[0195] In some embodiments, Mobile Originated Early Data Transmission (MO-EDT) is a mechanism for a mobile terminal to send data to the core network. Through MO-EDT, the mobile terminal can transmit data to the core network for further processing and distribution.

[0196] In some embodiments, MO-EDT allows selective uplink data transmission followed by downlink data transmission during the random access procedure.

[0197] In some embodiments, MO-EDT is triggered when upper layers have requested the establishment or resumption of an RRC connection for mobile originated data (i.e., not signaling or SMS) and the uplink data size is less than or equal to the TB size indicated in the system information. MO-EDT is not used for data on the control plane when using user plane cellular IoT (CIoT) Evolved Packet System (EPS) / 5G System (5GS) optimization.

[0198] In some embodiments, MO-EDT is only applicable to narrowband low complexity (BL) terminals, terminals in enhanced coverage, and narrowband Internet of Things (NB-IoT) terminals.

[0199] In some embodiments, in the control plane CIoT EPS / 5GS optimized MO-EDT, the control plane CIoT EPS optimized MO-EDT defined in some embodiments and the controller plane CIoT 5GS optimized MO-EDT defined in some embodiments are characterized as follows:

[0200] Sending uplink user data in a Non-Access Stratum (NAS) message concatenated with an Uplink (UL) RRC Early Data Request message on a Common Control Channel (CCCH);

[0201] Downlink user data is optionally transmitted in a NAS message concatenated with an RRC Early Data Complete message on the CCCH.

[0202] The state RRC CONNECTED is not switched to.

[0203] In some embodiments, the MO-EDT process for control plane CIoT EPS optimization and control plane CIoT 5GS optimization is shown in Figures 2A and 2B, respectively. Figure 2A is an example schematic diagram of a control plane CIoT EPS optimized MO-EDT provided by an embodiment of the present disclosure, and Figure 2B is an example schematic diagram of a control plane CIoT 5GS optimized MO-EDT provided by an embodiment of the present disclosure, including:

[0204] 0. Following a connection establishment request for mobile originated data from upper layers, the terminal initiates the MO-EDT procedure and selects a random access preamble configured for EDT.

[0205] 1. The terminal sends an RRC Early Data Request message for connecting user data on CCCH. For EPS enabled in the cell, or for 5GS, the terminal can instruct the Assistance (AS) to release the assistance information.

[0206] 2. For EPS, the eNB initiates the S1 Application Protocol (S1-AP) Initial Terminal Message procedure to forward NAS messages and establish an S1 connection. For 5GS, the ng eNB initiates the ng-AP Initial Terminal Message procedure to forward NAS messages. In this procedure, the eNB (evolved Node B) in an (ng-)LTE (Long-Term Evolution) network can indicate that the connection is triggered for EDT.

[0207] 3. For EPS, the MME requests the Serving GateWay (S-GW) to reactivate the EPS bearer for the terminal. For 5GS, the AMF determines the PDU session contained in the NAS message.

[0208] 4. For EPS, MME sends uplink data to S-GW. For 5GS, AMF sends PDU session ID and uplink data to SMF, and SMF forwards the uplink data to UPF.

[0209] 5. For EPS, if downlink data is available, the S-GW sends the downlink data to the Mobility Management Entity (MME). For 5GS, if downlink information is available, the UPF forwards the downlink information to the SMF, and the SFM sends the downlink information to the AMF.

[0210] 6. If downlink data is received from the S-GW or SMF, the MME or AMF forwards the data to the eNB or ng eNB via the DL NAS Transfer procedure and may also indicate whether further data is expected. Otherwise, the MME or AMF may trigger the Connection Establishment Indication procedure and also indicate whether further data is expected.

[0211] 7. If no further data is expected, the (ng-)eNB may send an RRC Early Data Complete message on CCCH to keep the terminal in RRC_IDLE. If downlink data is received in step 6, they are concatenated in the RRC Early Data Complete message.

[0212] 8. For EPS, the S1 connection is released and the EPS bearer is deactivated. For 5GS, the AN release procedure is initiated.

[0213] NOTE 1: If the MME / AMF or (ng-)eNB decides to move the terminal in RRC_CONNECTED mode, an RRCConnectionSetup message is sent in step 7 to fall back to the legacy RRC connection establishment procedure; the (ng-)eNB shall discard the zero-length NAS PDU received in the RRCConnectionSetupComplete message.

[0214] NOTE 2: If neither RRC Early Data Complete nor RRC Connection Setup is received in response to an RRC Early Data Request, the terminal considers that the UL data transmission is unsuccessful.

