Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a method and apparatus for determining time-domain resources. Background Technology

[0002] High frequencies (above 6 GHz, mainly including 28 GHz, 39 GHz, 60 GHz, 73 GHz, etc.) have become a hot topic of research and development in the industry due to their abundant spectrum resources, used to address the ever-increasing communication demands. In particular, the 52.6–71 GHz spectrum is characterized by its large bandwidth. To fully utilize this spectrum resource and improve peak rates or throughput, the industry has proposed increasing the bandwidth occupied by a single component carrier (CC) from the current 400 MHz in New Radio (NR) communication systems to approximately 2 GHz or higher. Simultaneously, due to limitations in terminal hardware and increasingly stringent requirements for data demodulation latency, the maximum number of Fast Fourier Transform (FFT) points (higher FFT points result in higher complexity) and the maximum number of resource blocks are limited. Considering all these factors, research has been proposed on larger subcarrier spacings such as 240 kHz, 480 kHz, 960 kHz, and even 1920 kHz.

[0003] In existing NR systems, the scheduling of shared channels, the detection period of control channels, and the hybrid automatic repeat request (HARQ) process are all related to the subcarrier spacing. For example, the scheduling unit of the shared channel is a time slot (14 Orthogonal Frequency Division Multiplexing (OFDM) symbols) or a mini-time slot (2-13 OFDM symbols). The duration of the time slot is determined by the subcarrier spacing; the larger the subcarrier spacing, the shorter the duration of the time slot. Figure 1 As shown in the diagram, one rectangle represents a time slot. It can be seen that a time slot with a subcarrier frequency of 120kHz can contain two time slots with a subcarrier frequency of 240kHz, four time slots with a subcarrier frequency of 480kHz, and eight time slots with a subcarrier frequency of 960kHz. The detection frequency of the control channel is also a time slot. Therefore, when the data subcarrier spacing increases from 120kHz in the existing NR system to 480kHz or 960kHz, the time slot time corresponding to 480kHz or 960kHz will be shortened to 1 / 4 or 1 / 8 of the time slot time of 120kHz. If the control channel is still detected in units of time slots at this time, it will pose a significant challenge to the processing capacity of the terminal.

[0004] For the problem of slot shortening in large subcarrier spacing, one of the solutions is multi-slot scheduling, in which one downlink control information (DCI) can schedule multiple physical downlink shared channels (PDSCHs) or multiple physical uplink shared channels (PUSCHs). Since the multiple PDSCHs or multiple PUSCHs scheduled by the DCI span multiple slots, the slots may contain resources of some other channels or other reference signals, which cannot be used for transmitting the PDSCHs or PUSCHs. Therefore, it is further proposed that the time domain resources of the multiple PDSCHs or multiple PUSCHs scheduled by a single DCI can be discontinuous, mainly referring to slot-level discontinuity. On this basis, it is further necessary to determine how to indicate the time domain resources of the multiple discontinuous PDSCHs or PUSCHs. SUMMARY

[0105] Figure 3 is a schematic diagram of an example of a method for determining a time domain resource according to the embodiments of the present application. As Figure 3 indicated, the method 300 includes:

[0106] It should be understood that the time domain resources of the shared channel in the embodiments of the present application can correspond to the time domain resources of the uplink shared channel of the uplink transmission, or can correspond to the time domain resources of the downlink shared channel of the downlink transmission. The method for determining the time domain resources of the shared channel in the embodiments of the present application is described below by taking the downlink transmission as an example.

[0107] S310, the network device sends time domain resource configuration information to the terminal device, the time domain resource configuration information being used for configuring SLIV and a bit map.

[0108] Optionally, the time domain resource configuration information can be carried in radio resource control (RRC) signaling.

[0109] Specifically, the time domain resource configuration information can include a time domain resource allocation table (TDRA), and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N start and length indicator values (SLIVs). Each SLIV is used to indicate the time domain resources of a shared channel in a time slot. Specifically, each SLIV indicates the time domain resources of the shared channel corresponding to the SLIV in which symbols in a time slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the shared channels corresponding to the N SLIVs in the time slot.

[0110] In some embodiments, the first information in the first table entry is associated with a second information, and the second information includes a bit map. Each bit in the bit map corresponds to a time slot, and the value of each bit in the bit map indicates whether there is a shared channel in the time slot corresponding to the bit.

[0111] Optionally, the second information associated with the first information can be included in the first table entry together with the first information, in other words, the first table entry includes the first information and the second information.

[0112] In some embodiments, the first information included in the plurality of first entries all associates the same second information. The second information includes a bitmap, each bit of the bitmap corresponds to a time slot, and a value of each bit of the bitmap indicates whether there is a time domain resource of a shared channel indicated by one of the N SLIVs on a time slot corresponding to the bit.

[0113] Optionally, the same second information associated by the first information included in the plurality of first entries in the TDRA table can not be included in the first information in each first entry, in other words, the same second information associated by the plurality of first information in the plurality of entries can be configured separately for the TDRA table, or predefined.

[0114] Optionally, all the first information included in the plurality of first entries in the TDRA table associates the same second information. The second information can be predefined, or the second information is configured separately outside the TDRA table.

[0115] In some embodiments, the first information included in the one first entry associates a set of bitmaps, the set of bitmaps includes a plurality of bitmaps, each bitmap corresponds to a second information, each bit of a bitmap corresponds to a time slot, and a value of each bit of a bitmap corresponding to a second information indicates whether there is a time domain resource of a shared channel indicated by one of the N SLIVs on a time slot corresponding to the bit.

[0116] Optionally, the set of bitmaps can be predefined by a protocol.

[0117] Optionally, the time domain resource configuration information includes configuration information of the set of bitmaps.

[0118] Optionally, a bitmap in the set of bitmaps can be indicated by the time domain resource indication information, for example, can be indicated by DCI signaling.

[0119] In the above embodiments, a value of 1 of a bit can represent that there is a time domain resource of a shared channel indicated by one of the N SLIVs on a time slot corresponding to the bit, and a value of 0 of a bit can represent that there is no time domain resource of a shared channel on a time slot corresponding to the bit. As an example but not limitation, bits in a bitmap are distributed in order, and a distribution order of bits with a value of 1 in the bitmap corresponds to an arrangement order of the N SLIVs included in the first information, for example, a time domain resource of a shared channel corresponding to a second SLIV of the N SLIVs is located on a time slot corresponding to a second bit with a value of 1 in the bitmap.

[0120] It should be noted that the value of the bit position being 0 can also be used to indicate that the time domain resource of the shared channel indicated by one of the N SLIVs exists in the time slot corresponding to the bit position, and embodiments of the present application do not make any limitation in this regard. In the embodiments of the present application, the value of the bit position being 1 is taken as an example to be described.

[0121] In a possible implementation, the number of bit positions with the value of 1 in the second information is the same as the number N of SLIVs included in the first information. As an example but not limitation, Figure 4 is an example of the correspondence between the bit map of the embodiments of the present application and the time domain resource of the shared channel corresponding to the SLIV, as Figure 4 As shown in the upper half, the first information includes 6 SLIVs, and the corresponding second information includes 6 bit positions with the value of 1. Figure 1 The first information includes 6 SLIVs, and the second information includes a bit map of 6 bit positions with the value of 1, and the distribution of the time domain resource of the shared channel corresponding to the 6 SLIVs is as shown in Figure 4 .

[0122] In a possible implementation, the number of bit positions with the value of 1 in the second information can be more than the number N of SLIVs included in the first information. Optionally, only the first N bit positions with the value of 1 in the bit map are used to correspond to the N SLIVs. It should be understood that in this case, one bit map included in the second information can correspond to multiple first information, in other words, it can be determined flexibly which bit positions in the bit map are used according to the number of SLIVs included in the first information. As an example but not limitation, as Figure 4 The lower half, in which the first information includes 6 SLIVs, and the corresponding second information includes bit positions with the value of 1. Figure 2 {110110111110…}. It can be known from Figure 4 that when the number of bit positions with the value of 1 in the bit map is more than N, only the part of the bit map corresponding to the first N bit positions with the value of 1 is used for correspondence, and in Figure 4 the lower half, only the first 8 bit positions are used to correspond to the 6 SLIVs included in the first information.

[0123] It should be noted that, in the above embodiments, the bits of the bitmap correspond to the first SLIV to the last SLIV included in the first information in the order from front to back, or in the order from left to right. Alternatively, the bits of the bitmap can correspond to the first SLIV to the last SLIV included in the first information in the order from back to front, or in the order from right to left. The embodiments of the present application do not limit this.

[0124] It should be noted that, as shown in Figure 4 , the box with the SLIV written therein indicates that there is a time-domain resource of the shared channel in the time slot corresponding to the box, and the box with nothing written therein indicates that there is no time-domain resource of the shared channel in the time slot corresponding to the box. It should be understood that the presence of the shared channel in the time slot does not necessarily mean that the time-domain resource of the shared channel occupies the time slot, and the size of the time-domain resource of the shared channel occupying the time slot is determined by the value of the SLIV. In the schematic diagram of the embodiments of the present application, only the box with the SLIV written therein indicates that there is a time-domain resource of the shared channel in the time slot, but the size of the time-domain resource of the shared channel occupying the time slot is not limited.

[0125] Alternatively, one bitmap can include P bits, and the value of P can be less than or equal to a first threshold. The first threshold can be in units of time slots, or in units of symbols, or in units of time slots corresponding to absolute time. The first threshold is set such that the channel conditions of the time-domain resources of the shared channels corresponding to the N SLIVs included in the first information do not change greatly, and the same modulation and coding scheme can be used for the N SLIVs, which is beneficial to reducing the load of the modulation and coding scheme indicated in the DCI.

[0126] In some embodiments, if the N SLIVs included in the first information are not associated with the second information, i.e., not associated with the bitmap, it indicates that the time-domain resources of the shared channels corresponding to the N SLIVs are continuous, or there is no interval between the time-domain resources of the shared channels corresponding to the N SLIVs. It should be understood that the meaning of not continuous or having an interval is that, when the time-domain resources corresponding to different SLIVs are in different time slots, the difference between the indexes of the time slot in which the time-domain resource of the shared channel corresponding to the previous SLIV is located and the time slot in which the time-domain resource of the shared channel corresponding to the next SLIV is located is greater than 1. Alternatively, the offset value of the time slot in which the time-domain resource of the shared channel corresponding to the first SLIV in the N SLIVs is located can be predefined or configured by the time-domain resource configuration information, for example, configured by RRC signaling.

[0127] In some embodiments, the first information and the second information are included in the first entry, the second information includes a bitmap of bits, and the number of bits included in the bitmap is the same as the number N of SLIVs included in the first information, i.e., the bitmap includes N bits, each bit corresponding to one SLIV included in the first information, and the value of each bit indicates whether the corresponding SLIV is valid. If the value of a bit indicates that the corresponding SLIV is valid, the time domain resources of the shared channel corresponding to the corresponding SLIV exist in the time slot corresponding to the bit. If the value of a bit indicates that the corresponding SLIV is invalid, the time domain resources of the shared channel corresponding to the corresponding SLIV do not exist in the time slot corresponding to the bit, i.e., the corresponding SLIV is invalid. Optionally, the value of a bit can be 1 to indicate that the corresponding SLIV is valid, and the value of a bit can be 0 to indicate that the corresponding SLIV is invalid.

[0128] In some embodiments, the first information is included in the first entry, and the TDRA table is associated with a second information or the plurality of first entries in the TDRA table are associated with a second information, and the second information includes a bitmap of bits, which can include max(Ni) bits, where max(Ni) represents the maximum number of SLIVs included in the first information of the plurality of first entries. Each bit in the bitmap corresponds to one SLIV included in the first information, and the value of each bit indicates whether the corresponding SLIV is valid. If the value of a bit indicates that the corresponding SLIV is valid, the time domain resources of the shared channel corresponding to the corresponding SLIV exist in the time slot corresponding to the bit. If the value of a bit indicates that the corresponding SLIV is invalid, the time domain resources of the shared channel corresponding to the corresponding SLIV do not exist in the time slot corresponding to the bit. If max(Ni) is greater than N in the first information, only part of the bits, such as the first N bits, correspond to the N SLIVs in the first information. Optionally, the value of a bit can be 1 to indicate that the corresponding SLIV is valid, and the value of a bit can be 0 to indicate that the corresponding SLIV is invalid.

