[0030] The network side device 110 and the terminal device 120 communicate with each other via some air interface technology, such as a Uu interface.

[0031] For example, there are two communication scenarios between the network device 110 and the terminal device 120: uplink communication scenario and downlink communication scenario. Uplink communication refers to sending signals to the network device 110; downlink communication refers to sending signals to the terminal device 120.

[0032] The terminal device 120 and the terminal device 130 communicate with each other via some air interface technology, such as a Uu interface.

[0033] In some embodiments, there are two communication scenarios between terminal device 120 and terminal device 130: a first sideline communication scenario and a second sideline communication scenario. The first sideline communication refers to sending signals to terminal device 130, while the second sideline communication refers to sending signals to terminal device 120.

[0034] Terminal device 120 and terminal device 130 are both within the network coverage and located in the same cell, or terminal device 120 and terminal device 130 are both within the network coverage but located in different cells, or terminal device 120 is within the network coverage but terminal device 130 is outside the network coverage.

[0035] The technical solutions provided in the embodiments of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Advanced Long Term Evolution (LTE-A) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G mobile communication system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum) system.

[0037] In related art, the following enhancements are made to the authorization-based transmission of configurations:

[0038] 1) Multiple CG PUSCH transmissions within a single CG PUSCH configuration period;

[0039] 2) The UE dynamically indicates unused CG PUSCH opportunities based on uplink control information (UCI), such as CG-UCI or new UCI.

[0040] In the above scheme, when there is one CG resource in a CG cycle, or when there are multiple CG resources in a CG cycle, there is a corresponding HARQ process for each CG resource position.

[0041] However, the above solution does not consider the situation where a CG cycle has multiple CG resource occasions. Optionally, the HARQ processes of different CG occasions in a CG cycle can be the same or different. When a CG cycle has one CG resource, or when a CG cycle has multiple CG resources, it is unclear how the CG occasion selects or uses the HARQ process for a certain CG occasion.

[0042] This solution is applicable to the case of CG transmission, and may also be applicable to the case of dynamic uplink grant (Dynamic Uplink Grant, DG) transmission, and may also be applicable to the case of DG+CG transmission.

[0043] For example, there are multiple CG transmission opportunities or multiple CG PUSCHs in one CG cycle.

[0044] For example, a CG period has one or more CG transmission opportunities or CG PUSCHs. Also, there are one or more CG configurations, and different CG configurations correspond to different CG indexes.

[0045] For example, multiple DG PUSCH transmissions are scheduled within a period of time or in one DCI.

[0046] For example, within a period of time, there is a DCI that schedules one or more DG PUSCH transmissions and activates or indicates one or more CG PUSCH transmissions. Optionally, the period of time is not related to the CG period. Optionally, the period of time can be one or more CG periods.

[0047] For example, within a period of time, there are one or more CG PUSCH transmissions, and at the same time, DCI schedules one or more DG PUSCH transmissions. Optionally, the period of time is not related to the CG period. Optionally, the period of time can be one or more CG periods.

[0048] For example, a DCI schedules one or more DG PUSCH transmissions and activates or indicates one or more CG PUSCH transmissions. Optionally, the activated or indicated CG PUSCH may be for one or more CG periods.

[0049] For example, there are one or more CG PUSCH transmissions, and the DCI schedules one or more DG PUSCH transmissions. Optionally, the one or more CG PUSCHs may be of one or more CG periods. Optionally, the one or more CG PUSCHs may be of the same CG index or of different CG indices.

Alternatively, the CG transmission, the HARQ performs the selection, and the CG resource usage / processing is handled by the MAC and physical layers.

[0235] For example, the above-mentioned selection or determination of the HARQ process, or the selection or determination of the HARQ process of the uplink grant, or the selection or determination of the HARQ process corresponding to / available for the CG resource, or the selection or determination of the HARQ process corresponding to / available for each CG occasion of the CG resource, or the selection or determination of the HARQ process corresponding to / available for the current CG resource may include at least one of the following:

[0243] 3) Optionally, even if the CGT and / or CGRT of a HARQ process has not timed out, the HARQ process may be considered available for the current PUSCH. This available HARQ process is one for which the first timer has timed out or is not running. Alternatively, the gap is greater than or equal to X. Optionally, the duration of the first timer may be less than the CGT duration.

[0244] 4) Optionally, the first HARQ process is a HARQ process with a HARQ process conflict, or a HARQ process that is occupied, or a HARQ process that is unavailable / unselectable.