[0215] In some embodiments, in MO-EDT for user plane CIoT EPS / 5GS optimization, features of MO-EDT for user plane CIoT EPS optimization defined in some embodiments and MO-EDT for user plane CIoT 5GS optimization defined in some embodiments are as follows:

[0216] The Next Hop Chaining Count has been provided to the terminal in the RRC Connection Release message with a suspend indication;

[0217] Uplink user data is transmitted on the DTCH multiplexed with the UL RRC Connection Resume Request message on the CCCH;

[0218] Downlink user data is optionally transmitted on the DTCH multiplexed with the DL RRC Connection Release message on the DCCH;

[0219] The Short Resume MAC-I is reused as the authentication token for the RRC Connection Resume Request message and is calculated using the integrity key from the previous connection;

[0220] User data in uplink and downlink is encrypted. The key is derived using the Next Hop Chaining Count hopping configuration provided in the RRC Connection Release message of the previous RRC connection;

[0221] The RRC Connection Release message is integrity protected and encrypted using the newly derived key;

[0222] No transition to the RRC connected state CONNECTED.

[0223] In some embodiments, FIG2C is a schematic diagram illustrating an example of a MO-EDT process for user plane CIoT EPS optimization provided by an embodiment of the present disclosure, including:

[0224] 0. Following a connection resumption request for mobile originated data from upper layers, the terminal initiates the MO-EDT procedure and selects a random access preamble configured for EDT.

[0225] 1. The terminal sends an RRC Connection Resume Request to the eNB, including its resume identifier ResumeID, establishment cause, and authentication token. The terminal resumes all signaling radio bearers (SRBs) and data radio bearers (DRBs), uses the Next Hop Chaining Count provided in the RRC Connection Release message of the previous RRC connection to derive new security keys, and re-establishes AS security. User data is encrypted and transmitted on the Dedicated Traffic CHannel (DTCH), which is multiplexed with the RRC Connection Resume Request message on the CCCH. If enabled in the cell, the terminal can instruct the AS to release auxiliary information.

[0226] 2. The eNB initiates the S1-AP context restoration procedure to restore the S1 connection and reactivate the S1-U bearer.

[0227] 3. The MME requests the S-GW to reactivate the S1-U bearer for the terminal.

[0228] 4. The MME confirms the terminal context recovery to the eNB.

[0229] 5. Uplink data is transmitted to the S-GW.

[0230] 6. If downlink data is available, the S-GW sends the downlink data to the eNB.

[0231] 7. If no further data is expected, the eNB may initiate suspension of the S1 connection and deactivation of the S1-U bearer.

[0232] 8. The eNB sends an RRC Connection Release message to keep the terminal in RRC_IDLE. This message includes the Release Cause (set to RRC Suspend), the resumeID, the Next Hop Chaining Count, and the DRBC Continue ROHC, which are stored by the terminal. If downlink data is received in step 6, it is encrypted and sent on the DTCH multiplexed with the RRC Connection Release message on the DCCH. The process ends with the receipt of Hybrid Automatic Repeat reQuest (HARQ) feedback (ARQ) confirming the successful DL transmission.

[0233] In some embodiments, some EDT procedures are based on random access procedures. To send uplink data, the terminal must go through at least four steps:

[0234] 1. Send Msg1;

[0235] 2. Receive Msg2;

[0236] 3. Send Msg3;

[0237] 4. Receive Msg4.

[0238] In some embodiments, 3GPP is studying the use of OCC (orthogonal cover code) to increase uplink capacity. However, this uplink capacity increase can only increase the capacity of Msg1 and Msg3. Msg2 and Msg4 will become bottlenecks that restrict system capacity. To solve this problem, 3GPP is studying an EDT method without Msg1 / Msg2, that is, only Msg3 and Msg4, and calls it Msg1-Less EDT. A key focus of Msg3 research is how to directly send Msg3 without Msg1 and Msg2. The focus of Msg4 research is how to efficiently transmit Msg4 to increase Msg4 capacity.

[0239] A PDCCH monitoring method, apparatus, device, and storage medium provided by embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0240] FIG3A is an interactive diagram of a PDCCH monitoring method provided by an embodiment of the present disclosure. As shown in FIG3A , the method may include the following steps:

[0341] The specific RNTI is determined according to the ninth constant, the OCC resource number, Z and the DMRS resource number, wherein the OCC resource number is used to indicate the OCC resource selected for sending Msg3, the DMRS resource number is used to indicate the DMRS resource selected for sending Msg3, the OCC resource number is greater than or equal to 0 and less than Z, Z is a natural number, the DMRS resource number is greater than or equal to 0 and less than P, and P is a natural number.

