the corresponding relation of the backspacing downlink reference beam or the backspacing downlink reference signal of the downlink reference beam or the downlink reference signal; receiving a retroversion downlink reference beam or retroversion downlink reference signal sent by network side equipment; and determining Timing Advance (TA) configuration information or power control parameter information of uplink transmission corresponding to the downlink reference beam or the downlink reference signal according to the retroversion downlink reference beam or the retroversion downlink reference signal.

In this manner, the terminal does not stop transmission of the corresponding uplink transmission but performs switching of the reference point after detecting that the downlink reference beam or the downlink reference signal is failed to be received. It is assumed that there are two base stations transmitting downlink beam 1 and downlink beam 2, respectively, while the terminal has two uplink transmission beams 3 and 4. The downlink reference beam corresponding to the uplink transmission beam 3 of the terminal is the downlink beam 1 transmitted by the base station, and the downlink reference beam corresponding to the uplink transmission beam 4 of the terminal is the downlink beam 2 transmitted by the base station. When the terminal detects that the downlink beam 1 sent by the base station fails, the downlink reference beam corresponding to the uplink sending beam 3 of the corresponding terminal can be switched to the downlink beam 2 sent by the base station, so that the UE can send uplink by taking the new reference beam as a reference.

Wherein, downlink reference beams or downlink reference signals on the same base station antenna panel (panel) are backspacing downlink reference beams or downlink reference signals;

or, downlink reference beams or downlink reference signals corresponding to different beams of the same terminal antenna panel (panel) are fallback downlink reference beams or downlink reference signals;

or, the downlink reference beams or downlink reference signals in the same beam group (beam group) are fallback downlink reference beams or downlink reference signals;

or, the downlink reference beams or downlink reference signals which are quasi co-located with all or part of the downlink reference beams or downlink reference signals which are failed to be received are the fallback downlink reference beams or downlink reference signals. For example, the downlink reference beams or downlink reference signal angles with the smallest angle difference with the downlink reference beams or downlink reference signals with failed reception are the fallback downlink reference beams or downlink reference signals.

As shown in fig. 3, the method for processing beam failure in the embodiment of the present invention specifically includes the following steps:

step 31: and receiving a downlink reference beam or a downlink reference signal sent by the network side equipment.

The downlink reference beam or the downlink reference signal is a reference beam or a reference signal corresponding to a downlink control channel, and/or the downlink reference beam or the downlink reference signal is a reference beam or a reference signal corresponding to a downlink service.

Step 32: and detecting a receiving result of the downlink reference beam or the downlink reference signal.

If the downlink reference beam or the downlink reference signal is not received within the preset time, or the received power or the received strength of the downlink reference beam or the downlink reference signal received within the preset time is lower than a preset threshold value, it is determined that the downlink reference beam or the downlink reference signal is failed to be received. Otherwise, the downlink reference beam or the downlink reference signal is successfully received.

Step 33: and if the downlink reference wave beam or the downlink reference signal fails to be received, adjusting an uplink transmission mode corresponding to the downlink reference wave beam or the downlink reference signal according to a preset wave beam processing mode.

Specifically, in the process of signal transmission between the terminal and the network side device, a problem that a connection failure may occur in a currently used beam may result in that a signal cannot be normally transmitted, and when a downlink reference beam or a downlink reference signal fails to be received, adjusting an uplink transmission mode corresponding to the downlink reference beam or the downlink reference signal according to a preset beam processing mode may be specifically implemented by referring to the above listed modes, and therefore details are not repeated herein.

Step 34: and if the downlink reference beam or the downlink reference signal is successfully received, determining Timing Advance (TA) configuration information or power control parameter information of uplink transmission corresponding to the downlink reference beam or the downlink reference signal according to the downlink reference beam or the downlink reference signal.

In the beam failure processing method of the embodiment of the invention, when a terminal fails to receive a downlink reference beam or a downlink reference signal sent by a network side device, uplink transmission corresponding to the downlink reference beam or the downlink reference signal is processed according to a preset beam processing mode, and after the terminal fails to detect the beam, a processing mode of how to process a defined uplink sending behavior is given. Specifically, if the terminal detects that the downlink reference beam or the downlink reference signal is failed to be received, the terminal stops sending corresponding uplink transmission, so that unnecessary transmission power consumption of the terminal can be reduced; if the terminal detects that the downlink reference beam or the downlink reference signal is failed to be received, the reference point of the uplink transmission is switched so as to ensure the reliability of the uplink transmission.

