Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0098] In the field of communication technology, contention resolution diversity slotted ALOHA (CRDSA) technology is a technology for reducing the uplink collision probability of a contention channel and improving the uplink capacity. A terminal generates multiple uplink transmissions by duplicating an uplink transmission, and then transmits the multiple uplink transmissions at different times. The network receives any one of the uplink transmissions, and thus succeeds in receiving, thereby reducing the collision failure probability.

[0099] In some embodiments, because the terminal transmits at least two copies of the same uplink transmission, the collision probability is increased to some extent, and thus interference cancellation technology needs to be used. The process is described below in conjunction with FIG. 1B. FIG. 1B is a timing diagram of uplink transmissions received by the network device. For example, a terminal transmits two copies of an uplink transmission PK3, one of which does not collide, and the network device can correctly parse. The other copy of the uplink transmission PK3 collides with a copy of an uplink transmission PK2 transmitted by another terminal. Then the network device can use the correctly parsed PK3 to perform interference cancellation on the position of the other copy of the uplink transmission PK3, so that the network device can correctly parse the uplink transmission PK2 transmitted by the other terminal. Then the network device can use the parsed PK2 to perform interference cancellation on the position of the other copy of the uplink transmission PK2, parse the uplink transmission PK1, and so on, until all uplink transmissions that can be parsed are parsed, such as PK4, PK5, and PK6 in the figure.

[0100] When multiple uplink transmissions are transmitted using configured grant (CG) resources, the Hybrid Automatic Repeat Request (HARQ) process corresponding to the CG resources may be determined based on the time domain position of the CG, and thus the HARQ processes used for transmitting multiple uplink transmissions may be different. The present disclosure mainly aims to solve the problem of how the terminal processes when the terminal receives a Physical Downlink Control Channel (PDCCH) scheduling for one of the HARQ processes when the HARQ processes used for transmitting multiple uplink transmissions are different.

[0101] The present disclosure proposes to determine the target timer to be processed according to the content of the information received by the terminal, and then process the target timer associated with the HARQ process of the uplink transmission, considering the different purposes of the PDCCH scheduling.

[0102] Optionally, when the terminal receives PDCCH new transmission scheduling for one HARQ process, the terminal should stop the configured grant timer (ConfiguredGrantTimer), the discontinuous reception (DRX) HARQ round trip time timer (RTT Timer), and the DRX HARQ retransmission timer (retransmissionTimer) of other HARQ processes, so that the HARQ processes used for sending other uplink transmissions can be used for new transmission, and there is no need to listen to retransmission scheduling.

[0103] Optionally, the terminal can also clear the buffer of one of the HARQ processes, and can also clear the buffers of other HARQ processes at the same time.

[0104] Optionally, in order to solve the problem of using different HARQ processes for different uplink transmission sending, the HARQ process selection method in new radio unlicensed (NR-U) can be borrowed, that is, the terminal can select a HARQ process from a HARQ process pool. Different uplink packets can select the same HARQ process. At this time, not all uplink transmission sending needs to carry the HARQ process identification (ID), only the first uplink transmission needs to carry the HARQ process ID.

[0105] The transmission method and apparatus provided by the present disclosure will be described in detail below with reference to the accompanying drawings.

[0106] FIG. 2A is an interaction schematic diagram of a transmission method according to an embodiment of the present disclosure. As shown in FIG. 2A, the present embodiment relates to a transmission method, and the method comprises:

[0107] Step S2101: determining at least one HARQ process from a HARQ process pool.

[0108] In some embodiments, the HARQ process pool is configured for the terminal 101 by the network device 102 in advance.

[0109] In some embodiments, the terminal 101 can randomly select one or more HARQ processes from the HARQ process pool for transmitting multiple uplink transmissions.

[0110] In some embodiments, the terms "uplink transmission", "uplink sending", "uplink duplicated packet", "uplink data packet", "uplink packet", "uplink information" and the like can refer to data and / or control signaling sent in uplink, and thus they can be replaced with each other in some cases.

[0111] In some embodiments, the terminal 101 can first duplicate the to-be-sent uplink transmission to obtain multiple uplink transmissions.

