Abstract
In one aspect, a wireless device receives, from a wireless network node, two or more semi-persistent scheduling, SPS, configurations, each of the SPS configurations defining a plurality of periodic transmission opportunities for the wireless device, at least two of the two or more SPS configurations having different periods for the periodic transmission opportunities. The wireless device then transmits data corresponding to a first traffic type or a first radio bearer according to a first one of the two or more SPS configurations and transmitting data corresponding to a second traffic type or a second radio bearer according to a second one of the two or more SPS configurations.
Claims22
A method, in a wireless device, the method comprising:
- receiving, from a wireless network node, a first and a second semi-persistent scheduling (SPS) configuration, each of the first and the second SPS configurations defining a plurality of periodic transmission opportunities for the wireless device and the first SPS configuration being associated to a first V2x traffic type and the second SPS configuration being associated to a second specific V2x traffic type, the first and the second SPS configurations having different periods for the periodic transmission opportunities;
- receiving, from the wireless network node, information defining, for each of the first and second SPS configurations, a periodic uplink resource for sending intent-to-use indications or no-intent-to-use indications for the corresponding SPS configuration;
- transmitting, to the wireless network node, an acknowledgement to use the first and/or the second SPS configuration;
- and
- transmitting data corresponding to the first V2x traffic type according to the first SPS configuration associated to the first V2x traffic type and transmitting data corresponding to a second V2x traffic type according to the second SPS configuration associated to the second V2x traffic type.
A method, in a wireless network node, comprising:
- transmitting, to a wireless device, a first and a second semi-persistent scheduling (SPS) configuration, each of the first and the second SPS configurations defining a plurality of periodic transmission opportunities for the wireless device and the first SPS configuration being associated to a first V2x traffic type and the second SPS configuration being associated to a second V2x traffic type, the first and the second SPS configuration having different periods for the periodic transmission opportunities;
- transmitting, to the wireless device, information defining, for each of the first and second SPS configurations, a periodic uplink resource for the wireless device to use for sending intent-to-use indications or no-intent-to-use indications for the corresponding SPS configuration;
- receiving, from the wireless device, an acknowledgement to use the first and/or the second SPS configuration;
- and
- receiving data corresponding to the first V2x traffic type according to the first SPS configuration associated to the first V2x traffic type and receiving data corresponding to the second traffic type according to the second SPS configuration associated to the second V2x traffic type.
A wireless device comprising a radio transceiver and a processing circuit, wherein the processing circuit is configured to control the radio transceiver to:
- receive, from a wireless network node, a first and a second semi-persistent scheduling (SPS) configuration, each of the first and the second SPS configurations defining a plurality of periodic transmission opportunities for the wireless device and the first SPS being associated to a first V2x traffic type and the second SPS configuration being associated to a second V2x traffic type, the first and the second SPS configurations having different periods for the periodic transmission opportunities;
- receive, from the wireless network node, information defining, for each of the first and second SPS configurations, a periodic uplink resource for sending intent-to-use indications or no-intent-to-use indications for the corresponding SPS configuration;
- transmit, to the wireless network node, an acknowledgement to use the first and/or the second SPS configuration;
- and
- transmit data corresponding to the first V2x traffic type according to the first SPS configurations associated to the first V2x traffic type and transmit data corresponding to the second V2x traffic type according to the second SPS configuration associated to the second V2x traffic type.
A wireless network node comprising a radio transceiver and a processing circuit, wherein the processing circuit is configured to control the radio transceiver to:
