[0054] For the convenience of understanding, some contents related to the embodiments of the present application are explained as follows:

[0055] 1. Ultra-low power communication technology

[0056] Backscatter communication is the most representative technology of ultra-low power communication. In principle, the backscatter communication device adjusts its internal impedance to control the reflection coefficient of the circuit, thereby changing the amplitude, frequency, phase, etc. of the radio frequency signal from other devices or the environment, to achieve signal modulation. As shown in FIG. 2, the typical hardware modules of backscatter communication include: an antenna unit, an energy harvesting module or a power supply module, a microcontroller, a signal receiving module, a channel coding and modulation module, a memory or a sensing module, etc. Among them, the signal receiving module is responsible for receiving the downlink signal sent by the network side device or the card reader to the backscatter device, and its architecture and technology can reuse the low-power wake-up receiver technology in the related technology; Since backscatter communication does not generate radio frequency signals by itself, its energy consumption is extremely low, usually between tens of microwatts and hundreds of microwatts, and it can collect environmental energy such as radio frequency signals, light energy, and thermal energy to supply signal modulation, demodulation, and reflection, without the need for its own energy source such as a battery; It can also be supplied by a small power module such as a button battery, thereby reducing the strength requirement of the power supply signal. In addition to the above typical constituent modules, the backscatter communication device can integrate a low-power amplifier module to improve the receiving sensitivity and backscatter signal power.

[0057] 2. Non-Internet of Things devices integrated with ultra-low power communication modules

[0058] The ultra-low power consumption communication module is generally applied to a terminal with high requirements on power consumption, complexity and endurance, such as an Internet of Things terminal. An extended application scenario is to apply the ultra-low power consumption communication module to a non-Internet of Things device such as a mobile phone, including a terminal and a network side device, so that the device has a main communication module and an ultra-low power consumption communication module at the same time. The main communication module has relatively high speed and spectrum efficiency, but also has relatively high power consumption, which will reduce the endurance of the device if it is turned on for a long time, and is suitable for transmitting a large amount of data in a short time. The ultra-low power consumption communication module is the opposite, which has relatively low speed and spectrum efficiency, but has very low power consumption, and is suitable for transmitting a small amount of data for a long time or for monitoring control plane signaling to avoid or reduce the additional delay caused by discontinuous reception (DRX). FIG. 3 shows a schematic diagram of information interaction between a terminal and a network side device with a main communication module and an ultra-low power consumption communication module. The two devices interact information through the ultra-low power consumption communication module, and then interact information with the main communication module in the device, such as waking up the main communication module for further operation by the ultra-low power consumption communication module.

[0059] wherein,

[0060] Main communication module: a module supporting traditional communication methods (such as 4G, 5G, etc.), for example, a module supporting OFDM communication (including uplink and / or downlink);

[0061] Ultra-low power consumption communication module: the ultra-low power consumption communication module supports transmitting signals in a backscatter manner (such as Ambient IoT Device A or Device B) or in a low-power self-generated carrier manner (such as Ambient IoT Device C) and / or supports a low-power receiving module (such as a low-power wake-up receiver); optionally, the ultra-low power consumption communication module can also support energy harvesting (collecting energy from light, solar energy, wireless signals, etc.); for the backscatter signal transmission manner, the excitation source signal can be generated by the terminal itself or other devices with the ultra-low power consumption communication module.

[0062] It should be noted that the power consumption of the ultra-low power consumption communication module is significantly lower than that of the main communication module, for example, the power consumption of the ultra-low power consumption communication module is generally tens of microwatts to hundreds of microwatts, while the power consumption of the main communication module is generally tens of milliwatts to thousands of milliwatts; the cost of the ultra-low power consumption communication module is also significantly lower than that of the main communication module.

[0063] 3. Architecture design of two communication modules sharing a physical layer (PHY)

[0064] When the two PHY modules, the main communication module and the ultra-low power communication module, are integrated in the same device at the same time, they can share the same components to save hardware costs. Generally, a wireless communication module is composed of important parts such as an antenna, a baseband, and a radio frequency front end. The main components of the radio frequency front end include a radio frequency switch (Switch), a radio frequency low noise amplifier (LNA), a radio frequency power amplifier (PA), a duplexer (DUX), and a filter (Filter). Among them, for the transmission link, the amplifier is the PA, and the filter is the transmission (Tx) filter; for the reception link, the amplifier is the LNA, and the filter is the reception (Rx) filter. There are usually multiple filters corresponding to different operating frequency bands, and the selection of the filter needs to be completed through the radio frequency switch. The duplexer is a device used to simultaneously implement the functions of transmission and reception on the same antenna to avoid / reduce the reception link from receiving its own transmitted signals. Figure 4 shows a typical architecture diagram of a wireless communication module. It should be noted that this architecture diagram is one of the possible implementations and is not unique. For example, the positions of the LNA / PA can be in different orders, the radio frequency switch and the filter can be integrated, and so on.

[0065] From a coarse-grained perspective, hardware sharing can be roughly divided into 8 cases, corresponding to whether the antenna, baseband, and radio frequency front end are shared, such as Figure 5a, where the antenna and the radio frequency front end are shared, but the baseband is independent; Figure 5b, where all three are independent; and Figure 5c, where the antenna and the radio frequency front end are independent, but the baseband is shared. For Figure 5a, a radio frequency switch is introduced at the radio frequency front end to switch to different basebands in time-division multiplexing (TDM).

[0066] Different sharing methods have different characteristics, such as:

[0067] Independent radio frequency front ends can provide independent signal transmission / reception channels for different modules, reducing mutual interference;

[0068] Independent basebands can separate the signal processing of the two modules, and the baseband of the MR can be completely turned off when the MR is not working, maximizing the reduction of power consumption;

[0069] When all hardware of the two modules is not shared, this can minimize the interference between the two modules and improve the degree of freedom of scheduling, but the cost is the highest

[0070] When all hardware of the two modules are shared, it is equivalent to making the MR process two-way signals of the MR and the ultra-low power consumption module at the same time. When the ultra-low power consumption module is not enabled or has weak performance, the MR can take over the processing of the ultra-low power consumption module, without switching to the MR at the network side, thereby reducing switching overhead

[0071] When the two modules share the radio frequency front end, whether the two modules share some components of the radio frequency front end can be further subdivided. The components of the radio frequency front end at least include a radio frequency switch, a PA, an LNA, a filter, and a duplexer, which can all be shared or not shared. FIGS. 6a-6c show several possible architectures.

[0072] In FIG. 6a, for the receiving link, all components are shared, and the received signal enters the baseband of the MR and the ultra-low power consumption module at the same time; for the transmitting link, all components are also shared, and the signals generated by the baseband of the MR and the ultra-low power consumption module are added and then transmitted through the same transmitting link. Since the two-way signals can be different in frequency bands, the baseband of the two modules at least needs to be able to process signals existing in two frequency bands.

[0073] In FIG. 6b, for the receiving link, the LNA is shared and placed before two radio frequency switches, uniformly amplifying the signal, and then passing through two independent radio frequency switches and filters to obtain two-way signals, which enter the baseband of the MR and the ultra-low power consumption module, respectively; for the transmitting link, all components are shared, and switched to the MR or the ultra-low power consumption module through a radio frequency switch. Such a design can minimize the overhead of the baseband of the MR and the ultra-low power consumption module, because they only need to process their own signals, and mutual interference is less. However, since the transmitting link is time-division, there is a certain scheduling overhead or complexity.

[0074] In FIG. 6c, the receiving link is consistent with FIG. 6a; the transmitting link uses independent radio frequency switches, PAs, and filters, and the two-way signals are independently generated, added, and then transmitted through the antenna. This design requires the baseband of the MR and the ultra-low power consumption module to be able to receive two-way signals (such as two-way signals different in frequency bands), and only needs to generate its own one-way signal, which has a lower requirement on the processing capacity of the baseband than FIG. 6a, but is higher than FIG. 6b.

[0075] 4. Random access procedure

[0076] In the related art, the random access procedure can be a contention-based random access procedure or a non-contention-based random access procedure. The random access procedure can be a four-step random access procedure (also called Type-1 random access procedure) or a two-step random access procedure (also called Type-2 random access procedure).

[0077] In a competitive 4-step random access (RACH) process, the user equipment (UE, i.e. terminal) first sends Msg1 to the network, containing a preamble; after the network detects the preamble, it will send Msg2 / Random Access Response (RAR) message, containing the number of the preamble detected by the network, and the uplink radio resource allocated to the UE to send msg3; after the UE receives Msg2, it confirms that at least one of the preamble numbers carried in Msg2 is consistent with the preamble number it sent itself, and then sends msg3 containing contention resolution information according to the resource indicated by the RAR; after the network receives msg3, it will send msg4 containing contention resolution information; after the UE receives msg4, it confirms that the resolution information is consistent with the information it sent in msg3, i.e. the 4-step random access is completed.

