[0017] The following describes in detail the technical solutions according to the embodiments of the present application through specific embodiments and application scenarios in conjunction with the drawings.

[0018] As shown in FIG. 2, a flowchart of a communication processing method 200 according to an exemplary embodiment of the present application is shown, where the method 200 can be applied to a communication device (e.g., a terminal, a network device, etc.) and can be specifically executed by hardware and / or software installed in the communication device.

[0019] The method 200 may include the following steps.

[0020] In S210, a predetermined operation is performed based on the transmission time of the target PDSCH.

[0021] Here, the target PDSCH is configured without target HARQ-ACK information feedback, for example, the target PDSCH adopts or configures a HARQ-ACK disabling scheme, where the HARQ-ACK disabling scheme is used to reduce feedback load. For example, assuming that the target PDSCH is an SPS PDSCH, when a HARQ-ACK disabling scheme is configured for the SPS PDSCH, SPS PDSCH transmission does not need to feed back HARQ-ACK information, but can ensure that the corresponding SPS PDSCH can be accurately transmitted when a network device configures transmission resources and attributes to activate the SPS PDSCH.

[0022] Or, there is a feedback delay in the target HARQ-ACK information corresponding to the target PDSCH. For example, in a Time Division Duplex (TDD) system, the SPS HARQ-ACK corresponding to the target PDSCH cannot be fed back at a predefined feedback position due to a directional collision of the transmission resource at the predefined feedback position, so the feedback needs to be delayed.

[0023] In this embodiment, the target PDSCH may be an SPS PDSCH, etc. Accordingly, the target HARQ-ACK information may be SPS HARQ-ACK information corresponding to an SPS PDSCH, and in some circumstances, the target PDSCH may be a dynamically scheduled PDSCH, or the target PDSCH may further be deployed to a target Physical Uplink Shared Channel (PUSCH), for example, a Configured Grant (CG) PUSCH, at this time, the target HARQ-ACK information may correspond to a PUSCH and is sent to the terminal by a network device, for example, the target HARQ-ACK information may correspond to a Configured Grant downlink feedback information (CG-DFI) in NR-U, and in this embodiment, there is no limitation here.

[0024] It should be noted that, for convenience of description, in the following embodiments, when a HARQ-ACK disabling scheme is configured in an SPS configuration (SPS Config) of the target PDSCH, the corresponding SPS PDSCH may be hereinafter referred to as an SPS PDSCH without feedback, and an SPS PDSCH corresponding to another SPS Config (where HARQ-ACK disabling is not configured) is hereinafter referred to as a normal SPS PDSCH, and the SPS PDSCH described below generally refers to SPS PDSCH transmission corresponding to an SPS Config, including an SPS PDSCH without feedback and a normal SPS PDSCH.

[0025] Furthermore, the predetermined operation may include at least one of the following (1) to (5).

[0026] (1) Determine whether the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit.

[0027] Here, taking the SPS PDSCH as an example, it may be understood that when it is necessary to use the HARQ-ACK feedback time or HARQ-ACK feedback time unit of the SPS PDSCH, the nominal HARQ-ACK feedback time unit may use this nominal HARQ-ACK feedback time unit or a time corresponding to this nominal HARQ-ACK feedback time unit (i.e., the nominal HARQ-ACK feedback time, for example, the time corresponding to the nominal HARQ-ACK feedback time unit may be the end time of this time unit), and subsequent functions or processes of the HARQ-ACK feedback time or HARQ-ACK feedback time unit depending on the SPS PDSCH can be performed smoothly.

[0028] Although the SPS PDSCH without feedback (i.e., the SPS PDSCH corresponding to the SPS Config configured without HARQ-ACK information feedback) is configured so as not to require HARQ-ACK feedback at higher layers, each SPS PDSCH without feedback may still have a corresponding HARQ-ACK feedback time, i.e., a nominal HARQ-ACK feedback time, or a nominal HARQ-ACK feedback time unit, and of course, each SPS PDSCH without feedback may not have a corresponding nominal HARQ-ACK feedback time unit.

[0029] Alternatively, if there is a nominal HARQ-ACK feedback time unit corresponding to a feedback-less SPS PDSCH, at this nominal HARQ-ACK feedback time unit or nominal HARQ-ACK feedback time (e.g., the nominal HARQ-ACK feedback time unit is determined based on the end time of the nominal HARQ-ACK feedback time unit), the feedback-less SPS PDSCH, i.e., the target PDSCH, may be considered to have confirmed successful transmission, so the nominal HARQ-ACK feedback time unit or the nominal HARQ-ACK feedback time may be the successful transmission time of the target PDSCH.

[0030] For an SPS PDSCH in which a feedback delay exists in the corresponding HARQ-ACK information (e.g., in a TDD system, a resource at a predefined feedback time position is not available, so a feedback delay exists in the HARQ-ACK information of this SPS PDSCH), a concept of a nominal HARQ-ACK feedback time unit or a nominal HARQ-ACK feedback time may be introduced. In this case, the nominal HARQ-ACK feedback time unit or the nominal HARQ-ACK feedback time may be determined based on a predefined / pre-indicated feedback time unit / feedback time, or may be determined based on other manners.

[0031] (2) Determine the activation time of the target medium access control-layer control unit (MAC CE).

[0032] Here, the target MAC CE is carried on the target PDSCH. In NR, a MAC CE-based indication method is introduced for several functions, which corresponds to L2 signaling. In this embodiment, the activation time of the target MAC CE is determined based on the transmission time of the target PDSCH, so that the problem of the HARQ-ACK feedback time being unavailable or ambiguous when the activation time of the target MAC CE is determined based on the HARQ-ACK feedback time can be avoided or solved, and the normal execution of this function or process (i.e., the activation time of the MAC CE is clearly defined, and the understanding of the network side and the terminal side is consistent) is ensured based on the MAC CE. As can be seen, the target MAC CE carried on the target PDSCH is a downlink MAC CE. When this embodiment is deployed in a PUSCH, the target MAC CE may be an uplink MAC CE accordingly.