[0245] 5) Optionally, the first HARQ process or the unavailable HARQ process is a HARQ process with a gap less than or equal to X. Optionally, the HARQ process with a gap greater than X is not the first HARQ process or is an available HARQ process. Optionally, corresponding to the HARQ process with a gap greater than X, when the HARQ process is selected for current PUSCH transmission, or is selected for HARQ transmission with a gap greater than X, if CGT and / or CGRT are configured, or CGT and / or CGRT are running, CGT and / or CGRT may be stopped. Optionally, the UE stops CGT and / or CGRT in the case of the above-mentioned selection of the HARQ process, or in the case of PUSCH transmission or start of transmission, or in the case of MAC PDU transmission of the HARQ process or submission to the lower layer. Optionally, at the moment of stopping CGT and / or CGRT, or when selecting a HARQ process, or when transmitting or starting PUSCH transmission, or when transmitting or delivering MAC PDU of the HARQ process to a lower layer, the UE counts or recounts the gap, or initializes the gap count, or clears the gap to 0.

[0246] 6) Optionally, the maintenance or calculation of the gap may be implemented by the MAC layer or the physical layer. Optionally, the determination of the relationship between the gap and X may be implemented by the MAC layer or the physical layer. Optionally, the MAC layer or the physical layer may determine whether a HARQ process is available or whether it is the first HARQ process. Optionally, the maintenance and / or related determination of the first timer may be performed by the physical layer and / or the MAC layer.

[0247] Optionally, X is a first time, and the first time is a time interval or a time threshold. Optionally, the first time is given by one of RRC configuration, pre-definition, and pre-configuration. Optionally, the first time is a demodulation and / or rescheduling time.

[0248] Optionally, gap is the time interval between the current PUSCH and the previous PUSCH using the same HPI. Furthermore, the current PUSCH may be a CG PUSCH or a CG occasion. Furthermore, the previous PUSCH using the same HPI is a CG PUSCH or a CG occasion (in this case, if the previous PUSCH is DG, the HARQ process of the corresponding HPI is available, or the HARQ process of the corresponding HPI can be used in the current PUSCH, or the HARQ process of the corresponding HPI can be used to transmit a new MAC PDU, or the MAC PDU in the HARQ process of the corresponding HPI can be overwritten).

[0249] Optionally, the gap includes the interval between the time slot where the end symbol of the previous PUSCH (such as the second PUSCH) is located and the time slot where the end symbol of the current PUSCH (such as the first PUSCH) is located. For example, the end symbol of the second PUSCH is in slot n, and the time slot where the end symbol of the first PUSCH is located is not earlier than slot n+x, and x is a predetermined value, then the HPI can be used by the first PUSCH. For another example, the end symbol of the first PUSCH is in slot m, and the time slot where the end symbol of the second PUSCH is located is not later than slot mx, and x is a predetermined value, then the HPI can be used by the first PUSCH. For another example, the end symbol of the first PUSCH is in slot m, and there is no second PUSCH in the x slots before slot m (or the terminal is not expected to send the second PUSCH in the x slots before slot m), and x is a predetermined value, then the HPI can be used by the first PUSCH. For another example, the end symbol of the second PUSCH is in slot n, the terminal does not send the first PUSCH within x slots after slot n (or the terminal is not expected to send the first PUSCH within x slots after slot n), and x is a predetermined value, then the HPI can be used by the first PUSCH.

[0250] Optionally, the gap is the interval between the time domain symbol occupied by the previous PUSCH (such as the second PUSCH) and the time domain symbol occupied by the current PUSCH (such as the first PUSCH). That is, the interval between the starting or ending position (symbol P) of the second PUSCH and the starting or ending position (symbol Q) of the first PUSCH, and x is a predetermined value. For example, if the symbol Q is not earlier than the xth symbol after the symbol P, the HPI can be used by the first PUSCH. For another example, if the symbol P is not later than the xth symbol before the symbol Q, the HPI can be used by the first PUSCH. For another example, if there is no second PUSCH within the x symbols before the symbol Q (or the terminal is not expected to send the second PUSCH within the x symbols before the symbol Q), the HPI can be used by the first PUSCH. For another example, if the terminal does not send the first PUSCH within x symbols after the symbol P (or the terminal is not expected to send the first PUSCH within x symbols after the symbol P), the HPI can be used by the first PUSCH.

[0251] Alternatively, the starting point of the gap is the starting or ending position of the CG of the previous same HPI process, and the ending position of the gap is the moment before the start or starting moment of the CG of the next HARQ process of the same HPI.

