Description

Information transmission methods and devices, terminal equipment, network equipment, chips, storage media, and software products Technical Field

[0001] This application relates to the field of mobile communication technology, specifically to an information transmission method and apparatus, terminal equipment, network equipment, chip, storage medium, and computer program product. Background Technology

[0002] Network devices periodically transmit Synchronization Signal / PBCH Block (SSB) bursts using beam scanning. This means that network devices can transmit different SSBs on different beams using time-division multiplexing. Correspondingly, terminal devices can measure the SSBs and initiate a random access procedure based on the beam corresponding to the SSB with the best measurement result.

[0003] In practical applications, the resources of the Physical Random Access Channel (PRACH) sent by the terminal device are associated with the SSB. If the network device successfully receives the PRACH, it obtains the downlink beam information of the terminal device based on the PRACH resources, and then uses this beam information for subsequent communication, such as sending Random Access Message 2 (Msg2), Random Access Message 4 (Msg4), or Random Access Message B (MsgB). However, establishing the association between the SSB and the PRACH resources for random access incurs significant PRACH resource overhead.

[0045] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0046] 1. Random Access

[0047] Terminal devices can obtain the Master Information Block (MIB) sent by network devices by searching the Synchronization Signal and Physical Broadcast Channel (SSB). Then, based on the MIB, the terminal device can obtain the time-domain and frequency-domain resources of the Control Resource Set (CORESET). This allows the terminal device to detect the Downlink Control Information (DCI) of the System Information Block (SIB) on the time-domain and frequency-domain resources of the CORESET, and receive SIB1 at the time-frequency position indicated by the DCI. In this way, the terminal device can obtain information such as the initial uplink bandwidth part (Initial UL BWP), the initial downlink bandwidth part (Initial DL BWP), the random access preamble list, and the random access occasion (RO) list indicated in SIB1.

[0048] Furthermore, the terminal device can perform a random access procedure through the PRACH resource indicated by SIB1.

[0049] Referring to the four-step random access process diagram shown in Figure 2, the four-step random access process includes the following steps:

[0050] Step 1: The terminal device sends a preamble sequence to the network device via PRACH. This preamble sequence can also be called Message 1 (Msg1) of the random access procedure. The preamble notifies the network device of a random access request and enables the network device to estimate the transmission delay between the terminal device and the network device. This allows the network device to calibrate the uplink timing of the terminal device and inform the terminal device of the calibration information via a Timing Advance (TA) command.

[0051] Step 2: The network device sends a Random Access Response (RAR) to the terminal device. The RAR, also known as Message 2 (Msg2) of the random access procedure, may contain the identifier of the received preamble sequence, the TA (Temporary Access Response) amount, the Uplink Grant (UL Grant), and the Temporary Cell Radio Network Temporary Identifier (TC-RNTI). The TA is used by the terminal device for uplink timing adjustments to ensure uplink synchronization. The UL Grant can indicate the resource location of the Physical Uplink Shared Channel (PUSCH) used to transmit Message 3 (Msg3).

[0052] Step 3: The terminal device sends Msg3 to the network device via the PUSCH indicated by Msg2.

[0053] Step 4: The network device receives Msg3 and sends a contention resolution message to the successfully connected terminal device. This contention resolution message can also be called message 4 (Msg4). The DCI used for scheduling Msg4 is scrambled with the TC-RNTI carried in the RAR. The network device can use Msg4 to perform RRC configuration on the terminal device. The TC-RNTI scrambled DCI carries indication information for the Physical Uplink Control Channel (PUCCH) used by the terminal to provide Acknowledgment (ACK) / Negative Acknowledgment (NACK).

[0054] Step 5: If the terminal device correctly receives Msg4, it sends an ACK to the network device via PUCCH according to the indication information in the DCI. If it fails to receive message 4 correctly, it sends a NACK to the network device via PUCCH. If the network device does not receive an ACK / NACK within a time window, it can retransmit Msg4.

[0055] Referring to the two-step random access procedure diagram shown in Figure 3, the two-step random access process includes the following steps:

[0056] Step 1: The terminal device sends MsgA, which includes a preamble and a MsgA PUSCH that does not overlap with the preamble in terms of time-domain resources. MsgA is similar to a combination of Msg1 and Msg3 in the traditional four-step process. The preamble is used to notify the network device of a random access request, and the MsgA PUSCH may carry a User Equipment ID (UE ID) for conflict resolution in subsequent response messages. In addition, the data signal may also contain information such as an RRC connection request, a Buffer Status Report (BSR), and data payload.

[0057] Step 2: When the network device receives MsgA, it will send RAR to the terminal device. RAR is also called Message B (MsgB) of the two-step random access procedure. RAR may contain more information, such as timing advance, uplink authorization, and possible contention resolution instructions.

[0058] 2. SSB

[0059] A single SSB can include a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH) distributed across four consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols. Referring to Figure 4, which illustrates the SSB timing structure, an SSB burst set period includes multiple SSBs (e.g., eight SSBs), and different SSBs can correspond to different beam directions. NR supports SSB burst set periods of 5 milliseconds (ms), 10 ms, 20 ms, etc.

[0060] A key feature of NR cells is their support for downlink multi-beaming. Before communication between network devices and terminal devices, the network devices need to know the beam the terminal device is in in order to set the appropriate beam direction during subsequent data transmission. Since the PRACH in the random access procedure is the first message sent by the terminal device to the network, and the network device needs to know the beam information of the terminal device when sending Msg2 or MsgB, the function of reporting the beam where the terminal device is located is naturally carried out by the PRACH.

[0061] Since the random access preamble carried by PRACH is a sequence signal, it cannot explicitly carry information. However, it can implicitly carry beam information using the time-frequency resources occupied by the preamble or different preamble sequences. Therefore, the NR system needs to establish a mapping relationship between SSB and RO.

[0062] Before a terminal device initiates a PRACH, it can measure and evaluate the signal quality of the cell and the signal strength of each SSB within the cell. When initiating a PRACH, the terminal device can send a preamble on the RO corresponding to the SSB with the strongest or relatively strong signal. If the network device successfully receives the preamble, it obtains the downlink beam information of the terminal device based on the RO where the preamble is located, and then uses this beam information for subsequent communication, such as transmitting Msg2 and Msg4.

[0063] It should be understood that there are several possible mapping relationships between SSBs and ROs: 1) one-to-one mapping; 2) many-to-one mapping; 3) one-to-many mapping. Considering the need to support diverse scenarios, all three ratios are supported in the NR standard. For example, in scenarios with fewer users, multiple SSBs can correspond to the same RO to save PRACH resources; in scenarios with more users, one SSB can correspond to multiple ROs to provide sufficient PRACH capacity.

[0064] In practical applications, NR systems contain multiple actual SSBs, multiple configured RO resources, and preamble resources. Both network devices and terminal devices need to know which RO resources and preamble resources correspond to each SSB. Based on this, the standard specifies the rules for the mapping order of SSBs with ROs and preamble resources, as follows:

[0065] First, in a PRACH occasion, the order of the preamble indexes is increasing;

[0066] Second, the frequency resource index order for frequency reuse PRACH occasions is incremental;

[0067] Third, the order of time-domain resource indices for time-domain multiplexing PRACH occasions within PRACH time slots is ascending;

[0068] Fourth, the order of the PRACH slot index is ascending.

