Background
Currently, a User Equipment (UE) may send data to a network device according to an uplink PUSCH resource scheduled by an uplink configuration Grant (UplinkConfigured Grant). Since the uplink configuration grant is configured in advance for the UE by the network device through a specific signaling (e.g., Radio Resource Control (RRC) configuration information, etc.), the properties of some parameters in the uplink configuration grant may be deteriorated over time, which may further cause data transmission failure.
Currently, the network device may modify the parameter of the uplink configuration grant through RRC reconfiguration Information, and/or modify the parameter of the uplink configuration grant through an uplink configuration grant carried by Downlink Control Information (DCI) scrambled by a configuration scheduling radio network temporary identifier (CS-RNTI).
However, the method for modifying the parameters of the uplink configuration authorization through the RRC reconfiguration information needs to configure all the parameters of the uplink authorization, which requires a long configuration time; the method for modifying the parameters of the uplink configuration authorization through the uplink configuration authorization carried by the DCI scrambled by the CS-RNTI needs to increase additional signaling overhead. Thus, the above methods for modifying the parameters of the uplink configuration grant are not flexible enough.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
In the description of the embodiments of the present invention, unless otherwise specified, "a plurality" means two or more, for example, a plurality of processing units means two or more processing units; plural elements means two or more elements, and the like.
The Uplink Grant, also called Uplink Grant information, is used to indicate a sending resource of Uplink data, and includes an Uplink Dynamic Grant (Uplink Dynamic Grant) and an Uplink configuration Grant.
And after receiving the Uplink dynamic grant, the UE transmits data on a scheduled resource (Physical Uplink Shared Channel (PUSCH)) according to scheduling information of the Uplink dynamic grant.
And when the UE has data to be sent, the semi-continuous resource can be directly used, namely dynamic scheduling is not needed, so that the signaling interaction flow is reduced, the time delay can be reduced, and the method mainly aims at low-time-delay services and periodic services.
The uplink configuration authorization is divided into two types, namely type 1 and type 2.
The uplink configuration authorization type 1 is configured by the RRC configuration information, and after obtaining the RRC configuration information, the UE can know that the type 1 is the uplink configuration authorization type 1 through an independent domain belonging to the type 1 and included in the RRC configuration information, so that the uplink configuration authorization type 1 is immediately validated.
The uplink configuration authorization type 2 is configured by a parameter of the common part of the RRC configuration information (at this time, the uplink configuration authorization in an inactive state), and is activated by the uplink configuration authorization carried by DCI format (format)0-0 scrambled by CS-RNTI or DCI format0-1, where the general DCI indicates information of some domains, and if there is no some domain in DCI format 0-0 or DCI format0-1, a default value is used. And the uplink configuration authorization type 2 is taken into effect after the DCI is activated.
Each UE has at least two authentication keys, namely Cell RNTI (Cell RNTI, C-RNTI) and CS-RNTI. The C-RNTI is used for dynamic scheduling (namely DCI used for scrambling uplink dynamic authorization of bearer), and the CS-RNTI is used for activating and deactivating semi-persistent scheduling (namely DCI used for scrambling uplink configuration authorization of bearer activation and deactivation). When the UE decodes the uplink DCI, the C-RNTI is used for not decoding the DCI, but the CS-RNTI is used for decoding the DCI, so that the DCI is used for activating the uplink configuration authorization.
The method for activating and deactivating the uplink configuration authorization type 2 comprises the following steps:
when a specific field in the corresponding DCI format is set to a specific value, the UE considers this to be a valid activation or deactivation. If the UE considers this to be an invalid activation or deactivation, the UE will discard all information in the invalid DCI.
The method for modifying the parameters of the uplink configuration authorization comprises the following steps: the parameters of the uplink configuration authorization can be modified directly without deactivation; the parameters of the uplink configuration authorization type 1 are modified through RRC reconfiguration information; the parameter of the uplink configuration authorization type 2 is modified through RRC reconfiguration information and/or DCI scrambled by CS-RNTI.
The embodiment of the invention provides a parameter modification method, wherein UE (user equipment) can receive target uplink dynamic authorization from network equipment; updating the target uplink configuration authorization according to the target uplink dynamic authorization; and transmitting the target data according to the updated target uplink configuration authorization. By the scheme, the UE can update the target uplink configuration authorization according to the target uplink dynamic authorization without modifying the parameters of the uplink configuration authorization through the RRC reconfiguration information and/or the uplink configuration authorization carried by the DCI scrambled by the CS-RNTI, so that the parameters of the uplink configuration authorization can be rapidly modified under the condition of not increasing additional signaling overhead, and the flexibility of modifying the parameters of the uplink configuration authorization can be improved.
The technical scheme provided by the invention can be applied to various communication systems, such as a 5G communication system, a future evolution system, or a plurality of communication convergence systems and the like. A variety of application scenarios may be included, for example, scenarios such as Machine to Machine (M2M), D2M, macro and micro Communication, enhanced Mobile Broadband (eMBB), ultra high reliability and ultra Low Latency Communication (urrllc), and mass internet of things Communication (mtc).

Based on the communication system shown in fig. 1, an embodiment of the present invention provides a parameter modification method, which may include steps 201 to 205 described below, as shown in fig. 2.
Step 201, the network device sends a target uplink dynamic grant to the UE.
Wherein, the target uplink dynamic authorization is used for the UE to update the target uplink configuration authorization.
Optionally, in the embodiment of the present invention, the target uplink dynamic grant is carried through a DCI or a media access Control-Control Element (MAC-CE) command. The target uplink dynamic grant may also be carried by other information, and the embodiment of the present invention is not limited.
The embodiment of the invention increases the information for bearing the uplink dynamic authorization.
In the embodiment of the present invention, the target uplink dynamic grant is an uplink grant carried by information (DCI or MAC-CE command) scrambled by a first Radio Network Temporary Identifier (RNTI).
The first RNTI is not a CS-RNTI, and the first RNTI may be any one of: cell RNTI (C-RNTI), Modulation and coding scheme C-RNTI (Modulation and coding scheme C-RNTI, MCS-C-RNTI), System Information RNTI (System Information RNTI, SI-RNTI), Semi-Persistent Channel State Information RNTI (SP-CSI-RNTI), Inactive RNTI (Inactive RNTI, I-RNTI), interrupt RNTI (int-RNTI), Transmit Power Control-Sounding Reference symbol RNTI (Transmit Power Control-Sounding Reference symbol-RNTI, tpc-SRS-RNTI), Transmit Power Control-Physical Uplink Control Channel RNTI (Transmit Power Control-Physical Uplink Control Channel-RNTI, tpc-PUCCH-RNTI), Transmit Power Control-Physical Uplink Shared Channel-RNTI (Transmission Power Control-Physical Uplink Channel-RNTI), tpc-PUSCH-RNTI), paging RNTI (P-RNTI), Slot Format indicator RNTI (Slot Format Indication RNTI, SFI-RNTI), source-C-RNTI (source-C-RNTI), random Access response RNTI (RA-RNTI), and Temporary C-RNTI (Temporary C-RNTI).