[0078] The network includes UL grant information in the RAR to indicate Msg3 physical uplink shared channel (PUSCH) scheduling information, and includes random access preamble identifier (RACH preamble ID, RAPID), temporary cell radio network temporary identifier (TC-RNTI), timing advance (TA) and other information. If the network does not receive Msg3 PUSCH, it can schedule the retransmission of Msg3 PUSCH in the physical downlink control channel (PDCCH) scrambled by TC-RNTI.

[0079] For the contention-based random access procedure, different UEs randomly select preambles for transmission, so that different UEs can select the same preamble for transmission on the same time-frequency radio resource (such as a random access occasion (RO) resource). This situation can be understood as preamble collision of UEs. In this case, different UEs will receive the same RAR, and then different UEs will perform Msg3 PUSCH transmission according to the scheduling information in the RAR UL grant. Since the related art does not support repeated transmission of Msg3 PUSCH, the network can only decode the PUSCH (containing contention resolution information) sent by one UE on one Msg3 PUSCH scheduling resource, so the network will include the contention resolution information received in Msg3 in Msg4. If the contention resolution information in Msg4 received by the UE matches the contention resolution information sent by the UE in Msg3 PUSCH, the UE considers that the contention resolution is successful. If they do not match, it is considered that the contention resolution is unsuccessful.

[0080] If the contention resolution is unsuccessful, the UE reselects the RACH transmission resource and performs PRACH transmission to perform the next random access attempt.

[0081] In NR Rel-16, a two-step (2-step) RACH is introduced for the two-step random access procedure. The first step is that the UE sends MsgA to the network side. After the network side receives MsgA, the UE sends MsgB to the UE. If the UE does not receive MsgB within a certain time, the UE will add one to the counter that counts the number of times of sending MsgA and resend MsgA. If the counter that counts the number of times of sending MsgA reaches a certain threshold, the UE will switch from the 2-step random access procedure to the four-step (4-step) random access procedure. MsgA includes a MsgA preamble part and a MsgA PUSCH part. The preamble part is sent on the RO for 2-step RACH, and the PUSCH part is sent on the MsgA PUSCH resource associated with the RO for sending MsgA preamble. The MsgA PUSCH resource is a set of PUSCH resources configured relative to each PRACH slot, including time-frequency resources and DMRS resources.

[0082] The transmission method, device and related equipment provided by the embodiments of the present application will be described in detail in combination with the accompanying drawings and some embodiments and application scenarios.

[0083] Referring to FIG. 7, FIG. 7 is a flowchart of a transmission method provided by an embodiment of the present application. As shown in FIG. 7, the transmission method comprises the following steps:

[0084] Step 101, a terminal determines a target communication mode for transmitting a target signal or a target channel from multiple communication modes.

[0085] Step 102, the terminal transmits the target signal or the target channel based on the target communication mode.

[0086] The multiple communication modes can refer to communication modes that have obvious differences in one or more of power consumption, frequency band, rate, transmission waveform, etc., can refer to different working parameters of the same communication hardware module, or can be different multiple communication modules. The multiple communication modules can at least have an independent component in the physical layer, such as a radio frequency front end, an antenna, and a baseband, and can also not exclude the case where all devices are completely independent.

[0087] Embodiments of the present application are applicable to all devices that have more than one communication module or one communication module with multiple communication modes. In addition, the multiple communication modules can correspond to multiple communication modes respectively, and therefore, in the embodiments of the present application, the communication module and the communication mode can have the same meaning, that is, in an implementation, the communication mode can be replaced by the communication module.

[0088] For example, the terminal determines a target communication mode for transmitting a target signal or a target channel from multiple communication modes, and the terminal transmits the target signal or the target channel based on the target communication mode, which can mean that the terminal determines a target communication module for transmitting a target signal or a target channel from multiple communication modules, and the terminal transmits the target signal or the target channel based on the target communication module. The multiple communication modules can include a first module (such as a main communication module) and a second module (such as an ultra-low power consumption communication module).

[0089] The target signal or the target channel can refer to a signal or a channel before the terminal enters a connected state, or the target signal or the target channel can refer to a signal or a channel before completing a random access process and entering a connected state, or the target signal or the target channel can refer to a signal or a channel in a random access process.

[0090] In an implementation, the target signal or the target channel can include all possible uplink signals transmitted by the terminal before successfully accessing the network and after successfully receiving a downlink signal transmitted by a network side device for the first time, or all possible uplink signals transmitted after successfully receiving a downlink signal transmitted by a network side device for the first time in a random access process in other scenarios.

[0091] In an embodiment, the target signal or target channel can include: all possible uplink signals sent by the terminal before successfully accessing the network, and after receiving (not necessarily successfully receiving) the downlink signal sent by the network side device requiring the terminal to feed back ACK / NACK, or all possible uplink signals sent in the random access process in other scenarios after receiving the downlink signal sent by the network side device requiring the terminal to feed back ACK / NACK, or PUCCH sent on the common PUCCH resource.

[0092] In an embodiment, the target signal or target channel can include: all possible uplink reference signals sent by the terminal before being in the connected state or successfully accessing the network.

[0093] In an embodiment, the terminal can determine the target communication mode for sending the target signal or target channel from the plurality of communication modes based on the first configuration information. The first configuration information can be determined based on at least one of: a protocol agreed configuration, a network side device configuration, terminal related information, a predefined or preconfigured target rule, a reason for triggering random access, and request information sent to the network side device; wherein the target rule is used to map the terminal related information to the target communication mode or the first configuration information.

[0094] In an embodiment, the terminal can determine the target communication mode for sending the target signal or target channel from the plurality of communication modes based on at least one of: a protocol agreed configuration, a network side device configuration, terminal related information, a predefined or preconfigured target rule, a reason for triggering random access, and request information sent to the network side device.

[0095] In an embodiment, the terminal can select one communication mode from the plurality of communication modes for sending the target signal or target channel, and the sending can be one time or multiple times (the multiple times correspond to repeated transmission or retransmission).

[0096] In an embodiment, the terminal can select at least two communication modes from the plurality of communication modes for sending the target signal or target channel.

[0097] Future 6G terminals may integrate more than one communication mode or communication module, such as simultaneously integrating an ultra-low power communication module on the basis of a traditional main communication module. The main communication module has relatively high rate, spectrum efficiency, but also relatively high power consumption, and if it is turned on for a long time, the endurance of the device will be reduced, and it is suitable for transmitting a large amount of data in a short time. The ultra-low power communication module is the opposite, and its rate and spectrum efficiency may be relatively low, but its power consumption is very low, and it is suitable for transmitting a small amount of data for a long time or for monitoring control plane signaling to avoid or reduce additional latency caused by DRX. How to enable a terminal with multiple communication modes or modules to efficiently and reliably access the network is still not designed, especially using multiple communication modes to cooperatively transmit initial access related channels or signals to maximize energy saving gains while ensuring performance.

[0098] Embodiments of the present application provide a method for enabling a terminal device with multiple communication modes to transmit uplink signals in a random access process or to enter a non-connected state. The terminal determines a target communication mode from multiple communication modes for transmitting a target signal or a target channel. The terminal transmits the target signal or the target channel based on the target communication mode. The target signal or the target channel can include Msg3, Msg4, or MsgB PUCCH in a random access process, or SRS in a non-connected state, and the like.

[0099] The transmission method described in the embodiments of the present application can complete the signal transmission method in the random access process for a terminal with at least two communication modes. It can implement the transmission of Msg3 using multiple communication modes, and / or the transmission of Msg4 or MsgB associated uplink physical control channel (PUCCH) using multiple communication modes, and / or the transmission of non-connected state uplink reference signals (such as SRS) using multiple communication modes.

[0100] In the embodiments of the present application, the terminal determines a target communication mode from multiple communication modes for transmitting a target signal or a target channel. The terminal transmits the target signal or the target channel based on the target communication mode. In this way, the terminal can select a target communication mode for transmitting a target signal or a target channel from multiple communication modes, and can improve the flexibility of the terminal in transmitting a target signal or a target channel.

[0105] In an implementation, the terminal can select at least two communication modes from a plurality of communication modes, and transmit the target signal or target channel at least once in a time domain respectively, and the target signal or target channel can be transmitted once or multiple times through each communication mode.

[0106] In this implementation, the terminal transmits the target signal or target channel in a time domain partially overlapping or completely overlapping manner using the at least two communication modes, which can improve the flexibility of the terminal in transmitting the target signal or target channel, and further, avoid the terminal from transmitting the uplink channel or signal by default using the first module, thereby reducing the power consumption of the terminal.

[0109] The first configuration information can be the transmission configuration of the target signal or target channel, for example, the first configuration information can include the transmission configuration of Msg3, or the transmission configuration of the PUCCH associated with Msg4 or MsgB, or the transmission configuration of SRS.

[0110] In this implementation, the terminal acquires first configuration information, and determines the target communication mode based on the first configuration information, so that the terminal can select the target communication mode according to the first configuration information, and the flexibility of the terminal in transmitting the target signal or target channel can be improved, and / or the terminal transmits the target signal or target channel based on the first configuration information, so that the terminal can transmit the target signal or target channel according to the first configuration information.

[0122] wherein the transmission configuration indication (TCI) indicated by the first configuration information can be used to determine quasi co-location (QCL), beam or precoding, path loss, etc. information of the target signal or target channel.

[0123] Optionally, the first configuration information is determined based on at least one of the following:

[0124] agreed configuration, network side device configuration, terminal related information, predefined or preconfigured target rule, cause of triggering random access, cause of triggering the target signal or target channel, request information sent to the network side device;

[0125] The target rule is used to map the terminal related information to the target communication mode or the first configuration information.

[0126] The agreed configuration can be understood as a pre-agreed configuration.

[0127] The protocol can refer to a communication protocol, for example, a 3rd Generation Partnership Project (3GPP) protocol.

[0128] The terminal related information can be used to represent the state of the terminal.

[0129] The request information sent to the network side device can be used to request the transmission configuration of the target signal or target channel.

[0130] In an embodiment, the network side device and the terminal can pre-agree the transmission configuration of the target signal or target channel, including the used communication mode, and the terminal and the network side device respectively transmit and receive according to the pre-agreed configuration.

[0131] In an embodiment, the cause of triggering random access can be associated with or preferentially associated with a transmission configuration of the target signal or target channel. Thus, the cause of triggering random access can determine the transmission configuration of the target signal or target channel.

[0132] In an embodiment, the cause of triggering the target signal or target channel can be associated with or preferentially associated with a transmission configuration of the target signal or target channel. Thus, the cause of triggering the target signal or target channel can determine the transmission configuration of the target signal or target channel.

[0133] In an embodiment, the terminal can send request information to the network side device to inform the network side device of the requested transmission configuration; the network side device can feed back the request information to indicate the transmission configuration of the target signal or target channel to the terminal.

[0134] In this embodiment, the terminal can determine the first configuration information according to at least one of the protocol-agreed configuration, the network-side device configuration, the terminal-related information, the pre-defined or pre-configured target rule, the reason for triggering random access, and the request information sent to the network-side device, and then determine the target communication mode for sending the target signal or the target channel from the multiple communication modes through the first configuration information, so as to improve the flexibility of the terminal in sending the target signal or the target channel. Further, the transmission configuration and the transmission mode of the target signal or the target channel are determined through the rule or the configuration, so as to avoid the inconsistency in understanding between the network-side device and the terminal, and further improve the transmission success rate.

[0135] Optionally, the terminal-related information includes at least one of the following:

[0136] The transmission configuration of the uplink signal or the uplink channel sent by the terminal before sending the target signal or the target channel in the random access process;

[0137] Whether the uplink signal or the uplink channel sent by the terminal before sending the target signal or the target channel in the random access process is retransmitted or repeatedly transmitted;

[0138] The number of retransmissions or repeated transmissions of the uplink signal or the uplink channel sent by the terminal before sending the target signal or the target channel in the random access process;

[0139] The reception configuration of the downlink signal or the downlink channel received by the terminal before sending the target signal or the target channel in the random access process;

[0140] Whether the downlink signal or the downlink channel received by the terminal before sending the target signal or the target channel in the random access process is retransmitted or repeatedly transmitted;

[0141] The number of retransmissions or repeated transmissions of the downlink signal or the downlink channel received by the terminal before sending the target signal or the target channel in the random access process;

[0142] The transmission confirmation information of the downlink signal or the downlink channel received by the terminal before sending the target signal or the target channel in the random access process;

[0143] The transmission confirmation information of the uplink signal or the uplink channel sent by the terminal before sending the target signal or the target channel in the random access process;

[0144] The measurement quantity of the downlink reference signal of the terminal;

[0145] The type of the random access process, and the target signal or the target channel is a signal or a channel in the random access process;

[0146] Power-related information of the random access procedure;

[0147] Whether the terminal supports multiple communication modes;

[0148] Characteristics, Key Performance Indicators (KPIs), or service requirements that the terminal needs to use;

[0149] Working conditions or KPIs of multiple communication modes of the terminal;

[0150] Whether multiple communication modes of the terminal support simultaneous use;

[0151] Combinations of communication modes that the terminal supports for simultaneous use;

[0152] Location of a cell where the terminal is located;

[0153] Downlink reference signal or downlink reference signal group selected by the terminal;

[0154] Random access corresponding to at least one of a transmission and reception point (TRP), a frequency, a frequency band, a sub-band, a carrier, and a synchronization raster selected by the terminal.

[0155] The transmission confirmation information can include ACK or NACK information.

[0156] The measurement quantity of the downlink reference signal can include, but is not limited to, a measurement quantity of a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS). The measurement quantity of the downlink reference signal can reflect the condition of a wireless channel, thereby enabling selection of the most suitable communication mode and transmission configuration in subsequent transmission.

[0157] In addition, the type of the random access procedure can include two-step or four-step random access. For example, when a network simultaneously configures 2-step RACH and 4-step RACH resources, and a terminal initially selects 4-step RACH, transmission of a target signal or a target channel can use low-power mode transmission.

[0158] For another example, whether to switch from 2-step random access to 4-step random access, for example, when high-power mode transmission is used for transmission of a target signal or a target channel in a fallback procedure, the fallback can mean that the channel condition is poor, and a more reliable transmission mode needs to be selected for subsequent transmission.

[0159] The working conditions or KPIs of the multiple communication modes of the terminal can include at least one of a waveform, a modulation mode, a coding mode, a frequency band, power consumption or power level, reliability, latency, and the like supported by the terminal.

[0160] For example, when the terminal selects repeated transmission for the transmitted uplink signal or uplink channel before transmitting the target signal or target channel in the random access process, it means that the channel condition can be relatively poor or the reliability requirement is relatively high, and the subsequent transmission can select a transmission mode capable of providing higher reliability, such as high-power consumption mode.

[0161] For example, when the terminal selects repeated transmission for the transmitted uplink signal or uplink channel before transmitting the target signal or target channel in the random access process, and the number of repeated transmissions exceeds a certain threshold, it means that the channel condition can be relatively poor or the reliability requirement is relatively high, and the subsequent transmission can select a transmission mode capable of providing higher reliability, such as high-power consumption mode.

[0162] For example, when the terminal selects repeated transmission for the received downlink signal or downlink channel before transmitting the target signal or target channel in the random access process, it means that the channel condition can be relatively poor or the reliability requirement is relatively high, and the subsequent transmission can select a transmission mode capable of providing higher reliability, such as high-power consumption mode.

[0163] For example, when the terminal selects repeated transmission for the received downlink signal or downlink channel before transmitting the target signal or target channel in the random access process, and the number of repeated transmissions exceeds a certain threshold, it means that the channel condition can be relatively poor or the reliability requirement is relatively high, and the subsequent transmission can select a transmission mode capable of providing higher reliability, such as high-power consumption mode.

[0164] For example, when the terminal is located at the cell edge, the transmission of the target signal or target channel can select high-power consumption mode.

[0165] For example, for random access corresponding to a specific reference signal group, the corresponding target signal or target channel can use high-power consumption transmission; for random access corresponding to other reference signal groups, the transmission of the corresponding target signal or target channel can use low-power consumption transmission. It should be noted that the corresponding beams and coverage conditions under different reference signal groups can be different, so that the target signal or target channel can be transmitted using different communication modes, which has higher flexibility.

[0166] For example, for a random access corresponding to at least one of a specific TRP, a frequency, a frequency band, a sub-band, a carrier or a synchronization raster, a high-power transmission is used for transmission of the corresponding target signal or target channel; for other cases, a low-power transmission is used for transmission of the corresponding target signal or target channel. It should be noted that the corresponding beam and coverage conditions may be different under different TRPs, frequencies, frequency bands, sub-bands, carriers or synchronization rasters, so that the target signal or target channel can be transmitted using different communication modes respectively, and the flexibility is higher.

[0167] In this embodiment, the terminal can determine the target communication mode for transmitting the target signal or target channel from multiple communication modes by considering the terminal-related information, so as to improve the flexibility of the terminal in transmitting the target signal or target channel; further, the terminal-related information can reflect the condition of the wireless channel of the terminal to a certain extent, so as to facilitate the terminal to select a suitable communication mode to transmit the target signal or target channel, and avoid the terminal from transmitting the uplink channel or signal by default using the first mode, thereby reducing the power consumption of the terminal.

[0168] Optionally, the power-related information of the random access procedure includes at least one of the following:

[0169] a power increment value for transmitting a signal in the random access procedure;

[0170] an accumulated value of the power increment value for transmitting the signal in the random access procedure;

[0171] transmission power state information of the target signal or target channel;

[0172] transmission power control state information of the target signal or target channel.

