Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and particularly relates to an information transmission method and device, electronic equipment and computer program product. BACKGROUND

[0002] In a sub-band non-overlapping full duplex (SBFD) system, when random access is performed using the resources of an uplink sub-band (see Figure 3 ), if both legacy terminal devices (legacy UEs, which do not support SBFD sub-band configuration, and can also be referred to as non-SBFD UEs) and SBFD terminal devices (which support SBFD sub-band configuration) can send a physical random access channel (PRACH) in the uplink symbol (i.e. the yellow area in Figure 3 ), then according to the existing mechanism of random access radio network temporary identity (RA-RNTI) design, the two types of UEs that select the same random access resource or occasion (RO) and preamble index will detect the same random access response (RAR), and the RAR carries the uplink grant (UL grant) of Msg 3. If the uplink grant indicates that the SBFD UE transmits Msg 3 on the downlink symbol, this will cause the legacy UE to be unable to interpret or recognize the content of the UL grant carried in the RAR, and thus will be unable to send Msg 3.

[0035] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0036] The technical solutions of this disclosure can be applied to various communication systems, such as 5th generation (5G), new radio (NR), long term evolution (LTE), Internet of Things (IoT), wireless-fidelity (WiFi), wireless communication related to the 3rd generation partnership project (3GPP), or other wireless communication that may emerge in the future.

[0037] First, refer to Figure 1 Overview of application scenarios according to embodiments of this disclosure.

[0038] Figure 1 This is a schematic diagram illustrating an application scenario of the information transmission method according to an embodiment of the present disclosure. For example... Figure 1 As shown, the application scenario includes at least two devices: terminal device 10 and network device 20. The network device 20 and terminal device 10 can communicate via a wireless link to exchange information.

[0039] Among them, network device 20 is a network-side device with wireless transceiver capabilities. The network device can be a device in a radio access network (RAN) that provides wireless communication functions for terminal devices, referred to as RAN equipment. For example, the network device can be a base station, an evolved NodeB (eNodeB), a next-generation NodeB (gNB) in a 5G mobile communication system, a 3GPP subsequent evolution base station, a transmission reception point (TRP), an access node in a WiFi system, a wireless relay node, a wireless backhaul node, etc. In communication systems employing different radio access technologies (RATs), the name of the device with base station functionality may differ. For example, in an LTE system, it may be called an eNB or eNodeB, and in a 5G or NR system, it may be called a gNB. This application does not limit the specific name of the base station. The network device can include one or more co-located or non-co-located transmission and reception points. Furthermore, the network device can include one or more central units (CUs), one or more distributed units (DUs), or one or more CUs and one or more DUs. For example, the functionality of a CU can be implemented by one entity or different entities. For instance, the CU's functionality can be further divided, separating the control plane and user plane and implementing them through different entities: a control plane CU entity (i.e., the CU-CP entity) and a user plane CU entity (i.e., the CU-UP entity). The CU-CP and CU-UP entities can be coupled with a DU to jointly complete the access network device's functionality. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU is responsible for handling physical layer protocols and real-time services, implementing the functions of the radio link control (RLC) layer, media access control (MAC) layer, and physical (PHY) layer. In this way, some functions of a wireless access network device can be implemented through multiple network function entities. These network function entities can be network elements in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform). The network device can also include an active antenna unit (AAU).The AAU implements some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since the information in the RRC layer ultimately becomes, or is derived from, PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can also be considered as being sent by the DU, or by the DU+AAU. It is understood that network devices can be one or more of the following: CU nodes, DU nodes, and AAU nodes. Furthermore, the CU can be classified as a network device in the radio access network (RAN) or a network device in the core network (CN); this application does not limit this. For example, in vehicle-to-everything (V2X) technology, the access network device can be a roadside unit (RSU). Multiple access network devices in a communication system can be base stations of the same type or different types. Base stations can communicate with terminal devices directly or through relay stations. In this embodiment, the device for implementing the network device function can be the network device itself, or it can be a device that supports the network device in implementing the function, such as a chip system or a combination of devices or components that can implement the access network device function. This device can be installed in the network device. In this embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices.

