[0004] Currently, in order to save the deployment cost of network-side devices, some scenarios allow network-side devices to only receive data but not send data.

[0005] In a scenario where uplink and downlink transmissions are decoupled, network-side devices can typically only receive uplink information from user equipment (UE) without sending downlink synchronization reference signals, such as synchronization signal / physical broadcast channel blocks (SS / PBCH blocks, SSBs).

[0038] The following explains the concepts, nouns or coined words involved in the embodiments of this application.

[0039] 1. Uplink and downlink decoupling

[0040] Due to factors such as the New Radio (NR) uplink and downlink time slot allocation and the significant difference in uplink and downlink power between user equipment and base stations, uplink and downlink coverage in frequency bands like 3.5G and 4.9G is unbalanced. Limited uplink coverage has become a bottleneck for 5G deployment. To address this issue, NR uplink and downlink decoupling defines a new spectrum pairing method, allowing downlink data to be transmitted in frequency bands like 3.5G and 4.9G, while uplink data is transmitted on lower frequencies like 1.8G, thereby improving uplink coverage.

[0041] 2. Transmit and Receive Point (TRP)

[0042] TRP refers to an antenna array consisting of one or more antenna elements that can be used for a network in a specific area and at a specific geographical location. In NR, a base station can have one or more TRPs.

[0043] 3. Physical Random Access Channel (PRACH)

[0044] PRACH is the access channel when the UE initiates a call. After receiving the PRACH response message, the UE will send a Radio Resource Control (RRC) Connection Request message on the PRACH channel according to the information indicated by the base station to establish an RRC connection.

[0045] Specifically, during the random access process of the UE, the UE sends a random access preamble code through the PRACH channel, starts trying to access the network, and establishes a basic signaling connection with the network.

[0046] 4. Random access process

[0047] In the prior art, the random access process can be a contention-based or non-contention-based random access process. The random access process can be divided into a 4-step random access process (also called a Type-1 random access process) and a 2-step random access process (also called a Type-2 random access process) based on the process.

[0048] In NR Rel-15, the contention-based four-step random access process is as follows: the UE first sends Msg1, the random access preamble, to the network. After the network detects the preamble, it sends Msg2, the Random Access Response (RAR), which contains the preamble number detected by the network, namely the RAPID (RACH preamble ID), the uplink PUSCH resources allocated to the UE for sending Msg3 (UL grant information), the temporary cell-radio network temporary identifier (TC-RNTI), and the timing advance (TA) command. After receiving Msg2, if the UE confirms that at least one of the preamble numbers carried in Msg2 matches the preamble number it sent, it sends Msg3 containing contention resolution information based on the uplink resources indicated in the RAR. If the network does not receive Msg3, the uplink physical shared channel (PUSCH) can be scheduled in the PDCCH scrambled by the TC-RNTI. After receiving Msg3, the network will send Msg4 containing contention resolution information. After receiving Msg4, the UE confirms that the resolution information is consistent with the one sent in Msg3, thus completing the 4-step random access.

[0049] 5. Contention-based random access process

[0050] For the contention-based random access process, different UEs randomly select preambles for transmission. In this way, different UEs may select the same preamble to send at the same random access opportunity. This situation can be understood as a UE preamble conflict. At this time, different UEs will receive the same RAR, and different UEs will transmit Msg3 PUSCH according to the scheduling information of the uplink (UL) authorization (UL grant) in the RAR. However, the network can only decode the PUSCH (including contention resolution information) sent by one UE on one Msg3 PUSCH scheduling resource. The network will include the contention resolution information received in Msg3 in Msg4. If the contention resolution information received by the UE in Msg4 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, the contention resolution is considered unsuccessful. If the contention resolution is unsuccessful, the UE reselects the PRACH transmission resource, sends the PRACH, and makes the next random access attempt.

