[0052] It should be understood that in the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0053] In the embodiments of the present application, "predefined" can be implemented by pre-storing corresponding codes, tables, or other methods that can be used to indicate relevant information in a device (for example, a terminal device and a network device). The present application does not limit the specific implementation method. For example, predefined can refer to information defined in a protocol.

[0054] In the embodiments of the present application, "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, a NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0055] Next, we will introduce Early Data Transmission (EDT):

[0056] The LTE system introduces an EDT mechanism. During this process, the terminal device may always remain in an idle state, a suspended state, or an inactive state to complete the transmission of uplink and / or downlink small data packets. For example, a schematic diagram of the user plane transmission scheme is shown in Figure 1.

[0057] For example, the terminal device is a user equipment (UE) 101 and the network device is an evolved Node B (eNB) 102. After UE 101 transmits a random access preamble to eNB 102, eNB 102 feeds back a random access response to UE 101.

[0058] Step 1: UE 101 sends uplink data and a Radio Resource Control (RRC) connection resume request (RRCConnectionResumeRequest) to eNB 102. The RRC connection resume request includes at least one of the following: a resume identifier (resumeID), a resume cause (resumeCause), and a short resume medium access control integrity check (shortResume MAC-I).

[0059] Step 2: eNB 102 sends a UE Context Resume Request to the Mobility Management Entity (MME) 103 .

[0060] Step 3: The MME 103 and the Serving GateWay (S-GW) 104 perform a bearer modification process, including: the MME 103 sends a modify bearer request (Modify Bearer Request) to the S-GW 104, and the S-GW 104 sends a modify bearer response (Modify Bearer Response) to the MME 103.

[0061] Step 4: MME 103 sends a UE Context Resume Response to eNB 102 .

[0062] Step 5: eNB 102 sends uplink data to S-GW 104 .

[0063] Step 6: S-GW 104 sends downlink data to eNB 102 .

[0064] Step 7: An S1 Suspend procedure is performed between eNB102 and MME103, and a bearer modification procedure is performed between MME103 and serving gateway S-GW104, including: eNB102 sends an S1 Suspend Request to MME103, MME103 sends a Modify Bearer Request to S-GW104, S-GW104 sends a Modify Bearer Response to MME103, and MME103 sends an S1 Suspend Response to eNB102.

[0065] Step 8: eNB 102 sends downlink data and RRC Connection Release (RRCConnectionRelease) to UE 101. The RRC Connection Release includes at least one of the following: a release cause (releaseCause), a resume ID (resumeID), and a next hopping chain count (Next hopping Chain Count, NCC).

[0066] In the above data transmission process, the terminal device does not enter the connected state, and the transmission of the small data packet is completed by remaining in the idle state, the suspended state, or the inactive state.

[0067] In terms of configuration, the network device will configure a maximum transport block size (TB size) allowed by the current network on the System Information Block Type 2 (SIB2). The terminal device determines the amount of data to be transmitted. If it is less than the maximum TB size, the terminal device can use EDT; otherwise, the terminal device uses the normal connection establishment process to enter the connected state to transmit data.

[0068] Next, the contention-based random access process is introduced:

[0069] The terminal device supports a contention-based random access process. FIG2 shows a schematic diagram of a contention-based random access process provided by related art, which includes the following steps:

[0070] Step 210: The terminal device 410 sends a message 1 (msg1): a random access preamble code to the network device 420.

[0071] The terminal device 410 sends a selected random access preamble on the time-frequency resources of the selected physical random access channel (PRACH). The network device 420 can estimate the uplink delay and the grant size required for the terminal device 410 to transmit message 3 based on the random access preamble.

[0072] Step 220: The network device 420 sends a message 2 (msg2): Random Access Response (RAR) to the terminal device 410.

[0073] After sending message 1 (msg1), terminal device 410 opens a random access response window (RAR window) and monitors the physical downlink control channel (PDCCH) within the random access response window. The PDCCH is scrambled with a random access radio network temporary identifier (RA-RNTI).

[0074] After successfully monitoring the RA-RNTI-scrambled PDCCH, the terminal device 410 can obtain the Physical Downlink Shared Channel (PDSCH) scheduled by the PDCCH, where the PDSCH includes the RAR.

[0075] The RAR includes: a backoff indicator (BI), which is used to indicate the backoff time for retransmitting message 1; a random access preamble IDentifier (RAPID), which is used to indicate the random access preamble code; a timing advance group (TAG), which is used to adjust the uplink timing; an uplink grant, which is used to indicate the uplink resources for scheduling message 3; and a temporary cell-radio network temporary identity (Temporary C-RNTI), which is used to scramble the PDCCH (initial access) of message 4.

[0076] Step 230: The terminal device 410 sends a message 3 (msg3): Scheduled Transmission (ST) to the network device 420.

[0077] Message 3 is primarily used to notify network device 420 of the event that triggered the random access procedure. For example, if the event is an initial random access procedure, Message 3 carries the terminal device identification (ID) and establishment cause; if the event is a radio resource control (RRC) reestablishment, Message 3 carries the connected terminal device ID and establishment cause. Furthermore, the terminal device ID or connected terminal device ID carried in Message 3 enables contention resolution in step 240.

[0078] Step 240: The network device 420 sends message 4 (msg4): contention resolution message to the terminal device 410.

[0079] Message 4 has two functions. First, message 4 can be used to resolve contention conflicts. Second, message 4 is a message for the network device 420 to transmit RRC configuration to the terminal device 410.

[0080] Resolving contention conflicts means that the terminal device 410 receives the PDSCH of message 4 and performs scheduling by matching the Common Control Channel Signal Distribution Unit (CCCH SDU) in the PDSCH. There are two scheduling methods:

[0081] 1. If the terminal device 410 carries the temporary C-RNTI in message 3, message 4 is scheduled using the PDCCH scrambled with the temporary C-RNTI.

[0082] 2. The terminal device 410 does not carry the temporary C-RNTI in message 3. For example, if the random access process is initial access, message 4 uses the PDCCH scrambled by the temporary C-RNTI for scheduling.

[0083] Next, the Coverage Enhancement Level (CE level) is introduced:

[0084] In a related technology, such as the Narrowband Internet of Things (NB-IoT), there are three CE levels: Level 0, Level 1, and Level 2, corresponding to resistance to signal attenuation of 144dB, 154dB, and 164dB, respectively. The number of message retransmissions between network devices and end devices is determined based on the CE level of the end device.

[0085] Figure 3 shows a schematic diagram of coverage enhancement levels provided by related technologies. With network device 420 as the center, a first signal coverage range within a distance R0 from network device 420 corresponds to CE Level 0 (CE 0), a second signal coverage range between R0 and R1 from network device 420 corresponds to CE Level 1 (CE 1), and a third signal coverage range between R1 and R2 from network device 420 corresponds to CE Level 2 (CE 2). When the distance from network device 420 is greater than R2, the signal quality is too poor and does not correspond to the CE level.

[0086] The terminal device determines the CE level according to the measurement result of the Reference Signal Receiving Power (RSRP) and the RSRP threshold value configured by the network device. For example, the network device configures 3 RSRP threshold values, RSRP1, RSRP2, and RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the CE level corresponding to the terminal device is level 0; when RSRP2 ≤ RSRP < RSRP1, the CE level corresponding to the terminal device is level 1; when RSRP3 ≤ RSRP < RSRP2, the CE level corresponding to the terminal device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0087] Exemplarily, when the terminal device 410 is in the position shown in Figure 3, by comparing the RSRP measurement result and the RSRP threshold value, it is determined that the CE level is level 2, and it can withstand a signal attenuation of 164 decibels.

[0088] Next, the Preconfigured Uplink Resources (PUR) will be introduced:

[0089] To further save energy, the LTE system supports PUR transmission. PUR is dedicated uplink resource, which is configured by the network device to the terminal device when the connection is released. PUR does not need to use the random access process, and PUR is UE-specific resource, and there is no competition and interference between terminal devices using PUR resources.

[0090] Figure 4 shows a schematic diagram of a mobile communication system provided by an exemplary embodiment of the present application. The mobile communication system includes a terminal device 410 and a network device 420, and may or may not include a terminal device 430, which is not limited in the present application.

[0091] The terminal device 410 in this application is also called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, and user device.

[0092] The network device 420 in the present application provides wireless communication functions, and the network device 420 includes but is not limited to: Evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home Base Station (e.g., Home Evolved Node B, or Home Node B, HNB), Base Band Unit (BBU), Access Point (AP) in Wireless Fidelity (Wi-Fi) system, Wireless Relay Node, Wireless Backhaul Node, Transmission Point (TP) or Transmission and Reception Point (TRP), etc., and can also be the Next Generation Node B (NGNB) in the 5th Generation (5G) mobile communication system. The term "gNB" refers to a base station (B, gNB) or a transmission point (TRP or TP), or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or a transmission point, such as a baseband unit (BBU) or a distributed unit (DU), or a base station in a Beyond Fifth Generation (B5G) or a 6th Generation (6G) mobile communication system, or a core network (CN), fronthaul, backhaul, radio access network (RAN), network slicing, or a serving cell, primary cell (PCell), primary secondary cell (PSCell), special cell (SpCell), secondary cell (SCell), or neighboring cell of a terminal device.

[0093] In some embodiments, the network device 420 and the terminal device 410 communicate with each other via some air interface technology, such as a Uu interface.

[0094] Exemplarily, there are two communication scenarios between network device 420 and terminal device 410: uplink communication scenario and downlink communication scenario. Uplink communication, or uplink transmission, refers to sending signals or data to network device 420; downlink communication, or downlink transmission, refers to sending signals or data to terminal device 410.

[0095] In some embodiments, the terminal device 410 and the terminal device 430 communicate with each other via some air interface technology, such as a PC5 interface.

[0096] For example, there are two communication scenarios between terminal device 410 and terminal device 430: a first sideline communication scenario and a second sideline communication scenario. The first sideline communication refers to terminal device 410 sending a signal to terminal device 430, while the second sideline communication refers to terminal device 430 sending a signal to terminal device 410.

[0097] In some embodiments, terminal device 410 and terminal device 430 are both within the network coverage and located in the same cell, or terminal device 410 and terminal device 430 are both within the network coverage but located in different cells, or terminal device 410 is within the network coverage but terminal device 430 is outside the network coverage.