[0173] In one embodiment, when the power increment value for transmitting the signal in the random access procedure is greater than a preset threshold, a high-power mode transmission can be selected for transmission of the target signal or target channel. When the power increment value for transmitting the signal in the random access procedure is greater than the preset threshold, it means that the channel condition may be poor or the reliability requirement is high, and a high-power mode transmission can be selected for transmission of the target signal or target channel.

[0174] In one embodiment, when the accumulated value of the power increment value for transmitting the signal in the random access procedure is greater than a preset threshold, a high-power mode transmission can be selected for transmission of the target signal or target channel. When the accumulated value of the power increment value for transmitting the signal in the random access procedure is greater than the preset threshold, it means that the channel condition may be poor or the reliability requirement is high, and a high-power mode transmission can be selected for transmission of the target signal or target channel.

[0175] In one embodiment, when the transmission power state information of the target signal or the target channel indicates that the transmission power value is greater than a preset threshold, the transmission of the target signal or the target channel can select a high power consumption mode transmission.

[0176] In one embodiment, when the transmission power control state information of the target signal or the target channel indicates that the transmission power value is greater than a preset threshold, the transmission of the target signal or the target channel can select a high power consumption mode transmission.

[0177] In this embodiment, the terminal can determine the target communication mode for transmitting the target signal or the target channel from multiple communication modes considering the power-related information of the random access procedure, which can improve the flexibility of the terminal in transmitting the target signal or the target channel. Further, the power-related information of the random access procedure can reflect the condition of the wireless channel of the terminal to some extent, so that the terminal can select a suitable communication mode to transmit the target signal or the target channel, avoiding the terminal from defaulting to the first mode to transmit the uplink channel or signal, and reducing the power consumption of the terminal.

[0194] In the method, determining the communication mode for transmitting the target signal or the target channel based on whether the terminal supports multiple communication modes can include: if the terminal does not support multiple communication modes for communication, selecting a legacy mode for transmitting the target signal or the target channel, otherwise, other rules can be matched for further determination; for example, a set of available communication modes can be determined according to combinations of multiple communication modes that can be used simultaneously.

[0195] In the method, selecting the target communication mode for transmitting the target signal or the target channel from the set of available communication modes based on the characteristics, KPIs or service requirements that the terminal needs to use can include:

[0196] When the current service requirement of the terminal is a large-flow or high-reliability service, the terminal can determine to transmit the target signal or the target channel in a high-power-consumption or high-performance mode, etc.; or

[0197] When the payload size of the target receiving or transmitting physical channel meets certain conditions, such as being greater than a certain threshold, the terminal can determine to transmit the target signal or the target channel in a high-power-consumption or high-performance mode, etc.

[0198] When the target receiving or transmitting physical channel needs a specific waveform, modulation method, coding method, etc., the terminal can determine a communication mode capable of providing a corresponding service capability to transmit the target signal or target channel.

[0199] In an embodiment, the first configuration information is determined based on a transmission configuration of an uplink signal or uplink channel transmitted before the target signal or target channel in the random access procedure, which can include:

[0200] The target signal or target channel adopts the same transmission configuration as the transmission configuration (i.e., reference configuration) of the uplink signal or uplink channel; or

[0203] Based on the resource of the reference configuration, a specific rule is mapped to the target resource;

[0204] Based on the number of repetitions of the reference configuration, a specific rule is mapped to the target number of repetitions;

[0205] When the target signal or target channel has repeated transmission, the determined transmission configuration can be for all transmissions of the target signal or target channel, or single or multiple transmissions.

[0206] In an embodiment, the first configuration information is determined based on a transmission configuration of a downlink signal or downlink channel transmitted before the target signal or target channel in the random access procedure, which can include:

[0207] The target signal or target channel adopts a transmission configuration associated with the transmission configuration (i.e., reference configuration) of the downlink signal or downlink channel, such as:

[0208] Based on the communication mode of the reference configuration, a specific rule is mapped to the target communication mode;

[0209] Based on the resource of the reference configuration, a specific rule is mapped to the target resource;

[0230] The terminal receiving the fallback indication indicates that the current load is relatively high, and the transmission of the target signal or target channel can use higher power transmission, which can reduce the number of retransmissions and repeated transmissions of the target signal or target channel, and save time-frequency resource usage.

[0231] In this embodiment, the terminal can determine the target communication mode for transmitting the target signal or the target channel from the multiple communication modes according to the above rule, and the flexibility of the terminal in transmitting the target signal or the target channel can be improved.

[0233] The first configuration information is configuration information configured for the target signal or the target channel according to multiple transmissions.

[0234] In one embodiment, the first configuration information is configuration information configured for the target signal or the target channel according to single transmission, so that each transmission of the target signal or the target channel is configured individually, and multiple repetitions or retransmissions belonging to the same target signal or target channel are associated.

[0235] In one embodiment, the first configuration information is configuration information configured for the target signal or the target channel according to multiple transmissions, so that multiple repetitions or retransmissions belonging to the target signal or the target channel are jointly configured, such as considering all possible repetitions or retransmissions when configuring time domain, frequency domain or code domain resources, signal formats, target communication modes used, etc.

[0236] In this embodiment, the first configuration information is configuration information configured for the target signal or the target channel according to single transmission, and configuration information belonging to the target signal or the target channel has an association relationship, and the flexibility of single transmission configuration is greater; or, the first configuration information is configuration information configured for the target signal or the target channel according to multiple transmissions, and multiple transmissions are jointly configured, which can save signaling overhead.

[0237] Optionally, the terminal obtains the first configuration information, including:

[0238] The terminal receives the first configuration information sent by the network side device through at least one of the following:

In this way, the network side device can configure the target communication mode for the terminal to send the target signal or the target channel by considering the capability of the terminal, and the flexibility of the terminal in sending the target signal or the target channel can be improved.

[0253] Optionally, the target capability information is associated with or corresponds to at least one of the following:

[0255] In this embodiment, the terminal can report the target capability information at the granularity of at least one of the terminal, the frequency band, the frequency band combination, the terminal type, the application scenario, the TRP, the cell, the reference signal group or the reference signal, and the flexibility of reporting the target capability information is higher.

[0256] Optionally, the terminal sends the target capability information to the network side device, including:

[0257] The terminal sends the target capability information to the network side device by at least one of the following:

[0258] Physical random access channel (PRACH) signal; WUS or sounding reference signal (SRS) signal; Msg3 physical uplink shared channel (PUSCH); MsgA PUSCH; RRC signaling.

[0259] In this embodiment, the terminal sends the target capability information by at least one of the PRACH signal, the WUS or the SRS signal, the Msg3 PUSCH, the MsgA PUSCH, and the RRC signaling, so that the transmission of the target capability information can be realized by using the existing signaling.

[0260] Optionally, the target signal or the target channel includes at least one of the following:

[0261] The terminal sends an uplink signal or an uplink channel after successfully receiving a downlink signal or a downlink channel sent by the network side device for the first time before successfully accessing the network or before completing the random access process;

[0262] The terminal transmits an uplink signal or an uplink channel after receiving a downlink signal or a downlink channel transmitted by the network side device and requiring the terminal to feed back transmission confirmation information before successfully accessing the network or before completing the random access process.

[0263] The uplink reference signal transmitted by the terminal in the non-connected state, or the uplink reference signal transmitted by the terminal before successfully accessing the network.

[0264] Optionally, the target communication mode includes transmission by a first module and / or transmission by a second module, the first module and the second module being two different working modes or modules with different power consumptions.

[0265] The first module can be a main communication module or a high-power consumption mode, and the second module can be an extremely low-power consumption communication module or a low-power consumption mode.

[0266] The following is further illustrated by examples:

[0267] The Msg3 described in the following examples can refer to all possible uplink signals transmitted by the terminal before successfully accessing the network and after successfully receiving a downlink signal transmitted by the network side, or all possible uplink signals transmitted by the terminal after successfully receiving a downlink signal transmitted by the network side in a random access process in other scenarios.

[0268] The Msg4 or MsgB associated PUCCH or Msg4 or MsgB PUCCH described in the following examples can refer to all possible uplink signals transmitted by the terminal before successfully accessing the network and after receiving (not necessarily successfully receiving) a downlink signal transmitted by the network side and requiring the terminal to feed back ACK / NACK, or all possible uplink signals transmitted by the terminal after receiving a downlink signal transmitted by the network side and requiring the terminal to feed back ACK / NACK in a random access process in other scenarios, or PUCCH transmitted on a common PUCCH resource.

[0269] The SRS described in the following examples can refer to all possible uplink reference signals transmitted by the terminal in the non-connected state or before successfully accessing the network.

[0270] Example Group One: Several Ways of Transmitting Signals

[0271] Since the terminal can have multiple communication modes, signals can be transmitted in multiple ways.