[0033] (3) Determine a target HARQ-ACK codebook corresponding to the target PDSCH.

[0034] Generally, SPS PDSCH transmission without feedback has no corresponding HARQ-ACK feedback bit or no corresponding HARQ-ACK codebook. However, in NR Rel-15 / 16, there are several HARQ-ACK Codebook types. In order to avoid inconsistency in the understanding of the Codebook size (i.e., the length of the HARQ-ACK bit sequence corresponding to the codebook) between both sides (i.e., the terminal and the network device) due to DCI detection failure, etc., a semi-statically configured Codebook size is adopted. At this time, the Codebook size does not depend on the downlink data scheduling or transmission situation, and there may still be HARQ-ACK bits corresponding to SPS PDSCH transmission without feedback in the Codebook. The setting of these HARQ-ACK bits at the transmitting side and the understanding at the receiving side require corresponding provisions. These HARQ-ACK codebook types may refer to the second type of HARQ-ACK codebook mentioned in the subsequent embodiment. In addition, there are several other HARQ-ACK codebook types, in which the settings of HARQ-ACK bits and values ​​depend on downlink data scheduling or transmission conditions, and these HARQ-ACK codebook types may refer to the first type of HARQ-ACK codebook mentioned in subsequent embodiments.

[0035] For the different HARQ-ACK codebook types mentioned above, the correspondence between the SPS PDSCH transmission without feedback (which can be a kind of situation of the target PDSCH) and a specific codebook (which can be understood as a target HARQ-ACK codebook) corresponding to a certain HARQ-ACK codebook type, and the setting of the HARQ-ACK bit in this specific codebook, requires a corresponding rule, so as to ensure the consistency of the understanding on both sides. In this embodiment, the target HARQ-ACK codebook can be determined based on the transmission time of the target PDSCH, so as to ensure the consistency of the understanding on both sides of the correspondence between the PDSCH and the HARQ-ACK codebook, and the setting of the HARQ-ACK bit in the HARQ-ACK codebook.

[0036] (4) Determine the application of the first rule.

[0037] Here, the first rule represents a timing relationship requirement between the target PDSCH and the feedback time corresponding to the target HARQ-ACK information, for example, the HARQ-ACK feedback of the PDSCH that is required to start transmission early should not be later than the HARQ-ACK feedback of the PDSCH that starts transmission late, thereby ensuring that the terminal side can perform operations such as receiving scheduling downlink control information (DCI), receiving PDSCH and feedback HARQ-ACK in a pipeline manner, avoiding out-of-order and reducing the implementation complexity of the terminal. It should be understood that the first rule may also be understood as an out-of-order rule, or an OoO rule, or an order guarantee rule, or an order avoidance rule.

[0038] In this embodiment, the application of the first rule is determined according to the transmission time of the target PDSCH, ensuring that the terminal and the network side have consistent understanding of restrictions on operations such as DCI scheduling reception, PDSCH reception and HARQ-ACK feedback, ensuring the smooth execution of downlink PDSCH transmission and HARQ-ACK feedback, and thereby ensuring the transmission performance of downlink data.

[0039] (5) Determines whether the target Discontinuous Reception (DRX) timer is started.

[0040] Here, the target DRX timer corresponds to a first HARQ process, and the first HARQ process corresponds to the target PDSCH.

[0041] For SPS PDSCH without feedback, when the upper layer configures the HARQ-ACK disabling scheme, it is assumed or expected that the transmission can be performed correctly at one time, and therefore no HARQ retransmission is required. Therefore, in the DRX mechanism, the corresponding DRX timer does not need to be started for the HARQ process corresponding to the SPS PDSCH transmission without feedback, thereby simplifying the implementation of the terminal. Of course, as an implementation method, the corresponding DRX timer or a corresponding part of the DRX timer can be started.

[0042] In this embodiment, the target DRX timer is started or not started based on the transmission time of the target PDSCH, thereby ensuring that the terminal and the network have the same understanding of the state and time period for monitoring the downlink control channel, and thereby ensuring the transmission performance of air interface data.

[0043] As can be understood, the predetermined operation may include one or more of (1)-(5) above, and can be specifically determined according to actual communication needs, and the present embodiment is not limited thereto.

[0044] In the embodiment of the present application, for the situation where the target PDSCH is configured without target HARQ-ACK information feedback or there is feedback delay in the target HARQ-ACK information corresponding to the target PDSCH, a predetermined operation can be performed according to the transmission time of the target PDSCH, where the predetermined operation includes at least one of: determining whether the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit, determining the activation time of the target MAC CE, determining the target HARQ-ACK codebook corresponding to the target PDSCH, determining the application of the first rule, and determining the start of the target DRX timer, so that the function dependent on or related to the HARQ-ACK feedback can be normally performed, and communication performance can be ensured.

[0045] As shown in Figure 3, a flowchart of a communication processing method 300 according to an exemplary embodiment of the present application, the method 300 can be applied to a communication device, such as a user terminal, a network device, etc., and may be specifically implemented by hardware and / or software installed in the communication device. The method 300 may include the following steps:

[0046] In S310, a predetermined operation is performed according to the transmission time of the target physical downlink shared channel (PDSCH).

[0047] Here, the implementation process of S310 can refer to the relevant description in S210. In this embodiment, the implementation process of S310 is different based on the differences of the target PDSCH and / or the specified operation, and this embodiment further describes the implementation process of S310 in combination with different examples.

[0048] Example 1 When the specified operation is an operation of determining whether the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit, determining whether the target PDSCH corresponds to a nominal HARQ feedback time unit may include any one of the following (1)-(2).

[0049] (1) The target PDSCH does not correspond to the first nominal HARQ-ACK feedback time unit.

[0050] In one implementation, if the target PDSCH is a no-feedback PDSCH, the target PDSCH does not correspond (ie does not exist) to a first nominal HARQ-ACK feedback time unit (ie, nominal HARQ-ACK feedback time unit).