[0069] Understandably, network devices periodically send SSB burst sets in a beam scanning manner, that is, they send different SSBs on different beams in a time-division multiplexing manner. The terminal device measures the SSBs and selects the strongest beam to initiate a random access procedure.

[0070] In practical applications, the resources (ROs) used by terminal devices to transmit PRACH are associated with their SSBs. If the network successfully receives the preamble corresponding to the PRACH, it obtains the downlink beam information of the terminal device based on the RO where the preamble is located, and then uses this beam information for subsequent communication, such as sending Msg2, Msg4, or MsgB. Establishing the association between SSBs and ROs for random access incurs significant PRACH resource overhead.

[0071] Based on this, embodiments of this application provide an information method in which a terminal device sends first information, the first information including index information of a first downlink reference signal; the first information is associated with a random access first message sent by the terminal device. That is, the first information sent by the terminal device to the network device can explicitly indicate the first downlink reference signal associated with the random access first message. In this way, the PRACH resources used by the terminal device to send the random access first message can be debonded from the downlink reference signal, thereby reducing the overhead of PRACH resources.

[0072] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0073] Figure 5 illustrates an information transmission method provided in an embodiment of this application, which may include the following steps:

[0074] S510, the terminal device sends first information, and correspondingly, the network device receives the first information; wherein, the first information includes index information of the first downlink reference signal; the first information is associated with the random access first message sent by the terminal device.

[0075] It should be noted that the downlink reference signal mentioned in the embodiments of this application can be either SSB or Channel State Information Reference Signal (CSI-RS), and the embodiments of this application do not impose any restrictions on it.

[0076] It should be understood that the first downlink reference signal can be one or more downlink reference signals from the downlink reference signal set (SSB burst set, or CSI-RS set), where different downlink reference signals correspond to different beam directions. Specifically, the first downlink reference signal can be one or more downlink reference signals from the downlink reference signal set whose measurement results satisfy certain conditions. These conditions can be either optimal measurement results or measurement results exceeding a threshold.

[0077] Specifically, the network device can periodically send a set of reference signals in a beam scanning manner. Correspondingly, the terminal device can measure the downlink reference signals sent by the network device and select one or more downlink reference signals whose measurement results meet the conditions to obtain the first downlink reference signal.

[0078] In this embodiment of the application, the terminal device can explicitly indicate a first downlink reference signal through first information. For example, the first information may include index information of the first reference signal, and the terminal device explicitly indicates the first reference signal through the index information of the first reference signal.

[0079] It should be noted that the index information can be replaced with other information that can uniquely identify the reference signal, such as identification information, identity information, etc. In other words, other information that can uniquely identify the reference signal is also within the protection scope of this application's embodiments, and this application's embodiments do not impose any restrictions on it.

[0080] It should also be noted that the first information is related to the random access procedure of the terminal device, or in other words, the first information can be used in the random access procedure of the terminal device. Specifically, the first information can be associated with the first random access message.

[0081] In some embodiments, the first random access message may include a four-step random access message 1 (Msg1) and / or a two-step random access message A (MsgA).

[0082] In some embodiments, the first information is associated with the random access first message (Msg1 and / or MsgA). This can be understood as the index information of the first reference signal carried by the first information being associated with Msg1 and / or MsgA, or in other words, the first reference signal indicated by the first information being associated with Msg1 and / or MsgA. The first reference signal can indicate the beam direction corresponding to Msg1 and / or MsgA transmitted by the terminal device.

[0083] Understandably, after receiving the first information, the network device can obtain the downlink beam information of the terminal device based on the first downlink reference signal indicated by the first information, and then conduct subsequent communication based on the beam information, such as sending Msg2, Msg4 or MsgB to the terminal device based on the beam information.

[0084] It should be noted that in the embodiments of this application, the beam can also be called a spatial filter, and the two are equivalent or interchangeable.

[0085] In the information transmission method provided in the embodiments of this application, the first information can explicitly indicate the first downlink reference signal associated with Msg1 and / or MsgA. In this way, the PRACH resources of the terminal device transmitting Msg1 and / or MsgA can be unbound from the downlink reference signal, thereby reducing the overhead of PRACH resources.

[0086] In some embodiments, the first information may also include the measurement results of the first downlink reference signal.

[0087] It should be noted that the measurement results of the first downlink reference signal may include the reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal to interference plus noise ratio (SINR), etc., and the embodiments of this application do not limit this.

[0088] Understandably, the terminal device uses the first information to indicate the measurement result obtained by the terminal device based on the first reference signal. In this way, the network device can determine the transmit power of the downlink channel (e.g., Msg2, Msg4, or MsgB) based on the measurement result of the first downlink reference signal.

[0089] It should be noted that there are several ways for a terminal device to send the first information. In one implementation, the terminal device can carry the first information via MsgA. In another implementation, the terminal device can send the first information on different transmission resources, such as sending Msg1 or MsgA. These two implementations will be described below.

[0090] Method #A: When the first message of random access is MsgA, the first information is carried in MsgA.

[0091] It should be noted that method #A can be applied to a two-step random access procedure.

[0092] It should be understood that for a two-step random access procedure, MsgA may include a preamble and a PUSCH that does not overlap with the temporal resources of the preamble. The terminal device may add first information to the PUSCH of MsgA, explicitly indicating a first reference signal through the first information, so that the network device may transmit MsgB based on the first reference signal indicated by the first information.

[0093] For example, refer to the Information Elements (IEs) of MsgA PUSCH shown in Table 1. Add one or more of the following fields to MsgA PUSCH: SSB Index Information (SSB-Index), SSB Measurement Results (ssb-RSRP), CSI-RS Index Information (csi-RS-Index), and CSI-RS Measurement Results (csi-rs-rsrp).

[0094] Table 1

[0095] In this embodiment, the first information can explicitly indicate the first downlink reference signal associated with MsgA, so that the PRACH resources of the terminal device transmitting MsgA can be debonded from the downlink reference signal, thereby reducing the overhead of PRACH resources.

[0096] Method #B: The first information is transmitted on the first transmission resource; the first transmission resource and the second transmission resource do not overlap in the time domain, and the second transmission resource is used to transmit the random access first message.

[0097] It should be noted that method #B can be applied to either a four-step random access procedure or a two-step random access procedure.

[0098] In mode #B, the terminal device can send the first information on the first transmission resource and send Msg1 or MsgA on the second transmission resource.

[0099] It should be noted that the time domain position of the first transmission resource may be before or after the time domain position of the second transmission resource, and this application embodiment does not impose any restrictions on this.

[0100] It should also be noted that the second transmission resource can be understood as RO or random access PRACH resource; the three are equivalent or interchangeable.

[0101] In some embodiments, the first transmission resource (including time-domain resources and / or frequency-domain resources) can be determined based on predefined information or second configuration information sent by the network device. That is, the first transmission resource can be a predefined transmission resource or a transmission resource configured by the network device.

[0102] It should be noted that the second configuration information can be system messages, such as MIB, SIB, etc., and this application embodiment does not limit this.

[0103] In some embodiments, the predefined information or the second configuration information sent by the network device includes one or more of the following:

[0104] The temporal location of the first transmission resource;

[0105] The time domain period of the first transmission resource;

[0106] The first time window for occupancy of transmission resources;

[0107] The symbol position occupied by the first transmission resource;

[0108] The starting symbol of the first transmission resource;

[0109] The number of symbols occupied by the first transmission resource;

[0110] The frequency domain location of the first transmission resource;

[0111] The location of the resource block (RB) occupied by the first transmission resource;

[0112] The location of the starting RB of the first transmission resource;

[0113] The number of RBs occupied by the first transmission resource;

[0114] The first transmission resource occupied by RE.