[0112] In some embodiments, the multiple uplink transmissions can carry the same content, which can be the same effective information carried in the multiple uplink transmissions. For example, the multiple uplink transmissions can have the same payload, the same MAC PDU (Protocol Data Unit) or the same MAC SDU (service Data Unit).

[0113] In some embodiments, the terminal can send the multiple uplink transmissions to the network device using the configured resources.

[0114] In some embodiments, the multiple uplink transmissions can be transmitted using multiple configured resources.

[0115] In some embodiments, the configured resources can be CG (ConfiguredGrant) resources.

[0116] For example, the configured resources can be CG resources configured based on RRC (Radio Resource Control), or CG resources activated based on DCI (Downlink Control Information), that is, ConfiguredGrantType 1 resources and ConfiguredGrantType 2 resources. Alternatively, the configured resources can be PUR (preconfigured uplink Resource) or other types of preconfigured resources.

[0117] In some embodiments, the ConfiguredGrant resources are resources used in the inactive state or the connected state.

[0118] In some embodiments, the CG resources used in the inactive state can be CG resources for small data packet transmission, or CG resources configured in the connected state.

[0119] In some embodiments, the terminal can randomly select multiple CG resources in the resource pool configured by the network device.

[0120] In some embodiments, at least one of the time domain, frequency domain and / or code domain resources among the multiple CG resources selected by the terminal 101 can be discontinuous.

[0121] In some embodiments, the code domain resource can be a Demodulation Reference Signal (DMRS).

[0122] For example, the multiple CG resources can be multiple CG resources discontinuous in time domain, or can be resources corresponding to different DMRS, and the like, which are not limited in the present disclosure.

[0123] In some embodiments, if the time domain positions of the multiple CG resources selected by the terminal 101 are the same, and the frequency domain and / or code domain resources are different, the terminal 101 is required to send multiple uplink transmissions to the network device at the same time. In order to ensure that each uplink transmission can be reliably sent, the terminal 101 needs to provide a larger transmission power. In order to avoid such a situation as much as possible, the terminal 101 can select CG resources corresponding to different time domain occasions when selecting CG resources for sending multiple uplink transmissions.

[0124] In some embodiments, the terminal 101 can select a HARQ process corresponding to the CG resource from the HARQ process pool after selecting the CG resource for sending multiple uplink transmissions.

[0125] In some embodiments, the terminal 101 can also select CG resources corresponding to the same HARQ process and corresponding to different time domain occasions when selecting CG resources. That is, the terminal 101 finally uses the same HARQ process to successively send multiple uplink transmissions carrying the same data to the network device 102.

[0126] In some embodiments, if the time domain positions of the multiple CG resources selected by the terminal 101 are different, and the HARQ process has a one-to-one mapping relationship with the time domain position of the configured resource, the corresponding HARQ process can be the same or different when the terminal 101 selects different configured resources to send multiple duplicated packets.

[0127] In some embodiments, the terminal can select different HARQ processes from the HARQ process pool to transmit multiple uplink transmissions respectively.

[0128] In some embodiments, the uplink transmission can be a MAC PDU or a MAC SDU.

[0129] In some embodiments, the number of uplink transmissions can be configured by the system or configured by the network device. For example, the number of uplink transmissions can be indicated in the CG configuration or indicated in the scheduling DCI of the CG.

[0130] In some embodiments, the configured resources can be shared by multiple terminals or the network device can configure the configured resources for each terminal to send the multiple uplink transmissions.

[0131] In some embodiments, the terminal can be a Non Terrestrial Network (NTN) terminal or a Terrestrial Network (TN) terminal.

[0132] At step S2102, the terminal sends the multiple uplink transmissions through at least one HARQ process.

[0133] In some embodiments, the terminal 101 can send at least one of the multiple uplink transmissions through at least one HARQ process to the network device 102.

[0134] In some embodiments, the terminal 101 can send all the multiple uplink transmissions through the first HARQ process. Thus, the complexity of scheduling the multiple uplink transmissions by the network device 102 is reduced.

