Description

Technical Field

[0001] This application relates to, but is not limited to, the field of communications. Specifically, it relates to an information transmission method and apparatus. Background Art

[0002] For the in-band bandwidth coexistence between the synchronization signals / channels of Long-Term Evolution Vehicle-to-Everything (LTE V2X) and New Radio Vehicle-to-Everything (NR V2X) (between SLSS / PSBCH and S-SSB), where the Sidelink Synchronisation Signal (SLSS for short), Physical Sidelink Broadcast Channel (PSBCH for short), and S-SSB includes S-PSS (Sidelink Primary Synchronization Signal) and / or S-SSS (Sidelink Secondary Synchronization Signal) and / or PSBCH. The overlap between the resources of SLSS / PSBCH and S-SSB can be avoided through semi-static configuration / pre-configuration. Since the period of LTE V2X synchronization resources is fixed (160 ms), and the period of NR V2X synchronization resources has not yet been finalized, a solution needs to be considered to address the resource conflict between the two.

[0003] For the sidelink synchronization signal / channel and the traffic channel, since the duration of the sidelink resource pool in the time domain is relatively long and the configuration methods are also different. For example, the available resources of the sidelink resource pool can be configured in the form of a bitmap. Therefore, the configured sidelink resource pool may overlap with the synchronization resources of other Radio Access Technologies (RATs) in the time domain.

[0004] In this case, it is necessary to consider the signal / channel transmission problem when there is resource overlap between the sidelink synchronization signal / channel of different Radio Access Technologies (RATs) (LTE and NR) and the traffic channel.

[0005] On the other hand, the synchronization resources of NR V2X may also overlap with the resources of the uplink (UL) transmission of the cellular system (on the same carrier or different carriers), and the transmission problem of the sidelink synchronization signal / channel and the traffic channel also needs to be considered.

[0006] In New Radio Vehicle-to-Everything (NR V2X), the NR V2X module and the LTE V2X module may coexist in a User Equipment (UE) simultaneously. NR V2X and LTE V2X operate on different carriers within the same band (in-band). The resources used for sidelink communication (transmission / reception) by two Radio Access Technologies (RATs) on different carriers may overlap in the time domain. Due to the UE radio frequency capabilities and half-duplex limitations, the UE cannot simultaneously transmit sidelink signals on two carriers within the same band, or transmit and receive simultaneously (simultaneous reception on two carriers can be achieved by the UE). Therefore, it is necessary to consider how to transmit the NR V2X and LTE V2X signals / channels when the resources on the two carriers overlap.

[0007] The in-device coexistence problem of the traffic channels of LTE V2X and NR V2X is a currently under-researched issue. There is still no complete solution to the problem of how to transmit / receive traffic channels when the resources on the two carriers overlap. In particular, there is no relevant proposal discussion on how to transmit the synchronization channel or traffic channel when the resources of the sidelink synchronization signal / channel overlap with the sidelink resources (synchronization resources or traffic channel resources) on another carrier.

[0008] Regarding the transmission conflict problem when the transmissions of different RATs overlap in the time domain in the case of in-device coexistence in related technologies, there is currently no effective solution. Summary of the Invention

[0069] The following is described in conjunction with another embodiment of the present application.

[0070] Scenario assumption: LTE V2X and NR V2X coexist in the same UE and operate on different carriers of the same band. When the sidelink synchronization resources of one RAT overlap with the resources of the traffic channel of another RAT, the following transmission schemes are available according to different transmission and reception situations:

[0071] Scheme 1) Indicate the transmission / reception priority of the synchronization signal / channel:

[0072] If the resources for transmitting the traffic channel (such as the Physical Sidelink Shared Channel, PSSCH) overlap with the sidelink synchronization resources, compare the priorities of the traffic channel and the sidelink synchronization signal / channel.

[0073] Among them, the sidelink synchronization resources can be used for transmitting the sidelink synchronization signal / channel or for receiving the sidelink synchronization signal / channel.

[0074] The priority of the sidelink synchronization signal / channel is determined by predefined, configured or preconfigured means.

[0075] For the priority of the sidelink synchronization signal / channel, it includes at least one of the following: the sidelink synchronization signal / channel is fixed to a single priority (i.e., the sidelink synchronization signal / channel has only one priority); the priorities corresponding to different synchronization reference sources are different (i.e., the sidelink synchronization signal / channel has multiple priorities, and different synchronization reference sources result in different priorities); the levels relative to the highest-level synchronization source (base station, GNSS or UE) are different (such as directly synchronized to GNSS and indirectly synchronized to GNSS), and the corresponding priorities of the sidelink synchronization signal / channel are different; the priorities of the sidelink synchronization signals / channels of different RATs (such as the synchronization signal / channel of NR V2X and the synchronization signal / channel of LTE V2X) are different.

