Abstract
A user equipment (UE) receives a grant on a semi-persistent scheduling (SPS) resource from an eNodeB (eNB). The UE determines that the SPS resource cannot accommodate an amount of data available for transmission for a specific logical channel. The UE transmits the SPS scheduling information for the specific logical channel to the eNB. The SPS scheduling information for the specific logical channel may be a scheduling request for the specific logical channel, and may be transmitted on an additional L1 control resource.
Claims20
A method performed by a wireless device in a wireless communication system, the method comprising:
- receiving a first semi-persistent scheduling (SPS) configuration including a first SPS resource from a base station,
- wherein a logical channel is related to the first SPS resource;
- performing transmission of data available for the logical channel based on the first SPS resource;
- while performing the transmission based on the first SPS resource, and based on additional data for a logical channel being available, wherein the additional data does not include the data being transmitted on the first SPS resource, informing the base station about the additional data available for the logical channel;
- and
- receiving a second SPS resource from the base station,
- wherein the second SPS resource is for transmitting the additional data,
- wherein the second SPS resource is included in a dedicated radio resource configuration, and
- wherein the wireless device suspends the second SPS resource upon a specific event while keeping configuration of the second SPS resource.
A wireless device in a wireless communication system comprising:
- a transceiver;
- a memory;
- and
- at least one processor operatively coupled to the transceiver and the memory, and configured to:
- control the transceiver to receive a first semi-persistent scheduling (SPS) configuration including a first SPS resource from a base station,
- wherein a logical channel is related to the first SPS resource;
- control the transceiver to perform transmission of data available for the logical channel based on the first SPS resource;
- while performing the transmission based on the first SPS resource, and based on additional data for a logical channel being available, wherein the additional data does not include the data being transmitted on the first SPS resource, control the transceiver to inform the base station about the additional data available for the logical channel;
- and
- control the transceiver to receive a second SPS resource from the base station,
- wherein the second SPS resource is for transmitting the additional data,
- wherein the second SPS resource is included in a dedicated radio resource configuration, and
- wherein the wireless device suspends the second SPS resource upon a specific event while keeping configuration of the second SPS resource.
A non-transitory computer-readable medium having stored thereon a plurality of instructions, which, based on being executed by a processor of a wireless device, cause the wireless device to:
- receive a first semi-persistent scheduling (SPS) configuration including a first SPS resource from a base station,
- wherein a logical channel is related to the first SPS resource;
- perform transmission of data available for the logical channel based on the first SPS resource;
- while performing the transmission based on the first SPS resource, and based on additional data for a logical channel being available, wherein the additional data does not include the data being transmitted on the first SPS resource, inform the base station about the additional data available for the logical channel;
- and
- receive a second SPS resource from the base station,
- wherein the second SPS resource is for transmitting the additional data,
- wherein the second SPS resource is included in a dedicated radio resource configuration, and
- wherein the wireless device suspends the second SPS resource upon a specific event while keeping configuration of the second SPS resource.
