Abstract
Embodiments of the disclosure generally relate to configuring a measurement gap. A network device obtains information about a first frequency region and a second frequency region. The first frequency region is being used for transmitting a first synchronization signal from a serving cell managed by the network device, and the second frequency region is used for transmitting a second synchronization signal from a neighbor cell of the serving cell. Then, the network device determines a configuration for a measurement gap based on the first and second frequency regions, and transmits the configuration for the measurement gap to the terminal device.
Claims14
A method at a network device, comprising:
- obtaining information about a first frequency region and a second frequency region, the first frequency region being used for transmitting a first synchronization signal from a serving cell managed by the network device, and the second frequency region being used for transmitting a second synchronization signal from a neighbor cell of the serving cell;
- determining a configuration for a measurement gap based on the first frequency region and the second frequency region, the configuration indicating presence or absence of the measurement gap for a terminal device in the serving cell to measure the second synchronization signal;
- and
- transmitting the configuration for the measurement gap to the terminal device independent of the presence or absence of the measurement gap.
A method at a terminal device, comprising:
- receiving a configuration for a measurement gap from a network device managing a serving cell, the configuration for the measurement gap being determined based on a first frequency region and a second frequency region and indicating presence or absence of the measurement gap for the terminal device to measure the second synchronization signal, the first frequency region being used for transmitting a first synchronization signal from the serving cell, and the second frequency region being used for transmitting a second synchronization signal from a neighbor cell of the serving cell;
- and
- measuring the second synchronization signal based on the configuration for the measurement gap independent of the presence or absence of the measurement gap.
A method at a network device, comprising:
- receiving, from a serving network device managing a serving cell, a request for aligning a second frequency region to a first frequency region, the first frequency region being used for transmitting a first synchronization signal from the serving cell, the second frequency region being used for transmitting a second synchronization signal from a neighbor cell of the serving cell, and the neighbor cell being managed by the network device;
- generating a response indicating whether the second synchronization signal is aligned to the first synchronization signal such that the serving network device can determine a configuration for a measurement gap based on the first frequency region and the second frequency region, the configuration indicating presence or absence of the measurement gap for a terminal device in the serving cell to measure the second synchronization signal;
- and
- transmitting the response to the serving network device.
A terminal device, comprising:
- a processor and a memory, the memory containing program including instructions executable by the processor, the processor being configured to cause the terminal device to:
- receive a configuration for a measurement gap from a network device managing a serving cell, the configuration for the measurement gap being determined based on a first frequency region and a second frequency region and indicating presence or absence of the measurement gap for the terminal device to measure the second synchronization signal, the first frequency region being used for transmitting a first synchronization signal from the serving cell, and the second frequency region being used for transmitting a second synchronization signal from a neighbor cell of the serving cell;
- and
- measure the second synchronization signal based on the configuration for the measurement gap independent of the presence or absence of the measurement gap.
