Abstract
Description
Uplink transmission method and apparatus Technical Field
[0001] This disclosure relates to the field of communication technology, and in particular to an uplink transmission method and apparatus. Background Technology
[0002] Contention resolution diversity slotted ALOHA (CRDSA) is a technique that reduces the probability of uplink collisions and improves uplink capacity by reducing contention in a channel. The terminal replicates the uplink transmission to generate multiple copies, which are then transmitted at different times. When the network successfully receives any one of these copies, it performs interference cancellation at other receiving locations based on the received uplink transmission, thus resolving other uplink transmissions that collided with that packet at other receiving locations.
[0003] Summary of the Invention
[0004] This disclosure presents an uplink transmission method and apparatus.
[0005] The first aspect of this disclosure provides an uplink transmission method, which is executed by a terminal, and the method includes:
[0006] A first configuration resource for sending a first uplink transmission is determined, which overlaps in the time domain with a second configuration resource for sending a second uplink transmission, wherein the first uplink transmission is one of a plurality of first copy packets of first content;
[0007] The first uplink transmission is sent first, or the second uplink transmission is sent first.
[0008] A second aspect of this disclosure provides a terminal, the terminal comprising:
[0009] The processing module is configured to determine a first configuration resource for sending a first uplink transmission that overlaps with a second configuration resource for sending a second uplink transmission in the time domain, wherein the first uplink transmission is one of a plurality of first copy packets of first content;
[0010] The transceiver module is used to prioritize sending the first uplink transmission or prioritize sending the second uplink transmission.
[0011] The solution proposed in this disclosure involves a terminal prioritizing one of the two uplink transmissions when it determines that there is temporal overlap between two configuration resources used to send two uplink transmissions. This ensures that when the terminal sends multiple uplink transmissions carrying the same content using configuration resources, if a collision occurs with other uplink transmissions, the higher-priority uplink transmission is prioritized, thus improving the reliability of uplink transmissions.

[0019] This disclosure presents an uplink transmission method and apparatus.
[0020] In a first aspect, embodiments of this disclosure propose an uplink transmission method, the method comprising: determining a first configuration resource for sending a first uplink transmission, which overlaps in the time domain with a second configuration resource for sending a second uplink transmission, wherein the first uplink transmission is one of a plurality of first copy packets of first content; and prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission.
[0021] In the above embodiments, when the terminal determines that there is temporal overlap between the two configuration resources used to send two uplink transmissions respectively, it prioritizes sending one of the two uplink transmissions. Therefore, when the terminal uses configuration resources to send multiple uplink transmissions carrying the same content, if a collision occurs with other uplink transmissions, it prioritizes sending the uplink transmission with the higher priority, thus improving the reliability of uplink transmissions.
[0022] In conjunction with some embodiments of the first aspect, in some embodiments, the step of preferentially sending the first uplink transmission or preferentially sending the second uplink transmission includes: preferentially using the first configuration resources to send the first uplink transmission, wherein the priority of the logical channel of the first uplink transmission is higher than the priority of the logical channel of the second uplink transmission; or, preferentially using the second configuration resources to send the second uplink transmission, wherein the priority of the logical channel of the first uplink transmission is lower than the priority of the logical channel of the second uplink transmission.
[0023] In the above embodiments, when the configuration resources corresponding to the first uplink transmission and the second uplink transmission overlap in the time domain, the uplink transmission with the higher priority of the corresponding logical channel is sent first, thereby ensuring that the uplink transmission sent through the higher priority logical channel has higher reliability and a higher probability of being received.
[0024] In conjunction with some embodiments of the first aspect, in some embodiments, the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, and the step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0025] Either the first uplink transmission or the second uplink transmission is sent preferentially.
[0026] Alternatively, the second uplink transmission may be sent using the second configuration resource first, wherein the second uplink transmission is an SR; or, the second uplink transmission may be a non-copy packet of the second content, and the first uplink transmission may be any packet other than the first of the plurality of first copy packets.
[0027] In the above embodiments, when the configuration resources corresponding to two uplink transmissions overlap in the time domain, the terminal can decide which one to send first, or, if an uplink transmission consists of multiple replicated packets (excluding the first one), to send the non-replicated packets first. This increases the probability that both conflicting uplink transmissions are received, thus improving the reliability of the communication system.
[0028] In conjunction with some embodiments of the first aspect, in some embodiments, the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, and the step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0029] The first uplink transmission is the first of the plurality of first copy packets, and the second uplink transmission is the other packets in the plurality of second copies of the second content except for the first one. The first uplink transmission is sent using the first configuration resource first.
[0030] Alternatively, the first uplink transmission may be any packet other than the first of the plurality of first replica packets, and the second uplink transmission may be the first of the plurality of second replica packets, with the second configuration resource being used preferentially to send the second uplink transmission.
