Method for transmitting signal, terminal device and network device
View Patent ↗Disclosed are a method for transmitting a signal, a terminal device and a network device. The method comprises: a terminal device determining a time domain position, in a first transmission cycle, of a synchronization signal block burst of a cell where the terminal device is located; and the terminal device receiving, according to the time domain position of the synchronization signal block burst in the first transmission cycle, a synchronization signal block sent by a network device. The method, the terminal device and the network device in the embodiments of the prevent application can reduce the computation complexity of the terminal device, reduce the detection time and save on the power consumption.
1. A signal transmission method, comprising:
determining, by a terminal device, a time-domain position of a synchronization signal (SS) block burst of a serving cell of the terminal device in a first transmission cycle; and
receiving, by the terminal device, one or more SS blocks from a network device based on the time-domain position of the SS block burst in the first transmission cycle,
the method further comprising:
receiving, by the terminal device, indication information from the network device, wherein the indication information indicates a number of SS blocks in the burst,
wherein determining, by the terminal device, the time-domain position of the SS block burst of the serving cell of the terminal device in the first transmission cycle comprises:
determining, by the terminal device, the time-domain position of the SS block burst in the first transmission cycle based on the number of the SS blocks in the burst.
2. The method of claim 1 , wherein the indication information is carried in at least one of a broadcast message, a system message, RRC signaling, media access control (MAC) control element (CE) signaling, or downlink control information (DCI).
3. The method of claim 1 , wherein receiving, by the terminal device, the indication information from the network device comprises:
receiving, by the terminal device, the indication information from the network device on a primary carrier.
4. The method of claim 3 , wherein the primary carrier is a carrier in a New Radio (NR) system or a Long Term Evolution (LTE) system.
5. The method of claim 1 , wherein the SS block comprises a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).
6. A terminal device, comprising:
a processor, configured to determine a time-domain position of the SS block burst of a serving cell of the terminal device in a first transmission cycle; and
an input interface, configured to receive one or more SS blocks from a network device based on the time-domain position of the SS block burst in the first transmission cycle,
wherein the input interface is further configured to receive indication information from the network device, wherein the indication information indicates a number of SS blocks in the burst, and
wherein the processor is configured to:
determine the time-domain position of the SS block burst in the first transmission cycle based on the number of the SS blocks in the burst.
7. The terminal device of claim 6 , wherein the indication information is carried in at least one of a broadcast message, a system message, RRC signaling, media access control (MAC) control element (CE) signaling, or downlink control information (DCI).
8. The terminal device of claim 6 , wherein the input interface is configured to:
receive the indication information from the network device on a primary carrier.
9. The terminal device of claim 8 , wherein the primary carrier is a carrier in a New Radio (NR) system or a Long Term Evolution (LTE) system.
10. The terminal device of claim 6 , wherein the SS block comprises a primary synchronization signal (PSS) and a secondary synchronization signal (SSS).
