Abstract

Techniques and apparatus for service-based transmit energy allocation are described. An example method that may be performed by a wireless communication device includes obtaining reserve information associated with services allocated to a set of antenna groups. Each antenna group is associated with at least one radio corresponding to at least one radio access technology (RAT). A reserve is determined for each radio, based at least in part on the reserve information, a set of services mapped to the radio, and a respective state associated with each of the set of services. A signal(s) is transmitted for at least one service using at least one radio associated with the at least one service and a transmit power determined based at least in part on a radio frequency (RF) exposure limit associated with the at least one radio and the reserve for the at least one radio.

First claim

1 . A method of wireless communication by a wireless device, comprising:
obtaining reserve information associated with a plurality of services allocated to a set of antenna groups, each antenna group of the set of antenna groups being associated with one or more radios corresponding to one or more radio access technologies (RATs); determining a reserve for each of the one or more radios, based at least in part on the reserve information, a set of services of the plurality of services mapped to the radio, and a respective state associated with each of the set of services; and transmitting one or more signals for at least one service of the plurality of services using at least one radio of the one or more radios associated with the at least one service and a transmit power determined based at least in part on a radio frequency (RF) exposure limit associated with the at least one radio and the reserve for the at least one radio.

2 . The method of claim 1 , wherein:
the reserve information indicates a plurality of minimum service reserves for each of the plurality of services; and each of the plurality of minimum service reserves is associated with a respective antenna group of the set of antenna groups.

3 . The method of claim 2 , wherein determining the reserve for each of the one or more radios comprises, for each radio:
determining a sum of the respective minimum service reserves that are associated with (i) the set of services mapped to the radio and (ii) the antenna group that includes the radio; and determining the reserve for the radio to be equal to the sum of the minimum service reserves.

4 . The method of claim 3 , wherein the set of services mapped to the radio includes one or more services having a respective state in active mode or park mode.

5 . The method of claim 2 , wherein determining the reserve for each of the one or more radios comprises, for a single service of the plurality of services mapped to a first radio of the one or more radios and a second radio of the one or more radios:
determining the reserve for the first radio to be equal to a first portion of a respective minimum service reserve for the single service; and determining the reserve for the second radio to be equal to a second portion of the respective minimum service reserve for the single service, wherein the first radio and the second radio are in the same antenna group.

6 . The method of claim 1 , wherein:
the reserve for each of the one or more radios is a minimum level of transmit power allocated to the respective radio for a time window associated with the RF exposure limit; and the reserve for each of the one or more radios is determined prior to a start of the time window.

7 . The method of claim 1 , wherein the reserve information indicates a respective priority for each of the plurality of services.

8 . The method of claim 7 , further comprising determining a priority for each of the one or more radios, based at least in part on the reserve information and the set of services mapped to the radio.

9 . The method of claim 8 , wherein:
the set of services comprises a single service mapped to a single radio of the one or more radios; and determining the priority for each of the one or more radios comprises determining the priority for the single radio to be equal to the priority of the single service.

10 . The method of claim 8 , wherein:
the set of services comprises a plurality of services mapped to a single radio of the one or more radios; and determining the priority for each of the one or more radios comprises:
determining which of the plurality of services has a highest priority; and
determining the priority for the single radio to be equal to the highest priority.

11 . The method of claim 8 , wherein:
the set of services comprises a single service mapped to a plurality of radios of the one or more radios; and determining the priority for each of the one or more radios comprises determining the priority for each of the radios to be equal to the priority of the single service.

12 . The method of claim 1 , wherein the at least one service is a single service that is mapped to a single radio of the one or more radios.

13 . The method of claim 1 , wherein the at least one service comprises at least two services mapped to a plurality of the one or more radios.

14 . The method of claim 1 , wherein the at least one service is a single service that is mapped to a plurality of the one or more radios.

15 . An apparatus for wireless communication, comprising:
one or more memories collectively storing computer-executable instructions; and one or more processors coupled to the one or more memories, the one or more processors being collectively configured to execute the computer-executable instructions to cause the apparatus to perform an operation comprising:
obtaining reserve information associated with a plurality of services allocated to a set of antenna groups, each antenna group of the set of antenna groups being associated with one or more radios corresponding to one or more radio access technologies (RATs);
determining a reserve for each of the one or more radios, based at least in part on the reserve information, a set of services of the plurality of services mapped to the radio, and a respective state associated with each of the set of services; and
transmitting one or more signals for at least one service of the plurality of services using at least one radio of the one or more radios associated with the at least one service and a transmit power determined based at least in part on a radio frequency (RF) exposure limit associated with the at least one radio and the reserve for the at least one radio.

16 . The apparatus of claim 15 , wherein:
the reserve information indicates a plurality of minimum service reserves for each of the plurality of services; and each of the plurality of minimum service reserves is associated with a respective antenna group of the set of antenna groups.

17 . The apparatus of claim 16 , wherein determining the reserve for each of the one or more radios comprises, for each radio:
determining a sum of the respective minimum service reserves that are associated with (i) the set of services mapped to the radio and (ii) the antenna group that includes the radio; and determining the reserve for the radio to be equal to the sum of the minimum service reserves.

18 . The apparatus of claim 17 , wherein the set of services mapped to the radio includes one or more services having a respective state in active mode or park mode.

19 . The apparatus of claim 16 , wherein determining the reserve for each of the one or more radios comprises, for a single service of the plurality of services mapped to a first radio of the one or more radios and a second radio of the one or more radios:
determining the reserve for the first radio to be equal to a first portion of a respective minimum service reserve for the single service; and determining the reserve for the second radio to be equal to a second portion of the respective minimum service reserve for the single service, wherein the first radio and the second radio are in the same antenna group.

20 . The apparatus of claim 15 , wherein:
the reserve for each of the one or more radios is a minimum level of transmit power allocated to the respective radio for a time window associated with the RF exposure limit; and the reserve for each of the one or more radios is determined prior to a start of the time wi
