Description of Embodiments

[0070] The present application provides a communication method and a communication apparatus such that a network device configures, for different terminal devices, information S about the initial location of time domain symbols occupied by uplink data or downlink data, and information L about the number of time domain symbols occupied . The method and device are based on the same concept of the invention. The method and device have similar principles for solving the problem. Therefore, to implement the device and method, please contact each other. Repeated parts are not described.

[0071] The following clearly and completely describes the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of the present application.

[0072] As shown in FIG. 1, the present application provides a communication system 100. Communication system 100 includes a network device 101 and a terminal device 102.

[0073] The network device 101 is responsible for providing a radio access related service to the terminal device 102 and implements a radio physical layer function, a resource scheduling and radio resource control function, a quality of service (QoS) management function, a radio access control function, and a mobility management.

[0074] The terminal device 102 is a device that accesses the network through the network device 101.

[0075] The network device 101 and the terminal device 102 are connected using the Uu interface to realize communication between the terminal device 102 and the network device 101.

[0076] In this embodiment of the present application, the network device 101 may configure other time domain resource information for the terminal device 102 to perform uplink data transmission and downlink data transmission. In the example of the present application, the time domain resource information configured by the network device for the terminal device, see the following Table 1.

Table 1

index K0/K2 (beginning, length) Display type 0 0 *** *** **** … … … … n b *** *** ****

[0077] An index (index) is used to indicate the amount of time domain resource information configured by the network device 101 for the terminal device 102. For example, the maximum value of n may be 16, and this indicates that the network device 101 can configure a maximum of 16 time area for the terminal device 102.

[0078] It should be noted that the network device may alternatively configure each column in Table 1 in an enumeration manner. For example, a network device configures time domain resource information as follows:

K0/K2 = {k1, k2, k3,…, kn};

(beginning, length) = {s1, s2, s3,…, sn};

Mapping type = {..., Type j, ..., Type i, ...}, total n types.

[0079] K0 is used to indicate the initial location of the slot (slot) occupied by the physical downlink data channel (physical downlink shared channel, PDSCH) downlink data. K0 has four possible values and must be indicated by the network device 101 using 2-bit higher layer signaling, such as radio resource control (RRC) signaling.

[0080] K2 is used to indicate the initial location of a slot occupied by a physical uplink shared channel (PUSCH) of uplink data. K2 has eight possible values and must be indicated by the network device 101 using higher layer 3-bit signaling, such as RRC signaling.

[0081] In (start, length), "start" represents the starting location of time domain symbols that are occupied by uplink data or downlink data in one slot, and "length" represents the number of time domain symbols that are occupied by uplink data or downlink data in one slot. For ease of description, "start" may be represented as S, and "length" may be represented as L below.

[0082] A mapping type may be used to indicate a PDSCH mapping type, or may be used to indicate a PUSCH mapping type. In particular, there are two possible data mapping types in NR: type 1 and type 2. Type 1 represents that a demodulation reference signal (DMRS) is mapped to the first symbol in the scheduled uplink data channel resource or the first symbol in downlink data channel, and type 2 represents that DMRS is mapped to the third symbol or the fourth symbol of the slot. One bit may be used to configure the PDSCH mapping type.

[0083] Based on the above descriptions, the present application provides a communication method enabling a network device 101 to configure S and L information for a terminal device 102. For ease of understanding by a person skilled in the art, certain terms in this application are first explained. In details:

[0084] (1) A network device is a device that resides on a network and that connects a terminal device to a wireless network. A network device is a node in a radio access network and may also be referred to as a base station, or may be referred to as a node (or device) of a radio access network (RAN). Currently, the network device is, for example, gNB, transmission and reception point (TRP), advanced NodeB (evolved NodeB, eNB), radio network controller (RNC), NodeB (NodeB, NB), base station controller (BSC), base transceiver station (BTS), home NodeB (e.g., Home Enhanced NodeB or Home NodeB, HNB), base band unit (BBU), or access point (AP) wireless reliability (wireless fidelity, Wi-Fi). Further, in the network structure, the network device may include a centralized unit (CU) node and a distributed unit (DU) node. In this structure, the eNB protocol layer in the long term evolution (LTE) system is separated. Some protocol layer functions are centrally managed by the CU, the rest or all of the protocol layer functions are distributed to the DU, and the CU manages the DU in a centralized manner.

[0085] (2) A terminal device is also referred to as a user equipment (user equipment, UE), a mobile station (mobile station, MS), a mobile terminal (mobile terminal, MT) or the like, and is a device that enables voice transmission and/or data for the user, for example, a portable device or a device installed in a car that has a wireless connection function. Currently, the terminal is, for example, a mobile phone (mobile phone), a tablet computer, a laptop, a PDA, a mobile Internet device (MID), a wearable terminal, a virtual reality device (virtual reality, VR), an augmented augmented reality (AR), industrial control wireless terminal, self driving wireless terminal, remote medical surgery wireless terminal, smart grid wireless terminal , a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home.

The terms "system" and "network" can be used interchangeably. A CDMA system may implement radio technologies such as universal terrestrial radio access (UTRA) and CDMA 2000. UTRA may include wideband CDMA (WCDMA) technology and other variations of CDMA technology. CDMA 2000 may cover the interim standard (IS) 2000 (IS-2000), the IS-95 standard, and the IS-856 standard.

UTRA and E-UTRA are respectively UMTS and an advanced version of UMTS. A new version of UMTS, namely E-UTRA, is used in the long term evolution (long term evolution, LTE) of 3GPP, and various versions have evolved based on LTE. In addition, the communication system is further applicable to future-oriented communication technology. As long as the communication system using the new communication technology includes setting up a data link, the communication system is applicable to the technical solutions provided in the embodiments of the present application.

[0087] (4) The time domain symbol may include, but is not limited to, an orthogonal frequency division multiplexing (OFDM) symbol.

