Abstract
The present disclosure provides a method for transmitting uplink information, including: determining a frequency band for carrier sensing and an allocation manner of uplink frequency domain resources by receiving a signaling or by predefining via a protocol; performing carrier sensing at the determined frequency band for carrier sensing; and transmitting uplink information in uplink frequency domain resources determined according to the allocation manner of uplink frequency domain resources when a carrier is idle. The present disclosure also provides a user equipment for transmitting uplink information.
Claims12
A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving, from a base station (BS), downlink control information (DCI) for scheduling of uplink data, wherein the DCI includes interlace allocation information and resource block (RB) set allocation information;
- performing a carrier sensing on a plurality of RB sets, wherein the plurality of RB sets is identified based on the RB set allocation information included in the DCI;
- and
- transmitting, to the BS, the uplink data on at least one RB of the plurality of RB sets, based on the interlace allocation information and a result of the carrier sensing on the plurality of RBs,
- wherein the RB set allocation information indicates the plurality of RB sets is consecutive RB sets corresponding to a frequency bandwidth for the carrier sensing, and
- wherein the interlace allocation information includes a bitmap indicating whether frequency domain resource allocation units is allocated to the UE, and a size of the bitmap is a number of the frequency domain resource allocation units.
A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver;
- and
