Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety assurance. Typical characteristics of mMTC include high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan.

[0153] In some implementations, the terminal can initiate a random access procedure to the network side. This could be a 4-step random access procedure as shown in Figure 1B or a 2-step random access procedure as shown in Figure 1C.

[0154] As shown in Figure 1B, in the 4-step random access process, the terminal sends MSG1, receives MSG2, sends MSG3, and receives MSG4 in a cell. The 4-step random access process may include the following steps:

[0155] Step S1101, the terminal (UE) sends MSG1 to the base station (gNB), wherein MSG1 includes a Random Access (RA) preamble:

[0156] In the first step, the terminal determines the relationship between the Synchronization Signal Block (SSB) and Physical Random Access Channel (PRACH) resources and / or preamble based on the higher-layer configuration.

[0157] The terminal can receive a set of SSBs and determine their Reference Signal Receiving Power (RSRP) value, and select an appropriate SSB based on a threshold.

[0158] The range of RACH resources and preamble resources is determined based on the selected SSB and the correspondence between SSB and RACH resources;

[0159] The terminal selects a preamble group based on the size of MSG3, and then randomly selects a preamble within the preamble group;

[0160] Set the target received power as: preambleReceivedTargetPower + DELTA_PREAMBLE + (PREAMBLE_POWER_RAMPING_COUNTER – 1) × powerRampingStep;

[0161] Wherein, preambleReceivedTargetPower represents the target power for receiving the preamble, DELTA_PREAMBLE represents the preamble power offset, PREAMBLE_POWER_RAMPING_COUNTER represents the number of preamble power ramps, and powerRampingStep represents the power ramp step size.

[0162] The terminal transmits the sequence on the PRACH time-frequency domain resource.

[0163] In step S1102, the network device sends MSG2 to the terminal, wherein MSG2 includes a Random Access Response (RAR). The terminal 101 receives MSG2.

[0164] In the second step, the RA-RNTI is determined based on the time-frequency domain resources of the PRACH sent by MSG1, and the RA-RNTI is calculated:

[0165] RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id,

[0166] Wherein, s_id represents the index of the first OFDM symbol of the PRACH timing, t_id represents the index of the first slot of the PRACH timing in the system frame, f_id represents the index of the PRACH timing in the frequency domain, and ul_carrier_id represents the uplink carrier index used to transmit MSG1.

[0167] The terminal opens the RAR time window (RA-Response Window) at the first Physical Downlink Control Channel (PDCCH) occasion after sending the preamble, and listens to the PDCCH scrambled with RA-RNTI during the operation of the time window in order to receive the RAR corresponding to RA-RNTI.

[0168] If no RAR is received within the RAR monitoring window, or if no RAR corresponding to the Random Access Preamble Identifier (RAPID) is received, then power ramping is performed and MSG1 retransmission is executed. Whether ramping is performed depends on whether the beam is switched.

[0169] If a RAR is received within the RAR monitoring window, and if it is the first time a RAR has been received, the Medium Access Control Protocol Data Unit (MAC PDU) is obtained from the multiplexing and assembly entity and stored in the MSG3 buffer.

[0170] Step S1103: The terminal sends MSG3 to the network device, wherein MSG3 includes the scheduled transmission:

[0171] In the third step, if the terminal does not have its own Cell-Radio Network Temporary Identifier (C-RNTI), the execution of the RACH is triggered by the Common Control Channel (CCCH), and MSG3 generates a MAC PDU for the CCCH Service Data Unit (SDU) input; if the terminal has its own C-RNTI, the terminal indicates that the multiplexing and assembly entity includes a C-RNTI Media Access Control Control Element (MAC CE), and MSG3 generates a MAC PDU for the C-RNTI MAC CE input.

[0172] Obtain the MAC PDU from the MSG3 buffer and transmit the MAC PDU based on the Uplink Grant (UL Grant) in the RAR;

[0173] After MSG3 is transmitted, a random access conflict resolution timer (RA) is started and the PDCCH is listened to during the timer's operation. If MSG3 contains C-RNTI MAC CE, the terminal listens to the PDCCH scrambled with that C-RNTI. If MSG3 does not contain C-RNTI MAC CE, the terminal listens to a temporary C-RNTI and receives MSG4.

[0174] When MSG3 performs a Hybrid Automatic Repeat reQuest (HARQ) retransmission, the timer is restarted; the terminal will continue to listen to PDCCH until the timer expires or stops; MSG3 HARQ retransmission is scrambled and scheduled based on temporary C-RNTI.

[0175] Step S1104: The network device sends MSG4 to the terminal, where MSG4 is used for conflict resolution.

[0176] In the fourth step, if MSG3 contains C-RNTI MAC CE, the terminal listens for the PDCCH scrambled by C-RNTI. If it hears the PDCCH, the conflict is considered to have been resolved successfully; if it does not hear the PDCCH, the conflict is considered to have been resolved unsuccessfully.

[0177] If MSG3 does not contain C-RNTI MAC CE, the terminal listens for temporary C-RNTI and receives MSG4. If MSG4 is received and it matches CCCH SDU, the conflict resolution is successful; otherwise, the conflict resolution fails.

[0178] If conflict resolution fails, the terminal will perform a power ramp (whether it ramps depends on whether beam is switched) and resend MSG1.

[0179] As shown in Figure 1C, the two-step random access process may include the following steps:

[0180] Step S1201: The network device assigns a random access preamble to the terminal.

[0181] Step S1202: The terminal sends MSG1 to the network device. MSG1 includes a random access preamble (first step).

[0182] Step S1203: The network device sends MSG2 to the terminal, which includes a random access response (second step).

[0183] In some implementations, in NR, in addition to the normal uplink (NUL), a supplementary uplink (SUL) frequency is introduced in a cell to improve uplink coverage in the NR high-frequency band. Terminal uplink power is limited, and the NR spectrum (high frequency, high propagation loss) has a relatively high frequency, thus limiting uplink coverage. To improve uplink coverage, utilizing the LTE spectrum (relatively lower frequency) as the uplink can enhance uplink coverage. Specifically:

[0184] Two uplinks (UL) and one downlink (DL) belong to the same cell, and at most one Physical Uplink Shared Channel (PUSCH) can be used for transmission at any given time.

[0185] Unless the network side explicitly instructs the terminal to use a UL, the terminal determines the UL selection based on a measurement threshold, which is configured in the system broadcast.

[0186] Dynamic switching between two UL carriers is possible, indicated by DCI.

[0187] In some implementations, a set of RACH resource configurations is configured independently on the NUL and SUL, including independent per-carrier preamble configurations, independent per-carrier RO resource configurations, independent RACH control parameter configurations, and so on.

[0188] In some implementations of the Network Energy Saving (NES) feature in Release 19 (R19), to support network energy saving, adaptive RACH configuration can be provided in addition to the conventional (legacy) RACH resource configuration, such as configuring an additional set of RACH resources. This additional set of RACH resources can be activated or deactivated by the network. In other scenarios, other methods or approaches for activating RACH configurations may also be included.

[0189] In some implementations, activating RACH resource configuration can effectively increase RACH capacity. However, after activating RACH resource configuration, there are different RACH resource configuration information, and how the terminal should choose is a problem that needs to be clarified. For example, if RO is randomly selected from different RACH resource configurations, there is a problem that the load distribution cannot be effectively controlled based on network-side demand.

[0190] Figure 2A is an interactive schematic diagram illustrating a method for receiving and transmitting instruction information according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to a method for receiving and transmitting instruction information, the method including:

[0191] In step S2101, network device 102 sends at least one RACH configuration information to terminal 101.

[0192] In some embodiments, terminal 101 receives at least one RACH configuration information.

[0193] Optionally, terminal 101 can be in RRC idle state (RRC_IDLE), RRC inactive state (RRC_INACTIVE), or RRC connected state (RRC_CONNECTED).

[0194] In some embodiments, network device 102 may send at least one RACH configuration information via a signaling signal, or each RACH configuration information may be sent separately via a signaling signal.

[0195] Optionally, at least one RACH configuration information can also be referred to as at least one set of RACH configuration information.

[0196] Optionally, RACH configuration information can also be referred to as RACH resource configuration or RACH resource configuration information. The related resources or information configured or included in the RACH configuration information can be referred to as RACH resources.