[0040] Terminal device 10 is a user-side device with wireless transceiver capabilities. It can be a fixed device, mobile device, handheld device (e.g., mobile phone), wearable device, in-vehicle device, or a wireless device (e.g., communication module, modem, or chip system) built into the aforementioned devices. Terminal devices are used to connect people, objects, and machines, and can be widely used in various scenarios, such as: cellular communication, device-to-device (D2D) communication, V2X communication, machine-to-machine / machine-type communications (M2M / MTC) communication, the Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical care, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, drones, robots, and other scenarios. For example, a terminal device can be a handheld terminal in cellular communication, a communication device in D2D, an IoT device in MTC, a surveillance camera in intelligent transportation and smart cities, or a communication device on a drone, etc. Terminal devices are sometimes referred to as user equipment (UE), user terminal, user device, user unit, user station, terminal, access terminal, access station, UE station, remote station, mobile device, or wireless communication device, etc. In the embodiments of this application, the device used to implement the functions of the terminal device can be the terminal device itself, or it can be a device capable of supporting the terminal device in implementing that function, such as a chip system or a combination of devices or components capable of implementing the functions of the terminal device. This device can be installed in the terminal device.

[0041] Furthermore, based on the spectral efficiency and full-duplex communication capability of the terminal device 10, the terminal device 10 in this disclosure can be divided into two categories: Subband Non-overlapping Full Duplex (SBFD) UE and Legacy UE (or non-SBFD UE).

[0042] Among them, SBFD UEs support non-overlapping sub-band full-duplex, meaning that SBFD UEs can recognize the configuration information of the SBFD uplink and downlink sub-bands configured by the network, and can transmit uplink in the SBFD uplink sub-band or receive downlink in the SBFD downlink sub-band on the downlink symbols configured by TDD. Legacy UEs do not support non-overlapping sub-band full-duplex, meaning they cannot recognize the configuration information of the SBFD uplink and downlink sub-bands configured by the network. In other words, Legacy UEs can only receive downlink on the downlink symbols configured by TDD and transmit uplink on the uplink symbols configured by TDD (see [link to details]). Figure 3 (To be further described).

[0043] Figure 2 This is a flowchart illustrating the random access process in existing technologies. Figure 2 (A) in the diagram is a flowchart of the four-step random access process. Figure 2 (B) in the diagram is a flowchart of the two-step random access process.

[0044] like Figure 2 As shown in (A), the 4-step random access process can include the following four steps:

[0045] Step 1: Terminal device 10 sends Msg 1.

[0046] Terminal device 10 sends Msg 1 to network device 20 to inform network device 20 that terminal device 10 has initiated a random access request. Msg 1 carries a Random Access Preamble (RAP), also known as a random access preamble or preamble. Simultaneously, Msg 1 can also be used by network device 20 to estimate the transmission delay between itself and terminal device 10 and to calibrate the uplink time accordingly.

[0047] Step 2, network device 20 sends Msg 2.

[0048] After receiving Msg 1 from terminal device 10, network device 20 sends Msg 2, a Random Access Response (RAR) message, to the terminal device. This Msg 2 can be scrambled using a Random Access Radio Network Temporary Identity (RA-RNTI). Terminal device 10 can listen on the Physical Downlink Control Channel (PDCCH) within the RAR window to receive RAR messages scrambled with the RA-RNTI.

[0049] If terminal device 10 does not receive a RAR message from network device 20 within the RAR window, it considers the random access to have failed. If terminal device 10 successfully receives a RAR message within the RAR window, and the index of the preamble carried in the RAR message is the same as the index of the preamble in Msg 1 sent by terminal device 10, then terminal device 10 can stop listening for RAR messages. Terminal device 10 uses RA-RNTI to descramble the RAR message.