[0252] Alternatively, the first HARQ process or the unavailable HARQ process is a HARQ process whose first timer has not timed out or is running. The non-first HARQ process or the available HARQ process is a HARQ process whose first timer has timed out or is not running. The first timer is configured by network RRC signaling. The first timer configuration includes at least the first timer duration. The first timer is for the CG configuration and / or HARQ process. The first timer for a certain HARQ process is started when the HARQ process is selected or transmitted, or the MAC PDU of the HARQ process is packaged / transmitted / delivered to the physical layer. The first timer is a new timer. When the CGT times out, the first timer is stopped.

[0253] Optionally, when the physical layer determines that a certain HARQ process is unavailable or is the first process, for example, the physical layer indicates the MAC layer the information (i.e., the information that a certain HARQ process is unavailable or is the first process), or the physical layer indicates the MAC layer which HARQ processes are available or which HARQ processes are not the first HARQ process, or the physical layer notifies the MAC layer of the candidate HARQ processes other than the unavailable HARQ process or the first HARQ process.

[0254] If the candidate HARQ process for the CG resource or CG occasion is one, or if the candidate HARQ process for the CG resource or CG occasion is calculated according to a formula, the UE can determine whether to use the first HARQ process based on the first indication information, or determine whether the candidate HARQ process is an available HARQ process. Further including the following 1) to 3).

[0255] 1) Optionally, the UE selects or determines whether to use the first HARQ process based on the first indication information, or determines whether to give low priority to the first HARQ process, or determines whether to give priority to a HARQ process other than the first HARQ process, or determines whether the candidate HARQ process is an available HARQ process.

[0256] 2) Optionally, the first HARQ process is a HARQ process with a HARQ process conflict, or a HARQ process that is occupied, or a HARQ process that is unavailable / unselectable.

[0257] 3) Optionally, the first HARQ process or the unavailable HARQ process is a HARQ process with a gap smaller than or equal to X. Optionally, the HARQ process with a gap greater than X is not the first HARQ process or is an available HARQ process.

[0258] Optionally, X is a first time, and the first time is a time interval or a time threshold. Optionally, the first time is given by one of RRC configuration, pre-definition, and pre-configuration. Optionally, the first time is a demodulation and / or rescheduling time.

[0259] Optionally, gap is the time interval between the current PUSCH and the previous PUSCH using the same HPI. Furthermore, the current PUSCH may be a CG PUSCH or a CG occasion. Furthermore, the previous PUSCH using the same HPI is a CG PUSCH or a CG occasion (in this case, if the previous PUSCH is DG, the HARQ process of the corresponding HPI is available, or the HARQ process of the corresponding HPI can be used in the current PUSCH, or the HARQ process of the corresponding HPI can be used to transmit a new MAC PDU, or the MAC PDU in the HARQ process of the corresponding HPI can be overwritten).

[0260] Alternatively, the starting point of the gap is the starting or ending position of the CG of the previous same HPI process, and the ending position of the gap is the moment before the start or starting moment of the CG of the next HARQ process of the same HPI.

[0261] Alternatively, the first HARQ process or the unavailable HARQ process is a HARQ process whose first timer has not expired or is currently running. A non-first HARQ process or an available HARQ process is a HARQ process whose first timer has expired or is not currently running. The first timer is configured by network RRC signaling. The first timer configuration includes at least the first timer duration. The first timer is specific to the CG configuration and / or HARQ process. The first timer for a specific HARQ process is started when the HARQ process is selected or transmitted, or when the MAC PDU of the HARQ process is packaged / transmitted / delivered to the physical layer. The first timer is a new timer. If the CGT expires, the first timer is stopped. Optionally, for a HARQ process whose first timer has expired or is not currently running, if the CGT and / or CGRT is configured or is currently running, the CGT and / or CGRT may be stopped when the HARQ process whose first timer has expired or is not currently running is selected for current PUSCH transmission or is selected for HARQ transmission using the HARQ process whose first timer has expired or is not currently running. Optionally, the UE stops the CGT and / or CGRT when selecting a HARQ process, or when transmitting or starting a PUSCH transmission, or when transmitting or delivering a MAC PDU of the HARQ process to a lower layer. Optionally, the UE starts a first timer at the moment of stopping the CGT and / or CGRT, or when selecting a HARQ process, or when transmitting or starting a PUSCH transmission, or when delivering or delivering a MAC PDU of the HARQ process to a lower layer. Optionally, the UE starts / restarts the CGT and / or CGRT when starting the first timer.