[0197] In some embodiments, at least one RACH configuration information satisfies at least one of the following:

[0198] Each RACH configuration information is associated with an index;

[0199] Each RACH configuration information is associated with a corresponding preamble information;

[0200] Each RACH configuration information is associated with a corresponding RO;

[0201] At least one RACH configuration file includes the default active RACH configuration file;

[0202] At least one RACH configuration information includes RACH configuration information that has been activated or deactivated by the network device.

[0203] Optionally, each RACH configuration information is associated with an index, which identifies each RACH configuration information. For example, N RACH configuration information are associated with indices 0, 1, 3, ..., N. Each RACH configuration information may include a corresponding RACH resource, which may refer to at least one of the following: preamble, RO or RO resource, RACH control parameter configuration, etc.

[0204] Optionally, each RACH configuration information is associated with a preamble information, such as a configuration of 64 preambles.

[0205] In one example, each RACH configuration information is associated with a corresponding preamble information or preamble configuration. Preamble information can be configured per RACH configuration information, and preamble information associated with different RACH configuration information can be independent of each other. Preamble information can also be configured per RACH configuration group; for example, multiple RACH configuration information within the same RACH configuration group can be associated with the same preamble information. Preamble information associated with different RACH configuration groups can be independent of each other, such as configuring preamble information per carrier.

[0206] Optionally, each RACH configuration information is associated with a corresponding RO, RO resource, or RO resource configuration, and the ROs associated with different RACH configuration information can be independent of each other. Optionally, ROs can be configured on a per-carrier basis (per-carrier RO).

[0207] Optionally, each RACH configuration information is associated with a corresponding RACH control parameter configuration, and the RACH control parameter configurations associated with different RACH configuration information can be independent of each other.

[0208] Optionally, at least one RACH configuration information includes a default activated RACH configuration information, such as regular or legacy RACH configuration information. For example, under NES features, the RACH configuration information includes legacy RACH configuration information and additional RACH configuration information, where the legacy RACH configuration information can be activated by default, and the additional RACH configuration information can be activated or deactivated via network signaling.

[0209] Optionally, at least one RACH configuration information includes RACH configuration information activated or deactivated by a network device. The RACH configuration information activated or deactivated by a network device is, for example, RACH configuration information configured as an additional feature under NES. The RACH configuration information is activated or deactivated by network device 102. For example, network device 102 can activate the RACH configuration information through DCI such as paging DCI, RAR, or MAC CE.

[0210] In some embodiments, network device 102 sends at least one RACH configuration message via RRC signaling or System Information (SI). Optionally, network device 102 broadcasts at least one RACH configuration message via SI.

[0211] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0212] In some embodiments, the terms “downlink control information (DCI),” “downlink (DL) assignment,” “DL DCI,” “uplink (UL) grant,” and “UL DCI” can be used interchangeably.

[0213] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.

[0214] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transmit,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0215] In step S2102, network device 102 sends instruction information to terminal 101.

[0216] In some embodiments, terminal 101 receives instruction information.

[0217] In some embodiments, each RACH configuration information is associated with a random access information in at least one RACH configuration information.

[0218] Optionally, random access information can also be referred to as RACH resources, including at least one of preamble information, RO, and RACH control parameters. In this embodiment, RO or RO resources are used as examples to describe how terminal 101 selects RO from at least one RACH configuration information based on indication information. Other random access information can be found in the descriptions of related embodiments.

[0219] In some embodiments, the indication information includes a first parameter, which is used to determine random access information based on at least one RACH configuration information.

[0220] Optionally, the first parameter is used to select one RACH configuration information from at least one RACH configuration information and determine its associated RACH resource as random access information.

[0221] Optionally, the first parameter may occupy several bits to explicitly indicate the selection method of RACH configuration information, or to explicitly indicate an index of RACH configuration information.

[0222] Optionally, the first parameter can be used by the terminal to select RACH configuration information with a certain probability, so that the selection can be made under the control of the network device to achieve load balancing based on network control.

[0223] In some embodiments, the first parameter is a random factor.

[0224] Optionally, the random factor is a random number between 0 and 1, for example, 0.6.

[0225] Optionally, the random factor is independent of at least one RACH configuration information.

[0226] In some embodiments, network device 102 sends indication information via RRC signaling or SI.

[0227] Optionally, network device 102 sends at least one RACH configuration information and indication information through the same RRC signaling, for example, sending indication information through RRC signaling carrying at least one RACH configuration information. Alternatively, network device 102 sends at least one RACH configuration information and indication information through the same SI. Optionally, steps S2101 and S2102 in this optional embodiment can be executed synchronously.

