Abstract
Example embodiments of the present disclosure relate to a terminal device, a network device, methods, apparatuses and a computer readable storage medium for reducing cell activation delay. A terminal device determines, during an activation procedure of a secondary cell, at least one measurement result of the secondary cell at the terminal device, and performs a layer 1 measurement on the secondary cell based, at least partially, on the at least one measurement result. As such, there is no need to perform the layer 1 measurement on full beams and the time length of the activation procedure may be shorter. Thus, the activation delay can be reduced, the power consumption can be reduced, and the communication efficiency may be improved.
Claims21
1-39. (canceled)
A terminal device comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the terminal device at least to:
- determine, during an activation procedure of a secondary cell, at least one measurement result of the secondary cell at the terminal device;
- and
- determine a measurement delay for a layer 1 measurement on the secondary cell based, at least partially, on the at least one measurement result,
- wherein the at least one measurement result comprises at least one layer 3 measurement result.
A method comprising:
- determining, at a terminal device during an activation procedure of a secondary cell, at least one measurement result of the secondary cell at the terminal device;
- and
- determine a measurement delay for a layer 1 measurement on the secondary cell based, at least partially, on the at least one measurement result,
- wherein the at least one measurement result comprises at least one layer 3 measurement result.
A network device comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the network device at least to:
- transmit, to a terminal device in a primary cell, an activation command indicating a permission that the terminal device is allowed to perform a fast layer 1 measurement during an activation procedure of a secondary cell;
- and
- receive, from the terminal device, a layer 1 measurement report of a layer 1 measurement indicating, based on a measurement delay, whether the layer 1 measurement performed at the terminal device is the fast layer 1 measurement,
- wherein the layer 1 measurement report is based, at least partially, on at least one layer 3 measurement result.
