Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular, to a method, apparatus, device, and storage medium for performing small data packet transmission and determining a random access message transmission mode. Background Art

[0002] Supporting small data packet transmission (SDT) in the inactive state means that data transmission can be completed without entering the connected state, so as to avoid wasting time-frequency resources, shorten the data transmission delay, and save the terminal power consumption.

[0124] The embodiments of the present disclosure will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0125] Here, the exemplary embodiments will be described in detail, and the examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the embodiments of the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0126] It should be noted that an embodiment of the present disclosure may include multiple steps; for the convenience of description, these steps are numbered; however, these numbers are not intended to limit the execution time slots and execution orders between the steps; these steps may be implemented in any order, and the embodiments of the present disclosure do not make any limitations in this regard.

[0127] When determining whether to enable small data packet transmission (SDT) based on the random access channel (RACH), it is necessary to make a judgment based on the signal strength received by the user equipment, such as SS-RSRP. That is, ensure that the SDT of small data packets is only transmitted under good coverage conditions to avoid wasting uplink transmission resources.

[0128] In addition, for the SDT of small data packets based on the RACH, whether to select the SDT of small data packets based on the 2-step RACH or the SDT of small data packets based on the 4-step RACH also needs to be determined based on the signal strength received by the user equipment.

[0129] In Release-17, due to the introduction of the Coverage Enhancement (CE) function, it is hoped that even user equipment with poor signal coverage at the cell edge can use the SDT of small data packets to reduce power consumption and resource overhead, and at the same time reduce data transmission latency.

[0130] Therefore, in order to enable user equipment with CE capabilities to perform the SDT of small data packets at the cell edge, the method of this application is proposed.

[0131] The embodiments of the present disclosure provide a method for performing the SDT of small data packets, which is executed by the user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 1 It is a flowchart of a method for performing the SDT of small data packets shown according to an exemplary embodiment, as Figure 1 shown, the method includes:

[0132] Step 101, measure the signal strength of the downlink signal;

[0133] Step 102, based on whether the user equipment has the Coverage Enhancement (CE) capability, obtain the signal strength threshold corresponding to the user equipment related to the SDT of small data packets;

[0134] Step 103, based on the signal strength and the signal strength threshold, perform the SDT of small data packets.

[0135] In one embodiment, the user equipment measures the signal strength of the downlink signal, and this signal strength is the Synchronization Signal-Reference Signal Receiving power (SS-RSRP).

[0136] In one embodiment, the user equipment obtains a corresponding threshold based on whether it has CE capability. In one embodiment, the user equipment obtains the threshold from the signaling received from the base station. In one embodiment, the user equipment obtains the threshold based on protocol regulations. Here, the threshold is used for the user to determine whether to perform small data packet transmission (SDT), and the specific manner adopted when performing SDT, such as SDT based on 2-step RACH and SDT based on 4-step RACH.

[0137] In one embodiment, the user equipment performs small data packet transmission (SDT) based on whether it has CE capability and the relationship between the signal strength and the threshold.

[0138] In this embodiment, when the user equipment determines to perform SDT, while considering the signal strength received by the user equipment, it also refers to its CE capability, so as to be applicable to the user equipment with CE capability to perform SDT.

[0139] The embodiments of the present disclosure provide a method for performing small data packet transmission (SDT), which is executed by the user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 2 is a flowchart of a method for performing small data packet transmission (SDT) shown according to an exemplary embodiment, as Figure 2 shown, the method includes:

[0140] Step 201, measure the signal strength of the downlink signal;

[0141] Step 202, in response to the user equipment having coverage enhancement (CE) capability, obtain a first threshold as the signal strength threshold of the user equipment;

[0142] Step 203, based on the signal strength and the signal strength threshold, perform small data packet transmission (SDT).

[0143] In one embodiment, the user equipment measures the signal strength of the downlink signal, and the signal strength is SS-RSRP. In one embodiment, the user equipment obtains the threshold based on the signaling received from the base station. In one embodiment, the user equipment obtains the threshold based on protocol regulations.

[0144] In one embodiment, when the user equipment has CE capability, obtain a first threshold, and based on the relationship between the signal strength and the first threshold, determine whether to perform small data packet transmission (SDT).

[0145] An embodiment of the present disclosure provides a method for performing Small Data Packet Transmission (SDT), which is executed by a user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 3 is a flowchart of a method for performing Small Data Packet Transmission (SDT) shown according to an exemplary embodiment, as Figure 3 shown, the method includes:

[0146] Step 301, measure the signal strength of the downlink signal;

[0147] Step 302, in response to the user equipment not having Coverage Enhancement (CE) capability, obtain a second threshold as the signal strength threshold of the user equipment;

[0148] Step 303, based on the signal strength and the signal strength threshold, perform Small Data Packet Transmission (SDT).

[0149] In one embodiment, the user equipment measures the signal strength of the downlink signal, and this signal strength is SS-RSRP. In one embodiment, the user equipment obtains the threshold based on the signaling received from the base station. In one embodiment, the user equipment obtains the threshold based on the protocol regulations.

[0150] In one embodiment, when the user equipment does not have CE capability, obtain a second threshold, and based on the relationship between the signal strength and the second threshold, determine whether to perform Small Data Packet Transmission (SDT).

