Detailed description of the invention

[00174] Hereinafter, the present invention will be described in more detail using specific examples of its implementation, which are illustrated in the attached drawings. The following description is made with reference to the accompanying drawings, where, unless otherwise indicated, the same or similar elements are designated by like symbols in various drawings. The implementations of the exemplary embodiments of the present invention discussed in the description below are not all possible implementations consistent with the present invention. On the contrary, they are solely examples of devices and methods according to the present invention, as defined by the appended claims.

[00175] The terms in this document are used solely to describe specific embodiments of the present invention and should not be construed as limiting the present invention. In the present description, as well as in the appended claims, expressions such as "one", "one of" and "mentioned" in the singular are intended to include the meanings in the plural as well, unless the context clearly indicates otherwise. It is also to be understood that the expression "and/or" as used herein represents, and includes, any of the elements listed in connection therewith, as well as all possible combinations thereof.

[00176] In this document, the expressions "first", "second", "third", and the like can be used to describe various information. However, it should be understood that the described information is not limited to these terms. They are used solely to distinguish information of the same type from each other. For example, within the scope of the present invention, the indication information may also be referred to as second information, and similarly, the second information may also be referred to as indication information. Depending on the context, the expression "if" in this document may be interpreted as "when" or "after", or as "in response to a determination of what".

[00177] FIG. 1 is a flowchart illustrating a transmission indication method in accordance with one embodiment of the present invention. Fig. 2 is a schematic block diagram illustrating one scenario for a transfer indication method according to one embodiment of the present invention. The transmission indication method may be applied in the base station. In accordance with the illustration of FIG. 1, the transmission indication method may include operations in blocks 110-130 described below.

[00178] At the UE block, it is determined that one or more transmission blocks (TBs) need to be transmitted in the first number of assigned time slots. The first number mentioned is an integer greater than 1.

[00179] In some of the embodiments of the present invention, the base station may schedule, for the terminal, to receive transmission blocks or schedule the transmission, by the terminal, of transmission blocks. Accordingly, the expression "transmitting transmission blocks" herein may include receiving transmission blocks or sending transmission blocks. In particular, when it comes to downlink, the terminal receives transmission blocks; if it is uplink, the terminal sends transmission blocks. The expression "transmission of transmission blocks" in all the following embodiments of the present invention is interpreted in the same way, which will not be described again.

[00180] For one transmission block, if it is retransmitted N times, the time resources and beams used are different, while the rest of the resources are identical. In this case, it is possible to schedule the retransmission of such a transmission block using different beams at different times. Said other resources may include frequency resources, modulation and coding modes, number of Hybrid Automatic Repeat reQuest (HARQ) processes, and the like.

[00181] For different transmission blocks, a plurality of assigned time slots for transmission of transmission blocks can be scheduled using a single DCI, using different time resources and beams, and using different numbers of HARQ processes for different transmission blocks.

[00182] For example, the first number may be equal to K, and then it is determined that one transmission block will be transmitted in K assigned time intervals. That is, this transmission block must be transmitted in each assigned slot of the K assigned slots.

[00183] In another example, the first number is K, and two transmission units, TB, namely the first TB and the second TB, are transmitted at K designated time intervals. That is, the first transmission block may be transmitted in some of the K assigned slots, and the second TV may be transmitted in the rest of the K assigned slots.

[00184] In yet another example, the first number is K, and K transmission blocks, TV, are transmitted in K assigned time slots. That is, one TV may be transmitted in each of the K assigned slots, and the TVs transmitted in each of the assigned slots may be different.

[00185] In some of the embodiments of the present invention, the assigned time slot in block 110 may be an assigned mini-slot. Such a transfer indication procedure is discussed in detail with the example of the embodiments of the present invention shown in FIG. 3.

[00186] In some of the embodiments of the present invention, the assigned slot in block 110 may be an assigned slot. Such a transfer indication procedure is discussed in detail with the example of the embodiments of the present invention shown in FIG. four.