[0076] The value of the priority of the sidelink synchronization signal / channel is not greater than the maximum value of the priority of the sidelink traffic channel (PSSCH (Physical Sidelink Shared Channel) of NR V2X or LTE V2X, taking the PSSCH with the higher priority), and at the same time not less than the minimum value of the priority of the sidelink traffic channel.

[0077] Compare the priorities of the traffic channel and the sidelink synchronization signal / channel, including: if the priority of the traffic channel is higher than that of the sidelink synchronization signal / channel, send the traffic channel and / or do not send (drop) the sidelink synchronization signal / channel; if the priority of the traffic channel is not higher than that of the sidelink synchronization signal / channel, send the sidelink synchronization signal / channel and / or do not send (drop) the traffic channel.

[0078] Among them, the traffic channel and the sidelink synchronization signal / channel can be on the same carrier or on different carriers.

[0079] Solution 2) Configure a priority threshold to compare priorities with the traffic channel:

[0080] Configure or pre-configure a decision threshold A. When the traffic channel is sent, if the transmission resources overlap with the sidelink synchronization resources, compare the priority of the traffic channel with the decision threshold A, including: if the priority of the traffic channel is higher than the decision threshold A, send the traffic channel and / or do not send (drop) the sidelink synchronization signal / channel; otherwise, send the sidelink synchronization signal / channel and / or do not send (drop) the traffic channel.

[0081] Among them, the traffic channel and the sidelink synchronization signal / channel can be on the same carrier or on different carriers.

[0082] Solution 3) In LTE, 8 logical channel priority values are defined as {1, 2, 3, 4, 5, 6, 7, 8}, and in NR, 16 logical channel priority values are defined as {1, 2, 3,... 15, 16}. For the synchronization signal / channel SLSS / PSBCH of LTE V2X, the priority P1 is a value between 1 and 8, and for the synchronization signal / channel S-SSB of NR V2X, the priority P2 is a value between 1 and 16. Since the number of priority levels between LTE V2X and NR V2X is not equal, a mapping relationship needs to be established between them (the LTE V2X priority value and the NR V2X priority value), including: one-to-one mapping based on the priority value, mapping 1 to 8 to 1 to 8, and the priority values 9 to 16 of NR V2X are directly determined to be less than the priority value 8 in LTE V2X; one-to-one mapping based on the priority value, mapping the priority values 9 to 16 of NR V2X to the priority values 1 to 8 of LTE V2X, and the priority values 1 to 8 of NR V2X are directly determined to be higher than the priority value 1 in LTE V2X; the priority values 1 and 2 of NR V2X are mapped to the priority value 1 of LTE V2X. In the same way, 3 and 4 are mapped to 2, and so on, 15 and 16 are mapped to 8. That is, the priority values 2n - 1 and 2n of NR V2X are mapped to the priority value n of LTE V2X, where n is a positive integer from 1 to 8.

[0083] Solution 4) The transmission or reception priority of the sidelink synchronization signal / channel can be fixed to be higher than that of the traffic channel, that is, by default, the sidelink synchronization signal / channel is preferentially transmitted or received. For the transmission and reception priorities of the sidelink synchronization signal / channel, they can be set differently. One way is to ensure that transmitting the sidelink synchronization signal / channel enables other nearby UEs to quickly obtain synchronization, and thus increase the transmission priority of the sidelink synchronization signal / channel. For example, map the transmission priority of the sidelink synchronization signal / channel to be 2 higher than the reception priority of the sidelink synchronization signal / channel, and at the same time not exceed the maximum priority value.

[0084] Solution 5) The sidelink synchronization signal / channel described above includes at least one of the following: S-SSB, SLSS (PSSS or SSSS), PSBCH.

[0085] Solution 6): For the reception of sidelink synchronization signals / channels, if the reception resources overlap with the transmission resources of the sidelink traffic channel, when the UE receives (detects) the synchronization signals / channels in the overlapping resources, compare the priorities of the sidelink synchronization signals / channels reception and the traffic channel transmission, and retain the transmission or reception (detection) process with the higher priority. Alternatively, compare the priority of the traffic channel with a configured or pre-configured decision threshold. If the priority of the traffic channel is higher than or not lower than the decision threshold, retain the transmission of the traffic channel; if the priority of the traffic channel is lower than the decision threshold, retain the reception (detection) of the synchronization signals / channels.