[0115] For example, the predefined information or the second configuration information may include the time window of the first transmission resource, the starting symbol position K, and the number of symbols occupied M; the terminal device may send the first information to the network device on the M consecutive symbols starting from the Kth symbol within the time window after the first downlink reference signal (e.g., SSB).

[0116] In other embodiments, the first transmission resource can be determined based on Msg1 or MsgA associated with the first information.

[0117] In this embodiment of the application, the association between the first information and the random access first message includes one or more of the following:

[0118] The first transmission resource is associated with the second transmission resource;

[0119] The first transmission resource is associated with the preamble sequence of the first random access message;

[0120] The first transmission resource is associated with the sequence group corresponding to the preamble sequence of the first random access message.

[0121] Understandably, in one implementation, the first transmission resource is associated with the second transmission resource, that is, the terminal device can determine the first transmission resource based on the second transmission resource that sends Msg1 or MsgA.

[0122] For example, the association between the first transmission resource and the second transmission resource includes one or more of the following:

[0123] The time slot position of the first transmission resource is offset from the time slot position of the second transmission resource by a first offset.

[0124] The symbol position of the first transmission resource is separated from the symbol position of the second transmission resource by a second offset;

[0125] The frequency domain location of the first transmission resource is the same as that of the second transmission resource;

[0126] The frequency domain position of the first transmission resource is offset from the frequency domain position of the second transmission resource by a third offset.

[0127] The RB position of the first transmission resource is offset by a fourth distance from the RB position of the second transmission resource;

[0128] The RE position of the first transmission resource is offset by a fifth distance from the RE position of the second transmission resource.

[0129] It should be noted that the first offset can be an offset between the starting time slot position of the first transmission resource and the starting time slot position of the second transmission resource (i.e., RO), or an offset between the starting time slot position of the first transmission resource and the ending time slot position of the second transmission resource, or an offset between the ending time slot position of the first transmission resource and the starting time slot position of the second transmission resource, or an offset between the ending time slot position of the first transmission resource and the ending time slot position of the second transmission resource. This application embodiment does not impose any limitations on this. Furthermore, the granularity of the first offset can be a time slot or a symbol, which is also not limited in this application embodiment.

[0130] It should be noted that the second offset can be the offset between the start symbol position of the first transmission resource and the start symbol position of the second transmission resource, or the offset between the start symbol position of the first transmission resource and the end symbol position of the second transmission resource, or the offset between the end symbol position of the first transmission resource and the start symbol position of the second transmission resource, or the offset between the end symbol position of the first transmission resource and the end symbol position of the second transmission resource. This application embodiment does not impose any limitation on this. The granularity of the second offset can be a symbol.

[0131] It should be noted that the frequency domain position of the first transmission resource is the same as that of the second transmission resource. This can be understood as the starting frequency domain position and the number of RBs or REs occupied by the first and second transmission resources being the same. In other words, the frequency domain positions of the first and second transmission resources coincide.

[0132] It should also be noted that the third offset can be an offset between the starting frequency domain position of the first transmission resource and the starting frequency domain position of the second transmission resource, or an offset between the starting frequency domain position of the first transmission resource and the ending frequency domain position of the second transmission resource, or an offset between the ending frequency domain position of the first transmission resource and the starting frequency domain position of the second transmission resource, or an offset between the ending frequency domain position of the first transmission resource and the ending frequency domain position of the second transmission resource. This application embodiment does not impose any limitations on this. The starting frequency domain position of the second transmission resource is either the starting frequency domain position corresponding to the first RO in the frequency domain, or the starting frequency domain resource position corresponding to the RO where PRACH is located. This application embodiment does not impose any limitations on this.

[0133] It should also be noted that the fourth offset can be the offset between the starting RB position of the first transmission resource and the starting RB position of the second transmission resource, or the offset between the starting RB position of the first transmission resource and the ending RB position of the second transmission resource, or the offset between the ending RB position of the first transmission resource and the starting RB position of the second transmission resource, or the offset between the ending RB position of the first transmission resource and the ending RB position of the second transmission resource. This application embodiment does not impose any limitations on this. The granularity of the fourth offset can be RB or RE, and this application embodiment does not impose any limitations on this.

[0134] It should also be noted that the fifth offset can be the offset between the starting RE position of the first transmission resource and the starting RE position of the second transmission resource, or the offset between the starting RE position of the first transmission resource and the ending RE position of the second transmission resource, or the offset between the ending RE position of the first transmission resource and the starting RE position of the second transmission resource, or the offset between the ending RE position of the first transmission resource and the ending RE position of the second transmission resource. This application embodiment does not limit this. The granularity of the fifth offset can be RE, and this application embodiment does not limit this.

[0135] In one example, the time slot position and symbol position of the first transmission resource are associated with the second transmission resource. The terminal device can determine the first transmission resource by combining these two factors. That is, the terminal device can determine the time slot position of the first transmission resource based on the time slot position and the first offset of the second transmission resource, and determine the symbol position of the first transmission resource based on the symbol position and the second offset of the second transmission resource, thus obtaining the final resource position of the first transmission resource (in this example, the frequency domain position of the first transmission resource can be the same as the frequency domain position of the second transmission resource).

[0136] In one example: the time slot position, symbol position, and frequency domain position of the first transmission resource are associated with the second transmission resource. The terminal device can determine the first transmission resource by combining these three items. That is, the terminal device can determine the time slot position of the first transmission resource based on the time slot position and first offset of the second transmission resource; it can determine the symbol position of the first transmission resource based on the symbol position and second offset of the second transmission resource, thus obtaining the time domain position of the first transmission resource. Furthermore, the terminal device can determine the frequency domain position of the first transmission resource based on the frequency domain position and third offset of the second transmission resource. In this way, the terminal device can determine the final resource position of the first transmission resource.

[0137] Understandably, the association between the first transmission resource and the second transmission resource can be determined through predefined information or first configuration information sent by the network device. The predefined information or first configuration information may include one or more of the offsets from the first offset to the fifth offset.

[0138] It should be noted that the first configuration information can be either MIB or SIB, and this application embodiment does not limit it.

[0139] In another implementation, the first transmission resource can be associated with a preamble of Msg1 or MsgA. That is, the terminal device can determine the first transmission resource based on the preamble of Msg1 or MsgA sent.

[0140] Understandably, a preamble can be associated with a first transmission resource, and different preambles can be associated with different first transmission resources. After receiving a preamble sent by a terminal device, the network device can receive the first information sent by the terminal device on the first transmission resource associated with that preamble. The terminal device sends the first information according to the association relationship, and correspondingly, the network device can detect the first information according to the association relationship without signaling indication of the first transmission resource of the first information.

[0141] It should be noted that the association between the first transmission resource and the preamble can be determined based on predefined information or first configuration information sent by the network device. The first configuration information can be a MIB or a SIB; this embodiment does not impose any limitations on this.

[0142] In another implementation, the first transmission resource can be associated with the sequence group corresponding to the preamble. That is, the terminal device can determine the first transmission resource based on the sequence group corresponding to the preamble of the transmitted Msg1 or MsgA.

