Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and more specifically, to a control method for user equipment and corresponding user equipment. Background Art

[0002] Vehicle to Everything (V2X) is a new generation of information and communication technology that connects vehicles to everything, where V stands for vehicle and X stands for any object that interacts with the vehicle. Currently, X mainly includes vehicles, people, roadside infrastructure and networks.

[0003] In a pair of UEs performing V2X service communications, such as UE A and UE B, in order to obtain link quality information, UE A can request UE B to report CSI (Channel State Information). Based on the CSI request, UE B will generate a corresponding CSI report and send the CSI report to UE A. Among them, the CSI report is transmitted on the PSSCH channel, and can be carried on the PSSCH channel in a punctured coded manner. The MAC PDU (MAC protocol data unit) can be transmitted on the PSSCH channel, or the MAC PDU cannot be transmitted; the CSI report can also be carried in a MAC CE (MAC control element), and then the MAC CE is encapsulated into a MAC PDU and transmitted through the PSSCH channel.

[0004] In PC5 communication, the transmission of the PSSCH channel is scheduled by SCI (Side Connection Control Information). The SCI indicates the time domain and frequency domain information of the scheduled PSSCH channel transmission, and also indicates the QoS (Quality of Service) related information of the PSSCH transmission, such as priority, latency, reliability, etc. How to set the corresponding QoS related information in SCI according to the information transmitted on the PSSCH channel is a problem that needs to be solved.

[0005] In addition, when the transmission of PSSCH conflicts with the transmission of PUCCH or PUSCH, how to determine which channel to send first is also a problem that needs to be solved. Summary of the invention

[0006] In order to solve at least a part of the above problems, the present invention provides a method for controlling a user equipment and a user equipment.

[0007] According to a first aspect of the present invention, a control method for a user equipment UE is provided, comprising: the UE receiving a channel state information CSI request sent by other user equipment UE; based on the CSI request, the UE generating a channel state information CSI report transmitted via a PSSCH channel, and side connection control information SCI for scheduling indication of transmission of the PSSCH channel; and setting a QoS parameter related to a service quality Qos of the PSSCH transmission contained in the SCI based on whether the PSSCH channel carries a MAC protocol data unit MAC PDU.

[0008] In the above method, when the MAC PDU is carried on the PSSCH channel, the Qos parameter may be set based on the number of MAC service data units MAC SDUs contained in the MAC PDU.

[0009] In the above method, when the MAC PDU contains one MAC SDU, the value of the Qos parameter corresponding to the MAC SDU can be used as the value of the Qos parameter corresponding to the MAC PDU; when the MAC PDU contains multiple MAC SDUs, the highest value or the lowest value of the Qos parameters corresponding to the multiple MAC SDUs can be used as the value of the Qos parameter corresponding to the MAC PDU; when the MAC PDU does not contain the MAC SDU, the Qos parameter corresponding to the MAC PDU can be set to a fixed value, or the value of the Qos parameter corresponding to the MAC PDU can be set based on specified parameters.

[0010] In the above method, when the MAC SDU is not included in the MAC PDU, the Qos parameter corresponding to the MAC PDU may be used as the Qos parameter included in the SCI carrying the CSI report.

[0011] In the above method, when the MAC PDU is not carried on the PSSCH channel, the value of the Qos parameter in the SCI can be set to a fixed value, or the value of the Qos parameter in the SCI can be set based on a specified parameter.

[0012] In the above method, when the MAC PDU is not carried on the PSSCH channel, the SCI generated by the UE may not include or omit information on Qos parameters.

[0013] In the above method, the QoS parameters in the SCI may include priority, latency, and reliability.

[0014] In the above method, the MAC PDU may include a MAC header and padding bits. When the logical channel or logical channel number contained in the MAC PDU corresponds to the padding bits, the Qos parameter corresponding to the MAC PDU is set to a fixed value, or the value of the Qos parameter corresponding to the MAC PDU is set based on the specified parameters.

[0015] In the above method, the specified parameter is a priority threshold.

[0016] According to a second aspect of the present invention, there is provided a user equipment, comprising: a processor; and a memory storing instructions; wherein the instructions, when executed by the processor, execute the control method of the user equipment according to the context.

[0042] In this article, the terms sidelink and V2X can be used interchangeably.

