Claim of US Patent No. 10,798,708

1. A method for a data transmission in a wireless network, the method comprising:first determining, by a terminal device, a first configuration information that is used for second determining at least one first sidelink logical channel that is used to transmit direct communication data;
third determining, by the terminal device, that a type-1 data and a type-2 data need to be transmitted at a same time; and
allocating, by the terminal device in response to the third determining, a first transmit power for a first data based on the first configuration information,
wherein the type-1 data and the type-2 data are a service data of two distinct types that are to be transmitted by using distinct transmission resources, and the first data is the type-1 data to be transmitted by using the first sidelink logical channel,
wherein the first configuration information comprises a first identifier taken from the group consisting of:
a priority identifier, and
a logical channel identifier;
wherein the second determining comprises determining, by the terminal device as the at least one first sidelink logical channel:
a sidelink logical channel having the first identifier;
a sidelink logical channel not having the first identifier; or
when at least one of sidelink logical channels associated with data encapsulated in a protocol data unit of the terminal device has the first identifier, all the sidelink logical channels associated with the data encapsulated in the protocol data unit, as the first sidelink logical channels;
wherein the allocating comprises allocating the first transmit power for the first data based on a first limited power,
wherein the first transmit power is:
higher than the first limited power, and
lower than or equal to a maximum transmit power currently allowed by the terminal device; and
wherein the first limited power has a mapping relationship with the first identifier and indicates a maximum available transmit power for a data transmitted on a sidelink logical channel of the at least one first sidelink logical channel indicated by the first identifier.