[0262] Based on the embodiment shown in FIG3 , in some embodiments, the first resource transmission or processing mode, or the first behavior, includes at least one of the following behaviors:

[0263] Ignore uplink authorization, CG occasion or CG PUSCH;

[0264] discarded or low-priority uplink grant, CG occasion or CG PUSCH;

[0265] Discard or lower-priority unavailable HARQ or uplink grant of the first HARQ process, CG occasion or CG PUSCH;

[0266] Do not generate a corresponding new MAC PDU;

[0267] Do not call reuse and group packaging entities;

[0268] The corresponding MAC PDU is not sent to the lower layer.

[0269] In some embodiments, the execution condition of the first behavior includes:

[0270] The candidate HARQ process for the uplink resource is the first HARQ process or an unavailable HARQ process, or,

[0271] The uplink resource corresponds only to the first HARQ process or an unavailable HARQ process.

[0272] For example, the UE performs the first behavior, or the UE performs the first behavior based on the first indication information.

[0273] For example, the first behavior includes at least one of the following: ignoring the uplink grant or CG occasion or CG PUSCH, giving low priority to the uplink grant or CG occasion or CG PUSCH, giving low priority to the unavailable or first HARQ process uplink grant or CG occasion or CG PUSCH, not generating the corresponding new MAC PDU, not calling the multiplexing and packetization entity, and not delivering the corresponding MAC PDU to the lower layer (such as the physical layer). Furthermore, the first behavior is performed under the following conditions: the first behavior is performed at the MAC layer, and for the first HARQ process or the unavailable HARQ process, the candidate HARQ process of the uplink resource has the first HARQ process or the unavailable HARQ process. Optionally, MAC performs the above-mentioned first behavior based on the information indicated by the physical layer.

[0274] For another example, the first behavior includes at least one of the following: ignoring uplink grant or CG occasion or CG PUSCH, low priority uplink grant or CG occasion or CG PUSCH, low priority uplink resources corresponding to an unavailable HARQ process or the first HARQ process, retaining existing HARQ PDUs in the unavailable or first HARQ process, and ignoring or discarding new / newly received MAC PDUs for the unavailable or first HARQ process. Furthermore, the first behavior is performed under the following conditions: the first behavior is performed at the physical layer, and for the first HARQ process or the unavailable HARQ process, the first HARQ process or the unavailable HARQ process is a candidate HARQ process for the uplink resource.

[0275] Please see the following Ⅰ) to Ⅴ) for details.

[0276] I) For example, if the first timer of a certain HARQ process is running or has not timed out, or the first timer of a certain HARQ process is running or has not timed out for a certain CG occasion, then this HARQ process is an unavailable HARQ process or the first HARQ process.

[0277] II) For example, if the gap corresponding to a certain HARQ process is smaller than X, or the gap corresponding to a certain HARQ process is smaller than X for a certain CG occasion, then this HARQ process is an unavailable HARQ process or the first HARQ process.

[0278] III) For example, for a HARQ process with a gap greater than X, or a HARQ process with a first timer that has expired or is not running, when the HARQ process is selected for current PUSCH transmission, or is selected for HARQ transmission with a gap greater than X, if CGT and / or CGRT is configured, or if CGT and / or CGRT is running, the CGT and / or CGRT may be stopped. Optionally, the UE stops the CGT and / or CGRT when selecting the HARQ process, or when transmitting or starting PUSCH transmission, or when transmitting or delivering a MAC PDU of the HARQ process to lower layers. Optionally, the UE starts the first timer at the moment of stopping the CGT and / or CGRT, or when selecting the HARQ process, or when transmitting or starting PUSCH transmission, or when transmitting or delivering a MAC PDU of the HARQ process to lower layers. Optionally, the UE starts / restarts the CGT and / or CGRT when starting the first timer. Optionally, at the moment of stopping CGT and / or CGRT, or when selecting a HARQ process, or when transmitting or starting PUSCH transmission, or when transmitting or delivering MAC PDU of the HARQ process to a lower layer, the UE counts or recounts the gap, or initializes the gap count, or clears the gap to 0.

[0279] IV) For example, the MAC entity low-prioritizes the first HARQ process or the unavailable HARQ process, or does not select the first HARQ process or the unavailable HARQ process for the corresponding or current CG occasion transmission.

[0280] V) For example, the MAC entity does not generate a new MAC PDU for the first HARQ process or the unavailable HARQ process, or ignores the first HARQ process or the unavailable HARQ process, or does not deliver the MAC PDU of the first HARQ process or the unavailable HARQ process to the lower layer, or does not use the CG resources of the first HARQ process or the unavailable HARQ process, or gives low priority to the uplink resources.

