Description

Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to an uplink transmission method, a terminal, a network-side device, a communication system, and related devices. Background Art

[0002] In uplink transmission (e.g., PRACH transmission), if an uplink transmission fails, the terminal must retransmit the uplink transmission to improve the success rate. Determining the initial number of uplink retransmissions and how to perform subsequent retransmissions is a key issue. Using uplink retransmissions by default can waste resources. Using a single uplink transmission and then retransmitting after certain conditions are met can result in excessive transmission latency.

[0003] Therefore, how to provide an uplink transmission method that takes into account both transmission resource utilization and transmission delay is a technical problem that needs to be solved urgently.

[0058] In some embodiments, the network-side device 20 may be a base station, a relay, or an access point. The base station may be, but is not limited to, a base station of 5G or later versions (e.g., 5G NR NB), or a base station in other communication systems (e.g., an eNB base station). It should be noted that the specific type of the network-side device is not limited in the embodiments of the present disclosure.

[0059] Those skilled in the art will know that Figure 1The number of terminals and network-side devices in the figure is merely illustrative, and any number of terminals, networks, and network-side devices may be provided according to actual needs. This disclosure does not limit this.

[0060] In the above system architecture, embodiments of the present disclosure provide an uplink transmission method that can be executed by any electronic device with computing and processing capabilities. In some embodiments, the uplink transmission method provided in the embodiments of the present disclosure can be executed by a terminal in the above system architecture; in other embodiments, the uplink transmission method provided in the embodiments of the present disclosure can be implemented through interaction between the terminal and network-side devices in the above system architecture.

[0061] Figure 2 A flow chart of an uplink transmission method according to an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the uplink transmission method provided in the embodiment of the present disclosure includes the following steps:

[0062] S202: Determine uplink transmission configuration information of the terminal, wherein the uplink transmission configuration information is at least used to determine an uplink transmission mode in which the terminal performs uplink transmission retransmission.

[0063] It should be noted that the uplink transmission configuration information in the above S202 can be configured by the network-side device, or can be determined by the terminal based on its communication environment or status information. It should be noted that in the embodiments of the present disclosure, the specific content of the uplink transmission configuration information is not limited, as long as it can be used to determine the uplink transmission retransmission mode executed by the terminal.

[0064] In some embodiments, the uplink transmission configuration information may include: uplink transmission mode indication information, where the uplink transmission mode indication information is used to indicate an uplink transmission mode for the terminal to perform uplink transmission retransmission.

[0065] In a specific implementation, when the uplink transmission mode includes multiple uplink transmission retransmission modes, the uplink transmission mode indication information can be used to indicate one or more uplink transmission retransmission modes that can be used by the terminal for uplink transmission. It should be noted that in the embodiments of the present disclosure, the form of the uplink transmission mode indication information is not limited, and those skilled in the art can configure the corresponding indication information according to actual needs.

[0066] S204: Execute uplink transmission of the terminal according to the uplink transmission configuration information.

[0067] It should be noted that, since the uplink transmission configuration information can be used to determine the uplink transmission mode in which the terminal performs uplink transmission retransmission, and then the uplink transmission of the terminal is performed according to the uplink transmission configuration information, it can be determined how to perform corresponding uplink transmission retransmission.

[0068] In some embodiments, the uplink transmission configuration information may include: a reference signal reception power threshold value set, the reference signal reception power threshold value set includes: one or more reference signal reception power threshold values, and different reference signal reception power threshold values ​​correspond to different maximum uplink transmission repetition times.

[0069] Since the reference signal received power can reflect the communication quality of the transmission channel between the terminal and the network side device, the larger the reference signal received power, the better the communication quality and the smaller the probability of uplink transmission failure. Therefore, a relatively large uplink transmission repetition number can be configured for a low reference signal received power threshold value, and a relatively small uplink transmission repetition number can be configured for a high reference signal received power threshold value, so as to reduce the transmission delay as much as possible while ensuring a high utilization rate of transmission resources.

[0070] From the above, it can be seen that the uplink transmission method provided in the embodiment of the present disclosure configures the uplink transmission mode of the terminal to perform uplink transmission retransmission in the uplink transmission configuration information of the terminal, so that the terminal performs the uplink transmission of the terminal according to the uplink transmission mode configured in the uplink transmission configuration information, and can make the uplink transmission retransmission of the terminal take into account the resource utilization and transmission delay of the uplink transmission resources, thereby improving the transmission performance of the uplink transmission.

