[0167] When Early Data Transmission (EDT) is based on the random access process, a terminal device must go through at least four steps to send uplink data: sending message 1 (Msg1), receiving message 2 (Msg2), sending message 3 (Msg3), and receiving message 4 (Msg4).

[0168] Currently, the 3rd Generation Partnership Project (3GPP) is researching ways to increase uplink capacity through orthogonal cover codes (OCC). However, this uplink capacity increase only boosts the capacity of Msg1 and Msg3. Msg2 and Msg4 become bottlenecks that restrict system capacity. To address this issue, 3GPP is researching EDT methods that eliminate the need for Msg1 / Msg2 data transmission, meaning only Msg3 and Msg4 are used. A key focus of Msg3 research is how to directly send Msg3 without Msg1 and Msg2. For Msg4, the focus is on how to efficiently transmit Msg4 to increase its capacity.

[0169] Under what circumstances can a terminal device initiate Msg1-Less EDT? This is a key research topic in 3GPP.

[0194] 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.

[0195] The terminal device being set with a valid timing alignment value 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 (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.

[0196] In some embodiments, when the network device performs Msg1-Less EDT resource configuration through RRC dedicated signaling, the terminal device 101 can determine whether it has received the configuration information of the timer TAT configuration for the timing alignment of the early transmission of Msg1-Less EDT data without message 1 from the network device; if the configuration information is received, start the TAT timer; and determine that the terminal device is set with a valid timing alignment value.

[0197] When the terminal device receives the configuration information of the timer TAT configuration for the timing alignment of Msg1-Less EDT from the network device, it can store the current reference signal received power (RSRP) value of the serving cell to which the terminal device belongs.

[0198] 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 timing advance adjustment indicated by a timing advance command MAC control element (Timing Advance Command MAC control element) or a physical downlink control channel (Physical Downlink Control Channel, PDCCH) is received; when a timing advance adjustment indicated by a timing advance command MAC control element or a physical downlink control channel PDCCH is received, the timing alignment timer TAT is restarted; and it is determined that the terminal device is set with a valid timing alignment value.

[0199] In the case of restarting the timing alignment timer TAT, the terminal device may indicate the timing advance adjustment to the RRC layer through the media access control (MAC) layer of the terminal device. In the case of receiving the timing advance adjustment indicated by the MAC layer of the terminal device, the RRC layer of the terminal device 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.

[0200] In some embodiments, when the network device performs Msg1-Less EDT resource configuration through RRC dedicated signaling, the terminal device 101 can restart the timing alignment timer TAT after completing the random access process; and determine that the terminal device is set with a valid timing alignment value.

[0201] Among them, when the terminal device 101 is running the TAT timer, it can determine whether it has received the configuration information of the network device for releasing the TAT timer configuration for early transmission of data without message 1 Msg1-Less EDT; if the configuration information is received, the TAT timer is stopped.

[0202] In some embodiments, when the network device performs Msg1-Less EDT resource configuration through RRC dedicated signaling, the terminal device 101 may receive a temporary N signal before completing the random access process. TA In the case of N TA Set to the temporary N TA .

[0205] In some embodiments, the terms "MAC", "Media Access Control", "Media Access Control", etc. can be used interchangeably.

[0206] In some embodiments, when the configured resources are non-competitive resources for Msg1-Less EDT, the terminal device 101 can obtain the difference between the current reference signal received power RSRP value of the service cell to which the terminal device belongs and the stored service cell RSRP value; the difference is less than the specified RSRP change threshold value for early transmission of data without message 1 Msg1-Less EDT, and it is determined that the first condition is met.

[0207] Among them, the difference between the current RSRP value of the service cell to which the terminal device belongs and the stored service cell RSRP value can be a positive value or a negative value. When the difference is a positive value, the difference is an increase. That is to say, when the increase in the current RSRP value of the service cell to which the terminal device belongs relative to the stored service cell RSRP value is less than the specified RSRP change threshold value of Msg1-Less EDT, it is determined that the first condition is met. When the difference is a negative value, the difference is a decrease.

Among them, the detailed description of the next hop chaining value can be referred to the description in the protocol and will not be described in detail here.

[0212] In some embodiments, when resources are configured as non-competitive resources or competitive resources for Msg1-Less EDT, the terminal device 101 can transmit Msg1-Less CP EDT in advance for data without message 1 on the control plane, and determine whether the size of the media access control MAC packet data unit (PDU) containing EDT msg3 is less than or equal to the size of the maximum allowed transport block size (TBS); the size of the MAC PDU containing EDT msg3 is less than or equal to the size of the TBS, and it is determined that the first condition is met.