[0228] Optionally, network device 102 may send at least one RACH configuration information and indication information through different signaling methods.

[0229] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0230] Step S2103: Terminal 101 generates a random number.

[0231] Optionally, the random number can be any random number (random A), for example, 0.8.

[0232] In some embodiments, after receiving the indication information, if the first parameter is a random factor, the terminal 101 can randomly generate a random number.

[0233] Optionally, the terminal may generate random numbers based on protocol definitions, network device instructions, or terminal-defined random algorithms.

[0234] In step S2104, terminal 101 determines random access information based on the random factor and random number.

[0235] Optionally, terminal 101 determines random access information based on the relationship between the random factor and the random number, either according to the default activated RACH configuration information or the RACH configuration information activated by the network device.

[0236] In some embodiments, the random number is greater than the random factor, and the random access information corresponds to either the default activated RACH configuration information or the RACH configuration information activated by the network device.

[0237] In some embodiments, the random number is less than or equal to the random factor, and the random access information corresponds to either the default activated RACH configuration information or the RACH configuration information activated by the network device.

[0238] For example, when the random number is greater than the random factor, the random access information corresponds to the default activated RACH configuration information. Therefore, the terminal can determine the random access information based on the default activated RACH configuration information, such as performing random access based on the RO associated with the legacy RACH configuration information. When the random number is less than or equal to the random factor, the random access information corresponds to the RACH configuration information activated by the network device. Therefore, the terminal can determine the random access information based on the activated RACH configuration information, such as performing random access based on the RO associated with the additional RACH configuration information.

[0239] In one example, the random factor is factor, the random number is A, and at least one RACH configuration information includes the default activated RACH configuration information 1 and the RACH configuration information 2 activated by the network device. If A > factor, the random access information corresponds to RACH configuration information 1, and the terminal can select the random access information contained in or associated with RACH configuration information 1, such as selecting the RO contained in or associated with RACH configuration information 1. If A ≤ factor, the random access information corresponds to RACH configuration information 2, and the terminal can select the random access information contained in or associated with RACH configuration information 2, such as selecting the RO contained in or associated with RACH configuration information 2.

[0240] For example, when the random number is greater than the random factor, the random access information corresponds to the RACH configuration information activated by the network device; when the random number is less than or equal to the random factor, the random access information corresponds to the default activated RACH configuration information.

[0241] In one example, the random factor is factor, the random number is A, and at least one RACH configuration information includes the default activated RACH configuration information 1 and the RACH configuration information 2 activated by the network device. If A > factor, the random access information corresponds to RACH configuration information 2, and the terminal can select the random access information contained in or associated with RACH configuration information 2, such as selecting the RO contained in or associated with RACH configuration information 2. If A ≤ factor, the random access information corresponds to RACH configuration information 1, and the terminal can select the random access information contained in or associated with RACH configuration information 1, such as selecting the RO contained in or associated with RACH configuration information 1.

[0242] In some embodiments, the RACH configuration information configured by the network device may include multiple default-activated RACH configuration information and / or multiple RACH configuration information activated by the network device, such as in at least one RACH configuration information.

[0243] In some embodiments, when at least one RACH configuration information includes multiple default-activated RACH configuration information, the terminal can determine random access information based on any one of the multiple default-activated RACH configuration information.

[0244] Optionally, in conjunction with the description of the foregoing embodiments, when the terminal determines the selection of random access information based on the default activated RACH configuration information according to the relationship between the random factor and the random number, if at least one RACH configuration information includes multiple default activated RACH configuration information, the terminal can randomly select one of the multiple default activated RACH configuration information, and then select or determine the random access information based on the selected default activated RACH configuration information, such as selecting the RO of the default activated RACH configuration information.

[0245] In one example, the terminal determines the random access information based on the default activated RACH configuration information according to the random factor and random number. That is, the random access information corresponds to the default activated RACH configuration information. If at least one RACH configuration information includes the default activated RACH configuration information 1, the default activated RACH configuration information 2, and the RACH configuration information 3 activated by the network device, the random access information can be determined according to RACH configuration information 1, such as selecting the RO of RACH configuration information 1, or the random access information can be determined according to RACH configuration information 2, such as selecting the RO of RACH configuration information 2.

