Communication method and apparatus

[0001] The present application claims priority to the Chinese patent application No. 202411068435.X, filed on August 5, 2024, and entitled "Communication method and apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a communication method and apparatus. BACKGROUND

[0003] In a communication system, a transmitting device can encapsulate data in a transport block, and transmit the data block on multiple physical downlink shared channels (PDSCHs) or physical uplink shared channels (PUSCHs) to improve the reliability of communication. The multiple PDSCH or PUSCH transmissions can be located in different slots, or the multiple PUSCH transmissions can be located in the same slot. Correspondingly, a receiving device can receive the transport block from the transmitting device, and obtain the data in the transport block according to the size (TBS) of the transport block. For example, the transmitting device and the receiving device can determine the size of the transport block by determining the number of resource elements (REs) used for transmitting the PDSCH or PUSCH in a slot.

[0004] However, in a sub-band full-duplex (SBFD) scenario, the multiple PDSCH or PUSCH transmissions can be performed across SBFD type slots / symbols and non-SBFD type slots / symbols, and the available frequency domain resources for PDSCH or PUSCH transmission on the SBFD type slots / symbols and the non-SBFD type slots / symbols can be different. At present, there is no solution related to how to determine the size of the transport block carried by the multiple PDSCH or PUSCH transmissions in this scenario. SUMMARY

[0005] Embodiments of the present application provide a communication method and apparatus, which can determine the size of the transport block carried by the multiple PDSCH or PUSCH transmissions in an SBFD scenario.

[0006] In a first aspect, a communication method is provided, which can be performed by a terminal device. In the absence of special description, the "terminal device" in the present application can refer to the terminal device itself, a component (for example, a processor, a chip, or a chip system, etc.) in the terminal device, or a logic module or software capable of realizing all or part of the terminal device functions. The method comprises: receiving, by the terminal device, first signaling and receiving a first physical downlink shared channel; or transmitting a first physical uplink shared channel. The first signaling is used to schedule the first physical shared channel transmission, the first physical shared channel is used to carry a first transport block, the number of maximum transmission occasions of the first physical shared channel is greater than or equal to 2, part of the transmission occasions of the first physical shared channel is located in a first type time unit, and another part of the transmission occasions of the first physical shared channel is located in a second type time unit. The size of the first transport block is determined according to one or more of the following: the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, or the number of resource blocks associated with the first physical shared channel transmission on the second type time unit. The first type time unit is a sub-band full duplex type time unit. The second type time unit is a non-sub-band full duplex type time unit. The first physical shared channel is a first physical uplink shared channel, or the first physical shared channel is a first physical downlink shared channel.

[0007] Based on the present scheme, unlike determining the size of the first transport block according to the number of resource blocks associated with the first physical shared channel transmission on one time slot, in the present application, the size of the first transport block can be determined according to one or more of the following: the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, or the number of resource blocks associated with the first physical shared channel transmission on the second type time unit. The size of the first transport block carried by multiple first physical shared channel transmissions can be determined in the SBFD scenario.

[0008] In a possible implementation, in the case that the multiple first physical shared channel transmissions correspond to multiple repeated transmissions of the first transport block or the multiple first physical shared channel transmissions correspond to the first transport block being mapped to multiple time slots, the size of the first transport block is determined according to the first transmission number, the second transmission number, the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit. The first transmission number is the number of transmissions of the first physical shared channel on the first type time unit. The second transmission number is the number of transmissions of the first physical shared channel on the second type time unit.

[0009] Based on the possible implementation, the size of the first transport block can be determined according to the number of resource blocks associated with the first physical shared channel transmission on different types of time units and the number of transmission occasions (i.e., the first number of transmissions and the second number of transmissions) of the first physical shared channel transmission on different types of time units, which can comprehensively consider the first physical shared channel on different types of time units, so that the determined size of the first transport block can be more suitable for the channel quality of the first physical shared channel corresponding to different transmission occasions, thereby improving the transmission efficiency.

[0010] In a possible implementation, the first number of transmissions is determined according to the number of maximum transmission occasions of the first physical shared channel and the first type of time unit; and the second number of transmissions is determined according to the number of maximum transmission occasions of the first physical shared channel and the second type of time unit.

[0012] In a possible implementation, the first number of transmissions and the second number of transmissions are further determined according to one or more of the following: the third configuration information, the fourth configuration information, and the fifth configuration information; the third configuration information is used to configure a time division duplex (TDD) uplink-downlink configuration common to a cell; the fourth configuration information is used to configure a TDD uplink-downlink configuration dedicated to a terminal device; and the fifth configuration information is used to configure the time domain position of a synchronization signal / physical broadcast channel block (SSB) transmitted within a half frame of an SSB.

[0013] Based on the above three possible implementations, two feasible schemes are provided for determining the first number of transmissions and the second number of transmissions; the first scheme is to determine the first number of transmissions and the second number of transmissions according to physical slot counting, that is, without considering whether the slots / symbols can be used for the first physical shared channel transmission; and the second scheme is to determine the first number of transmissions and the second number of transmissions according to available slot counting, that is, to determine whether the slots / symbols can be used for the first physical shared channel transmission according to one or more of the above information.

[0133] Before describing the embodiments of the present application, the technical terms related to the embodiments of the present application are described.

[0134] Subband full duplex (SBFD): The communication frequency band of the fifth generation (5G) new radio (NR) wireless communication system is a medium-high frequency band, and high data rate and low delay can be achieved by using a large bandwidth. In a time division duplexing (TDD) system, the downlink (DL) usually occupies the main time domain resources, resulting in coverage imbalance between the DL and the uplink (UL), as shown in FIG. 1, where the horizontal axis represents the time domain and the vertical axis represents the frequency domain. The DL can occupy four time slots, while the UL only occupies one time slot. Compared with a frequency division duplexing (FDD) system, the uplink coverage of the TDD system is poor and the delay is large. Therefore, the R18 standard proposes a subband full duplex (SBFD) scheme to solve the problems of uplink coverage and delay in the TDD system.

[0135] In the SBFD scenario, one carrier can be divided into multiple subbands, and the transmission directions of different subbands can be different. There are two typical SBFD scenarios, which can be shown in FIG. 2. The horizontal axis represents the time domain, and the vertical axis represents the frequency domain. The DL time slot represents that the time slot is used for transmitting DL. The UL time slot represents that the time slot is used for transmitting UL. The SBFD time slot represents that the time slot is used for transmitting UL and DL.

[0136] The first scenario can be shown in (a) of FIG. 2. One carrier is divided into three subbands. The middle subband is used for transmitting UL. The upper and lower subbands are used for transmitting DL.

[0137] The second scenario can be shown in (b) of FIG. 2. One carrier is divided into two subbands. One subband is used for transmitting UL. The other subband is used for transmitting DL.

[0138] When the carrier on one symbol is used for transmitting UL and DL, the symbol can be referred to as an SBFD symbol. When the carrier on one symbol is used for transmitting only UL or DL, the symbol can be referred to as a non-SBFD symbol.

[0139] When the symbols in one time slot are all SBFD symbols, the time slot can be referred to as an SBFD time slot. When the symbols in one time slot are all non-SBFD symbols, the time slot can be referred to as a non-SBFD time slot. In addition, part of the symbols in one time slot can be SBFD symbols, and the other part of the symbols can be non-SBFD symbols, which is not limited in the present application.

[0140] In the R18 standard discussion, it is decided to adopt the technical scheme of “network equipment adopts subband full duplex, and terminal equipment adopts half duplex”. That is, the network equipment can simultaneously transmit UL and DL on the frequency domain resource corresponding to the SBFD symbol (that is, transmit UL on part of the subbands, and transmit DL on part of the subbands). The terminal equipment transmits UL or DL on the frequency domain resource corresponding to the SBFD symbol (that is, cannot simultaneously transmit UL and DL). In the SBFD scheme, the available uplink transmission resource of the terminal equipment is increased, which can effectively improve the uplink coverage and reduce the uplink delay.

[0141] NR multiple transmission: In NR, PDSCH / PUSCH can be transmitted multiple times. There are two types of multiple transmissions: repeated transmission and transport block of multiple slot (TBoMS).

[0142] The repeated transmission is to carry the same data in multiple PDSCH / PUSCH transmissions, that is, the data can be encapsulated in a TB, and the TB is mapped on the PDSCH / PUSCH for repeated transmission. Therefore, the repeated transmission can also be understood as one TB being repeatedly transmitted through multiple PDSCH / PUSCH. Since channel coding processing is performed before the TB is mapped on the PDSCH / PUSCH, the TB carried by each PDSCH / PUSCH transmission can include coded bits of different redundancy versions.

[0143] The repeated transmission is divided according to the scheduling type, which can include downlink control information (DCI) dynamically scheduled repeated transmission and high-layer signaling configured repeated transmission (the high-layer signaling configured repeated transmission can include semi persistent scheduling (SPS) PDSCH, configured grant type 1 (CG type 1) PUSCH, and configured grant type 2 (CG type 2) PUSCH).