Step 202, the UE receives a target uplink dynamic grant from the network device.
Step 203, the UE updates the target uplink configuration grant according to the target uplink dynamic grant.
Optionally, in this embodiment of the present invention, for a serving cell, when the UE includes one uplink configuration grant (for example, in Rel-15 specification), the target uplink configuration grant is the one uplink configuration grant.
Optionally, in this embodiment of the present invention, for a serving cell, when the UE includes at least two uplink configuration grants, the target uplink configuration grant is: at least one uplink configuration grant of the at least two uplink configuration grants; or, the target uplink configuration grant is: and the uplink configuration authorization meeting the target condition in the at least two uplink configuration authorizations. Wherein the target condition comprises at least one of: the spatial beam information is the same as the spatial beam information of the target uplink dynamic authorization, and the identity identification information is matched with the identity identification information of the target uplink dynamic authorization.
Wherein the spatial beam information may include at least one of: resource indication (srs (sounding signal) resource indicator, SRI) information, panel (panel) ID; other information may also be included, and embodiments of the present invention are not limited. And when the target condition includes that the spatial beam information of the uplink configuration grant is the same as the spatial beam information of the target uplink dynamic grant, the spatial beam information of the uplink configuration grant is not allowed to be modified.
In the embodiment of the present invention, the identification information includes any one of the following items: an uplink grant (uplinkgunt) ID, a hybrid automatic Repeat request process (harq process) ID. The identity identification information may also include other information for indicating an identity of the uplink grant, which may be determined specifically according to actual usage requirements, and the embodiment of the present invention is not limited.
The embodiment of the invention provides various kinds of identity identification information.
In the embodiment of the present invention, the identity identification information of the target uplink configuration authorization is matched with the identity identification information of the target uplink dynamic authorization, which may specifically refer to: the identity identification information of the target uplink configuration authorization is the same as the identity identification information of the target uplink dynamic authorization, or the identity identification information of the target uplink configuration authorization and the identity identification information of the target uplink dynamic authorization have a certain preset relationship, or the similarity between the identity identification information of the target uplink configuration authorization and the identity identification information of the target uplink dynamic authorization is greater than or equal to a preset threshold value. For example, the preset threshold may be 95%, that is, if the similarity between the identification information of the target uplink configuration grant and the identification information of the target uplink dynamic grant is greater than or equal to 95%, the identification information of the target uplink configuration grant matches with the identification information of the target uplink dynamic grant.
It is understood that, in the case that the UE includes at least two uplink configuration grants, the target uplink configuration grant includes, but is not limited to, the following four possibilities:
the first possibility is: the target uplink configuration grant is at least one (arbitrary) uplink configuration grant of the at least two uplink configuration grants. For example, in a case that the UE includes two uplink configuration grants (taking uplink configuration grant 1 and uplink configuration grant 2 as an example), the target uplink configuration grant is uplink configuration grant 1 and uplink configuration grant 2, or the target uplink configuration grant is uplink configuration grant 1 or uplink configuration grant 2.
In a second possibility, the target uplink configuration grant is an uplink configuration grant with spatial beam information (target condition) identical to that of the target uplink dynamic grant. For example, when the UE includes two uplink configuration grants (taking uplink configuration grant 1 and uplink configuration grant 2 as an example), where the spatial beam information of the uplink configuration grant 1 is the same as the spatial beam information of the target uplink dynamic grant, and the spatial beam information of the uplink configuration grant 2 is different from the spatial beam information of the target uplink dynamic grant, the target uplink configuration grant is the uplink configuration grant 1.
In a third possibility, the target uplink configuration grant is an uplink configuration grant whose identification information matches (target condition) the identification information of the target uplink dynamic grant. For example, in a case that the UE includes two uplink configuration grants (taking uplink configuration grant 1 and uplink configuration grant 2 as an example), where the identification information of the uplink configuration grant 1 does not match the identification information of the target uplink dynamic grant, and the identification information of the uplink configuration grant 2 matches the identification information of the target uplink dynamic grant, the target uplink configuration grant is the uplink configuration grant 2.
A fourth possibility: the target uplink configuration authorization is as follows: the spatial beam information is the same as the spatial beam information of the target uplink dynamic authorization, and the identification information is matched with the identification information of the target uplink dynamic authorization (target condition) for uplink configuration authorization. For example, in a case that the UE includes two uplink configuration grants (taking uplink configuration grant 1, uplink configuration grant 2, and uplink configuration grant 3 as an example), where spatial beam information of the uplink configuration grant 1 is the same as spatial beam information of the target uplink dynamic grant, but identification information of the uplink configuration grant 1 is not matched with identification information of the target uplink dynamic grant; the spatial beam information of the uplink configuration authorization 2 is different from the spatial beam information of the target uplink dynamic authorization, but the identification information of the uplink configuration authorization 2 is matched with the identification information of the target uplink dynamic authorization; the spatial beam information of the uplink configuration authorization 3 is the same as the spatial beam information of the target uplink dynamic authorization, and the identification information of the uplink configuration authorization 3 is matched with the identification information of the target uplink dynamic authorization; the target uplink configuration grant is the uplink configuration grant 3.
It should be noted that, no matter which of the four possibilities is the target uplink configuration grant, the number of the target uplink configuration grants is not limited in the embodiment of the present invention.
It should be noted that, in the embodiment of the present invention, the target condition may be configured by the network device for the UE, may also be agreed by a protocol (also referred to as a communication protocol specification), may also be customized by the UE, and may specifically be determined according to an actual use requirement, which is not limited in the embodiment of the present invention.
The embodiment of the invention provides a plurality of methods for determining target uplink configuration authorization.
Optionally, in the embodiment of the present invention, the UE may update part of or all of the parameters of the target uplink configuration authorization according to the target uplink dynamic authorization; the UE may also update parameters of all frequency domain resources or parameters of a part of frequency domain resources scheduled by the target uplink configuration grant according to the target uplink dynamic grant, or may be in other cases, and may specifically be determined according to actual usage requirements, which is not limited in the embodiment of the present invention.
