Description

Technical Field

[0001] The present invention relates to the field of mobile communication technology, and in particular to a method, device and computer-readable storage medium for processing uplink failure. Background Art

[0002] Repeaters are network nodes used to address existing network coverage issues. Compared to 5G wireless repeaters (IABs) and relay technologies, repeaters offer lower complexity and lower costs. However, this means they lack uplink power control capabilities for backhaul links. Furthermore, repeaters feature automatic level control (ALC), which ensures output power never exceeds the maximum output power. Furthermore, repeaters can only amplify multiple simultaneously received signals using a fixed gain and cannot dynamically amplify multiple signals using varying gains.

[0003] Therefore, when a repeater receives two signals simultaneously, one large and one small, it amplifies both signals based on the gain of the large signal to ensure output power is below the maximum output power. This results in a gain compression of the small signal's actual gain compared to the target gain, leading to small signal uplink failure. This issue can cause all candidate uplink beams to fail, leading to uplink failure. Summary of the Invention

[0525] When it is determined that the uplink fails, the uplink signal transmission is stopped and the instruction of the base station is waited.

[0526] The present invention is described below with reference to scenario embodiments.

[0527] like Figure 9As shown in the figure, assuming UE1 uses 256-bit Quadrature Amplitude Modulation (QAM) for uplink transmission, occupying a 10MHz bandwidth, and the uplink transmit power received by the repeater is -62dBm. UE2 uses Quadrature Phase Shift Keying (QPSK) for uplink transmission, occupying a 10MHz bandwidth, and the uplink transmit power received by the repeater is -76dBm. Assuming the maximum gain of the repeater is 100dB and the maximum allowable uplink output power is 23dBm, if UE1 and UE2 do not transmit uplink at the same time, the repeater's gain for UE1 is 23-(-62)=85dB (target gain), and the repeater's gain for UE2 is 23-(-76)=99dB (target gain). If UE1 and UE2 transmit uplink at the same time, UE2's gain needs to be reduced compared to the 99dB gain in the scenario where it transmits alone. That is, the actual gain is 85dB instead of the target 99dB, a gain reduction of 14dB. The presence of UE1 may cause UE2's uplink / beam failure. However, the downlink target gain is equal to the actual gain, meaning that even if the uplink beam / link fails, the downlink remains connected for a short period of time.

[0528] At this time, the base station instructs the terminal to try to establish an uplink by selecting a new beam and increasing the transmit power. However, in this scenario, the gains of all uplink candidate beams are affected. Even if the terminal's uplink transmit power is increased, the actual repeater output gain is limited. At this time, selecting a new beam and increasing the transmit power will only increase the base station's receiving noise floor but will not fundamentally solve the uplink reception problem. Increasing the uplink transmit power will also increase the terminal's power consumption.

[0529] Therefore, in order to solve the above problems, this embodiment proposes the following solutions:

[0530] Example 1

[0531] like Figure 7 As shown, this embodiment includes the following steps:

[0532] Step 1: The repeater reports gain change indication information B to the base station;

[0533] The information B may be RRC signaling, MAC CE signaling or DCI indication;

[0534] This information B is used to assist the base station in determining whether the current repeater amplifies one or more terminal signals according to the target gain, thereby assisting the base station in determining whether the uplink / beam fails and the reason for the failure.

[0535] Here, the method for the repeater to distinguish signals from multiple terminals and the power of the signals received from the multiple terminals includes:

[0536] The base station informs the repeater of the DMRS patterns of the multiple terminals it serves. The repeater distinguishes different terminals by measuring the DMRS symbol power and RSSI and evaluates the received signal power of each of the multiple terminals; or

[0537] The base station informs the repeater of the SRS reference symbol configuration of multiple terminals it serves. The repeater distinguishes different terminals by measuring the SRS symbol power and RSSI and evaluates the signal power received from each of the multiple terminals.

[0538] The information B includes one or more of the indication bit, the total signal power received by the repeater, the actual amplification gain of the repeater, the difference between the actual amplification gain of the repeater and the target gain, and the difference between the maximum signal power and the minimum signal power of all signals received by the repeater (the gain difference can be indicated separately for each terminal).

[0539] If the repeater cannot distinguish whether the received signal comes from multiple terminals, it only needs to report one or more of the total power of the signal received by the repeater and the actual amplification gain information of the repeater.

[0540] The indication bit is used to indicate whether the repeater amplifies all terminal signals according to the target gain. For example, if the amplification gain of a terminal is less than the target gain, the indication bit is set to 1, otherwise it is set to 0.

[0541] The triggering conditions for the repeater to report the gain change indication information B include one or more of the following:

[0542] If the base station determines that there is a problem with the terminal's uplink / beam, it will instruct the repeater to report it;

[0543] The repeater determines that a difference between a target gain and an actual amplification gain for at least one terminal is greater than a threshold A;

[0544] Periodically triggered or semi-continuously scheduled by the base station.

[0545] Step 2: After receiving the repeater gain compression information B, the base station sends gain compression information C to the UE;

[0546] The gain compression information C includes the indication bit and the time-frequency position of the UE feedback information on whether the synchronization is lost. The C information is optional information, and the base station may also go directly to step 4 without sending C. Figure 8 shown.

[0547] The indication bit is used to indicate whether the repeater amplifies all terminal signals according to the target gain. For example, if the amplification gain of a terminal is less than the target gain, the indication bit is set to 1, otherwise it is set to 0.

[0548] The time-frequency position of the UE's feedback of the information on whether the synchronization is lost indicates that the terminal sends an uplink signal at the corresponding time-frequency position, and the position may be a subset of the SRS reference symbol or DMRS reference symbol configuration.

