[0034] The technical solutions provided by the embodiments of the present application will be described in detail below in combination with the drawings and some embodiments and application scenarios.

[0035] As shown in FIG. 2, a flowchart of a transmission method 200 provided by an exemplary embodiment of the present application is shown, which can be executed by a terminal, but is not limited thereto, and can be executed by at least one of hardware and software installed in the terminal. In the embodiment, the method 200 can at least include the following steps.

[0036] S210, the terminal determines target configuration information from N first configuration information.

[0037] The first configuration information can also be referred to as scheduling configuration information, etc., which is used to configure all transmission parameters when scheduling channels such as a physical uplink shared channel (PUSCH), a physical downlink shared channel (PDSCH), etc.

[0038] It is worth noting that, relative to the problem of large scheduling signaling overhead that can occur in the related art when dynamic scheduling is used, such as the transmission amount of control signaling being greater than the transmission amount of data services. In the present embodiment, the terminal is configured with N pieces of first configuration information through protocol agreement or high-layer semi-static configuration, thereby reducing the transmission amount of control signaling in the data transmission process, that is, reducing the overhead of control signaling.

[0039] In addition, in the present embodiment, N is an integer greater than or equal to 1, that is, one or more sets of transmission parameters for channel scheduling can be configured in the present embodiment, thereby adapting to the scheduling of data packets of different data amounts, different transmission periods, and even time-irregular services, thereby improving the resource utilization rate during channel (or service) scheduling transmission and avoiding resource waste problems. Especially for the scheduling of time-irregular service packets such as Haptic services.

[0040] In some embodiments, the number or maximum number of the first configuration information can be agreed by the protocol or configured by the network side, which is not limited herein.

[0041] S220, performing target channel transmission according to the target configuration information.

[0042] The target configuration information is used to configure transmission parameters for scheduling target channel transmission. Optionally, the target channel can include but is not limited to one or more of PUSCH, PDSCH, etc.

[0043] In some embodiments, the transmission parameters can include but are not limited to one or more of time domain resource allocation parameters, frequency domain resource allocation parameters, modulation and coding scheme (MCS), demodulation reference signal (DMRS) mode, multiple-input multiple-output (MIMO) layer number, etc.

[0044] The time domain resource allocation parameter can include but is not limited to one or more of the length of the time domain resource, the starting position of the time domain resource, the ending position of the time domain resource, the variation of the time domain resource, etc.

[0045] The start position or the end position of the time domain resource can be an absolute time position, or an offset relative to a receiving time corresponding to scheduling signaling (such as a physical downlink control channel (PDCCH), downlink control information (DCI), or the like), and the like.

[0046] The change amount of the time domain resource can be an increase amount or a decrease amount of the time domain resource relative to a reference time domain resource, or an increase amount or a decrease amount relative to a last scheduled time domain resource. In this way, by configuring the change amount of the time domain resource, the overhead in time domain resource configuration can be reduced.

[0047] In the embodiment, the time domain resource allocation parameter can be configured based on a basic time unit (such as a symbol, a slot, or the like) defined by a physical layer, but is not limited thereto. The reference subcarrier spacing (SCS) of the basic time unit can also be configured or determined based on an active time domain resource or a frequency domain resource. The frequency domain resource can be an active bandwidth part (BWP), an active carrier, or the like, but is not limited thereto.

[0048] In some embodiments, for a case where the first configuration information is configured semi-statically by a higher layer, the time domain resource allocation parameter can indicate one or more time domain resources. For a case where multiple time domain resources are indicated, multiple independent indication fields can be used to respectively indicate each time domain resource, or a bitmap can be used to indicate multiple time domain resources, and the like. The number of the multiple time domain resources can also be indicated by a specific indication field.

[0049] The frequency domain resource allocation parameter includes one or more of a size of the frequency domain resource, a start position of the frequency domain resource, an end position of the frequency domain resource, a mapping position of the frequency domain resource, a change amount of the frequency domain resource, and the like.

[0050] The change amount of the frequency domain resource can be an increase amount or a decrease amount of the frequency domain resource relative to a reference frequency domain resource, or an increase amount or a decrease amount relative to a last scheduled frequency domain resource. In this way, by configuring the change amount of the frequency domain resource, the resource overhead in frequency domain resource configuration can be reduced.

