The explanation of the New air interface (New Radio, NR) Physical Sidelink Control Channel (PSCCH)/physical sidelink shared Channel (PHYSICAL SIDELINK SHARED CHANNEL, PSSCH) resource map is as follows:

the NR PSCCH/PSSCH is mapped by taking a transmission unit (slot) as a unit, the starting position of the NR PSCCH/PSSCH on the slot is a fixed position, the first symbol (symbol) before the PSCCH/PSSCH is used for automatic value-added control (Automatic Gain Control, AGC), and the information on the AGC is the information on the first symbol of the PSCCH/PSSCH.

However, in Rel-18, in order to increase the opportunity for an NR Sidelink (SL) UE to access an unlicensed band (unlicensed band), it is being considered to set the start positions of a plurality of PSCCHs/PSSCHs on a slot. Then, a corresponding AGC symbol should be set before each PSCCH/PSSCH transmission position, i.e., a plurality of AGC symbols should be set in order to improve demodulation performance.

However, as shown in fig. 2, although the introduction of multiple AGC symbols can increase the chance of a UE accessing a channel, for PSCCH/psch transmitted across multiple AGC symbols, the introduction of multiple AGC symbols can affect existing rules for mapping of SL information, and Demodulation performance of such information can be affected if the rules for mapping of SL information (e.g., side link control information (Sidelink Control Information, SCI), phase tracking reference signal (Phase-TRACKING REFERENCE SIGNAL, PT-RS), demodulation reference signal (Demodulation REFERENCE SIGNAL, DMRS), etc.) remain unchanged. Similarly, multiple AGC symbols may also affect the computation of PSCCH/PSSCH transmission parameters (e.g., TBS, CSI, etc.), and if the transmission parameters are not changed, the transmission efficiency and reliability may be affected.

The transmission method, the UE and the readable storage medium provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by some embodiments and application scenarios thereof.

Fig. 3 shows a flowchart of a transmission method according to an embodiment of the present application, as shown in fig. 3, the transmission method may include the following step 201:

step 201, the UE performs a first operation based on a first AGC symbol on a first transmission unit.

In an embodiment of the present application, the first operation includes any one of the following:

1) Performing a second operation on the first information at the first AGC symbol;

2) And calculating the transmission parameters of the first channel based on the reference resources of the first channel, wherein the reference resources of the first channel exclude the resources corresponding to the first AGC symbols on the first transmission unit.

In the embodiment of the present application, the first AGC symbol is at least one AGC symbol in the first transmission unit except for the first AGC symbol. In other words, the first transmission unit includes at least two AGC symbols, and the first AGC symbol is one or more AGC symbols of the first transmission unit except for the first AGC symbol.

In the embodiment of the present application, the first channel may include a PSCCH or a PSSCH.

In the embodiment of the present application, AGC information is mapped on the first AGC symbol.

Illustratively, the AGC information includes at least one of:

The same information as mapped on the first AGC symbol on the first transmission unit;

the same information as mapped on the symbol preceding or following the first AGC symbol;

protocol agreed or network side device configured or network side device preconfigured information.

Optionally, in an embodiment of the present application, the first information includes at least one of the following:

side link control information (Sidelink Control Information, SCI) carried by said first channel;

A Phase tracking reference signal (PT-RS) to be transmitted by the first transmission unit;

demodulation reference signal (Demodulation REFERENCE SIGNAL, DMRS).

In an example, in combination with the above step 201, in the case where the first information includes at least one of SCI and PT-RS, the process of "performing the second operation on the first information at the first AGC symbol" includes the following step 201a:

step 201a, performing rate matching or puncturing operation on the first information at the first AGC symbol.

Illustratively, the SCI is rate matched or punctured at the first AGC symbol.

Illustratively, the PT-RS is rate matched or punctured at the first AGC symbol.

In an example, in combination with the step 201, in a case where the first information includes DMRS, performing a second operation on the first information at the first AGC symbol includes step 201b:

In step 201b, when the mapping position of the DMRS on the first transmission unit overlaps with the position of the first AGC symbol, the UE adjusts the mapping position of the DMRS on the first transmission unit according to the first rule.

Illustratively, the mapping position of the adjusted DMRS on the first transmission unit does not overlap with the position of the first AGC symbol.

