Description

[Technical field]

[0001] The present disclosure relates to the field of communications, and in particular to a method and apparatus for determining HARQ feedback delay, and a storage medium. [Background technology]

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

[0003] Here, the value k1 represents the feedback delay of the HARQ result, that is, the terminal receives a PDSCH in time unit n, and transmits the HARQ result corresponding to the PDSCH on the PUCCH in time unit (n+k1), which requires that the terminal can complete the demodulation of the PDSCH and the generation of the HARQ result information within k1 time units.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the drawings. Where the following description refers to the drawings, the same numerals in different drawings represent the same or similar elements unless otherwise stated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with embodiments of the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of embodiments of the present invention, as detailed in the appended claims.

[0036] The terms used in this disclosure are merely for the purpose of describing 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 "the" are also intended to include the plural forms unless the context clearly indicates otherwise. As used herein, the term "and / or" refers to any or all possible combinations of one or more of the associated listed items.

[0037] In this disclosure, terms such as first, second, third, etc. may be used to describe various information, but it should be understood that such information should not be limited to these terms. These terms are merely used to distinguish between the same types of information. For example, a first piece of information could be referred to as a second piece of information, and similarly, a second piece of information could be referred to as a first piece of information, without departing from the scope of this disclosure. Depending on the context, the word "if" as used herein can be interpreted as "when" or "in the case of" or "responsive to a determination."

[0038] In the embodiment of the present disclosure, the relevant DCI is a DCI of a preset format, where the preset format is a default format for scheduling PDSCH used by the base station, for example, the 1-0 format. The DCI of the 1-0 format can be used before establishing an RRC (Radio Resource Control) connection between the base station and the terminal. Because the RRC connection has not yet been established between the base station and the terminal, and the base station cannot inform the terminal of the possible value of the HARQ feedback delay k1 by the RRC parameter, the possible values ​​of the k1 set corresponding to the DCI of the 1-0 format usually need to be predefined in the protocol. In a low-band communication system below 52.6 GHz, for the DCI of the 1-0 format, the possible values ​​of the k1 set defined in the protocol include {1, 2, 3, 4, 5, 6, 7, 8}.

[0039] In a low-bandwidth communication system, the selectable SCS (SubCarrierSpacing) can be 15KHz (kilohertz), 30KHz, 60KHz, or 120KHz, and the time unit generally uses a slot. For a subcarrier bandwidth of 15KHz, the time length of one slot is 1ms (milliseconds), for a subcarrier bandwidth of 30KHz, the time length of one slot is 0.5ms, and for a subcarrier bandwidth of 60KHz, the time length of one slot is 0.25ms, which can be inferred from this. It can be seen that the larger the subcarrier bandwidth, the shorter the time length of one slot.

[0040] On the other hand, in a high-bandwidth communication protocol, the high-bandwidth in the embodiment of the present disclosure can refer to about 60 GHz (gigahertz). In order to deal with phase noise, a large SCS, for example, 960 KHz, is usually selected. When the SCS is 960 KHz, the time length of one slot is 0.015625 ms, that is, 1 / 64 ms.

[0041] In a high-bandwidth communication system, when 960KHz is used for SCS, it can be seen that the time length of one slot is much less than 1ms. When DCI uses the 1-0 format, k1 defined in the current standard is a value selected from the set {1, 2, 3, 4, 5, 6, 7, 8}. That is, the maximum value of k1 is 8, or 0.125ms. If the time length of one slot is much less than 1ms, it is difficult for the terminal to complete PDSCH demodulation and HARQ result generation.

[0042] The present disclosure provides a method for determining a HARQ feedback delay to be provided in a high-bandwidth communication system when the time length of one slot is much less than 1 ms.

[0043] Hereinafter, first, from the base station side, the method for determining the HARQ feedback delay provided by the present disclosure will be described.

[0044] An embodiment of the present disclosure provides a method for determining a HARQ feedback delay, and the method is applied to a base station. Referring to FIG. 1, FIG. 1 is a flowchart of a method for determining a HARQ feedback delay shown by an embodiment, and the method can include the following steps 101 to 102.

