[0003] This application belongs to the field of communication technology, and specifically relates to a channel transmission method, apparatus, device, and readable storage medium. Background Technology

[0004] In related technologies, in order to improve the coverage of broadcast information, low-order modulation methods are usually used, and the transport block size (TBS) of the physical downlink shared channel (PDSCH) used to carry the broadcast information is limited.

[0005] However, with the development of communication systems, more application scenarios and more terminal types may emerge, requiring more information to be broadcast. Therefore, how to support the transmission of large-sized information is an urgent problem to be solved.

[0006] In addition, for narrowband communication scenarios, such as the Internet of Things (IoT), it is necessary to consider the deployment requirements of a narrow minimum bandwidth and the scenario of coexistence with broadband communication with a large bandwidth. In this case, how to transmit relatively large amounts of information under narrow bandwidth is also a problem. Summary of the Invention

[0133] Figure 1 shows a block diagram of a wireless communication system applicable to an embodiment of this application.

The term "base station" is not limited to any specific technical term. It should be noted that the embodiments of this application only use the base station in the NR system as an example for introduction, and do not limit the specific type of base station.

[0136] To facilitate understanding of the embodiments of this application, the system information related to this application is described.

[0137] In NR systems, system information can include Minimum System Information (MSI), Remaining System Information (RMSI), and Other System Information (OSI). These three types of system information can be divided into one Master Information Block (MIB) and nine System Information Blocks (SIBs). MIB information is transmitted via the Broadcast Channel (BCH) and the Physical Broadcast Channel (PBCH), while SIBs are transmitted via the DL-SCH and the Physical Downlink Shared Channel (PDSCH). RMSI includes SIB1, and OSI includes SIB2 through SIB9. MIBs and SIB1 each have their own Radio Resource Control (RRC) messages.

[0138] SIB1 includes the necessary information for the terminal to camp on the cell, such as cell selection information, Public Land Mobile Network (PLMN), Tracking Area Code (TAC), cell identifier, RAN notification information, SI scheduling information for OSI, and serving cell information.

[0139] The Physical Downlink Control Channel (PDCCH) is the only downlink control channel in the NR system. The PDCCH carries downlink control information (DCI). DCI mainly includes resource scheduling information for transmission via the PDSCH or Physical Uplink Shared Channel (PUSCH), as well as uplink power control indications, time slot format indications, and information on which physical resource blocks (PRBs) and orthogonal frequency-division multiplexing (OFDM) symbols are not mapped to data. After a series of scrambling, modulation, and coding processes, the DCI is mapped to physical resources in units of Control Channel Elements (CCEs).

[0140] The PDCCH dynamically sends the DCI to the UE. The terminal needs to read this control information to know the time-domain and frequency-domain resources of the PDSCH and the demodulation / decoding method of the PDSCH, or the time-domain and frequency-domain resources of the PUSCH and the assembly method of the PUSCH.

[0141] To facilitate understanding of the embodiments of this application, the DCI format related to this application will be described.

[0142] Different DCI formats can be defined for different downlink control information sizes.

[0143] To limit the complexity of terminal detection of PDCCH candidates, the NR system limits the DCI size detected in each time slot to no more than 4 types. Among them, the Cell Radio Network Temporary Identity (C-RNTI) used by the DCI is limited to no more than 3 types, and other RNTIs are limited to no more than one type.

[0144] Taking DCI 1-0 as an example, the content of DCI will be explained.

[0145] DCI format 1_0 is used to allocate downlink resources for PDSCH. DCI format 1_0 is a fallback DCI. For SI-RNTI's DCI 1-0, it may include the following fields:

[0146] Frequency Domain Resource Assignment (FDRA) domain;

[0147] Time Domain Resource Assignment (TDRA) domain;

[0148] The Virtual Resource Block (VRB) to PRB mapping field;

[0149] Modulation and Coding Scheme (MCS) domain;

[0150] Redundancy Version (RV) domain;

[0151] System Information Indicator field.

[0152] The TDRA field can indicate the row index in the TDRA table. The terminal can determine the time domain resources allocated to the PDSCH based on the indication of the TDRA field and the TDRA table. Table 1 shows an example of a TDRA table.

[0153] Table 1

[0154] Here, dmrs-TypeA-Position indicates the position of the first symbol of DMRS when using PDSCH mapping type A, for example, the value can be 2 or 3.

[0155] The PDSCH mapping type indicates the PDSCH mapping type, which can include type A and type B. The reference point of l defined by type A is the start symbol of the time slot, while the reference point of l defined by type B is the first symbol of the time domain resource scheduled to PDSCH.

[0156] K0 represents the time-domain interval between PDCCH and PDSCH. K0 = 0 means that PDCCH and PDSCH are in the same time slot, and K0 = 1 means that PDSCH is in the next time slot of PDCCH.

[0157] S indicates the start symbol of PDSCH;

[0158] L represents the duration of PDSCH.

[0159] In related technologies, when a cell transmits SIB1, in order to cover the entire cell, the PDSCH carrying the SIB1 can only use Quadrature Phase Shift Keying (QPSK) modulation. This indirectly limits the Transport Block Size (TBS) of the PDSCH carrying the SIB1. Furthermore, to ensure that the cell can cover the entire cell when transmitting SIB1, the protocol additionally requires that the TBS of the PDSCH carrying the SIB1 cannot exceed 2976. Since SIB1 contains the necessary information for the terminal to camp in the cell, it is indispensable for ensuring the terminal camps in the cell and for subsequent random access to proceed smoothly.

[0160] However, future mobile communication systems may present more diverse scenarios and a wider range of terminal types, potentially leading to larger SIB1 values. For instance, the emergence of new scenarios and applications, or the need to support more terminal types from low-end to high-end, may necessitate the transmission of more information within system information (such as SIB1). Consequently, the TBS of the PDSCH carrying SIB1 may become larger. Therefore, how to transmit large-size broadcast information is a pressing issue that needs to be addressed.

[0161] In addition, for narrowband communication, such as Internet of Things (IoT) scenarios, it is necessary to consider the deployment requirements of narrow minimum bandwidth and its coexistence with broadband communication with large bandwidth. In this case, how to transmit relatively large amounts of information under narrow bandwidth is also a problem.

[0162] The channel transmission method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

For example, the first physical downlink channel may include a first transport block (TB), which is used to carry first information, and the first TB can be transmitted through multiple resource units.

[0182] In other embodiments of this application, the target physical downlink channel includes a plurality of second physical downlink channels, each second physical channel being transmitted through a resource unit, and the first information being carried in the plurality of second physical downlink channels.

[0183] That is, these multiple second physical downlink channels can be transmitted through multiple resource units.

[0184] Optionally, the plurality of resource units may include one or a combination of multiple time-domain units, multiple frequency-domain units, and multiple spatial-domain units.

[0185] In one specific embodiment, the different second physical downlink channels among the plurality of second physical downlink channels may correspond to different time domain units and / or different frequency domain units and / or different spatial domain units. That is, the plurality of second physical downlink channels may be time-division and / or frequency-division and / or space-division.

[0186] In another specific embodiment, each of the plurality of second physical downlink channels includes a second TB, and the plurality of second TBs in the plurality of second physical downlink channels are used to carry first information. The plurality of second TBs can be transmitted through a plurality of resource units. For example, different second TBs in the plurality of second TBs can correspond to different time domain units and / or different frequency domain units and / or different spatial domain units, that is, the plurality of second TBs can be time-division and / or frequency-division and / or space-division.

[0187] In some embodiments of this application, before the terminal receives the target physical downlink channel from the first network-side device through multiple resource elements, the method 200 further includes:

[0188] The terminal determines the transmission mode of the target physical downlink channel, wherein the transmission mode of the target physical downlink channel is one of the following transmission modes:

[0189] In the first transmission mode, the first information is transmitted through a physical downlink channel, and the physical downlink channel is transmitted through a time domain unit.

[0190] In the second transmission mode, the first information is transmitted through a physical downlink channel, and the physical downlink channel is transmitted through multiple resource units.

[0191] In the third transmission mode, the first information is transmitted through multiple physical downlink channels, and the multiple physical downlink channels are transmitted through multiple resource units.

[0192] In some embodiments, the terminal receives a target physical downlink channel from a first network-side device through multiple resource elements, including:

[0193] When the terminal determines that the transmission mode of the target physical downlink channel is the second transmission mode or the third transmission mode, the terminal receives the target physical downlink channel from the first network-side device through multiple resource units. When the terminal determines that the transmission mode of the target physical downlink channel is the second transmission mode or the third transmission mode, the terminal can understand that the same information is being transmitted on the multiple resource units. Therefore, the terminal can merge the target physical downlink channels received on the multiple resource units to obtain the information sent to the terminal by the first network-side device.

[0194] In other embodiments, the method 200 further includes:

[0195] When the terminal determines that the transmission mode of the target physical downlink channel is the first transmission mode, the terminal receives the target physical downlink channel from the first network-side device through a resource unit.

[0196] Optionally, the plurality of resource units may include at least one of a plurality of time-domain units, a plurality of frequency-domain units, and a plurality of spatial-domain units.

[0197] Optionally, for broadband communication scenarios, the target physical downlink channel can be transmitted using the first transmission mode, the second transmission mode, or the third transmission mode.

[0198] Optionally, for narrowband communication scenarios, the target physical downlink channel can be transmitted using either the second or third transmission mode.

[0199] It should be noted that in some embodiments, the transmission mode of the target physical downlink channel may also employ a combination of at least two of the above transmission modes. For example, the transmission mode of the target physical downlink channel may be a combination of the second and third transmission modes; that is, the target physical downlink channel may include multiple physical downlink channels, and each physical downlink channel may be transmitted through multiple resource elements. Specifically, for example, the target physical downlink channel may include multiple physical downlink channels, and each physical downlink channel may be transmitted through multiple time-domain elements or multiple codewords.

[0200] In some embodiments, when the target physical downlink channel is transmitted using a first transmission mode, the target physical downlink channel may include a first physical downlink channel, which can be transmitted through a time domain unit.

