[0018] The embodiments of the present disclosure provide an information processing method, a terminal, and a storage medium.

[0019] In a first aspect, an embodiment of the present disclosure proposes an information processing method, which is executed by a terminal, including: performing a first operation based on PRACH transmission cancellation; wherein performing the first operation includes one of the following: performing the next random access attempt of the random access process; and performing the RAR reception process.

[0020] In the above embodiments, the terminal's behavior after a PRACH transmission is canceled can be clarified. For example, after a PRACH transmission is canceled, the terminal can execute the next random access attempt, eliminating the need to execute the PRACH RAR procedure. This can reduce unnecessary power and / or resource waste at the terminal. For another example, after a PRACH transmission is canceled, it can be assumed that the preamble or MSGA for the PRACH transmission has already been sent, and the RAR reception procedure can be executed. This can reduce the possibility of missing a monitored RAR message.

[0021] In combination with some embodiments of the first aspect, in some embodiments, performing the next random access attempt of the random access procedure includes: re-executing the resource selection procedure of the random access.

[0022] In the above embodiment, the terminal re-executes the resource selection process of random access, so as to facilitate the terminal to perform the next random access; for example, it is convenient for the terminal to select appropriate resources to send the preamble and the like.

[0023] In combination with some embodiments of the first aspect, in some embodiments, PRACH transmission cancellation includes: the physical layer of the terminal does not send a preamble (Preamble); and / or the physical layer of the terminal does not send a first message (MSGA).

[0024] In the above embodiment, several situations of PRACH cancellation are clarified; for example, it may be that the preamble in the four-step random access is not actually sent, or that the MSGA in the random access is not actually sent.

[0025] In combination with some embodiments of the first aspect, in some embodiments, not sending the first message includes: not sending a preamble of the first message; and / or not sending a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) of the first message.

[0026] In the above embodiment, the specific content of the first message not sent is clarified; for example, it may be a preamble in a four-step random access (for example, carried in the MSG1 message); or it may be a four-step random access terminal PUSCH (carried in MSG4).

[0027] In combination with some embodiments of the first aspect, in some embodiments, the physical layer of the terminal does not send a preamble code, including: based on the terminal's media access control (MAC) layer instructing the physical layer to send a preamble code on a random access channel occasion (RACH occasion, PO), and the physical layer does not send a preamble code; and / or, the physical layer of the terminal does not send a first message, including: based on the terminal's MAC layer instructing the physical layer to send a first message on the PO, and the physical layer does not send the first message.

[0028] In the above embodiment, the reason why the physical layer of the terminal does not send the preamble code and / or the reason why the terminal does not send the first message is clarified.

[0029] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: determining PRACH transmission cancellation based on resource conflict; wherein the resource conflict includes: time domain and / or frequency domain resource conflict; and / or power resource conflict.

[0030] In the above embodiment, the terminal determines that the cancellation of PRACH transmission is due to resource conflict, for example, conflict with other reception and / or transmission in the time domain and / or frequency domain, or power limitation.

[0031] In combination with some embodiments of the first aspect, in some embodiments, the time domain and / or frequency domain resource conflict includes at least one of the following: a conflict between PRACH transmission and downlink reception; a time interval between PRACH transmission and downlink reception is less than or equal to a first time unit; wherein the first time unit includes: at least one symbol, at least one time slot and / or a first duration; a conflict between PRACH transmission and a downlink symbol; a conflict between PRACH transmission triggered by the MAC layer and a flexible symbol indicated by downlink control information (DCI); a conflict between PRACH transmission triggered by the radio resource control (RRC) layer and a flexible symbol indicated by the DCI; a conflict between PRACH transmission and a resource control set (CORESET), wherein the resources of the resource control set are not indicated as flexible symbols or uplink symbols; a conflict between PRACH transmission and undetected flexible symbols; a PRACH transmission and a transmission of the first channel are in the same time slot; wherein the first channel includes a physical uplink control channel (PUCCH); Channel, PUCCH) and / or PUSCH; PRACH transmission and scheduling request (SR) are in the same time slot; the time interval between PRACH transmission and transmission of the first channel is less than or equal to the first time unit; and the time interval between PRACH transmission and SR is less than or equal to the first time unit.

