[0166] When Early Data Transmission (EDT) is based on a random access process, for a terminal device to send an uplink data, it must go through at least four steps: sending Message 1 (Msg1), receiving Message 2 (Msg2), sending Message 3 (Msg3), and receiving Message 4 (Msg4).

[0167] Currently, the 3rd Generation Partnership Project (3GPP) is researching ways to improve uplink capacity through Orthogonal Cover Code (OCC). However, the uplink capacity improvement can only enhance the capacity of Msg1 and Msg3. Msg2 and Msg4 will become the bottleneck restricting the system capacity. To solve this problem, 3GPP is researching the Early Data Transmission (EDT) method without Msg1 / Msg2 data, that is, only Msg3 and Msg4. One research focus for Msg3 is how to directly send Msg3 without Msg1 and Msg2, and the research focus for Msg4 is how to efficiently transmit Msg4 to improve the capacity of Msg4.

[0168] Regarding under what circumstances the terminal device can initiate Msg1-Less EDT is a key point of research for 3GPP.

[0175] In some embodiments, the first condition may be, for example, a specified condition or a configured condition. Among them, the specified condition may be preset by a protocol or set by a terminal device. Among them, the configured condition may be obtained by configuration by a network device.

The present disclosure does not limit this.

[0184] In some embodiments, terms such as "EDT", "early data transmission", and "Early Data Transmission" may be interchangeable with each other.

[0185] In some embodiments, terms such as "CIOT", "cellular Internet of Things", and "Cellular Internet of Things" may be interchangeable with each other.

[0186] In some embodiments, the terms "RRC", "Radio Resource Control", "Radio Resource Control" and the like may be used interchangeably.

[0192] In some embodiments, terms such as "5GS", "5G network element", and "5G System" can be used interchangeably.

[0193] In some embodiments, when the network device performs Msg1-Less EDT resource configuration through RRC dedicated signaling, the terminal device 101 can determine whether a valid timing alignment value is set; when the terminal device is set with a valid timing alignment value, it is determined that the first condition is met.

[0194] The terminal device is set with a valid timing alignment value, which may refer to any of the following situations: the terminal device is not configured with a timing alignment value; the terminal device is configured with a timing alignment value and the timing alignment timer (TimeAlignment Timer, TAT) is in a running state. In the case where the terminal device is not configured with a timing alignment value, the terminal device may be set with a default timing alignment value, and the default timing alignment value is always in a valid state.

[0195] In some embodiments, when the network device configures Msg1-Less EDT resources through RRC dedicated signaling, the terminal device 101 may determine whether it has received the configuration information of the timer TAT for timing alignment of data early transmission Msg1-Less EDT from the network device; if it has received the configuration information, start the TAT timer; and determine that the terminal device has a valid timing alignment value.

[0196] Among them, when the terminal device receives the configuration information of the timer TAT for timing alignment of Msg1-Less EDT from the network device, it may store the current reference signal received power (RSRP) value of the serving cell to which the terminal device belongs.

[0197] In some embodiments, when the network device configures Msg1-Less EDT resources through RRC dedicated signaling, the terminal device 101 may determine whether it has received a timing advance command MAC control element or a timing advance adjustment indicated by a physical downlink control channel (PDCCH); if it has received a timing advance command MAC control element or a timing advance adjustment indicated by a physical downlink control channel PDCCH, restart the timing alignment timer TAT; and determine that the terminal device has a valid timing alignment value.

[0198] Among them, when the terminal device restarts the timing alignment timer TAT, it may indicate the timing advance adjustment to the RRC layer through the media access control (MAC) layer of the terminal device. Among them, when the RRC layer of the terminal device receives the timing advance adjustment indicated by the MAC layer of the terminal device, it may replace the stored serving cell reference signal received power RSRP value with the current RSRP value of the serving cell to which the terminal device belongs.

[0199] In some embodiments, when the network device configures Msg1-Less EDT resources through RRC dedicated signaling, the terminal device 101 may restart the timing alignment timer TAT after completing the random access procedure; and determine that the terminal device has a valid timing alignment value.

[0200] Among them, when the terminal device 101 is running the TAT timer, it can determine whether it has received the configuration information for releasing the TAT timer configuration for the data early transmission Msg1-Less EDT of message-less 1 from the network device; when receiving this configuration information, it stops the TAT timer.

[0201] In some embodiments, when the network device configures Msg1-Less EDT resources through RRC dedicated signaling, the terminal device 101 can, when the random access procedure is not completed and it receives a temporary N TA , set N TA to this temporary N TA .

[0202] In some embodiments, terms such as "TAT", "timing alignment timer", and "Time Alignment Timer" can be replaced with each other.

[0203] In some embodiments, terms such as "RSRP", "reference signal received power", and "ReferenceSignalReceivedPower" can be replaced with each other.

[0204] In some embodiments, terms such as "MAC", "media access control", and "Media Access Control" can be replaced with each other.