[0272] In some examples (Case 1), the terminal selects one communication mode from multiple communication modes for transmission, and transmission can be one time or multiple times (multiple times correspond to repeated transmission or retransmission).

[0273] In some examples (Case 2), the terminal selects at least two communication modes from the plurality of communication modes, and transmits at least once in each mode in a time-division manner, wherein each mode can be transmitted once or multiple times.

[0274] In some examples (Case 3), the terminal selects at least two communication modes from the plurality of communication modes, and transmits at least once in each mode in a time-division manner, wherein each mode can be transmitted once or multiple times.

[0275] Case 1 and Case 2 do not require multiple modes to work simultaneously; Case 3 requires multiple modes to work simultaneously, and which modes can work simultaneously depends on the terminal's capability (such as whether the devices used in each mode are shared or independent) and the network side's configuration (such as which resources the network side supports for simultaneous reception of signals).

[0276] From the perspective of the terminal as a whole, the signals in Case 1 can be single transmission or repeated transmission, while Case 2 and Case 3 must be repeated transmission.

[0277] For Case 2 and Case 3, there is a case where, according to the configuration or agreement, the terminal's multiple communication modes need to transmit at least one signal respectively, but due to some reasons, such as having successfully received the network side's return downlink signal, or terminal power consumption or hardware limitations, etc., the signals that should be transmitted by some modes are cancelled. This example also applies to this case.

[0278] Example Group Two: Transmission of Msg3

[0279] This example mainly sets forth the determination of the transmission configuration of Msg3 including the communication mode and the transmission method of Msg3.

[0280] In some examples, the transmission configuration of Msg3 includes at least one of the following information:

[0281] Target communication mode, communication mode group or communication mode set for transmitting Msg3;

[0282] Whether to repeat or retransmit the transmission;

[0283] Resource of each transmission in single transmission or repeated or retransmitted transmission, including time domain, frequency domain or code domain resource;

[0284] Signal format of each transmission in single transmission or repeated or retransmitted transmission, such as CP format or length, SCS, TBS, DMRS configuration (such as DMRS port, DMRS pattern), MCS, (if the transmission resource includes code domain) spreading sequence or sequence set, waveform, transmission power (including initial transmission power, target transmission power, power climbing step, etc.).

[0285] The TCI-State of each transmission in a single transmission or repeated or retransmission, the TCI-State is used to determine information such as QCL, beam or precoding, path loss, etc. of Msg3.

[0286] The correspondence between each transmission and the target communication mode in a single transmission, repeated transmission, or retransmission.

[0287] As a sub-example of the above example, for the case of Msg3 repeated or retransmitted transmission (including single-mode repeated or retransmitted transmission and multi-mode repeated or retransmitted transmission), the above Msg3 transmission configuration can be configured separately for each transmission and then associated, or configured jointly.

[0288] Individual configuration followed by association: Each Msg3 transmission is configured individually, but multiple duplicate or retransmissions belonging to the same Msg3 will be associated. Individual configuration offers greater flexibility.

[0289] Joint configuration: Joint configuration refers to multiple repetitive or retransmitted transmissions of Msg3. For example, when configuring time-domain, frequency-domain, or code-domain resources, signal format, and the target communication module used, all possible repetitive or retransmitted transmissions are taken into account. Joint configuration can save signaling.

[0290] In some examples, the terminal determines the transmission configuration of Msg3 in at least one of the following ways:

[0291] Pre-agreed configuration;

[0292] Determine the transmission configuration for Msg3 based on network instructions;

[0293] The transmission configuration of Msg3 is determined based on terminal-related information and target rules;

[0294] Based on the reasons (or conditions) that trigger random access;

[0295] The terminal requests the Msg3 sending configuration.

[0296] In this way, by using rules or configurations to determine the sending configuration and transmission mode of Msg3, inconsistencies in understanding between the network side and the terminal are avoided, thus improving the transmission success rate.

[0297] As a first seed example of the above example, the network and the terminal can pre-agree on the transmission configuration of Msg3, including the communication mode used, and the terminal and the network will send and receive according to the pre-agreement configuration respectively.

[0298] As a second sub-example of the above example, the network can indicate the transmission configuration of Msg3 to the terminal in the current serving cell or neighbor cell through at least one of the following ways:

[0299] broadcast information such as MIB, SIB or paging;

[0300] information such as RRC, MAC CE or DCI;

[0301] Msg2 (such as random access response (RAR) or PDSCH scheduled by DCI scrambled by random access RNTI (RA-RNTI));

[0302] fallback RAR information;

[0303] downlink WUS signal;

[0304] or other downlink signals received before transmitting Msg3 or scheduling Msg3.

[0305] As a third sub-example of the above example, the transmission configuration of Msg3 is determined based on terminal-related information and / or predefined or preconfigured target rules.

[0306] wherein the terminal-related information includes at least one of the following:

[0307] (1) transmission configuration of the uplink signal before Msg3 in the random access procedure;

[0308] (2) whether the uplink signal before Msg3 in the random access procedure is retransmitted or repeatedly transmitted;

[0309] For example, when the Msg1 transmission selects repeated transmission, the Msg3 transmission selects high-power mode transmission. In this way, when repeated transmission or retransmission is selected, it means that the channel condition may be poor or the reliability requirement is high, and the subsequent transmission can select a transmission mode that can provide higher reliability, such as high-power mode.

[0310] (3) number of retransmissions or repeated transmissions of the uplink signal before Msg3 in the random access procedure;

[0311] For example, when the Msg1 transmission selects repeated transmission and the number of repeated transmissions exceeds a certain threshold, the Msg3 transmission selects high-power mode transmission;

[0312] (4) reception configuration of the downlink signal before Msg3 in the random access procedure;

[0313] (5) Whether the downlink signal before Msg3 in the random access procedure is retransmitted or repeatedly transmitted;

[0314] For example, when the Msg2 transmission selects repeated transmission, the Msg3 transmission selects high-power mode transmission;

[0315] (6) The number of retransmissions or repeated transmissions of the downlink signal before Msg3 in the random access procedure;

[0316] For example, when the Msg2 transmission selects repeated transmission and the number of repeated transmissions exceeds a certain threshold, the Msg3 transmission selects high-power mode transmission;

[0317] (7) ACK / NACK information of the downlink signal before Msg3 in the random access procedure;

[0318] (8) ACK / NACK information of the uplink signal before Msg3 in the random access procedure;

[0319] (9) Measurement quantity of the downlink reference signal, including but not limited to SSB, CSI-RS;

[0320] The measurement quantity of the downlink reference signal can reflect the condition of the wireless channel, so that the most suitable communication mode and transmission configuration can be selected in subsequent transmission;

[0321] (10) Type of the random access procedure;

[0322] For example, 2 / 4-step random access, such as when the network configures both 2-step RACH and 4-step RACH resources, and the UE initially selects 4-step RACH, the Msg3 transmission uses low-power mode transmission;

[0323] For example, whether to switch from 2-step random access to 4-step random access, such as using high-power mode transmission for Msg3 transmission in the fallback process, fallback may mean that the channel condition is poor, and a more reliable transmission mode needs to be selected for subsequent transmission.

[0324] (11) Power-related information of the random access procedure (or expressed as the state of the random access procedure);

[0325] The power-related information of the random access procedure includes at least one of the following:

[0326] Power increment (or expressed as power climb value), such as when the Msg1 power climb reaches a certain threshold, the Msg3 transmission uses high-power mode;

[0327] The accumulated value of power increment (or expressed as power climb accumulation), such as when the Msg1 power climb accumulation reaches a certain threshold, the msg3 transmission uses a high power consumption mode;

[0328] The Msg3 transmission power state information (or expressed as transmission power value state), such as when the Msg3 calculated transmission power value reaches or exceeds the low power consumption maximum value, the Msg3 transmission uses a high power consumption mode transmission;

[0329] The Msg3 transmission power control state information (or expressed as transmission power control value state), such as when the Msg3 transmission power control command indicates the value reaches the maximum value or a predefined value, the Msg3 transmission uses a high power consumption mode transmission.

[0330] (12) UE feature about terminal transmission mode, whether to support multiple communication modes;

[0331] The UE feature can be combined with other UE features to form a feature combination.

[0332] (13) Features, KPIs, service requirements, etc. currently required by the terminal;

[0333] Such as Ultra-Reliable and Low Latency Communications (URLLC), Non Terrestrial Network (NTN), frequency band, early PRACH (before using the second communication mode, the terminal sends PRACH to the network side using the first communication mode, and then uses the second communication module to communicate with the network side) and the like.

[0334] (14) Working conditions / KPIs of multiple communication modes of the terminal;

[0335] Such as at least one of the supported waveform, modulation method, coding method, frequency band, power consumption / charge, reliability, latency, etc.

[0336] (15) Whether the multiple communication modes of the terminal support simultaneous use, and the combination of simultaneous use;

[0337] Such as when mode 1 is working, mode 2 and mode 3 cannot work; or when mode 1 does not work, mode 2 and mode 3 can work simultaneously.

