METHODS AND APPARATUSES FOR DATA TRANSMISSION AND RECEPTION
A network apparatus includes: a transmitter configured to transmit, to a terminal equipment, data scheduling control information including information used for indicating available time-frequency resources on one or more scheduled bandwidth resources, the available time-frequency resources being used by the terminal equipment for transmitting the uplink data; and a receiver configured to receive the uplink data, wherein the transmitter is further configured to transmit, to the terminal equipment, control information including first indication information and second indication information, the first indication information including a bitmap used for indicating one or more bandwidth resources, the one or more bandwidth resources being bandwidth resource(s) where the terminal equipment is allowed to share a channel occupancy time of a network device to transmit uplink data, the second indication information being used for indicating an uplink/downlink structure.
1 . A network apparatus comprising:
a transmitter configured to transmit, to a terminal equipment, data scheduling control information including information used for indicating available time-frequency resources on one or more scheduled bandwidth resources, the available time-frequency resources being used by the terminal equipment for transmitting the uplink data; and
a receiver configured to receive the uplink data, wherein
the transmitter is further configured to transmit, to the terminal equipment, control information including first indication information and second indication information, the first indication information including a bitmap used for indicating one or more bandwidth resources, the one or more bandwidth resources being bandwidth resource(s) where the terminal equipment is allowed to share a channel occupancy time of a network device to transmit uplink data, the second indication information being used for indicating an uplink/downlink structure.
2 . The network apparatus according to claim 1 , wherein
the receiver is configured to receive the uplink data on one or more unlicensed frequency bands, and
the transmitter is configured to transmit the control information on one or more unlicensed frequency bands or one or more licensed frequency bands.
3 . The network apparatus according to claim 1 , wherein
the receiver is configured to receive the uplink data on one or more unlicensed frequency bands, and
the transmitter is configured to transmit the data scheduling control information on one or more unlicensed frequency bands or one or more licensed frequency bands.
4 . The network apparatus according to claim 1 , further comprising
processor cirsuitry configured to control to detect a channel of an unlicensed frequency band to determine the one or more bandwidth resources.
5 . The network apparatus according to claim 1 , wherein the control information is transmitted after the data scheduling control information.
6 . The network apparatus according to claim 1 , wherein the control information is transmitted before the data scheduling control information.
7 . The network apparatus according to claim 1 , wherein
the receiver is further configured to receive the uplink data on a coincided resource of the one or more bandwidth resources and the available time-frequency resources.
8 . The network apparatus according to claim 1 , wherein
the one or more scheduled bandwidth resources are of a default size, or the one or more scheduled bandwidth resources are notified to the terminal equipment by a network device in at least one of the following manners:
indicating the scheduled bandwidth resource by the data scheduling control information;
configuring the scheduled bandwidth resource via higher layer signaling.
9 . The network apparatus according to claim 1 , wherein the control information is UE-specific control information.
10 . The network apparatus according to claim 1 , wherein the control information is common control information.
11 . The network apparatus according to claim 1 , wherein the control information is transmitted on at least one of the following: a set of resources of the one or more bandwidth resources, one of the one or more bandwidth resources, each of the one or more bandwidth resources, and a resource of a licensed frequency band pre-allocated by a network device.
12 . A terminal equipment comprising:
a receiver configured to receive, from a network device, data scheduling control information including information used for indicating available time-frequency resources on one or more scheduled bandwidth resources, the available time-frequency resources being used by the terminal equipment for transmitting the uplink data; and
a transmitter configured to transmit the uplink data to the network device, wherein
the receiver is configured to receive, from the network device, control information including first indication information and second indication information, the first indication information including a bitmap used for indicating one or more bandwidth resources, the one or more bandwidth resources being bandwidth resource(s) where the apparatus is allowed to share a channel occupancy time of the network device to transmit uplink data, the second indication information being used for indicating an uplink/downlink structure.
13 . The terminal equipment according to claim 12 , wherein the receiver is further configured to receive the control information after the data scheduling control information.
14 . The terminal equipment according to claim 12 , wherein the receiver is further configured to receive the control information before the data scheduling control information.