[0144] For PDSCH repeated transmission, different PDSCH repeated transmissions of one TB are transmitted in different slots; for PUSCH repeated transmission, different PUSCH repeated transmissions of one TB can be transmitted in different slots (i.e., PUSCH repetition Type A) or in the same slot (i.e., PUSCH repetition Type B). Exemplarily, taking PUSCH repeated transmission as an example, the PUSCH repeated transmission can be transmitted on a flexible symbol (the flexible symbol is a symbol without a link direction, which can be used for transmitting UL or can be used for transmitting DL) or an uplink symbol, as shown in the following FIG. 3, the TB can be mapped on multiple PUSCH transmissions (such as mapping the TB to the first PUSCH transmission, mapping the TB to the second PUSCH transmission,..., and mapping the TB to the Nth PUSCH transmission) to realize the PUSCH repeated transmission. Wherein, N is an integer greater than 1.

[0145] In NR, the time-frequency resource allocation and modulation and coding scheme (MCS) of each PDSCH / PUSCH repeated transmission are the same, so the size of the TB on different PDSCH / PUSCH transmissions is also the same. The size of the TB is determined by the time-frequency resource allocation and the MCS, and the process of determining the size of the TB by the terminal device can be as shown in the following FIG. 4:

[0146] S401, the terminal device determines the number of REs for PDSCH / PUSCH transmission in a slot.

[0147] wherein the number of REs for PDSCH / PUSCH transmission in a slot satisfies the following formula: N RE = min(156, N' RE )*n RB .

[0148] wherein n RB is the number of resource blocks (RBs) allocated for the PDSCH / PUSCH transmission.

[0149] wherein one RB includes 12 subcarriers, and the RB can be a physical resource block (PRB) or a virtual resource block (VRB), without limitation.

[0150] wherein N' RE represents the number of REs allocated for PDSCH / PUSCH transmission in one RB, and N' RE satisfies the following formula:

[0151] wherein, is the number of subcarriers included in one RB (e.g., 12), is the number of symbols occupied by PDSCH / PUSCH transmission in a slot, is the number of REs of demodulation reference signal (DMRS) in the duration of PDSCH / PUSCH scheduling, is the overhead configured by a higher layer parameter or predefined.

[0152] S402, the terminal device determines a non-quantized intermediate variable according to the number of REs for PDSCH / PUSCH transmission in a slot.

[0153] wherein the intermediate variable satisfies the following formula: N info = N RE · R · Q m · v.

[0154] wherein R represents code rate, and Q mwherein, v represents the number of layers of multi-input multi-output (MIMO), and v can also be understood as the number of allocated DMRS ports.

[0155] S403, the terminal device quantizes the intermediate variable to obtain a quantized value, and determines the size (i.e., TBS) of the TB according to the quantized value.

[0156] Optionally, if the intermediate variable N info ≤ 3824, the quantized value is wherein, and the value closest to N' info may be found as the TBS according to Table 1 below. For example, taking N' info = 550 as an example, the TBS can be the value corresponding to the index 41 in Table 1, i.e., the TBS can be 552. info

[0157] Table 1

[0158] Optionally, if the intermediate variable N info > 3824, the quantized value is wherein, round is a rounding up operation. Further, when R ≤ 1 / 4, wherein, or, when the intermediate variable N info > 8424, the quantized value is wherein, or, when R > 1 / 4,

[0159] wherein, TBoMS is the mapping of one TB to PUSCH transmission in multiple slots, and TBoMS can be as shown in FIG. 5, part of the information of one TB can be mapped to one PUSCH transmission in one slot, i.e., the whole information of one TB can be jointly carried by PUSCH transmission in N slots.

[0160] It can be understood that the time-frequency resource allocation of each PUSCH transmission is the same, i.e., the size of the part of the TB carried by one PUSCH transmission in each slot is the same, and then the size of the TB can be determined by the total time-frequency resources corresponding to N times of PUSCH transmission.

[0161] ​Specifically, the terminal device can determine the unquantized intermediate variable based on the number of REs used for PDSCH / PUSCH transmission within multiple time slots corresponding to a TB, and then quantize the intermediate variable to obtain a quantized value. The size of the TB is then determined based on the quantized value. The number of REs used for PDSCH / PUSCH transmission within multiple time slots can satisfy the following formula: N RE =N*min(156,N′) RE )*n RB .

[0162] Where N is the number of time slots corresponding to one TB, min(156,N′) RE )*n RB The determination can be referenced in S401 for min(156, N′) RE )*n RB The determination of [the specific details] will not be elaborated upon here.

[0163] Based on the above description of SBFD scenarios and multiple PDSCH / PUSCH transmissions, the R19 standard discusses that multiple transmissions such as PDSCH repetition, PUSCH repetition, and PUSCH TBoMS can span SBFD and non-SBFD symbols. Taking PUSCH repetition transmission spanning SBFD and non-SBFD symbols (such as UL symbols) as an example, at least one PUSCH transmission can be performed on an SBFD time slot (an SBFD time slot includes multiple SBFD symbols) / SBFD symbol, and at least one PUSCH transmission can be performed on a non-SBFD time slot (a non-SBFD time slot includes multiple non-SBFD symbols) / non-SBFD symbol, as shown in Figure 6. The TB is carried by four PUSCH transmissions, of which the first to third PUSCH transmissions are located in the SBFD time slot, and the fourth PUSCH transmission is located in the UL time slot (i.e., a non-SBFD time slot).

[0164] For PUSCH, because the available uplink frequency domain resources on SBFD symbols are only the uplink subband within a single carrier, while on non-SBFD symbols the available uplink frequency domain resources are the entire carrier, the allocated frequency domain resources (or number of RBs) for PUSCH transmissions performed on SBFD and non-SBFD symbols will differ. Similarly, for PDSCH, the allocated frequency domain resources (or number of RBs) for PDSCH transmissions performed on SBFD and non-SBFD symbols may also differ.

[0165] Therefore, in the SBFD scenario, there is currently no solution for determining the size of the transport block carried by multiple PDSCH / PUSCH transmissions.

[0166] The application provides a communication method, which comprises: a terminal device receiving first signaling and receiving a first physical downlink shared channel; or, the terminal device sending a first physical uplink shared channel. The first signaling is used for scheduling first physical shared channel transmission, the first physical shared channel is used for carrying a first transport block, the number of maximum transmission occasions of the first physical shared channel is greater than or equal to 2, part of the transmission occasions of the first physical shared channel is located in a first type time unit, and another part of the transmission occasions of the first physical shared channel is located in a second type time unit. The size of the first transport block is determined according to one or more of the following: the number of resource blocks associated with the first physical shared channel transmission on the first type time unit or the number of resource blocks associated with the first physical shared channel transmission on the second type time unit. The first type time unit is a sub-band full-duplex type time unit. The second type time unit is a non-sub-band full-duplex type time unit. The first physical shared channel is a first physical uplink shared channel, or the first physical shared channel is a first physical downlink shared channel.

[0167] In the embodiments of the application, unlike determining the size of the first transport block according to the number of resource blocks associated with the first physical shared channel transmission on one time slot, in the application, the size of the first transport block can be determined according to one or more of the following: the number of resource blocks associated with the first physical shared channel transmission on the first type time unit or the number of resource blocks associated with the first physical shared channel transmission on the second type time unit, and the size of the first transport block carried by multiple first physical shared channel transmissions can be determined in an SBFD scenario.

The network device can be a node in a radio access network (RAN), or can be a base station, which can be referred to as a radio access network node (or device).

[0177] For example, the network device can include an evolved Node B (NodeB or eNB or e-NodeB, evolutional Node B) in an LTE system or an LTE-advanced (LTE-A) system, such as a conventional macro base station eNB and a micro base station eNB in a heterogeneous network scenario. Alternatively, the network device can include a next generation Node B (gNB) in an NR system. Alternatively, the network device can include a transmission reception point (TRP), a home base station (for example, a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), a BBU pool, or a Wi-Fi access point (AP), and the like.

Alternatively, the network device can be a device that implements a base station function in an IoT, such as a device that implements a base station function in unmanned aerial vehicle communication, V2X, D2D, or machine to machine (M2M).

[0178] Optionally, the base station in the embodiments of the present application can include various forms of base stations, such as a macro base station, a micro base station (also referred to as a small station), a relay station, an access point, a home base station, a TRP, a transmitting point (TP), or a mobile switching center, and the like, which are not specifically limited in the embodiments of the present application.

[0179] Alternatively, the communication between each network device and each terminal device in the communication system shown in FIG. 8 can also be represented in another form, as shown in FIG. 9, the terminal device 91 can include a processor 911, a memory 912, and a transceiver 913, the transceiver 913 can include a transmitter 9131, a receiver 9132, and an antenna 9133; the network device 92 can include a processor 921, a memory 922, and a transceiver 923, the transceiver 923 can include a transmitter 9231, a receiver 9232, and an antenna 9233.