[0051] In some embodiments, for the case of configuring multiple first configuration information, the network side device can send a first indication information to the terminal to indicate the effective (or activated) first configuration information, i.e., the target configuration information, thereby implicitly informing the terminal of the transmission parameters for scheduling physical channels such as PUSCH and PDSCH, thereby achieving the scheduling of physical channels such as PUSCH and PDSCH.

[0052] In this case, for the terminal, the terminal can receive a first indication information from the network side device, the first indication information being used to indicate that at least one of the N first configuration information is effective, so that the terminal can determine the target configuration information from the effective first configuration information to perform transmission of the target channel.

[0053] In some embodiments, the first indication information can be, but is not limited to, PDCCH, DCI, etc. It can include at least one of identification information and bitmap information. The identification information is used to identify the effective first configuration information. That is, as shown in Table 1, in this embodiment, an identification (or index) can be configured for each first configuration information to identify the effective first configuration information indicated by the network side device to the terminal, so as to achieve the scheduling of target channels such as PDSCH and PUSCH, while avoiding the problem of large signaling overhead caused by carrying part or all of the scheduling configuration information in the scheduling signaling in the related art.

[0054] Table 1

[0055] The bitmap information is used to indicate the effective first configuration information. That is, the first indication information can include a bitmap field, each bit in the bitmap field corresponding to the identification of a first configuration information to indicate the effectiveness (or activation) / invalidity (deactivation) of the first configuration information. Based on this, the network side device sets the bitmap field to indicate at least one of the effective or ineffective first configuration information to the terminal, so as to achieve the scheduling of target channels such as PDSCH and PUSCH, while avoiding the problem of large signaling overhead caused by carrying part or all of the scheduling configuration information in the scheduling signaling in the related art.

[0056] In some embodiments, in addition to the aforementioned indication of the effective first configuration information by the network side device to achieve the scheduling of physical channels such as PUSCH and PDSCH, the terminal can also send a second indication information to the network side device to request or indicate at least one of the N first configuration information that the terminal wants to activate or expects to activate, thereby assisting the network side device in scheduling physical channels such as PUSCH and PDSCH.

[0057] Optionally, similar to the first indication information, the second indication information can also include, but is not limited to, at least one of the identification information and the bitmap information. The identification information is used to identify the first configuration information that the terminal validates or requests or expects. The bitmap information is used to indicate the first configuration information that the terminal validates or requests to validate or expects to validate. It can be understood that the identification information and the bitmap information can refer to the related description of the first indication information, and details are not repeated here.

[0058] Correspondingly, after receiving the second indication information, the network side device can default the second indication information to indicate the first configuration information that is validated or requested to validate or expected to validate, which is used for scheduling of physical channels such as PUSCH, PDSCH, etc. The network side device can also determine the validated first configuration information according to the second indication information. If the terminal indicates the first configuration information that is expected to validate through the second information, the network side device can determine the validated first configuration information after receiving the second indication information, and the determined validated first configuration information can also be indicated to the terminal. Or, if the terminal indicates the first configuration information that has been validated through the second information, the network side device can determine which first configuration information has been validated after receiving the second indication information, and the further behavior of the network side device is not limited here.

[0059] Exemplarily, after the network side device indicates N first configuration information to the terminal, the terminal can apply uplink transmission resources to the network side device through the second indication information, or the terminal can also apply transmission parameters associated with the uplink transmission resources through the second indication information, and the network side device determines the scheduling information for the terminal based on the application. The second indication information can be carried by one or more of, but is not limited to, scheduling request (SR), buffer status report (BSR), etc.

[0060] Exemplarily, after the network-side device indicates N first configuration information to the terminal, the terminal can autonomously select a certain first configuration information for PUSCH transmission, and indicate the selected first configuration information to the network-side device through second indication information (for example, the second information is carried by PUCCH, PUSCH, etc.), and the network-side device determines the first configuration information used by the terminal based on the application, and gives up which first configuration information, and the further behavior of the network-side device is not limited here. Wherein, the second indication information can be carried by one or more of physical uplink control channel (Physical Uplink Control Channel, PUCCH), uplink control information (Uplink Control Information, UCI), PUSCH, etc.

[0061] That is, in the embodiment, the second indication information can be, but is not limited to, one or more of SR, BSR, UCI, PUCCH, and other uplink control signaling.

