[0036] The following explains the concepts, nouns, or coined words involved in the embodiments of this application.

[0037] 1. Uplink and downlink decoupling

[0038] Due to reasons such as the large difference in the uplink and downlink time slot ratios of the New Radio (NR) and the uplink and downlink power differences between user equipment and base stations, the uplink and downlink coverage of frequency bands such as 3.5G / 4.9G is unbalanced, and the limited uplink coverage has become a bottleneck for 5G deployment. To solve the above problems, the uplink and downlink decoupling of NR defines a new spectrum pairing method, enabling downlink data to be transmitted in frequency bands such as 3.5G / 4.9G, while uplink data is transmitted in low frequencies such as 1.8G, thereby improving the uplink coverage.

[0039] 2. Transmit And Receive Point (TRP)

[0040] A TRP refers to an antenna array that contains one or more antenna elements and can be used for a network in a specific geographical location in a specific area. In NR, a base station can have one or more TRPs.

[0041] 3. Physical Random Access Channel (PRACH)

[0042] The PRACH is the access channel when the UE initiates a call at the beginning. 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.

[0043] Specifically, in the random access process of the UE, the UE sends a random access preamble through the PRACH channel to start attempting to access the network and establish a basic signaling connection with the network.

[0044] 4. Random Access Process

[0045] In the prior art, the random access process can be a random access process based on competition or non - competition. Classified according to the process, the random access process can be divided into a 4 - step random access process (also called Type - 1 random access process) and a 2 - step random access process (also called Type - 2 random access process).

[0046] In NR Rel-15, the 4-step contention-based random access procedure is as follows: The UE first sends Msg1, i.e., the random access preamble, to the network. After detecting the preamble, the network will send Msg2, i.e., the Random Access Response (RAR) message, which contains the preamble number detected by the network, i.e., the RAPID (RACH preamble ID), the uplink PUSCH resource (UL grant information) allocated to the UE to send Msg3, the Temporary Cell - Radio Network Temporary Identity (TC-RNTI), the Timing Advance (TA) command, etc. After receiving Msg2, if the UE confirms that at least one of the preamble numbers carried in Msg2 is the same as the preamble number it sent, it will send Msg3 containing the contention resolution information according to the uplink resources indicated in the RAR. If the network does not receive the Msg3 Physical Uplink Shared Channel (PUSCH), it can schedule the retransmission of the Msg3 PUSCH in the PDCCH scrambled with the TC-RNTI. After receiving Msg3, the network will send Msg4 containing the contention resolution information. After receiving Msg4, the UE confirms that the resolution information is the same as what it sent in Msg3, and then the 4-step random access is completed.

[0047] 5. Contention-based Random Access Procedure

[0048] For the contention-based random access procedure, 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 preamble collision among UEs. At this time, different UEs will receive the same RAR, and different UEs will perform the transmission of Msg3 PUSCH according to the scheduling information of the uplink (UL) grant in the RAR. However, the network can only decode the PUSCH (containing the contention resolution information) sent by one UE on a 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 the contention resolution successful. If they do not match, the contention resolution is considered unsuccessful. If the contention resolution is unsuccessful, the UE re-selects the PRACH transmission resource, performs PRACH transmission, and makes the next random access attempt.

[0049] In NR Rel-16, the 2-step random access procedure (2-step RACH) is introduced. The first step is that the UE sends Message A (MsgA) to the network side. After receiving MsgA, the network side sends MsgB to the UE. If the UE does not receive MsgB within a certain time, the UE will increment the counter that counts the number of MsgA transmissions and re-send MsgA. If the counter that counts the number of MsgA transmissions reaches a certain threshold, the UE will switch from the 2-step random access procedure to the 4-step random access procedure. MsgA includes a MsgA preamble part and a 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 resource associated with the transmitted MsgA preamble and RO. Among them, the MsgA PUSCH resource is a set of PUSCH resources configured for each PRACH slot, including time-frequency resources and demodulation reference signal (De-Modulation Reference Signal, DMRS) resources.

[0050] 6. Non-competitive random access procedure

[0051] In addition to the UE- or network-initiated contention-based random access, when the network measures and finds that the uplink is out of sync or the uplink traffic has not been sent for a long time, the network can trigger the non-competitive random access procedure. Specifically, the network sends downlink control information (Downlink Control Information, DCI) to the UE, and this DCI carries a PDCCH command (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 bits. 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.

[0052] 7. Random access resource selection

[0053] In NR, a cell can configure multiple frequency-division multiplexing (FDM) physical random access channel transmission occasions (PRACH occasions) at a time-domain position for transmitting PRACH, which is also simply called an RO. At a certain moment, the number of ROs that can be FDM can be: {1, 2, 4, 8}. At a certain moment, 8 RO resources are distributed on different frequency-domain resources.

[0054] The preamble can only be transmitted on the time-domain resources (i.e., RO resources) configured by the high-layer parameter PRACH configuration index, and can only be transmitted on the frequency-domain resources configured by the high-layer parameter PRACH-FDM, where M is the high-layer parameter PRACH-FDM. At initial access, the frequency-domain resources of the PRACH are numbered in ascending order starting from the RO resource with the lowest frequency within the initial active uplink bandwidth part, otherwise the frequency-domain resources of the PRACH are numbered in ascending order starting from the RO resource with the lowest frequency within the active uplink bandwidth part. The RO resources are numbered as RO#0 to RO#7 in ascending order of frequency.

[0055] In NR, there is an association relationship between an RO and the actually transmitted synchronization signal / physical broadcast channel block (SS / PBCH block, SSB), which can also be simply called a synchronization signal block (SS Block). One SSB may be associated with multiple ROs, or multiple SSBs may be associated with 1 RO (in this case, different SSBs correspond to different preamble codes). Usually, the base station can use different beams to transmit different SSBs, and the corresponding UE transmits the preamble on the RO associated with the SSB. In this way, the UE selects the RO or the RO plus preamble combination associated with the SSB with good reference signal receiving power (RSRP) intensity according to the RSRP intensity of the received SSB to transmit the preamble. In this way, the network can determine the SSB selected by the UE based on the received RO or the RO plus preamble combination of the preamble. Then the network transmits Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0056] In some examples, the number of ROs of FDM at a moment is 8, and the number of actually transmitted SSBs is 4, namely SSB#0, SSB#1, SSB#2, SSB#3, and each SSB is associated with 2 ROs. If the UE determines to send a Preamble on the RO corresponding to SSB#0, then the UE can select one of RO#0 and RO#1 to send the PRACH.

[0057] In other examples, the number of ROs of FDM at a moment is 2, and the number of actually transmitted SSBs 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 sets associated with different SSBs at the same time). Taking RO#0 as an example, it has 60 preambles associated with SSBs, where the preambles with indices 0 to 29 are associated with SSB#0, and the preambles with indices 30 to 59 are associated with SSB#1.

[0058] Before the UE sends the PRACH, it first performs resource selection. First, according to the RSRP of the received SSB, it selects the SSB with an RSRP higher than the threshold; if there are multiple SSBs with an RSRP higher than the threshold, the terminal can select any SSB with an RSRP higher than the threshold; when there is no SSB with an RSRP higher than the threshold, the UE selects an SSB based on the implementation. Based on the configuration of the network side, the UE obtains the correspondence between the SSB and the RO; after selecting the SSB, the RO corresponding to the selected SSB is used as the RO for sending the PRACH / Preamble. If the selected SSB is associated with multiple ROs, the terminal can select one of them to send the PRACH / Preamble.

[0059] In some examples, in combination with the above examples, assuming that the UE selects SSB #1, the UE can select one of RO #2 and RO #3 for PRACH / Preamble transmission; if the UE selects SSB #1, the UE can select the available RO with the closest distance to the current time among the ROs associated with SSB #1 (RO #0 or #4) for PRACH / Preamble transmission. Further, 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 preambles will be divided into two subsets, each subset corresponding to an SSB. The UE will select a certain preamble sequence from the preamble subset corresponding to the selected SSB for PRACH transmission.

[0060] 8. RAR

[0061] 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:

[0062] The first type of subPDU is for backoff indication. It consists of a MAC subheader, and the specific structure is as Figure 2A shown. Among them, "E" is the extension field, which is used to indicate 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 0; "R" is the reserved bit; "BI" is used to indicate the overhead condition of the cell. It should be noted that if this subPDU is transmitted, it must appear at the very beginning of the RAR MAC PDU.

[0063] The second type of subPDU is used for the System Information (SI) request. It only contains a subheader for carrying the RAPID, and the specific structure is as Figure 2B shown. Among them, "E" is the extension field, which is used to indicate 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; "RAPID" is used to carry the RAPID.

[0064] The third type of subPDU is used to indicate RAPID with MAC RAR, which consists of a MAC subheader for carrying RAPID and a MAC RAR. The specific structure is as shown in Figure 2C Figure []. In the MAC RAR, "R" is a reserved bit; "TA command" is used to indicate the timing advance; "UL Grant" is used to indicate the resource scheduling information of the first PUSCH (i.e., Msg3) in the RAR; "TC-RNTI" is used to carry the TC-RNTI.

[0065] Among them, the 27 bits of "UL Grant" contain 6 fields:

[0066] Frequency hopping flag (1 bit): Used to indicate whether frequency hopping is enabled for the PUSCH;

[0067] PUSCH frequency domain resource allocation (14 bits): Used to indicate the frequency domain scheduling position of the PUSCH and the offset of frequency hopping (if frequency hopping is enabled);

[0068] PUSCH time domain resource allocation (4 bits): Used to indicate the time domain scheduling position of the PUSCH;

[0069] 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;

[0070] Transmit Power Control (TPC) command for the PUSCH (3 bits): Used to indicate the power step size parameter {-6, -4, -2, 0, 2, 4, 6, 8} dB;

[0071] Channel State Information (CSI) request (1 bit): Reserved bit. 9. RAR window (window)

[0072] It should be noted that the figure number in is missing in the original text. You can check and supplement it according to the actual situation.After the UE sends the preamble on the RO, it will listen for the PDCCH of the scheduling random access response message Msg2 / B in the RAR window. The starting position of the RAR window is the earliest control resource set (CORESET) for receiving the PDCCH after the last symbol of the timing when the PRACH is sent. The above PDCCH is configured by the type1-PDCCH common search space (CSS) set. The length of the RAR window is configured by RRC.

[0073] It should be noted that the CORESET is a set of physical resources in a specific area of the downlink resource grid, used to carry the PDCCH or DCI. The NR PDCCH is specifically designed to be sent in a configurable control resource set.

[0074] The uplink transmission method provided by the embodiments of this application can be applied to the scenario where the UE sends a PRACH to perform random access.

[0075] In the related art, for a network-side device that does not send a downlink synchronization reference signal (such as an SSB), when the UE sends a PARCH to perform random access to the network-side device, since the UE cannot determine the transmission beam and path loss of the PRACH by measuring the downlink synchronization reference signal. Thus, the UE cannot determine the beam information and transmission power when sending the PRACH, resulting in the UE being unable to correctly send the PRACH.

[0076] For the uplink transmission method provided by the embodiments of this application, for a network-side device that does not send a downlink synchronization reference signal (such as an SSB), when the UE sends a PARCH to perform random access to the network-side device, the UE can obtain relevant configuration information for uplink transmission, such as transmission resource information, transmission power-related information, and transmission beam information. Then, the UE can perform the transmission of the PRACH based on the above relevant configuration information. Thus, the UE can send the PRACH according to the relevant configuration information, and thus can correctly send the PRACH.

[0077] Next, in conjunction with the accompanying drawings, the uplink transmission method provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.

[0078] Figure 3 It is a schematic flowchart of the uplink transmission method provided by the embodiments of this application, as Figure 3 shown, the uplink transmission method may include the following steps S201 and step S202:

[0079] Step S201: The UE obtains the first information.

[0080] Wherein, the first information is the relevant configuration information for uplink transmission, and the first information includes at least one of the following: transmission resource information, transmission power-related information, and transmission beam information.

[0081] In some embodiments of the present application, the first information is pre-configured information or information configured by a network-side device.

[0082] In some embodiments of the present application, the network-side device may be a TRP. The serving cell where the UE camps may be configured with multiple TRPs, and at least one of the multiple TRPs can be a first TRP that can send downlink information. The UE can receive the relevant configuration information (i.e., the first information) for uplink transmission from the first TRP and perform uplink transmission based on the relevant configuration information.

[0083] Exemplarily, the serving cell of the UE includes TRP1, TRP2, and TRP3. TRP1 and TRP2 can receive data but do not allow data transmission, and TRP3 can transmit data (e.g., send data). After TRP3 sends the relevant configuration information for uplink transmission to the UE, the UE can receive the relevant configuration information for uplink transmission from TRP3 and perform uplink transmission according to the relevant configuration information.