[0050] Specifically, RNTI stands for Radio Network Temporary Identifier. The 5G system defines and uses numerous RNTIs to perform different functions, but the basic principle is to use the RNTI to scramble the CRC portion of the radio channel information. Then, the terminal device 10 uses the corresponding RNTI to search in the Common Search Space (CSS) or the User-Specific Search Space (USS), descrambles and obtains control information, and then obtains the corresponding resources from the PDSCH.

[0051] RA-RNTI is the RNTI used for preamble transmission, and its format is defined in the specification text as follows: RA-RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × ul_carrier_id.

[0052] Where s_id is the index of the first Orthogonal Frequency Division Multiplexing (OFDM) symbol used by PRACH, with a value range of 0 ≤ s_id < 14; t_id is the index of the first slot used by PRACH within each system frame, with a value range of 0 ≤ t_id < 80; f_id is the frequency domain resource index used by PRACH, with a value range of 0 ≤ f_id < 8; and ul_carrier_id is the uplink carrier used by msg1, with a value of 0 indicating a NUL carrier and a value of 1 indicating the use of a SUL carrier.

[0053] The RAR message may include corresponding messages for multiple terminal devices 10 that send preambles. The response message for each terminal device 10 includes the index (RAPID) of the preamble used by the terminal device 10, resource allocation information of Msg 3, time advance (TA) adjustment information, and Temporary Cell-Radio Network Temporary Identity (TC-RNTI).

[0054] In the NR standard, RAR messages can be scheduled using Downlink Control Information (DCI) format 1-0, and the PDCCH that schedules the RAR message can be scrambled using the aforementioned RA-RNTI.

[0055] Step 3: Terminal device 10 sends Msg 3.

[0056] After receiving a RAR message, terminal device 10 determines whether the RAR message belongs to it. For example, terminal device 10 can use a preamble identifier for verification. After confirming that it is a RAR message belonging to it, terminal device 10 generates Msg 3 at the RRC layer and sends Msg 3 to network device 20. Msg 3 needs to carry the identification information of terminal device 10, etc.

[0057] Step 4, network device 20 sends Msg 4.

[0058] Network device 20 sends Msg 4 to terminal device 10, and terminal device 10 correctly receives Msg 4 to complete the contention resolution. For example, during the establishment of an RRC connection, Msg 4 can carry an RRC connection establishment message.

[0059] In a 5G system, when performing random access, terminal device 10 can use either the aforementioned four-step random access method or a two-step random access method. One possible approach is to send Msg 1 and Msg 3 from the four-step random access process as the first message in the two-step random access process; and to send Msg 2 and Msg 4 from the four-step random access process as the second message in the two-step random access process. For details, please refer to [link to relevant documentation]. Figure 2 (B) will be described further.

[0060] like Figure 2 As shown in (B), the two-step random access process can include the following two steps:

[0061] Step 1': Terminal device 10 sends the first message (i.e., new Msg 1).

[0062] The new Msg 1 may include a preamble and uplink data. This uplink data may be carried on an uplink channel, such as the Physical Uplink Shared Channel (PUSCH). This uplink channel may carry, for example, the identification information of the terminal device and the reason for the RRC request. This new Msg 1 is similar to some or all of the information carried in Msg 1 and Msg 3 during the four-step random access procedure.

[0063] Step 2': The network device sends the second message (i.e., the new Msg 2).

[0064] If network device 20 successfully receives the first message sent by terminal device 10, it sends a new Msg 2 to terminal device 10. This new Msg 2 may include, for example, conflict resolution information, C-RNTI allocation information, TA adjustment information, etc. This second message is similar to some or all of the information carried in Msg 2 and Msg 4 during the four-step random access process.

[0065] During the two-step random access process, the new Msg 2 carries conflict resolution information for a single terminal device (including information related to the identifier of terminal device 10 sent by terminal device 10 in the new Msg 1), C-RNTI allocation information, TA adjustment information, etc. In addition, the new Msg 2 may also carry RRC resume messages, etc.

[0066] It should be noted that the new Msg 1 sent in the 2-step random access process usually includes a preamble and the uplink data portion, such as the content carried by Msg 3 in the 4-step random access process, in order to shorten the random access latency.

