Description

Technical Field

[0001] The present invention relates to the field of wireless technology, and in particular to a data packet activation method, device, network equipment and terminal. Background Art

[0002] At present, if one bit is added to the physical downlink control channel (PDCCH) to indicate that the terminal device abandons the previously transmitted data packet and / or activates the packet convergence protocol (PDCP) duplication transmission and the corresponding lifetime of the new data packet, the signaling overhead of the 5G NR authorized spectrum system will increase, and this is contrary to the original intention of the design of the configuration authorization data retransmission mechanism under the 5G NR authorized spectrum system (configuration authorization data retransmission does not introduce feedback indication). In addition, according to the current 5G NR protocol, the introduction of hybrid automatic repeat request (HARQ) ACK / NACK feedback in the PDCCH under the 5G NR authorized spectrum system also requires the introduction of a configured grant retransmission timer (CGRT), which is not required in the 5G NR authorized spectrum system.

[0003] Therefore, the current NR authorized spectrum system has no specific technical implementation plan for how to notify the terminal to abandon the transmission of previous data packets and / or activate the PDCP duplication transmission of new data packets and the corresponding lifetime.

[0185] The following is an introduction to the embodiments of the present application in conjunction with the accompanying drawings. The data packet activation method, device, network device and terminal provided in the embodiments of the present application can be applied to a wireless communication system. The wireless communication system can be a system using the fifth generation (5th Generation, 5G) mobile communication technology (hereinafter referred to as a 5G system). It can be understood by those skilled in the art that the 5G NR system is only an example and is not a limitation.

[0186] See also Figure 1 , Figure 1 is a structural diagram of a network system to which the embodiments of the present application can be applied, such as Figure 1 As shown, it includes a user terminal 11 and a base station 12, wherein the user terminal 11 may be a user equipment (User Equipment, UE), for example: it may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a personal digital assistant (Personal Digital Assistant, referred to as PDA), a mobile Internet device (Mobile Internet Device, MID) or a wearable device (Wearable Device). It should be noted that the specific type of the user terminal 11 is not limited in the embodiment of the present application. The above-mentioned base station 12 may be a base station of 5G and later versions (for example: gNB, 5G NR NB), or a base station in other communication systems, or referred to as a node B. It should be noted that in the embodiment of the present application, only a 5G base station is taken as an example, but the specific type of the base station 12 is not limited.

[0187] First, some concepts related to the embodiments of the present invention are described as follows.

[0188] Currently, 5G NR needs to support a new URLLC QoS service with a lifetime. The specific configuration authorization scheduling transmission mechanism is as follows: Figure 2 As shown. Figure 2 The UE in the second configured grant opportunity (Configured grantoccasion, CGO), that is, CGO2, sends the second data packet (Mg2) to the gNB. If the gNB does not successfully receive Msg2, the gNB has two processing methods. The first processing method is to recover the data packet (Mg2) (which can be achieved through the current NR DG retransmission scheduling), and the second processing method is that the gNB abandons the data packet (Mg2) (because the end-to-end delay cannot be met). Therefore, it is necessary to consider how to use PDCCH to dynamically notify the UE to abandon the transmission of Msg2 (and / or) activate the PDCP duplication transmission of the third data packet Msg3 and the corresponding lifetime.

[0189] At present, in 5G NR, the configured grant scheduling transmission mechanism (Configured grant, CG) is actually like the semi-static scheduling in Long Term Evolution (LTE). The configured grant scheduling transmission mechanism CG is mainly used for uplink transmission. The base station (gNB) pre-configures the uplink physical shared channel (Physical Uplink Shared Channel, PUSCH) resources, and the terminal (User Equipment, UE) does not need to send an uplink scheduling request (SR) to the base station if there is uplink data to be sent. It can be sent directly on the CG resources. CG means that the gNB activates the uplink grant to the UE once. If the UE does not receive the deactivation, it will always use the resources specified by the uplink grant for uplink transmission. There are two types of transmission:

[0190] Configuration Grant CG type1: The Radio Resource Control (RRC) configures the uplink grant resources through high-level signaling (IE ConfiguredGrantConfig); the UE can use the resources specified by the uplink grant for uplink transmission without the need for an activation command;

[0191] Configuration grant CG type2: The activation and deactivation of uplink grant-free is indicated by the downlink control information (DCI). The required parameters are configured by IE ConfiguredGrantConfig, but it is only used when activated by DCI.