[0246] In some embodiments, when at least one RACH configuration information includes multiple RACH configuration information activated by a network device, the terminal can determine random access information based on any one of the multiple RACH configuration information activated by the network device.

[0247] Optionally, in conjunction with the description of the foregoing embodiments, when the terminal determines the selection of random access information based on the default activated RACH configuration information according to the relationship between the random factor and the random number, if at least one RACH configuration information includes multiple RACH configuration information activated by the network device, the terminal may randomly select one of the multiple RACH configuration information activated by the network device, and then select or determine the random access information based on the selected RACH configuration information activated by the network device.

[0248] In one example, the terminal determines the random access information based on the RACH configuration information activated by the network device according to the random factor and the random number. That is, the random access information corresponds to the RACH configuration information activated by the network device. If at least one RACH configuration information includes the default activated RACH configuration information 1, the RACH configuration information 2 activated by the network device, and the RACH configuration information 3 activated by the network device, the random access information can be determined according to RACH configuration information 2, such as selecting the RO of RACH configuration information 2, or the random access information can be determined according to RACH configuration information 3, such as selecting the RO of RACH configuration information 3.

[0249] In some embodiments, the random access information corresponds to the default activated RACH configuration information or the RACH configuration information activated by the network device, or the random access information is determined according to any one of the multiple default activated RACH configuration information or any one of the multiple RACH configuration information activated by the network device. This indicates that the RACH resource associated with the corresponding RACH configuration information is selected as the random access information, such as at least one of the preamble information and RO associated with the corresponding RACH configuration information as the random access information.

[0250] In step S2105, terminal 101 sends MSG1 to network device 102 based on random access information.

[0251] In some embodiments, network device 102 receives MSG1 based on random access information.

[0252] In some embodiments, terminal 101 sends MSG1 to network device 102 through the RACH resources associated with the determined RACH configuration information.

[0253] Optionally, MSG1 includes preamble information associated with the determined RACH configuration information.

[0254] Optionally, terminal 101 sends MSG1 on the time-frequency resource specified by the RO associated with the determined RACH configuration information. MSG1 may carry the preamble associated with the RACH configuration information.

[0255] In some embodiments, after the terminal 101 determines the random access information, it can initiate a random access procedure to the network device 102 based on the random access information, such as sending MSG1. After sending MSG1, the method may further include steps S1102-S1104 as shown in FIG1B, so that the terminal establishes a random connection with the network device, which will not be described in detail here.

[0256] The method for receiving and transmitting instruction information according to the embodiments of this disclosure may include at least one of steps S2101 to S2105. For example, step S2102 may be implemented as a separate embodiment, and steps S2102 and S2104 may be implemented as separate embodiments, but are not limited thereto.

[0257] In some embodiments, steps S2101 and S2102 may be performed in an alternate order or simultaneously.

[0258] In some embodiments, steps S2101, S2103, S2104, and S2105 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0259] In some embodiments, steps S2101, S2103, and S2105 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0260] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0261] Figure 2B is an interactive schematic diagram illustrating a method for receiving and transmitting instruction information according to an embodiment of the present disclosure. As shown in Figure 2B, the present disclosure relates to a method for receiving and transmitting instruction information, the method including:

[0262] In step S2201, network device 102 sends at least one RACH configuration information to terminal 101.

[0263] In some embodiments, the implementation of step S2201 can be referred to the implementation of step S2101 in FIG2A, and will not be repeated here.

[0264] In step S2202, network device 102 sends instruction information to terminal 101.

[0265] In some embodiments, terminal 101 receives instruction information.

[0266] In some embodiments, the indication information includes a first parameter, which is used to determine random access information based on at least one RACH configuration information.

[0267] In some embodiments, the first parameter is a numerical range associated with each RACH configuration information.

[0268] Alternatively, the numerical range can be replaced with a numerical interval.

[0269] Optionally, each RACH configuration information in at least one RACH configuration information may be associated with a different data range.

[0270] Optionally, the numerical range associated with each RACH configuration information can be a range between 0 and 1. For example, the numerical range associated with RACH configuration information 1 is 0.3 to 0.5 or [0.3, 0.5], and the numerical range associated with RACH configuration information 2 is 0.5 to 0.7 or [0.5, 0.7].