[0129] S320, the network device sends time domain resource indication information to the terminal device.

[0130] Specifically, the time domain resource indication information can be carried in DCI signaling.

[0131] In some embodiments, the time domain resource indication information can be used to indicate a first entry in the time domain resource configuration information, the first entry includes a first information and a second information, the first information includes N SLIVs, and the second information includes a bitmap of bits.

[0132] In some embodiments, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, the first table item includes a first information, the first information includes N SLIVs, the first table item is associated with a second information, and the second information includes a bit map. It should be noted that the second information associated with the first table item can also be associated with other first table items. The second information can be predefined or configured by the network device.

[0133] In some embodiments, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, the first table item includes a first information, the first table item includes N SLIVs. The time domain resource indication information can also be used to indicate a bit map in a set of bit maps. The set of bit maps can be predefined or configured by the network device.

[0134] S330, the network device determines the time domain resource of the shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0135] Specifically, the network device determines the time domain resource of the downlink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0136] S340, the network device transmits the shared channel to the terminal device on the time domain resource of the shared channel.

[0137] Specifically, the network device transmits the shared channel to the terminal device on the time domain resource of the downlink shared channel.

[0138] S350, the terminal device determines the time domain resource of the shared channel according to the time domain resource configuration information and the time domain resource indication information transmitted by the network device.

[0139] Specifically, the terminal device determines the time domain resource of the downlink shared channel according to the time domain resource configuration information and the time domain resource indication information transmitted by the network device.

[0140] S360, the terminal device receives the shared channel transmitted by the network device on the time domain resource of the shared channel.

[0141] Specifically, the terminal device receives the shared channel transmitted by the network device on the time domain resource of the downlink shared channel.

[0142] It should be noted that the determination method of the time domain resource of the uplink control channel corresponding to the uplink transmission is similar to the above description. The corresponding steps are described simply below. It should be understood that the corresponding contents in each step are similar to those of the downlink transmission, and can be referred to the description of the above embodiments. The determination method of the time domain resource of the control information corresponding to the uplink transmission is as follows:

[0143] SS310, the network device sends time domain resource configuration information to the terminal device.

[0144] SS320, the network device sends time domain resource indication information to the terminal device.

[0145] SS330, the terminal device determines the time domain resource of the uplink shared channel according to the time domain resource indication information and the time domain resource configuration information.

[0146] SS340, the terminal device sends the shared channel to the network device on the time domain resource of the uplink shared channel.

[0147] SS350, the network device determines the time domain resource of the uplink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0148] SS360, the network device receives the shared channel sent by the terminal device on the time domain resource of the uplink shared channel.

[0149] The determination method of the time domain resource of the uplink shared channel is the same as the determination method of the time domain resource of the downlink channel, and the related description can be referred to.

[0150] The method for determining the time domain resource provided by the embodiment of the application is that one bit map corresponds to N SLIVs in the first information, each bit in the bit map corresponds to a time slot, and the value of the bit is used to determine whether there is a time domain resource of the shared channel corresponding to the SLIV in the time slot corresponding to the bit. By this method, flexible non-continuous resource scheduling is realized, and signaling overhead is saved to a certain extent.

[0151] Figure 5 is a schematic diagram of another example of the method for determining the time domain resource of the embodiment of the application. As shown in Figure 5 the method 500 includes:

[0152] It should be understood that the time domain resource of the shared channel in the embodiment of the application can correspond to the time domain resource of the uplink shared channel of the uplink transmission, or can correspond to the time domain resource of the downlink shared channel of the downlink transmission. The method for determining the time domain resource of the embodiment of the application is introduced below by taking the downlink transmission as an example.

[0153] S510, the network device sends time domain resource configuration information to the terminal device, and the time domain resource configuration information is used to configure the SLIV associated with the time slot offset value.

[0154] Optionally, the time domain resource configuration information can be carried in the RRC signaling.

[0155] Specifically, the time domain resource configuration information can include a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N SLIVs. Each SLIV is used to indicate the time domain resource of a shared channel in a slot. Specifically, each SLIV indicates the time domain resource of the shared channel corresponding to the SLIV in the slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the shared channels corresponding to the N SLIVs in the slot.

[0156] Specifically, each of the N SLIVs included in the first information can be associated with a slot offset value, or can not be associated with a slot offset value. It should be understood that the association of the slot offset value of each of the N SLIVs can determine the distribution of the time domain resources of the shared channels corresponding to the N SLIVs.

[0157] In some embodiments, none of the N SLIVs included in the first information is associated with a slot offset value, indicating that the slots in which the time domain resources of the shared channels corresponding to the N SLIVs are located are continuous. Optionally, the slot in which the time domain resources of the shared channel corresponding to the first SLIV of the N SLIVs are located is determined by a predefined slot offset value. It should be understood that the continuous slots indicate that there is no interval between the time domain resources of the shared channels corresponding to any two adjacent SLIVs in the N SLIVs, and the time domain resources of the shared channels corresponding to the N SLIVs only need to be arranged continuously in the order of the symbols in the slot indicated by the SLIV. The meaning of the interval can be that the index difference between the slot in which the time domain resources of the shared channel corresponding to the previous SLIV are located and the slot in which the time domain resources of the shared channel corresponding to the next SLIV are located is greater than 1.

[0158] In some embodiments, only one of the N SLIVs included in the first information is associated with a slot offset value, indicating that the slots in which the time domain resources of the shared channels corresponding to the N SLIVs are located are continuous. The meaning of the continuous slots is similar to that of the above embodiments, and reference can be made to the related description of the above embodiments. The slot in which the time domain resources of the shared channel corresponding to the first SLIV of the N SLIVs are located is determined by the slot offset value associated with the one SLIV.

[0159] In some embodiments, more than one of the N SLIVs included in the first information is associated with a respective time slot offset value, e.g., only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, indicating that time slots in which time domain resources of shared channels corresponding to the J+1th SLIV to the Kth SLIV are located are continuous, time slots in which time domain resources of shared channels corresponding to the Kth SLIV to the Nth SLIV (when N = K, the Kth SLIV to the Nth SLIV only contains one SLIV) are located are determined by the time slot offset value associated with the Kth SLIV, time domain resources of shared channels corresponding to the J+1th SLIV to the K-1th SLIV are located before and continuous with time domain resources of shared channels corresponding to the Kth SLIV, there is a gap between the Jth SLIV and the J+1th SLIV, time domain resources of shared channels corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, and time domain resources of shared channels corresponding to the 1st SLIV to the Jth SLIV are continuous. The meaning of the gap is the same as that of the above embodiments.

[0160] In some embodiments, more than one of the N SLIVs included in the first information is associated with a respective time slot offset value, e.g., only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, indicating that time slots in which time domain resources of shared channels corresponding to the J+1th SLIV to the Kth SLIV are located are continuous, time slots in which time domain resources of shared channels corresponding to the Kth SLIV to the Nth SLIV (when N = K, the Kth SLIV to the Nth SLIV only contains one SLIV) are located are determined by the time slot offset value associated with the Kth SLIV, time domain resources of shared channels corresponding to the J+1th SLIV to the K-1th SLIV are located before and continuous with time domain resources of shared channels corresponding to the Kth SLIV, there is a gap between the Jth SLIV and the J+1th SLIV, time domain resources of shared channels corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, and time domain resources of shared channels corresponding to the 1st SLIV to the Jth SLIV are continuous. The meaning of the gap is the same as that of the above embodiments.

[0161] In some embodiments, the first information comprises that more than one of the N SLIVs is associated with a respective time slot offset value, for example, only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, time domain resources of the shared channel corresponding to the 1th to Jth SLIVs are continuous, time domain resources of the shared channel corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, time domain resources of the shared channel corresponding to the 1th to J-1th SLIVs are before and continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, time domain resources of the shared channel corresponding to the Kth SLIV are determined by the time slot offset value corresponding to the Kth SLIV, and time domain resources of the shared channel corresponding to the Kth to Nth SLIVs are continuous. It should be noted that if K-J = 1, there is an interval between the time domain resources of the shared channel corresponding to the Jth SLIV and the Kth SLIV, if K-J = 2X, the time domain resources of the shared channel corresponding to the J+1th to J+Xth SLIVs are continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, the time domain resources of the shared channel corresponding to the K-X+1th to K-1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Kth SLIV, and there is an interval between the time domain resources of the shared channel corresponding to the J+Xth SLIV and the K-X+1th SLIV. If K-J = 2X+1, the time domain resources of the shared channel corresponding to the J+1th to J+X+1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, the time domain resources of the shared channel corresponding to the K-X+1th to K-1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Kth SLIV, and there is an interval between the time domain resources of the shared channel corresponding to the J+X+1th SLIV and the K-X+1th SLIV. The meaning of the interval is the same as that of the above embodiments.

[0162] It should be noted that if the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the first SLIV in the N SLIVs, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the first SLIV are located and the first symbol of the time slot where the DCI is located. If the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the SLIV other than the first SLIV, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the SLIV are located and the first symbol of the time slot where the DCI is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the SLIV are located and the first symbol of the time slot where the shared channel corresponding to the SLIV before the SLIV is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the SLIV are located and the first symbol of the time slot corresponding to the time slot offset value associated with the SLIV before the SLIV.

[0174] It should be noted that the determination method of the time domain resource of the uplink control channel corresponding to the uplink transmission is similar to the above description. The corresponding steps are briefly described below. It should be understood that the corresponding content in each step is similar to that of the downlink transmission.

[0183] Figure 6 is another example of the method for determining the time domain resource of the present application. As shown in Figure 6 the method 600 includes:

[0184] It should be understood that the time domain resources of the shared channel in the embodiments of the present application can correspond to the time domain resources of the uplink shared channel of the uplink transmission, or can correspond to the time domain resources of the downlink shared channel of the downlink transmission. The method for determining the time domain resources in the embodiments of the present application is introduced below by taking the downlink transmission as an example.

[0185] In S610, the network device sends time domain resource configuration information to the terminal device, where the time domain resource configuration information is used to configure SLIV and a slot offset value.

[0186] Optionally, the time domain resource configuration information can be carried in RRC signaling.

[0187] Specifically, the time domain resource configuration information can be a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes a first information and a second information.

[0188] Specifically, the first information includes N SLIVs. Each SLIV is used to indicate the time domain resources of a shared channel in a slot. Specifically, each SLIV indicates which symbols the shared channel resource corresponding to the SLIV is located in a slot, and N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the shared channels corresponding to the N SLIVs in the slot.

[0189] Specifically, the second information includes M slot offset values. There is a preset association relationship between the slot offset values of the shared channels corresponding to the N SLIVs and the M slot offset values.

[0190] In some embodiments, the preset association relationship is as follows: the N SLIVs are divided into M groups. If N / M is divisible, the number of SLIVs in each group is N / M. If N / M is not divisible and the remainder is X, then the number of SLIVs in each of the first X groups is floor(N / M)+1 or (NX) / M+1, and the number of SLIVs in the (X+1)th group and subsequent groups is floor(N / M) or (NX) / M. floor(·) represents rounding down from the · symbol. There is an interval between the time-domain resources of the shared channel corresponding to each group of SLIVs. This interval means that the index difference between the first symbol of the time slot containing the time-domain resource of the shared channel corresponding to the last SLIV of the previous group and the first symbol of the time slot containing the time-domain resource of the shared channel corresponding to the first SLIV of the next group is greater than 1. There are no gaps between the time-domain resources of the shared channel corresponding to one or more SLIVs in each group. In other words, the time slots of the time-domain resources of the shared channel corresponding to one or more SLIVs in each group are continuous (if multiple SLIVs can be distributed in the same time slot, then the time slots of the time-domain resources of the shared channel corresponding to one or more SLIVs in each group can also be the same or continuous). The time slot offset value of the time-domain resources of the shared channel corresponding to the first SLIV in the Y-th group corresponds to the Y-th time slot offset value in the second message. M is a positive integer less than or equal to N, and Y is a positive integer greater than or equal to 1 and less than or equal to M.