[0201] In this case, the first physical downlink channel may include a first TB, which carries first information and is transmitted through a time-domain unit. Optionally, within this time-domain unit, the first TB may be transmitted through a layer.

[0202] Optionally, a time-domain unit can be a time slot.

[0203] That is, in the first transmission mode, the first TB can be transmitted within a time slot. In this case, the target physical downlink channel can adopt the existing PDSCH transmission method.

[0204] In some embodiments, when the target physical downlink channel is transmitted using a second transmission mode, the target physical downlink channel may include a first physical downlink channel, which may be transmitted through multiple resource units.

[0205] In this case, the first physical downlink channel may include a first TB, which is used to carry first information, and the first TB is transmitted through multiple resource units. These multiple resource units may include at least one of multiple time-domain units, multiple frequency-domain units, and multiple spatial-domain units.

[0206] Therefore, in the embodiments of this application, a large-size TB (i.e., the first TB) used to carry the first information can be transmitted through multiple time domain units and / or multiple frequency domain units and / or multiple spatial domain units, thereby achieving the purpose of transmitting large-size first information or transmitting relatively large first information in the case of narrow bandwidth.

[0207] As an example of a sub-mode of the second transmission mode (denoted as the first sub-mode), the physical downlink channel can be transmitted through multiple spatial units. Optionally, these multiple spatial units may include, but are not limited to, multiple codewords. For example, when the target physical downlink channel is transmitted using this first sub-mode, the first physical downlink channel is transmitted through multiple codewords. In this case, the first sub-mode is also called the multi-codeword PDSCH transmission mode, that is, the first sub-mode supports spatial multiplexing transmission.

[0208] Therefore, in this embodiment of the application, a large-size TB (i.e., the first TB) used to carry the first information can be transmitted through multiple spatial units (e.g., multiple codewords), thereby enabling the transmission of large-size first information or the transmission of relatively large first information in the case of narrow bandwidth.

[0209] As an example of another sub-mode of the second transmission mode (denoted as the second sub-mode), the physical downlink channel can be transmitted through multiple time-domain units. For example, when the target physical downlink channel is transmitted using this second sub-mode, the first physical downlink channel is transmitted through multiple time-domain units; that is, the first TB can be mapped to multiple time-domain units, or in other words, the TB mapped to these multiple time-domain units corresponds to one physical downlink channel. This second sub-mode is also called the cross-time-domain unit PDSCH transmission mode or the multi-time-domain unit PDSCH transmission mode. When the time-domain unit is a timeslot, this second sub-mode can also be called the TB processing over multiple slots (TBoMS) mode.

[0210] Therefore, in this embodiment of the application, a large-size TB (i.e., the first TB) used to carry the first information can be transmitted through multiple time domain units (e.g., multiple time slots), thereby enabling the transmission of large-size first information or the transmission of relatively large first information in the case of narrow bandwidth.

[0211] In some embodiments, when the target physical downlink channel is transmitted via a third transmission mode, the target physical downlink channel may include a plurality of second physical downlink channels, which may be transmitted via a plurality of resource units. For example, each second physical downlink channel may include a second TB, each second TB being transmitted via a resource unit, and the plurality of second TBs in the plurality of second physical downlink channels being used to transmit first information.

[0212] Therefore, in this embodiment of the application, the large TB used to carry the first information can be divided into multiple small TBs (i.e., second TBs). In this way, each second TB can be transmitted through a physical downlink channel. For each physical downlink channel, the existing PDSCH transmission method can be adopted.

[0213] As an example of a sub-mode of the third transmission mode, the plurality of physical downlink channels can be transmitted through multiple time-domain units. For example, when the target physical downlink channel is transmitted using this sub-mode, the plurality of second physical downlink channels are transmitted through multiple time-domain units, that is, the plurality of second TBs can be mapped onto multiple time-domain units, such as multiple time slots.

[0214] Therefore, in this embodiment of the application, the large-size TB used to carry the first information can be divided into multiple smaller-size TBs (i.e., second TBs), and the multiple TBs can be transmitted through multiple time slots, thereby enabling the transmission of large-size first information or the transmission of relatively large first information in the case of narrow bandwidth through multi-time slot PDSCH transmission.

[0215] In the embodiments of this application, the third transmission mode is also called the Multiple-PDSCH transmission mode.

[0216] Optionally, for the third transmission mode, the plurality of second physical downlink channels may be scheduled by a single DCI, or may be scheduled by multiple DCIs, for example, each DCI is used to schedule one second physical downlink channel.

[0217] Optionally, the Radio Network Temporary Identity (RNTI) used by the DCI for scheduling the second physical downlink channel (i.e., Multiple-PDSCH) of the third transmission mode can be different from the RNTI used by the DCI for scheduling Single-PDSCH.

[0218] As an example and not a limitation, the cyclic redundancy check (CRC) of the DCI used for scheduling Single-PDSCH can be scrambled using SI-RNTI, and the CRC of the DCI used for scheduling Multiple-PDSCH can be scrambled using SI-MultiDCI-RNTI. The name SI-MultiDCI-RNTI is only an example and can be replaced with other names. This application does not limit this.

[0219] Optionally, the DCI used for scheduling the second physical downlink channel (i.e., Multiple-PDSCH) of the third transmission mode and the DCI used for scheduling the single-PDSCH can adopt the same format, for example, distinguished by a specific field or specific bit in the DCI. Alternatively, the DCI used for scheduling the second physical downlink channel (i.e., Multiple-PDSCH) of the third transmission mode and the DCI used for scheduling the single-PDSCH can also adopt different formats.

[0220] It should be noted that, in the embodiments of this application, the first network-side device may indicate to the terminal, either explicitly or implicitly, the transmission mode adopted by the target physical downlink channel carrying the first information, and this application does not limit this.

[0221] In some embodiments, the transmission mode of the target physical downlink channel can be indicated by at least one of the following methods:

[0222] A specific control resource set (CORESET);

[0223] Specific search space;

[0224] Specific physical downlink control channel (PDCCH) monitoring timing (Monitor Occasion, MO);

[0225] Specific Radio Network Temporary Identifier (RNTI);

[0226] Specific frequency domain resources;

[0227] Information in the main information block (MIB);

[0228] The payload in the Physical Broadcast Channel (PBCH), such as the values ​​of some bits in the L1 payload;

[0229] Information related to the Synchronization Signal Block (SSB);

[0230] Information about the reference signal related to the first information;

[0231] Broadcast information sent before the first information;

[0232] Downlink Control Information (DCI);

[0233] The first network-side device sends Radio Resource Control (RRC) signaling;

[0234] The Media Access Control (MAC) signaling sent by the first network-side device;

[0235] Signaling from the second network-side device.

[0236] In some embodiments, the transmission mode of the target physical downlink channel can be indicated by a specific CORESET. Correspondingly, the terminal can learn the transmission mode used by the first network-side device to transmit the target physical downlink channel through the specific CORESET.

[0237] Optionally, the specific CORESET may be the CORESET used by the DCI that schedules the target physical downlink channel.

[0238] Optionally, the CORESET used by the DCI for scheduling the target physical downlink channel and the transmission mode used by the target physical downlink channel can have a corresponding relationship. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0239] Therefore, the first network-side device can indicate the transmission mode of the target physical downlink channel to the terminal by using the CORESET of the DCI that schedules the target physical downlink channel. Correspondingly, the terminal can determine the transmission mode of the target physical downlink channel scheduled by the DCI by receiving the CORESET.

[0240] Optionally, the specific search space can be the search space used by the DCI that schedules the target physical downlink channel.

[0241] Optionally, the search space used by the DCI for scheduling the target physical downlink channel and the transmission mode used by the target physical downlink channel can have a corresponding relationship. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of the correspondence.

[0242] Therefore, the first network-side device can indicate the transmission mode of the target physical downlink channel to the terminal by using the search space used by the DCI to schedule the target physical downlink channel. Correspondingly, the terminal can determine the transmission mode used by the target physical downlink channel scheduled by the DCI by receiving the search space used by the DCI.

[0243] Optionally, the specific PDCCH MO can be the PDCCH MO used by the DCI that schedules the target physical downlink channel.

[0244] Optionally, the PDCCH MO used by the DCI for scheduling the target physical downlink channel and the transmission mode used by the target physical downlink channel can have a corresponding relationship. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0245] Therefore, the first network-side device can indicate the transmission mode of the target physical downlink channel to the terminal by scheduling the PDCCH MO used by the DCI of the target physical downlink channel. Correspondingly, the terminal can determine the transmission mode used by the target physical downlink channel scheduled by the DCI by receiving the PDCCH MO used by the DCI.

[0246] Optionally, the specific RNTI may be the RNTI used by the DCI that schedules the target physical downlink channel.

[0247] Optionally, the RNTI used by the DCI for scheduling the target physical downlink channel and the transmission mode used by the target physical downlink channel can have a corresponding relationship. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0248] For example, the first transmission mode corresponds to the first RNTI, and the second and third transmission modes correspond to the second RNTI. When the first network-side device uses the first transmission mode to transmit the target physical downlink channel, the CRC of the DCI of the target physical downlink channel can be scrambled with the first RNTI. When the first network-side device uses the second or third transmission mode to transmit the target physical downlink channel, the CRC of the DCI of the target physical downlink channel can be scrambled with the second RNTI.

[0249] For example, the first transmission mode corresponds to the first RNTI, the second transmission mode corresponds to the second RNTI, and the third transmission mode corresponds to the third RNTI. When the first network-side device uses the first transmission mode to transmit the target physical downlink channel, the CRC of the DCI of the target physical downlink channel can be scrambled using the first RNTI; when the first network-side device uses the second transmission mode to transmit the target physical downlink channel, the CRC of the DCI of the target physical downlink channel can be scrambled using the second RNTI; and when the first network-side device uses the third transmission mode to transmit the target physical downlink channel, the CRC of the DCI of the target physical downlink channel can be scrambled using the third RNTI.