[0271] In some embodiments, when at least one RACH configuration information includes multiple default-activated RACH configuration information, the first parameter is a numerical range associated with each RACH configuration information.

[0272] In some embodiments, when at least one RACH configuration information includes multiple RACH configuration information activated by a network device, the first parameter is a numerical range associated with each RACH configuration information.

[0273] In some embodiments, when at least one RACH configuration information includes multiple default-activated RACH configuration information and multiple RACH configuration information activated by network devices, the first parameter is a numerical range associated with each RACH configuration information.

[0274] In some embodiments, other implementations of the indication information in step S2202 can be found in the implementation of step S2102 in FIG2A, and will not be repeated here.

[0275] Step S2203: Terminal 101 generates a random number.

[0276] In some embodiments, the implementation of step S2203 can be referred to the implementation of step S2103 in FIG2A, and will not be repeated here.

[0277] In step S2204, terminal 101 determines random access information based on RACH configuration information associated with the numerical range of the random number.

[0278] In some embodiments, when the first parameter is a numerical range associated with each RACH configuration information, the terminal can determine the random access information based on the RACH configuration information associated with the numerical range of the random number.

[0279] Optionally, the range of values ​​in which the random number falls, i.e. the range of values ​​into which the random number falls.

[0280] In one example, when at least one RACH configuration information includes RACH configuration information 1, RACH configuration information 2, and RACH configuration information 3, it is assumed that the numerical range associated with RACH configuration information 1 is 0 to 0.3, the numerical range associated with RACH configuration information 2 is 0.3 to 0.7, and the numerical range associated with RACH configuration information 3 is 0.7 to 1.0. If the random number generated by the terminal is 0.8, the terminal can determine random access information or RACH resources such as ROs based on RACH configuration information 3. For example, the terminal performs random access using ROs contained in or associated with RACH configuration information 3.

[0281] In this example, RACH configuration information 1, RACH configuration information 2, and RACH configuration information 3 can all be RACH configuration information activated by default, or all of them can be RACH configuration information activated by the network device, or some can be RACH configuration information activated by default and the rest can be RACH configuration information activated by the network device.

[0282] In step S2205, terminal 101 sends MSG1 to network device 102 based on random access information.

[0283] In some embodiments, the implementation of step S2205 can be referred to the implementation of step S2105 in FIG2A, and will not be repeated here.

For example, step S2202 may be implemented as a separate embodiment, and steps S2202 and S2204 may be implemented as separate embodiments, but are not limited thereto.

[0285] In some embodiments, steps S2201 and S2202 may be performed in an alternate order or simultaneously.

[0286] In some embodiments, steps S2201, S2203, S2204, and S2205 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0287] In some embodiments, steps S2201, S2203, and S2205 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0289] Figure 2C is an interactive schematic diagram illustrating a method for receiving and transmitting instruction information according to an embodiment of the present disclosure. As shown in Figure 2C, the present disclosure relates to a method for receiving and transmitting instruction information, the method including:

[0291] In some embodiments, the implementation of step S2301 can be referred to the implementation of step S2101 in FIG2A, and will not be repeated here.

[0292] In step S2302, network device 102 sends instruction information to terminal 101.

[0293] In some embodiments, terminal 101 receives instruction information.

[0294] In some embodiments, the indication information includes a first parameter, which is used to determine random access information based on at least one RACH configuration information.

[0295] In some embodiments, the first parameter is an integer N.

[0296] Optionally, the integer N is independent of at least one RACH configuration information.

[0297] Optionally, the integer N is a random integer.

[0298] In some embodiments, other implementations of the indication information in step S2302 can be found in the implementation of step S2102 in FIG2A, and will not be repeated here.

[0299] In step S2303, terminal 101 sends the first MSG1 to network device 102.

[0300] In some embodiments, network device 102 receives a first MSG1.

[0301] In some embodiments, network device 102 does not receive the first MSG1.

[0302] In some embodiments, network device 102 does not expect to receive the first MSG1.

[0303] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time-domain and / or frequency-domain resources, or as not performing subsequent processing on the data and / or instructions received.

[0304] In some embodiments, terminal 101 sends the first MSG1 based on the RACH resource associated with any one of the RACH configuration information in at least one RACH configuration information; or terminal 101 sends the first MSG1 by default based on legacy RACH configuration information.