[00187] In block 120, the first downlink control information (DCI) is generated. DCI signaling is configured to indicate that one or more transmission blocks are being transmitted at designated time intervals.

[00188] In some of the embodiments of the present invention, the base station may instruct the terminal to transmit one or more transmission blocks at designated time intervals using DCI signaling.

[00189] At block 130, the first DCI signaling is transmitted to the terminal such that the terminal transmits the one or more transmission blocks at the designated time intervals based on the first DCI signaling.

[00190] In one possible scenario, as illustrated in FIG. 2, there is a base station 11 and a terminal 12. When the base station 11 decides to transmit one or more transmission blocks in the first number of assigned slots, it may generate the first DCI signaling. The first DCI signaling is configured to indicate that one or more transmission blocks are being transmitted at the assigned time intervals. At block 130, the first DCI signaling is transmitted to the terminal, causing the terminal to transmit the one or more transmission blocks at the designated time intervals based on the first DCI signaling.

[00191] In the present invention, base station 11 may be a device located in an access network to provide terminal 12 with wireless communication functionality. The base station 11 may take various forms: macro base stations, micro base stations, relay stations, access points, and the like. In systems where different wireless access technologies are used, the names of devices that perform the functions of a base station may differ. For example, in fifth generation (5G) mobile communication systems, New Radio (New Radio, NR), the base station may be called gNodeB, or gNB. With the development of communication technologies, the term "base station" may change. For ease of description, in embodiments of the present invention, the above-mentioned device providing wireless communication functionality to terminal 12 may be generically referred to as a base station.

[00192] Typically, there are multiple terminals 12, whereby one or more terminals may be located in cells managed by each of the base stations 11. Terminal 12 may include various portable devices, vehicle-mounted devices, wearable devices, computing devices with wireless communication or other data processing devices associated with wireless modems, as well as various types of user equipment (UE), mobile stations (mobile stations, MS), terminal devices, and the like. For ease of description, in embodiments of the present invention, such devices are collectively referred to as terminals.

[00193] As follows from the above embodiments of the present invention, when it is decided to transmit one or more transmission blocks in the first number of assigned slots, the first DCI signaling can be generated, with the first DCI signaling configured to indicate that one or more transmission blocks are transmitted at the designated time intervals. The first DCI signaling is transmitted to the terminal, whereby the terminal can transmit one or more transmission blocks at the assigned time intervals based on the first DCI signaling after receiving the first DCI signaling, and thus realizing the indication of different beam directions by DCI signaling to transmit one or more transmission blocks in different time intervals and increase the reliability of communication.

[00194] FIG. 3 is a flowchart illustrating yet another method for indicating transmission in accordance with one embodiment of the present invention. This transmission indication method can be applied in the base station and is based on the method shown in FIG. 1. The first number of assigned slots may be the first number of assigned mini-slots. When the operation in block 120 is performed, in accordance with the illustration of FIG. 3, the operations from blocks 310-320 described below may be included.

[00195] In block 310, the start symbol position and the number of symbols for each assigned mini-slot are determined.

[00196] In some of the embodiments of the present invention, the assigned slot may be an assigned mini-slot. The symbols included in each designated mini slot may be the same or different. The first DCI signaling must clearly define the position of the start symbol and the number of symbols in each mini-slot.

[00197] In embodiments of the present invention, the number of slots occupied by the assigned mini-slots, in block 310, is a second number, wherein the second number is an integer greater than 0. The second number is less than or equal to the first number. All symbols in one assigned mini-slot are inside the same slot and cannot be placed in different slots.

[00198] For example, if the first number is K and the second number is N, where K is greater than or equal to N, then if K is N, then exactly one mini-slot can be present in each slot. If K is greater than N, some slots may contain one mini-slot, and some slots may contain multiple mini-slots.

[00199] In some of the embodiments of the present invention, the assigned mini-slots in block 310 may include adjacent mini-slots and/or non-adjacent mini-slots.

[00200] For example, the i-th assigned mini-slot may be adjacent to (i+1)-M assigned mini-slot, that is, the last symbol of the i-th mini-slot is adjacent to the start symbol (i+1)- th mini slot; or the i-th assigned mini-slot may not be adjacent to the (i+1)-M assigned mini-slot, i.e. there is some other symbol between the last symbol of the i-th mini-slot and the start symbol (i+1) -th mini-slot; or the i-th assigned mini-slot may be adjacent to the (i+1)-M assigned mini-slot for certain values of i, and not adjacent for other values of i.

[00201] At block 320, the start symbol position and the number of symbols, for each assigned mini-slot, are added to the first DCI signaling.

[00202] As follows from the above embodiments of the present invention, the position of the start symbol and the number of symbols for each assigned mini-slot can be determined. The position of the start symbols and the number of symbols, for each assigned mini-slot, is added to the first DCI signaling. Accordingly, the terminal can easily transmit one or more transmission blocks based on the positions of the start symbols and the number of symbols in the assigned mini-slots from the first DCI signaling, thereby improving the accuracy of the transmission indication.

[00203] FIG. 4 is a flowchart illustrating yet another method for indicating transmission in accordance with one embodiment of the present invention. This transmission indication method can be applied in the base station and is based on the method shown in FIG. 1. The first number of assigned slots may be the first number of assigned slots. When the operation in block 120 is performed, in accordance with the illustration of FIG. 4, the operations from blocks 410-420 described below may be included.

[00204] In block 410, an assigned start symbol position and an assigned end symbol position for each assigned slot are determined.

[00205] In some of the embodiments of the present invention, the assigned time slot may be an assigned slot. The assigned start symbol position and the assigned end symbol position related to the transmission of each assigned slot shall be clearly indicated in the first DCI signaling.

[00206] In some of the embodiments of the present invention, the assigned start symbol position in block 410 is the position of the first assigned slot of said assigned slots, and the start symbol positions of the remaining assigned slots are the first symbols of the remaining assigned slots; or the position of the designated start symbol is the position of each designated slot of said designated slots.

[00207] In some of the embodiments of the present invention, the position of the assigned end symbol in block 410 is the position of the last assigned slot of said assigned slots, and the end symbol positions of the remaining assigned slots are the last symbols of the remaining assigned slots; or the position of the assigned end symbol is the position of each assigned slot of said assigned slots.

[00208] In some of the embodiments of the present invention, the assigned slots from the first number of assigned slots may be adjacent slots.

[00209] At block 420, an assigned start symbol position and an assigned end symbol position are added to the first DCI signaling.

[00210] As follows from the above embodiments of the present invention, the start symbol position and the end symbol position for each assigned slot can be determined. An assigned start symbol position and an assigned end symbol position may be added to the first DCI signaling. Accordingly, the terminal can easily transmit one or more transmission blocks based on the position of the assigned start symbol and the position of the assigned end symbol from the first DCI signaling, thereby improving transmission efficiency of the transmission blocks.

[00211] FIG. 5 is a flowchart illustrating yet another method for indicating transmission in accordance with one embodiment of the present invention. This transmission indication method can be applied in the base station and is based on the method shown in FIG. 1. When the operation in block 120 is performed, in accordance with the illustration of FIG. 5, operations from blocks 510 520 described below can be included.

[00212] In block 510, beam indication information corresponding to each assigned slot is determined.

[00213] In some of the embodiments of the present invention, since the base station needs to inform the terminal, with the beam designation information, of the beam for transmitting transmission blocks, the first DCI signaling needs to clearly indicate the beam designation information corresponding to each assigned slot. The assigned slot may be an assigned mini-slot or an assigned slot.