[0143] Understandably, different preamble sequence groups correspond to different first transmission resources. After receiving the preamble sent by the terminal device, the network device can receive the first information on the first transmission resource associated with the sequence group corresponding to the preamble. The terminal device sends the first information according to the association relationship, and correspondingly, the network device can detect the first information according to the association relationship without signaling indication of the first transmission resource for the first information.

[0144] It should be noted that the association between the first transmission resource and the sequence group corresponding to the preamble can be determined based on predefined information or first configuration information sent by the network device. The first configuration information can be a MIB or a SIB; this embodiment does not impose any limitations on this.

[0145] In mode #B, the first information can be transmitted in the first uplink channel, and the first transmission resource is the transmission resource of the first uplink channel. It should be noted that the first uplink channel can be either PUSCH or PUCCH; this embodiment does not impose any limitation on this.

[0146] In some embodiments, the transmission parameters of the first uplink channel include one or more of the following:

[0147] The first modulation and coding scheme (MCS);

[0148] Enable or disable transport precoding;

[0149] First transmission port.

[0150] For example, the first transmission port may be a PUSCH port, such as one or more of ports 1 to 4.

[0151] It should be noted that one or more of the above transmission parameters can be determined based on predefined information or third configuration information sent by the network device. The third configuration information can be higher-layer signaling, such as non-intrusive layer signaling; it can also be a MIB or SIB, and this application embodiment does not impose any limitations on this.

[0152] It should also be noted that the third configuration information may be the same as or different from the first or second configuration information mentioned above, and this application embodiment does not impose any restrictions on this.

[0153] In some embodiments, the configuration of the demodulation reference signal (DMRS) of the first uplink channel includes one or more of the following:

[0154] Location information of DMRS symbols;

[0155] DMRS symbol count;

[0156] DMRS code division multiplexing packets;

[0157] Types of DMRS.

[0158] It should be noted that the configuration of the DMRS described above can be determined based on predefined information or fourth configuration information sent by the network configuration device. The fourth configuration information can be higher-layer signaling, such as non-intrusive layer signaling; it can also be a MIB or SIB, and this embodiment does not impose any limitations on this.

[0159] It should also be noted that the fourth configuration information is the same as the first, second, or third configuration information. The fourth configuration information may also be different from the first, second, and third configuration information. This application embodiment does not limit this.

[0160] [Correction 26.08.2024 based on Rule 91] In some embodiments, the transmission power of the first uplink channel needs to be defined. The transmission power of the first uplink channel can be determined based on formula (1). P PUSCH =min{Pcmax,Po+alpha*PL+f(i,l)} (1)

[0161] [Corrected according to detailed rule 91 26.08.2024] Wherein, P PUSCH Pcmax is the transmission power of the first uplink channel, Po is the maximum transmit power supported by the terminal device, alpha is the path loss factor, PL is the path loss, and f(i,l) is the closed-loop power adjustment parameter.

[0162] [Correction based on Rule 91 26.08.2024] It is understood that the transmission power of the first uplink channel can be the minimum of the maximum transmit power of the terminal device and the first power; wherein the first power is determined based on the target receive power Po, the path loss factor alpha, the path loss PL and the closed-loop power adjustment parameter f(i,l).

[0163] [Corrected according to Rule 91, August 26, 2024] It should be noted that the target received power Po in formula (1) can be determined based on predefined information or the fifth configuration information sent by the network device. For example, the predefined information or the fifth configuration information can configure the index information of Po, and the terminal device can determine Po based on the index information.

[0164] [Correction based on Rule 91, 26.08.2024] It should also be noted that the fifth configuration information is the same as one or more of the first to fourth configuration information, and the fifth configuration information may also be different from the first to fourth configuration information. This application embodiment does not limit this.

[0165] [Correction based on Rule 91, August 26, 2024] In some embodiments, the fifth configuration information is also used to configure the relevant transmission parameters of the random access first message. It is understood that the fifth configuration information may be PRACH configuration information. That is, Po can configure it through PRACH-related configuration information.

[0166] [Correction 26.08.2024 according to Rule 91] In some embodiments, the path loss PL in formula (1) may be determined based on the measurement of a second downlink reference signal; the second downlink reference signal includes one or more of the following:

[0167] [Correction based on Rule 91, August 26, 2024] Type 1 downlink reference signal; Type 1 downlink reference signal is used to instruct the terminal device to send first information;

[0168] [Correction based on Rule 91, August 26, 2024] Downlink reference signal corresponding to the system message obtained by the terminal device;

[0169] [Correction 26.08.2024 according to Rule 91] Downlink reference signal with the same resource index as the first downlink reference signal.

[0170] [Corrected according to Rule 91, August 26, 2024] It should be noted that network devices can send different types of downlink reference signals to instruct terminal devices to use different random access methods for random access. In the embodiments of this application, the first type of downlink reference signal can be associated with the method provided in the embodiments of this application. It can be understood that when the terminal device detects the first type of downlink reference signal, it can perform random access by using the method provided in the embodiments of this application, that is, by sending the first information to explicitly instruct the downlink reference signal corresponding to the first random access message.

[0171] [Correction based on Rule 91 26.08.2024] Wherein, the downlink reference signal of the first type may be different from the traditional downlink reference signal. For example, the downlink reference signal of the first type may be a transmission mode applied to the centimeter wave or millimeter wave frequency band, which is different from the transmission mode of the downlink reference signal of the existing FR1 and FR2 frequency bands.

[0172] [Revised according to Rule 91, 26.08.2024] In one embodiment, PL in formula (1) may be determined based on the measurement results of a first type of downlink reference signal detected by the terminal device.

[0173] [Correction 26.08.2024 according to Rule 91] In another embodiment, PL in formula (1) can be determined based on the measurement results of SSB of MIB or SIB obtained by the terminal device.

[0174] [Correction 26.08.2024 according to Rule 91] In another embodiment, the reference signal used to determine PL in formula (1) can be determined by the measurement result of a first reference signal associated with Msg1 or MsgA.

[0175] [Correction based on Rule 91, August 26, 2024] It is understood that the terminal device can determine the transmission power of the first uplink channel based on the above method, and then send the first information to the network device based on the transmission power, so that the network device can receive the first information and thus carry out the subsequent communication process.

[0176] [Correction 26.08.2024 according to Rule 91] In some embodiments, the power priority of the first uplink channel is the same as the power priority of the random access first message, or the power priority of the first uplink channel is lower than the power priority of the random access first message.

[0177] [Corrected according to Rule 91 26.08.2024] That is to say, the power priority of the first uplink channel carrying the first information is not higher than the power priority of Msg1 or MsgA associated with the first information.

[0178] [Correction based on Rule 91, August 26, 2024] For example, the following channels are arranged in descending order of power priority:

[0179] [Corrected according to Rule 91 26.08.2024] PRACH transmitted on the Primary Cell (PCell), the first uplink channel transmitted on the PCell; it should be understood that the power priority of the first uplink channel transmitted on the PCell can be the same as the power priority of the PRACH transmitted on the PCell, or the power priority of the first uplink channel transmitted on the PCell can be less than the power priority of the PRACH transmitted on the PCell.

[0180] [Corrected according to Rule 91 26.08.2024] PUSCH or PUCCH with higher priority;

[0181] [Corrected according to Rule 91 26.08.2024] PUSCH or PUCCH with low priority;

[0182] [Corrected according to Rule 91 26.08.2024] SRS transmission, PRACH transmitted on a non-PCell cell, first uplink channel transmitted on a non-PCell cell; it should be understood that the power priority of the first uplink channel transmitted on a PCell may be the same as the power priority of the PRACH transmitted on the PCell, or the power priority of the first uplink channel transmitted on the PCell may be less than the power priority of the PRACH transmitted on the PCell.

