[0017] Hereinafter, with reference to the drawings, the technical solution according to the embodiments of the present application will be described in detail by specific embodiments and their application scenarios.

[0018] As shown in FIG. 2, it is a flowchart of a communication processing method 200 according to an exemplary embodiment of the present application. This method 200 can be applied to a communication device (such as a terminal, a network device, etc.), and specifically may be executed by the 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 executed based on the transmission time of the target PDSCH.

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

[0022] Alternatively, there is a feedback delay in the target HARQ-ACK information corresponding to the target PDSCH. For example, the SPS HARQ-ACK corresponding to the target PDSCH in a Time Division Duplex (TDD) system cannot perform feedback at a predefined feedback position due to a transmission resource direction collision at the predefined feedback position, and it is necessary to delay the feedback.

[0023] In this embodiment, the target PDSCH may be, for example, an SPS PDSCH. Accordingly, the target HARQ-ACK information may be SPS HARQ-ACK information corresponding to the SPS PDSCH. In some situations, the target PDSCH may be a dynamically scheduled PDSCH, or the target PDSCH may be further extended 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 the PUSCH and be transmitted by the network device to the terminal. For example, the target HARQ-ACK information may also correspond to the Configured Grant downlink feedback information (CG-DFI) in NR-U. In this embodiment, there is no limitation here.

[0024] It should be noted that for the convenience of description, in the subsequent embodiments, when a HARQ-ACK disabling scheme is arranged for a certain SPS configuration (SPS Config) of the target PDSCH, the corresponding SPS PDSCH may be hereinafter referred to as the feedback-free SPS PDSCH, and the SPS PDSCH corresponding to other SPS Configurations (where HARQ-ACK disabling is not arranged) may be hereinafter referred to as the normal SPS PDSCH. The SPS PDSCH described hereinafter generally refers to the SPS PDSCH transmission corresponding to the SPS Config, including the feedback-free SPS PDSCH and the 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, the nominal HARQ-ACK feedback time unit may be the HARQ-ACK feedback time of the SPS PDSCH, or when it is necessary to use the HARQ-ACK feedback time unit, this nominal HARQ-ACK feedback time unit, or the 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). It may be understood that it is also possible to use it, and it can be guaranteed that the subsequent functions or processes of the HARQ-ACK feedback time or HARQ-ACK feedback time unit depending on the SPS PDSCH are executed smoothly.

[0028] For a feedbackless SPS PDSCH (i.e., the SPS PDSCH corresponding to the SPS Config arranged without HARQ-ACK information feedback) that is arranged at the upper layer so as not to require HARQ-ACK feedback, although there may still be a corresponding HARQ-ACK feedback time, i.e., the nominal HARQ-ACK feedback time, or nominal HARQ-ACK feedback time unit, for each feedbackless SPS PDSCH, of course, there may be no corresponding nominal HARQ-ACK feedback time unit for each feedbackless SPS PDSCH.

[0029] Optionally, if there is a nominal HARQ-ACK feedback time unit corresponding to a certain feedbackless SPS PDSCH, at this nominal HARQ-ACK feedback time unit or nominal HARQ-ACK feedback time (for example, determining this nominal HARQ-ACK feedback time based on the end time of the nominal HARQ-ACK feedback time unit), this feedbackless SPS PDSCH, i.e., the target PDSCH, may be regarded as having confirmed the success of the transmission, so the nominal HARQ-ACK feedback time unit or nominal HARQ-ACK feedback time may be used as the transmission success time of the target PDSCH.

[0030] For an SPS PDSCH with a feedback delay in the corresponding HARQ-ACK information (for example, in a TDD system, since the resources at the predefined feedback time position cannot be used, there is a feedback delay in the HARQ-ACK information of this SPS PDSCH), the concept of a nominal HARQ-ACK feedback time unit or nominal HARQ-ACK feedback time can also be introduced. At this time, the nominal HARQ-ACK feedback time unit or nominal HARQ-ACK feedback time may be determined based on the predefined / pre-instructed feedback time unit / feedback time, or may be determined based on other methods.

[0031] (2) Determine the activation time of the target Medium Access Control-Control Element (MAC CE).