[0043] Next, the control method of the user equipment UE in the present invention is described. Specifically, as an example, Figure 1 A flow chart of a control method 100 of a user equipment UE according to an embodiment of the present disclosure is shown.

[0044] In step S101, the user equipment UE receives a channel state information CSI request sent by other user equipment UE. Another implementation of step S101 may be that the user equipment UE receives configuration information, which is sent by other user equipment UE or by a base station, and the configuration information configures an indication or request for the user equipment UE to perform periodic reporting of channel state information CSI.

[0045] In step S102, the user equipment UE generates a CSI report transmitted through the PSSCH channel and side connection control information SCI for scheduling the transmission of the PSSCH channel based on the received CSI request;

[0046] In step S103, the user equipment UE sets the QoS parameters related to the service quality Qos of the PSSCH transmission contained in the SCI based on whether the PSSCH channel carries the MAC protocol data unit MAC PDU.

[0047] The QoS parameters included in the above SCI may include, for example, priority, latency, reliability, etc.

[0048] Figure 2 This is a specific example of setting the QoS parameters included in the SCI based on whether the PSSCH channel carries a MAC PDU.

[0049] For example, when the MAC PDU is carried on the PSSCH channel, the Qos parameter may be set based on the number of MAC SDUs included in the MAC PDU.

[0050] As an example, when the MAC PDU contains one MAC SDU, the value of the Qos parameter corresponding to the MAC SDU is used as the value of the Qos parameter corresponding to the MAC PDU; when the MAC PDU contains multiple MAC SDUs, the highest value or the lowest value of the Qos parameters corresponding to the multiple MAC SDUs is used as the value of the Qos parameter corresponding to the MAC PDU; when the MAC PDU does not contain the MAC SDU, the Qos parameter corresponding to the MAC PDU is set to a fixed value, or the value of the Qos parameter corresponding to the MAC PDU is set based on specified parameters.

[0051] In addition, for example, when the MAC SDU is not included in the MAC PDU, the Qos parameters corresponding to the MAC PDU may also be used as the Qos parameters included in the SCI carrying the CSI report.

[0052] Furthermore, when the MAC PDU is not carried on the PSSCH channel, the value of the Qos parameter in the SCI can be set to a fixed value, or the value of the Qos parameter in the SCI can be set based on specified parameters, or the information of the Qos parameter can be not included or omitted in the SCI.

[0053] Hereinafter, specific examples and embodiments of the present invention will be described in detail. As described above, the examples and embodiments described in the present disclosure are provided for easy understanding of the present invention and are not intended to limit the present invention.

[0054] Example 1

[0055] Embodiment 1 provides a method for determining QoS parameters of a transport block. A transport block may include at least one MAC PDU. A MAC PDU may include zero, one or more MAC SDUs.

[0056] MAC SDU contains service data sent from the upper layer. The service flow to which these service data belong has corresponding QoS requirements, namely priority, latency, and reliability. These QoS-related parameters have corresponding values ​​according to the service type or service characteristics to which the data belongs.

[0057] If the MAC PDU contains only one MAC SDU, then the value of the Qos parameter corresponding to this MAC SDU can be used as the value of the Qos parameter corresponding to this MAC PDU, and then can be used as the value of the Qos parameter of the TB carrying this MAC PDU.

[0058] If a MAC PDU contains multiple MAC SDUs, and these MAC SDUs do not belong to the same service flow, the values ​​of the Qos parameters corresponding to each SDU may be different. Then the value with the highest (or lowest) priority value among these MAC SDUs can be corresponded to the priority of the MAC PDU, and the value with the shortest (or longest) delay value can be corresponded to the delay value of the MAC PDU, or the value with the highest (or lowest) reliability requirement value can be corresponded to the reliability requirement value of the MAC PDU. Then it can be used as the value of the Qos parameter of the TB carrying this MAC PDU. Another implementation of this process can be to determine the Qos parameter of the MAC PDU based on the Qos parameter of the logical channel. Since each MAC SDU has its corresponding logical channel, the logical channel has a corresponding number / identifier, which is called the logical channel ID. Each configured logical channel has its corresponding Qos parameter, especially the priority parameter. The values ​​of these parameters are pre-configured, which can be configured by the base station / network side sending configuration information to the UE, or it can be a pre-configured value. Then the highest (or lowest) priority value corresponding to the logical channel ID to which these MAC SDUs belong can be used as the priority of the MAC PDU, the shortest (or longest) delay value can be used as the delay value of the MAC PDU, or the highest (or lowest) reliability requirement value can be used as the reliability requirement value of the MAC PDU. Furthermore, the value can be used as the value of the Qos parameter of the TB carrying this MAC PDU.