[0151] An embodiment of the present disclosure provides a method for performing Small Data Packet Transmission (SDT), which is executed by a user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 4 is a flowchart of a method for performing Small Data Packet Transmission (SDT) shown according to an exemplary embodiment, as Figure 4 shown, the method includes:

[0152] Step 401, measure the signal strength of the downlink signal;

[0153] Step 402, in response to the user equipment having Coverage Enhancement (CE) capability, obtain a first threshold as the signal strength threshold of the user equipment;

[0154] Step 403, in response to the signal strength being greater than or equal to the first threshold, perform Small Data Packet Transmission (SDT) based on 4-step RACH.

[0155] In one embodiment, the user equipment measures the signal strength of the downlink signal, and this signal strength is SS-RSRP. In one embodiment, the user equipment obtains the threshold based on the signaling received from the base station. In one embodiment, the user equipment obtains the threshold based on the protocol regulations.

[0156] In one embodiment, when the user equipment has CE capability, a first threshold is obtained. When the signal strength is greater than or equal to the first threshold, small data packet transmission (SDT) based on 4-step RACH is performed. In one embodiment, when the signal strength is less than the first threshold, it indicates that the signal strength is poor, and thus small data packet transmission (SDT) is not performed.

[0157] In one embodiment, the first threshold is less than the second threshold described above. This is because for user equipment with CE capability, even when it is located at the cell edge, i.e., in an environment with poor signal coverage, small data packet transmission (SDT) can still be performed.

[0158] In this embodiment, for user equipment with CE capability, by comparing the signal strength of the received signal with a lower threshold to determine whether to perform small data packet transmission (SDT), the CE capability of the user equipment can be fully utilized, enabling it to perform small data packet transmission (SDT) even in areas with poor base station signal coverage, thereby reducing power consumption and resource overhead, and at the same time reducing data transmission latency.

[0159] Embodiments of the present disclosure provide a method for performing small data packet transmission (SDT). This method is executed by user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure. Figure 5 is a flowchart of a method for performing small data packet transmission (SDT) shown according to an exemplary embodiment, as Figure 5 shown, the method includes:

[0160] Step 501, measure the signal strength of the downlink signal;

[0161] Step 502, in response to the user equipment not having coverage enhancement (CE) capability, obtain the second threshold as the signal strength threshold of the user equipment;

[0162] Step 503, in response to the signal strength being greater than or equal to the second threshold, perform small data packet transmission (SDT) based on 4-step RACH.

[0163] In one embodiment, the user equipment measures the signal strength of the downlink signal, and this signal strength is SS-RSRP. In one embodiment, the user equipment obtains the threshold based on the signaling received from the base station. In one embodiment, the user equipment obtains the threshold based on protocol regulations.

[0164] In one embodiment, when the user equipment does not have CE capability, a second threshold is obtained. When the signal strength is greater than or equal to the second threshold, a small data packet transmission (SDT) based on 4-step RACH is performed. In one embodiment, when the signal strength is less than the second threshold, it indicates that the signal strength is poor, and thus the small data packet transmission SDT is not performed.

[0165] In one embodiment, the second threshold is greater than the first threshold mentioned above. This is because for user equipment without CE capability, when it is in an environment with poor signal coverage, since there is no CE capability to compensate for the signal strength of the poor downlink signal, the threshold for determining whether to perform small data packet transmission SDT needs to be set higher than the first threshold to ensure communication quality.

[0166] Embodiments of the present disclosure provide a method for performing small data packet transmission SDT, which is executed by user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure. Among them, the first threshold is less than the second threshold.

[0167] The first threshold is used to determine whether user equipment with CE capability performs small data packet transmission SDT, and the second threshold is used to determine whether user equipment without CE capability performs small data packet transmission SDT. The first threshold is less than the second threshold because for user equipment with CE capability, even when it is in an environment with poor signal coverage, it can perform small data packet transmission SDT, thereby reducing power consumption and resource overhead, and at the same time reducing data transmission delay.

[0168] Embodiments of the present disclosure provide a method for performing small data packet transmission SDT, which is executed by user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure.

[0169] Step 601, measure the signal strength of the downlink signal;

[0170] Step 602, in response to the user equipment having coverage enhancement (CE) capability, obtain the first threshold and the third threshold as the signal strength thresholds of the user equipment;

[0171] Step 603, in response to the signal strength being greater than or equal to the first threshold and less than the third threshold, activate the coverage enhancement (CE) capability of the user equipment and perform small data packet transmission SDT.

[0172] In one embodiment, the user equipment measures the signal strength of the downlink signal, and the signal strength is SS-RSRP. In one embodiment, the user equipment obtains a threshold related to small data packet transmission (SDT) based on the signaling received from the base station. In one embodiment, the user equipment obtains a threshold related to small data packet transmission (SDT) based on protocol regulations.

In one embodiment, when the user equipment does not have CE capability, if the signal strength is less than the seventh threshold, determine that the random access message transmission mode is the second transmission mode, for example, the random access message transmission mode based on the preamble resource in group A.

[0245] In one embodiment, the sixth threshold is less than the seventh threshold, and the sixth threshold is the threshold based on which the random access message transmission mode is determined for the user equipment with CE capability.

[0246] In this embodiment, the user equipment without CE capability can use the first transmission mode to transmit the random access message only when it is in an environment with good signal coverage.

[0247] The embodiments of the present disclosure provide a method for determining a random access transmission mode, which is executed by a user equipment; this method can be executed independently or in combination with any other embodiment of the present disclosure.
