Power control in a wireless network
View Patent ↗A network device may transmit a signal to a user equipment indicating that accumulation is enabled. The network device may transmit, when accumulation is enabled, power control information to the user equipment in a same physical channel as scheduling information. The power control information may include an accumulation power command.
1. A network device comprising:
a transmitter;
a receiver; and
a processor operatively coupled to the transmitter and the receiver;
wherein the processor is configured:
to cause the transmitter to transmit an indication to a user equipment (UE) that transmit power command (TPC) accumulation is enabled,
to cause the transmitter to transmit, on a single physical channel, scheduling information and power control information that includes a multi-level TPC command, and
to cause the receiver to receive, from the UE based on the transmitted scheduling information and the multi-level TPC command, an uplink signal.
2. The network device of claim 1 , wherein the multi-level TPC command has a value selected from a plurality of pre-defined values.
3. The network device of claim 1 , wherein the uplink signal is received on an uplink shared channel.
4. The network device of claim 1 , wherein the network device is any one of a Node-B or a base station.
5. A method performed by a network device, the method comprising:
transmitting, by the network device, an indication to a user equipment (UE) that transmit power command (TPC) accumulation is enabled;
transmitting, by the network device on a single physical channel, scheduling information and power control information that includes a multi-level TPC command; and
receiving, by the network device from the UE based on the transmitted scheduling information and the multi-level TPC command, an uplink signal.
6. The method of claim 5 , wherein the multi-level TPC command has a value selected from a plurality of pre-defined values.
7. The method of claim 5 , wherein the uplink signal is received on an uplink shared channel.
8. The method of claim 5 , wherein the network device is any one of a Node-B or a base station.