[0191] As an example and not a limitation, when the second message includes a timeslot offset value, it indicates that the time-domain resources of the shared channels corresponding to the N SLIVs included in the first message are continuous, wherein the time-domain resources of the shared channel corresponding to the first SLIV are determined by the first timeslot offset value. Figure 7 This is an example of a preset association between the time slot offset value and the time domain resources of the shared channel corresponding to SLIV in an embodiment of this application. For example... Figure 7 As shown in Case 1, N is set to 7.

[0192] As an example, not a limitation, when the second message includes two time slot offset values, it indicates that the N SLIVs included in the first message are divided into two groups, and there is an interval between the time domain resources of the shared channel corresponding to the two groups of SLIVs. Assuming the last SLIV in the first group is the J-th SLIV, and the first SLIV in the second group is the (J+1)-th SLIV, then J = ceil(N / 2), where ceil represents rounding up. That is, if N / 2 is divisible, J = N / 2; if N / 2 is not divisible and the remainder is X, then J = (NX) / 2 + 1. Figure 7As shown in case 2, if N equals 7, J=4, J+1=5, it means that when two slot offset values are included in the second message, the first 4 SLIVs are the first group and the 5th to 7th SLIVs are the second group, wherein the first SLIV in the first group, i.e. the 1st SLIV in the N SLIVs, corresponds to the first slot offset value in the second message, and the time domain resource of the shared channel corresponding to the 1st SLIV is determined according to the first slot offset value, and the time domain resources of the shared channels corresponding to the 2nd to 4th SLIVs are continuous with the time domain resource of the shared channel corresponding to the 1st SLIV. The first SLIV in the second group, i.e. the 5th SLIV in the N SLIVs, corresponds to the second slot offset value in the second message, and the time domain resource of the shared channel corresponding to the 5th SLIV is determined according to the second slot offset value, and the time domain resources of the shared channels corresponding to the 6th to 7th SLIVs are continuous with the time domain resource of the shared channel corresponding to the 5th SLIV.

[0193] As an example but not limitation, when three slot offset values are included in the second message, it means that the N SLIVs included in the first message are divided into three groups, and there is an interval between the time domain resources of the shared channels corresponding to the three groups of SLIVs, as shown in Figure 7Case 3, where it is assumed that the last SLIV in the first group is the Jth SLIV, and the last SLIV in the second group is the Kth SLIV, where J = ceil(N / 3) and K = ceil((N-J) / 2) + J, where ceil(A / B) means rounding up, i.e., if the value inside can be divided by an integer, taking the integer quotient, if the value inside cannot be divided by an integer, taking the integer quotient of (A-C) / B + 1, C = A%B, i.e., the remainder of A divided by B. If N is equal to 7, J = 3, and K = 5, it means that when three time slot offset values are included in the second message, the first to third SLIVs are the first group, the fourth to fifth SLIVs are the second group, and the sixth to seventh SLIVs are the third group. Among them, the first SLIV in the first group, i.e., the first SLIV in the N SLIVs, corresponds to the first time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the first SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the second and third SLIVs are continuous with the time domain resource of the shared channel corresponding to the first SLIV. The first SLIV in the second group, i.e., the fourth SLIV in the N SLIVs, corresponds to the second time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the fourth SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the fifth SLIV are continuous with the time domain resource of the shared channel corresponding to the fourth SLIV. The first SLIV in the third group, i.e., the sixth SLIV in the N SLIVs, corresponds to the third time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the sixth SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the seventh SLIV are continuous with the time domain resource of the shared channel corresponding to the sixth SLIV.

[0194] It should be noted that in the above examples, the SLIVs in the blocks indicate that there is a time domain resource of a shared channel corresponding to an SLIV at this position, and the size of the block cannot represent the size of the time domain resource, and the size of the interval also cannot represent the size of the time slot offset value. The values of the time slot offset values and the values of the SLIVs in the above embodiments are determined. This application does not limit this.

[0195] In some embodiments, the one second information includes M time slot offset values, and the first information includes N SLIVs, and the number of N SLIVs is N, and the rule indicated by the pre-defined or time domain resource indication information is used to determine that the first m time slot offset values in the M time slot offset values are effective. Optionally, the second information can be configured for each first information, or one second information can be configured for all first information including first information in the TDRA resource table.

[0196] By way of example, and without limitation, the pre-defined or pre-configured rule can be:

[0197] (a) When the number of SLIVs included in the first information is less than or equal to 2, the first of the M time slot offset values takes effect, the time domain resources corresponding to the SLIVs included in the first information are continuous, and the first of the M time slot offset values is used to determine the time domain resources of the shared channel corresponding to the first SLIV in the first information.

[0198] (b) When the number of SLIVs included in the first information is less than or equal to 4, the first two of the M time slot offset values take effect, there is an interval between the time domain resources of the shared channels corresponding to the SLIVs included in the first information, and the distribution of the time domain resources can be determined according to the preset grouping rule.

[0199] (c) When the number of SLIVs included in the first information is less than or equal to 8, the first three of the M time slot offset values take effect, there are two intervals between the time domain resources of the shared channels corresponding to the SLIVs included in the first information, and the distribution of the time domain resources can be determined according to the preset grouping rule.

[0200] It should be noted that if the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the first SLIV of the N SLIVs, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the first SLIV are located and the first symbol of the time slot where the DCI is located. If the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the SLIV other than the first SLIV, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot where the DCI is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot where the shared channel corresponding to the SLIV before the associated SLIV is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot corresponding to the time slot offset value associated with the SLIV before the associated SLIV.

[0219] The determination method of the time domain resource of the uplink shared channel is the same as that of the time domain resource of the downlink channel, and the related description can be referred to.

[0220] The method for determining the time domain resource provided in the embodiments of the present application groups the SLIVs in the first information according to the number of time slot offset values through the preset association relationship, and the time slot offset value of each group of SLIVs is determined by the time slot offset value associated with the group of SLIVs, thereby providing a flexible method for determining discontinuous resources, and to some extent, signaling overhead is saved.

[0221] Figure 8 is a schematic diagram of another example of the method for determining the time domain resource of the present application. As shown in Figure 8 the method 800 includes:

[0222] It should be understood that the time domain resource of the shared channel in the embodiments of the present application can correspond to the time domain resource of the uplink shared channel of the uplink transmission, or can correspond to the time domain resource of the downlink shared channel of the downlink transmission. The method for determining the time domain resource in the embodiments of the present application will be introduced below taking the downlink transmission as an example.

[0223] S810, the network device sends time domain resource configuration information to the terminal device, and the time domain resource configuration information is used to configure SLIV and a pattern set.

[0224] Optionally, the time domain resource configuration information can be carried in the radio resource control (RRC) signaling.

[0225] Specifically, the time domain resource configuration information can include a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N SLIVs. Each SLIV is used to indicate the time domain resource of a shared channel in a time slot. Specifically, each SLIV indicates which symbols the time domain resource of the shared channel corresponding to the SLIV is located in a time slot, and N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the N shared channels in the time slot.

[0226] In some embodiments, the network device can define or configure a plurality of pattern sets in advance, wherein each pattern set includes a plurality of patterns, each pattern corresponds to the time domain resource distribution of a shared channel with a number of SLIVs, and different patterns correspond to different time domain resource distributions of shared channels with different numbers of SLIVs.

[0227] As an example but not limitation, the plurality of pattern sets can be as shown in Figure 9 Figure 9 Each pattern in each pattern set shown corresponds to a time-domain resource distribution of a shared channel of a number of SLIVs. Figure 9 Three pattern sets are shown, wherein, Figure 9 (a) of FIG. 1 shows that the time-domain resources of the shared channel corresponding to the N SLIVs are continuous, or no gap exists. Figure 9 (b) of FIG. 1 shows that at most one gap exists between the time-domain resources of the shared channel corresponding to the N SLIVs, and the existence or nonexistence of the gap is determined by the number of SLIVs. Figure 9 (c) of FIG. 1 shows that at most three gaps exist between the time-domain resources of the shared channel corresponding to the N SLIVs, and the specific number of gaps is determined by the number of SLIVs. For example, when corresponding to the pattern set shown in (c) of FIG. 1, if the number of SLIVs is 7, the time-domain resource distribution of the shared channel corresponding to the seventh row shown in (c) of FIG. 1 is determined. Figure 9 Figure 9 Figure 9 It should be understood that in (c) of FIG. 1, the SLIV written in the block indicates that there is a time-domain resource of the shared channel at this position, and no SLIV written in the block indicates that this is a gap, and the size of the block does not represent the size of the resource or the gap.

[0228] It should be noted that the distribution rule of the time-domain resources of the shared channel corresponding to the SLIVs in the predefined or configured pattern set can be similar to the preset rule in method 600, or other distribution rules can be used. The pattern set mentioned in the embodiment is only an example, and the present application does not limit this.

[0229] It should be noted that which pattern set to use can be indicated by the time-domain resource indication information, or it can be default.

[0230] It should be noted that the existence of the gap indicates that the index difference between the time slot where the time-domain resource of the shared channel corresponding to the previous SLIV is located and the time slot where the time-domain resource of the shared channel corresponding to the next SLIV is located is greater than 1, and the specific difference value of the gap can be default or indicated by the time-domain resource indication information.

Optionally, the time-domain resource indication information can also be used to indicate a gap value. Optionally, the time-domain resource indication information can also be used to indicate a pattern set.​​​

[0234] It should be noted that when the time domain resource indication information indicates a pattern set, it can be considered that a certain pattern set is defaulted when not indicated, which can save the signaling load of the network side.

[0235] It should be noted that the pattern set indicated by the time domain resource indication information can be one of the plurality of pattern sets configured in the time domain configuration information, wherein the plurality of pattern sets configured can not include the default pattern set.

It should be understood that the corresponding contents in each step are similar to those of the downlink transmission, and reference can be made to the description of the above embodiments.

[0257] Specifically, the time domain resource configuration information can include a TDRA table, and the TDRA table includes a plurality of table entries (the plurality of table entries can be an item or a list). At least one first table entry includes first information and a second information.

[0258] Specifically, the first information includes N SLIVs. Each SLIV is used to indicate the time domain resource of one shared channel in one time slot. Specifically, each SLIV indicates in which symbols the time domain resource of the shared channel corresponding to the SLIV is located in the time slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the shared channels corresponding to the N SLIVs in the time slot.

[0259] Specifically, the second information includes M length values, each of which corresponds to the number of SLIVs included in a group of SLIVs. It should be understood that the time domain resources of the shared channels of the SLIVs in each group are continuous, or there is no interval, and there is an interval between the time domain resources of the shared channels corresponding to each adjacent two groups of SLIVs. The meaning of the interval can be that the index difference between the time slot where the time domain resource of the shared channel corresponding to the last SLIV of the previous group of SLIVs is located and the time slot where the time domain resource of the shared channel corresponding to the first SLIV of the next group of SLIVs is located is greater than 1.

[0289] In some embodiments, the first information in the first entry is associated with a second information, which includes a bit map, each bit in the bit map corresponding to a time slot, and the value of each bit in the bit map indicating whether there is a time domain resource of a shared channel indicated by one of N SLIVs in the time slot corresponding to the bit.

[0290] Optionally, a second piece of information associated with the first information may be located in the same first table entry as the first information; in other words, the first table entry includes both the first information and the second information.

[0291] In some embodiments, the first information included in multiple first entries is associated with the same second information. The second information includes a bitmap, where each bit in the bitmap corresponds to a time slot, and the value of each bit in the bitmap indicates whether there is a time-domain resource of a shared channel indicated by one of N SLIVs in the time slot corresponding to that bit.

[0292] Optionally, the same second information associated with multiple first pieces of information included in multiple entries of the TDRA table may not be included in the first entry together with the first information in each first entry. In other words, the same second information associated with multiple first pieces of information in multiple entries may be configured separately outside the TDRA table, or predefined.