[0032] Here, the target MAC CE is carried on the target Physical Downlink Shared Channel (PDSCH). In NR, an indication method based on MAC CE is introduced for multiple functions, which corresponds to L2 signalling. In this embodiment, by determining the activation time of the target MAC CE based on the transmission time of the target PDSCH, when determining the activation time of the target MAC CE based on the Hybrid Automatic Repeat reQuest - Acknowledgement (HARQ-ACK) feedback time, the problem that the HARQ-ACK feedback time cannot be used or is ambiguous can be avoided or solved, and it is ensured to indicate the normal execution of this function or process based on the MAC CE (that is, clearly define the activation time of the MAC CE and ensure that the understanding on the network side and the terminal side is consistent). Understandably, the target MAC CE carried on the target PDSCH is a downlink MAC CE. When this embodiment is extended to the Physical Uplink Shared Channel (PUSCH), correspondingly, the target MAC CE may be an uplink MAC CE.

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

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

[0035] For the different HARQ-ACK codebook types mentioned above, for the SPS PDSCH transmission without feedback (which can be regarded as a situation of a certain type of target PDSCH), and for the correspondence between a certain specific codebook corresponding to a certain HARQ-ACK codebook type (which may be understood as the target HARQ-ACK codebook), and the setting of HARQ-ACK bits in this specific codebook, corresponding rules are required to ensure the consistency of understanding on both sides. In this embodiment, based on the transmission time of the target PDSCH, the target HARQ-ACK codebook can be determined, thereby ensuring the correspondence between the PDSCH and the HARQ-ACK codebook, and the consistency of understanding on both sides regarding the setting of HARQ-ACK bits in the HARQ-ACK codebook.

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

[0037] Here, the first rule represents the 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 earlier must not be later than the HARQ-ACK feedback of the PDSCH that starts transmission later, thereby ensuring that the terminal side can execute operations such as receiving scheduling downlink control information (DCI), receiving the PDSCH, and providing HARQ-ACK feedback in a pipelined manner, avoiding disorder in the order, and reducing the implementation complexity of the terminal. It should be understood that the first rule above may be understood as an Out-of-Order rule, or an OoO rule, or a rule to ensure order, or a rule to avoid disorder in order.

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

[0039] (5) Determine the activation of the target discontinuous reception (DRX) timer.

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

[0041] In the case of SPS PDSCH without feedback, when the upper layer configures the HARQ-ACK disabling scheme, considering that it has already been assumed or expected that correct transmission can be achieved at one time, HARQ retransmission is not required. Therefore, in the DRX mechanism, for the HARQ process corresponding to SPS PDSCH transmission without feedback, it may not be necessary to activate the corresponding DRX timer, thereby simplifying the implementation of the terminal. Of course, as one implementation method, the corresponding DRX timer or some of the corresponding DRX timers may also be activated.

[0042] In this embodiment, based on the transmission time of the target PDSCH, by determining the activation or non-activation of the target DRX timer, it is possible to ensure that the terminal and the network side have a consistent understanding of the state and time period for monitoring the downlink control channel, thereby guaranteeing the transmission performance of air interface data.

[0043] As can be understood, the predetermined operation may include one or more of the above (1)-(5), and can be specifically determined according to actual communication requirements, and this embodiment does not limit this.

[0044] In an embodiment of the present application, for a situation where a target PDSCH is arranged without target HARQ-ACK information feedback, or where there is a feedback delay in the target HARQ-ACK information corresponding to the target PDSCH, a predetermined operation can be executed based on the transmission time of the target PDSCH. Here, 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 a target MAC CE, determining the target HARQ-ACK codebook corresponding to the target PDSCH, determining the application of a first rule, and determining the activation of a target DRX timer. Thereby, functions that depend on HARQ-ACK feedback or functions related to HARQ-ACK feedback can be executed normally, ensuring communication performance.

[0045] As shown in FIG. 3, it is a flowchart of a communication processing method 300 according to an exemplary embodiment of the present application. This method 300 can be applied to a communication device, such as a user terminal, a network device, etc., and specifically may be executed 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 executed based on the transmission time of a target physical downlink shared channel PDSCH.

[0047] Here, except that the realization process of S310 can refer to the related description in S210, in this embodiment, based on the differences between the target PDSCH and / or the predetermined operation, the realization process of S310 is different. This embodiment combines different examples to further explain the realization process of S310.

