Abstract
A base station apparatus appropriately controls scheduling of an uplink. A terminal apparatus includes measuring means for measuring an elapsed time from when a packet is received from a higher layer to when the uplink data is transmitted to the base station apparatus by using the radio resource for the uplink, and transmitting means for transmits the measured elapsed time to the base station apparatus as a delay time.
Claims11
A terminal apparatus configured to transmit uplink data to a base station apparatus by using a radio resource for an uplink allocated by the base station apparatus, comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- measure an eapsed time from when a packet is received from a higher layer to when the uplink data is transmitted to the base station apparatus by using the radio resource for the uplink;
- and
- transmit the measured elapsed time to the base station apparatus as a delay time.
A base station apparatus configured to perform scheduling of an uplink according to a buffer state report indicating a buffer size of uplink data transmitted from a terminal apparatus, comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to process the instructions to:
- receive an elapsed time from the terminal apparatus as a delay time, the elapsed time being a time from when the terminal apparatus receives a packet from a higher layer to when the uplink data is transmitted to the base station apparatus by using a radio resource for the uplink allocated by the base station apparatus;
- and
- perform scheduling of the uplink based on the delay time.
A communication system comprising a terminal apparatus configured to transmit uplink data to a base station apparatus by using a radio resource for an uplink allocated by the base station apparatus, and a base station apparatus configured to perform scheduling of the uplink according to a buffer state report indicating a buffer size of the uplink data transmitted from the terminal apparatus, wherein
- the terminal apparatus comprises:
- at least one terminal memory storing terminal instructions;
- and
- at least one terminal processor configured to process the terminal instructions to:
- measure an elapsed time from when a packet is received from a higher layer to when the uplink data is transmitted to the base station apparatus by using the radio resource for the uplink;
- and
- transmit the measured elapsed time to the base station apparatus as a delay time, and
- the base station apparatus comprises:
- at least one base station memory storing terminal instructions;
- and
- at least one base station processor configured to process the base station instructions to:
- receive the delay time from the terminal apparatus;
- and
- perform scheduling of the uplink based on the delay time.
A communication method for a terminal apparatus configured to transmit uplink data to a base station apparatus by using a radio resource for an uplink allocated by the base station apparatus, the communication method comprising:
- measuring an elapsed time from when a packet is received from a higher layer to when the uplink data is transmitted to the base station apparatus by using the radio resource for the uplink;
- and
- transmitting the measured elapsed time to the base station apparatus as a delay time.
A non-transitory computer readable medium storing a program for a computer provided in a terminal apparatus configured to transmit uplink data to a base station apparatus by using a radio resource for an uplink allocated by the base station apparatus, the program being configured to cause the computer to perform:
- a process for measuring an elapsed time from when a packet is received from a higher layer to when the uplink data is transmitted to the base station apparatus by using the radio resource for the uplink;
- and
- a process for transmitting the measured elapsed time to the base station apparatus as a delay time.
A method of a User Equipment (UE), the method comprising:
- triggering a procedure which is used to provide a Radio Access Network (RAN) node with delay status of a Logical Channel Group (LCG);
- and
- transmitting, to the RAN node, a first Medium Access Control (MAC) Control Element (CE) which corresponds to a first Logical Channel Identifier (ID) for a Uplink Shared Channel (UL-SCH),
- wherein the first MAC CE includes delay information of the LCG.
