Abstract
A method for uplink power control is described. A user equipment (UE) power class may be determined. An uplink multiple access scheme may also be determined. The maximum transmission power for the UE may further be determined according to the determined uplink multiple access scheme and the UE power class.
Claims53
A method for uplink power control, the method comprising:
- determining a user equipment (UE) power class;
- determining an uplink multiple access scheme;
- and
- determining the maximum transmission power for the UE according to the determined uplink multiple access scheme and the UE power class.
A user equipment (UE) that is configured for uplink power control, the UE comprising:
- a processor;
- memory in electronic communication with the processor;
- instructions stored in the memory, the instructions being executable to:
- determine the UE power class;
- determine an uplink multiple access scheme;
- and
- determine the maximum transmission power for the UE according to the determined uplink multiple access scheme and the UE power class.
A base station that is configured for uplink power control in a wireless communications system, the base station comprising:
- a processor;
- memory in electronic communication with the processor;
- instructions stored in the memory, the instructions being executable to:
- determine a location of a user equipment (UE);
- determine the UE power class;
- determine an uplink multiple access scheme to be used by the UE;
- select a format for downlink control information (DCI), wherein the format of the DCI corresponds to the uplink multiple access scheme and the UE power class;
- and
- transmit the DCI to the UE.
A computer-readable medium comprising executable instructions for:
- determining a user equipment (UE) power class;
- determining an uplink multiple access scheme;
- and
- determining the maximum transmission power for the UE according to the determined uplink multiple access scheme and the UE power class.
A method for uplink power control, the method comprising:
- receiving a downlink control indicator (DCI);
- determining the number of chunks of resource blocks (RBs) in the DCI format;
- determining the value for an uplink maximum transmission power limiting factor according to the number of chunks of RBs, wherein the uplink maximum transmission power limiting factor is an uplink multiple access scheme dependent value used by the UE to limit the maximum transmission power for the UE;
- determining an uplink multiple access scheme;
- and
- determining the maximum transmission power for the UE according to the determined uplink multiple access scheme and the uplink maximum transmission power limiting factor.
