[0002] In the 5G (5th generation mobile networks) NR (New Radio) protocol, the base station schedules downlink data through DCI (Downlink Control Information) to transmit the downlink data on the PDSCH (Physical Downlink Shared Channel) in time unit n, and instructs the terminal in the DCI to use the PUCCH (Physical Uplink Control Channel) in time unit (n+k1) to feedback the HARQ (Hybrid Automatic Repeat reQuest) result for the downlink data transmitted in time unit n.

[0092] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0093] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0094] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0095] In the embodiments of the present disclosure, the DCI involved is a DCI in a preset format, wherein the preset format is a default format used by the base station for scheduling PDSCH, such as a 1-0 format. The 1-0 format DCI can be used before an RRC (Radio Resource Control) connection is established between the base station and the terminal. Since an RRC connection has not yet been established between the base station and the terminal, the base station cannot inform the terminal of the value of the HARQ feedback delay k1 through the RRC parameters. Therefore, the value of the k1 set corresponding to the 1-0 format DCI generally needs to be defined in advance in the protocol. In low-frequency band communication systems below 52.6 GHz, for the 1-0 format DCI, the values ​​of the k1 set defined in the protocol include {1, 2, 3, 4, 5, 6, 7, 8}.

[0096] In low-frequency band communication systems, the optional SCS (Subcarrier Spacing) can be 15 kHz, 30 kHz, 60 kHz, or 120 kHz, and the time unit is generally a slot. In the case of a 15 kHz subcarrier bandwidth, the duration of a slot is 1 ms (millisecond), in the case of a 30 kHz subcarrier bandwidth, the duration of a slot is 0.5 ms, in the case of a 60 kHz subcarrier bandwidth, the duration of a slot is 0.25 ms, and so on. It can be seen that the larger the subcarrier bandwidth, the shorter the slot duration.

[0097] In high-frequency communication protocols, which in the present disclosure may refer to approximately 60 GHz (gigahertz), a larger SCS, such as 960 kHz, is typically selected to mitigate phase noise. When the SCS is 960 kHz, the duration of a slot is 0.015625 ms, or 1 / 64 ms.

[0098] As can be seen, in high-band communication systems, when SCS uses 960 kHz, the duration of a slot is significantly less than 1 ms. When DCI uses the 1-0 format, the current standard specifies k1 as a value selected from the set {1, 2, 3, 4, 5, 6, 7, 8}. The maximum value of k1 is 8, or 0.125 ms. When a slot duration is significantly less than 1 ms, it is difficult for the terminal to complete PDSCH demodulation and generate HARQ results.

[0099] The present disclosure provides a solution for determining HARQ feedback delay in a high-frequency band communication system where the duration of a slot is much less than 1ms.

[0100] The following first introduces the method for determining HARQ feedback delay provided by the present disclosure from the base station side.

[0101] The embodiment of the present disclosure provides a method for determining HARQ feedback delay, which is used by a base station. Figure 1 As shown, Figure 1 This is a flow chart of a method for determining HARQ feedback delay according to an embodiment. The method may include the following steps:

[0102] In step 101, a target HARQ feedback delay set is determined from a plurality of HARQ feedback delay sets predefined in a protocol and corresponding to downlink control information DCI in a preset format.

[0103] In the disclosed embodiments, the preset format refers to the 1-0 format. Multiple HARQ feedback delay sets corresponding to the 1-0 format DCI may be predefined in the protocol. These multiple HARQ feedback delay sets correspond to different subcarrier bandwidths. For example, a 240 kHz SCS corresponds to HARQ feedback delay set 1, a 480 kHz SCS corresponds to HARQ feedback delay set 2, a 960 kHz SCS corresponds to HARQ feedback delay set 3, and so on.

[0104] The base station may select one from the multiple HARQ feedback delay sets as the target HARQ feedback delay set.

[0105] In step 102, a DCI in the preset format for indicating a target delay value is sent to a terminal.

[0106] In the disclosed embodiments, the target HARQ feedback delay set includes multiple delay values. The base station may select one target delay value for the terminal based on the current service requirements of the terminal. Furthermore, the base station may send a DCI in a preset format to the terminal indicating the target delay value. The terminal then determines the target delay value based on the DCI in the preset format.

[0107] In the above embodiment, the base station can select one as a target HARQ feedback delay set from a plurality of HARQ feedback delay sets pre-defined in the protocol and corresponding to DCI of a preset format. The plurality of HARQ feedback delay sets correspond to different subcarrier bandwidths. Furthermore, the base station sends the DCI of the preset format for indicating the target delay value to the terminal, so that the terminal can determine the target delay value. The target delay value is one of the plurality of delay values ​​included in the target HARQ feedback delay set. The present disclosure achieves the purpose of determining the HARQ feedback delay for a situation where a time unit is much less than 1ms in a high frequency band communication system.

[0108] In an optional embodiment, multiple HARQ feedback delay sets predefined in the protocol correspond to different subcarrier bandwidths.

