[0025] The section headings used in this document are for ease of understanding only and do not limit the scope of the embodiments to the section in which they are described. In addition, although the embodiments are described with reference to 5G examples, the disclosed technology can be applied to wireless systems using protocols other than 5G or 3GPP protocols.

[0026] The fifth generation (5G) mobile communication system supports a variety of application scenarios, including enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine type communication (mMTC). As wireless communication technology is increasingly used in many applications, 5G mobile communication focuses on researching and supporting features such as enhanced mobile broadband, ultra-high reliability, ultra-low latency transmission, and large-scale connections.

[0027] In an uplink service transmission scenario, to support a terminal's higher-priority transmission service, the network node can schedule the transmission service using downlink control information (DCI). However, a resource scheduling conflict may occur when time-frequency resources have already been scheduled for transmission of a certain uplink service before the same time-frequency resources are scheduled for a certain terminal. To avoid conflicts between two different terminals, the lower-priority service is canceled or carried forward. The information is reused in the time-frequency resources of the higher-priority service. At the same time, to ensure the high reliability and low-latency transmission characteristics of high-priority uplink transmission services from other terminals, the network node prioritizes the resources used for the transmission services, and the target resources are now allocated to the higher-priority service. The transmission service is occupied by the terminal, and the terminal further cancels the transmission of the higher-priority service based on the uplink cancellation information (ULCI) carried by the DCI to ensure uplink transmission services for other terminals. If the lower-priority service previously canceled by the terminal does not conflict with the high-priority service of other terminals, the cancellation of the service is redundant and unnecessary, resulting in a decrease in the overall performance of the terminal.

[0028] The performance degradation caused by the additional cancellation of uplink transmission services by the terminal can be offset by restoring the lower priority services previously canceled by the terminal. Since it takes a certain amount of time to restore the canceled services, the terminal cannot restore the canceled uplink transmission services in all cases.

[0029] The disclosed techniques can be implemented in some embodiments to ensure that a terminal can resume a cancelled uplink transmission service. The disclosed techniques can also be implemented in some embodiments to provide a method and system for handling conflicts in transmission services to avoid additional cancellations caused by conflicts between inter-terminal and intra-terminal services.

[0030] Methods and systems implemented based on some embodiments of the disclosed technology can improve resource usage efficiency and avoid unnecessary additional cancellations by flexibly canceling scheduled uplink transmissions and efficiently adjusting the execution order of transmission cancellations.

[0031] Example Embodiments

[0032] Example 1

[0033] The disclosed technology may be implemented in some embodiments to provide methods and systems for a user equipment (UE) to cancel uplink transmissions, as described below.

[0034] Figure 1 Depicted are examples of time-frequency domain resources in which uplink transmissions are scheduled according to a control information message including downlink control information (DCI) based on some example embodiments of the disclosed technology.

[0035] In some embodiments of the disclosed technology, a base station sends downlink control information (DCI) to a UE, and the UE that receives the DCI schedules uplink transmission or cancels uplink transmission according to the information carried by the DCI. Figure 1 As shown. The base station sends DCI1, DCI2 and DCI3. DCI1 schedules the first uplink transmission, DCI2 schedules the second uplink transmission, and the DCI3 message carries transmission cancellation information such as ULCI (uplink cancellation information). ULCI indicates that the third uplink transmission of other terminals is on the uplink reference resource (for example, Figure 1 (As shown in the Reference Uplink Resource (RUR)). When a UE transmits a first uplink transmission and a second uplink transmission, there are two cases in which the priorities of the two types of transmission services are determined. Specifically, the priority of the first uplink transmission is higher than the priority of the second uplink transmission, or the first uplink transmission and the second uplink transmission have the same priority. The first uplink transmission and the second uplink transmission completely or partially overlap in the time domain, and the first uplink transmission completely or partially overlaps with the time-frequency resources that need to be occupied in the RUR.

[0036] According to the service conflict cancellation rules in the agreed intra-UE priority sorting / multiplexing mechanism, when the first uplink transmission priority is higher than the second uplink transmission priority, the UE will completely cancel the second uplink transmission. When the first uplink transmission priority is the same as the second uplink transmission priority, and when the first uplink transmission is a physical uplink shared channel (PUSCH) and the second uplink transmission is a physical uplink control channel (PUCCH), the UE will cancel the entire second uplink transmission, and the information carried by the second uplink transmission is multiplexed on the first uplink transmission. According to the service conflict cancellation rules in the agreed inter-UE priority sorting / multiplexing mechanism, the UE needs to cancel the first uplink transmission. The UE receives DCI1, DCI2, and DCI3 within a short time frame (e.g., one time slot), and the method for canceling uplink transmission includes at least one of the following:

[0037] Method 1:

[0038] In some embodiments of the disclosed technology, a UE may perform a temporal analysis on control information messages including DCI and / or ULCI to implement transmission cancellation using one of multiple cancellation modes based on the temporal analysis. In some implementations, the temporal analysis is performed based on a timeline associated with the control information messages including the DCI and / or ULCI. In one example, a new timeline is defined in the protocol. In another example, a timeline defined in the current protocol may be used for the purpose of temporal analysis based on embodiments of the disclosed technology. In some implementations, a first timeline and a second timeline are configured for such temporal analysis. Assume that the first timeline is n symbols, and the second timeline is m symbols. The UE determines the order in which uplink transmissions are canceled by checking whether the times t0 and t1 from the target DCI to the target uplink transmission meet predetermined timeline conditions. Based on the target DCI and the target uplink transmission, the starting and ending times of t0 and t1 may be determined. In some implementations, if t0 is not less than n, then t0 is considered to meet the predetermined timeline condition, and if t1 is not less than m, then t1 is considered to meet the predetermined timeline condition.