[0250] Therefore, the first network-side device can indicate the transmission mode of the target physical downlink channel to the terminal by using the RNTI used by the DCI that schedules the target physical downlink channel. Correspondingly, the terminal can determine the transmission mode used by the target physical downlink channel scheduled by the DCI by receiving the RNTI used by the DCI.

[0251] Optionally, the specific frequency domain resources may be the frequency domain resources used by the first network-side device to schedule the DCI of the target physical downlink channel, or the frequency domain resources used by the first network-side device to transmit the target physical downlink channel. These frequency domain resources may include, but are not limited to, carrier, band, subband, BWP, etc.

[0252] Optionally, the DCI used by the first network-side device to schedule the target physical downlink channel or the frequency domain resources used by the first network-side device to transmit the target physical downlink channel may have a corresponding relationship with the transmission mode used by the target physical downlink channel. Optionally, this correspondence may be predefined, or it may be configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0253] Optionally, the second or third transmission mode can correspond to a specific frequency domain resource. In this way, when the terminal receives the target physical downlink channel or schedules the DCI of the target physical downlink channel on the specific frequency domain resource, it can be assumed that the transmission mode adopted by the target physical downlink channel is the second or third transmission mode.

[0254] Optionally, the information in the MIB may include, for example, at least one of the following:

[0255] The subcarrier offset between the SSB and the common resource block grid in the MIB (i.e., k) SSB ), Spare bits.

[0256] Optionally, the values ​​of the information in the MIB can correspond to the transmission mode used by the target physical downlink channel. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of the correspondence.

[0257] For example, k SSB Take the first offset value corresponding to the first transmission mode, k SSB The second offset value corresponds to either the second or third transmission mode. For example, k SSB Take the first offset value corresponding to the first transmission mode, k SSB Take the second offset value corresponding to the second transmission mode, k SSB The third offset value corresponds to the third transmission mode. Thus, when the terminal receives the MIB, it can determine the k value from the MIB. SSB The value of determines the transmission mode used by the target physical downlink channel.

[0258] In some embodiments, the SSB-related information includes, but is not limited to, at least one of the following:

[0259] Synchronization raster used to receive the SSB;

[0260] The bandwidth of the SSB;

[0261] The synchronization sequence information in the SSB;

[0262] The PBCH demodulation reference signal (DMRS) in the SSB.

[0263] Optionally, the Sync raster used to receive the SSB corresponds to the transmission mode used by the target physical downlink channel. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0264] For example, the first Sync raster corresponds to the first transmission mode, and the second Sync raster corresponds to either the second or third transmission mode. Or, for another example, the first Sync raster corresponds to the first transmission mode, the second Sync raster corresponds to the second transmission mode, and the third Sync raster corresponds to the third transmission mode. In this way, the terminal can determine the transmission mode used by the target physical downlink channel based on the Sync raster where the received SSB is located.

[0265] Optionally, the bandwidth of the SSB corresponds to the transmission mode used by the target physical downlink channel. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0266] Therefore, the first network-side device can indicate the transmission mode used for the target physical downlink channel transmission to the terminal through the bandwidth of the SSB. Correspondingly, the terminal can determine the transmission mode used for the target physical downlink channel based on the bandwidth of the received SSB.

[0267] Optionally, the synchronization sequence information in the SSB corresponds to the transmission mode used by the target physical downlink channel. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0268] For example, the first synchronization sequence corresponds to the first transmission mode, and the second synchronization sequence corresponds to the second or third transmission mode. Or, for another example, the first synchronization sequence corresponds to the first transmission mode, the second synchronization sequence corresponds to the second transmission mode, and the third synchronization sequence corresponds to the third transmission mode. In this way, the terminal can determine the transmission mode used by the target physical downlink channel based on the synchronization sequence in the received SSB.

[0269] Optionally, the PBCH DMRS in the SSB corresponds to the transmission mode used by the target physical downlink channel. Optionally, this correspondence can be predefined, or configured by the first network-side device for the terminal, that is, the terminal and the first network-side device have the same understanding of this correspondence.

[0270] For example, the first PBCH DMRS corresponds to the first transmission mode, and the second PBCH DMRS corresponds to either the second or third transmission mode. Or, for another example, the first PBCH DMRS corresponds to the first transmission mode, the second PBCH DMRS corresponds to the second transmission mode, and the third PBCH DMRS corresponds to the third transmission mode. In this way, the terminal can determine the transmission mode used by the target physical downlink channel based on the PBCH DMRS received from the SSB.

[0271] In some embodiments, the information of the reference signal associated with the first information may include, but is not limited to, at least one of the following:

[0272] Reference signal indexes associated with the first information, such as the SSB index;

[0273] The index of the reference signal group associated with the first information, such as the SSB group index;

[0274] The format of the reference signal or reference channel associated with the first information, such as the SSB format.

[0275] In some embodiments, the broadcast information sent before the first information may include, but is not limited to:

[0276] Paging messages, Msg2, RAR, Msg4, MsgB.

[0277] For example, if the first message is Msg4, then the broadcast message sent before the first message can be RAR.

[0278] In other words, the transmission mode of Msg4 PDSCH can be indicated by RAR.

[0279] In some embodiments, the first network-side device can indicate the transmission mode of the target physical downlink channel via a DCI. Optionally, the DCI can be a DCI for scheduling the target physical downlink channel. That is, the first network-side device can indicate the transmission mode of the target physical downlink channel while scheduling it. For example, if the target physical downlink channel is a paging PDSCH, RAR PDSCH, Msg4 PDSCH, or MsgB PDSCH, the transmission mode of the target physical downlink channel can be indicated via a paging DCI.

[0280] In some embodiments, the first network-side device may indicate the transmission mode of the target physical downlink channel via RRC signaling. This RRC signaling is sent before the target physical downlink channel.

[0281] Optionally, the RRC signaling can be RRC release signaling.

[0282] For example, the first network-side device can configure the transmission mode of PDSCH in subsequent states (such as the RRC inactive state) in the RRC release signaling.

[0283] In some embodiments, the transmission mode of the target physical downlink channel can also be indicated by signaling (e.g., DCI, MAC signaling, or RRC signaling) from other network-side devices (e.g., network-side devices corresponding to other cells or other TRPs).

[0284] The following describes the indication method of resources used for target physical downlink channel transmission in conjunction with specific embodiments.

[0285] In some embodiments, the target physical downlink channel may be single DCI scheduled. For example, for the first transmission mode, the second transmission mode, and the third transmission mode, the target physical downlink channel may be single DCI scheduled.

[0286] In other embodiments, the target physical downlink channel may be scheduled by multiple DCIs. For example, for the third transmission mode, the target physical downlink channel may be scheduled by multiple DCIs.

[0287] The following describes, with reference to specific embodiments, the method of indicating resources when scheduling a target physical downlink channel through a single DCI.

[0288] Example 1: The target physical downlink channel is scheduled by the first DCI.

[0289] The first DCI may be a DCI used for scheduling the physical downlink channel in the first transmission mode, or a DCI used for scheduling single-PDSCH, or a DCI used for conventional PDSCH scheduling.

[0290] The first DCI uses an existing DCI format, such as DCI format 1-0.

[0291] In some embodiments, the target information field in the first DCI can be used to determine resource allocation information, or scheduling information, and transmission parameters for target physical downlink channel transmission.

[0292] Optionally, the target information field may include, but is not limited to, at least one of the following:

[0293] A first information field used to indicate time-domain resource allocation information, such as the TDRA field;

[0294] A second information field, such as the FDRA field, is used to indicate frequency domain resource allocation information;

[0295] A third information field used to indicate the MCS, such as the MCS field;

[0296] The fourth information field used to indicate RV, such as the RV field.

[0297] Example 1-1: The resource allocation information for target physical downlink channel transmission can be determined based on the target information field and the first table in the first DCI.

[0298] The first table includes resource allocation information for physical downlink channel transmission in the first transmission mode (or, resource allocation information for single-PDSCH transmission, and resource allocation information for conventional PDSCH) and resource allocation information for target physical downlink channel transmission in the target transmission mode, wherein the target transmission mode includes at least one of the second transmission mode and the third transmission mode.

[0299] In some implementations, the second table can be modified to obtain the first table. For example, columns or cells can be added to the second table, or multiple values ​​can be introduced into the cells to carry resource allocation information for the target physical downlink channel transmission in the target transmission mode. The second table only includes resource allocation information for physical downlink channel transmission in the first transmission mode (or, resource allocation information for single-PDSCH transmission, and resource allocation information for traditional PDSCH). It can be understood that the second table is an existing table for PDSCH resource allocation.

[0300] In some embodiments, the resource allocation information for physical downlink channel transmission in the target transmission mode in the first table may be independent resource allocation information, or it may be relative resource allocation information relative to the resource allocation information for physical downlink channel transmission in the first transmission mode. This application does not limit this further.

[0301] In some embodiments, the resource allocation information for target physical downlink channel transmission in the target transmission mode includes at least one of the following:

[0302] One or more time-domain intervals used for the target physical downlink channel transmission;

[0303] One or more frequency domain intervals used for the target physical downlink channel transmission;

[0304] A pattern of multiple time-domain units used for the target physical downlink channel transmission;

[0305] A pattern of multiple frequency domain units used for the target physical downlink channel transmission;

[0306] The position or pattern of other time domain units, excluding the first reference time domain unit, relative to the first reference time domain unit for the target physical downlink channel transmission;

[0307] The number of time-domain units used for the target physical downlink channel transmission;

[0308] The number of frequency domain units used for the target physical downlink channel transmission;

[0309] The maximum number of time-domain units used for the target physical downlink channel transmission;

[0310] The maximum number of frequency domain units used for the target physical downlink channel transmission;

[0311] A start symbol and multiple time-domain lengths are used for the transmission of the target physical downlink channel;

[0312] Multiple start symbols and a time-domain length are used for transmission of the target physical downlink channel;

[0313] Multiple start symbols and multiple time-domain lengths are used for the transmission of the target physical downlink channel;

[0314] The number of repeated transmissions of the target physical downlink channel.