[0086] Solution 7): For a sidelink synchronization period, if there are multiple synchronization resources, for the synchronization resources that do not transmit sidelink synchronization signals / channels, compare the priority of the traffic channel with the reception priority of the sidelink synchronization signals / channels, or compare the priority of the traffic channel with a configured or pre-configured decision threshold. If the priority of the traffic channel is not lower than the reception priority of the sidelink synchronization signals / channels or not lower than the configured or pre-configured decision threshold, retain the transmission of the traffic channel.

[0087] Solution 8): When the transmission of sidelink synchronization signals / channels (the first signals / channels) overlaps with the transmission or reception of other signals / channels (the second signals / channels, including PSFCH, SL CSI-RS, SL PT-RS, PSCCH), compare the transmission priority or reception priority of the other signals / channels with the transmission priority of the sidelink synchronization signals / channels, or compare the transmission priority of the other signals / channels with the value of a configured or pre-configured decision threshold. If the transmission priority or reception priority of the other signals / channels is higher than or not lower than the transmission priority of the sidelink synchronization signals / channels, or the transmission priority or reception priority of the other signals / channels is higher than or not lower than the decision threshold, retain the transmission or reception of the other signals / channels.

[0088] Solution 9): The description in Solution 8 above also applies to the reception (detection) of sidelink synchronization signals / channels, and the reception priority of the sidelink synchronization signals / channels can be different from the transmission priority of the sidelink synchronization signals / channels.

[0089] Solution 10): Define that the priority of the PSFCH is associated with the priority of the corresponding PSSCH, including: being the same as the priority of the corresponding PSSCH, being associated with the priority of the corresponding PSSCH, increasing the priority or decreasing the priority based on the priority of the corresponding PSSCH.

[0090] Another embodiment of this application includes the following embodiments:

[0091] Embodiment 1:

[0092] This embodiment describes a method for transmitting wireless signals / channels. Taking the transmission of sidelink signals and / or channels as an example, as shown. LTE V2X and NR V2X coexist in the same UE and operate on different carriers (carrier 1 and carrier 2) of the same frequency band (band). When the traffic signals and / or channels transmitted by one RAT (Radio Access Technology) overlap with the sidelink synchronization signals and / or channels transmitted by another RAT in the time domain, the UE determines whether to transmit the traffic signals and / or channels according to the priority judgment result. Alternatively, it may also include determining whether to transmit and / or receive sidelink synchronization signals and / or channels. The aforementioned time-domain overlap can also be understood as the wireless resources for transmitting signals and / or channels overlapping in the time domain; the aforementioned priority judgment result includes the judgment result of comparing the priority values of traffic signals and / or channels with the priority values of sidelink synchronization signals and / or channels. The aforementioned UE determines whether to transmit traffic signals and / or channels according to the priority judgment result, specifically including: if the priority value of the traffic signals and / or channels is less than or not greater than the priority value of the sidelink synchronization signals and / or channels, then transmit the traffic signals and / or channels, or rather, abandon transmitting the sidelink synchronization signals and / or channels; otherwise, abandon transmitting the traffic signals and / or channels, or rather, transmit the sidelink synchronization signals and / or channels; the aforementioned may also include determining whether to transmit and / or receive sidelink synchronization signals and / or channels, specifically including: if the priority value of the traffic signals and / or channels is not less than or greater than the priority value of the sidelink synchronization signals and / or channels, then transmit and / or receive the sidelink synchronization signals and / or channels, or rather, abandon transmitting the traffic signals and / or channels; otherwise, abandon transmitting and / or receiving the sidelink synchronization signals and / or channels, or rather, transmit the traffic signals and / or channels.

[0093] Figure 3In the example, it is assumed that the sidelink synchronization resource on carrier 1 overlaps with the sidelink data channel resource on carrier 2. Here, the sidelink traffic channel can be the PSSCH (Physical Sidelink Shared Channel), and / or the PSCCH (Physical Sidelink Control Channel), and / or the PSFCH (Physical Sidelink Feedback Channel). For example, if there is a transmission of the PSSCH of NR V2X in the overlapping resource of carrier 2, and / or there is a transmission of the SLSS / PSBCH (Sidelink Synchronisation Signal / Physical Sidelink Broadcast Channel) of LTE V2X in the overlapping resource of carrier 1, the overlapping resource here refers to the temporal overlap between the traffic channel resources and the synchronization signal / channel resources on different carriers. Compare the priority of the PSSCH of NR V2X with the priority of the SLSS / PSBCH of LTE V2X, and determine whether to transmit the sidelink data channel according to the comparison result of the priorities. For instance, if the priority value of the PSSCH of NR V2X is less than or not greater than the priority value of the SLSS / PSBCH of LTE V2X, then transmit the PSSCH of NR V2X, or in other words, abandon the transmission or reception of the SLSS / PSBCH of LTE V2X; otherwise, abandon the transmission of the PSSCH of NR V2X, or in other words, transmit or receive the SLSS / PSBCH of LTE V2X.

