Abstract
A method of operating a network node includes preparing a command that activates or releases semi-persistent scheduling, SPS, of a group-common SPS transmission for a group of wireless devices, and transmitting the command to a wireless device in the group of wireless devices. A method of operating a wireless device includes receiving a command that activates or releases SPS of a group-common SPS transmission, and activating or releasing the group-common SPS transmission in response to the command. Related network nodes and wireless devices are disclosed.
Claims24
A method of operating a network node, comprising:
- preparing a command that activates or releases semi-persistent scheduling, SPS, of a group-common SPS transmission for a group of wireless devices, wherein the command comprises a slot index that identifies a time slot at which the group-common SPS transmission was activated, wherein the slot index identifies a time slot in which an original activation of the group-common SPS transmission was transmitted, and wherein the slot index corresponds to a time slot that is earlier than a time slot in which the command is transmitted to a wireless device in the group of wireless devices;
- and
- transmitting the command to the wireless device.
A method of operating a wireless device, comprising:
- receiving a command that activates or releases semi-persistent scheduling, SPS, of a group-common SPS transmission for a group of wireless devices, wherein the command comprises a slot index that identifies a time slot at which the group-common SPS transmission was activated, wherein the slot index identifies a time slot in which an original activation of the group-common SPS transmission was transmitted, and wherein the slot index corresponds to a time slot that is earlier than a time slot in which the command is transmitted to the wireless device;
- and
- activating or releasing the group-common SPS transmission in response to the command.
