Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a resource indication, acquisition method, and communication device. Background Technology

[0002] To improve transmission reliability, New Radio (NR) systems can introduce a mechanism for cooperation between UEs. This means that the receiver indicates or recommends resources, and the user equipment (UE, also known as the terminal) transmitting data transmits data on the resources indicated or recommended by its corresponding receiver UE. This helps to alleviate the problems of low transmission reliability caused by half-duplex issues and hidden node issues.

When the receiving UE makes resource recommendations or indications, resource conflicts or channel congestion may occur, making it difficult to guarantee the reliability of transmission. This will affect system performance and reduce resource utilization. Summary of the Invention

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used with the systems and radio technologies mentioned above, as well as with other systems and radio technologies. However, the following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description, although these technologies can also be applied to applications other than NR systems, such as 6th generation (6G) radio systems. th Generation 6G communication system.

[0028] To enable those skilled in the art to better understand the embodiments of this application, the following description is provided first.

[0029] The following explains Sidelink resource allocation, CR, and CBR.

[0030] 1. Sidelink resource allocation.

[0031] NR V2X defines two resource allocation modes: mode 1, where resources are allocated by the base station; and mode 2, where the UE decides which resources to use for transmission. Resource information may come from broadcast messages from the base station or pre-configured information. If the UE is within range of the base station and has an RRC connection with it, it can operate in either mode 1 or mode 2. If the UE is within range of the base station but does not have an RRC connection, it can only operate in mode 2. If the UE is outside range of the base station, it can only operate in mode 2 and perform V2X transmissions according to the pre-configured information.

[0032] For mode 2, the specific operation is as follows: 1) After resource selection is triggered, the transmitting end (TX) UE first determines the resource selection window. The lower boundary of the resource selection window is at time T1 after the resource selection is triggered, and the upper boundary is at time T2 after the trigger. T2 is the value selected by the UE within the PDB (packet delay budget) of its transport block (TB) transmission. T2 is no earlier than T1. 2) Before resource selection, the UE needs to determine the candidate resource set. It compares the reference signal receiving power (RSRP) measured on the resources within the resource selection window with the corresponding RSRP threshold. If the RSRP is lower than the RSRP threshold, then the resource can be included in the candidate resource set. 3) After the resource set is determined, the UE randomly selects a transmission resource from the candidate resource set. In addition, the UE can reserve transmission resources for subsequent transmissions during this transmission.

[0033] 2. CR.

[0034] The CR (Content Requirement) is calculated based on the priority of the UE's transmission services. Each service priority corresponds to a CR value. The method is as follows: at the current time n, if the priority of the service to be transmitted by the sender is q, then the amount of resources A allocated by the UE in the transmission resource pool for service transmission with priority q within the time period [na, n-1] needs to be counted, and the amount of resources B reserved by the UE in the transmission resource pool for service transmission with priority q within the time period [n, n+b] needs to be counted. The total amount of resources in the transmission resource pool within the time period [na, n+b] is C. Therefore, the CR for priority q is (A+B) / C, where a+b+1 equals 1000 or 1000*2. u There are 1 physical slot. The frequency domain granularity of the resource is a sub-band, and the time domain granularity is a slot.

[0035] When reserving resources, assuming the priority of the service that needs to be transmitted is q, the restrictions on CR are as follows:

[0036] ∑ i≥q CR(i)≤CR Limit (q);

[0037] Among them, CR Limit (q) is configured by higher-level parameters. This limit means that the sum of the CRs for services with priority less than or equal to q must not exceed the CR limit for services with priority q. This limit is used for congestion control on sidelinks.

[0038] 3. CBR.

[0039] CBR is used to measure the channel busy characteristics of the entire system. Specifically, it is calculated as follows: at the current time n, within the time period [na, n-1], let A be the number of resources in the resource pool whose RSSI exceeds the threshold T, and let B be the total number of resources in the resource pool. Then, CBR is A / B, where a is 100 or 100*2. u There are 1 physical slot. The frequency domain granularity of the resource is a sub-band, and the time domain granularity is a slot.

[0040] In the resource allocation mode (mode 2) chosen autonomously by the User Equipment (UE) on a New Radio (NR) sidelink, the prerequisite for the UE to reserve transmission resources each time is that the proportion of resources reserved by the UE within a certain time window to the total resources within that time window must meet a certain threshold requirement. Currently, to improve transmission reliability, it is desirable to introduce a receiver-indicated or recommended resource allocation method, where the transmitter transmits data on the resources indicated or recommended by the receiver. This helps alleviate the problems of low transmission reliability caused by half-duplex issues and hidden node issues. However, after introducing this mechanism, the relevant CR and CBR calculation methods are no longer applicable. Resource conflicts or channel congestion may occur during resource recommendation or indication, making it difficult to guarantee transmission reliability.

[0041] This application provides a resource indication method applied to a first communication device, which may be a first terminal or a control node. The method includes:

[0042] Step 101: Based on the transmission information of the second communication device or the transmission information of the first communication device, indicate a first resource to the second communication device; wherein, the first resource is used by the second communication device to determine transmission resources.

[0043] The second communication device can be a second terminal or a control node. Optionally, the second terminal is a data sending UE, and the first terminal is a data receiving UE.

[0044] Optionally, the first communication device can indicate the first resource to the second communication device via auxiliary information. The second communication device can then select or reserve the resource based on the location information of the first resource carried in the auxiliary information, choosing or reserving the resource for transmission or reception. In addition to the location information of the first resource, the auxiliary information can also carry information such as the validity period of the first resource, the periodicity of the first resource, and the usage information of the first resource (fully available, partially available, or unavailable), etc. This information can also serve as the basis for the second communication device to select or reserve the resource.

[0045] The resource indication method of this application embodiment can reasonably indicate the first resource to the second communication device based on the transmission information of the second communication device or the transmission information of the first communication device, ensuring the fairness and effectiveness of resource indication, and thus effectively solving the problems of resource conflict or channel congestion in the scenario of UE cooperation.

[0049] The triggering information is used to trigger the first communication device to transmit auxiliary information, indicating or recommending suitable resources to the second communication device to enhance transmission reliability. The triggering information may carry transmission resources indicating auxiliary information, and the transmission of the triggering information also consumes system resources. Regarding the triggering information itself, if it is carried in the PSSCH, the resources occupied by the triggering information sent by the sending end are calculated within the sending end's channel occupancy rate and updated and calculated on the second communication device side. As for the transmission resources of the auxiliary information carried in the triggering information, based on the actual usage of these resources by the second communication device, the actually used resources are included in the channel occupancy rate of the services transmitted by the second communication device; or, all transmission resources of the auxiliary information in the triggering information are included in the channel occupancy rate of the services transmitted by the second communication device; or, the transmission resources of the auxiliary information carried in the triggering information also need to meet a first rule, namely, the number of resources indicated by at least one communication device in the triggering information within the first moment or first time period needs to be less than a first threshold, or the proportion of the number of resources indicated by at least one communication device in the triggering information to the total resources within the first moment or first time period needs to be less than a first threshold.