[0088] (5) "Set" means two or more, and other quantifiers are similar.

[0089] In addition, it should be understood that in the descriptions of this application, terms such as "first" and "second" are used only for the purpose of distinguishing descriptions, but they should not be understood as an indication or consequence of relative importance, and should not be understood as an indication or sequence consequence.

[0090] As shown in FIG. 2, the present application provides a communication method procedure. The network device in the procedure may correspond to the network device 101 in FIG. 1 and the terminal device may correspond to the terminal device 102 in FIG. 1. The method includes the following steps.

[0091] Step S201: The network device determines M pieces of first information.

[0092] In the present application, the first information includes an initial location S of time domain symbols occupied by uplink data or downlink data, and information L about the number of time domain symbols occupied. M, S and L are each an integer. The value of M may be, but is not limited to, 16. When the value of M is 16, this indicates that the network device indicates 16 pieces of S information and L information or 16 combinations of S and L for the terminal device; or when the value of M is 4, this indicates that the network device indicates four pieces of S information and L information or four combinations of S and L for the terminal device.

[0093] Step S202: The network device sends the first indication information.

[0094] The first information may be carried in higher layer signaling such as RRC signaling or MAC signaling, in which case the first information may also be referred to as configuration information. Alternatively, the first information may be carried in dynamic signaling such as the PDCCH.

[0095] In the present application, the first indication information includes M indication parameters, and each indication parameter is represented by seven bits. The M display parameters M correspond to the M pieces of the first information. Optionally, the M indication parameters are in one-to-one correspondence with the M pieces of first information, or the M indication parameters respectively correspond to the M pieces of first information.

[0096] In an implementation, the M indication parameters may be determined based on the M pieces of the first information.

[0097] In the example of the present application, the M indication parameters may be M indication values, or may be M indices. The M indication values may specifically be start and length indicator values (SLIV) or may be resource indication values (RIV). The M indices may be indices, and the index corresponds to the start and length index.

[0098] Step S203: The terminal apparatus may determine M pieces of first information based on the M indication parameters.

[0099] In this embodiment of the present application, the procedure shown in FIG. 2 is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 2 are M indication values.

[00100] First, the network device selects M pieces of first information from a set of first information.

[00101] In the present application, the first information set may include all combinations of S and L. In an exemplary implementation, one slot may include 14 time domain symbols: time domain symbol 0, time domain symbol 1, time domain symbol 2, ..., symbol 13 of the time domain. The value of S can be from 0 to 13, and the value of L can be from 1 to 14. There are 105 combinations of S and L in total. To get the S reference location, refer to the PDCCH start symbol for scheduling data, or refer to the slot boundary. For example, the value of S may be 0 and the value of L may be 2, which may indicate that uplink data or downlink data occupy two time domain symbols in one slot from the PDCCH start location for scheduling uplink data, or downlink data, or may indicate that uplink data or downlink data occupy two time domain symbols in one slot from slot time domain symbol 0.

[00102] Second, the network device generates M indication values based on the M pieces of the first information.

[00103] For each of the M pieces of the first information, if L in the first information satisfies that (L-1) is less than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(L-1) +S; or if L in the first information satisfies that (L-1) is greater than 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S). L is greater than 0 and less than or equal to (14-S) and S is greater than or equal to 0 and less than or equal to 13.

[00104] Third, the network device represents each of the M indication values using seven bits to obtain the first indication information.

[00105] In this embodiment of the present application, the procedure shown in FIG. 2 is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 2 are M indication values and M indication values are SLIV.

[00106] First, the network device selects M pieces of first information from a set of first information.

[00107] In the example of the present application, the value of M may be 16, and when the value of M is 16, this indicates that the network device indicates 16 pieces of first information for the terminal device.

[00108] In the present application, the first information set may also include all combinations of S and L, for example, one slot includes 14 time domain symbols, and the first information set may include 105 combinations of S and L.

[00109] Second, the network device jointly encodes S and L in each of the M pieces of first information to obtain the SLIV corresponding to each piece of first information.

[00110] In the present application, for the S and L joint encoding formula to obtain the SLIV corresponding to each part of the first information, refer to the following formula (1.1):

[00111] In the example of the present application, when the value of S is in the range of 0 to 13 and the value of L is in the range of 1 to 14, the formula (1.1) calculation method is used. For the correspondence between (S, L) and SLIV, refer to the following table 2.

[00112] Third, the SLIV corresponding to each piece of the first information is represented by seven bits.

[00113] In this embodiment of the present application, for example, 000 000 0 is used to represent SLIV=0 in Table 2 and 000 001 0 is used to represent SLIV=2 in Table 2.

[00114] It can be learned from the above notation that if the value of S is in the range of 0 to 13 and the value of L is in the range of 1 to 14, then there are a total of 105 combinations of S and L, and seven bits can represent only 2⁷=128 binary data. For data 105 to 127, the network device can use the following two processing methods. In the first processing method, according to the predefined rule, the network device does not configure data 105 to 127 for the terminal device. In the second processing method, the network device may configure data 105 to 127 for the terminal device, and data 105 to 127 is used to indicate a default value according to the protocol specification, for example, S uplink data or downlink data corresponding to the value the default value is 0, and the L uplink data or downlink data corresponding to the default value is 14.

[00115] In this embodiment of the present application, the correspondence between (S, L) and SLIV can be obtained based on formula (1.1), and the network device can indicate SLIV using seven bits. Thus, the network device can flexibly configure all combinations of S and L for the terminal device. In addition, consecutive SLIVs can also be obtained using formula (1.1). Compared with the problem of the prior art that SLIVs are not sequential, in this embodiment, persistent information for a network device and a terminal device can be provided, and data transmission reliability is guaranteed.