[0098] In some embodiments of the present application, "NR" may also be referred to as a 5G NR system or a 5G system. A 5G mobile communication system may include a non-standalone (NSA) network and / or a standalone (SA) network.

[0099] The technical solutions provided in the embodiments of the present application can also be applied to machine type communication (MTC), long term evolution technology for machine-to-machine communication (LTE-M), device-to-device (D2D) network, machine-to-machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network can include, for example, the Internet of Vehicles. Among them, the communication mode in the Internet of Vehicles system is collectively referred to as vehicle to other devices (Vehicle to X, V2X, X can represent anything), for example, the V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian communication (V2P) or vehicle to network (V2N) communication, etc.

[0100] The mobile communication system provided in the embodiment of the present application can be applied to but not limited to at least one of the following communication scenarios: an uplink communication scenario, a downlink communication scenario, and a sidelink communication scenario.

[0101] The contention-based random access method includes message 1 (msg1), message 2 (msg2), message 3 (msg3), and message 4 (msg4). In related technologies, a terminal device must be in a connected state to transmit uplink information. However, when the terminal device is in an idle or inactive state, how to transmit uplink information with high reliability remains an urgent problem.

[0102] To solve the above problems, an embodiment of the present application provides a method for switching transmission modes. FIG5 shows a flow chart of a method for switching transmission modes provided by an exemplary embodiment of the present application. The method is executed by a terminal device in an idle or inactive state, and the method includes:

[0103] Step 510: When the first condition is met, the transmission mode of the first information is converted from the first uplink transmission mode to the second uplink transmission mode.

[0104] The first uplink transmission mode or the second uplink transmission mode includes: using pre-configured PUSCH resources for transmission.

[0105] In some embodiments, transmission can be understood as at least one of direct transmission, direct transmission of message 3, transmission without scheduling, transmission without message 1, transmission without RAR, transmission without sending message 1, and transmission without receiving RAR. Message 1 refers to message 1 during a random access process, and RAR refers to message 2 during a random access process.

[0106] In some embodiments, using preconfigured PUSCH resource transmission can be understood as: using at least one of contention-based PUSCH resource transmission, using message 3 direct transmission resource transmission, using PUSCH resource transmission without message 1, and using PUSCH resource transmission without RAR.

[0107] In some embodiments, the first condition can be understood as at least one of a conversion condition, a switching condition, a transformation condition, and a fallback condition.

[0108] In some embodiments, the reliability of the second uplink transmission mode is higher than the reliability of the first uplink transmission mode.

[0109] In some embodiments, under the condition of the same data volume, the uplink resources used by the second uplink transmission mode are better than or more than the uplink resources used by the first uplink transmission mode.

[0110] In some embodiments, the first uplink transmission mode and the second uplink transmission mode are both direct transmission modes when the terminal device is in an idle state or an inactive state, without requiring Message 1 and / or RAR.

[0111] In some embodiments, the PUSCH resource is a contention-based PUSCH resource. For example, in a contention-based random access mechanism, the PUSCH resource is a resource used to transmit message 3 (msg3); for another example, in a message 3 direct transmission mechanism, the PUSCH resource is a resource used to directly transmit message 3.

[0112] In some embodiments, the first information includes first signaling; or, the first information includes first signaling and first data.

[0113] In some embodiments, the first signaling includes at least one of the following: an RRC connection establishment request (RRCSetupRequest), an RRC connection resumption request (RRCConnectionResumeRequest), and an early data request (EarlyDataRequest).

[0114] Among them, the RRC connection establishment request is used to request the establishment of an RRC connection. The terminal device sends the RRC connection establishment request to the network device to initiate the connection process; the RRC connection recovery request is used to request the restoration of the RRC connection. When the terminal device is in a non-connected state and hopes to restore the connection, the request is sent to the network device; the early data request is used to request partial data transmission before the RRC connection is established, so as to improve the connection speed and optimize the transmission performance.

[0115] In some embodiments, the first uplink transmission mode and the second uplink transmission mode include at least one of the following three situations:

[0116] The first scenario: the first uplink transmission mode includes: using a pre-configured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a pre-configured second type of PUSCH resource for transmission.

[0117] Second scenario: the first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0118] The third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0119] In some embodiments, the PUSCH resources (including first type PUSCH resources and second type PUSCH resources) are resources configured by a network device.

[0120] For the first scenario: the first uplink transmission mode includes: using a preconfigured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a preconfigured second type of PUSCH resource for transmission.

[0121] In some embodiments, the first condition includes: the number of times the terminal device transmits the first information reaches a first transmission number, and the first transmission number is the maximum number of transmission attempts corresponding to the first type of PUSCH resource.

[0122] When the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission.

[0123] Since there is contention between terminal devices when using a PUSCH resource transmission mechanism (such as the message 3 direct transmission mechanism), allowing multiple retransmissions can increase the probability of resolving contention conflicts.

[0124] In some embodiments, the first transmission number is configured by the network device.

[0125] Configuring the first transmission number through a network device can support a variety of configuration methods, thereby performing configuration according to actual needs.

[0126] In some embodiments, the maximum number of retransmission attempts includes the initial transmission. For example, if the initial transmission fails and the maximum number of retransmission attempts is 4, then a maximum of 3 retransmissions are allowed. In the embodiments of the present application, the maximum number of retransmission attempts includes the initial transmission as an example.

[0127] In some embodiments, the maximum number of transmission attempts does not include the initial transmission. For example, if the initial transmission fails and the maximum number of transmission attempts is 4, then a maximum of 4 retransmissions are allowed. In this case, the maximum number of transmission attempts can be understood as the maximum number of retransmission attempts.

[0128] In some embodiments, the first repetition number is smaller than the second repetition number, the first repetition number is the repetition number corresponding to the first type of PUSCH resources, and the second repetition number is the repetition number corresponding to the second type of PUSCH resources.

[0129] For example, a transmission or retransmission includes multiple repetitions of the same information. The number of repetitions refers to the number of times the same information is repeated in a transmission or retransmission. For example, if the string to be transmitted is 0110 and the number of repetitions is 3, the transmitted string is 011001100110.

[0130] Since the channel quality of the terminal device may continue to deteriorate due to various reasons, such as the deterioration of the channel quality caused by satellite in the non-terrestrial network (NTN) scenario, using PUSCH resources corresponding to more repetitions for transmission can improve the success rate of transmission.

[0131] In some embodiments, the method further includes: retransmitting the first information if transmission of the first information fails using the preconfigured first type PUSCH resources.

[0132] Possible situations in which the transmission of the first information fails include at least one of the following: the first timer times out; the network device indicates that the transmission of the first information fails or is terminated; the transmission of the first information is interfered with by other devices; multiple devices attempt to transmit the first information simultaneously.

[0133] In some embodiments, the first timer is a timer started when the terminal device uses the first type of PUSCH resource to transmit the first information, and the first timer is used to limit the time for transmitting the first information.

[0134] In some embodiments, when the first timer expires, the first information is retransmitted.

[0135] Exemplarily, the first timer limits the time for transmitting the first information to 100 milliseconds, with the moment when the terminal device starts transmitting the first information using the first type of PUSCH resource as the starting moment. When the first timer exceeds 100 milliseconds, the first information is retransmitted.

[0136] By using a timer to determine whether the transmission of the first information fails, the implementation is simple and the control is convenient.

[0137] In some embodiments, the method further comprises: if the i-th retransmission fails, performing an i+1-th retransmission until the number of transmissions of the first information reaches the first number of transmissions;

[0138] The first number of transmission attempts is the maximum number of transmission attempts corresponding to the first type of PUSCH resources, and i is a positive integer.

[0139] By retransmitting the first information when the transmission of the first information fails, and continuing to retransmit the first information when the retransmission fails until the number of transmissions of the first information reaches the first number of transmissions, the transmission success rate of the first information is improved.

[0140] In some embodiments, a first type of PUSCH resource is associated with a first CE level, and a second type of PUSCH resource is associated with a second CE level.

[0141] There are three CE levels: Level 0, Level 1, and Level 2, corresponding to resistance to signal attenuation of 144dB, 154dB, and 164dB, respectively. The number of message repetitions between network devices and end devices is determined by the CE level of the end device.

[0142] In some embodiments, the first CE level is a CE level determined by the terminal device based on a reference signal receiving power (RSRP) measurement result and an RSRP threshold value configured by the network device; or, the first CE level is a CE level specified by the network device when the RRC connection is released.

[0143] In some embodiments, the terminal device obtains the signal quality of a cell-specific reference signal (CRS) by measuring the CRS, and the measurement result of the CRS is represented by RSRP.

[0144] Exemplarily, the network device configures 3 RSRP threshold values, RSRP1, RSRP2, and RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the corresponding CE level of the terminal device is level 0; when RSRP2 ≤ RSRP < RSRP1, the corresponding CE level of the terminal device is level 1; when RSRP3 ≤ RSRP < RSRP2, the corresponding CE level of the terminal device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0145] When the first CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the network device, the first CE level is more in line with the scenario where the terminal device is located and has higher accuracy; when the first CE level is the CE level specified by the network device during RRC connection release, the CE level can be specified according to actual needs without performing RSRP measurement.

[0146] In some embodiments, the second CE level is the CE level obtained by adding a preset level to the first CE level; or, the second CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the network device.

[0147] In some embodiments, the second CE level is the CE level obtained by adding one level to the first CE level. For example, if the first CE level is level 1, the second CE level is level 2; or, the second CE level is the CE level obtained by adding two levels to the first CE level, with an upper limit of level 2. For example, if the first CE level is level 0, the second CE level is level 2, or if the first CE level is level 1, the second CE level is level 2. [[ID=...]]

[0148] In some embodiments, the second CE level is the CE level determined by the terminal device according to the current RSRP measurement result and the RSRP threshold value configured by the network device. The determination method is as described above and will not be elaborated here.

[0149] When the second CE level is the CE level obtained by adding a preset level to the first CE level, RSRP measurement is not required and the implementation is simple; when the second CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the network device, the second CE level is more in line with the scenario where the terminal device is located and has higher accuracy.

