[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This application claims priority to Chinese patent application number 202311643555.3 filed on December 1, 2023, entitled “A data transmission method, device, communication equipment and storage medium,” the entire contents of which are incorporated by reference into this application. Technical Field
[0003] The present application belongs to the field of communication technology, and specifically relates to a data transmission method, apparatus, communication equipment and storage medium. Background Art
[0004] In the New Radio (NR) communication system, the air interface of the terminal has three states: Radio Resource Control (RRC) idle state (IDLE), RRC inactive state (INACTIVE) state and RRC connected state (CONNECTED).
[0005] Among them, a terminal in the RRC idle state has no connection to the base station (gNB) and only needs to periodically initiate location updates, cell selection and reselection processes, and receive paging. A terminal in the RRC inactive state does not need to notify the base station when moving within the notification area (RAN based Notification Area, RNA) of the radio access network (RAN), and the terminal will retain some configurations. In the RRC connected state, the terminal remains connected to the network.

The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home evolved Node B (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the relevant field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.
[0053] To facilitate understanding of the data transmission method according to the embodiment of the present application, the following related technologies are first introduced:
[0054] 1. Paging Classification
[0055] In NR, paging can be divided into the following types according to the source of the message:
[0056] 5G core network (5GC) paging: The paging is initiated by the 5GC. In the radio resource control idle (RRC_IDLE) state, when downlink data arrives for the UE in the RRC_IDLE state, the 5GC notifies the UE through a Paging message.
[0057] Radio Access Network (RAN) paging: Paging is initiated by the RAN. When downlink data arrives for a UE in the Radio Resource Control Inactive (RRC_INACTIVE) state, the gNB notifies the UE via a Paging message.
[0058] The final paging message is sent by the gNB to the UE via the air interface.
[0059] 2. Paging Channel
[0060] The paging message is carried by the Paging Control Channel (PCCH), and the data block of the PCCH logical channel is carried by the Paging Channel (PCH) transport channel, and the data block of the PCH transport channel is carried by the Physical Downlink Shared Channel (PDSCH) physical channel. Since PDSCH is a downlink shared physical channel, it can carry not only the PCH transport channel but also the downlink shared channel (DL-SCH) transport channel. Therefore, before receiving a paging message (on PDSCH), the terminal needs to first monitor the PDCCH physical channel, and then determine whether the network has sent a paging message to itself in this paging cycle based on whether the PDCCH physical channel carries the Paging Radio Network Temporary Identifier (P-RNTI).
[0061] In addition to sending a paging message, the DCI for scheduling paging may also carry a short message and indicate whether there are available Tracking Reference Signal (TRS) resources.
[0062] 3. Paging Occasion (PO) and Paging Frame (PF)
[0063] A paging frame is a radio frame that may contain one or more paging occasions; a paging occasion is a subframe that may contain a paging message.
[0064] The terminal knows the paging cycle, PF, and PO, and can know the exact time to receive the paging message. In order to reduce the power consumption of the UE in the RRC_IDLE / RRC_INACTIVE state, the UE uses discontinuous reception (DRX) to receive the paging message.
[0065] There are several PFs in a DRX cycle, and one PF corresponds to several POs. The UE only wakes up once in a DRX cycle to monitor one PO. The UE monitors one PO in each DRX cycle.
[0066] In addition, PO is a set of physical downlink control channel (PDCCH) monitoring opportunities and may include multiple time slots (eg, subframes or OFDM symbols) in which paging DCI may be transmitted.
[0067] In addition, DRX cycle indicates the period of UE detection of paging, PF indicates the system frame for detecting paging, PO indicates the specific PDCCH monitoring occasions for detecting paging, and i_s indicates the index of PO corresponding to PF. The relevant calculation methods are as follows: PF: (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) i_s: i_s=floor(UE_ID / N)mod Ns
[0068] Wherein, the above T represents the DRX cycle; there will be a cell-level indication Tc in the system message, and RRC may also have a UE-level indication Tue. If Tue is not indicated, then T = Tc; if Tue is indicated, then T = min(Tc, Tue);
[0069] N represents the total number of PFs in T;
[0070] Ns represents the number of POs corresponding to a PF;
[0071] PF_offset indicates the offset of PF;
[0072] UE_ID represents 5G-S-TMSI mod 1024, TMSI represents the temporary mobile subscriber identification code (Temporary Mobile Subscriber Identify) of the UE, which can be used to uniquely distinguish different UEs; when the UE does not have a TMSI, the default UE_ID = 0.
[0073] It should be noted that the above parameters will be indicated in the PCCH configuration information (PCCH-config).
[0074] 4. Paging Message
[0075] A paging message carries a paging record list (PagingRecordList), which contains at least one and at most maxNrofPageRec PagingRecords. Each PagingRecord carries a paging identifier (ue_Identity) of the paged UE. That is, a paging message can indicate that at most maxNrofPageRec UEs are paged.
[0076] There are two types of identifiers for the paged UE: one for the UE in the idle state, such as ng-5G-S-TMSI; the other for the UE in the inactive state, such as fullI-RNTI. The UE receiving the paging message is in either the idle state or the inactive state.
[0077] The data transmission method provided in the embodiments of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.
[0078] In a first aspect, an embodiment of the present application provides a data transmission method. As shown in FIG2 , the method may include the following steps 201 to 202:
[0079] Step 201: The terminal receives target data through a target resource in a non-connected state.