[0051] (2) The target PDSCH corresponds to a first nominal HARQ-ACK feedback time unit.

[0052] Wherein, when the target PDSCH corresponds to a first named HARQ-ACK feedback time unit, determining the first named HARQ-ACK feedback time unit includes any one of the following (21)-(22):

[0053] (21) Determine the first nominal HARQ-ACK feedback time unit based on the transmission time and a first time indicated by predetermined indication information.

[0054] Wherein, the transmission time is a transmission end time of the target PDSCH, or the transmission time is a time unit in which the transmission end time of the target PDSCH exists, wherein the time unit in which the transmission end time of the target PDSCH exists may be understood as a time unit in an uplink direction, or an uplink time unit, and may specifically be an uplink slot, an uplink sub-slot, or other predefined time length in an uplink direction.

[0055] As can be understood, assuming that the target PDSCH is located within a time unit n' in the downlink direction (i.e., downlink time unit n') and the transmission end time of the target PDSCH is located within a time unit n in the uplink direction (i.e., uplink time unit n), n' and n are not necessarily equal, and although there is a time domain overlap between the downlink time unit n' and the uplink time unit n, they are not necessarily completely overlapped, and the time period corresponding to the target PDSCH transmission is not necessarily completely located within the uplink time unit n, which is related to parameters such as subcarrier spacing that are independently arranged in the uplink direction and the downlink direction, i.e., the length of the time unit in the uplink direction and the downlink direction may be equal or unequal. In this embodiment, in order to facilitate a unified understanding, the uplink time unit n in which the end time of the target PDSCH transmission is located may be the transmission time. In addition, the time unit may include, but is not limited to, any one of a symbol (OFDM), a sub-slot, and a slot.

[0056] The predetermined indication information may include an activation Downlink Control Information (DCI), a reactivation DCI, or higher layer signaling (e.g., Radio Resource Control (RRC) signaling), etc. If the target PDSCH is an SPS PDSCH, the activation DCI / reactivation DCI is used to realize activation or reactivation of a series of SPS PDSCHs including the target PDSCH.

[0057] In one implementation, after an SPS Config is activated or reactivated by a downlink DCI, the relative timing of the HARQ-ACK feedback of the PDSCH transmission scheduled by the activation DCI or reactivation DCI is indicated by the PDSCH-to-HARQ_feedback timing indicator domain (i.e., the timing indication domain between PDSCH and HARQ feedback) or the upper layer parameter dl-DataToUL-ACK (if the timing indication domain between PDSCH and HARQ feedback does not exist in the DCI). For example, assuming that the value of the PDSCH-to-HARQ_feedback timing indicator domain or the upper layer parameter dl-DataToUL-ACK indication in the activation DCI or reactivation DCI is k, and the end time of the PDSCH transmission scheduled by the activation DCI or reactivation DCI is located in uplink slot n, the corresponding HARQ-ACK feedback time unit is n+k. After this PDSCH transmission, before the release, a series of PDSCH transmissions or transmission opportunities that appear periodically, i.e., SPS PDSCHs, can be a kind of target PDSCH. Assuming that the offset amount between the uplink time unit in which the end time of these SPS PDSCHs or target PDSCHs is located and the first time or first time unit of the predetermined indication is still kept as k, i.e., the end time of the target PDSCH is located in uplink time unit n'', the corresponding first nominal HARQ-ACK feedback time unit is n''+k.

[0058] (22) Determine the first nominal HARQ-ACK feedback time unit based on the transmission time length and a predefined time length.

[0059] Here, it may be understood that the first nominal HARQ-ACK feedback time unit determined in (22) is obtained by delaying one predefined time length backward based on the transmission time (i.e., start time). It should be noted that, for the transmission time, the description in (1) above can be referred to, and will not be further described here.

[0060] The predefined time length may include a predetermined number of time length units, and the time unit may include any one of a symbol, a subslot, and a slot. In this embodiment, the predefined time length (or the predetermined number) may be determined based on a time length required for a terminal to decode a target PDSCH.

[0061] For example, the predefined time length may be a time length corresponding to N time domain symbols, or may be simply understood as N time domain symbols, and in some circumstances, the time obtained after applying the predefined time length based on the transmission time length may be further rounded up, i.e., take an uplink time unit whose corresponding start time is not later than the time obtained above, and take the start time of this uplink time unit or this uplink time unit as the first nominal HARQ-ACK feedback time unit corresponding to the target PDSCH. Optionally, when considering that the start time adopts the end time of the target PDSCH transmission, such a method of determining the predefined time length may be adopted.

[0062] Also, for example, the predefined time length may be a time length corresponding to M uplink slots, or may be simply understood as M uplink slots, or M time units. Optionally, when the start time adopts the end time of an uplink time unit in which the transmission end time of a target PDSCH is located, a method for determining such a predefined time length may be adopted.

[0063] It should be noted that the predefined time period may be configured by higher layer signaling or defined based on a protocol, and there is no limitation thereto.

[0064] As can be understood, in the present example 1, by determining the nominal HARQ-ACK feedback time unit corresponding to the target PDSCH based on the transmission time of the target PDSCH, the function realized based on the conventional HARQ-ACK feedback time can be continued to be performed based on the nominal HARQ-ACK feedback time unit, and the communication performance can be effectively ensured.

[0065] Example 2 When the predetermined operation is the operation of determining the activation time of the target MAC CE, the following will introduce the implementation process of S310 based on the difference of the target PDSCH.

[0066] In a first implementation manner, when the target PDSCH is configured without target HARQ-ACK information feedback, the upper layer may consider that the target PDSCH is configured without feedback of target HARQ-ACK information. In this case, the activation time of the target MAC CE may take into account the successful transmission time of the target PDSCH, and the activation time of the MAC CE may be determined based on this successful transmission time. For example, the successful transmission time of the target PDSCH may be delayed by another predetermined time length (for example, 3 ms) to be the activation time of the target MAC CE.