[0048] Example 1 When the predetermined operation is an operation of determining whether or not the target PDSCH corresponds to the nominal HARQ-ACK feedback time unit, determining whether or not the target PDSCH corresponds to the 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 manner, when the target PDSCH is a PDSCH without feedback, the target PDSCH does not correspond to (i.e., does not exist in) the first nominal HARQ-ACK feedback time unit (i.e., the nominal HARQ-ACK feedback time unit).

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

[0052] Here, when the target PDSCH corresponds to the first nominal HARQ-ACK feedback time unit, the determination of the first nominal 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 the first time indicated by the predetermined indication information.

[0054] Here, the transmission time is the transmission end time of the target PDSCH, or the transmission time is the time unit in which the transmission end time of the target PDSCH is located. Here, the time unit in which the transmission end time of the target PDSCH is located may be understood as the time unit in the uplink direction or the uplink time unit, and specifically may be an uplink slot, an uplink sub-slot, or another predefined time length in the uplink direction.

[0055] For ease of understanding, assume that the target PDSCH is located within the downlink time unit n' (i.e., the downlink time unit n'), and the transmission end time of the target PDSCH is located within the uplink time unit n (i.e., the uplink time unit n). In this case, n' and n are not necessarily equal, and there may be an overlap in the time domain between the downlink time unit n' and the uplink time unit n, but they do not necessarily completely overlap. Also, the time period corresponding to the target PDSCH transmission does not necessarily completely fall within the uplink time unit n. This is related to parameters such as the subcarrier spacing that are independently arranged in the uplink and downlink directions, that is, the lengths of the time units in the uplink and downlink directions may or may not be equal. In this embodiment, for the sake of unified understanding, the uplink time unit n where the transmission end time of the target PDSCH is located can be used as the transmission time. Further, 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 activated downlink control information (Downlink Control Information, DCI), reactivated DCI, or upper layer signaling (for example, may include radio resource control (Radio Resource Control, RRC) signaling, etc.). When the target PDSCH is an SPS PDSCH, the activated DCI / reactivated DCI is used to activate or reactivate a series of SPS PDSCHs including the target PDSCH.

[0057] In one implementation, taking a certain SPS Config as an example, after it is activated or reactivated by a downlink DCI, the relative timing of the HARQ-ACK feedback of the PDSCH transmission scheduled by this activation DCI or reactivation DCI is determined by the PDSCH-to-HARQ_feedback timing indicator domain in this activation DCI or reactivation DCI (i.e., the timing indication domain between the PDSCH and the HARQ feedback) or the upper layer parameter dl-DataToUL-ACK (when there is no such timing indication domain between the PDSCH and the HARQ feedback in this 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 this activation DCI or reactivation DCI is k, and the end time of the PDSCH transmission scheduled by this activation DCI or reactivation DCI is located in the uplink slot n, the corresponding HARQ-ACK feedback time unit is n + k. After this PDSCH transmission and before release, a series of periodically appearing PDSCH transmissions or transmission opportunities, i.e., SPS PDSCH, can be regarded as a type of target PDSCH. The offset amount between the uplink time unit where the end time of these SPS PDSCH or target PDSCH is located and the first time of the predetermined indication, or the first time unit, still remains k. That is, assuming that the end time of the target PDSCH is located in the 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 the 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., the start time). It should be noted that for the transmission time, reference may be made to the description in (1) and will not be further elaborated 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) can be determined based on the time length required for the terminal to decode the target PDSCH.

[0061] For example, the predefined time length may be the time length corresponding to N time domain symbols, or may be simply understood as N time domain symbols. In some situations, the time obtained after applying this predefined time length based on the transmission time length may be further rounded up, that is, an uplink time unit whose corresponding start time is not later than the time obtained above is taken, and the start time of this uplink time unit, or this uplink time unit, may be used 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 determination method of the predefined time length may also be adopted.

[0062] Also for example, the predefined time length may be the 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 the uplink time unit where the transmission end time of the target PDSCH is located, such a determination method of the predefined time length may also be adopted.

[0063] It should be noted that the predefined time duration may be arranged by upper layer signaling or defined based on a protocol, and is not limited thereto.

[0064] As can be understood, in this Example 1, based on the transmission time of the target PDSCH, by determining the nominal HARQ-ACK feedback time unit corresponding to the target PDSCH, the functions realized depending on the conventional HARQ-ACK feedback time can continue to be executed depending on the nominal HARQ-ACK feedback time unit, effectively ensuring communication performance.