[0059] If the MAC PDU does not include a MAC SDU, then the MAC PDU may only include a MAC header and padding bits, wherein the MAC header may include an SL-SCH subheader and a MAC subheader corresponding to the padding bits, or the MAC PDU may only include a MAC header, a MAC CE, and / or padding bits, wherein the MAC header may include an SL-SCH subheader and a MAC subheader corresponding to the MAC CE, or a MAC subheader corresponding to the padding bits. The SL-SCH subheader may carry the address information of the MAC PDU, such as the destination address ID (destination ID) and / or the source address ID (sourceID). The Qos parameters corresponding to such a MAC PDU may be set to fixed values:

[0060] For example, when setting the priority, if the value corresponding to the highest / lowest priority is 0, then the priority of the MAC PDU is set to 0; when setting the delay, if the value corresponding to the shortest / longest delay is 1, then the shortest delay corresponding to the MAC PDU is set to 1; if the value of the highest / lowest level of reliability requirement is 8, then the reliability requirement corresponding to the MAC PDU is set to 8. In short, it can be set to a fixed value.

[0061] Such a fixed value can also be configured on the network side. The UE receives configuration information sent by the network side or the base station, which includes configuration information indicating the value of the corresponding Qos parameter for a MAC PDU that does not contain a MAC SDU. The UE can then determine the value of the Qos parameter corresponding to such a MAC PDU based on the configuration.

[0062] In addition, it can also be a preconfigured fixed value. The value of the corresponding QoS parameter can also be set based on a certain parameter. For example, when setting the priority corresponding to the MAC PDU, it can be set based on the priority threshold value. The priority value can be set higher than or equal to the threshold value, and can also be set lower than the priority threshold value.

[0063] The priority threshold here refers to the threshold used to determine whether the transmitted data meets the threshold requirement: when the priority corresponding to the transmitted data is higher than the threshold, the data can be sent first. The priority here refers to the data packet sent over the air interface, that is, the data packet sent by the UE to the Uu interface of the gNB. When the resources used to send air interface data packets conflict with the resources used to send V2X data packets, for example, there is an overlap in the time domain resources or in the frequency domain resources, the UE can compare the priority corresponding to the v2x data packet used to send with the above-mentioned priority threshold. If the priority corresponding to the data is higher than the threshold, the UE sends the v2x data packet. Otherwise, when it is lower than the threshold, the UE sends the air interface data packet first.

[0064] Since the MAC subheader corresponding to the padding bit (or MAC CE) carries a logical channel ID, the logical channel ID is used to identify that it corresponds to the padding bit (or MAC CE). Therefore, for a MAC PDU, when determining its corresponding priority, it can be determined according to the logical channel included in the MAC PDU.

[0065] One implementation of the above scheme may be: for a MAC PDU, when determining its corresponding Qos parameter, it can be determined according to the value of the Qos parameter corresponding to the logical channel contained in the MAC PDU. Taking priority as an example, when the MAC SDU and MAC CE (or padding bit) are included in this MAC PDU, the logical channel to which the MAC SDU belongs has its corresponding priority value, and the logical channel ID to which the MAC CE (or padding bit) belongs is used to identify the MAC CE (or padding bit). It can be considered that the value of the priority corresponding to such a logical channel can be determined according to the method described above, and then it can be considered as the priority corresponding to the logical channel ID. Then, the priority values ​​of these logical channels (corresponding to the MAC SDU and corresponding to the MAC CE or padding bit) are compared, and the maximum or minimum value is taken as the value of the priority corresponding to the MAC PDU, and then it can be used as the value of the priority corresponding to the TB containing the MAC PDU.

[0066] For a MAC PDU, if the MAC PDU contains only one logical channel / logical channel number, and the logical channel / logical channel number contained in the MAC PDU corresponds to or identifies a padding bit (or MAC CE), then the value of the corresponding Qos parameter of the MAC PDU can be considered or set to be a fixed value or based on a certain parameter. The specific setting method is described above.