[0293] Optionally, the first information of all first entries in the TDRA table is associated with the same second information. This second information can be predefined, or it can be configured separately outside the TDRA table.

[0294] In some embodiments, the first entry includes a first piece of information associated with a set of bitmaps, the set of bitmaps including multiple bitmaps, each bitmap corresponding to a second piece of information, each bit in the bitmap corresponding to a time slot, and the value of each bit in a bitmap corresponding to a second piece of information indicates whether there is a time domain resource of a shared channel indicated by one of N SLIVs in the time slot corresponding to that bit.

[0295] Optionally, the set of bitmaps can be predefined by the protocol.

[0296] Optionally, the set of bitmaps can be configured using time-domain resource configuration information.

[0297] Optionally, one of the bitmaps in the set of bitmaps may be indicated by time-domain resource indication information, for example, by DCI signaling.

[0298] In the above embodiment, the value of the bit is 1 to indicate that the time domain resource of the shared channel indicated by one of the N SLIVs exists in the time slot corresponding to the bit, and the value of the bit is 0 to indicate that the time domain resource of the shared channel does not exist in the time slot corresponding to the bit. As an example but not limitation, the bits in the bitmap are distributed in sequence, and the distribution sequence of the bits with the value of 1 in the bitmap corresponds to the arrangement sequence of the N SLIVs included in the first information. For example, the time domain resource of the shared channel corresponding to the second SLIV of the N SLIVs is located in the time slot corresponding to the second bit with the value of 1 in the bitmap.

[0299] It should be noted that the value of the bit can also be 0 to indicate that the time domain resource of the shared channel indicated by one of the N SLIVs exists in the time slot associated with the bit, and the embodiment of the present application does not limit this. In the embodiment of the present application, the value of the bit is 1 as an example.

[0300] Optionally, the number of bits with the value of 1 in the second information is the same as the number N of SLIVs included in the first information. As an example but not limitation, as shown in the upper half of FIG. 6, the first information includes 6 SLIVs, and the corresponding second information includes the bitmap of bits with the value of Figure 12 As shown in the upper half of FIG. 6, the first information includes 6 SLIVs, and the corresponding second information includes the bitmap of bits with the value of Figure 4 {11011011}, and the distribution of the time domain resource of the shared channel corresponding to the 6 SLIVs in the first information and the 6 SLIVs determined by the bitmap of bits in the second information is as shown in the upper half of FIG. 6. Figure 1

[0301] Optionally, the number of bits with the value of 1 in the second information can be more than the number N of SLIVs included in the first information. Optionally, only the bits with the value of 1 in the first bit to the Nth bit of the bitmap are required to correspond to the N SLIVs. It should be understood that in this case, one bitmap of bits in the second information can correspond to multiple first information, in other words, it can be determined flexibly which bits in the bitmap of bits are used according to the number of SLIVs included in the first information. As an example but not limitation, as shown in the lower half of FIG. 6, the first information includes 6 SLIVs, and the corresponding second information includes the bitmap of bits with the value of Figure 4 As shown in the lower half of FIG. 6, the first information includes 6 SLIVs, and the corresponding second information includes the bitmap of bits with the value of Figure 4 {110110111110…}. As can be seen from the figure, when the number of bits with the value of 1 in the bitmap of bits is more than N, only the part of the bitmap of bits corresponding to the first N bits with the value of 1 is required to correspond, and in the lower half of FIG. 6, only the first 8 bits corresponding to the 6 SLIVs are taken. Figure 2

[0302] ​​It should be noted that, in the above embodiments, the order of the bits in the bitmap from front to back, or from left to right, corresponds sequentially to the first SLIV to the last SLIV included in the first information. Optionally, the order of the bits in the bitmap from back to front, or from right to left, may also correspond sequentially to the first SLIV to the last SLIV included in the first information.

[0303] It should be noted that, as Figure 4 As shown, boxes containing "SLIV" indicate the presence of shared channel time-domain resources in the corresponding time slot, while empty boxes indicate the absence of shared channel time-domain resources in the corresponding time slot. It should be understood that the presence of a shared channel in a time slot does not necessarily mean that the shared channel's time-domain resources completely occupy the time slot; this is determined by the value of "SLIV." In the schematic diagram of this embodiment, only boxes containing "SLIV" indicate the presence of shared channel time-domain resources in the time slot, but the size of the shared channel's time-domain resources occupying the time slot is not limited.

[0304] Optionally, a bitmap may include P bits, where the value of P can be less than a first threshold. This first threshold can be a time slot, a symbol, or a time slot corresponding to absolute time. Setting this first threshold ensures that the channel conditions of the shared channel time-domain resources of the N SLIVs corresponding to the first information do not change significantly. These N SLIVs can use the same modulation and coding scheme, which helps reduce the load on the DCI indicating the modulation and coding scheme.

[0305] In some embodiments, if the N SLIVs included in the first information do not have associated bitmaps, it indicates that the time-domain resources of the shared channel corresponding to the N SLIVs are continuous, or that there is no gap between the time-domain resources of the shared channel corresponding to the N SLIVs. It should be understood that discontinuity or gaps mean that when the time-domain resources corresponding to different SLIVs are in different time slots, the difference between the time slot where the time-domain resources of the shared channel corresponding to the previous SLIV are located and the time slot where the time-domain resources of the shared channel corresponding to the next SLIV are located is greater than 1. Optionally, the time slot offset value of the shared channel time-domain resource corresponding to the first SLIV among the N SLIVs can be predefined or configured by time-domain resource configuration information, for example, by RRC signaling.

[0306] In some embodiments, the first information and the second information are included in the first entry, the second information includes a bitmap including a same number of bits as the number N of SLIVs included in the first information, i.e., the bitmap includes N bits, each bit corresponding to one SLIV included in the first information, and a value of each bit indicating whether the corresponding SLIV is valid or not, if the value of the bit indicates that the corresponding SLIV is valid, time domain resources of a shared channel corresponding to the corresponding SLIV exist in a time slot corresponding to the bit, and if the value of the bit indicates that the corresponding SLIV is not valid, time domain resources of the shared channel corresponding to the corresponding SLIV do not exist in the time slot corresponding to the bit. Optionally, the value of the bit can be 1 to indicate that the corresponding SLIV is valid, and the value of the bit can be 0 to indicate that the corresponding SLIV is not valid. In some embodiments, the first information is included in the first entry, and a second information is associated with the TDRA table or a plurality of first entries in the TDRA table, the second information includes a bitmap including max(Ni) bits, where max(Ni) represents the maximum number of SLIVs included in the first information of the plurality of first entries. Each bit in the bitmap corresponds to one SLIV included in the first information, and a value of each bit indicates whether the corresponding SLIV is valid or not, if the value of the bit indicates that the corresponding SLIV is valid, time domain resources of a shared channel corresponding to the corresponding SLIV exist in a time slot corresponding to the bit, and if the value of the bit indicates that the corresponding SLIV is not valid, time domain resources of the shared channel corresponding to the corresponding SLIV do not exist in the time slot corresponding to the bit. If max(Ni) is greater than N in the first information, only part of the bits, such as the first N bits, correspond to the N SLIVs in the first information. Optionally, the value of the bit can be 1 to indicate that the corresponding SLIV is valid, and the value of the bit can be 0 to indicate that the corresponding SLIV is not valid.

[0307] The transceiver 1210 is further configured to send time domain resource indication information to the terminal device.

[0308] Specifically, the time domain resource indication information can be carried in DCI signaling.

[0309] In some embodiments, the time domain resource indication information can be used to indicate a first entry in time domain resource configuration information, the first entry including a first information and a second information, the first information including N SLIVs, and the second information including a bitmap.

[0310] In some embodiments, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, the first table item includes a first information, the first information includes N SLIVs, the first table item is associated with a second information, and the second information includes a bit map. It should be noted that the second information associated with the first table item can also be associated with other first table items. The second information can be predefined or configured by the processing unit 1220.

[0311] In some embodiments, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, the first table item includes a first information, the first table information includes N SLIVs. The time domain resource indication information can also be used to indicate a bit map in a set of bit maps. The set of bit maps can be predefined or configured by the processing unit 1220.

[0312] The transceiver 1210 is further configured to send a message to the terminal device on the time domain resource of the shared channel.

[0313] Specifically, the transceiver 1210 sends a message to the terminal device on the time domain resource of the downlink shared channel.

[0314] It should be noted that the apparatus can also perform the determination of the time domain resource of the uplink control channel corresponding to the uplink transmission, which is similar to the above description. The corresponding steps are briefly described below, and it should be understood that the corresponding contents in each step are similar to those of the downlink transmission, and the description of the above embodiments can be referred to.

[0316] The transceiver 1210 is further configured to send time domain resource indication information to the terminal device.

[0317] The processing unit 1220 is configured to determine the time domain resource of the uplink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0318] The transceiver 1210 is further configured to receive information sent by the terminal device on the time domain resource of the uplink shared channel.

[0319] In some embodiments, the communication apparatus 1200 can be a terminal device in the above method embodiment 300, or a chip for implementing the functions of the terminal device in the above method embodiment. It should be understood that the communication apparatus 1200 can correspond to the steps corresponding to the terminal device in the method 300 of the embodiments of the present application. The communication apparatus 1200 includes:

[0320] The transceiver 1210 is configured to receive time domain resource configuration information sent by a network device.

[0321] The processing unit 1220 is configured to determine time domain resources of a shared channel according to the time domain resource configuration information and time domain resource indication information.

[0322] Optionally, the time domain resource configuration information can be carried in Radio Resource Control (RRC) signaling.

[0323] Specifically, the time domain resource configuration information can include a time domain resource allocation (TDRA) table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N start and length indicator values (SLIVs). Each SLIV is used to indicate the time domain resources of a shared channel in a slot. Specifically, each SLIV indicates the symbols in the slot where the time domain resources of the shared channel corresponding to the SLIV are located. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the N shared channels corresponding to the N SLIVs in the slot.

[0324] In some embodiments, the first information in the first table entry is associated with a second information, and the second information includes a bit map. Each bit in the bit map corresponds to a slot, and the value of each bit in the bit map indicates whether there is a shared channel in the slot corresponding to the bit.

[0325] Optionally, the second information associated with the first information can be located in the first table entry together with the first information, that is, the first table entry includes the first information and the second information.

[0326] In some embodiments, the first information included in the plurality of first table entries is associated with the same second information. The second information includes a bit map. Each bit in the bit map corresponds to a slot, and the value of each bit in the bit map indicates whether there is a shared channel in the slot corresponding to the bit.

[0327] Optionally, the same second information associated with the plurality of first information in the plurality of table entries in the TDRA table can not be included in the first table entry together with the first information in each first table entry, in other words, the same second information associated with the plurality of first information in the plurality of table entries can be separately configured outside the TDRA table, or predefined.

[0328] Optionally, the first information of all the first table entries in the TDRA table is associated with the same second information. The second information can be predefined, or the second information is separately configured outside the TDRA table.

[0329] In some embodiments, the first information included in the one first table entry is associated with a set of bitmaps, the set of bitmaps includes a plurality of bitmaps, each bitmap corresponds to one second information, each bit in the bitmap corresponds to one time slot, and the value of each bit in the bitmap corresponding to one second information indicates whether the time domain resource of the shared channel indicated by one SLIV of the N SLIVs exists in the time slot corresponding to the bit.

[0330] Optionally, the set of bitmaps can be predefined by the protocol.

[0331] Optionally, the time domain resource configuration information includes configuration information of the set of bitmaps.

[0332] Optionally, one bitmap in the set of bitmaps can be indicated by the time domain resource indication information, for example, can be indicated by DCI signaling.

[0333] In the above embodiments, the value of the bit can be 1 to indicate that the time domain resource of the shared channel indicated by one SLIV of the N SLIVs exists in the time slot corresponding to the bit, and the value of the bit can be 0 to indicate that the time domain resource of the shared channel does not exist in the time slot corresponding to the bit. As an example but not limitation, the bits in the bitmap are distributed in order, and the distribution order of the bits with value 1 in the bitmap corresponds to the arrangement order of the N SLIVs included in the first information, for example, the time domain resource of the shared channel corresponding to the second SLIV of the N SLIVs is located in the time slot corresponding to the second bit with value 1 in the bitmap.