Illustratively, in the embodiment of the present invention, the step 203 may be specifically implemented by the following step 203 a.
Step 203a, the UE modifies the parameter information of the target parameter of the target uplink configuration authorization into target information.
Wherein, the target information is parameter information of target parameters of the target uplink dynamic authorization.
Optionally, in the embodiment of the present invention, the target parameter may be configured by the network device for the UE, may also be agreed by a protocol, may also be customized by the UE, and may specifically be determined according to an actual use requirement, which is not limited in the embodiment of the present invention.
For example, taking the target parameter as the agreement, the agreement target parameter may be a parameter that is overlapped with all or part of the parameters of the target uplink configuration grant.
Optionally, the target parameter includes at least one of the following items (i.e. including any one, any two, any three, … …, any m (m is greater than or equal to 1 and less than or equal to 9) … … or all of the following items, which may be determined according to actual use requirements, and the embodiments of the present invention are not limited by the following items): modulation coding information, Transport Block Set (TBS), Transport Precoding Matrix Indicator (TPMI), Rank number (Rank number), antenna port number (antenna port), Demodulation Reference Signal (DMRS) configuration information, spatial indication information, power control related information, and frequency hopping related information.
The Modulation and Coding Scheme (MCS) may be Modulation and Coding Scheme (Modulation and Coding Scheme, MCS), or other information, which is not limited in the embodiment of the present invention.
Among them, TPMI may also be referred to as codebook index. Rank number may also be referred to as number of layers. The number of antenna ports may also be referred to as the DMRS port number.
The spatial indication information may be SRI information, or may be other information, which is not limited in the embodiment of the present invention.
The Power Control related information may be a Transmit Power Control (TPC) command (tpccoommand for scheduled PUSCH) for scheduling a Physical Uplink Shared Channel (PUSCH), or may be other information, which is not limited in the embodiment of the present invention.
The information related to Frequency hopping may be a Frequency hopping flag (Frequency hopping flag), a Frequency hopping offset (Frequency hopping offset), or other information, and the embodiment of the present invention is not limited thereto.
Optionally, the target parameter in the target uplink configuration grant includes: and part or all of the target parameters corresponding to the target frequency domain resources. Wherein the target frequency domain resource is: the target uplink configures the frequency domain resource authorized to be scheduled, and the frequency domain resource occupied or scheduled by the target uplink dynamic authorization is overlapped with the resource.
It can be understood that the step 203a may specifically be: and the UE modifies the parameter information of part or all of the target parameters corresponding to the target frequency domain resources authorized by the target uplink configuration into target information. In this case, the wideband frequency domain resource may be targeted, or the subband frequency domain resource may be targeted, and the embodiment of the present invention is not limited.
In the embodiment of the invention, the target parameters are modified according to part or all of the target parameters corresponding to the target frequency domain resources authorized by the target uplink configuration, so that the modification of the parameters authorized by the uplink configuration is more flexible.
Further optionally, in a case that the target parameter is a TPMI, the TPMI authorized by the target uplink configuration includes: TPMI corresponding to part or all of the subbands in the target frequency domain resource.
It will be appreciated that for sub-band frequency domain resources, different sub-band frequency domain resources correspond to different TPMI. The step 203a may specifically be: and the UE modifies the TPMI corresponding to the partial (or all) sub-bands corresponding to the target frequency domain resources authorized by the target uplink configuration into the TPMI corresponding to the partial (or all) sub-bands corresponding to the target frequency domain resources dynamically authorized by the target uplink.
In the embodiment of the invention, aiming at the sub-band frequency domain resources, the modification of the parameters of the uplink configuration authorization is more flexible.
Optionally, the UE may modify the TPMI of the sub-band of which the overlap ratio is greater than or equal to the second threshold in the frequency domain resource scheduled by the target uplink configuration grant to the TPMI of the target uplink dynamic grant. The overlap ratio is a ratio of a sub-band (hereinafter referred to as sub-band 1) of the target frequency domain resource to a sub-band including the sub-band 1 in the frequency domain resource scheduled by the target uplink configuration grant. The second threshold value is a value greater than or equal to 0 and less than or equal to 1.
Illustratively, the frequency domain resource scheduled by the target uplink configuration grant is 0-50MHZ, and is divided into 3 sub-bands, which are 0-20MHZ, 20-40MHZ and 40-50MHZ, respectively, and each sub-band corresponds to TPMI 1, TPMI 2 and TPMI 3. The frequency domain resource scheduled by the target uplink dynamic grant is 30-90MHz, and is divided into 3 sub-bands which are respectively 30-40MHz, 40-70MHz and 70-90MHz, and each sub-band corresponds to TPMI 4, TPMI 5 and TPMI 6. The target frequency domain resource is 30-50MHz, wherein the partially overlapped sub-band 30-40MHz (overlap ratio is 50%) and the fully overlapped sub-band 40-50MHz (overlap ratio is 1), the UE may modify the TPMI of the sub-band 30-40MHz of the uplink configuration grant scheduling from TPMI 2 to TPMI 4, and modify the TPMI of the sub-band 40-50MHz of the uplink configuration grant scheduling from TPMI 3 to TPMI 5 (the UE may also modify only the TPMI of the sub-band 40-50MHz of the uplink configuration grant scheduling from TPMI 3 to TPMI 5).
The embodiment of the invention provides a plurality of methods for updating the target uplink configuration authorization.
Optionally, in this embodiment of the present invention, the step 203 may be specifically implemented by the following step 203 b.
Step 203b, the UE updates the target uplink configuration grant at the target update time according to the target uplink dynamic grant.
Optionally, in this embodiment of the present invention, the step 203a may be specifically implemented by the following step 203a 1.
Step 203a1, in the target update time, the UE modifies the parameter information of the target parameter of the target uplink configuration authorization into the target information.
It should be noted that the update time (e.g., the target update time) corresponding to one uplink dynamic grant may be configured by the network device for the UE, may also be agreed by a protocol, may also be customized by the UE, and may specifically be determined according to actual use requirements, which is not limited in the embodiment of the present invention.
Wherein, the update time is agreed by the protocol, and may include: the value of the agreed update time or the calculation formula of the agreed update time may be determined according to actual use requirements, and the embodiment of the present invention is not limited.
Optionally, the target update time includes any one of: at least one time unit after a first position of a first target symbol in a time domain resource occupied by the target uplink dynamic grant, a second position of a second target symbol in the time domain resource scheduled by the target uplink dynamic grant, at least one time unit after the second position of the second target symbol in the time domain resource scheduled by the target uplink dynamic grant, and at least one time unit before the second position of the second target symbol in the time domain resource scheduled by the target uplink dynamic grant.
In the embodiment of the present invention, the unit of time includes, but is not limited to, any of the following: second, symbol (symbol), slot (slot).
Optionally, the first target symbol may be any one symbol in a time domain resource occupied by the target uplink dynamic grant, and may be specifically determined according to an actual use requirement, which is not limited in the embodiment of the present invention.
Illustratively, the first target symbol is: and the target uplink dynamic grant occupies the first symbol or the last symbol in the time domain resource.
Optionally, the first position of the first target symbol may be any position of the first target symbol, and may be determined specifically according to actual use requirements, which is not limited in the embodiment of the present invention.
Illustratively, the first position of the first target symbol is: a starting position or an ending position of the first target symbol.
Illustratively, the first position of the first target symbol is any one of: a starting position of a first symbol in the time domain resource occupied by the target uplink dynamic grant, an ending position of the first symbol in the time domain resource occupied by the target uplink dynamic grant, a starting position of a last symbol in the time domain resource occupied by the target uplink dynamic grant, and an ending position of the last symbol in the time domain resource occupied by the target uplink dynamic grant.
For example, as shown in fig. 3, in a case that the network device does not receive the first data sent by the UE through the resource marked as "2" of the target uplink configuration grant scheduling, the UE receives an uplink dynamic grant a for retransmitting the first data. And updating the parameters TPMI and SRI of the target uplink configuration authorization into the parameters TPMI and SRI of the uplink dynamic authorization a by the UE at the end position of the n symbols after the end position of the last symbol of the time domain resource occupied by the uplink dynamic authorization a.
For example, as shown in fig. 4, the UE includes two uplink configuration grants, which are an uplink configuration grant a and an uplink configuration grant b, respectively. And in the case that the network equipment does not receive the second data sent by the UE through the resource marked as '3' scheduled by the uplink configuration grant a, the UE receives the uplink dynamic grant a for retransmitting the second data. Since the identification information (HARQ process ID ═ 1) of the uplink dynamic grant a is the same as the identification information (HARQ process ID ═ 1) of the uplink configuration grant a (the scheduled resource marked as "3"), the UE updates the parameters TPMI and SRI of the uplink configuration grant a to the parameters TPMI and SRI of the uplink dynamic grant a at the end position of n symbols after the end position of the last symbol of the time domain resource occupied by the uplink dynamic grant a according to the identification information of the uplink dynamic grant a being the HARQ process ID.
Optionally, the second target symbol may be any one symbol in the time domain resource scheduled by the target uplink dynamic grant, and may be specifically determined according to an actual use requirement, which is not limited in the embodiment of the present invention.
Illustratively, the second target symbol is: and the target uplink dynamically authorizes the first symbol or the last symbol in the scheduled time domain resource.
Optionally, the second position of the second target symbol may be any position of the second target symbol, and may be determined specifically according to an actual use requirement, which is not limited in the embodiment of the present invention.
Illustratively, the second position of the second target symbol is: a start position or an end position of the second target symbol.
Illustratively, the second position of the second target symbol is any one of: the starting position of the first symbol in the time domain resource scheduled by the target uplink dynamic grant, the ending position of the first symbol in the time domain resource scheduled by the target uplink dynamic grant, the starting position of the last symbol in the time domain resource scheduled by the target uplink dynamic grant, and the ending position of the last symbol in the time domain resource scheduled by the target uplink dynamic grant.
For example, as shown in fig. 5, in a case that the network device does not receive the first data sent by the UE through the resource marked as "2" of the target uplink configuration grant scheduling, the UE receives an uplink dynamic grant a for retransmitting the first data. And updating the parameters TPMI and SRI of the target uplink configuration authorization into the parameters TPMI and SRI of the uplink dynamic authorization a by the UE at the end position of n symbols after the end position of the last symbol of the time domain resource scheduled by the uplink dynamic authorization a.
For example, as shown in fig. 6 or fig. 7, the UE includes two uplink configuration grants, i.e., an uplink configuration grant a and an uplink configuration grant b. The identification information of the uplink configuration authorization a is an uplink authorization ID (1), and the identification information of the uplink configuration authorization b is an uplink authorization ID (0). And in the case that the network equipment does not receive the third data transmitted by the resource marked as '4' scheduled by the UE through the uplink configuration grant b, the UE receives the uplink dynamic grant b for retransmitting the third data. Since the identification information (uplink grant ID ═ 0) of the uplink dynamic grant b is the same as the identification information (uplink grant ID ═ 0) of the uplink configuration grant b, the UE updates the parameters TPMI and SRI of the uplink configuration grant b to the parameters TPMI and SRI of the uplink dynamic grant b at the end positions of n symbols after the end position of the last symbol of the time domain resource scheduled by the uplink dynamic grant b.
In the embodiment of the present invention, the identification information of the uplink dynamic authorization may be carried in at least one of the following items: and the resources occupied by the uplink dynamic authorization and the resources scheduled by the uplink dynamic authorization.
For example, as shown in fig. 8, the UE includes two uplink configuration grants, which are an uplink configuration grant a and an uplink configuration grant b, respectively. And in the case that the network equipment does not receive the third data transmitted by the resource marked as '4' scheduled by the UE through the uplink configuration grant b, the UE receives the uplink dynamic grant b for retransmitting the third data. Since the identification information (HARQ process ID ═ 8) of the uplink dynamic grant b is the same as the identification information (HARQ process ID ═ 8) of the uplink configuration grant b (the scheduled resource marked as "4"), the UE updates the parameters TPMI and SRI of the uplink configuration grant b to the parameters TPMI and SRI of the uplink dynamic grant b at the end position of n symbols after the end position of the last symbol of the time domain resource scheduled by the uplink dynamic grant b according to the identification information of the uplink dynamic grant b being the HARQ process ID.
In the embodiment of the invention, a plurality of possibilities of the first target symbol, the first position, the second target symbol and the second position are provided, so that a more updating time can be obtained.
In the embodiment of the present invention, when the target update time is at least one time unit after the first position of the first target symbol in the time domain resource occupied by the target uplink dynamic grant or the target update time is at least one time unit before the second position of the second target symbol in the time domain resource scheduled by the target uplink dynamic grant, the UE may not have yet analyzed the parameter of the target uplink dynamic grant, and thus the parameter modification may not be completed at the target update time.