[0067] Example 2

[0068] When performing V2X communication based on PC5, in order to send MAC PDU, the UE generates SCI to indicate the resource information of the PSSCH channel for transmitting MAC PDU. This PSSCH can be called SCI-scheduled PSSCH. Among them, the MAC PDU is carried in the transport block (transport block TB) transmitted on the PSSCH channel. The SCI also includes QoS-related parameters corresponding to the transport block, such as priority, latency, reliability, etc. Since these parameters can be used by other UEs to detect channel occupancy, they need to be carried in the SCI.

[0069] When generating SCI, the UE needs to set the value of the field corresponding to these Qos-related parameters. One setting method may be that the UE, based on the method described in Example 1, sets the value of the Qos parameter carried in the SCI to the value of the Qos parameter of the corresponding TB after determining the value of the Qos parameter corresponding to the TB. Here, the TB corresponding to the SCI refers to the TB transmitted on the PSSCH scheduled by the SCI. It can also be set based on the value of the Qos parameter corresponding to the corresponding TB.

[0070] Example 3

[0071] Embodiment 3 of the present invention is described below. The difference between Embodiment 3 and Embodiment 2 is that the value of the Qos parameter corresponding to the MAC PDU is not a fixed value.

[0072] Taking priority as an example, when the UE receives a CSI request, the UE may generate a MAC PDU that does not include a MAC SDU but only includes a MAC header and padding bits, or only includes a MAC header, MAC CE and / or padding bits. The UE may carry the generated and requested CSI report (referred to as CSI) in a puncher-coded manner on the PSSCH used to transmit the MAC PDU.

[0073] Since the CSI request can be carried in the SCI, the SCI also indicates a PSSCH transmission, and the MAC PDU is carried on the PSSCH. According to the method in Example 1, in the SCI carrying the CSI request, the QoS parameters contained therein, such as the priority value, can be determined by the priority value corresponding to the MAC PDU transmitted on the scheduled PSSCH, and can be set equal to the priority value corresponding to the MAC PDU. For example, if the priority value corresponding to the MAC PDU is X, then the value of the priority field contained in the SCI carrying the CSI request can be set to X.

[0074] Then the CSI report generated in response to the CSI request, when it is carried on the PSSCH for transmission,

[0075] -If the MAC PDU transmitted on this PSSCH does not contain a MAC SDU, then the priority value corresponding to the MAC PDU can be considered to be X, and the priority value in the SCI for scheduling the PSSCH carrying the MAC PDU transmission is set to X. Scheduling refers to indicating the resource information for PSSCH transmission in the SCI.

[0076] -If the MAC PDU transmitted on this PSSCH contains a MAC SDU, then the method described in Example 1 can be used to determine the priority value corresponding to the MAC PDU based on the MAC SDU, and then determine the priority value of the TB carrying the MAC PDU, and set the priority in the SCI of the PSSCH that schedules the transmission of the MAC PDU to be the same as the priority value of the transmission block.

[0077] In one case, the indication information of the CSI request is not directly carried in the SCI, but the information of the existence of the CSI RS is indicated in the SCI. In this case, the CSI request may be implicitly indicated. When the UE receives the SCI indicating the existence of the CSI RS, it can be considered as a CSI request, thereby generating a corresponding CSI report. In this case, it can be considered that the value X of the priority field indicated by the SCI carrying the information of the existence of the CSI RS can be used as the value of the priority field in the SCI that schedules the PSSCH carrying the CSI report, that is, it is set to X.

[0078] Example 4

[0079] Embodiment 4 of the present invention is described below. In embodiment 4, the UE may transmit a CSI report on a PSSCH channel. The SCI of the PSSCH scheduled to carry the CSI report may carry an indication indicating that the CSI report is carried on the scheduled PSSCH. In this case, the PSSCH channel may not carry a MAC PDU or a TB.

[0080] When the SCI carries an indication indicating that the scheduled PSSCH carries a CSI report, the UE can set the value of the Qos parameter in the SCI to a fixed value, or set the value of the Qos parameter based on a certain parameter. The specific setting method is as described in Example 1.

[0081] Another implementation method of the above scheme may be: when the SCI carries an indication indicating that the scheduled PSSCH carries a CSI report, the UE may not include / omit the information of the Qos parameter in the SCI; when other UEs read / receive an SCI, the SCI carries an indication of the CSI report, then other UEs may consider that the value of the corresponding Qos parameter is a fixed value, or the method of obtaining the specific setting based on a certain parameter is as described in Embodiment 1. For example, the value of the priority is always 0, the value of the delay is always 1, and the value of the reliability is always 8, etc.