[0039] When both t0 and t1 meet the predetermined timeline conditions, the UE first performs inter-UE cancellation, i.e., the UE first cancels the uplink transmission that fully or partially overlaps with the time-frequency resources occupied by the uplink transmission of another UE and indicated by the ULCI. When at least one of t0 and t1 does not meet the predetermined timeline conditions, the UE performs cancellation according to the order of arrival of the DCI message (e.g., on a first-come, first-served basis) or performs intra-UE cancellation according to existing protocols.

[0040] Furthermore, the method for the UE to determine n and m includes at least one of the following:

[0041] (1) The values ​​of n and m (e.g., T pro,2 , the time when the UE decodes the DCI and prepares to send or cancel uplink transmission) is predefined in the protocol;

[0042] (2) A set of candidate values ​​for n and m is predefined in the protocol, and the UE determines the specific values ​​based on its own capabilities;

[0043] (3) Fixed value k (e.g., T pro,2 , the time it takes for the UE to decode the DCI and prepare for transmission) is predefined in the protocol, and a set of candidate values ​​of d1 and d2 (the time it takes for the UE to cancel UL transmission or prepare a channel) (e.g., the time it takes for the UE to cancel UL transmission or prepare a channel for transmission) is predefined in the protocol, and the UE determines a value from the candidate values ​​according to its own capability, and determines the specific values ​​of n and m after adding the k value; and

[0044] (4) The candidate values ​​of n and m are predefined in the protocol and configured to the UE through RRC signaling.

[0045] In one example, the predefined values ​​of n and m in the protocol may be the time it takes for a UE to decode a DCI and prepare for or cancel an uplink transmission. In one example, the fixed value k may be the time it takes for a UE to decode a DCI and prepare for transmission.

[0046] Method 2:

[0047] In one example, a new timeline is defined in the protocol. In another example, the timeline defined in the current protocol can be used for the purpose of time analysis based on an embodiment of the disclosed technology. In some implementations, a first timeline is set for time analysis purposes. As an example and not a limitation, assume that the first timeline is n symbols. The UE determines the cancellation order of the uplink transmission by checking whether the time t0 from the target DCI to the target uplink transmission meets the predetermined timeline condition. The target DCI and the target uplink transmission can determine the starting time point and the ending time point of t0, wherein when t0 is less than n, t0 meets the predetermined timeline condition.

[0048] Specifically, when t0 meets the predetermined timeline condition, the UE first performs inter-UE cancellation, that is, the UE first cancels the uplink transmission that completely or partially overlaps with the time-frequency resources occupied by the uplink transmission of another UE and indicated by the ULCI. When t0 does not meet the predetermined timeline condition, the UE performs cancellation according to the order of arrival of the DCI message (for example, on a first-come, first-served basis) or performs intra-UE cancellation according to existing protocols.

[0049] Furthermore, the method for the UE to determine the value of n includes at least one of the following:

[0050] (1) The value of n (e.g., T pro,2 , the time when the UE decodes the DCI and prepares to send or cancel uplink transmission) is predefined in the protocol;

[0051] (2) A set of candidate values ​​for n is predefined in the protocol, and the UE determines the specific value based on its own capabilities;

[0052] (3) Fixed value k (e.g., T pro,2 , the time it takes for the UE to decode the DCI and prepare for transmission) is predefined in the protocol, and a set of candidate values ​​of d1 (which is the time it takes for the UE to cancel UL transmission or prepare a channel) (e.g., the time it takes for the UE to cancel UL transmission or prepare a channel for transmission) is predefined in the protocol, and the UE determines a value from the candidate values ​​according to its own capability, and determines a specific value of n after adding the value of k; and

[0053] (4) The candidate value of n predefined by the protocol is configured to the UE through RRC signaling.

[0054] In one example, the predefined value of n in the protocol may be the time it takes for the UE to decode the DCI and prepare or cancel an uplink transmission. In one example, the fixed value k may be the time it takes for the UE to decode the DCI and prepare for transmission.

[0055] Method 3:

[0056] In one example, a new timeline is defined in the protocol. In another example, the timeline defined in the current protocol can be used for the purpose of time analysis based on an embodiment of the disclosed technology. In some implementations, a second timeline is set for time analysis purposes. As an example and not a limitation, assume that the second timeline is m symbols. The UE determines the cancellation order of the uplink transmission by checking whether the time t1 from the target DCI to the target uplink transmission meets the predetermined timeline condition. The target DCI and the target uplink transmission can determine the starting time point and the ending time point of t1, where when t0 is less than m, t1 meets the predetermined timeline condition.

[0057] Specifically, when t1 satisfies a predetermined timeline condition, the UE first performs inter-UE cancellation, i.e., the UE first cancels uplink transmissions that fully or partially overlap with time-frequency resources occupied by another UE's uplink transmission and indicated by the ULCI. When t1 does not meet the predetermined timeline condition, the UE performs cancellation according to the order in which the DCI messages arrive (e.g., on a first-come, first-served basis) or performs intra-UE cancellation according to existing protocols.

[0058] Furthermore, the method for the UE to determine the value of m includes at least one of the following:

[0059] (1) The value of m (for example, T pro,2 , the time when the UE decodes the DCI and prepares to send or cancel uplink transmission) is predefined in the protocol;

[0060] (2) A set of candidate values ​​for m is predefined in the protocol, and the UE determines the specific value based on its own capabilities;

[0061] (3) Fixed value k (e.g., T pro,2 , the time it takes for the UE to decode the DCI and prepare for transmission) is predefined in the protocol, and a set of candidate values ​​of d2 (which is the time it takes for the UE to cancel UL transmission or prepare a channel) (e.g., the time it takes for the UE to cancel UL transmission or prepare a channel for transmission) is predefined in the protocol, and the UE determines a value from the candidate values ​​according to its own capability, and determines a specific value of m after adding the k value; and

[0062] (4) The candidate values ​​of m predefined by the protocol are configured to the UE through RRC signaling.

[0063] In one example, the predefined value of m in the protocol may be the time it takes for the UE to decode the DCI and prepare or cancel an uplink transmission. In one example, the fixed value k may be the time it takes for the UE to decode the DCI and prepare for transmission.

[0064] When checking whether t0 meets the timeline condition, the UE needs to determine the actual time domain length of t0. The UE determines the time domain length of t0 by simple calculation based on the starting time point and the ending time point. The method for a specific UE to determine the starting time point of t0 includes at least one of the following:

[0065] (1) The starting time point of t0 is the last symbol of the DCI message carrying ULCI; and

[0066] (2) The starting time point of t0 is the last symbol of the last target DCI to which the UE can respond. Specifically, the target DCI is the last arriving DCI in a group of DCIs. The group of DCIs includes all DCI messages that schedule the first uplink transmission and the second uplink transmission and / or carry ULCI.

[0067] The method for determining the end time point of t0 by the UE includes at least one of the following:

[0068] (1) The end time point of t0 is the first symbol of the earliest uplink transmission or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other;

[0069] (2) the end time point of t0 is the first symbol of the earliest uplink transmission or the first symbol of the part to be cancelled in a group of uplink transmissions that at least partially overlap with each other and completely or partially overlap with the RUR;

[0070] (3) the end time point of t0 is the first symbol of the earliest high-priority uplink transmission or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other;

[0071] (4) the end time point of t0 is the first symbol of the earliest high-priority uplink transmission or the first symbol of the part to be canceled in a group of uplink transmissions that at least partially overlap with each other and fully or partially overlap with the RUR;

[0072] (5) The end time point of t0 is the first symbol of the earliest high-priority PUSCH in a group of uplink transmissions that at least partially overlap with each other or the first symbol of the part to be cancelled;

[0073] (6) the end time point of t0 is the first symbol of the earliest high priority PUSCH or the first symbol of the portion to be cancelled in a group of uplink transmissions that at least partially overlap with each other and fully or partially overlap with the RUR; and

[0074] (7) The end time point of t0 is the first symbol of the earliest uplink transmission or the first symbol of the part to be canceled in a group of uplink transmissions that at least partially overlap with each other and completely or partially overlap with the time-frequency resources indicated by the ULCI.

[0075] In one implementation, the group of uplink transmissions may include all uplink transmissions from the UE that fully or partially overlap with other uplink transmissions in the time domain. In another implementation, the group of overlapping uplink transmissions includes all uplink transmissions that fully or partially overlap with other uplink transmissions, as well as time-frequency resources occupied by uplink transmissions of another UE and indicated by the ULCI, which are considered high-priority uplink transmissions.

[0076] like Figure 1 As shown, the starting time point of t0 is the last symbol of the DCI3 message carrying ULCI, and the ending time point of t0 is the first symbol of the earliest uplink transmission.

[0077] When checking whether t1 meets the timeline condition, the UE needs to determine the actual time domain length of t1. The UE determines the time domain length of t1 by simple calculation based on the starting time point and the ending time point. The method for a specific UE to determine the starting time point t1 includes at least one of the following:

[0078] (1) The starting time point of t1 is the last symbol of the DCI message carrying ULCI; and

[0079] (2) The starting time point of t1 is the last symbol of the last target DCI to which the UE can respond. Specifically, the target DCI is the last arriving DCI in a group of DCIs. The group of DCIs includes all DCI messages that schedule the first uplink transmission and the second uplink transmission and / or carry ULCI.

[0080] The method for determining the end point of t1 by the UE includes at least one of the following:

[0081] (1) In a group of uplink transmissions that at least partially overlap with each other, an uplink transmission that completely or partially overlaps with resources occupied by an uplink transmission of another UE and indicated by the ULCI is recorded as A. The end time point of t1 is the first symbol of the earliest uplink transmission that completely or partially overlaps with uplink transmission A and does not completely or partially overlap with resources occupied by an uplink transmission of another UE and indicated by the ULCI, or the first symbol of the portion to be canceled.

[0082] (2) Among a group of uplink transmissions that at least partially overlap with each other, among uplink transmissions that completely or partially overlap with the RUR, an uplink transmission that completely or partially overlaps with resources occupied by uplink transmission of another UE and indicated by the ULCI is recorded as A. The end time point of t1 is the first symbol of the earliest uplink transmission that completely or partially overlaps with uplink transmission A and does not completely or partially overlap with resources occupied by uplink transmission of another UE and indicated by the ULCI, or the first symbol of the portion to be canceled.

[0083] (3) The end time point of t1 is the first symbol of the uplink transmission that needs to be saved or restored or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other.

[0084] The set of uplink transmissions may include all uplink transmissions transmitted by the UE that fully or partially overlap with other uplink transmissions in the time domain.

[0085] like Figure 1 As shown, the starting time point of t1 is the last symbol of the DCI3 message carrying ULCI, and the ending time point of t1 is the first symbol of the second uplink transmission, which is the first symbol that arrives first and completely or partially overlaps with the first uplink transmission, and does not completely or partially overlap with the resources occupied by the uplink transmission of another UE and indicated by the ULCI.

[0086] Example 2

[0087] The disclosed technology may be implemented in some embodiments to provide methods and systems for user equipment (UE) to cancel uplink transmissions, as described below.

[0088] Figure 2 Depicted are examples of time-frequency domain resources in which uplink transmissions are scheduled according to a control information message including downlink control information (DCI) based on some example embodiments of the disclosed technology.