[0080] The target resource includes at least one of a paging resource configured for paging, a specific resource configured for a non-connected state, a first resource associated with the paging resource, and a second resource associated with the specific resource.
[0081] The terminal can receive the target data sent by the network side device through the paging resource, and the network side device can send the target data to the terminal through the paging resource during the paging process; or, the terminal can receive the target data sent by the network side device through a specific resource or a first resource associated with the paging resource or a second resource associated with the specific resource in a non-connected state, and the network side device can send the target data to the terminal through a specific resource or a first resource associated with the paging resource or a second resource associated with the specific resource when the terminal is in a non-connected state.
[0082] It can be seen that in the embodiment of the present application, the target data includes data sent by the network side device when the terminal is in a non-connected state.
[0083] Step 202: The terminal receives a target transmission related to the target data.
[0084] The target transmission includes at least one of data repetition and data retransmission.
[0085] It can be understood that the terminal receiving the target transmission related to the target data may include: the terminal receiving the target data sent by means of target transmission (such as data repeated transmission or data retransmission).
[0086] It should be noted that the difference between data retransmission and data retransmission is that data retransmission is the repeated transmission of the same data N times, where N is greater than or equal to 1, that is, data retransmission is a known number of N transmissions; data retransmission is after one transmission, the decision on whether to transmit again is made. Therefore, although data retransmission may also be multiple transmissions, the number of transmissions is not known in advance.
[0087] In one embodiment, the target transmission related to the target data may be sent by a network side device (eg, a base station), that is, the network side device performs at least one of data retransmission and data retransmission on the target data.
[0088] Optionally, the disconnected state includes at least one of the following states:
[0089] Radio Resource Control-Idle (RRC-idle) state, Radio Resource Control-Inactive (RRC-inactive) state, standby state introduced in 6G or future mobile communication systems, state after Radio Resource Control release (RRC release) but before random access, and other non-connected states before random access.
[0090] It can be seen from the above steps 201 to 202 that in an embodiment of the present application, the terminal can receive target data through the target resource in a non-connected state, and the target resource includes at least one of a paging resource configured for paging, a specific resource configured for a non-connected state, a first resource associated with the paging resource, and a second resource associated with the specific resource; and the terminal can also receive a target transmission related to the target data, wherein the target transmission includes at least one of data retransmission and data retransmission. It can be seen that in an embodiment of the present application, the network side device can send target data to the non-connected terminal, and for this part of the data, at least one of data retransmission and data retransmission can also be performed, thereby improving the reliability of data transmission. Therefore, an embodiment of the present application provides a data transmission scheme between a network side device and a non-connected terminal.
[0091] Optionally, step 202, “the terminal receives the target transmission related to the target data”, includes:
[0092] The terminal receives the target transmission related to the target data according to the target information;
[0093] The target information includes at least one of the following items A-1 to A-5:
[0094] Item A-1: first indication information, the first indication information being used to indicate whether the terminal supports repeated data transmission in a non-connected state;
[0095] Item A-2: The target number of times the data is repeatedly transmitted;
[0096] Item A-3: a first resource for repeated transmission of the data;
[0097] Item A-4: beam for repeated data transmission;
[0098] Item A-5: A second resource used for retransmission of the data.
[0099] In one embodiment, the terminal receives repeated transmission of data related to the target data according to at least one of items A-1 to A-4.
[0100] In one embodiment, the terminal receives a retransmission of data related to the target data according to item A-5.
[0101] Optionally, the first indication information satisfies at least one of the following:
[0102] The first indication information is carried in a system message;
[0103] The first indication information is carried in Radio Resource Control (RRC) signaling;
[0104] The first indication information is carried in an RRC release message;
[0105] The first indication information is carried in a Media Access Control Control Element (MAC CE);
[0106] The first indication information is carried in a physical downlink control channel (PDCCH) for scheduling data transmission;
[0107] The first indication information is carried in downlink control information (Downlink Control Information, DCI) for scheduling data transmission;
[0108] The first indication information is carried in resources transmitted for the first time;
[0109] The first indication information is determined according to whether the terminal supports data retransmission in a connected state (if the terminal supports data retransmission in a connected state, the terminal also supports data retransmission in a non-connected state; if the terminal does not support data retransmission in a connected state, the terminal also does not support data retransmission in a non-connected state);
[0110] The first indication information is determined according to the capability of the terminal.
[0111] From this, we can see that whether the terminal supports repeated data transmission in a non-connected state can be configured by the network side device or agreed upon by the protocol.