[0334] It should be noted that the value of the bit can also be 0 to indicate that the time domain resource of the shared channel indicated by one SLIV of the N SLIVs exists in the time slot associated with the bit, and the embodiments of the present application do not limit this. In the embodiments of the present application, the value of the bit is taken as an example for description.

[0335] Optionally, the number of bits with value 1 in the second information is the same as the number N of SLIVs in the first information. As an example but not limitation, as shown in Figure 4 The first information includes 6 SLIVs, and the corresponding second information includes bits Figure 4 {11011011}, and the distribution of time domain resources of the shared channel corresponding to the 6 SLIVs in the first information and the 6 SLIVs determined by the bit pattern in the second information is as shown in Figure 1

[0336] Optionally, the number of bits with value 1 in the second information can be more than the number N of SLIVs in the first information. Optionally, only the first bit to the Nth bit of the bit pattern with value 1 is needed to correspond to the N SLIVs. It should be understood that in this case, one bit pattern in the second information can correspond to multiple first information, in other words, it can be determined flexibly which bits in the bit pattern are used according to the number of SLIVs in the first information. As an example but not limitation, as shown in Figure 4 The first information includes 6 SLIVs, and the corresponding second information includes bits Figure 4 {110110111110…}. As can be seen from the figure, when the number of bits with value 1 in the bit pattern is more than N, only the part of the bit pattern corresponding to the first N bits with value 1 is needed to correspond, and in Figure 2 The first 8 bits in the lower half are only used to correspond to the 6 SLIVs.

[0337] It should be noted that in the above embodiments, the order of the bits in the bit pattern from front to back, or from left to right, corresponds to the first SLIV to the last SLIV included in the first information in turn. Optionally, the order of the bits in the bit pattern from back to front, or from right to left, can also correspond to the first SLIV to the last SLIV included in the first information in turn.

[0338] It should be noted that as shown in Figure 4 The SLIV written in the box indicates that there is time domain resource of the shared channel in the time slot corresponding to the box, and the empty box indicates that there is no time domain resource of the shared channel in the time slot corresponding to the box. It should be understood that the existence of the shared channel in the time slot does not necessarily mean that the time domain resource of the shared channel occupies the time slot, and the size of the time domain resource of the shared channel occupying the time slot is not limited, which is only indicated by the box with SLIV in the schematic diagram of the embodiments of the present application.

[0339] ​Optionally, a bitmap may include P bits, where the value of P can be less than a first threshold. This first threshold can be a time slot, a symbol, or a time slot corresponding to absolute time. Setting this first threshold ensures that the channel conditions of the shared channel time-domain resources of the N SLIVs corresponding to the first information do not change significantly. These N SLIVs can use the same modulation and coding scheme, which helps reduce the load on the DCI indicating the modulation and coding scheme.

[0340] In some embodiments, if the N SLIVs included in the first information do not have associated bitmaps, it indicates that the time-domain resources of the shared channel corresponding to the N SLIVs are continuous, or that there is no gap between the time-domain resources of the shared channel corresponding to the N SLIVs. It should be understood that discontinuity or gaps mean that when the time-domain resources corresponding to different SLIVs are in different time slots, the difference between the time slot where the time-domain resources of the shared channel corresponding to the previous SLIV are located and the time slot where the time-domain resources of the shared channel corresponding to the next SLIV are located is greater than 1. Optionally, the time slot offset value of the shared channel time-domain resource corresponding to the first SLIV among the N SLIVs can be predefined or configured by time-domain resource configuration information, for example, by RRC signaling.

[0341] In some embodiments, the first information and the second information are included in the first entry, the second information includes a bitmap including a same number of bits as the number N of SLIVs included in the first information, i.e., the bitmap includes N bits, each bit corresponding to one SLIV included in the first information, and a value of each bit indicating whether the corresponding SLIV is valid, if the value of the bit indicates that the corresponding SLIV is valid, time domain resources of a shared channel corresponding to the corresponding SLIV exist in a time slot corresponding to the bit, and if the value of the bit indicates that the corresponding SLIV is invalid, time domain resources of the shared channel corresponding to the corresponding SLIV do not exist in the time slot corresponding to the bit. Optionally, the value of the bit can be 1 to indicate that the corresponding SLIV is valid, and the value of the bit can be 0 to indicate that the corresponding SLIV is invalid. In some embodiments, the first information is included in the first entry, and a second information is associated with the TDRA table or a plurality of first entries in the TDRA table, the second information includes a bitmap including max(Ni) bits, where max(Ni) represents the maximum number of SLIVs included in the first information of the plurality of first entries. Each bit in the bitmap corresponds to one SLIV included in the first information, and a value of each bit indicates whether the corresponding SLIV is valid, if the value of the bit indicates that the corresponding SLIV is valid, time domain resources of a shared channel corresponding to the corresponding SLIV exist in a time slot corresponding to the bit, and if the value of the bit indicates that the corresponding SLIV is invalid, time domain resources of the shared channel corresponding to the corresponding SLIV do not exist in the time slot corresponding to the bit. If max(Ni) is greater than N in the first information, only part of the bits, such as the first N bits, correspond to the N SLIVs in the first information. Optionally, the value of the bit can be 1 to indicate that the corresponding SLIV is valid, and the value of the bit can be 0 to indicate that the corresponding SLIV is invalid.

[0342] The transceiver 1210 is further configured to receive the time domain resource indication information sent by the network device.

[0343] Specifically, the time domain resource indication information can be carried in DCI signaling.

[0344] In some embodiments, the time domain resource indication information can be used to indicate a first entry in the time domain resource configuration information, the first entry includes a first information and a second information, the first information includes N SLIVs, and the second information includes a bitmap.

[0345] In some embodiments, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, the first table item includes a first information, the first information includes N SLIVs, the first table item is associated with a second information, and the second information includes a bit map. It should be noted that the second information associated with the first table item can also be associated with other first table items. The second information can be predefined or configured by the network device.

[0346] In some embodiments, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, the first table item includes a first information, the first table item includes N SLIVs. The time domain resource indication information can also be used to indicate a bit map in a set of bit maps. The set of bit maps can be predefined or configured by the network device.

[0347] The transceiver 1210 is further configured to receive, on the time domain resource of the downlink shared channel, a shared channel transmitted by the network device.

[0348] It should be noted that the apparatus can also perform the determination of the time domain resource of the uplink control channel corresponding to the uplink transmission, which is similar to the above description. The corresponding steps are briefly described below, and it should be understood that the corresponding contents in each step are similar to those of the downlink transmission, and the description of the above embodiments can be referred to.

[0349] The transceiver 1210 is configured to receive time domain resource configuration information transmitted by the network device.

[0350] The transceiver 1210 is further configured to receive time domain resource indication information transmitted by the network device.

[0351] The processing unit 1220 is configured to determine the time domain resource of the uplink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0352] The transceiver 1210 is further configured to transmit, to the network device, a message on the time domain resource of the uplink shared channel.

[0353] In some embodiments, the communication apparatus 1200 can be the network device in the above method embodiment 500, or can be a chip for implementing the functions of the network device in the above method embodiments. It should be understood that the communication apparatus 1200 can correspond to the steps corresponding to the network device in the method 500 of the embodiments of the present application. The communication apparatus 1200 includes:

[0354] The transceiver 1210 is configured to transmit, to the terminal device, time domain resource configuration information

[0355] The processing unit 1220 is configured to determine time domain resources of the shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0356] Optionally, the time domain resource configuration information can be carried in RRC signaling.

[0357] Specifically, the time domain resource configuration information can include a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N SLIVs. Each SLIV is used to indicate the time domain resources of a shared channel in a slot. Specifically, each SLIV indicates the time domain resources of the shared channel corresponding to the SLIV in the slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the shared channels corresponding to the N SLIVs in the slot.

[0358] Specifically, each of the N SLIVs included in the first information can be associated with a slot offset value, or can not be associated with a slot offset value. It should be understood that the association of the slot offset value of each of the N SLIVs can determine the distribution of the time domain resources of the shared channels corresponding to the N SLIVs.

[0359] In some embodiments, none of the N SLIVs included in the first information is associated with a slot offset value, indicating that the slots in which the time domain resources of the shared channels corresponding to the N SLIVs are located are continuous. Optionally, the slot in which the time domain resources of the shared channel corresponding to the first SLIV of the N SLIVs are located is determined by a predefined slot offset value. It should be understood that the continuous slots indicate that there is no interval between the time domain resources of the shared channels corresponding to any two adjacent SLIVs in the N SLIVs, and the time domain resources of the shared channels corresponding to the N SLIVs only need to be arranged continuously in the order of the symbols in the slot indicated by the SLIV. The meaning of the interval can be that the index difference between the slot in which the time domain resources of the shared channel corresponding to the previous SLIV are located and the slot in which the time domain resources of the shared channel corresponding to the next SLIV are located is greater than 1.

[0360] In some embodiments, only one of the N SLIVs included in the first information is associated with a slot offset value, indicating that the slots in which the time domain resources of the shared channels corresponding to the N SLIVs are located are continuous. The meaning of the continuous slots is similar to the above embodiments, and reference can be made to the related description of the above embodiments. The slot in which the time domain resources of the shared channel corresponding to the first SLIV of the N SLIVs are located is determined by the slot offset value associated with the one SLIV.

[0361] In some embodiments, more than one of the N SLIVs included in the first information is associated with a respective time slot offset value, e.g., only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, indicating that time slots in which time domain resources of shared channels corresponding to the J+1th SLIV to the Kth SLIV are located are continuous, time slots in which time domain resources of shared channels corresponding to the Kth SLIV to the Nth SLIV (when N = K, the Kth SLIV to the Nth SLIV only contains one SLIV) are located are determined by the time slot offset value associated with the Kth SLIV, time domain resources of shared channels corresponding to the J+1th SLIV to the K-1th SLIV are located before and continuous with time domain resources of shared channels corresponding to the Kth SLIV, there is a gap between the Jth SLIV and the J+1th SLIV, time domain resources of shared channels corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, and time domain resources of shared channels corresponding to the 1st SLIV to the Jth SLIV are continuous. The meaning of the gap is the same as that of the above embodiments.

[0362] In some embodiments, more than one of the N SLIVs included in the first information is associated with a respective time slot offset value, e.g., only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, indicating that time slots in which time domain resources of shared channels corresponding to the J+1th SLIV to the Kth SLIV are located are continuous, time slots in which time domain resources of shared channels corresponding to the Kth SLIV to the Nth SLIV (when N = K, the Kth SLIV to the Nth SLIV only contains one SLIV) are located are determined by the time slot offset value associated with the Kth SLIV, time domain resources of shared channels corresponding to the J+1th SLIV to the K-1th SLIV are located before and continuous with time domain resources of shared channels corresponding to the Kth SLIV, there is a gap between the Jth SLIV and the J+1th SLIV, time domain resources of shared channels corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, and time domain resources of shared channels corresponding to the 1st SLIV to the Jth SLIV are continuous. The meaning of the gap is the same as that of the above embodiments.

[0363] In some embodiments, the first information comprises that more than one of the N SLIVs is associated with a respective time slot offset value, for example, only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, time domain resources of the shared channel corresponding to the 1th to Jth SLIVs are continuous, time domain resources of the shared channel corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, time domain resources of the shared channel corresponding to the 1th to J-1th SLIVs are before and continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, time domain resources of the shared channel corresponding to the Kth SLIV are determined by the time slot offset value corresponding to the Kth SLIV, and time domain resources of the shared channel corresponding to the Kth to Nth SLIVs are continuous. It should be noted that if K-J = 1, there is an interval between the time domain resources of the shared channel corresponding to the Jth SLIV and the Kth SLIV, if K-J = 2X, time domain resources of the shared channel corresponding to the J+1th to J+Xth SLIVs are continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, time domain resources of the shared channel corresponding to the K-X+1th to K-1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Kth SLIV, and there is an interval between the time domain resources of the shared channel corresponding to the J+Xth SLIV and the K-X+1th SLIV. If K-J = 2X+1, time domain resources of the shared channel corresponding to the J+1th to J+X+1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, time domain resources of the shared channel corresponding to the K-X+1th to K-1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Kth SLIV, and there is an interval between the time domain resources of the shared channel corresponding to the J+X+1th SLIV and the K-X+1th SLIV. The meaning of the interval is the same as that of the above embodiments.