[0089] In some embodiments of the disclosed technology, a base station sends downlink control information (DCI) to a UE, and the UE that receives the DCI schedules uplink transmission or cancels uplink transmission according to the information carried by the DCI. Figure 2 As shown. The base station sends DCI1, DCI2, and DCI3. DCI1 schedules the first uplink transmission, DCI2 schedules the second uplink transmission, and the DCI3 message carries transmission cancellation information such as ULCI. ULCI indicates the time-frequency resources that need to be occupied by the third uplink transmission of other terminals (for example, Figure 2 (As shown in the Reference Uplink Resource (RUR)). When a UE transmits a first uplink transmission and a second uplink transmission, there are two cases in which the priorities of the two types of transmission services are determined. Specifically, the first uplink transmission has a higher priority than the second uplink transmission, or the first uplink transmission and the second uplink transmission have the same priority. The first uplink transmission and the second uplink transmission completely or partially overlap in the time domain, and the first uplink transmission completely or partially overlaps with the time-frequency resources required to be occupied in the RUR.

[0090] According to the service conflict cancellation rules in the agreed intra-UE priority sorting / multiplexing mechanism, when the first uplink transmission priority is higher than the second uplink transmission priority, the UE will completely cancel the second uplink transmission. When the first uplink transmission priority is the same as the second uplink transmission priority, and when the first uplink transmission is a physical uplink shared channel (PUSCH) and the second uplink transmission is a physical uplink control channel (PUCCH), the UE will cancel the second entire uplink transmission, and the information carried by the second uplink transmission is multiplexed on the first uplink transmission. According to the service conflict cancellation rules in the agreed inter-UE priority sorting / multiplexing mechanism, the UE needs to cancel the first uplink transmission. The UE receives DCI1, DCI2, and DCI3 within a short time frame (e.g., one time slot), and the method for canceling uplink transmission includes at least one of the following:

[0091] Method 1:

[0092] In some embodiments of the disclosed technology, a UE may perform time analysis on a control information message including DCI and / or ULCI to implement transmission cancellation using one of multiple cancellation modes based on the time analysis. In some implementations, the time analysis is performed based on a timeline and / or reference time point inferred from the control information message including the DCI and / or ULCI. In one example, a new timeline is defined in the protocol. In another example, a timeline defined in the current protocol may be used for the purpose of time analysis based on an embodiment of the disclosed technology. In some implementations, a first timeline and a second timeline are set for such time analysis purposes, assuming that the first timeline is n symbols and the second timeline is m symbols. The UE infers a reference time point for the latest DCI message carrying the ULCI using the first time endpoint, the second time endpoint, and the timeline value. If the DCI message carrying the ULCI arrives before the reference time point, the UE first performs an inter-UE cancellation, i.e., the UE cancels the uplink transmission that fully or partially overlaps with the time-frequency resources occupied by another UE's uplink transmission and indicated by the ULCI. If the DCI message carrying the ULCI does not arrive before the reference time point, the UE performs cancellation according to the order of arrival of the DCI messages (for example, on a first-come, first-served basis) or performs intra-UE cancellation according to existing protocols. If two different reference time points are derived from the first time endpoint and the second time endpoint, the time endpoint that is located before the other time endpoint in the time domain is selected as the reference time point.

[0093] Furthermore, the method for the UE to determine the values ​​of n and m includes at least one of the following:

[0094] (1) The values ​​of n and m (e.g., T pro,2 , the time when the UE decodes the DCI and prepares to send or cancel uplink transmission) is predefined in the protocol;

[0095] (2) A set of candidate values ​​for n and m is predefined in the protocol, and the UE determines the specific values ​​based on its own capabilities;

[0096] (3) Fixed value k (e.g., T pro,2 , the time it takes for the UE to decode the DCI and prepare for transmission) is predefined in the protocol, and a set of candidate values ​​of d1 and d2 (i.e., the time it takes for the UE to cancel UL transmission or prepare a channel) (e.g., the time it takes for the UE to cancel UL transmission or prepare a channel for transmission) is predefined in the protocol, and the UE determines a value from the candidate values ​​according to its own capability, and specific values ​​of n and m are determined after adding the k value; and

[0097] (4) The candidate values ​​of n and m are predefined in the protocol and configured to the UE through RRC signaling.

[0098] In one example, the predefined values ​​of n and m in the protocol may be the time it takes for a UE to decode a DCI and prepare for or cancel an uplink transmission. In one example, the fixed value k may be the time it takes for a UE to decode a DCI and prepare for transmission.

[0099] Method 2:

[0100] In one example, a new timeline is defined in the protocol. In another example, the timeline defined in the current protocol can be used for the purpose of time analysis based on an embodiment of the disclosed technology. In some implementations, a first timeline is set for time analysis purposes, assuming that the first timeline is n symbols. The UE infers the reference time point for the latest DCI message carrying the ULCI by the first end time point and the timeline value. If the DCI message carrying the ULCI arrives before the reference time point, the UE first performs an inter-UE cancellation, that is, the UE cancels the uplink transmission that fully or partially overlaps with the time-frequency resources occupied by the uplink transmission of another UE and indicated by the ULCI. If the DCI message carrying the ULCI does not arrive before the reference time point, the UE performs cancellation in the order of arrival of the DCI messages (for example, on a first-come, first-served basis) or performs an intra-UE cancellation according to the existing protocol.

[0101] Furthermore, the method for the UE to determine the values ​​of n and m includes at least one of the following:

[0102] (1) The value of n (e.g., T pro,2 , the time when the UE decodes the DCI and prepares to send or cancel uplink transmission) is predefined in the protocol;

[0103] (2) A set of candidate values ​​for n is predefined in the protocol, and the UE determines the specific value based on its own capabilities;

[0104] (3) Fixed value k (e.g., T pro,2 , the time it takes for the UE to decode the DCI and prepare for transmission) is predefined in the protocol, and a set of candidate values ​​of d1 (i.e., the time it takes for the UE to cancel UL transmission or prepare a channel) (e.g., the time it takes for the UE to cancel UL transmission or prepare a channel for transmission) is predefined in the protocol, and the UE determines a value from the candidate values ​​according to its own capability, and a specific value of n is determined after adding the value of k; and

[0105] (4) The candidate values ​​of n are predefined in the protocol and configured to the UE through RRC signaling.

