Abstract

A primary wireless access node receives primary power headroom for User Equipment (UE). A secondary wireless access receives secondary power headroom for the UE and transfers the secondary power headroom to the primary wireless access node. The primary wireless access node compares the power primary headroom to the secondary power headroom to determine a primary uplink grant amount and a secondary uplink grant amount for the UE. The primary wireless access node grants primary uplink resources to the UE based on the primary uplink grant amount. The secondary wireless access node grants secondary uplink resources to the UE based on the secondary uplink grant amount. The wireless access nodes receive user data from the UE based on the uplink grant amounts.

Claims20

Dependent claims

A method of operating a wireless communication network to serve User Equipment (UE) over wireless uplinks, the method comprising:

a primary wireless access node wirelessly receiving primary power headroom for the UE on the primary wireless access node;
a secondary wireless access node wirelessly receiving secondary power headroom for the UE on the secondary wireless access node and transferring the secondary power headroom to the primary wireless access node;
the primary wireless access node comparing the primary power headroom to the secondary power headroom, determining a primary uplink grant amount and a secondary uplink grant amount for the UE based on the power headroom comparison, and transferring the secondary uplink grant amount to the secondary wireless access node;
the primary wireless access node granting primary uplink resources to the wireless UE based on the primary uplink grant amount and wirelessly receiving primary user data from the wireless UE using the primary uplink resources;
and
the secondary wireless access node granting secondary uplink resources to the wireless UE based on the secondary uplink grant amount and wirelessly receiving secondary user data from the wireless UE using the secondary uplink resources.

A wireless communication network to serve User Equipment (UE) over wireless uplinks, the wireless communication network comprising:

a primary wireless access node configured to wirelessly receive primary power headroom for the UE on the primary wireless access node;
a secondary wireless access node configured to wirelessly receive secondary power headroom for the UE on the secondary wireless access node and transfer the secondary power headroom to the primary wireless access node;
the primary wireless access node configured to compare the primary power headroom to the secondary power headroom, determine a primary uplink grant amount and a secondary uplink grant amount for the UE based on the power headroom comparison, and transfer the secondary uplink grant amount to the secondary wireless access node;
the primary wireless access node configured to grant primary uplink resources to the wireless UE based on the primary uplink grant amount and wirelessly receive primary user data from the wireless UE using the primary uplink resources;
and
the secondary wireless access node configured to grant secondary uplink resources to the wireless UE based on the secondary uplink grant amount and wirelessly receive secondary user data from the wireless UE using the secondary uplink resources.