[0051] In NR Rel-16, the 2-step random access procedure (2-step RACH) was introduced. The first step is that the UE sends message A (MsgA) to the network side. After receiving MsgA, the network side sends MsgB message to the UE. If the UE does not receive MsgB within a certain period of time, the UE will increment the counter that counts the number of times MsgA is sent and resend MsgA. If the counter that counts the number of times MsgA is sent reaches a certain threshold, the UE will switch from the 2-step random access procedure to the 4-step random access procedure. MsgA includes the MsgA preamble part and the MsgA PUSCH part. The preamble part is sent on the random access channel opportunity (RACH Occasion, RO) used for 2-step RACH, and the PUSCH part is sent on the MsgA PUSCH resources associated with the sent MsgA preamble and RO. The MsgA PUSCH resources are a group of PUSCH resources configured relative to each PRACH slot, including time-frequency resources and demodulation reference signal (DMRS) resources.

[0052] 6. Non-contention-based random access process

[0053] In addition to contention-based random access initiated by the UE or the network, when the network measurement finds that the uplink is out of sync or the uplink service has not been sent for a long time, the network can trigger a non-contention random access process. Specifically, the network sends downlink control information (DCI) to the UE. The DCI carries a PDCCH order. Currently, the PDCCH order contains at least the following parameters: field, DCI format identifier, frequency domain resource allocation, random access preamble index, UL / SUL indicator, SS / PBCH indicator, PRACH mask index, and reserved bit. It can be understood that the UE can determine the RO of the PRACH by interpreting the PDCCH order, and the preamble determines the PRACH transmission.

[0054] 7. Random access resource selection

[0055] In NR, a cell can configure multiple frequency division multiplexing (FDM) PRACH transmission occasions (Physical Random Access Channel transmission occasions, or PRACH occasions, referred to as ROs) at a single PRACH transmission time domain location. The number of ROs that can be FDMed at a given moment can be: {1, 2, 4, 8}. At a given moment, there are eight RO resources distributed across different frequency domain resources.

[0056] The preamble can only be transmitted on the time domain resources (i.e., RO resources) configured by the high-level parameter PRACH Configuration Index, and can only be transmitted on the frequency domain resources configured by the high-level parameter PRACH-FDM, where M is the high-level parameter PRACH-FDM. During initial access, the PRACH frequency domain resources are numbered in ascending order starting from the lowest-frequency RO resource within the initial active uplink bandwidth part. Otherwise, the PRACH frequency domain resources are numbered in ascending order starting from the lowest-frequency RO resource within the active uplink bandwidth part. RO resources are numbered from low to high frequency, RO#0 to RO#7.

[0057] In NR, there is an association between the RO and the synchronization signal / physical broadcast channel block (SS / PBCH block, SSB) actually sent. The synchronization signal / physical broadcast channel block can also be referred to as the synchronization signal block (SS Block). One SSB may be associated with multiple ROs, or multiple SSBs may be associated with one RO (in this case, different SSBs correspond to different preamble codes). Generally, the base station can use different beams to send different SSBs, and the corresponding UE sends the preamble on the RO associated with the SSB. In this way, the UE selects the RO or RO plus preamble combination associated with the SSB with good RSRP strength based on the reference signal receiving power (RSRP) strength of the received SSB, and sends the preamble. In this way, the network can determine the SSB selected by the UE based on the RO or RO plus preamble combination of the received preamble. The network then sends Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0058] In some examples, the number of FDM ROs at a time is 8, and the number of SSBs actually transmitted is 4, namely SSB#0, SSB#1, SSB#2, and SSB#3, with each SSB associated with two ROs. If the UE determines to send the preamble on the RO corresponding to SSB#0, the UE can select an RO between RO#0 and RO#1 to send the PRACH.

[0059] In other examples, the number of ROs of FDM at a time is 2, and the number of SSBs actually transmitted is 8, namely SSB#0, SSB#1, ..., SSB#7, and every 2 SSBs are associated with 1 RO. When multiple SSBs share one RO, the preamble sets associated with the multiple SSBs are different (the same preamble cannot belong to the preamble set 0 associated with different SSBs at the same time). Taking RO#0 as an example, it has 60 preambles associated with SSBs, of which preambles with indexes 0 to 29 are associated with SSB#0, and preambles with indexes 30 to 59 are associated with SSB#1.