[0106] In one example, the predefined value of n in the protocol may be the time it takes for the UE to decode the DCI and prepare or cancel an uplink transmission. In one example, the fixed value k may be the time it takes for the UE to decode the DCI and prepare for transmission.

[0107] Method 3:

[0108] In one example, a new timeline is defined in the protocol. In another example, the timeline defined in the current protocol can be used for the purpose of time analysis based on an embodiment of the disclosed technology. In some implementations, a second timeline is set for time analysis purposes, assuming that the second timeline is m symbols. The UE infers the reference time point for the latest DCI message carrying the ULCI by the second end time point and the timeline value. If the DCI message carrying the ULCI arrives before the reference time point, the UE first performs an inter-UE cancellation, that is, the UE cancels the uplink transmission that completely or partially overlaps with the time-frequency resources occupied by the uplink transmission of another UE and indicated by the ULCI. If the DCI message carrying the ULCI does not arrive before the reference time point, the UE performs cancellation in the order of arrival of the DCI messages (for example, on a first-come, first-served basis) or performs an intra-UE cancellation according to the existing protocol.

[0109] Furthermore, the method for the UE to determine the values ​​of n and m includes at least one of the following:

[0110] (1) The value of m (e.g., T pro,2 , the time when the UE decodes the DCI and prepares to send or cancel uplink transmission) is predefined in the protocol;

[0111] (2) A set of candidate values ​​for m is predefined in the protocol, and the UE determines the specific value based on its own capabilities;

[0112] (3) Fixed value k (e.g., T pro,2 , the time it takes for the UE to decode the DCI and prepare for transmission) is predefined in the protocol, and a set of candidate values ​​of d2 (i.e., the time it takes for the UE to cancel UL transmission or prepare a channel) (e.g., the time it takes for the UE to cancel UL transmission or prepare a channel for transmission) is predefined in the protocol, and the UE determines a value from the candidate values ​​according to its own capability, and a specific value of m is determined after adding the k value; and

[0113] (4) The candidate values ​​of m are predefined in the protocol and configured to the UE through RRC signaling.

[0114] In one example, the predefined value of m in the protocol may be the time it takes for the UE to decode the DCI and prepare or cancel an uplink transmission. In one example, the fixed value k may be the time it takes for the UE to decode the DCI and prepare for transmission.

[0115] The method for the UE to determine the first time endpoint includes at least one of the following:

[0116] (1) The first end time point is the first symbol of the earliest uplink transmission or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other;

[0117] (2) the first end time point is the first symbol of the earliest uplink transmission or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other and completely or partially overlap with the RUR;

[0118] (3) the first end time point is the first symbol of the earliest high-priority uplink transmission or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other;

[0119] (4) the first end time point is the first symbol of the earliest high-priority uplink transmission or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other and completely or partially overlap with the RUR;

[0120] (5) The first end time point is the first symbol of the earliest high-priority PUSCH in a group of uplink transmissions that at least partially overlap with each other, or the first symbol of the portion to be canceled;

[0121] (6) the first end time point is the first symbol of the earliest high-priority PUSCH or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other and fully or partially overlap with the RUR; and

[0122] (7) The first end time point is the first symbol of the earliest uplink transmission or the first symbol of the part to be canceled in a group of uplink transmissions that at least partially overlap with each other and completely or partially overlap with the time-frequency resources indicated by the ULCI.

[0123] In one implementation, the overlapping uplink transmission group includes all uplink transmissions transmitted by the UE that fully or partially overlap with other uplink transmissions in the time domain. In another implementation, the overlapping uplink transmission group includes all uplink transmissions that fully or partially overlap with other uplink transmissions, as well as time-frequency resources occupied by uplink transmissions of another UE and indicated by the ULCI, which are considered high-priority uplink transmissions.

[0124] The method for the UE to determine the second time endpoint includes at least one of the following:

[0125] (1) In a group of uplink transmissions that at least partially overlap with each other, an uplink transmission that completely or partially overlaps with resources occupied by an uplink transmission of another UE and indicated by a ULCI is recorded as A. The second time endpoint is the first symbol of the earliest uplink transmission that completely or partially overlaps with uplink transmission A and does not completely or partially overlap with resources occupied by an uplink transmission of another UE and indicated by the ULCI, or the first symbol of the portion to be canceled.

[0126] (2) Among a group of uplink transmissions that at least partially overlap with each other, among uplink transmissions that completely or partially overlap with the RUR, an uplink transmission that completely or partially overlaps with resources occupied by an uplink transmission of another UE and indicated by the ULCI is recorded as A. The second time endpoint is the first symbol of the earliest uplink transmission that completely or partially overlaps with uplink transmission A and does not completely or partially overlap with resources occupied by an uplink transmission of another UE and indicated by the ULCI, or the first symbol of the portion to be canceled.

[0127] (3) The second time endpoint is the first symbol of the uplink transmission that needs to be saved or restored or the first symbol of the portion to be canceled in a group of uplink transmissions that at least partially overlap with each other.

[0128] The set of uplink transmissions may include all uplink transmissions transmitted by the UE that fully or partially overlap with other uplink transmissions in the time domain.

[0129] like Figure 2 As shown, the first end time point "b" is the first symbol of the first uplink transmission. The second end time point "c" is the first symbol of the second uplink transmission. The reference time point is postponed to "a" by the UE, and DCI3 arrives before point "a", so the UE first performs inter-UE cancellation.

[0130] Example 3

[0131] This embodiment describes a method for a UE to determine whether to resume a cancelled transmission service.

[0132] The implementation of the technical solution will be further described in detail below with reference to the accompanying drawings.

[0133] like Figure 1 As shown, the UE transmits a first uplink transmission and a second uplink transmission. There are two cases in which the priorities of the two types of transmission services are different. Specifically, the priority of the first uplink transmission is higher than the priority of the second uplink transmission, or the priority of the first uplink transmission is the same as the priority of the second uplink transmission.