[0045] In step 101, a target HARQ feedback delay set is determined from among a plurality of HARQ feedback delay sets corresponding to downlink control information (DCI) of a preset format predefined in a protocol.

[0046] In the embodiment of the present disclosure, the predefined format refers to the 1-0 format, and multiple HARQ feedback delay sets corresponding to the DCI of the 1-0 format can be predefined in the protocol, and the multiple HARQ feedback delay sets correspond to different subcarrier bandwidths. For example, the SCS of 240KHz corresponds to HARQ feedback delay set 1, the SCS of 480KHz corresponds to HARQ feedback delay set 2, the SCS of 960KHz corresponds to HARQ feedback delay set 3, etc.

[0047] The base station may select one HARQ feedback delay set from the plurality of HARQ feedback delay sets as a target HARQ feedback delay set.

[0048] In step 102, a DCI in the preset format for indicating a target delay value is transmitted to a terminal.

[0049] In the embodiment of the present disclosure, the target HARQ feedback delay set includes multiple delay values, and the base station can select one delay value as a target delay value for the terminal based on the current business needs of the terminal. Furthermore, the base station can send a DCI of a preset format to the terminal to indicate the target delay value. Then, the terminal side determines the target delay value based on the DCI of the preset format.

[0050] In the above embodiment, the base station may select one HARQ feedback delay set as a target HARQ feedback delay set from among a plurality of HARQ feedback delay sets corresponding to DCI of a preset format predefined in a protocol, where the plurality of HARQ feedback delay sets correspond to different subcarrier bandwidths. Furthermore, the base station enables the terminal to determine the target delay value by transmitting the DCI of the preset format for indicating the target delay value, where the target delay value is one of a plurality of delay values ​​included in the target HARQ feedback delay set. The present disclosure achieves the objective of determining a HARQ feedback delay for a case where one time unit is much less than 1 ms in a high-bandwidth communication system.

[0051] In one alternative embodiment, multiple HARQ feedback delay sets predefined in the protocol correspond to different subcarrier bandwidths.

[0052] Here, the larger the SCS, the smaller the time length of one slot. Therefore, in order to ensure that the terminal can complete PDSCH demodulation and HARQ feedback result generation within the time unit corresponding to the delay value, 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 may be.

[0053] For example, the subcarrier bandwidth is 240KHz, and the corresponding maximum delay value of HARQ feedback delay set 1 is m1, the subcarrier bandwidth is 480KHz, and the corresponding maximum delay value of HARQ feedback delay set 2 is m2, the subcarrier bandwidth is 960KHz, and the corresponding maximum delay value of HARQ feedback delay set 3 is m3, etc., where m1 <m2<m3<···。

[0054] Specifically, possible values ​​of the HARQ feedback delay set are, for example, as shown below:

[0055] For example, for an SCS of 120KHz and below, the possible values ​​of the HARQ feedback delay set include {1, 2, 3, 4, 5, 6, 7, 8}, and for an SCS of 240KHz and above, the possible values ​​of the HARQ feedback delay set include {4, 6, 8, 10, 12, 14, 16}.

[0056] For example, for an SCS of 240KHz and below, the possible values ​​of the HARQ feedback delay set include {1, 2, 3, 4, 5, 6, 7, 8}; for an SCS of 480KHz and below, the possible values ​​of the HARQ feedback delay set include {5, 6, 7, 8, 9, 10, 11, 12}; and for an SCS of 960KHz and below, the possible values ​​of the HARQ feedback delay set include {4, 8, 12, 16, 20, 24, 28, 32}.

[0057] The above are merely examples, and the HARQ feedback delay sets actually defined in the standard are not limited to the above possible combinations of values.

[0058] According to the currently adopted subcarrier bandwidth, the base station can determine the HARQ feedback delay set corresponding to the currently adopted subcarrier bandwidth as the target HARQ feedback delay set. For example, if the currently adopted subcarrier bandwidth is 480KHz, the corresponding HARQ feedback delay set 2 can be the target HARQ feedback delay set.

