Embodiment 1

[0129] In this embodiment, for multiple resources associated with different TTIs, after determining the priority of each LCH through the LCP, resources can be matched for each LCH in the order of LCH priorities from high to low, and transmission can be performed on the matched resources. LCH data.

[0130] In Embodiment 1, for multiple resources associated with different TTIs, the resource allocation process is specifically as follows:

[0131] 1. The first round of resource allocation

[0132] (1) Allocate resources for the highest priority LCH first: according to the maximum transmission interval (Maximun TTI duration) of the highest priority LCH, determine the resources associated with the maximum TTI less than or equal to the maximum transmission interval as the LCH matching resource, and transmit the data of the LCH on the resource matching the LCH.

[0133] (2) Allocate resources for the LCH of the next priority: if the multiple resources are left, then according to th...

Embodiment 2

[0156] In this embodiment, when resources are allocated to each LCH according to the order of LCH priorities from high to low, if the resources matched by the LCH just meet the attribute requirements of the LCH, the LCH data. If the resource matched by the LCH exceeds the attribute requirements of the LCH, record the LCH in the sub-priority queue corresponding to the uplink authorization resource matched by the LCH, and wait for the next round of resource allocation.

[0157] That is to say, when performing resource allocation, in addition to the priority of the LCH, the attribute requirements of the LCH (such as the maximum transmission interval) are further considered, and the actual resource allocation sequence of the LCH can be adaptively adjusted according to the attribute requirements of the LCH, further To avoid "oversatisfaction" of a certain LCH (some) and cause LCHs with high attribute requirements not to obtain resources to transmit data.

[0158] It can be underst...

Embodiment 3

[0201] In this embodiment, the resource-associated numerology (such as TTI) can be configured with a priority. When resource allocation is performed, resources associated with different numerology may be allocated to one or more LCHs respectively matched by the respective resources according to the order of numerology priorities from high to low. Then, for resources associated with a numerology, resources associated with the numerology may be allocated to matching LCHs according to the order of LCH priorities from high to low. Here, the resources associated with the numerology at least meet the attribute requirements of the matched LCH.

[0202] Optionally, for resources associated with a numerology, when allocating resources for each matching LCH according to the priority order of the LCH from high to low, in addition to the priority of the LCH, the attribute requirements of the LCH can be further considered (such as The maximum transmission interval), and the actual resourc...

Abstract

The present application discloses a resource allocation method, the method may include: for multiple resources associated with different parameter sets numerology, transmitting the data of the LCH on the resources matched by the LCH, wherein the LCH is configured with at least one attribute, The attribute is related to the numerology, and the resource matched by the LCH is the resource that least satisfies the attribute requirement of the LCH among the multiple resources. The above-mentioned solution can support multi-service transmission while comprehensively considering the attribute requirements (such as delay requirements) of LCHs used to carry various services, avoiding "oversatisfaction" for a certain (some) LCHs, and satisfying all LCHs as much as possible attribute requirements.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a resource allocation method, a related device and a system. Background technique [0002] Future communication systems, such as 5G and New Radio (NR) communication systems, will support at least three scenarios: Enhanced Mobile Broadband (Enhanced Mobile Broadband, eMBB), Massive Machine Type Communication (MassiveMachine Type Communication, mMTC) and High reliability, low latency communication (Ultra Reliable&LowLatency Communication, URLLC). Different services in these three scenarios have different transmission requirements. For example, URLLC services pay more attention to delay, while eMBB services pay more attention to bandwidth. In order to meet different transmission requirements, the system will configure different parameter sets (numerology) at the same time to support different business scenarios. [0003] The parameter set (numerology) ...
