[0060] Illustrative embodiments will now be described in detail, examples of which are illustrated in the drawings. When the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following illustrative examples do not represent all embodiments consistent with the present invention. Rather, they are merely apparatus and methods consistent with certain aspects of the present invention as set forth in the appended claims.

[0061] The terms used in this disclosure are intended only to describe particular embodiments and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "the," and "said" are also intended to include the plural forms unless the context clearly dictates otherwise. The term "and / or," as used herein, should be understood to mean including any and all possible combinations of one or more of the associated listed items.

[0062] In this disclosure, terms such as first, second, and third may be used to describe various pieces of information, but it should be understood that such information should not be limited to these terms. These terms are used only to distinguish between the same types of information. For example, instructional information may be referred to as second information, and similarly, second information may be referred to as instructional information, without departing from the scope of this disclosure. Depending on the context, the word "when" as used herein may be interpreted as "when," "in the event of," or "responsive to a determination."

[0063] FIG. 1 is a flowchart of a transmission instruction method shown in an exemplary embodiment, and FIG. 2 is an application scenario diagram of the transmission instruction method shown in an exemplary embodiment, which may be used in a base station. As shown in FIG. 1, the transmission instruction method may include the following steps 110 to 130.

[0064] In step 110, a first number of designated time units (time units) where the first number is an integer greater than one.

[0065] In the embodiments of the present disclosure, a base station can schedule a terminal to receive a TB or transmit a TB, so "transmitting a TB" in the present disclosure can include receiving a TB and transmitting a TB. Specifically, in the case of a downlink, a terminal receives a TB, and in the case of an uplink, a terminal transmits a TB. "Transmitting a TB" in all subsequent embodiments is the same as this, and will not be described in detail.

[0066] When the same TB is to be repeatedly transmitted N times, the time domain resource used is different from the beam, and other resources are the same. In this case, the TB can be scheduled to be repeatedly transmitted at different times using different beams. Here, the other resources can include frequency domain resources, modulation and coding schemes, HARQ (Hybrid Automatic Repeat reQuest) process numbers, etc.

[0067] For different TBs, multiple designated time units can be scheduled for transmission in one DCI, and different time domain resources and beams can be used, and different TBs use different HARQ process numbers.

[0068] For example, the first number is K, and it is determined that one TB is to be transmitted in K designated time units, i.e., the TB needs to be transmitted in each designated time unit of the K designated time units.

[0069] For example, the first number is K, and two TBs, a first TB and a second TB, are transmitted in K designated time units. That is, the first TB is transmitted in some of the K designated time units, and the second TB is transmitted in another designated time unit.

[0070] Furthermore, for example, the first number is K, and K TBs are transmitted in K designated time units, that is, each designated time unit among the K designated time units transmits one TB, and the TB transmitted in each designated time unit is different.

[0071] In one embodiment, the designated time unit in step 110 may be a designated mini-slot, and the specific transmission instruction process may refer to the embodiment shown in FIG.

[0072] In one embodiment, the designated time unit in step 110 may be a designated slot, and the specific transmission instruction process may refer to the embodiment shown in FIG.

[0073] In step 120, a first DCI signaling is generated to indicate that a TB is to be transmitted in each designated time unit.

[0074] In an embodiment of the present disclosure, the base station can instruct the terminal via DCI signaling to transmit a TB in each designated time unit.

[0075] In step 130, a first DCI signaling is sent to the terminal so that the terminal transmits a TB in each designated time unit based on the first DCI signaling.

[0076] An exemplary scenario includes a base station 11 and a terminal 12, as shown in Figure 2. When the base station 11 determines to transmit one or more TBs in a first number of designated time units, the base station 11 can generate first DCI signaling. The first DCI signaling is used to instruct the terminal 12 to transmit a TB in each designated time unit and to transmit the first DCI signaling. Thus, after receiving the first DCI signaling, the terminal 12 can transmit a TB in each designated time unit based on the one DCI signaling.