[0032] In the above embodiments, various situations in which PRACH transmission cancellation may be caused by time domain and / or frequency domain resource conflicts are provided, which can adapt to more application scenarios.

[0033] In combination with some embodiments of the first aspect, in some embodiments, the conflict between PRACH transmission and downlink reception includes one of the following: under time division duplex (TDD), the conflict between PRACH transmission and downlink reception; and under frequency division duplex (FDD), the conflict between PRACH transmission and downlink reception; and / or, the time interval between PRACH transmission and downlink reception is less than or equal to the first time unit, including one of the following: under TDD, the time interval between PRACH transmission and downlink reception is less than or equal to the first time unit; and under FDD, the time interval between PRACH transmission and downlink reception is less than or equal to the first time unit.

[0034] In the above embodiments, the conflict between PRACH transmission and downlink reception in the time domain and / or the conflict between PRACH transmission and downlink reception in the time domain and frequency domain is clarified.

[0035] In combination with some embodiments of the first aspect, in some embodiments, the power resource conflict includes: under dual connectivity (DC), the sum of the powers of the cells corresponding to the terminal is greater than the maximum transmit power; and / or, under carrier aggregation (CA), the sum of the powers of the cells corresponding to the terminal is greater than the maximum transmit power.

[0036] In the above embodiment, it is clarified that the cancellation of PRACH transmission is caused by power limitation; that is, if the sum of the power of each cell is greater than the maximum transmit power, there is no excess power for PRACH transmission, which may lead to the cancellation of PRACH transmission.

[0037] In combination with some embodiments of the first aspect, in some embodiments, executing the next random access attempt of the random access process includes: before selecting the random access resource, determining that the value of the first counter is added by 1; wherein the first counter includes: a preamble code transmission counter or a preamble code power increase counter.

[0038] In the above embodiment, before each random access attempt is re-executed, the value of the first counter needs to be increased by 1, so that the number of RACH transmission failures (or the number of preamble code transmission failures) can be recorded, thereby facilitating the subsequent determination of whether to continue the random access attempt.

[0039] In combination with some embodiments of the first aspect, in some embodiments, executing the next random access attempt of the random access procedure includes: executing the next random access attempt of the random access procedure based on the value of the first counter being less than or equal to a threshold.

[0040] In the above embodiment, the next random access attempt of the random access procedure is performed only when the value of the first counter is less than or equal to the threshold, thereby eliminating the need to always perform the next random access attempt and reducing unnecessary waste of power and / or resources of the terminal.

[0041] In combination with some embodiments of the first aspect, in some embodiments, the method further includes: determining a random access problem based on a value of the first counter being greater than a threshold.

[0042] In the above embodiment, when the value of the first counter reaches the threshold, that is, the maximum number of PRACH transmission retransmissions is reached, if the random access is still unsuccessful, the random access problem is determined and the random access is stopped, thereby reducing unnecessary power and / or resource waste of the terminal.

[0043] In combination with some embodiments of the first aspect, in some embodiments, determining a random access problem includes: based on whether the preamble code is sent on a special cell (SpCell), determining that the MAC layer sends indication information to the upper layer, wherein the indication information is used to indicate the random access problem; wherein the special cell includes a primary secondary cell (PsCell) and / or a secondary cell (SCell); and / or, based on whether the preamble code is sent on the secondary cell SCell, determining that the random access is not completed successfully.

[0044] In the above embodiment, when the preamble is sent in different cells, the manner of determining the random access problem is different.

[0045] In combination with some embodiments of the first aspect, in some embodiments, determining the random access problem based on the value of the first counter being greater than a threshold includes: determining the random access problem based on the value of the first counter being greater than the threshold and the RACH being triggered based on a system message request.

[0046] In the above embodiment, the terminal may request the base station to update the system information through a system message request. If the random access is not successful when the value of the first counter is greater than the threshold, it is determined that the random access problem has failed and the system information update request has failed.