[0145] Item B-6: The target number is the common number of repeated transmissions.
[0146] In item B-6, the common number of repeated transmissions can be applied to data repeated transmission in different scenarios; for example, the network-side equipment configuration or protocol provisions specify the common number of repeated transmissions of related channel signals for non-connected terminals and terminals in the process of contention-based random access.
[0147] Optionally, the first resource includes a continuous first available resource, wherein the first available resource satisfies at least one of the following conditions C-1 to C-7:

[0219] Item E-15: The second resource includes a common transmission resource;

[0226] It should be noted that the above-mentioned first resources (resources for repeated data transmission) and second resources (resources for data retransmission) are based on physical time units or available time units, which can be configured by network side equipment or agreed upon by protocol.
[0227] In addition, the first resource and the second resource mentioned above can both be a broadcast channel, a multicast channel, or a unicast channel.

[0240] It can be seen from item F-1 that the network side device can perform at least one of automatic retransmission and feedback retransmission on the target data when the terminal is in a non-connected state; in this case, when the terminal is in a non-connected state, it can receive at least one of automatic retransmission and feedback retransmission for the target data.
[0241] It can be seen from item F-2 that the network side device can also perform at least one of automatic retransmission and feedback retransmission on the target data after the terminal enters the connected state; in this case, after the terminal is in the connected state, it can receive at least one of automatic retransmission and feedback retransmission for the target data.
[0242] As shown in item F-3, the network device can perform "at least one of automatic retransmission and feedback retransmission" on the target data X times when the terminal is in the disconnected state, and then perform "at least one of automatic retransmission and feedback retransmission" Y times after the terminal enters the connected state. For example, the network device can perform "automatic retransmission" on the target data X times when the terminal is in the disconnected state, and then perform "automatic retransmission" Y times after the terminal enters the connected state; alternatively, the network device can perform "feedback retransmission" on the target data X times when the terminal is in the disconnected state, and then perform "feedback retransmission" Y times after the terminal enters the connected state.

[0250] It can be seen from item J-1 that the automatic retransmission can be performed at any time after the first timer is started, and retransmission cannot be performed after the first timer times out.
[0251] Item J-2: When a second timer expires (or becomes invalid), the terminal receives a retransmission of data related to the target data; wherein the second timer starts timing in a time slot next to the time slot in which the first data transmission of the target data occurs or in a downlink time slot;
[0252] It can be seen from item J-2 that automatic retransmission can be started when the second timer expires.
[0253] Item J-3: the terminal receives a retransmission of data related to the target data within a first time window;
[0254] From item J-3, we can see that automatic retransmission can be performed within the first time window;
[0255] Item J-4: The terminal receives a retransmission of data related to the target data at the first time after receiving the first data transmission of the target data.
[0256] It can be seen from item J-4 that there may be a time domain offset, and retransmission is performed after the first data transmission of the target data + the time domain offset.
[0257] Optionally, when the first behavior includes receiving a feedback retransmission related to the target data, the terminal receiving the feedback retransmission includes at least one of the following K-1 to K-6:
[0258] K-1 item: if the terminal sends feedback information for the target data, the terminal does not receive retransmission of data related to the target data;

[0260] Item K-2: when the terminal sends feedback information for the target data, the terminal receives retransmission of data related to the target data;
[0261] If the terminal sends feedback information for the target data to the network side device, then the terminal can also receive subsequent data retransmissions of the target data;
[0262] Item K-3: If the terminal does not send feedback information for the target data, the terminal does not receive retransmission of data related to the target data;
[0263] If the terminal does not send feedback information for the target data to the network side device, then the terminal may not receive subsequent data retransmissions of the target data;
[0264] Item K-4: when the terminal does not send feedback information for the target data, the terminal receives retransmission of data related to the target data;
[0265] If the terminal does not send feedback information for the target data to the network side device, then the terminal may also receive subsequent data retransmissions of the target data;

[0267] If the terminal sends feedback information for the target data to the network side device, and the feedback information is ACK feedback information, then the terminal may not receive subsequent data retransmissions of the target data;
[0268] Item K-6: When the terminal sends feedback information indicating non-acknowledgement (NACK) of the target data, the terminal receives retransmission of data related to the target data.
[0269] If the terminal sends feedback information for target data to the network-side device, and the feedback information is NACK feedback information, then the terminal can receive subsequent data retransmission of the target data.
[0270] Optionally, the feedback information may be Hybrid Automatic Repeat Request (HARQ) feedback information, and the feedback retransmission may be HARQ retransmission.

