Abstract

An uplink grant is received. The uplink grant comprises: a field indicating a number of consecutive uplink subframes; an assignment of resource blocks comprising subcarriers; and a power control command. A determination is made of a transmission power of transport blocks in each subframe of the consecutive uplink subframes based on the power control command. The transmission power in each subframe is adjusted based on a total transmit power in each subframe exceeding a power value in each subframe. Transport blocks are transmitted, using the transmission power, via the subcarriers across each of the consecutive uplink subframes.

Claims (40)

1. A method comprising:

transmitting, to a wireless device, an uplink grant message of Physical Uplink Shared Channel (PUSCH) transmission in a Licensed Assisted Access (LAA) cell, comprising:

a field indicating a number of uplink subframes allocated for a PUSCH transmission;

an assignment of resource blocks corresponding to the uplink subframes; and

a power control command;

receiving PUSCH transmission in each subframe of the uplink subframes, which is transmitted using the first transmission power in the each subframe if a first transmission power of the PUSCH transmission in the each subframe does not exceed a maximum allowed power value in the each subframe; and

receiving PUSCH transmission in the each subframe, which is transmitted using a second transmission power which does not exceed the maximum allowed power value if the first transmission power in the each subframe exceeds the maximum allowed power value in the each subframe,

wherein the first transmission power of the PUSCH transmission in the each subframe is determined based on the power control command.

2. The method of claim 1 , wherein the uplink grant message further comprises:

a modulation and coding scheme;

a hybrid automatic repeat request (HARQ) identifier;

a redundancy version (RV); or

a new data indicator (NDI).

3. The method of claim 1 , wherein the number of the uplink subframes is less than a number of hybrid automatic repeat request (HARQ) processes supported by a wireless device.

4. The method of claim 1 , wherein the first transmission power is based on a measured pathloss value.

5. The method of claim 1 , wherein the first transmission power is based on a same closed loop adjustment factor, the closed loop adjustment factor calculated based on the power control command.

6. The method of claim 1 , wherein the PUSCH transmission is associated with an asynchronous hybrid automatic repeat request (HARQ) process.

7. The method of claim 1 , wherein the each subframe of the uplink subframes is associated with a hybrid automatic repeat request (HARQ) identifier, the HARQ identifier depending on a position of a subframe in the uplink subframes.

8. The method of claim 1 , further comprising receiving a sounding reference signal (SRS) in a subframe of the uplink subframes, wherein a transmission power of the SRS is calculated employing the power control command.

9. 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 an uplink grant message of Physical Uplink Shared Channel (PUSCH) transmission in a Licensed Assisted Access (LAA) cell, comprising:

a field indicating a number of uplink subframes allocated for a PUSCH transmission;

an assignment of resource blocks corresponding to the uplink subframes; and

a power control command;

receive PUSCH transmission in each subframe of the uplink subframes, which is using a first transmission power of the PUSCH transmission in the each subframe if the first transmission power in the each subframe does not exceed a maximum allowed power value in the each subframe; and

receive PUSCH transmission in the each subframe, which is transmitted using a second transmission power which does not exceed the maximum allowed power value if the first transmission power in the each subframe exceeds the maximum allowed power value in the each subframe,

wherein the first transmission power of the PUSCH transmission in the each subframe is determined based on the power control command.

10. The base station of claim 9 , wherein the uplink grant message further comprises:

a modulation and coding scheme;

a hybrid automatic repeat request (HARQ) identifier;

a redundancy version (RV); or

a new data indicator (NDI).

11. The base station of claim 9 , wherein the number of the uplink subframes is less than a number of hybrid automatic repeat request (HARQ) processes supported by a wireless device.

12. The base station of claim 9 , wherein the first transmission power is based on a measured pathloss value.

13. The base station of claim 9 , wherein the first transmission power is based on a same closed loop adjustment factor, the closed loop adjustment factor calculated based on the power control command.

14. The base station of claim 9 , wherein the PUSCH transmission is associated with an asynchronous hybrid automatic repeat request (HARQ) process.

15. The base station of claim 9 , wherein the each subframe is associated with a hybrid automatic repeat request (HARQ) identifier, the HARQ identifier depending on a position of a subframe in the uplink subframes.

16. The base station of claim 9 , wherein the instructions, when executed by the one or more processors, further cause the base station to receive a sounding reference signal (SRS) in a subframe of the uplink subframes, wherein a transmission power of the SRS is calculated employing the power control command.