[0059] In the above embodiment, the HARQ feedback delay set corresponding to the currently adopted subcarrier bandwidth may be 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 in a high-bandwidth communication system, a terminal can complete demodulation of PDSCH and generate HARQ feedback result in a time unit corresponding to the target delay value, and the purpose of determining HARQ feedback delay in a high-bandwidth communication system is realized.

[0060] In one embodiment, referring to FIG. 2, FIG. 2 is a flowchart of another HARQ feedback delay determination method according to the embodiment shown in FIG. 1, and after step 102, the method may include steps 103-105.

[0061] In step 103, the number of bits occupied by the specific information field in the DCI of the pre-configured format is determined based on the total number of delay values ​​included in the target HARQ feedback delay set pre-defined in a protocol.

[0062] Here, the specific information field is an information field for indicating the target delay value in the DCI, and the number of bits occupied by the specific information field can be determined based on the total number of delay values ​​included in the target HARQ feedback delay set predefined in a protocol.

[0063] 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 specific information field is

number

number

[0064] In step 104, an order value of the target delay value in the target HARQ feedback delay set is determined.

[0065] In an embodiment of the present disclosure, an order value of a target delay value in the target HARQ feedback delay set can be determined first, where the order value can be increased sequentially starting from 0. For example, the possible values ​​of the target HARQ feedback delay set include {5, 6, 7, 8, 9, 10, 11, 12}, and when the target delay value is 8, the corresponding order value is 3.

[0066] In step 105, the bit value of the specific information field occupying said number of bits is set equal to said sequence value.

[0067] For example, the designated information field occupies three bits. The target delay value is 8, and the corresponding order value is 3, represented by the bit value of the designated information field occupying three bits, the bit value can be 011.

[0068] Accordingly, step 103 includes sending a DCI in a preset format to the terminal, where the specific information field in the DCI occupies three bits and the bit value is 011.

[0069] In the above embodiment, the number of bits occupied by a specific information field in DCI of a preset format can be determined based on the total number of delay values ​​included in a target HARQ feedback delay set predefined in a protocol. Here, the specific information field is an information field for indicating the target delay value in the DCI. Also, the bit value of the specific information field occupying the number of bits can be determined based on the target delay value. This achieves the objective of transmitting a target delay value to a terminal through a specific information field of DCI of a preset format in a high-bandwidth communication system.

[0070] The following describes, from the terminal side, the method for determining the HARQ feedback delay provided by the present disclosure.

[0071] An embodiment of the present disclosure provides another HARQ feedback delay determination method applied to a terminal. Referring to FIG. 3, FIG. 3 is a flowchart of another HARQ feedback delay determination method shown by an embodiment, which may include the following steps 201-202.

[0072] In step 201, downlink control information (DCI) in a pre-configured format transmitted from a base station is received.

[0073] In an embodiment of the present disclosure, the pre-configured format is a default format, such as the 1-0 format, used by the base station for scheduling the PDSCH.

[0074] In step 202, a target delay value for performing HARQ feedback is determined based on the DCI of the preset format.

[0075] In an embodiment of the present disclosure, the DCI of a preset format includes a specification information field for indicating a target delay value, and the terminal side can determine the target delay value based on the specification information field.

[0076] In the above embodiment, the terminal receives downlink control information (DCI) of a preset format transmitted from the base station, and can determine a target delay value for performing HARQ feedback according to the DCI of the preset format, thereby realizing the purpose of determining a HARQ feedback delay in a high-bandwidth communication system.

[0077] In one optional embodiment, referring to FIG. 4, FIG. 4 is a flowchart of another HARQ feedback delay determination method according to the embodiment shown in FIG. 3, where step 202 may include steps 202-1 to 202-4.

[0078] In step 202-1, a target HARQ feedback delay set is determined from among a plurality of HARQ feedback delay sets corresponding to downlink control information (DCI) of a preset format predefined in a protocol.