[0281] For example, the physical layer prioritizes the first HARQ process or an unavailable HARQ process, or does not select the first HARQ process or an unavailable HARQ process for the corresponding or current CG occasion transmission. The physical layer informs the MAC layer of the HARQ process information.

[0282] For example, the MAC entity does not generate a new MAC PDU for the first HARQ process or the unavailable HARQ process, or ignores the first HARQ process or the unavailable HARQ process, or does not deliver the MAC PDU of the first HARQ process or the unavailable HARQ process to the lower layer, or does not use the CG resources of the first HARQ process or the unavailable HARQ process, or considers the CG resources of the HARQ process to be of low priority, or does not use the CG resources of the HARQ process. Further, the MAC layer performs this behavior according to the information of the HARQ process informed by the physical layer.

[0283] For example, the physical layer prioritizes the first HARQ process or an unavailable HARQ process, or does not select the first HARQ process or an unavailable HARQ process for the corresponding or current CG occasion transmission. Furthermore, the physical layer ignores / discards the new MAC PDU of the HARQ process, or retains the original MAC PDU, or ignores the CG resources corresponding to the HARQ process, or considers the CG resources of the HARQ process to be of low priority.

[0284] The solution shown in the above embodiments of the present application provides a method for selecting or using HARQ processes, or processing CG resources, when the HARQ processes conflict or the HARQ processes are occupied. This can solve the problem of HARQ process conflicts and avoid the situation where the MAC PDU in the HARQ process that still needs to be used / reserved is flushed.

[0285] For example, please refer to Figure 4, which shows a wireless transmission schematic provided by an exemplary embodiment of the present application. As shown in Figure 4, HPI1 and HPI2 have different time intervals GAP. In CG1, the terminal device transmits HPI2, and in CG2, the terminal device transmits HPI1. In CG3, HPI1 and HPI2 need to be transmitted at the same time. At this time, a HARQ conflict occurs. The terminal device can choose to transmit HPI2 according to the scheme shown in the above embodiment, and not transmit HPI1, thereby avoiding the failure of HPI1 MAC PDU transmission.

[0286] Based on the embodiment shown in FIG. 2 or FIG. 3 , taking the example of the MAC layer performing wireless transmission-related processing according to the selection or use rule of the first hybrid automatic repeat request HARQ process, or according to the first resource transmission or processing mode, the above solution can be implemented as follows:

[0287] S1: The base station sends configuration information to the UE. This configuration information is used for CG transmission, HARQ selection / use, or CG resource use / processing. Optionally, it includes at least one of the following:

[0288] a) This configuration information includes uplink grant resource configuration. Optional:

[0289] i) The uplink grant resource configuration includes one or more PUSCH occasions.

[0290] Optionally, the uplink grant resource configuration includes a CG configuration. A CG period may include one or more CG occasions.

[0291] ii) The uplink grant resource configuration includes the available HARQ processes and, optionally, the number of HARQ processes and / or the HARQ process offset.

[0292] Optionally, the uplink grant resource configuration includes a CG configuration. The HARQ process in this configuration is a HARQ process available for the CG configuration.

[0293] b) The network instructs the UE to provide first indication information, indicating whether to use the first HARQ process selection / usage rule, or to select the HARQ process for transmission using the CG occasion (or the current CG occasion) according to the first HARQ process selection / usage rule. And / or, based on the first indication information, the UE performs the first behavior.

[0294] i) Optionally, the first indication information may be configured via RRC, carried in configuredgrantconfig, or carried in other RRC signaling.

[0295] ii) Optionally, the first indication information may be DCI or MAC CE. Optionally, the DCI may be CG activation / deactivation DCI.

[0296] S2: The UE performs at least one of CG transmission, HARQ selection, and CG resource use / processing according to the network configuration information. Specifically, this may include at least one of the following:

[0297] a) Select or determine the HARQ process, or select or determine the HARQ process for the uplink grant, or select or determine the HARQ process corresponding to / available for the CG resource, or select or determine the HARQ process corresponding to / available for each CG occasion of the CG resource, or select or determine the HARQ process corresponding to / available for the current CG resource. This includes at least one of the following:

[0298] i) The UE selects or determines the HARQ process according to the HARQ calculation formula and / or UE implementation.

[0299] ii) The UE selects or determines the HARQ process based on the LCH priority or the HARQ process priority.

[0300] iii) The UE selects or determines the HARQ process based on the first indication information.

[0301] The above i, ii and iii can be used alone, or at least two of them can be used in combination.

