Technical field

The present application belongs to the field of communication technology, and specifically relates to an extended discontinuous reception configuration method and device, and communication equipment.

Background technique

In the related art, when the terminal is in an idle state, the terminal cannot be positioned. If you want to support the positioning of idle state terminals, you need to solve the problem that when configuring the Core Network (CN) extended DRX cycle (eDRX), the idle state detection reference signal (Sounding Reference Signal, SRS) should How to configure or measure the idle positioning reference signal PRS.

In addition, taking into account the power saving mechanism, it is possible to introduce the extended DRX cycle (eDRX) of the core network in the inactive state in the future, or the extended DRX cycle (eDRX) of the RAN greater than 10.24s. . In this case, how does the network side device confirm the DRX where the terminal is located, and/or how to configure the detection reference signal or positioning reference signal PRS window under DRX.

Based on the existing process, the configuration information of CN eDRX/DRX is sent to the terminal by the Access and Mobility Management Function (AMF) when the terminal registers; while the base station is in the paging message. The relevant configuration obtained, but the current inactive SRS configuration information is carried by the base station in the Radio Resource Control (Radio Resource Control, RRC) release message. That is to say, when the base station configures the SRS configuration information, it may not know the CN eDRX configuration information, resulting in the SRS configuration not matching the CN eDRX/DRX configuration information, and affecting the terminal's power saving or positioning functions. In addition, the Location Management Function (LMF) may recommend SRS configuration information to the base station, but LMF neither knows the configuration information of CN eDRX/DRX nor the configuration information of RAN eDRX/DRX, which may cause the recommended The SRS configuration cannot match the DRX configuration information.

Both LTE and NR have introduced the DRX mechanism. DRX means discontinuous reception. By configuring the DRX on (on) and off (off) time, the UE can save power. As shown in Figure 2, the on duration is the DRX on interval. If there is no scheduling, the UE will enter the off period of a DRX cycle after the on duration.

When configuring DRX, the duration timer (onDurationTimer), the discontinuous reception inactivity timer (drx-InactivityTimer), the discontinuous reception forwarding timer (drx-RetransmissionTimer), and the starting offset of the long discontinuous reception cycle will be configured. (longDRX-CycleStartOffset) and other parameters.

After the UE is configured with DRX, if the decoding of data sent or received fails, the UE needs to enter the activation time to monitor the control channel and wait for retransmission scheduled by the network.

During the On Duration period, if the UE is scheduled and receives data in a certain time slot, it is likely to continue to be scheduled in the next few slots. Therefore, whenever the UE is scheduled to initially transmit data, the timer drx-InactivityTimer is started or restarted, and the UE will remain in the active state until the timer times out.

For downlink data reception, the UE will send data to the corresponding HARQ process after receiving the downlink data transmission indicated by the Physical downlink control channel (PDCCH) and feeding back the Hybrid Automatic Repeat Request (HARQ) information. Start the downlink return timer (HARQ RTT (Round Trip Time) Timer). If the HARQ RTT Timer times out and the data of the HARQ process is not successfully decoded, the UE starts the retransmission timer (drx-RetransmissionTimer) and listens to the PDCCH, waiting for transmission.

For uplink data transmission, the UE will start the uplink return timer HARQ RTT Timer for the corresponding HARQ process after receiving the PDCCH to indicate uplink data transmission. After the HARQ RTT Timer times out, the UE starts the retransmission timer (drx-ULRetransmissionTimer) and enters the active state to listen to the PDCCH and wait for the transmission scheduled by the network.

In idle mode, the maximum DRX cycle of traditional LTE is 2.56s, and frequent wake-ups consume UE power. In order to reduce power consumption and extend standby time, eDRX mode is introduced. eDRX is Extended idle-mode DRX cycle, extended discontinuous reception. In each eDRX cycle, the terminal in this mode can receive downlink data only within the set paging time window (PTW). The terminal is in a dormant state for the rest of the time and does not receive downlink data. There are high requirements for downlink business latency. The IoT platform can cache messages or send messages immediately according to whether the device is in a dormant state. Later, the eDRX was also introduced into the inactive state.

As shown in Figure 3, TeDRX_CN can be several superframes (H-SFN), TeDRX_CN=2,...,1024. Among them, one H-SFN corresponds to 1024 system frame numbers (SFN), that is, one superframe is equal to 10.24s, and the maximum period of H-SFN is 1024 H-SFNs, corresponding to 2.9127hour.

After the introduction of superframe, the following concepts were also introduced: PH: paging Hyperframe, which is the superframe number where the paging message is located, the unit is H-SFN;

PTW:paging Time Window, paging time window, SFN range within PH [PTW_start,PTW_stop];

PTW_start: The starting position of PTW, unit SFN;

PTW_stop: The end position of PTW, unit SFN.

If you want to support positioning of idle terminals, the existing technology has the following problems:

(1) Based on the existing process, the CN eDRX/DRX configuration information is sent to the terminal by the Access and Mobility Management Function (AMF) when the terminal registers; while the base station is paging ) message, but the current inactive SRS configuration information is carried by the base station in a Radio Resource Control (RRC) release message. That is to say, when the base station configures the SRS configuration information, it may not know the CN eDRX configuration information, causing the SRS configuration to fail to match the CN eDRX/DRX configuration information and affecting the power saving or positioning functions of the terminal. In addition, the Location Management Function (LMF) may recommend SRS configuration to the base station information, but LMF neither knows the configuration information of CN eDRX/DRX nor the configuration information of RAN eDRX/DRX, which may cause the recommended SRS configuration to fail to match the DRX configuration information.

(2) The applicable scope of existing SRS is as follows, which can be understood as the applicable scope of a specific cell (cell-specific), but this may not be enough for idle UEs:

(a) Tracking area (TA) verification area;

TA timer, timeout is considered invalid;

Exceeding the RSRP threshold is considered a failure;

(b) Cell reselection.

For problem (1), what needs to be solved is how the UE's CN eDRX configuration information interacts with the base station to which it belongs in a timely manner; for problem (2), what needs to be solved is the SRS configuration method within the TA or multi-cell area, so as to be applicable For UE in idle or inactive state, the eDRX state will not be frequently interrupted, affecting power saving.

Wherein, when the first auxiliary information sent by the first terminal includes the configuration information of the RAN eDRX with a tendency greater than 10.24, the starting position H-SFN of the PTW can be calculated according to the following formula:

H-SFN modT _{eDRX_RAN} = (UE_ID_H mod T _{eDRX_RAN} ), (Formula 1) or

H-SFN modT _{eDRX_CN} = (UE_ID_H modT _{eDRX_CN} ), (Formula 2)

Among them, T _{eDRX_CN} is the cycle of CN eDRX, and T _{eDRX_RAN} is the cycle of RAN eDRX. T _{eDRX_RAN} can be equal to T _{eDRX_CN} , or it can take the minimum value of the configured RAN eDRX cycle and T _{eDRX_CN} .

Optionally, in one case, the starting position H-SFN of the PTW on the CN side is obtained according to Formula 2. To ensure that the RAN side is aligned with the CN side, the expected eDRX cycle of the RAN side is that of the CN side. The common denominator is that either the starting position of the PTW calculated on the RAN side includes the H-SFN on the CN side, or the starting position of the PTW calculated on the RAN side is the H-SFN on the CN side.