[0180] For example, the receiver 9132 of the terminal device 91 can receive the transmission control information through the antenna 9133, and the transmitter 9131 of the terminal device 91 can send the transmission feedback information to the network device 92 through the antenna 9133; the transmitter 9231 of the network device 92 can be used to send the transmission control information to the terminal device 91 through the antenna 9233, and the receiver 9232 of the network device 92 can be used to receive the transmission feedback information sent by the terminal device 91 through the antenna 9233.

[0181] Among them, the core network device can include a network element implementing control plane function and a network element implementing user plane function.

[0182] Among them, the network element in the core network for implementing the control plane function can be an access and mobility function network element, for example, an access and mobility management (AMF) network element in a 5G system, the AMF network element is used to be responsible for the mobility management in the mobile network, such as the location update of the terminal device, the registration network of the terminal device, the handover of the terminal device, etc.

[0183] Among them, the network element in the core network for implementing the user plane function can be a user plane function network element, for example, a user plane function (UPF) network element in a 5G system, the UPF network element is used to be responsible for the forwarding and receiving of data in the terminal device.

[0184] Based on the above description of the communication system, the present application can be applied to the RAN architecture, and the following FIG. 10 is an example diagram of the RAN architecture.

[0185] Among them, the network device can communicate with the core network device through the backhaul link, and can communicate with the terminal device through the air interface.

[0186] In one example, a network device can include a baseband unit (BBU) and a remote radio unit (RRU). The BBU and RRU can be placed in different locations, for example, RRU pull-out, placed in a high traffic area, and the BBU placed in a central machine room. The BBU and RRU can also be placed in the same machine room. The BBU and RRU can also be different components under one rack.

[0187] In another example, a network device can also be a device including a centralized unit (CU) node, or including a distributed unit (DU) node, or including a CU node and a DU node. For example, the network device can be divided into a CU and a DU from a logical function perspective, and the functions of part of the protocol layers are placed in the CU for centralized control, and the rest or all of the protocol layers are distributed in the DU and controlled by the CU. The CU and the DU can be separately arranged, or can be included in the same network element, such as the BBU. Further, the CU can also be divided into a control plane (C-Plane), which can also be referred to as a CU-CP, and a user plane (U-Plane), which can also be referred to as a CU-UP.

[0188] In this case, the CU and the DU can communicate through a midhaul link.

[0189] In another example, a network device can also be a device including a CU, a DU, and a radio unit (RU), or including a CU, a DU, and a RU. In this case, the RU can be included in a radio frequency device or a radio frequency unit, such as an RRU, an active antenna unit (AAU), or a remote radio head (RRH).

[0190] In this case, the RU can communicate with at least one terminal device through an air interface.

[0191] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, the network device can be a network device or a module of the network device in an opening RAN (O-RAN) system. In the O-RAN system, the CU can also be referred to as an opening (O)-CU, the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0192] In one possible implementation, the network element function division and protocol layer structure diagram of the device in the RAN system can be as shown in FIG. 11.

[0193] Among them, the CU is a logical node that carries the radio resource control (RRC) layer, the service data adaptation protocol (SDAP) layer, the packet data convergence protocol (PDCP) layer and other control functions of the network device. The CU can be connected to network nodes such as core network devices through some interfaces, and the interfaces can be E2 interfaces and the like.

[0194] Optionally, the CU can have part of the functions of the network device, for example, the CU (such as the PDCP layer and higher layers) can be connected to the DU (such as the radio link control (RLC) layer and lower layers) through some interfaces, and the interfaces can be F1 interfaces.

[0195] In some examples, the interfaces (such as the F1 interface) can provide control plane and user plane functions (such as interface management, system information management, UE context management, RRC message transmission, etc.). The F1 application protocol (AP) is the application protocol of the F1 interface, and the F1 interface can be split into F1 control plane (F1-C) and F1 user plane (F1-U).

[0196] In some examples, the CU-CP is a logical node carrying the RRC layer and the PDCP control plane part (PDCP-C) layer, used to implement the control plane function of the CU; the CU-CP can interact with the network element in the core network for implementing the control plane function. The CU-UP is a logical node carrying the SDAP layer and the PDCP user plane part (PDCP-U) layer, used to implement the user plane function of the CU. The CU-UP can interact with the network element in the core network for implementing the user plane function.

[0197] In some examples, the DU can control at least one RU, and the DU is connected with the RU through some interfaces, which can be a front-haul interface. In some examples, the PHY-H layer includes part of the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like.

[0198] The above configuration of the CU and the DU is only an example, and the functions of the CU and the DU can be configured as needed. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have part of the processing functions of the protocol layer. For example, part of the functions of the RLC layer and the functions of the protocol layer above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to the service type or other system requirements, for example, according to the delay, the functions that need to meet the requirement of shorter delay are arranged in the DU, and the functions that do not need to meet the requirement of shorter delay are arranged in the CU.

[0199] In some examples, the RU is a logical node carrying the lower physical layer (PHY-L) and the radio frequency link.

[0200] In some examples, the PHY-L includes part of the PHY processing, such as fast fourier transform (FFT), inverse fast fourier transformation (IFFT), digital beamforming, filtering, and the like.

[0201] It can be understood that the DU and the RU can be co-located or not co-located. The DU and the RU exchange control plane information and user plane information via a lower-layer split-cus-plane (LLS-CUS) interface through a front-haul link. The LLS-CUS can include an LLS-C interface and an LLS-U interface that provide a control plane (C-Plane) and a user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via an LLS-M interface of the front-haul link, and the management plane (M-Plane) refers to non-real-time management operations between the DU and the RU.

[0202] The DU and the RU can cooperate to jointly implement the functions of the PHY layer. The functions possessed by the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functions, and the RU is configured to implement intermediate radio frequency functions. For another example, the DU is configured to implement high-layer functions in the PHY layer, and the RU is configured to implement low-layer functions in the PHY layer or implement the low-layer functions and radio frequency functions.

[0203] It can be understood that the high-layer functions in the PHY layer can include a part of the functions of the PHY layer that are closer to the MAC layer, and the low-layer functions in the PHY layer can include another part of the functions of the PHY layer that are closer to the intermediate radio frequency side.

[0204] Based on the above description of the RAN, the RAN chip architecture can be as shown in FIG. 12, which can include a CU, a DU, and a RU, where the CU is a platform for implementing layer 2 (L2) functions and layer 3 (L3) functions, the RU is used to implement layer 1 (L1) computing functions and RF digital part functions, and the DU is used to implement L1 functions and part of L2 functions. The middle and backhaul interfaces are used to carry traffic between the CU and the DU and between the CU and the core network. The front and backhaul interfaces are used to carry traffic between the RU and the DU and between the CU and the DU. The integrated DU can include the above-mentioned DU functions and RU functions.

[0205] The CU / DU hardware includes a chassis platform, a mainboard, peripheral devices, and cooling devices. The mainboard contains a processing unit, a memory, an internal I / O interface, and an external connection port. The hardware accelerator design has an interface, and the hardware function components include storage of software, hardware, and system debugging interfaces, and a single-board management controller.

[0206] Among them, the DU system is usually implemented using multi-core processors and one or more hardware accelerators. Part of the DU protocol stack can be implemented in software running on a multi-core processor, and the computationally intensive L1 and L2 functions can be carried on hardware accelerators based on field-programmable gate arrays (FPGA) / graphics processing units (GPU); or all L1 functions are carried on hardware accelerators based on FPGA / GPU, while other protocol stack contents are implemented in software running on a processor; or all protocol stacks are implemented in software running on a processor. The hardware accelerator supports interconnection with an x86 or non-x86 processor, and the accelerator has a multi-channel extended peripheral component interconnect (PCIe) interface pointing to a central processing unit (CPU) and is externally connected through a GbE connection.

[0207] Among them, the RU can include three parts: an O-RAN processing unit (OPU), a data processing unit (DPU), and an RF processing unit of the O-RU.

[0208] Among them, the OPU receives extended common public radio interface (eCPRI) frames from the O-RAN fronthaul and performs the fronthaul interface, the bottommost L1 (encoding, scrambling, modulation, layer mapping, precoding), synchronization, digital beamforming (BF), and resource unit mapping. The OPU can be implemented as a CPU, FPGA, or application-specific integrated circuit (ASIC).

[0209] The DPU performs synchronization, digital downlink conversion (DDC) in the UL, digital uplink conversion (DUC) in the DL, crest factor reduction (CFR), and digital pre-distortion (DPD) to improve power amplifier efficiency by reducing the peak average power ratio (PAPR) / adjacent channel leakage ratio (ACLR) of the RF front end. In addition, the DPU can be implemented as an FPGA or an ASIC.