[0094] The service signals / channels described in this embodiment include sidelink service signals / channels, such as PSSCH, and also include service signals / channels for cellular communication, such as the uplink transmission PUSCH (Physical Uplink Shared Channel). This embodiment is also applicable to determining whether to receive service signals / channels, specifically including: If the priority of the service signal / channel is known, and the value of the priority of the service signal and / or channel is less than or not greater than the value of the priority of the sidelink synchronization signal and / or channel, then receive the service signal and / or channel, or in other words, abandon sending and / or receiving the sidelink synchronization signal or channel; otherwise, abandon receiving the service signal and / or channel, or in other words, send or receive the sidelink synchronization signal or channel. It may also include: If the priority of the service signal / channel is not known, then abandon receiving the service signal and / or channel, or in other words, send and / or receive the sidelink synchronization signal or channel. The object described above, whether the priority of the service signal / channel is known or not, can refer to the UE or the RAT module. The sidelink synchronization signals / channels described in this embodiment include the SLSS / PSBCH of LTE V2X and the S-SSB (Sidelink Synchronization Signal / PSBCH Block) of NR V2X.

[0095] The priority of the signals / channels described in this embodiment can be determined according to high-layer configuration signaling or pre-configuration, or be a fixed value, or be determined according to physical layer indication information, such as being determined according to the indication of DCI (Downlink Control Information) or SCI (Sidelink Control Information).

[0096] In this embodiment, the priority of the described PSSCH comes from the indication in the PSCCH or SCI corresponding to the PSSCH. Examples where the channel for transmission or reception is a Standalone SCI are also applicable to this embodiment.

[0097] In this embodiment, it is described in terms of service signals and / or channels, and sidelink synchronization signals and channels, but the method of this embodiment is equally applicable to the case including the physical sidelink feedback channel.

[0098] Embodiment 2:

[0099] This embodiment describes a method for determining the priority of wireless signals / channels, including how to determine the priority of sidelink synchronization signals / channels. Taking the SLSS / PSBCH of LTE V2X as an example, the priority of SLSS / PSBCH is determined according to the synchronization reference source to which the UE transmitting the SLSS / PSBCH is synchronized, and the priorities of SLSS / PSBCH corresponding to different synchronization reference sources can be different.

[0100] For example, as shown, if the UE transmitting the SLSS / PSBCH is directly synchronized to the timing of the base station (such as eNB or gNB), then the value of the priority for transmitting and / or receiving the corresponding SLSS / PSBCH is P1. If the UE transmitting the SLSS / PSBCH is indirectly synchronized to the timing of the base station (such as eNB or gNB), including synchronizing to the timing of the base station by detecting the synchronization signals forwarded by other UEs, where the other UEs include UEs directly or indirectly synchronized to the base station (such as eNB or gNB), then the value of the priority for transmitting and / or receiving the corresponding SLSS / PSBCH is P2. If the UE transmitting the SLSS / PSBCH is directly synchronized to an external unified timing (such as GNSS), then the value of the priority for transmitting and / or receiving the corresponding SLSS / PSBCH is Q1. If the UE transmitting the SLSS / PSBCH is indirectly synchronized to an external unified timing (such as the global navigation satellite system GNSS), including synchronizing to the external unified timing by detecting the synchronization signals forwarded by other UEs, where the other UEs include UEs directly or indirectly synchronized to the external unified timing (such as GNSS), then the value of the priority for transmitting and / or receiving the corresponding SLSS / PSBCH is Q2. If the UE transmitting the SLSS / PSBCH is synchronized to other timings (such as the timing of an independent UE), including directly or indirectly to other timings, then the value of the priority for transmitting and / or receiving the corresponding SLSS / PSBCH is R1.

[0101] This embodiment is described by taking the SLSS / PSBCH of LTE V2X as an example. It should be noted that this embodiment is also applicable to the determination of the priority of S-SSB in NR V2X.

[0102] Embodiment 3:

[0103] This embodiment describes a method for determining the priority of wireless signals / channels, including how to determine the priority of sidelink synchronization signals / channels. Taking the SLSS / PSBCH of LTE V2X as an example, the priority of SLSS / PSBCH is determined according to the corresponding synchronization reference level (or hop count) of the UE transmitting the SLSS / PSBCH, and the priorities of SLSS / PSBCH corresponding to different synchronization reference levels can be different.

