Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic diagram of a system architecture according to an embodiment of the present disclosure, and as shown in fig. 1, the system includes: network side device 01 and terminal 02.
The network side device 01 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 are not limited herein.
Terminal 02 can be a wireless terminal, which can 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, or can be a wired terminal. 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 01 and the terminal 02 through an antenna beam. Both the network side device 01 and the terminal 02 may include a plurality of beams, and for example, in fig. 1, it is assumed that the network side device 01 includes N beams and the terminal 02 includes M beams, where N, M are integers greater than 1. N and M may be the same or different, and the application is not limited.
It should be noted that, a situation that a connection failure may occur in a beam for performing signal transmission between the terminal and the network side device, and if there is no available candidate beam when starting beam recovery due to the connection failure, a link failure may be reported to the core network side by the network side device. Once link failure is reported to the core network, the core network may participate in the following process, that is, the core network device may first instruct the network side device to recover the link, and then the network side device and the terminal negotiate to recover the link, so that a large recovery delay may be generated. The method provided by the application solves the problem of beam connection failure on the premise of not reporting the core network as much as possible.
Fig. 2 is a schematic flow chart of a beam failure recovery processing method according to an embodiment of the present application, and as shown in fig. 2, this embodiment is mainly implemented from a terminal perspective: if there is no technical improvement of available candidate beams after the terminal sends the beam failure recovery request, the method comprises the following steps:
s201, the terminal sends a beam failure recovery request to the network side equipment.
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 beam measurements to determine whether the beam connection is normal. Specifically, the signal transmission quality may be measured according to a reference signal sent by the network side, or the reference signal may be sent to the network side device to obtain the signal transmission quality measured by the network side device. For the beam currently in use, if the obtained signal transmission quality is lower than the preset threshold, the beam is considered to be failed. Similarly, if the measured signal transmission quality of one or more beams is greater than or equal to a predetermined threshold, the beam may be used as a candidate beam.
After detecting the beam failure, the terminal sends a beam failure recovery request to the network side device, so as to negotiate with the network side device to switch the candidate beam for signal transmission.
S202, if the terminal determines that no available candidate beam exists, the terminal performs candidate beam measurement within a first preset time.
Optionally, if the terminal determines that there is a candidate beam after measuring the beam failure, the terminal may notify the network side device of the fact that the candidate beam identifier is carried in the beam failure recovery request, so that the network side device switches the candidate beam to transmit the signal.
If the terminal determines that no available candidate beam exists after determining that the beam fails, the terminal performs candidate beam measurement within a certain time, that is, whether a beam with a signal transmission quality meeting a preset threshold is measured to be a candidate beam.
It should be noted that the absence of available candidate beams may include at least two layers: (1) there is no candidate beam currently, for example, the signal transmission quality calculated by the terminal according to the reference signal does not meet the preset threshold. (2) And the terminal acquires the candidate wave beam through measurement, and the network side equipment replies unavailable after reporting to the network side equipment. Optionally, it may be found by the network side device that the candidate beam is already occupied, for example, for transmitting other signals, and the application is not particularly limited.
In this embodiment, after the terminal sends the beam failure recovery request to the network side device, if it is determined that there is no available candidate beam, the terminal performs candidate beam measurement within a first preset time. That is, after the terminal measures the beam failure, if there is no available candidate beam, the terminal does not report the link failure, but waits for a period of time, and performs the candidate beam measurement in the period of time, so as to ensure the physical layer interactive between the terminal and the network side to recover the beam as much as possible, and reduce unnecessary recovery delay.
Fig. 3 is a schematic flow chart of a beam failure recovery processing method according to another embodiment of the present application, and as shown in fig. 3, the difference between the embodiment and the embodiment shown in fig. 2 is that the embodiment is mainly implemented from the perspective of a network side device: if there is no technical improvement of available candidate beams after receiving a beam failure recovery request sent by a terminal, the method comprises the following steps:
s301, the network side equipment receives a beam failure recovery request sent by the terminal.
Similar to the foregoing S201, after detecting the beam failure, the terminal may send a beam failure recovery request to the network side device.
S302, the network side equipment determines that no available candidate beam exists.