[0210] The RF processing unit of the O-RU includes a transceiver module, an up / down converter, a power amplifier (PA), a low noise amplifier (LNA), and a transmit / receive (Tx / Rx) filter. All conversions between the analog domain and the digital domain (e.g., DAC and ADC) are performed within the transceiver module (e.g., RF sampling, frequency conversion using RF, intermediate frequency (IF), and local oscillator (LO) mixing in upconversion and downconversion). Note that the physical and logical partitions within the RF processing unit do not require specific boundaries.

[0211] It should be noted that the communication system described in the embodiments of the present application is for more clearly illustrating the technical solutions of the embodiments of the present application, and does not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0212] In a specific implementation, each of the terminal device, the network device, and the core network device shown in FIG. 8 can have the component structure shown in FIG. 13, or include the components shown in FIG. 13. FIG. 13 is a component structure diagram of a communication apparatus 130 according to an embodiment of the present application. The communication apparatus 130 can be a chip or a system on chip in the terminal device, the network device, and the core network device. Alternatively, the communication apparatus 130 can be a chip or a system on chip in the terminal device, the network device, and the core network device.

[0213] As shown in FIG. 13, the communication device 130 includes one or more processors 1301. Further, the communication device 130 can also include a communication bus 1302, and at least one communication interface (only exemplary in FIG. 13, for example, the communication device 130 includes a communication interface 1304, and one processor 1301 is taken as an example for description). Optionally, the communication device 130 can also include a memory 1303.

[0214] The processor 1301 can be a general-purpose CPU, a microprocessor, an ASIC, or one or more integrated circuits for controlling program execution of the solutions of the present application, or a processing core for processing data (for example, computer program instructions). The processor can be a single-CPU processor or a multi-CPU processor.

[0215] In a specific implementation, as an example, the processor 1301 can include one or more CPUs, for example, CPU0 and CPU1 in FIG. 13.

[0216] The communication bus 1302 can be a peripheral component interconnect (PCI) bus or an extended industry standard architecture (EISA) bus, etc. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, only one thick line is shown in FIG. 13, but it does not mean that there is only one bus or only one type of bus. The communication bus 1302 is used to connect different components in the communication device 130, so that different components in the communication device 130 can communicate with each other.

[0217] The communication interface 1304 can be a transceiver module for communicating with other devices or communication networks, which can be, for example, an Ethernet, a radio access network (RAN), or a wireless local area network (WLAN), etc. Exemplarily, the communication interface 1304 can be a transceiver, a transceiver device, or the like. Alternatively, the communication interface 1304 can also be a transceiver circuit located in the processor 1301, to realize the signal input and signal output of the processor.

[0218] The memory 1303 can be a device with a storage function. For example, it can be a read-only memory (ROM) or other type of static storage device that can store static information and instructions, a random access memory (RAM) or other type of dynamic storage device that can store information and instructions, and can also be an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, an optical disc storage (including a compact disc, a laser disc, an optical disc, a digital versatile disc, a Blu-ray disc, etc.), a magnetic disc storage medium or other magnetic storage device, or any other medium capable of carrying or storing desired program code in the form of instructions or data structures and capable of being accessed by a computer, but is not limited thereto. The memory can exist independently and be connected to the processor through the communication bus 1302. The memory can also be integrated with the processor.

[0219] For example, the memory 1303 is configured to store computer-executable instructions for implementing the solutions of the present application, and the processor 1301 is configured to control the execution of the computer-executable instructions. The processor 1301 is configured to execute the computer-executable instructions stored in the memory 1303, so as to implement the methods provided in the embodiments of the present application.

[0220] Alternatively, in the embodiments of the present application, the processor 1301 can also perform the processing-related functions in the methods provided in the embodiments of the present application, and the communication interface 1304 is responsible for communication with other devices or communication networks, which is not limited in the embodiments of the present application.

[0221] Alternatively, in the embodiments of the present application, the computer-executable instructions can also be referred to as application program codes, which are not limited in the embodiments of the present application.

The output device 1305 communicates with the processor 1301 and can display information in various ways. For example, the output device 1305 can be a liquid crystal display (LCD), a light emitting diode (LED) display device, a cathode ray tube (CRT) display device, or a projector, etc. The input device 1306 communicates with the processor 1301 and can receive user input in various ways. For example, the input device 1306 can be a mouse, a keyboard, a touch screen device, a sensor device, etc.

[0223] It should be noted that the constituent structure shown in FIG. 13 does not constitute a limitation on the communication apparatus, and the communication apparatus can include more or fewer components than those shown in FIG. 13, or combine certain components, or different component arrangements.

[0224] The communication method provided by the embodiments of the present application will be described below with reference to the accompanying drawings. It can be understood that, in the embodiments of the present application, the terminal device, the network device, and the core network device can perform some or all of the steps in the embodiments of the present application, and these steps or operations are only examples, and the embodiments of the present application can also perform other operations or variations of various operations. In addition, the various steps can be performed in different orders presented in the embodiments of the present application, and it is possible that not all operations in the embodiments of the present application are performed.

[0225] As shown in FIG. 14, it is an interaction diagram of a communication method provided by the present application. The communication method is illustrated by the interaction between the terminal device and the network device. The steps performed by a single execution subject (for example, the terminal device and the network device) in the embodiments of the present application can also be divided into steps performed by multiple execution subjects, which can be logically and / or physically separated. For example, referring to FIG. 14, the communication method includes the following steps:

[0226] S1401, the network device sends first signaling; correspondingly, the terminal device receives the first signaling.

[0227] The first signaling is used to schedule first physical shared channel transmission.

[0228] It can be understood that the network device or the terminal device can determine the scheduling grant corresponding to the first physical shared channel transmission according to the first signaling, and perform the first physical shared channel transmission based on the first signaling.

[0229] The first physical shared channel is a first physical uplink shared channel, or the first physical shared channel is a first physical downlink shared channel.

[0230] In an example, when the first physical shared channel is any one of: an SPS PDSCH, a configured grant type 1 PUSCH, or a configured grant type 2 PUSCH, the first signaling can be understood as a high-layer configured parameter. Further, when the first physical shared channel is any one of: an SPS PDSCH, or a configured grant type 1 PUSCH, the network device can activate the scheduling grant contained in the first signaling through DCI, and when the first physical shared channel is a configured grant type 2 PUSCH, the first signaling takes effect directly.

[0231] In another example, when the first physical shared channel is any one of: a DCI dynamically scheduled PDSCH, or a DCI dynamically scheduled PUSCH, the network device can send the first signaling through DCI, that is, the first signaling is located in the DCI.

[0232] The number of maximum transmission occasions of the first physical shared channel is greater than or equal to 2, that is, there are multiple first physical shared channel transmissions, and the multiple first physical shared channel transmissions are located in different transmission occasions.

[0233] The first physical shared channel is located in a first type of time unit, and the first physical shared channel is located in a second type of time unit. It can also be understood that at least one of the multiple first physical shared channel transmissions is located in the first type of time unit, and at least one of the multiple first physical shared channel transmissions is located in the second type of time unit.

[0234] The first type of time unit is a sub-band full duplex type of time unit, that is, a part of subcarriers on the first type of time unit are used for uplink transmission, for example, a sub-band duplex uplink sub-band, and another part of subcarriers on the first type of time unit are used for downlink transmission, for example, a sub-band duplex downlink sub-band.

[0235] For example, the first type of time unit can be an SBFD symbol (for example, the first physical shared channel transmission can occupy one or more SBFD symbols), or the first type of time unit can be an SBFD slot (for example, the first physical shared channel transmission can occupy one or more SBFD slots).

[0236] The second type of time unit is a non-sub-band full duplex type of time unit, that is, all carriers on the second type of time unit are used for uplink transmission, or all carriers on the second type of time unit are used for downlink transmission.

[0237] For example, the second type of time unit can be a non-SBFD symbol (e.g., the first physical shared channel transmission can occupy one or more non-SBFD symbols), or the second type of time unit can be a non-SBFD slot (e.g., the first physical shared channel transmission can occupy one or more non-SBFD slots).

[0238] It can be understood that the symbols in a slot can all be SBFD symbols, or can all be non-SBFD symbols; or the symbols in a slot can be partially SBFD symbols and partially non-SBFD symbols, which is not limited in the present application.

[0239] The first physical shared channel is used to carry the first transport block.

[0240] It can be understood that the first physical shared channel transmissions on different transmission occasions are all used to carry the first transport block.

[0241] The size of the first transport block is determined according to one or more of the following: the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit, or the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit.

[0242] The first physical shared channel transmission on the first type of time unit can be understood as that the time domain resource corresponding to the first physical shared channel transmission is the first type of time unit, for example, taking the first type of time unit as an SBFD slot as an example, the first physical shared channel transmission can occupy one or more SBFD slots; or taking the first type of time unit as an SBFD symbol as an example, the first physical shared channel transmission can occupy one or more SBFD symbols. In addition, the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit can be understood as the number of resource blocks on the frequency domain resource occupied by the first physical shared channel transmission on the first type of time unit.

