Abstract:
Embodiments of the present invention provide a service data transmission method and an apparatus, and relate to the communications field, so as to resolve a problem that spectrum utilization in the prior art is relatively low. The method includes: obtaining, by a base station, use permission of at least one first spectrum; broadcasting, by the base station, a service migration message to a terminal by using a second spectrum, where the service migration message is used to instruct the terminal to receive service data on the at least one first spectrum; and sending, by the base station, the service data to the terminal by using the at least one first spectrum. The embodiments of the present invention are applicable to a case in which a base station sends service data to a terminal.
Abstract:
Embodiments of the present invention provide a spectrum detection method and apparatus, and a base station. According to the method, in the embodiments, a first base station sends spectrum detection information to an auxiliary device, where the spectrum detection information is used to instruct the auxiliary device to detect whether a first spectrum is occupied; then, the first base station receives first spectrum status information sent by the auxiliary device, so that the first base station determines whether the first spectrum in an area in which the auxiliary device is located is occupied. Therefore, it is implemented that the first base station may determine whether user equipment is interfered by another communications system device in a process in which the user equipment uses the first spectrum, so as to implement sharing of a spectrum by the user equipment with the another communications system device.
Abstract:
Embodiments of the present application disclose a method, an apparatus, and a system for transmission control of multimedia broadcast multicast data. The method includes: according to a reference time, determining a scheduling period of suspending or resuming sending MBMS service data; and suspending or resuming sending the MBMS service data in the determined scheduling period. According to the embodiments of the present application, transmission control of the MBMS service data by a base station can be realized, which facilitates each base station in the same MBSFA range synchronously suspending or resuming sending the MBMS service data of the same service, thereby facilitating reducing interferences in the service.
Abstract:
Embodiments disclose a data processing method, and a communications device and system. The method includes: transmitting, by a communications device, a data packet to a receiving node by using an unlicensed spectrum resource and by using a hybrid automatic repeat request process. The method also includes determining, by the communications device, that the unlicensed spectrum resource is unavailable and an unsuccessfully-sent data packet exists in the hybrid automatic repeat request process. The method also includes triggering, by the communications device, ARQ retransmission for the unsuccessfully-sent data packet.
Abstract:
Embodiments of this application relate to the communications field, and provide an uplink control information transmission method and an apparatus, to effectively ensure that when user equipment has both a PUCCH resource and a PUSCH resource, UCI can be transmitted to a base station. The method includes: pre-configuring, by user equipment, first uplink control information UCI and second UCI, where the first UCI is carried on a PUSCH resource of a first cell for transmission, the second UCI is carried on a PUCCH resource for transmission, and the first cell is a cell on which CCA or LBT detection needs to be performed; and sending, by the user equipment, the first UCI or the second UCI to a base station. The method and the apparatus are used for UCI transmission.
Abstract:
The present disclosure provides a processing method and device for obtaining synchronization, where the method includes: selecting, by a UE, a preamble on a first Scell, and reporting information of the preamble to a base station by using a current PCell or a second SCell of the UE; receiving scheduling information of a random access response message or scheduling information of a conflict indication message delivered by the base station from a physical downlink control channel of the PCell, the second SCell or the first SCell by using a C-RNTI of the UE; and receiving the random access response message or the conflict indication message from a physical downlink shared channel according to the scheduling information of the random access response message or the scheduling information of the conflict indication message.
Abstract:
A method for controlling an uplink transmit power in an inter-bas station carrier aggregation, a base station and a device are disclosed. In an embodiment the method includes providing for a first base station, by a second base station, a status of an uplink resource that is scheduled by the second base station for a user equipment (UE), wherein a maximum uplink transmit power that is allocated by the UE to the first base station is based on the status of the uplink resource and scheduling for the UE, by the second base station, the uplink resource according to the status of the uplink resource.