[0315] It should be noted that the unit of time domain interval in the embodiments of this application can be a time slot, symbol, subframe, frame, millisecond, etc.

[0316] It should be noted that the unit of frequency domain spacing in the embodiments of this application can be PRB, subcarrier, etc.

[0317] In some embodiments, the first table may also indicate a starting time-domain unit, such as a start symbol, for the target physical downlink channel transmission. The one or more time-domain intervals for the target physical downlink channel transmission may be time-domain intervals corresponding to the starting time-domain unit. Therefore, the terminal can determine multiple time-domain units for the target physical downlink channel transmission based on the starting time-domain unit and the one or more time-domain intervals. Optionally, a new column may be added to the second table to indicate one or more time-domain intervals for the target physical downlink channel transmission.

[0318] For example, when the resource allocation information for target physical downlink channel transmission in target transmission mode includes a time-domain interval for target physical downlink channel transmission, the terminal can use a starting time-domain unit indicated by the first DCI as the first time-domain unit for target physical downlink channel transmission, and determine the second time-domain unit for target physical downlink channel transmission based on the starting time-domain unit and the time-domain interval.

[0319] For example, when the resource allocation information for target physical downlink channel transmission in target transmission mode includes multiple time-domain intervals for target physical downlink channel transmission, the terminal can use a starting time-domain unit indicated by the first DCI as the first time-domain unit for target physical downlink channel transmission, and determine multiple subsequent time-domain units other than the first time-domain unit for target physical downlink channel transmission based on the starting time-domain unit and the multiple time-domain intervals.

[0320] Optionally, the first table may indicate a starting frequency domain unit, such as a starting PRB, for the target physical downlink channel transmission. The one or more frequency domain intervals for the target physical downlink channel transmission may be frequency domain intervals corresponding to the starting frequency domain unit. Therefore, the terminal can determine multiple frequency domain units for the target physical downlink channel transmission based on the starting frequency domain unit and the one or more frequency domain intervals. Optionally, a new column may be added to the second table to indicate one or more frequency domain intervals for the target physical downlink channel transmission.

[0321] For example, when the resource allocation information for target physical downlink channel transmission in target transmission mode includes a frequency domain interval for target physical downlink channel transmission, the terminal can use a starting frequency domain unit indicated by the first DCI as the first frequency domain unit for target physical downlink channel transmission, and determine the second frequency domain unit for target physical downlink channel transmission based on the starting frequency domain unit and the frequency domain interval.

[0322] For example, when the resource allocation information for target physical downlink channel transmission in target transmission mode includes multiple frequency domain intervals for target physical downlink channel transmission, the terminal can use a starting frequency domain unit indicated by the first DCI as the first frequency domain unit for target physical downlink channel transmission, and determine multiple frequency domain units other than the first frequency domain unit for target physical downlink channel transmission based on the starting frequency domain unit and the multiple frequency domain intervals.

[0323] In some embodiments, the first table may also indicate multiple time-domain units (e.g., multiple time slots) for the target physical downlink channel transmission, such as indicating a pattern of multiple time-domain units for the target physical downlink channel transmission. The terminal can then determine the location of the multiple time-domain units for the target physical downlink channel transmission based on this pattern. Optionally, a new column may be added to the second table to indicate the pattern of the multiple time-domain units for the target physical downlink channel transmission.

[0324] In some embodiments, the first table may also indicate multiple frequency domain units for the target physical downlink channel transmission, for example, indicating a pattern of multiple frequency domain units for the target physical downlink channel transmission. The terminal can then determine the location of the multiple frequency domain units for the target physical downlink channel transmission based on the pattern. Optionally, a new column may be added to the second table to indicate the pattern of the multiple frequency domain units for the target physical downlink channel transmission.

[0325] In some embodiments, the first table may also indicate the position or pattern of other time-domain units (excluding the first reference time-domain unit) relative to the first reference time-domain unit for the target physical downlink channel transmission. Here, the position relative to the first reference time-domain unit may be the time-domain interval between the other time-domain units and the first reference time-domain unit. Optionally, a new column may be added to the second table to indicate the position or pattern of other time-domain units (excluding the first reference time-domain unit) relative to the first reference time-domain unit for the target physical downlink channel transmission.

[0326] Optionally, the first reference time-domain unit in the embodiments of this application may be the first time-domain unit used for target physical downlink channel transmission.

[0327] In one specific embodiment, the first table may further indicate the time-domain interval between the first time-domain unit and the second reference time-domain unit for the target physical downlink channel transmission, wherein the second reference time-domain unit is the time-domain unit where the first DCI is located. The terminal can then determine the position of the first time-domain unit for the target physical downlink channel transmission based on the second reference time-domain unit and the time-domain interval. Further, by combining the positions or patterns of other time-domain units (excluding the first reference time-domain unit) for the target physical downlink channel transmission relative to the first time-domain unit, multiple time-domain units for the target physical downlink channel transmission can be determined.

[0328] In some embodiments, the first table may be used to indicate the position or pattern of frequency domain units other than the first reference frequency domain unit for transmission of the target physical downlink channel relative to the first reference frequency domain unit. Here, the bit relative to the first reference frequency domain unit may be a frequency domain interval relative to the first reference frequency domain unit. Optionally, a new column may be added to the second table to indicate the position or pattern of frequency domain units other than the first reference frequency domain unit for transmission of the target physical downlink channel relative to the first reference frequency domain unit.

[0329] Optionally, the first reference frequency domain unit in the embodiments of this application may be the first frequency domain unit used for target physical downlink channel transmission.

[0330] In one specific embodiment, the first table may further indicate the frequency domain interval between the first frequency domain unit and the second reference frequency domain unit for the target physical downlink channel transmission, wherein the second reference frequency domain unit is the frequency domain unit where the first DCI is located. The terminal can then determine the position of the first frequency domain unit for the target physical downlink channel transmission based on the second reference frequency domain unit and the frequency domain interval. Further, by combining the positions or patterns of other frequency domain units (excluding the first reference frequency domain unit) for the target physical downlink channel transmission relative to the first frequency domain unit, multiple frequency domain units for the target physical downlink channel transmission can be determined.

[0331] In some embodiments, the first table may indicate the number of time-domain units used for the target physical downlink channel transmission. Furthermore, the first table may also indicate the time-domain interval between the first time-domain unit and the second reference time-domain unit for the target physical downlink channel transmission, where the second reference time-domain unit is the time-domain unit containing the first DCI. The terminal can then determine the location of the first time-domain unit used for the target physical downlink channel transmission based on the second reference time-domain unit and the time-domain interval. Thus, the terminal can determine multiple time-domain units used for the target physical downlink channel transmission based on the location of the first time-domain unit and the number of time-domain units.

[0332] Optionally, a new column can be added to the second table to indicate the number of time-domain units used for the target physical downlink channel transmission.

[0333] In some embodiments, the first table may indicate the number of frequency domain units used for the target physical downlink channel transmission. The first table may also indicate the frequency domain interval between a first frequency domain unit and a second reference frequency domain unit for the target physical downlink channel transmission, wherein the second reference frequency domain unit is the frequency domain unit where the first DCI is located. The terminal can then determine the location of the first frequency domain unit used for the target physical downlink channel transmission based on the second reference frequency domain unit and the frequency domain interval. Thus, the terminal can determine multiple frequency domain units used for the target physical downlink channel transmission based on the location of the first frequency domain unit and the number of frequency domain units.

[0334] Optionally, a new column can be added to the second table to indicate the number of frequency domain units used for the target physical downlink channel transmission.

[0335] Optionally, a new column can be added to the second table to indicate the maximum number of time-domain units used for the target physical downlink channel transmission.

[0336] Optionally, a new column can be added to the second table to indicate the maximum number of frequency domain units used for the target physical downlink channel transmission.

[0337] In some embodiments, the first table may indicate the number of frequency domain units used for target physical downlink channel transmission.

[0338] In some embodiments, the first table may indicate a starting symbol and multiple time-domain lengths (e.g., number of symbols) for transmission of the target physical downlink channel, in which case the starting symbol position of the target physical downlink channel is the same in each occupied time-domain unit, but the time-domain length within each time-domain unit is different.

[0339] In some embodiments, the first table may indicate a plurality of start symbols and a time-domain length (e.g., number of symbols) for transmission of the target physical downlink channel. In this case, the start symbol position of the target physical downlink channel may be different in each time-domain unit occupied, but the time-domain length in each time-domain unit is the same.

[0340] In some embodiments, the first table may indicate multiple start symbols and multiple time-domain lengths (e.g., the number of symbols) for transmission in the target physical downlink channel. Optionally, the multiple start symbols and the multiple time-domain lengths correspond one-to-one, that is, the Kth start symbol and the Kth time-domain length represent the time-domain resource allocation information on the Kth time-domain unit occupied by the target physical downlink channel.

[0341] Optionally, the multiple start symbols can be the same or different, and the multiple time domain lengths can be the same or different. That is, the start symbol position of the target physical downlink channel in each time domain cell may be different, and the time domain length in each time domain cell may also be different.

[0342] Optionally, in the above embodiments, the number of start symbols and / or time domain lengths can be used to indicate the number of time domain units occupied by the target physical downlink channel.

[0343] Optionally, multiple values ​​may be introduced in specific cells of the second table to indicate multiple start symbols and / or multiple time-domain lengths for transmission on the target physical downlink channel. For example, multiple values ​​may be introduced in a cell indicating a start symbol to indicate multiple start symbols. As another example, multiple values ​​may be introduced in a cell indicating a time-domain length to indicate multiple time-domain lengths.

[0344] It should be noted that the first network-side device can also indicate the starting PRB and frequency domain length in multiple frequency domain units for target physical downlink channel transmission in the manner described above, but for the sake of brevity, it will not be elaborated here.

[0345] In some embodiments, the first DCI can also be used to indicate the number of retransmissions of the target physical downlink channel.