[0109] Among them, since the larger the SCS, the shorter the duration of a slot, in order to ensure that the terminal can complete the demodulation of PDSCH and generate HARQ feedback results within the time unit corresponding to the delay value, in multiple HARQ feedback delay sets, the larger the subcarrier bandwidth, the larger the maximum delay value in the corresponding HARQ feedback delay set can be.

[0110] For example, if the subcarrier bandwidth is 240KHz, the corresponding HARQ feedback delay set 1 has a maximum delay value of m1; if the subcarrier bandwidth is 480KHz, the corresponding HARQ feedback delay set 2 has a maximum delay value of m2; if the subcarrier bandwidth is 960KHz, the corresponding HARQ feedback delay set 3 has a maximum delay value of m3, etc. Among them, m1 <m2<m3<……。

[0111] Specifically, the value of the HARQ feedback delay set may be, for example, as shown below:

[0112] For example, in the case of SCS of 120KHz and below, the values ​​of the HARQ feedback delay set include {1, 2, 3, 4, 5, 6, 7, 8}, and in the case of SCS of 240KHz and above, the values ​​of the HARQ feedback delay set include {4, 6, 8, 10, 12, 14, 16}.

[0113] For another example, in the case of SCS of 240KHz and below, the values ​​of the HARQ feedback delay set include {1, 2, 3, 4, 5, 6, 7, 8}; in the case of SCS of 480KHz and below, the values ​​of the HARQ feedback delay set include {5, 6, 7, 8, 9, 10, 11, 12}; in the case of SCS of 960KHz and below, the values ​​of the HARQ feedback delay set include {4, 8, 12, 16, 20, 24, 28, 32}.

[0114] The above is only an example, and the HARQ feedback delay set actually defined in the standard is not limited to the above value combinations.

[0115] The base station may determine, based on the currently used subcarrier bandwidth, a HARQ feedback delay set corresponding to the currently used subcarrier bandwidth as the target HARQ feedback delay set. For example, if the currently used subcarrier bandwidth is 480 kHz, the corresponding HARQ feedback delay set 2 may be used as the target HARQ feedback delay set.

[0116] In the above embodiment, the HARQ feedback delay set corresponding to the currently used subcarrier bandwidth can be used as the target HARQ feedback delay set. Optionally, among the multiple HARQ feedback delay sets predefined in the protocol, the larger the subcarrier bandwidth, the larger the maximum delay value in the corresponding HARQ feedback delay set. The present disclosure can ensure that the terminal can complete the demodulation of the PDSCH and generate the HARQ feedback result within the time unit corresponding to the target delay value in a high-frequency band communication system, thereby achieving the purpose of determining the HARQ feedback delay in a high-frequency band communication system.

[0117] In one embodiment, referring to Figure 2 As shown, Figure 2 is based on Figure 1 The embodiment shown is a flowchart of another method for determining HARQ feedback delay. After step 102, the method may further include:

[0118] In step 103, the number of bits occupied by the designated information field in the DCI of the preset format is determined according to the total number of delay values ​​included in the target HARQ feedback delay set predefined in the protocol.

[0119] The designated information field is an information field in the DCI used to indicate the target delay value. The number of bits occupied by the designated information field can be determined according to the total number of delay values ​​included in the target HARQ feedback delay set predefined in the protocol.

[0120] In the embodiment of the present disclosure, assuming that the total number of delay values ​​included in the target HARQ feedback delay set is N, the number of bits occupied by the specified information field is in, Indicates a round-up calculation. The value of N can be 8, 16, etc., which is pre-agreed in the protocol and is not limited in this disclosure. For example, when the value of N is 8, the number of bits occupied by the designated information field is 3.

[0121] In step 104, the order value of the target delay value in the target HARQ feedback delay set is determined.

[0122] In an embodiment of the present disclosure, the target delay value may be first determined as an order value within the target HARQ feedback delay set. The order value may start at 0 and increase in sequence. For example, if the target HARQ feedback delay set includes {5, 6, 7, 8, 9, 10, 11, 12} and the target delay value is 8, the corresponding order value is 3.

[0123] In step 105, the bit value of the designated information field occupying the number of bits is set to be equal to the sequence value.

[0124] For example, the designated information field occupies 3 bits. The target delay value is 8, and the corresponding sequence value is 3, which is represented by the bit value of the designated information field that occupies 3 bits. The bit value can be 011.

[0125] Accordingly, step 103 may include: sending a DCI in a preset format to the terminal, wherein the designated information field in the DCI occupies 3 bits, and the bit values ​​are 011.

[0126] In the above embodiment, the number of bits occupied by the designated information field in the preset format DCI can be determined based on the total number of delay values ​​included in the target HARQ feedback delay set predefined in the protocol. The designated information field is an information field in the DCI used to indicate the target delay value. Furthermore, the bit value of the designated information field that occupies the number of bits can also be determined based on the target delay value. This achieves the purpose of sending the target delay value to the terminal via the designated information field of the preset format DCI in a high-frequency band communication system.

[0127] Next, the method for determining the HARQ feedback delay provided by the present disclosure is introduced from the terminal side.

[0128] The embodiment of the present disclosure provides another method for determining HARQ feedback delay, which is used by a terminal. Figure 3 As shown, Figure 3 This is a flow chart showing another method for determining HARQ feedback delay according to an embodiment. The method may include the following steps:

[0129] In step 201, downlink control information DCI in a preset format sent by a base station is received.