[0067] However, in some situations, such as poor channel quality or interference caused by other terminal devices initiating random access, network device 20 may not detect the new Msg 1 sent by terminal device 10. In this case, repeatedly retransmitting the new Msg 1 by terminal device 10 is inefficient for both terminal device 10 and network device 20. For terminal device 10, each transmission of a new Msg 1 means the simultaneous transmission of the preamble and data portion. Compared to the Msg 1 in the four-step random access process, the power consumed by terminal device 10 in transmitting the first message in the two-step random access process is far greater than the power consumed by transmitting only the preamble. On the other hand, for network device 20, the simultaneous transmission of the preamble and data portion means increased air interface interference, which will interfere with the transmission of new Msg 1 by other terminal devices 10.

[0068] Figure 3 This is a schematic diagram illustrating the configuration of the RO within a prior art SBFD system. For example...Figure 3 As shown, the horizontal axis represents the time domain (taking time slots #0 (or slot #0) to #4 in the figure as an example), and the vertical axis represents the frequency domain. Time slots #0 and #4 are the time slots for non-SBFD symbols (i.e., symbols without SBFD subbands), while time slots #1, #2, and #3 are the time slots for SBFD symbols; "D" represents downlink transmission (i.e., the green area), and "U" represents uplink transmission (i.e., the yellow area).

[0069] Specifically, non-SBFD time slot #0 can only be used for downlink transmission; SBFD time slots #1, #2, and #3 can be used for both uplink and downlink transmission (the yellow area can be understood as the uplink subband (UL subband)); non-SBFD time slot #4 can only be used for uplink transmission.

[0070] In other words, within the SBFD system, UL subbands can be configured in downlink time slots (e.g., time slot #1, time slot #2, time slot #3) for uplink transmission, reducing uplink latency and increasing uplink throughput.

[0071] Furthermore, UL subband resources can be utilized for random access (RACH), including the transmission of PRACH and Msg3. Specifically, based on the symbol type (SBFD symbol or non-SBFD symbol) and transmission direction (uplink or downlink) of time slots #0 to #4, the resources in time slots #0 and #4 are valid random access resources or opportunities (RACH Occasion, RO) for non-SBFD UEs, while the resources in time slots #1, #2, and #3 are valid ROs for SBFD UEs (or invalid ROs for non-SBFD UEs). Figure 3 The blue dashed box in the image exemplifies the traditional RO configuration used to configure random access resources for legacy UEs, while the red dashed box exemplifies the additional RO configuration used to configure random access resources for SBFD UEs.

[0072] Both legacy UEs and SBFD UEs can send PRACH on the UL symbol (uplink symbol) (i.e., the yellow area in the diagram).

[0073] As mentioned above, SBFD UEs can be scheduled in the UL subband of the SBFD slot (i.e., resources in slots #1, #2, and #3 are valid ROs for SBFD UEs), but legacy UEs cannot be scheduled in the UL subband of the SBFD slot (i.e., resources in slots #1, #2, and #3 are invalid ROs for non-SBFD UEs). If both the SBFD UE and the legacy UE send PRACH in slot #4, then according to the existing RA-RNTI design mechanism, the RA-RNTIs of the two types of UEs with the same RO index (selecting the same RO index in both the traditional RO configuration and the supplementary RO configuration respectively) and preamble index (same s_id, same t_id, and same f_id) will be the same, and the same RAR will be detected. The RAR carries the uplink grant (UL grant) of Msg 3, where UL... The grant is used by terminal device 10 to determine its PUSCH transmission parameters in Msg3, including but not limited to selecting appropriate time-domain or frequency-domain resources, modulation scheme, coding scheme, etc., to ensure that data can be correctly transmitted according to the requirements of network device 20. However, the uplink resources that legacy UEs and SBFD UEs can schedule are different, which will cause legacy UEs to be unable to interpret or recognize the content of the UL grant carried in the RAR, and thus be unable to transmit Msg3. To solve the above problem, the information transmission method of this disclosure is proposed. See below for details. Figures 4-5 Provide a detailed description.