[0243] For example, as shown in (a) of FIG. 15, taking the first type of time unit as an SBFD symbol, and taking the first physical shared channel as a first physical downlink shared channel as an example, in the time domain, the first physical downlink shared channel transmission can occupy 7 SBFD symbols, and in the frequency domain, the first physical downlink shared channel transmission can occupy 3 resource blocks, that is, the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit can be 3.

[0244] The first physical shared channel transmission on the second type time unit can be understood as the time domain resource corresponding to the first physical shared channel transmission being the second type time unit. For example, taking a non-SBFD slot as the second type time unit, the first physical shared channel transmission can occupy one or more non-SBFD slots; or taking a non-SBFD symbol as the second type time unit, the first physical shared channel transmission can occupy one or more non-SBFD symbols. In addition, the number of resource blocks associated with the first physical shared channel transmission on the second type time unit can be understood as the number of resource blocks on the frequency domain resource occupied by the first physical shared channel transmission on the second type time unit.

[0245] For example, as shown in (b) of FIG. 15, taking a non-SBFD symbol as the first type time unit, and taking a first physical downlink shared channel as the first physical shared channel, in the time domain, the first physical downlink shared channel transmission can occupy 7 non-SBFD symbols, and in the frequency domain, the first physical downlink shared channel transmission can occupy 6 resource blocks, that is, the number of resource blocks associated with the first physical shared channel transmission on the second type time unit can be 6.

[0246] It can be understood that the size of the first transport block can be determined according to the time domain resource and the frequency domain resource occupied by the first physical shared channel, the number of time units occupied by the first physical shared channel on different transmission occasions in the time domain is the same (that is, the first physical shared channel on different transmission occasions occupies the same number of symbols or the same number of slots), and the number of resource blocks used for the first physical shared channel transmission on different types of time units can be different, which can cause the number of resource blocks occupied by the first physical shared channel on different transmission occasions in the frequency domain to be different, thereby causing the size of the first transport block carried by the first physical shared channel on different transmission occasions to be different. Therefore, the size of the first transport block can be determined by determining the number of resource blocks occupied by the first physical shared channel transmission in the frequency domain, and the number of resource blocks occupied by the first physical shared channel in the frequency domain can be determined according to one or more of the following: the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, or the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0247] The specific determination of the size of the first transport block can refer to the description of determining the size of the first transport block in the following three possible designs, which will not be described here.

[0248] In S1402, the network device sends the first physical downlink shared channel to the terminal device; correspondingly, the terminal device receives the first physical downlink shared channel from the network device.

[0249] Alternatively, the terminal device sends the first physical uplink shared channel to the network device; correspondingly, the network device receives the first physical uplink shared channel from the terminal device.

[0250] For the first physical downlink shared channel, the network device can determine the first physical downlink shared channel corresponding to the first transport block according to the first signaling, and send the first transport block on the first physical downlink shared channel; correspondingly, the terminal device can determine the first physical downlink shared channel corresponding to the first transport block according to the first signaling, and receive the first transport block from the network device on the first physical downlink shared channel.

[0251] Wherein, when the network device sends the first transport block to the terminal device, it can determine the size of the first transport block, map the first transport block to the first physical downlink shared channel according to the size of the first transport block, that is, the first transport block can be carried on the first physical downlink shared channel for transmission; correspondingly, the terminal device can receive the first transport block from the network device based on the first physical downlink shared channel, determine the data in the first transport block by determining the size of the first transport block, and realize communication with the network device.

[0252] For the first physical uplink shared channel, the terminal device can determine the first physical uplink shared channel corresponding to the first transport block according to the first signaling, and send the first transport block on the first physical uplink shared channel; correspondingly, the network device can receive the first transport block from the terminal device on the first physical uplink shared channel.

[0253] Wherein, when the terminal device transmits the first transport block to the network device, it can determine the size of the first transport block, map the first transport block to the first physical uplink shared channel according to the size of the first transport block, that is, the first transport block can be carried on the first physical uplink shared channel for transmission; correspondingly, the network device can receive the first transport block from the terminal device based on the first physical uplink shared channel, determine the data in the first transport block by determining the size of the first transport block, and realize communication with the terminal device.

[0254] Based on the communication method shown in FIG. 14, unlike determining the size of the first transport block according to the number of resource blocks associated with the first physical shared channel transmission on one time slot, in this application, the size of the first transport block can be determined according to one or more of the following: the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit, or the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit. The size of the first transport block carried by the first physical shared channel transmission can be determined multiple times in the SBFD scenario.

[0255] Based on the communication method shown in FIG. 14, optionally, the case that part of the transmission occasions of the first physical shared channel is located in the first type time unit and another part of the transmission occasions of the first physical shared channel is located in the second type time unit can be the following three cases:

[0256] The first possible case is that the multiple transmissions of the first physical shared channel correspond to the multiple repeated transmissions of the first transport block, that is, the first transport block is repeatedly transmitted through multiple first physical shared channels, and different transmissions of the first physical shared channel can be located in different transmission occasions. For details, refer to the content shown in FIG. 3 described above.

[0257] Among them, at least one of the multiple transmissions of the first physical shared channel can be located in the first type time unit, and at least one of the multiple transmissions of the first physical shared channel can be located in the second type time unit.

[0258] The second possible case is that the multiple transmissions of the first physical shared channel correspond to the mapping of the first transport block to multiple slots, that is, the first transport block is transmitted through the first physical shared channel on multiple slots, each transmission of the first physical shared channel carries part of the information of the first transport block, and the transmissions of the first physical shared channel on different slots can be located in different transmission occasions. For details, refer to the content shown in FIG. 5 described above.

[0259] Among them, the transmission of the first physical shared channel on at least one of the multiple slots can be located in the first type time unit, and the transmission of the first physical shared channel on at least one of the multiple slots can be located in the second type time unit.

[0260] The third possible case is that the multiple transmissions of the first physical shared channel correspond to the mapping of the first transport block to multiple slots and Y times of repeated transmission, that is, the first transport block is transmitted through the first physical shared channel on multiple slots, each transmission of the first physical shared channel carries part of the information of the first transport block, and at the same time, the first transport block is repeatedly transmitted through multiple first physical shared channels. As shown in the following FIG. 16, the first transport block can be repeatedly transmitted Y times, and in each repeated transmission, the first transport block can be mapped to the first physical shared channel on multiple slots (such as M) for transmission, that is, the first transport block can be transmitted M*Y times through the first physical shared channel. Different transmissions of the first physical shared channel correspond to different transmission occasions.

[0261] Among them, M is an integer greater than 1.

[0262] Among them, at least one of the multiple transmissions of the first physical shared channel can be located in the first type time unit, and at least one of the multiple transmissions of the first physical shared channel can be located in the second type time unit.

[0263] Based on the communication method shown in FIG. 14, the present application proposes three possible designs for determining the size of the first transport block. The first possible design is to determine the size of the first transport block in the case of multiple transmissions of the first physical shared channel corresponding to multiple repeated transmissions of the first transport block. The second possible design is to determine the size of the first transport block in the case of multiple transmissions of the first physical shared channel corresponding to the mapping of the first transport block to multiple slots. The third possible design is to determine the size of the first transport block in the case of multiple transmissions of the first physical shared channel corresponding to the mapping of the first transport block to multiple slots and Y times repeated transmission. For the convenience of understanding, the present application takes the terminal device determining the size of the first transport block as an example for specific description. It can be understood that the way of the terminal device determining the size of the first transport block in the present application is also applicable to the network device determining the size of the first transport block, and the way of the network device determining the size of the first transport block is not described herein.

[0264] The first possible design is described in detail as follows:

[0265] The terminal device can determine the size of the first transport block according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit. Alternatively, the size of the first transport block can be determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit or the number of resource blocks associated with the first physical shared channel transmission on the second type time unit. The present application proposes two possible implementations:

[0266] In the first possible implementation, the size of the first transport block can be determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0267] Specifically, the size of the first transport block can be determined according to the first transmission times, the second transmission times, the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0268] The first transmission times refer to the number of transmissions of the first physical shared channel on the first type time unit.

[0269] The second transmission times refer to the number of transmissions of the first physical shared channel on the second type time unit.

[0270] For example, assuming that the first first physical shared channel transmission, the third first physical shared channel transmission, the fifth first physical shared channel transmission, and the seventh first physical shared channel transmission are located on the first type time unit, and the second first physical shared channel transmission, the fourth first physical shared channel transmission, the sixth first physical shared channel transmission, the eighth first physical shared channel transmission, the ninth first physical shared channel transmission, and the tenth first physical shared channel transmission are located on the second type time unit, the first transmission number can be 4, and the second transmission number can be 6.