[0060] Before transmitting PRACH, the UE first performs resource selection. Based on the RSRP of the received SSB, it selects an SSB with an RSRP above a threshold. If multiple SSBs have RSRPs above the threshold, the terminal can select any SSB with an RSRP above the threshold. If no SSB has an RSRP above the threshold, the UE selects an SSB based on the implementation. Based on the network-side configuration, the UE obtains the correspondence between SSBs and ROs. After selecting an SSB, the RO corresponding to the selected SSB is used as the RO for transmitting PRACH / Preamble. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs for PRACH / Preamble transmission.

[0061] In some examples, combined with the above examples, assuming that the UE selects SSB#1, the UE can select one from RO#2 and RO#3 for PRACH / Preamble transmission; if the UE selects SSB#1, the UE can select the available RO closest to the current time in the RO (RO#0 or #4) associated with SSB#1 for PRACH / Preamble transmission. Furthermore, in the selected RO, the UE selects a preamble from the preamble set associated with the selected SSB for PRACH transmission. For example, if an RO is associated with 2 SSBs, then in the available preamble set associated with the SSB in an RO, the preamble will be divided into two subsets, each subset corresponding to one SSB. The UE will select a preamble sequence in the preamble subset corresponding to the selected SSB for PRACH transmission.

[0062] 8. RAR

[0063] The RAR in NR is carried by the Medium Access Control (MAC) sub-protocol data unit (subPDU). There are three types of MAC RAR subPDUs:

[0064] The first subPDU is used for backoff indication and consists of a MAC subheader. The specific structure is shown in Figure 2A. "E" is the extension field, which indicates whether this subPDU is the last subPDU in the MAC PDU; a value of 0 indicates it is the last; "T" is set to 0; "R" is a reserved bit; and "BI" indicates the cell's overhead condition. It should be noted that if this subPDU is transmitted, it must appear at the very beginning of the RAR MAC PDU.

[0065] The second subPDU is used to request System Information (SI). It contains only a subheader that carries the RAPID. The specific structure is shown in Figure 2B. "E" is the extension field, which indicates whether this subPDU is the last subPDU in the MAC PDU. If it is 0, it means it is the last one; "T" is set to 1; and "RAPID" is used to carry the RAPID.

[0066] The third subPDU indicates RAPID with MAC RAR and consists of a MAC subheader carrying RAPID and a MAC RAR. The specific structure is shown in Figure 2C. In the MAC RAR, "R" is a reserved bit; "TA command" indicates the timing advance; "UL Grant" indicates the resource scheduling information for the first PUSCH (i.e., Msg3) of the RAR; and "TC-RNTI" carries the TC-RNTI.

[0067] The 27 bits of "UL Grant" contain 6 fields:

[0068] Frequency hopping flag (1 bit): used to indicate whether PUSCH is enabled for frequency hopping;

[0069] PUSCH frequency domain resource allocation (14 bits): used to indicate the frequency domain scheduling position of PUSCH and the offset of frequency hopping (offset, if frequency hopping is enabled);

[0070] PUSCH time domain resource allocation (4 bits): used to indicate the time domain scheduling position of PUSCH;

[0071] Modulation and Coding Scheme (MCS) (4 bits): used to indicate the MCS level, where the selection of the MCS table depends on whether transform precoding is enabled;

[0072] PUSCH Transmit Power Control (TPC) command (3 bits): used to indicate the power step size parameter {-6, -4, -2, 0, 2, 4, 6, 8} dB;

[0073] Channel State Information (CSI) request (1 bit): Reserved bit. 9. RAR window

[0074] After sending the preamble on the RO, the UE monitors the PDCCH that schedules the random access response message Msg2 / B in the RAR window. The starting position of the RAR window is the earliest control resource set (CORESET) used to receive the PDCCH after the last symbol of the PRACH transmission opportunity. The PDCCH is configured by the type 1-PDCCH common search space (CSS) set. The length of the RAR window is configured by the RRC.

[0075] It should be noted that a CORESET is a set of physical resources within a specific area of ​​the downlink resource grid used to carry PDCCH or DCI. NR PDCCH is specifically designed to be transmitted in a configurable control resource set.

[0076] The uplink transmission method provided in the embodiment of the present application can be applied to a scenario where a UE sends a PRACH to perform random access.