[0338] (16) The location of the cell where the terminal is located;

[0339] Such as for cell edge users, a high power consumption communication mode can be used.

[0340] (17) Random access corresponding to at least one of the following selected by the terminal: downlink reference signal (such as SSB signal used for selecting RACH resource) or reference signal group;

[0341] For example, for random access corresponding to a certain reference signal group, the corresponding Msg3 uses high-power transmission; for random access corresponding to other reference signal groups, the corresponding Msg3 transmission uses low-power transmission.

[0342] Here, the corresponding beam and coverage conditions under different reference signal groups may be different, so different modes of Msg3 transmission should be used respectively.

[0343] (18) Random access corresponding to at least one of the following selected by the terminal: TRP, frequency, frequency band, sub-band, carrier or synchronization raster;

[0344] For example, for random access corresponding to at least one of the following selected by the terminal: TRP, frequency, frequency band, sub-band, carrier or synchronization raster, the corresponding Msg3 uses high-power transmission; for random access corresponding to other situations, the corresponding Msg3 transmission uses low-power transmission.

[0345] Here, the corresponding beam and coverage conditions under different TRPs, frequencies, frequency bands, sub-bands, carriers or synchronization rasters may be different, so different modes of Msg3 transmission should be used respectively.

[0346] The pre-defined or pre-configured target rules include one or more of the following:

[0347] (1) If the terminal does not support multiple communication modes for communication, select the legacy mode for Msg3 transmission, otherwise continue to match other rules for next step judgment;

[0348] (2) Determine the available set of communication modes according to the combination that can be used at the same time;

[0349] (3) Select a set from the available set of communication modes according to the feature, KPI or service requirement currently required by the terminal, such as:

[0350] When the current service requirement of the terminal is large flow or high reliability service, the terminal can determine to send Msg3 and the like in high-power or high-performance mode;

[0351] When the Payload size of the target received or transmitted physical channel meets certain conditions, such as greater than a certain threshold, the terminal can also determine to send Msg3 and the like in high-power or high-performance mode;

[0352] When the target receiving or transmitting physical channel needs specific waveform, modulation mode, coding mode, etc., the communication mode capable of providing corresponding service capability can be determined.

[0353] (4) Determine the transmission configuration of Msg3 based on the transmission configuration (reference configuration) of the uplink or downlink signal before Msg3 in the random access procedure, such as:

[0354] (a) Msg3 adopts the same transmission configuration as the reference configuration of the uplink signal;

[0355] (b) Msg3 adopts the transmission configuration associated with the reference configuration of the uplink signal, such as:

[0356] Based on the communication mode of the reference configuration, map to the target communication mode according to specific rules;

[0357] Based on the resource of the reference configuration, map to the target resource according to specific rules;

[0358] Based on the number of repetitions of the reference configuration, map to the target number of repetitions according to specific rules;

[0359] When Msg3 has repeated transmission, the determined transmission configuration can be for all transmissions of Msg3, or single or multiple transmissions.

[0360] (c) Msg3 adopts the transmission configuration associated with the reference configuration of the downlink signal, such as:

[0361] Based on the communication mode of the reference configuration, map to the target communication mode according to specific rules;

[0362] Based on the resource of the reference configuration, map to the target resource according to specific rules;

[0363] Based on the number of repetitions of the reference configuration, map to the target number of repetitions according to specific rules;

[0364] When Msg3 has repeated transmission, the determined transmission configuration can be for all transmissions of Msg3, or single or multiple transmissions.

[0365] (5) Determine the transmission configuration of Msg3 based on the retransmission or repetition number of the uplink or downlink signal before Msg3 in the random access procedure, such as,

[0366] When the retransmission number exceeds or does not exceed a specific threshold, the configured or agreed transmission configuration is adopted, including the communication mode.

[0367] (6) Determine the transmission configuration of Msg3 based on the ACK or NACK information of the uplink or downlink signal before Msg3 in the random access procedure, such as,

[0368] When the number of ACK or NACK exceeds or does not exceed a certain threshold, the configured or agreed transmission configuration is adopted, including the communication mode.

[0369] (7) Determine the transmission configuration of Msg3 based on the MCS or code rate information of the uplink or downlink signal before Msg3 in the random access process, such as,

[0370] When the MCS or code rate is within a specified range, the configured or agreed transmission configuration is adopted, including the communication mode.

[0371] (8) Determine the transmission configuration of Msg3 based on the scheduling information before Msg3 in the random access process, such as,

[0372] When the aggregation level (AL) of the scheduling DCI is within a specified range or exceeds a certain threshold, the configured or agreed transmission configuration is adopted, including the communication mode;

[0373] When the repetition number of the scheduling DCI is within a specified range or exceeds a certain threshold, the configured or agreed transmission configuration is adopted, including the communication mode.

[0374] (9) Determine the transmission configuration of Msg3 based on the measurement quantity of the downlink reference signal, such as,

[0375] When the measurement quantity of the downlink reference signal exceeds or does not exceed a certain threshold, the configured or agreed transmission configuration is adopted, including the communication mode;

[0376] For example, when the RSRP of the measured associated SSB exceeds or is not less than a certain threshold, the terminal transmits Msg3 using a low-power mode to save energy.

[0377] (10) Determine the transmission configuration of Msg3 based on the type or state of the random access process, such as,

[0378] 2-step random access and 4-step random access respectively adopt the configured or agreed transmission configuration;

[0379] Or, if switching from 2-step random access to 4-step random access, the configured or agreed transmission configuration is adopted;

[0380] Or, when the power ramping value or power ramping accumulation exceeds or does not exceed a certain threshold, the configured or agreed transmission configuration is adopted, including the communication mode.

[0381] (11) Based on whether the random access process receives a Backoff Indicator (backoff indicator);

[0382] For example, when the terminal receives a back-off indication, it indicates that the current load is relatively high, and msg3 transmission can use higher power transmission to reduce msg3 retransmission and repeated transmission times, and save time-frequency resource usage.

[0383] As a fourth sub-example of the above example, based on the condition of terminal triggering random access, the terminal determines a Msg3 transmission configuration, such as:

[0384] The reasons for triggering random access include: PDCCH (command) Order, Paging, obtaining SIB, requesting to send resources when uplink resources are insufficient, Radio Link Failure (RLF) or BLF, etc.

[0385] The above reasons can be associated with or preferentially associated with a Msg3 transmission configuration;

[0386] The above reasons can be combined with the rules related to service demand in the third sub-example, such as when receiving Paging and the service is a small data MT service, the terminal can use a low-power mode to complete the transmission of Msg3.

[0387] As a fifth sub-example of the above example, based on the terminal's request to the network side, a Msg3 transmission configuration is determined, such as:

[0388] Through the binding of a specific preamble and a specific transmission configuration in Msg1 or MsgA, the network side is informed; or through the specific sequence or sequence generation method of SRS and the binding of a specific transmission configuration, the network side is informed; or before the random access process, the terminal informs the network side through other ways (such as in the device registration process).

[0389] Optionally, the network side can carry a confirmation of the terminal's request in Msg2 or MsgB, or indicate the use of a specific transmission configuration.

[0390] Example Group Three: Msg4 or Msg B Associated PUCCH Transmission

[0391] This example group mainly describes the determination of the transmission configuration of Msg4 or Msg B associated PUCCH (hereinafter referred to as PUCCH), and its transmission method.

[0392] In some examples, the transmission configuration of PUCCH includes at least one of the following information:

[0393] The target communication mode, communication mode group, or communication mode set for transmitting PUCCH;

[0394] Whether to repeat or retransmit the transmission;

[0395] resources of each transmission in the single transmission or the repetition or retransmission transmission, including time domain, frequency domain or code domain resources;

[0396] signal format of each transmission in the single transmission or the repetition or retransmission transmission, such as CP format or length, SCS, TBS, DMRS configuration (such as DMRS port, DMRS pattern, number of DMRS symbols), MCS, (if the transmission resources include code domain) spreading sequence or sequence set, waveform, transmission power (including initial transmission power, target transmission power, power climbing step, etc.), PUCCH format, etc.;

[0397] TCI state of each transmission in the single transmission or the repetition or retransmission transmission, the TCI state being used to determine QCL, beam or precoding, path loss, etc. information of the PUCCH;

[0398] correspondence between each transmission in the single transmission or the repetition or retransmission transmission and the target communication mode.

[0399] As a sub-example of the above example, for the case of PUCCH repetition or retransmission transmission (including single-mode repetition or retransmission transmission and multi-mode repetition or retransmission transmission), the above transmission configuration of the PUCCH can be configured separately and then associated according to the single transmission, or jointly configured.