[0031] In the above embodiments, when the configuration resources corresponding to the two uplink transmissions overlap in the time domain, and both uplink transmissions are one of multiple replicated packets, the terminal can prioritize sending the first replicated packet. This increases the probability that the first replicated packet among multiple replicated packets will be received, providing conditions for network devices to perform accurate channel estimation and interference cancellation.
[0032] In conjunction with some embodiments of the first aspect, in some embodiments, the second uplink transmission is a Physical Uplink Shared Channel (PUSCH) scheduled by a random access response or by a Temporary Cell Radio Network Temporary Identifier (TC-RNTI), or the second uplink transmission is a non-replicated packet of the payload of the first random access message MsgA, or the second uplink transmission is a PUSCH scheduled by a Temporary Cell Radio Network Temporary Identifier (TC-RNTI).
[0033] The step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0034] The second uplink transmission is sent preferentially using the second configured resource.
[0035] In the above embodiments, when the configuration resources corresponding to the two uplink transmissions overlap in the time domain, and the second uplink transmission is scheduled by RAR, TC-RNTI, or C-RNTI, or is a non-replicated packet of the MsgA payload, the second uplink transmission is sent first. This maximizes the reliable execution of important services for effective communication by the terminal and improves the reliability of the communication system.
[0036] In conjunction with some embodiments of the first aspect, in some embodiments, the second uplink transmission is one of a plurality of second copy packets of the second content, the second content being the payload of the first random access message MsgA;
[0037] The step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0038] The first uplink transmission is sent using the first configured resource first, wherein the first uplink transmission is the first of the plurality of first replications, and the second uplink transmission is the other packets in the plurality of second replication packets except the first one;
[0039] Alternatively, the second uplink transmission may be sent using the second configuration resource first, wherein the first uplink transmission is one of the packets other than the first among the plurality of first copies.
[0040] In the above embodiments, when the configuration resources corresponding to the two uplink transmissions overlap in the time domain, and the second uplink transmission is one of multiple second replicated packets carrying the MsgA payload, the priority of transmission is determined based on whether the second uplink transmission and the first uplink transmission are the first among their respective replicated packets. This maximizes the reception probability of the first packet among the replicated packets while ensuring the reception probability of other replicated packets carrying the MsgA payload, thus providing conditions for improving the terminal's RA probability.
[0041] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:
[0042] When the terminal prioritizes sending the first uplink transmission, the transmission of the second uplink transmission is delayed or canceled; or...
[0043] [Amended according to Rule 26, 13.08.2024] When the terminal prioritizes sending the second uplink transmission, the sending of the first uplink transmission is delayed or canceled.
[0044] In the above embodiments, when the configuration resources corresponding to the two uplink transmissions overlap in the time domain, the uplink transmission with higher priority is sent first, and the uplink transmission with lower priority is not sent or is delayed in being sent. This improves the flexibility of processing the uplink transmission with lower priority while ensuring the probability of the uplink transmission with higher priority being reliably received, thereby improving the performance of the communication system.
[0045] In conjunction with some embodiments of the first aspect, in some embodiments, delaying the transmission of the second uplink transmission or delaying the transmission of the first uplink transmission includes:
[0046] Use the third configuration resource to send either the second uplink transmission or the first uplink transmission.
[0047] In the above embodiments, when the configuration resources corresponding to the two uplink transmissions overlap in the time domain, the new configuration resource is used to delay the transmission of one of the uplink transmissions. This avoids collision interference from multiple first copy packets while ensuring that each uplink transmission can be sent, thus improving the reliability of the communication system.
[0048] In conjunction with some embodiments of the first aspect, in some embodiments, delaying the transmission of the second uplink transmission or delaying the transmission of the first uplink transmission includes:
[0049] The network device is delayed for a first time period before sending either the second uplink transmission or the first uplink transmission. The first time period is configured by the network device or agreed upon by the protocol.
[0050] In the above embodiments, when the configuration resources corresponding to the two uplink transmissions overlap in the time domain, the terminal can delay sending one of the uplink transmissions based on the first time period agreed upon by the network device configuration or protocol. This ensures that the terminal and the network device have a consistent understanding of the delay duration, and provides a condition for improving the reception probability of the delayed uplink transmission.
[0051] Secondly, embodiments of this disclosure provide an uplink transmission method, which is executed by a communication system, the method comprising:
[0052] The terminal determines a first configuration resource for sending a first uplink transmission that overlaps with a second configuration resource for sending a second uplink transmission in the time domain, wherein the first uplink transmission is one of a plurality of first copy packets of first content;
[0053] The terminal prioritizes sending the first uplink transmission or the second uplink transmission.
[0054] Thirdly, this disclosure provides a terminal, which includes a transceiver module and a processing module; wherein the transceiver module is used to perform the transceiver operations in the first aspect and the embodiments described in the first aspect; and the processing module is used to perform the determination operations in the first aspect and the embodiments described in the first aspect.

[0084] As shown in Figure 1A, the communication system 100 includes a terminal 101 and a network device 102.

The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.
[0090] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Protocol Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).
[0091] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.
[0092] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A.

[0094] In the field of communication technology, Contention Resolution Diversity Slotted ALOHA (CRDSA) is a technique that reduces the probability of uplink collisions and improves uplink capacity by reducing contention in a channel. The terminal replicates the uplink transmission to generate multiple first-copy packets, and then sends these multiple first-copy packets at different times. The network successfully receives any one of these uplink transmissions, thus reducing the probability of collision failures.
[0095] In some embodiments, because terminals sending at least two identical uplink transmissions increases the probability of collisions, interference cancellation techniques are needed. The process is illustrated below with reference to Figure 1B. Figure 1B is a schematic diagram of uplink transmissions received by a network device. For example, a terminal sends two uplink transmissions, PK3. One PK3 transmission does not collide and can be correctly parsed by the network device. The other PK3 transmission collides with an uplink transmission PK2 sent by another terminal. The network device can then use the correctly parsed PK3 to perform interference cancellation on the other PK3 transmission, allowing it to correctly parse the uplink transmission PK2 sent by the other terminal. The network device can then use the parsed PK2 to perform interference cancellation on the other PK2 transmission, parsing PK1, and so on, until all parseable uplink transmissions are parsed, such as PK4, PK5, and PK6 in the figure.
[0096] For multiple uplink transmissions using configured grant (CG) resources, they may collide with other uplink transmissions in the time domain. These other uplink transmissions may also be multi-replica packet transmissions, scheduling request (SR) transmissions, dynamically scheduled transmissions, random access response (RAR) transmissions, or temporary identifiers from temporary cell radio networks.
[0097] Transmissions scheduled by the Temporary Cell Radio Network Temporary Identifier (TC-RNTI) or the payload of the first randomly accessed message (message A, MsgA) can be used to differentiate the priority of multi-copy packet transmissions from other uplink transmissions.
[0098] The uplink transmission method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.
[0099] Figure 2A is a flowchart illustrating an uplink transmission method according to an embodiment of the present disclosure. As shown in Figure 2A, the uplink transmission method according to this embodiment is executed by terminal 101, and the method includes:
[0100] Step S2101: Determine the multiple first copy packets to be sent.
[0101] In some embodiments, terminal 101 can make one or more copies of the first content to be sent to obtain multiple first copy packets.
[0102] In some embodiments, terms such as "uplink transmission," "uplink send," "uplink copy packet," "copy packet," "uplink data packet," "uplink packet," and "uplink information" can all refer to uplink transmitted data and / or control signaling, and therefore they can be used interchangeably in some cases.
[0103] In some embodiments, the first content carried in multiple first replicated packets is the same. That is, the effective information carried in multiple first replicated packets is the same. For example, the payload in multiple first replicated packets is the same; or, the Media Access Control (MAC) Protocol Data Unit (PDU) in multiple first replicated packets is the same; or the MAC Service Data Unit (SDU) in multiple first replicated packets is the same.
[0104] In some embodiments, the uplink transmission can be a MACPDU or a MACSDU.
[0105] In some embodiments, the terminal may be a non-terrestrial network (NTN) terminal or a terrestrial network (TN) terminal.
[0106] Step S2102: Determine the configuration resources for sending multiple first copy packets.
[0107] In some embodiments, multiple first copy packets may be transmitted using multiple configured resources respectively.
[0108] In some embodiments, the configuration resource may be a ConfiguredGrant (CG) resource.
[0109] For example, the configuration resource can be a CG resource configured based on Radio Resource Control (RRC). Alternatively, it can be a CG resource activated based on Downlink Control Information (DCI), meaning the configuration resource can be a ConfiguredGrantType 1 resource or a ConfiguredGrantType 2 resource. Alternatively, it can be a preconfigured uplink resource (PUR) or other types of preconfigured resources.
[0110] In some embodiments, the ConfiguredGrant resource is a resource used in an inactive or connected state.
[0111] In some embodiments, the CG resources used in the inactive state may be, for example, CG resources used for small packet transmission, or CG resources configured for the connected state.
[0112] In some embodiments, the terminal can randomly select multiple CG resources from the resource pool configured in the network device.
[0113] In some embodiments, at least one of the time-domain, frequency-domain, and / or code-domain resources among the multiple CG resources selected by terminal 101 may be discontinuous.
[0114] In some embodiments, the code domain resource can be a demodulation reference signal (DMRS).
[0115] For example, multiple CG resources can be multiple CG resources that are not contiguous in the time domain, or they can be resources corresponding to different DMRS, etc. This disclosure does not limit them.
[0116] In some embodiments, if the time domain positions of the multiple CG resources selected by terminal 101 are the same, but the frequency domain and / or code domain resources are different, then terminal 101 is required to send multiple first copy packets to the network device at the same time. In order to ensure that each uplink transmission can be reliably sent, terminal 101 needs to provide a large transmission power. In order to avoid this situation as much as possible, this disclosure allows terminal 101 to select CG resources corresponding to different time domain timings when selecting CG resources for sending multiple first copy packets.