[0104] For example, as Figure 3 Figure 4 Figure 5 shown, the UE that transmits SLSS / PSBCH is the first-level synchronization reference. For example, it is synchronized to the base station (eNB or gNB) or GNSS. Then, the value of the priority corresponding to the transmission and / or reception of SLSS / PSBCH is P1; the UE that transmits SLSS / PSBCH is the second-level synchronization reference, that is, the UE synchronized to the first-level synchronization reference. Then, the value of the priority corresponding to the transmission and / or reception of SLSS / PSBCH is P2; the UE that transmits SLSS / PSBCH is the third-level synchronization reference, that is, the UE synchronized to the second-level synchronization reference. Then, the value of the priority corresponding to the transmission and / or reception of SLSS / PSBCH is P3; in this order, the priority of the Nth-level synchronization reference UE corresponding to the transmission and / or reception of SLSS / PSBCH can be determined as PN, where N is a positive integer. It is also possible to set the priority of the synchronization reference UE after the Mth level corresponding to the transmission and / or reception of SLSS / PSBCH as PM, where M is a positive integer.

[0105] This embodiment is described by taking the SLSS / PSBCH of LTE V2X as an example. It should be noted that this embodiment is also applicable to the priority determination of S-SSB of NR V2X.

[0106] Embodiment 4:

[0107] This embodiment describes a method for determining the priority of a wireless signal / channel, including how to determine the priority of a sidelink synchronization signal / channel. It is described by taking the SLSS / PSBCH of LTE V2X and the S-SSB of NR V2X as examples. According to the RAT corresponding to the transmitted sidelink synchronization signal / channel, the priority of the sidelink synchronization signal / channel is determined, and the priorities of the sidelink synchronization signals / channels corresponding to different RATs can be different.

[0108] For example, the priority of the SLSS / PSBCH of LTE V2X is Q1, and the priority of the S-SSB of NR V2X is Q2. When the transmission resource of the data channel overlaps with the resource of the sidelink synchronization signal / channel in the time domain, when making a priority judgment with the data channel, during the comparison, if the sidelink synchronization signal / channel is the SLSS / PSBCH of LTE V2X, then the corresponding priority is Q1, and if the sidelink synchronization signal / channel is the S-SSB of NR V2X, then the corresponding priority is Q2.

[0109] In this embodiment, the values of Q1 and Q2 can be fixed values or configured values.

[0110] Embodiment 5:

[0111] This embodiment describes a method for transmitting wireless signals / channels, including comparing the priority of service signals and / or channels with a decision threshold A, where the decision threshold A is determined according to configuration or pre-configuration, or determined according to physical layer indication information, such as determined according to the indication of DCI or SCI. On the resources overlapping with the resources of the sidelink synchronization signal / channel, it is determined whether to transmit the service signal and / or channel according to the comparison between the priority of the service signal and / or channel to be transmitted and the decision threshold A. Specifically, if the value of the priority is less than or not higher than the value of the decision threshold A, the service signal and / or channel is transmitted, or in other words, the transmission or reception of the sidelink synchronization signal and / or channel is abandoned; otherwise, the transmission of the service signal and / or channel is abandoned, or in other words, the sidelink synchronization signal and / or channel is transmitted or received.

[0112] For example, NR V2X and LTE V2X coexist in UE1. NR V2X transmits PSSCH on carrier 2, and the transmission resources overlap with the resources where LTE V2X transmits or receives SLSS / PSBCH on carrier 1 in the time domain. The UE compares the priority of the PSSCH to be transmitted with the decision threshold A. The value of A is determined according to configuration or pre-configuration, or determined according to physical layer indication information. Assume that the priority value of the PSSCH to be transmitted is 1, and the value of the configured or pre-configured decision threshold A is 4. Assume that the priority mapping rule is that the smaller the value of the priority, the higher the priority. Then it can be judged that the priority of the PSSCH to be transmitted by NR V2X is higher than the decision threshold A. Then the PSSCH of NR V2X is transmitted on carrier 2, and / or the transmission or reception of SLSS / PSBCH of LTE V2X is abandoned on the overlapping resources on carrier 1.

[0113] If the transmitted or received channel is a Standalone SCI, the method of this embodiment is also applicable.

[0114] The method of this embodiment is not limited to the case where NR V2X and LTE V2X coexist in the same UE. It is also applicable to the case where sidelink communication and cellular communication, such as sidelink data transmission and cellular uplink transmission, coexist in the same UE, and is also applicable to the case of coexisting on different carriers or the same carrier.

