Abstract
Various arrangements for performing uplink grant-free transmissions are presented herein. An instance of user equipment (UE) may determine data that is to be transmitted using a grant-free (GF) uplink transmission to a base station of a cellular network. The UE may select a first GF resource block and a second GF resource block. The UE may transmit a GF transmission that comprises a data payload and a first pointer at the first GF resource block. The first pointer may refer to the second GF resource block.
Claims15
A method for performing uplink grant-free transmissions, the method comprising:
- determining, by a first user equipment (UE), data that is to be transmitted using a grant-free uplink transmission to a base station of a cellular network;
- selecting, by the first UE, a first grant-free resource block, wherein:
- a plurality of grant-free resource blocks define a plurality of subcarrier frequencies, a plurality of timeslots, or both for data to be transmitted to the base station of the cellular network without a reservation;
- selecting, by the first UE, a second grant-free resource block;
- and
- transmitting, by the first UE, a grant-free transmission that comprises a data payload, a first pointer, and a second pointer at the first grant-free resource block, wherein:
- the first pointer refers to the second grant-free resource block;
- and
- the second pointer refers to the first grant-free resource block and is indicative of the data payload not being transmitted on any later grant-free resource block.

A system that performs uplink grant-free transmissions, the system comprising:
- a cellular network comprises a plurality of base stations, the plurality of base stations comprising a base station;
- a plurality of user equipment (UE), wherein a first UE of the plurality of UE is configured to:
- determine data that is to be transmitted using a grant-free uplink transmission to the base station of the cellular network;
- select a first grant-free resource block, wherein:
- a plurality of grant-free resource blocks define a plurality of subcarrier frequencies, a plurality of timeslots, or both for data to be transmitted to the base station of the cellular network without a reservation;
- select a second grant-free resource block;
- and
- transmit a grant-free transmission that comprises a data payload, a first pointer, and a second pointer at the first grant-free resource block, wherein:
- the first pointer refers to the second grant-free resource block;
- and
- the second pointer refers to the first grant-free resource block and is indicative of the data payload not being transmitted on any later grant-free resource block.