[0117] In some embodiments, terminal 101 may select the HARQ process corresponding to the CG resource from the HARQ process pool after selecting the CG resource for sending multiple first copy packets.
[0118] In some embodiments, when selecting CG resources, terminal 101 can also select CG resources corresponding to the same HARQ process but at different time domains. That is, terminal 101 ultimately uses the same HARQ process to send multiple uplink transmissions carrying the same content to network device 102.
[0119] In some embodiments, if the time domain positions of the multiple CG resources selected by terminal 101 are different, and there is a one-to-one mapping relationship between the HARQ process and the time domain position of the configuration resource, then when terminal 101 selects different configuration resources to send multiple copy packets, the corresponding HARQ processes may be the same or different.
[0120] In some embodiments, the terminal may select different HARQ processes from the HARQ process pool to transmit multiple first copy packets respectively.
[0121] In some embodiments, the number of copies (or quantity, such as 2 uplink transmissions, 3 uplink transmissions, etc.) of the multiple first replica packets can be agreed upon by the system or configured by the network device. For example, the number of copies of the multiple first replica packets can be indicated in the CG configuration or in the CG's scheduling DCI.
[0122] In some embodiments, configuration resources can be shared by multiple terminals, or the network device can configure configuration resources for each terminal separately for sending multiple first copy packets.
[0123] Step S2103: The first configuration resource used to send the first uplink transmission overlaps with the second configuration resource used to send the second uplink transmission in the time domain. It is determined whether the priority of the logical channel of the first uplink transmission is higher than the priority of the logical channel of the second uplink transmission.
[0124] In some embodiments, the first uplink transmission is one of a plurality of first replica packets. For example, the first uplink transmission is the first of a plurality of first replica packets, or the first uplink transmission is any packet other than the first of a plurality of first replica packets.
[0125] In some embodiments, the content carried by the second uplink transmission is different from that carried by the first uplink transmission.
[0126] In some embodiments, the second uplink transmission may be one of multiple second copy packets, or it may be an SR transmission, etc., and this disclosure does not limit it in this way.
[0127] In some embodiments, the first configuration resource and the second configuration resource overlap in the time domain. This means that the time domain location occupied by the first configuration resource is the same as or partially the same as the time domain location occupied by the second configuration resource.
[0128] In some embodiments, the control logic channel has a higher priority than the data logic channel.
[0129] In some embodiments, if the priority of the logical channel occupied by any first uplink transmission is higher than the priority of the logical channel occupied by the second uplink transmission, then the priority of any first uplink transmission is higher than that of the second uplink transmission.
[0130] In some embodiments, if the priority of the logical channel occupied by the second uplink transmission is higher than the priority of the logical channel occupied by any first uplink transmission, then the priority of the second uplink transmission is higher than that of any first uplink transmission.
[0131] In some embodiments, the logical channels occupied by any first uplink transmission and the second uplink transmission have the same priority, and the terminal 101 can decide which uplink transmission to send first.
[0132] In step S2104, the logical channel of the first uplink transmission has a higher priority than the logical channel of the second uplink transmission. The first uplink transmission is sent using the first configuration resource first, and the transmission of the second uplink transmission is delayed or canceled.
[0133] In step S2105, the priority of the logical channel of the first uplink transmission is lower than that of the logical channel of the second uplink transmission. The second configuration resource is used first to send the second uplink transmission, and the first uplink transmission is delayed or canceled.
[0134] In some embodiments, terminal 101 may use the configuration resources corresponding to an uplink transmission with a higher logical channel priority to send the uplink transmission.
[0135] In this embodiment, if the time-domain resources corresponding to two uplink transmissions overlap, the terminal 101 needs to send both uplink transmissions simultaneously. However, since the uplink transmission power of the terminal 101 cannot be increased indefinitely, the terminal 101 may need to reduce the transmission power of at least one uplink transmission, thus affecting the probability of reliable reception of that uplink transmission. In this embodiment, when the time-domain resources corresponding to two uplink transmissions overlap, the priority of the logical channels corresponding to the two uplink transmissions is determined, and the uplink transmission with the higher priority of the corresponding logical channel is sent first. This ensures the probability of reliable reception of the uplink transmission with the higher priority of the corresponding logical channel, improving the reliability of the uplink transmission.
[0136] In this embodiment of the disclosure, the terminal determines the uplink transmission with the higher priority among the occupied logical channels as the higher priority uplink transmission, thereby ensuring the reliability of the uplink transmission sent through the higher priority logical channel and the probability of it being reliably received.
[0137] In some embodiments, after sending an uplink transmission with a higher logical channel priority, the terminal can cancel sending another uplink transmission with a lower logical channel priority, thereby reducing the uplink traffic while ensuring the reliability of the uplink transmission with the higher logical channel priority.