[0115] Another example, NR V2X coexists with uplink transmission in UE2. NR V2X sends S-SSB on carrier 2, and the resources of uplink transmission (such as PUSCH) on carrier 1 overlap with the resources for sending or receiving S-SSB on carrier 2. The UE compares the priority of the PUSCH to be sent with the decision threshold A. Suppose the priority value of the PUSCH to be sent is 2, and the configured or pre-configured value of decision threshold A is 3. Assuming that the priority mapping rule is that the smaller the priority value, the higher the priority, then it can be determined that the priority of the PUSCH to be sent for uplink transmission is higher than the decision threshold A. Then, send the PSSCH of NR V2X on carrier 1, and / or abandon sending or receiving the S-SSB of NR V2X on the overlapping resources on carrier 2.

[0116] In this embodiment, the priority of the described PSSCH comes from the indication in the PSCCH corresponding to the PSSCH.

[0117] Embodiment 6:

[0118] This embodiment describes a method for transmitting a wireless signal / channel, including associating the priority of wireless signal and / or channel 2 with the priority of wireless signal and / or channel 1. It includes: determining the priority of wireless signal and / or channel 2 according to the priority of wireless signal and / or channel 1, including being the same as the priority of wireless signal and / or channel 1 or adjusting based on the priority of wireless signal and / or channel 1; or, not performing a priority comparison on wireless signal and / or channel 2, and adopting the same transmission or reception processing as wireless signal and / or channel 1. The priority of the signal and / or channel described here can be the transmission priority, reception priority, or the priority of transmission and reception. The signal and / or channel 1 and signal and / or channel 2 described here can be transmission signals and / or channels or reception signals and / or channels.

[0119] For example, the physical sidelink feedback channel (PSFCH) maintains the same priority as the physical sidelink shared channel (PSSCH). Or, when the feedback content includes ACK or NACK, the PSFCH maintains the same priority as the PSSCH corresponding to the ACK or NACK. The PSFCH and PSSCH described here are on the same carrier, and the transmitted PSFCH corresponds to the received PSSCH, that is to say, the transmitted PSFCH corresponds to the received PSSCH, and the received PSFCH corresponds to the transmitted PSSCH. The PSSCH corresponding to the above-described ACK or NACK also refers to this corresponding relationship.

[0120] For another example, the PSFCH transmitted on carrier 1 has the same priority as the received PSSCH1, and there is an overlap with the resources of the transmitted PSSCH2 on another carrier. Assuming that the priority of PSSCH1 is higher than that of PSSCH2, it is considered that the priority of PSFCH is also higher than that of PSSCH2. Or, if the ACK or NACK carried by the PSFCH on carrier 1 corresponds to PSSCH1, the PSFCH adopts the same processing as PSSCH1. In other words, when PSSCH1 is transmitted, the PSFCH is also transmitted; when PSSCH1 abandons transmission, the PSFCH also abandons transmission.

[0121] In this embodiment, the priority of the described PSSCH comes from the indication in the PSCCH corresponding to the PSSCH.

[0122] Embodiment 7:

[0123] A method for transmitting a wireless signal / channel may further include determining the transmission priority of the wireless signal and / or channel according to the transmission mode or the content carried by the wireless signal and / or channel. For example, when the content transmitted by the PSFCH can only contain NACK, that is, only NACK is fed back (for example, the feedback mode of NR V2X is option 1), the PSFCH adopts the same priority as the corresponding PSSCH, that is, on the same carrier, the priority of the transmitted PSFCH is the same as that of the corresponding received PSSCH, and the priority of the received PSFCH is the same as that of the corresponding transmitted PSSCH. Based on the comparison result of the priority of the PSFCH with other signals and / or channels, it is determined whether to transmit or receive the PSFCH. For example, if the priority of the PSFCH is high (for example, the value of the priority is small), the PSFCH is transmitted or received. Here, the other signals and / or channels can be on the same carrier or on different carriers, and there is an overlap with the resources of the PSFCH in the time domain.

