Description

Resource set determining method and device, chip and module equipment
Technical Field

Background
The resource allocation of the new air interface side link user equipment (new radiosidelinkuser equipment, NRSidelinkUE) supports both base station centralized scheduling (mode 1) and autonomous resource awareness (mode 2). In mode2, the UE acquires resources used for transmission through autonomous resource awareness. In order to meet some UEs with high power saving requirements, partial resource awareness is supported under mode 2. The partial resource awareness is divided into two kinds of periodic partial awareness (PBPS-based partial sensing) and continuous partial awareness (contiguous partial sensing, CPS). The initial candidate resource set of CPS can be determined according to the resource selection results of other PBPS and CPS processes, and then the initial candidate resource set is subjected to resource elimination through resource awareness to form a final available candidate resource set. However, in practice, it is found that the UE may not obtain enough initial candidate resource sets due to too few resource selection results in other PBPS and CPS procedures, which may result in poor quality of candidate resources in the final available candidate resource sets, and reduce the reliability of side link transmission.

The embodiment of the application does not limit the specific technology and the specific device form adopted by the network device.
The resource allocation of the side link supports both base station centralized scheduling (mode 1) and autonomous resource awareness (mode 2). Mode1 resource allocation is also known as base station scheduling resource Mode, i.e. the communication resources of the side link are all allocated by the base station. And under mode2, the terminal equipment autonomously performs resource allocation based on resource awareness. In order to meet the requirements of some terminal equipment with higher power saving requirements, partial resource sensing is supported under mode 2. The partial resource awareness is divided into two kinds of periodic partial awareness (PBPS-based partial sensing) and continuous partial awareness (contiguous partial sensing, CPS). Embodiments of the present application relate generally to CPS. The process of CPS is described in detail below:
the service types of the side link are classified into periodic and aperiodic service types, and CPS is supported under both service types. For example, taking aperiodic service as an example, fig. 2 is a schematic diagram of a CPS. As shown in fig. 2, the service arrives at time n, which is the resource selection trigger time. For aperiodic traffic, time n cannot be predicted in advance, so the resource-aware window is located after time n. The terminal device determines an initial set of candidate resources in a resource selection window after time n. The candidate resources and the initial candidate resources in the embodiments of the present application may be radio frames (radio frames), subframes (subframes), mini subframes, slots (slots), mini-slots (mini-slots), or orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbols, etc. The resource awareness window is located before the arrival of the first candidate resource in the resource selection window. For example, the terminal device may determine the initial candidate set of resources based on the resource selection results of other PBPS and CPS procedures. The terminal device makes other PBPS and CPS because of the transmission of other services, and determines the final available candidate resources after the PBPS and CPS procedure is finished. The terminal device may take these available candidate resources as initial candidate resources for the current CPS. For example, as shown in fig. 2, the terminal device determines that the initial candidate resource set includes 3 initial candidate resources, which are slot n1, slot n2, and slot n3, respectively. And then the terminal equipment performs sustainable resource sensing in the resource sensing window so as to sense the occupation condition of other terminal equipment on the resources in the initial candidate resource set. After the end of the resource sensing window, the terminal device performs resource elimination on the resources occupied by other terminal devices in the initial candidate resource set, and finally the set formed by the remaining available candidate resources is the candidate resource set. And the terminal equipment selects the resources in the candidate resource set to carry out side chain transmission.
In order to improve reliability of side link transmission, the application provides a resource set determining method, a device, a chip and module equipment. The method, the device, the chip and the module device for determining the resource set provided by the embodiment of the application are further described in detail below.
Fig. 3 is a flowchart of a method for determining a resource set according to an embodiment of the present application. As shown in fig. 3, the resource set determination method includes the following steps 301 to 303. The method execution body shown in fig. 3 may be a terminal device. Alternatively, the method execution body shown in fig. 3 may be a chip in the terminal device. Fig. 3 illustrates an example of a method performed by a terminal device.
301. The terminal device determines whether the length of the resource-aware window is greater than a first threshold.
Wherein the first threshold may be configured by the network device. I.e. the terminal device may also receive first configuration information from the network device, the first configuration information being used to configure the first threshold. Alternatively, the first configuration information may be located in higher layer signaling. For example, the higher layer signaling may be radio resource control (radio resource control, RRC) signaling. The first threshold value can be configured more flexibly by configuring the first threshold value through the network equipment.
