Abstract
A terminal device includes: a transmitter configured to transmit a scheduling request for an uplink (UL) resource; and control circuitry configured to stop an ongoing random access procedure when a media access control protocol data unit (MAC PDU) is transmitted using a configured Uplink (UL) grant other than a UL grant provided by a random access response in the random access procedure, wherein the configured UL grant indicates a resource configured prior to the ongoing random access procedure, wherein the MAC PDU includes a buffer status prior to the MAC PDU assembly.
Claims18
A terminal device comprising:
- a transmitter configured to transmit a scheduling request for an uplink (UL) resource;
- and
- control circuitry configured to stop an ongoing random access procedure when a media access control protocol data unit (MAC PDU) is transmitted using a configured Uplink (UL) grant other than a UL grant provided by a random access response in the random access procedure, wherein the configured UL grant indicates a resource configured prior to the ongoing random access procedure,
- wherein the MAC PDU includes a buffer status prior to the MAC PDU assembly.
A base station device comprising:
- a transmitter configured to transmit a random access response in a random access procedure or an uplink (UL) grant;
- a receiver configured to receive a media access control protocol data unit (MAC PDU) which is transmitted using a configured UL grant or to receive a MAC PDU which is transmitted using a UL grant provided by the random access response;
- and
- control circuitry configured to stop an ongoing random access procedure when the MAC PDU is transmitted using the configured UL grant other than the UL grant provided by the random access response in the random access procedure, wherein the configured UL grant indicates a resource configured prior to the ongoing random access procedure,
- wherein the MAC PDU includes a buffer status prior to the MAC PDU assembly.
A scheduling request method comprising:
- transmitting a scheduling request for an uplink (UL) resource;
- and
- stopping an ongoing random access procedure when a media access control protocol data unit (MAC PDU) is transmitted using a configured UL grant other than a UL grant by a random access response in the random access procedure, wherein the configured UL grant indicates a resource configured prior to the ongoing random access procedure,
- wherein the MAC PDU includes a buffer status prior to the MAC PDU assembly.