[0192] Configuration grant type 1 and configuration grant type 2 are distinguished based on the rrc-ConfiguredUplinkGrant field in IE ConfiguredGrantConfig. If this field is configured, it is configuration grant type 1. If this field is not configured, it is configuration grant type 2.

[0193] The gNB uses the Physical Downlink Control Channel (PDCCH) scrambled by the configured scheduling radio network temporary identifier (CS-RNTI) to dynamically reschedule the configured authorized data.

[0194] The embodiments of the present application provide a data packet activation method and apparatus to solve the problem in the prior art that a network device cannot instruct a terminal to abandon the transmission of a previous data packet and / or activate PDCP repeated transmission and corresponding lifetime of a new data packet.

[0195] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0196] like Figure 3 As shown, an embodiment of the present invention provides a data packet activation method, which is performed by a network device, and the method includes:

[0197] Step S301: In the uplink configuration authorization CG transmission, the physical downlink control channel PDCCH is used to instruct the terminal to stop the configuration authorization CG timer corresponding to the hybrid automatic request process number HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activate the data packet convergence protocol PDCP copy transmission and corresponding lifetime of the new data packet.

[0198] In the embodiment of the present invention, the new data packet refers to a data packet configured after the corresponding data packet when the CG timer (timer) stops.

[0199] In the uplink configuration authorization CG transmission, the network device uses PDCCH to notify the terminal to stop the CG timer corresponding to the hybrid automatic request process number (HARQ process number, HPN), and to effectively use the subsequent CGO for new data transmission and / or activate the data packet convergence protocol PDCP copy transmission and corresponding lifetime of new data packets.

[0200] Optionally, the physical downlink control channel PDCCH includes at least one of the following indication information, instructing the terminal to stop the configuration authorization CG timer corresponding to the hybrid automatic request process number HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activate the data packet convergence protocol PDCP copy transmission of the new data packet and the corresponding lifetime:

[0201] Hybrid Automatic Request Process Number HPN;

[0202] New data indicates NDI;

[0203] Redundancy version RV;

[0204] Frequency domain resource allocation FDRA;

[0205] Time Domain Resource Allocation TDRA;

[0206] Modulation and coding strategy MCS.

[0207] In an embodiment of the present invention, a network device sends an indication message to a terminal via a PDCCH, instructing the terminal to stop a configuration authorization CG timer corresponding to the HPN, and use a subsequent configuration authorization opportunity CGO for new data packet transmission and / or activation of a data packet convergence protocol PDCP copy transmission and a corresponding lifetime of the new data packet, wherein the indication message includes at least one of the following: a hybrid automatic request process number HPN to be stopped carried in the PDCCH; a new data indicator (NDI); a redundancy version (RV); a frequency domain resource allocation (FDRA); a time domain resource allocation (TDRA); and a modulation and coding scheme (MCS).

[0208] Optionally, when the indication information satisfies at least one of the following conditions, the terminal is instructed to stop a configuration authorization CG timer corresponding to the hybrid automatic request process number HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activation of the data packet convergence protocol PDCP copy transmission of the new data packet and the corresponding lifetime:

[0209] The value of the new data indication NDI is a first preset value, and the value of the redundant version RV is a second preset value; the value of the new data indication NDI is the first preset value used to indicate the newly transmitted data; the value of the redundant version RV is the second preset value used to indicate the starting data set of the corresponding transmission in the ring buffer;

[0210] The value of the new data indication NDI is a third preset value, and the value of the frequency domain resource allocation FDRA is a fourth preset value; the value of the new data indication NDI is the third preset value used to indicate retransmission data; the value of the frequency domain resource allocation FDRA is the fourth preset value used to indicate the maximum value, minimum value or preset allocation value of the frequency domain resource allocation;