[0346] For example, the target physical downlink channel includes a first physical downlink channel, and the first DCI can indicate the number of retransmissions of the first physical downlink channel.

[0347] For example, the target physical downlink channel includes multiple second physical downlink channels, and the first DCI can indicate the number of retransmissions of some or all of the second physical downlink channels.

[0348] Optionally, the number of repeated transmissions of the target physical downlink channel may not exceed a repeated transmission number threshold. Optionally, the repeated transmission number threshold may be the upper limit of the number of repeated transmissions of a single PDSCH.

[0349] Optionally, a new column can be added to the second table to indicate the number of retransmissions of the target physical downlink channel.

[0350] In some embodiments of this application, the resource allocation information for target physical downlink channel transmission in the first table for target transmission mode may be effective by default, or it may be effective through configuration or instruction.

[0351] For example, the resource allocation information for target physical downlink channel transmission in the target transmission mode in the first table (e.g., whether new columns, new cells, or new values ​​in cells, such as values ​​other than the first value among multiple values ​​in a cell, are effective (or whether they are used)) is determined according to at least one of the following:

[0352] Information in the MIB;

[0353] The value of the subcarrier offset between the SSB and the common resource block grid;

[0354] Specific CORESET;

[0355] Specific search space;

[0356] Specific PDCCH MO;

[0357] Specific RNTI;

[0358] Specific frequency domain resources;

[0359] DMRS or scrambled sequences of PBCH;

[0360] Loads in the PBCH, such as L1 loads;

[0361] Broadcast information sent before the first information;

[0362] The RRC signaling sent by the first network-side device;

[0363] The MAC signaling sent by the first network-side device;

[0364] The transmission mode of the target physical downlink channel is either the second transmission mode or the third transmission mode;

[0365] The resource allocation information is used in the same way as in the first table used for reference channel transmission.

[0366] In some embodiments, the resource allocation information for target physical downlink channel transmission in the first table for the target transmission mode can be indicated by information in the MIB. For example, it can be indicated by the spare bit in the MIB, where a specific value (e.g., 1) indicates that it is effective, and otherwise it is ineffective. Alternatively, it can be indicated by the presence of a specific bit in the MIB, where the presence of that specific bit indicates that it is effective, and otherwise it is ineffective.

[0367] In some embodiments, the subcarrier offset k between the SSB and the common resource block grid can be used. SSB The value of k indicates whether the resource allocation information for the target physical downlink channel transmission in the first table for the target transmission mode is effective. For example, k SSB It takes effect when a specific value is obtained; otherwise, it does not take effect.

[0368] In some embodiments, the resource allocation information for the target physical downlink channel transmission in the first table for the target transmission mode can be indicated by a specific CORESET, a specific search space, a specific PDCCH MO, or a specific frequency domain resource. For specific indication methods, please refer to the relevant description of indicating the transmission mode of the target physical downlink channel by a specific CORESET, a specific search space, a specific PDCCH MO, or a specific frequency domain resource. For the sake of brevity, it will not be repeated here.

[0369] In some embodiments, the DMRS sequence or scrambling sequence of the PBCH can indicate whether the resource allocation information for target physical downlink channel transmission in the first table for the target transmission mode is effective. For example, if the DMRS sequence or scrambling sequence of the PBCH is a specific DMRS sequence or scrambling sequence, it indicates that it is effective; otherwise, it indicates that it is ineffective.

[0370] In some embodiments, the L1 payload in the PBCH can be used to indicate whether the resource allocation information for target physical downlink channel transmission in the first table for the target transmission mode is effective. For example, if a specific bit in the L1 payload of the PBCH takes a specific value, it indicates that the information is effective; otherwise, it indicates that the information is ineffective.

[0371] In some embodiments, the broadcast information sent prior to the first information may include, but is not limited to, at least one of the following: Msg2, RAR, Msg4, paging message, system message, such as SIB1 or OSI. For example, a specific value for the broadcast information indicates that it is effective, otherwise it indicates that it is ineffective.

[0372] For example, the target information in the Msg2 PDSCH or RAR PDSCH can be used to indicate whether the resource allocation information for Msg4 PDSCH transmission uses the resource allocation information for target physical downlink channel transmission in the first table. Optionally, this target information can be information bits or information fields in the preceding common channel, or it can be a logical channel ID, or it can be uplink grant information in Msg2.

[0373] In some embodiments, the resource allocation information for target physical downlink channel transmission in the first table for the target transmission mode can be indicated by RRC or MAC signaling sent by the first network-side device. This RRC or MAC signaling may be sent before the target physical downlink channel.

[0374] In other words, the network-side device can use the RRC or MAC signaling sent earlier to indicate whether the resource allocation information for target physical downlink channel transmission in the first table for target transmission mode is effective. In this way, subsequent target physical downlink channel transmission using target transmission mode can determine whether to use the resource allocation information for target physical downlink channel transmission in the first table for target transmission mode based on the effectiveness information.

[0375] For example, the first network-side device can use an RRC release message to indicate whether the resource allocation information for target physical downlink channel transmission in the first table for target transmission mode is effective.

[0376] In some embodiments, when the first network-side device indicates that the transmission mode of the target physical downlink channel is the second transmission mode or the third transmission mode, the resource allocation information for the transmission of the target physical downlink channel in the first table is effective; or, when the first network-side device indicates that the transmission mode of the target physical downlink channel is the first transmission mode, the resource allocation information for the transmission of the target physical downlink channel in the first table is not effective.

[0377] In some embodiments, the resource allocation information in the first table for the target physical downlink channel is used in the same way as the resource allocation information in the first table for reference channel transmission.

[0378] Optionally, the reference channel can be a preceding transport channel of the target physical downlink channel, or a physical downlink channel transmitted before the target physical downlink channel.

[0379] For example, if the reference channel uses the second or third transmission mode and the reference channel uses the resource allocation information in the first table for transmission of the physical downlink channel in the second or third transmission mode, then the target physical downlink channel following the reference channel also uses the second or third transmission mode and uses the resource allocation information in the first table for transmission of the physical downlink channel in the second or third transmission mode.

[0380] For example, if the reference channel is SIB1 PDSCH, the second transmission mode is adopted, and the reference channel uses the resource allocation information in the first table for the second transmission mode or the physical downlink channel transmission of the second transmission mode, then the subsequent Msg2 PDSCH, Msg4 PDSCH or MsgB PDSCH also adopt the second transmission mode and use the resource allocation information in the first table for the second transmission mode or the physical downlink channel transmission of the second transmission mode.

[0381] Examples 1-2: Resource allocation information for target physical downlink channel transmission can be determined based on the target information field in the first DCI, the second table, and the first rule. The second table includes resource allocation information for physical downlink channel transmission in the first transmission mode, or it can be understood as an existing table for resource allocation in PDSCH.

[0382] In this embodiment 1-2, the second table can be left unchanged, and a first rule can be introduced instead. The first rule can be used to indicate the relationship between the resource allocation information for physical downlink channel transmission in the target transmission mode and the first transmission mode, or the method for determining the resource allocation information for physical downlink channel transmission in the target transmission mode. The terminal can determine the resource allocation information for physical downlink channel transmission in the target transmission mode based on the first DCI, the second table, and the first rule.

[0383] In some embodiments, the first rule includes, but is not limited to, at least one of the following:

[0384] The time-domain resource configurations in multiple time-domain units used for the target physical downlink channel transmission are the same as or have a specific time-domain interval as the time-domain resource configurations in the first reference time-domain unit.

[0385] The target physical downlink channel uses the same time-domain resource configuration within the multiple time-domain units it occupies;

[0386] The number of time-domain units used for the target physical downlink channel transmission is predefined or configured by the first network-side device, for example, through RRC signaling or MAC signaling;

[0387] The time-domain units used for the target physical downlink channel transmission are determined based on physical time-domain units, or based on available time-domain units;

[0388] The time domain units used for the target physical downlink channel transmission, other than the first time domain unit, are determined based on physical time domain units, or based on available time domain units;

[0389] The frequency domain resource configurations in multiple frequency domain units used for the target physical downlink channel transmission are the same as or have a specific frequency domain spacing as the frequency domain resource configurations in the first reference frequency domain unit.

[0390] The target physical downlink channel uses the same frequency domain resource configuration within the multiple frequency domain cells it occupies;

[0391] The number of frequency domain units used for the target physical downlink channel transmission is predefined or configured by the first network-side device.

[0392] In some embodiments, the time-domain resource configuration within the plurality of time-domain units used for the target physical downlink channel transmission is the same as the time-domain resource configuration within the first reference time-domain unit. Therefore, the terminal can determine the time-domain resource configuration within the plurality of time-domain units used for the target physical downlink channel transmission based on the time-domain resource configuration within the first reference time-domain unit.

[0393] Optionally, the first reference time-domain unit may be the first of a plurality of time-domain units used for transmission of the target physical downlink channel. Optionally, the time-domain resource configuration within the first reference time-domain unit may be determined according to the second table.

[0394] Optionally, the time-domain resource configuration may include, but is not limited to, the start symbol and / or the time-domain length.

[0395] That is, the starting symbol and / or time domain length in the multiple time domain units used for the transmission of the target physical downlink channel can be the same as the starting symbol and / or time domain length in the first reference time domain unit.

[0396] For example, the terminal can determine the starting symbol and time domain length in the first reference time domain unit based on the first information field and the second table of the first DCI. Furthermore, the starting symbol can be used as the starting symbol in multiple time domain units for transmission of the target physical downlink channel, and the time domain length can be used as the time domain length in multiple time domain units for transmission of the target physical downlink channel.

[0397] Optionally, the time-domain resource configurations within the multiple time-domain units used for the target physical downlink channel transmission and the time-domain resource configurations within the first reference time-domain unit have a specific time-domain interval. Therefore, the terminal can determine the time-domain resource configurations within the multiple time-domain units used for the target physical downlink channel transmission based on the time-domain resource configurations within the first reference time-domain unit and the specific time-domain interval.

[0398] Optionally, the time-domain resource configuration may include a start symbol and / or a time-domain length.

