Abstract
According to an aspect of the present disclosure, a method includes transmitting, by a network entity, at least one downlink control signal to a user equipment. The downlink control signal comprises a current slot format indicator and a further indicator. The current slot format indicator indicates at least one slot format combination. The further indicator comprises one or more of: at least one offset, at least one applicability indication, at least one next slot format indicator, and at least one indication of at least one channel occupancy time ending.
Claims20
An apparatus, comprising:
- at least one processor, and
- at least one memory including computer program code;
- the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- receive at least one downlink control signal from a network device, the downlink control signal comprising a current slot format indicator and a further indicator, the current slot format indicator indicating at least one slot format combination and the further indicator comprising an ending indication indicating where channel occupancy time ends;
- determine, based on the current slot format indicator and the further indicator, a first valid slot and an end of the channel occupancy time, and
- discontinue monitoring downlink control information from the network device in a slot after the last slot indicated by the ending indication.
An apparatus, comprising:
- at least one processor, and
- at least one memory including computer program code;
- the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- transmit at least one downlink control signal to a terminal device, the downlink control signal comprising a current slot format indicator and a further indicator, the current slot format indicator indicate at least one slot format combination and the further indicator comprising an ending indication indicating where channel occupancy time ends,
- wherein a combination of a plurality of indications included in the further indicator indicates jointly:
- 1) a first valid slot or a first slot where the current slot format indicator is configured to be applied, and 2) at least one last valid slot format.
A method, comprising:
- receiving, by a terminal device, at least one downlink control signal from a network device, the downlink control signal comprising a current slot format indicator and a further indicator, the current slot format indicator indicating at least one slot format combination and the further indicator comprising an ending indication indicating where channel occupancy time ends;
- determining, based on the current slot format indicator and the further indicator, a first valid slot and an end of the channel occupancy time;
- and
- discontinuing monitoring downlink control information from the network device in a slot after the last slot indicated by the ending indication.