[0211] The value of the hybrid automatic request process number HPN is a first preset value, and the value of the new data indication NDI is the first preset value; the value of the hybrid automatic request process number HPN is the first preset value used to indicate the hybrid automatic request process number HPN corresponding to a CG timer that needs to be stopped; the value of the new data indication NDI is the first preset value used to indicate new transmission data;

[0212] The value of the redundancy version RV is a fifth preset value; the value of the redundancy version RV is the fifth preset value used to indicate a starting data set corresponding to the transmission in the ring buffer;

[0213] The value of the time domain resource allocation TDRA is a sixth preset value; the value of the time domain resource allocation TDRA is the sixth preset value used to indicate the row number index in the time domain resource allocation table;

[0214] The value of the modulation and coding strategy MCS is a seventh preset value; the seventh preset value of the modulation and coding strategy MCS is used to indicate a modulation and coding strategy index.

[0215] Optionally, the second preset value is a non-zero value.

[0216] Optionally, when the frequency domain resource allocation type is type 0, the fourth preset value is an all-0 value;

[0217] When the frequency domain resource allocation type is type 1, the fourth preset value is an all-1 value.

[0218] In an embodiment of the present invention, when the indication information satisfies the following manner, the terminal may be instructed to stop a configuration authorization CG timer corresponding to the hybrid automatic request process number HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activation of the data packet convergence protocol PDCP copy transmission of the new data packet and the corresponding life time:

[0219] Method 1: The base station carries the process number HPN to be terminated in the PDCCH, the value of NDI is a first preset value, and the value of the redundant version RV is a second preset value. Preferably, the first preset value is 0, and the second preset value is a non-zero value. For example, NDI is set to 0 ("0" indicates new transmission data), and RV is set to a non-zero value (such as "1"), which can instruct the terminal to stop a configuration authorization CG timer corresponding to HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activate the data packet convergence protocol PDCP copy transmission of the new data packet and the corresponding lifetime.

[0220] Method 2: For CG type1 and CG type2, the network device uses the value of HPN as the first preset value, and the value of NDI is also the first preset value. Preferably, the first preset value is 0, and NDI is set to 0 ("0" indicates new transmitted data). That is, the network device uses HPN+NDI=0 to instruct the terminal to stop a configuration authorization CG timer corresponding to HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activate the data packet convergence protocol PDCP copy transmission of the new data packet and the corresponding lifetime.

[0221] Mode 3: The PDCCH carries the process number HPN to be terminated, the value of NDI is the third preset value, and the value of FDRA is the fourth preset value. Preferably, the third preset value is 1, and the fourth preset value is all 0 in type0, or all 1 in type1, or is the same as other preset special values. For example, NDI is set to 1 ("1" means retransmitted data), FDRA is set to all 0 or all 1 or a preset special value, which can instruct the terminal to stop a configuration authorization CG timer corresponding to HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activate the data packet convergence protocol PDCP copy transmission and the corresponding lifetime of the new data packet.

[0222] Method 4: On the basis of Method 3, further utilize at least one of the RV value being the fifth preset value, the TDRA value being the sixth preset value, and the MCS value being the seventh preset value to jointly instruct the terminal to stop a configuration authorization CG timer corresponding to the HPN, and use the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activation of the data packet convergence protocol PDCP copy transmission and the corresponding lifetime of the new data packet; wherein the value of TDRA depends on the number of configured rows.

[0223] Optionally, when the indication information satisfies the following conditions, the terminal is instructed to stop all configuration authorization CG timers corresponding to the hybrid automatic request process number HPN, and use subsequent configuration authorization opportunities CGO for new data packet transmission and / or activation of the data packet convergence protocol PDCP copy transmission of the new data packet and the corresponding lifetime:

[0224] The value of the new data indication NDI is the first preset value, the value of the redundant version RV is the eighth preset value, and the hybrid automatic request process number HPN is the ninth preset value; the value of the new data indication NDI is the first preset value used to indicate the newly transmitted data; the value of the redundant version RV is the eighth preset value used to indicate the starting data set corresponding to the transmission in the ring buffer; the hybrid automatic request process number HPN is the ninth preset value used to indicate the hybrid automatic request process number HPN corresponding to all the configured authorization CG timers before the new data packet.