[00116] In another example in the present application, the process in the present application is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 2 are M indices.

[00117] First, the network device selects M pieces of first information from a set of first information.

[00118] Second, the network device generates M indication values based on the M pieces of the first information.

[00119] For each of the M pieces of first information, the M indication values may be generated in any of the following two ways.

[00120] In the first method, if L in the first information satisfies that (L-1) is less than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(L-1)+S; or if L in the first information satisfies that (L-1) is greater than 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S).

[00121] In the second method, if L in the first information satisfies that (L-1) is less than 7, the network device determines that the indication value corresponding to the first information is 14×(L-1)+S; or if L in the first information satisfies that (L-1) is greater than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S) .

[00122] In the first and second methods, L is greater than 0 and less than or equal to (14-S) and S is greater than or equal to 0 and less than or equal to 13.

[00123] Third, the network device determines the M indices based on the M indication values.

[00124] In the example of the present application, the network device may predetermine the correspondence between the indication value and the index. Compliance may be indicated in the protocol. The network device may determine based on the correspondence of the M indexes corresponding to the M indication values. The protocol-specified correspondence between the indication value and the index is described in detail below.

[00125] In the present application, M indices are in a subset of X indices, and M indication values are in a subset of X indication values. X indices correspond to X display values. Optionally, the X indices are in a one-to-one correspondence with the X indication values, or the X indices respectively correspond to the X indication values. The X values of the indexes are different from the values corresponding to the same index, and X is a positive integer.

[00126] Fourth, the network device represents each of the M indices using seven bits to obtain the first indication information.

[00127] In another example in the present application, the process in the present application is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 2 are M indices, there is a correspondence between M indication parameters and M SLIV, and there is a correspondence between M SLIV and M indices.

[00128] First, the network device determines the SLIV value corresponding to each piece of first information in the first information set.

[00129] In the example of the present application, the network device can obtain based on the formula (1.1) SLIV corresponding to each part of the first information.

[00130] In the example of the present application, the network device can obtain, based on the formula (1.2), the SLIV corresponding to each piece of the first information, and the process is as follows:

[00131] The network device co-codes (S, L) in each piece of first information using formula (1.2) to obtain the SLIV corresponding to each piece of first information.

[00132] Second, the network device may map the SLIV value to the index according to one of the following rules.

[00133] 1. Sort SLIV in ascending order (or descending order) L:

for the same L, sort SLIV in ascending order of S;

for the same L, sort SLIV in descending order of S;

for the same L, sort SLIV in ascending order of SLIV; or

for the same L, sort SLIV in descending order of SLIV.

[00134] For sorted SLIVs, an index is sequentially added to each SLIV value in top-to-bottom order.

[00135] In the example of the present application, when SLIVs are sorted in ascending order of L, and for the same L, SLIVs are sorted in ascending order of S, and neighboring SLIV values incrementally increase by 1 from index 0, a correspondence between SLIV and index (index ) and the correspondence between the first information and the SLIV value can be shown in Table 3.

[00136] 2. Sort SLIV in ascending order (or descending order) S:

for the same S, sort SLIV in ascending order of L;

for the same S, sort SLIV in descending order of L;

for the same S, sort SLIV in ascending order of SLIV; or

for the same S sort SLIV in descending order of SLIV.

[00137] For sorted SLIVs, an index is sequentially added to each SLIV value in top-to-bottom order.

[00138] Third, the network device selects M pieces of first information from a set of first information.

[00139] Fourth, the network device determines, based on the correspondence between the first information and the SLIV in the above correspondences, the SLIV corresponding to each of the M pieces of the first information.

[00140] Fifth, the network device determines, based on the correspondence between the SLIV and the index in the above correspondences, an index corresponding to each of the M SLIVs.

[00141] Sixth, the network device uses seven bits to represent each of the M indices.

[00142] In this embodiment of the present application, compared with the calculation of the correspondence between (S, L) and SLIV using formula (1.2), when the correspondence between (S, L) and SLIV is calculated using formula (1.1), can be provided consecutive SLIVs. In addition, when there are 105 pieces of first information in total, regardless of whether formula (1.1) or formula (1.2) is used, each piece of first information can be represented using seven bits, and the network device can indicate all combinations of (S, L ), thereby realizing flexible data scheduling. The mapping between seven bits and SLIV is also negotiated, which provides constant information for the base station and user and ensures reliable data transmission.

[00143] As shown in FIG. 3, the present application provides a communication method procedure. The network device in the procedure may correspond to the network device 101 in FIG. 1, and the terminal device may correspond to the terminal device 102 in the above procedure. The method includes the following steps.

[00144] Step S301: The network device determines M pieces of first information.

[00145] In this embodiment of the present application, the network device first determines N pieces of first information, where N is an integer less than or equal to 64; and then selects M pieces of first information from N pieces of first information, where N pieces of first information are in a subset of the first information set, M pieces of first information are in a subset of N pieces of first information, each piece of first information includes information S about the initial position of symbols time domain occupied by uplink data or downlink data, and information L on the number of occupied time domain symbols, and the first information may also be referred to as configuration information, a combination of S and L, or the like.

[00146] In this embodiment of the present application, the network device may determine N pieces of the first information in multiple implementations. In the first implementation, the network device may select N pieces of first information from a set of first information in accordance with the protocol specification. For example, if only first information with L equal to 1, 2, 4, 7, and 14 is supported according to the protocol specification, the network device can select first information with L equal to 1, 2, 4, 7, and 14 from the set of first information to form N parts of the first information. In another example, if only the first information with L equal to 2, 4, 7 and 14 is supported in accordance with the protocol specification, the network device may select the first information with L equal to 2, 4, 7 and 14 from the set of first information for forming N parts of the first information. In the second implementation, the N pieces of the first information may be directly specified by the protocol. For example, a table of N pieces of first information is directly provided, where the values of L in the N pieces of first information may include 1, 2, 4, 7, and 14, and for another example, the values of L in the N pieces of first information may include 2, 4, 7 and 14. The network device determines the N pieces of the first information according to the protocol specification. In a third implementation, the network device selects N pieces of first information from a set of first information to determine N pieces of first information.

