Claim of US Patent No. 10,973,045

1. A method of semi-persistent transmission, comprising:sending, by a user equipment (UE) to a network device, a terminal capability report including indication information indicating whether the UE supports a plurality of sidelink-based parallel semi-persistent scheduling configurations,
wherein, in response to the terminal capability report indicating the UE supports a mechanism of the plurality of sidelink-based parallel semi-persistent scheduling configurations, the UE and the network device perform the following:
sending, by the UE to the network device, terminal assistance information, wherein the terminal assistance information includes service characterization information of at least one logical channel, and wherein the service characteristic information of each of the at least one logical channel includes a combination of a plurality of parameters including a logical channel identifier, a layer 2 target address, a data packet arrival period, a data packet arrival moment, a data packet size, and a data packet priority, and wherein the data packet priority is a ProSe Per-Packet Priority;
sending, by the network device to the UE, semi-persistent scheduling configuration information;
sending, by the network device to the UE, a semi-persistent scheduling activation message;
determining, by the UE, a semi-persistent transmission resource based on the semi-persistent scheduling configuration information and the semi-persistent scheduling activation message;
determining, by the UE, the at least one logical channel having a correspondence with the semi-persistent transmission resource; and
transmitting, by the UE on the semi-persistent transmission resource, data in the at least one logical channel having the correspondence with the semi-persistent transmission resource.