[0084] It can be understood that the uplink transmission method provided by the embodiments of the present application can be applied to a multi-TRP scenario. In a multi-TRP scenario, the serving cell can perform resource scheduling for the UE from multiple TRPs, thereby providing better coverage and data rate.

[0085] In some embodiments of the present application, the above-mentioned transmission resource information includes at least one of time-domain resources and frequency-domain resources.

[0086] In some embodiments of the present application, the above-mentioned transmission 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).

[0087] In some embodiments, the beam information (i.e., the above-mentioned transmission beam information) may include at least one of the following: 1) whether to use different beams for transmission; 2) reference signals, antenna ports, antenna panel information, etc. for determining the beam direction.

[0088] In some embodiments, the UE can determine a first transmission resource for performing uplink transmission according to the above-mentioned transmission resource information. Exemplarily, when the first information includes transmission resource information, the UE can determine the transmission resource information as the first transmission resource.

[0089] Exemplarily, the UE may determine a 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 send uplink information on different ROs, for example, PRACH.

[0090] In some embodiments of the present application, the above transmission power-related information includes at least one of the following: transmission power, power offset value, path loss information.

[0091] In some embodiments, when the first information includes the transmission power, the UE may determine the transmission power as the transmission power for uplink transmission.

[0092] Exemplarily, if the network-side device configures the transmission power as the maximum transmit power minus X dB, the UE may determine the transmission power for uplink transmission as the maximum transmit power minus X dB, where X is greater than 0. For example, the X dB may be 3 dB.

[0093] In some embodiments, the above power offset value is the power offset value of the transmission power for sending the second uplink information compared to the transmission power for sending the first uplink information. Exemplarily, the above first uplink information may be a PRACH associated with the SSB initiated by the UE, or the above first uplink information is a PRACH associated with the 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.

[0094] In some embodiments, when the network-side device configures the power offset value of the transmission power for the second uplink information compared to the transmission power for the first uplink information, the UE may determine the transmission power for sending the second uplink information according to the transmission power for sending the first uplink information and the power offset value.

[0095] In some embodiments, when the first information includes transmission power-related information and the transmission power-related information includes a power offset value, the UE may determine a first transmission power for uplink transmission based on the power offset value.

[0096] Exemplarily, the UE may determine the sum of the transmission power of the first PRACH and the power offset value as the first transmission power. It can be understood that the first transmission power may be the transmission power of the second PRACH, expressed as: P(transmission power of the second PRACH) = P(transmission power of the first PRACH) + power offset value, where P(transmission power of the first PRACH) is the transmission power of the PRACH that successfully detected the RAR last time.

[0097] It can be understood that the above second uplink information may be the uplink information that the UE needs to send when currently performing uplink transmission.

[0098] 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.

[0099] Exemplarily, the UE may determine the sum of the target receive power of the UE, the reference path loss (i.e., path loss information), and the power offset value as the transmit power of the PRACH, expressed as the transmit power P of the PRACH = P (target receive power) + reference path loss + first power offset value.

[0100] It should be noted that the above target receive power is the maximum receive power when the UE receives a signal, and the above reference path loss may also be obtained based on measuring a reference signal for the reference path loss.

[0101] In some embodiments, the above first information further includes first indication information, and 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.

[0102] Exemplarily, the UE receives a signaling (such as DCI) from a network-side device, where the signaling triggers PRACH transmission, and the signaling includes 1-bit indication information, and the indication information indicates whether the power of the activated PRACH is to apply the power offset value, that is, whether to apply the power offset value when determining the transmit power of the PRACH.

[0103] In the embodiments of the present application, the network-side device may indicate whether the configured power offset value is effective. If it indicates that the power offset value is effective, the UE may determine the first transmit power for uplink transmission based on the power offset value.

[0104] Exemplarily, the network-side device may be a base station or a core network device.

[0105] In some embodiments of the present application, the above first information has an association relationship with the sounding reference signal SRS; or,

[0106] the above first information has an association relationship with the channel state information reference signal CSI-RS; or,

[0107] the above first information has an association relationship with the random access opportunity RO.