[0150] Figure 6 shows a schematic diagram of a method for converting a transmission mode provided by an exemplary embodiment of the present application. The network device pre-configures multiple PUSCH resources, wherein the number of repetitions of the PUSCH resources corresponding to CE level 0 (CE 0) is 2, that is, after transmitting the first message, the first message is repeatedly transmitted once; the number of repetitions of the PUSCH resources corresponding to CE level 1 (CE 1) is 3, that is, after transmitting the first message, the first message is repeatedly transmitted twice; the number of repetitions of the PUSCH resources corresponding to CE level 2 (CE 2) is 4, that is, after transmitting the first message, the first message is repeatedly transmitted three times. The periods of the PUSCH resources corresponding to different CE levels are the same or different. In the embodiment of the present application, the same period is used as an example for illustration.

[0151] Taking the maximum number of transmission attempts corresponding to the pre-configured first type of PUSCH resources including the initial transmission, the maximum number of transmission attempts is n+1 times, and the number of repetitions (the first number of repetitions) is 3, that is, after transmitting the first message, the first message is repeated twice. For example, n is a positive integer.

[0152] If the initial transmission using the preconfigured first type of PUSCH resources fails, for example, if the first timer times out, a first retransmission is performed. If the first retransmission fails, a second retransmission is performed. After n retransmissions, the transmission switches to using the preconfigured second type of PUSCH resources. The number of repetitions corresponding to the second type of PUSCH resources (the second number of repetitions) is 4, which is greater than the first number of repetitions.

[0153] For the second scenario: the first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0154] In some embodiments, the first condition includes: occurrence of a first event.

[0155] Figure 7 is a schematic diagram of a transmission mode conversion method provided by an exemplary embodiment of the present application. The network device is preconfigured with multiple PUSCH resources and PURs. White squares indicate PUSCH resources, and squares filled with diagonal lines indicate PURs. The PUSCH resources corresponding to different CE levels may have the same or different periods. In this embodiment, the same period is used as an example for illustration.

[0156] For example, taking the PUSCH resource corresponding to CE level 2 (CE 2) as an example, the number of repetitions is 4, that is, after transmitting the first message, the first message is repeatedly transmitted three times. When the first event occurs, the transmission mode of the first information is switched from using PUR transmission to using pre-configured PUSCH resources.

[0157] In some embodiments, the first event includes at least one of the following: a second timer timeout; a network device indicating a PUR transmission failure; a network device indicating a PUR transmission termination; wherein the second timer is used to limit the PUR transmission time.

[0158] In some embodiments, the network device indicates PUR transmission failure or termination by configuring indication signaling, and the indication signaling includes at least one of a physical downlink control channel (PDCCH), a medium access control control element (MAC CE), and an RRC signaling.

[0159] When the first event occurs, the transmission mode is changed. For example, when the first event is the timeout of the second timer, the implementation is simple and easy to control. When the first event is the network device indicating that the PUR transmission has failed or terminated, the conversion is performed according to the indication signaling. The operation is accurate and there is no need to introduce other mechanisms.

[0160] In some embodiments, the preconfigured PUSCH resources are associated with the fourth CE level.

[0161] In some embodiments, the fourth CE level is a CE level determined by the terminal device based on the RSRP measurement result and the RSRP threshold value configured by the network device. The specific implementation details refer to the embodiment of the first case and are not repeated here.

[0162] In some embodiments, the second timer is a timer started by the terminal device when using PUR transmission, and the second timer is used to limit the time of PUR transmission. The operation principle of the second timer is the same as that of the first timer, which will not be repeated here.

[0163] PUR transmission failure may be due to deteriorating channel quality, and the PUR configured by the network device cannot adapt to the deteriorating channel quality. In this case, it falls back to using PUSCH resources for transmission (for example, direct transmission of message 3). The PUSCH resource transmission mechanism can select PUSCH resources that adapt to the channel quality, improving the transmission success rate.

[0164] For the third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0165] In some embodiments, the first condition includes: occurrence of a second event.

[0166] Figure 8 is a schematic diagram of a transmission mode conversion method provided by an exemplary embodiment of the present application. The network device is preconfigured with multiple PUSCH resources and EDT resources. White squares are used to indicate PUSCH resources, and squares filled with crosses are used to indicate EDT resources. The periods of PUSCH resources corresponding to different CE levels may be the same or different. In the embodiment of the present application, the same period is used as an example for illustration.

[0167] For example, taking the PUSCH resource corresponding to CE level 1 (CE 1) as an example, the number of repetitions is 3, that is, after transmitting the first message, the first message is repeatedly transmitted twice. In the event of the second event, the transmission mode of the first message is switched from using the preconfigured PUSCH resource to using the EDT resource.

[0168] In some embodiments, the second event includes at least one of the following: a third timer times out; the network device indicates that the transmission of the first information fails; the network device indicates that the transmission of the first information is terminated; the number of times the first information is transmitted reaches a second transmission number;

[0169] The third timer is used to limit the time for transmitting the first information, and the second number of transmission attempts is the maximum number of transmission attempts corresponding to the PUSCH resource.

[0170] In the event of a second event, the transmission mode is changed. For example, when the second event is the timeout of the third timer, the implementation is simple and easy to control. When the second event is the network device indicating that the transmission of the first information has failed or terminated, the conversion is performed according to the indication signaling, the operation is accurate, and there is no need to introduce other mechanisms. When the second event is that the number of times the first information is transmitted reaches the second number of transmissions, it is easy to monitor, and when the number of times the first information is transmitted has reached the maximum number of transmission attempts, the first information is likely to fail to be transmitted, which meets the timing for changing the transmission mode.

[0171] Taking the second event that the number of times the first information is transmitted reaches the second transmission number as an example, as shown in Figure 9, the maximum number of transmission attempts corresponding to the pre-configured PUSCH resources includes the initial transmission, and the maximum number of transmission attempts is n+1 times, where n is a positive integer.

[0172] If the first transmission using the pre-configured PUSCH resources fails, the first retransmission is performed. After the first retransmission fails, the second retransmission is performed. After n retransmissions, the transmission switches to using EDT resources.

[0173] In some embodiments, the second transmission number is configured by the network device.

[0174] Configuring the second transmission number through a network device can support a variety of configuration methods, thereby performing configuration according to actual needs.

[0175] In some embodiments, the third timer is a timer started by the terminal device when transmitting the first information using pre-configured PUSCH resources. The third timer is used to limit the time for transmitting the first information. The principle of using the third timer is the same as that of the first timer, which will not be elaborated here.

[0176] In some embodiments, the EDT resource is related to the third CE level.

[0177] In some embodiments, the third CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the network device; or, the third CE level is the CE level associated with the last transmission of the first information in the case of transmission failure of the first information; or, the third CE level is the CE level obtained by increasing a preset level on the CE level associated with the last transmission of the first information in the case of transmission failure of the first information.

[0178] In some embodiments, the terminal device obtains the signal quality of the CRS by measuring the CRS, and the measurement result of the CRS is represented by RSRP.

[0179] Exemplarily, the network device configures 3 RSRP threshold values, RSRP1, RSRP2, RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the corresponding CE level of the terminal device is level 0; when RSRP2 ≤ RSRP < RSRP1, the corresponding CE level of the terminal device is level 1; when RSRP3 ≤ RSRP < RSRP2, the corresponding CE level of the terminal device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0180] In some embodiments, in the case of transmission failure of the first information, the CE level associated with the last transmission of the first information is level m, and the third CE level is level m, where m takes the value of 0 or 1 or 2. For example, if the CE level associated with the last transmission of the first information is level 1, then the third CE level is level 1.

[0181] In some embodiments, in the case of transmission failure of the first information, the third CE level is the CE level obtained by increasing one level on the CE level associated with the last transmission of the first information. For example, if the CE level associated with the last transmission of the first information is level 1, the third CE level is level 2; or, the third CE level is the CE level obtained by increasing two levels on the CE level associated with the last transmission of the first information, with the upper limit being level 2. For example, if the CE level associated with the last transmission of the first information is level 0, the third CE level is level 2, or if the CE level associated with the last transmission of the first information is level 1, the third CE level is level 2.

[0182] When the third CE level is the CE level determined by the terminal device based on the RSRP measurement results and the RSRP threshold value configured by the network device, the third CE level is more in line with the scenario in which the terminal device is located and has higher accuracy; when the third CE level is the CE level associated with the last transmission of the first information, RSRP measurement is not required and the implementation is simple; when the third CE level is a CE level with a preset level added to the CE level associated with the last transmission of the first information, it is more reasonable and can find the appropriate CE level faster.

[0183] The failure of transmission using PUSCH resources may be due to incorrect PUSCH resource configuration. Since transmission using PUSCH resources (such as direct transmission of message 3) is not suitable for dynamic scheduling, PUSCH resources cannot be changed after the configuration error. After switching to transmission using EDT resources, dynamic scheduling during the random access process can be used to improve the transmission situation and increase the transmission success rate.

[0184] In some embodiments, the transmission mode conversion methods of the first situation and the second situation can be used in combination, that is, when a first event occurs, the transmission mode of the first information is converted from using PUR transmission to using preconfigured first type of PUSCH resource transmission, and then when the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using preconfigured first type of PUSCH resource transmission to using preconfigured second type of PUSCH resource transmission.

[0185] In some embodiments, the transmission mode conversion methods of the first situation and the third situation can be used in combination, that is, when the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission; in the event of a second event, the transmission mode of the first information is converted from using the preconfigured second type of PUSCH resource transmission to using EDT resources transmission.

[0186] In some embodiments, the transmission mode conversion methods of the second and third situations can be used in combination, that is, when the first event occurs, the transmission mode of the first information is converted from using PUR transmission to using pre-configured PUSCH resources for transmission, and then when the second event occurs, the transmission mode of the first information is converted from using pre-configured PUSCH resources for transmission to using EDT resources for transmission.

[0187] The embodiments of the present application do not limit the combined use of the above-mentioned transmission mode conversion methods. For specific implementation details, please refer to the above-mentioned embodiments and will not be repeated here.

[0188] To summarize, the method provided in this embodiment converts the transmission mode of the first information from the first uplink transmission mode to the second uplink transmission mode when the first condition is met; wherein, the first uplink transmission mode or the second uplink transmission mode includes: using pre-configured PUSCH resources for transmission, so that when the first information fails to be transmitted, it is converted to a different uplink transmission mode, thereby improving the transmission possibility in the idle state or inactive state, and increasing the success rate of uplink transmission in the idle state or inactive state.

[0189] FIG10 shows a flowchart of an information receiving method provided by an exemplary embodiment of the present application. The method is executed by a network device and includes:

[0190] Step 1010: Receive first information transmitted using a first uplink transmission method.