[0067] Based on this, a process of determining the activation time of the target MAC CE by any one of the following (1)-(4) will be described below.

[0068] (1) Determine the activation time of the target MAC CE based on the transmission time.

[0069] Here, for the transmission time, reference can be made to the relevant description in Example 1, and no further description will be given here.

[0070] In addition, considering that the upper layer configures the target PDSCH without HARQ-ACK information feedback, i.e., when the upper layer configures HARQ-ACK disabling, it is assumed or expected that the SPS PDSCH without feedback will be transmitted correctly at one time, and no HARQ retransmission is required. Therefore, the transmission of the target PDSCH may be considered successful at the transmission end time of the target PDSCH (i.e., the transmission time). Therefore, the transmission success time of the target PDSCH may be determined directly based on the transmission time, i.e., the transmission success time of the target PDSCH may be the transmission end time of the target PDSCH or may be the time unit in which the transmission end time of the target PDSCH is located.

[0071] Finally, the activation time of the target MAC CE is determined based on the successful transmission time of the target PDSCH.

[0072] As can be understood, at this time, when determining the activation time of the target MAC CE, there is no need to consider the HARQ-ACK feedback time or feedback time unit corresponding to the target PDSCH, or the activation time of the target MAC CE carried on the target PDSCH is not determined based on the HARQ-ACK feedback time or feedback time unit corresponding to the target PDSCH, but the activation time of the target MAC CE carried on the target PDSCH is determined based on the transmission time of the target PDSCH (e.g., the above-mentioned successful transmission time).

[0073] (2) determining a validation time of the target MAC CE based on the transmission time and a first time indicated by predetermined indication information;

[0074] (3) determining an activation time for the target MAC CE based on the transmission time length and a predefined time length;

[0075] It should be noted that considering that the first nominal HARQ-ACK feedback time unit corresponding to the target PDSCH can be taken as the transmission success time of the target PDSCH, therefore, in (2) and (3) above, the process of determining the transmission success time of the target PDSCH can refer to the determination process for the first nominal HARQ-ACK feedback time unit in Example 1 above, and the determined first nominal HARQ-ACK feedback time unit is taken as the transmission success time of the target PDSCH, and then the activation time of the target MAC CE is determined based on the transmission success time of the target PDSCH, and in order to avoid repetition, no further description will be given here.

[0076] (4) When the target PDSCH corresponds to a second named HARQ-ACK feedback time unit, determine the activation time of the target MAC CE according to the second named HARQ-ACK feedback time unit.

[0077] Here, the second nominal HARQ-ACK feedback time unit may be the same as the first nominal HARQ-ACK feedback time unit in Example 1, or the second nominal HARQ-ACK feedback time unit may be indicated by higher layer signaling or specified by a protocol, etc., and is not limited thereto.

[0078] As can be understood, when the second name HARQ-ACK feedback time unit is the same as the first name HARQ-ACK feedback time unit in Example 1, the determination process of the second name HARQ-ACK feedback time unit may refer to the relevant description regarding the determination of the first name HARQ-ACK feedback time unit in Example 1, and will not be further described here.

[0079] Furthermore, the process of determining the activation time of the target MAC CE based on the second named HARQ-ACK feedback time unit may include delaying the second named HARQ-ACK feedback time unit by a predetermined time length to obtain the activation time of the MAC CE.

[0080] In a second implementation method, when there is a feedback delay in the target HARQ-ACK information corresponding to the target PDSCH, a certain operation is performed based on the transmission time of the target PDSCH, and includes any one of the following (1) to (3):

[0081] (1) Determine a validation time of the target MAC CE based on the transmission time and a first time indicated by predetermined indication information.

[0082] Here, the decision process of determining the activation time of the target MAC CE in (1) may refer to the related description, and will not be further described here to avoid repetition.

[0083] (2) Determine the activation time of the target MAC CE based on the transmission time length and the feedback delay time length.

[0084] Here, the transmission time is a transmission end time of the target PDSCH, or the transmission time is a time unit in which the transmission end time of the target PDSCH exists.

[0085] The feedback delay time length k' can be determined based on the feedback delay time of the target HARQ-ACK information, i.e., k' may be understood to be the time domain offset amount between the uplink time unit n+k' in which the feedback of the delayed target HARQ-ACK information exists and the uplink time unit n in which the transmission end time of the target PDSCH exists (the time unit here may be a slot or a sub-slot, and the time domain offset may be understood to be the difference with the granularity of the time unit).

[0086] As can be understood, in (2), it can be considered that the transmission success time of the target PDSCH is first determined based on the transmission time and the feedback delay time length, and then the activation time of the target MAC CE is determined based on the transmission success time, for example, a predetermined time length is delayed on the transmission success time to obtain the activation time of the target MAC CE.

[0087] (3) When the target PDSCH corresponds to a second named HARQ-ACK feedback time unit, determine an activation time of the target MAC CE according to the second named HARQ-ACK feedback time unit.

[0088] Here, the implementation process of (3) may refer to the relevant description in the first implementation manner, for example, the second nominal HARQ-ACK feedback time unit may be the same as the first nominal HARQ-ACK feedback time unit in Example 1, or the second nominal HARQ-ACK feedback time unit may be indicated by higher layer signaling or specified by a protocol, etc., and in order to avoid repetition of description, no further description will be given here.

[0089] In the present example 2, the activation time of the target MAC CE is determined for the target PDSCH based on the transmission time of the target PDSCH (e.g., the time of successful transmission), thereby ensuring that the flow for determining the activation time of the target MAC CE is executed correctly and that the network side and the terminal have the same understanding of the activation time of the MAC CE, thereby guaranteeing communication performance.

[0090] Example 3 This example 3 introduces an implementation process of S310 when the target PDSCH is configured without feedback of target HARQ-ACK information, and the predetermined operation is an operation of determining the target HARQ-ACK codebook corresponding to the target PDSCH.