Alternatively, the first threshold may be predefined by the protocol. The first threshold value is predefined through the protocol, so that configuration overhead is saved.
Wherein the first threshold may be a smaller value.
302. If the length of the resource sensing window is greater than the first threshold, the terminal device determines whether the number of initial candidate resources in the initial candidate resource set is greater than the second threshold.
In the embodiment of the present application, the initial candidate resource set may be determined based on the resource selection results of other PBPS and CPS procedures.
In the embodiment of the present application, the second threshold may be configured by the network device. I.e. the terminal device may also receive second configuration information from the network device, the second configuration information being used to configure the second threshold. Alternatively, the second configuration information may be located in higher layer signaling. For example, the higher layer signaling may be RRC signaling. The second threshold value can be configured more flexibly by configuring the second threshold value through the network device.
Alternatively, the first configuration information and the second configuration information may be located in the same RRC signaling, or the first configuration information and the second configuration information may be located in different RRC signaling, which is not limited in the embodiment of the present application.
Alternatively, the second threshold may be protocol predefined. The second threshold value is predefined through the protocol, so that configuration overhead is saved.
Wherein the second threshold may be a smaller value.
303. If the number of the initial candidate resources is smaller than or equal to the second threshold value, the terminal equipment adds candidate resources into the initial candidate resource set.
In the embodiment of the present application, the terminal device may specifically add one or more resources in the resource selection window to the initial candidate resource set. The terminal device may add any one or more resources in the resource selection window to the initial candidate set of resources.
For example, assume that the resource selection window includes time slots n-n (n+10), and the second threshold is 6. If the initial candidate resource set determined by the terminal device based on the resource selection results of other PBPS and CPS procedures includes 3 slots, slot n, slot (n+1) and slot (n+2), respectively. The terminal device adds one or more time slots in the resource selection window to the initial candidate resource set.
In one possible implementation, the specific implementation of adding the candidate resource to the initial candidate resource set by the terminal device is: and the terminal equipment adds candidate resources into the initial candidate resource set, so that the number of the initial candidate resources in the initial candidate resource set is larger than a second threshold value. Therefore, sufficient candidate resources in the initial candidate resource set can be ensured, the number of candidate resources with better quality in the final available candidate resource set can be increased, and the reliability of side link transmission is improved.
For example, assume that the initial candidate resource set includes 3 slots, slot n, slot (n+1), and slot (n+2), respectively, with a second threshold of 6. The terminal device adds at least 4 time slots in the resource selection window to the initial candidate resource set.
In another possible implementation, the terminal device may add the candidate resources to the initial candidate resource set, or may not make the number of initial candidate resources in the initial candidate resource set greater than the second threshold.
For example, assuming that the initial candidate resource set includes 3 slots, slot n, slot (n+1) and slot (n+2), respectively, and assuming that the second threshold is 6, the terminal device adds only 1 or 2 slots or 3 slots in the resource selection window to the initial candidate resource set.
It can be seen that in the method described in fig. 3, the terminal device may determine whether the number of initial candidate resources in the initial candidate resource set is greater than the second threshold when the length of the resource awareness window is greater than the first threshold, and add the candidate resources to the initial candidate resource set when the number of initial candidate resources is less than or equal to the second threshold. Therefore, based on the method described in fig. 3, the method is beneficial to ensuring sufficient initial candidate resources in the initial candidate resource set, so that the number of candidate resources with better quality in the final available candidate resource set can be increased, and the reliability of side chain transmission is improved. And, by determining whether the number of initial candidate resources in the initial candidate resource set is greater than the second threshold when the length of the resource sensing window is greater than the first threshold, instead of directly executing the step of determining whether the number of initial candidate resources in the initial candidate resource set is greater than the second threshold, power consumption of the terminal device is advantageously saved.
Fig. 4 is a flowchart of a method for determining a resource set according to an embodiment of the present application. As shown in fig. 4, the resource set determination method includes the following steps 401 to 404. The method execution body shown in fig. 4 may be a terminal device. Alternatively, the method execution body shown in fig. 4 may be a chip in the terminal device. Fig. 4 illustrates an example of a method of a terminal device.
401. The terminal device determines whether the length of the resource-aware window is greater than a first threshold.
402. If the length of the resource sensing window is greater than the first threshold, the terminal device determines whether the number of initial candidate resources in the initial candidate resource set is greater than the second threshold.
403. If the number of the initial candidate resources is smaller than or equal to the second threshold value, the terminal equipment adds candidate resources into the initial candidate resource set.
The specific embodiments of steps 401 to 403 can be referred to the specific embodiments of steps 301 to 303, and are not described herein.
404. If the length of the resource awareness window is less than or equal to the first threshold, then: the terminal equipment randomly selects resources for side link transmission from the resource selection window; or the terminal equipment determines whether the initial candidate resource number is larger than a second threshold value, and adds the candidate resource to the initial candidate resource set when the initial candidate resource number is smaller than or equal to the second threshold value.
That is, when the terminal device determines that the length of the resource-aware window is less than or equal to the first threshold, the terminal device may select to perform mode 1 or mode 2. Mode 1 is for a terminal device to randomly select resources for side link transmission from a resource selection window. Mode 2 determines, for the terminal device, whether the initial number of candidate resources is greater than a second threshold, and adds candidate resources to the initial set of candidate resources when the initial number of candidate resources is less than or equal to the second threshold. The mode of the terminal device to select specifically is implemented by the terminal device, and the embodiment of the application is not limited.
In mode 1, the terminal device does not perform resource sensing, and directly randomly selects resources for side link transmission from the resource selection window, which is beneficial to reducing power consumption of the terminal device.
In mode 2, the terminal device needs to perform resource sensing, and excludes resources occupied by other terminal devices in the initial candidate resource set, so that the problem of resource collision can be avoided. In the mode 2, enough candidate resources in the initial candidate resource set can be ensured, and the reliability of the side link transmission can be improved.
In one possible implementation, the terminal device may randomly select resources for side link transmission from the resource selection window when the power of the terminal device is less than the third threshold. Alternatively, the terminal device may randomly select resources for side link transmission from the resource selection window when the power saving mode is turned on.
In one possible implementation, the terminal device may select implementation 2 when the reliability requirement of the transmitted service is greater than a fourth threshold.
In one possible implementation, the adding, by the terminal device, a candidate resource to the initial candidate resource set includes: and adding candidate resources into the initial candidate resource set, so that the number of the initial candidate resources in the initial candidate resource set is larger than a second threshold value. Therefore, sufficient candidate resources in the initial candidate resource set can be ensured, the number of candidate resources with better quality in the final available candidate resource set can be increased, and the reliability of side link transmission is improved.
In another possible implementation, the terminal device may add the candidate resources to the initial candidate resource set, or may not make the number of initial candidate resources in the initial candidate resource set greater than the second threshold.
Optionally, the specific implementation manner of randomly selecting the resource for side link transmission from the resource selection window by the terminal device is as follows: and when the number of the resources in the resource selection window is smaller than or equal to the second threshold value, the terminal equipment randomly selects the resources for the side link transmission from the resource selection window. When the number of resources in the resource selection window is smaller than the second threshold, the terminal equipment cannot add candidate resources to the initial candidate resource set, so that the number of the initial candidate resources in the initial candidate resource set is larger than the second threshold. Therefore, when the number of resources in the resource selection window is smaller than the second threshold, the terminal device can select the execution mode 1, so that the error reporting of the terminal device can be avoided.
In one possible implementation, the terminal device randomly selects resources for side link transmission from a resource selection window, including: the terminal device randomly selects resources for side link transmission from the initial set of candidate resources in the resource selection window. The initial candidate resource set may be determined based on the perceived results of other PBPS and CPS. Meaning that the resources in the initial candidate set of resources are perceived as available resources in other CPS and PBPS. The random selection of resources for side link transmission from the initial candidate set of resources is therefore more reliable than the random selection of resources for side link transmission in the resource selection window.
Alternatively, the terminal device randomly selects a resource for side link transmission from all the resources in the resource selection window.