[0183] [Corrected according to Rule 91, August 26, 2024] It should be noted that a low-priority PUSCH or PUCCH may include one or more of the following (arranged in descending order of power priority):

[0184] [Correction 26.08.2024 according to Rule 91] PUCCH transmission with HARQ-ACK information and / or SR and / or LRR, or PUSCH transmission with HARQ-ACK information with priority index;

[0185] [Correction 26.08.2024 based on Rule 91] PUCCH transmission with CSI or PUSCH transmission with CSI;

[0186] [Correction 26.08.2024 according to Rule 91] PUCCH transmission without HARQ-ACK information or CSI, or PUSCH transmission of a two-step random access procedure, or first uplink channel transmission.

[0187] [Correction based on Rule 91, August 26, 2024] It is understood that the terminal device can send a random access first message and a first uplink channel carrying first information based on the above power priority. In this way, the transmission priority of the first uplink channel can be clearly defined, ensuring that important information can be sent first.

[0188] [Correction based on Rule 91, 26.08.2024] It should be noted that the terminal device can access the network using the traditional random access method, or it can access the network by sending first information and a random access first message according to the method provided in the embodiments of this application.

[0189] [Correction 26.08.2024 based on Rule 91] In some embodiments, the terminal device may determine whether to send first information for random access according to certain rules.

[0190] [Correction 26.08.2024 according to Rule 91] In one embodiment, when the terminal device detects a downlink reference signal of the first type, it is determined to send the first information.

[0191] [Corrected according to Rule 91, August 26, 2024] It is understood that network devices can send different types of downlink reference signals to instruct terminal devices to use different random access methods for random access. In the embodiments of this application, the first type of downlink reference signal can be associated with the method provided in the embodiments of this application. It is understood that when the terminal device detects the first type of downlink reference signal, it can perform random access by using the method provided in the embodiments of this application, that is, by sending the downlink reference signal corresponding to the first message to explicitly instruct random access.

[0192] [Correction based on Rule 91, August 26, 2024] It should be noted that the first type of downlink reference signal may be different from the traditional downlink reference signal. For example, the first type of downlink reference signal may be a transmission mode applied to the centimeter wave or millimeter wave frequency band, which is different from the transmission mode of the downlink reference signal in the existing FR1 and FR2 frequency bands.

[0193] [Corrected according to Rule 91, August 26, 2024] In another embodiment, the network device can configure the terminal device to perform random access using the method provided in the embodiments of this application through the sixth configuration information, that is, to perform random access by sending the first information to explicitly indicate the downlink reference signal corresponding to the random access first message. Accordingly, the terminal device determines to send the first information based on the sixth configuration information sent by the network device.

[0194] [Correction based on Rule 91, August 26, 2024] It should be understood that terminal devices can use conventional random access methods or the methods provided in the embodiments of this application for random access. For network devices, it is necessary to distinguish which random access method the terminal device is using. Specifically, for terminal devices using the methods of the embodiments of this application for random access, the network device needs to receive first information on the first transmission resource or obtain the first information in MsgA. Therefore, it is particularly important for the terminal device to indicate whether to use the methods provided in the embodiments of this application for random access.

[0195] [Corrected according to Rule 91, August 26, 2024] In this embodiment of the application, the terminal device can indicate the random access method to be used through the first random access message. That is, the first random access message can indicate whether the terminal device should send the first information.

[0196] [Correction 26.08.2024 based on Rule 91] In one embodiment, the random access first message adopts a first preamble sequence; the first preamble sequence instructs the terminal device to send the first information.

[0197] [Correction based on Rule 91, August 26, 2024] It is understood that the first preamble sequence can be a new sequence, different from the existing preamble sequences. That is, a new preamble sequence can be defined to instruct the terminal device to perform random access by sending the first information.

[0198] [Correction 26.08.2024 based on Rule 91] In another embodiment, the random access first message adopts a preamble sequence with an index value of a first value, the first value instructing the terminal device to send the first information.

[0199] [Corrected according to Rule 91, August 26, 2024] That is to say, the type of random access method used by a terminal device can be distinguished by different preamble index values ​​(preamble ID). When the first random access message sent by the terminal device uses a preamble sequence with the first index value, the network device can consider that the terminal device has sent the first message.

[0200] [Corrected according to Rule 91, August 26, 2024] For example, a network device may group terminal devices based on a preamble ID. The network device may group terminal devices via SIB1 or higher-level configuration, and the grouping method includes:

[0201] [Corrected according to Rule 91 26.08.2024] Method 1: Terminal devices with preamble ID mod N = X are grouped together, X = {0,1,…,N-1}; the terminal devices in this group can send the first message to attempt to access the network device, where N is the number of groups, which can be predefined or configured by the network device.

[0202] [Corrected according to Rule 91, August 26, 2024] Method 2: Terminal devices with consecutive M preamble IDs are grouped together, for example: {0,1,…,M-1}, {M,M+1,M+2,…,2M-1},…,{M*NM,M*NM-2,…,M*N-1}, where N is the number of groups and M*N is the number of preambles reused on the same RO. Terminal devices in a specific group can send first information to attempt to access the network device.

[0203] [Correction based on Rule 91, August 26, 2024] In another embodiment, the random access first message uses any preamble sequence from the first preamble sequence set, and the preamble sequence belonging to the first preamble sequence set instructs the terminal device to send the first information.

[0204] [Corrected according to Rule 91, August 26, 2024] It is understood that preamble groups can be separately defined. A terminal device can use any preamble within that preamble group to indicate that it has sent first information and to access the network device by sending the first information. The network device can identify the terminal device by recognizing whether the preamble belongs to a preamble group.

[0205] [Correction 26.08.2024 according to Rule 91] In another embodiment, the second transmission resource includes a first RO, which instructs the terminal device to send the first information.

[0206] [Correction based on Rule 91, August 26, 2024] It should be noted that the first RO resource is different from the second RO resource currently used by the terminal device. For example, it may be adjacent to the second RO resource in the frequency domain or offset in the frequency domain; or it may be adjacent to the second RO resource in the time domain or offset in the time domain.

[0207] [Correction based on Rule 91, August 26, 2024] In some embodiments, when the method provided in this application fails to access the network device, the terminal device can fall back to the traditional random access method. Specifically, if the terminal device fails to access the network within a first time period after sending the first random access message for the first time, and / or after the first message, the terminal device determines to access the network using the traditional random access method.

[0208] [Correction 26.08.2024 according to Rule 91] In one embodiment, the first duration is determined based on predefined information.

[0209] [Correction 26.08.2024 based on Rule 91] In another implementation, the first duration can be determined based on network configuration information. For example, a network device can send seventh configuration information, and correspondingly, a terminal device can receive the seventh configuration information sent by the network device. The seventh configuration information is used to configure the first duration.

[0210] [Correction 26.08.2024 based on Rule 91] In some embodiments, the first duration can be implemented using a first timer. The first timer is started when the terminal device first sends a random access first message and / or when the first message is sent. If the terminal device has not yet accessed the network when the first timer expires, the terminal device determines to access the network using the conventional random access method.