[0091] When the target PDSCH does not correspond to the second named HARQ-ACK feedback time unit, the target PDSCH does not have a corresponding target HARQ-ACK codebook, or when the target PDSCH corresponds to the second named HARQ-ACK feedback time unit, the target PDSCH has a corresponding target HARQ-ACK codebook. Here, for the second named HARQ-ACK feedback time unit, reference may be made to the relevant description in Example 2, and in order to avoid repetition, no further description will be given here.

[0092] As can be understood, the second nominal HARQ-ACK feedback time unit may be the same as the first nominal HARQ-ACK feedback time unit in Example 1, or the second nominal HARQ-ACK feedback time unit may be specified by an upper layer signaling configuration or protocol, etc., and will not be further described here to avoid repetition.

[0093] In this embodiment, the target HARQ-ACK codebook may correspond to a first type HARQ-ACK codebook or a second type HARQ-ACK codebook. Here, the first type HARQ-ACK codebook may include any one of a codebook including only a semi-persistent scheduling HARQ-ACK (SPS HARQ-ACK only), a Type-2 codebook, and an enhanced Type-2 codebook. The second type HARQ-ACK codebook may include a Type-1 codebook or a Type-3 codebook.

[0094] In a first implementation manner, when there is a target HARQ-ACK codebook corresponding to the target PDSCH and the target HARQ-ACK codebook corresponds to a first type HARQ-ACK codebook, no HARQ-ACK information is fed back within the second nominal HARQ-ACK feedback time unit, or the first HARQ-ACK information is fed back within the second nominal HARQ-ACK feedback time unit, and the first HARQ-ACK information is HARQ-ACK information other than the target HARQ-ACK information. The target HARQ-ACK information here refers to HARQ-ACK information that needs to be carried or reported in the target HARQ-ACK codebook when the SPS Config corresponding to the SPS PDSCH without feedback is not configured to adopt a HARQ-ACK disabling scheme, and the target HARQ-ACK information may be understood to correspond to the SPS PDSCH without feedback (i.e., the target PDSCH). As can be understood, whether or not to feed back the first HARQ-ACK information within the second nominal HARQ-ACK feedback time unit depends on whether or not the first HARQ-ACK information is included in the target HARQ-ACK codebook.

[0095] Exemplarily, assuming that there is no other HARQ-ACK information (including HARQ-ACK for dynamic scheduling PDSCH, normal SPS PDSCH, and SPS release, etc.) that needs to be fed back within the second nominal HARQ-ACK feedback time unit other than the target HARQ-ACK information corresponding to the target PDSCH, it may be understood that no HARQ-ACK is fed back within this second nominal HARQ-ACK feedback time unit, and no first HARQ-ACK information is fed back; otherwise, only other HARQ-ACKs than the target HARQ-ACK information corresponding to the target PDSCH are fed back within this second nominal HARQ-ACK feedback time unit, which is the first HARQ-ACK information to be fed back.

[0096] In this implementation, the number of HARQ-ACK bits in the first type HARQ-ACK codebook can be determined based on dynamic scheduling or the transmission status of the target PDSCH that is actually transmitted. Here, the transmission status may be understood as needing to feed back the time position and number of PDSCH transmissions or DCI indications of HARQ-ACK within the time unit in which the target HARQ-ACK codebook is located. With regard to feeding back HARQ-ACK within a designated time unit, it may be understood that if the HARQ-ACK feedback time corresponding to a certain PDSCH transmission or a certain DCI indication corresponds to a designated time unit (e.g., uplink slot or uplink sub-slot), the HARQ-ACK corresponding to this PDSCH transmission or this DCI indication is fed back within this designated time unit.

[0097] However, it should be noted that when the target HARQ-ACK codebook corresponds to a codebook including only the semi-persistent scheduling HARQ-ACK, the SPS HARQ-ACK bit sequence corresponding to the target HARQ-ACK codebook does not include a HARQ-ACK bit or HARQ-ACK bit sequence corresponding to the target PDSCH, and in this case, the HARQ-ACK bit or HARQ-ACK bit sequence corresponding to the target PDSCH may be understood as target HARQ-ACK information corresponding to the target PDSCH expressed in HARQ-ACK bit or bit sequence format. For example, for a codebook such as SPS HARQ-ACK only, if the uplink time unit in which its transmission time is located is a second nominal HARQ-ACK feedback time unit, the SPS HARQ-ACK bit sequence can be organized according to a cyclic structure of "Serving cell -> SPS Config -> DL slot", or the SPS HARQ-ACK bit sequence needs to be cyclically determined according to an order specified for multiple dimensions including the dimensions of Serving cell, SPS Config, and DL slot / SPS PDSCH, and the HARQ-ACK bit / bit sequence corresponding to the SPS PDSCH without feedback needs to be skipped in the cyclic process, that is, the finally obtained or transmitted SPS HARQ-ACK bit sequence does not include the HARQ-ACK bit or bit sequence corresponding to the SPS PDSCH without feedback.

[0098] In some circumstances, for a Type-2 codebook or an enhanced Type-2 codebook, if an SPS HARQ-ACK exists, the corresponding bit sequence is appended after the dynamic scheduling HARQ-ACK bit sequence, and the organization of the SPS HARQ-ACK bit sequence can be reused from the processing when there is only an SPS HARQ-ACK. See the corresponding description above.

[0099] In a second implementation manner, when a target HARQ-ACK codebook corresponding to the target PDSCH exists and the target HARQ-ACK codebook corresponds to a second type HARQ-ACK codebook, the number of HARQ-ACK bits in the second type HARQ-ACK codebook is determined based on upper layer semi-static parameters, and is not dependent on dynamic scheduling or the transmission situation of the actually transmitted PDSCH.