[0138] In some embodiments, terminal 101 may also re-determine a configuration resource, such as a third configuration resource, for an uplink transmission that was not sent first, and send the unsent uplink transmission based on the re-determined third configuration resource.
[0139] In some embodiments, after sending a prioritized uplink transmission, terminal 101 may delay for a period of time before using third configuration resources to send the remaining uplink transmission.
[0140] In some embodiments, the third configuration resource does not conflict with other configuration resources already determined for uplink transmission. For example, it does not conflict in the time domain.
[0141] In some embodiments, when the logical channels of two uplink transmissions are the same, the terminal can cancel or delay sending another uplink transmission after sending one uplink transmission, thereby minimizing the probability of collisions between uplink transmissions and providing conditions for network devices to perform accurate interference cancellation.
[0142] In some embodiments, when an uplink transmission that is delayed is one of multiple replicated packets, the terminal 101 reselects a third configuration resource for it, and the transmission interval between the configuration resources used by the other replicated packets associated with it is less than a certain interval threshold.
[0143] In some embodiments, terminal 101 may determine the interval threshold based on the configuration of network device 102, or, according to a protocol agreement, determine the interval threshold.
[0144] In some embodiments, the interval between the configuration resources used by multiple replicated packets carrying the same content is less than the interval threshold. This can prevent the accumulated timing advance (TA) deviation between multiple replicated packets from exceeding the processing capacity limit of the network device, thus providing conditions and guarantees for the network device to accurately eliminate interference in uplink transmission.
[0145] In step S2106, the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission. Either the first uplink transmission or the second uplink transmission is sent first, and the other transmission is canceled.
[0146] In some embodiments, when the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, the terminal can determine which uplink transmission to send first. For example, the terminal can send the first uplink transmission first, or send the second uplink transmission first.
[0147] In some embodiments, when the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, the terminal can also determine which uplink transmission to send first based on the content carried by the second uplink transmission.
[0148] In some embodiments, the second uplink transmission is SR. If the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, the terminal can prioritize sending the second uplink transmission. This maximizes the reliable execution of the terminal's scheduling services and improves the terminal's communication performance.
[0149] In some embodiments, when the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, if the second uplink transmission is a non-copy packet of the second content, and the first uplink transmission is a packet other than the first copy packet among a plurality of first copy packets, then the terminal may also send the second uplink transmission with priority. This ensures that the content of each uplink transmission can be reliably sent as much as possible.
[0150] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2105. For example, step S2101 may be implemented as a standalone embodiment, step S2101+S2102+S2103 may be implemented as a standalone embodiment, step S2101+S2102+S2103+S2104 may be implemented as a standalone embodiment, and so on, but it is not limited thereto.
[0151] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.
[0152] Figure 2B is a flowchart illustrating an uplink transmission method according to an embodiment of the present disclosure. As shown in Figure 2B, the uplink transmission method according to this embodiment is executed by terminal 101, and the method includes:
[0153] Step S2201: Determine the multiple first copy packets to be sent.
[0154] Step S2202: Determine the configuration resources for sending multiple first copy packets.
[0155] The specific implementation of the above steps S2201-S2202 can be referred to steps S2101-S2102 and the relevant parts of the optional implementation shown in Figure 2A of this disclosure, and will not be repeated here.
[0156] Step S2203: The first configuration resource used to send the first uplink transmission overlaps with the second configuration resource used to send the second uplink transmission in the time domain, and the two have the same logical channel priority. The first uplink transmission is the first of a plurality of first copy packets, and the second uplink transmission is the other packets in a plurality of second copies of the second content except the first one. The first configuration resource is used first to send the first uplink transmission, and the second uplink transmission is delayed or canceled.
[0157] In some embodiments, terms such as "the first of a plurality of first copy packets", "the first copy packet of a plurality of first copy packets to be sent", "the earliest copy packet of a plurality of first copy packets to be sent", and "the earliest copy packet of a plurality of first copy packets to occupy a time domain position" can be used interchangeably.
[0158] In some embodiments, terms such as "other packets besides the first", "other packets besides the first copied packet sent", and "other packets besides the earliest copied packet sent" can be used interchangeably.
[0159] For example, multiple first copy packets, arranged from front to back in the time domain, are named A1, A2, and A3, and multiple second copy packets, arranged from front to back in the time domain, are named B1, B2, and B3. If the first configuration resource used to send A1 overlaps with the second configuration resource used to send B2 (or B3) in the time domain, the terminal can prioritize using the first configuration resource to send A1 and delay or cancel sending B2 (or B3).
[0160] Step S2204: The first configuration resource used to send the first uplink transmission overlaps with the second configuration resource used to send the second uplink transmission in the time domain, and the two have the same logical channel priority. The first uplink transmission is any packet other than the first one among multiple first replica packets, and the second uplink transmission is the first one among multiple second replica packets. The second configuration resource is used first to send the second uplink transmission, and the first uplink transmission is delayed or canceled.