[0364] It should be noted that if the time slot offset value is used to indicate the time domain resource of the shared channel corresponding to the first SLIV in the N SLIVs, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the first SLIV is located and the first symbol of the time slot where the DCI is located. If the time slot offset value is used to indicate the time domain resource of the shared channel corresponding to the SLIV other than the first SLIV, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the SLIV is located and the first symbol of the time slot where the DCI is located, or the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the SLIV is located and the first symbol of the time slot where the shared channel corresponding to the SLIV before the SLIV is located, or the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the SLIV is located and the first symbol of the time slot corresponding to the time slot offset value associated with the SLIV before the SLIV.

[0365] The transceiver 1210 is further configured to send the time domain resource indication information to the terminal device.

[0366] Specifically, the time domain resource indication information can be carried in the DCI signaling.

[0367] Specifically, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, and the first table item includes first information, and the first information includes N SLIVs.

[0368] The transceiver 1210 is further configured to send the shared channel to the terminal device on the time domain resource of the shared channel.

[0369] Specifically, the transceiver 1210 sends the shared channel to the terminal device on the time domain resource of the downlink shared channel.

[0370] It should be noted that the apparatus can also perform the determination of the time domain resource of the uplink control channel corresponding to the uplink transmission, which is similar to the above description. The corresponding steps are briefly described below, and it should be understood that the corresponding contents in each step are similar to those of the downlink transmission, and the description of the above embodiments can be referred to.

[0374] The transceiver 1210 is further configured to receive information sent by the terminal device on the time domain resource of the uplink shared channel.

[0375] In some embodiments, the communication apparatus 1200 can be the terminal device in the method embodiment 500 above, or a chip for implementing the functions of the terminal device in the method embodiment above. It should be understood that the communication apparatus 1200 can correspond to the steps corresponding to the terminal device in the method 500 of the embodiments of the present application. The communication apparatus 1200 comprises:

[0376] The transceiver 1210 is configured to receive time domain resource configuration information sent by the network device.

[0377] The processing unit 1220 is configured to determine the time domain resource of the shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0378] Optionally, the time domain resource configuration information can be carried in RRC

[0379] Specifically, the time domain resource configuration information can include a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N SLIVs. Each SLIV is used to indicate the time domain resource of a shared channel in a slot. Specifically, each SLIV indicates the time domain resource of the shared channel corresponding to the SLIV in the slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the N shared channels corresponding to the N SLIVs in the slot.

[0380] Specifically, each of the N SLIVs included in the first information can be associated with a slot offset value, or can not be associated with a slot offset value. It should be understood that the association of the slot offset value of each of the N SLIVs can determine the distribution of the time domain resources of the N shared channels corresponding to the N SLIVs.

[0381] In some embodiments, the first information includes no time slot offset value associated with the N SLIVs, indicating that the time domain resources of the shared channel corresponding to the N SLIVs are continuous in time slots. Optionally, a time slot in which the time domain resources of the shared channel corresponding to a first SLIV of the N SLIVs are located is determined by a predefined time slot offset value. It should be understood that the continuity in time slots indicates that there is no interval between the time domain resources of the shared channel corresponding to any two adjacent SLIVs of the N SLIVs, and it is only required to arrange the time domain resources of the shared channel corresponding to the N SLIVs in sequence according to the symbols within the time slots indicated by the SLIVs. The meaning of the interval can be that the index difference between the time slot in which the time domain resources of the shared channel corresponding to a previous SLIV are located and the time slot in which the time domain resources of the shared channel corresponding to a subsequent SLIV are located is greater than 1.

[0382] In some embodiments, only one of the N SLIVs included in the first information is associated with a time slot offset value, indicating that the time domain resources of the shared channel corresponding to the N SLIVs are continuous in time slots, and the meaning of the continuity in time slots is similar to that of the above embodiments, which can be referred to the related description of the above embodiments. A time slot in which the time domain resources of the shared channel corresponding to a first SLIV of the N SLIVs are located is determined by the time slot offset value associated with the one SLIV.

[0383] In some embodiments, more than one of the N SLIVs included in the first information is associated with a respective time slot offset value, e.g., only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, indicating that time slots in which time domain resources of shared channels corresponding to the J+1th SLIV to the Kth SLIV are located are continuous, time slots in which time domain resources of shared channels corresponding to the Kth SLIV to the Nth SLIV (when N = K, the Kth SLIV to the Nth SLIV only contains one SLIV) are located are determined by the time slot offset value associated with the Kth SLIV, time domain resources of shared channels corresponding to the J+1th SLIV to the K-1th SLIV are located before and continuous with time domain resources of shared channels corresponding to the Kth SLIV, there is a gap between the Jth SLIV and the J+1th SLIV, time domain resources of shared channels corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, and time domain resources of shared channels corresponding to the 1st SLIV to the Jth SLIV are continuous. The meaning of the gap is the same as that of the above embodiments.

[0384] In some embodiments, more than one of the N SLIVs included in the first information is associated with a respective time slot offset value, e.g., only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, indicating that time slots in which time domain resources of shared channels corresponding to the J+1th SLIV to the Kth SLIV are located are continuous, time slots in which time domain resources of shared channels corresponding to the Kth SLIV to the Nth SLIV (when N = K, the Kth SLIV to the Nth SLIV only contains one SLIV) are located are determined by the time slot offset value associated with the Kth SLIV, time domain resources of shared channels corresponding to the J+1th SLIV to the K-1th SLIV are located before and continuous with time domain resources of shared channels corresponding to the Kth SLIV, there is a gap between the Jth SLIV and the J+1th SLIV, time domain resources of shared channels corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, and time domain resources of shared channels corresponding to the 1st SLIV to the Jth SLIV are continuous. The meaning of the gap is the same as that of the above embodiments.

[0385] In some embodiments, the first information comprises that more than one of the N SLIVs is associated with a respective time slot offset value, for example, only the Jth SLIV and the Kth SLIV of the N SLIVs are associated with a respective time slot offset value, K is greater than J, time domain resources of the shared channel corresponding to the 1th to Jth SLIVs are continuous, time domain resources of the shared channel corresponding to the Jth SLIV are determined by the time slot offset value associated with the Jth SLIV, time domain resources of the shared channel corresponding to the 1th to J-1th SLIVs are before and continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, time domain resources of the shared channel corresponding to the Kth SLIV are determined by the time slot offset value corresponding to the Kth SLIV, and time domain resources of the shared channel corresponding to the Kth to Nth SLIVs are continuous. It should be noted that if K-J = 1, there is an interval between the time domain resources of the shared channel corresponding to the Jth SLIV and the Kth SLIV, if K-J = 2X, the time domain resources of the shared channel corresponding to the J+1th to J+Xth SLIVs are continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, the time domain resources of the shared channel corresponding to the K-X+1th to K-1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Kth SLIV, and there is an interval between the time domain resources of the shared channel corresponding to the J+Xth SLIV and the K-X+1th SLIV. If K-J = 2X+1, the time domain resources of the shared channel corresponding to the J+1th to J+X+1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Jth SLIV, the time domain resources of the shared channel corresponding to the K-X+1th to K-1th SLIVs are continuous with the time domain resources of the shared channel corresponding to the Kth SLIV, and there is an interval between the time domain resources of the shared channel corresponding to the J+X+1th SLIV and the K-X+1th SLIV. The meaning of the interval is the same as that of the above embodiments.

[0386] It should be noted that if the time slot offset value is used to indicate the time domain resource of the shared channel corresponding to the first SLIV in the N SLIVs, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the first SLIV is located and the first symbol of the time slot where the DCI is located. If the time slot offset value is used to indicate the time domain resource of the shared channel corresponding to the SLIV other than the first SLIV, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the SLIV is located and the first symbol of the time slot where the DCI is located, or the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the SLIV is located and the first symbol of the time slot where the shared channel corresponding to the SLIV before the SLIV is located, or the number of time slots between the first symbol of the time slot where the time domain resource of the shared channel corresponding to the SLIV is located and the first symbol of the time slot corresponding to the time slot offset value associated with the SLIV before the SLIV.

[0387] The transceiver 1210 is further configured to receive the time domain resource indication information sent by the network device.

[0388] Specifically, the time domain resource indication information can be carried in DCI signaling.

[0389] Specifically, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, and the first table item includes first information, and the first information includes N SLIVs.

[0390] The transceiver 1210 is further configured to receive the shared channel sent by the network device on the time domain resource of the shared channel.

[0391] It should be noted that the apparatus can also perform determination of the time domain resource of the uplink control channel corresponding to the uplink transmission, which is similar to the above description. The corresponding steps are briefly described below, and it should be understood that the corresponding contents in each step are similar to those of the downlink transmission, and the description of the above embodiments can be referred to.

[0392] The transceiver 1210 is configured to receive the time domain resource configuration information sent by the network device.

[0393] The transceiver 1210 is further configured to receive the time domain resource indication information sent by the network device.

[0394] The processing unit 1220 is configured to determine the time domain resource of the uplink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0395] The transceiver 1210 is further configured to send the shared channel to the network device on the time domain resource of the uplink shared channel.

[0396] In some embodiments, the communication apparatus 1200 can be a network device in the above method embodiment 600, or a chip for implementing the functions of the network device in the above method embodiments. It should be understood that the communication apparatus 1200 can correspond to the steps corresponding to the network device in the method 600 of the embodiments of the present application. The communication apparatus 1200 comprises:

[0397] The transceiver unit 1210 is configured to send time domain resource configuration information to a terminal device.

[0398] The processing unit 1220 is configured to determine time domain resources of a shared channel according to the time domain resource configuration information and time domain resource indication information.

[0399] Optionally, the time domain resource configuration information can be carried in RRC signaling.

[0400] Specifically, the time domain resource configuration information can be a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes a first information and a second information.

[0401] Specifically, the first information includes N SLIVs. Each SLIV is used to indicate the time domain resources of a shared channel in a slot. Specifically, each SLIV indicates which symbols its corresponding shared channel resource is located in the slot, and N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the N SLIVs corresponding shared channels in the slot.

[0402] Specifically, the second information includes M slot offset values. There is a preset association relationship between the slot offset values of the N SLIVs corresponding shared channels and the M slot offset values.

[0403] In some embodiments, the preset association relationship is that the N SLIVs are divided into M groups, if N / M can be divided evenly, the number of SLIVs in each group is N / M, if N / M cannot be divided evenly and the remainder is X, the number of SLIVs in the first X groups is floor(N / M)+1 or (N-X) / M+1, and the number of SLIVs in the (X+1)th group and subsequent groups is floor(N / M) or (N-X) / M. floor(·) represents the floor of "·". The meaning of the interval is that the index difference between the first symbol of the time domain resource of the shared channel corresponding to the last SLIV of the previous group and the first symbol of the time domain resource of the shared channel corresponding to the first SLIV of the next group is greater than 1. The time domain resources of the shared channel corresponding to one or more SLIVs in each group do not have an interval, in other words, the time slots in which the time domain resources of the shared channel corresponding to the one or more SLIVs in each group are located are continuous (if multiple SLIVs can be distributed in the same time slot, the time slots in which the time domain resources of the shared channel corresponding to the one or more SLIVs in each group are located can also be the same or continuous). The time slot offset value of the time domain resource of the shared channel corresponding to the first SLIV in the Yth group corresponds to the Yth time slot offset value in the second message. M is a positive integer less than or equal to N, and Y is a positive integer greater than or equal to 1 and less than or equal to M.