[0549] Step 3: When the terminal receives information C, it sends feedback information (uplink desynchronization information) at the feedback time-frequency position indicated by C to assist the network in determining the uplink connection status of the corresponding terminal; if there is no time-frequency position indicating whether the feedback is desynchronized in C, the terminal sends PUSCH and PUCCH normally.

[0550] Step 4: If the base station receives feedback from the terminal, it considers the terminal to be in a connected state. Alternatively, the base station tests the DMRS reference symbol power or PUCCH power within a certain time window. If the power is greater than a certain threshold, the terminal is considered to be in a connected state. Otherwise, the terminal is considered to have an uplink beam failure. The base station notifies the uplink / beam failure UE to stop beam transmission or switch to another suitable cell or schedule the failed terminal to transmit uplink at a different time from the terminal that caused the gain compression.

[0551] Example 2

[0552] This embodiment omits and replaces steps 2, 3, and 4 in embodiment 1. Figure 8 Said method comprises:

[0553] Step 1: The repeater reports gain change indication information B to the base station;

[0554] This step is the same as that in Example 1 and will not be described in detail here.

[0555] Step 2: After receiving information B, the base station determines the cause of the uplink failure of the current terminal based on the UE scheduling information, the UE received signal power, and the TPC command within a period of time, and determines that the uplink has failed. It then notifies the uplink / beam failure UE to stop beam transmission or switch to other suitable cells or schedule the failed terminal to perform uplink transmission at a different time from the terminal that caused the gain compression.

[0556] In the above two schemes, the base station receives the information B reported by the repeater, which includes the total power of the signal received by the repeater and the gain of the repeater; the base station comprehensively judges whether the repeater amplifies the terminal signal according to the target gain based on the terminal's power headroom report (PHR) and transmit power control (TPC) command. The specific judgment method includes: Figure 9 For example, the base station schedules the uplink of UE1 and UE2 at the same time. The base station successfully demodulates the signal of UE1 but fails to demodulate the uplink signal of UE2. The base station obtains the following formula based on the reference signal received power and reference signal transmitted power of UE1:

[0557] UE1's reference signal received power - reference signal transmitted power = PL (path loss) between UE1 and the repeater + PL between the repeater and the base station - actual amplification gain of the repeater;

[0558] The base station then knows the PL between UE1 and the repeater + the PL between the repeater and the base station based on the gain of the repeater. The base station then determines the PL between UE1 and the repeater based on the total power of the signal received by the base station, thereby knowing the PL between the repeater and the base station.

[0559] For UE2, the base station can obtain the following formula based on the received UE2 reference signal received power and reference signal transmitted power:

[0560] UE2 reference signal received power - reference signal transmitted power = PL (path loss) between UE2 and the repeater + PL between the repeater and the base station - actual amplification gain of the repeater;

[0561] Since the PL (repeater gain) value between the repeater and the base station can be obtained based on the UE1 signal, the base station already knows the PL (path loss) between UE2 and the repeater. The base station then determines the signal power of UE2 received by the repeater based on the TPC and PHR of UE2, thereby determining that the cause of UE2's uplink failure is that the repeater gain is less than the target gain value.

[0562] Then the base station notifies UE2 to stop beam transmission or switch to other suitable cells or schedule the failed terminal and the terminal causing gain compression to perform uplink transmission at a different time.

[0563] Example 3

[0564] In this embodiment, the repeater directly notifies the terminal of the gain change indication information, such as Figure 10 Said method comprises:

[0565] Step 1: The repeater sends gain change indication information D to the terminal;

[0566] The information may be RRC signaling, MAC CE signaling, DCI indication, or broadcast information;

[0567] This information is used to assist the terminal in determining the cause of uplink failure.

[0568] The method for the repeater to distinguish between received signals from multiple terminals and the power of the signals received from the multiple terminals includes:

[0569] The base station informs the repeater of the DMRS patterns of the multiple terminals it serves. The repeater distinguishes different terminals by measuring the DMRS symbol power and evaluates the received signal power of each of the multiple terminals; or

[0570] The base station informs the repeater of the SRS reference symbol configuration of multiple terminals it serves. The repeater distinguishes different terminals by measuring the SRS symbol power and evaluates the signal power received from each of the multiple terminals.

[0571] The information includes an indication bit, the total power of the signal received by the repeater, the actual amplification gain of the repeater, the difference between the actual amplification gain of the repeater and the target gain (the gain difference of each terminal can be indicated separately), or one or more of the above information.

[0572] If the repeater cannot distinguish whether the received signals come from multiple terminals, then only one or more of the signal power received by the repeater and the actual amplification gain information of the repeater may be included;

[0573] The indication bit is used to indicate whether the repeater amplifies all terminal signals according to the target gain. For example, if the amplification gain of a terminal is less than the target gain, the indication bit is set to 1, otherwise it is set to 0.

[0574] The triggering conditions for the repeater to send the gain change indication information D include:

[0575] The repeater determines that the difference between the target gain and the actual gain amplified for at least one terminal is greater than a threshold value A; or,

[0576] Periodically triggered or semi-continuously scheduled by the base station.

[0577] Step 2: If the UE receives the gain compression information D sent by the repeater, it determines whether an uplink failure occurs. If an uplink failure occurs, it stops uplink transmission and waits for instructions from the base station.

[0578] a) Here, the reason for determining the uplink failure includes: whether a downlink feedback signal is received within a specified time window, etc. If not, it is determined that the uplink has failed.

[0579] It can be seen that the embodiment of the present invention can solve the technical problem that after the uplink fails, the terminal continuously attempts to increase the noise floor of the target base station, and can achieve the technical effect of reducing the power consumption of the terminal caused by the uplink transmission power.

[0580] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
