Abstract
A user equipment (UE) receives a SPS resource configuration from an eNodeB (eNB), and transmits information related to a semi-persistent scheduling (SPS) activation for a specific logical channel to the eNB. The information may include timing information for the specific logical channel which indicates when a SPS resource for the specific logical channel should be activated. The specific logical channel may correspond to a vehicle-to-everything (V2X) communication.
Claims18
A method performed by a wireless device in a wireless communication system, the method comprising:
- entering a connected mode;
- transmitting, to a network, a request message for requesting periodic scheduling of uplink resources while the wireless device is in the connected mode, wherein the request message comprises timing information for at least one periodic uplink resource;
- receiving, from the network, a radio resource control (RRC) connection release message comprising an uplink resource configuration, wherein the uplink resource configuration comprises information for the at least one periodic uplink resource and information for a validity duration during which a transmission using the at least one periodic uplink resource is valid;
- storing the uplink resource configuration to be maintained after receiving the RRC connection release message;
- and
- performing the transmission using the at least one periodic uplink resource to the network during the validity duration,
- wherein the at least one periodic uplink resource is valid at a specific cell, and
- wherein the transmission comprises a physical uplink shared channel (PUSCH) transmission.
A wireless device in a wireless communication system, the wireless device comprising:
- a transceiver;
- a memory;
- and
- at least one processor operatively coupled to the transceiver and the memory,
- wherein the at least one processor is configured to:
- enter a connected mode;
- control the transceiver to transmit, to a network, a request message for requesting periodic scheduling of uplink resources while the wireless device is in the connected mode, wherein the request message comprises timing information for at least one periodic uplink resource;
- control the transceiver to receive, from the network, a radio resource control (RRC) connection release message comprising an uplink resource configuration, wherein the uplink resource configuration comprises information for the at least one periodic uplink resource and information for a validity duration during which a transmission using the at least one periodic uplink resource is valid;
- store the uplink resource configuration to be maintained after receiving the RRC connection release message;
- and
- control the transceiver to perform the transmission using the at least one periodic uplink resource to the network during the validity duration,
- wherein the at least one periodic uplink resource is valid at a specific cell, and
- wherein the transmission comprises a physical uplink shared channel (PUSCH) transmission.
