Abstract
There is disclosed a User Equipment for a MulteFire wireless communication network. The User Equipment comprises processing circuitry and a transmitter, the User Equipment being adapted for utilizing the processing circuitry and the transmitter for performing a Listen-Before-Talk (LBT) procedure for one or more transmission bandwidths; transmitting Physical Uplink Shared CHannel (PUSCH) signaling in a PUSCH subframe on one or more interlaces within the one or more transmission bandwidths; and transmitting Sounding Reference Signaling on the one or more interlaces in the PUSCH subframe.
Claims16
A User Equipment for a MulteFire wireless communication network, the User Equipment comprising processing circuitry and a transmitter, the User Equipment being adapted for utilizing the processing circuitry and the transmitter for:
- performing a Listen-Before-Talk (LBT) procedure for one or more transmission bandwidths;
- transmitting Physical Uplink Shared CHannel (PUSCH) signaling in a PUSCH subframe on one or more interlaces within the one or more transmission bandwidths;
- and
- transmitting Sounding Reference Signaling on the one or more interlaces in the PUSCH subframe.
A method for operating a User Equipment in a MulteFire wireless communication network, the method comprising:
- performing a Listen-Before-Talk (LBT) procedure for one or more transmission bandwidths;
- transmitting Physical Uplink Shared CHannel (PUSCH) signaling in a PUSCH subframe on one or more interlaces within the one or more transmission bandwidths;
- and
- transmitting Sounding Reference Signaling on the one or more interlaces in the PUSCH subframe.
An Access Point for a MulteFire wireless communication network, the Access Point comprising processing circuitry and a receiver, the Access Point being adapted for utilizing the processing circuitry and the receiver for:
- estimating channel conditions based on Sounding Reference Signaling received from at least one User Equipment for the MulteFire wireless communication network;
- wherein receiving Sounding Reference Signaling comprises receiving Physical Uplink Shared CHannel, PUSCH, signaling in a PUSCH subframe on one or more interlaces, and receiving Sounding Reference Signaling on the one or more interlaces in the PUSCH subframe.
A method for operating an Access Point in a MulteFire wireless communication network, the method comprising:
- estimating channel conditions based on Sounding Reference Signaling received from at least one User Equipment for the MulteFire wireless communication network;
- wherein receiving Sounding Reference Signaling comprises receiving Physical Uplink Shared CHannel, PUSCH, signaling in a PUSCH subframe on one or more interlaces, and receiving Sounding Reference Signaling on the one or more interlaces in the PUSCH subframe.