[0211] [Corrected according to Rule 91, August 26, 2024] It should be understood that in related technologies, when a terminal device initially accesses the network, the terminal device can start a second timer. While the second timer is running, the MAC layer will initiate the PRACH process, in which it randomly selects a preamble, determines the power used to transmit the preamble, and sends the first message (or first PUSCH) on the first transmission resource. After this, the terminal device will attempt to detect the RAR. If the RAR is successfully received, the terminal device will continue the RACH process (e.g., sending Msg3, etc.); otherwise, the terminal device will increment the attempt count by 1, which is used to calculate the number of attempts made for preamble transmission. If the terminal device has not yet reached the maximum number of attempts, then the P... PRACH,target Increase delta to ramp up power and retry the preamble transmission process. If the maximum number of attempts has been reached and the RAR is still not successfully received, the terminal device will report to the higher layer. If the second timer has not stopped at this point, the higher layer may retry the PRACH process; otherwise, the PRACH access can be considered to have failed.

[0212] [Corrected according to Rule 91 26.08.2024] It is understood that the first timer can run simultaneously with the second timer, and the time range of the first timer is smaller than that of the second timer. This way, if the terminal device cannot access the network within the time range of the first timer, it can switch to the legacy mode to send PRACH, thus avoiding prolonging the network access time of the terminal device.

[0213] [Revised according to Rule 91, August 26, 2024] It is understood that when a terminal device fails to successfully access a network device using the method provided in the embodiments of this application, it can fall back to the traditional random access method for random access, thus ensuring normal communication.

[0214] [Correction 26.08.2024 based on Rule 91] The signal transmission method provided in the embodiments of this application will be described in detail below in conjunction with specific application scenarios.

[0215] [Correction based on Rule 91, August 26, 2024] In order to solve the problem of excessive PRACH resource overhead during random access, it is considered to send the SSB index selected by the terminal device to the network device by means of explicit indication after sending the preamble.

[0216] [Corrected according to Rule 91, August 26, 2024] Example 1

[0217] [Correction based on Rule 91, August 26, 2024] It should be noted that Example 1 applies to a four-step RACH process. Referring to Figure 6, the four-step RACH process includes the following steps:

[0218] [Correction based on Rule 91 26.08.2024] S1: The network device sends a first type of SSB or a first type of CSI-RS.

[0219] [Corrected according to Rule 91, August 26, 2024] It should be understood that the network device can send a first type of SSB or a first type of CSI-RS to inform the terminal device that it can use the method provided in this application to send the first information and Msg1 to access the network device. Accordingly, after detecting the first type of SSB or the first type of CSI-RS, the terminal device can send the first PRACH and the first information according to the method provided in the embodiments of this application.

[0220] [Corrected according to Rule 91, August 26, 2024] It should be noted that step S1 is optional. In addition to the method of S1, the network device can also configure the terminal device to send the first information and Msg1 to access the network device using the method provided in this application through configuration information (e.g., broadcast signaling MIB or SIB).

[0221] [Correction based on Rule 91 26.08.2024] S2: The terminal device sends the first PRACH on the second transmission resource.

[0222] [Corrected according to Rule 91, August 26, 2024] S3: The terminal device transmits first information using the first transmission resource; the first transmission resource and the second transmission resource do not overlap in the time domain. The first information may include one or more of the following:

[0223] [Correction 26.08.2024 according to Rule 91] The index of the first SSB or the index of the first CSI-RS associated with the first PRACH.

[0224] [Correction 26.08.2024 according to Rule 91] The terminal device obtains the RSRP based on the first SSB measurement associated with the first PRACH, or the RSRP obtained based on the first CSI-RS measurement.

[0225] [Revised according to Rule 91, 26.08.2024] In one embodiment, the resource location of the first transmission resource is predefined.

[0226] [Modified according to Rule 91, August 26, 2024] It is understood that the time-domain location and / or frequency-domain location of the resource location of the second transmission resource are predefined resources. This may include a combination of one or more of the following:

[0227] [Correction based on Rule 91, August 26, 2024] The period of the first transmission resource is predefined;

[0228] [Correction based on Rule 91, August 26, 2024] The time window for the first transmission resource is predefined;

[0229] [Correction based on Rule 91, August 26, 2024] The starting symbol position of the first transmission resource is predefined;

[0230] [Correction based on Rule 91, August 26, 2024] The number of symbols transmitted for the first transmission resource is predefined;

[0231] [Correction based on Rule 91, August 26, 2024] The number of RBs occupied by the first transmission resource is predefined;

[0232] [Correction based on Rule 91, August 26, 2024] The RB location occupied by the first transmission resource is predefined;

[0233] [Correction based on Rule 91, August 26, 2024] The RE occupied by the first transmission resource is predefined;

[0234] [Correction 26.08.2024 according to Rule 91] The starting position of the RB of the first transmission resource is predefined.

[0235] [Correction 26.08.2024 based on Rule 91] For example, the time window, starting symbol position, and number of symbols to be transmitted for the first transmission resource can be predefined. The terminal device can combine these three factors and send the first information to the network device within a predefined symbol position within a time window after the terminal device receives the SSB or CSI-RS. In this way, the network device only needs to detect at the predefined position, which can reduce latency.

[0236] [Correction based on Rule 91, 26.08.2024] It is understood that this implementation only needs to detect the first information according to predefined rules, without the need for signaling to indicate the location of the first transmission resource.

[0237] [Correction based on Rule 91, August 26, 2024] In another embodiment, the resource location of the first transmission resource is associated with the resource location of the second transmission resource. Specifically, the time-domain location of the first transmission resource is associated with the time-domain location of the second transmission resource, and / or the frequency-domain location of the first transmission resource is associated with the frequency-domain location of the second transmission resource, including a combination of one or more of the following:

[0238] [Correction based on Rule 91 26.08.2024] 1) The time slot position of the first transmission resource is a first offset relative to the time slot position of the second transmission resource; for example, the first offset may be a time slot offset relative to the starting time slot of RO, and the granularity of the first offset may be a time slot.

[0239] [Correction based on Rule 91 26.08.2024] 2) The symbol position of the first transmission resource is a second offset relative to the symbol position of the second transmission resource; for example, the second offset may be a symbol offset relative to the starting symbol position of RO, and the granularity of the second offset may be a symbol.

[0240] [Correction based on Rule 91 26.08.2024] 3) The frequency domain position of the first transmission resource is the same as that of the second transmission resource; for example, the starting frequency domain position of the second transmission resource and the first transmission resource are the same as the number of RBs or REs occupied in the frequency domain, that is, the resources overlap in the frequency domain.

[0241] [Corrected according to Rule 91 26.08.2024] 4) The frequency domain position of the first transmission resource is a third offset relative to the frequency domain position of the second transmission resource; for example, the third offset may be the offset of the first transmission resource relative to the starting frequency domain position of the second transmission resource, the starting frequency domain resource position is the starting frequency domain resource position corresponding to the first RO in the frequency domain, or the starting frequency domain resource position corresponding to the RO where PRACH is located.

[0242] [Corrected according to Rule 91 26.08.2024] 5) The RB position of the first transmission resource is the fourth offset relative to the RB position of the second transmission resource. Similar to the third offset, the description method is different, that is, the third offset is the offset relative to the starting RB or ending RB of the first transmission resource, while the granularity of the fourth offset can be RB.

[0243] [Corrected according to Rule 91 26.08.2024] 6) The RE position of the first transmission resource is the fifth offset relative to the RE position of the second transmission resource. Similar to the fourth offset, the granularity is different, that is, the fifth offset is the offset relative to the starting RE or ending RE of the second transmission resource, and the granularity of the fifth offset can be RE.