[0074] Figure 4 This is a flowchart illustrating an information transmission method according to an embodiment of the present disclosure. Figure 4 As shown, the information transmission method applied to network device 20 may include at least the following steps.

[0075] In step S401, a random access response message is sent to the terminal device. The cyclic redundancy check (CRC) of the physical downlink control channel (PDCCH) that schedules the random access response message (RAR) is scrambled by a first-type radio network temporary identifier (RNTI) or a second-type RNTI. The types of terminal devices include: first-type terminal devices and / or second-type terminal devices, where first-type terminal devices correspond to first-type RNTIs and / or second-type RNTIs, and second-type terminal devices correspond to second-type RNTIs. First-type terminal devices can support subband non-overlapping full-duplex (SBFD) mode or support uplink frequency domain resource configuration information for downlink symbols, flexible symbols, or time slots; second-type terminal devices cannot support SBFD mode or support uplink frequency domain resource configuration information for downlink symbols, flexible symbols, or time slots.

[0076] As described above, this disclosure aims to address the problem that when SBFD UEs and non-SBFD UEs select the same RO index and preamble index in the same time slot, they will detect the same RAR. Because the RARs cannot be distinguished, different optimized scheduling cannot be performed for SBFD UEs and non-SBFD UEs. Therefore, to distinguish RARs, this disclosure proposes to scramble the CRC of the PDCCH of the RAR using either a first-type RNTI or a second-type RNTI. The first-type RNTI corresponds only to first-type terminal devices (e.g., SBFD UEs), while the second-type RNTI can correspond to either first-type or second-type terminal devices (e.g., non-SBFD UEs).

[0077] The first type of RNTI is determined based on specific rules, while the second type of RNTI can be understood as the aforementioned RA-RNTI. It should be noted that, for the purpose of differentiation, the first type of RNTI is different from the second type of RNTI.

[0078] As mentioned above, the random access procedure can be divided into 4-step random access and 2-step random access. It should be noted that the first type of RNTI and the second type of RNTI mentioned above correspond to the same random access procedure type (that is, the first type of RNTI and the second type of RNTI appear simultaneously in 4-step random access and / or the first type of RNTI and the second type of RNTI appear simultaneously in 2-step random access).

[0079] Figure 5 This is a further illustration of a method flowchart for an information transmission method according to an embodiment of the present disclosure. For example... Figure 5 As shown, the information transmission method applied to the terminal device 10 may include at least the following steps.

[0080] In step S501, a random access response message sent by a network device is received. The CRC of the PDCCH that schedules the random access response message is scrambled by either a first-type RNTI or a second-type RNTI. The first-type terminal device corresponds to both the first-type RNTI and / or the second-type RNTI, and the second-type terminal device corresponds to the second-type RNTI. This step can be understood as the opposite step of step S401, and its details will not be elaborated further.

[0081] In addition, the information transmission method applied to the terminal device 10 may include:

[0082] Detect the DCI format scrambled by CRC using Type I RNTI or Type II RNTI, receive the random access response message scheduled by DCI, and send PUSCH to network device 20 according to the uplink grant (UL grant) of the random access response (RAR).

[0083] It should be noted that when terminal device 10 is a type 1 terminal device, if it transmits PRACH using the first random access resource, it detects the PDCCH scrambled with a CRC by the type 1 RNTI; if it transmits PRACH using the second random access resource, it detects the PDCCH scrambled with a CRC by the type 2 RNTI. Here, the first random access resource can be understood as... Figure 3 The additional RO configuration in the middle, the second random access resource can be understood as Figure 3 The traditional RO configuration in the system.

[0084] The RAR UL grant includes: the first uplink grant (first UL grant) and / or the second uplink grant (second UL grant).