[0205] In some embodiments, when the configured resource is a non-competitive resource for Msg1-Less EDT, the terminal device 101 can obtain the difference between the current reference signal received power RSRP value of the serving cell to which the terminal device belongs and the stored RSRP value of the serving cell; when the difference is less than the specified RSRP change threshold for the data early transmission Msg1-Less EDT of message-less 1, it is determined that the first condition is satisfied.

[0206] Among them, the difference between the current RSRP value of the serving cell to which the terminal device belongs and the stored RSRP value of the serving cell can be positive or negative. When the difference is positive, the difference is an increase amount. That is to say, when the increase amount of the current RSRP value of the serving cell to which the terminal device belongs relative to the stored RSRP value of the serving cell is less than the specified RSRP change threshold for Msg1-Less EDT, it is determined that the first condition is satisfied. When the difference is negative, the difference is a decrease amount. That is to say, when the decrease amount of the current RSRP value of the serving cell to which the terminal device belongs relative to the stored RSRP value of the serving cell is less than the specified RSRP change threshold for Msg1-Less EDT, it is determined that the first condition is satisfied.

[0207] In some embodiments, when the configured resource is a non-competitive resource or a competitive resource for Msg1-Less EDT, the terminal device 101 may obtain the request purpose and the RRC connection reason of the RRC connection establishment request or the RRC connection resume request; when the request purpose is for the terminal device to initiate a call and the RRC connection reason is a specified reason, it is determined that the first condition is satisfied.

[0208] Wherein, the specified reason may include at least one of the following: data initiated by the terminal device (mo-data); abnormal data initiated by the terminal device (mo-exception data); delay tolerant access.

[0209] In some embodiments, when the configured resource is a non-competitive resource or a competitive resource for Msg1-Less EDT, the terminal device 101 may determine, for an RRC connection resume request, whether it has received an RRC connection release message with a suspend indication; when it has received an RRC connection release message with a suspend indication and the RRC connection release message carries a valid next hop chaining count, it is determined that the first condition is satisfied.

[0210] Wherein, the next hop chaining count may refer to the Next Hop Chaining Counter parameter (NCC) for next hop access key derivation. This parameter may be carried in the 5G Access-stratum security context for 3GPP access. Among them, the 5G Access-stratum security context may include at least one of the following parameters: the access stratum AS-level encryption key and its identifier, the next hop parameter (NH), the Next Hop Chaining Counter parameter (NCC) for next hop access key derivation, the identifier of the selected AS-level encryption algorithm, the UE security capabilities and the network side's UP security policy, the UP security activation status, and the counter for replay protection. For a detailed description of the next hop chaining count, reference may be made to the description in the protocol and no further detailed description will be provided here.

[0211] In some embodiments, when the configured resource is a contention-free resource or a contention resource for Msg1-Less EDT, the terminal device 101 may transmit the Msg1-Less CP EDT in advance for the data without Msg1 on the control plane, and determine whether the size of the media access control (MAC) packet data unit (PDU) containing the EDT msg3 is less than or equal to the size of the maximum allowable transport block size (TBS); if the size of the MAC PDU containing the EDT msg3 is less than or equal to the size of the TBS, it is determined that the first condition is met.

[0212] In some embodiments, the terminal device 101 may perform early data transmission for the data without Msg1 on the contention-based shared resource (CBSMsg1-Less EDT), and determine whether the broadcast message of the network device contains first indication information; the first indication information indicates that the terminal device is allowed to send data and / or signaling using the configured resource; if the broadcast message contains the first indication information, it is determined that the first condition is met.

[0213] Wherein, the first indication information may include at least one of the following: an indication of enabling / supporting CBS Msg1-Less EDT; resource configuration information of CBS Msg1-Less EDT.

[0214] In some embodiments, the terminal device 101 may perform early data transmission for the data without Msg1 on the contention-free shared resource (CFSMsg1-Less EDT), and the terminal device is configured with valid CFS Msg1-Less EDT configuration information; it is determined that the first condition is met.

[0215] In some embodiments, the terminal device 101 may perform early data transmission for the data without Msg1 on the contention-free dedicated resource (CFD Msg1-Less EDT), and the terminal device is configured with valid CFD Msg1-Less EDT configuration information; it is determined that the first condition is met.

[0216] In some embodiments, terms such as "CBS", "contention based shared resource", and "contention based shared resource" can be used interchangeably.

[0217] In some embodiments, terms such as "CFS", "contention free shared resource", and "contention free shared resource" can be used interchangeably.

[0218] In some embodiments, terms such as "CFD", "contention free dedicated resource", and "contention free dedicated resource" can be used interchangeably.

[0219] Step S2102, when the first condition is met, the terminal device uses the configured resources to send data and / or signaling to the network device.

[0220] In some embodiments, the configured resources can be resources for Msg1-Less Early Data Transmission (Msg1-Less EDT). Among them, these resources can be used for sending Msg3 of Msg1-Less EDT. Here, the data and / or signaling can be, for example, Msg3.