[0108] In some embodiments, the network-side device may configure the association relationship between the first information and the SRS, or configure the association relationship between the first information and the CSI-RS, or configure the association relationship between the first information and the 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.

[0109] Exemplarily, in the case where the UE sends the SRS, the UE may determine the transmission resource associated with the SRS as the transmission resource 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.

[0110] Exemplarily, in the case where the UE determines the RO for sending the PRACH, the UE may determine the transmission resource associated with the RO as the transmission resource 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.

[0111] Step S202: The UE performs uplink transmission based on the above first information.

[0112] In some embodiments of the present application, the UE may determine at least one of the transmission resource, transmission power, and transmission beam for performing uplink transmission based on the above first information, and perform uplink transmission according to at least one of the transmission resource, transmission power, and transmission beam.

[0113] It can be understood that performing uplink transmission means sending uplink information to the network-side device, that is, an uplink signal or an uplink channel.

[0114] In the uplink transmission method provided by the embodiments of the present application, the UE obtains first information, which is the relevant configuration information for uplink transmission, and 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 above 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 according to the above information, so that when the UE transmits uplink data to the network device, it can determine the transmission resource, transmission power, or transmission beam for performing the uplink transmission according to the relevant configuration information for uplink transmission, thereby correctly performing uplink transmission.

[0115] In some embodiments of the present application, the above first information includes transmission power-related information, and the transmission power-related information includes a power offset value; Exemplarily, the above step S202 may include the following steps S202a and S202b:

[0116] Step S202a: The UE determines a first transmission power according to the first power and the above power offset value.

[0117] Step S202b: The UE performs uplink transmission according to the above first transmission power.

[0118] Wherein, the above first power is the received power or the first transmission power of the UE, the above first transmission power is the transmission power of the UE for transmitting a first channel, and the above first channel is any one of the following: an uplink synchronization channel associated with a downlink synchronization signal, an uplink synchronization channel transmitted to a first network side device; the above first network side device is a network side device with downlink synchronization signal transmission.

[0119] It should be noted that the explanation of the above power offset value can be referred to the relevant description above, and will not be elaborated here.

[0120] In some embodiments, the above downlink synchronization signal may be an SSB.

[0121] In some embodiments, the above uplink synchronization channel may be a PRACH.

[0122] In some embodiments, the above first network side device may be a base station.

[0123] Exemplarily, taking the first channel as the PRACH associated with the SSB as an example, the UE may calculate the sum of the transmission power of the PRACH on which the RAR was successfully detected last time and the power offset value, and determine the sum of the transmission power of the PRACH and the power offset value as the first transmission power, and then use the first transmission power to transmit the PRACH.

[0124] In the embodiments of the present application, the UE may determine the transmission power of the PRACH to be currently transmitted based on the transmission power of the PRACH on which the RAR was successfully detected last time and the power offset value, so that the UE may determine the transmission power of the PRACH to be transmitted this time according to the transmission power of the PRACH successfully transmitted last time and the power offset value, thereby being able to accurately determine the transmission power of the PRACH.

[0125] In some embodiments of the present application, the above step S201 may be implemented by the following step S201a.

[0126] Step S201a: The UE receives a first message from a network side device.

[0127] Wherein, the above first message includes first information.

[0128] In some embodiments, the first message includes any one of the following: a Physical Downlink Control Channel (PDCCH) command, a Random Access Response (RAR) message, and system information.

[0129] In some embodiments, the PDCCH command may be a signaling sent by a network-side device for triggering a Physical Random Access Channel (PRACH).

[0130] In some embodiments, the RAR is a message sent by a network-side device for responding to Msg1 (or PRACH). Exemplarily, the RAR may be Msg2 or MsgB.

[0131] In some examples, taking the first message as the PDCCH command as an example, the network-side device sends a PDCCH command to the UE. The PDCCH command is used to trigger PRACH transmission. The PDCCH signaling includes at least one of the following information: power information for PRACH transmission, PRACH transmission beam information, PARCH transmission behavior information, and PRACH resource information. Exemplarily, the power information for PRACH transmission may include path loss information and power offset information; the PRACH transmission behavior information may include the PRACH transmission beam information; the PARCH transmission behavior information may include transmitting using one beam or multiple beams; the PRACH resource information may be the RO packet or RO window for transmitting the PRACH. The UE may determine information such as the transmission power, transmission resource, and transmission beam when transmitting the PRACH based on the above information in the PDCCH signaling.