[0271] Based on the above description of the size of the first transport block, the present application proposes a possible embodiment, the size of the first transport block can be determined according to a first product and a second product. The first product is the product of a first coefficient and the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, and the first coefficient is the ratio of the first transmission number to the number of maximum transmission occasions of the first physical shared channel. The second product is the product of a second coefficient and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit, and the second coefficient is the ratio of the second transmission number to the number of maximum transmission occasions of the first physical shared channel.

[0272] The number of resource blocks associated with the first physical shared channel transmission on the first type time unit and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit can be weighted and averaged (i.e., the number of resource blocks associated with the first physical shared channel transmission on the first type time unit is multiplied by the first coefficient, and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit is multiplied by the second coefficient) to obtain a first resource block number, which is the number of resource blocks used to determine the size of the first transport block, i.e., the first resource block number can be the sum of the first product and the second product.

[0273] For example, the first resource block number can satisfy the following formula:

[0274] where n RB is the first resource block number, a SBFD is the first coefficient, a non-SBFD is the second coefficient, is the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, is the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0275] For example, the first coefficient can satisfy the following formula: a SBFD = NSBFD / N total .

[0276] wherein, N SBFD represents the first transmission times, N total represents the number of maximum transmission occasions of the first physical shared channel.

[0277] For another example, the second coefficient can satisfy the following formula: a non-SBFD =N non-SBFD / N total .

[0278] wherein, N non-SBFD represents the second transmission times.

[0279] Based on the above possible embodiments, the number of resource blocks used to determine the size of the first transmission block (i.e., the first number of resource blocks) can be determined by performing a weighted average on the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit and the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit, which can improve the accuracy of determining the size of the first transmission block, thereby improving the reliability of communication. In addition, since the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the two types of time units, the determined size of the first transmission block can be more suitable for the channel quality of multiple first physical shared channel transmissions, which can improve the transmission efficiency.

[0280] In a second possible implementation, the size of the first transmission block can be determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit or the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit. The present application proposes two possible embodiments:

[0281] In a first possible embodiment, the size of the first transmission block is determined according to the first information. The first information is used to indicate that the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit, or the first information is used to indicate that the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit.

[0282] The first information can be predefined or configured by the network device (e.g., the first information can be carried in high-layer signaling such as radio resource control (RRC) signaling, system information, etc., or the first information can be carried in DCI, or the first information can be carried in a media access control (MAC) control element (CE)).

[0283] For example, assuming that the first information occupies one bit, the bit value can be set to 1 to indicate that the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit; or the bit value can be set to 0 to indicate that the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit. Alternatively, the bit value can be set to 0 to indicate that the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit; or the bit value can be set to 1 to indicate that the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit.

[0284] In a second possible embodiment, the size of the first transport block can be determined according to any one of the following preset rules: a first preset rule, a second preset rule, or a third preset rule.

[0285] For the first preset rule, the first preset rule can include one or more of the following: in a case where the ratio of the first transmission number to the number of maximum transmission occasions of the first physical shared channel is greater than 1 / 2 (or the ratio of the second transmission number to the number of maximum transmission occasions of the first physical shared channel is less than 1 / 2), the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit; or in a case where the ratio of the second transmission number to the number of maximum transmission occasions of the first physical shared channel is greater than 1 / 2 (or the ratio of the first transmission number to the number of maximum transmission occasions of the first physical shared channel is less than 1 / 2), the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit.

[0286] In a first example, the terminal device can determine α SBFD In a case where α SBFD >1 / 2, the size of the first transport block can be determined by the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit; or in a case where α SBFD <1 / 2, the size of the first transport block can be determined by the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit.

[0287] wherein α SBFD represents the ratio of the first transmission number to the number of maximum transmission occasions of the first physical shared channel (i.e., the first coefficient).

[0288] In a second example, the terminal device can determine α non-SBFD In a case where α non-SBFDIn the case of α non-SBFD In the case of α

[0289] In the case of α non-SBFD represents the ratio of the second transmission times to the number of maximum transmission occasions of the first physical shared channel (i.e., the second coefficient).

[0290] In the third example, the terminal device can determine α SBFD and α non-SBFD In the case of α SBFD In the case of α bob-SBFD In the case of α

[0291] It can be understood that the first preset rule can also be described as follows: the first preset rule can include one or more of the following: in the case of the first transmission times being greater than the second transmission times (or the second transmission times being less than the first transmission times), the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit; or in the case of the first transmission times being less than the second transmission times (or the second transmission times being greater than the first transmission times), the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0292] For the second preset rule, the second preset rule can include one or more of the following: in the case of the ratio of the third product to the first value being greater than 1 / 2 (or the ratio of the fourth product to the first value being less than 1 / 2), the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit; or in the case of the ratio of the fourth product to the first value being greater than 1 / 2 (or the ratio of the third product to the first value being less than 1 / 2), the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0293] The third product is the product of the first transmission times and the number of resource blocks associated with the first physical shared channel transmission on the first type time unit.

[0294] The third product can be understood as N SBFDThe total number of resource blocks associated with the first physical shared channel transmission, for example, is the number of resource blocks associated with one first physical shared channel transmission. For example, N SBFD The total number of resource blocks associated with the first physical shared channel transmission is the number of resource blocks associated with one first physical shared channel transmission.

[0295] For example, the third product can satisfy the following formula:

[0296] The fourth product is the product of the second transmission number and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0297] The fourth product can be understood as N nob-SBFD The total number of resource blocks associated with the first physical shared channel transmission, for example, is the number of resource blocks associated with one first physical shared channel transmission. For example, N non-SBFD The total number of resource blocks associated with the first physical shared channel transmission is the number of resource blocks associated with one first physical shared channel transmission.

[0298] For example, the fourth product can satisfy the following formula:

[0299] The first value is the sum of the third product and the fourth product.

[0300] For example, the first value can satisfy the following formula:

[0301] In the first example, the terminal device can determine β SBFD In the case of β SBFD > 1 / 2, the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit; or in the case of β SBFD <1 / 2, the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0302] The ratio of the third product to the first value is β SBFD The ratio of the third product to the first value is β SBFD The first value can satisfy the following formula:

[0303] In the second example, the terminal device can determine β non-SBFD In the case of β non-SBFD > 1 / 2, the size of the first transmission block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type time unit; or in the case of βnon-SBFD In the case of β

[0304] wherein β non-SBFD is a ratio of the fourth product to the first value, β non-SBFD may satisfy the following formula:

[0305] In the third example, the terminal device can determine β SBFD and β non-SBFD In the case of β SBFD > 1 / 2, the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit; or in the case of β non-SBFD > 1 / 2, the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0306] For the third preset rule, the third preset rule includes one or more of the following: in the case that the first valid transmission occasion of the first physical shared channel is located in the first type time unit, the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit; or in the case that the first valid transmission occasion of the first physical shared channel is located in the second type time unit, the size of the first transport block is determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0307] It can be understood that the number of transmission occasions of the first physical shared channel is greater than or equal to 2, and the terminal device can determine in which type of time unit the first valid transmission occasion of the first physical shared channel is located, for example, when the first valid transmission occasion is located in the first type time unit, the size of the first transport block can be determined according to the number of resource blocks associated with the first physical shared channel transmission on the first type time unit; or when the first valid transmission occasion is located in the second type time unit, the size of the first transport block can be determined according to the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0308] Based on the second possible embodiment, the size of the first transmission block can be determined by using a predefined time unit type, or by the ratio of a third or fourth product to a first value, or by the ratio of different transmission counts to the maximum number of transmission opportunities on the first physical shared channel. This reduces computational complexity, simplifies implementation, and reduces the workload of the device. Furthermore, determining the size of the first transmission block according to a first, second, or third preset rule can save signaling overhead. Based on the first possible design, the terminal device can determine the number of resource blocks allocated for the first physical shared channel transmission (which can be denoted as n). RB That is, the number of resource blocks can be the number of resource blocks associated with the first physical shared channel transmission in the first type of time unit, the number of resource blocks associated with the first physical shared channel transmission in the second type of time unit, or a weighted average of the number of resource blocks associated with the first physical shared channel transmission in the first type of time unit and the number of resource blocks associated with the first physical shared channel transmission in the second type of time unit; furthermore, the terminal device can determine the number of REs (i.e., N) allocated for the first physical shared channel transmission based on the number of resource blocks. RE =min(156,N′) RE )*n RB The number of REs can be used to determine intermediate variables, and quantization values ​​can be obtained by quantizing the intermediate variables. The size of the first transport block can then be determined based on the quantization values.

[0309] Where, N′ RE The number of REs used for transmitting the first physical shared channel in a resource block is specified in S401 above. RE The determination of [the specific details] will not be elaborated upon here.

[0310] The intermediate variables can be referred to in the description of intermediate variables in S402 above, and will not be repeated here. Based on the description of the first and second transmission counts in the first possible design, this application proposes two methods for determining the first and second transmission counts:

[0311] Method 1: The terminal device can determine the first transmission count and the second transmission count based on the physical timeslot count.