[0191] In some embodiments, transmission can be understood as at least one of direct transmission, direct transmission of message 3, transmission without scheduling, transmission without message 1, transmission without RAR, transmission without sending message 1, and transmission without receiving RAR. Message 1 refers to message 1 during a random access process, and RAR refers to message 2 during a random access process.

[0192] In some embodiments, the first information includes first signaling; or, the first information includes first signaling and first data.

[0193] In some embodiments, the first signaling includes at least one of the following: an RRC connection establishment request (RRCSetupRequest), an RRC connection resumption request (RRCConnectionResumeRequest), and an early data request (EarlyDataRequest).

[0194] Among them, the RRC connection establishment request is used to request the establishment of an RRC connection. The terminal device sends the RRC connection establishment request to the network device to initiate the connection process; the RRC connection recovery request is used to request the restoration of the RRC connection. When the terminal device is in a non-connected state and hopes to restore the connection, the request is sent to the network device; the early data request is used to request partial data transmission before the RRC connection is established, so as to improve the connection speed and optimize the transmission performance.

[0195] Step 1020: Receive first information transmitted using the second uplink transmission method.

[0196] The second uplink transmission mode is an uplink transmission mode determined by a terminal device in an idle state or an inactive state when the first condition is met. The first uplink transmission mode or the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0197] In some embodiments, using preconfigured PUSCH resource transmission can be understood as: using at least one of contention-based PUSCH resource transmission, using message 3 direct transmission resource transmission, using PUSCH resource transmission without message 1, and using PUSCH resource transmission without RAR.

[0198] In some embodiments, the first condition can be understood as at least one of a conversion condition, a switching condition, a transformation condition, and a fallback condition.

[0199] In some embodiments, the reliability of the second uplink transmission mode is higher than the reliability of the first uplink transmission mode.

[0200] In some embodiments, under the condition of the same data volume, the uplink resources used by the second uplink transmission mode are better than or more than the uplink resources used by the first uplink transmission mode.

[0201] In some embodiments, the first uplink transmission mode and the second uplink transmission mode are both direct transmission modes when the terminal device is in an idle state or an inactive state, without requiring Message 1 and / or RAR.

[0202] In some embodiments, the PUSCH resource is a contention-based PUSCH resource. For example, in a contention-based random access mechanism, the PUSCH resource is a resource used to transmit message 3 (msg3); for another example, in a message 3 direct transmission mechanism, the PUSCH resource is a resource used to directly transmit message 3.

[0203] In some embodiments, the first uplink transmission mode and the second uplink transmission mode include at least one of the following three situations:

[0204] The first scenario: the first uplink transmission mode includes: using a pre-configured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a pre-configured second type of PUSCH resource for transmission.

[0205] Second scenario: the first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0206] The third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0207] In some embodiments, the PUSCH resources (including first type PUSCH resources and second type PUSCH resources) are resources configured by a network device.

[0208] For the first scenario: the first uplink transmission mode includes: using a preconfigured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a preconfigured second type of PUSCH resource for transmission.

[0209] In some embodiments, the first condition includes: the number of times the terminal device transmits the first information reaches a first transmission number, and the first transmission number is the maximum number of transmission attempts corresponding to the first type of PUSCH resource.

[0210] When the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission.

[0211] Since there is contention between terminal devices when using a PUSCH resource transmission mechanism (such as the message 3 direct transmission mechanism), allowing multiple retransmissions can increase the probability of resolving contention conflicts.

[0212] In some embodiments, the maximum number of retransmission attempts includes the initial transmission. For example, if the initial transmission fails and the maximum number of retransmission attempts is 4, then a maximum of 3 retransmissions are allowed. In the embodiments of the present application, the maximum number of retransmission attempts includes the initial transmission as an example.

[0213] In some embodiments, the maximum number of transmission attempts does not include the initial transmission. For example, if the initial transmission fails and the maximum number of transmission attempts is 4, then a maximum of 4 retransmissions are allowed. In this case, the maximum number of transmission attempts can be understood as the maximum number of retransmission attempts.

[0214] In some embodiments, the first repetition number is smaller than the second repetition number, the first repetition number is the repetition number corresponding to the first type of PUSCH resources, and the second repetition number is the repetition number corresponding to the second type of PUSCH resources.

[0215] For example, a transmission or retransmission includes multiple repetitions of the same information. The number of repetitions refers to the number of times the same information is repeated in a transmission or retransmission. For example, if the string to be transmitted is 0110 and the number of repetitions is 3, the transmitted string is 011001100110.

[0216] Since the channel quality of the terminal device may continuously deteriorate due to various reasons, for example, in the Non Terrestrial Network (NTN) scenario, the channel quality deteriorates due to the satellite provided, using PUSCH resources with more corresponding repetition times for transmission can improve the transmission success rate.

[0217] In some embodiments, the method further includes: configuring a first transmission number, where the first transmission number is the maximum number of transmission attempts corresponding to the first type of PUSCH resource.

[0218] Configuring the first transmission number by the network device can support diverse configuration methods, so as to configure according to actual requirements.

[0219] In some embodiments, the first type of PUSCH resource is related to the first CE level, and the second type of PUSCH resource is related to the second CE level.

[0220] There are three CE levels in total: level 0, level 1, and level 2, corresponding to signal attenuations that can withstand 144 dB, 154 dB, and 164 dB respectively. The network device and the terminal device will select the corresponding information repetition times according to the CE level corresponding to the terminal device.

[0221] In some embodiments, the first CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the network device; or, the first CE level is the CE level specified by the network device when the RRC connection is released.

[0222] In some embodiments, the terminal device obtains the signal quality of the CRS by measuring the CRS, and the measurement result of the CRS is represented by the RSRP.

[0223] Exemplarily, the network device configures 3 RSRP threshold values, RSRP1, RSRP2, RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the CE level corresponding to the terminal device is level 0; when RSRP2 ≤ RSRP < RSRP1, the CE level corresponding to the terminal device is level 1; when RSRP3 ≤ RSRP < RSRP2, the CE level corresponding to the terminal device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0224] When the first CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the network device, the first CE level better conforms to the scenario where the terminal device is located and has higher accuracy; when the first CE level is the CE level specified by the network device when the RRC connection is released, the CE level can be specified according to actual requirements without performing RSRP measurement.

[0225] In some embodiments, the second CE level is a CE level obtained by increasing a preset level from the first CE level; or, the second CE level is a CE level determined by the terminal device based on an RSRP measurement result and an RSRP threshold value configured by the network device.

[0226] In some embodiments, the second CE level is a CE level that is one level higher than the first CE level, for example, the first CE level is level 1 and the second CE level is level 2; or, the second CE level is a CE level that is two levels higher than the first CE level, with an upper limit of level 2, for example, the first CE level is level 0 and the second CE level is level 2, or, the first CE level is level 1 and the second CE level is level 2.

[0227] In some embodiments, the second CE level is a CE level determined by the terminal device based on the current RSRP measurement result and the RSRP threshold value configured by the network device. The determination method is referred to above and will not be repeated here.

[0228] When the second CE level is a CE level obtained by adding a preset level to the first CE level, RSRP measurement is not required and the implementation is simple; when the second CE level is a CE level determined by the terminal device based on the RSRP measurement results and the RSRP threshold value configured by the network device, the second CE level is more in line with the scenario in which the terminal device is located and has higher accuracy.

[0229] In some embodiments, the first timer is a timer started when the terminal device uses the first type of PUSCH resource to transmit the first information, and the first timer is used to limit the time for transmitting the first information.

[0230] By using a timer to determine whether the transmission of the first information fails, the implementation is simple and the control is convenient.

[0231] For the second scenario: the first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0232] In some embodiments, the first condition includes: occurrence of a first event.

[0233] Figure 7 is a schematic diagram of a transmission mode conversion method provided by an exemplary embodiment of the present application. The network device is preconfigured with multiple PUSCH resources and PURs. White squares indicate PUSCH resources, and squares filled with diagonal lines indicate PURs. The PUSCH resources corresponding to different CE levels may have the same or different periods. In this embodiment, the same period is used as an example for illustration.

[0234] For example, taking the PUSCH resource corresponding to CE level 2 (CE 2) as an example, the number of repetitions is 4, that is, after transmitting the first message, the first message is repeatedly transmitted three times. When the first event occurs, the transmission mode of the first information is switched from using PUR transmission to using pre-configured PUSCH resources.

[0235] In some embodiments, the first event includes at least one of the following: a second timer timeout; a network device indicating a PUR transmission failure; a network device indicating a PUR transmission termination; wherein the second timer is used to limit the PUR transmission time.

[0236] In some embodiments, the second timer is a timer started by the terminal device when using PUR transmission, and the second timer is used to limit the time of PUR transmission. The operation principle of the second timer is the same as that of the first timer, which will not be repeated here.

[0237] In some embodiments, the method further includes: configuring a first indication signaling, where the first indication signaling is used to indicate a PUR transmission failure or termination.

[0238] In some embodiments, the first indication signaling includes at least one of PDCCH, MAC CE, and RRC signaling.

[0239] Figure 11 shows a schematic diagram of a method for converting a transmission mode provided by an exemplary embodiment of the present application. After the terminal device uses PUR transmission, the network device configures a first indication signaling, which is used to indicate that the PUR transmission fails or is terminated.

[0240] In some embodiments, the first transmission field in the first indication signaling is used to indicate PUR transmission failure or termination. For example, the first transmission field takes a value of 00 to indicate PUR transmission failure; the first transmission field takes a value of 01 to indicate PUR transmission termination.

[0241] In some embodiments, the method further includes: configuring a PUR, wherein the PUR is used by the terminal device to transmit the PUR. As shown in FIG11 , the network device configures the PUR, and the terminal device uses the PUR for transmission.

[0242] For the third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0243] In some embodiments, the first condition includes: occurrence of a second event.

[0244] Figure 8 is a schematic diagram of a transmission mode conversion method provided by an exemplary embodiment of the present application. The network device is preconfigured with multiple PUSCH resources and EDT resources. White squares are used to indicate PUSCH resources, and squares filled with crosses are used to indicate EDT resources. The periods of PUSCH resources corresponding to different CE levels may be the same or different. In the embodiment of the present application, the same period is used as an example for illustration.

