Abstract

Provided are a signal sending and receiving method and device. The signal sending device includes: a first transmission module ( 301 ), configured to send at least one of a signal and a channel to a second-type node on a first frequency domain resource set, or send at least one of the signal and the channel to the second-type node on the first frequency domain resource set and a second frequency domain resource set; where each of the first frequency domain resource set and the second frequency domain resource set is a resource element (RE) set on a physical carrier, and a position of the center RE of the first frequency domain resource set is associated with a channel number of the physical carrier.

First claim

What is claimed is:

1. A wireless communication method, comprising:
transmitting, from a base station to a terminal, a synchronization signal and a broadcast channel using a first set of resource elements, wherein the first set of resource elements is in a physical carrier that is identified by a range of channel numbers, and wherein the broadcast channel carries bandwidth information about a second set of resource elements; and
transmitting, based on the bandwidth information about the second set of resource elements, information to the terminal using the second set of resource elements,
wherein a frequency domain index of a center resource element of the first set of resource elements is associated with a channel number in the range; and
wherein, within a subrange of the channel numbers, an absolute value of a difference between two frequency domain indices of center resource elements associated with adjacent channel numbers is 1 or 2.

2. The method of claim 1 , wherein the information to the terminal is used for transmitting a system message.

3. A wireless communication method, comprising:
receiving, by a terminal from a base station, a synchronization signal and a broadcast channel using a first set of resource elements, wherein the first set of resource elements is in a physical carrier that is identified by a range of channel numbers, and wherein the broadcast channel carries bandwidth information about a second set of resource elements; and
receiving, based on the bandwidth information about the second set of resource elements, information from the base station using the second set of resource elements,
wherein a frequency domain index of a center resource element of the first set of resource elements is associated with a channel number in the range; and
wherein, within a subrange of the channel numbers, an absolute value of a difference between two frequency domain indices of center resource elements associated with adjacent channel numbers is 1 or 2.

4. The method of claim 3 , wherein the information from the base station is used for receiving a system message.

5. The method of claim 3 , comprising:
determining, by the terminal, information identifying a frequency-domain position of a center resource element of a set of resource elements in the broadcast channel.

6. A wireless communication device, comprising:
a processor, and
a memory including processor executable code, wherein the processor executable code upon execution by the processor configures the processor to:
transmit a synchronization signal and a broadcast channel using a first set of resource elements to a terminal, wherein the first set of resource elements is in a physical carrier that is identified by a range of channel numbers, and wherein the broadcast channel carries bandwidth information about a second set of resource elements; and
transmit, based on the bandwidth information about the second set of resource elements, information to the terminal using the second set of resource elements, wherein a frequency domain index of a center resource element of the first set of resource elements is associated with a channel number in the range; and
wherein, within a subrange of the channel numbers, an absolute value of a difference between two frequency domain indices of center resource elements associated with adjacent channel numbers is 1 or 2.

7. The device of claim 6 , wherein the information to the terminal is used for transmitting a system message.

8. A wireless communication device, comprising:
a processor, and
a memory including processor executable code, wherein the processor executable code upon execution by the processor configures the processor to:
receive a synchronization signal and a broadcast channel using a first set of resource elements from a base station, wherein the first set of resource elements is in a physical carrier that is identified by a range of channel numbers, and wherein the broadcast channel carries bandwidth information about a second set of resource elements; and
receive, based on the bandwidth information about the second set of resource elements, information from the base station using the second set of resource elements,
wherein a frequency domain index of a center resource element of the first set of resource elements is associated with a channel number in the range; and
wherein, within a subrange of the channel numbers, an absolute value of a difference between two frequency domain indices of center resource elements associated with adjacent channel numbers is 1 or 2.

9. The device of claim 8 , wherein the information from the base station is used for receiving a system message.

10. The device of claim 8 , wherein the processor is configured to determine information identifying a frequency domain position of a center resource element of a set of resource elements in the broadcast channel.

11. A non-transitory storage medium having code stored thereon, the code upon execution by a processor, causing the processor to implement a method that comprises:
transmitting, from a base station to a terminal, a synchronization signal and a broadcast channel using a first set of resource elements, wherein the first set of resource elements is in a physical carrier that is identified by a range of channel numbers, and wherein the broadcast channel carries bandwidth information about a second set of resource elements; and
transmitting, based on the bandwidth information about the second set of resource elements, information to the terminal using the second set of resource elements,
wherein a frequency domain index of a center resource element of the first set of resource elements is associated with a channel number in the range; and
wherein, within a subrange of the channel numbers, an absolute value of a difference between two frequency domain indices of center resource elements associated with adjacent channel numbers is 1 or 2.

12. The non-transitory storage medium of claim 11 , wherein the information to the terminal is used for transmitting a system message.

13. A non-transitory storage medium having code stored thereon, the code upon execution by a processor, causing the processor to implement a method that comprises:
receiving, by a terminal from a base station, a synchronization signal and a broadcast channel using a first set of resource elements, wherein the first set of resource elements is in a physical carrier that is identified by a range of channel numbers, and wherein the broadcast channel carries bandwidth information about a second set of resource elements; and
receiving, based on the bandwidth information about the second set of resource elements, information from the base station using the second set of resource elements,
wherein a frequency domain index of a center resource element of the first set of resource elements is associated with a channel number in the range; and