[0312] When counting physical time slots, it is not necessary to consider whether the time slot / symbol can be used for transmission on the first physical shared channel. For example, regardless of whether the link direction of the time slot / symbol is consistent with the transmission direction of the first physical shared channel, the time slot / symbol is determined to be used for transmission on the first physical shared channel.

[0313] Specifically, the first transmission number can be determined according to the number of maximum transmission occasions of the first physical shared channel and the first type of time unit, and the second transmission number can be determined according to the number of maximum transmission occasions of the first physical shared channel and the second type of time unit.

[0314] Wherein, the terminal device can determine the starting position and the ending position of each first physical shared channel transmission in the time domain, and can determine the transmission number of the first physical shared channel transmission in different types of time units according to the type of the time unit corresponding to the starting position to the ending position.

[0315] For example, taking the number of maximum transmission occasions of the first physical shared channel as 10, the initial values of the first transmission number and the second transmission number are both 0, the terminal device can determine the starting position (such as T0) and the ending position (such as T1) of the first physical shared channel transmission in the time domain, and then can determine the type of the time unit corresponding to T0 to T1 (it can be understood as the type of the time unit in T0 to T1), if T0 to T1 corresponds to the first type of time unit, the first transmission number is incremented by 1; if T0 to T1 corresponds to the second type of time unit, the second transmission number is incremented by 1; the terminal device can determine the starting position (i.e. T1) of the second physical shared channel transmission in the time domain according to the ending position (such as T1) of the first physical shared channel transmission, and determine the ending position (such as T2) of the second physical shared channel transmission in the time domain, and then can determine the type of the time unit corresponding to T1 to T2, if T1 to T2 corresponds to the first type of time unit, the first transmission number is incremented by 1; if T1 to T2 corresponds to the second type of time unit, the second transmission number is incremented by 1; in this way, the terminal device can determine the starting position (such as T9) and the ending position (such as T10) of the tenth first physical shared channel transmission in the time domain, and then can determine the type of the time unit corresponding to T9 to T10, if T9 to T10 corresponds to the first type of time unit, the first transmission number is incremented by 1; if T9 to T10 corresponds to the second type of time unit, the second transmission number is incremented by 1; the counting ends, and the final result of the counting of the first transmission number and the second transmission number is the first transmission number and the second transmission number.

[0316] Wherein, the starting position of the first first physical shared channel transmission in the time domain is configured by the network device.

[0317] Based on the description of the first mode, when determining the first transmission number and the second transmission number, whether the time slots / symbols can be used for the first physical shared channel transmission does not need to be considered, which can reduce the calculation complexity, simplify the implementation, and reduce the workload of the device.

[0318] The second mode, the terminal device can determine the first transmission number and the second transmission number according to the available time slot count.

[0319] The terminal device can determine whether the transmission occasion can be used for transmitting the first physical shared channel according to whether the transmission occasion is valid.

[0320] Specifically, the first transmission number and the second transmission number can be determined according to the number of maximum transmission occasions of the first physical shared channel and one or more of the following: the first configuration information, the second configuration information, or the first preset criterion.

[0321] The first configuration information can be referred to as SBFD subband time / frequency location indication. The first configuration information is used to configure one or more of the following: time domain location of the uplink or downlink subband in the first type of time unit, frequency domain location of the uplink or downlink subband in the first type of time unit.

[0322] The second configuration information can be referred to as link direction indication. The second configuration information is used to indicate the link direction of one or more first type of time units.

[0323] The first preset criterion is used to instruct the device to determine the link direction of one or more first type of time units.

[0324] It can be understood that the terminal device can determine the link direction of the transmission occasion according to one or more of the above configuration information.

[0325] For example, the first configuration information can indicate the time-frequency domain location of the uplink subband or the downlink of the first type of time unit. When the transmission occasion is located in the time-frequency domain location of the uplink subband of the first type of time unit, the terminal device can determine that the link direction of the transmission occasion is uplink. When the transmission occasion is located in the time-frequency domain location of the downlink subband of the first type of time unit, the terminal device can determine that the link direction of the transmission occasion is downlink.

[0326] For another example, the second configuration information can indicate the link direction of a symbol or a slot. The terminal device can determine the link direction of the transmission occasion located in the symbol or the slot.

[0327] For another example, the terminal device can determine the link direction of a symbol or a slot according to the first preset criterion, and then can determine the link direction of the transmission occasion located in the symbol or the slot.

[0328] Further, the terminal device can determine whether to count the first transmission number or the second transmission number according to whether the link direction of the transmission occasion is consistent with the direction of the first physical shared channel. For example, when the link direction of the transmission occasion is the same as the direction of the first physical shared channel, the transmission occasion can be regarded as a valid transmission occasion. If the valid transmission occasion is located in the first type of time unit, the first transmission number can be counted, that is, the first transmission number is incremented by 1. If the valid transmission occasion is located in the second type of time unit, the second transmission number can be counted, that is, the second transmission number is incremented by 1. When the link direction of the transmission occasion is different from the direction of the first physical shared channel, it can be determined whether the link direction of the next transmission occasion is the same as the direction of the first physical shared channel. If so, the transmission number is determined to be a valid transmission number, and the counting operation is performed. In this way, the number of valid transmission occasions is determined to be the number of maximum transmission occasions, and the counting is ended. The final results of the first transmission number and the second transmission number are the first transmission number and the second transmission number.

[0329] Optionally, the first transmission number and the second transmission number can also be determined according to one or more of the following: third configuration information, fourth configuration information, or fifth configuration information.

[0330] 1) Third configuration information

[0331] The third configuration information can be referred to as TDD uplink-downlink common configuration (TDD-UL-DL-ConfigurationCommon).

[0332] The third configuration information is used to configure a time division duplex TDD uplink-downlink configuration common to cells.

[0333] It can be understood that the terminal device can determine the time-frequency resources of the network device for transmitting the first physical downlink shared channel and the time-frequency resources of the network device for receiving the first physical uplink shared channel according to the third configuration information.

[0334] For example, the terminal device can determine whether the link direction of the transmission occasion is consistent with the direction of the first physical shared channel according to whether the transmission occasion is located in the time-frequency resource of the first physical downlink shared channel or the time-frequency resource of the first physical uplink shared channel, and then determine whether to count the first transmission number or the second transmission number. For example, taking the first physical shared channel as the first physical downlink shared channel, when the terminal device determines that the transmission occasion is located in the time-frequency resource of the first physical downlink shared channel, it can be determined that the link direction of the transmission occasion is consistent with the direction of the first physical downlink shared channel, and the transmission occasion can be regarded as a valid transmission occasion. If the valid transmission occasion is located in the first type of time unit, the first transmission number can be counted, that is, the first transmission number is incremented by 1. If the valid transmission occasion is located in the second type of time unit, the second transmission number can be counted, that is, the second transmission number is incremented by 1. When the terminal device determines that the transmission occasion is located in the time-frequency resource of the first physical uplink shared channel, it can be determined that the link direction of the transmission occasion is not consistent with the direction of the first physical downlink shared channel. It can be determined whether the link direction of the next transmission occasion is located in the time-frequency resource of the first physical downlink shared channel, and whether the link direction of the transmission occasion is consistent with the direction of the first physical shared channel. Then it can be determined whether to count the first transmission number or the second transmission number. Similarly, until the number of valid transmission occasions is equal to the number of maximum transmission occasions, the counting is ended, and the final result of the first transmission number and the second transmission number is the first transmission number and the second transmission number.

[0335] 2), fourth configuration information

[0336] The fourth configuration information can be referred to as TDD uplink-downlink dedicated configuration (TDD-UL-DL-ConfigurationDedicated).

[0337] The fourth configuration information is used to configure the TDD uplink-downlink configuration dedicated to the terminal device.

[0338] It can be understood that the terminal device can determine the time-frequency resource of the terminal device sending the first physical uplink shared channel and the time-frequency resource of the network device receiving the first physical downlink shared channel according to the third configuration information.

[0339] The specific examples of determining the first transmission number and the second transmission number according to the fourth configuration information can refer to the examples of the third configuration information described above, and will not be described here.

[0340] 3), fifth configuration information

[0341] The fifth configuration information can be referred to as SSB burst position (SSB-PositionsInBurst).

[0342] The fifth configuration information is used for configuring a time domain position of a synchronization signal / physical broadcast channel block (SSB) transmitted in a half frame of one SSB.

[0343] It can be understood that when the first physical shared channel is a first physical uplink shared channel, the terminal device can determine the starting position and the ending position of the first physical uplink shared channel transmission, and can determine whether there is an SSB in the starting position to the ending position of the first physical uplink shared channel transmission according to the fifth configuration information. If there is, the starting position and the ending position of the first physical uplink shared channel transmission are re-determined. Otherwise, the first transmission number or the second transmission number can be incremented by 1.