[0399] For example, the start symbol in the multiple time-domain units used for the target physical downlink channel transmission can have a specific time-domain interval with the start symbol in the first reference time-domain unit.

[0400] For example, the terminal can determine the start symbol in the first reference time domain based on the first information domain of the first DCI, and then determine the start symbol in multiple time domains for transmission of the target physical downlink channel based on the start symbol and the specific time domain interval.

[0401] In some embodiments, the target physical downlink channel uses the same time-domain resource configuration within the multiple time-domain units it occupies, which may include, but is not limited to:

[0402] The target physical downlink channel has the same starting symbol in multiple time-domain units, and / or,

[0403] The target physical downlink channel has the same time domain length in the multiple time domain units it occupies.

[0404] In some embodiments, the number of time-domain units used for transmission of the target physical downlink channel may be greater than or equal to 1. Optionally, the number of time-domain units used for transmission of the target physical downlink channel may be considered as the maximum number of time-domain units used for transmission of the target physical downlink channel, that is, the actual number of time-domain units used for transmission of the target physical downlink channel does not exceed this number.

[0405] Optionally, the frequency domain resource configuration within the multiple frequency domain units used for the target physical downlink channel transmission is the same as the frequency domain resource configuration within the first reference frequency domain unit. Therefore, the terminal can determine the frequency domain resource configuration within the multiple frequency domain units used for the target physical downlink channel transmission based on the frequency domain resource configuration within the first reference frequency domain unit.

[0406] Optionally, in this embodiment, the first reference frequency domain unit may be the first frequency domain unit among a plurality of frequency domain units used for the target physical downlink channel transmission. Optionally, the frequency domain resource configuration within the first reference frequency domain unit may be determined according to a second table.

[0407] For example, the terminal can determine the frequency domain resource configuration within the first reference frequency domain unit based on the second information field and the second table of the first DCI, and further, the frequency domain resource configuration can be used as the frequency domain resource configuration within multiple frequency domain units for the transmission of the target physical downlink channel.

[0408] Optionally, the frequency domain resource configurations within the multiple frequency domain units used for the target physical downlink channel transmission and the frequency domain resource configurations within the first reference frequency domain unit have a specific time domain interval. Therefore, the terminal can determine the frequency domain resource configurations within the multiple frequency domain units used for the target physical downlink channel transmission based on the frequency domain resource configurations within the first reference frequency domain unit and the specific frequency domain interval.

[0409] For example, the terminal can determine the frequency domain resource configuration within the first reference frequency domain unit based on the second information domain of the first DCI, and then determine the frequency domain resource configuration within multiple frequency domain units used for the transmission of the target physical downlink channel based on the frequency domain resource configuration and the specific frequency domain interval.

[0410] In some embodiments, the number of frequency domain units used for transmission of the target physical downlink channel may be greater than or equal to 1. Optionally, the number of frequency domain units used for transmission of the target physical downlink channel may be considered as the maximum number of frequency domain units used for transmission of the target physical downlink channel, that is, the actual number of frequency domain units used for transmission of the target physical downlink channel does not exceed this number.

[0411] In some embodiments, the time-domain units used for transmission on the target physical downlink channel are determined based on physical time-domain units. Optionally, the physical time-domain unit may be a time-domain unit configured by the first network-side device that can be used within the cell. For example, the physical time-domain unit is determined based on a continuous set of physical time-domain units available for downlink transmission. For instance, if the configured frame structure is DDDUU, then the continuous set of physical time slots available for downlink transmission is DDD, where D represents a downlink time slot and U represents an uplink time slot.

[0412] In some embodiments, the time-domain unit used for transmission on the target physical downlink channel is determined based on available time-domain units. For example, the available time-domain unit may be a physical time-domain unit that meets certain requirements; optionally, meeting these requirements may include, but is not limited to, not conflicting with other downlink channels. Alternatively, the available time-domain unit may be a time-domain unit configured by a first network-side device that is usable within the cell and meets certain requirements.

[0413] In some embodiments, the time-domain units other than the first time-domain unit used for transmission of the target physical downlink channel are determined based on physical time-domain units. For example, the time-domain resource configuration within the first time-domain unit can be determined according to a second table, such as based on the first information field and the second table of the first DCI, while the other time-domain units are determined based on physical time-domain units.

[0414] In some embodiments, the time-domain units other than the first time-domain unit used for the target physical downlink channel transmission are determined based on available time-domain units. For example, the time-domain resource configuration within the first time-domain unit can be determined according to a second table, such as based on the first information field and the second table of the first DCI, and the other time-domain units are determined based on available time-domain units.

[0415] In some embodiments of this application, the method 200 further includes:

[0416] If there is a conflict between the time domain unit (which may be any time domain unit used for the target physical downlink channel transmission, or any time domain unit other than the first time domain unit) determined according to the physical time domain unit and the time domain unit used for the third physical downlink channel transmission, the first network-side device performs a first operation, the first operation including at least one of the following:

[0417] Discard the physical downlink channel transmissions in all time-domain units where the target physical downlink channel is located;

[0418] Prioritize the transmission of the target physical downlink channel and discard the third physical downlink channel;

[0419] According to the second rule, determine whether to discard (or transmit) the target physical downlink channel transmission, or determine whether to transmit the target physical downlink channel or the third physical downlink channel.

[0420] In some embodiments, the conflict between the time-domain unit used for the target physical downlink channel transmission and the time-domain unit used for the third physical downlink channel transmission may include, but is not limited to, at least one of the following:

[0421] The overlap ratio between the time-domain units used for the target physical downlink channel transmission and the time-domain units used for the third physical downlink channel transmission is greater than a specific threshold, such as 80% or 75%.

[0422] The time-domain interval between the time-domain unit used for the target physical downlink channel transmission and the time-domain unit used for the third physical downlink channel transmission is less than a specific time-domain interval threshold.

[0423] Optionally, this specific ratio threshold can be predefined, or determined by the first network-side device.

[0424] Optionally, the specific time-domain interval threshold can be predefined, or determined by the first network-side device.

[0425] It should be noted that if the first network-side device discards the target physical downlink channel transmission on a time-domain unit, it can be assumed that the time-domain unit used for the target physical downlink channel transmission does not include that time-domain unit.

[0426] In some embodiments, if there is a conflict between the time domain unit determined according to the physical time domain unit for transmission of the target physical downlink channel and the time domain unit for transmission of the third physical downlink channel, the first network-side device discards physical downlink channel transmissions on all time domain units where the target physical downlink channel is located, including at least one of the following:

[0427] When the first information carried in the target physical downlink channel is SIB1, and the third physical downlink channel is used to transmit SSB, the first network-side device can discard the transmission of physical downlink channels in all time-domain units where the target physical downlink channel is located.

[0428] When the first information carried in the target physical downlink channel is RAR or Msg2, and the third physical downlink channel is one or more of SSB, SIB1PDCCH / PDSCH, PRACH, MsgA PRACH / PUSCH, the first network-side device may discard the physical downlink channel transmission on all time-domain units where the target physical downlink channel is located.

[0429] When the first information carried in the target physical downlink channel is contention resolution related information, namely Msg4 or MsgB, and the third physical downlink channel is one or more of SSB, SIB1 PDCCH / PDSCH, PRACH, MsgA PRACH / PUSCH, Msg2 PDCCH / PDSCH, Msg3, and PDCCH scheduling Msg3 retransmission, the first network-side device may discard the physical downlink channel transmission on all time-domain units where the target physical downlink channel is located.

[0430] When the first information carried in the target physical downlink channel is Paging related information, and the third physical downlink channel is one or more of SSB, SIB1PDCCH / PDSCH, PRACH, MsgA PRACH / PUSCH, Msg2 PDCCH / PDSCH, and Msg3, the first network-side device can discard the physical downlink channel transmission on all time-domain units where the target physical downlink channel is located.

[0431] When the first information carried in the target physical downlink channel is Small Data Transmission (SDT) related information, and the third physical downlink channel is one or more of SSB, SIB1 PDCCH / PDSCH, PRACH, MsgA PRACH / PUSCH, Msg2 PDCCH / PDSCH, Msg3, Msg4 PDCCH / PDSCH, and MsgB PDCCH / PDSCH, the first network-side device may discard the physical downlink channel transmissions on all time-domain units where the target physical downlink channel is located.

[0432] In some embodiments, if there is a conflict between the time domain unit determined according to the physical time domain unit for transmission of the target physical downlink channel and the time domain unit for transmission of the third physical downlink channel, the first network-side device prioritizes transmission of the target physical downlink channel, and discards the third physical downlink channel, including at least one of the following:

[0433] When the first information carried in the target physical downlink channel is SIB1, and the third physical downlink channel is one or more of the following: other PDCCH besides SIB1 PDCCH, other PDSCH besides SIB1 PDSCH, PRACH, and common PUSCH, the first network-side device prioritizes transmitting the target physical downlink channel and discards the third physical downlink channel.

[0434] When the first information carried in the target physical downlink channel is RAR-related information, contention resolution-related information, or Paging-related information, and the third physical downlink channel is one or more of the following: other PDCCHs besides SIB1 PDCCH, other PDSCHs besides SIB1 PDSCH, public PUSCH, and dedicated PUCCH, the first network-side device prioritizes transmitting the target physical downlink channel and discards the third physical downlink channel.

[0435] In some embodiments of this application, the second rule includes, but is not limited to, at least one of the following:

[0436] Whether to discard the target physical downlink channel transmission depends on whether the time domain unit in which the conflict occurs is the first time domain unit used for the target physical downlink channel transmission.

[0437] The physical downlink channels to be discarded are determined based on the priorities of the target physical downlink channel and the third physical downlink channel.

[0438] If the target physical downlink channel and the third physical downlink channel have the same priority, the physical downlink channel with the earlier start time shall be transmitted first.

[0439] Based on the transmission mode of the target physical downlink channel, determine the physical downlink channel to be discarded;

[0440] The physical downlink channels to be discarded are determined based on the type of information carried in the target physical downlink channel.

