Wireless communications method and device for transmitting scheduling request
View Patent ↗The present disclosure provides a method performed by user equipment. The method comprises: initiating a first timer based on a state related to a scheduling request; and when the first timer expires, then transmitting information related to the scheduling request. Furthermore, the present disclosure further provides corresponding user equipment.
1. A user equipment (UE) for transmitting a Scheduling Request (SR), comprising:
reception circuitry configured to receive a radio resource control (RRC) message from a network, the RRC message including an information element, the information element indicating to the UE to activate a function of carrying the SR using an acknowledgement or negative acknowledgement (ACK/NACK) resource;
determining circuitry configured to determine whether a medium access control (MAC) entity has a valid physical uplink shared channel (PUSCH) resource for carrying an ACK/NACK and whether the function is activated;
instruction circuitry configured to, in response to the determining circuitry determining that the MAC entity has a valid PUSCH resource for carrying the ACK/NACK and the function is activated, instruct a physical layer to signal the SR on the valid PUSCH resource for carrying the ACK/NACK; and
transmission circuitry configured to transmit the SR on a PUSCH on the valid PUSCH resource for carrying the ACK/NACK.
2. A method for transmitting a Scheduling Request (SR) at a user equipment (UE), the method comprising:
receiving a radio resource control (RRC) message from a network, the RRC message including an information element, the information element indicating to the UE to activate a function of carrying the SR using an acknowledgement or negative acknowledgement (ACK/NACK) resource;
determining whether a medium access control (MAC) entity has a valid physical uplink shared channel (PUSCH) resource for carrying an ACK/NACK and whether the function is activated;
in response to determining that the MAC entity has a valid PUSCH resource for carrying the ACK/NACK and the function is activated, instructing a physical layer to signal the SR on the valid PUSCH resource for carrying the ACK/NACK; and
transmitting the SR on a PUSCH on the valid PUSCH resource for carrying the ACK/NACK.
