Transmitting a type 2 power headroom value for a primary cell
A wireless device transmits a Type 2 power headroom value, for a primary cell, in response to a physical uplink control channel (PUCCH) secondary cell being activated.
1. A method comprising:
receiving, by a wireless device, one or more parameters indicating whether simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission is configured for a PUCCH secondary cell; and
transmitting a power headroom report, wherein in response to the PUCCH secondary cell being activated, the power headroom report comprises:
a first Type 2 power headroom value for a primary cell; and
a second Type 2 power headroom value for the PUCCH secondary cell.
2. The method of claim 1 , further comprising receiving, before the transmitting, a first parameter indicating simultaneous PUCCH and PUSCH transmission is not configured for the primary cell of a plurality of cells, wherein the plurality of cells comprise the primary cell and the PUCCH secondary cell.
3. The method of claim 2 , wherein during the transmitting, the primary cell is not configured with the simultaneous PUCCH and PUSCH transmission.
4. The method of claim 1 , further comprising:
receiving, before the transmitting, a first parameter indicating whether simultaneous PUCCH and PUSCH transmission is configured for the primary cell of a plurality of cells, the plurality of cells comprising the primary cell and the PUCCH secondary cell; and
wherein a power headroom report comprises, independent of the first parameter, the first Type 2 power headroom value.
5. The method of claim 1 , further comprising receiving an activation command indicating activation of the PUCCH secondary cell prior to the transmission of the first Type 2 power headroom value.
6. The method of claim 1 , further comprising:
measuring, by the wireless device, one or more path loss values employing signals received on one or more pathloss reference cells; and
determining one or more values of the power headroom report employing the one or more path loss values.
7. The method of claim 1 , wherein the power headroom report comprises one or more Type 1 power headroom values.
8. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive one or more parameters indicating whether simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission is configured for a PUCCH secondary cell; and
transmit a power headroom report, wherein in response to the PUCCH secondary cell being activated, the power headroom report comprises:
a first Type 2 power headroom value for a primary cell; and
a second Type 2 power headroom value for the PUCCH secondary cell.
9. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive, before the transmitting, a first parameter indicating simultaneous PUCCH and PUSCH transmission is not configured for the primary cell of a plurality of cells, wherein the plurality of cells comprise the primary cell and the PUCCH secondary cell.
10. The wireless device of claim 9 , wherein during the transmitting, the primary cell is not configured with the simultaneous PUCCH and PUSCH transmission.
11. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to:
receive, before the transmitting, a first parameter indicating whether simultaneous PUCCH and PUSCH transmission is configured for the primary cell of a plurality of cells, the plurality of cells comprising the primary cell and the PUCCH secondary cell; and
wherein a power headroom report comprises, independent of the first parameter, the first Type 2 power headroom value.
12. The wireless device of claim 8 , further comprising receiving an activation command indicating activation of the PUCCH secondary cell prior to the transmission of the first Type 2 power headroom value.
13. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to:
measure one or more path loss values employing signals received on one or more pathloss reference cells; and
determine one or more values of the power headroom report employing the one or more path loss values.
14. A base station comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the base station to:
transmit one or more parameters indicating whether simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission is configured for a PUCCH secondary cell; and
receive a power headroom report, wherein in response to the PUCCH secondary cell being activated, the power headroom report comprises:
a first Type 2 power headroom value for a primary cell; and
a second Type 2 power headroom value for the PUCCH secondary cell.