[0077] In related technologies, when a UE performs random access by sending a PARCH to a network device that does not transmit a downlink synchronization reference signal (e.g., SSB), the UE cannot determine the PRACH transmission beam and path loss by measuring the downlink synchronization reference signal. Consequently, the UE cannot determine the beam information and transmit power used when transmitting the PRACH, resulting in the UE being unable to correctly transmit the PRACH.

[0078] In the uplink transmission method provided in the embodiment of the present application, for a network-side device that does not transmit a downlink synchronization reference signal (e.g., SSB), when a UE transmits a PARCH to the network-side device for random access, the UE can obtain relevant configuration information for uplink transmission, such as transmission resource information, transmission power-related information, and transmission beam information. The UE can then transmit the PRACH based on the above-mentioned relevant configuration information. In this way, the UE can transmit the PRACH according to the relevant configuration information, thereby correctly transmitting the PRACH.

[0079] The uplink transmission method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0080] FIG3 is a flow chart of an uplink transmission method provided in an embodiment of the present application. As shown in FIG3 , the uplink transmission method may include the following steps S201 and S202:

[0081] Step S201: The UE obtains first information.

[0082] Among them, the above-mentioned first information is the relevant configuration information of uplink transmission, and the above-mentioned first information includes at least one of the following: sending resource information, sending power related information, and sending beam information.

[0083] In some embodiments of the present application, the first information is pre-configured information or information configured by a network-side device.

[0084] In some embodiments of the present application, the network-side device may be a TRP. The serving cell in which the UE resides may be configured with multiple TRPs, at least one of which may be a first TRP capable of sending downlink information. The UE may receive configuration information related to uplink transmission from the first TRP (i.e., first information) and perform uplink transmission based on the configuration information.

[0085] For example, the serving cells of the UE include TRP1, TRP2, and TRP3. TRP1 and TRP2 can receive data but are not allowed to send data, and TRP3 can transmit data (e.g., send data). After TRP3 sends relevant configuration information of uplink transmission to the UE, the UE can receive the relevant configuration information of uplink transmission from TRP3 and perform uplink transmission according to the relevant configuration information.

[0086] It is understandable that the uplink transmission method provided in the embodiment of the present application can be applied to the multi-TRP scenario. In the multi-TRP scenario, the serving cell can schedule resources for the UE from multiple TRPs, thereby providing better coverage and data rate.

[0087] In some embodiments of the present application, the above-mentioned sending resource information includes at least one of time domain resources and frequency domain resources.

[0088] In some embodiments of the present application, the above-mentioned sending resource information includes at least one of the following: random access opportunity RO, RO window or RO group, timing advance (TA), and timing advance group (TAG).

[0089] In some embodiments, the beam information (i.e., the above-mentioned transmission beam information) may include at least one of the following: 1) whether different beams are used for transmission; 2) reference signals, antenna ports, antenna panel information, etc. for determining the beam direction.

[0090] In some embodiments, the UE may determine the first transmission resource for performing uplink transmission based on the transmission resource information. For example, when the first information includes the transmission resource information, the UE may determine the transmission resource information as the first transmission resource.

[0091] Exemplarily, the UE may determine the first transmission resource for performing uplink transmission according to the RO window or group configuration sent by the network side device. Exemplarily, the UE may use different beams to transmit uplink information on different ROs, such as PRACH.

[0092] In some embodiments of the present application, the above-mentioned transmit power-related information includes at least one of the following: transmit power, power offset value, and path loss information.

[0093] In some embodiments, when the first information includes transmit power, the UE may determine the transmit power as the transmit power of uplink transmission.

[0094] Exemplarily, the network side device configures the transmit power to be the maximum transmit power minus X dB, and the UE may determine the transmit power of uplink transmission to be the maximum transmit power minus X dB, where X is greater than 0. For example, X dB may be 3 dB.

[0095] In some embodiments, the power offset value is a power offset value of the transmit power for sending the second uplink information compared to the transmit power for sending the first uplink information. Exemplarily, the first uplink information may be a PRACH associated with an SSB initiated by the UE, or the first uplink information may be a PRACH associated with an SSB triggered by a PDCCH command, and the second uplink information may be a PRACH associated with an uplink reference signal triggered by a PDCCH command.