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

[0066] In the first implementation method, when the target PDSCH is arranged without target HARQ-ACK information feedback, the upper layer may consider that there is no feedback of target HARQ-ACK information to the target PDSCH. In this case, the activation time of the target MAC CE can consider the transmission success time of the target PDSCH, and further determine the activation time of the MAC CE based on this transmission success time. For example, it can be delayed by another predetermined time duration (e.g., 3 ms) from the transmission success time of the target PDSCH to be the activation time of the target MAC CE.

[0067] Based on this, the 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, regarding the transmission time, reference can be made to the relevant description in Example 1, and no further explanation will be provided here.

[0070] Also, the upper layer considers that there is no HARQ-ACK information feedback for the target PDSCH, that is, it is assumed or expected that when HARQ-ACK disabling is configured in the upper layer, the feedback-free SPS PDSCH is correctly transmitted at once without the need for HARQ retransmission. At the transmission end time of the target PDSCH (i.e., the above-mentioned transmission time), it may be considered that the transmission of the target PDSCH is successful. Therefore, the transmission success time of the target PDSCH may be directly determined based on the above-mentioned transmission time, that is, 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 transmission success time of the target PDSCH.

[0072] As can be understood, at this time, when determining the activation time of the target MAC CE, it is not necessary to consider the HARQ-ACK feedback time or feedback time unit corresponding to the target PDSCH, nor to determine the activation time of the target MAC CE carried on this target PDSCH based on the HARQ-ACK feedback time or feedback time unit corresponding to the target PDSCH. Instead, the activation time of the target MAC CE carried on this target PDSCH is determined based on the transmission time of the target PDSCH (for example, the above-mentioned transmission success time).

[0073] (2) Determine the activation time of the target MAC CE based on the transmission time and the first time indicated by the predetermined indication information.

[0074] (3) Determine the activation time of the target MAC CE based on the transmission time duration and a predefined time duration.

[0075] It should be noted that considering that the first nominal HARQ-ACK feedback time unit corresponding to the target PDSCH can be 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 regarding the first nominal HARQ-ACK feedback time unit in Example 1, and set the determined first nominal HARQ-ACK feedback time unit as the transmission success time of the target PDSCH. Next, determine the activation time of the target MAC CE based on the transmission success time of the target PDSCH. To avoid repetition of the description, it will not be further elaborated here.

[0076] (4) When the target PDSCH corresponds to a second nominal HARQ-ACK feedback time unit, determine the activation time of the target MAC CE based on the second nominal 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 upper layer signaling or defined by a protocol, etc., without limitation here.

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

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

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

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

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

[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 the transmission end time of the target PDSCH, or the transmission time is the time unit where the transmission end time of the target PDSCH is located.

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

[0086] As can be understood, in the above (2), first, the transmission success time of the target PDSCH can be determined based on the transmission time and the feedback delay time length, and then, based on the transmission success time, the activation time of the target MAC CE can be determined. For example, the activation time of the target MAC CE can be obtained by delaying a predetermined time length above the transmission success time.

[0087] (3) When the target PDSCH corresponds to the second nominal HARQ-ACK feedback time unit, based on the second nominal HARQ-ACK feedback time unit, determine the activation time of the target MAC CE.

[0088] Here, for the implementation process of the above (3), the related descriptions in the first implementation method can be referred to. 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 upper layer signaling or defined by a protocol, etc. To avoid repetition of the description, it will not be further described here.

[0089] In Example 2, for the target PDSCH, by determining the activation time of the target MAC CE according to the transmission time of the target PDSCH (for example, the transmission success time), the normal execution of the determination flow of the activation time of the target MAC CE is ensured, the consistency of the understanding of the activation time of the MAC CE between the network side and the terminal can be ensured, and thereby the communication performance is guaranteed.

[0090] Example 3 In Example 3, when the target PDSCH is arranged without feedback of target HARQ-ACK information, and the predetermined operation is the operation of determining the target HARQ-ACK codebook corresponding to the target PDSCH, the realization process of S310 is introduced.

[0091] When the target PDSCH does not correspond to the second nominal HARQ-ACK feedback time unit, there is no corresponding target HARQ-ACK codebook for the target PDSCH, or when the target PDSCH corresponds to the second nominal HARQ-ACK feedback time unit, there is a corresponding target HARQ-ACK codebook for the target PDSCH. Here, for the second nominal HARQ-ACK feedback time unit, the relevant description in Example 2 can be referred to, and in order to avoid repetition of the description, it will not be described further 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 defined by upper layer signaling configuration or protocol, etc. In order to avoid repetition of the description, it will not be described further here.

[0093] In this embodiment, the target HARQ-ACK codebook may correspond to a first type of HARQ-ACK codebook or a second type of HARQ-ACK codebook. Here, the first type of HARQ-ACK codebook may include any one of a codebook including only semi-persistent scheduling HARQ-ACK (SPS HARQ-ACK only), a Type-2 codebook, and an enhanced Type-2 codebook. The second type of 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 of HARQ-ACK codebook, no HARQ-ACK information is fed back within the second nominal HARQ-ACK feedback time unit, or first HARQ-ACK information is fed back within the second nominal HARQ-ACK feedback time unit, and the first HARQ-ACK information is other HARQ-ACK information other than the target HARQ-ACK information. Here, the target HARQ-ACK information is 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 does not 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 to feed back the first HARQ-ACK information within the second nominal HARQ-ACK feedback time unit, etc., depends on whether the target HARQ-ACK codebook includes the first HARQ-ACK information, etc.

[0095] Exemplarily, assuming that there is no other HARQ-ACK information (including HARQ-ACK for dynamically scheduled 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 the first HARQ-ACK information is not fed back. Otherwise, only other HARQ-ACK other than the target HARQ-ACK information corresponding to the target PDSCH is fed back within this second nominal HARQ-ACK feedback time unit, and it is taken as the first HARQ-ACK information to be fed back.

[0096] In this implementation manner, the number of HARQ-ACK bits in the first type of HARQ-ACK codebook can be determined based on dynamic scheduling or the transmission status of the target PDSCH actually transmitted. Here, the transmission status may be understood as that it is necessary to feedback the time position and number of PDSCH transmissions or DCI instructions of HARQ-ACK within the time unit where the target HARQ-ACK codebook is located. Regarding feeding back HARQ-ACK within the specified time unit, if the HARQ-ACK feedback time corresponding to a certain PDSCH transmission or a certain DCI instruction corresponds to a specified time unit (such as an uplink Slot or an uplink Sub-Slot), it may be understood that the HARQ-ACK corresponding to this PDSCH transmission or this DCI instruction is fed back within this specified time unit.

[0097] However, it should be noted that when the target HARQ-ACK codebook corresponds to a codebook that only includes the semi-persistent scheduling HARQ-ACK, the SPS HARQ-ACK bit sequence corresponding to the target HARQ-ACK codebook does not include the HARQ-ACK bit or HARQ-ACK bit sequence corresponding to the target PDSCH, where the HARQ-ACK bit or HARQ-ACK bit sequence corresponding to the target PDSCH may be understood as the target HARQ-ACK information corresponding to the target PDSCH represented in the form of a HARQ-ACK bit or bit sequence. For example, for a codebook such as SPS HARQ-ACK only, when the uplink time unit where its transmission time is located is the second nominal HARQ-ACK feedback time unit, when organizing the SPS HARQ-ACK bit sequence, it can be performed according to the cyclic structure of "Serving cell -> SPS Config -> DL slot", or the SPS HARQ-ACK bit sequence is cyclically determined according to the order specified for a plurality of dimensions including these dimensions of Serving cell, SPS Config, and DL slot / SPS PDSCH, and it is necessary to skip the HARQ-ACK bit / bit sequence corresponding to the SPS PDSCH without feedback 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 situations, for the Type-2 codebook or enhanced Type-2 codebook, when there is an SPS HARQ-ACK, 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 divert the processing when it is SPS HARQ-ACK only, referring to the corresponding description above.

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

[0100] In this embodiment, in order to make the second type of HARQ-ACK codebook compatible with various dynamic scheduling or the transmission status of the actually transmitted PDSCH, in the second type of HARQ-ACK codebook, HARQ-ACK bits corresponding to PDSCH transmissions (including SPS PDSCH) in all possible situations are reserved. Therefore, for the SPS PDSCH without feedback, there may be corresponding HARQ-ACK bits in such a codebook, and due to the limitation of the semi-static HARQ-ACK bit number attribute, these HARQ-ACK bits cannot be reduced, otherwise, it may cause a misunderstanding of the bit number or bit mapping relationship on both sides, for example, in the case of multiplexing with dynamic scheduling HARQ-ACK and DCI detection leakage.