[0404] By way of example and not limitation, when one time slot offset value is included in the second message, it indicates that the time domain resources of the shared channel corresponding to the N SLIVs included in the first message are continuous, wherein the time domain resource of the shared channel corresponding to the first SLIV is determined by the first time slot offset value. As shown in case 1, Figure 4 In this case, N is taken as 7.

[0405] By way of example and not limitation, when two time slot offset values are included in the second message, it indicates that the N SLIVs included in the first message are divided into two groups, and the time domain resources of the shared channel corresponding to the two groups of SLIVs have an interval, wherein it is assumed that the last SLIV in the first group of SLIVs is the Jth SLIV, and the first SLIV in the second group is the (J+1)th SLIV, in this case, J = ceil(N / 2), wherein ceil represents rounding up, that is, if N / 2 can be divided evenly, J = N / 2, if N / 2 cannot be divided evenly and the remainder is X, J = (N-X) / 2+1. As shown in case 2, Figure 7As shown in case 2, if N equals 7, J=4, J+1=5, it means that when two slot offset values are included in the second message, the first 4 SLIVs are the first group and the 5th to 7th SLIVs are the second group, wherein the first SLIV in the first group, i.e. the 1st SLIV in the N SLIVs, corresponds to the first slot offset value in the second message, and the time domain resource of the shared channel corresponding to the 1st SLIV is determined according to the first slot offset value, and the time domain resources of the shared channels corresponding to the 2nd to 4th SLIVs are continuous with the time domain resource of the shared channel corresponding to the 1st SLIV. The first SLIV in the second group, i.e. the 5th SLIV in the N SLIVs, corresponds to the second slot offset value in the second message, and the time domain resource of the shared channel corresponding to the 5th SLIV is determined according to the second slot offset value, and the time domain resources of the shared channels corresponding to the 6th to 7th SLIVs are continuous with the time domain resource of the shared channel corresponding to the 5th SLIV.

[0406] As an example but not limitation, when three slot offset values are included in the second message, it means that the N SLIVs included in the first message are divided into three groups, and there is an interval between the time domain resources of the shared channels corresponding to the three groups of SLIVs, as shown in Figure 7Case 3, where it is assumed that the last SLIV in the first group is the Jth SLIV, and the last SLIV in the second group is the Kth SLIV, where J = ceil(N / 3) and K = ceil((N-J) / 2) + J, where ceil(A / B) means rounding up, i.e., if the value inside can be divided by an integer, taking the integer quotient, if the value inside cannot be divided by an integer, taking the integer quotient of (A-C) / B + 1, C = A%B, i.e., the remainder of A divided by B. If N is equal to 7, J = 3, and K = 5, it means that when three time slot offset values are included in the second message, the first to third SLIVs are the first group, the fourth to fifth SLIVs are the second group, and the sixth to seventh SLIVs are the third group. Among them, the first SLIV in the first group, i.e., the first SLIV in the N SLIVs, corresponds to the first time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the first SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the second and third SLIVs are continuous with the time domain resource of the shared channel corresponding to the first SLIV. The first SLIV in the second group, i.e., the fourth SLIV in the N SLIVs, corresponds to the second time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the fourth SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the fifth SLIV are continuous with the time domain resource of the shared channel corresponding to the fourth SLIV. The first SLIV in the third group, i.e., the sixth SLIV in the N SLIVs, corresponds to the third time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the sixth SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the seventh SLIV are continuous with the time domain resource of the shared channel corresponding to the sixth SLIV.

[0407] It should be noted that in the above examples, the SLIVs written in the blocks indicate that there is a time domain resource of a shared channel corresponding to an SLIV at this position. The size of the block cannot represent the size of the time domain resource, and the size of the interval cannot represent the size of the time slot offset value. The values of the time slot offset values and the values of the SLIVs are determined in the above embodiments. This application does not limit this.

[0408] In some embodiments, the one second information includes M time slot offset values, and the first information includes N SLIVs. The number of N SLIVs and the pre-defined or time domain resource indication information indicate the rule, and the first to mth time slot offset values in the M time slot offset values are effective. Optionally, the second information can be configured for each first information, or one second information can be configured for all first information including the first information in the TDRA resource table.

[0409] By way of example, and not limitation, the pre-defined or pre-configured rule can be:

[0410] (a) When the number of SLIVs included in the first information is less than or equal to 2, the first of the M time slot offset values takes effect, the time domain resources corresponding to the SLIVs included in the first information are continuous, and the first of the M time slot offset values is used to determine the time domain resources of the shared channel corresponding to the first SLIV in the first information.

[0411] (b) When the number of SLIVs included in the first information is less than or equal to 4, the first two of the M time slot offset values take effect, there is an interval between the time domain resources of the shared channels corresponding to the SLIVs included in the first information, and the distribution of the time domain resources can be determined according to the preset grouping rule.

[0412] (c) When the number of SLIVs included in the first information is less than or equal to 8, the first three of the M time slot offset values take effect, there are two intervals between the time domain resources of the shared channels corresponding to the SLIVs included in the first information, and the distribution of the time domain resources can be determined according to the preset grouping rule.

[0413] It should be noted that if the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the first SLIV of the N SLIVs, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the first SLIV are located and the first symbol of the time slot where the DCI is located. If the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the SLIV other than the first SLIV, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot where the DCI is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot where the shared channel corresponding to the SLIV before the associated SLIV is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot corresponding to the time slot offset value associated with the SLIV before the associated SLIV.

[0414] The transceiver 1210 is further configured to send time domain resource indication information to a terminal device.

[0415] Specifically, the time domain resource indication information can be carried in DCI signaling.

[0416] Optionally, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, and the first table item includes a first information and a second information.

[0417] Optionally, the time domain resource indication information can be used to indicate a first table item in the time domain resource configuration information, the first table item including a first information. The time domain resource indication information can also be used to indicate a second information.

[0418] Specifically, the processing unit 1220 determines the time domain resource of the downlink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0419] The transceiver 1210 is further configured to send the shared channel to the terminal device on the time domain resource of the shared channel.

[0420] It should be noted that the apparatus can also perform the determination of the time domain resource of the uplink control channel corresponding to the uplink transmission, which is similar to the above description. The corresponding steps are briefly described below, and it should be understood that the corresponding content in each step is similar to that of the downlink transmission, and the description of the above embodiments can be referred to.

[0421] The transceiver 1210 is configured to send the time domain resource configuration information to the terminal device.

[0422] The transceiver 1210 is further configured to send the time domain resource indication information to the terminal device.

[0423] The processing unit 1220 is configured to determine the time domain resource of the uplink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0424] The transceiver 1210 is further configured to receive the shared channel sent by the terminal device on the time domain resource of the uplink shared channel.

[0425] In some embodiments, the communication apparatus 1200 can be a terminal device in the above method embodiment 600, or a chip for implementing the functions of the terminal device in the above method embodiment. It should be understood that the communication apparatus 1200 can correspond to the steps corresponding to the terminal device in the method 600 of the embodiments of the present application. The communication apparatus 1200 includes:

[0426] The transceiver 1210 is configured to receive the time domain resource configuration information sent by the network device.

[0427] The processing unit 1220 is configured to determine the time domain resource of the shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0428] Optionally, the time domain resource configuration information can be carried in RRC signaling.

[0429] Specifically, the time domain resource configuration information can be a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes a first information and a second information.

[0430] Specifically, the first information includes N SLIVs. Each SLIV is used to indicate the time domain resource of a shared channel in a slot. Specifically, each SLIV indicates which symbols the corresponding shared channel resource is located in the slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the shared channels corresponding to the N SLIVs in the slot.

[0431] Specifically, the second information includes M slot offset values. There is a preset association relationship between the slot offset values of the shared channels corresponding to the N SLIVs and the M slot offset values.

[0432] In some embodiments, the preset association relationship is that the N SLIVs are divided into M groups. If N / M can be divided, the number of SLIVs in each group is N / M. If N / M cannot be divided, and the remainder is X, the number of SLIVs in the first X groups is floor(N / M)+1 or (N-X) / M+1, and the number of SLIVs in the X+1 group and the groups after it is floor(N / M) or (N-X) / M. floor(·) represents the floor of "·". Wherein, there is a gap between the time domain resources of the shared channels corresponding to the SLIVs in each group. The meaning of the gap is that the index difference between the first symbol of the time slot where the time domain resource of the last SLIV of the previous group corresponds to and the first symbol of the time slot where the time domain resource of the first SLIV of the next group corresponds to is greater than 1. There is no gap between the time domain resources of the shared channels corresponding to the one or more SLIVs in each group, in other words, the time slots where the time domain resources of the shared channels corresponding to the one or more SLIVs in each group are continuous (if multiple SLIVs can be distributed in the same time slot, then the time slots where the time domain resources of the shared channels corresponding to the one or more SLIVs in each group can also be the same or continuous). Wherein, the slot offset value of the time domain resource of the shared channel corresponding to the first SLIV in the Yth group corresponds to the Yth slot offset value in the second message. M is a positive integer less than or equal to N, and Y is a positive integer greater than or equal to 1 and less than or equal to M.

[0433] As an example but not limitation, when the second message includes one slot offset value, it indicates that the time domain resources of the shared channels corresponding to the N SLIVs included in the first message are continuous, wherein the time domain resource of the shared channel corresponding to the first SLIV is determined by the first slot offset value. For example, Figure 7Case 1 shown, at this time, take N as 7.

[0434] As an example but not limitation, when two time slot offset values are included in the second message, it indicates that the N SLIVs included in the first message are divided into two groups, and there is a gap between the time domain resources of the shared channels corresponding to the two groups of SLIVs, wherein, assuming that the last SLIV in the first group of SLIVs is the Jth SLIV, and the first SLIV in the second group is the J+1th SLIV, at this time, J = ceil(N / 2), wherein ceil represents rounding up, that is, if N / 2 can be divided, J = N / 2, if N / 2 cannot be divided, and the remainder is X, then J = (N-X) / 2+1. As shown in Figure 7 Case 2, if N is equal to 7, J = 4, J+1 = 5, it indicates that when two time slot offset values are included in the second message, the first 4 SLIVs are the first group, and the 5th-7th SLIVs are the second group, wherein the first SLIV in the first group, that is, the first SLIV in the N SLIVs, corresponds to the first time slot offset value in the second message, and the time domain resources of the shared channel corresponding to the first SLIV are determined according to the time slot offset value, and the time domain resources of the shared channels corresponding to the 2nd-4th SLIVs are continuous with the time domain resources of the shared channel corresponding to the first SLIV. The first SLIV in the second group, that is, the 5th SLIV in the N SLIVs, corresponds to the second time slot offset value in the second message, and the time domain resources of the shared channel corresponding to the 5th SLIV are determined according to the time slot offset value, and the time domain resources of the shared channels corresponding to the 6th-7th SLIVs are continuous with the time domain resources of the shared channel corresponding to the 5th SLIV.

[0435] As an example but not limitation, when three time slot offset values are included in the second message, it indicates that the N SLIVs included in the first message are divided into three groups, and there is a gap between the time domain resources of the shared channels corresponding to the three groups of SLIVs, as shown in Figure 7Case 3, where it is assumed that the last SLIV in the first group is the Jth SLIV, and the last SLIV in the second group is the Kth SLIV, where J = ceil(N / 3) and K = ceil((N-J) / 2) + J, where ceil(A / B) means rounding up, i.e., if the value inside can be divided by an integer, taking the integer quotient, if the value inside cannot be divided by an integer, taking the integer quotient of (A-C) / B + 1, C = A%B, i.e., the remainder of A divided by B. If N is equal to 7, J = 3, and K = 5, it means that when three time slot offset values are included in the second message, the first to third SLIVs are the first group, the fourth to fifth SLIVs are the second group, and the sixth to seventh SLIVs are the third group. Among them, the first SLIV in the first group, i.e., the first SLIV in the N SLIVs, corresponds to the first time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the first SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the second and third SLIVs are continuous with the time domain resource of the shared channel corresponding to the first SLIV. The first SLIV in the second group, i.e., the fourth SLIV in the N SLIVs, corresponds to the second time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the fourth SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the fifth SLIV are continuous with the time domain resource of the shared channel corresponding to the fourth SLIV. The first SLIV in the third group, i.e., the sixth SLIV in the N SLIVs, corresponds to the third time slot offset value in the second message, and the time domain resource of the shared channel corresponding to the sixth SLIV is determined according to the time slot offset value. The time domain resources of the shared channels corresponding to the seventh SLIV are continuous with the time domain resource of the shared channel corresponding to the sixth SLIV.

