In order to make the description of the embodiments of the present invention more clear, the following description and description are given in conjunction with the preferred embodiments.

The preferred embodiment of the present invention provides a method and a device for processing pre-occupied resources to preferentially ensure the use of communication resources by emergency services or high-level user equipment.

As shown in FIG. 3, the solution provided by the preferred embodiment of the present invention includes the following steps:

Step S302: The user equipment is classified into a high priority user and a low priority user according to the priority classification.

Step S304, if the high-priority user needs to occupy resources in the nth communication cycle, the announcement signal is broadcasted on the PSCCH of the n-m period, indicating that the pre-occupied resource is used;

Step S306, after the low priority user correctly receives the notification signal, the resource is selected according to the policy indicated by the pre-configuration policy or the notification signal. Wherein n is an integer not less than m; and m is an integer.

The preferred embodiment of the present invention can be applied to a communication system in which a central node or a central node does not participate in communication resource allocation control, and priority is given to ensuring communication quality of high priority users.

In step S302, the user participating in the communication (ie, the UE) may be classified into multiple priority levels according to the priority classification of the transmitted application layer data packet or the attribute of the UE, for example, 1 to 8 levels, indicating that priority is given. The level increases in turn. The above multiple priority levels can be further divided into two categories: high priority and low priority.

The high-priority user has a higher resource occupation priority and can send the resource pre-occupation notification information; the low-priority user has a lower resource occupation priority, cannot send the resource pre-occupation notification information, and the low-priority user needs to receive the information. And detecting resource occupancy notification information sent by high-priority users (high-priority users can detect or not detect other highs) The resource occupation notification information sent by the priority user), if the advertisement information is detected, it should select the resource according to the policy indicated by the pre-configured policy or the announcement information. The low priority may be further divided into a 2a priority, a 2b priority, and the like according to different resource allocation policies.

In step S304, the high priority UE broadcasts the advertisement information on the specific side control information (Sidelink Control Information, SCI for short), and informs the resource preemption of the nth communication period of the low priority UE.

In step S306, the low priority UE receives and detects the advertisement information, and adjusts the resource occupation according to the resource occupation policy indicated by the pre-configuration or advertisement information, such as releasing or discarding the occupied resource, or changing the resource selection probability, or only limited. Select resources on some of the resource pools.

Optionally, the specific SCI resource refers to an SCI resource used for sending resource pre-occupation notification information at a specific location in the PSSCH resource pool. The resource location can be pre-configured or configured by a central node or higher layer. For example, the resource number is 0 or the second to last SCI resource, or other specific SCI resource combination. This type of SCI resource is only used for high priority UE broadcast announcement information, and other grades of UE do not use this type of SCI resource.

Optionally, the advertisement information may be indicated by a specific value of one domain in the SCI content or a specific value combination of several domains; or a new SCI format is defined, where one or more domains are included to indicate the advertisement information.

Optionally, the resource selection policy of the low-priority UE is to use the corresponding resource occupation policy according to its own priority level after receiving the notification information correctly, such as abandoning the occupied resource, or changing the resource occupation probability or changing in the resource pool. The range of resources to choose from.

The abandonment of the resource means that the low-priority UE abandons the resource selection in the nth communication period and correctly discards the resource for the high-priority UE after receiving the notification information correctly.

Wherein, changing the resource occupation probability means that the low priority UE selects resources according to the probability corresponding to its priority on its selectable resource pool. The probability range is 0 to 1. A value of 0 indicates that the priority UE renounces resource selection on its selectable resource pool.

The change of the resource selection range means that the low priority UE changes the selectable resource pool size, and the priority UE can only select resources in the resource area within a certain range corresponding to or configured by the priority. The qualified resource area is a subset of the original resource pool.

Optionally, the resource pool refers to a set of time domain and frequency domain radio resource units that are available for the UE to send signals. It mainly includes a physical side row control channel (PSCCH) resource pool and a physical side row shared channel (PSSCH) resource pool. The PSCCH resource pool is a set of radio resource units used by the UE to send SCI, and the PSSCH resource pool is a set of radio resource units used by the UE to transmit data.

The technical solutions of the present invention are described and illustrated below in conjunction with specific embodiments.

Preferred embodiment 1

There are two ways to announce the SCI format of a message:

Method 1: Use the 3GPP protocol R12 version definition.

The SCI format of the announcement information is still defined in the R12 version of the 3GPP (3rd Generation Partnership Project) protocol. Here, defining a specific value of one of the domains or a combination of specific values of several domains indicates that the notification information is true, such as the 'Modulation and coding scheme (MCS)' field using one of the reserved values (29, 30, 31), indicating the notification signal True, or use the reserved value of the 'Time resource pattern' field, such as the reserved value 0 (N _TRP , the length of the bit indicated by the Time resource pattern) when N _TRP = 7, indicating that the announcement signal is true, indicating that the high priority UE The resource of the nth communication period is pre-occupied, and the low priority UE should use the policy corresponding to its priority to perform resource selection, such as abandoning the occupied resource, or changing the resource occupation probability or changing the resource selection range in the resource pool.

An example: the 'Modulation and coding scheme (MCS)' field value 29 indicates that the advertisement signal is true, and the time domain and frequency domain resources indicated by other fields of the announcement signal SCI indicate that the resources will be high priority during the nth communication cycle. The UE is occupied, and the low priority UE can no longer be used.

Method 2: Define a new SCI format.

Define a new SCI format that includes a combination of one or several of the following fields:

The pre-occupied identification field indicates whether the high priority UE occupies resources in the nth communication cycle.

The transmission probability field indicates the transmission probability of other priority UEs. The transmission probability of different priority UEs may be indicated for multiple values.

The frequency domain resource indication field (FR) indicates a frequency domain resource area or only a selectable frequency domain resource area that other priority UEs should avoid.

The time domain resource indication field (TR) indicates a time domain resource area or only a selectable time domain resource area that other priority UEs should avoid.

The priority level indication field (PR) indicates the priority level information or the priority index indication of the transmitting UE.

As shown in FIG. 4, an example is as follows: the pre-occupation identifier is 1, and the transmission probability is p1, p2. The frequency domain resource indicates FR, indicating that other priority UEs can only be selected within the resource area indicated by the FR. The time domain resource TR indicates that other priority UEs can only be selected in the time domain area indicated by the TR, and the priority level is P.

The above SCI content indicates that, in the nth communication cycle, the UE whose priority level is P pre-occupied resources, and the UE whose priority level is lower than P can only select resources in the resource area indicated by FR and TR, and the UE of the 2a priority The transmission probability is p1, and the transmission probability of the 2b priority UE is p2. The priority 2a and the priority 2b priorities are lower than the priority P or the notification information transmission priority threshold.

Preferred embodiment two

The location of the specific SCI resource of the broadcast announcement information in the PSCCH resource pool may be pre-configured for the user equipment, or configured by the central node, or indicated by resource pool configuration signaling or communication user group establishment configuration signaling.

For example, the specific SCI resource of the advertisement information is the first SCI resource on the PSCCH resource pool, wherein the SCI format is defined in the preferred embodiment 1. The first SCI resource location in the example, such as the resource location of sequence number 1 in Figure 5:

For example, the specific PSCCH resource used for the advertisement information transmission is not limited to the first SCI resource on the PSCCH resource pool, and the first SCI resource and the second last SCI resource on the PSCCH resource pool may be defined for broadcasting announcement information, or defined. The resource sequence number N satisfies a partial PSCCH resource with N mod Nt of 2m or 2m+1, where Nt is the number of time domain subframes of the PSCCH resource pool, and m is an integer greater than or equal to zero. The SCI resources of

sequence numbers

1 and 15 in Figure 6.

Example 3: A specific PSCCH resource for an SCI for advertising information transmission may define a dedicated PSCCH resource. One end of the low frequency or high frequency, such as defining a PSCCH resource pool, reserves a continuous time-frequency resource for the transmission of the announcement information. The announcement information in FIG. 7 specifies a specific PSCCH resource area. The transmitting resource may select one or more of the specific PSCCH resource regions.

Optionally, if the high priority UE needs to broadcast the advertisement information to pre-occupy the resources of the nth period, first select one or more of the notification information SCI resource locations defined above for use as the transmission of the advertisement information. However, if there is still data to be sent in the current period, that is, the SCI of the data scheduling needs to be sent, it is necessary to ensure that the selected announcement information SCI and the data scheduling SCI are not in the same subframe. If the same subframe position is selected, then the data scheduling SCI resource is considered to be reselected until at least one selected available announcement information SCI is not in the same time domain subframe as the data scheduling SCI.

Preferred embodiment three

The low-priority UE receives and parses the advertised information at the specific location of the resource pre-occupation notification information SCI. If the resource pre-occupation notification information is obtained, the resource-receiving manner indicated by the pre-configured resource processing mode or the notification information SCI is performed. Resource occupancy processing.

If the resource location occupied by the current communication cycle of the low priority UE is in the same time domain subframe as the specific location of the reception announcement information SCI, the user equipment of the single transceiver receiver is preferentially guaranteed to send its own data, and only does not send data itself. Receive announcement information and other signals on the time domain subframe.

The pre-configured resource processing mode is a configuration in which the UE device is initially solidified, or a resource processing related configuration has been obtained through the configuration process. If there is a high priority UE resource pre-occupation signal, the pre-configured transmission probability corresponding to the UE priority level, or a predefined selectable resource range, and the like.

The resource processing mode indicated by the notification information SCI is that the low priority UE obtains the SCI content carrying the advertisement information, obtains the transmission probability of the subsequent occupied resources, the selectable resource range, and the like, and then performs corresponding processing according to the indication.

Optionally, the low-priority UE participates in selecting and transmitting data with the corresponding probability value on the selectable resource according to the obtained or pre-configured resource occupation related configuration parameter.

An example: a pre-configured low-priority UE quits at the nth after receiving the resource occupation signal sent by the high-priority UE. The resource selection of the communication cycle is occupied.

In another example, the low-priority UE parses the notification information SCI, where the transmission probability in the SCI parameter is p1, the optional frequency domain resource is FR, and the optional time domain resource is TR, then the UE is in the nth communication cycle, with probability P1, autonomously selecting resources for data transmission on selectable resources.

It will be apparent to those skilled in the art that the various modules or steps of the present invention described above can be implemented by a general-purpose computing device that can be centralized on a single computing device or distributed across a network of multiple computing devices. Alternatively, they may be implemented by program code executable by the computing device such that they may be stored in the storage device by the computing device and, in some cases, may be different from the order herein. The steps shown or described are performed, or they are separately fabricated into individual integrated circuit modules, or a plurality of modules or steps thereof are fabricated as a single integrated circuit module. Thus, the invention is not limited to any specific combination of hardware and software.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention, and various modifications and changes can be made to the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