[0244] [Corrected according to Rule 91, August 26, 2024] In one example, the time slot position and symbol position of the first transmission resource are associated with the second transmission resource. The terminal device can determine the first transmission resource by combining the above two items. That is, the terminal device can determine the time slot position of the first transmission resource based on the time slot position of the second transmission resource and the first offset, and determine the symbol position of the first transmission resource based on the symbol position and the second offset of the second transmission resource, to obtain the final resource position of the first transmission resource (in this example, the frequency domain position of the first transmission resource can be the same as the frequency domain position of the second transmission resource).

[0245] [Corrected according to Rule 91, August 26, 2024] In one example: the time slot position, symbol position, and frequency domain position of the first transmission resource are associated with the second transmission resource. The terminal device can determine the first transmission resource by combining the above three items. That is, the terminal device can determine the time slot position of the first transmission resource based on the time slot position and the first offset of the second transmission resource, and determine the symbol position of the first transmission resource based on the symbol position and the second offset of the second transmission resource, thus obtaining the time domain position of the first transmission resource; in addition, the terminal device can determine the frequency domain position of the first transmission resource based on the frequency domain position and the third offset of the second transmission resource. In this way, the terminal device can determine the final resource position of the first transmission resource.

[0246] [Correction based on Rule 91, 26.08.2024] It is understood that in this embodiment, the first transmission resource is associated with the second transmission resource. The location of the first transmission resource can be obtained by configuring the offset value through signaling, which is more flexible than the predefined method, but requires more signaling resources.

[0247] [Correction 26.08.2024 according to Rule 91] In another embodiment, the resource location of the first transport resource is associated with the preamble of the first PRACH, or the resource location of the first transport resource is associated with the preamble group corresponding to the preamble of the first PRACH.

[0248] [Corrected according to Rule 91, August 26, 2024] It is understood that a preamble (or preamble index) / preamble corresponding to a preamble group (or preamble group index) can be associated with a first transmission resource, and different preambles / preamble groups can be associated with different first transmission resources. After receiving the preamble sent by the terminal device, the network device can receive the first information sent by the terminal device on the first transmission resource associated with that preamble / preamble group. No signaling is required to indicate the first transmission resource of the first information, saving signaling overhead.

[0249] [Corrected according to Rule 91 26.08.2024] It should be noted that in step S3, the first information can be carried on the first PUSCH, and the first transmission resource is the transmission resource of the first PUSCH.

[0250] [Correction 26.08.2024 based on Rule 91] In some embodiments, the transmission parameters of the first PUSCH include one or more of the following. These parameters can be configured through higher-layer parameters of the network device or can be predefined parameter values; this application does not limit this.

[0251] [Corrected according to Rule 91 26.08.2024] 1) MCS; The MCS of the first PUSCH can be configured by higher-level parameters or predefined.

[0252] [Corrected according to Rule 91 26.08.2024] 2) Enable or disable transport precoding. This can be configured by higher-level parameters or predefined, for example, predefined to enable transport and encoding or predefined to disable transport and encoding.

[0253] [Corrected according to Rule 91, August 26, 2024] 3) Number of PUSCH ports. It can be configured to any one of 1 to 4 ports, or predefined to use port 1.

[0254] [Correction 26.08.2024 according to Rule 91] 4) The second transport resource associated with the first information, or the associated preamble index, or preamble index group. That is, the first transport resource is associated with the preamble of the first PRACH.

[0255] [Correction 26.08.2024 based on Rule 91] In some embodiments, the configuration of the DMRS associated with the first PUSCH carrying the first information includes a combination of one or more of the following:

[0256] [Corrected according to Rule 91, August 26, 2024] The position of the DMRS symbol; the position of the DMRS symbol can be predefined, such as the first symbol in the first PUSCH. It can also be configured via higher-layer signaling.

[0257] [Corrected according to Rule 91, August 26, 2024] Number of symbols in DMRS; The number of symbols in DMRS can be predefined, such as 1 symbol. It can also be configured through higher-layer signaling.

[0258] [Corrected according to Rule 91 26.08.2024] DMRS CDM group; DMRS CDM group can be predefined or configured.

[0259] [Corrected according to Rule 91 26.08.2024] Type of DMRS; The type of DMRS can be predefined or configured.

[0260] [Corrected according to Rule 91 26.08.2024] S4: Network device sends RAR.

[0261] [Corrected according to Rule 91 26.08.2024] S5: The terminal device sends Msg3.

[0262] [Corrected according to Rule 91 26.08.2024] S6: Network device sends Msg4.

[0263] [Corrected according to Rule 91, August 26, 2024] Example 2

[0264] [Correction based on Rule 91, August 26, 2024] It should be noted that Example 2 is applied to a two-step RACH process. Referring to the schematic diagram of the two-step RACH process shown in Figure 7, the process includes the following steps:

[0265] [Correction based on Rule 91 26.08.2024] S1: The network device sends a first type of SSB or a first type of CSI-RS.

[0266] [Corrected according to Rule 91, August 26, 2024] It should be understood that the network device can send a first type of SSB or a first type of CSI-RS to inform the terminal device that it can use the method provided in this application to send the first information and Msg1 to access the network device. Accordingly, after detecting the first type of SSB or the first type of CSI-RS, the terminal device can send the first PRACH and the first information according to the method provided in the embodiments of this application.

[0267] [Corrected according to Rule 91, August 26, 2024] It should be noted that step S1 is optional. In addition to the method of S1, the network device can also configure the terminal device to send the first information and Msg1 to access the network device using the method provided in this application through configuration information (e.g., broadcast signaling MIB or SIB).

[0268] [Corrected according to Rule 91 26.08.2024] S2: The terminal device sends MsgA.

[0269] [Correction based on Rule 91 26.08.2024] It should be understood that for a two-step RACH, MsgA includes a preamble sequence (which can also be understood as the first PRACH) and a MsgA PUSCH whose temporal resources do not overlap with the preamble sequence (the first PRACH).

[0270] [Revised according to Rule 91, August 26, 2024] In one embodiment, the terminal device may add first information to the MsgA PUSCH. Exemplarily, the MsgA PUSCH may include one or more of the following:

[0271] [Correction 26.08.2024 according to Rule 91] Index of the first SSB or index of the first CSI-RS.

[0272] [Correction 26.08.2024 according to Rule 91] RSRP obtained from the first SSB measurement, or RSRP obtained from the first CSI-RS measurement.

[0273] [Revised according to Rule 91, August 26, 2024] In another embodiment, the terminal device may send the first message after MsgA PUSCH.

[0274] [Correction based on Rule 91, 26.08.2024] It should be noted that this implementation method is similar to Embodiment 1, and the relevant description in Embodiment 1 can be referred to. For the sake of brevity, it will not be repeated here.

[0275] [Corrected according to Rule 91 26.08.2024] S3: Network device sends MsgB.

[0276] [Corrected according to Rule 91, August 26, 2024] Example 3

[0277] [Correction 26.08.2024 based on Rule 91] In Embodiment 3, it is specifically described how to distinguish whether a terminal device accesses the network device through Embodiment 1 or Embodiment 2.