[0135] In some embodiments, when the terminal 101 sends only part of the multiple uplink transmissions through the first HARQ process, the terminal 101 also needs to select the HARQ processes corresponding to the other uplink transmissions from the process pool for sending the other uplink transmissions.

[0136] In some embodiments, the at least one uplink transmission contains the identification of the HARQ processes corresponding to the multiple uplink transmissions. Thus, after receiving the at least one uplink transmission, the network device can determine the HARQ processes used by all other uplink transmissions carrying the same content, thereby ensuring that the network device can perform reliable interference cancellation.

[0137] In some embodiments, each uplink transmission contains the identification of the HARQ processes corresponding to the multiple uplink transmissions. Thus, after receiving any one uplink transmission, the network device can determine the HARQ processes used by all other uplink transmissions carrying the same content, thereby ensuring that the network device can perform reliable interference cancellation.

[0138] In some embodiments, the one designated uplink transmission contains the identification of the HARQ processes corresponding to the multiple uplink transmissions. The terminal carries the identification of the HARQ processes used by all the uplink transmissions in one designated uplink transmission, thereby reducing the amount of resources occupied by the transmission of the HARQ process identification while ensuring that the network device can perform reliable interference cancellation.

[0139] In some embodiments, the terminal 101 can determine the one designated uplink transmission according to a protocol agreement.

[0140] In some embodiments, the protocol can agree that the first (transmitted) uplink transmission in the multiple uplink transmissions is the one designated uplink transmission. For example, the protocol can agree that the first transmitted uplink transmission in the multiple uplink transmissions is the one designated uplink transmission, or the protocol can agree that the last transmitted uplink transmission in the multiple uplink transmissions is the one designated uplink transmission, and the present disclosure does not limit this.

[0141] In some embodiments, the terminal 101 can also determine the one designated uplink transmission according to an indication of the network device 102.

[0142] In some embodiments, the terminal 101 can carry the HARQ process identification in the uplink control information (UCI) of the uplink transmission.

[0143] In some embodiments, the terminal 101 can use some orthogonal frequency division multiplexing (OFDM) symbols on some resource blocks (RBs) in the configured configuration resources for UCI transmission, such as using OFDM symbols that are not occupied by UCI.

[0144] In some embodiments, the network device 102 can configure different resources for UCI transmission for different terminals 101, so as to avoid UCI collision and thus be unable to be parsed. In this way, even if one uplink transmission of a terminal collides with the uplink transmissions of other terminals, the UCI can still be parsed. Then, the network device can use the HARQ Process ID obtained based on the received one uplink transmission to determine the HARQ Process used by the other uplink transmissions.

[0145] Step S2103: transmitting the first information.

[0146] In some embodiments, the network device 102 transmits the first information to the terminal 101.

[0147] In some embodiments, the first information is associated with the first HARQ process.

[0148] In some embodiments, the first HARQ process is one of the at least one HARQ process.

[0149] In some embodiments, the first information can be information for scheduling the first HARQ process. For example, the first information can be scheduling of a new transmission of the first HARQ process, or scheduling of a retransmission of the first HARQ process.

[0150] In some embodiments, the first information can also be downlink feedback information for the first HARQ process. For example, the first information can be acknowledgement (ACK) information for the first HARQ process, or negative acknowledgement (NACK) information for the first HARQ process.

[0151] In some embodiments, the terms “acknowledgement”, “positive”, “acknowledgment”, “positive”, “acknowledgement”, “positive response”, “positive acknowledgement”, and the like can be replaced by each other.

[0152] In some embodiments, the terms “negative acknowledgement”, “negative response”, “negative acknowledgement”, and the like can be replaced by each other.

[0153] In some embodiments, the first HARQ process is used to transmit a first uplink transmission, and the first uplink transmission is one of a plurality of uplink transmissions.

[0154] In some embodiments, the network device 102 can send the first information to the terminal 101 after receiving the at least one uplink transmission.

[0155] In some embodiments, the network device 102 can send the first information through a physical downlink control channel (PDCCH).

[0156] In some embodiments, the terminal 101 receives the first information sent by the network device 102.

[0157] Step S2104, determining that the target timer is a first timer of the first HARQ process.

[0158] In some embodiments, the first timer of the first HARQ process is a configured grant timer of the first HARQ process.

[0159] In some embodiments, the configured grant timer can be a timer associated with a configured grant (CG) of a non-dynamic transmission of a physical uplink shared channel (PUSCH). The configured grant timer can be used to determine whether the configured grant is within a valid time, or to trigger reconfiguration or release after timeout.

[0160] In some embodiments, the first information scheduling the first HARQ process can be a PDCCH uplink (UL) grant scheduling information. For example, a dynamic scheduling (e.g., a new transmission scheduling) addressed by a cell radio network temporary identifier (C-RNTI) or a retransmission scheduling addressed by a configured scheduling (CS) RNTI, and the like, which are not limited in the present disclosure.

[0161] In some embodiments, when the first information received by the terminal 101 is for a new transmission scheduling, it can be determined that the network device 102 has successfully received the uplink transmission, so that the terminal 101 can determine that the configured resource associated with the first HARQ process (for transmitting at least one of the plurality of uplink transmissions) needs to be updated, so that the terminal 101 can determine that the timer to be processed at this time is the configured grant timer of the first HARQ process.

[0162] In some embodiments, when the first information received by the terminal 101 is for a new transmission scheduling, it can be determined that the network device 102 has failed to successfully receive the uplink transmission sent by the process, so that the configured resource associated with the first HARQ process needs to be updated, and thus the terminal 101 can determine that the timer to be processed at this time is the configured grant timer of the first HARQ process.

[0163] Step S2105, stop the first timer of the first HARQ process.

[0164] In some embodiments, the network device 102 can stop the first timer (such as the configured grant timer) of the first HARQ process after sending the first information to the terminal 101.

[0165] In some embodiments, the terminal 101 can stop the configured grant timer of the first HARQ process after receiving the first information for scheduling the first HARQ process.

[0166] Step S2106, the terminal 101 does not obtain the MAC PDU to be transmitted scheduled by the first information, and clears the buffer of the first HARQ process.

[0167] In some embodiments, when the terminal 101 does not obtain the MAC PDU, it indicates that the terminal 101 currently has no new uplink transmission to be sent to the network device 102, so that the buffer of the scheduled first HARQ process can be cleared.

[0168] In some embodiments, the order of the steps S2104, S2105 and S2106 can be adjusted as needed. For example, S2104 and S2106 can be executed in parallel, and then S2105 is executed; or S2106 is executed first, and then S2104 and S2105 are executed, and so on, which are not limited in the present disclosure.

[0169] Step S2107: stopping the first timer of the second HARQ process.

[0170] In some embodiments, the terminal 101 and the network device 102 can stop the first timer (such as the configured grant timer) of the second HARQ process when it is determined that the last transmission through the second HARQ process is one of the multiple uplink transmissions.

[0171] In some embodiments, the second HARQ process is used to transmit other uplink transmissions of the multiple uplink transmissions.

[0172] In some embodiments, the network device 102 can determine the identity of the other HARQ process used by other uplink transmissions carrying the same data, such as the second HARQ process, after receiving at least one uplink transmission. Thus, the configured grant timer of the second HARQ process can be stopped at the same time after the first information for scheduling the first HARQ process is sent to the terminal 101.

[0173] In some embodiments, the terminal 101 can stop the configured grant timer of the second HARQ process for transmitting the same uplink transmission at the same time after receiving the first information for scheduling the first HARQ process.

[0174] In some embodiments, the network device 102 and the terminal 101 can first determine whether the last transmission of the HARQ process used by other uplink transmissions is one of the multiple uplink transmissions before stopping the configured grant timer of the HARQ process, and then stop the corresponding configured grant timer if so.

[0175] In some embodiments, the network device 102 and the terminal 101 can only stop the configured grant timer when the timer is in a running state.

[0176] In some embodiments, since the network device 102 has received at least one of the multiple uplink transmissions, the terminal 101 can also clear the buffer of the second HARQ process if the multiple uplink transmissions are transmitted through multiple HARQ processes.