In order to solve the problem that the parameter modification cannot be completed in the target update time, an embodiment of the present invention provides the following method:
for the case that the target update time is at least one time unit after the first position of the first target symbol in the time domain resource occupied by the target uplink dynamic grant: if at least one time unit after the first position of the first target symbol in the time domain resources occupied by the target uplink dynamic grant is N time units after the end position of the last symbol of the time domain resources occupied by the target uplink dynamic grant, the target update time is at least one time unit after the first position of the first target symbol in the time domain resources occupied by the target uplink dynamic grant; if at least one time unit after the first position of the first target symbol in the time domain resources occupied by the target uplink dynamic grant is before or the same as N time units after the end position of the last symbol of the time domain resources occupied by the target uplink dynamic grant, the target update time is the end position of N time units after the end position of the last symbol of the time domain resources occupied by the target uplink dynamic grant.
For the situation that the target update time is at least one time unit before the second position of the second target symbol in the time domain resource scheduled by the target uplink dynamic grant, if the at least one time unit before the second position of the second target symbol in the time domain resource scheduled by the target uplink dynamic grant is N time units after the end position of the last symbol of the time domain resource occupied by the target uplink dynamic grant, the target update time is at least one time unit before the second position of the second target symbol in the time domain resource scheduled by the target uplink dynamic grant; if at least one time unit before the second position of the second target symbol in the time domain resource scheduled by the target uplink dynamic grant is before or the same as N time units after the end position of the last symbol of the time domain resource occupied by the target uplink dynamic grant, the target update time is the end position of N time units after the end position of the last symbol of the time domain resource occupied by the target uplink dynamic grant.
Alternatively, to solve the above problem that the parameter modification cannot be completed at the target update time, the embodiment of the present invention may further define at least one time unit after the first position of the first target symbol and at least one time unit before the second position of the second target symbol.
Optionally, at least one time unit after the first position of the first target symbol: after N time units after the end position of the last symbol of the time domain resource occupied by the target uplink dynamic grant; or, at least one time unit prior to the second position of the second target symbol: after N time units after the end position of the last symbol of the time domain resource occupied by the target uplink dynamic grant; n is a positive integer.
Optionally, the N time units may be agreed upon by the protocol.
In the embodiment of the present invention, the ranges of at least one time unit after the first position of the first target symbol and at least one time unit before the second position of the second target symbol are further defined, and the success rate of parameter modification can be ensured to a certain extent.
Optionally, the N time units may be any one of the following: the time (marked as the first time) required by the UE for receiving the target uplink dynamic grant and analyzing the parameter information from the target uplink dynamic grant; and the time (denoted as the second time) required by the UE agreed by the protocol to receive the uplink dynamic grant and analyze the parameter information from the uplink dynamic grant. The N time units may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.
Optionally, the N time units may be: a maximum of the first time and the second time. For example, if the first time is greater than or equal to the second time, the N time units are the first time; if the first time is less than the second time, the N time units are the second time.
In the embodiment of the invention, the possibility of multiple N time units is provided, and the success rate of parameter modification is further ensured.
Optionally, in a preset time period, the UE receives at least one uplink dynamic grant from the network device, and when the at least one uplink dynamic grant can be used to update the target uplink configuration grant, the UE may sequentially modify the target uplink configuration grant according to a first order according to each uplink dynamic grant in the at least one uplink dynamic grant, where the first order may be an order arranged according to an update time corresponding to each uplink dynamic grant; the UE may also select one uplink dynamic grant from the at least one uplink dynamic grant according to a preset rule, to obtain the target uplink dynamic grant, and update the target uplink configuration grant according to the target uplink dynamic grant.
It should be noted that the preset time period and the preset rule may be configured by the network device, may also be agreed by a protocol, may also be customized by the UE, and may specifically be determined according to actual use requirements, which is not limited in the embodiment of the present invention.
In the embodiment of the present invention, in a preset time period, when the UE receives at least one uplink dynamic grant from the network device, the method for the UE to select a target uplink dynamic grant from the at least one uplink dynamic grant according to a preset rule may include, but is not limited to, the following possible cases.
In a first possible case, the target uplink dynamic grant is: any one of the at least one first uplink dynamic grant (i.e., the at least one uplink dynamic grant described above); each first uplink dynamic grant corresponds to an update time.
It can be understood that the UE selects an uplink dynamic grant from the at least one first uplink dynamic grant at will, that is, obtains a target uplink dynamic grant, and updates the target uplink configuration grant according to the target uplink dynamic grant.
In a second possible case, the target uplink dynamic grant is: at least one uplink dynamic grant (i.e. the at least one uplink dynamic grant) satisfying a first condition; wherein the first condition is: the updating time is closest to the time domain resource scheduled by the target uplink configuration authorization, and is before the time domain resource scheduled by the target uplink configuration authorization; each first uplink dynamic grant corresponds to an update time.
The distance between the update time and the time domain resource scheduled by the target uplink configuration grant may be a distance between the update time and a starting position of a first symbol of the time domain resource scheduled by the target uplink configuration grant, or may be other feasible conditions, and the embodiment of the present invention is not limited.
It can be understood that the UE performs a primary screening on the at least one uplink dynamic grant to obtain a target uplink dynamic grant. Specifically, the UE selects an uplink dynamic grant satisfying a first condition (that is, the update time is closest to the time domain resource scheduled by the target uplink configuration grant and is before the time domain resource scheduled by the target uplink configuration grant) from the at least one first uplink dynamic grant, that is, the target uplink dynamic grant is obtained, and updates the target uplink configuration grant according to the target uplink dynamic grant.
For example, as shown in fig. 9, the UE receives two uplink dynamic grants (i.e. the at least one first uplink dynamic grant) from the network device, which are an uplink dynamic grant a and an uplink dynamic grant B, and updates the time to be the end position of n symbols after the end position of the last symbol of the time domain resource scheduled by the uplink dynamic grant. Wherein, the update time 1 corresponding to the uplink dynamic grant a and the update time 2 corresponding to the uplink dynamic grant B are both before the time domain resource scheduled by the target uplink configuration grant (next time) (the reference "6" in the figure indicates that the target uplink configuration grant is the resource scheduled next time), but the update time corresponding to the uplink dynamic grant a is closest to the time domain resource scheduled by the target uplink configuration grant, so that the target uplink dynamic grant is the uplink dynamic grant a, and the UE modifies the parameters TPMI and SRI of the target uplink configuration grant to the parameters TPMI and SRI of the uplink dynamic grant a.
It should be noted that, if there is one uplink dynamic grant meeting the first condition, the target uplink dynamic grant may be the one uplink dynamic grant meeting the first condition; if there are multiple uplink dynamic grants meeting the first condition, the target uplink dynamic grant may be the multiple uplink dynamic grants meeting the first condition, and the target uplink dynamic grant may also be any one of the multiple uplink dynamic grants meeting the first condition.
In a third possible case, the target uplink dynamic grant is: and the uplink dynamic grant meeting the second condition in the at least one second uplink dynamic grant (namely the at least one uplink dynamic grant).
Optionally, any one of the second conditions: the physical resource block PRB index of the first frequency domain position in the occupied or scheduled frequency domain resources is minimum; the PRB index of the first frequency domain position is maximum; the distance between the second frequency domain position in the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration authorization is closest; the PRB index of the first frequency domain position in the uplink dynamic grant with the closest distance between the second frequency domain position and the frequency domain resource scheduled by the target uplink configuration grant is the smallest; the PRB index of the first frequency domain position in the uplink dynamic grant with the second frequency domain position and the closest distance to the frequency domain resource scheduled by the target uplink configuration grant is the largest; the distance between the second frequency domain position in the uplink dynamic grant with the maximum PRB index of the first frequency domain position and the frequency domain resource scheduled by the target uplink configuration grant is the closest; and the distance between the second frequency domain position in the uplink dynamic grant with the minimum PRB index of the first frequency domain position and the frequency domain resource scheduled by the target uplink configuration grant is closest.
The second condition may also include other possible conditions, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.
The first frequency domain position may be a starting position, an ending position, or a middle position in the frequency domain resource occupied or scheduled by the uplink dynamic grant, or may be another feasible position, which is not limited in the embodiment of the present invention.
The second frequency domain position may be a starting position, an ending position, or a middle position in the frequency domain resource occupied or scheduled by the uplink dynamic grant, or may be another feasible position, which is not limited in the embodiment of the present invention. The distance between the second frequency domain position in the frequency domain resources occupied or scheduled by the uplink dynamic grant and the frequency domain resources scheduled by the target uplink configuration grant may be: and the distance between the second frequency domain position in the frequency domain resources occupied or scheduled by the uplink dynamic grant and the third frequency domain position of the frequency domain resources scheduled by the target uplink configuration grant. The third frequency domain position may be a starting position, an ending position, or an intermediate position in the frequency domain resource for which the target uplink configuration is authorized to be scheduled, or may be another feasible position, which is not limited in the embodiment of the present invention.
It is understood that the third possible scenario includes, but is not limited to, the following 7 scenarios:
in case 1, the second condition is that a Physical Resource Block (PRB) index (index) of the first frequency domain position in the occupied or scheduled frequency domain resources is minimum.
In case 2, the second condition is that the PRB index of the first frequency-domain location in the occupied or scheduled frequency-domain resource is maximum.
In case 3, the second condition is that the distance between the second frequency domain position in the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant is closest.
In case 4, the second condition is that, in the uplink dynamic grant with the closest distance between the second frequency domain position in the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant, the PRB index of the first frequency domain position in the occupied or scheduled frequency domain resource is the smallest.
In case 5, the second condition is that, in the uplink dynamic grant with the closest distance between the second frequency domain position in the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant, the PRB index of the first frequency domain position in the occupied or scheduled frequency domain resource is the largest.
In case 6, the second condition is that, in the uplink dynamic grant with the largest PRB index of the first frequency-domain position in the occupied or scheduled frequency-domain resource, the distance between the second frequency-domain position in the occupied or scheduled frequency-domain resource and the frequency-domain resource scheduled by the target uplink configuration grant is the closest.
In case 7, the second condition is that, in the uplink dynamic grant with the minimum PRB index of the first frequency-domain position in the occupied or scheduled frequency-domain resource, the distance between the second frequency-domain position in the occupied or scheduled frequency-domain resource and the frequency-domain resource scheduled by the target uplink configuration grant is the closest.
It can be understood that, for any one of the cases 1 to 3, the UE performs one screening on the at least one uplink dynamic grant to obtain a target uplink dynamic grant. Taking the case 3 as an example for illustration, specifically, the UE selects an uplink dynamic grant satisfying a second condition (that a second frequency domain position in the occupied or scheduled frequency domain resource is closest to the frequency domain resource scheduled by the target uplink configuration grant) from the at least one second uplink dynamic grant, that is, the target uplink dynamic grant is obtained, and updates the target uplink configuration grant according to the target uplink dynamic grant.
It can be understood that, for any one of the cases 4-7, the UE performs twice screening on the at least one uplink dynamic grant to obtain a target uplink dynamic grant. Taking the case 4 as an example, specifically, the UE selects an uplink dynamic grant (marked as at least one third uplink dynamic grant) satisfying the condition 1 (the distance between the second frequency domain position in the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant is closest), and then selects an uplink dynamic grant satisfying the condition 2 (the PRB index of the first frequency domain position in the occupied or scheduled frequency domain resource is minimum) from the at least one third uplink dynamic grant, so as to obtain the target uplink dynamic grant satisfying the second condition corresponding to the case 4, and update the target uplink configuration grant according to the target uplink dynamic grant.
It should be noted that, if there is one uplink dynamic grant meeting the second condition, the target uplink dynamic grant may be the one uplink dynamic grant meeting the second condition; if there are multiple uplink dynamic grants meeting the second condition, the target uplink dynamic grant may be the multiple uplink dynamic grants meeting the second condition, and the target uplink dynamic grant may also be any one of the multiple uplink dynamic grants meeting the second condition.
In combination with the second possible scenario and the fourth possible scenario, the at least one first uplink dynamic grant is: and the uplink dynamic grant meeting the second condition in the at least one second uplink dynamic grant (namely the at least one uplink dynamic grant).
For the description of the first condition, reference may be made to the description of the first condition in the second possible case, and details are not repeated here.
For the description of the second condition, reference may be made to the description of the second condition in the third possible case, and details are not repeated here.
It can be understood that, when the second condition is any one of the cases 1 to 3, the UE successively performs twice screening on the at least one uplink dynamic grant to obtain a target uplink dynamic grant. Taking the case 3 as an example for illustration, specifically, the UE selects an uplink dynamic grant satisfying a second condition (that a second frequency domain position in the occupied or scheduled frequency domain resource is closest to the frequency domain resource scheduled by the target uplink configuration grant) from the at least one second uplink dynamic grant, that is, obtains at least one first uplink dynamic grant; and then selecting an uplink dynamic grant meeting a first condition (the update time is closest to the time domain resource scheduled by the target uplink configuration grant and is before the time domain resource scheduled by the target uplink configuration grant) from the at least one first uplink dynamic grant, so as to obtain a target uplink dynamic grant, and updating the target uplink configuration grant according to the target uplink dynamic grant. That is, the UE first screens the at least one uplink dynamic grant according to the second condition to obtain a plurality of uplink dynamic grants, and then screens the plurality of uplink dynamic grants according to the first condition to obtain the target uplink dynamic grant.
