Abstract:
A method for indicating a synchronization signal period and an apparatus are provided. In one example, a base station indicates a synchronization signal period to a terminal, and after determining the synchronization signal period, the terminal receives a synchronization signal of a corresponding beam according to the synchronization signal period.
Abstract:
A terminal device and a power allocation method are disclosed, relates to the field of communications network technologies. In embodiments of the present disclosure, at least one uplink channel of a first target subframe numbered i is determined; according to uplink channel information of a second target subframe numbered x, a reserved power that is reserved for a base station or a cell group in which the second target subframe numbered x is located is determined, where the reserved power is determined when uplink channel information of the second target subframe numbered x includes a PRACH or includes only an SRS channel or includes no channel. According to the reserved power, a transmit power of each uplink channel in the at least one uplink channel of the first target subframe numbered i is determined. Solutions provided in the embodiments of the present disclosure are applicable to power allocation.
Abstract:
Embodiments of the present invention provide a method, a base station, and a user equipment for activating or deactivating a carrier. The method includes the following: A base station determines to activate or deactivate at least one secondary carrier used to communication with a user equipment and transmits a High Speed Shared Control Channel HS-SCCH order to the user equipment, where the HS-SCCH order carries indication information used to indicate activation or deactivation of the at least one secondary carrier. In the embodiments of the present invention, a user equipment is capable of correctly activating or deactivating a carrier.
Abstract:
An information configuration method, a data receiving method, and a device are provided. A first network device configures a first resource set group of a physical downlink control channel set for user equipment, and configures for the user equipment, a second resource set group of a physical downlink control channel for retransmission, where the physical downlink control channel for retransmission is a physical downlink control channel for retransmission corresponding to downlink data indicated by a physical downlink control channel in at least one subset of the physical downlink control channel set. The first network device sends information about the first resource set group and information about the second resource set group to the user equipment.
Abstract:
A method, a user equipment (UE) and a communication system are provided. In the disclosure, a UE configured with multiple carriers determines whether a first, a second, and a third conditions are met, and then determines whether resources allocated for the UE on the carrier are sufficient or not accordingly. The first condition defines that the UE is transmitting as much scheduled data as allowed by a current service grant on the carrier. The second condition indicates that the UE has enough transmission power available to transmit data at higher data rate on the carrier. The third condition indicates total buffer data requires more than a preconfigured time period to be transmitted through the carrier together with at least one of other carriers among the multiple carriers.
Abstract:
Embodiments of the present invention disclose a method and an apparatus for indicating a transmission time interval. The implementation solutions of the method includes: receiving an access preamble from a user equipment UE, where the access preamble carries a signature; determining whether a cell where the UE is located is configured with an extended acquisition indicator EAI, and sending, on an acquisition indicator channel AICH of an access timeslot corresponding to an access timeslot where the access preamble is received, an acquisition indicator AI corresponding to the signature of the access preamble. Therefore, the problem that the judging condition of EAI configured is always YES is solved; the UE access delay may be reduced; the number of preambles sent by the UE may be reduced; and interference on the uplink may be reduced.