[0161] For example, multiple first copy packets, arranged from front to back in the time domain, are named A1, A2, and A3, and multiple second copy packets, arranged from front to back in the time domain, are named B1, B2, and B3. If the first configuration resource used to send A2 (or A3) overlaps with the second configuration resource used to send B1 in the time domain, then the terminal can prioritize using the second configuration resource to send B1 and delay or cancel sending A2 (or A3).
[0162] The specific implementation of steps S2203-S2204 can be referred to steps S2103-S2105 and the relevant parts of the optional implementation shown in Figure 2A of this disclosure, and will not be repeated here.
[0163] The communication method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2204. For example, step S2201 may be implemented as a standalone embodiment, step S2202 may be implemented as a standalone embodiment, step S2203 may be implemented as a standalone embodiment, step S2201+S2202+S2203 may be implemented as a standalone embodiment, step S2201+S2202+S2204 may be implemented as a standalone embodiment, etc., but not limited thereto.
[0164] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.
[0165] Figure 2C is a flowchart illustrating an uplink transmission method according to an embodiment of the present disclosure. As shown in Figure 2C, the uplink transmission method involved in this embodiment is executed by a terminal, and the method includes:
[0166] Step S2301: Determine the multiple first copy packets to be sent.
[0167] Step S2302: Determine the configuration resources for sending multiple first copy packets.
[0168] The specific implementation of the above steps S2301-S2302 can be referred to steps S2101-S2102 and the relevant parts of the optional implementation shown in Figure 2A of this disclosure, and will not be repeated here.
[0169] Step S2303: The first configuration resource used to send the first uplink transmission overlaps with the second configuration resource used to send the second uplink transmission in the time domain. The second uplink transmission is a specified type of uplink transmission, and the second configuration resource is used preferentially to send the second uplink transmission.
[0170] In some embodiments, a specified uplink transmission may be a Physical Uplink Shared Channel (PUSCH) scheduled by RAR or TC-RNTI.
[0171] In some embodiments, a specified uplink transmission may be a non-copy packet of the payload of the first random access message MsgA.
[0172] In some embodiments, terms such as "non-copy packet" and "non-multiple uplink transmission" can be used interchangeably.
[0173] In some embodiments, a specified uplink transmission may also be a PUSCH scheduled by C-RNTI.
[0174] For example, if multiple first-replicated packets are numbered A1, A2, and A3 according to their time-domain positions from front to back, and the first uplink transmission is any one of A1, A2, or A3, and the second uplink transmission is a PUSCH scheduled by RAR, TC-RNTI, or C-RNTI, or a non-replicated packet of the MsgA payload, then the terminal can prioritize using the second configuration resource to send the second uplink transmission. Alternatively, it can cancel sending the first uplink transmission or use the third configuration resource to delay sending the first uplink transmission.
[0175] In this embodiment of the present disclosure, the specific implementation of delaying the transmission of the first uplink transmission can be referred to the relevant description in steps S2104-S2106 of the embodiment shown in FIG2A above, which will not be repeated here.
[0176] In this embodiment of the disclosure, when any one of the multiple first copy packets overlaps with a specified uplink transmission in the time domain, the specified uplink transmission is sent first. This maximizes the reliable execution of important services for effective communication by the terminal and improves the reliability of the communication system.
[0177] The communication method involved in the embodiments of this disclosure may include at least one of steps S2301 to S2303. For example, step S2301 may be implemented as a standalone embodiment, step S2302 may be implemented as a standalone embodiment, step S2302+S2303, etc., but is not limited thereto.
[0178] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.
[0179] Figure 2D is a flowchart illustrating an uplink transmission method according to an embodiment of the present disclosure. As shown in Figure 2D, the uplink transmission method according to this embodiment is executed by terminal 101, and the method includes:
[0180] Step S2401: Determine the multiple first copy packets to be sent.
[0181] Step S2402: Determine the configuration resources for sending multiple first copy packets.
[0182] The specific implementation of the above steps S2401-S2402 can be referred to steps S2101-S2102 and the relevant parts of the optional implementation shown in Figure 2A of this disclosure, and will not be repeated here.
[0183] Step S2403: The first configuration resource for sending the first uplink transmission overlaps with the second configuration resource for sending the second uplink transmission in the time domain. The second uplink transmission is one of a plurality of second replica packets of the MsgA payload. Determine whether the first uplink transmission is the first of the plurality of first replica packets, and / or whether the second uplink transmission is the first of the plurality of second replica packets.
[0184] In step S2404, the first uplink transmission is the first of a plurality of first replicas, and the second uplink transmission is the other packets in a plurality of second replica packets excluding the first one. The first uplink transmission is sent using the first configuration resource first, and the second uplink transmission is delayed or canceled.
[0185] Step S2405: Prioritize using the second configuration resource to send the second uplink transmission, and delay or cancel sending the first uplink transmission.