[0302] If the uplink grant, or the candidate HARQ process of the CG resource (or CG occasion) is multiple, or if the uplink grant, or the candidate HARQ process of the CG resource (or CG occasion) is selected by the UE, then the UE selects or determines whether to use the first HARQ process, or determines whether to give low priority to the first HARQ process, or determines whether to give priority to HARQ processes other than the first HARQ process, or determines whether the candidate HARQ process is an available HARQ process, or the UE determines whether to use the HARQ process whose CGT / CGRT has not timed out.

[0303] 1) Further, the UE selects or determines whether to use the first HARQ process based on the first indication information, or determines whether to give low priority to the first HARQ process, or determines whether to give priority to a HARQ process other than the first HARQ process, or determines whether the candidate HARQ process is an available HARQ process, or the UE determines whether to use a HARQ process whose CGT / CGRT has not timed out.

[0304] 2) Optionally, the MAC layer performs the operation or judgment.

[0305] 3) Optionally, even if the CGT and / or CGRT of a HARQ process has not timed out, the HARQ process may be considered available for the current PUSCH. This available HARQ process is one for which the first timer has timed out or is not running. Alternatively, the gap is greater than or equal to X. Optionally, the duration of the first timer may be less than the CGT duration.

[0306] 4) Optionally, the first HARQ process is a HARQ process with a HARQ process conflict, or a HARQ process that is occupied, or a HARQ process that is unavailable / unselectable.

[0307] 5) Optionally, the first HARQ process or the unavailable HARQ process is a HARQ process with a gap less than or equal to X. Optionally, the HARQ process with a gap greater than X is not the first HARQ process or is an available HARQ process. Optionally, for a HARQ process with a gap greater than X, when the HARQ process is selected for current PUSCH transmission, or when the current PUSCH is selected for HARQ transmission with a gap greater than X, if CGT and / or CGRT is configured or is in operation, CGT and / or CGRT may be stopped.

[0308] Optionally, X is a first time, and the first time is a time interval or a time threshold. Optionally, the first time is given by one of RRC configuration, pre-definition, and pre-configuration. Optionally, the first time is a demodulation and / or rescheduling time.

[0309] Optionally, gap is the time interval between the current PUSCH and the previous PUSCH using the same HPI. Furthermore, the current PUSCH may be a CG PUSCH or a CG occasion. Furthermore, the previous PUSCH using the same HPI is a CG PUSCH or a CG occasion (in this case, if the previous PUSCH is DG, the HARQ process of the corresponding HPI is available, or the HARQ process of the corresponding HPI can be used in the current PUSCH, or the HARQ process of the corresponding HPI can be used to transmit a new MAC PDU, or the MAC PDU in the HARQ process of the corresponding HPI can be overwritten).

[0310] Optionally, the gap includes the interval between the time slot where the end symbol of the previous PUSCH (such as the second PUSCH) is located and the time slot where the end symbol of the current PUSCH (such as the first PUSCH) is located. For example: if the end symbol of the second PUSCH is in slot n, the time slot where the end symbol of the first PUSCH is located is not earlier than slot n+x, and x is a predetermined value, then the HPI can be used by the first PUSCH. For another example, if the end symbol of the first PUSCH is in slot m, the time slot where the end symbol of the second PUSCH is located is not later than slot mx, and x is a predetermined value, then the HPI can be used by the first PUSCH. For another example: if the end symbol of the first PUSCH is in slot m, there is no second PUSCH in the x slots before slot m (or the terminal is not expected to send the second PUSCH in the x slots before slot m), and x is a predetermined value, then the HPI can be used by the first PUSCH. For another example, the end symbol of the second PUSCH is in slot n, the terminal does not send the first PUSCH within x slots after slot n (or the terminal is not expected to send the first PUSCH within x slots after slot n), and x is a predetermined value, then the HPI can be used by the first PUSCH.

[0311] Optionally, the gap is the interval between the time domain symbol occupied by the previous PUSCH (such as the second PUSCH) and the time domain symbol occupied by the current PUSCH (such as the first PUSCH). That is, the interval between the starting or ending position (symbol P) of the second PUSCH and the starting or ending position (symbol Q) of the first PUSCH, and x is a predetermined value. For example, if the symbol Q is not earlier than the xth symbol after the symbol P, the HPI can be used by the first PUSCH. For another example, if the symbol P is not later than the xth symbol before the symbol Q, the HPI can be used by the first PUSCH. For another example, if there is no second PUSCH within the x symbols before the symbol Q (or the terminal is not expected to send the second PUSCH within the x symbols before the symbol Q), the HPI can be used by the first PUSCH. For another example, if the terminal does not send the first PUSCH within x symbols after the symbol P (or the terminal is not expected to send the first PUSCH within x symbols after the symbol P), the HPI can be used by the first PUSCH.