[0225] In the embodiment of the present invention, for the network device to instruct the terminal to activate PDCP duplication transmission and the corresponding lifetime and terminate all previous processes, the PDCCH does not need to carry a specific process number HPN, only the NDI value needs to be 0 ("0" indicates new transmission data), and the RV is set to a non-zero value (such as: all "1"), HPN can be set to a special value (all 0 or all 1), and other uninvolved fields in the PDCCH are set to 0.

[0226] Optionally, the method further comprises:

[0227] The hybrid automatic request process number HPN carried by the physical downlink control channel PDCCH is scrambled by configuring the scheduling radio network identifier CS-RNTI to indicate the hybrid automatic request process number HPN corresponding to the CG timer that needs to be stopped.

[0228] Optionally, the method further comprises:

[0229] The new data packet sent by the terminal is received.

[0230] In the embodiment of the present invention, after determining the HPN corresponding to the CG timer that needs to be stopped, the terminal sends a new data packet to the network device.

[0231] In the embodiment of the present invention, the network device uses the CS-RNTI to scramble the process number to be terminated carried in the PDCCH.

[0232] Correspondingly, after the terminal sends a data packet on the CG, it uses the CS-RNTI to monitor the dynamically scheduled retransmission PDCCH.

[0233] Combine the following Figure 4 , specifically describe one of the PDDCH signaling indication methods.

[0234] The network device carries the process number HPN to be terminated in the dynamic scheduling PDCCH encrypted with CS-RNTI, NDI is set to 0 ("0" indicates new transmission data, "1" indicates retransmission data) and RV is set to a non-zero value (such as: all "1"), indicating that the terminal stops the CG timer corresponding to HPN, and the subsequent CGO can be effectively used for new data transmission and / or activation of PDCP duplicate transmission and corresponding life time of new data packets. Other unrelated fields in PDCCH are set to 0.

[0235] First, the terminal sends data on the CG resource of the network device and starts the CG timer.

[0236] Secondly, when the network device fails to receive data, the network device triggers the terminal to stop the CGtimer corresponding to the HPN, and uses the subsequent CGO for new data transmission and / or activates the PDCP copy transmission and corresponding life time of the new data packet, and sends the PDCCH encrypted by the CS-RNTI to the terminal. The PDCCH carries the process number HPN to be terminated, NDI is set to 0 ("0" indicates new transmission data, "1" indicates retransmission data), and RV is set to a non-zero value (such as: all "1") to instruct the terminal to stop the CG timer corresponding to the HPN, and at the same time, the subsequent CGO can be effectively used for new data transmission and / or activate the PDCP copy transmission and corresponding life time of the new data packet. In this embodiment, the PDCCH carries the indication information field as shown in Table 1.

[0237] Table 1 PDCCH bearer indication information field

[0238] PDCCH DCI format HPN (HARQ process number) correspond to discarded PDU NDI set to '0' Redundancy version set to not all'0's

[0239] To further illustrate, for CG type1 and CG type2, the network device can use HPID+NDI=0 to instruct the terminal to stop the CG timer corresponding to HPN, and at the same time enable subsequent CGO to be effectively used for new data transmission and / or activate PDCP duplication transmission and corresponding lifetime of new data packets. For instructing the terminal to activate PDCP duplication transmission and corresponding lifetime or terminate all previous processes, the PDCCH does not need to carry a specific process number HPN, only NDI=0+RV needs to be set to a non-zero value (such as: all "1"), and HPN can be set to a special value (all "0" or all "1").