Further exemplary, the first rule includes at least one of:

Mapping the DMRS to a first symbol;

and excluding the first AGC symbol in the mapping process of the DMRS, and mapping the DMRS to a second symbol.

Illustratively, the first symbol and the second symbol are both non-AGC symbols on the first transmission unit described above.

Illustratively, the first symbol may be a preceding or a following one of the first AGC symbols.

Illustratively, the first AGC symbol is excluded from the DMRS mapping process, in other words, after the position of the first AGC symbol is ignored in the mapping process, the DMRS is mapped to the second symbol according to the DMRS mapping rule.

In this way, the impact of the first AGC symbol on the information carried on the channel and the mapping of the transmission information transmitted on the same transmission unit can be reduced.

Optionally, in the embodiment of the present application, the transmission method provided in the embodiment of the present application further includes the following step 301:

step 301, determining whether to map the first AGC information on the first transmission unit based on the first condition.

Illustratively, the first condition includes at least one of:

Condition 1: whether the number of frequency domain resources occupied by the first channel transmission meets a second condition or not;

condition 2: whether the setting of the frequency domain resources in the resource pool meets the preset setting;

condition 3: whether reserved resources of other UE exist on the time domain resources of the first channel occupied by the UE;

condition 4: whether the transmission parameters of the first channel used by the UE meet the third condition.

Illustratively, the first AGC information is information mapped on a second AGC symbol on the first transmission unit.

Illustratively, the UE maps the first AGC information to the target symbol in the first transmission unit by determining whether the target symbol satisfies the first condition. It will be appreciated that the target symbol is any symbol other than the first AGC symbol on the first transmission unit described above, and when the first AGC information is mapped to the target symbol, the target symbol is referred to as a first AGC symbol.

Illustratively, for condition 1 above, the second condition includes at least one of:

the number of sub-channels in the frequency domain resource occupied by the first channel transmission is greater than or equal to the number of preset sub-channels;

The ratio of the frequency domain resource occupied by the first channel transmission in the target resource is larger than the preset frequency domain resource ratio;

the frequency domain resource occupied by the first channel transmission is a target resource.

Illustratively, the target Resource may be an entire Resource pool or an entire Bandwidth Part (BWP) or an entire Resource block set (RB set).

Illustratively, when the number of occupied frequency domain resources of the first channel satisfies the second condition, the first AGC information is not mapped in the symbol on the first transmission unit; otherwise, the first AGC information is mapped.

For example, if the number of sub-channels in the frequency domain resource occupied by PSCCH or PSSCH transmission is greater than or equal to the preset number of sub-channels, or the duty ratio of the frequency domain resource occupied by PSCCH or PSSCH transmission in the frequency domain resource occupied by PSCCH or PSSCH transmission is greater than the preset frequency domain resource duty ratio, or the frequency domain resource occupied by PSCCH or PSSCH transmission is the target resource, the UE does not need to map the first AGC information in the symbol of the first transmission unit; otherwise, the first AGC information is mapped.

For example, for the condition 2, the predetermined setting may be agreed upon or configured or preconfigured by the network side device.

Illustratively, when the setting of the frequency domain resources in the resource pool satisfies the predetermined setting, the first AGC information is not mapped in the symbol on the first transmission unit; otherwise, the first AGC information is mapped.

For example, if there is only one subchannel in the resource pool or in the RB set, or the resource pool setting allows only time division multiplexing (Time division multiplexing, TDM) between UEs, the UE does not need to map the first AGC information in the symbol of the first transmission unit; otherwise, the first AGC information is mapped.

Illustratively, for the above condition 3, before n transmission units of PSCCH or PSSCH transmission, the UE detects that the resources reserved by other UEs are also on the time domain resources used by the PSCCH or PSSCH, and/or that the transmission start position of the PSCCH or PSSCH of another UE is inconsistent with the UE. For example, the PSCCH or PSSCH of the UE starts transmission from symbol #0, and the PSCCH or PSSCH of the other UE starts transmission from symbol # 7. At this time, the UE needs to map the first AGC information in the symbol of the first transmission unit; otherwise, the first AGC information is not mapped.