[0085] Specifically, the first UL grant is used to instruct a first type of terminal device (e.g., SBFD UE) to send PUSCH using the first time domain resources and the first frequency domain resources; the second UL grant is used to instruct a second type of terminal device (e.g., non-SBFD UE) to send PUSCH using the second time domain resources and the second frequency domain resources.

[0086] Furthermore, the first time-domain resources include downlink symbols or time slots configured with uplink frequency-domain resources, or flexible symbols or time slots;

[0087] The first frequency domain resource is the frequency offset value of frequency domain resources and / or physical uplink shared channel (PUSCH) frequency hopping, determined based on the size of the first type of frequency domain resources. The first type of frequency domain resources includes at least one of the following: uplink frequency domain resources, the initial uplink bandwidth portion (BWP) dedicated to the first type of terminal equipment, and the resource intersection of uplink frequency domain resources and the initial uplink BWP.

[0088] The second time-domain resource includes uplink symbols or time slots, or flexible symbols or time slots without configured uplink frequency-domain resources;

[0089] The second frequency domain resource is the frequency domain resource determined based on the size of the second type of frequency domain resource and the frequency offset value of the Physical Uplink Shared Channel (PUSCH). The second type of frequency domain resource includes the initial uplink BWP dedicated to the second type of terminal equipment.

[0090] This concludes the description of the information transmission method according to the embodiments of this disclosure. The information transmission method of this disclosure will now be described in further detail in conjunction with 4-step random access and 2-step random access.

[0091] I. Four-step random access:

[0092] Since the information transmission method of this embodiment is an improvement on Msg 2 and Msg 3, Msg 1 and Msg 4 will not be described again.

[0093] (1) Msg2:

[0094] When terminal device 10 is an SBFD UE, or a UE with resources (uplink subband) for uplink frequency domain transmission in downlink / flexible time slot / symbol configuration, it receives RAR and detects the DCI format scrambled by CRC with type 1 RNTI.

[0095] In one embodiment of this disclosure, the first type of RNTI is:

[0096] The first type of RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × 4

[0097] Where s_id is the index of the first OFDM symbol of the PRACH occasion within a slot (0≤s_id<14); t_id is the index of the first slot of the PRACH occasion within a system frame (0≤t_id<80); and f_id is the index of the PRACH occasion in the frequency domain (0≤f_id<8).

[0098] (2) Msg 3:

[0099] As described above, the RAR carries a UL grant, which indicates the time-domain and frequency-domain resources for transmitting the PUSCH. Specifically, the terminal device 10 transmits the PUSCH according to the UL grant, wherein the frequency-domain resources for the PUSCH are allocated as follows:

[0100] A) If the time-domain resource of PUSCH indicated in the RAR UL grant is a Type I symbol / slot (SBFD symbol / slot), where the Type I symbol / slot is a downlink or flexible symbol / slot configured with uplink frequency domain transmission resources (uplink subband).

[0101] A-1) Determine the frequency domain resource allocation based on the size of the first frequency domain resource. For example, the bits for the frequency domain resource allocation indication are... N1 is the size of the first frequency domain resource. The first frequency domain resource is either the uplink frequency domain transmission resource (uplink subband), the terminal-specific initial uplink BWP, or the intersection of the uplink frequency domain transmission resource (uplink subband) and the initial uplink BWP.

[0102] A-2) Determine the frequency offset value of PUSCH frequency hopping based on the size of the first frequency domain resource. For example, the frequency offset value of the second hop is... wait.

[0103] B) If the time-domain resource of the PUSCH indicated in the RAR UL grant is a Type II symbol / slot (non-SBFD symbol / slot), where the Type II symbol / slot is an uplink symbol / slot, or a flexible symbol / slot with no configured uplink frequency domain transmission (uplink subband).

[0104] B-1) Determine the frequency domain resource allocation based on the size of the second frequency domain resource, where the second frequency domain resource is the initial uplink BWP, for example, the bits of the frequency domain resource allocation indication are... N2 is the size of the second frequency domain resource.

[0105] B-2) Determine the frequency offset value of PUSCH frequency hopping based on the size of the second frequency domain resource. For example, the frequency offset value of the second hop is... wait.