[0101] As can be understood, when there is a target HARQ-ACK codebook corresponding to the target PDSCH, and the target HARQ-ACK codebook corresponds to a second type of HARQ-ACK codebook, the target HARQ-ACK codebook necessarily has HARQ-ACK bits corresponding to the target PDSCH.

[0102] In this case, this embodiment sets the 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] Set the first HARQ-ACK bit to a first predetermined value.

[0104] Here, the first predetermined value may be ACK. That is, assuming that the target PDSCH can always be correctly transmitted at once, therefore, the first HARQ-ACK bit is always set to ACK. Optionally, the first HARQ-ACK bit may be set to NACK.

[0105] Set the first HARQ-ACK bit based on the decoding result of the target PDSCH.

[0106] Here, the value setting of the first HARQ-ACK bit is consistent with the case where the HARQ-ACK disabling scheme is not arranged. For example, when the decoding result is a decoding failure, the value of the first HARQ-ACK bit may be set to NACK, and when the decoding result is a decoding success, the value of the first HARQ-ACK bit may be set to ACK.

[0107] Set the first HARQ-ACK bit according to the case where the target PDSCH transmission has not occurred.

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

[0109] For example, when the target HARQ-ACK codebook corresponds to a Type-3 codebook, the first HARQ-ACK bit is set based on the 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 that of the target PDSCH. That is, assuming that the target PDSCH is an SPS PDSCH, for a Type-3 codebook, if the closest PDSCH transmission of a certain HARQ process is an SPS PDSCH without feedback, the bit setting corresponding to this HARQ process is to set the first HARQ-ACK bit based on the dynamic scheduling PDSCH transmission situation for this HARQ process or the situation of normal SPS PDSCH transmission before this SPS PDSCH without feedback.

[0110] (4) Without any limitation on how the transmitting side sets the first HARQ-ACK bit, the receiving side ignores the value of the first HARQ-ACK bit.

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

[0112] It should be noted that for the Type-1 codebook, only the value indicating the HARQ-ACK bit (in the codebook) corresponding to the PDSCH in the uplink time unit where the HARQ-ACK feedback is located for the codebook transmission is valid. Therefore, for the SPS PDSCH without feedback, there exists a nominal HARQ-ACK feedback time unit corresponding thereto, and the HARQ-ACK bit corresponding to this SPS PDSCH without feedback exists in the Type-1 codebook only when it is the uplink time unit where the Type-1 codebook transmission is located. It should be noted that for a certain uplink time unit (for example, a certain uplink slot or sub-slot), if there is no HARQ-ACK feedback for PDSCH dynamic scheduling or SPS release in addition to the HARQ-ACK for the SPS PDSCH without feedback, the normal Type-1 codebook is not fed back. At this time, reference can be made to the corresponding processing for SPS HARQ-ACK only in the first type of HARQ-ACK codebook. For the SPS PDSCH without feedback, if there is no corresponding nominal HARQ-ACK feedback time unit, it does not correspond to any Type-1 codebook within any uplink time unit.

[0113] For the Type-3 codebook, it is organized based on the HARQ process. Therefore, it is not necessary to pay attention to whether there exists a nominal HARQ-ACK feedback time unit corresponding to the SPS PDSCH without feedback. If the most recent PDSCH transmission of a certain HARQ process is the SPS PDSCH without feedback, it can be considered that the HARQ-ACK bit corresponding to the SPS PDSCH without feedback exists in the Type-3 codebook of the HARQ-ACK including this HARQ process.

[0114] For better understanding, when setting the HARQ-ACK bit to ACK, the bit value may be set to 1, and when setting the HARQ-ACK bit to NACK, the bit value may be set to 0.

[0115] In some situations, for the second type of HARQ-ACK codebook, if there are first HARQ-ACK bits, these first HARQ-ACK bits may be removed from the codebook when the codebook is actually transmitted, and only consider transmitting the (new) codebook composed of other HARQ-ACK bits in the codebook. However, such a method may cause a mismatch in the understanding of the number of bits of the transmission codebooks on both sides when a detection leak occurs on the terminal side of the DCI, thereby potentially affecting the HARQ-ACK feedback performance.