Illustratively, for condition 4 above, the third condition includes at least one of:

the modulation and coding scheme (Modulation and coding scheme, MCS) used is greater than or equal to a preset value;

The UE uses a preset MCS table.

Illustratively, when the transmission parameter of the first channel used by the UE satisfies the third condition, mapping first AGC information in a symbol on the first transmission unit; otherwise, the first AGC information is not mapped.

For example, the AGC accuracy requirement is relatively low due to low MCS transmissions. Therefore, if PSCCH or PSSCH transmission is used to be greater than or equal to a preset value, or the UE uses a certain preset MCS table, the UE needs to map the first AGC information in the symbol of the first transmission unit; otherwise, the first AGC information is not mapped.

In one example, the UE may always map the first AGC information on the first transmission unit according to a protocol agreed or network side device configured or preconfigured indication.

In another example, the UE may autonomously decide whether to map the first AGC information in the symbols on the first transmission unit.

In this manner, it may be decided by a predetermined condition to map AGC information in symbols of the first transmission unit such that a plurality of AGC symbols exist on the first transmission unit.

Optionally, in the embodiment of the present application, after determining whether to map the first AGC information on the first transmission unit in step 301", the transmission method provided in the embodiment of the present application further includes the following step 401:

step 401, transmitting second information when the UE transmits data using the first transmission unit.

Illustratively, the second information is used to indicate whether the UE maps the first AGC information on the first transmission unit.

The second information may be transmitted in the form of SCI information.

In one example, the second information may also be used to indicate a valid first channel symbol number.

Therefore, the network side equipment UE can be informed of whether the AGC information is mapped or not through the second information, and the network side equipment can adjust according to whether the AGC information is mapped on the symbols of the transmission unit or not.

In the transmission method provided by the embodiment of the application, the UE executes a first operation based on a first AGC symbol on a first transmission unit; wherein the first operation comprises any one of: performing a second operation on the first information at the first AGC symbol; calculating a transmission parameter of a first channel based on a reference resource of the first channel, wherein the reference resource of the first channel excludes a resource corresponding to a first AGC symbol on the first transmission unit; wherein the first AGC symbol is at least one AGC symbol in the first transmission unit except the first AGC symbol. In this way, the information to be transmitted on the first transmission unit can be processed at the first AGC symbol, and the mapping rule of the information to be transmitted currently is changed, so that the influence of the first AGC symbol on the demodulation of the information to be transmitted is reduced; in addition, when the transmission parameters of the reference resources of the first channel are calculated, the resources corresponding to the first AGC symbols on the first transmission unit in the reference resources are eliminated, so that the influence of inaccurate calculated transmission parameters is reduced, and the transmission efficiency and reliability of the transmission information are improved.

Optionally, in an embodiment of the present application, in combination with the step 201, calculating the transmission parameter of the first channel includes: in the case of calculating the transport block set (Transport Block set, TBS) of the first channel, the transmission method provided in the embodiment of the present application includes the following steps 501:

Step 501, excluding resources corresponding to the first AGC symbol on the first transmission unit according to any one of the following manners:

The protocol is agreed to be such that,

The network side equipment indicates whether to exclude resources corresponding to the first AGC symbol;

the UE autonomously determines whether to exclude resources corresponding to the first AGC symbol.

Illustratively, the resources corresponding to the first AGC symbol may be equal to the resources occupied by the first AGC symbol, or the resources derived based on the resources occupied by the first AGC symbol.

Illustratively, the UE excludes resources of C symbols corresponding to the first AGC symbol in the first channel reference resource when calculating the first channel TBS.

Illustratively, the value of C described above is associated with at least one of:

the number of additional AGC symbols divided by the first AGC symbol;

Whether the first AGC symbol can be transmitted in the same transmission unit as the physical sidelink Feedback Channel (PHYSICAL SIDELINK Feedback Channel, PSFCH);

whether or not PSFCH is configured;

PSFCH cycles.

Note that the value of C may be 1,0.75,0.5. For example, if 1 additional AGC symbol is allowed in the resource pool, this additional AGC symbol cannot occur in PSFCH occasions, when PSFCH is not configured, the value of C is 1, when PSFCH is 2, the value of C is 0.5, when PSFCH is 4, the value of C is 0.75.