[0062] It is worth noting that for the foregoing first indication information and the second indication information, if the indicated or requested first configuration information is one, the terminal can determine the indicated or requested first configuration information as the target configuration information; if the indicated or requested first configuration information is multiple, the terminal can select one from them as the target configuration information according to the protocol agreement, high-layer configuration, etc.

[0063] Optionally, if the terminal selects one from multiple effective first configuration information as the target configuration information on demand, the network-side device can be indicated again to ensure that the terminal and the network-side device understand the target configuration information consistently.

[0064] In some embodiments, for the foregoing N first configuration information, before using the first configuration information, the second configuration information, or indicating or requesting the first configuration information, M second configuration information in a pre-effect state (or pre-activation state) can also be configured when configuring the N first configuration information, or the M second configuration information in the pre-effect state can also be indicated by DCI, medium access control control element (Medium Access Control Control Element, MAC CE), etc. signaling in the N first configuration information, that is, the second configuration information. Thus, when the first configuration information or the second configuration information is used to indicate or request the first configuration information, the M second configuration information in the pre-effect state can be implemented to reduce the resource overhead of indicating or requesting the first configuration information. Wherein, M is an integer greater than or equal to 1.

[0065] That is, the first indication information indicating the effective first configuration information can be determined based on the M second configuration information, thereby reducing resource overhead of the network side device indicating the effective first configuration information to the terminal. Similarly, the second indication information indicating or requesting the effective first configuration information can also be determined based on the M second configuration information, thereby reducing resource overhead of the terminal indicating or requesting the effective first configuration information to the network side device.

[0066] In some embodiments, the network side device can further send fourth indication information to the terminal for updating at least one or more of the N first configuration information. Correspondingly, the terminal receives the fourth indication information from the network side device and updates the first configuration information according to the fourth indication information. Thus, the updated first configuration information matches the scheduling requirements of the network side device, such as matching the size of the scheduled data packet, avoiding resource waste.

[0067] Optionally, the fourth indication information can carry the identification of the first configuration information that needs to be updated and the updated configuration information, so that the terminal is clear about which first configuration information needs to be updated, improving information update efficiency. The fourth indication information can be carried by dynamic signaling such as MAC CE, DCI, etc.

[0068] In some embodiments, the first indication information or the second indication information described above can be of sequence type. That is, this embodiment provides a sequence type of first indication information from the perspective of physical layer (PHY) scheduling signaling design, and a sequence type of second indication information from the perspective of physical layer resource request signaling design, for indicating or requesting at least one of the N first configuration information to be effective. Thus, by taking advantage of the characteristic of sequence having fewer bits, resource overhead during information indication is reduced, and terminal complexity during indication information processing is reduced.

[0069] Optionally, the type of the sequence can be predetermined by a protocol or configured by the network side. For example, in this embodiment, the sequence can be, but is not limited to, a ZC (Zadoff-Chu) sequence, a Walsh sequence, a maximum linear feedback shift register sequence (M sequence), a Gold sequence, etc.

[0070] Based on this, if the first configuration information is one, the sequence type of first indication information can be used to indicate whether the first configuration information is effective, or if the first configuration information is multiple, the sequence type of first indication information can be used to indicate which one of the multiple first configuration information is effective, so as to realize scheduling transmission such as PDSCH, PUSCH, etc.

[0071] In some embodiments, the network-side device can send third configuration information to the terminal, and the terminal can receive the third configuration information from the network-side device; wherein the third configuration information is used to configure at least one sequence set and related information of the sequence set, so that the terminal can receive the first indication information and determine which first configuration information is valid according to the third configuration information.

[0072] Alternatively, the terminal can send the second indication information according to the third configuration information, such as determining which sequence to use to indicate the valid or requested first configuration information.

[0073] In this embodiment, one sequence set can include at least one sequence. Wherein the length of one sequence, the size of the mapped time-frequency resource, etc. can be agreed by the protocol or configured by the upper layer, for example, the length of the sequence can be 12 or 24, etc. Each sequence can occupy X time units and Y frequency domain units, wherein X and Y are both integers greater than or equal to 1.

[0074] Based on this, in some embodiments, the related information of the sequence set can include but is not limited to at least one of 11)-15).

[0075] 11) The corresponding relationship or mapping relationship between each sequence in the sequence set and N first configuration information.

[0076] Wherein, the corresponding relationship or mapping relationship can be one sequence corresponding to one first configuration information, multiple sequences corresponding to one first configuration information, one sequence corresponding to multiple first configuration information, etc.