[0245] For example, taking the PUSCH resource corresponding to CE level 1 (CE 1) as an example, the number of repetitions is 3, that is, after transmitting the first message, the first message is repeatedly transmitted twice. In the event of the second event, the transmission mode of the first message is switched from using the preconfigured PUSCH resource to using the EDT resource.

[0246] In some embodiments, the second event includes at least one of the following: a third timer times out; the network device indicates that the transmission of the first information fails; the network device indicates that the transmission of the first information is terminated; the number of times the first information is transmitted reaches a second transmission number;

[0247] The third timer is used to limit the time for transmitting the first information, and the second number of transmission attempts is the maximum number of transmission attempts corresponding to the PUSCH resource.

[0248] In the event of a second event, the transmission mode is changed. For example, when the second event is the timeout of the third timer, the implementation is simple and easy to control. When the second event is the network device indicating that the transmission of the first information has failed or terminated, the conversion is performed according to the indication signaling, the operation is accurate, and there is no need to introduce other mechanisms. When the second event is that the number of times the first information is transmitted reaches the second number of transmissions, it is easy to monitor, and when the number of times the first information is transmitted has reached the maximum number of transmission attempts, the first information is likely to fail to be transmitted, which meets the timing for changing the transmission mode.

[0249] In some embodiments, the third timer is a timer started when the terminal device uses the preconfigured PUSCH resource to transmit the first information. The use principle of the third timer is the same as that of the first timer and will not be repeated here.

[0250] In some embodiments, the method further includes: configuring a second indication signaling, the second indication signaling being used to indicate failure or termination of transmission of the first information.

[0251] In some embodiments, the second transmission field in the second indication signaling is used to indicate the failure or termination of transmission of the first information. For example, the second transmission field takes a value of 00 to indicate the failure of transmission of the first information; the second transmission field takes a value of 01 to indicate the termination of transmission of the first information.

[0252] FIG. 12 shows a schematic diagram of a method for converting a transmission mode provided by an exemplary embodiment of the present application. After the terminal device uses the pre-configured PUSCH resource for transmission, the network device configures a second indication signaling, and the first indication signaling is used to indicate that the transmission of the first information fails or terminates.

[0253] In some embodiments, the method further includes: configuring a second transmission count, where the second transmission count is the maximum number of transmission attempts corresponding to the PUSCH resource.

[0254] In some embodiments, the method further includes: configuring an EDT resource, where the EDT resource is related to a third CE level.

[0255] FIG. 13 shows a schematic diagram of a method for converting a transmission mode provided by an exemplary embodiment of the present application. Taking the second event as an example where the number of times of transmitting the first information reaches the second transmission count. The network device configures the second transmission count, and the second transmission count includes the initial transmission, that is, the maximum number of transmission attempts corresponding to the PUSCH resource is n + 1 times, where n is a positive integer.

[0256] When the first transmission of the terminal device using the pre-configured PUSCH resource fails, the first retransmission is performed. After the first retransmission fails, the second retransmission is performed until the retransmission is performed n times, and the terminal device switches to using the EDT resource pre-configured by the network device for transmission.

[0257] In some embodiments, the third CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the network device; or, the third CE level is the CE level associated with the last transmission of the first information in the case of failure to transmit the first information; or, the third CE level is the CE level obtained by adding a preset level to the CE level associated with the last transmission of the first information in the case of failure to transmit the first information.

[0258] In some embodiments, the terminal device obtains the signal quality of the CRS by measuring the CRS, and the measurement result of the CRS is represented by RSRP.

[0259] Exemplarily, the network device configures three RSRP threshold values, RSRP1, RSRP2, and RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the CE level corresponding to the terminal device is level 0; when RSRP2 ≤ RSRP < RSRP1, the CE level corresponding to the terminal device is level 1; when RSRP3 ≤ RSRP < RSRP2, the CE level corresponding to the terminal device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0260] In some embodiments, if the transmission of the first information fails, the CE level associated with the last transmission of the first information is level m, and the third CE level is level m, where m is 0, 1, or 2. For example, if the CE level associated with the last transmission of the first information is level 1, then the third CE level is level 1.

[0261] In some embodiments, in the event of a failure in transmitting the first information, the third CE level is a CE level that is one level higher than the CE level associated with the last time the first information was transmitted, for example, the CE level associated with the last time the first information was transmitted was level 1, and the third CE level was level 2; or, the third CE level is a CE level that is two levels higher than the CE level associated with the last time the first information was transmitted, with an upper limit of level 2, for example, the CE level associated with the last time the first information was transmitted was level 0, and the third CE level was level 2, or, the CE level associated with the last time the first information was transmitted was level 1, and the third CE level was level 2.

[0262] When the third CE level is the CE level determined by the terminal device based on the RSRP measurement results and the RSRP threshold value configured by the network device, the third CE level is more in line with the scenario in which the terminal device is located and has higher accuracy; when the third CE level is the CE level associated with the last transmission of the first information, RSRP measurement is not required and the implementation is simple; when the third CE level is a CE level with a preset level added to the CE level associated with the last transmission of the first information, it is more reasonable and can find the appropriate CE level faster.

[0263] In some embodiments, the transmission mode conversion methods of the first situation and the second situation can be used in combination, that is, when a first event occurs, the transmission mode of the first information is converted from using PUR transmission to using preconfigured first type of PUSCH resource transmission, and then when the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using preconfigured first type of PUSCH resource transmission to using preconfigured second type of PUSCH resource transmission.

[0264] In some embodiments, the transmission mode conversion methods of the first situation and the third situation can be used in combination, that is, when the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission; in the event of a second event, the transmission mode of the first information is converted from using the preconfigured second type of PUSCH resource transmission to using EDT resources transmission.

[0265] In some embodiments, the transmission mode conversion methods of the second and third situations can be used in combination, that is, when the first event occurs, the transmission mode of the first information is converted from using PUR transmission to using pre-configured PUSCH resources for transmission, and then when the second event occurs, the transmission mode of the first information is converted from using pre-configured PUSCH resources for transmission to using EDT resources for transmission.

[0266] The embodiments of the present application do not limit the combined use of the above-mentioned transmission mode conversion methods. For specific implementation details, please refer to the above-mentioned embodiments and will not be repeated here.

[0267] To sum up, the method provided in this embodiment receives first information transmitted using a first uplink transmission mode; receives first information transmitted using a second uplink transmission mode; wherein the second uplink transmission mode is an uplink transmission mode determined by a terminal device in an idle state or an inactive state when a first condition is met, and the first uplink transmission mode or the second uplink transmission mode includes: using pre-configured PUSCH resources for transmission, so that when the first information fails to be transmitted, different uplink transmission modes are converted, so that the network device can receive the first information, thereby improving the transmission possibility of the terminal device in an idle state or an inactive state, and increasing the success rate of uplink transmission in an idle state or an inactive state.

[0268] In the above embodiments, the embodiment corresponding to FIG. 5 and the embodiment corresponding to FIG. 10 may be implemented separately or in combination, and this application does not limit this.

[0269] FIG14 is a block diagram of a transmission mode conversion device provided by an exemplary embodiment of the present application. The device can be implemented as a terminal device or as a part of a terminal device through software or hardware or a combination of both. The device includes:

[0270] The conversion module 1410 is configured to convert the transmission mode of the first information from the first uplink transmission mode to the second uplink transmission mode when the first condition is met; wherein the first uplink transmission mode or the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0271] In one possible design of this embodiment, transmission may be understood as at least one of direct transmission, direct transmission of message 3, transmission without scheduling, transmission without message 1, transmission without RAR, transmission without sending message 1, and transmission without receiving RAR. Message 1 refers to message 1 during a random access procedure, and RAR refers to message 2 during a random access procedure.

[0272] In a possible design of this embodiment, the use of preconfigured PUSCH resource transmission can be understood as: using at least one of contention-based PUSCH resource transmission, using message 3 to directly transmit resource transmission, using PUSCH resource transmission without message 1, and using PUSCH resource transmission without RAR.

[0273] In a possible design of this embodiment, the first condition can be understood as at least one of a conversion condition, a handover condition, a transformation condition, and a fallback condition.

[0274] In a possible design of this embodiment, the reliability of the second uplink transmission mode is higher than the reliability of the first uplink transmission mode.

[0275] In a possible design of this embodiment, with the same amount of data, the uplink resources used by the second uplink transmission mode are better than or more than the uplink resources used by the first uplink transmission mode.

[0276] In a possible design of this embodiment, the first uplink transmission mode and the second uplink transmission mode are both direct transmission modes in which the transmission mode conversion device is in an idle state or an inactive state and does not require Message 1 and / or RAR.

[0277] In one possible design of this embodiment, the PUSCH resource is a contention-based PUSCH resource. For example, in a contention-based random access mechanism, the PUSCH resource is a resource used to transmit message 3 (msg3); for another example, in a message 3 direct transmission mechanism, the PUSCH resource is a resource used to directly transmit message 3.

[0278] In a possible design of this embodiment, the first information includes first signaling; or, the first information includes first signaling and first data.

[0279] In a possible design of this embodiment, the first signaling includes at least one of the following: an RRC connection establishment request (RRCSetupRequest), an RRC connection resumption request (RRCConnectionResumeRequest), and an early data request (EarlyDataRequest).

[0280] Among them, the RRC connection establishment request is used to request the establishment of an RRC connection. The transmission mode conversion device sends the RRC connection establishment request to the network device to initiate the connection process; the RRC connection recovery request is used to request the recovery of the RRC connection. When the transmission mode conversion device is in a non-connected state and hopes to restore the connection, the request is sent to the network device; the early data request is used to request partial data transmission before the RRC connection is established, so as to improve the connection speed and optimize the transmission performance.

[0281] In a possible design of this embodiment, the first uplink transmission mode and the second uplink transmission mode include at least one of the following three situations:

[0282] The first scenario: the first uplink transmission mode includes: using a pre-configured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a pre-configured second type of PUSCH resource for transmission.

[0283] Second scenario: the first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0284] The third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0285] In a possible design of this embodiment, PUSCH resources (including first-type PUSCH resources and second-type PUSCH resources) are resources configured by a network device.

[0286] For the first scenario: the first uplink transmission mode includes: using a preconfigured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a preconfigured second type of PUSCH resource for transmission.

