Power control in a wireless network
View Patent ↗A wireless network for allocating resources and controlling transmit power is provided. Uplink resource allocation information and a multilevel transmit power command is sent to a user equipment (UE) on a single downlink physical channel. In response to the information, the UE sends information on an uplink channel.
1. A method performed by a wireless network, the method comprising:
transmitting, by the wireless network on a single downlink physical channel, a signal having both uplink resource allocation information and a multilevel transmit power command;
receiving, by a user equipment (UE), the signal;
transmitting, by the UE on an unlink channel, an uplink signal in association with the uplink resource allocation information, wherein a transmission power level of the uplink signal is based on the multilevel transmit power command, a determined pathloss, and a format of the uplink signal; and
receiving, by the wireless network on the unlink channel, the uplink signal.
2. The method of claim 1 , wherein the uplink channel is an uplink shared channel.
3. The method of claim 1 further comprising:
accumulating, by the UE, a plurality of multilevel transmit power commands.
4. The method of claim 1 further comprising:
transmitting, by the wireless network, a parameter;
receiving, by the UE, the parameter; and
determining, by the UE, whether to accumulate transmit power commands in response to the parameter.
5. The method of claim 1 , wherein the wireless network and the UE utilize code division multiple access (CDMA).
6. The method of claim 1 , wherein the single downlink physical channel or the uplink channel is each associated with a spreading factor or a code division multiple access (CDMA) code.
7. The method of claim 1 , wherein the wireless network or the UE is a time division duplex (TDD) device.
8. A wireless network, the wireless network characterized in that:
a network device comprising:
circuitry configured to transmit, on a single downlink physical channel, a signal having both uplink resource allocation information and a multilevel transmit power command; and
circuitry configured to receive an uplink signal; and
a user equipment (UE) comprising:
circuitry configured to receive the signal; and
circuitry configured to transmit, on an uplink channel, the uplink signal in association with the uplink resource allocation information; and
wherein a transmission power level of the uplink signal is based on the multilevel transmit power command, a determined pathloss, and a format of the uplink signal.
9. The wireless network of claim 8 , wherein the uplink channel is an uplink shared channel.
10. The wireless network of claim 8 , wherein the UE further comprises:
circuitry configured to accumulate a plurality of multilevel transmit power commands.
11. The wireless network of claim 8 , characterized in that:
the wireless network is further configured to transmit a parameter; and
the UE further comprises:
the circuitry is further configured to receive the parameter; and
circuitry configured to determine whether to accumulate transmit power commands in response to the parameter.
12. The wireless network of claim 8 , wherein the wireless network and the UE utilize code division multiple access (CDMA).
13. The wireless network of claim 8 , wherein the single downlink physical channel or the uplink channel is each associated with a spreading factor or a code division multiple access (CDMA) code.
14. The wireless network of claim 8 , wherein the network device or the UE is a time division duplex (TDD) device.
