Abstract
Señalización de información de asistencia para equipos de usuario en una red inalámbrica. En general, esta memoria descriptiva da a conocer un aparato y procedimientos para mejorar la señalización de información de asistencia para equipos de usuario (UE) en una red inalámbrica. El dispositivo de UE puede incluir un circuito de procesamiento configurado para generar un mensaje de información de asistencia, que incluye un indicador de preferencia de potencia (Power Preference Indicator, PPI) e información de estado de movilidad (Mobility State Information, MSI), estando asociados el PPI y la MSI al UE; un módulo de generación de señales configurado para generar una señal de elemento de control (Control Element, CE) de la capa de control de acceso al medio (Medium Access Control, MAC), incluyendo la señal MAC CE el mensaje de información de asistencia; y un circuito transmisor configurado para transmitir la señal MAC CE a un nodo B evolucionado (evolved Node B, eNB) de una red inalámbrica asociada con el UE, transmitiéndose la señal MAC CE sobre un canal compartido de enlace ascendente (Uplink Shared Channel, UL-SCH). El mensaje de información de asistencia también puede ser generado como un mensaje de control de recursos de radio (RRC) y transmitido sobre un canal de control dedicado de enlace ascendente (Uplink Dedicated Control Channel, UL-DCCH).
Description
para cada evento de activación de información de asistencia (por ejemplo, una transición del UE desde un estado inactivo o un cambio en los ajustes de las preferencias de potencia del UE).
5 La figura 3 ilustra una estructura de mensajes 300 asociada con una forma de realización a título de ejemplo conforme a la presente memoria descriptiva; Una señal CE de la capa MAC puede incluir un encabezado MAC CE y una carga útil opcional. Se muestra un formato de encabezado MAC CE existente 302, que incluye un identificador de canal lógico (Logic Channel Identifier, LCID) en los bits 3-7. Los bits 0 y 1 están reservados y el bit 2 es un bit
10 de extensión utilizado para indicar la presencia de un encabezado de longitud extendida (usando octetos adicionales). Los LCID comprendidos en el intervalo de entre 01011 y 11000, ambos inclusive, están reservados, por lo que uno o más de estos valores se puede utilizar en un nuevo formato de encabezado MAC CE para indicar que la señal MAC CE se utiliza para transmitir información de asistencia (Assistance Information, AI). Por ejemplo, un
15 valor de LCID de 10111 puede indicar que el nuevo encabezado MAC CE 304 incluye una MSI en el bit 0. Como otro ejemplo, un valor de LCID de 11000 puede indicar que el nuevo encabezado MAC CE 306 incluye un PPI en el bit 0. Como ejemplo adicional, otro valor de LCID seleccionado del intervalo reservado puede indicar que el nuevo encabezado MAC CE 308 incluye tanto una MSI en el bit 0 como un PPI en el bit 1. Como otro ejemplo adicional,
20 otro valor de LCID seleccionado del intervalo reservado puede indicar que el nuevo encabezado MAC CE 310 viene acompañado de una carga útil de un solo octeto 312, 314 o
316. Las cargas útiles pueden incluir un bit de MSI, un bit de PPI o ambos. En algunas formas de realización, la carga útil puede permitir que el PPI y/o la MSI estén representados por 2 o más bits (no mostrados) con el fin de proporcionar niveles adicionales dentro de su
25 respectivo intervalo de valores.
La figura 4 ilustra un diagrama de flujo de mensajes 400 de una forma de realización a título de ejemplo conforme a la presente memoria descriptiva; El diagrama de flujo de mensajes 400 ofrece un ejemplo de tratamiento de la información de asistencia para UE entre el UE

combinación, sistema de circuitos cableados, sistema de circuitos programables, sistema de circuitos de máquinas de estado y/o el firmware que almacena instrucciones ejecutadas por los sistema de circuitos programables. Es posible realizar una aplicación como código o instrucciones que pueden ser ejecutadas en un sistema de circuitos programables, tales
5 como un procesador central u otro tipo de circuitos programables. Un módulo, tal como se usa en cualquier forma de realización de este documento, se puede realizar en forma de un sistema de circuitos. El sistema de circuitos se puede realizar como un circuito integrado, tal como un chip de circuito integrado.
10 Así pues, la presente memoria descriptiva da a conocer un aparato y procedimientos para mejorar la señalización de información de asistencia para equipos de usuario (UE) en una red inalámbrica.
De acuerdo con un aspecto, se da a conocer un UE. El UE puede incluir un circuito de
15 procesamiento configurado para generar un mensaje de información de asistencia que comprende un PPI e información de estado de movilidad MSI, estando asociados dicho PPI y dicha MSI al UE. El UE de este ejemplo también puede incluir un módulo de generación de señales configurado para generar una señal CE de la capa MAC, incluyendo dicha señal MAC CE el mensaje de información de asistencia. El UE de este ejemplo puede incluir
20 además un circuito transmisor configurado para transmitir la señal MAC CE a un eNB de una red inalámbrica asociada con el UE, transmitiéndose la señal MAC CE sobre un UL-SCH.
Otro ejemplo de UE incluye los componentes anteriores y además incluye un circuito receptor configurado para recibir un mensaje RRCConnectionReconfiguration del eNB en
25 respuesta a la transmisión de la señal MAC CE, comprendiendo el mensaje RRCConnectionReconfiguration parámetros de configuración DRX.
Otro ejemplo de UE incluye los componentes anteriores y además incluye un circuito temporizador configurado para retrasar la transmisión de la señal MAC CE de tal manera
13
preferencia de potencia del UE, siendo el estado un estado de configuración de potencia inferior o un estado de configuración de latencia inferior.
Otro ejemplo de UE incluye los componentes anteriores y el PPI representa un cambio del 5 estado de preferencia de potencia del UE, el cambio de estado entre un estado de configuración de potencia inferior y un estado de configuración de latencia inferior.
Otro ejemplo de UE incluye los componentes anteriores y la MSI representa una tasa de traspaso asociada con un estado conectado del UE y una tasa de reselección de célula
10 asociada con un estado inactivo del UE.
Otro ejemplo de UE incluye los componentes anteriores y además incluye una memoria acoplada al circuito de procesamiento, un sistema de I/O acoplado al circuito de procesamiento y una pantalla táctil acoplada al sistema de I/O.
15 De acuerdo con otro aspecto, se da a conocer un procedimiento. El procedimiento puede incluir la determinación de una preferencia de potencia para un UE. El procedimiento de este ejemplo puede incluir la determinación de un estado de movilidad para el UE, representando el estado de movilidad una tasa de traspaso asociada con un estado conectado del UE y
20 una tasa de reselección de célula asociada con un estado inactivo del UE; El procedimiento de este ejemplo puede incluir además la generación de un mensaje de información de asistencia para UE, incluyendo el mensaje la preferencia de potencia y el estado de movilidad. El procedimiento de este ejemplo puede incluir además la transmisión del mensaje de información de asistencia para UE a un eNB de una red inalámbrica asociada
25 con el UE.
Otro ejemplo de procedimiento incluye las operaciones anteriores e incluye además la transmisión del mensaje de información de asistencia para UE como una señal CE de la capa MAC sobre un UL-SCH.