[0116] Based on the above two implementation methods and according to the regulations of the relevant protocol, when the number of uplink control information (UCI) bits carried on the PUCCH is 11 (i.e.,

Number

[0117] The calculation of the PUCCH power control variable for different codebook types will be described below.

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

[0119] (2) For the second type of HARQ-ACK codebook, since the Type-3 codebook does not consider the situation where the current UCI bit number 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 the Type-1 codebook, the PUCCH power control variable corresponding to the target HARQ-ACK codebook (corresponding to the Type-1 codebook) can be calculated by the following (21) or (22).

[0121] (21) When calculating the PUCCH power control variable, incorporate it into the PDSCH count of the received target PDSCH. In this calculation method, the calculation of the PUCCH power control variable n HARQ-ACK considers the first HARQ-ACK bits corresponding to SPS PDSCH without feedback, or considers SPS PDSCH without feedback or the TB (transport block) or CBG (codeblock group) carried thereon. Its calculation method can draw on the conventional protocol regulations.

[0122] Note that 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. Specifically, reference may be made to the relevant description above. To avoid repetition of the description, it will not be elaborated here any further.

[0123] (22) When calculating the PUCCH power control variable, the target PDSCH is not considered (or the SPS PDSCH without feedback is excluded, that is, the SPS PDSCH without feedback is not incorporated into the PDSCH or the TB count). In this calculation method, for the PUCCH power control variable n HARQ-ACK the calculation may not consider the first HARQ-ACK bit corresponding to the SPS PDSCH without feedback, or may not consider the SPS PDSCH without feedback or the TB (transport block) or CBG (code block group) carried thereon, that is, it may be considered to exclude it when calculating the PUCCH power control variable.

[0124] Note that the above setting method of the first HARQ-ACK bit may also be a method of setting the first HARQ-ACK bit according to the situation where the target PDSCH transmission has not occurred. Specifically, reference may be made to the relevant description above. To avoid repetition of the description, it will not be elaborated here any further.

[0125] In this Example 3, for the target PDSCH, based on the transmission time of the target PDSCH, the target HARQ-ACK codebook corresponding to the target PDSCH and the PUCCH power control variable are determined, whereby the communication performance can be ensured.

[0126] Example 4 This Example 4 describes the implementation process of S310 when the predetermined operation is an operation for determining the application of the first rule.

[0127] In the first embodiment, when the target PDSCH is arranged 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 is not applied to the target PDSCH.

[0129] Here, for the target PDSCH, it may be uniformly specified that it includes SPS PDSCH without feedback and does not apply the first rule. Based on the arrangement, this is because there is no actual HARQ-ACK feedback. In some situations, when the target PDSCH does not correspond to the nominal HARQ-ACK feedback time unit, the first rule is not applied to the target PDSCH, that is, since there is no HARQ-ACK feedback time corresponding to the target PDSCH, the first rule cannot be applied. When the target PDSCH corresponds to the nominal HARQ-ACK feedback time unit, the first rule may be applied to the target PDSCH.

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

[0131] Here, for the target PDSCH, it can be uniformly stipulated to include the SPS PDSCH without feedback, and it 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 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, other methods may be used to determine the corresponding HARQ-ACK feedback time and apply the first rule.

[0132] In some situations, when the target PDSCH corresponds to the nominal HARQ-ACK feedback time unit, the target PDSCH may apply the first rule. In this case, the first rule described above 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 the second nominal HARQ-ACK feedback time unit corresponding to the target PDSCH.

[0133] 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 defined by upper layer signaling configuration or protocol, etc., and is not limited here. As can be understood, when the second nominal HARQ-ACK feedback time unit is the same as the first nominal HARQ-ACK feedback time unit in Example 1, the determination process of the second nominal HARQ-ACK feedback time unit can refer to the relevant description regarding the first nominal HARQ-ACK feedback time unit in Example 1, and will not be further described here.

[0134] In the 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 target PDSCH does not apply the first rule.