[0221] Among them, the resources for Msg1-Less EDT can be competitive resources or non-competitive resources. For non-competitive resources, they can be preconfigured uplink resources (PUR) configured for the OCC resources of the terminal device. For competitive resources, no unique uplink resource / demodulation reference signal (DMRS) is configured for the terminal device. When using competitive resources, the terminal device can select an OCC / DMRS resource from the OCC / DMRS resource pool.

[0222] Among them, for competitive resources, the network device 102 can send them to the terminal device 101 through system messages or dedicated signaling. For non-competitive resources, the network device 102 can send them to the terminal device 101 through dedicated signaling.

[0223] Among them, msg3 of Msg1-Less EDT may include one or more of the following: a Radio Resource Control (RRC) early data request message for optimizing the control plane Cellular Internet of Things (CIoT) function (UL RRC Early Data Request message for control plane CIoT EPS / 5GS optimization); uplink (UL) user data transmitted on a dedicated transport channel (DTCH) for optimizing the user plane CIoT function and multiplexed with a UL RRC connection request message on a common control channel (CCCH) (Uplink user data transmitted on DTCH for user plane CIoT EPS / 5GS optimization multiplexed with UL RRC Connection Resume Request message on CCCH). The present disclosure does not limit this.

[0224] In this embodiment, the terminal device receives an upper layer request and determines whether the first condition is satisfied; if the first condition is satisfied, the terminal device uses the configured resources to send data and / or signaling to the network device; thus, it can be determined that when the terminal device receives an upper layer request and the first condition is satisfied, the configured resources are used to send data and / or signaling, improving the transmission efficiency of the data and / or signaling.

[0228] In some embodiments, the upper layer request may be an upper layer Radio Resource Control (RRC) connection establishment request or an RRC connection resume request. The configured resources may be resources for early data transmission without message 1 (Msg1-Less Early Data Transmission, Msg1-Less EDT). Among them, this resource may be used for sending Msg3 of Msg1-Less EDT. Among them, the data and / or signaling here may be Msg3, for example.

[0229] Among them, the resources for Msg1-Less EDT can be competitive resources or non-competitive resources. For non-competitive resources, they can be preconfigured uplink resources (PUR) configured for the OCC resources of the terminal device. For competitive resources, no unique uplink resource / demodulation reference signal (DMRS) is configured for the terminal device. When using competitive resources, the terminal device can select an OCC / DMRS resource from the OCC / DMRS resource pool.

[0230] Among them, for competitive resources, the network device 102 can send them to the terminal device 101 through system messages or dedicated signaling. For non-competitive resources, the network device 102 can send them to the terminal device 101 through dedicated signaling.

When the difference is negative, the difference is a decrease amount.

[0311] In the present embodiment, the terminal device determines whether it receives an RRC connection release message with a suspension indication by receiving an RRC connection resume request from the upper layer; if it receives an RRC connection release message with a suspension indication and the RRC connection release message carries a valid next-hop chain value, it is determined that the first condition is satisfied; if the first condition is satisfied, configured resources are used to send data and / or signaling. Thus, it can be determined that when the terminal device receives an RRC connection resume request from the upper layer and the first condition is satisfied, configured resources are used to send data and / or signaling, improving the transmission efficiency of the data and / or signaling.

[0312] Figure 3H is a flowchart of a method for sending data and / or signaling based on configured resources according to an embodiment of the present disclosure. As Figure 3H shown, the embodiments of the present disclosure relate to a method for sending data and / or signaling based on configured resources, which is used for a terminal device 101. The method includes:

[0313] Step S3801: When receiving an upper layer request, for the early transmission of data without Msg1 on the control plane (Msg1-LessCP EDT), determine whether the size of the media access control (MAC) protocol data unit (PDU) containing EDT msg3 is less than or equal to the size of the maximum allowed transport block size (TBS).

[0314] Step S3802: If the size of the MAC PDU containing EDT msg3 is less than or equal to the size of the TBS, it is determined that the first condition is satisfied.

[0315] Step S3803: If the first condition is satisfied, use the configured resources to send data and / or signaling.

[0316] In some embodiments, the upper layer request can be an RRC connection establishment request or an RRC connection resume request from the upper layer. The configured resources can be resources for the early transmission of data without Msg1 (Msg1-Less Early Data Transmission, Msg1-Less EDT). Among them, the resources can be used for the transmission of Msg3 of Msg1-Less EDT. Here, the data and / or signaling can be Msg3, for example.

[0317] Among them, the resources for Msg1-Less EDT can be competitive resources or non-competitive resources. For non-competitive resources, they can be preconfigured uplink resources (PUR) configured for the OCC resources of the terminal device. For competitive resources, no unique uplink resource / demodulation reference signal (DMRS) is configured for the terminal device. When using competitive resources, the terminal device can select an OCC / DMRS resource from the OCC / DMRS resource pool.