Alternatively, one possibility is that there is currently no candidate beam. Specifically, the network side device may determine that no candidate beam is reported by the terminal within a third preset time before the beam failure recovery request is received, and the beam failure recovery request does not carry the candidate beam, so that the network side device considers that there is no candidate beam. Another possibility is that the network side device receives the candidate beam reported by the terminal within the third preset time, or the candidate beam is carried in the beam failure recovery request, but the network side device finds that the candidate beam is currently unavailable.
Optionally, if the network side device finds that the candidate beam is not available, the terminal is notified that the candidate beam is not available.
S303, the network side device does not receive the beam report information including the candidate beam sent by the terminal within the second preset time, or receives the first radio link failure message sent by the terminal within the second preset time, and the network side device sends the second radio link failure message to the core network device.
After receiving the beam failure recovery request, the network side device waits for a period of time if it is determined that there is no available candidate beam, the terminal can perform candidate beam measurement within the period of time, and if the terminal measures for a period of time or does not find a suitable candidate beam, the terminal sends a first radio link failure message to the network side device, that is, the network side device informs the network side device of the link failure, and then the network side device sends a second radio link failure message to the core network device to report the core network device of the link failure.
It is also possible that after the network side device waits for a period of time, the terminal does not send the first radio link failure message, but does not report the candidate beam, that is, there is still no available candidate beam, and then the network side device sends the second radio link failure message to the core network device to report the core network device link failure.
In this embodiment, after receiving a beam failure recovery request sent by a terminal, a network side device determines that there is no available candidate beam, and waits for a second preset time, and does not report a link failure to a core network device in this time unless the network side device does not receive beam report information containing the candidate beam sent by the terminal within the second preset time or receives a first radio link failure message sent by the terminal within the second preset time, and then sends a second radio link failure message to the core network device. The physical layer of the interaction between the terminal and the network side can be ensured to recover the wave beam as much as possible, and unnecessary recovery time delay is reduced.
It should be noted that, in the above different embodiments, the second preset time and the first preset time may refer to the same preset time or different preset times, and specific examples are described below.
The candidate beams according to the above embodiments may refer to: at least 1 transmitting beam of the terminal and at least 1 receiving beam paired with the transmitting beam in the network side equipment; it can also refer to at least 1 receiving beam of the terminal and at least 1 transmitting beam paired with the receiving beam by the network side device; both of these cases may be included.
In one implementation scenario: if the candidate beams include at least 1 transmit beam of the terminal and at least 1 receive beam paired with the transmit beam in the network side device, the terminal may respectively transmit a reference signal using each transmit beam in a preset range of the terminal in the process of measuring the candidate beams. Accordingly, each receiving beam within the preset range of the network side device receives the reference signals sent by all the transmitting beams. One or more pairs of candidate beams with signal transmission quality meeting a preset threshold can be further determined. Specifically, if only one pair of candidate beams is needed, a pair of candidate beams with the best signal transmission quality, that is, the transmitting antenna with the best transmission quality and the receiving antenna with the best signal transmission from the transmitting antenna, may be selected from the beams satisfying the preset threshold, and is not particularly limited herein.
Similarly, in another implementation scenario, if the candidate beams include at least 1 receiving beam of the terminal and at least 1 transmitting beam paired with the receiving beam by the network-side device, the network-side device transmits the reference signal using each transmitting antenna within the preset range, and the terminal receives the reference signal transmitted by all transmitting antennas using each receiving antenna within the preset range. Further determining one or more pairs of candidate beams with signal transmission quality meeting a preset threshold
It should be noted that the preset range of beams may refer to one or more beams within the device beam management range, and these beams may be some or all of the beams of the device. Assuming that the terminal has 8 transmitting and receiving beams, and after 2 transmitting beams for transmitting data fail, the terminal measures and selects candidate beams among 4 transmitting beams in a preset range, and of course, without being limited thereto, the candidate beams may be measured and selected among all beams except the failed beams.
For the case that the terminal determines that the beam fails and has no available candidate beam, the scheme of the application waits for a period of time instead of directly reporting the link failure to the core network device, and in the period of time, the terminal can measure and search for the candidate beam to find the candidate beam in the prolonged period of time as far as possible so as to complete beam recovery. This time may be monitored by the terminal, such as described in the embodiment of fig. 2; or may be monitored by a network-side device as described in the embodiment shown in fig. 3; or may be monitored by both the terminal and the network side device.