[0272] The terminal receives the repeated transmission of the data related to the target data on a specific PDSCH.
[0273] It can be seen from this that the network side device can perform data retransmission on the target data only for a specific PSDCH.
[0274] It should also be noted that whether different terminals support data retransmission in a non-connected state may be different. Therefore, the network side device can perform data retransmission only for some terminals; it can also perform data retransmission for all terminals.
[0275] In a second aspect, an embodiment of the present application further provides a data transmission method. As shown in FIG3 , the method may include the following steps 301 to 302:
[0276] Step 301: When the terminal is in a non-connected state, the network side device sends target data to the terminal through the target resource.
[0277] The target resource includes at least one of a paging resource configured for paging, a specific resource configured for a non-connected state, a first resource associated with the paging resource, and a second resource associated with the specific resource.
[0278] The terminal can receive the target data sent by the network side device through the paging resource, and the network side device can send the target data to the terminal through the paging resource during the paging process; or, the terminal can receive the target data sent by the network side device through a specific resource or a first resource associated with the paging resource or a second resource associated with the specific resource in a non-connected state, and the network side device can send the target data to the terminal through a specific resource or a first resource associated with the paging resource or a second resource associated with the specific resource when the terminal is in a non-connected state.
[0279] It can be seen that in the embodiment of the present application, the target data includes data sent by the network side device when the terminal is in a non-connected state.
[0280] Step 302: The network-side device sends a target transmission related to the target data.
[0281] The target transmission includes at least one of data repetition and data retransmission.
[0282] It should be noted that the difference between data retransmission and data retransmission is that data retransmission is the repeated transmission of the same data N times, where N is greater than or equal to 1, that is, data retransmission is a known number of N transmissions; data retransmission is after one transmission, the decision on whether to transmit again is made. Therefore, although data retransmission may also be multiple transmissions, the number of transmissions is not known in advance.
[0283] Optionally, the disconnected state includes at least one of the following states:
[0284] Radio Resource Control-Idle (RRC-idle) state, Radio Resource Control-Inactive (RRC-inactive) state, standby state introduced in 6G or future mobile communication systems, state after Radio Resource Control release (RRC release) but before random access, and other non-connected states before random access.
[0285] It can be seen from the above steps 301 to 302 that in an embodiment of the present application, the network side device can send target data to the terminal through the target resource when the terminal is in a non-connected state, and the target resource includes at least one of a paging resource configured for paging, a specific resource configured for a non-connected state, a first resource associated with the paging resource, and a second resource associated with the specific resource; and the network side device can also send a target transmission related to the target data, wherein the target transmission includes at least one of data retransmission and data retransmission. It can be seen that in an embodiment of the present application, the network side device can send target data to a non-connected terminal, and for this part of the data, at least one of data retransmission and data retransmission can also be performed, thereby improving the reliability of data transmission. Therefore, an embodiment of the present application provides a data transmission scheme between a network side device and a non-connected terminal.

[0378] It can be seen from item L-1 that the automatic retransmission can be performed at any time after the first timer is started, and retransmission cannot be performed after the first timer times out.
[0379] Item L-2: When the second timer times out, the network-side device retransmits data related to the target data; wherein the second timer starts timing in a time slot next to the time slot in which the first data transmission of the target data occurs or in a downlink time slot;
[0380] It can be seen from item L-2 that automatic retransmission can be started when the second timer expires.

[0401] Alternatively, for example, if the network-side device does not receive HARQ feedback information within a certain period of time after sending the target data, a retransmission timer is triggered; wherein, retransmission can be performed within the timer or after the timer expires;

[0405] If the network side device receives feedback information for target data sent by the terminal, and the feedback information is NACK feedback information, then the network side device may send data retransmission of the target data.
[0406] For example, the network-side device immediately retransmits after receiving HARQ NACK feedback;
[0407] Alternatively, for example, the network-side device retransmits within a period of time (e.g., within a timer / window) after receiving HARQ NACK feedback;

[0410] The network side device sends the data related to the target data repeatedly on a specific PDSCH.
[0411] It can be seen from this that the network side device can perform data retransmission on the target data only for a specific PSDCH.
[0412] It should also be noted that whether different terminals support data retransmission in a non-connected state may be different. Therefore, the network side device can perform data retransmission only for some terminals; it can also perform data retransmission for all terminals.