[0047] In combination with some embodiments of the first aspect, in some embodiments, executing the next random access attempt of the random access process includes: before selecting the random access resource, determining that the value of the first counter remains unchanged; wherein the first counter includes: a preamble code transmission counter or a preamble code power increase counter.

[0048] In some embodiments, the value of the first counter may not be increased by 1 before each random access attempt is re-executed, so that the random access process can be performed as many times as possible, which is beneficial for the terminal to access the network.

[0049] In combination with some embodiments of the first aspect, in some embodiments, the random access response RAR reception process includes: based on the MAC layer indicating the physical layer to send a Preamble and the physical layer does not send a Preamble, executing the RAR reception process; and / or, based on the MAC layer indicating the physical layer to send a first message and the physical layer does not send the first message, executing the RAR reception process.

[0050] In some embodiments, when PRACH transmission is canceled, the possibility of missing the RAR message can be reduced by executing the RAR reception process; and the situation where the PRACH transmission is canceled due to the failure to actually send the preamble code or the first message and the RAR reception process is executed is clarified.

[0051] In the second aspect, an embodiment of the present disclosure proposes a terminal, comprising: a processing module, configured to perform a first operation based on PRACH transmission cancellation; wherein, performing the first operation includes one of the following: performing the next random access attempt of the random access process; and performing the RAR reception process.

[0052] In a third aspect, an embodiment of the present disclosure proposes a terminal, comprising: one or more processors; wherein the terminal is used to execute the optional implementation method of the first aspect.

[0053] In a fourth aspect, an embodiment of the present disclosure proposes a storage medium, which stores instructions. When the instructions are executed on a communication device, the communication device executes the method described in the optional implementation manner of the first aspect.

[0054] In a fifth aspect, an embodiment of the present disclosure proposes a program product. When the program product is executed by a communication device, the communication device executes the method described in the optional implementation manner of the first aspect.

[0055] In a sixth aspect, an embodiment of the present disclosure proposes a computer program, which, when executed on a computer, enables the computer to execute the information processing method as described in the optional implementation manner of the first aspect.

[0056] In a seventh aspect, an embodiment of the present disclosure proposes a chip or a chip system; the chip or chip system includes a processing circuit configured to execute the method described in the optional implementation manner of the above-mentioned first aspect.

[0081] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.

[0087] It can be understood that the information processing system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0088] The following embodiments of the present disclosure may be applied to the information processing system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The information processing system may include all or a portion of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities may be arbitrary. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0089] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0090] In some embodiments, the Random Access Channel (RACH) occasion (RO) is periodically configured. In paired spectrum, all ROs are valid ROs. In unpaired spectrum, the RO may overlap with the downlink symbol (DL symbol) or the synchronization signal block (SSB) in the time domain. Since the terminal and the base station can only perform downlink reception or transmission at the same time, or the terminal and the base station can only perform uplink transmission or reception at the same time, an RO validation mechanism is introduced. Optionally, the RACH occasion can be a PRACH occasion.

[0091] For example, when higher-layer signaling does not configure a cell-specific timeslot format, such as time-division dual-link uplink downlink common (tdd-UL-DL-ConfigurationCommon), in a PRACH timeslot, only the RO that follows the SSB and is separated from the SSB by N gap symbols can be considered a valid RO; N is an integer greater than 0. When higher-layer signaling configures tdd-UL-DL-ConfigurationCommon, a valid RO appears in uplink symbols (UL symbols) or after N gap symbols between the SSB and the DL symbol.

[0092] For example, after determining a valid RO, the valid RO can be mapped to the SSB. In some scenarios, only the valid RO mapped with the SSB can be used for PRACH transmission, and the valid RO not mapped with the SSB cannot be used for PRACH transmission.

[0093] In some embodiments, PRACH transmission conflict handling: After the physical layer determines a valid RO that can be used for PRACH transmission and receives a transmission indication from a higher layer, the actual PRACH transmission may be canceled due to a conflict between the PRACH transmission and transmissions on other channels. Exemplarily, the transmission indication from the higher layer includes instructing the physical layer to use the selected RACH timing, the corresponding Random Access Radio Network Temporary Identifier (RA-RNTI), the preamble index (PREAMBLE_INDEX) and / or the preamble received target power (PREAMBLE_RECEIVED_TARGET_POWER) to send the random access preamble.