[0342] Furthermore, in one embodiment of the present disclosure, the ninth constant may, for example, refer to a constant corresponding to determining a specific RNTI based on the OCC resource, Z, and the DMRS resource selected by the terminal when sending Msg3. The ninth constant is used to distinguish it from the remaining constants. For example, the ninth constant may be the same as or different from the other constants. This embodiment of the present disclosure is not limited in this regard.

[0343] In some embodiments, the terminal may number the DMRS resources on a PO, and different DMRS resources may correspond to different RNTIs. The ninth constant may be, for example, 1, the OCC resource number sent by the PO may be, for example, OCC_id, the DMRS resource number sent by the PO may be, for example, DMRS_id, and the specific RNTI may be determined, for example, by formula (9): RNTI = 1 + OCC_id + Z * DMRS_id (9)

[0344] Wherein, Z is a natural number such as 1, 2...6, 7, 8, 9, 10, etc. P is a natural number such as 1, 2...6, 7, 8, 9, 10, etc.

[0345] In one embodiment of the present disclosure, the PDCCH search space for receiving a response by the terminal is configured separately. For example, the PDCCH search space for receiving a response by the terminal may be different from the PDCCH search space for receiving a random access RAR.

[0346] For example, in one embodiment of the present disclosure, determining a specific RNTI according to a DMRS resource selected for sending Msg3 includes:

[0347] The specific RNTI is determined according to the tenth constant, the DMRS resource number, P and the OCC resource number, wherein the OCC resource number is used to indicate the OCC resource selected for sending Msg3, the DMRS resource number is used to indicate the DMRS resource selected for sending Msg3, the OCC resource number is greater than or equal to 0 and less than Z, Z is a natural number, the DMRS resource number is greater than or equal to 0 and less than P, and P is a natural number.

[0348] Furthermore, in one embodiment of the present disclosure, the tenth constant may, for example, refer to a constant corresponding to determining a specific RNTI based on the OCC resource, P, and DMRS resource selected by the terminal when sending Msg3. The ninth constant in the tenth constant is used to distinguish it from the remaining constants. The tenth constant may, for example, be the same as or different from the other constants. This embodiment of the present disclosure is not limited in this regard.

[0349] In some embodiments, the terminal may number the DMRS resources on a PO, and different DMRS resources may correspond to different RNTIs. The tenth constant may be, for example, 1, the OCC resource number sent by the PO may be, for example, OCC_id, the DMRS resource number sent by the PO may be, for example, DMRS_id, and the specific RNTI may be determined, for example, by formula (10): RNTI = 1 + DMRS_id + P * OCC_id (10)

[0350] Wherein, Z is a natural number such as 1, 2...6, 7, 8, 9, 10, etc. P is a natural number such as 1, 2...6, 7, 8, 9, 10, etc.

[0351] In one embodiment of the present disclosure, the PDCCH search space for receiving a response by the terminal is configured separately. For example, the PDCCH search space for receiving a response by the terminal may be different from the PDCCH search space for receiving a random access RAR.

[0352] In one embodiment of the present disclosure, the method further includes:

[0353] A first configuration sent by a network device is received, where the first configuration is used to indicate a specific RNTI.

[0354] For example, in one embodiment of the present disclosure, when configuring contention resources for sending EDT msg3, the network device may configure an RNTI value to be used, and the terminal monitors the PDCCH identified by the specific RNTI.

[0355] In one embodiment of the present disclosure, receiving a first configuration sent by a network device includes:

[0356] A second configuration sent by the network device is received, wherein the second configuration is used to configure the contention resource sent by the EDT msg3, and the second configuration includes the first configuration.

[0357] In one embodiment of the present disclosure, the first configuration is a configuration of the Per coverage extended CE level.

[0358] In one embodiment of the present disclosure, the method further includes:

[0359] A third configuration sent by the network device is received, wherein the third configuration is used to configure contention resources sent by EDT msg3, and the third configuration includes a specially configured PDCCH search space search space, which is the PDCCH search space to be monitored by the terminal in the response window.

[0360] For example, in one embodiment of the present disclosure, the network device configures a dedicated PDCCH search space in the contention resource configuration for sending EDT msg3. The PDCCH search space is the PDCCH search space that the terminal monitors in the response window.

[0361] In one embodiment of the present disclosure, the specially configured PDCCH search space is configured per coverage extension CE level. In this way, when the specific RNTIs determined by the terminal are the same for different coverage extension CE levels, the RNTI conflict problem can be resolved by receiving the specific RNTIs in different PDCCH search spaces.