[0177] In some embodiments, the order of steps S2106 and S2107 described above can be adjusted as needed. For example, S2106 and S2107 can be executed in parallel; or S2107 is executed first, and then S2106 is executed, and the like, which are not limited by the present disclosure.

[0178] The communication method related to the embodiments of the present disclosure can include at least one of steps S2101 to S2107. For example, step S2101 can be implemented as an independent embodiment, step S2103 can be implemented as an independent embodiment, steps S2101+S2102+S2104+S2105 can be implemented as an independent embodiment, and the like, but are not limited thereto.

[0179] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0180] FIG. 2B is an interaction diagram of a transmission method according to an embodiment of the present disclosure. As shown in FIG. 2B, the embodiments of the present disclosure relate to a transmission method, and the method includes:

[0181] Step S2201, determining at least one HARQ process from a HARQ process pool.

[0182] Step S2202, the terminal 101 sends a plurality of uplink transmissions through the at least one HARQ process.

[0183] Step S2203, the network device 102 sends first information to the terminal 101.

[0184] The specific implementation of steps S2201-S2203 described above can refer to the related parts of steps S2101-S2103 and optional implementation shown in FIG. 2A of the present disclosure, which will not be repeated here.

[0185] Step S2204, determining that the target timer is the second timer of the first HARQ process.

[0186] In some embodiments, the first information is response information of the first HARQ process, and then the target timer can be determined as the second timer.

[0187] In some embodiments, the second timer of the first HARQ process can be a DRX HARQ round trip time timer and / or a DRX HARQ retransmission timer of the first HARQ process.

[0188] In some embodiments, the timing value of the DRX HARQ round trip time timer can be used to reflect the minimum time interval that the terminal expects to receive the corresponding downlink transmission after sending the uplink transmission. Generally, the terminal starts timing after sending the uplink transmission, and stops timing until the terminal receives the expected downlink data.

[0189] In some embodiments, the DRX HARQ retransmission timer is mainly used to control the retransmission process of data transmission. It can be used to control the maximum time interval that the terminal waits for the uplink retransmission grant.

[0190] In step S2205, the second timer of the first HARQ process is stopped.

[0191] In some embodiments, the second timer of the first HARQ process can be the DRX HARQ round trip time timer and / or the DRX HARQ retransmission timer of the first HARQ process.

[0192] In some embodiments, the response information of the first HARQ process can be the acknowledgment (ACK) information for the first HARQ process, which is used to indicate that the network device 102 has successfully received the uplink transmission transmitted through the first HARQ process.

[0193] In some embodiments, the response information of the first HARQ process can be the uplink new transmission scheduling for the first HARQ process.

[0194] In the discontinuous reception (DRX) mechanism, when the terminal 101 receives the control signaling of the initial transmission or retransmission of HARQ, it will start the hybrid automatic repeat reQuest round-trip time timer (HARQ RTT Timer) of the HARQ process. It is used to determine the minimum time interval for waiting for retransmission in the HARQ process. If no retransmission data is received within this time interval, the terminal will take appropriate measures, such as starting a retransmission timer or entering a sleep state.

[0195] In some embodiments, if the terminal 101 receives the response information for the first HARQ process, the round trip time of the HARQ process can be determined based on the timing value of the DRX HARQ round trip time timer of the first HARQ process, so that the DRX HARQ round trip time timer of the first HARQ process can be stopped.

[0196] In some embodiments, after the network device 102 sends the response information for the first HARQ process to the terminal 101, the network device 102 can determine the round trip time of the HARQ process based on the value of the DRX HARQ round trip time timer of the first HARQ process, and can stop the DRX HARQ round trip time timer of the first HARQ process.

[0197] In some embodiments, the terminal and the network device can determine the round trip time in various ways. For example, the terminal and the network device can determine the round trip time based on the value of the DRX HARQ round trip time timer of the first HARQ process. In this case, the round trip time can be determined based on the value of the DRX HARQ round trip time timer of the first HARQ process. For another example, the round trip time can be determined based on the response information of the first HARQ process, or the response information of the HARQ process is used to determine the round trip time.