[0096] In some embodiments, the network side device configures a power offset value for the transmission power of the second uplink information compared to the transmission power of the first uplink information, and the UE can determine the transmission power for the second uplink information based on the transmission power and power offset value for the first uplink information.

[0097] In some embodiments, when the first information includes transmit power related information and the transmit power related information includes a power offset value, the UE may determine the first transmit power for uplink transmission based on the power offset value.

[0098] Exemplarily, the UE may determine the sum of the transmit power of the first PRACH and the power offset value as the first transmit power. It is understood that the first transmit power may be the transmit power of the second PRACH, expressed as: P(second PRACH transmit power) = P(first PRACH transmit power) + power offset value, where P(first PRACH transmit power) is the transmit power of the PRACH on which the RAR was last successfully detected.

[0099] It can be understood that the second uplink information may be uplink information that needs to be sent when the UE currently performs uplink transmission.

[0100] In some embodiments, when the first information includes transmit power related information, and the transmit power related information includes a power offset value and path loss information, the UE may determine the first transmit power for uplink transmission based on the power offset value and the path loss information.

[0101] Exemplarily, the UE may determine the sum of the UE's target received power, the reference path loss (i.e., path loss information), and the power offset value as the PRACH transmit power, expressed as PRACH transmit power P=P(target received power)+reference path loss+first power offset value.

[0102] It should be noted that the above-mentioned target received power is the maximum received power when the UE receives a signal, and the above-mentioned reference path loss can also be obtained based on a reference path loss measurement reference signal.

[0103] In some embodiments, the first information further includes first indication information, where the first indication information is used to indicate whether the power offset value is effective. Exemplarily, the UE may receive an RRC message from a network-side device, where the RRC message is used to configure the power offset value, and receive a DCI from the network-side device, where the DCI indicates that the configured power offset value is effective.

[0104] Exemplarily, the UE receives signaling (such as DCI) from a network-side device, which triggers PRACH transmission. The signaling contains 1 bit of indication information, which indicates whether a power offset value is to be applied to the power of the activated PRACH, that is, whether a power offset value is to be applied when determining the transmit power of the PRACH.

[0105] In an embodiment of the present application, the network side device can indicate whether the configured power offset value is effective. If it is indicated that the power offset value is effective, the UE can determine the first transmit power of the uplink transmission based on the power offset value.

[0106] Exemplarily, the network side device may be a base station or a core network device.

[0107] In some embodiments of the present application, the first information is associated with a sounding reference signal SRS; or,

[0108] The first information is associated with a channel state information reference signal CSI-RS; or,

[0109] The first information is associated with the random access opportunity RO.

[0110] In some embodiments, the network side device can configure the association relationship between the first information and SRS, or configure the association relationship between the first information and CSI-RS, or configure the association relationship between the first information and RO, and then send the first information to the UE so that the UE can determine the relevant configuration for performing uplink transmission based on the first information.

[0111] Exemplarily, when the UE sends an SRS, the UE may determine the transmission resources associated with the SRS as the transmission resources for performing uplink transmission; or, the UE may determine the transmission power associated with the SRS as the transmission power for performing uplink transmission; or, the UE may determine the transmission beam associated with the SRS as the transmission beam for performing uplink transmission.

[0112] Exemplarily, in the case where the UE determines the RO to send PRACH, the UE may determine the transmission resources associated with the RO as the transmission resources for performing uplink transmission; or, the UE may determine the transmission power associated with the RO as the transmission power for performing uplink transmission; or, the UE may determine the transmission beam associated with the RO as the transmission beam for performing uplink transmission.

[0113] Step S202: The UE performs uplink transmission based on the first information.

[0114] In some embodiments of the present application, the UE can determine at least one of the transmission resources, transmission power, and transmission beam for performing uplink transmission based on the above-mentioned first information, and perform uplink transmission according to at least one of the transmission resources, transmission power, and transmission beam.

[0115] It can be understood that performing uplink transmission refers to sending uplink information, ie, an uplink signal or an uplink channel, to a network-side device.