[0144] 1-3) The uplink transmission configuration includes at least one of the following: a reference signal receiving power threshold set, uplink transmission mode indication information, a power threshold value, and a power deviation value.

[0145] The reference signal receiving power threshold set includes one or more power threshold values; and the uplink transmission mode indication information is used to instruct the terminal on a mode for performing uplink transmission retransmission.

[0146] In the embodiments of the present disclosure, uplink transmission modes include but are not limited to the following four:

[0147] First way:

[0148] 1) The terminal measures the downlink reference signal and compares it with the threshold value in the downlink reference signal reception power threshold set to determine the number of repetitions for uplink transmission.

[0149] 2) The terminal performs uplink transmission according to the determined number of repeated transmissions. If the transmission is unsuccessful and the number of uplink transmissions has not reached the maximum value, the terminal increases the transmission power when a preset condition is met, otherwise the transmission power is not increased and the uplink transmission is retransmitted.

[0150] 2-1) The preset condition may be that the signal transmission power of the terminal is less than the maximum transmission power of the terminal;

[0151] 2-2) The number of retransmissions of the uplink transmission is equal to the maximum number of retransmissions determined.

[0152] 2-3) The maximum number of repeated transmissions is one or other repeated transmission times configured on the network side.

[0153] 3) Repeat 2) until the uplink transmission is successful; or the number of uplink transmissions reaches the maximum number of uplink transmission repetitions of the terminal.

[0154] 3-1) If the uplink transmission times reach the maximum value and the transmission is still not successful, the uplink transmission fails.

[0155] Second way:

[0156] 1) The terminal measures the downlink reference signal and compares it with the threshold value in the downlink reference signal reception power threshold set to determine the number of repetitions for uplink transmission.

[0157] 2) The terminal performs uplink transmission according to the determined number of repeated transmissions. If the transmission is unsuccessful and the number of uplink transmissions has not reached the maximum value, the terminal increases the transmission power when a preset condition is met, otherwise the transmission power is not increased and the uplink transmission is retransmitted.

[0159] 2-2) The number of retransmissions of the uplink transmission is equal to the maximum number of retransmissions determined.

[0160] 2-3) The maximum number of repeated transmissions is one or other repeated transmission times configured on the network side.

[0162] 3-1) The preset power threshold value may be the maximum transmit power of the terminal, or the first power threshold value configured on the network side, or may be determined by a preset power deviation value configured on the network side.

[0163] 3-1-1) Determined by a preset power offset value configured on the network side. Specifically, the preset power threshold is determined by the user's maximum transmit power value and the preset power offset value configured on the network side. In one embodiment, the preset power offset value configured on the network side is ΔdB (Δ≥0), and the maximum transmit power value of the terminal is P. Then, the preset power threshold is equal to (P-Δ)dB.

[0164] 3-2) If the uplink transmission times reach the maximum value and the transmission is still not successful, the uplink transmission fails.

[0165] 4) The terminal increases the number of repeated transmissions of the uplink transmission and retransmits the uplink transmission until the uplink transmission is successful; or the number of uplink transmissions reaches a maximum value; or the number of uplink transmission retransmissions performed according to the number of repeated transmissions reaches a preset uplink transmission repetition threshold, and the number of uplink transmissions has not yet reached the maximum value at this time, and the network side has configured a number of repeated transmissions that is greater than the number of repeated transmissions currently performed by the terminal for uplink transmission, repeat step 4); or the network side has not configured a preset uplink transmission repetition threshold, and the number of uplink transmissions has not yet reached the maximum value at this time, repeat step 4), but the terminal keeps the number of repeated transmissions of the uplink transmission unchanged.

[0167] The third way:

[0168] 1) The terminal determines the transmit power of the uplink transmission. If the transmit power is less than a preset power threshold value (which may be consistent with the preset power threshold value in the second method described above, i.e., satisfies 3-1 and 3-1-1 in the second method), the terminal determines that the number of repeated transmissions of the uplink transmission is one; otherwise, the terminal measures the downlink reference signal and compares it with the threshold value in the downlink reference signal receive power threshold set to determine the number of repeated transmissions of the uplink transmission.