[0400] separate configuration and association: each PUCCH transmission is configured separately, but multiple repetitions or retransmissions belonging to the same Msg3 are associated;

[0401] joint configuration: multiple repetitions or retransmissions of the PUCCH are jointly configured, such as considering all possible repetitions or retransmissions when configuring time domain, frequency domain or code domain resources, signal format, target communication mode used, etc.

[0402] In some examples, the terminal determines the transmission configuration of the PUCCH by at least one of the following ways:

[0403] pre-agreed configuration;

[0404] determining the transmission configuration of the PUCCH according to network indication;

[0405] determining the transmission configuration of the PUCCH according to terminal related information and target rules;

[0406] based on the reason (or condition) for triggering random access.

[0407] As a first sub-example of the above example, the network and the terminal can pre-agree the transmission configuration of the PUCCH, including the communication mode used, and the terminal and the network respectively transmit and receive according to the pre-agreed configuration.

[0408] As a second sub-example of the above example, the network can indicate the transmission configuration of PUCCH to the terminal in the current serving cell or neighbor cell through at least one of the following ways:

[0409] broadcast information such as MIB, SIB or paging;

[0410] information such as RRC, MAC CE or DCI;

[0411] Msg2, Msg4 or MsgB;

[0412] downlink WUS signal;

[0413] other downlink signals received before the transmission of PUCCH.

[0414] As a third sub-example of the above example, the transmission configuration of Msg3 is determined based on terminal-related information and / or predefined or preconfigured target rules.

[0415] wherein the terminal-related information includes at least one of the following:

[0416] (1) the transmission configuration of the uplink signal before PUCCH in the random access procedure;

[0417] (2) whether the uplink signal before PUCCH in the random access procedure is retransmitted or repeated;

[0418] For example, when the Msg1 transmission selects repeated transmission, the PUCCH transmission selects high-power mode transmission.

[0419] (3) the number of retransmissions of the uplink signal before PUCCH in the random access procedure;

[0420] For example, when the Msg1 transmission selects repeated transmission and the number of repeated transmissions exceeds a certain threshold, the PUCCH transmission selects high-power mode transmission.

[0421] (4) the reception configuration of Msg4 or MsgB and / or previous downlink signal in the random access procedure;

[0422] (5) whether the Msg4 or MsgB and / or previous downlink signal in the random access procedure is retransmitted or repeated;

[0423] For example, when the Msg4 or MsgB transmission selects repeated transmission, the PUCCH transmission selects high-power mode transmission.

[0424] (6) the number of retransmissions of Msg4 or MsgB and / or previous downlink signal in the random access procedure;

[0425] For example, when Msg4 or MsgB transmission selects repetition transmission and the number of repetition transmission exceeds a certain threshold, PUCCH transmission selects high power mode transmission.

[0426] (7) ACK or NACK information of Msg4 or MsgB and / or previous downlink signal in random access procedure;

[0427] (8) ACK or NACK information of PUCCH previous uplink signal in random access procedure;

[0428] (9) Measurement quantity of downlink reference signal, including but not limited to SSB, CSI-RS;

[0429] (10) Type of random access procedure;

[0430] For example, when the network configures 2-step RACH and 4-step RACH resources at the same time, and the UE initially selects 4-step RACH, PUCCH transmission uses low power mode transmission;

[0431] For example, when the network configures 2-step RACH and 4-step RACH resources at the same time, and the UE initially selects 4-step RACH, PUCCH transmission uses low power mode transmission;

[0432] (11) Power related information (or expressed as the state of random access procedure) of random access procedure, including at least one of the following:

[0433] Power increment (or expressed as power climb value), for example, when Msg1 power climb reaches a certain threshold, PUCCH transmission uses high power mode;

[0434] Cumulative value of power increment (or expressed as power climb cumulative quantity), for example, when Msg1 power climb cumulative quantity reaches a certain threshold, PUCCH transmission uses high power mode;

[0435] PUCCH transmission power state information (or expressed as transmission power value state), for example, when PUCCH calculated transmission power value reaches or exceeds the maximum value of low power, PUCCH transmission uses high power mode transmission;

[0436] PUCCH transmission power control state information (or expressed as transmission power control value state), for example, when PUCCH transmission power control command value reaches the maximum value or a predefined value, PUCCH transmission uses high power mode transmission.

[0437] (12) UE feature on terminal transmission mode, whether to support multiple communication modes;

[0438] The UE feature can be combined with other UE features to form a feature combination.

[0439] (13) Features, KPIs, service requirements, etc. currently required by the terminal;

[0440] For example, URLLC, NTN, frequency band, early PRACH (the terminal sends PRACH to the network side using the first communication mode before using the second communication mode, and then communicates with the network side using the second communication mode) and the like.

[0441] (14) Working conditions or KPIs of multiple communication modes of the terminal;

[0442] For example, at least one of the supported waveform, modulation method, coding method, frequency band, power consumption or power, reliability, latency and the like.

[0443] (15) Whether multiple communication modes of the terminal support simultaneous use, and the combination of simultaneous use;

[0444] For example, when mode 1 is working, modes 2 and 3 cannot work; or when mode 1 does not work, modes 2 and 3 can work simultaneously.

[0445] (16) The location of the cell where the terminal is located;

[0446] For example, high-power communication mode can be used for cell edge users.

[0447] (17) The downlink reference signal (such as SSB signal used to select RACH resource) or reference signal group selected by the terminal;

[0448] For example, for random access corresponding to a specific reference signal group, high-power transmission is used for the corresponding PUCCH; for random access corresponding to other reference signal groups, low-power transmission is used for the corresponding PUCCH transmission.

[0449] Under different reference signal groups, the corresponding beam and coverage conditions may be different, so different modes of PUCCH transmission should be used respectively.

[0450] (18) Random access corresponding to at least one of the TRP, frequency, frequency band, sub-band, carrier or synchronization raster selected by the terminal;

[0451] For example, for a random access corresponding to at least one of the following: a specific TRP, a frequency, a frequency band, a sub-band, a carrier, or a synchronization raster, the corresponding PUCCH uses a high-power transmission; for other cases, the corresponding PUCCH transmission uses a low-power transmission.

[0452] Here, the corresponding beams and coverage conditions under different TRPs, frequencies, frequency bands, sub-bands, carriers, or synchronization rasters can be different, so different modes of PUCCH transmission should be used respectively.

[0453] Among them, the pre-defined or pre-configured target rules include one or more of the following:

[0454] (1) If the terminal does not support multiple communication modes for communication, select the legacy mode for PUCCH transmission, otherwise continue to match other rules for next step judgment;

[0455] (2) Determine the available set of communication modes according to the combination that can be used simultaneously by multiple communication modes;

[0456] (3) Select a set from the available set of communication modes according to the features, KPIs, or service requirements currently required by the terminal, such as

[0457] When the terminal's current service requirement is a large flow or high-reliability service, the terminal can determine to send PUCCH and the like in a high-power or high-performance mode;

[0458] When the payload size of the target received or transmitted physical channel meets certain conditions, such as greater than a certain threshold, the terminal can also determine to send PUCCH and the like in a high-power or high-performance mode;

[0460] (4) Determine the PUCCH transmission configuration based on the transmission configuration (reference configuration) of Msg4 or MsgB and the uplink or downlink signal before the random access process, such as:

[0461] (a) The PUCCH uses the same transmission configuration as the uplink signal reference configuration;

[0462] (b) The PUCCH uses the transmission configuration associated with the uplink signal reference configuration, such as

[0463] Based on the communication mode of the reference configuration, map to the target communication mode according to a specific rule;

[0464] Based on the number of repetitions of the reference configuration, map to the target number of repetitions according to certain rules.

[0465] Based on the number of repetitions of the reference configuration, map to the target number of repetitions according to certain rules.

[0471] When the PUCCH has repeated transmission, the determined transmission configuration can be for all transmissions of the PUCCH, or single or multiple transmissions.

[0472] (5) Based on the number of retransmissions of Msg4 or MsgB and the previous uplink or downlink signal in the random access process, determine the transmission configuration of the PUCCH, such as,

[0473] When the number of retransmissions exceeds or does not exceed a certain threshold, the configured or agreed transmission configuration is adopted, including the communication mode.

[0474] (6) Based on the ACK or NACK information of the previous uplink or downlink signal in the random access process, determine the transmission configuration of the PUCCH, such as,

[0476] (7) Based on the MCS or code rate information of the previous uplink or downlink signal in the random access process, determine the transmission configuration of the PUCCH, such as,

[0477] When the MCS or code rate is within a specified range, the configured or agreed transmission configuration is adopted, including the communication mode.

[0478] (8) Based on the scheduling information of Msg4 or MsgB before the random access process, determine the transmission configuration of the PUCCH, such as,

[0481] (9) The measurement quantity of the downlink reference signal determines the transmission configuration of the PUCCH, such as

[0482] When the measurement quantity of the downlink reference signal exceeds or does not exceed a certain threshold, a configured or agreed transmission configuration is adopted, including the communication mode; or

[0483] For example, when the RSRP of the measured associated SSB exceeds or is not less than a certain threshold, the terminal transmits the PUCCH using a low-power consumption mode to save energy.