[0134] The first uplink transmission is one of:

[0135] (1) The earliest uplink transmission in an overlapping uplink transmission group is the first uplink transmission;

[0136] (2) In an overlapping uplink transmission group, the earliest uplink transmission that fully or partially overlaps with the RUR is the first uplink transmission;

[0137] (3) The earliest uplink transmission with a high priority in the overlapping uplink transmission group is the first uplink transmission;

[0138] (4) In an overlapping uplink transmission group, the earliest uplink transmission with a high priority that fully or partially overlaps with the RUR is the first uplink transmission;

[0139] (5) The earliest PUSCH with high priority in the overlapping uplink transmission group is the first uplink transmission;

[0140] (6) In an overlapping uplink transmission group, the earliest PUSCH with high priority that fully or partially overlaps with the RUR is the first uplink transmission; and

[0141] (7) In an overlapping uplink transmission group, the earliest uplink transmission that completely or partially overlaps with the resources indicated by the ULCI is the first uplink transmission.

[0142] The second uplink transmission service is one of the following:

[0143] (1) In an overlapping uplink transmission group, an uplink transmission that completely or partially overlaps with resources indicated by the ULCI is recorded as A, and the earliest uplink transmission that completely or partially overlaps with uplink transmission A and does not completely or partially overlap with resources indicated by the ULCI is the second uplink transmission;

[0144] (2) In the overlapping uplink transmission group, among the uplink transmissions that completely or partially overlap with the RUR, the uplink transmission that completely or partially overlaps with the resources indicated by the ULCI is recorded as A, and the uplink transmission that completely or partially overlaps with the uplink transmission A. The earliest uplink transmission that does not completely or partially overlap with the resources indicated by the ULCI is the second uplink transmission; and

[0145] (3) In an overlapping uplink transmission group, the earliest uplink transmission that needs to be saved or restored is the second uplink transmission.

[0146] The overlapping uplink transmission group includes all uplink transmissions from the UE that fully or partially overlap with other uplink transmissions in the time domain. In another implementation, the overlapping uplink transmission group includes all uplink transmissions that fully or partially overlap with other uplink transmissions, as well as time-frequency resources occupied by uplink transmissions of another UE and indicated by the ULCI, which are considered high-priority uplink transmissions.

[0147] Furthermore, DCI1 schedules the first uplink transmission, and the DCI2 message carries ULCI, wherein the ULCI indicates the time-frequency resources that the third uplink transmission of the other terminal needs to occupy in the RUR. The first uplink transmission and the second uplink transmission completely or partially overlap in the time domain, and the first uplink transmission and the third uplink transmission completely or partially overlap in the time-frequency domain. According to the service conflict cancellation rule in the agreed-upon priority sorting / multiplexing mechanism within the UE, the UE cancels the second uplink transmission. The method for the UE to determine whether to resume the second uplink transmission channel includes at least one of the following:

[0148] Method 1:

[0149] The UE determines whether to resume the second uplink transmission channel according to the number of symbols in a time frame between the last symbol of the DCI message carrying the ULCI and the first symbol of the earliest uplink transmission.

[0150] If the UE resumes the second uplink transmission channel, the UE expects that the first symbol of the earliest channel carrying the first uplink transmission and the second uplink transmission satisfies the following timeline conditions:

[0151] (1) There are no fewer than n symbols between the last symbol of the DCI message carrying the ULCI and the first symbol of the earliest channel carrying the first uplink transmission channel, i.e., t0 is no less than n, and the first uplink transmission fully or partially overlaps with the third uplink transmission; and

[0152] (2) There are no fewer than m symbols between the last symbol of the DCI message carrying the ULCI and the first symbol of the earliest channel carrying the second uplink transmission channel, that is, t1 is not less than m, and the second uplink transmission completely or partially overlaps with the second uplink transmission and does not completely or partially overlap with the third uplink transmission.

[0153] Method 2:

[0154] The UE is determined based on the number of symbols in a time frame between the last symbol of the DCI carrying the ULCI and the first symbol of the earliest first uplink transmission.

[0155] The UE resumes the second uplink transmission channel. The UE expects that the first symbol of the earliest channel carrying the first uplink transmission satisfies the following timeline conditions:

[0156] There are no less than n symbols between the last symbol of the DCI message carrying the ULCI and the first symbol of the earliest channel carrying the first uplink transmission channel, that is, t0 is not less than n, and the uplink transmission fully or partially overlaps with the third uplink transmission.

[0157] Method 3:

[0158] The UE determines the value based on the number of symbols in a time frame between the last symbol of the DCI message carrying the ULCI and the first symbol of the earliest second uplink transmission channel.

[0159] The UE resumes the second uplink transmission channel. The UE expects that the first symbol of the earliest channel carrying the second uplink transmission satisfies the following timeline conditions:

[0160] There are no less than m symbols between the last symbol of the DCI message carrying the ULCI and the first symbol of the earliest channel carrying the second uplink transmission, that is, t1 is not less than m, and the uplink transmission fully or partially overlaps with the second uplink transmission and does not fully or partially overlap with the third uplink transmission.

[0161] Furthermore, the method of determining n and m includes at least one of the following:

[0162] (1) The value of m (e.g., T pro,2 , the time when the UE decodes the DCI and prepares to send or cancel uplink transmission) is predefined in the protocol;

[0163] (2) A set of candidate values ​​for m is predefined in the protocol, and the UE determines the specific value based on its own capabilities;

[0164] (3) Fixed value k (e.g., T pro,2 , the time it takes for the UE to decode the DCI and prepare for transmission) is predefined in the protocol, and a set of candidate values ​​of d2 (i.e., the time it takes for the UE to cancel UL transmission or prepare a channel) (e.g., the time it takes for the UE to cancel UL transmission or prepare a channel for transmission) is predefined in the protocol, and the UE determines a value from the candidate values ​​according to its own capability, and a specific value of m is determined after adding the k value; and

[0165] (4) Candidate values ​​of m or n are predefined in the protocol and configured to the UE through RRC signaling.

