Also, to the point where one might wish to move away from or extend these default mappings, standardizing on new LCIDs for MAC control or other purposes is a slow and cumbersome process

Embodiment Construction

[0021] Before turning to the description, consider an example where an eNodeB (eNB) reserves a Logical Channel Identification (referred to as LCID) from a set of LCIDs that are predefined or specified for use in identifying logical channels at the MAC layer. Here, it should be understood that eNBs operate according to governing standards or technical specifications that traditionally limit the use of LCIDs by eNBs to "standard uses" as defined in the specifications. It should also be understood that "reserved" means reserving or designating or selecting an LCID for an alternate use.

[0022] Alternative uses are different from those prescribed by the control standard. That is, the control standard specifies that LCIDs are used to identify logical channels at the MAC layer or sublayers, however, in accordance with the teachings herein, the LCIDs are selected at least temporarily for alternate purposes.

[0023]Alternative usages extend the network and are compatible with alter...

Abstract

On the one hand, the teachings herein make effective use of previous efforts to provide new signaling mechanisms for communication networks to use defined identifiers according to applicable communication standards or protocols according to "standards", as opposed to standard uses, by temporarily reusing a or more of these identifiers for alternative uses. For example, a network base station or other node, knowing or learning that a given wireless device operating in the network is compatible with an alternate use, selects a given identifier and temporarily reassigns it to an alternate use, e.g., the alternate use Provides a new signaling mechanism between the network and compatible devices. These operations include repurposing restricted reuse scenarios to non-compliant devices involving compliant devices and avoiding conflicts involving non-compliant devices involving compliant devices that conflict with standard uses involving non-compliant devices.

Description

technical field [0001] The present invention relates to wireless communication networks and their controlling standards, and in particular to extending the signaling defined by such standards. Background technique [0002] In wireless communication networks such as those based on Long Term Evolution (LTE), specified by the Third Generation Partnership Project (3GPP), there are ) for certain data layer functions for large-scale communication. In particular, some data layer functions are designed for peer-to-peer control of transport channels and mapping between transport channels and logical channels. Example functions include those used by the Radio Resource Control (RRC) protocol and Medium Access Control (MAC) sublayer in 3GPP LTE. [0003] According to the Evolved Packet System or EPS defined by the 3GPP LTE architecture, the radio access network is called Evolved Universal Terrestrial Radio Access Network (E-UTRAN). E-UTRAN includes base stations, called eNodeBs or eN...