[0079] In the embodiment of the present disclosure, multiple HARQ feedback delay sets predefined in the protocol can correspond to different subcarrier bandwidths. The HARQ feedback delay set corresponding to the currently adopted subcarrier bandwidth can be 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, so as to ensure that the terminal side demodulates the PDSCH and generates the HARQ feedback result in the time domain unit corresponding to the target delay value.

[0080] In step 202-2, the number of bits occupied by the designated information field in the DCI of the pre-configured format is determined based on the total number of delay values ​​included in the target HARQ feedback delay set pre-defined in a protocol.

[0081] Here, the specific information field is an information field for indicating the target delay value in the DCI. The total number of delay values ​​included in the target HARQ feedback delay set is predefined in the protocol, and assuming that the total number is N, the terminal determines that the number of bits occupied by the specific information field in the DCI of the predefined format is N.

number

[0082] Step 202-3 determines the bit values ​​of said specific information field occupying said number of bits.

[0083] In the embodiment of the present disclosure,

number

[0084] In step 202-4, the delay value in the target HARQ feedback delay set whose ordinal value is equal to the bit value is set as the target delay value.

[0085] In an embodiment of the present disclosure, the order values ​​in the target HARQ feedback delay set may be sorted from 0 and increased sequentially. When the target HARQ feedback delay set is known and the order values ​​in the target HARQ feedback delay set of the target delay values ​​are known, the target delay values ​​may be determined.

[0086] In one optional embodiment, refer to FIG. 5, which is a flowchart of another HARQ feedback delay determination method according to the embodiment shown in FIG. 3, and after step 202, the method may further include steps 203-205.

[0087] In step 203, a time domain unit for receiving the DCI of the preset format is determined.

[0088] In the embodiment of the present disclosure, a time domain unit in which DCI of a preset format is received may be determined, where the time domain unit may be, but is not limited to, a slot, etc.

[0089] In step 204, the sum of the number of time domain units receiving the DCI in the preset format and the target delay value is determined.

[0090] In an embodiment of the present disclosure, assuming that the number of time domain units receiving the DCI of the preset format is n and the target delay value is k1, the sum value is (n+k1).

[0091] In step 205, the time domain unit indicated by the sum value is set as the target time domain unit for performing HARQ feedback for the PDSCH scheduled by the DCI of the preset format.

[0092] In the embodiment of the present disclosure, the DCI of 1-0 format is used to schedule a PDSCH, and the terminal takes the time domain unit indicated by the sum value as a target time domain unit, and can feedback HARQ result for the PDSCH scheduled by the DCI in the target time domain unit.

[0100] In step 304, the base station sets a bit value of the specific information field occupying said number of bits equal to said sequence value.

[0101] In step 305, the base station transmits DCI in the preset format for indicating a target delay value to a terminal.

[0102] In step 306, after the terminal receives DCI of the preset format, a HARQ feedback delay set corresponding to a currently adopted subcarrier bandwidth among the plurality of HARQ feedback delay sets is set as the target HARQ feedback delay set.

[0103] In step 307, the terminal determines the number of bits occupied by the designated information field in the DCI of the pre-configured format based on the total number of delay values ​​included in the target HARQ feedback delay set pre-defined in a protocol.

[0104] In step 308, the terminal determines the bit values ​​of the specific information field that occupy the number of bits.

[0105] In step 309, the terminal sets a delay value in the target HARQ feedback delay set whose order value is equal to the bit value as the target delay value.

[0106] In step 310, the terminal determines a time domain unit in which to receive DCI of the preset format.

[0107] In step 311, the terminal determines the sum of the number of a time domain unit in which the terminal receives DCI in the preset format and the target delay value.

[0108] In step 312, the terminal determines the time domain unit indicated by the sum value as a target time domain unit for performing HARQ feedback for a PDSCH scheduled by DCI of the preset format.

[0109] In the above embodiment, it is possible to ensure that in a wideband communication system, a terminal can complete demodulation of a PDSCH and generation of a HARQ feedback result within a time unit corresponding to a target delay value, and the purpose of determining a HARQ feedback delay in the wideband communication system is realized.