[0082] Example 5

[0083] Embodiment 5 of the present invention is described below. The difference between Embodiment 5 and Embodiment 4 is that the UE can transmit CSI RS (CSI reference signal) on the PSSCH channel. In this case, the SCI that schedules the PSSCH will carry an indication that the scheduled PSSCH carries CSI RS. In this case, the PSSCH channel may not carry MAC PDU or TB.

[0084] When the SCI carries an indication indicating that the scheduled PSSCH carries the CSI RS, the UE can set the value of the Qos parameter in the SCI to a fixed value, or set the value of the Qos parameter to a fixed value based on a certain parameter. The specific setting method is as described in Example 1.

[0085] Another implementation method of the above scheme can be

[0086] When the SCI carries an indication indicating that the scheduled PSSCH carries the CSI RS, the UE may not include / omit the information of the Qos parameter in the SCI; when other UEs read / receive an SCI, the SCI carries the indication of the CSI RS, then other UEs may consider that the value of the corresponding Qos parameter is a fixed value, or can be obtained based on a certain parameter, and the specific setting method is as described in Example 1. For example, the value of the priority is always 0, the value of the delay is always 1, and the value of the reliability is always 8.

[0087] Example 6

[0088] As Embodiment 6 of the present invention, Embodiment 2 and Embodiment 4 may be used in combination.

[0089] When the SCI indicates that the CSI-report is carried on the PSSCH channel, and the scheduled PSSCH channel does not carry the MAC PDU / TB, Embodiment 4 may be adopted.

[0090] When the PSSCH channel indicated by the SCI carries the CSI report, and the PSSCH channel scheduled by it carries the MAC PDU, embodiment 2 may be adopted.

[0091] Example 7

[0092] As Embodiment 7 of the present invention, Embodiment 2 and Embodiment 5 may be used in combination.

[0093] When the SCI indicates that the PSSCH channel carries the CSI-RS, and the PSSCH channel scheduled by it does not carry the MAC PDU / TB, Embodiment 5 may be adopted.

[0094] When the SCI indicates that the PSSCH channel carries the CSI-RS, and the PSSCH channel scheduled by it carries the MAC PDU / TB, Example 2 may be adopted.

[0095] Example 8

[0096] The following is an explanation of Example 8 of the present invention. In Example 1, it is mentioned how to determine which type of data packet needs to be sent first when the resources used to send air interface data packets conflict with the resources used to send V2X data packets. Example 8 introduces a conflict resolution method when the above-mentioned conflict occurs.

[0097] The resources used to send air interface data packets mainly refer to PUCCH and PUSCH, and the resources used to send V2X data packets mainly refer to PSSCH. Therefore, it can be considered that when the transmission of PUSCH / PUCCH conflicts with the transmission of PSSCH, how to determine which channel to send first should be considered.

[0098] When a TB is carried on the PSSCH and the TB carries a MAC PDU, the priority of the MAC PDU carried by it can be determined by the method of Example 1, and it is considered that the priority corresponds to (or is equal to) the priority of the PSSCH transmission. Since the MAC PDU may not carry a MAC SDU, that is, it does not carry service-related data, then at this time, in order to determine which channel needs to be sent first, it is necessary to clarify the priority corresponding to the MAC PDU.

[0099] In Embodiment 1 and Embodiment 3, a method for determining the priority of a MAC PDU that does not include a MAC SDU is provided, which can be applied here. Based on this method, after determining the priority of the MAC PDU, the UE can compare the priority of the MAC PDU with the priority threshold value. If it is higher (or lower) than the threshold value, the MAC PDU is sent first. If it is lower (or higher) than the threshold value, the data packet of the air interface is sent first.

[0100] Since the transmission on the PSSCH may not carry a TB, when a conflict occurs, the UE may determine the priority of the PSSCH transmission according to the method of Embodiment 4 or 5, that is, the priority of the SCI determined by the method of Embodiment 4 or 5 may be used as the priority of the PSSCH transmission scheduled by the SCI. Furthermore, the UE may compare the determined priority with the priority threshold value, and if it is higher (or lower) than the threshold value, the PSSCH is sent first, and if it is lower (or higher) than the threshold value, the data packet (PUSCH / PUCCH) of the air interface is sent first.