[0132] In some examples, taking the first message as the RAR as an example, the network-side device sends an RAR message to the UE. The RAR message indicates the allocation of at least one uplink resource (e.g., uplink Physical Uplink Shared Channel (PUSCH) resource) for the UE to send Msg3. The RAR message includes at least one of the following information: at least one Timing Advance (TA) associated with at least one uplink resource, at least one power information associated with at least one uplink resource, and TA Group (TAG) information associated with at least one uplink resource. The UE may determine the uplink resource for subsequent Msg3 transmission based on the uplink resource from the network-side device, determine the transmission 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.

[0133] In the embodiments of the present application, the network side device may 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 the subsequent transmitted information based on the indication of the network side device. And since the relevant information sent by the network side device to the UE is multiplexed to indicate the relevant configuration, the addition of new radio signaling for indicating the UE uplink transmission related configuration is avoided, thereby improving the utilization rate of radio resources.

[0134] In some embodiments of the present application, the above uplink transmission method may include the following step S203:

[0135] Step S203: The UE receives second indication information from the network side device.

[0136] Wherein, the above second indication information is used to indicate that the first information is carried in the first message.

[0137] In some embodiments, the network side device may send 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 may 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.

[0138] Exemplarily, taking the first message as the RAR message, the network side device may send indication information to indicate that the relevant configuration information of the uplink transmission is carried in the RAR message. After receiving the RAR message sent by the network side device, the UE parses the RAR message to obtain the relevant configuration information of the uplink transmission.

[0139] For example, the UE receives an RRC configuration, and this RRC configuration indicates the number of first messages included in the RAR.

[0140] It should be noted that the above step S203 may be executed before the above step S201, or the above step S203 may be executed simultaneously with the above step S201, or the above step S203 may be executed after the above step S201.

[0141] In the embodiments of the present application, the network side device may 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 indication of the network side device, thereby further ensuring that the UE obtains the relevant configuration information of the uplink transmission.

[0142] In some embodiments of the present application, the above step S202 may include the following step S202c:

[0143] Step S202c: The UE performs uplink transmission of the second message based on the above first information.

[0144] It can be understood that the uplink transmission of the second message by the UE means that the UE sends the second message to the network device.

[0145] Wherein, the second message includes any one of the following: Physical Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Msg1, Msg3.

[0146] Exemplarily, taking the second message as PRACH as an example, after the UE obtains the relevant configuration information for uplink transmission, it can determine the resources, beams, and transmission power for uplink transmission according to the above relevant configuration information, and use the above transmission power to send PRACH through the resources for uplink transmission using the above beam.

[0147] In the embodiments of the present application, the UE can determine information such as resources, beams, or transmission power when sending uplink information such as PRACH, PUCCH, PUSCH, etc. according to the relevant configuration information for uplink transmission, without relying on downlink synchronization signals to determine, so that the UE can correctly send uplink information even when the network device does not send downlink synchronization signals.

[0148] In some embodiments of the present application, the above first information includes transmission resource information; Exemplarily, the above step S202 may include the following step S202d:

[0149] Step S202d: The UE selects an RO based on the above transmission resource information and performs uplink transmission using the selected RO.

[0150] In some embodiments, when the transmission resource information includes at least one transmission resource, the UE can determine the resource for uplink transmission from the at least one transmission resource.

[0151] In some embodiments, the resource for uplink transmission can be indicated by the network device, or the resource for uplink transmission is predefined by the protocol.

[0152] Exemplarily, when the transmission resources include RO#0, RO#1, RO#2, and RO#3, if the network device indicates uplink transmission on RO#2, the UE can select RO#2 from the above multiple ROs to send uplink information.

[0153] Exemplarily, when the transmission resources include RO#0, RO#1, RO#2, and RO#3, if the protocol predefines uplink transmission on the first RO, the UE can select RO#0 from the above multiple ROs to send uplink information.

[0154] In an embodiment of the present application, when a UE performs uplink transmission, it can obtain transmission resource information for the uplink transmission and select uplink resources according to the transmission resource information, so that the UE can determine the transmission resources without relying on downlink synchronization signals, and thus can correctly transmit uplink information even when the network-side device does not send downlink synchronization signals.