[0312] Alternatively, the starting point of the gap is the starting or ending position of the CG of the previous same HPI process, and the ending position of the gap is the moment before the start or starting moment of the CG of the next HARQ process of the same HPI.

[0313] Alternatively, the first HARQ process or the unavailable HARQ process is a HARQ process whose first timer has not timed out or is running. The non-first HARQ process or the available HARQ process is a HARQ process whose first timer has timed out or is not running. The first timer is configured by network RRC signaling. The first timer configuration includes at least the first timer duration. The first timer is for the CG configuration and / or HARQ process. The first timer for a certain HARQ process is started when the HARQ process is selected or transmitted, or the MAC PDU of the HARQ process is packaged / transmitted / delivered to the physical layer. The first timer is a new timer. When the CGT times out, the first timer is stopped.

[0314] The candidate HARQ process for the CG resource or CG occasion is one, or if the candidate HARQ process for the CG resource or CG occasion is calculated according to a formula, the UE can determine whether to use the first HARQ process based on the first indication information, or determine whether the candidate HARQ process is an available HARQ process.

[0315] 1) Further, the UE selects or determines whether to use the first HARQ process based on the first indication information, or determines whether to give low priority to the first HARQ process, or determines whether to give priority to a HARQ process other than the first HARQ process, or determines whether the candidate HARQ process is an available HARQ process.

[0316] 2) Optionally, the first HARQ process is a HARQ process with a HARQ process conflict, or a HARQ process that is occupied, or a HARQ process that is unavailable / unselectable.

[0317] 3) Optionally, the first HARQ process or the unavailable HARQ process is a HARQ process with a gap smaller than or equal to X. Optionally, the HARQ process with a gap greater than X is not the first HARQ process or is an available HARQ process.

[0318] Optionally, X is a first time, and the first time is a time interval or a time threshold. Optionally, the first time is given by one of RRC configuration, pre-definition, and pre-configuration. Optionally, the first time is a demodulation and / or rescheduling time.

[0319] Optionally, gap is the time interval between the current PUSCH and the previous PUSCH using the same HPI. Furthermore, the current PUSCH may be a CG PUSCH or a CG occasion. Furthermore, the previous PUSCH using the same HPI is a CG PUSCH or a CG occasion (in this case, if the previous PUSCH is DG, the HARQ process of the corresponding HPI is available, or the HARQ process of the corresponding HPI can be used in the current PUSCH, or the HARQ process of the corresponding HPI can be used to transmit a new MAC PDU, or the MAC PDU in the HARQ process of the corresponding HPI can be overwritten).

[0320] Alternatively, the starting point of the gap is the starting or ending position of the CG of the previous same HPI process, and the ending position of the gap is the moment before the start or starting moment of the CG of the next HARQ process of the same HPI.

[0321] Alternatively, the first HARQ process or the unavailable HARQ process is a HARQ process whose first timer has not timed out or is running. The non-first HARQ process or the available HARQ process is a HARQ process whose first timer has timed out or is not running. The first timer is configured by network RRC signaling. The first timer configuration includes at least the first timer duration. The first timer is for the CG configuration and / or HARQ process. The first timer for a certain HARQ process is started when the HARQ process is selected or transmitted, or the MAC PDU of the HARQ process is packaged / transmitted / delivered to the physical layer. The first timer is a new timer. When the CGT times out, the first timer is stopped. Optionally, corresponding to the HARQ process that has timed out or is not running with the first timer, when the HARQ process is selected for current PUSCH transmission, or the current PUSCH is selected for HARQ transmission with timed out or not running with the first timer, if CGT and / or CGRT are configured, or CGT and / or CGRT are running, CGT and / or CGRT can be stopped.

[0322] b) The UE performs the first behavior, or the UE performs the first behavior based on the first indication information. The first behavior includes at least one of the following: ignoring the uplink grant or CG occasion or CG PUSCH, giving low priority to the uplink grant or CG occasion or CG PUSCH, giving low priority to the unavailable or first HARQ process uplink grant or CG occasion or CG PUSCH, not generating the corresponding new MAC PDU, not calling the multiplexing and packetization entity, and not delivering the corresponding MAC PDU to the lower layer (such as the physical layer). Furthermore, the first behavior is performed under the following conditions: the first behavior is performed at the MAC layer, and for the first HARQ process or the unavailable HARQ process, the candidate HARQ process of the uplink resource exists as the first HARQ process or the unavailable HARQ process.