[0094] In some embodiments, the collision between the PRACH transmission and other channel transmissions includes at least one of the following:

[0095] Case 1: Time Division Duplex (TDD) Band PRACH and Downlink Conflict Handling. Case 1 may include: overlapping between the Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), or Channel State Information Reference Signal (CSI-RS) and PRACH.

[0096] When the dynamic scheduling (DG) PDSCH and DG CSI-RS overlap with the PRACH in the time domain, the terminal determines whether to transmit the PRACH or to cancel the PRACH transmission and transmit the DG (dynamic grant) PDSCH and CSI-RS. This depends on the terminal implementation. In other words, the terminal may cancel the actual PRACH transmission.

[0097] When the PDCCH or SPS PDSCH or SPS CSI-RS overlaps with a valid RACH opportunity in the time domain, the terminal will cancel the transmission of the downlink PDCCH or SPS PDSCH or SPS CSI-RS.

[0098] In addition, the terminal does not expect the N interval symbols before the valid RACH timing and the valid PRACH time to be indicated as downlink symbols (DL symbol) by the cell-specific high-layer signaling tdd-UL-DL-ConfigurationCommon, the UE-specific high-layer signaling tdd-UL-DL-ConfigurationDedicated and / or the downlink control information format 2.0 (Downlink Control Information format 2-0, DCI format 2-0). For the downlink symbols indicated by the base station through cell-specific or UE-specific high-layer signaling, the terminal does not transmit PRACH. The terminal does not expect the control resource set (CORESET) corresponding to the type 0 common search space (CSS) to be indicated as an uplink symbol.

[0099] When the terminal monitors DCI format 2-0 (Slot Format Indication (SFI) indication) and a symbol is indicated as a flexible symbol, PDCCH ordered PRACH can be transmitted on it, but PRACH triggered by Media Access Control (MAC) or Radio Resource Control (RRC) cannot be transmitted.

[0100] For symbols occupied by the control resource set (CORESET), if SFI monitoring is configured but no uplink symbol or flexible symbol indication of SFI is detected, the symbol is considered to be a downlink symbol, and the terminal does not perform PDCCH scheduled PRACH transmission on it.

[0101] The terminal may perform PDCCH scheduled PRACH transmissions on flexible symbols where no SFI indication is detected. However, for MAC or RRC triggered PRACH transmissions, if the terminal is configured to listen for SFI indications (DCI format 2-0), the PRACH transmission is not canceled if the interval between the last symbol of the control resource set (CORESET) and the first symbol of the PRACH is less than T_process,2. Otherwise, the PRACH transmission is canceled.

[0102] Case 2: PRACH conflicts with other uplink channels or uplink reference signals. The terminal is not in the same timeslot, or the time gap between the PRACH transmission and other uplink channels, including PUCCH, PUSCH, and scheduling requests (SR), is less than N symbols. When this overlap occurs, the decision on which channel to transmit depends on the terminal implementation.

[0103] Case 3: PRACH transmission cancellation due to power allocation: In carrier aggregation (CA) or dual connectivity (DC) scenarios, PRACH transmission on a cell may be cancelled due to power allocation.

[0104] Case 4: Half-Frequency Division Duplex (HD-FDD) PRACH and DL conflict handling.

[0105] For HD-FDD terminals, only uplink transmission or downlink reception can be performed at a time, even though the base station operates in full-duplex mode. Given that a terminal can only perform uplink transmission or downlink reception at a time, similar to TDD bands, consideration must be given to resolving time-domain overlap between uplink PRACH transmissions (e.g., PRACH transmissions) and downlink transmissions.

[0106] There are several possible scenarios for overlap between PRACH transmission and downlink transmission:

[0107] In case 4.1, when the valid RO overlaps with the Type 0 / 0A / 1 / 2 CSS, the terminal decides whether to perform PRACH transmission or PDCCH reception.