[0130] In the embodiment of the present disclosure, the preset format is a default format used by the base station for scheduling PDSCH, such as a 1-0 format.

[0131] In step 202, a target delay value for HARQ feedback is determined according to the DCI in the preset format.

[0132] In the embodiment of the present disclosure, a DCI in a preset format includes a designated information field for indicating a target delay value, and the terminal side can determine the target delay value according to the designated information field.

[0133] In the above embodiment, the terminal can receive downlink control information DCI in a preset format sent by the base station, and thereby determine the target delay value for HARQ feedback based on the DCI in the preset format, thereby achieving the purpose of determining HARQ feedback delay in a high-frequency band communication system.

[0134] In an alternative embodiment, referring to Figure 4 As shown, Figure 4 is based on Figure 3 The embodiment shown is a flowchart of another method for determining HARQ feedback delay. Step 202 may include:

[0135] In step 202-1, a target HARQ feedback delay set is determined from a plurality of HARQ feedback delay sets predefined in the protocol and corresponding to downlink control information DCI in a preset format.

[0136] In the disclosed embodiments, multiple HARQ feedback delay sets predefined in the protocol may correspond to different subcarrier bandwidths. The HARQ feedback delay set corresponding to the currently used subcarrier bandwidth may be used as the target HARQ feedback delay set. Similarly, among the multiple HARQ feedback delay sets, the larger the subcarrier bandwidth, the larger the maximum delay value in the corresponding HARQ feedback delay set, ensuring that the terminal side can demodulate the PDSCH and generate HARQ feedback results within the time domain unit corresponding to the target delay value.

[0137] In step 202-2, the number of bits occupied by the designated information field in the DCI of the preset format is determined according to the total number of delay values ​​included in the target HARQ feedback delay set predefined in the protocol.

[0141] In step 202-4, in the target HARQ feedback delay set, a delay value having an order value equal to the bit value is used as the target delay value.

[0142] In the embodiment of the present disclosure, the order values ​​in the target HARQ feedback delay set may be sorted starting from 0 and increasing in sequence. If the target HARQ feedback delay set is known and the order value of the target delay value in the target HARQ feedback delay set is known, the target delay value may be determined.

[0146] In step 204, the sum of the sequence number of the time domain unit receiving the DCI in the preset format and the target delay value is determined.

[0147] In the embodiment of the present disclosure, assuming that the sequence number of the time domain unit for receiving the DCI in the preset format is n and the target delay value is k1, the sum value is (n+k1).

[0148] In step 205, the time domain unit indicated by the sum value is used as the target time domain unit for HARQ feedback for the PDSCH scheduled by the DCI of the preset format.

[0149] In the disclosed embodiment, a 1-0 format DCI is used to schedule a PDSCH. The terminal may use the time domain unit indicated by the sum value as the target time domain unit and provide HARQ feedback for the PDSCH scheduled by the DCI in the target time domain unit. For example, feedback may be provided on whether the downlink data on the PDSCH is successfully received. If successful, an ACK may be provided; if unsuccessful, a NACK may be provided.

[0154] In step 302, the base station determines the number of bits occupied by the designated information field in the DCI of the preset format according to the total number of delay values ​​included in the target HARQ feedback delay set predefined in the protocol.

[0155] The designated information field is an information field in the DCI used to indicate a target delay value, and the target delay value is one of multiple delay values ​​included in a target HARQ feedback set.

[0156] In step 303, the base station determines the order value of the target delay value in the target HARQ feedback delay set.

[0157] In step 304, the base station sets the bit value of the designated information field occupying the number of bits to be equal to the sequence value.

[0158] In step 305, the base station sends the DCI in the preset format for indicating the target delay value to the terminal.

[0159] In step 306, after receiving the DCI in the preset format, the terminal uses the HARQ feedback delay set corresponding to the currently used subcarrier bandwidth among the multiple HARQ feedback delay sets as the target HARQ feedback delay set.

[0160] In step 307, the terminal determines the number of bits occupied by the designated information field in the DCI of the preset format according to the total number of delay values ​​included in the target HARQ feedback delay set predefined in the protocol.

[0161] In step 308, the terminal determines the bit value of the designated information field occupying the number of bits.

[0162] In step 309, the terminal uses the delay value with the same sequence value as the bit value in the target HARQ feedback delay set as the target delay value.

[0163] In step 310, the terminal determines a time domain unit for receiving the DCI in the preset format.

[0164] In step 311, the terminal determines the sum of the sequence number of the time domain unit for receiving the DCI in the preset format and the target delay value.

[0165] In step 312, the terminal uses the time domain unit indicated by the sum value as the target time domain unit for HARQ feedback for the PDSCH scheduled by the DCI of the preset format.

[0166] In the above embodiment, in a high frequency band communication system, it can be ensured that the terminal can complete the demodulation of PDSCH and generate HARQ feedback results within the delay unit corresponding to the target delay value, thereby achieving the purpose of determining the HARQ feedback delay in the high frequency band communication system.