[0287] In a possible design of this embodiment, the first condition includes: the number of times the transmission mode conversion device transmits the first information reaches a first transmission number, and the first transmission number is the maximum number of transmission attempts corresponding to the first type of PUSCH resources.

[0288] When the number of times the transmission mode conversion device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission.

[0289] Since there is competition between devices switching transmission modes when using a PUSCH resource transmission mechanism (eg, a message 3 direct transmission mechanism), allowing multiple retransmissions can increase the probability of resolving contention conflicts.

[0290] In a possible design of this embodiment, the first transmission number is configured by the network device.

[0291] Configuring the first transmission number through a network device can support a variety of configuration methods, thereby performing configuration according to actual needs.

[0292] In one possible design of this embodiment, the maximum number of transmission attempts (maximum retransmission times) includes the initial transmission. For example, if the initial transmission fails, the maximum number of transmission attempts is 4, then a maximum of 3 retransmissions are allowed. In this embodiment of the present application, the maximum number of transmission attempts includes the initial transmission as an example for description.

[0293] In one possible design of this embodiment, the maximum number of transmission attempts does not include the initial transmission. For example, if the initial transmission fails and the maximum number of transmission attempts is four, then a maximum of four retransmissions are allowed. In this case, the maximum number of transmission attempts can be understood as the maximum number of retransmission attempts.

[0294] In a possible design of this embodiment, the first repetition number is smaller than the second repetition number, the first repetition number is the repetition number corresponding to the first type of PUSCH resources, and the second repetition number is the repetition number corresponding to the second type of PUSCH resources.

[0295] For example, a transmission or retransmission includes multiple repetitions of the same information. The number of repetitions refers to the number of times the same information is repeated in a transmission or retransmission. For example, if the string to be transmitted is 0110 and the number of repetitions is 3, the transmitted string is 011001100110.

[0296] Since the channel quality of the transmission mode conversion device may continue to deteriorate due to various reasons, for example, in a non-terrestrial network (NTN) scenario, the channel quality deteriorates due to satellite provision, using PUSCH resources corresponding to more repetition times for transmission can improve the success rate of transmission.

[0297] In a possible design of this embodiment, the transmission module 1420 is configured to retransmit the first information when transmission of the first information fails using a preconfigured first type of PUSCH resource.

[0298] Possible situations in which the transmission of the first information fails include at least one of the following: the first timer times out; the network device indicates that the transmission of the first information fails or is terminated; the transmission of the first information is interfered with by other devices; multiple devices attempt to transmit the first information simultaneously.

[0299] In a possible design of this embodiment, the first timer is a timer started by the transmission mode conversion device when using the first type of PUSCH resource to transmit the first information, and the first timer is used to limit the time for transmitting the first information.

[0300] In a possible design of this embodiment, the transmission module 1420 is used to retransmit the first information when the first timer expires.

[0301] Exemplarily, the first timer limits the time for transmitting the first information to 100 milliseconds, and the moment when the transmission mode conversion device starts transmitting the first information using the first type of PUSCH resource is the starting moment. When the first timer exceeds 100 milliseconds, the first information is retransmitted.

[0302] By using a timer to determine whether the transmission of the first information fails, the implementation is simple and the control is convenient.

[0303] In a possible design of this embodiment, the transmission module 1420 is further configured to, if the i-th retransmission fails, perform an (i+1)-th retransmission until the number of transmissions of the first information reaches a first transmission number;

[0304] The first number of transmission attempts is the maximum number of transmission attempts corresponding to the first type of PUSCH resources, and i is a positive integer.

[0305] By retransmitting the first information when the transmission of the first information fails, and continuing to retransmit the first information when the retransmission fails until the number of transmissions of the first information reaches the first number of transmissions, the transmission success rate of the first information is improved.

[0306] In a possible design of this embodiment, the first type of PUSCH resources are associated with a first CE level, and the second type of PUSCH resources are associated with a second CE level.

[0307] There are three CE ratings: Level 0, Level 1, and Level 2, corresponding to resistance to signal attenuation of 144dB, 154dB, and 164dB, respectively. The number of message repetitions between network equipment and the transmission mode converter is determined by the CE rating of the transmission mode converter.

[0308] In a possible design of this embodiment, the first CE level is the CE level determined by the transmission mode conversion device based on the reference signal receiving power (RSRP) measurement result and the RSRP threshold value configured by the network device; or, the first CE level is the CE level specified by the network device when the RRC connection is released.

[0309] In a possible design of this embodiment, the transmission mode conversion device obtains the signal quality of a cell-specific reference signal (CRS) by measuring the CRS, and the measurement result of the CRS is represented by RSRP.

[0310] Exemplarily, the network device configures 3 RSRP threshold values, RSRP1, RSRP2, and RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the CE level corresponding to the transmission mode conversion device is level 0; when RSRP2 ≤ RSRP < RSRP1, the CE level corresponding to the transmission mode conversion device is level 1; when RSRP3 ≤ RSRP < RSRP2, the CE level corresponding to the transmission mode conversion device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0311] When the first CE level is the CE level determined by the transmission mode conversion device according to the RSRP measurement result and the RSRP threshold value configured by the network device, the first CE level is more in line with the scenario where the transmission mode conversion device is located and has higher accuracy; when the first CE level is the CE level specified by the network device when the RRC connection is released, the CE level can be specified according to actual requirements without performing RSRP measurement.

[0312] In a possible design of this embodiment, the second CE level is the CE level obtained by adding a preset level to the first CE level; or, the second CE level is the CE level determined by the transmission mode conversion device according to the RSRP measurement result and the RSRP threshold value configured by the network device.

[0313] In a possible design of this embodiment, the second CE level is the CE level obtained by adding one level to the first CE level. For example, if the first CE level is level 1, the second CE level is level 2; or, the second CE level is the CE level obtained by adding two levels to the first CE level, with an upper limit of level 2. For example, if the first CE level is level 0, the second CE level is level 2, or if the first CE level is level 1, the second CE level is level 2.

[0314] In a possible design of this embodiment, the second CE level is the CE level determined by the transmission mode conversion device according to the current RSRP measurement result and the RSRP threshold value configured by the network device. The determination method is as described above and will not be elaborated here.

[0315] When the second CE level is the CE level obtained by adding a preset level to the first CE level, RSRP measurement is not required and the implementation is simple; when the second CE level is the CE level determined by the transmission mode conversion device according to the RSRP measurement result and the RSRP threshold value configured by the network device, the second CE level is more in line with the scenario where the transmission mode conversion device is located and has higher accuracy.

[0316] For the second case: The first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0317] In a possible design of this embodiment, the first condition includes: occurrence of a first event.

[0318] In a possible design of this embodiment, the first event includes at least one of the following: the second timer times out; the network device indicates that the PUR transmission fails; the network device indicates that the PUR transmission is terminated; wherein the second timer is used to limit the time of PUR transmission.

[0319] In a possible design of this embodiment, the network device indicates the failure or termination of PUR transmission by configuring indication signaling, and the indication signaling includes at least one of the physical downlink control channel (Physical Downlink Control Channel, PDCCH), the medium access control control element (Medium Access Control Control Element, MAC CE), and RRC signaling.

[0320] When the first event occurs, the transmission mode is changed. For example, when the first event is the timeout of the second timer, the implementation is simple and easy to control. When the first event is the network device indicating that the PUR transmission has failed or terminated, the conversion is performed according to the indication signaling. The operation is accurate and there is no need to introduce other mechanisms.

[0321] In one possible design of this embodiment, the preconfigured PUSCH resources are associated with the fourth CE level.

[0322] In a possible design of this embodiment, the fourth CE level is the CE level determined by the transmission mode conversion device according to the RSRP measurement result and the RSRP threshold value configured by the network device. The specific implementation details refer to the embodiment of the first case and are not repeated here.

[0323] In one possible design of this embodiment, the second timer is a timer started by the transmission mode conversion device when using PUR transmission, and the second timer is used to limit the time of PUR transmission. The operation principle of the second timer is the same as that of the first timer and will not be repeated here.

[0324] PUR transmission failure may be due to deteriorating channel quality, and the PUR configured by the network device cannot adapt to the deteriorating channel quality. In this case, it falls back to using PUSCH resources for transmission (for example, direct transmission of message 3). The PUSCH resource transmission mechanism can select PUSCH resources that adapt to the channel quality, improving the transmission success rate.

[0325] For the third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0326] In a possible design of this embodiment, the first condition includes: a second event occurs.

[0327] In a possible design of this embodiment, the second event includes at least one of the following: a third timer times out; the network device indicates that the transmission of the first information fails; the network device indicates that the transmission of the first information is terminated; the number of times the first information is transmitted reaches a second transmission number;

[0328] The third timer is used to limit the time for transmitting the first information, and the second number of transmission attempts is the maximum number of transmission attempts corresponding to the PUSCH resource.

[0329] In the event of a second event, the transmission mode is changed. For example, when the second event is the timeout of the third timer, the implementation is simple and easy to control. When the second event is the network device indicating that the transmission of the first information has failed or terminated, the conversion is performed according to the indication signaling, the operation is accurate, and there is no need to introduce other mechanisms. When the second event is that the number of times the first information is transmitted reaches the second number of transmissions, it is easy to monitor, and when the number of times the first information is transmitted has reached the maximum number of transmission attempts, the first information is likely to fail to be transmitted, which meets the timing for changing the transmission mode.

[0330] In a possible design of this embodiment, the second transmission number is configured by the network device.

[0331] Configuring the second transmission number through a network device can support a variety of configuration methods, thereby performing configuration according to actual needs.

[0332] In one possible design of this embodiment, the third timer is a timer started by the transmission mode switching apparatus when transmitting the first information using a preconfigured PUSCH resource. The third timer is used to limit the time for transmitting the first information. The operation principle of the third timer is the same as that of the first timer and is not further described here.

[0333] In a possible design of this embodiment, EDT resources are associated with the third CE level.

[0334] In a possible design of this embodiment, the third CE level is a CE level determined by the transmission mode conversion device based on the RSRP measurement result and the RSRP threshold value configured by the network device; or, the third CE level is the CE level associated with the last transmission of the first information when the transmission of the first information fails; or, the third CE level is a CE level with a preset level added to the CE level associated with the last transmission of the first information when the transmission of the first information fails.

[0335] In a possible design of this embodiment, the transmission mode conversion device obtains the signal quality of the CRS by measuring the CRS, and the measurement result of the CRS is represented by the RSRP.