[0305] Optionally, when the terminal sends the first MSG1, the RACH configuration information used includes associated RO and / or preamble information. For example, terminal 101 sends the first MSG1 on the RO resource associated with the legacy RACH configuration information.

[0306] In some embodiments, the first MSG1 is used to indicate a certain MSG1 sent by the terminal, and "first" is used to distinguish it from the second MSG1 resent below.

[0307] In step S2304, terminal 101 determines random access information based on integer N.

[0308] In some embodiments, when terminal 101 does not receive MSG2 corresponding to the first MSG1, it determines random access information based on the integer N.

[0309] Alternatively, MSG2 can also be referred to as RAR.

[0310] Optionally, if terminal 101 does not receive MSG2 corresponding to the first MSG1, it may be because it did not receive any MSG2 after sending the first MSG1, or it may be because it did not receive the corresponding MSG2 of its own terminal after sending the first MSG1.

[0311] Optionally, if there is a conflict in the random access of different terminals 101, terminal 101 may not be able to receive the corresponding MSG2.

[0312] In some embodiments, the terminal may select random access information based on whether the integer N satisfies a first condition.

[0313] Optionally, if the integer N satisfies the first condition, the terminal can determine the random access information based on the first MSG1 or based on at least one of the RACH configuration information.

[0314] Optionally, random access information is determined based on the first MSG1, indicating that the terminal can use the RACH resource such as RO used when sending the first MSG1 as the random access information such as RO.

[0315] Optionally, determining random access information based on one of the at least one RACH configuration information indicates that the terminal may use the RACH resource associated with any of the at least one RACH configuration information, such as RO, as the random access information, such as RO; or the terminal may use the RACH resource associated with any of the at least one RACH configuration information, except for the RACH configuration information corresponding to the first MSG1, as the random access information.

[0316] In some embodiments, when the integer N satisfies the first condition, random access information is determined according to the first MSG1; when the integer N does not satisfy the first condition, random access information is determined according to one of at least one RACH configuration information.

[0317] In some embodiments, when the integer N satisfies the first condition, random access information is determined according to one of at least one RACH configuration information; when the integer N does not satisfy the first condition, random access information is determined according to the first MSG1.

[0318] In some embodiments, the first condition is at least one of the following:

[0319] RA-RNTI mod N = 0;

[0320] Preamble ID mod N = 0;

[0321] Among them, the RA-RNTI or preamble identifier corresponds to the first MSG1. If it is the RA-RNTI or preamble identifier associated with the transmission of the first MSG1, mod represents the modulo operation.

[0322] Optionally, for different terminals, terminals that meet the first condition mentioned above, such as terminals that satisfy RA-RNTI mod N=0 or preamble identifier mod N=0, can continue to select the RACH resource corresponding to the first MSG1; or select the RACH resource of one RACH configuration information from at least one RACH configuration information, such as selecting the RACH resource of the RACH configuration information activated by the network device.

[0323] In some embodiments, when the terminal 101 receives the MSG2 corresponding to the first MSG1, steps S2304 and S2305 can be omitted, and steps S1103-S1104 shown in FIG1B can be executed.

[0324] In step S2305, terminal 101 retransmits the second MSG1 based on the random access information.

[0325] In some embodiments, network device 102 receives a second MSG1 based on random access information.

[0326] In some embodiments, when the terminal 101 does not receive the MSG2 corresponding to the first MSG1, it retransmits the second MSG1 according to the random access information.

[0327] Optionally, the second MSG1 is used to indicate an MSG1 retransmitted by the terminal after the first MSG1.

[0328] In some embodiments, terminal 101 sends a second MSG1 to network device 102 through a determined RACH resource such as RO.

[0329] Optionally, when determining random access information based on the first MSG1, if the RACH resource corresponding to the first MSG1 is selected, the RO where the second MSG1 and the first MSG1 are located can be the same.

[0330] Optionally, when determining random access information based on one of the at least one RACH configuration information, the second MSG2 is sent through the RACH resource associated with any of the at least one RACH configuration information, and the ROs where the second MSG1 and the first MSG1 are located may be different.

[0331] In some embodiments, after terminal 101 sends the second MSG1 to network device 102 according to random access information, the process further includes steps S1102-S1104 as shown in FIG1B.