It can be understood that, when the second condition is any one of the cases 4 to 7, the UE successively performs three screening operations on the at least one uplink dynamic grant to obtain a target uplink dynamic grant. Taking the case 4 as an example, specifically, the UE selects (through twice screening) the uplink dynamic grant satisfying the second condition (among uplink dynamic grants occupying or closest to the frequency-domain resource scheduled by the target uplink configuration grant, the PRB index of the first frequency-domain position in the occupied or scheduled frequency-domain resource is the smallest) from the at least one second uplink dynamic grant (refer to the above-mentioned description related to the third possible case, which is not described herein again), that is, obtains at least one first uplink dynamic grant; and then (through one-time screening) selecting an uplink dynamic grant meeting a first condition (the updating time is closest to the time domain resource scheduled by the target uplink configuration grant and is before the time domain resource scheduled by the target uplink configuration grant) from the at least one first uplink dynamic grant, so as to obtain a target uplink dynamic grant, and updating the target uplink configuration grant according to the target uplink dynamic grant. That is, the UE first performs twice screening on the at least one uplink dynamic grant according to the second condition to obtain a plurality of uplink dynamic grants, and then performs once screening on the plurality of uplink dynamic grants according to the first condition to obtain the target uplink dynamic grant.
It should be noted that, if the second condition is satisfied, and the uplink dynamic grant that satisfies the first condition is one, the target uplink dynamic grant may be the one uplink dynamic grant; if the number of the uplink dynamic grants meeting the first condition is more than one under the condition of meeting the second condition, the target uplink dynamic grant may be the plurality of uplink dynamic grants, and the target uplink dynamic grant may also be any one of the plurality of uplink dynamic grants.
In combination with the third possible scenario and the fifth possible scenario, the at least one second uplink dynamic grant is: at least one uplink dynamic grant (i.e. the at least one uplink dynamic grant) satisfying a first condition; wherein the first condition is: the update time is closest to the time domain resource scheduled by the target uplink configuration grant and is before the time domain resource (the time domain resource scheduled by the target uplink configuration grant).
For the description of the first condition, reference may be made to the description of the first condition in the second possible case, and details are not repeated here.
For the description of the second condition, reference may be made to the description of the second condition in the third possible case, and details are not repeated here.
It can be understood that, when the second condition is any one of the cases 1 to 3, the UE successively performs twice screening on the at least one uplink dynamic grant to obtain a target uplink dynamic grant. Taking the case 3 as an example for illustration, specifically, the UE selects an uplink dynamic grant satisfying a first condition (that is, the update time is closest to the time domain resource scheduled by the target uplink configuration grant and is before the time domain resource scheduled by the target uplink configuration grant) from the at least one first uplink dynamic grant, that is, obtains at least one second uplink dynamic grant; and then selecting an uplink dynamic grant meeting a second condition (the distance between a second frequency domain position in the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant is closest) from the at least one second uplink dynamic grant, so as to obtain a target uplink dynamic grant, and updating the target uplink configuration grant according to the target uplink dynamic grant. That is, the UE first screens the at least one uplink dynamic grant according to the first condition to obtain a plurality of uplink dynamic grants, and then screens the plurality of uplink dynamic grants according to the second condition to obtain the target uplink dynamic grant.
For example, as shown in fig. 10, the UE receives two uplink dynamic grants (i.e. the at least one first uplink dynamic grant) from the network device, namely, an uplink dynamic grant C and an uplink dynamic grant D, where an update time of the uplink dynamic grant C is the same as a distance (a first distance) between a time domain resource scheduled by the target uplink configuration grant, and an update time of the uplink dynamic grant D is the same as a distance (a second distance) between a time domain resource scheduled by the target uplink configuration grant (i.e. the first distance is the same as the second distance), and both the update time of the uplink dynamic grant C and the update time of the uplink dynamic grant D are before the time domain resource scheduled by the target uplink configuration grant (i.e. both the uplink dynamic grant C and the uplink dynamic grant D satisfy the first condition); the updating time is the ending position of n symbols after the ending position of the last symbol of the time domain resource scheduled by the uplink dynamic grant. The distance (third distance) between the starting position of the frequency domain resource scheduled by the uplink dynamic grant C and the starting position of the frequency domain resource of the target uplink configuration grant is greater than the distance (fourth distance) between the starting position of the frequency domain resource scheduled by the uplink dynamic grant D and the starting position of the frequency domain resource of the target uplink configuration grant (that is, the third distance is greater than the fourth distance).
It can be understood that, when the second condition is any one of the cases 4 to 7, the UE successively performs three screening operations on the at least one uplink dynamic grant to obtain a target uplink dynamic grant. Taking the case 4 as an example, specifically, the UE selects (through one-time screening) the uplink dynamic grant satisfying the first condition (the update time is closest to the time domain resource scheduled by the target uplink configuration grant and is before the time domain resource scheduled by the target uplink configuration grant) from the at least one first uplink dynamic grant, so as to obtain at least one first uplink dynamic grant; and then (by twice screening) selecting an uplink dynamic grant satisfying a second condition (the PRB index of the first frequency domain position in the occupied or scheduled frequency domain resource is the smallest in the uplink dynamic grants occupying or scheduled frequency domain resource with the closest distance between the second frequency domain position in the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant) (specifically, the description related to the third possible case may be referred to, and is not repeated here), that is, obtaining the target uplink dynamic grant, and updating the target uplink configuration grant according to the target uplink dynamic grant. That is, the UE first performs a first screening on the at least one uplink dynamic grant according to the first condition to obtain a plurality of uplink dynamic grants, and then performs a second screening on the plurality of uplink dynamic grants according to the second condition to obtain the target uplink dynamic grant.