[0100] In this embodiment, in order to be compatible with various dynamic scheduling or transmission situations of PDSCH actually transmitted, the second type HARQ-ACK codebook reserves corresponding HARQ-ACK bits for PDSCH transmission (including SPS PDSCH) in all possible situations. Therefore, for SPS PDSCH without feedback, there may be HARQ-ACK bits corresponding to such codebook. Due to the limitation of the semi-static HARQ-ACK bit number attribute, these HARQ-ACK bits cannot be reduced, otherwise it may cause inconsistency in understanding of the bit number or bit mapping relationship on both sides, such as when multiplexing with dynamic scheduling HARQ-ACK and there is DCI missed detection.

[0101] As can be understood, if there is a target HARQ-ACK codebook corresponding to the target PDSCH, and the target HARQ-ACK codebook corresponds to a second type HARQ-ACK codebook, then there necessarily exists a HARQ-ACK bit corresponding to the target PDSCH in the target HARQ-ACK codebook.

[0102] In this case, the present embodiment sets a first HARQ-ACK bit in the target HARQ-ACK codebook according to any one of the following (1)-(4), where the first HARQ-ACK bit corresponds to the target PDSCH.

[0103] (1) Setting the first HARQ-ACK bit to a first predetermined value.

[0104] Here, the first predetermined value may be ACK, i.e., it is assumed that the target PDSCH can always be transmitted correctly at one time, so the first HARQ-ACK bit is always set to ACK. Alternatively, the first HARQ-ACK bit may be set to NACK.

[0105] (2) Setting the first HARQ-ACK bit based on a decoding result of the target PDSCH.

[0106] Here, the value setting of the first HARQ-ACK bit is the same as that when the HARQ-ACK disabling scheme is not configured. For example, if the decoding result is a decoding failure, the value of the first HARQ-ACK bit may be set to NACK, and if the decoding result is a decoding success, the value of the first HARQ-ACK bit may be set to ACK.

[0107] (3) Setting the first HARQ-ACK bit according to the case where the target PDSCH transmission is not occurring.

[0108] Here, the setting manner of the first HARQ-ACK bit is different according to the difference of the second type HARQ-ACK codebook. For example, when the target HARQ-ACK codebook corresponds to a Type-1 codebook, the first HARQ-ACK bit is set to a second predetermined value. That is, for a Type-1 codebook, it may be considered to set the first HARQ-ACK bit to a default value (i.e., a second predetermined value). Here, the second predetermined value may be, but is not limited to, NACK.

[0109] Also, for example, when the target HARQ-ACK codebook corresponds to a Type-3 codebook, the first HARQ-ACK bit is set according to a first PDSCH, the first PDSCH and the target PDSCH correspond to the same HARQ process, and the transmission time of the first PDSCH is earlier than the transmission time of the target PDSCH. That is, assuming that the target PDSCH is an SPS PDSCH, for a Type-3 codebook, if the nearest PDSCH transmission of a certain HARQ process is an SPS PDSCH without feedback, the bit setting corresponding to this HARQ process is set according to the dynamic scheduling PDSCH transmission situation for this HARQ process before this SPS PDSCH without feedback or the normal SPS PDSCH transmission situation.

[0110] (4) The transmitting side does not place any restrictions on how to set the first HARQ-ACK bit, and the receiving side ignores the value of the first HARQ-ACK bit.

[0111] At this time, how the transmitting side (e.g., a terminal) sets the first HARQ-ACK bit may be based on implementation or set to an arbitrary value, and these HARQ-ACK bits are directly ignored by the receiving side (e.g., a network device) and do not cause any additional impact.

[0112] It should be noted that for a Type-1 codebook, only the value that HARQ-ACK feedback refers to the HARQ-ACK bit (in the codebook) corresponding to the PDSCH of the uplink time unit where the codebook transmission is located is valid, so for a SPS PDSCH without feedback, only if there is a corresponding nominal HARQ-ACK feedback time unit, and the uplink time unit where Type-1 codebook transmission is located, there is a HARQ-ACK bit corresponding to this SPS PDSCH without feedback in the Type-1 codebook. It should be noted that for a certain uplink time unit (such as a certain uplink slot or subslot), in addition to the HARQ-ACK corresponding to the SPS PDSCH without feedback, if there is no HARQ-ACK feedback for PDSCH dynamic scheduling or SPS release, no feedback of the normal Type-1 codebook is provided, and at this time, the corresponding process for SPS HARQ-ACK only in the first type HARQ-ACK codebook can be referred to. For a feedback-free SPS PDSCH, if there is no corresponding nominal HARQ-ACK feedback time unit, it does not correspond to a Type-1 codebook in any uplink time unit.

[0113] For the Type-3 codebook, it is organized based on the HARQ process, so there is no need to pay attention to whether there is a nominal HARQ-ACK feedback time unit corresponding to the SPS PDSCH without feedback. If the recent PDSCH transmission of a certain HARQ process is an SPS PDSCH without feedback, it can be considered that there is a HARQ-ACK bit corresponding to the SPS PDSCH without feedback in the Type-3 codebook of the HARQ-ACK including this HARQ process.

[0114] As can be understood, when the HARQ-ACK bit is set to ACK, the bit value may be set to 1, and when the HARQ-ACK bit is set to NACK, the bit value may be set to 0.

[0115] In some situations, for a second type HARQ-ACK codebook, if there are first HARQ-ACK bits in it, these first HARQ-ACK bits may be removed from the codebook when the codebook is actually transmitted, and only the (new) codebook configured with the other HARQ-ACK bits in the codebook may be transmitted. However, such a method may cause a misunderstanding of the number of bits in the transmitted codebook on both sides if DCI detection is missed on the terminal side, thereby affecting HARQ-ACK feedback performance.

[0116] Based on the above two implementation methods, according to the provisions of related protocols, the number of uplink control information (UCI) bits carried on the PUCCH is set to 11 (i.e.

number

[0117] In the following, the calculation of the PUCCH power control variable for different codebook types is described.

[0118] (1) For the first type of HARQ-ACK codebook (including Type-2 codebook), when it is actually transmitted, the codebook does not include the HARQ-ACK bit corresponding to the SPS PDSCH without feedback, and at this time, the calculation of the PUCCH power control variable nHARQ-ACK also excludes the HARQ-ACK bit corresponding to the SPS PDSCH without feedback, or excludes the SPS PDSCH without feedback, that is, the SPS PDSCH without feedback is not included in the PDSCH or TB count.