[0336] Exemplarily, the network device configures three RSRP threshold values, RSRP1, RSRP2, and RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the corresponding CE level of the transmission mode conversion device is level 0; when RSRP2 ≤ RSRP < RSRP1, the corresponding CE level of the transmission mode conversion device is level 1; when RSRP3 ≤ RSRP < RSRP2, the corresponding CE level of the transmission mode conversion device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0337] In a possible design of this embodiment, in the case where the transmission of the first information fails, the CE level associated with the last transmission of the first information is level m, and the third CE level is level m, where m takes a value of 0 or 1 or 2. For example, if the CE level associated with the last transmission of the first information is level 1, then the third CE level is level 1.

[0338] In a possible design of this embodiment, in the case where the transmission of the first information fails, the third CE level is the CE level that is one level higher than the CE level associated with the last transmission of the first information. For example, if the CE level associated with the last transmission of the first information is level 1, the third CE level is level 2; or, the third CE level is the CE level that is two levels higher than the CE level associated with the last transmission of the first information, with an upper limit of level 2. For example, if the CE level associated with the last transmission of the first information is level 0, the third CE level is level 2, or if the CE level associated with the last transmission of the first information is level 1, the third CE level is level 2.

[0339] When the third CE level is the CE level determined by the transmission mode conversion device according to the RSRP measurement result and the RSRP threshold values configured by the network device, the third CE level is more in line with the scenario where the transmission mode conversion device is located and has higher accuracy; when the third CE level is the CE level associated with the last transmission of the first information, no RSRP measurement is required and the implementation is simple; when the third CE level is the CE level that is increased by a preset level from the CE level associated with the last transmission of the first information, it is more reasonable and can find a suitable CE level faster.

[0340] The failure of transmission using PUSCH resources may be due to incorrect PUSCH resource configuration. Since transmission using PUSCH resources (such as direct transmission of message 3) is not suitable for dynamic scheduling, PUSCH resources cannot be changed after the configuration error. After switching to transmission using EDT resources, dynamic scheduling during the random access process can be used to improve the transmission situation and increase the transmission success rate.

[0341] In a possible design of this embodiment, the first situation and the second situation can be used in combination, that is, when a first event occurs, the transmission mode of the first information is converted from using PUR transmission to using preconfigured first type of PUSCH resource transmission, and then when the number of times the transmission mode conversion device transmits the first information reaches the first number of transmissions, the transmission mode of the first information is converted from using preconfigured first type of PUSCH resource transmission to using preconfigured second type of PUSCH resource transmission.

[0342] In a possible design of this embodiment, the first situation and the third situation can be used in combination, that is, when the number of times the transmission mode conversion device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission; when the second event occurs, the transmission mode of the first information is converted from using the preconfigured second type of PUSCH resource transmission to using EDT resources transmission.

[0343] In a possible design of this embodiment, the second situation and the third situation can be used in combination, that is, when the first event occurs, the transmission mode of the first information is converted from using PUR transmission to using pre-configured PUSCH resources for transmission, and then when the second event occurs, the transmission mode of the first information is converted from using pre-configured PUSCH resources for transmission to using EDT resources for transmission.

[0344] The embodiments of the present application do not limit the combined use of the above-mentioned situations. For specific implementation details, please refer to the above-mentioned embodiments and will not be repeated here.

[0345] In this embodiment, the transmission module 1420 can be divided into multiple transmission modules, such as a first transmission module and a second transmission module. The first transmission module is configured to retransmit the first information if the transmission of the first information using the preconfigured first type of PUSCH resources fails, and the second transmission module is configured to perform the (i+1)th retransmission if the i-th retransmission fails, until the number of transmissions of the first information reaches the first number of transmissions; or the first transmission module is configured to perform the (i+1)th retransmission if the i-th retransmission fails, until the number of transmissions of the first information reaches the first number of transmissions, and the second transmission module is configured to retransmit the first information if the transmission of the first information using the preconfigured first type of PUSCH resources fails. This embodiment does not limit the functions of the different transmission modules.

[0346] This embodiment is described by taking one conversion module 1410 and one transmission module 1420 as an example, and the number of the conversion modules 1410 and the transmission modules 1420 is not limited.

[0347] For an introduction to the functions of the conversion module 1410 , please refer to the content of step 510 in the embodiment of FIG. 5 .

[0348] For an introduction to the functions of the transmission module 1420 , please refer to the content of step 510 in the embodiment of FIG. 5 .

[0349] FIG15 is a block diagram of an information receiving device provided by an exemplary embodiment of the present application. The device can be implemented as a network device or as a part of a network device through software or hardware or a combination of both. The device includes:

[0350] The receiving module 1510 is configured to receive first information transmitted using a first uplink transmission mode; and receive first information transmitted using a second uplink transmission mode.

[0351] The second uplink transmission mode is an uplink transmission mode determined by a terminal device in an idle state or an inactive state when the first condition is met. The first uplink transmission mode or the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0352] In one possible design of this embodiment, transmission may be understood as at least one of direct transmission, direct transmission of message 3, transmission without scheduling, transmission without message 1, transmission without RAR, transmission without sending message 1, and transmission without receiving RAR. Message 1 refers to message 1 during a random access procedure, and RAR refers to message 2 during a random access procedure.

[0353] In a possible design of this embodiment, the first information includes first signaling; or, the first information includes first signaling and first data.

[0354] In a possible design of this embodiment, the first signaling includes at least one of the following: an RRC connection establishment request (RRCSetupRequest), an RRC connection resumption request (RRCConnectionResumeRequest), and an early data request (EarlyDataRequest).

[0355] Among them, the RRC connection establishment request is used to request the establishment of an RRC connection. The terminal device sends the RRC connection establishment request to the information receiving device to initiate the connection process; the RRC connection recovery request is used to request the restoration of the RRC connection. When the terminal device is in a non-connected state and hopes to restore the connection, the request is sent to the information receiving device; the early data request is used to request partial data transmission before the RRC connection is established, so as to improve the connection speed and optimize the transmission performance.

[0356] In a possible design of this embodiment, the use of preconfigured PUSCH resource transmission can be understood as: using at least one of contention-based PUSCH resource transmission, using message 3 to directly transmit resource transmission, using PUSCH resource transmission without message 1, and using PUSCH resource transmission without RAR.

[0357] In a possible design of this embodiment, the first condition can be understood as at least one of a conversion condition, a handover condition, a transformation condition, and a fallback condition.

[0358] In a possible design of this embodiment, the reliability of the second uplink transmission mode is higher than the reliability of the first uplink transmission mode.

[0359] In a possible design of this embodiment, with the same amount of data, the uplink resources used by the second uplink transmission mode are better than or more than the uplink resources used by the first uplink transmission mode.

[0360] In a possible design of this embodiment, the first uplink transmission mode and the second uplink transmission mode are both direct transmission modes when the terminal device is in an idle state or an inactive state, without the need for message 1 and / or RAR.

[0361] In one possible design of this embodiment, the PUSCH resource is a contention-based PUSCH resource. For example, in a contention-based random access mechanism, the PUSCH resource is a resource used to transmit message 3 (msg3); for another example, in a message 3 direct transmission mechanism, the PUSCH resource is a resource used to directly transmit message 3.

[0362] In a possible design of this embodiment, the first uplink transmission mode and the second uplink transmission mode include at least one of the following three situations:

[0363] The first scenario: the first uplink transmission mode includes: using a pre-configured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a pre-configured second type of PUSCH resource for transmission.

[0364] Second scenario: the first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0365] The third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0366] In a possible design of this embodiment, PUSCH resources (including first-type PUSCH resources and second-type PUSCH resources) are resources configured by the information receiving apparatus.

[0367] For the first scenario: the first uplink transmission mode includes: using a preconfigured first type of PUSCH resource for transmission; the second uplink transmission mode includes: using a preconfigured second type of PUSCH resource for transmission.

[0368] In a possible design of this embodiment, the first condition includes: the number of times the terminal device transmits the first information reaches a first transmission number, and the first transmission number is the maximum number of transmission attempts corresponding to the first type of PUSCH resource.

[0369] When the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission.

[0370] Since there is contention between terminal devices when using a PUSCH resource transmission mechanism (such as the message 3 direct transmission mechanism), allowing multiple retransmissions can increase the probability of resolving contention conflicts.

[0371] In one possible design of this embodiment, the maximum number of transmission attempts (maximum retransmission times) includes the initial transmission. For example, if the initial transmission fails, the maximum number of transmission attempts is 4, then a maximum of 3 retransmissions are allowed. In this embodiment of the present application, the maximum number of transmission attempts includes the initial transmission as an example for description.

[0372] In one possible design of this embodiment, the maximum number of transmission attempts does not include the initial transmission. For example, if the initial transmission fails and the maximum number of transmission attempts is four, then a maximum of four retransmissions are allowed. In this case, the maximum number of transmission attempts can be understood as the maximum number of retransmission attempts.

[0373] In a possible design of this embodiment, the first repetition number is smaller than the second repetition number, the first repetition number is the repetition number corresponding to the first type of PUSCH resources, and the second repetition number is the repetition number corresponding to the second type of PUSCH resources.

[0374] For example, a transmission or retransmission includes multiple repetitions of the same information. The number of repetitions refers to the number of times the same information is repeated in a transmission or retransmission. For example, if the string to be transmitted is 0110 and the number of repetitions is 3, the transmitted string is 011001100110.

[0375] Since the channel quality of the terminal device may continue to deteriorate due to various reasons, such as the deterioration of the channel quality caused by satellite in the non-terrestrial network (NTN) scenario, using PUSCH resources corresponding to more repetitions for transmission can improve the success rate of transmission.

[0376] In a possible design of this embodiment, the configuration module 1520 is used to configure a first number of transmission times, where the first number of transmission times is a maximum number of transmission attempts corresponding to the first type of PUSCH resources.

[0377] Configuring the first number of transmission times through the information receiving device can support a variety of configuration methods, so that configuration can be performed according to actual needs.

[0378] In a possible design of this embodiment, the first type of PUSCH resources are associated with a first CE level, and the second type of PUSCH resources are associated with a second CE level.

[0379] There are three CE ratings: Level 0, Level 1, and Level 2, corresponding to resistance to signal attenuation of 144dB, 154dB, and 164dB, respectively. The number of message repetitions between the receiving device and the terminal device will be determined based on the terminal device's CE rating.