[0108] In case 4.2, when the valid opportunity and UE-dedicated configured DL reception (UE-dedicated configured DL reception), such as User-Specific Search Space (USS) PDCCH, Semi-Persistent Scheduling (SPS) PDSCH, CSI-RS and / or Downlink Positioning Reference Signal (DL PRS), overlap in time domain, the terminal decides whether to perform PRACH transmission or semi-persistent downlink reception.

[0109] In case 4.3, when the effective opportunity overlaps with the DG PDSCH or CSI-RS, it is up to the terminal to determine whether to perform downlink reception or uplink transmission.

[0110] In case 4.4, when SSB and PRACH transmissions overlap, the terminal decides whether to perform downlink reception or uplink transmission.

[0111] In case 4.5, when the switch time gap between SSB or CSS PDCCH and RO cannot be guaranteed by scheduling, the terminal decides whether to cancel downlink reception or uplink transmission.

[0112] FIG2 is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2 , the present disclosure embodiment relates to an information processing method for an information processing system 100, and the method includes:

Here, the conflict between the PRACH transmission and the downlink symbol may be: the PRACH transmission overlaps the downlink symbol, or the symbol where the PRACH transmission is located is a downlink symbol.

[0124] Optionally, the DCI may be a DCI of format 2-0, for example, the DCI is DCI format 2-0. Optionally, the DCI may be a DCI of any format, or a predefined DCI, or a newly defined DCI, for example, DCI1, DCI2, or DCIX.

[0125] Optionally, the flexible symbol may be any symbol. Exemplarily, the flexible symbol may be defined as: neither an uplink symbol nor a downlink symbol.

[0126] Optionally, the conflict between the PRACH transmission triggered by the MAC layer and the flexible symbol indicated by the DCI includes: in the TDD frequency band, the conflict between the PRACH transmission triggered by the MAC layer and the flexible symbol indicated by the DCI.

Here, the conflict between a PRACH transmission and a resource control set may be: overlapping symbols occupied by the PRACH transmission and the resource control set; or, a time unit (e.g., symbol) of the PRACH transmission is the same as a time unit (e.g., symbol) occupied by the resource control set.

[0129] Exemplarily, a conflict between a PRACH transmission and a resource control set may be that the resources of the control resource set are not indicated by the DCI as flexible symbols or uplink symbols, where the resources of the control set are resources configured for transmitting the PDCCH.

[0142] In some optional embodiments, before step S2101, the terminal performs PRACH.

[0143] Step S2102: The terminal performs a first operation based on the PRACH transmission cancellation.

[0144] In some embodiments, performing the first operation includes: performing a next random access attempt of the random access procedure. Optionally, the first operation includes: re-performing the random access procedure.

[0145] In some embodiments, performing the first operation includes: performing a random access response (RAR) reception procedure.

[0146] Optionally, performing the next random access attempt of the random access procedure may include: re-executing the resource selection procedure of the random access.

[0147] Optionally, executing the next random access attempt of the random access procedure may include: from the start of the random access resource selection procedure to the end of the random access procedure. Exemplarily, for two-step random access, executing the next random access attempt of the random access procedure may include: from the start of the random access resource selection procedure to the completion of sending MSG1, or from the start of the random access resource selection procedure to the receipt of MSG2. Exemplarily, for four-step random access, executing the next random access attempt of the random access procedure may include: from the start of the random access resource selection procedure to any stage of sending MSG1 or MSG3, or from the start of the random access resource selection procedure to any stage of receiving MSG2 or MSG4. Exemplarily, executing the next random access attempt of the random access procedure may include: skipping the random access initialization step and executing random access.

[0148] In some embodiments, after the PRACH transmission is canceled and before performing the next random access attempt of the random access procedure, the terminal determines that the value of the first counter is increased by 1. Optionally, the terminal determines that the value of the first counter is increased by 1 before selecting a random access resource.

[0149] In some embodiments, the terminal performs a next random access attempt of the random access procedure based on the value of the first counter being less than or equal to a threshold.