[0166] Example 4

[0167] This embodiment describes a method for a UE to determine whether to cancel all transmission services that conflict with resources indicated by a ULCI.

[0168] Figure 3 Depicted are examples of time-frequency domain resources in which uplink transmissions are scheduled according to a control information message including downlink control information (DCI) based on some example embodiments of the disclosed technology.

[0169] like Figure 3 As shown, the UE transmits a first uplink transmission and a second uplink transmission. There are two cases for the priority of the two types of transmission services. Specifically, the priority of the first uplink transmission is higher than the priority of the second uplink transmission, or the priority of the first uplink transmission is the same as the priority of the second uplink transmission. DCI1 schedules the first uplink transmission, the DCI2 message carries ULCI, and the ULCI indicates the time-frequency resources that the third uplink transmission of other terminals needs to occupy in the RUR. The first uplink transmission and the second uplink transmission completely or partially overlap in the time domain, and the first uplink transmission and the third uplink transmission completely or partially overlap in the time-frequency domain. A method for UE to cancel transmission of a first uplink transmission channel includes at least one of the following:

[0170] Method 1:

[0171] The UE's cancellation behavior is explicitly indicated by a single bit. An indication field is introduced, and the indication field contains an indication bit. When the indication bit value is 0, the UE cancels the first transmission channel that conflicts with and follows the third uplink transmission. When the indication bit value is 1, the UE cancels the entire first uplink transmission channel. The indication bit can be indicated by higher-layer signaling configuration or physical layer signaling.

[0172] Method 2:

[0173] The UE's cancellation behavior is explicitly indicated by a single bit. An indication field is introduced, and the indication field contains an indication bit. When the indication bit value is 1, the UE cancels the first transmission channel that conflicts with and follows the third uplink transmission. When the indication bit value is 0, the UE cancels the entire first uplink transmission channel. The indication bit can be indicated by higher-layer signaling configuration or physical layer signaling.

[0174] Method 3:

[0175] The UE determines the cancellation behavior based on the resource ratio of the first transmission occupied by the time-frequency resources indicated by the ULCI. In some embodiments of the disclosed technology, an indication threshold P is introduced, and the UE calculates the actual value p. Specifically, the number of resource blocks (RBs) occupied by the resources indicated by the ULCI in the first uplink is N When the weight value p>P, the UE cancels the entire first uplink transmission channel.When the weight value p≤P, the UE cancels the first transmission channel that conflicts with and follows the third uplink transmission.

[0176] The indication threshold P may be predefined by a protocol, or a candidate value of P predefined by a protocol may be configured by a higher layer signaling, or a candidate value configured by a higher layer signaling may be indicated by a physical layer signaling.

[0177] Method 4:

[0178] The UE determines the cancellation behavior based on the ratio of the time-frequency resources indicated by the ULCI to the resources of the first transmission multiplexed with the information carried by the second transmission. The indication threshold P is introduced, and the UE calculates the actual value p. Specifically, the ULCI indicates that the number of RBs of the time-frequency domain resources multiplexed on the first transmission with the resources occupied by the second transmission is The number of RBs of the time-frequency domain resources for multiplexing the information in the first transmission is When the weight value p>P, the UE cancels the entire first uplink transmission channel.When the weight value p≤P, the first transmission channel collides with and follows the third uplink transmission.

[0179] The indication threshold P may be predefined by the protocol, or the candidate value of P predefined by the protocol may be configured by higher layer signaling, or the candidate value configured by higher layer signaling may be indicated by physical layer signaling.

[0180] Example 5

[0181] If multiple subslot-based Physical Uplink Control Channels (PUCCHs) are configured in a slot, and another slot-based PUCCH or Physical Uplink Shared Channel (PUSCH) is configured in the same slot, at least one subslot-based PUCCH collides with the slot-based PUCCH / PUSCH in the time domain, e.g. Figure 4 shown.

[0182] Figure 4 Slot-based PUCCH / PUSCH based on some example embodiments of the disclosed technology are depicted.

[0183] Figure 4The PUCCH in a slot can carry hybrid automatic repeat request acknowledgment (HARQ-ACK) information, scheduling request (SR), or channel state information (CSI), and the PUSCH can carry CSI or data information. This embodiment is not limited to the scenario where the PUCCH / PUSCH collides with all sub-slot-based PUCCHs in the slot, and the conflicting channel priorities can be the same or different.

[0184] Methods for handling such conflicts include at least one of the following:

[0185] Method 1:

[0186] The slot-based PUCCH / PUSCH and the conflicting first subslot-based PUCCH meeting timeline are multiplexed according to existing methods. If a conflict still exists after multiplexing the two channels, the multiplexed channel is transmitted and the remaining subslot-based PUCCH(s) are discarded, or the slot-based PUCCH / PUSCH is discarded and all subslot-based PUCCHs are transmitted.

[0187] Method 2:

[0188] According to the existing method, slot-based PUCCH / PUSCH and conflicting first subslot-based PUCCH conference timeline and using PUCCH format 0, PUCCH format 2, PUCCH format 3 or PUCCH format 4 (non-PUCCH format 1) are multiplexed. If all subslot-based PUCCHs use PUCCH format 1, slot-based PUCCH / PUSCH is discarded and all subslot-based PUCCHs are transmitted, or slot-based PUCCH / PUSCH is transmitted and all subslot-based PUCCHs are discarded.