[0344] Based on the description of the second mode, the terminal device can determine whether the slot / symbol can be used for the first physical shared channel transmission based on one of the configuration information, or can determine whether the slot / symbol can be used for the first physical shared channel transmission in combination with the above-mentioned multiple configuration information, which is not limited.

[0345] Based on the description of the second mode, whether the slot / symbol can be used for the first physical shared channel transmission can be considered when determining the first transmission number and the second transmission number, which can improve the accuracy of determining the first transmission number and the second transmission number, and can improve the reliability of communication.

[0346] It can be understood that the above-mentioned manner of the terminal device determining the first transmission number and the second transmission number can also be applicable to the network device determining the first transmission number and the second transmission number, which is not repeated here.

[0347] Different from the above-mentioned first possible design of determining the size of the first transport block in the case that the multiple transmissions of the first physical shared channel correspond to the multiple repeated transmissions of the first transport block, with reference to the following second possible design, the terminal device can also determine the size of the first transport block in the case that the multiple transmissions of the first physical shared channel correspond to the mapping of the first transport block to multiple slots, which is specifically described as follows:

[0348] The size of the first transport block can be determined according to the first transmission number, the second transmission number, the number of resource blocks associated with the first physical shared channel transmission on the first type time unit, and the number of resource blocks associated with the first physical shared channel transmission on the second type time unit.

[0349] The first transmission number and the second transmission number can refer to the above-mentioned description of the first transmission number and the second transmission number, which is not repeated here.

[0350] Specifically, the terminal device can determine the size of the first transport block by determining the total number of resource blocks (i.e., the third resource block number) occupied by the first physical shared channel on the multiple slots.

[0351] wherein the third number of resource blocks can be a sum of the first product and the fourth product.

[0352] wherein the third product is a product of the first number of transmissions and a number of resource blocks associated with the first physical shared channel transmission on the first type of time unit. For example, the third product can satisfy the following equation:

[0353] wherein the fourth product is a product of the second number of transmissions and a number of resource blocks associated with the first physical shared channel transmission on the second type of time unit. For example, the fourth product can satisfy the following equation:

[0354] For example, the third number of resource blocks can be a sum of the first product and the fourth product, and the third number of resource blocks can satisfy the following equation:

[0355] wherein N SBFD represents the first number of transmissions, N non-SBFD represents the second number of transmissions, represents a number of resource blocks associated with the first physical shared channel transmission on the first type of time unit, represents a number of resource blocks associated with the first physical shared channel transmission on the second type of time unit.

[0356] Based on the second possible design, the terminal device can determine a total number of resource blocks (i.e., the third number of resource blocks, which can be denoted as The terminal device can determine a number of REs (i.e., the number of REs, which can be denoted as ) for the first physical shared channel transmission in the plurality of time slots according to the third number of resource blocks, determine an intermediate variable according to the number of REs, and obtain a quantization value by quantizing the intermediate variable, and determine the size of the first transport block according to the quantization value.

[0357] Different from the above two possible designs, with reference to a third possible design described below, the size of the first transport block can also be determined in a scenario where the first physical shared channel is mapped to a plurality of time slots and Y times of repeated transmissions for the first transport block (such as the scenario shown in FIG. 16), and the third possible design is described in detail as follows:

[0358] The size of the first transport block can be determined according to the total number of resource blocks in the xth repeated transmission (x is a positive integer less than or equal to Y) (for example, the size of the first transport block can be determined according to the total number of resource blocks in the first repeated transmission), or the first transport block can be determined according to Y second resource block numbers, wherein the yth second resource block number in the Y second resource block numbers is the total number of resource blocks in the yth repeated transmission, y = 1, 2, …, Y. Two possible implementations are proposed in the present application:

[0359] In a first possible implementation, the size of the first transport block can be determined according to the total number of resource blocks in the xth repeated transmission (x is a positive integer less than or equal to Y).

[0360] Specifically, the total number of resources in the xth repeated transmission can be determined according to the xth third transmission number, the xth fourth transmission number, the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit in the xth repeated transmission, and the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit in the xth repeated transmission.

[0361] The xth third transmission number is the number of times of transmission of the first physical shared channel on the first type of time unit in the xth repeated transmission of the first transport block.

[0362] The xth fourth transmission number is the number of times of transmission of the first physical shared channel on the second type of time unit in the xth repeated transmission of the first transport block.

[0363] For example, the total number of resources in the xth repeated transmission can be the sum of the fifth product and the sixth product. The fifth product is the product of the xth third transmission number and the number of resource blocks associated with the first physical shared channel transmission on the first type of time unit in the xth repeated transmission; the sixth product is the product of the xth fourth transmission number and the number of resource blocks associated with the first physical shared channel transmission on the second type of time unit in the xth repeated transmission.

[0364] For example, the total number of resources in the xth repeated transmission can satisfy the following formula: wherein, N x represents the total number of resources in the xth repeated transmission, N SBFD x N x represents the xth third transmission number, N non-SBFD x N x represents the xth fourth transmission number, N x represents the number of resource blocks for transmitting the physical shared channel on the first type of time unit in the xth repeated transmission, indicates a number of resource blocks used for transmitting the physical shared channel on the second type time unit in the xth repetition transmission.

[0365] It can be understood that the fifth product can be expressed as: The sixth product can be expressed as:

[0366] Based on the first possible implementation, the terminal device can determine the total number of resource blocks in the xth repetition transmission (which can be denoted as ), can determine the number of REs allocated for the first physical shared channel transmission according to the total number of resource blocks in the xth repetition transmission (i.e. ), can determine an intermediate variable according to the number of REs, and obtain a quantization value by quantizing the intermediate variable, and determine the size of the first transport block according to the quantization value. Wherein, x can be indicated or configured by the base station, or can be predefined, for example, x takes a default value of 1, that is, the resource block number of the first repetition transmission is determined by default.

[0367] Based on the first possible implementation, the xth third transmission number and the xth fourth transmission number can be determined based on the following two ways:

[0368] Way one, the terminal device can determine the xth third transmission number and the xth fourth transmission number according to the physical slot count.

[0369] Specifically, the xth third transmission number is determined according to the number of maximum transmission occasions of the first physical shared channel in the xth repetition transmission and the first type time unit; the xth fourth transmission number is determined according to the number of maximum transmission occasions of the first physical shared channel in the xth repetition transmission and the second type time unit.

[0370] Wherein, the specific way of determining the xth third transmission number and the xth fourth transmission number can refer to the content of determining the first transmission number and the second transmission number based on the way one described above, which will not be repeated here.

[0371] Way two, the terminal device can determine the xth third transmission number and the xth fourth transmission number according to the available slot count.

[0372] Specifically, the xth third transmission number and the xth fourth transmission number can be determined according to the number of maximum transmission occasions of the first physical shared channel and one or more of the following: the first configuration information, the second configuration information, or the first preset criterion.

[0373] The first configuration information, the second configuration information, and the first preset criterion can refer to the descriptions of the first configuration information, the second configuration information, or the first preset criterion, which will not be repeated here.

[0374] Optionally, the xth third transmission number and the xth fourth transmission number can also be determined according to one or more of the following: the third configuration information, the fourth configuration information, or the fifth configuration information.

[0375] The third configuration information, the fourth configuration information, and the fifth configuration information can refer to the descriptions of the third configuration information, the fourth configuration information, or the fifth configuration information, which will not be repeated here.

[0376] The specific manner of determining the xth third transmission number and the xth fourth transmission number can refer to the content of determining the first transmission number and the second transmission number based on the second manner, which will not be repeated here.

[0377] In a second possible implementation, the size of the first transport block can be determined according to Y second resource block numbers.

[0378] The yth second resource block number in the Y second resource block numbers can be determined according to the yth third transmission number, the yth fourth transmission number, the number of resource blocks used for transmitting the physical shared channel in the first type time unit in the yth repeated transmission, and the number of resource blocks used for transmitting the physical shared channel in the second type time unit in the yth repeated transmission.

[0379] The yth third transmission number can refer to the description of the xth third transmission number, which will not be repeated here.

[0380] The yth fourth transmission number can refer to the description of the xth fourth transmission number, which will not be repeated here.

[0381] For example, the yth second resource block number can be determined according to a seventh product and an eighth product, i.e., the yth second resource block number can be the sum of the seventh product and the eighth product, wherein the seventh product is the product of the yth third transmission number and the number of resource blocks associated with the first physical shared channel transmission in the first type time unit in the yth repeated transmission; and the eighth product is the product of the yth third transmission number and the number of resource blocks associated with the first physical shared channel transmission in the second type time unit in the yth repeated transmission.

[0387] Based on the second possible implementation, the terminal device can determine the average of the Y second resource block numbers (which can be denoted as n RB ), the number of REs allocated for the first physical shared channel transmission (i.e. ) can be determined according to the average of the Y second resource block numbers, the intermediate variable can be determined according to the number of REs, and the quantization value can be obtained by quantizing the intermediate variable, and the size of the first transport block can be determined according to the quantization value.