[0169] 2) The terminal performs uplink transmission according to the determined number of repeated transmissions. If the transmission is unsuccessful and the number of uplink transmissions has not reached the maximum value, the terminal increases the transmission power when a preset condition is met, otherwise the transmission power is not increased and the uplink transmission is retransmitted.

[0170] 2-1) The preset condition may be that the signal transmission power of the terminal is less than the maximum transmission power of the terminal;

[0171] 2-2) The number of retransmissions of the uplink transmission is equal to the maximum number of retransmissions determined.

[0173] 3-1) If the uplink transmission times reach the maximum value and the transmission is still not successful, the uplink transmission fails.

[0174] The fourth way:

[0175] 1) The terminal determines the transmit power of the uplink transmission. If the transmit power is less than a preset power threshold value (which may be consistent with the preset power threshold value in the second mode, i.e., satisfies 3-1 and 3-1-1 in the second mode), the terminal determines that the number of repeated transmissions of the uplink transmission is one; otherwise, the terminal measures the downlink reference signal and compares it with the threshold value in the downlink reference signal receive power threshold set to determine the number of repeated transmissions of the uplink transmission.

[0176] 2) The terminal performs uplink transmission according to the determined number of repeated transmissions. If the transmission is unsuccessful and the number of uplink transmissions has not reached the maximum value, the terminal increases the transmission power when a preset condition is met, otherwise the transmission power is not increased and the uplink transmission is retransmitted.

[0177] 2-1) The preset condition may be that the signal transmission power of the terminal is less than the maximum transmission power of the terminal;

[0178] 2-2) The number of retransmissions of the uplink transmission is equal to the maximum number of retransmissions determined.

[0179] 3) Repeat 2) until the uplink transmission is successful; or the number of uplink transmissions reaches the maximum value; or the terminal transmit power is greater than or equal to the preset power threshold value, and the number of uplink transmissions has not yet reached the maximum value, and the network side has configured a repetition number value that is greater than the number of repetitions for the uplink transmission determined by the terminal, then execute 4).

[0180] 3-1) If the uplink transmission times reach the maximum value and the transmission is still not successful, the uplink transmission fails.

[0181] 4) The terminal increases the number of repeated transmissions of the uplink transmission and retransmits the uplink transmission until the uplink transmission is successful; or the number of uplink transmissions reaches a maximum value; or the number of uplink transmission retransmissions performed according to the number of repeated transmissions reaches a preset uplink transmission repetition threshold, and the number of uplink transmissions has not yet reached the maximum value at this time, and the network side has configured a number of repeated transmissions that is greater than the number of repeated transmissions currently performed by the terminal for uplink transmission, repeat step 4); or the network side has not configured a preset uplink transmission repetition threshold, and the number of uplink transmissions has not yet reached the maximum value at this time, repeat step 4), but the terminal keeps the number of repeated transmissions of the uplink transmission unchanged.

[0182] 4-1) If the uplink transmission times reach the maximum value and the transmission is still not successful, the uplink transmission fails.

[0183] 2. The terminal performs uplink transmission according to the determined uplink transmission method.

[0184] At present, the 3GPP NR Realease-17 protocol does not support repeated transmission of PRACH (Physical Random Access Channel). According to the current protocol version, the terminal (UE) sends a Preamble (preamble code) at the PRACH transmission timing indicated by the base station. According to the time-frequency position of the PRACH transmission timing, the UE can calculate the corresponding RA-RNTI value. After that, the UE monitors the PDCCH within the random access response (RAR, Random Access Response) time window. If the UE successfully descrambles and detects DCI 1_0 with the RA-RNTI value, and can identify the RAPID number in the RAR information scheduled by the DCI, the UE considers that its PRACH transmission is successful, otherwise the UE needs to resend a new PRACH, which will bring additional transmission delay. Especially for high-frequency bands, PRACH is a potential coverage-limited channel. Therefore, it is necessary to consider how to enhance the coverage performance of PRACH. The above-mentioned uplink transmission method provided in the embodiment of the present disclosure is applied to PRACH transmission and can PRACH.