[0278] [Corrected according to Rule 91, August 26, 2024] In this embodiment of the application, the terminal device sends a first PRACH to the network device, and the network device can determine, based on the first PRACH, that the terminal device is sending first information through a second transmission resource. This includes the following methods:

[0279] [Correction based on Rule 91, August 26, 2024] 1) Distinguishing by the sequence of the first PRACH. The terminal device may use a specific sequence to distinguish the first PRACH from the PRACH in the prior art.

[0280] [Correction based on Rule 91 26.08.2024] 2) Distinguish by the RO resources of the first PRACH.

[0281] [Correction 26.08.2024 based on Rule 91] In one implementation, the association between the RO resources of the first PRACH and the SSB differs from the random access of related technologies.

[0282] [Correction 26.08.2024 according to Rule 91] In another embodiment, the RO resources of the first PRACH are different from the RO resources used by the terminal device in the related art, for example, the RO resources of the related art are adjacent in the frequency domain or offset in the frequency domain; for example, the RO resources of the related art are adjacent in the time domain or offset in the time domain.

[0283] [Correction 26.08.2024 based on Rule 91] 3) Differentiate by different preamble IDs.

[0284] [Corrected according to Rule 91, August 26, 2024] It is understood that multiple terminal devices can initiate random access using different preambles of the same RO, and network devices can group terminal devices according to the preamble ID. Network devices can group terminal devices through SIB1 or higher-layer configuration, and the grouping methods include:

[0285] [Corrected according to Rule 91 26.08.2024] Method 1: UEs with preamble ID mod N = X are grouped into a group, X = {0,1,…,N-1}; the terminal devices in this group attempt to access the network device by sending the first PRACH and the first information. This method is different from the prior art.

[0286] [Corrected according to Rule 91, August 26, 2024] Method 2: UEs with consecutive M preamble IDs are grouped together, for example: {0,1,…,M-1}, {M,M+1,M+2,…,2M-1},…,{M*NM,M*NM-2,…,M*N-1}, where N is the number of groups and M*N is the number of preambles multiplexed on the same RO. Terminal devices in specific groups attempt to access the network device by sending a first PRACH and first information. This method differs from existing technologies.

[0287] [Corrected according to Rule 91 26.08.2024] 4) Distinguish by the set to which the preamble belongs.

[0288] [Correction based on Rule 91, August 26, 2024] A network device receives a first PRACH carrying a specific set of preamble IDs and receives first information in a second transport resource. A separate preamble group is allocated for transmitting the preamble associated with the first information. Thus, the network device can identify the terminal device.

[0289] [Corrected according to Rule 91, August 26, 2024] Example 4

[0290] [Correction 26.08.2024 according to Rule 91] In Embodiment 4, the transmission power of the first PRACH and the first PUSCH is specifically described.

[0291] [Correction based on Rule 91, August 26, 2024] In this embodiment, the transmission power of the first PRACH is the same as that of the PRACH in related technologies. Alternatively, the transmission power of the first PUSCH can be determined according to the following formula. P PUSCH =min{P cmax ,Po+alpha*PL+f(i,l)}

[0292] [Correction based on Rule 91, August 26, 2024] It should be noted that the PL can determine the path loss based on the first type of SSB or the SSB resources used by the terminal device to obtain the MIB, or the resource index used to determine the PL is the same as the reference signal associated with the reference signal sent by the terminal device for the first PRACH.

[0293] [Corrected according to Rule 91 26.08.2024] It should also be noted that the Po can be configured through the configuration information related to the first PRACH, or by using the Po corresponding to a predefined index.

[0294] [Correction 26.08.2024 according to Rule 91] For the power priority of the first PUSCH, wherein the power priority of the first PUSCH is the same as or lower than the power priority of the associated first PRACH.

[0295] [Corrected according to Rule 91, August 26, 2024] Add the power priority of the first PUSCH to the relevant channel power priority order (in descending order of priority):

[0296] [Corrected according to Rule 91 26.08.2024] 1) PRACH transmission on the PCell;

[0297] [Corrected according to Rule 91 26.08.2024] 2) First PUSCH transmission of PCcell; It should be understood that the first PUSCH transmission of PCcell has the same priority as the PRACH transmission of PCcell, or the PRACH priority of PCcell is higher than the first PUSCH priority of PCcell.

[0298] [Corrected according to Rule 91 26.08.2024] 3) PUSCH or PUCCH transmissions with a larger priority index

[0299] [Corrected according to Rule 91 26.08.2024] 4) PUSCH or PUCCH transmissions with the same priority index have the following contents in order of priority:

[0300] [Correction 26.08.2024 according to Rule 91] PUCCH transmission with HARQ-ACK information and / or SR and / or LRR, or PUSCH transmission with HARQ-ACK information of the priority index;

[0301] [Correction based on Rule 91, August 26, 2024] PUCCH transmission with CSI or PUSCH transmission with CSI;

[0302] [Corrected according to Rule 91 26.08.2024] PUSCH transmission without HARQ-ACK information or CSI, or PUSCH transmission in a two-step random access procedure, or PUSCH transmission on the PCell.

[0303] [Corrected according to Rule 91 26.08.2024] 5) SRS transmission, PRACH transmission on a serving cell other than the PCell;

[0304] [Correction based on Rule 91 26.08.2024] 6) First PUSCH of non-PCcell; It should be understood that the first PUSCH of non-PCcell has the same priority as or lower than the PRACH of non-PCcell.

[0305] [Corrected according to Rule 91, August 26, 2024] Example 5

[0306] [Correction 26.08.2024 based on Rule 91] In Example 5, the fallback mechanism of the terminal device is specifically described.

[0307] [Correction based on Rule 91, August 26, 2024] When a terminal device fails to access the network using the solution in this case, it needs to switch to the legacy access procedure to continue attempting to access the network. The conditions for switching may include:

[0308] [Correction based on Rule 91, August 26, 2024] When a terminal device initially accesses the network (e.g., sends a PRACH or first message for the first time), a first timer is started. When the first timer expires, the device falls back to legacy mode to send the PRACH; this timer is configured in SIB1, and the first timer is used for the terminal device to switch to legacy mode to send the PRACH.

[0309] [Corrected according to Rule 91, August 26, 2024] It should be understood that in related technologies, when a terminal device initially accesses the network, the terminal device can start a second timer. While the second timer is running, the MAC layer will initiate the PRACH process, in which it randomly selects a preamble, determines the power used to transmit the preamble, and sends the first message (or first PUSCH) on the first transmission resource. After this, the terminal device will attempt to detect the RAR. If the RAR is successfully received, the terminal device will continue the RACH process (e.g., sending Msg3, etc.); otherwise, the terminal device will increment the attempt count by 1, which is used to calculate the number of attempts made for preamble transmission. If the terminal device has not yet reached the maximum number of attempts, then the P... PRACH,target Increase delta to ramp up power and retry the preamble transmission process. If the maximum number of attempts has been reached and the RAR is still not successfully received, the terminal device will report to the higher layer. If the second timer has not stopped at this point, the higher layer may retry the PRACH process; otherwise, the PRACH access can be considered to have failed.

[0310] [Corrected according to Rule 91 26.08.2024] It is understood that the first timer can run simultaneously with the second timer, and the time range of the first timer is smaller than that of the second timer. This way, if the terminal device cannot access the network within the time range of the first timer, it can switch to the legacy mode to send PRACH, thus avoiding prolonging the network access time of the terminal device.

[0311] [Corrected according to Rule 91, August 26, 2024] The preferred embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the specific details of the above embodiments.