[0186] For example, multiple first-copy packets, arranged from front to back in the time domain, are named A1, A2, and A3. Multiple second-copy packets, arranged from front to back in the time domain, are named B1, B2, and B3. The content of all the second-copy packets is the payload of MsgA. If the first configuration resource used to send A1 overlaps in the time domain with the second configuration resource used to send B2 (or B3), then the terminal can prioritize using the first configuration resource to send A1 and delay or cancel sending B2 (or B3).
[0187] If the first configuration resource used to send A2 (or A3) overlaps with the second configuration resource used to send B1 (or B2, or B3) in the time domain, then the terminal can preferentially use the second configuration resource to send B1 (or B2, or B3) and delay or cancel sending A2 (or A3).
[0188] In this embodiment of the disclosure, the specific implementation of delaying the transmission of the first uplink transmission or the second uplink transmission can be referred to the relevant description in steps S2104-S2106 of the embodiment shown in FIG2A above, which will not be repeated here.
[0189] In this embodiment of the disclosure, when the configuration resources in the multiple replica packets used to send two different contents overlap in the time domain, and the content of the second uplink transmission is the payload of MsgA, the first of the multiple replica packets can be sent first, or the payload of MsgA can be sent first. This maximizes the reception probability of the first packet among the multiple replica packets while ensuring the reception probability of other replica packets carrying the payload of MsgA, thus providing conditions for improving the RA probability of the terminal.
[0190] The communication method involved in the embodiments of this disclosure may include at least one of steps S2401 to S2405. For example, step S2401 may be implemented as a standalone embodiment, step S2402 may be implemented as a standalone embodiment, steps S2403+S2404 may be implemented as standalone embodiments, steps S2303+S2305 may be implemented as standalone embodiments, and so on, but is not limited thereto.
[0191] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.
[0192] Figure 2E is a flowchart illustrating an uplink transmission method according to an embodiment of the present disclosure. As shown in Figure 2E, this embodiment of the present disclosure relates to an uplink transmission method, which is executed by terminal 101, and includes:
[0193] Step S2501: Determine a first configuration resource for sending the first uplink transmission that overlaps with a second configuration resource for sending the second uplink transmission in the time domain.
[0194] In some embodiments, the first uplink transmission is one of a plurality of first copy packets of the first content.
[0195] In some embodiments, the terminal can obtain multiple first uplink transmissions by copying the uplink transmissions.
[0196] Step S2502: Prioritize sending the first uplink transmission or prioritize sending the second uplink transmission.
[0197] In some embodiments, prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0198] The first uplink transmission is sent using the first configured resource first, wherein the logical channel of the first uplink transmission has a higher priority than the logical channel of the second uplink transmission.
[0199] Alternatively, the second uplink transmission may be transmitted using the second configuration resource first, wherein the logical channel of the first uplink transmission has a lower priority than the logical channel of the second uplink transmission.
[0200] In some embodiments, the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, and the step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0201] Either the first uplink transmission or the second uplink transmission is sent preferentially.
[0202] Alternatively, the second uplink transmission may be sent using the second configuration resource first, wherein the second uplink transmission is an SR; or, the second uplink transmission may be a non-copy packet of the second content, and the first uplink transmission may be any packet other than the first of the plurality of first copy packets.
[0203] In some embodiments, the priority of the logical channel of the first uplink transmission is the same as the priority of the logical channel of the second uplink transmission, and the step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0204] The first uplink transmission is the first of the plurality of first copy packets, and the second uplink transmission is the other packets in the plurality of second copies of the second content except for the first one. The first uplink transmission is sent using the first configuration resource first.
[0205] Alternatively, the first uplink transmission may be any packet other than the first of the plurality of first replica packets, and the second uplink transmission may be the first of the plurality of second replica packets, with the second configuration resource being used preferentially to send the second uplink transmission.
[0206] In some embodiments, the second uplink transmission is a Physical Uplink Shared Channel (PUSCH) scheduled by a Random Access Response (RAR) or by a Temporary Cell Radio Network Temporary Identifier (TC-RNTI), or the second uplink transmission is a non-replicated packet of the payload of the first Random Access Message (MsgA), or the second uplink transmission is a PUSCH scheduled by a Temporary Cell Radio Network Temporary Identifier (C-RNTI).
[0207] The step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0208] The second uplink transmission is sent preferentially using the second configured resource.
[0209] In some embodiments, the second uplink transmission is one of a plurality of second copy packets of the second content, the second content being the payload of the first random access message MsgA;
[0210] The step of prioritizing the transmission of the first uplink transmission or prioritizing the transmission of the second uplink transmission includes:
[0211] The first uplink transmission is sent using the first configured resource first, wherein the first uplink transmission is the first of the plurality of first replications, and the second uplink transmission is the other packets in the plurality of second replication packets except the first one;
[0212] Alternatively, the second uplink transmission may be sent using the second configuration resource first, wherein the first uplink transmission is one of the packets other than the first among the plurality of first copies.