[0441] In some embodiments, determining whether to discard the target physical downlink channel transmission based on whether the conflicting time-domain unit is the first time-domain unit used for the target physical downlink channel transmission may include:

[0442] If the time-domain unit involved in the conflict is the first time-domain unit used for transmission of the target physical downlink channel, then the target physical downlink channel is not discarded, and the third physical downlink channel is discarded; or...

[0443] If the time-domain unit involved in the conflict is not the first time-domain unit used for the transmission of the target physical downlink channel, the target physical downlink channel is discarded and a third physical downlink channel is transmitted.

[0444] In some embodiments, determining the discarded physical downlink channel based on the priority of the target physical downlink channel and the third physical downlink channel includes:

[0445] If the priority of the target physical downlink channel is higher than that of the third physical downlink channel, the third physical downlink channel is discarded and the target physical downlink channel is transmitted; or

[0446] If the priority of the target physical downlink channel is lower than that of the third physical downlink channel, the third physical downlink channel is determined to be transmitted, and the target physical downlink channel is discarded.

[0447] Optionally, in some embodiments, the priority ordering of the physical downlink channels can be:

[0448] The priority of the SSB is greater than the priority of the PDCCH, which is greater than the transmission priority of the first time-domain unit of the target physical downlink channel, which is greater than the transmission priority of other time-domain units of the target physical downlink channel, which is greater than the priority of other PDSCHs.

[0449] In some embodiments, determining the discarded physical downlink channel based on the transmission mode of the target physical downlink channel includes:

[0450] If the transmission mode of the target physical downlink channel is the second transmission mode, and a conflict occurs between the first time-domain unit used for transmission of the target physical downlink channel and the time-domain unit used for transmission of the third physical downlink channel, then the third physical downlink channel is discarded; or

[0451] If the transmission mode of the target physical downlink channel is the second transmission mode, and a conflict occurs between the target physical downlink channel transmission and the time domain unit used for the third physical downlink channel transmission in subsequent time domain units other than the first time domain unit, then the target physical downlink channel transmission in the other time domain units is discarded; or

[0452] If the transmission mode of the target physical downlink channel is the third transmission mode, and a conflict occurs between the time domain unit used for the transmission of the target physical downlink channel and the time domain unit used for the transmission of the third physical downlink channel, then the transmission of the target physical downlink channel in the conflicting time domain unit is discarded.

[0453] In some embodiments, determining the discarded physical downlink channel based on the type of information carried in the target physical downlink channel includes:

[0454] If the first information carried in the target physical downlink channel is SIB1, then the transmission of the third physical downlink channel on the time-domain unit where the collision occurred is discarded.

[0455] In some embodiments, the time-domain unit determined based on available resource units for transmission of the target physical downlink channel satisfies at least one of the following:

[0456] The time-domain unit used for the target physical downlink channel transmission does not overlap with the time-domain unit where the SSB is located;

[0457] The time-domain unit used for the target physical downlink channel transmission does not overlap with the time-domain unit where PRACH is located;

[0458] The time-domain unit used for the target physical downlink channel transmission does not overlap with the time-domain unit where the PUSCH carrying MsgA is located.

[0459] The time-domain unit used for the target physical downlink channel transmission does not overlap with the time-domain unit where the common PDCCH is located. For example, the time-domain unit used for the target physical downlink channel transmission does not overlap with SS0 or CORESET0.

[0460] The time-domain unit used for the transmission of the target physical downlink channel is a downlink time-domain unit (e.g., a downlink slot or a downlink symbol) or a flexible time-domain unit (e.g., a flexible slot or a flexible symbol). Optionally, the downlink symbol can be determined according to TDD-UL-DL-ConfigCommon.

[0461] The time-domain resources used for target physical downlink channel transmission are downlink resources, such as time-domain resources on DLband resources in FDD, or time-domain resources on downlink subbands in subband full-duplex mode.

[0462] Examples 1-3: The resource allocation information for the target physical downlink channel transmission is determined based on the target information field and the third table in the first DCI.

[0463] The third table includes resource allocation information for target physical downlink channel transmission under the target transmission mode. For example, the third table may include resource allocation information for target physical downlink channel transmission under the second transmission mode, or it may include resource allocation information for target physical downlink channel transmission under the third transmission mode.

[0464] Optionally, the second transmission mode and the third transmission mode can each correspond to a third table, or a third table can be used to carry resource allocation information for the target physical downlink channel transmission under these two transmission modes.

[0465] That is, in embodiments 1-3, a resource allocation table for target physical downlink channel transmission in the second or third transmission mode can be introduced. In this way, the terminal can determine the resource allocation information for the target physical downlink channel transmission based on the target information field in the first DCI and the third table.

[0466] In some embodiments of this application, the third table is used to indicate at least one of the following:

[0467] The time-domain interval between the first time-domain unit and the second reference time-domain unit used for the transmission of the target physical downlink channel, wherein the second reference time-domain unit is the time-domain unit in which the first DCI is located;

[0468] The frequency domain spacing between the first frequency domain unit and the second reference frequency domain unit used for the target physical downlink channel transmission, wherein the second reference frequency domain unit is the frequency domain unit in which the first DCI is located;

[0469] The time-domain interval between different physical downlink channels in the target physical downlink channel;

[0479] The number of continuous frequency domain units used for the target physical downlink channel transmission;

[0480] The start symbol on each of the multiple time-domain units used for the target physical downlink channel transmission;

[0481] The time domain length of each of the multiple time domain units used for the target physical downlink channel transmission;

[0482] The starting frequency in each of the multiple frequency domain units used for the target physical downlink channel transmission;

[0483] Frequency domain length of each of the multiple frequency domain units used for the target physical downlink channel transmission.

[0484] In some embodiments, the third table may indicate the time-domain interval between the first time-domain unit and the second reference time-domain unit used for the target physical downlink channel transmission. The terminal can then determine the location of the first time-domain unit used for the target physical downlink channel transmission based on the second reference time-domain unit and the time-domain interval.

[0485] For example, if the unit of the time-domain interval between the first time-domain unit and the second reference time-domain unit used for the transmission of the target physical downlink channel is a symbol, and assuming that the time-domain interval is N symbols, it means that the terminal starts receiving the target physical downlink channel from the (N+1)th symbol after receiving the symbol containing the first DCI. Optionally, if N is 0, it means that the target physical downlink channel is received from the symbol following the symbol containing the first DCI.

[0486] For example, the unit of the time domain interval between the first time domain unit and the second reference time domain unit used for the transmission of the target physical downlink channel is a time slot. Assuming that the time domain interval is N time slots, it means that the terminal starts receiving the target physical downlink channel from the (N+1)th time slot after receiving the time slot where the first DCI is located. Optionally, if N is 0, it means that the target physical downlink channel is received from the next time slot after receiving the time slot where the first DCI is located.

[0487] In some embodiments, the third table may indicate the frequency domain spacing between the first frequency domain unit and the second reference frequency domain unit used for the target physical downlink channel transmission. The terminal can then determine the location of the first frequency domain unit used for the target physical downlink channel transmission based on the second reference frequency domain unit and the frequency domain spacing.

[0488] In some embodiments, when the target physical downlink channel includes a plurality of second physical downlink channels, the time-domain interval between different physical downlink channels in the target physical downlink channel may be the time-domain interval between the plurality of second physical downlink channels.

[0489] In some embodiments, when the target physical downlink channel includes a plurality of second physical downlink channels, the frequency domain spacing between different physical downlink channels in the target physical downlink channel may be the frequency domain spacing between the plurality of second physical downlink channels.

[0490] In some embodiments, the third table may indicate a pattern of multiple time-domain units used for the target physical downlink channel transmission, and the terminal can determine all time-domain units used for the target physical downlink channel transmission based on the pattern. Optionally, if the pattern is 1245 and the time-domain unit is a time slot, it indicates that the 1st, 2nd, 4th, and 5th time slots are time slots used for the target physical downlink channel transmission.

[0491] In some embodiments, the third table may indicate a pattern of multiple frequency domain units used for the target physical downlink channel transmission, and the terminal may determine all frequency domain units used for the target physical downlink channel transmission based on the pattern.

[0492] In some embodiments, the third table may indicate the positions or patterns of other time-domain units (excluding the first time-domain unit) relative to the first time-domain unit used for the target physical downlink channel transmission. The third table may also indicate the time-domain interval between the first time-domain unit and the second reference time-domain unit used for the target physical downlink channel transmission. Then, the terminal can determine the position of the first time-domain unit used for the target physical downlink channel transmission based on the second reference time-domain unit and the time-domain interval, and further, by combining the positions of other time-domain units relative to the first time-domain unit, determine all time-domain units used for the target physical downlink channel transmission.

[0493] In some embodiments, the third table may indicate the positions or patterns of other frequency domain units (excluding the first frequency domain unit) relative to the first frequency domain unit used for the target physical downlink channel transmission. The third table may also indicate the frequency domain spacing between the first frequency domain unit and the second reference frequency domain unit used for the target physical downlink channel transmission. Then, the terminal can determine the position of the first frequency domain unit used for the target physical downlink channel transmission based on the second reference frequency domain unit and the frequency domain spacing, and further, by combining the positions of other frequency domain units relative to the first frequency domain unit, determine all frequency domain units used for the target physical downlink channel transmission.

[0494] In some embodiments, the third table may indicate the number of time-domain units used for the target physical downlink channel transmission, and the third table may also indicate the time-domain interval between the first time-domain unit and the second reference time-domain unit used for the target physical downlink channel transmission. The terminal can then determine the position of the first time-domain unit used for the target physical downlink channel transmission based on the second reference time-domain unit and the time-domain interval, and further determine all time-domain units used for the target physical downlink transmission based on the position of the first time-domain unit used for the target physical downlink channel transmission and the number of such time-domain units.

