Abstract
A method and device for transmitting a scheduling request, the method includes: transmitting a scheduling request to a network device via a random access procedure when a maximum counter value of a scheduling request configuration is reached; information on the scheduling request configuration is transmitted to the network device during the random access procedure. Therefore, the network device can know which SR configuration that the terminal device would like to reconfigure upon reception of the RACH message; and only one or more resources corresponding to the SR configuration may be released, such that service interruption for other LCGs/LCHs may not happen.
Claims20
A method in a terminal device, comprising:
- transmitting a scheduling request to a network device via a random access procedure when a maximum counter value of a scheduling request configuration is reached, the maximum counter value being a maximum number of times the terminal device has transmitted a scheduling request without receiving resource assignments from the network device and information on the scheduling request configuration conveyed to the network device during the random access procedure, the information on the scheduling request configuration transmitted to the network device in a message of the random access procedure, the message comprising an identity of the terminal device and the information on one or more scheduling request configurations when the maximum counter value of the one or more scheduling request configurations is reached;
- and
- releasing resources of at least one scheduling request configuration when the maximum counter value of the at least one scheduling request configuration is reached, the resources of the at least one scheduling request configuration being released based on at least one of a priority level and quality of the at least one scheduling request configuration.
A method in a network device, comprising:
- receiving a scheduling request from a terminal device via a random access procedure, the scheduling request being triggered in the terminal device when a maximum counter value of a scheduling request configuration is reached and information on the scheduling request configuration conveyed to the network device during the random access procedure, the maximum counter value being a maximum number of times the terminal device has transmitted a scheduling request without receiving resource assignments from the network device, the information on the scheduling request configuration received by the network device in a message of the random access procedure, the message comprising an identity of the terminal device and the information on one or more scheduling request configurations when the maximum counter value of the one or more scheduling request configurations is reached;
- and
- triggering a release of resources of at least one scheduling request configuration in the terminal device when the maximum counter value of the at least one scheduling request configuration is reached, the resources of the at least one scheduling request configuration being released based on at least one of a priority level and quality of the at least one scheduling request configuration.
A terminal device, comprising:
- a processor;
- and a memory, the memory containing instructions executable by the processor whereby the terminal device is operative to:
- transmit a scheduling request to a network device via a random access procedure when a maximum counter value of a scheduling request configuration is reached, the maximum counter value being a maximum number of times the terminal device has transmitted a scheduling request without receiving resource assignments from the network device and information on the scheduling request configuration conveyed to the network device during the random access procedure, the information on the scheduling request configuration transmitted to the network device in a message of the random access procedure, the message comprising an identity of the terminal device and the information on one or more scheduling request configurations when the maximum counter value of the one or more scheduling request configurations is reached;
- and
- release resources of at least one scheduling request configuration when the maximum counter value of the at least one scheduling request configuration is reached, the resources of the at least one scheduling request configuration being released based on at least one of a priority level and quality of the at least one scheduling request configuration.