[0077] In the present disclosure, the base station 11 may be a device disposed in an access network and providing wireless communication functions for terminals 12. The base station 11 may include various types of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the name of a device having base station functions may differ; for example, in a 5G NR system, it is called a gNodeB or gNB. As communication technologies evolve, the name of the "base station" may change. For ease of explanation, in the embodiments of the present disclosure, the above devices providing wireless communication functions for terminals 12 are collectively referred to as base stations.

[0078] The number of terminals 12 is generally plural, and one or more terminals 12 may be distributed in a cell managed by each base station 11. The terminals 12 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, each equipped with wireless communication capabilities, as well as various forms of user equipment (UE), mobile stations (MS), terminal devices, etc. For ease of explanation, the above devices are collectively referred to as terminals in the embodiments of the present disclosure.

[0079] As can be seen from the above embodiment, when it is determined to transmit one or more TBs in a first number of designated time units, a first DCI signaling can be generated to instruct the terminal to transmit a TB in each designated time unit and to send a first DCI signaling to the terminal, so that after receiving the first DCI signaling, the terminal can transmit a TB in each designated time unit based on the first DCI signaling, and the DCI instruction can be used to transmit a TB in different time units using different beam directions, thereby improving communication robustness.

[0080] 3 is a flowchart of another transmission instruction method according to an exemplary embodiment, which may be used in a base station. Based on the method shown in FIG. 1, the first number of designated time units may be a first number of designated minislots, and performing step 120 may include the following steps 310 to 320, as shown in FIG. 3.

[0081] In step 310, the starting symbol position and number of symbols for each designated minislot is determined.

[0082] In an embodiment of the present disclosure, one designated time unit may be one designated minislot, the number of symbols included in each designated minislot may be the same or different, and the first DCI signaling needs to explicitly specify the position of the starting symbol and the number of symbols of each designated minislot.

[0083] In one embodiment, the number of slots occupied by each designated minislot in step 310 is a second number, the second number is an integer greater than 0, the second number is less than or equal to the first number, and all symbols in one designated minislot are within one slot and cannot span different slots.

[0084] For example, the first number is K and the second number is N, where K is greater than or equal to N. Here, if K is equal to N, a slot has only one minislot, and if K is greater than N, some slots have only one minislot, but some slots have multiple minislots.

[0085] In one embodiment, each of the designated minislots in step 310 above may include adjacent and / or non-adjacent minislots.

[0086] For example, the i-th designated minislot and the i+1-th designated minislot are adjacent, i.e., the last symbol of the i-th minislot is adjacent to the starting symbol of the i+1-th minislot, or the i-th designated minislot is not adjacent, i.e., there is an interval symbol between the last symbol of the i-th minislot and the starting symbol of the i+1-th minislot, or the i-th designated minislot and the i+1-th designated minislot are adjacent when i is set to one value and not adjacent when i is set to another value.

[0087] In step 320, the starting symbol position and number of symbols for each designated minislot are added to the first DCI.

[0088] As can be seen from the above embodiment, by determining the position and number of the starting symbol of each designated mini-slot and adding the position and number of the starting symbol of each designated mini-slot to the first DCI signaling, it becomes easy for the terminal to transmit the TB based on the position and number of the starting symbol of each designated mini-slot in the first DCI signaling, and the accuracy of the transmission instruction can be improved.

[0089] 4 is a flowchart of another transmission instruction method according to an exemplary embodiment, which may be used in a base station. Based on the method shown in FIG. 1, the first number of designated time units may be a first number of designated slots, and when performing step 120, the method may include the following steps 410 to 420, as shown in FIG. 4.

[0090] In step 410, the location of the designated start symbol and the location of the designated end symbol for each designated slot are determined.

[0091] In an embodiment of the present disclosure, one designated time unit may be one designated slot, and the first DCI signaling needs to explicitly specify the position of the transmission designated start symbol and the position of the designated end symbol of each designated slot.

[0092] In one embodiment, the position of the designated start symbol in step 410 is the first designated slot among the designated slots, and the positions of the start symbols of other designated slots are the first symbols, or the positions of the designated start symbols are each designated slot among the designated slots.

[0093] In one embodiment, the position of the designated end symbol in step 410 is the last designated slot among the designated slots, and the positions of the end symbols of the other designated slots are the last symbols. Alternatively, the position of the designated end symbol is each designated slot among the designated slots.

[0094] In one embodiment, each of the designated slots in the first number of designated slots may be adjacent slots.

[0095] In step 420, a designated start symbol position and a designated end symbol position are added to the first DCI signaling.

[0096] As can be seen from the above embodiment, by determining the position of the designated start symbol and the position of the designated end symbol of each designated slot and adding the position of the designated start symbol and the position of the designated end symbol to the first DCI signaling, it is easy for the terminal to transmit the TB based on the position of the designated start symbol and the position of the designated end symbol of the first DCI signaling, and the efficiency of the TB can be improved.

[0097] 5 is a flowchart of another transmission instruction method according to an exemplary embodiment, which may be used in a base station. When performing step 120 according to the method shown in FIG. 1, the method may include the following steps 510 to 520, as shown in FIG.

[0098] In step 510, beam designation information corresponding to each designated time unit is determined.

[0099] In the embodiment of the present disclosure, since the base station needs to inform the terminal of the beam that should be used when transmitting the TB by the beam indication information, the first DCI signaling needs to explicitly provide the beam indication information corresponding to each designated time unit, where one designated time unit may be one designated minislot or one designated slot.

[0100] The specific beam instruction information to which each designated time unit corresponds must be determined based on the number of beam instruction information to be assigned and the number of each designated time unit, and includes but is not limited to the following implementation methods.

[0101] Method 1: The number of beam instruction information to be allocated is a third number, the number of each designated time unit is a first number, and the third number is equal to the first number.

[0102] In this method, when step 510 is realized, (1-1) A step of allocating one beam instruction information to each of the designated time units, wherein the beam instruction information allocated to different designated time units is different, may be included.

[0103] For example, the first number is K and the third number is M, where K is equal to M, and one time unit corresponds to one beam indication information.

[0104] Method 2: The number of beam instruction information to be allocated is a fourth number, the number of each designated time unit is a first number, the fourth number is smaller than the first number, and the fourth number is an integer greater than 0. In this method, when step 510 is realized, (2-1) For each of the designated time units, the step of assigning one beam instruction information to each of the subsequent fourth number of the designated time units and assigning one default beam instruction information to each of the other designated time units may be included.

[0105] For example, the first number is K and the fourth number is P. Here, if K is greater than P and the difference between K and P is j, the beam direction information of the previous j designated time units may use default beam direction information, and the following P designated time units sequentially correspond to P beam direction information. If the time interval between the position of the start symbol of the previous designated time units and the position of the end symbol of the first DCI signaling is small, the terminal may not be able to obtain correct beam direction information by decoding during this time and adjust the receiving beam direction to the correct transmission beam, and the beam direction information of the previous designated time units may use default beam direction information.

[0106] Method 3: The number of beam instruction information to be allocated is a fifth number, the number of each specified time unit is a first number, the fifth number is smaller than the first number, and the fifth number is an integer greater than 0. In this method, when step 510 is performed, (3-1) dividing the first number of designated time units into the fifth number of time unit groups; (3-2) The method may include a step of calculating a time interval between each time unit in each time unit group and the first DCI signaling, assigning default beam indication information to a time unit whose time interval is smaller than a set threshold, and assigning one beam indication information of the fifth number of beam indication information to a time unit whose time interval is equal to or greater than the threshold, wherein different beam indication information of the fifth number of beam indication information is assigned to different time unit groups, and the time unit groups include a plurality of consecutive time units and / or a plurality of non-consecutive time units.

[0107] For example, the first number is K, the fifth number is 2, and the beam instruction information to be assigned includes first beam instruction information and second beam instruction information. Here, the K designated time units are divided into two time unit groups, and default beam instruction information can be assigned to a time unit of the two time unit groups whose time interval is smaller than a set threshold, the first beam instruction information can be assigned to a time unit of the first time unit group whose time interval is equal to or greater than the threshold, and the second beam instruction information can be assigned to a time unit of the second time unit group whose time interval is equal to or greater than the threshold.

[0108] Furthermore, for example, if the first number is K, which is an even number, the fifth number is 2, and the K designated time units are divided into two time unit groups, the first K / 2 designated time units can be the first time unit group and the last K / 2 designated time units can be the second time unit group. Alternatively, the designated time unit group with an odd number of time units, such as 1, 3, 5, 7, etc., can be the first time unit group, and the designated time unit group with an even number of time units, such as 2, 4, 6, 8, etc., can be the second time unit group; that is, the first time unit group can be the odd number group and the second time unit group can be the even number group.

[0109] Furthermore, for example, the first number is K, the fifth number is 1, and the beam instruction information to be assigned includes first beam instruction information. In this case, after calculating the time interval between each designated time unit and the first DCI, default beam instruction information is assigned to the designated time unit whose time interval is smaller than a set threshold, and the first beam instruction information is assigned to the designated time unit whose time interval is equal to or greater than the threshold.

[0110] Method 4: The number of beam instruction information to be allocated is a sixth number, the number of each specified time unit is a first number, the sixth number is smaller than the first number, and the sixth number is an integer greater than 0. In this method, when step 510 is performed, (4-1) calculating a time interval between each of the designated time units and the first DCI signaling, and assigning default beam instruction information to a time unit whose time interval is smaller than a set threshold; (4-2) The method may include a step of dividing the time units whose time interval is equal to or greater than the threshold into the sixth number of time unit groups, and assigning one beam instruction information of the sixth number of beam instruction information to each time unit group of the sixth number of time unit groups, wherein different beam instruction information of the sixth number of beam instruction information is assigned to different time unit groups, and the time unit groups include a plurality of consecutive time units and / or a plurality of non-consecutive time units.

[0111] For example, the first number is K, the fifth number is 2, and the beam instruction information to be assigned includes first beam instruction information and second beam instruction information. In this case, default beam instruction information is assigned to time units whose time interval is smaller than a set threshold, but time units whose time interval is equal to or larger than the set threshold are divided into a first time unit group and a second time unit group, and the first beam instruction information can be assigned to time units in the first time unit group and the second beam instruction information to time units in the second time unit group.

[0112] The difference between the above methods 3 and 4 is that in method 3, default beam instruction information is assigned after grouping, whereas in method 4, default beam instruction information is assigned before grouping.

[0113] In one embodiment, the beam indication information to be allocated in the above-mentioned methods 1, 2, 3, and 4 is a TCI (Transmission Configuration Indication) for indicating beam information used when a terminal receives data. Transmission Settings The information may include spatial relation information for indicating the state of the terminal and / or beam information used when the terminal transmits data.

[0114] In one embodiment, the default beam instruction information in (2-1), (3-2), and (4-1) above includes default TCI state and / or default spatial relationship information.

[0115] In one embodiment, the default TCI state is the same as the TCI state used when receiving the first DCI signaling, or the default TCI state is the same as the TCI state used when receiving the CORESET (control-resource set) with the smallest CORESET ID (index), and the CORESET and the first DCI signaling originate from the same antenna panel.

[0116] In one embodiment, the default spatial relationship information is the same as the spatial relationship information used to transmit the nearest PUCCH (Physical Uplink Control Channel), and the antenna panel used to transmit the PUCCH is the same as the antenna panel used to transmit the uplink data.

[0117] In step 520, beam indication information is added to the first DCI signaling.

[0118] In one embodiment, the first DCI signaling needs to explicitly provide the antenna panel identifier corresponding to each designated time unit, so that when performing step 520: (5-1) determining an antenna panel identifier corresponding to each of the designated time units; (5-2) adding the beam indication information and the antenna panel identifier to the first DCI signaling.

[0119] As can be seen from the above embodiments, by determining beam indication information and / or antenna panel identifier corresponding to each specified time unit and adding the beam indication information and / or antenna panel identifier to the first DCI signaling, it is possible to facilitate the terminal to transmit a TB based on the beam indication information and / or antenna panel identifier of the first DCI signaling, thereby improving the reliability of the terminal using a beam when transmitting a TB.

[0120] 6 is a flowchart of a transmission instruction method according to an exemplary embodiment, which may be used in a terminal. As shown in FIG. 6, the transmission instruction method may include the following steps 610 to 620.

[0121] In step 610, first DCI signaling is received, sent by a base station, to indicate transmission of one or more TBs in a first number of designated time units, where the first number is an integer greater than one.

[0122] In an embodiment of the present disclosure, the base station can schedule the terminal to receive or transmit the TB by DCI signaling.

[0123] For example, the first number is K, and the first DCI signaling indicates transmission of one TB in K designated time units, i.e., the terminal needs to transmit the TB in each designated time unit among the K designated time units.

[0124] Furthermore, for example, the first number is K, and the first DCI signaling indicates that two TBs, a first TB and a second TB, are to be transmitted in K designated time units, i.e., the first TB is transmitted in some designated time units among the K designated time units, and the second TB is transmitted in another designated time unit.

[0125] For example, the first number is K, and the first DCI signaling indicates that K TBs are to be transmitted in K designated time units, that is, each designated time unit among the K designated time units transmits one TB, and the TB transmitted in each designated time unit is different.

[0126] In step 620, transmit a TB in each designated time unit based on the first DCI signaling.

[0127] In the embodiments of the present disclosure, since the contents included in the first DCI signaling are different, TBs can be transmitted in each specified time unit based on these different contents, specifically including but not limited to the following cases:

[0128] Case 1: The designated time unit is a designated minislot, and the first DCI signaling includes the position of the starting symbol and the number of symbols of each designated minislot.

[0129] In this case, when performing step 620, the position and number of starting symbols of each designated mini-slot can be determined based on the first DCI signaling, and then the TB can be transmitted based on the position and number of starting symbols of each designated mini-slot.

[0130] Case 2: The designated time unit is a designated slot, and the first DCI signaling includes a designated start symbol position and a designated end symbol position of each of the designated slots.

[0131] In this case, when performing step 620, the position of a designated start symbol and the position of a designated end symbol for transmitting the TB can be determined based on the first DCI signaling, and then the TB can be transmitted based on the position of the designated start symbol and the position of the designated end symbol.

[0132] In one embodiment, the position of the designated start symbol is the first designated slot among the designated slots, and the positions of the start symbols of the other designated slots are the first symbols. Alternatively, the position of the designated start symbol is each designated slot among the designated slots.

[0133] In one embodiment, the position of the designated end symbol is the last designated slot among the designated slots, and the positions of the end symbols of the other designated slots are the last symbols, or the position of the designated end symbol is each designated slot among the designated slots.

[0134] Case 3: The first DCI signaling includes beam indication information corresponding to each of the specified time units.

[0135] In this case, when performing step 620, beam indication information corresponding to each of the specified time units can be determined based on the first DCI signaling, and then the TB can be transmitted based on the beam indication information.

[0136] Case 4: The first DCI signaling includes beam indication information and an antenna panel identifier corresponding to each of the designated time units.

[0137] In this case, when performing step 620, the beam indication information and antenna panel identifier corresponding to each of the specified time units can be determined based on the first DCI signaling, and then the TB can be transmitted based on the beam indication information and the antenna panel identifier.

[0138] In one embodiment, the beam indication information in cases 3 and 4 may include a TCI state for indicating beam information to be used when the terminal receives data, and / or spatial relationship information for indicating beam information to be used when the terminal transmits data.

[0139] As can be seen from the above embodiment, by receiving a first DCI signaling sent by a base station to instruct to transmit one or more TBs in a first number of designated time units, it is possible to transmit a TB in each designated time unit based on the first DCI signaling, thereby realizing the transmission of TBs in different time units using different beam directions through one DCI instruction, and also improving the robustness of communication.