Specifically, if the terminal detects that the downlink reference beam or the downlink reference signal is failed to be received, the terminal stops sending corresponding uplink transmission, so that unnecessary transmission power consumption of the terminal can be reduced; if the terminal detects that the downlink reference beam or the downlink reference signal is failed to be received, the reference point of the uplink transmission is switched so as to ensure the reliability of the uplink transmission.

In a 5G mobile communication system, a terminal may implement Dual Connectivity (DC) with a network side device (e.g., a base station), that is, the same terminal may establish a connection with a main base station (MgNB, Master nodeb) and a Secondary base station (SgNB, Secondary nodeb), but the SgNB may have a connection failure due to a poor network condition. However, in the prior art, there is no way how the terminal handles the secondary cell group in the SgNB connection failure scenario.

In order to solve the above problem, another embodiment of the present invention further provides a method for processing failure of a secondary base station, which is applied to a terminal, and as shown in fig. 7, the method specifically includes the following steps:

step 71: and if the failure of the secondary base station of the current cell is detected, determining the failure type of the secondary base station failure.

Wherein the failure types of the secondary base station failure include: at least one of a failure of radio link of the secondary base station, a failure of handover of the secondary base station, a failure of uplink transmission time difference (for example, uplink transmission time difference of uplink DC transmission of two carriers) of the terminal in two carriers or cells exceeding a maximum value of terminal capability, a failure of configuration of the secondary base station, and a failure of Radio Resource Control (RRC) integrity check of the secondary base station.

Step 72: and determining the suspension mode of the wireless bearer of the group data of the secondary cell according to the failure type.

Different failure types of SgNB failure are listed above, and the failure types are different, and the suspension modes of the Secondary Cell Group (SCG) Data Radio Bearer (DRB) are different.

Specifically, if the failure type of the Secondary base station failure is a Secondary base station Radio link failure, or the uplink transmission time difference of the terminal in two carriers or cells exceeds the maximum terminal capability value, the SCGDRB of all Secondary Cell Group Data Radio bearers is suspended, the SCG transmission part in the SCG split DRB (Secondary Cell Group Data Radio Bearer) is suspended, and the SCG transmission part in the MCG split DRB (Master Cell Group split Data Radio Bearer) is suspended. That is, if the failure type of the secondary base station failure is the secondary base station radio link failure, or the uplink transmission time difference between two carriers or cells of the terminal exceeds the maximum terminal capability value, it is sufficient for the terminal to suspend the SCG transmission part in the SCG split DRB.

If the failure type of the secondary base station failure is the switching failure of the secondary base station, the configuration failure of the secondary base station or the failure of the radio resource control integrity check of the secondary base station, suspending all the secondary cell group data radio bearers SCG DRB, suspending SCG sending parts in all the secondary cell group component data radio bearers SCG split DRB, suspending MCG sending parts in all the secondary cell group component data radio bearers SCG split DRB and suspending all the primary cell group component data radio bearers MCG split DRB. That is, if the failure type of the secondary base station failure is the secondary base station handover failure, the secondary base station configuration failure, or the radio resource control integrity check failure of the secondary base station, the terminal needs to suspend the SCG transmission part in the SCGsplit DRB for the SCG split DRB, and the MCG transmission part in the SCG split DRB should also be suspended.

Wherein, MCG DRB refers to a bearer only transported on MgNB, SCG DRB refers to a bearer only transported on SgNB, and MCG split DRB and SCG split DRB refer to that some transmissions can be on MgNB and some transmissions can be on SgNB. Wherein, the PDCP (Packet Data Convergence Protocol) entity of the MCG split DRB is on MgNB, and the PDCP entity of the SCG split DRB is on SgNB.

In the method for processing failure of the secondary base station in the embodiment of the invention, when the terminal detects that the secondary base station fails, the suspension mode of the corresponding secondary cell group data radio bearer is determined according to the failure type of the secondary base station failure, namely, when the secondary base station fails, the suspension mode of the corresponding secondary cell group data radio bearer is given, and the corresponding suspension mode is determined according to the failure type of the secondary base station failure, so that unnecessary bearer transmission of the terminal when the secondary base station fails is avoided, the power consumption of the terminal is reduced to a certain extent, in addition, the wrong bearer transmission of the terminal can be avoided, and unnecessary interference to other terminals is avoided.