[0124] For another example, if the content sent by the PSFCH may be an ACK or a NACK, that is, the content sent by the PSFCH may contain an ACK or a NACK (for example, the feedback method of NR V2X is option 2), the PSFCH adopts the same priority as the corresponding PSSCH, that is, on the same carrier, the priority of the sent PSFCH is the same as the priority of the corresponding received PSSCH, and the priority of the received PSFCH is the same as the priority of the corresponding sent PSSCH. Alternatively, the priority of the sent PSFCH is adjusted (relative to the priority of the corresponding PSSCH on the same carrier), such as decreasing or increasing the priority. As an example, the received PSFCH adopts the same priority as the corresponding sent PSSCH on the same carrier, and based on the priority comparison result between the PSFCH and other signals and / or channels, it is determined whether to receive the PSFCH. For example, if the PSFCH priority is high, then the PSFCH is received. The other signals and / or channels here can be on the same carrier or on different carriers, and there is an overlap in time domain with the resources of the PSFCH. Another example, the priority of the sent PSFCH is determined according to the content sent. If the content sent is an ACK, then the PSFCH adopts the same priority as the corresponding received PSSCH on the same carrier, and based on the priority comparison result between the PSFCH and other signals and / or channels, it is determined whether to send the PSFCH. For example, if the PSFCH priority is high, then the PSFCH is sent. The other signals and / or channels here can be on the same carrier or on different carriers, and there is an overlap in time domain with the resources of the PSFCH. If the content sent is a NACK, then the priority of the PSFCH is decreased, such as decreased to the lowest priority, and based on the priority comparison result between the PSFCH and other signals and / or channels, it is determined whether to send the PSFCH.

[0125] For another example, if the PSSCH is received on the same carrier, then the priority of the corresponding sent PSFCH is adjusted, such as increasing the priority of the sent PSFCH to the highest. Alternatively, when the transmission or reception of the PSFCH overlaps with the resources of the PSSCH of LTE V2X, the PSSCH of LTE V2X is preferentially transmitted or received, and LTE V2X and the PSFCH can be on the same or different carriers.

[0126] In this embodiment, the priority of the described PSSCH comes from the indication in the PSCCH corresponding to the PSSCH.

[0127] Embodiment 8:

[0128] This embodiment describes that the resources for transmitting or receiving SLSS and / or PSBCH of LTE V2X overlap with those of S-SSB of NR V2X in the time domain, including on the same carrier or different carriers. SLSS and / or PSBCH and S-SSB can determine whether to transmit or receive based on a priority comparison. For example, the priority value of SLSS and / or PSBCH is 3, and the priority value of S-SSB is 4. Based on the priority comparison, if the priority of SLSS and / or PSBCH is higher, the UE transmits SLSS and / or PSBCH. It is also possible to fix the transmission priority of one or both RATs to be higher than that of the other RAT. For example, the transmission and / or reception priority of SLSS and / or PSBCH is always higher than that of S-SSB, or fix the priority of SLSS and / or PSBCH to a priority value, compare it with the priority value of S-SSB, or respectively fix the priorities of both SLSS and / or PSBCH and S-SSB to a priority value and perform a comparison of the priority values.

[0129] Embodiment 9:

[0130] This embodiment describes that the resources for transmitting or receiving SLSS and / or PSBCH of LTE V2X overlap with those of PSFCH of NR V2X in the time domain. Compare the transmission priority or reception priority of SLSS and / or PSBCH with the transmission and / or reception priority of PFSCH. A smaller priority value indicates a higher priority. According to the priority comparison, retain the processing of the transmission or reception with a higher priority.

[0131] In another way, compare the transmission priority or reception priority of PFSCH with the value of a decision threshold. If the value of the transmission priority or reception priority is less than or not greater than the decision threshold, retain the transmission or reception of PFSCH; otherwise, transmit or receive SLSS and / or PSBCH.

[0132] In one embodiment, when the resources for transmitting or receiving SLSS and / or PSBCH of LTE V2X overlap with those of PSFCH of NR V2X in the time domain, give priority to transmitting or receiving SLSS and / or PSBCH; or fix the priority value of SLSS and / or PSBCH of LTE V2X to a fixed value and compare it with the priority value of the transmission or reception of PFSCH. This example is also applicable to the transmission or reception of S-SSB of NRV2X.

[0133] Embodiment 10:

[0134] This embodiment describes determining the priority of sidelink transmission and / or reception, including at least one of the following methods:

[0135] Define the value of the priority for transmitting or receiving the sidelink synchronization signal and / or channel as one value within the valid value range of the priority value of the logical channel or logical channel group. For example, define the priority value of the synchronization signal and / or channel SLSS / PSBCH of LTE V2X as one value from 1 to 8, such as 3. It is also possible to define the transmission priority and reception priority of SLSS / PSBCH separately, and the defined priorities can be the same value or different values. For example, the transmission priority value of SLSS / PSBCH is 2, and the reception priority value of SLSS / PSBCH is 4. Among them, SLSS includes PSSS and / or SSSS. Another example, for instance, define the priority value of the synchronization signal and / or channel S-SSB of NR V2X as one value from 1 to 16, such as 4. It is also possible to define the transmission priority and reception priority of SLSS / PSBCH separately, and the defined priorities can be the same value or different values. For example, the transmission priority value of S-SSB is 1, and the reception priority value of SLSS / PSBCH is 3.

