US 9,872,258 B1 · Dynamic control of uplink transmission power attenuation based on roaming status

Abstract

Disclosed is a method and system for enabling user equipment devices (UEs) to apply less attenuation than may be specified more generally for UEs served by a base station of a wireless service provider. The base station may operate on a carrier band, serving UEs that are subscribers of the wireless service provider as well as UEs roaming in the base station's coverage area from another service provider. To avoid uplink transmission power leakage across the edges of the carrier band, the base station may broadcast a message to all the UEs notifying them to attenuate their respective transmission levels. In response, a UE may determine whether or not it is roaming to a wireless communication network of a different service provider. If the UE determines that it is not roaming, it may then attenuate its uplink transmission power by less than an amount indicated by the message.

Dependent claims

A method operable in a user equipment device (UE) that is a service subscriber of a wireless communication network of a first service provider, wherein the wireless communication network of the first service provider is configured for providing wireless services to UEs using air interface resources that span a wireless carrier band, the method comprising:

the UE receiving from a base station of the wireless communication network a message informing the UE to attenuate its uplink transmission power by a specified amount determined based on which of multiple portions of the wireless carrier band is allocated, at least in part, to the UE by the base station for uplink transmissions;
making a determination, by the UE, that the UE is not roaming to a wireless communication network of a different service provider;
and
in response to at least the determination, the UE attenuating its uplink transmission power by less than the specified amount.

1 more element

A user equipment device (UE) that is a service subscriber of a wireless communication network of a first service provider, wherein the wireless communication network of the first service provider is configured for providing wireless services to UEs using air interface resources that span a wireless carrier band, the UE comprising:

a transceiver;
one or more processors;
and
memory accessible to the one or more processors, and storing machine language instructions that, upon execution by the one or more processors, cause the UE to carry out operations including:
receiving from a base station of the wireless communication network a message informing the UE to attenuate its uplink transmission power by a specified amount determined based on which of multiple portions of the wireless carrier band is allocated, at least in part, to the UE by the base station for uplink transmissions,
making a determination that the UE is not roaming to a wireless communication network of a different service provider, and
in response to at least the determination, attenuating its uplink transmission power by less than the specified amount.

4 more elements

A non-transitory computer readable medium having stored thereon instructions that, upon executing by one or more processors of a user equipment device (UE), cause the UE to carry out operations, wherein the UE is a service subscriber of a wireless communication network of a first service provider, wherein the wireless communication network of the first service provider is configured for providing wireless services to UEs using air interface resources that span a wireless carrier band, and wherein the operations comprise:

receiving from a base station of the wireless communication network a message informing the UE to attenuate its uplink transmission power by a specified amount determined based on which of multiple portions of the wireless carrier band is allocated, at least in part, to the UE by the base station for uplink transmissions;
making a determination that the UE is not roaming to a wireless communication network of a different service provider;
and
in response to at least the determination, attenuating its uplink transmission power by less than the specified amount.