[00147] In this embodiment of the present application, when the implementation for determining the N pieces of the first information by the network device is the first or second implementation, the values of L in the N pieces of the first information finally determined by the network device may include one or more of the values of 1-14, and one or more of the values includes at least one of 1, 2, 4, 7, and 14. For example, the L values in the N parts of the first information selected by the network device may include 1, 2, 4, 6, 7, etc. An implementation falls within the scope of this application provided that the values of L in the N parts of the first information include at least one of 1, 2, 4, 7, and 14, and N is less than or equal to 64. When an implementation for determining the N parts of the first information via a network device is the third implementation, the values of L in the N parts of the first information are not limited and fall under the protection scope of the present application, provided that N is less than or equal to 64.

[00148] Step S302: The network device sends the first indication information.

[00149] The first information may be carried in higher layer signaling such as RRC signaling or MAC signaling, in which case the first information may also be referred to as configuration information. Alternatively, the first information may be carried in dynamic signaling such as the PDCCH.

[00150] In the present application, the first indication information includes M indication parameters, each indication parameter is represented by six bits, and the M indication parameters correspond to M pieces of the first information. Optionally, the M indication parameters are in one-to-one correspondence with the M pieces of first information, or the M indication parameters respectively correspond to the M pieces of first information.

[00151] In an implementation, M indication parameters are determined based on M pieces of first information.

[00152] In the example of the present application, the M indication parameters may be M indication values, or may be M indices. The M indication values may specifically be start and length indicator values (SLIV) or may be resource indication values (RIV). The M indices may be indices, and the index corresponds to the start and length index.

[00153] Optionally, after or before step S302, when the implementation for determining the N pieces of the first information by the network device is the third implementation, the method may further include the following: Step S303: the network device sends the second indication information, where the second indication information may be RRC signaling, and the second indication information is used to indicate the L values included in the N pieces of the first information. The second indication information may be represented by Y bits, each of the Y bits is used to indicate whether a corresponding L value exists in the first information, and Y is a positive integer. For example, when one slot includes 14 OFDM symbols, the second indication information may be represented by a bitmap of 14 bits, the value of the first bit in 14 bits is used to indicate whether the N pieces of the first information Y=1, the value of the second bit in 14 bits is used to indicate whether the N parts of the first information Y=2, and so on. If the bit is 1, this means that there is a corresponding L in the N parts of the first information, and if the bit is 0, it means that there are no corresponding Ls in the N parts of the first information. For example, a 14-bit bitmap might be 000,000,000,000 11, and it indicates that L supported in the protocol is 1 and 2, or the N pieces of the first information include L=1 and L=2. Alternatively, if the bit is 0, this indicates that there is a corresponding L in the N parts of the first information, and if the bit is 1, this indicates that there is no corresponding L in the N parts of the first information. For example, a 14-bit bitmap may be 000 000 000 000 11 and indicates that the N pieces of first information do not include L=1 or L=2, but include L=3 to 14.

[00154] Step S304: The terminal apparatus determines M pieces of first information based on the M indication parameters.

[00155] In this embodiment of the present application, the procedure shown in FIG. 3 will be described in detail using an example in which the M display parameters in the above procedure shown in FIG. 3 are M indication values.

[00156] First, the network device determines N pieces of first information.

[00157] To learn how to determine the N pieces of the first information, refer to the previous descriptions of the procedure shown in FIG. 3. Details are not described here again.

[00158] Second, the network device selects M pieces of first information from N pieces of first information.

[00159] Third, the network device generates M indication values based on the M pieces of the first information.

[00160] For each of the M pieces of the first information, if L in the first information satisfies that (L-1) is less than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(L-1) +S; or if L in the first information satisfies that (L-1) is greater than 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S). L is greater than 0 and less than or equal to (14-S) and S is greater than or equal to 0 and less than or equal to 13.

[00161] Fourth, the network device uses six bits to represent each of the M indication values to obtain the first indication information.

[00162] It should be noted that since the network device selects M pieces of first information from N pieces of first information, and each indication value is directly represented by six bits, the value of the indication value may be greater than 64, in which case the indication value cannot be directly represented by six bits. When the network device is an intelligent network device, and the indication values of the N pieces of the first information are definitely within 64, this solution can be used.

[00163] In this embodiment of the present application, the process in the present application is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 3 are M indices, there is a correspondence between M indication parameters and M SLIV, and there is a correspondence between M SLIV and M indices.

[00164] First, the network device determines N pieces of first information.

[00165] To learn how to determine the N pieces of the first information, refer to the previous descriptions of the procedure shown in FIG. 3. Details are not described here again.

[00166] Second, the network device selects M pieces of first information from N pieces of first information.

[00167] For example, when the value of M is 16, this indicates that the network device selects 16 pieces of first information from N pieces of first information.

[00168] Third, the network device generates M indication values based on the M pieces of the first information.

[00169] For each of the M pieces of first information, the M indication values may be generated in any of the following two ways.

[00170] In the first method, if L in the first information satisfies that (L-1) is less than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(L-1)+S; or if L in the first information satisfies that (L-1) is greater than 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S).

[00171] In the second method, if L in the first information satisfies that (L-1) is less than 7, the network device determines that the indication value corresponding to the first information is 14×(L-1)+S; or if L in the first information satisfies that (L-1) is greater than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S) .

[00172] In the first and second methods, L is greater than 0 and less than or equal to (14-S), and S is greater than or equal to 0 and less than or equal to 13.