[0484] (10) The type or state of the random access procedure determines the transmission configuration of the PUCCH, such as

[0487] Or, when the power ramping value or the power ramping accumulation exceeds or does not exceed a certain threshold, a configured or agreed transmission configuration is adopted, including the communication mode.

[0488] (11) Based on whether the random access procedure receives a Backoff Indicator,

[0489] For example, when the terminal receives the backoff indicator, it indicates that the current load is relatively high, and the PUCCH transmission can use higher power transmission to reduce the number of PUCCH retransmissions and repeated transmissions, and save time-frequency resource usage.

[0490] As the fourth sub-example of the above example, based on the condition of the terminal triggering random access, the terminal determines a transmission configuration of the PUCCH, such as

[0491] The reasons for triggering random access include: PDCCH Order, Paging, obtaining SIB, requesting to send resources when uplink resources are insufficient, RLF or BLF, etc.

[0492] The above reasons can be associated with or preferentially associated with a PUCCH transmission configuration;

[0493] The above reasons can be combined with the rules related to service requirements in the third sub-example, such as when the terminal receives paging and the service is a small data MT service, the terminal can use a low-power mode to complete the transmission of PUCCH.

[0494] In some examples, the transmission configuration of PUCCH includes at least one of the following information:

[0495] Target communication mode, communication mode group, or communication mode set for transmitting PUCCH;

[0501] Example group four: transmission of SRS

[0507] TCI state (TCI-State) of SRS, the TCI-State is used to determine the QCL, beam or precoding, path loss, etc. information of SRS.

[0508] In some examples, the terminal determines the transmission configuration of SRS by at least one of the following ways:

[0509] Pre-agreed configuration;

[0510] Determine the transmission configuration of SRS according to the network indication;

[0511] Determine the transmission configuration of SRS according to terminal related information and target rules;

[0512] Based on the condition of triggering SRS.

[0513] As a first sub-example of the above examples, the network and the terminal can pre-agree the transmission configuration of SRS, including the communication mode used, and the terminal and the network respectively transmit and receive according to the pre-agreed configuration.

[0514] As a second sub-example of the above examples, the network can indicate the transmission configuration of SRS to the terminal in the current serving cell or neighbor cell by at least one of the following ways:

[0522] The UE feature can be combined with other UE features to form a feature combination.

[0523] (2) Features, KPIs, service requirements, etc. currently required by the terminal;

[0524] For example, URLLC, NTN, frequency band, early PRACH (the terminal sends PRACH to the network side using the first communication mode before using the second communication mode, and then uses the second communication mode to communicate with the network side), etc.

[0525] (3) Working conditions / KPIs of multiple communication modes of the terminal

[0526] For example, at least one of the supported waveform, modulation method, coding method, frequency band, power consumption / power level, reliability, latency, etc.

[0527] (4) Whether multiple communication modes of the terminal support simultaneous use, and the combination of simultaneous use;

[0528] For example, when mode 1 is working, modes 2 and 3 cannot work; or when mode 1 is not working, modes 2 and 3 can work simultaneously.

[0529] (5) The location of the cell where the terminal is located;

[0530] For example, high-power communication modes can be used for cell edge users.

[0531] (6) The downlink reference signal (such as the SSB signal used to select the RACH resource) or the reference signal group selected by the terminal;

[0532] For example, for a specific reference signal group as an SRS path loss reference signal, the corresponding SRS uses high-power transmission; for other reference signal groups, the corresponding SRS transmission uses low-power transmission.

[0533] Here, the corresponding beam and coverage conditions under different reference signal groups may be different, so different modes of SRS transmission should be used respectively.

[0534] (7) At least one of the TRP, frequency, frequency band, sub-band, carrier, or synchronization raster selected by the terminal for transmitting SRS;

[0535] For example, for a specific TRP, frequency, frequency band, sub-band, carrier, or synchronization raster selected, the corresponding SRS uses high-power transmission; for other cases, the corresponding random access, the corresponding SRS transmission uses low-power transmission.

[0536] Here, the corresponding beam and coverage conditions under different TRPs, frequencies, frequency bands, sub-bands, carriers, or synchronization rasters may be different, so different modes of SRS transmission should be used respectively.

[0537] Among them, the pre-defined or pre-configured target rules include one or more of the following:

[0538] (1) If the terminal does not support multiple communication modes for communication, select the legacy way to send Msg3, otherwise it can continue to match other rules, and proceed to the next step of judgment;

[0539] (2) According to the combination that multiple communication modes can be used at the same time, determine the available set of communication modes;

[0540] (3) According to the feature, KPI, or service requirement currently required by the terminal, select a set from the available set of communication modes, such as,

[0541] When the terminal's current service requirement is large flow or high reliability service, the terminal can determine to send SRS and the like in a high-power or high-performance mode; or

[0542] When the payload size of the target received or transmitted physical channel meets certain conditions, such as greater than a certain threshold, the terminal can also determine to send SRS and the like in a high-power or high-performance mode; or

[0543] When the target received or transmitted physical channel requires a specific waveform, modulation method, coding method, etc., the communication mode that can provide the corresponding service capability can be determined.

[0544] (4) Determine the SRS transmission configuration based on the measurement quantity of the downlink reference signal, such as,

[0545] When the measurement quantity of the downlink reference signal exceeds or does not exceed a certain threshold, the configured or agreed transmission configuration is adopted, including the communication mode.

[0546] As the fourth sub-example of the above example, based on the condition of triggering the terminal to send SRS, the terminal determines a SRS transmission configuration, such as:

[0547] The reasons for triggering SRS transmission include: non-connected state positioning, assisting the network side to obtain the downlink channel based on reciprocity before entering the connected state, etc.

[0548] The above reasons can be associated with or preferentially associated with a SRS transmission configuration;

[0549] The above reasons can be combined with the rules related to service requirements in the third sub-example, such as when receiving Paging and the service is small data MT service, the terminal can use a low-power mode to complete SRS transmission.

[0550] Example Group Five: SRS, Msg3 or SRS Transmission Mode Capability

[0551] To support terminals with different capabilities, and to enable the network to determine whether to configure multiple transmission modes or switch different transmission modes for a particular access terminal, the terminal needs to report or indicate the transmission mode on the target channel or signal.

[0552] In some examples, before determining the target communication module or target communication mode of the target channel or target signal, the terminal reports or indicates at least one of the following capability information (i.e., target capability information):

[0553] Whether the terminal supports one or more communication modules or communication modes;

[0554] The operating conditions or KPIs of the supported communication modules of the terminal, such as supported frequency bands, power consumption or power level, reliability, latency, etc.

[0555] Whether the multiple communication modules of the terminal support simultaneous use, and the combination of simultaneous use;

[0556] Support for data transmission by at least two target communication modules or target communication modes;

[0557] Support for switching between at least two target communication modules or target communication modes.

[0558] In some examples, the terminal target channel or target signal transmission mode capability information is reported in one or more of the following granularities:

[0561] Per band combination;

[0562] Per UE type;

[0563] Per application scenario;

[0564] Per TRP;

[0565] Per cell;

[0566] Per reference signal group or per reference signal, such as the reference signal or reference signal group selected by the terminal for random access resource determination or the reference signal group in which it is located.

[0567] In some examples, the terminal indicates or reports or requests the target channel or target signal transmission mode capability by one or more of the following methods:

[0568] Report or request through PRACH signal, such as through specific RO or PRACH preamble or specific feature combination corresponding to PRACH resource after combination with other features, to indicate or report or request, PRACH can be MsgA PRACH or Msg1 PRACH;

[0569] Indicate or report or request through WUS or SRS signal;

[0570] Indicate or report or request through resource, information or bit of Msg3 PUSCH;

[0571] Indicate or report or request through resource, information or bit of MsgA PUSCH;

[0572] Indicate or report or request through additional defined specific signal;

[0573] Different sending time windows of one or more of the above uplink signals or channels indicate or report or request the corresponding target signal channel transmission mode of the UE; for example, when all uplink and downlink signals through RIS and uplink and downlink signals not through RIS are in different time windows, the network can determine that the terminal sending the WUS signal has the transmission capability of the target signal channel corresponding to the window based on the specific uplink signal (such as WUS signal) received in the different time windows;

[0574] Report or request through RRC signaling, such as for connected terminals, the normal UE capability report RRC signaling can be used to indicate or report or request the related transmission mode according to the granularity defined in any of the above.

[0575] In some examples, the target channel or target signal is one or more of the following:

[0576] SRS;

[0577] Msg3;

[0578] Common PUCCH, such as PUCCH channel for Msg4 or MsgB PDSCH hybrid automatic repeat request (HARQ) feedback;

[0579] Other uplink reference signals or channels in random access procedures.