[0362] In one embodiment of the present disclosure, the method further includes:

[0363] The frequency domain offset value of the coverage extension CE level sent by the receiving network device is received. Therefore, the terminal can take the f_id offset value into consideration when determining the RNTI, thereby avoiding the situation where the same RNTI is determined for different coverage extension CE levels, thereby causing RNTI conflicts.

[0364] In one embodiment of the present disclosure, the method further includes:

[0365] Receive the RNTI offset for the coverage extension CE level sent by the network device. Therefore, when determining the RNTI, the terminal adds the configured RNTI offset to the RNTI value for different coverage extension CE levels as the final RNTI value, thereby avoiding the situation where the same RNTI is determined for different coverage extension CE levels, thereby causing RNTI conflicts.

[0366] In some embodiments, steps S3101 to S3102 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0379] FIG6A is a flow chart of a PDCCH monitoring method according to an embodiment of the present disclosure. As shown in FIG6A , the embodiment of the present disclosure relates to a PDCCH monitoring method, which includes:

[0380] In step S6101, after the user equipment (UE) sends an Early Data Transmission (EDT) message (Msg) 3 based on contention resources, the UE monitors the Physical Downlink Control Channel (PDCCH) identified by a specific Radio Network Temporary Indentifier (RNTI) within a response window.

[0381] In some embodiments, the base station may schedule the response message of Msg3 and / or the retransmission of Msg3 through the RNTI.

[0382] In some embodiments, the specific RNTI may be calculated by the UE itself.

[0383] In some embodiments, the specific RNTI may be calculated by taking into account the time domain location of the resource selected by the UE to send Msg3.

[0384] In some embodiments, the UE may number all time domain positions of paging occasions (POs) transmitted within the response window, and different time domain positions correspond to different RNTIs. For example, RNTI = 1 + t_id + offset. 0 <= t_id < X. t_id is the time domain position number of the PO transmission. X takes natural numbers such as 2, 3, 5, 6, 8, 10, 20, 30, 40, 50, 60, etc. Offset is equal to 0, 1, 2, 3, etc. In particular, the offset value Offset = 10 * 6, for example, when the PDCCH search space for receiving the response by the UE is the same as the PDCCH search space for receiving the random access response (RAR).

[0385] In some embodiments, when calculating the specific RNTI, the frequency domain position of the resource selected by the UE for transmitting Msg3 may be considered.

[0386] In some embodiments, the UE may number all frequency domain positions of POs transmitted within the response window, and different frequency domain positions correspond to different RNTIs. For example, RNTI = 1 + t_id + X * f_id. 0 <= f_id < Y. f_id is the frequency domain position number of the PO transmission. Y takes natural numbers such as 1, 2...6, 7, 8, 9, 10, etc. Offset is equal to 0, 1, 2, 3, etc. In particular, Offset = 10 * 6, for example, when the PDCCH search space for receiving the response by the UE is the same as the PDCCH search space for receiving the RAR of random access.

[0387] In some embodiments, when calculating the specific RNTI, the orthogonal cover code (OCC) resource selected by the UE for transmitting Msg3 may be considered.

[0388] In some embodiments, the UE may number the OCC resources on a PO, and different OCC resources correspond to different RNTIs. For example, RNTI = 1 + t_id + X * f_id + X * Y * OCC_id + offset. 0 <= OCC_id < Z. OCC_id is the number of the OCC resource sent by the PO. Z takes natural numbers such as 1, 2...6, 7, 8, 9, 10, etc. Offset is equal to 0, 1, 2, 3, etc. In particular, Offset = 10 * 6, for example, when the PDCCH search Space for the UE to receive the response is the same as the PDCCH search Space for receiving the RAR of random access.

[0389] In some embodiments, the UE may number the OCC resources on a PO, and different OCC resources correspond to different RNTIs. For example, RNTI = 1 + OCC_id. This calculation method is applicable when the PDCCH search Space for the UE to receive the response is configured separately, that is, different from the PDCCH search Space for receiving the RAR of random access.

[0390] In some embodiments, the specific RNTI calculation considers the demodulation reference signal (Dedicated Reference Signal, DMRS) resource selected by the UE when sending Msg3.

[0391] In some embodiments, the UE may number the DMRS resources on a PO, and different DMRS resources correspond to different RNTIs. For example, RNTI = 1 + t_id + X * f_id + X * Y * DMRS_id + offset. 0 <= DMRS_id < P. DMRS_id is the number of the DMRS resource sent by the PO. P takes natural numbers such as 1, 2...6, 7, 8, 9, 10, etc. Offset is equal to 0, 1, 2, 3, etc. In particular, Offset = 10 * 6, for example, when the PDCCH search Space for the UE to receive the response is the same as the PDCCH search Space for receiving the RAR of random access.