[0380] In a possible design of this embodiment, the first CE level is the CE level determined by the terminal device based on the RSRP measurement result and the RSRP threshold value configured by the information receiving device; or, the first CE level is the CE level specified by the information receiving device when the RRC connection is released.

[0381] In a possible design of this embodiment, the terminal device obtains the signal quality of the CRS by measuring the CRS, and the measurement result of the CRS is represented by RSRP.

[0382] Exemplarily, the information receiving device configures 3 RSRP threshold values, RSRP1, RSRP2, and RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the corresponding CE level of the terminal device is level 0; when RSRP2 ≤ RSRP < RSRP1, the corresponding CE level of the terminal device is level 1; when RSRP3 ≤ RSRP < RSRP2, the corresponding CE level of the terminal device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0383] When the first CE level is the CE level determined by the terminal device based on the RSRP measurement result and the RSRP threshold value configured by the information receiving device, the first CE level is more in line with the scenario where the terminal device is located and has higher accuracy; when the first CE level is the CE level specified by the information receiving device when the RRC connection is released, the CE level can be specified according to actual requirements without performing an RSRP measurement.

[0384] In a possible design of this embodiment, the second CE level is the CE level obtained by adding a preset level to the first CE level; or, the second CE level is the CE level determined by the terminal device based on the RSRP measurement result and the RSRP threshold value configured by the information receiving device.

[0385] In a possible design of this embodiment, the second CE level is the CE level obtained by adding one level to the first CE level. For example, if the first CE level is level 1, the second CE level is level 2; or, the second CE level is the CE level obtained by adding two levels to the first CE level, with an upper limit of level 2. For example, if the first CE level is level 0, the second CE level is level 2, or if the first CE level is level 1, the second CE level is level 2.

[0386] In a possible design of this embodiment, the second CE level is the CE level determined by the terminal device based on the current RSRP measurement result and the RSRP threshold value configured by the information receiving device, and the determination method refers to the above and will not be elaborated here.

[0387] When the second CE level is the CE level obtained by adding a preset level to the first CE level, no RSRP measurement is required and the implementation is simple; when the second CE level is the CE level determined by the terminal device based on the RSRP measurement result and the RSRP threshold value configured by the information receiving device, the second CE level is more in line with the scenario where the terminal device is located and has higher accuracy.

[0388] In a possible design of this embodiment, the first timer is a timer started by the terminal device when transmitting the first information using the first type of PUSCH resource, and the first timer is used to limit the time for transmitting the first information.

[0389] By using a timer to determine whether the transmission of the first information fails, the implementation is simple and the control is convenient.

[0390] For the second scenario: the first uplink transmission mode includes: using PUR for transmission; the second uplink transmission mode includes: using preconfigured PUSCH resources for transmission.

[0391] In a possible design of this embodiment, the first condition includes: occurrence of a first event.

[0392] In a possible design of this embodiment, the first event includes at least one of the following: the second timer times out; the information receiving device indicates that the PUR transmission fails; the information receiving device indicates that the PUR transmission is terminated; wherein the second timer is used to limit the time of PUR transmission.

[0393] In a possible design of this embodiment, the second timer is a timer started by the terminal device when using PUR transmission, and the second timer is used to limit the time of PUR transmission. The operation principle of the second timer is the same as that of the first timer and will not be repeated here.

[0394] In a possible design of this embodiment, the configuration module 1520 is further used to configure a first indication signaling, where the first indication signaling is used to indicate that the PUR transmission fails or is terminated.

[0395] In a possible design of this embodiment, the first indication signaling includes at least one of PDCCH, MAC CE, and RRC signaling.

[0396] Figure 11 shows a schematic diagram of a method for converting a transmission mode provided by an exemplary embodiment of the present application. After the terminal device uses PUR transmission, the information receiving device configures a first indication signaling, which is used to indicate that the PUR transmission fails or is terminated.

[0397] In a possible design of this embodiment, the first transmission field in the first indication signaling is used to indicate the failure or termination of PUR transmission. For example, the value of the first transmission field is 00, which is used to indicate the failure of PUR transmission; the value of the first transmission field is 01, which is used to indicate the termination of PUR transmission.

[0398] In a possible design of this embodiment, the configuration module 1520 is further used to configure a PUR, which is used by the terminal device to transmit the PUR. As shown in FIG11 , the information receiving device configures the PUR, and the terminal device uses the PUR for transmission.

[0399] For the third scenario: the first uplink transmission mode includes: using pre-configured PUSCH resources for transmission; the second uplink transmission mode includes: using EDT resources for transmission.

[0400] In a possible design of this embodiment, the first condition includes: a second event occurs.

[0401] In a possible design of this embodiment, the second event includes at least one of the following: a third timer times out; an information receiving device indicates that transmission of the first information has failed; an information receiving device indicates that transmission of the first information has terminated; the number of times the first information has been transmitted reaches a second number of transmissions;

[0402] The third timer is used to limit the time for transmitting the first information, and the second number of transmission attempts is the maximum number of transmission attempts corresponding to the PUSCH resource.

[0403] In the event of a second event, the transmission mode is changed. For example, when the second event is the timeout of the third timer, the implementation is simple and easy to control. When the second event is that the information receiving device indicates that the transmission of the first information has failed or terminated, the conversion is performed according to the indication signaling, the operation is accurate, and there is no need to introduce other mechanisms. When the second event is that the number of times the first information is transmitted reaches the second number of transmissions, it is easy to monitor, and when the number of times the first information is transmitted has reached the maximum number of transmission attempts, the first information is likely to fail to be transmitted, which meets the timing of the need to change the transmission mode.

[0404] In a possible design of this embodiment, the third timer is a timer started when the terminal device uses the preconfigured PUSCH resource to transmit the first information. The use principle of the third timer is the same as that of the first timer and is not repeated here.

[0405] In a possible design of this embodiment, the configuration module 1520 is further used to configure a second indication signaling, where the second indication signaling is used to indicate failure or termination of transmission of the first information.

[0406] In a possible design of this embodiment, the second transmission field in the second indication signaling is used to indicate the failure or termination of transmission of the first information. For example, the value of the second transmission field is 00, which is used to indicate the failure of transmission of the first information; the value of the second transmission field is 01, which is used to indicate the termination of transmission of the first information.

[0407] Figure 12 shows a schematic diagram of a method for converting a transmission mode provided by an exemplary embodiment of the present application. After the terminal device uses the pre-configured PUSCH resource for transmission, the information receiving device configures a second indication signaling, where the first indication signaling is used to indicate failure or termination of transmission of the first information.

[0408] In a possible design of this embodiment, the configuration module 1520 is further used to configure a second number of transmission times, where the second number of transmission times is the maximum number of transmission attempts corresponding to the PUSCH resources.

[0409] In a possible design of this embodiment, the configuration module 1520 is further configured to configure EDT resources, and the EDT resources are related to the third CE level.

[0410] In a possible design of this embodiment, the third CE level is the CE level determined by the terminal device according to the RSRP measurement result and the RSRP threshold value configured by the information receiving device; or, the third CE level is the CE level associated with the last transmission of the first information in the case of failure to transmit the first information; or, the third CE level is the CE level obtained by adding a preset level to the CE level associated with the last transmission of the first information in the case of failure to transmit the first information.

[0411] In a possible design of this embodiment, the terminal device obtains the signal quality of the CRS by measuring the CRS, and the measurement result of the CRS is represented by RSRP.

[0412] Exemplarily, the information receiving device configures 3 RSRP threshold values, RSRP1, RSRP2, and RSRP3, where RSRP1 > RSRP2 > RSRP3. When RSRP ≥ RSRP1, the corresponding CE level of the terminal device is level 0; when RSRP2 ≤ RSRP < RSRP1, the corresponding CE level of the terminal device is level 1; when RSRP3 ≤ RSRP < RSRP2, the corresponding CE level of the terminal device is level 2; when RSRP < RSRP3, the reference signal quality is too low and does not correspond to a CE level.

[0413] In a possible design of this embodiment, in the case of failure to transmit the first information, the CE level associated with the last transmission of the first information is level m, and the third CE level is level m, where m takes the value of 0 or 1 or 2. For example, if the CE level associated with the last transmission of the first information is level 1, then the third CE level is level 1.

[0414] In a possible design of this embodiment, in the case of failure to transmit the first information, the third CE level is the CE level obtained by adding one level to the CE level associated with the last transmission of the first information. For example, if the CE level associated with the last transmission of the first information is level 1, the third CE level is level 2; or, the third CE level is the CE level obtained by adding two levels to the CE level associated with the last transmission of the first information, with an upper limit of level 2. For example, if the CE level associated with the last transmission of the first information is level 0, the third CE level is level 2, or if the CE level associated with the last transmission of the first information is level 1, the third CE level is level 2.

[0415] When the third CE level is the CE level determined by the terminal device based on the RSRP measurement results and the RSRP threshold value configured by the information receiving device, the third CE level is more in line with the scenario in which the terminal device is located and has higher accuracy; when the third CE level is the CE level associated with the last transmission of the first information, RSRP measurement is not required and the implementation is simple; when the third CE level is a CE level with a preset level added to the CE level associated with the last transmission of the first information, it is more reasonable and can find the appropriate CE level faster.

[0416] In a possible design of this embodiment, the first situation and the second situation can be used in combination, that is, when a first event occurs, the transmission mode of the first information is converted from using PUR transmission to using a preconfigured first type of PUSCH resource transmission, and then when the number of times the terminal device transmits the first information reaches the first number of transmissions, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission.

[0417] In a possible design of this embodiment, the first situation and the third situation can be used in combination, that is, when the number of times the terminal device transmits the first information reaches the first transmission number, the transmission mode of the first information is converted from using the preconfigured first type of PUSCH resource transmission to using the preconfigured second type of PUSCH resource transmission; when the second event occurs, the transmission mode of the first information is converted from using the preconfigured second type of PUSCH resource transmission to using EDT resources transmission.

[0418] In a possible design of this embodiment, the second situation and the third situation can be used in combination, that is, when the first event occurs, the transmission mode of the first information is converted from using PUR transmission to using pre-configured PUSCH resources for transmission, and then when the second event occurs, the transmission mode of the first information is converted from using pre-configured PUSCH resources for transmission to using EDT resources for transmission.