[0189] Method 3:

[0190] If the slot-based PUCCH uses PUCCH format 1 and carries SR information, the slot-based PUCCH / PUSCH and the colliding first subslot-based PUCCH conference timeline and using PUCCH format 0, PUCCH format 2, PUCCH format 3, or PUCCH format 4 (non-PUCCH format 1) are multiplexed according to the existing method. If all subslot-based PUCCHs that collide with the slot-based PUCCH carrying SR use PUCCH format 1, the slot-based PUCCH / PUSCH is discarded and all subslot-based PUCCHs are transmitted, or the slot-based PUCCH / PUSCH is transmitted and all subslot-based PUCCHs are discarded.

[0191] Method 4:

[0192] If the slot-based PUCCH uses PUCCH format 1 and carries SR information, the slot-based PUCCH / PUSCH and the conflicting first subslot-based PUCCH conference timeline and using PUCCH format 0, PUCCH format 2, PUCCH format 3, or PUCCH format 4 (non-PUCCH format 1) are multiplexed according to the existing method. If all subslot-based PUCCHs use format 1, the slot-based PUCCH / PUSCH is discarded and all subslot-based PUCCHs are transmitted, or the slot-based PUCCH / PUSCH is transmitted and all subslot-based PUCCHs are discarded.

[0193] Figure 5 Depicted are examples of temporal analysis of information messages including control transmission cancellation indications based on some example embodiments of the disclosed technology.

[0194] In some implementations, the starting time point of t0 may be the last symbol of a DCI message that carries a ULCI indication. In other implementations, the starting time point of t0 may be the last symbol of a last DCI message in a set of DCI messages to which the UE may respond. The set of DCI messages includes DCI messages that schedule the first transmission, the second transmission, and the third transmission (1, 2, and 3) and the DCI message that carries the ULCI indication.

[0195] Figure 6 Another example of controlling a temporal analysis of an information message including a transmission cancellation indication based on some example embodiments of the disclosed technology is depicted.

[0196] In some implementations, the end time point of t0 may be at the first symbol of the first uplink transmission that arrives first in the overlapping uplink transmission group. In other implementations, the end time point of t0 may be at the first symbol of the first uplink transmission that overlaps with the RUR in the overlapping uplink transmission group.

[0197] Figure 7 Another example of controlling a temporal analysis of an information message including a transmission cancellation indication based on some example embodiments of the disclosed technology is depicted.

[0198] In some implementations, the end time point of t0 may be at the first symbol of the first arriving high priority uplink transmission in the overlapping uplink transmission group.

[0199] Figure 8 Another example of controlling a temporal analysis of an information message including a transmission cancellation indication based on some example embodiments of the disclosed technology is depicted.

[0200] In some implementations, the end time point of t0 may be at the first symbol of the highest priority uplink transmission that overlaps with the RUR in the overlapping uplink transmission group.

[0205] Figure 11 Another example of controlling a temporal analysis of an information message including a transmission cancellation indication based on some example embodiments of the disclosed technology is depicted.

[0206] In some implementations, the end time point of t0 may be at the first symbol of the first uplink transmission that overlaps with the ULCI to indicate cancellation of resource overlap in the uplink transmissions with the overlap.

[0207] In other implementations, the end time point of t0 may be at the first symbol of the first uplink transmission that overlaps with the RUR and the ULCI indication to cancel the overlap of the uplink transmissions.

[0208] Figure 12 Another example of controlling a temporal analysis of an information message including a transmission cancellation indication based on some example embodiments of the disclosed technology is depicted.

[0209] In some implementations, the starting time point of t1 may be at the last symbol of the DCI message carrying the ULCI indication.

[0210] In some implementations, the starting time point of t1 may be at the last symbol of the last DCI message to which the UE may respond, corresponding to the last DCI message in a set of DCI messages, the set of DCI messages including the DCI messages scheduling the first transmission, the second transmission, and the third transmission (1, 2, and 3) and the DCI message carrying the ULCI indication.

[0211] In some implementations, the end time point of t1 may be that in the overlapping uplink transmissions, the first uplink transmission overlapping with the ULCI indication resource is 1, and the first symbol of the first uplink transmission overlaps with 1 and does not overlap with the ULCI indication resource.

[0212] In some implementations, the end time point of t1 may be in an overlapping uplink transmission, overlapping with a RUR, the first uplink transmission overlapping with a ULCI indicator resource is 1, the first uplink transmission overlapping with 1 and not overlapping with a ULCI indicator resource, the symbol

[0213] In some implementations, the execution order by the UE is as follows:

[0214] First, the UE determines whether the timeline is met and performs inter-UE cancellation first; if the timeline is not met, the corresponding operations are performed according to the DCI arrival order.

[0215] Next, the UE determines the timeline endpoint. This endpoint is the starting point of some uplink transmission. Based on this, it infers the timeline length. The UE waits until the inferred point. If a ULCI is received, the UE first performs an inter-UE cancellation. This is performed in the order in which the DCI arrives.

[0216] Figure 13 An example of a method of wireless communication based on some embodiments of the disclosed technology is depicted.

[0217] In some embodiments of the disclosed technology, a method of wireless communication includes: at 1310, receiving, by a first wireless device, one or more control information messages, at least one of the control information messages including a transmission cancellation indication indicating that a transmission previously scheduled for the first wireless device is to be canceled, and at 1320, performing, by the first wireless device, a temporal analysis of at least one of the control information messages including the transmission cancellation indication.

[0218] In some implementations, the temporal analysis includes determining, by the first wireless device, timeline information based on one or more control information messages and uplink transmissions scheduled by the control information or corresponding to a configuration authorization; and determining, by the first wireless device, whether the timeline information satisfies a predetermined condition.

[0219] In some implementations, the time analysis includes determining, by the first wireless device, a reference point in time based on a first symbol of each uplink transmission scheduled by one or more control information messages; and comparing, by the first wireless device, the reference point in time with an arrival timing of at least one control information message, the at least one control information message including a transmission cancellation indication indicating that a transmission previously scheduled for the first wireless device is to be canceled.