[0495] In some embodiments, the third table may indicate the number of frequency domain units used for the target physical downlink channel transmission, and the third table may also indicate the frequency domain spacing between the first frequency domain unit and the second reference frequency domain unit used for the target physical downlink channel transmission. The terminal can then determine the position of the first frequency domain unit used for the target physical downlink channel transmission based on the second reference frequency domain unit and the frequency domain spacing, and further determine all frequency domain units used for the target physical downlink transmission based on the position of the first frequency domain unit used for the target physical downlink channel transmission and the number of such frequency domain units.

[0496] In some embodiments, the third table may indicate the number of consecutive time-domain units used for the target physical downlink channel transmission, and the third table may also indicate the time-domain interval between the first time-domain unit and the second reference time-domain unit used for the target physical downlink channel transmission. The terminal can then determine the position of the first time-domain unit used for the target physical downlink channel transmission based on the second reference time-domain unit and the time-domain interval, and further determine all time-domain units used for the target physical downlink transmission based on the position of the first time-domain unit used for the target physical downlink channel transmission and the number of consecutive time-domain units.

[0497] In some embodiments, the third table may indicate the number of consecutive frequency domain units used for the target physical downlink channel transmission, and the third table may also indicate the frequency domain spacing between the first frequency domain unit and the second reference frequency domain unit used for the target physical downlink channel transmission. The terminal can then determine the position of the first frequency domain unit used for the target physical downlink channel transmission based on the second reference frequency domain unit and the frequency domain spacing, and further determine all frequency domain units used for the target physical downlink transmission based on the position of the first frequency domain unit used for the target physical downlink channel transmission and the number of consecutive frequency domain units.

[0498] In some embodiments, the third table may indicate the start symbol and / or time length of each of the plurality of time-domain units used for transmission of the target physical downlink channel. For example, the terminal may determine the start symbol and / or time length of each of the plurality of time-domain units used for transmission of the target physical downlink channel based on the first information field in the first DCI and the third table.

[0499] Optionally, in some embodiments, the time-domain resources on each of the multiple time-domain units used for target physical downlink channel transmission are configured identically, so that the third table may only indicate a set of start symbols and time-domain lengths, applicable to all time-domain units.

[0500] In some embodiments, the third table may also indicate the starting frequency and / or frequency length of each of the plurality of time-domain units used for transmission of the target physical downlink channel. For example, the terminal may determine the starting frequency and / or frequency length of each of the plurality of frequency-domain units used for transmission of the target physical downlink channel based on the second information field in the first DCI and the third table.

[0501] Optionally, in some embodiments, the frequency domain resources on each of the multiple frequency domain units used for target physical downlink channel transmission are configured identically, so that the third table may only indicate a set of starting frequencies and frequency domain lengths applicable to all frequency domain units.

[0502] In some embodiments, the first DCI is used to indicate a frequency domain resource configuration, wherein all physical downlink channels included in the target physical downlink channel use the frequency domain resource configuration on their corresponding time domain units, that is, the system's frequency domain resource configuration, such as FDRA configuration, is used on all time domain units.

[0503] In other embodiments, the first DCI is used to indicate multiple frequency domain resource configurations, each frequency domain resource configuration being applied to a time domain unit of the target physical downlink channel transmission, and the target physical downlink channel using the corresponding frequency domain resource configuration on the corresponding time domain unit. That is, all time domain units of the target physical downlink channel use independent frequency domain resource configurations, and the first DCI can indicate the corresponding frequency domain resource configuration on each time domain unit separately.

[0504] In some other embodiments, the first DCI is used to indicate a reference frequency domain resource configuration and at least one relative frequency domain resource configuration, wherein the reference frequency domain resource configuration is applied to a first reference time domain unit (e.g., the first time domain unit) among a plurality of time domain units for transmission of the target physical downlink channel, or corresponds to a reference physical downlink channel (e.g., the lowest frequency reference downlink channel) in the target physical downlink channel; the at least one relative frequency domain resource configuration is applied to at least one time domain unit other than the first reference time domain unit among a plurality of time domain units for transmission of the target physical downlink channel, or the at least one relative frequency domain resource configuration corresponds to other physical downlink channels in the target physical downlink channel other than the reference physical downlink channel.

[0505] In some embodiments, the MCS used by all physical downlink channels included in the target physical downlink channel transmission may be the same, or they may be different.

[0506] For example, an MCS can be indicated by the third information field (e.g., the MCS field) in the first DCI, applicable to all physical downlink channels included in the target physical downlink channel transmission. Alternatively, multiple MCSs can be indicated for multiple second physical downlink channels included in the target physical downlink channel transmission, wherein the multiple MCSs and the multiple second physical downlink channels correspond one-to-one.

[0507] In some embodiments, the RV used by all physical downlink channels included in the target physical downlink channel transmission may be the same, or they may be different.

[0508] For example, an RV can be indicated by the fourth information field (e.g., the RV field) in the first DCI, applicable to all physical downlink channels included in the target physical downlink channel transmission. Alternatively, multiple RVs can be indicated for multiple second physical downlink channels included in the target physical downlink channel transmission, wherein the multiple RVs correspond one-to-one with the multiple second physical downlink channels.

[0509] In some embodiments, the third form is enabled by default, or it may be enabled by configuration or instruction.

[0510] In some embodiments, the effectiveness of the third form is determined based on at least one of the following:

[0524] The resource allocation information is used in the same way as in the third table used for reference channel transmission.

[0525] The specific implementation of whether the third table is effective refers to the relevant description of the effectiveness method of the resource allocation information for target physical downlink channel transmission in the first table, which will not be repeated here for the sake of brevity.

[0526] Example 2: The target physical downlink channel is scheduled by the second DCI.

[0527] The second DCI can be a DCI used for scheduling physical downlink channels in a second transmission mode and / or a third transmission mode. That is, in the embodiments of this application, a DCI format for scheduling physical downlink channels in a second transmission mode and / or a third transmission mode can be introduced.

[0528] In some embodiments, the second DCI is used to indicate resource allocation information for target physical downlink channel transmission in the target transmission mode, wherein the target transmission mode includes at least one of a second transmission mode and a third transmission mode.

[0529] It should be noted that, in the embodiments of this application, the DCI used to schedule the physical downlink channel transmission in the second transmission mode and the third transmission mode may correspond to the same DCI format, or they may correspond to different DCI formats respectively. This application does not limit this.

[0543] Optionally, the TB scaling factor can be used to determine the TB size (TBS) corresponding to the target physical downlink channel.

[0559] Optionally, the terminal may determine the position of the first frequency domain unit for the target physical downlink channel transmission based on the information field indicating the first frequency domain unit for the target physical downlink channel transmission, further determine the number of frequency domain units for the target physical downlink channel transmission based on the information field indicating the number of frequency domain units for the target physical downlink channel transmission, and then determine multiple frequency domain units for the target physical downlink channel transmission based on the position of the first frequency domain unit in combination with the number of frequency domain units.

[0560] Optionally, the terminal may determine the position of the first time-domain unit for the target physical downlink channel transmission based on the information field indicating the first time-domain unit for the target physical downlink channel transmission, further determine the number of consecutive time-domain units for the target physical downlink channel transmission based on the information field indicating the number of consecutive time-domain units for the target physical downlink channel transmission, and then determine multiple time-domain units for the target physical downlink channel transmission based on the position of the first time-domain unit in combination with the number of consecutive time-domain units.

[0562] In some embodiments, where the target transmission mode is a second transmission mode and the target physical downlink channel is transmitted through multiple spatial resources, the second DCI further includes at least one of the following fields:

[0563] An information field indicating the antenna configuration of each of the multiple spatial resources used for the target physical downlink channel transmission;

[0564] An information field indicating the port configuration of each of the multiple spatial resources used for the target physical downlink channel transmission;

[0565] The information field indicating the configuration of the Precoding Matrix Indicator (PMI) for each of the multiple spatial resources used for transmission of the target physical downlink channel;

[0566] An information field indicating the layer configuration of each of the multiple spatial resources used for transmission of the target physical downlink channel.

[0567] In some embodiments, when the first information is specific information, or the target physical downlink channel is a specific PDSCH, at least some of the transmission parameters for the target physical downlink channel may be indicated using non-DCI signaling, for example, the non-DCI signaling includes at least one of the following:

[0568] L1 load in MIB and PBCH, RAR, MsgB, Msg4, Paging messages, system messages (such as SIB1 or OSI), RRC signaling, and MAC layer signaling.

[0569] Optionally, this specific information may include, but is not limited to, RAR, Msg2, MsgB, Msg4, paging messages, etc.

[0574] Optionally, the number of time-domain units indicated by the DCI used to schedule the transmission of the target physical downlink channel can exceed the maximum number of symbols within a time slot, or it can indicate symbols across time slots.

[0575] For example, as shown in Figure 3, the number of symbols (i.e., 15) scheduled by the first network-side device for transmission of the target physical downlink channel can exceed the maximum number of symbols in a time slot (i.e., 14). In other words, the first network-side device can indicate symbols across time slots, that is, the symbols scheduled for transmission of the target physical downlink channel span time slot #1 and time slot #2.

[0576] In some embodiments of this application, the method 200 further includes:

[0577] The terminal determines the target TBS corresponding to the target physical downlink channel.

[0578] For example, the TBS corresponding to the target physical downlink channel in the first transmission mode can be calculated using the existing TBS determination method. For the TBS corresponding to the target physical downlink channel in the third transmission mode, the existing TBS determination method can be sampled to calculate the TBS corresponding to each second physical downlink channel in the target physical downlink channel, and then the TBS corresponding to all second physical downlink channels can be summed to obtain the TBS corresponding to the target physical downlink channel.

[0579] The following explains how the TBS corresponding to the target physical downlink channel in the second transmission mode is determined.

[0580] Method 1:

[0583] The terminal performs quantization processing on the number of intermediate information bits in each time domain unit to determine the transport block size (TBS) in each time domain unit.

[0584] The terminal adds up the TBS of all time-domain units where the target physical downlink channel is located to obtain the target TBS corresponding to the target physical downlink channel.

[0585] In some embodiments, the number of available REs for the target physical downlink channel in each time domain unit can be determined by the following steps:
