Description

[0176] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0177] The terminology used in this disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The singular forms “a,” “the,” and “the” as used in this disclosure and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0178] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various types of information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, instruction information may also be referred to as second information, and similarly, second information may also be referred to as instruction information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0179] Figure 1 This is a flowchart illustrating a transmission indication method according to an exemplary embodiment. Figure 2 This is an application scenario diagram illustrating a transmission indication method according to an exemplary embodiment; the transmission indication method can be used in a base station, such as... Figure 1 As shown, the transmission indication method may include the following steps 110-130:

[0180] In step 110, it is determined that one or more TBs will be transmitted over a first number of specified time units. Wherein, the first number is an integer greater than 1.

[0181] In this embodiment of the disclosure, the base station can schedule the terminal to receive TB or schedule the terminal to send TB. Therefore, "transmitting TB" in this disclosure can include receiving TB or sending TB. Specifically, if it is downlink, the terminal receives TB; if it is uplink, the terminal sends TB. Furthermore, "transmitting TB" in all subsequent embodiments is the same and will not be repeated here.

[0182] For the same TB (Transmission Quantity), if it needs to be transmitted N times, and all other resources are the same except for the time-domain resources and beams used, then different beams can be scheduled to transmit the TB repeatedly at different times. These other resources may include frequency-domain resources, modulation and coding schemes, and HARQ (Hybrid Automatic Repeat reQuest) process numbers.

[0183] For different TBs, multiple specified time units can be scheduled for transmission in a single DCI, using different time domain resources and beams, and different TBs use different HARQ process numbers.

[0184] For example: the first quantity is K, and it is determined that one TB will be transmitted over K specified time units. That is to say, the TB needs to be transmitted in every specified time unit among the K specified time units.

[0185] For example, if the first quantity is K, and two TBs are transmitted over K specified time units, specifically the first TB and the second TB. That is, a portion of these K specified time units are used to transmit the first TB, and another portion are used to transmit the second TB.

[0186] For example, if the first quantity is K, then K TB are transmitted over K specified time units. That is, one TB is transmitted in each of these K specified time units, and the number of TB transmitted in each specified time unit is different.

[0187] In one embodiment, the specified time unit in step 110 above can be a specified mini-slot, and the specific transmission indication process can be found in the following example. Figure 3 The illustrated embodiment.

[0188] In one embodiment, the specified time unit in step 110 above can be a specified time slot, and the specific transmission indication process can be found in the following example. Figure 4 The illustrated embodiment.

[0189] In step 120, a first DCI signaling is generated, which is used to indicate the transmission of TB in each specified time unit.

[0190] In this embodiment of the disclosure, the base station can instruct the terminal to transmit TB in each specified time unit via DCI signaling.

[0191] In step 130, a first DCI signaling is sent to the terminal so that the terminal transmits TB in each specified time unit according to the first DCI signaling.

[0192] In an instance scenario, such as Figure 2 As shown, the system includes a base station 11 and a terminal 12. When the base station 11 determines that one or more TBs will be transmitted in a first number of designated time units, it can generate a first DCI signaling, which is used to instruct the transmission of TBs in each designated time unit, and send the first DCI signaling to the terminal 12. After receiving the first DCI signaling, the terminal 12 can transmit TBs in each designated time unit according to the first DCI signaling.

[0193] In this disclosure, base station 11 can be a device deployed in an access network to provide wireless communication functionality to terminal 12. Base station 11 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with base station functionality may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "base station" may change. For ease of description, in the embodiments of this disclosure, the device described above that provides wireless communication functionality to terminal 12 is collectively referred to as a base station.

[0194] The number of terminals 12 is typically multiple, with one or more terminals 12 distributed within the cell managed by each base station 11. Terminals 12 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), terminal device, etc. For ease of description, in this embodiment of the disclosure, the devices mentioned above are collectively referred to as terminals.

[0195] As can be seen from the above embodiments, when it is determined that one or more TBs will be transmitted in a first number of specified time units, a first DCI signaling can be generated. The first DCI signaling is used to indicate the transmission of TBs in each specified time unit and to send the first DCI signaling to the terminal. In this way, after receiving the first DCI signaling, the terminal can transmit TBs in each specified time unit according to the first DCI signaling, thereby realizing the transmission of TBs in different time units using different beam directions through DCI indication, and also improving communication robustness.

[0196] Figure 3 This is a flowchart illustrating another transmission indication method according to an exemplary embodiment. This transmission indication method can be used in a base station and is established on... Figure 1 Based on the method shown, the first number of specified time units can be the first number of specified micro-time slots, as shown in step 120. Figure 3 As shown, the steps 310-320 may be included:

[0197] In step 310, the starting symbol position and symbol number of each specified micro-timeslot are determined.

[0198] In this embodiment of the disclosure, a specified time unit can be a specified micro-time slot, and the number of symbols contained in each specified micro-time slot can be the same or different; and the first DCI signaling needs to explicitly give the starting symbol position and the number of symbols for each specified micro-time slot.

[0199] In one embodiment, the total number of time slots occupied by each of the specified micro-time slots in step 310 above is a second number, and the second number is an integer greater than 0. The second number is less than or equal to the first number, and all symbols of a specified micro-time slot are within one time slot and cannot span different time slots.

[0200] For example: the first quantity is K, the second quantity is N, where K is greater than or equal to N. If K equals N, then there can be only one micro-timeslot within a time slot; if K is greater than N, then some time slots can have only one micro-timeslot, while others can have multiple micro-timeslots.

[0201] In one embodiment, each of the designated microtime slots in step 310 above may include adjacent microtime slots and / or non-adjacent microtime slots.

[0202] For example: the i-th specified micro-slot and the (i+1)-th specified micro-slot are adjacent, that is, the last symbol of the i-th micro-slot is adjacent to the starting symbol of the (i+1)-th micro-slot; or, the i-th specified micro-slot and the (i+1)-th specified micro-slot are not adjacent, that is, there is an interval symbol between the last symbol of the i-th micro-slot and the starting symbol of the (i+1)-th micro-slot; or, the i-th specified micro-slot and the (i+1)-th specified micro-slot are adjacent when i takes some values ​​and not adjacent when i takes other values.

[0203] In step 320, the starting symbol position and symbol number of each specified micro-slot are added to the first DCI signaling.

[0204] As can be seen from the above embodiments, the starting symbol position and symbol number of each specified micro-time slot can be determined, and the starting symbol position and symbol number of each specified micro-time slot can be added to the first DCI signaling. This makes it easier for the terminal to transmit TB according to the starting symbol position and symbol number of each specified micro-time slot in the first DCI signaling, thereby improving the accuracy of transmission indication.

[0205] Figure 4 This is a flowchart illustrating another transmission indication method according to an exemplary embodiment. This transmission indication method can be used in a base station and is established on... Figure 1 Based on the method shown, the first number of specified time units can be the first number of specified time slots. When executing step 120, as follows... Figure 4 As shown, the steps 410-420 may be included:

[0206] In step 410, the specified start symbol position and specified end symbol position of each specified time slot are determined.

[0207] In this embodiment of the disclosure, a specified time unit can be a specified time slot, and the first DCI signaling needs to explicitly specify the specified start symbol position and specified end symbol position for the transmission of each specified time slot.

[0208] In one embodiment, the specified start symbol position in step 410 above is for the first specified time slot among the various specified time slots, while the start symbol position of the other specified time slots is the first symbol; or the specified start symbol position is for each specified time slot among the various specified time slots.

[0209] In one embodiment, the specified end symbol position in step 410 above refers to the last specified time slot among the various specified time slots, while the end symbol position of the other specified time slots is the last symbol; or the specified end symbol position refers to each specified time slot among the various specified time slots.

[0210] In one embodiment, each of the designated time slots in the first number of designated time slots may be an adjacent time slot.

[0211] In step 420, the specified start symbol position and the specified end symbol position are added to the first DCI signaling.

[0212] As can be seen from the above embodiments, the specified start symbol position and specified end symbol position of each specified time slot can be determined, and the specified start symbol position and specified end symbol position can be added to the first DCI signaling. This makes it easier for the terminal to transmit TB according to the specified start symbol position and specified end symbol position of the first DCI signaling, thereby improving the efficiency of TB transmission.

[0213] Figure 5 This is a flowchart illustrating another transmission indication method according to an exemplary embodiment. This transmission indication method can be used in a base station and is established on... Figure 1 Based on the method shown, when performing step 120, as follows: Figure 5 As shown, the steps 510-520 may be included:

[0214] In step 510, the beam indication information corresponding to each specified time unit is determined.

[0215] In this embodiment of the disclosure, since the base station needs to inform the terminal of the beam to be used when transmitting TB through beam indication information, the first DCI signaling needs to explicitly provide the beam indication information corresponding to each specified time unit. A specified time unit can be a specified micro-timeslot or a specified timeslot.

[0216] As for which specific beam indication information corresponds to each designated time unit, this depends on the number of beam indication information to be assigned and the number of each designated time unit, and can be implemented in ways including but not limited to the following:

[0217] Method 1: The number of beam indication information to be assigned is the third number, and the number of each specified time unit is the first number, wherein the third number is equal to the first number.

[0218] In this approach, step 510 may include:

[0219] (1-1) A beam indication information is assigned to each specified time unit, and the beam indication information assigned to different specified time units is different.

[0220] For example, the first quantity is K, the third quantity is M, where K equals M, and in this case, one time unit corresponds to one beam indication information.

[0221] Method 2: The number of beam indication information to be allocated is the fourth quantity, and the number of each specified time unit is the first quantity. The fourth quantity is less than the first quantity, and the fourth quantity is an integer greater than 0.

[0222] In this approach, step 510 may include:

[0223] (2-1) For each of the specified time units, assign a beam indication information to each of the fourth number of specified time units mentioned later, and assign a default beam indication information to each of the other specified time units.

[0224] For example, if the first quantity is K and the fourth quantity is P, where K is greater than P, and the difference between K and P is j, the beam indication information for the first j specified time units can use the default beam indication information. The subsequent P specified time units correspond to P beam indication information sequentially. Since the time interval between the start symbol position and the end symbol position of the first DCI signaling in the first few specified time units is small, and the terminal cannot decode the correct beam indication information and adjust the receiving beam direction to the correct transmission beam within this time, the default beam indication information can be used for the first few specified time units.

[0225] Method 3: The number of beam indication information to be assigned is the fifth number, and the number of each specified time unit is the first number. The fifth number is less than the first number, and the fifth number is an integer greater than 0.

[0226] In this approach, step 510 may include:

[0227] (3-1) Divide the first number of specified time units into the fifth number of time unit groups;

[0228] (3-2) Calculate the time interval between each time unit in each time unit group and the first DCI signaling, and assign a default beam indication information to the time unit whose time interval is less than a set threshold; assign one of the beam indication information in the fifth number of beam indication information to the time unit whose time interval is greater than or equal to the threshold, and assign different beam indication information in the fifth number of beam indication information to different time unit groups; wherein, the time unit group includes multiple consecutive time units and / or multiple discontinuous time units.

[0229] For example: the first quantity is K, the fifth quantity is 2, and the beam indication information to be assigned includes the first beam indication information and the second beam indication information; at this time, the K specified time units can be divided into two time unit groups, and the default beam indication information can be assigned to the time units in these two time unit groups whose time interval is less than a set threshold, and the first beam indication information can be assigned to the time units in the first time unit group whose time interval is greater than or equal to the threshold, and the second beam indication information can be assigned to the time units in the second time unit group whose time interval is greater than or equal to the threshold.

[0230] For example, if the first quantity is K and is even, and the fifth quantity is 2, when dividing the K specified time units into two time unit groups, the first K / 2 specified time units can be used as the first time unit group, and the last K / 2 specified time units can be used as the second time unit group; or, the first time unit group can be composed of odd-numbered specified time units such as the 1st, 3rd, 5th, 7th... and the second time unit group can be composed of even-numbered specified time units such as the 2nd, 4th, 6th, 8th... In other words, the first time unit group is an odd-numbered group, and the second time unit group is an even-numbered group.

[0231] For example: the first quantity is K, the fifth quantity is 1, and the beam indication information to be assigned includes the first beam indication information; at this time, the time interval between each specified time unit and the first DCI signaling is first calculated, and the default beam indication information is assigned to the specified time units whose time interval is less than a set threshold; the first beam indication information is assigned to the time units whose time interval is greater than or equal to the threshold.

[0232] Method 4: The number of beam indication information to be assigned is the sixth number, and the number of each specified time unit is the first number. The sixth number is less than the first number, and the sixth number is an integer greater than 0.

[0233] In this approach, step 510 may include:

[0234] (4-1) Calculate the time interval between each specified time unit and the first DCI signaling, and assign default beam indication information to the time units whose time interval is less than a set threshold;

[0235] (4-2) Divide the time units with time intervals greater than or equal to the threshold into the sixth number of time unit groups, and assign one of the beam indication information from the sixth number of beam indication information to each time unit group in the sixth number of time unit groups. Different time unit groups are assigned different beam indication information from the sixth number of beam indication information. The time unit group includes multiple consecutive time units and / or multiple discontinuous time units.

[0236] For example: the first quantity is K, the fifth quantity is 2, and the beam indication information to be assigned includes the first beam indication information and the second beam indication information; at this time, the default beam indication information can be assigned to the time units with time intervals less than the set threshold first, and then the time units with time intervals greater than or equal to the set threshold can be divided into the first time unit group and the second time unit group, and the first beam indication information can be assigned to the time units in the first time unit group and the second beam indication information can be assigned to the time units in the second time unit group.

[0237] The difference between Method 3 and Method 4 is that Method 3 groups the data first and then assigns the default beam indication information; Method 4 assigns the default beam indication information first and then groups the data.

[0238] In one embodiment, the beam indication information to be allocated in the above-mentioned methods one, two, three and four may include a TCI (Transmission Configuration Indication) state, which is used to indicate the beam information used by the terminal when receiving data; and / or spatial relation information, which is used to indicate the beam information used by the terminal when sending data.

[0239] In one embodiment, the default beam indication information in (2-1), (3-2) and (4-1) above includes the default TCI state and / or the default spatial relationship information.

[0240] In one embodiment, the default TCI state is the same as the TCI state used to receive 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), wherein the CORESET and the first DCI signaling come from the same antenna panel.

[0241] In one embodiment, the default spatial relationship information is the same as the spatial relationship information used to send the most recent PUCCH (Physical Uplink Control Channel), and the antenna panel used to send the PUCCH is the same as the antenna panel used to send the uplink data.

[0242] In step 520, beam indication information is added to the first DCI signaling.

[0243] In one embodiment, the first DCI signaling also needs to explicitly specify the antenna panel identifier corresponding to each designated time unit, so when performing step 520, it may include:

[0244] (5-1) Determine the antenna panel identifier corresponding to each specified time unit.

[0245] (5-2) Add the beam indication information and the antenna panel identifier to the first DCI signaling.

[0246] As can be seen from the above embodiments, beam indication information and / or antenna panel identifier corresponding to each specified time unit can be determined, and the beam indication information and / or antenna panel identifier can be added to the first DCI signaling. This facilitates the terminal to transmit TB according to the beam indication information and / or antenna panel identifier of the first DCI signaling, thereby improving the reliability of the terminal using beam when transmitting TB.

[0247] Figure 6 This is a flowchart illustrating a transmission indication method according to an exemplary embodiment. This transmission indication method can be used in a terminal, such as... Figure 6 As shown, the transmission indication method may include the following steps 610-620:

[0248] In step 610, a first DCI signaling is received from the base station, which instructs the transmission of one or more TBs over a first number of specified time units. The first number is an integer greater than 1.

[0249] In this embodiment of the disclosure, the base station can receive TB through the DCI signaling scheduling terminal or send TB through the scheduling terminal.

[0250] For example: the first quantity is K, and the first DCI signaling indicates that one TB should be transmitted over K specified time units. That is, the terminal needs to transmit the TB in each of the K specified time units.

[0251] For example, if the first quantity is K, the first DCI signaling indicates that two TBs will be transmitted over K specified time units, specifically the first TB and the second TB. That is, a portion of these K specified time units will transmit the first TB, and another portion will transmit the second TB.

[0252] For example, if the first quantity is K, the first DCI signaling indicates that K TBs will be transmitted over K specified time units. That is, each of these K specified time units will transmit one TB, and the number of TBs transmitted in each specified time unit will be different.

[0253] In step 620, TB is transmitted in each specified time unit according to the first DCI signaling.

[0254] In this embodiment of the disclosure, since the first DCI signaling includes different content, TB can be transmitted in each specified time unit according to these different contents, specifically including but not limited to the following situations:

[0255] Scenario 1: The specified time unit is a specified micro-time slot; the first DCI signaling includes the starting symbol position and symbol number of each specified micro-time slot.

[0256] In this case, when performing step 620, the starting symbol position and number of symbols for each specified micro-slot can be determined first according to the first DCI signaling; then the TB can be transmitted according to the starting symbol position and number of symbols for each specified micro-slot.

[0257] Scenario 2: The specified time unit is a specified time slot; the first DCI signaling includes the specified start symbol position and the specified end symbol position of each specified time slot.

[0258] In this case, when performing step 620, the specified start symbol position and specified end symbol position for transmitting the TB can be determined first according to the first DCI signaling; and then the TB can be transmitted according to the specified start symbol position and the specified end symbol position.

[0259] In one embodiment, the specified start symbol position is for the first specified time slot among the various specified time slots, while the start symbol position of the other specified time slots is the first symbol; or the specified start symbol position is for each specified time slot among the various specified time slots.

[0260] In one embodiment, the specified end symbol position is for the last specified time slot among the various specified time slots, while the end symbol position of the other specified time slots is the last symbol; or the specified end symbol position is for each specified time slot among the various specified time slots.

[0261] Scenario 3: The first DCI signaling includes beam indication information corresponding to each of the specified time units.

[0262] In this case, when performing step 620, the beam indication information corresponding to each specified time unit can be determined first according to the first DCI signaling; then the TB can be transmitted according to the beam indication information.

[0263] Scenario 4: The first DCI signaling includes beam indication information and antenna panel identification corresponding to each specified time unit.

[0264] In this case, when performing step 620, the beam indication information and antenna panel identifier corresponding to each specified time unit can be determined first according to the first DCI signaling; then the TB can be transmitted according to the beam indication information and the antenna panel identifier.

[0265] In one embodiment, the beam indication information in scenarios three and four above may include a TCI state, which indicates the beam information used by the terminal when receiving data; and / or spatial relationship information, which indicates the beam information used by the terminal when transmitting data.

[0266] As can be seen from the above embodiments, when receiving the first DCI signaling sent by the base station, the first DCI signaling is used to indicate the transmission of one or more TBs in a first number of specified time units. TBs can be transmitted in each specified time unit according to the first DCI signaling, thereby realizing the transmission of TBs in different time units using different beam directions through a single DCI indication, and also improving communication robustness.

[0267] Corresponding to the embodiments of the aforementioned transmission indication method, this disclosure also provides embodiments of a transmission indication device.

[0271] The sending module 73 is configured to send the first DCI signaling to the terminal so that the terminal transmits the TB in each of the specified time units according to the first DCI signaling.

[0272] As can be seen from the above embodiments, when it is determined that one or more TBs will be transmitted in a first number of specified time units, a first DCI signaling can be generated. The first DCI signaling is used to indicate the transmission of TBs in each specified time unit and to send the first DCI signaling to the terminal. In this way, after receiving the first DCI signaling, the terminal can transmit TBs in each specified time unit according to the first DCI signaling, thereby realizing the transmission of TBs in different time units using different beam directions through DCI indication, and also improving communication robustness.

[0284] In one embodiment, based on Figure 9 Based on the device shown, each of the specified time slots is an adjacent time slot.

[0285] As can be seen from the above embodiments, the specified start symbol position and specified end symbol position of each specified time slot can be determined, and the specified start symbol position and specified end symbol position can be added to the first DCI signaling. This makes it easier for the terminal to transmit TB according to the specified start symbol position and specified end symbol position of the first DCI signaling, thereby improving the efficiency of TB transmission.