[00173] Fourth, the network device determines the M indices based on the M indication values.

[00174] In the example of the present application, the network device may predetermine the correspondence between the indication value and the index. Compliance may be indicated in the protocol. The network device may determine based on the correspondence of the M indexes corresponding to the M indication values. The protocol-specified correspondence between the indication value and the index is described in detail below.

[00175] In the present application, M indices are in a subset of X indices, and M indication values are in a subset of X indication values. The X indices are in one-to-one correspondence with the X indication values. The X values of the indexes are different from the value corresponding to one index, and X is a positive integer.

[00176] Fifth, the network device represents each of the M indices using six bits to obtain the first indication information.

[00177] In another example in the present application, the process in the present application is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 3 are M indices, there is a correspondence between M indication parameters and M SLIV, and there is a correspondence between M SLIV and M indices.

[00178] First, the network device selects N pieces of first information from a set of first information.

[00179] To learn how to determine the N pieces of the first information, refer to the previous descriptions of the procedure shown in FIG. 3. Details are not described here again.

[00180] Second, the network device determines the SLIV corresponding to each of the N pieces of the first information.

[00181] In the example of the present application, the network device can obtain based on formula (1.1) or formula (1.2) SLIV corresponding to each of the N parts of the first information.

[00182] Third, the network device may map the SLIV and the index according to one of the following rules.

[00183] 1. Sort SLIV in ascending order (or descending order) L:

for the same L, sort SLIV in ascending order of S;

for the same L, sort SLIV in descending order of S;

for the same L, sort SLIV in ascending order of SLIV; or

for the same L, sort SLIV in descending order of SLIV.

[00184] For sorted SLIVs, the index is sequentially added to each SLIV in top-to-bottom order.

[00185] In the example of the present application, when the first information with L=1, 2, 4, 7 and 14 is specified in the protocol, SLIVs are sorted in ascending order of L, and for the same L, SLIVs are sorted in ascending order of S, and neighboring SLIVs are gradually increase by 1 compared to index 0, the formed correspondence between SLIV and index (index) can be shown in the following table 4.

Table 4

Index Length Start SLIV 0 one 0 0 one one one one 2 one 2 2 3 one 3 3 four one four four 5 one 5 5 6 one 6 6 7 one 7 7 eight one eight eight 9 one 9 9 ten one ten ten eleven one eleven eleven 12 one 12 12 13 one 13 13 fourteen 2 0 fourteen fifteen 2 one fifteen 16 2 2 16 17 2 3 17 eighteen 2 four eighteen 19 2 5 19 twenty 2 6 twenty 21 2 7 21 22 2 eight 22 23 2 9 23 24 2 ten 24 25 2 eleven 25 26 2 12 26 27 four 0 42 28 four one 43 29 four 2 44 thirty four 3 45 31 four four 46 32 four 5 47 33 four 6 48 34 four 7 49 35 four eight fifty 36 four 9 51 37 four ten 52 38 7 0 84 39 7 one 85 40 7 2 86 41 7 3 87 42 7 four 88 43 7 5 89 44 7 6 90 45 7 7 91 46 fourteen 0 27

[00186] Fourth, the network device selects M pieces of first information from N pieces of first information.

[00187] In this embodiment of the present application, the value of M may be 16, and when the value of M is 16, it indicates that the network device configures 16 pieces of first information for the terminal device.

[00188] Fifth, the network device determines, based on the correspondence between the first information and SLIV in the above SLIV correspondences, corresponding to each of the M pieces of the first information.

[00189] Sixth, the network device determines, based on the correspondence between the SLIV and the index in the above correspondences, an index corresponding to each of the M SLIVs.

[00190] Seventh, the network device uses six bits to represent each of the M indices.

[00191] In this embodiment of the present application, the values of the six bits are in one-to-one correspondence with the indices. For example, 000000 is used to match index 0 and 000010 is used to match index 2.

[00192] Eighth, when the method of determining N pieces of first information by the network device is the third implementation, the network device represents, using a Y-bit bitmap, L supported in the protocol, or represents the length of L in N pieces of first information using a bitmap. maps of Y bits.

[00193] In the example of the present application, when one slot includes 14 time domain symbols, a network device can represent, using a 14-bit bitmap, L supported in the protocol. For example, if the L supported by the protocol specification is 2, 7, and 14, the 14-bit bitmap could be 00100, 001000010, or could be 11011110111101.

[00194] For example, in the example of the present application, when L supported according to the protocol specification is 2, 7, and 14, for the corresponding index corresponding to SLIV and the correspondence between SLIV and the first information, refer to the following Table 5.

Table 5

Index Length Start SLIV 0 2 0 fourteen one 2 one fifteen 2 2 2 16 3 2 3 17 four 2 four eighteen 5 2 5 19 6 2 6 twenty 7 2 7 21 eight 2 eight 22 9 2 9 23 ten 2 ten 24 eleven 2 eleven 25 12 2 12 26 13 7 0 84 fourteen 7 one 85 fifteen 7 2 86 16 7 3 87 17 7 four 88 eighteen 7 5 89 19 7 6 90 twenty 7 7 91 21 fourteen 0 27

[00195] From the above descriptions, it can be learned that in this embodiment of the present application, the network device and the terminal device can obtain a correspondence between (S, L) and SLIV based on formula (1.1) or formula (1.2), and the network device can indicate the value SLIV of the selected data length using six bits. Thus, the number of bits in the signaling configuration can be reduced, and the protocol-specified combination (S, L) can be specified to realize flexible data scheduling, provide constant information to the network device and the terminal device, and enable data transmission.

[00196] It should be noted that in this embodiment of the present application, a bitmap can be used to represent L supported according to the protocol specification, and a bitmap can also be used to represent S supported according to the protocol specification. For example, if the protocol specification only supports time domain symbols S=0 to 7, a 14-bit bitmap could be 00000011111111 or 11111100000000.

[00197] It can be seen from Table 3 above that there are a maximum of 47 pieces of first information (specifically 0 to 46) in which L is 1, 2, 4, 7 and 14 according to the protocol specification, but 6-bit binary data can represent a maximum of 2 ⁶ =64 pieces of data. Therefore, the following two processing methods can be used for data 47 to 63: the first method indicates that the network device does not configure data 47 to 63 for the terminal device; and the second method indicates that when the network device configures data 47 to 63 for the terminal device, data 47 to 63 is the default value, for example, the default value may correspond to the initial location of S=0 and L=14, which are specified by the protocol .

[00198] The present application provides a communication method. The network device in the method may correspond to network device 101 in FIG. 1 and the method includes the following steps.

.[00199] The network device determines M pieces of first information, where M_i parts of the first information in the M pieces of first information are in a subset of the i-th set of first information, the i-th a set of first information represents is the i-th set of first information in the P sets of first information, the number of pieces of the first information included in each of the P sets of first information is less than or equal to 64, the first information includes information S about the initial location of the time domain symbols occupied by the uplink data or downlink data, and information L about the number of time domain symbols occupied, each of S, L, M, i, and P is an integer, i≤P, and

In the example of the present application, P is preset, and P=2.

[00205] The present application provides a communication method. The terminal device in the method may correspond to the terminal device 102 in the above procedure, and the method includes the following steps.

[00206] The terminal device receives the first indication information, where the first indication information includes M indication parameters, and each indication parameter is represented by six bits.

.[00207] The terminal device determines M pieces of first information, where M_i parts of the first information in M parts of the first information are in one-to-one correspondence with M_i display parameters in M display parameters, a M_i parts of the first information in M parts of the first information are in a subset of the i-th set of first information, the i-th set of first information represents i-th set first information in P sets of the first information, the number of first information pieces included in each of the P sets of first information is less than or equal to 64, the first information includes information S about the initial location of the time domain symbols occupied by the uplink data or the downlink data, and information L about the number of time domain symbols occupied, each of S, L, M, i, and P is an integer, i≤ P, and

[00208] In the example of the present application, the L values corresponding to the first information included in at least one of the P sets of first information include one or more values from 1-14, and the one or more values include at least one from 1, 2, 4, 7 and 14.

if (L-1) is less than or equal to 7, the indication value corresponding to the first information is 14×(L-1)+S; or if (L-1) is greater than 7, the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S), where L is greater than 0 and less than or equal to (14-S), and S is greater than or equal to 0 and less than or equal to 13.

[00212] In the example of the present application, P is predefined, and P=2.

[00213] As shown in FIG. 5, the present application provides a communication method procedure. The network device in the procedure may correspond to the network device 101 in FIG. 1, and the terminal device may correspond to the terminal device 102 in the above procedure. The method includes the following steps.

[00214] Step S501: The network device determines M pieces of first information.

[00215] In this embodiment of the present application, the network device first determines P sets of first information, where the number of first information pieces in each of the P sets of first information is less than or equal to 64; and then chooses M_i parts of the first information from the i-th set of first information in P sets of first information, where M_i parts of the first information are in a subset of the i-th set of first information, and each part The first information includes information S about the initial location of the time domain symbols occupied by uplink data or downlink data and information L about the number of occupied time domain symbols, or the first information is a combination of S and L, or the like.

[00216] In this embodiment of the present application, in implementation, P sets of first information may be defined by the protocol, and each set of first information includes a maximum of 64 pieces of first information. For example, P=2 sets of first information are defined by the protocol, and every two sets of first information are not exactly the same.

[00217] In this embodiment of the present application, the values of L in the first information in each set of first information are not limited and fall within the scope of this application provided that N is less than or equal to 64. In an implementation of the values of L in at least one of the P sets the first information may include 1, 2, 4, 7, and 14, and for another example, the L values in the N pieces of the first information may include 2, 4, 7, and 14.

[00218] Step S502: The network device sends the first indication information.

[00219] The first information may be carried in higher layer signaling, such as RRC signaling or MAC signaling, in which case the first information may also be referred to as configuration information. In addition, the first information may be carried in dynamic signaling such as PDCCH.

[00220] In the present application, the first indication information includes M indication parameters, each indication parameter is represented by six bits, and the M _i indication parameters in the M indication parameters are in one-to-one correspondence with the M _i first information parts in the M first information parts .

[00221] In an implementation, M indication parameters are determined based on M pieces of first information.

[00222] In the example of the present application, the M indication parameters may be M indication values, or may be M indices. M M indication values may specifically be start and length indicator values (SLIV) or may be resource indication values (RIV). The M indices may be indices, and the index corresponds to the start and length index.

[00223] Step S503: The terminal apparatus determines M pieces of first information based on the M indication parameters.

[00224] In this embodiment of the present application, the procedure shown in FIG. 5 is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 5 are M indication values.

[00225] First, the network device determines P sets of first information.

[00226] The P first information sets may be protocol-defined first information sets, and the details are not described here. For example, P=2 sets of first information may be defined by the protocol.

[00227] Second, the network device selects M pieces of the first information.

[00228] The network device selects M_i parts of the first information from the i-th set of information in P sets of first information, thereby selecting M pieces of first information in total. For example, the network device selects M_one pieces of first information from the first set of first information in two sets of first information and selects M₂ parts of the first information from the 2nd set of first information, thereby choosing M_one+M₂=M pieces of first information in total.

[00229] Third, the network device generates M indication values based on the M pieces of the first information.

[00230] The network device accordingly generates M_i display values for M_i parts of the first information, thereby generating M indication values in total. For example, a network device forms M_one display values for M_one parts of the first information and forms M₂display values for M₂ parts of the first information.

[00231] It is assumed that M=16. Thus, M ₁₌ 8, and M ₂ =8 _.

[00232] For each of the M _i pieces of the first information, if L in the first information satisfies that (L-1) is less than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(L-1 )+S; or if L in the first information satisfies that (L-1) is greater than 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S). L is greater than 0 and less than or equal to (14-S), and S is greater than or equal to 0 and less than or equal to 13.

[00233] Fourth, the network device represents each of the M indication values using six bits to obtain the first indication information.

[00234] It should be noted that since the network device selects M pieces of first information from P sets of first information, and each indication value is directly represented using six bits, the indication value value may be greater than 64, in which case the indication value cannot be directly represented using six bits. When the network device is an intelligent network device, and the indication value of the first information in each set of the first information is definitely within 64, this solution can be used.

[00235] In this embodiment of the present application, the process in this application is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 5 are M indices, there is a correspondence between M indication parameters and M SLIV, and there is a correspondence between M SLIV and M indices.

[00236] First, the network device determines P sets of first information.

[00237] In this embodiment of the present application, P sets of first information may be defined by a protocol, and each set of first information includes a maximum of 64 pieces of first information. For example, P=2 sets of first information are defined by the protocol, and the values of L in at least one of the P sets of first information may include 1, 2, 4, 7, and 14, and for another example, the values of L in at least one of The P sets of first information may include 2, 4, 7, and 14.

[00238] In this embodiment of the present application, the values of L in each of the P first information sets are not limited and fall within the scope of the present application provided that the number of first information pieces in each of the P first information sets is less than or equal to 64.

[00239] Second, the network device selects M pieces of the first information.

[00240] The network device selects M_iparts of the first information from the i-th set of information in P sets of first information, thereby selecting M pieces of first information in total. For example, the network device selects M_one pieces of first information from the first set of first information in two sets of first information and chooses M₂ parts of the first information from the 2nd set of the first information, thereby choosing M_one+M₂=M pieces of first information in total.

[00241] Third, the network device generates M indication values based on the M pieces of the first information.

[00242] The network device accordingly generates M_i display values for M_i parts of the first information, thereby generating M indication values in total. For example, a network device forms M_one display values for M_one parts of the first information and forms M₂ display values for M₂ parts of the first information.

[00243] It is assumed that M=16. Thus, M ₁ =8, and M ₂ =8.

[00244] For each of the M _i pieces of the first information, the M indication values may be generated in any of the following two ways.

[00245] In the first method, if L in the first information satisfies that (L-1) is less than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(L-1)S; or if L in the first information corresponds to (L-1) being greater than 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S).

[00246] In the second method, if L in the first information satisfies that (L-1) is less than 7, the network device determines that the indication value corresponding to the first information is 14×(L-1)+S; or if L in the first information satisfies that (L-1) is greater than or equal to 7, the network device determines that the indication value corresponding to the first information is 14×(14-L+1)+(14-1-S) .

[00247] In the first and second methods, L is greater than 0 and less than or equal to (14-S), and S is greater than or equal to 0 and less than or equal to 13.

[00248] Fourth, the network device determines the M indices based on the M indication values.

[00249] In the example of the present application, the network device may pre-determine the correspondence between M_i display values and M_i indexes. The correspondence may be determined by the protocol. The network device may determine, based on the match, M_i indices, corresponding M_i indication values. The following describes in detail the correspondence between the indication value and the index defined by the protocol.

[00250] In this application, M_iindices are in a subset of X indices, and M_i values indications are in a subset of X indication values. The X indices are in one-to-one correspondence with the X indication values. The X index values are different from the value corresponding to a single index value, and X is a positive integer.

[00251] Fifth, the network device represents each of the M indices using six bits to obtain the first indication information.

[00252] In another example of the present application, the process in this application is described in detail using an example in which the M display parameters in the above procedure shown in FIG. 5 are M indices, there is a correspondence between M indication parameters and M SLIV, and there is a correspondence between M SLIV and M indices.

[00253] First, the network device determines P sets of first information.

[00254] For the process in which the network device determines P sets of first information, refer to the descriptions of the above procedure. Details are not described here again.

[00255] Second, the network device determines the SLIV value corresponding to each piece of first information in each of the P sets of first information.

[00256] In the example of the present application, the network device can obtain, based on formula (1.1) or formula (1.2), SLIV corresponding to each part of the first information.

[00257] Third, the network device may map the SLIV value and the index for each set of first information according to one of the following rules.

[00258] 1. Sort SLIV in ascending order (or descending order) L:

for the same L, sort SLIV in ascending order of S;

for the same L, sort SLIV in descending order of S;

for the same L, sort SLIV in ascending order of SLIV; or

for the same L, sort SLIV in SLIV descending order.

[00259] For sorted SLIVs, an index is sequentially added to each SLIV value in top-to-bottom order.

When the time domain resource information includes a display type parameter, the display type parameters in four parts of the time domain resource information are type 1, type 1, type 1, and type 2. When the time domain resource information includes the S parameter, the S parameter may be preset, for example, the S parameter may be preset as 0. When the time domain resource information includes a parameter K, the parameter K may be preset, and a pair meter K can be preset as 0.

[00272] In the example of the present application, when each of the plurality of pieces of predefined time domain resource information does not include the S parameter of uplink data or downlink data, the S parameter is preset, and the S parameter may be preset as 0.

[00273] In another example of the present application, each of the plurality of pieces of predefined time domain resource information may include at least one of a K parameter, an indication parameter, and a mapping type parameter of uplink data or downlink data. In the embodiment of the present application, when the four pieces of time domain resource information are preset and the time domain resource information includes an indication parameter, the indication parameters in the four pieces of time domain resource information are V1, V2, V3 and V4, and V1 , V2, V3 and V4 are each a positive number. When the value of V1 is 0, it indicates that the initial location of the time domain symbols occupied by the uplink data or the downlink data is 0 and that the number of occupied time domain symbols is 2. When the value of V2 is 1, it indicates that the initial the location of the time domain symbols occupied by the uplink data or the downlink data is 0 and that the number of occupied time domain symbols is 4. When the value of V3 is 84, it indicates that the initial location of the time domain symbols occupied by the uplink data or downlink data is 0 and that the number of occupied time domain symbols is 7. When the value of V4 is 27, it indicates that the initial location of the time domain symbols occupied by uplink data or downlink data is 0 and that the number of occupied time domain characters is 14. When the time resource information This area includes a display type parameter, the display type parameters in the four pieces of time domain resource information are type 1, type 1, type 1, and type 2. When there are at least three pieces of predefined time domain resource information, and the information time domain resource information includes an indication parameter, the indication parameters in at least three pieces of time domain resource information are V1, V2, and V3, where V1, V2, and V3 are each a positive number. When the value of V1 is 0, it indicates that the initial location of the time domain symbols occupied by uplink data or downlink data is 0 and that the number of occupied time domain symbols is 2. When the value of V2 is 1, it indicates that the initial the location of the time domain symbols occupied by the uplink data or the downlink data is 0 and that the number of occupied time domain symbols is 4. When the value of V3 is 84, it indicates that the initial location of the time domain symbols occupied by the uplink data or downlink data is 0 and that the number of occupied time domain symbols is 7. When the time domain resource information includes a mapping type parameter, the mapping type parameters in each of the at least three pieces of time domain resource information are of type 1.

[00274] In the example of the present application, when each of the plurality of pieces of predefined time domain resource information does not include the K parameter of uplink data or downlink data, the parameter K is preset, and the parameter K may be preset as 0.

[00275] In the example of the present application, when each of the plurality of pieces of predefined time domain resource information does not include the S parameter of uplink data or downlink data, the S parameter is preset, and the S parameter may be preset as 0.

[00276] In this embodiment of the present application, the parameter K is used to represent the location of the start slot occupied by uplink data or downlink data, the parameter S is used to represent the start location of time domain symbols occupied by uplink data or downlink data , the L parameter is used to represent the number of time domain symbols occupied by the uplink data or the downlink data, the mapping type parameter is used to represent the mapping type of the uplink data or downlink data, and the indication parameter is used to represent the initial position of the time domain symbols. area occupied by uplink data or downlink data, and the number of time domain symbols occupied.

[00277] Step S402: The network device sends the first indication information, where the first indication information may be downlink control information (DCI).

[00278] Step S403: The terminal apparatus determines, according to the first indication information, time domain resource information corresponding to the uplink data or the downlink data.

[00279] In the example of the present application, when four time domain resources are preset, and each time domain resource includes a K parameter, an S parameter, an L parameter, and a display type parameter, the K parameter is represented as K0, the S parameter is denoted as "start" , the L parameter is represented as "length", and the mapping type parameter is represented by the PDSCH mapping type. For the four predefined time domain resources, refer to the following Table 8.

Table 8

Index K0 Start Length PDSCH mapping type 0 k1 S1 2 Type 1 one k2 S2 four Type 1 2 k3 S3 7 Type 1 3 k4 S4 i(i>7) Type 2

[00280] In Table 8, K0 is used to determine the initial downlink data slot, and K0 may be preset, for example, preset that k1=k2=k3=k4=0. In this case, the column K0 may not be present in the table.

[00281] In Table 8, the location of the "beginning" may be indicated by the protocol. "Start" may be determined based on a slot boundary, or may be determined based on the location of the PDCCH start symbol, and this is not limited here. When "Start" is 0, it indicates that the "Start" location is the first symbol relative to the slot boundary, or that the "Start" location is 0 relative to the PDCCH start symbol, or that the "Start" location is 0 relative to the PDCCH end symbol. "Start" may be predefined, such as predefined that s1=s2=s3=s4=0. In this case, the table may not have a "start" column.

[00282] In Table 8, L may be predefined as 2, 4, 7, and i, which respectively indicate that the downlink data respectively occupy two time-domain symbols, four time-domain symbols, seven time-domain symbols, and i time-domain symbols in one slot. L - length relative to the location of the "beginning".

[00283] In Table 8, the PDSCH mapping type may be predefined in the protocol, for example, the predefined mapping type may be type 1 or type 2.

[00284] In the example of the present application, when four time domain resources are preset, and each piece of time domain resource information may include a parameter K, an indication parameter, and a display type parameter of uplink data or downlink data, the parameter K may be represented as K0, the indication parameter may be represented as SLIV, and the mapping type parameter is represented by the PDSCH mapping type. For the four predefined time domain resources, refer to the following Table 9.

Table 9

Index K0 SLIV PDSCH mapping type 0 k1 V1 Type 1 one k2 V2 Type 1 2 k3 V3 Type 1 3 k4 V4 Type 2

[00285] In Table 9, K0 is used to represent the initial downlink data slot, and K0 may be preset, for example, preset that k1=k2=k3=k4=0. In this case, the column K0 may not be present in the table.

[00286] In Table 9, the value of SLIV may also be predefined, and the initial location and length corresponding to SLIV satisfy the following condition: the initial location is determined by the protocol and may be determined based on the slot boundary, or may be determined based on the location of the PDCCH start symbol. For example, when the start location is 0, it indicates that the start location is the first symbol relative to the slot boundary, or that the start location is 0 relative to the PDCCH start symbol, or that the start location is 0 relative to the end PDCCH symbol. When the length is 2, 4, 7, or 14, it means that the data length is two symbols, four symbols, or i symbols, and i symbols represent the number of time domain symbols included in one slot.

[00287] In Table 9, the PDSCH mapping type may be preset in the protocol, and may be preset as type 1 or type 2.