[0213] In some embodiments, the method further includes:
[0214] When the terminal prioritizes sending the first uplink transmission, the transmission of the second uplink transmission is delayed or canceled; or...
[0215] [Amended according to Rule 26, 13.08.2024] When the terminal prioritizes sending the second uplink transmission, the sending of the first uplink transmission is delayed or canceled.
[0216] In some embodiments, delaying the transmission of the second uplink transmission or delaying the transmission of the first uplink transmission includes:
[0217] Use the third configuration resource to send either the second uplink transmission or the first uplink transmission.
[0218] In some embodiments, delaying the transmission of the second uplink transmission or delaying the transmission of the first uplink transmission includes:
[0219] The network device is delayed for a first time period before sending either the second uplink transmission or the first uplink transmission. The first time period is configured by the network device or agreed upon by the protocol.
[0220] Steps S2501 to S2502 and their optional implementations can be found in the relevant parts of Figures 2A-2D, and will not be repeated here.
[0221] The uplink transmission method provided in this disclosure will be further described below with reference to the following embodiments.
[0222] When a terminal needs to send an uplink packet, it makes one or more copies of the uplink packet to obtain multiple copies (multiple uplink transmissions), and uses configuration resources to send the multiple copies.
[0223] Optionally, the uplink packet and the packet obtained by copying the uplink packet are collectively referred to as the copied packet.
[0224] Optionally, the configuration resource can be a Configured Grant (such as a Configured Grant based on RRC configuration or a Configured Grant based on DCI activation, i.e., Configured Grant Type 1 and Configured Grant Type 2), or a preconfigured uplink Resource (PUR), or other types of preconfigured resources.
[0225] Optionally, the Configured Grant resource is a resource used in either the inactive or connected state. Inactive CG resources include those used for small packet transmissions, while connected CG resources are configured for the connected state.
[0226] Optionally, the uplink packet is a MAC PDU or a MAC SDU.
[0227] Optionally, the number of copies of the package is determined by the system or configured by the network, such as indicated in the CG configuration or in the CG's scheduling DCI.
[0228] Optionally, the configuration resources can be shared by multiple UEs.
[0229] Optionally, the terminal is an NTN terminal or a TN terminal, and the network is an NTN network or a TN network.
[0230] Alternatively, for one or more of the following cases:
[0231] There is temporal overlap between the transmission of the first copied packet in a multi-copy packet and the transmission of the first copied packet in another multi-copy packet;
[0232] There is temporal overlap between a copy packet that is not the first to be sent in a multi-copy packet and a copy packet that is not the first to be sent in another multi-copy packet.
[0233] Process in one or more of the following ways:
[0234] If the logical channels corresponding to these two replicated packets have different priorities, the replicated packet with the higher priority corresponding to the logical channel will be sent first.
[0235] If the logical channels corresponding to these two replicated packets have the same priority, the terminal determines which replicated packet to send.
[0236] Optionally, if the first copied packet sent in a multi-copy packet overlaps in the time domain with a copied packet that is not the first sent in another multi-copy packet, it shall be handled in one or more of the following ways:
[0237] If the logical channels corresponding to these two replicated packets have different priorities, the replicated packet with the higher priority corresponding to the logical channel will be sent first.
[0238] If the logical channels corresponding to these two replicated packets have the same priority, the first replicated packet to be sent will be sent first.
[0239] Optionally, for low-priority copy packets, the terminal can cancel or delay sending.
[0240] Optionally, for delayed transmission, the terminal may reselect a configuration resource for transmission within a certain period. The reselected configuration resource should not conflict with other configuration resources already designated for multi-replication packet transmission. For example, it should not conflict in the time domain. The configuration resource reselected by the terminal should satisfy the condition that the interval between it and the first transmitted replication packet in the multi-replication packet is less than an interval threshold, which can be determined based on a configuration value or a conventional value.
[0241] Optionally, if any of the multiple replication packets overlaps with the SR in the time domain, it shall be handled in one or more of the following ways:
[0242] If the priority of the logical channel corresponding to the copy packet is different from the priority of the logical channel corresponding to the SR, the packet with the higher priority of the corresponding logical channel shall be sent first.
[0243] If the priority of the logical channel corresponding to the copy packet is the same as the priority of the logical channel corresponding to the SR, the SR is sent first.
[0244] Optionally, if any of the multiple copy packets overlaps in the time domain with a PUSCH scheduled by RAR or TC-RNTI, or overlaps with a MsgA payload that is not transmitted using multiple copy packets, the latter shall be sent first.
[0245] Optionally, if any of the multiple copy packets overlaps with the payload of MsgA transmitted using multiple copy packets, it shall be handled in one or more of the following ways:
[0246] If the time-domain resources occupied by the first copied packet sent in a multi-copy packet overlap with those occupied by a non-first copied packet in the MsgA payload transmitted in the multi-copy packet, the first copied packet sent in the multi-copy packet will be sent first.

In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