[0136] Define that the priority for transmitting or receiving PFSCH is the same as or associated with the priority value of PSSCH, where there is a corresponding relationship between PSSCH and PFSCH. Specifically, the ACK and / or NACK carried by PSFCH correspond to the above-mentioned PSSCH. For example, the transmission priority of PSFCH is the same as the priority of the associated PSSCH received on the same carrier, and the reception priority of PSFCH is the same as the priority of the associated PSSCH transmitted on the same carrier. Or, the transmission priority value of PSFCH is increased or decreased by M compared with the priority value of the associated PSSCH received on the same carrier, and the reception priority value of PSFCH is increased or decreased by N compared with the priority value of the associated PSSCH transmitted on the same carrier, where M and N are positive integers, and ensure that the values of the transmission priority and reception priority of PSFCH are within the valid range.

[0137] Define that the priority of SL PT-RS (Sidelink Phase-tracking reference signal) is the same as the priority value of the associated PSSCH. For example, when the resources for transmitting or receiving SL PT-RS overlap in the time domain with the resources for transmitting or receiving other signals or channels, SL PT-RS is compared with the priorities of other signals or channels according to the priority of its corresponding PSSCH. Here, other signals or channels include one or more of sidelink synchronization signals or channels, PSFCH, PSSCH, and PSCCH.

[0138] Define the priority value of the SL CSI-RS (Sidelink Channel-state information reference signal) as a value within the valid value range of the priority value of a logical channel or a logical channel group. For example, define the priority value of the SL CSI-RS as a value from 1 to 16, such as 4. It is also possible to define the transmission priority and the reception priority of the SL CSI-RS separately, and the defined priorities can be the same value or different values. For example, the transmission priority value of the SL CSI-RS is 1, and the reception priority value of the SL CSI-RS is 3.

[0139] Embodiment 11:

[0140] This embodiment describes the comparison between the priorities corresponding to different signal or channel transmissions. The priority values of signal or channel transmissions in LTE V2X are values from 1 to 8, and the priority values of signal or channel transmissions corresponding to NR V2X are values from 1 to 16. When comparing them, the comparison is based on a mapping rule between these two priority values. The mapping rule includes one or more of the following:

[0141] Multiple priority values of NR V2X are mapped to one priority value of LTE V2X. The priority values 2n - 1 and 2n of NR V2X are mapped to the priority value n of LTE V2X, where n is a positive integer from 1 to 8. For example, the priority values 1 and 2 of NR V2X are mapped to the priority value 1 of LTE V2X, the priority values 3 and 4 of NR V2X are mapped to the priority value 2 of LTE V2X, and so on. The priority values 15 and 16 of NR V2X are mapped to the priority value 8 of LTE V2X.

[0142] High-priority alignment mapping. For example, the priority values 1 to 8 of NR V2X are respectively mapped to the priority values 1 to 8 of LTE V2X in sequence, and the priority values 9 to 16 of NR V2X are mapped to the priority value 8 of LTE V2X.

[0143] Low-priority alignment mapping. For example, the priority values 9 to 16 of NR V2X are respectively mapped to the priority values 1 to 8 of LTE V2X in sequence, and the priority values 1 to 8 of NR V2X are mapped to the priority value 1 of LTE V2X.

[0144] Mapping according to the corresponding priority value. The priority value n of LTE V2X is mapped to the priority value n of NR V2X, where n is a positive integer from 1 to 8. For example, the priority values 1 to 8 of LTE V2X are respectively mapped to the priority values 1 to 8 of NR V2X in sequence.

[0145] Uniform mapping according to the priority value. The priority value n of LTE V2X is mapped to the priority value 2n or 2n - 1 of NR V2X, where n is a positive integer from 1 to 8. For example, the priority values 1 to 8 of LTE V2X are sequentially mapped to the priority values 1, 3, 5, 7, 9, 11, 13, 15 of NR V2X respectively.

[0146] The transmission of the signal and / or channel described in this embodiment includes the sending or transmission of the signal and / or channel.

[0147] The time-domain overlap described in all the above embodiments includes partial or complete overlap of different signal and / or channel transmissions (including sending or receiving) or radio resources. The abandonment of sending or non-sending or drop described in all embodiments includes processing methods such as canceling the current sending, suspending the current sending, or sending using rate matching.

[0148] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by means of software plus a necessary general hardware platform.