[0240] Then, after the terminal sends a data packet on the CG, it monitors the dynamic retransmission scheduling PDCCH with CS-RNTI. When the process number HPN indicated in the PDCCH is received, NDI is set to 0 ("0" indicates new transmission data, "1" indicates retransmission data) and RV is set to a non-zero value (such as: all "1"), the terminal stops the CG timer corresponding to HPN, and uses the subsequent CGO for new data transmission and / or activating the PDCP duplication transmission and corresponding life time of the new data packet. Further explanation, for CG type1 and CGtype2, if the terminal receives HPID+NDI=0, the terminal will stop the CG timer corresponding to HPN and use the subsequent CGO for new data transmission and / or activating the PDCP duplication transmission and corresponding life time of the new data packet. For instructing the UE to activate the PDCP duplication transmission and the corresponding life time or terminate all previous processes, if the UE receives NDI=0+RV is set to a non-zero value (such as: all "1") and HPN is set to a special value (all "0" or all "1"), the terminal activates the PDCP duplication transmission and the corresponding life time or terminates all previous processes. In order to solve the problem that the terminal fails to detect PDCCH and cannot stop the CG timer corresponding to the HPN and / or activate the PDCP copy transmission and corresponding survival time of the new data packet, a survival timer can be set on the terminal side. If the terminal still does not receive the corresponding PDCCH indication information after the survival timer times out, the terminal will use the subsequent CGO for new data transmission and / or activate the PDCP copy transmission and corresponding survival time of the new data packet and stop the CG timer corresponding to the HPN.

[0241] Combine the following Figure 5, specifically explain the second PDDCH signaling indication method.

[0242] The PDCCH carries the process number HPN to be terminated, NDI is set to 1 ("0" indicates new data transmission, "1" indicates retransmission data) and the FDRA can pre-set a special value (type 0 all "0" or type 1 all "1") to instruct the terminal to stop the CG timer corresponding to the HPN and enable subsequent CGO to be effectively used for new data transmission and / or activation of PDCP duplicate transmission of new data packets and the corresponding life span. Other unrelated fields in the PDCCH are set to 0.

[0243] First, the terminal sends data on the CG resources of the gNB and starts the CG timer.

[0244] Secondly, when the network device fails to receive data, the network device triggers the UE to stop the CG timer corresponding to the HPN and use the subsequent CGO for new data transmission and / or activation of the PDCP duplicate transmission and the corresponding life time of the new data packet, and sends the PDCCH encrypted by the CS-RNTI to the terminal. The PDCCH carries the process number HPN to be terminated, the NDI is set to 1 ("0" indicates new transmission data, "1" indicates retransmission data) and the FDRA can be a pre-set special value (type 0 all "0" or type 1 all "1"). On this basis, at least one of the preset special values ​​in RV, TDRA (depending on the number of configured rows) and MCS can be further used for joint indication. This method can be used to instruct the terminal to stop the CG timer corresponding to the HPN and enable the subsequent CGO to be effectively used for new data transmission and / or activation of the PDCP duplicate transmission and the corresponding life time of the new data packet. In this embodiment, the PDCCH carries the indication information field as shown in Table 2.

[0245] Table 2 PDCCH bearer indication information field

[0246]

[0247] Then, after the terminal sends the data packet on the CG, it uses the CS-RNTI to monitor the dynamic retransmission scheduling PDCCH. When the process number HPN indicated in the PDCCH is received, NDI is set to 1 ("0" indicates new transmission data, "1" indicates retransmission data) and FDRA is a pre-set special value (type 0 all "0" or type 1 all "1"), the terminal stops the CG timer corresponding to the HPN and uses the subsequent CGO for new data transmission and / or activates the PDCP copy transmission of the new data packet and the corresponding lifetime.

[0248] In an embodiment of the present invention, the network device uses indication fields such as HPN and NDI in the PDCCH to notify the terminal to abandon the previously transmitted data packets and / or activate the PDCP copy transmission and corresponding lifetime of the new data packets, which can further improve the reliability of data transmission while reducing the waste of air interface resources and thus better support the QoS of the new URLLC with lifetime.

[0249] It should be noted that the embodiment of the present invention instructs the terminal to stop the configuration authorization CG timer corresponding to the hybrid automatic request process number HPN through the physical downlink control channel PDCCH in the uplink configuration authorization CG transmission, and uses the subsequent configuration authorization opportunity CGO for new data packet transmission and / or activates the data packet convergence protocol PDCP copy transmission and the corresponding life time of the new data packet. This can enable the network device to instruct the terminal through the PDCCH to abandon the previously transmitted data packet and activate the PDCP copy transmission and the corresponding life time of the new data packet, thereby improving the reliability of the data and reducing the waste of air interface resources, thereby better supporting the service quality of new ultra-reliable low-latency communications with life time.