[0323] i) For example, if the first timer of a certain HARQ process is running or has not timed out, or the first timer of a certain HARQ process for a certain CG occasion is running or has not timed out, then this HARQ process is an unavailable HARQ process or the first HARQ process.

[0324] ii) For example, if the gap corresponding to a certain HARQ process is smaller than X, or the gap corresponding to a certain HARQ process is smaller than X for a certain CG occasion, then this HARQ process is an unavailable HARQ process or the first HARQ process.

[0325] iii) For example, for a HARQ process corresponding to a gap greater than X, or a HARQ process whose first timer has timed out or is not running, when the HARQ process is selected for current PUSCH transmission, or when the current PUSCH is selected for HARQ transmission with a gap greater than X, if CGT and / or CGRT is configured, or CGT and / or CGRT is running, CGT and / or CGRT can be stopped.

[0326] iv) For example, the MAC entity low-prioritizes the first HARQ process or the unavailable HARQ process, or does not select the first HARQ process or the unavailable HARQ process for the corresponding or current CG occasion transmission.

[0327] v) For example, the MAC entity does not generate a new MAC PDU for the first HARQ process or the unavailable HARQ process, or ignores the first HARQ process or the unavailable HARQ process, or does not deliver the MAC PDU of the first HARQ process or the unavailable HARQ process to the lower layer, or does not use the CG resources of the first HARQ process or the unavailable HARQ process, or gives low priority to the uplink resources.

Furthermore, the first behavior is performed under the following conditions: the first behavior is performed at the MAC layer, and for the first HARQ process or the unavailable HARQ process, the candidate HARQ process for the uplink resource exists as the first HARQ process or the unavailable HARQ process.

[0370] Furthermore, according to the information indicated by the physical layer (as in step b), the MAC executes the first behavior.

[0371] ii) Optionally, the first behavior includes at least one of the following: ignoring the uplink grant or CG occasion or CG PUSCH, giving low priority to the uplink grant or CG occasion or CG PUSCH, giving low priority to the uplink resources corresponding to the unavailable HARQ process or the first HARQ process, retaining the existing HARQ PDU in the unavailable or first HARQ process, and ignoring or discarding the new / newly received MAC PDU for the unavailable or first HARQ process. Furthermore, the first behavior is performed under the following conditions: the first behavior is performed at the physical layer, and for the first HARQ process or the unavailable HARQ process, the first HARQ process or the unavailable HARQ process is a candidate HARQ process for the uplink resource.

[0372] iii) For example, if the first timer of a certain HARQ process is running or has not timed out, or the first timer of a certain HARQ process is running or has not timed out for a certain CG occasion, then this HARQ process is an unavailable HARQ process or the first HARQ process.

[0373] iv) For example, if the gap corresponding to a certain HARQ process is smaller than X, or the gap corresponding to a certain HARQ process is smaller than X for a certain CG occasion, then this HARQ process is an unavailable HARQ process or the first HARQ process.

[0374] For example, for a HARQ process with a gap greater than X, or a HARQ process whose first timer has timed out or is not running, when the HARQ process is selected for current PUSCH transmission, or the current PUSCH is selected for HARQ transmission, if CGT and / or CGRT are configured, or CGT and / or CGRT are running, CGT and / or CGRT can be stopped.

[0375] v) For example, the physical layer prioritizes the first HARQ process or an unavailable HARQ process, or does not select the first HARQ process or an unavailable HARQ process for the corresponding or current CG occasion transmission. The physical layer informs the MAC layer of the HARQ process information.

[0376] vi) For example, the MAC entity does not generate a new MAC PDU for the first HARQ process or the unavailable HARQ process, or ignores the first HARQ process or the unavailable HARQ process, or does not deliver the MAC PDU of the first HARQ process or the unavailable HARQ process to the lower layer, or does not use the CG resources of the first HARQ process or the unavailable HARQ process, or considers the CG resources of the HARQ process to be of low priority, or does not use the CG resources of the HARQ process. Further, the MAC layer performs this behavior based on the information of the HARQ process notified by the physical layer.

[0377] vii) For example, the physical layer deprioritizes the first HARQ process or an unavailable HARQ process, or does not select the first HARQ process or an unavailable HARQ process for the corresponding or current CG occasion transmission. Furthermore, the physical layer ignores / discards the new MAC PDU of the HARQ process, or retains the original MAC PDU, or ignores the CG resources corresponding to the HARQ process, or considers the CG resources of the HARQ process to be of low priority.
