Abstract: Embodiments of this application disclose a message transmission method and apparatus, a terminal, and a base station. In the method, a symbol or symbol group may be used as a granularity to select a plurality of symbols or symbol groups from one or more slots and then allocate the plurality of symbols or symbol groups to a same terminal for transmitting data. The plurality of symbols or symbol groups may be used for uplink data scheduling or may be used for downlink data scheduling. Therefore, a slot resource is allocated at a small granularity, so that a time domain resource is more flexibly allocated, and the slot resource is more fully utilized. This helps improve message transmission efficiency, thereby expanding a coverage area.

Abstract: The present invention relates to the wireless communications field, and provides a scheduling method, a device, and a system, to resolve a problem that a scheduling resource is wasted when SPS transmission with a relatively short scheduling interval is applied to a V2X service. The scheduling method provided in the present invention includes: receiving, by a first device, semi-persistent scheduling SPS configuration information from a second device; receiving, by the first device, SPS activation information from the second device, where the SPS activation information is used to indicate an activated SPS resource; and sending, by the first device, the SPS instruction information to the second device, where the SPS instruction information is used to instruct to use or not to use a scheduling resource of the activated SPS resource. Embodiments of the present invention are applied to V2X communication.

Abstract: The present disclosure relates to a method for determining a first-link transmit power. In one example method, a user equipment (UE) obtains transmit power indication information of a first link. The UE determines a first transmit power of control information and a second transmit power of data based on the transmit power indication information. The UE sends the control information at the first transmit power, and the data at the second transmit power. The control information and the data are sent on the first link in a same subframe.