[0116] In an uplink transmission method provided in an embodiment of the present application, a UE obtains first information, which is configuration information related to uplink transmission. The first information includes at least one of the following: transmission resource information, transmission power related information, and transmission beam information. The UE performs uplink transmission based on the first information. Through this method, the UE can obtain information such as transmission resource information, transmission power related information, and transmission beam information for uplink transmission, and perform uplink transmission based on the above information. When the UE transmits uplink data to a network-side device, it can determine the transmission resource, transmission power, or transmission beam for performing the uplink transmission based on the configuration information related to the uplink transmission, thereby correctly performing the uplink transmission.

[0117] In some embodiments of the present application, the first information includes transmit power related information, and the transmit power related information includes a power offset value; illustratively, step S202 may include the following steps S202a and S202b:

[0118] Step S202a: The UE determines a first transmit power according to the first power and the power offset value.

[0119] Step S202b: The UE performs uplink transmission according to the first transmission power.

[0120] Among them, the above-mentioned first power is the UE's receiving power or the first transmitting power, the above-mentioned first transmitting power is the transmitting power of the UE sending the first channel, and the above-mentioned first channel is any one of the following: an uplink synchronization channel associated with a downlink synchronization signal, an uplink synchronization channel sent to the first network side device; the above-mentioned first network side device is a network side device with downlink synchronization signal transmission.

[0121] It should be noted that the explanation of the above power offset value can be found in the relevant description above and will not be repeated here.

[0122] In some embodiments, the downlink synchronization signal may be SSB.

[0123] In some embodiments, the uplink synchronization channel may be a PRACH.

[0124] In some embodiments, the first network-side device may be a base station.

[0125] For example, taking the first channel as PRACH associated with SSB as an example, the UE can calculate the sum of the transmit power and the power offset value of the PRACH that successfully detected the RAR last time, and determine the sum of the transmit power and the power offset value of the PRACH as the first transmit power, and then use the first transmit power to send the PRACH.

[0126] In an embodiment of the present application, the UE can determine the transmit power of the PRACH to be sent currently based on the transmit power and power offset value of the PRACH that successfully detected the RAR last time, so that the UE can determine the transmit power of the PRACH sent this time based on the transmit power and power offset value of the PRACH that was successfully sent last time, thereby being able to accurately determine the transmit power of the PRACH.

[0127] In some embodiments of the present application, the above step S201 can be implemented by the following step S201a.

[0128] Step S201a: The UE receives a first message from a network-side device.

[0129] Among them, the above-mentioned first message includes first information.

[0130] In some embodiments, the first message includes any one of the following: a physical downlink control channel PDCCH command, a random access response message RAR, and system information.

[0131] In some embodiments, the above-mentioned PDCCH command may be a signaling sent by a network side device for triggering PRACH.

[0132] In some embodiments, the RAR is a message sent by a network-side device in response to Msg1 (or PRACH). For example, the RAR may be Msg2 or MsgB.

[0133] In some examples, taking the first message as a PDCCH command as an example, the network-side device sends a PDCCH command to the UE, where the PDCCH command is used to trigger PRACH transmission, and the PDCCH signaling includes at least one of the following information: PRACH transmission power information, PRACH transmission beam information, PARCH transmission behavior information, and PRACH resource information. Exemplarily, the power information sent by the PRACH may include path loss information and power offset information; the PRACH transmission behavior information may include PRACH transmission beam information; the PARCH transmission behavior information may include using one beam or using multiple beams for transmission; the PRACH resource information may be an RO group or RO window for sending PRACH. The UE can determine information such as the transmission power, transmission resources, and transmission beam when sending PRACH based on the above information in the PDCCH signaling.

[0134] In some examples, taking the first message as an RAR as an example, the network-side device sends a RAR message to the UE, where the RAR message indicates allocation of at least one uplink resource (e.g., an uplink PUSCH resource) for the UE to send Msg3, and the RAR message includes at least one of the following information: at least one TA associated with the at least one uplink resource, at least one power information associated with the at least one uplink resource, and TAG information associated with the at least one uplink resource. The UE can determine the uplink resource for subsequent transmission of Msg3 based on the uplink resource from the network-side device, determine the transmit power when sending Msg3 based on the power information associated with the uplink resource, and determine the timing advance when sending Msg3 based on the TA or TAG associated with the uplink resource.