[0150] Optionally, the first counter includes: a preamble transmission counter or a preamble power ramping counter. Exemplarily, the preamble transmission counter may be PREAMBLE_TRANSMISSION_COUNTER. Exemplarily, the preamble power ramping counter may be PREAMBLE_POWER_RAMPING_COUNTER.

[0151] Optionally, the threshold may be: the maximum number of preamble transmissions, or the maximum number of preamble transmissions plus 1. Optionally, the threshold may be predetermined by the terminal, specified by a protocol, or negotiated between the terminal and the network device. Exemplarily, if the initial value of the first counter is 1, the threshold may be the maximum number of preamble transmissions plus 1; alternatively, if the initial value of the first counter is 0, the threshold may be the maximum number of preamble transmissions.

[0152] Exemplarily, before the terminal performs the next random access attempt of the random access process, the terminal determines that the value of the first counter is increased by 1; if the terminal determines that the first counter after increasing by 1 is less than or equal to the threshold, the terminal performs the next random access attempt of the random access process.

[0153] In some embodiments, after the terminal cancels PRACH transmission and before performing the next random access attempt of the random access procedure, the terminal determines that the first counter remains unchanged. Optionally, before selecting a random access resource, the terminal determines that the value of the first counter remains unchanged. In this way, the value of the first counter can also be maintained unchanged during the next random access attempt of the random access procedure, so that the terminal can make as many random access attempts as possible.

[0154] Exemplarily, before the terminal performs the next random access attempt of the random access procedure, it determines that the value of the first counter remains unchanged; if the terminal determines that the first counter is less than or equal to the threshold, it performs the next random access attempt of the random access procedure.

[0155] In some embodiments, the terminal determines not to perform the next random access attempt of the random access procedure based on the value of the first counter being greater than a threshold, or determines not to perform the random access procedure within a predetermined time.

[0156] Exemplarily, before the terminal performs the next random access attempt of the random access process, the terminal determines that the value of the first counter is increased by 1; if the terminal determines that the first counter after increasing by 1 is greater than the threshold, the terminal determines not to perform the next random access attempt of the random access process.

[0157] Exemplarily, before the terminal performs the next random access attempt of the random access procedure, it determines that the value of the first counter remains unchanged; if the terminal determines that the first counter is greater than the threshold, it determines not to perform the next random access attempt of the random access procedure.

[0158] In some embodiments, the terminal performs the RAR reception process based on the MAC layer instructing the physical layer to send the Preamble and the physical layer does not send the Preamble.

[0159] In some embodiments, the terminal performs the RAR reception process based on the MAC layer instructing the physical layer to send the first message and the physical layer not sending the first message.

[0160] Step S2103: The terminal determines a random access problem.

[0161] In some optional embodiments, the terminal determines a random access problem based on PRACH cancellation.

[0162] In some embodiments, the terminal determines the random access problem based on the value of the first counter being greater than a threshold.

[0163] Optionally, the terminal determines that the MAC layer sends indication information to a higher layer based on whether the preamble is sent on a special cell (SpCell), where the indication information is used to indicate a random access problem; the special cell includes a primary or secondary cell (PsCell) and / or a secondary cell (SCell). Optionally, the higher layer may be an RRC layer.

[0164] For example, before the terminal performs the next random access attempt of the random access procedure, the terminal determines that the value of the first counter is incremented by 1; if the terminal determines that the incremented first counter is greater than a threshold, the terminal determines that a random access problem has occurred. For example, if the preamble is sent on a special cell, an indication message may be sent to a higher layer via the MAC to inform the higher layer of the occurrence of the random access problem.

[0165] For example, before the terminal performs the next random access attempt of the random access procedure, it is determined that the value of the first counter remains unchanged; if the terminal determines that the first counter is greater than the threshold, a random access problem is determined. For example, if the preamble is sent in a special cell, an indication message can be sent to a higher layer via MAC to inform the higher layer of the occurrence of a random access problem.

[0166] Optionally, the terminal determines that the random access is not successfully completed based on whether the preamble is sent on a secondary cell (SCell). Here, determining that the random access is not successfully completed means determining a random access problem.