[0136] As can be understood, for the target PDSCH, the pre-defined HARQ-ACK feedback position cannot be actually fed back. 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 based on the conclusion that it is relaxed according to the OoO requirement for HARQ-ACK retransmission in NR-U (that is, the OoO requirement is only applied to the assigned initial HARQ-ACK transmission occasion assigned to the HARQ-ACK), there is no need to apply the OoO rule (that is, the first rule) either.

[0137] (2) The target PDSCH applies the first rule.

[0138] For better understanding, the target PDSCH applies the out-of-order (OoO) rule between PDSCH reception and HARQ-ACK feedback. At this time, the second feedback time for applying the OoO rule can be determined by any one of the following methods (1)-(3). 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 the first time indicated by the predetermined indication information. Here, the transmission time is the end time of the transmission of the target PDSCH, or the transmission time is the time unit in which the end time of the transmission of the target PDSCH is located.

[0140] (2) Determine the second feedback time based on the transmission time and the feedback delay time length. 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 the second nominal HARQ-ACK feedback time unit, determine the second feedback time based on the second nominal HARQ-ACK feedback time unit.

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

[0143] Here, when the target PDSCH is arranged without target HARQ-ACK information feedback and is arranged 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, determining the activation of the target DRX timer may include any one of the following (1)-(4).

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

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

[0147] (3) After receiving the target PDSCH, activate the drx-HARQ-RTT-TimerDL, and when the drx-HARQ-RTT-TimerDL times out and the first HARQ process fails to decode successfully, activate the drx-RetransmissionTimerDL.

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

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

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

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

[0152] (c) Determine 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 nominal HARQ-ACK feedback time unit, determine the third feedback time based on the second nominal HARQ-ACK feedback time unit.

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

[0155] Based on each of the above examples and based on the differences in the predetermined operations, the implementation process of the communication processing method provided by this embodiment may include one or more of Examples 1-5 above. For example, when the predetermined 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 implementation process of the communication processing method may include the implementation methods in Example 1 and Example 2, and this embodiment does not limit this.

[0156] Note that in the communication processing method 300 provided by this embodiment, a series of adaptive solutions are introduced for different target PDSCHs and / or predetermined operations to ensure communication performance.

[0157] For example, when adopting a HARQ-ACK disabling solution for a certain SPS Config configuration, a series of adaptation solutions are introduced for functions and processes that depend on or are related to HARQ-ACK feedback, so as to ensure that the HARQ-ACK disbaling solution can be fully applied and achieve the goal of reducing the SPS HARQ-ACK feedback load.

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

[0159] It should be noted that in each of the above embodiments, each communication device (including the terminal-side device and the 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 executes a predetermined operation based on the transmission time of the target PDSCH, the protocol or configuration corresponding to the network-side device corresponding to the terminal-side device is preset so that the network-side device can understand the operation executed by the terminal-side device, thereby ensuring the smooth execution of the communication process.

[0160] In addition, the communication processing method according to the embodiments of the present application may be an execution body that is a communication processing device, or a control module for executing the communication processing method in this communication processing device. In the embodiments of the present application, taking the communication processing device executing the communication processing method as an example, the communication processing device according to the embodiments of the present application is described.

[0161] As shown in FIG. 4, it is a block diagram of a communication processing apparatus 400 according to an exemplary embodiment of the present application. The apparatus includes an execution module 410 for executing a predetermined operation based on the transmission time of a target physical downlink shared channel PDSCH. Here, the target PDSCH is arranged without target hybrid automatic repeat request acknowledgment HARQ-ACK information feedback, or there is a feedback delay in the target HARQ-ACK information corresponding to the target PDSCH. The predetermined operation includes determining whether the target PDSCH corresponds to a nominal HARQ-ACK feedback time unit, determining the activation time of a target MAC CE, where the target MAC CE is carried on the target PDSCH, determining a target HARQ-ACK codebook corresponding to the target PDSCH, determining the application of a first rule, where the first rule represents a timing relationship requirement between the target PDSCH and the feedback time corresponding to the target HARQ-ACK information, and determining the activation of a target discontinuous reception DRX timer, where the target DRX timer corresponds to a first HARQ process, and the first HARQ process corresponds to the target PDSCH, including at least one of them.

[0162] As 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 not corresponding to a first nominal HARQ-ACK feedback time unit or the target PDSCH corresponding to the first nominal HARQ-ACK feedback time unit.