[0119] (2) For the second type of HARQ-ACK codebook, since the Type-3 codebook currently does not consider the situation where the number of UCI bits does not exceed 11, this embodiment only describes the calculation of the PUCCH power control variable corresponding to the Type-1 codebook here.

[0120] Here, when the target HARQ-ACK codebook corresponds to a Type-1 codebook, the PUCCH power control variable corresponding to the target HARQ-ACK codebook (corresponding to a Type-1 codebook) can be calculated by the following (21) or (22).

[0121] (21) When calculating the PUCCH power control variable, the target PDSCH is included in the received PDSCH count. In this calculation method, the PUCCH power control variable n HARQ-ACK The calculation of takes into account the first HARQ-ACK bit corresponding to the SPS PDSCH without feedback, or takes into account the SPS PDSCH without feedback or the TB (Transport Block) or CBG (Code Block Group) carried on it, and the calculation method can be based on the conventional protocol specifications.

[0122] In addition, the setting method of the first HARQ-ACK bit may include setting the first HARQ-ACK bit to a first predetermined value, or setting the first HARQ-ACK bit based on the decoding result of the target PDSCH. For details, please refer to the related description above. In order to avoid repetition, no further description will be given here.

[0123] (22) When calculating the PUCCH power control variable, the target PDSCH is not considered (or the feedback-free SPS PDSCH is excluded, i.e., the feedback-free SPS PDSCH is not included in the PDSCH or TB count). In this calculation method, the PUCCH power control variable n HARQ-ACK may be thought of as not taking into account the first HARQ-ACK bit corresponding to the SPS PDSCH without feedback, or not taking into account the SPS PDSCH without feedback or the TB (Transport Block) or CBG (Code Block Group) carried on it, i.e. excluding it when calculating the PUCCH power control variable.

[0124] In addition, the above-mentioned first HARQ-ACK bit setting method may be a method of setting the first HARQ-ACK bit according to a situation where the target PDSCH transmission does not occur. For details, please refer to the related description above. In order to avoid repetition, no further description will be given here.

[0125] In the third example, for a target PDSCH, a target HARQ-ACK codebook corresponding to the target PDSCH and a PUCCH power control variable are determined based on the transmission time of the target PDSCH, thereby ensuring communication performance.

[0126] Example 4 Example 4 describes the implementation process of S310 when the predetermined operation is the operation that determines the application of the first rule.

[0127] In a first implementation manner, when the target PDSCH is configured without target HARQ-ACK information feedback, determining the application of the first rule includes any one of the following (1) and (2):

[0128] (1) The first rule does not apply to the target PDSCH.

[0129] Here, for the target PDSCH, including the SPS PDSCH without feedback, the first rule may be unified and not applied, based on the configuration, because there is no actual HARQ-ACK feedback. In some circumstances, when the target PDSCH does not correspond to the nominal HARQ-ACK feedback time unit, the target PDSCH does not apply the first rule, that is, the first rule cannot be applied because there is no HARQ-ACK feedback time corresponding to the target PDSCH, and when the target PDSCH corresponds to the nominal HARQ-ACK feedback time unit, the target PDSCH may apply the first rule.

[0130] (2) The first rule is applied to the target PDSCH.

[0131] Here, it can be unified that the target PDSCH includes the SPS PDSCH without feedback, and still applies the first rule. At this time, when applying the first rule, it is necessary to use the HARQ-ACK feedback time corresponding to the target PDSCH. At this time, when the target PDSCH corresponds to the nominal HARQ-ACK feedback time unit, the first rule can be applied by using the corresponding nominal HARQ-ACK feedback time unit as the corresponding HARQ-ACK feedback time; when the target PDSCH does not correspond to the nominal HARQ-ACK feedback time unit, the corresponding HARQ-ACK feedback time unit can be determined by using another method, and the first rule can be applied.

[0132] In some circumstances, when the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit, the target PDSCH may apply the first rule. In this case, the above-mentioned first rule may be applied based on the nominal HARQ-ACK feedback time unit corresponding to the target PDSCH without feedback. As can be understood, when the target PDSCH applies the first rule, the first feedback time corresponding to the target HARQ-ACK information may be a second nominal HARQ-ACK feedback time unit corresponding to the target PDSCH.

[0133] Here, the second name HARQ-ACK feedback time unit may be the same as the first name HARQ-ACK feedback time unit in the example 1, or the second name HARQ-ACK feedback time unit may be defined by a higher layer signaling configuration or protocol, etc., and is not limited herein. It can be understood that, when the second name HARQ-ACK feedback time unit is the same as the first name HARQ-ACK feedback time unit in the example 1, the determination process of the second name HARQ-ACK feedback time unit may refer to the related description about the first name HARQ-ACK feedback time unit in the example 1, and will not be further described here.

[0134] In a second implementation manner, when there is a feedback delay in the target HARQ-ACK information corresponding to the target PDSCH, determining the application of the first rule includes any one of the following (1) or (2):

[0135] (1) The first rule does not apply to the target PDSCH.

[0136] As can be seen, for the target PDSCH, the predefined HARQ-ACK feedback position cannot be actually fed back, and therefore the target PDSCH does not apply the first rule. The delayed HARQ-ACK feedback position may be regarded as a HARQ-ACK retransmission, and the conclusion of relaxing based on the OoO request for HARQ-ACK retransmission in NR-U (i.e., the OoO request applies only to the assigned initial HARQ-ACK transmission occasion) does not require the OoO rule (i.e., the first rule) to be applied.

[0137] (2) The first rule is applied to the target PDSCH.

[0138] As can be understood, the target PDSCH applies the OoO rule between PDSCH reception and HARQ-ACK feedback, and the second feedback time for applying the OoO rule at this time can be determined by any one of the following methods (1) to (3), and the second feedback time is the feedback time of the target HARQ-ACK information corresponding to the target PDSCH.