[0167] For example, before the terminal performs the next random access attempt of the random access procedure, the terminal determines that the value of the first counter is incremented by 1; if the terminal determines that the incremented first counter is greater than a threshold, the terminal determines that a random access problem occurred. For example, if the preamble is sent on the secondary cell, the terminal may determine that the random access was not successfully completed.

[0168] For example, before the terminal performs the next random access attempt of the random access procedure, the terminal determines that the value of the first counter remains unchanged; if the terminal determines that the first counter is greater than a threshold, the terminal determines that a random access problem occurred. For example, if the preamble is sent in the secondary cell, the terminal may determine that the random access was not successfully completed.

[0169] Optionally, the terminal determines the random access problem based on that a value of the first counter is greater than a threshold and RACH is triggered based on a system message request.

[0170] Exemplarily, before the terminal performs the next random access attempt of the random access process, it determines that the value of the first counter is increased by 1; if the terminal determines that the first counter after increasing by 1 is greater than the threshold, and the random access (PRACH or RACH) is triggered by a system message request, a random access problem is determined.

[0171] Exemplarily, before the terminal performs the next random access attempt of the random access process, it is determined that the value of the first counter remains unchanged; if the terminal determines that the first counter is greater than the threshold and the random access (PRACH or RACH) is triggered by a system message request, a random access problem is determined.

[0172] In some optional embodiments, the random access in the embodiments of the present disclosure may include: PRACH and / or RACH. Optionally, PRACH may have one more step than RACH: the physical layer receives a transmission indication from a higher layer. For example, PRACH may include: the physical layer of the terminal receives a transmission indication from a higher layer, sends MSG1, and receives MSG2; RACH may include: sending MSG1 and receiving MSG2. For another example, PRACH may include: the physical layer of the terminal receives a transmission indication from a higher layer, sends MSG1, receives MSG2, sends MSG3, and receives MSG4; RACH may include: sending MSG1, receiving MSG2, sending MSG3, and receiving MSG4.

[0213] The above embodiments may be implemented individually or in combination with each other. For optional implementations, please refer to the optional implementations of the steps in FIG. 2 and FIG. 3A , which will not be described in detail here.

[0214] The present disclosure relates to an information processing method, which includes:

[0215] In some embodiments, the terminal initiates a random access procedure, and the MAC layer of the terminal instructs the physical layer to send a Preamble or MsgA on the selected RO; if the physical layer of the terminal fails to actually send the Preamble / MsgA, the terminal re-executes the RACH resource selection procedure or the random access response reception procedure. Optionally, the terminal may be a UE.

[0216] Optionally, the failure to send MsgA includes the failure to send the Preamble and / or PUSCH of MsgA.

[0217] Optionally, the failure to send the Preamble or MsgA is not due to a listen before talk (LBT) failure, but may be caused by at least one of the following reasons: a PRACH transmission conflicts with other transmissions and / or receptions in the time domain and / or frequency domain; or a PRACH transmission conflicts with other transmissions and / or receptions in the power domain. Exemplarily, the terminal cannot simultaneously send the Preamble or MsgA and other transmissions and / or receptions due to power limitations.

[0218] In some embodiments, when the physical layer of the terminal receives a transmission instruction from a higher layer, but actual transmission on the selected valid RO is canceled due to resource conflict, the physical layer of the terminal indicates the actual transmission cancellation instruction to the higher layer.

[0219] Optionally, the situation where actual PRACH transmission is canceled due to resource conflict includes at least one of the following:

[0220] Case 1: In the TDD band, PRACH transmission is canceled when a conflict occurs between the PRACH and downlink reception or the time interval between the PRACH and downlink reception does not meet N symbols. The time interval between the PRACH and downlink reception does not meet N symbols can be: the time interval between the PRACH and downlink reception is less than or equal to N symbols, where N is a positive integer.

[0221] Case 2: In the TDD band, the PRACH conflicts with the downlink symbols, resulting in the cancellation of the PRACH transmission.

[0222] Case 3: In the TDD band, the PRACH transmission is canceled due to a conflict between the PRACH triggered by MAC or RRC and the flexible symbols indicated by DCI format 2-0.

