Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a data transmission method, apparatus, communication device, and storage medium. Background Art

[0002] In a New Radio (NR) communication system, there are three states for the air interface of a terminal: Radio Resource Control (RRC) idle state (IDLE), RRC inactive (INACTIVE) state, and RRC connected (CONNECTED) state.

[0003] Among them, a terminal in the RRC idle state is not connected to a base station (gNB), and only needs to periodically initiate location updates, cell selection and reselection processes, and receive paging, etc.; a terminal in the RRC inactive state does not need to notify the base station when moving within the Radio Access Network (RAN) based Notification Area (RNA) range, and the terminal will retain some configurations; in the RRC connected state, the terminal remains connected to the network.

[0004] Currently, when a terminal is in the connected state, the terminal can perform data transmission with a network-side device. For example, the terminal sends data to the network-side device, or the terminal receives data sent by the network-side device, to achieve uplink or downlink data transmission. It can be seen that data transmission between a connected-state terminal and a network-side device can be achieved in the prior art.

Among them, the access network device can also be called a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device can include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node, etc.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, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0049] To facilitate the understanding of the data transmission method in the embodiments of this application, the following related technologies are first introduced:

[0050] I. Paging Classification

[0051] In NR, according to the message source, paging can be divided into:

[0052] 5G Core Network (5GC) paging, that is, the paging is initiated from the 5GC. When there is downlink data arriving for a UE in the Radio Resource Control idle (RRC_IDLE) state, the 5GC notifies the UE through a Paging paging message.

[0053] Radio Access Network (RAN) paging, that is, the paging is initiated from the RAN. When there is downlink data arriving for a UE in the Radio Resource Control inactive (RRC_INACTIVE) state, the gNB notifies the UE through a Paging paging message.

[0054] The final paging message is sent by the gNB to the UE through the air interface.

[0055] II. Paging Channel

[0056] The paging message is carried by the Paging Control Channel (PCCH). 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 the PDSCH is a downlink shared physical channel, in addition to carrying the PCH transport channel, it can also carry the Downlink Shared Channel (DL-SCH) transport channel. Therefore, before receiving the paging message (on the PDSCH), the terminal needs to first monitor the Physical Downlink Control Channel (PDCCH), and then determine whether the network has sent a paging message to itself in this paging cycle according to whether the PDCCH carries the Paging Radio Network Temporary Identifier (P-RNTI).

[0057] Among them, in addition to sending paging messages, the DCI scheduling paging can also carry short messages and indicate whether there are available Tracking Reference Signal (TRS) resources.

[0058] III. Paging Occasion (PO) and Paging Frame (PF)

[0059] The paging frame is a radio frame that can contain one or more paging occasions; the paging occasion is a subframe that may contain a paging message.

[0060] If the terminal knows the paging cycle, PF, and PO, it can know the exact time to receive the paging message. To reduce the power consumption of the UE in the RRC_IDLE / RRC_INACTIVE state, the UE uses Discontinuous Reception (DRX) to receive paging messages.

[0061] Among them, there are several PFs in one DRX cycle, one PF corresponds to several POs, and the UE wakes up only once in one DRX cycle to monitor one PO. The UE monitors one PO in each DRX cycle.

[0062] In addition, the PO is a set of monitoring occasions for the Physical Downlink Control Channel (PDCCH), and can include multiple time slots (such as subframes or OFDM symbols) where paging DCI can be sent.

[0063] In addition, the DRX cycle represents the period during which the UE detects Paging, PF represents the system frame (Frame) for detecting Paging, PO represents the specific PDCCH monitoring occasions for detecting paging, and i_s represents the index of the PO corresponding to PF. The relevant calculation methods are as follows:

[0064] PF: (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N)

[0065] i_s: i_s = floor(UE_ID / N) mod Ns

[0066] Among them, the above T represents the DRX cycle; there will be a cell-level indication Tc in the system message, and there may also be a UE-level indication Tue in RRC. If there is no indication Tue, then T = Tc; if Tue is indicated, then T = min(Tc, Tue);

[0067] N represents the total number of PFs in T;

[0068] Ns represents the number of POs corresponding to one PF;

[0069] PF_offset represents the offset of PF;

[0070] UE_ID represents 5G-S-TMSI mod 1024. TMSI represents the Temporary Mobile Subscriber Identify of the UE, which can be used to uniquely distinguish different UEs; when the UE does not have a TMSI yet, by default UE_ID = 0.

[0071] It should be noted that the above parameters will all be indicated in the PCCH configuration information (PCCH-config).