[00214] The correspondence between the beam guidance information and each assigned slot may be determined based on the number of instances of the beam guidance information to be placed and the number of assigned slots, which may include, but is not limited to, the implementations described below.

[00215] Method 1: the number of instances of the beam indication information to be placed is the third number, the number of assigned slots is the first number, and the third number is equal to the first number.

[00216] In this method, when the operation at block 510 is performed, it may include the following.

[00217] (1-1) Instances of beam guidance information are placed at designated time slots, respectively. Different instances of the beam guidance information are placed in different assigned time slots.

[00218] For example, the first number may be equal to K, and the third number is equal to M, where K is equal to M. One time interval corresponds to one instance of beam indication information.

[00219] Method 2: the number of instances of the beam indication information to be allocated is the fourth number, the number of assigned slots is the first number, the fourth number is less than the first number, and the fourth number is an integer greater than 0.

[00220] In this method, when the operation at block 510 is performed, it may include the following.

[00221] (2-1) For assigned slots, instances of beam guidance information are placed in the fourth number of last assigned slots, respectively, and one instance of default beam guidance information is placed in each of the remaining assigned slots.

[00222] For example, the first number may be K and the fourth number is P, where K is greater than P. When the difference between K and P is j, the beam guidance information in the first j assigned slots may be the default beam guidance information, and the next P assigned slots may correspond to P successive instances of beam guidance information. Since the time intervals between the start symbol positions of the first few assigned slots and the end symbol position of the first DCI signaling are small, and the terminal may not obtain correct beam indication information by decoding and correct the receive beam direction to the correct transmission beam during this time period, in as the beam guidance information for the first few assigned slots, the default beam guidance information may be used.

[00223] Method 3: The number of instances of the beam indication information to be allocated is the fifth number, the number of assigned slots is the first number, the fifth number is less than the first number, and the fifth number is an integer greater than 0.

[00224] In this method, when the operation at block 510 is performed, it may include the following.

[00225] (3-1) The first number of assigned slots is divided by the fifth number of slot groups.

[00226] (3-2) Calculate the time interval between each of the time intervals in each group of time intervals and the first DCI signaling, wherein the default beam indication information is placed in the time interval for which the time interval is less than a predetermined threshold; and one of the fifth number of instances of the beam indication information is placed in a time interval for which the time interval is greater than or equal to the mentioned threshold, while different instances of the beam indication information from the fifth number of instances of the beam indication information are placed in different groups of time intervals, and the group of time intervals can include consecutive time slots and/or non-consecutive time slots.

[00227] For example, the first number may be K, and the fifth number may be 2. The allocated beam guidance information includes first beam guidance information and second beam guidance information. The "K" assigned time slots can be divided into two groups of time slots. In these two groups of time slots, the default beam guidance information is placed in those time slots whose time slots are smaller than a predetermined threshold. The first beam indication information is placed in those time intervals from the first group of time intervals, the time intervals for which are greater than or equal to the threshold, while the second beam indication information is placed in the time intervals from the second group, the time intervals for which are greater than or equal to the threshold.

[00228] In another example, the first number is K and is even, and the fifth number is 2. When the K assigned timeslots are divided into two groups of timeslots, the first K/2 assigned timeslots may be included in the first group of timeslots, and the remaining The K/2 assigned slots may be included in the second group of slots. Alternatively, odd-numbered slots, i.e. 1, 3, 5, 7…, may form a first group of slots, and even-numbered slots, i.e., 2, 4, 6, 8…, may form a second group. time intervals, that is, the first group of time intervals will be an odd group, and the second group of time intervals will be even.

[00229] In another example, the first number may be K, and the fifth number may be 1. The allocated beam guidance information includes the first beam guidance information. In this case, the time interval between each assigned slot and the first DCI alarm is calculated. In the time interval, the time interval for which is less than the predetermined threshold, the default beam indication information is placed. In the time interval, the time interval for which is greater than or equal to the mentioned threshold, the first beam indication information is placed.

[00230] Method 4: The number of instances of the beam indication information to be allocated is the sixth number, the number of assigned slots is the first number, the sixth number is less than the first number, and the sixth number is an integer greater than 0.

[00231] In this method, when the operation at block 510 is performed, it may include the following.

[00232] (4-1) The time interval between each of the assigned time intervals and the first DCI signaling is calculated, wherein the default beam guidance information is placed in the time interval for which the time interval is less than the predetermined threshold.

[00233] The time intervals for which the time intervals are greater than or equal to the mentioned threshold are divided into a sixth number of time interval groups, and one of the sixth number of beam indication information instances is placed in each group of the sixth number of time interval groups, while in different interval groups time, different instances of the beam indication information from the sixth number of instances of the beam indication information are arranged, and the group of time intervals may include consecutive time intervals and/or non-consecutive time intervals.

[00234] For example, the first number may be K, and the fifth number may be 2. The allocated beam guidance information includes first beam guidance information and second beam guidance information. In time intervals whose time intervals are less than a predetermined threshold, default beam indication information is placed. The time intervals, the time intervals for which are greater than or equal to the mentioned threshold, are divided into the first group of time intervals and the second group of time intervals. The first beam indication information is placed in slots in the first group of slots. The second beam indication information is placed in slots in the second group of slots.

[00235] The difference between method 3 and method 4 is that method 3 is grouping first and then placing default beam guidance information, and method 4 is first placing default beam guidance information and then grouping.

[00236] In some of the embodiments of the present invention, the allocated beam indication information in method 1, method 2, method 3, and method 4 may include a transmission configuration indication (TCI) state for indicating beam information used when the terminal receives data; and/or relative spatial location information for indicating beam information used when the terminal transmits data.

[00237] In some of the embodiments of the present invention, the default beam indication information in (2-1), (3-2), and (4-1) may include a default TCI state and/or default relative spatial location.

[00238] In some of the embodiments of the present invention, 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 control resource set (CORESET) with the lowest index, with CORESET and the first DCI signaling coming from the same antenna panel.

[00239] In some of the embodiments of the present invention, the default relative spatial location information is the same as the relative spatial location information used in the transmission of the latest uplink control channel (PUCCH), wherein the antenna panel used in the transmission of said PUCCH is the same as the antenna panel used in uplink data transmission.

[00240] In block 520, beam guidance information is added to the first DCI signaling.

[00241] In some of the embodiments of the present invention, the first DCI signaling must also clearly provide the identifier of the antenna panel corresponding to each assigned slot. Accordingly, when the operation at block 520 is performed, it may include the following.

[00242] (5-1) Determine the identifiers of the antenna panels corresponding to the assigned time slots.

[00243] (5-2) Beam designation information and antenna panel identifiers are added to the first DCI signaling.

[00244] As follows from the embodiments of the present invention described above, beam guidance information and/or antenna panel identifiers corresponding to assigned time intervals can be determined. Beam guidance information and/or antenna panel identifiers may be added to the first DCI signaling. Accordingly, the terminal can easily transmit transmission blocks based on beam designation information and antenna panel IDs from DCI signaling, which can improve the reliability of beam usage by the terminal when transmitting transmission blocks.

[00245] FIG. 6 is a flowchart illustrating a transmission indication method in accordance with one embodiment of the present invention. The proposed transmission indication method can be applied in the terminal. In accordance with the illustration of FIG. 6, the transmission indication method may include the steps of blocks 610-620 described below.

[00246] At block 610, a first downlink control information (DCI) signaling is received from the base station, wherein the first DCI signaling is configured to indicate that one or more transmission units (TBs) are being transmitted in a first number of assigned time slots, where the first number is an integer greater than 1.

[00247] In some of the embodiments of the present invention, the base station may schedule, for the terminal, to receive one or more transmission blocks, or schedule the terminal to transmit one or more transmission blocks using DCI signaling.