[0392] In some embodiments, the UE may number the DMRS resources on a PO, and different DMRS resources correspond to different RNTIs. For example, RNTI = 1 + t_id + X * f_id + X * Y * OCC_id + X * Y * Z * DMRS_id + offset. 0 <= DMRS_id < P. DMRS_id is the number of the DMRS resource sent by the PO. P takes natural numbers such as 1, 2... 6, 7, 8, 9, 10, etc. Offset is equal to 0, 1, 2, 3, etc. In particular, Offset = 10 * 6, for example, when the PDCCH search space for the UE to receive the response is the same as the PDCCH search space for receiving the RAR of random access.

[0393] In some embodiments, the UE may number the DMRS resources on a PO, and different DMRS resources correspond to different RNTIs. For example, RNTI = 1 + t_id + X * f_id + X * Y * DMRS_id + X * Y * P * OCC_id + offset. 0 <= DMRS_id < P. DMRS_id is the number of the DMRS resource sent by the PO. P takes natural numbers such as 1, 2... 6, 7, 8, 9, 10, etc. Offset is equal to 0, 1, 2, 3, etc. In particular, Offset = 10 * 6, for example, when the PDCCH search space for the UE to receive the response is the same as the PDCCH search space for receiving the RAR of random access. [[ID=##]] [[ID=##]]

[0394] In some embodiments, the UE may number the DMRS resources on a PO, and different DMRS resources correspond to different RNTIs. For example, RNTI = 1 + DMRS_id. 0 <= DMRS_id < P. DMRS_id is the number of the DMRS resource sent by the PO. P takes natural numbers such as 1, 2... 6, 7, 8, 9, 10, etc. This calculation method is applicable when the PDCCH search space for the UE to receive the response is configured separately, that is, different from the PDCCH search space for receiving the RAR of random access.

[0395] In some embodiments, the UE may number the DMRS resources on a PO, and different DMRS resources correspond to different RNTIs. For example, RNTI = 1 + OCC_id + Z * DMRS_id. 0 <= DMRS_id < P. DMRS_id is the number of the DMRS resource sent by the PO. P takes natural numbers such as 1, 2...6, 7, 8, 9, 10, etc. This calculation method is applicable to the case where the PDCCH search space for the UE to receive the response is configured separately, that is, different from the PDCCH search space for receiving the RAR of random access.

[0396] In some embodiments, the UE may number the DMRS resources on a PO, and different DMRS resources correspond to different RNTIs. For example, RNTI = 1 + DMRS_id + P * OCC_id. 0 <= DMRS_id < P. DMRS_id is the number of the DMRS resource sent by the PO. P takes natural numbers such as 1, 2...6, 7, 8, 9, 10, etc. This calculation method is applicable to the case where the PDCCH search space for the UE to receive the response is configured separately, that is, different from the PDCCH search space for receiving the RAR of random access.

[0397] In some embodiments, the specific RNTI may be network-configured.

[0398] In some embodiments, when the network configures the contention resources for EDT msg3 transmission, it may configure the RNTI value to be used. The UE listens to the PDCCH identified by this RNTI.

[0399] In some embodiments, the specific RNTI may be configured per coverage extension CE level.

[0400] In some embodiments, the network may configure a dedicated PDCCH search space in the contention resource configuration for EDT msg3 transmission. This PDCCH search space is the PDCCH search space that the UE needs to listen to in the response window.

[0401] In some embodiments, the PDCCH search space may be configured per coverage extension CE level.

[0402] In some embodiments, in this way, when the RNTIs calculated by UEs of different coverage extension CE levels are the same, the RNTI conflict problem can be solved by receiving the RNTIs in different PDCCH search spaces.

[0403] In some embodiments, the network may indicate f_id offset values ​​for different coverage extension CE levels.

[0404] In some embodiments, the UE may take the f_id offset into account when calculating the RNTI to avoid RNTI conflicts caused by calculating the same RNTI for different coverage extension CE levels.

[0405] In some embodiments, the network indicates RNTI offsets for different coverage extension CE levels.

[0406] In some embodiments, when calculating RNTI, the UE adds the configured RNTI offset to the RNTI value for different coverage extension CE levels as the final calculated RNTI value, thereby avoiding RNTI conflicts caused by calculating the same RNTI for different coverage extension CE levels.