Optionally, in an embodiment of the present application, in combination with the step 201, calculating the transmission parameter of the first channel includes: in the case of calculating the Channel State Information (CSI) resource of the first channel, the transmission method provided in the embodiment of the present application includes the following step 601:

Step 601, excluding resources corresponding to the first AGC symbol on the first transmission unit according to any one of the following manners:

The protocol is agreed to be such that,

Illustratively, the CSI resources described above are used to feed back CSI.

For example, the UE may autonomously determine whether to exclude the first AGC symbol based on whether the first AGC information is mapped on CSI reference signal (CSI REFERENCE SIGNAL, CSI-RS) transmission resources.

Optionally, in the embodiment of the present application, the available reference resource of the second stage SCI (2 ^nd stage SCI) of the first channel is calculated.

Illustratively, the above SCI may use the reference resource calculation process to exclude resources of C symbols corresponding to the first AGC symbol.

Thus, the influence of a plurality of AGC symbols when the UE calculates channel transmission parameters can be reduced, and the transmission efficiency of the transmission data is improved.

Optionally, in the embodiment of the present application, after "excluding the resource corresponding to the first AGC symbol on the first transmission unit" in the step 401, the step 501, and the step 601, the transmission method provided in the embodiment of the present application includes the following step 701:

Step 701, transmitting third information when the UE transmits data using the first transmission unit.

Illustratively, the third information is used to indicate whether the UE excludes the resource corresponding to the first AGC symbol on the first transmission unit.

In this way, the indication information informs the network side device whether the UE excludes the first AGC symbol on the first transmission unit, so that the network side device can restore the excluded AGC symbol according to the indication information.

In the related art, there is no scheme for determining the contention window size according to the transmission states of channels corresponding to the multiple propagation types in the case where the multiple propagation types exist in the reference time period. . The transmission method provided by the embodiment of the application can solve the problem that the UE determines the size of the contention window according to the transmission state of the channel corresponding to the multiple propagation types under the condition that the multiple propagation types exist in the reference time period.

Fig. 4 shows a flowchart of a transmission method according to an embodiment of the present application, as shown in fig. 4, where the transmission method may include the following step a:

and step A, under the condition that N propagation types exist in the reference time period, the UE determines the size of the contention window based on the transmission states of N second channels corresponding to the N propagation types. Wherein N is a positive integer greater than 1.

Illustratively, the N propagation types described above may include any of the following: unicast (Unicast) sidelink hybrid automatic repeat request (sidelink Hybrid Automatic Repeat reQuest, SL-HARQ) enabled (enabled), multicast mode 1 (groupcast option 1), multicast mode 2 (groupcast option 2), SL-HARQ disabled (disabled).

Optionally, in the embodiment of the present application, the step a "the UE determines the contention window size" based on the transmission states of the N second channels corresponding to the N propagation types may be implemented by the following step A1 and/or step A2:

And A1, determining the size of a contention window based on the transmission state of a third channel corresponding to the first propagation type with the highest priority among the N propagation types.

Illustratively, the third channel is one of the N second channels.

Illustratively, the priority of the N propagation types may be determined based on the accuracy of the hybrid automatic repeat request acknowledgement (Hybrid Automatic Repeat request-ACKnowledgement, HARQ-ACK) feedback.

Illustratively, the prioritization of the N propagation types is as follows: unicast SL-HARQ enabled > groupcast option 2>groupcast option 1>SL-HARQ disabled.

Illustratively, the UE selects a highest priority propagation type (e.g., unicast SL-HARQ enabled) among the N propagation types, and determines the contention window size according to the transmission state of the third channel corresponding to the propagation type.

And A2, determining the size of the contention window according to the transmission state of the fourth channel in the transmission sequence of the N second channels.

Illustratively, the fourth channel is one of the N second channels.

The contention window size is determined according to the fourth channel in the order of transmission of the N second channels, or according to the transmission status of the fourth channel in the order of PSFCH corresponding to the N second channels.

The fourth channel may be the first channel, the last channel, or a channel in a predetermined order among the N second channels.

In the transmission method provided by the embodiment of the application, under the condition that N propagation types exist in the reference time period, the UE determines the size of the contention window based on the transmission states of N second channels corresponding to the N propagation types. In this way, the contention window size may be determined in the case where there are a plurality of propagation types in the reference period.