[00248] For example, the first number may be equal to K, and the first DCI signaling indicate that one transmission block is transmitted in K assigned time intervals. In other words, the terminal must transmit a transmission block in each of the K assigned slots.

[00249] In another example, the first number may be equal to K, and the first DCI signaling indicates that two transmission blocks, TV, namely the first TV and the second TV, are transmitted in K assigned time slots. That is, the first transmission block may be transmitted in some of the K assigned slots, and the second TV may be transmitted in the rest of the K assigned slots.

[00250] In another example, the first number may be K, and the first DCI signaling may indicate that K transmission blocks are being transmitted in K assigned slots. That is, one TV may be transmitted in each of the K assigned time slots, and different TVs may be transmitted in different assigned time slots.

[00251] At block 620, transmission blocks are transmitted at assigned time intervals based on the first DCI signaling.

[00252] In some of the embodiments of the present invention, since the content of the first DCI signaling may be different, transmission blocks may be transmitted at assigned time intervals based on this different content, including but not limited to the cases described below.

[00253] Case 1: the assigned slot is the assigned mini-slot; wherein the first DCI signaling includes the position of the start symbol and the number of symbols in each assigned mini-slot.

[00254] In this case, when the operation at block 620 is performed, the start symbol position and number of symbols for each assigned mini-slot can be determined based on the first DCI signaling. One or more transmission blocks may be transmitted based on the position of the start symbol and the number of symbols, for each assigned mini-slot.

[00255] Case 2: the assigned slot is the assigned slot; wherein the first DCI signaling includes an assigned start symbol position and an assigned end symbol position for each assigned slot.

[00256] In this case, when the operation at block 620 is performed, a start symbol position and an end symbol position can be determined based on the first DCI signaling for transmitting one or more transmission blocks for each assigned mini-slot. One or more transmission blocks may be transmitted based on the position of the assigned start symbol and the position of the assigned end symbol.

[00257] In some of the embodiments of the present invention, the assigned start symbol position is the position of the first assigned slot of said assigned slots, and the start symbol positions of the remaining assigned slots are the first symbols of the remaining assigned slots; or, the position of the assigned start symbol is the position of each assigned slot of said assigned slots.

[00258] In some of the embodiments of the present invention, the position of the assigned end symbol is the position of the last assigned slot of said assigned slots, and the end symbol positions of the remaining assigned slots are the last symbols of the remaining assigned slots; or, the position of the assigned end symbol is the position of each assigned slot of said assigned slots.

[00259] Case 3: The first DCI signaling includes beam guidance information corresponding to the assigned slots.

[00260] In this case, when the operation in block 620 is performed, beam guidance information corresponding to the assigned time intervals can be determined based on the first DCI signaling. The transmission blocks may be transmitted based on the beam indication information.

[00261] Case 4: The first DCI signaling includes beam designation information and antenna panel identifiers corresponding to each of the assigned slots.

[00262] In this case, when the operation in block 620 is performed, the beam guidance information and the antenna panel identifier corresponding to the assigned time intervals can be determined based on the first DCI signaling. One or more transmission blocks may be transmitted based on the beam designation information and the antenna panel ID.

[00263] In some of the embodiments of the present invention, the beam indication information in case 1, case 2, case 3, and case 4 may include a transmission configuration indication (TCI) state for indicating beam information used when the terminal receives data; and/or relative spatial location information for indicating beam information used when the terminal transmits data.

[00264] As follows from the above embodiments of the present invention, the first DCI signaling is received from the base station, with the first DCI signaling configured to indicate that one or more transmission blocks are transmitted in the first number of assigned time intervals. One or more transmission blocks are transmitted at assigned time intervals based on the first DCI signaling, thus realizing the indication of different beam directions with one DCI signaling to transmit one or more transmission blocks at different time intervals, and improve communication reliability.