[0139] (1) Determine the second feedback time based on the transmission time and a first time indicated by specified instruction information, where the transmission time is the transmission end time of the target PDSCH, or the transmission time is a time unit in which the transmission end time of the target PDSCH is located.

[0140] (2) determining the second feedback time based on the transmission time and a feedback delay time length, and the feedback delay time length is determined based on the feedback delay time of the target HARQ-ACK information;

[0141] (3) When the target PDSCH corresponds to a second named HARQ-ACK feedback time unit, determine the second feedback time according to the second named HARQ-ACK feedback time unit.

[0142] Example 5 Example 5 describes the implementation process of S310 on the basis that the predetermined operation is to turn on the determined target DRX timer.

[0143] Here, when the target PDSCH is configured without target HARQ-ACK information feedback and configured to turn on the DRX mechanism, the target DRX timer includes a downlink HARQ round trip time timer (drx-HARQ-RTT-TimerDL) and a downlink retransmission timer (drx-Retransmission-TimerDL).

[0144] In this example, the above-mentioned determining to start the target DRX timer may include any of the following (1)-(4).

[0145] (1) After receiving the target PDSCH, the drx-HARQ-RTT-TimerDL and the drx-RetransmissionTimerDL are not started.

[0146] (2) After receiving the target PDSCH, start the drx-HARQ-RTT-TimerDL, and if the drx-HARQ-RTT-TimerDL times out, do not start the drx-RetransmissionTimerDL.

[0147] (3) After receiving the target PDSCH, start the drx-HARQ-RTT-TimerDL, and if the drx-HARQ-RTT-TimerDL times out and the first HARQ process does not succeed in decoding, start the drx-RetransmissionTimerDL.

[0148] (4) After receiving the target PDSCH, the drx-HARQ-RTT-TimerDL is not started, but the drx-RetransmissionTimerDL is started.

[0149] In the four implementation methods, starting the drx-HARQ-RTT-TimerDL may include starting the drx-HARQ-RTT-TimerDL at a third feedback time, where the third feedback time is determined by any one of the following (a)-(d):

[0150] (a) determining the third feedback time based on the transmission time, where the transmission time is a transmission end time of the target PDSCH, or the transmission time is a time unit in which the transmission end time of the target PDSCH resides;

[0151] (b) determining the third feedback time based on the transmission time and a first time indicated by predetermined indication information;

[0152] (c) determining the third feedback time based on the transmission time length and a predefined time length;

[0153] (d) when the target PDSCH corresponds to a second named HARQ-ACK feedback time unit, determining the third feedback time according to the second named HARQ-ACK feedback time unit.

[0154] The process of determining the third feedback time based on (a)-(d) may refer to the relevant descriptions in each of the above examples, and will not be described further here to avoid repetition.

[0155] Based on each of the above examples, and based on the differences in the specified operations, the realization process of the communication processing method provided by this embodiment may include one or more of Examples 1 to 5. For example, when the specified operation includes determining whether the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit, and determining the activation time of the target MAC CE, the realization process of the communication processing method may include the realization methods in Examples 1 and 2, and this embodiment is not limited thereto.

[0156] It should be noted that the communication processing method 300 provided in this embodiment ensures communication performance by introducing a series of adaptive solutions for different target PDSCHs and / or predetermined operations.

[0157] For example, when a HARQ-ACK disabling method is adopted for a certain SPS Config configuration, a set of adaptive methods is introduced for functions and processes that depend on or are related to HARQ-ACK feedback, thereby ensuring that the HARQ-ACK disabling method can be fully applied and achieving the goal of reducing the SPS HARQ-ACK feedback load.

[0158] For example, when SPS HARQ-ACK is fed back with a delay in a TDD system, a series of adaptability schemes are introduced for functions and processes that depend on or are related to HARQ-ACK feedback to ensure consistency of understanding between the UE and the network.

[0159] It should be noted that in each of the above embodiments, each communication device (including terminal side device and network side device) involved in the communication processing process has a consistent understanding of the communication processing method. For example, when the terminal side device performs a certain operation based on the transmission time of the target PDSCH, a corresponding protocol or configuration is pre-configured for the network side device corresponding to the terminal side device, so that the network side device can understand the operation performed by the terminal side device, thereby ensuring the smooth execution of the communication process.

[0160] In addition, the execution body of the communication processing method according to the embodiment of the present application may be a communication processing device, or may be a control module for executing the communication processing method in the communication processing device. In the embodiment of the present application, the communication processing device according to the embodiment of the present application will be described by taking as an example a case in which the communication processing device executes the communication processing method.

[0161] As shown in FIG. 4, it is a block diagram of a communication processing device 400 according to an exemplary embodiment of the present application, the device includes: an execution module 410 for performing a predetermined operation according to a transmission time of a target physical downlink shared channel (PDSCH), where the target PDSCH is configured without a target hybrid automatic repeat request response (HARQ-ACK) information feedback, or there is a feedback delay in the target HARQ-ACK information corresponding to the target PDSCH, the predetermined operation is to determine whether the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit, and to determine an activation time of a target MAC CE, and the target MAC The CE includes at least one of: being carried on the target PDSCH; determining a target HARQ-ACK codebook corresponding to the target PDSCH; determining application of a first rule, the first rule expressing a timing relationship requirement between the target PDSCH and a feedback time corresponding to the target HARQ-ACK information; and determining to start a target Discontinuous Reception DRX timer, the target DRX timer corresponding to a first HARQ process, and the first HARQ process corresponding to the target PDSCH.

[0162] In one possible implementation manner, when the predetermined operation is an operation of determining whether the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit, the execution module 410 determining the nominal HARQ feedback time unit corresponding to the target PDSCH includes either: the target PDSCH does not correspond to a first nominal HARQ-ACK feedback time unit; or the target PDSCH corresponds to a first nominal HARQ-ACK feedback time unit.