For example, as shown in fig. 11, the UE receives two uplink dynamic grants (i.e., the at least one first uplink dynamic grant) from the network device, where the two uplink dynamic grants are an uplink dynamic grant E and an uplink dynamic grant F, and the update time of the uplink dynamic grant E is the same as the distance (distance 1) between the time domain resources scheduled by the target uplink configuration grant, and the update time of the uplink dynamic grant F is the same as the distance (distance 2) between the time domain resources scheduled by the target uplink configuration grant (i.e., distance 1 and distance 2 are the same), and the update time of the uplink dynamic grant E and the update time of the uplink dynamic grant F are both before the time domain resources scheduled by the target uplink configuration grant (i.e., both the uplink dynamic grant E and the uplink dynamic grant F satisfy the first condition); meanwhile, the distance (distance 3) between the starting position of the frequency domain resource scheduled by the uplink dynamic grant E and the starting position of the frequency domain resource authorized by the target uplink configuration is the same as the distance (distance 4) between the starting position of the frequency domain resource scheduled by the uplink dynamic grant F and the starting position of the frequency domain resource authorized by the target uplink configuration (namely, the distance 3 and the distance 4 are the same) (namely, both the uplink dynamic grant E and the uplink dynamic grant F satisfy the condition 1 in the above case 3); the updating time is the ending position of n symbols after the ending position of the last symbol of the time domain resource scheduled by the uplink dynamic grant. The PRB index (first PRB index) of the starting position in the frequency domain resource scheduled by the uplink dynamic grant E is greater than the PRB index (second PRB index) of the starting position in the frequency domain resource scheduled by the uplink dynamic grant F (that is, the first PRB index is greater than the second PRB index), so that the target uplink dynamic grant is the uplink dynamic grant F, and the UE modifies the parameters TPMI and SRI of the target uplink configuration grant to the parameters TPMI and SRI of the uplink dynamic grant F.
It should be noted that, if the first condition is satisfied, and the uplink dynamic grant satisfying the second condition is one, the target uplink dynamic grant may be the one uplink dynamic grant; if the number of the uplink dynamic grants meeting the second condition is more than one under the condition of meeting the first condition, the target uplink dynamic grant may be the plurality of uplink dynamic grants, and the target uplink dynamic grant may also be any one of the plurality of uplink dynamic grants.
In a sixth possible case, the target uplink dynamic grant is an uplink dynamic grant meeting a third condition; the third condition includes at least one of: a first sub-condition and a second sub-condition; the first sub-condition is: the target uplink configuration authorizes the scheduled frequency domain resource, and overlaps with the target uplink dynamic authorization occupied or scheduled frequency domain resource; the second sub-condition is: newly transmitted uplink dynamic grant, or retransmitted uplink dynamic grant.
It is understood that the above-mentioned sixth possible case includes, but is not limited to, the following 5 cases:
in case 8, the third condition is that the target uplink configures the frequency domain resource authorized to be scheduled, and the frequency domain resource occupied by or scheduled by the target uplink dynamic authorization is overlapped.
It can be understood that the target uplink dynamic grant is an uplink dynamic grant in which, in at least one uplink dynamic grant, the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant are overlapped. Specifically, the target uplink dynamic grant is an uplink dynamic grant in which the frequency domain resource occupied or scheduled in at least one uplink dynamic grant is partially or completely overlapped with the frequency domain resource scheduled by the target uplink configuration grant.
In case 9, the third condition is a newly transmitted uplink dynamic grant.
It can be understood that the target uplink dynamic grant is a newly transmitted uplink dynamic grant in the at least one uplink dynamic grant. That is, if the at least one uplink dynamic grant is a newly transmitted uplink dynamic grant, the target dynamic grant is the newly transmitted uplink dynamic grant; and if the at least one uplink dynamic authorization comprises newly transmitted uplink dynamic authorization and retransmitted uplink dynamic authorization, the target dynamic authorization is the newly transmitted uplink dynamic authorization.
For example, as shown in fig. 12, the network device configures two uplink configuration grants, namely an uplink configuration grant a and an uplink configuration grant b, in advance for the UE, where the identification information of the uplink configuration grant a is 1, and the identification information of the uplink configuration grant b is 0. The UE receives a newly transmitted uplink dynamic grant G from the network equipment, the identification information of the uplink dynamic grant is 0, the updating time is the end position of n symbols after the end position of the last symbol of the time domain resource scheduled by the newly transmitted uplink dynamic grant, therefore, the target uplink dynamic grant is the newly transmitted uplink dynamic grant G, the target uplink configuration grant is an uplink configuration grant b, and the UE modifies the parameters TPMI and SRI of the uplink configuration grant b into the parameters TPMI and SRI of the uplink dynamic grant G.
In case 10, the third condition is an uplink dynamic grant for retransmission.
It can be understood that the target uplink dynamic grant is a retransmitted uplink dynamic grant in at least one uplink dynamic grant.

In case 11, the third condition is that the uplink dynamic grant is newly transmitted, and the target uplink is configured with the frequency domain resource scheduled by the grant and overlaps with the frequency domain resource occupied or scheduled by the target uplink dynamic grant.
It can be understood that the target uplink dynamic grant is an uplink configuration grant which is newly transmitted in at least one uplink dynamic grant, and the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant have overlap. That is, if the at least one uplink dynamic grant is a newly transmitted uplink dynamic grant, the target dynamic grant is the newly transmitted uplink dynamic grant, and the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant have an overlapping uplink configuration grant; if the at least one uplink dynamic grant comprises a newly transmitted uplink dynamic grant and a retransmitted uplink dynamic grant, the target dynamic grant is the newly transmitted uplink dynamic grant, and the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant have overlapped uplink configuration grants.
In case 12, the third condition is that the uplink dynamic grant is retransmitted, and the target uplink is configured with the frequency domain resource scheduled by the grant and overlaps with the frequency domain resource occupied or scheduled by the target uplink dynamic grant.
It can be understood that the target uplink dynamic grant is an uplink configuration grant which is retransmitted in at least one uplink dynamic grant, and occupies or schedules a frequency domain resource that overlaps with a frequency domain resource scheduled by the target uplink configuration grant. That is, if the at least one uplink dynamic grant is a retransmitted uplink dynamic grant, the target dynamic grant is a retransmitted uplink dynamic grant, and the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant have an overlapping uplink configuration grant; if the at least one uplink dynamic grant comprises a newly transmitted uplink dynamic grant and a retransmitted uplink dynamic grant, the target dynamic grant is a retransmitted uplink dynamic grant, and the occupied or scheduled frequency domain resource and the frequency domain resource scheduled by the target uplink configuration grant have overlapped uplink configuration grants.

That is to say, if the at least one uplink dynamic grant is a retransmitted uplink dynamic grant, the target dynamic grant is a retransmitted uplink dynamic grant, and the ratio of the target frequency domain resource to the frequency domain resource scheduled by the target uplink configuration grant is greater than or equal to the uplink dynamic grant of the first threshold; and if the at least one uplink dynamic grant comprises a newly transmitted uplink dynamic grant and a retransmitted uplink dynamic grant, the target dynamic grant is the retransmitted uplink dynamic grant, and the ratio of the target frequency domain resource to the frequency domain resource scheduled by the target uplink configuration grant is greater than or equal to the uplink dynamic grant of the first threshold value.