[0223] Case 4: In the TDD band, the terminal is configured to monitor DCI format 2-0, but the terminal does not detect that the symbols occupied by the control resource set CORESET are indicated by DCI format 2-0 as uplink symbols or flexible symbols; in this case, there is a time domain conflict between CORESET and PRACH, resulting in cancellation of PRACH transmission.

[0224] Case 5: In the TDD band, the terminal is configured to monitor DCI format 2-0, but because the terminal does not detect the PRACH transmission scheduled by the PDCCH on the flexible symbols indicated by DCI format 2-0, a time domain conflict occurs between some flexible symbols and the PRACH time (PO); in this case, the PRACH transmission is canceled. Optionally, for PRACH transmission triggered by MAC or RRC, if the terminal is configured to monitor the SFI indication, when the interval between the last symbol of the CORESET used to monitor the SFI indication and the first symbol of the PRACH is less than T_process,2, the PRACH transmission is not canceled; otherwise, the PRACH transmission is canceled.

[0225] Case 6: In any spectrum, when the transmission between PRACH and other uplink channels (such as PUCCH, PUSCH and SR) is in the same time slot, or the time interval between PRACH and other uplink channels is less than or equal to N symbols, the PRACH transmission is canceled.

[0226] Case 7: In the CA or DC scenario, since the sum of the power on each cell is greater than the maximum transmit power (PCmax), the PRACH transmission caused by further power allocation is canceled.

[0227] Case 8: For HD-FDD terminals, when PRACH transmission conflicts with other downlink reception, or the time interval between PRACH and other downlink reception does not meet N symbols, the PRACH transmission is canceled. Optionally, other downlink reception refers to downlink reception other than PRACH transmission.

[0228] Optionally, the resource conflict may be a time domain and / or frequency domain resource conflict, or a power resource conflict in the previous embodiment; here, Case 1, Case 2, Case 3, Case 4, Case 5, Case 6 and Case 8 are time domain and / or frequency domain resource conflicts in the previous embodiment; Case 7 is a power resource conflict in the previous embodiment.

[0229] In some embodiments, the terminal re-executes the RACH resource selection process, including, before performing RACH resource selection, adding 1 to PREAMBLE_TRANSMISSION_COUNTER. Optionally, PREAMBLE_TRANSMISSION_COUNTER is the preamble transmission counter in the previous embodiment.

[0230] Optionally, after PREAMBLE_TRANSMISSION_COUNTER is incremented by 1, if PREAMBLE_TRANSMISSION_COUNTER=preambleTransMax+1, the terminal MAC layer indicates a random access problem to upper layers. Optionally, preambleTransMax is the maximum number of preamble transmissions in the previous embodiment.

[0231] Exemplarily, if the preamble is to be sent on the SpCell, the MAC layer of the terminal indicates a random access problem to higher layers.

[0232] Exemplarily, if the preamble is to be sent on the SCell, the terminal considers that the random access is not completed successfully (ie, completed, but not successfully completed).

[0233] Optionally, after PREAMBLE_TRANSMISSION_COUNTER is incremented by 1, if PREAMBLE_TRANSMISSION_COUNTER=preambleTransMax+1, and if the random access is triggered by a system message request, the terminal considers that the random access is unsuccessfully completed.

[0234] Optionally, the terminal performs RACH resource selection only when it is determined that the random access is not completed.

[0235] In some embodiments: the terminal re-executes the RACH resource selection process, including: before performing the RACH resource selection, PREAMBLE_TRANSMISSION_COUNTER is not increased by 1 (ie, remains unchanged).

[0236] In some embodiments, the terminal re-executes the RACH resource selection process, including: before performing RACH resource selection, PREAMBLE_POWER_RAMPING_COUNTER is not increased by 1 (ie, remains unchanged). Optionally, PREAMBLE_POWER_RAMPING_COUNTER can be the preamble power ramping counter in the previous embodiment.

[0237] In some embodiments, the terminal performs the random access response receiving procedure, including: the terminal assumes that the Preamble or MsgA indicated by the MAC layer to the physical layer has been sent; and the terminal performs the random access response receiving procedure accordingly.