[0077] Based on this, for the first indication information, the corresponding relationship or mapping relationship can be used by the terminal to determine which first configuration information is valid for the received sequence type first indication information. For example, assuming that a sequence A has a corresponding relationship with a first configuration information B, when the first terminal determines that the received first indication information is sequence A, it can be determined that the valid first configuration information is the first configuration information B with the corresponding relationship.

[0078] Similarly, for the second indication information, after determining the valid or expected valid first configuration information, the terminal can select a sequence corresponding to the first configuration information as the second indication information according to the corresponding relationship or mapping relationship, to indicate or request the validity of the first configuration information.

[0079] 12) The time-frequency resource information corresponding to each sequence in the sequence set.

[0080] The time-frequency resource information can be time-domain resource information, time-domain resource start information, time-domain resource end information, time-domain resource length, frequency-domain resource information, frequency-domain resource start information, frequency-domain resource end information, time-domain resource length, etc., corresponding to a sequence, for sending the second indication information of the sequence type, etc.

[0081] 13) Search space, used for monitoring or blind detection of each sequence in the sequence set. The search space may map to the time-frequency resource set of the first indication information, and may include, but is not limited to, the length of the time-domain resource, the start position of the time-domain resource, the period, and the size of the frequency-domain resource.

[0082] In some embodiments, the frequency domain resources corresponding to the search space can be greater than the frequency domain resources required for each sequence, so as to avoid the possibility that the terminal may miss the first indication information of the sequence type in the search space.

[0083] Optionally, the sequence can be distributed or centralized on the time-frequency resource set corresponding to the search space, without any limitation.

[0084] 14) The aggregation level (AL) of each sequence in the sequence set.

[0085] In order to adapt to the channel environment and sequence length, a sequence can be composed of multiple control channel elements (CCEs). The number of CCEs mapped to a sequence can be the aggregation level of a sequence, such as 1, 2, 4, 8, 16, etc.

[0086] 15) The blind decoding budget (BD budget) for each sequence in the sequence set.

[0087] The blind detection budget can be set independently, such as through pre-definition or network-side configuration.

[0088] In some embodiments, when the network-side device configures or instructs a terminal to a set of multiple sequences, the set of sequences may, but is not limited to, satisfy at least one of the following 21)-24).

[0089] 21) The length of each sequence in different sets of sequences is set independently.

[0090] Optionally, the lengths of the sequences in different sequence sets can be different, such as the length of a sequence being an integer multiple of the length of a reference sequence, in which case the time-frequency resources mapped by the sequence can also be an integer multiple of the time-frequency resources occupied by the reference sequence.

[0091] 22) The aggregation levels associated with different sequence sets are independently set.

[0092] Optionally, the aggregation levels associated with different sequence sets can be different.

[0093] 23) In the case of ZC sequences, the first parameters (such as U and V parameters) corresponding to different sequences in the same sequence set are the same, and the first parameters are the base sequences used to generate the sequences. That is, for ZC sequences, different sequences in the same sequence set can be generated based on the same base sequence.

[0094] 24) In the case of ZC sequences, the cyclic shift (CS) values corresponding to two adjacent sequences in the same sequence set have the same interval. It can be understood that the sequences in the same sequence set are sorted according to the size of the CS values.

[0095] In some embodiments, the terminal can also support repetition transmission of the sequence, such as repetition transmission in the time domain or frequency domain, to achieve the purpose of coverage enhancement. Based on this, the repetition number of the repetition transmission corresponding to a sequence can satisfy at least one of 31)-33).

[0096] 31) The repetition number is related to the aggregation level of the sequence. For example, for the same sequence, the repetition number of the sequence is less than or equal to the aggregation level of the sequence, etc.

[0097] 33) The repetition number is configured in the related parameters of the search space.

[0098] 33) The repetition number is the same as the number of time domain basic units corresponding to the search space. That is, the repetition number can be implicitly equivalent to the number of time domain basic unit lengths in the search space.

[0099] In some embodiments, in the case where the target channel is a multi-layer transmission and the target indication information is a multi-layer transmission, each layer of the target indication information corresponds to each layer of the target channel one by one to control each layer of the channel, such as a PDSCH, etc. The target indication information is the first indication information or the second indication information.

[0100] In the embodiment, the layer of the first indication information or the second indication information transmission can be single layer, so that the reliability of the indication information transmission can be improved.