[0198] In some embodiments, the terminal and the network device can determine whether to stop the DRX HARQ round trip time timer of the first HARQ process in various ways. For example, the terminal and the network device can determine to stop the DRX HARQ round trip time timer of the first HARQ process based on the round trip time. In this case, the method of determining the round trip time can refer to the above, and will not be repeated here.

[0199] In the DRX mechanism, when the terminal 101 does not successfully receive data (downlink (DL) data) during the DRX period, the terminal 101 starts a DRX HARQ retransmission timer. During the running of the DRX HARQ retransmission timer, the terminal 101 listens to the control channel (such as PDCCH) to wait for the retransmission data of the corresponding HARQ process. If the first information is successfully received before the timer expires, the DRX HARQ retransmission timer can be stopped.

[0200] In some embodiments, after the network device 102 sends the first information to the terminal 101, the network device 102 can stop the DRX HARQ retransmission timer.

[0201] In some embodiments, the terminal and the network device can determine the retransmission time in various ways. For example, the terminal and the network device can determine the retransmission time based on the value of the DRX HARQ retransmission timer of the first HARQ process. In this case, the retransmission time can be determined based on the value of the DRX HARQ retransmission timer of the first HARQ process. For another example, the retransmission time can be determined based on the response information of the first HARQ process, or the response information of the HARQ process is used to determine the retransmission time.

[0202] In some embodiments, the terminal and the network device can determine whether to stop the DRX HARQ retransmission timer of the first HARQ process in various ways. For example, the terminal and the network device can determine to stop the DRX HARQ retransmission timer of the first HARQ process based on the retransmission time. The method of determining the retransmission time can refer to the above, and will not be described here.

[0203] In step S2206, the second timer of the second HARQ process is stopped.

[0204] In some embodiments, the second timer of the second HARQ process can be the DRX HARQ round trip time timer and / or the DRX HARQ retransmission timer of the second HARQ process.

[0205] In some embodiments, the terminal 101 and the network device 102 can stop the DRX HARQ round trip time timer and / or the DRX HARQ retransmission timer of the second HARQ process when it is determined that the last transmission through the second HARQ process is one of the multiple uplink transmissions.

[0206] The specific implementation of step S2206 can refer to the related part of the above-mentioned step S2106 and the optional implementation of the step S2106 shown in FIG. 2A of the present disclosure, which will not be described here.

[0207] The communication method related to the embodiments of the present disclosure can include at least one of steps S2201-S2206. For example, step S2201 can be implemented as an independent embodiment, step S2203 can be implemented as an independent embodiment, steps S2201+S2202+S2204+S2205 can be implemented as an independent embodiment, and the like, but is not limited thereto.

[0208] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0295] Optionally, the uplink packet and the packet obtained by copying the uplink packet are collectively referred to as a copied packet.

[0303] Optionally, the UL Grant described above is a dynamic scheduling (new transmission scheduling) addressed by C-RNTI or a retransmission scheduling addressed by CS-RNTI.

[0304] Optionally, if the HARQ Process has one-to-one mapping relationship with the time domain location of the configured resource, the corresponding HARQ Process can be different when the terminal selects different configured resources to send multiple duplicated packets.

[0305] Optionally, the terminal stops the configuredGrantTimer of the HARQ Process used for sending other duplicated packets before judging whether the last transmission of the HARQ Process is the transmission of the duplicated packet, and if so, stops the corresponding configuredGrantTimer.

[0306] Optionally, the terminal stops the configuredGrantTimer only when the timer is in running state.

[0307] Optionally, if the terminal fails to obtain the MAC PDU to be transmitted for one UL Grant, and the HARQ Process corresponding to the UL Grant is one of the HARQ Processes used for multiple duplicated packet transmission, the terminal clears the buffer of the HARQ Process corresponding to the UL Grant.

[0314] receiving a PDCCH indicating ACK for the HARQ Process;

[0315] Optionally, the terminal stops the DRX HARQ RTT Timer and / or DRX retransmission Timer corresponding to the HARQ Process used for the duplicated packet transmission, before stopping the DRX HARQ RTT Timer and / or DRX retransmission Timer corresponding to the other HARQ Process used for the other duplicated packet transmission.
