Abstract
Official abstract text for this publication.
A terminal apparatus ( 20 ) according to an embodiment of the present disclosure includes a data processing unit ( 201 ) and a wireless signal processing unit ( 202 ). The data processing unit ( 201 ) generates a first frame including a requirement related to a latency during data communication and inquiring a base station ( 10 ) whether communication that satisfies the requirement is possible. The wireless signal processing unit ( 202 ) transmits the first frame.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A base station comprising: a data processing unit, implemented with one or more processors, configured to determine whether or not communication that satisfies a requirement related to a latency during data communication is possible when receiving, from a terminal apparatus, a first frame including the requirement; and a wireless signal processing unit, implemented with the one or more processors, configured to transmit a permission notification to the terminal apparatus when it is determined that the communication that satisfies the requirement is possible, wherein, when receiving a second frame including information related to a buffer status of data transmitted from the terminal apparatus in accordance with the requirement, the data processing unit is configured to determine from the buffer status and a traffic status whether or not there is a probability that the requirement is not satisfied in subsequent communication, and the base station further comprises a control unit, implemented with the one or more processors, configured to control a transmission opportunity (TXOP) such that communication with the terminal apparatus is prioritized when it is determined that there is the probability that the requirement is not satisfied in the subsequent communication. 2 . The base station according to claim 1 , wherein the control unit is configured to extend a transmission opportunity period to be allocated to the terminal apparatus as an amount of data indicated in the buffer status increases. 3 . The base station according to claim 1 , wherein the control unit is configured to control the transmission opportunity of the terminal apparatus using at least one of a polling frame, a trigger frame, and a beacon signal each including a parameter that prioritizes communication with the terminal apparatus.
