Abstract
Provided by the present disclosure are data transmission method and device. In an embodiment of the present disclosure, data transmission conditions of each serving cell among at least two serving cells is detected by means of a terminal so that the terminal may, according to the data transmission conditions of each serving cell, execute random access on a serving cell experiencing wave beam failure so as to update a service beam of the serving cell. Thus, when the terminal experiences wave beam failure in a serving cell in a carrier aggregation (CA) scenario, reliable data transmission may be achieved, and the reliability of data transmission may be effectively ensured.
Claims10
A method for data transmission, comprising:
- detecting, by a terminal, data transmission situation of each of at least two serving cells, wherein the at least two serving cells comprise a primary cell and at least one secondary cell;
- and
- performing, by the terminal, random access on a serving cell where a beam failure occurs to update serving beam of the serving cell, according to the data transmission situation of each of the serving cells,
- wherein detecting the data transmission situation of each of the at least two serving cells comprises:
- maintaining, by the terminal, a timer and a counter configured in each of the serving cells, to count a number of times that the beam failure occurs in each of the serving cells within a running time of the timer configured in each of the serving cells, and
- wherein performing the random access on the serving cell comprises:
- performing, by the terminal, random access on the serving cell to update serving beam of the serving cell, in response to the number of times that the beam failure occurs in the serving cell being equal to or greater than a pre-configured threshold of number-of-times within the running time of the timer configured in the serving cell,
- wherein the running time of the timer is a duration after starting of the timer and before stopping, restarting, or expiring of the timer.
A device for data transmission, comprising a processor configured to:
- detect data transmission situation of each of at least two serving cells, wherein the at least two serving cells comprise a primary cell and at least one secondary cell;
- and
- perform random access on a serving cell where a beam failure occurs to update serving beam of the serving cell, according to the data transmission situation of each of the serving cells,
- wherein, to detect the data transmission situation of each of the at least two serving cells, the processor is configured to:
- maintain a timer and a counter configured in each of the serving cells to count a number of times that beam failure occurs in each of the serving cells within a running time of the timer configured in each of the serving cells, and
- wherein, to perform the random access on the serving cell, the processor is configured to:
- perform random access on the serving cell to update serving beam of the serving cell in response to the number of times that the beam failure occurs in the serving cell being equal to or greater than a pre-configured threshold of number-of-times within the running time of the timer configured in the serving cell,
- wherein the running time of the timer is a duration after starting of the timer and before stopping, restarting, or expiring of the timer.