[0135] In an embodiment of the present application, the network side device can indicate the relevant configuration when the UE sends uplink information (such as PRACH or Msg3) in the PDCCH signaling or RAR, so that the UE can determine the relevant configuration of subsequent information transmission based on the indication of the network side device, and because the relevant information sent by the network side device to the UE is reused to indicate the relevant configuration, it avoids adding new wireless signaling to indicate the UE uplink transmission related configuration, thereby improving the utilization of wireless resources.

[0136] In some embodiments of the present application, the uplink transmission method may include the following steps S203:

[0137] Step S203: The UE receives second indication information from the network-side device.

[0138] The second indication information is used to indicate that the first information is carried in the first message.

[0139] In some embodiments, the network side device can send a second indication information to the UE to indicate that the first information is carried in the first message. After receiving the first information, the UE can parse the first information from the first message according to the indication of the second indication information to perform uplink transmission according to the first information.

[0140] For example, taking the first message as a RAR message, the network side device can send an indication information to indicate that the RAR message carries relevant configuration information of the uplink transmission. After receiving the RAR message sent by the network side device, the UE parses the RAR message to obtain relevant configuration information of the uplink transmission.

[0141] For example, the UE receives an RRC configuration, where the RRC configuration indicates the number of first messages included in the RAR.

[0142] It should be noted that the above step S203 can be performed before the above step S201, or the above step S203 can be performed simultaneously with the above step S201, or the above step S203 can be performed after the above step S201.

[0143] In an embodiment of the present application, the network side device can indicate that the relevant configuration information of the uplink transmission is carried in the first message, so that the UE can parse the relevant configuration information of the uplink transmission from the first message based on the instruction of the network side device, thereby further ensuring that the UE obtains the relevant configuration information of the uplink transmission.

[0144] In some embodiments of the present application, the above step S202 may include the following step S202c:

[0145] Step S202c: The UE performs uplink transmission of the second message based on the first information.

[0146] It can be understood that the UE performing uplink transmission of the second message refers to: the UE sending the second message to the network side device.

[0147] The second message includes any one of the following: physical random access channel PRACH, public physical uplink control channel PUCCH, public physical uplink shared channel PUSCH, Msg1, Msg3.

[0148] For example, taking the second message as PRACH as an example, after obtaining the relevant configuration information of the uplink transmission, the UE can determine the resources, beam and transmission power of the uplink transmission based on the above relevant configuration information, and use the above transmission power to use the beam to send PRACH through the uplink transmission resources.

[0149] In an embodiment of the present application, the UE can determine the resources, beams or transmission power when sending uplink information such as PRACH, PUCCH, PUSCH, etc. based on the relevant configuration information of the uplink transmission, without relying on the downlink synchronization signal to determine, thereby enabling the uplink information to be correctly sent even when the network side device does not send a downlink synchronization signal.

[0150] In some embodiments of the present application, the first information includes sending resource information; illustratively, the step S202 may include the following step S202d:

[0151] Step S202d: The UE selects an RO based on the above-mentioned sending resource information, and uses the selected RO to perform uplink transmission.

[0152] In some embodiments, when the transmission resource information includes at least one transmission resource, the UE may determine resources for uplink transmission from the at least one transmission resource.

[0153] In some embodiments, the resources used for uplink transmission may be indicated by a network-side device, or the resources used for uplink transmission may be predefined by a protocol.

[0154] Exemplarily, when the sending resources include RO#0, RO#1, RO#2 and RO#3, if the network side device instructs to perform uplink transmission in RO#2, the UE can select RO#2 from the above multiple ROs to send uplink information.

[0155] Exemplarily, when the transmission resources include RO#0, RO#1, RO#2 and RO#3, if the protocol predefines uplink transmission in the first RO, the UE can select RO#0 from the above multiple ROs to send uplink information.

[0156] In an embodiment of the present application, when the UE performs uplink transmission, it can obtain the sending resource information of the uplink transmission and select the uplink resource based on the sending resource information, so that the UE can determine the sending resource without relying on the downlink synchronization signal, thereby being able to correctly send uplink information even when the network side device does not send the downlink synchronization signal.