[0436] It should be noted that in the above examples, the SLIVs in the blocks indicate that there is a time domain resource of a shared channel corresponding to an SLIV at this position. The size of the block cannot represent the size of the time domain resource, and the size of the interval cannot represent the size of the time slot offset value. The values of the time slot offset values and the values of the SLIVs are determined in the above embodiments. This application does not limit this.

[0437] In some embodiments, the one second information includes M time slot offset values, and the first information includes N SLIVs. The number of N SLIVs and the pre-defined or time domain resource indication information indicate the rule, and the first to mth time slot offset values in the M time slot offset values are effective. Optionally, the second information can be configured for each first information, or one second information can be configured for all first information including the first information in the TDRA resource table.

[0438] By way of example, and without limitation, the pre-defined or pre-configured rule can be:

[0439] (a) When the number of SLIVs included in the first information is less than or equal to 2, the first of the M time slot offset values takes effect, the time domain resources corresponding to the SLIVs included in the first information are continuous, and the first of the M time slot offset values is used to determine the time domain resources of the shared channel corresponding to the first SLIV in the first information.

[0440] (b) When the number of SLIVs included in the first information is less than or equal to 4, the first two of the M time slot offset values take effect, there is an interval between the time domain resources of the shared channels corresponding to the SLIVs included in the first information, and the distribution of the time domain resources can be determined according to the preset grouping rule.

[0441] (c) When the number of SLIVs included in the first information is less than or equal to 8, the first three of the M time slot offset values take effect, there are two intervals between the time domain resources of the shared channels corresponding to the SLIVs included in the first information, and the distribution of the time domain resources can be determined according to the preset grouping rule.

[0442] It should be noted that if the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the first SLIV of the N SLIVs, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the first SLIV are located and the first symbol of the time slot where the DCI is located. If the time slot offset value is used to indicate the time domain resources of the shared channel corresponding to the SLIV other than the first SLIV, the time slot offset value can indicate the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot where the DCI is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot where the shared channel corresponding to the SLIV before the associated SLIV is located, or the number of time slots between the first symbol of the time slot where the time domain resources of the shared channel corresponding to the associated SLIV are located and the first symbol of the time slot corresponding to the time slot offset value associated with the SLIV before the associated SLIV.

[0449] It should be noted that the device can also perform the determination of the time domain resources of the uplink control channel corresponding to the uplink transmission, similar to the above description. The corresponding steps are briefly described below. It should be understood that the content of each step is similar to that of the downlink transmission, and can be referred to the description of the above embodiments.

[0450] The transceiver unit 1210 is used to receive time-domain resource configuration information sent by network devices.

[0451] The transceiver unit 1210 is also used to receive time-domain resource indication information sent by network devices.

[0452] The processing unit 1220 is used to determine the time domain resources of the uplink shared channel based on the time domain resource configuration information and the time domain resource indication information.

[0453] The transceiver unit 1210 is also used to transmit the shared channel to the network device on the time domain resources of the uplink shared channel.

[0454] In some embodiments, the communication device 1200 may be a network device as described in the method embodiment 800 above, or it may be a chip used to implement the functions of the network device in the method embodiment above. It should be understood that the communication device 1200 may correspond to the steps of the network device in the method 800 of this application embodiment. The communication device 1200 includes:

[0456] Processing unit 1220: used to determine the time domain resources of the shared channel based on time domain resource configuration information and time domain resource indication information.

[0457] Optionally, this time-domain resource configuration information can be carried in RRC signaling.

[0458] Specifically, the time domain resource configuration information can include a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N SLIVs. Each SLIV is used to indicate the time domain resource of a shared channel in a slot. Specifically, each SLIV indicates the time domain resource of the shared channel corresponding to the SLIV in the slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the shared channels corresponding to the N SLIVs in the slot.

[0459] In some embodiments, the network device can predefine or configure a plurality of pattern sets, wherein each pattern set includes a plurality of patterns, and each pattern corresponds to a time domain resource distribution of a shared channel corresponding to a number of SLIVs, and different patterns correspond to different time domain resource distributions of shared channels corresponding to different numbers of SLIVs.

[0460] By way of example and without limitation, the plurality of pattern sets can be as shown in Figure 7 Figure 9 Each pattern in each pattern set shown in the above table corresponds to a time domain resource distribution of a shared channel corresponding to a number of SLIVs. Figure 9 Three pattern sets are shown, wherein Figure 9 (a) of the above table indicates that the time domain resources of the shared channels corresponding to the N SLIVs are continuous or do not exist. Figure 9 (b) of the above table indicates that there is at most one interval between the time domain resources of the shared channels corresponding to the N SLIVs, and the existence or nonexistence of the interval is determined by the number of SLIVs. Figure 9 (c) of the above table indicates that there are at most three intervals between the time domain resources of the shared channels corresponding to the N SLIVs, and the specific number of intervals is determined by the number of SLIVs. For example, when the pattern set shown in (c) of the above table corresponds, if the number of SLIVs is 7, it corresponds to the time domain resource distribution of the shared channel indicated by the seventh row of (c) of the above table. Figure 9 Figure 9 Figure 9 In the above table, the SLIV written in the block indicates that there is a time domain resource of a shared channel at this position, and the absence of SLIV in the block indicates that this position is an interval. The size of the block does not represent the size of the resource or the interval.

[0461] It should be noted that the distribution rule of the time domain resources of the shared channels corresponding to the SLIVs in the pre-defined or configured pattern set can be similar to the pre-set rule in method 600, or other distribution rules can be used. The pattern set mentioned in this embodiment is only an example, and the present application does not limit this.

[0462] ​​​It should be noted that which one of the pattern sets is indicated by the time domain resource indication information, or is default.

[0463] It should be noted that the existence interval indicates that the index difference between the time slot where the time domain resource of the shared channel corresponding to the previous SLIV is located and the time slot where the time domain resource of the shared channel corresponding to the subsequent SLIV is located is greater than 1. The specific difference of the interval can be default, or can be indicated by the time domain resource indication information.

[0464] The transceiver 1210 can also be configured to send the time domain resource indication information to the terminal device.

[0465] Specifically, the time domain resource indication information can be carried in DCI signaling.

[0466] Specifically, the time domain resource indication information can indicate a first table entry of the TDRA table. Optionally, the time domain resource indication information can also be used to indicate an interval value. Optionally, the time domain resource indication information can also be used to indicate a pattern set.

[0467] It should be noted that when the time domain resource indication information indicates a pattern set, it can be considered that when not indicated, a certain pattern set is default, which can save the signaling load of the network side.

[0468] It should be noted that the pattern set indicated by the time domain resource indication information can be one of the multiple pattern sets configured in the time domain configuration information, wherein the multiple pattern sets configured can not include the default pattern set.

[0469] Specifically, the processing unit 1220 determines the time domain resource of the uplink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0470] The transceiver 1210 is also configured to send the shared channel to the terminal device on the time domain resource of the shared channel.

[0471] It should be noted that the apparatus can also perform determination of the time domain resource of the uplink control channel corresponding to the uplink transmission, which is similar to the above description. The corresponding steps are briefly described below. It should be understood that the corresponding contents in each step are similar to those of the downlink transmission, and reference can be made to the description of the above embodiments.

[0473] The transceiver 1210 is also configured to send the time domain resource indication information to the terminal device.

[0474] The processing unit 1220 is configured to determine the time domain resource of the uplink shared channel according to the time domain resource configuration information and the time domain resource indication information.

[0475] The transceiver 1210 is further configured to receive the shared channel sent by the terminal device on the time domain resource of the uplink shared channel.

[0476] In some embodiments, the communication apparatus 1200 can be the terminal device in the method embodiment 800 above, or can be a chip for implementing the functions of the terminal device in the method embodiments above. It should be understood that the communication apparatus 1200 can correspond to the steps of the terminal device in the method 800 of the embodiments of the present application. The communication apparatus 1200 comprises:

[0479] Optionally, the time domain resource configuration information can be carried in RRC signaling.

[0480] Specifically, the time domain resource configuration information can include a TDRA table, and the TDRA table includes a plurality of table entries (which can be an item or a list). At least one first table entry includes first information. The first information includes N SLIVs. Each SLIV is used to indicate the time domain resource of a shared channel in a slot. Specifically, each SLIV indicates the time domain resource of the shared channel corresponding to the SLIV in the slot. N is a positive integer greater than 1. It should be understood that the arrangement order of the N SLIVs in the first information corresponds to the arrangement order of the time domain resources of the N shared channels corresponding to the N SLIVs in the slot.

[0481] In some embodiments, the network device can define or configure a plurality of pattern sets in advance, wherein each pattern set includes a plurality of patterns, and each pattern corresponds to the time domain resource distribution of a shared channel with a number of SLIVs. Different patterns correspond to different time domain resource distributions of shared channels with different numbers of SLIVs.

[0482] As an example but not limitation, the plurality of pattern sets can be as shown in Figure 9 Figure 9 Each pattern in each pattern set corresponds to the time domain resource distribution of a shared channel with a number of SLIVs. Figure 9 Three pattern sets are shown, wherein Figure 9 (a) of FIG. 8 shows that the time domain resources of the N shared channels corresponding to the N SLIVs are continuous or do not exist. Figure 9 ​(b) indicates that there is at most one gap between the time-domain resources of the shared channel corresponding to N SLIVs, and the presence or absence of a gap is determined by the number of SLIVs. Figure 9 (c) indicates that there are at most three gaps between the time-domain resources of the shared channel corresponding to N SLIVs, and the specific number of gaps is determined by the number of SLIVs. For example, when the pattern set indicated by (c) corresponds to Figure 9 (c) corresponds to, if the number of SLIVs is 7, the time-domain resource distribution of the shared channel indicated by the seventh row of (c) corresponds. Figure 9 (c) corresponds to, if the number of SLIVs is 7, the time-domain resource distribution of the shared channel indicated by the seventh row of (c) corresponds. Figure 9 In (c), the SLIV written in the block indicates that there is a time-domain resource of the shared channel at this position, and the block without writing SLIV indicates that it is a gap at this position. The size of the block does not represent the size of the resource or the gap.

[0483] It should be noted that the distribution of the time-domain resources of the shared channel corresponding to the SLIV in the predefined or configured pattern set can be similar to the preset rule in method 600, or other distribution rules can be used. The pattern set mentioned in the embodiment is only an example, and the present application does not limit it.

[0484] It should be noted that which pattern set to use can be indicated by the time-domain resource indication information, or it can be default.

[0485] It should be noted that the presence of the gap indicates that the index difference between the time slot where the time-domain resource of the shared channel corresponding to the previous SLIV is located and the time slot where the time-domain resource of the shared channel corresponding to the next SLIV is located is greater than 1. The specific difference of the gap can be default, or can be indicated by the time-domain resource indication information.

[0486] The transceiver unit 1210 is further configured to receive the time-domain resource indication information sent by the network device.

[0487] Specifically, the time-domain resource indication information can be carried in the DCI signaling.

[0488] Specifically, the time-domain resource indication information can indicate a first table entry of the TDRA table. Optionally, the time-domain resource indication information can also be used to indicate a gap value. Optionally, the time-domain resource indication information can also be used to indicate a pattern set.

[0489] It should be noted that when the time-domain resource indication information indicates a pattern set, it can be considered that when no indication is given, a certain pattern set is default, which can save the signaling load of the network side.

[0490] It should be noted that the one pattern set indicated by the time domain resource indication information can be one of the multiple pattern sets configured in the time domain configuration information, and the multiple pattern sets configured can not include the default pattern set.