[0072] IV. Paging Message

[0073] In a paging message, there is a PagingRecordList carried. This list carries at least 1 and at most maxNrofPageRec PagingRecords. In each PagingRecord, there is a paging identifier (ue_Identity) of the paged UE carried. That is, a paging message can indicate that at most maxNrofPageRec UEs are paged.

[0074] There are two identifiers for the paged UE. One is used to indicate the UE in the idle state during paging, i.e., ng-5G-S-TMSI; the other is used to indicate the UE in the inactive state during paging, i.e., fullI-RNTI. The UE receiving the paging message is in either the idle state or the inactive state.

[0075] Next, in conjunction with the accompanying drawings, the data transmission method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0076] In a first aspect, an embodiment of the present application provides a data transmission method, as Figure 2 shown, the method may include the following steps 201 to 202:

[0077] Step 201: The terminal receives target data through a target resource in a non-connected state.

[0078] Wherein, the target resource includes at least one of a paging resource configured for paging, a specific resource configured for the non-connected state, a first resource associated with the paging resource, and a second resource associated with the specific resource.

[0079] That is, the terminal can receive the target data sent by the network-side device through the paging resource, that is, 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 the specific resource or the first resource associated with the paging resource or the second resource associated with the specific resource in the non-connected state, that is, the network-side device can send the target data to the terminal through the specific resource or the first resource associated with the paging resource or the second resource associated with the specific resource when the terminal is in the non-connected state.

[0080] It can be seen that in the embodiment of the present application, the target data includes the data sent by the network-side device when the terminal is in the non-connected state.

[0081] Step 202: The terminal receives a target transmission related to the target data.

[0082] Wherein, the target transmission includes at least one of data repetition and data retransmission.

[0083] It can be understood that the terminal receiving the target transmission related to the target data means that the terminal receives the target data sent in the way of the target transmission (such as data repetition or data retransmission).

[0084] It should be noted that the difference between data duplicate transmission and data retransmission is as follows: data duplicate transmission is to transmit the same data N times, where N is greater than or equal to 1, that is, data duplicate transmission is N transmissions with a known number of times; data retransmission is to decide whether to perform the next transmission after one transmission. Therefore, although data retransmission may also be multiple transmissions, the number of its transmissions is not known in advance.

[0085] In one embodiment, the above-mentioned target transmission related to the target data may be sent by a network-side device (such as a base station), that is, the network-side device performs at least one of data duplicate transmission and data retransmission on the target data.

[0086] Optionally, the non-connected state includes at least one of the following states:

[0087] 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) and before random access, other non-connected states before random access.

[0088] It can be seen from the above steps 201 to 202 that in the embodiment of the present application, when the terminal is in the non-connected state, it can receive the target data through the target resources, and the target resources include at least one of the paging resources configured for paging, the specific resources configured for the non-connected state, the first resources associated with the paging resources, and the second resources associated with the specific resources; and the terminal can also receive the target transmission related to the target data, where the target transmission includes at least one of data duplicate transmission and data retransmission. It can be seen that in the embodiment of the present application, the network-side device can send the target data to the non-connected state terminal, and for this part of the data, at least one of data duplicate transmission and data retransmission can also be performed, thereby improving the reliability of data transmission. Therefore, the embodiment of the present application provides a data transmission solution between the network-side device and the non-connected state terminal.

[0089] Optionally, step 202 "the terminal receives the target transmission related to the target data" includes:

[0090] The terminal receives the target transmission related to the target data according to the target information;

[0091] Wherein, the target information includes at least one of the following items A-1 to A-5:

[0093] Item A-2: The target number of times for the repeated data transmission

[0094] Item A-3: The first resource for the repeated data transmission

[0095] Item A-4: The beam for the repeated data transmission

[0096] Item A-5: The second resource for the data retransmission

[0097] In one embodiment, the terminal receives the repeated data transmission related to the target data according to at least one of Items A-1 to A-4

[0098] In one embodiment, the terminal receives the data retransmission related to the target data according to Item A-5

[0099] Optionally, the first indication information satisfies at least one of the following:

[0103] The first indication information is carried in the Media Access Control Control Element (MAC CE);

[0104] The first indication information is carried in the Physical Downlink Control Channel (PDCCH) for scheduling data transmission;

[0105] The first indication information is carried in the Downlink Control Information (DCI) for scheduling data transmission;

[0106] The first indication information is carried in the resource of the first data transmission;

[0107] The first indication information is determined according to whether the terminal supports repeated data transmission in the connected state (that is, if the terminal supports repeated data transmission in the connected state, the terminal also supports repeated data transmission in the non-connected state; if the terminal does not support repeated data transmission in the connected state, the terminal also does not support repeated data transmission in the non-connected state);

[0108] The first indication information is determined according to the capabilities of the terminal.

[0109] It can be seen from this that whether the terminal supports data retransmission in the non-connected state can be configured by the network-side device or agreed upon by the protocol.

[0110] Optionally, the target number of times satisfies at least one of the following items B-1 to B-6:

[0111] Item B-1: The target number of times is carried in the system message;

[0143] Item B-6: The target number of times is the common retransmission number.

[0144] In Item B-6, the common retransmission number can be applied to data retransmission in different scenarios; for example, the network-side device configures or the protocol stipulates the common retransmission number for non-connected terminals and the relevant channel signals during the contention-based random access process of the terminal.

[0145] Optionally, the first resource includes consecutive first available resources, where the first available resources satisfy at least one of the following C-1 to C-7:

[0249] Item J-2: When the second timer expires (i.e., timer expire), the terminal receives data retransmission related to the target data; wherein, the second timer starts timing in the next time slot of the time slot where the first data transmission of the target data is located or in a downlink time slot.

[0258] Item K-2: When the terminal has sent feedback information for the target data, the terminal receives data retransmission related to the target data.

[0259] That is, if the terminal sends feedback information for the target data to the network device, then the terminal can also receive subsequent data retransmissions of the target data;

[0260] Item K-3: In the case where the terminal does not send feedback information for the target data, the terminal does not receive data retransmissions related to the target data;

[0262] Item K-4: In the case where the terminal does not send feedback information for the target data, the terminal receives data retransmissions related to the target data;

[0263] That is, if the terminal does not send feedback information for the target data to the network device, then the terminal can also receive subsequent data retransmissions of the target data;

[0264] Item K-5: In the case where the terminal sends feedback information of an acknowledgement of receipt ACK for the target data, the terminal does not receive data retransmissions related to the target data;

[0270] The terminal receives the data repeated transmission related to the target data on a specific physical downlink shared channel (PDSCH).

[0271] It can be seen from this that the network-side device can perform data retransmission for the target data only for a specific PSDCH.

[0272] It should also be noted that different terminals may not support data retransmission in the non-connected state. Therefore, the network-side device can perform data retransmission only for some terminals; or it can perform data retransmission for all terminals.

[0275] Wherein, the target resource includes at least one of a paging resource configured for paging, a specific resource configured for the non-connected state, a first resource associated with the paging resource, and a second resource associated with the specific resource.

[0276] That is, the terminal can receive the target data sent by the network-side device through the paging resource, that is, 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 the specific resource or the first resource associated with the paging resource or the second resource associated with the specific resource in the non-connected state, that is, the network-side device can send the target data to the terminal through the specific resource or the first resource associated with the paging resource or the second resource associated with the specific resource when the terminal is in the non-connected state.

[0277] It can be seen that in the embodiment of the present application, the target data includes the data sent by the network-side device when the terminal is in the non-connected state.

[0278] Step 302: The network-side device sends a target transmission related to the target data.

[0279] Wherein, the target transmission includes at least one of data repetition and data retransmission.

[0280] It should be noted that the difference between data repetition and data retransmission is that data repetition is to repeat the same data N times, N is greater than or equal to 1, that is, data repetition is N transmissions with a known number of times; data retransmission is to decide whether to perform the next transmission after one transmission. Therefore, although data retransmission may also be multiple transmissions, the number of transmissions is not known in advance.

[0281] Optionally, the non-connected state includes at least one of the following states:

[0282] 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 before random access after Radio Resource Control release (RRC release), other non-connected states before random access.

Therefore, the embodiments of the present application provide a data transmission solution between a network-side device and a non-connected state terminal.

[0370] As can be seen from Item H-1, the network device can send at least one of an automatic retransmission and a feedback retransmission of the target data when the terminal is in the disconnected state; in this case, when the terminal is in the disconnected state, it can receive at least one of an automatic retransmission and a feedback retransmission of the target data.

For example, when the terminal is in the disconnected state, the network-side device can perform "automatic retransmission" on the target data X times, and after the terminal enters the connected state, perform "automatic retransmission" Y times; or, when the terminal is in the disconnected state, the network-side device can perform "feedback retransmission" on the target data X times, and after the terminal enters the connected state, perform "feedback retransmission" Y times.

[0373] It should be noted that the feedback retransmission refers to the retransmission based on the reception situation of the actually transmitted data.

[0377] Item L-2: The network-side device sends the data retransmission related to the target data when the second timer times out; wherein, the second timer starts timing in the next time slot or the downlink time slot of the time slot where the first data transmission of the target data is located;

[0378] According to item L-2, the automatic retransmission can start when the second timer fails.

[0379] Item L-3: The network-side device sends the data retransmission related to the target data within the first time window;

[0380] According to item L-3, the automatic retransmission can be performed within the first time window;

[0381] Item L-4: The network-side device sends the data retransmission related to the target data when the first time arrives after the first data transmission of the target data is sent.

[0382] According to item L-4, there can be a time domain offset, and retransmission is performed after the first data transmission of the target data plus this time domain offset.

[0383] Optionally, when the fourth row includes sending a feedback retransmission related to the target data, the network side device sends the feedback retransmission, including at least one of the following P-1 to P-6:

[0384] Item P-1: When the network side device receives feedback information for the target data, the network side device does not send a data retransmission related to the target data;

[0385] That is, if the network side device receives feedback information for the target data sent by the terminal, then the network side device may not send a data retransmission of the target data;

[0386] That is, if the feedback information for the target data sent by the terminal is successfully received, the network side device may not send a data retransmission of the target data.

[0387] Item P-2: When the network side device receives feedback information for the target data, the network side device sends a data retransmission related to the target data;

[0388] That is, if the network side device receives feedback information for the target data sent by the terminal, then the network side device may send a data retransmission of the target data;

[0389] That is, if the feedback information for the target data sent by the terminal is successfully received, the network side device may send a data retransmission of the target data;

[0390] For example, the network side device performs retransmission immediately after receiving HARQ feedback information;

[0391] Or, for example, the network side device performs retransmission within a period of time (such as within a timer / window) after receiving HARQ feedback information;

[0392] Or, for example, the network side device performs retransmission after a certain duration (timer) of receiving HARQ feedback information, such as when the timer times out.

[0393] Item P-3: When the network side device does not receive feedback information for the target data, the network side device does not send a data retransmission related to the target data;

[0394] That is, if the network side device does not receive feedback information for the target data sent by the terminal, then the network side device may not send a data retransmission of the target data;

[0395] Item P-4: When the network-side device does not receive feedback information for the target data, the network-side device sends a data retransmission related to the target data.

[0396] That is, if the network-side device does not receive feedback information for the target data sent by the terminal, then the network-side device can send a data retransmission of the target data.

[0397] That is, if the feedback information for the target data sent by the terminal is not successfully received, the network-side device can send a data retransmission of the target data.

[0398] For example, as long as the network-side device has not received HARQ feedback information within a certain period after sending the target data, it immediately performs a retransmission or triggers a retransmission process.

[0399] Or, for example, as long as the network-side device has not received HARQ feedback information within a certain period after sending the target data, it triggers a retransmission timer (timer); where a retransmission can be performed within this timer, or a retransmission can be performed after this timer times out.

[0400] Item P-5: When the network-side device receives feedback information of an acknowledged reception ACK for the target data, the network-side device does not send a data retransmission related to the target data.

[0401] That is, if the network-side device receives feedback information for the target data sent by the terminal, and this feedback information belongs to the feedback information of ACK, then the network-side device can not send a data retransmission of the target data.

[0402] Item P-6: When the network-side device receives feedback information of a non-acknowledged reception NACK for the target data, the network-side device sends a data retransmission related to the target data.

[0403] That is, if the network-side device receives feedback information for the target data sent by the terminal, and this feedback information belongs to the feedback information of NACK, then the network-side device can send a data retransmission of the target data.

[0404] For example, the network-side device immediately performs a retransmission after receiving a HARQ NACK feedback.

[0405] Or, for example, the network-side device performs a retransmission within a certain period (e.g., within a timer / window) after receiving a HARQ NACK feedback.

[0406] Alternatively, for example, the network - side device performs re - transmission only after receiving a HARQ NACK feedback for a certain duration (timer), such as when the timer times out.

[0407] Optionally, in the case where the target transmission includes the data re - transmission, the network - side device sends the data re - transmission related to the target data, including:

[0408] The network - side device sends the data re - transmission related to the target data on a specific PDSCH.

[0409] It can be seen therefrom that the network - side device can perform data re - transmission on the target data only for a specific PSDCH.

[0410] It should also be noted that the situations of whether different terminals support data re - transmission in the non - connected state may not be the same. Therefore, the network - side device can perform data re - transmission only for some terminals; or it can perform data re - transmission for all terminals.

[0411] That is, the granularity of supporting data repetition (repetition) can include at least one of the following:

[0412] Only some terminals perform data re - transmission,

[0413] All terminals perform data re - transmission;

[0414] Perform data re - transmission for PDSCH. For example, the data transmission on a specific PDSCH needs to be re - transmitted.

[0416] Based on UE capabilities;

[0417] Based on the indication information in DCI;

[0418] Based on RRC configuration;