[0106] Furthermore, if the terminal device 10 transmits PRACH on uplink symbols, it detects the DCI format of CRC scrambled by Type I RNTI; if the terminal transmits PRACH on downlink symbols, it detects the DCI format of CRC scrambled by conventional RA-RNTI.

[0107] It should be noted that the above information transmission method is applicable to at least the following scenarios:

[0108] <1> On the same time slot / symbol, SBFD UEs and non-SBFD UEs are configured with different ROs. The RA-RNTI and the first type RNTI can be used to distinguish which RO the PRACH was sent on, and then SBFD UE-specific Msg 2PDSCH transmission and Msg3 PUSCH scheduling can be performed.

[0109] <2> On the same time slot / symbol, SBFD UEs and non-SBFD UEs are configured with the same RO, but the preamble is different. Different UE types can be distinguished by using RA-RNTI and the first RNTI, and then SBFD UE-specific Msg 2PDSCH transmission can be performed.

[0110] II. Two-step random access:

[0111] (1) New Msg2:

[0112] When terminal device 10 is an SBFD UE, or a UE with resources (uplink subband) for uplink frequency domain transmission in downlink / flexible time slot / symbol configuration, it receives RAR and detects the DCI format scrambled by CRC with type 1 RNTI.

[0113] In one embodiment of this disclosure, the first type of RNTI is:

[0114] The first type of RNTI = 1 + s_id + 14 × t_id + 14 × 80 × f_id + 14 × 80 × 8 × 5

[0115] Where s_id is the index of the first OFDM symbol of the PRACH occasion within a slot (0≤s_id<14); t_id is the index of the first slot of the PRACH occasion within a system frame (0≤t_id<80); and f_id is the index of the PRACH occasion in the frequency domain (0≤f_id<8).

[0116] (2) If the RAR message received by terminal device 10 is a fallback RAR, where fallback RAR means that terminal device 10 failed to access the system successfully during the random access process for some reason, and fallback RAR can also mean an alternative scheme that allows terminal device 10 to retry the random access process, then terminal device 10 transmits the PUSCH according to the RAR grant. The specific method is the same as that used in the two-step random access process to determine the frequency domain resource allocation of the PUSCH according to the scheduling timing of the PUSCH indicated in the RAR UL grant.

[0117] If the RAR message received by the terminal is a Success RAR, which signifies successful access, the terminal device 10 will transmit PUCCH. If the PUCCH transmission time slot indicated by the Success RAR is of type 1, the PUCCH resource is determined according to the first PUCCH resource set; if the PUCCH transmission time slot indicated by the Success RAR is of type 2, the PUCCH resource is determined according to the second PUCCH resource set.

[0118] Figure 6 This is a schematic diagram of an information transmission apparatus according to an embodiment of the present disclosure. Figure 6 As shown, the information transmission device 600 may include at least the following modules.

[0119] The sending module 601 is used to send a random access response message to the terminal device. The cyclic redundancy check (CRC) of the physical downlink control channel (PDCCH) that schedules the random access response message is scrambled by a first-type radio network temporary identifier (RNTI) or a second-type RNTI. The types of terminal devices include: first-type terminal devices and / or second-type terminal devices. The first-type terminal devices correspond to the first-type RNTI and / or the second-type RNTI, and the second-type terminal devices correspond to the second-type RNTI.

[0120] The first type of RNTI is determined based on specific rules, and it differs from the second type of RNTI.

The second type of frequency-domain resource includes the initial uplink BWP dedicated to the second type of terminal device.

[0126] The first type of terminal equipment can support the configuration information of uplink frequency domain resources for subband non-overlapping full-duplex SBFD mode or uplink symbols or flexible symbols or time slots. The second type of terminal equipment cannot support the SBFD mode or uplink frequency domain resources for uplink symbols or flexible symbols or time slots.

[0129] The first type of RNTI is determined based on specific rules, and it differs from the second type of RNTI.