[0332] The method for receiving and sending instruction information according to the embodiments of this disclosure may include at least one of steps S2301 to S2305. For example, step S2302 may be implemented as a separate embodiment, and steps S2302, S2303, and S2304 may be implemented as separate embodiments, but are not limited thereto.

[0333] In some embodiments, steps S2301 and S2302 may be performed in an alternate order or simultaneously.

[0334] In some embodiments, steps S2302 and S2303 can be swapped in order. For example, network device 102 can send an indication message in the event of failure to receive the first MSG1 or conflict between the first MSG1 messages of different terminals.

[0335] In some embodiments, steps S2301, S2303, S2304, and S2305 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0336] In some embodiments, steps S2301, S2303, and S2305 are optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0368] This disclosure provides a method for receiving and sending instruction information, which effectively controls the terminal to select RO resources to initiate access based on network-side configuration parameters, and rationally utilizes RACH resources based on network-side control to achieve load balancing.

[0369] In some embodiments, RACH resources and RO resources may correspond to the random access information in the above embodiments.

[0370] To facilitate understanding of the embodiments of this disclosure, some embodiments are listed below:

[0371] In some embodiments, the network side is configured with at least one RACH configuration, which is used to determine the configuration of RACH RO.

[0372] Optionally, the network side configures at least one RACH configuration via system broadcast information.

[0373] In some embodiments, each RACH configuration corresponds to an index 0, 1, 2...N.

[0374] In some embodiments, the network side may simultaneously configure multiple sets of RACH configurations that are activated by default. The set of RACH configurations that are activated by default may include multiple RACH configurations that are activated by default.

[0375] Alternatively, multiple RACH configurations also have the following characteristics:

[0376] Each RACH configuration is associated with a configuration of 64 preambles, that is, the preamble configuration is configured per RACH, or configured per RACH configuration group (that is, multiple RACH configurations are associated with one preamble configuration).

[0377] In some embodiments, the RACH configuration corresponds to the RACH configuration information in the foregoing embodiments.

[0378] Embodiment 1:

[0379] After the network side activates the RACH, the parameter for RO selection includes a random factor, for example, a random number between (0 to 1). The terminal randomly generates a random number random A.

[0380] Optionally, if A > factor, the activated RACH resource is selected; if A ≤ factor, the default activated RACH resource is selected.

[0381] Optionally, if A < factor, the activated RACH resource is selected; if A ≤ factor, the default activated RACH resource is selected.

[0382] In some embodiments, the activated RACH resource includes or corresponds to the RACH resource activated by the network device in the foregoing embodiments.

[0383] Embodiment 2:

[0384] If there are multiple default activated RACH resources or multiple activated RACH resources, each RACH resource is configured with a numerical interval, and the RACH resource associated with the numerical interval into which the random number random A generated by the terminal falls is selected.

[0385] Optionally, the interval of RACH configuration 5 is 0.3 to 0.5.

[0386] Embodiment 3:

[0387] If there are multiple default activated RACH resources or multiple activated RACH resources, selecting whether to use an activated RACH resource or a default activated RACH resource according to the solution in Embodiment 1, and then randomly select one from the selected RACH resources.

[0388] Optionally, after selecting an activated RACH resource according to the solution in Embodiment 1, randomly select one from multiple activated RACH resources.

[0389] Embodiment 4:

[0390] The network side is configured with an integer N, which is used to assist the terminal in selecting RACH resources.

[0391] In some embodiments, when initiating random access and not receiving a RAR or its own RAR, when selecting resources again, terminals with RA-RNTI mod N = 0, or preamble ID mod N = 0, continue to select the current RACH resource; terminals with RA-RNTI mod N ≠ 0, or preamble ID mod N ≠ 0, select other RACH resources, such as the active RACH resource. Here, mod represents the modulo operation.

[0392] In some embodiments, when selecting a resource again, a terminal with RA-RNTI mod N = 0 or a preamble ID mod N = 0 selects another RACH resource, such as the active RACH resource; a terminal with RA-RNTI mod N ≠ 0 or a preamble ID mod N ≠ 0 continues to select the current RACH resource.

[0393] In the above embodiments, load balancing is achieved based on the network-side configured values, the probability distribution of default RACH resource activation and RACH resource activation selection, and network control.

[0394] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0395] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0396] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0397] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0398] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
