1. A resource allocation method performed by a terminal, comprising:
determining a sidelink grant;
allocating resources to sidelink logical channels according to the sidelink grant and a mapping relationship between the sidelink logical channels and logical channel prioritization restrictions parameters,
wherein the logical channel prioritization restrictions parameters comprise at least one of following parameters:
a list of radio access technologies allowed to be used at a sidelink by a logical channel;
a list of resource types allowed to be used at a sidelink by a logical channel;
a list of subcarrier spacings allowed to be used at a sidelink by a logical channel;
a maximum length of a transmission time interval allowed to be used at a sidelink by a logical channel,
wherein the method further comprises:
acquiring the mapping relationship, configured by a resource allocation management node, between logical channels and logical channel prioritization restrictions parameters by the terminal, wherein acquiring the mapping relationship, configured by the resource allocation management node, between logical channels and logical channel prioritization restrictions parameters comprises:
reporting logical channels of each sidelink and radio access technologies and/or resource types corresponding to the logical channels of each sidelink to the resource allocation management node, or reporting logical channels of each sidelink and quality-of-service parameters corresponding to the logical channels of each sidelink to the resource allocation management node;
acquiring the mapping relationship, configured by the resource allocation management node, between logical channels and logical channel prioritization restrictions parameters;
or,
acquiring a mapping relationship, configured by the resource allocation management node, between quality-of-service parameters corresponding to sidelink logical channels and logical channel prioritization restrictions parameters, and after acquiring a mapping relationship, configured by the resource allocation management node, between quality-of-service parameters corresponding to sidelink logical channels and logical channel prioritization restrictions parameters, the method further comprises:
determining the mapping relationship between logical channels and logical channel prioritization restrictions parameters, according to the quality-of-service parameters corresponding to sidelink logical channels and according to the mapping relationship between the quality-of-service parameters corresponding to the sidelink logical channels and the logical channel prioritization restrictions parameters.