In addition, after the terminal sends the beam failure recovery request to the network side device, the network side device replies a beam failure recovery response. The terminal may also perform candidate beam measurement for a period of time, with the time when the beam failure recovery response is received as a starting point. The candidate beam measurement may be performed for a period of time with the time when the beam failure recovery request is issued as a starting point. The period of time may be the first predetermined time or the second predetermined time.
Hereinafter, different implementations of candidate beam measurement timing, duration control, and the like after a beam failure will be described separately.
Alternatively, the first preset time may be preset in the terminal. The terminal may also receive configuration information including the first preset time, which is sent by the network side device, before performing the candidate beam measurement within the first preset time. Specifically, the configuration information including the first preset time may be sent by the network side device when the terminal accesses, or may be sent in a subsequent signal transmission process, which is not limited in this application.
In one mode, the terminal and the network side device are configured in advance with a time when the terminal sends out the beam failure recovery request as a first preset time starting point, or with a time when the terminal receives the beam failure recovery response as the first preset time starting point. The terminal may determine the length of the first preset time according to the configuration information including the first preset time. That is, the network side device indicates the length of the first preset time in the configuration information containing the first preset time.
In another mode, the network side device indicates the length and the starting time of the first preset time in the configuration information containing the first preset time. For example: the configuration information including the first preset time indicates the length of the first preset time, and the terminal takes the moment of sending the beam failure recovery request as the starting point of the first preset time. Or, the configuration information including the first preset time indicates the length of the first preset time, and the terminal takes the time when the beam failure recovery response is received as the starting point of the first preset time.
Alternatively, the first preset time may be pre-configured in the terminal, and no special configuration information is transmitted.
In one embodiment, the first preset time is timing time information of a first timer. I.e. the first preset time is realized by the first timer.
Correspondingly, the terminal receives the timing time information of the first timer sent by the network side equipment before the candidate beam measurement is carried out within the first preset time. Similarly to the above-described embodiment, the network-side device may indicate the timing length of the first timer, or indicate both the timing length of the first timer and the start time of the timing time of the first timer, depending on the specific situation.
Specifically, the terminal starts a first timer and performs candidate beam measurement within a timing time of the first timer.
Based on the foregoing embodiment, the network side device may not separately set the second preset time, and then the network side device may perform waiting without reporting the second radio link failure message until the terminal reports the candidate beam or sends the first radio link failure message.
Fig. 4 is a schematic flow chart of a beam failure recovery processing method according to another embodiment of the present application, and fig. 4 illustrates a beam failure recovery processing flow by taking an example of a terminal starting a first timer. As shown in fig. 4, the method includes:
s401, the terminal determines that the current beam connection fails.
S402, the terminal sends a beam failure recovery request to the network side equipment.
And S403, the terminal receives the beam failure recovery response sent by the network side equipment.
S404, the terminal determines that no available candidate beam exists.
S405, the terminal starts a first timer and performs candidate beam measurement within the timing time of the first timer.
It should be noted that the terminal itself knows that there is no candidate beam, and it may not take time to determine that there is no available candidate beam, that is, the terminal may start the first timer at the time when the beam failure recovery response is received.
If the terminal does not measure the candidate beam within the first preset time, S406 to S407 are performed. If the terminal measures the candidate beam within the first preset time, S408 to S409 are performed.
S406, the terminal sends a first radio link failure message to the network side equipment.
S407, the network side device sends a second radio link failure message to the core network device.
S408, the terminal sends the beam reporting information containing the candidate beams to the network side equipment.
S409, after determining that the candidate beam is available, the network side device enables the candidate beam and the terminal to transmit signals.
In this embodiment, after receiving the beam failure recovery response, if it is determined that there is no available candidate beam, the terminal starts the first timer, and performs candidate beam measurement within the timing time of the first timer, that is, the link failure is not reported temporarily, but the candidate beam measurement is continued for a certain time, so as to increase the chance of acquiring the candidate beam, thereby ensuring that the physical layer recovery beam interacted between the terminal and the network side is ensured as much as possible, and reducing unnecessary recovery delay.
On the basis of the embodiment of fig. 3, the network side device may send configuration information including the second preset time to the terminal.
