Abstract
The specification and drawings present a new method, system, apparatus and software product for varying a length of a radio link ID (RLID) of a user equipment for resource allocation in mobile communication systems. This allows the system to employ shorter RLID lengths than is necessary if all user equipments (UEs) in the active mode are uniquely identified simultaneously, thus providing considerable savings in the signaling resource on the physical layer.
Claims35
A method, comprising:
- assigning a radio link identifier responsive to a user equipment entering an active mode;
- assigning a short radio link identifier to said user equipment, wherein said short radio link identifier comprises a smaller number of digital bits than said radio link identifier;
- allocating resources related to said user equipment using said short radio link identifier for a first portion of subframes during said active mode;
- and
- allocating resources related to said user equipment using said radio link identifier for a second portion of subframes during said active mode.
2 more elements
An article of manufacture including a non-transitory computer-readable medium having instruction stored thereon that, if executed by a computing device, cause the computing device to perform operations comprising:
- assigning a radio link identifier responsive to a user equipment entering an active mode;
- assigning a short radio link identifier to said user equipment, wherein said short radio link identifier comprises a smaller number of digital bits than said radio link identifier;
- allocating resources related to said user equipment using said short radio link identifier for a first portion of subframes during said active mode;
- and
- allocating resources related to said user equipment using said radio link identifier for a second portion of subframes during said active mode.
2 more elements
A user equipment, comprising:
- an allocation obtaining block configured to:
- determine allocated resources related to said user equipment in an active mode using a short radio link identifier assigned to the user equipment during said active mode for a first portion of subframes;
- and
- determine allocated resources related to said user equipment in said active mode using a radio link identifier assigned to said user equipment during said active mode for a second portion of frames,
- wherein said short radio link identifier comprises a smaller number of digital bits than said radio link identifier.
2 more elements
A system, comprising:
- a network element configured to provide a downlink signal;
- and
- a user equipment assigned a radio link identifier and a short radio link identifier for use in an active mode, wherein said user equipment, responsive to said downlink signal, is configured to allocate resources related to said user equipment when in said active mode using said short radio link identifier for a first portion of subframes and using said radio link identifier for a second portion of subframes, wherein
- said short radio link identifier comprises a smaller number of digital bits than said radio link identifier.
1 more element
A network element, comprising:
- a radio link identifier assigning block, configured to assign a radio link identifier and a short radio link identifier to a user equipment in an active state,
- wherein said short radio link identifier comprises a smaller number of digital bits than said radio link identifier, and
- wherein said user equipment is configured to allocate resources related to said user equipment using said short radio link identifier for a first portion of subframes and using said radio link identifier for a second portion of subframes.
A user equipment, comprising:
- allocating means for:
- determining allocated resources related to said user equipment in an active mode using a short radio link identifier assigned to the user equipment during said active mode for a first portion of subframes;
- and
- determining allocated resources related to said user equipment in said active mode using a radio link identifier assigned to said user equipment during said active mode for a second portion of frames,
- wherein said short radio link identifier comprises a smaller number of digital bits than said radio link identifier.
2 more elements
A network element, comprising:
- assigning means for assigning a radio link identifier and a short radio link identifier to a user equipment responsive to said user equipment entering an active state,
- wherein said short radio link identifier comprises a smaller number of digital bits than said radio link identifier, and
- wherein said user equipment allocates resources related to said user equipment during said active state using said short radio link identifier for a first portion of subframes and using said radio link identifier for a second portion of subframes.
A method, comprising:
- assigning a radio link identifier to a user equipment for use in an active mode;
- assigning a short radio link identifier to said user equipment, wherein said short radio link identifier comprises a smaller number of digital bits than said radio link identifier;
- allocating resources related to said user equipment using said short radio link identifier during said active mode;
- and
- assigning, if a predetermined criterion is met, a pattern of subframes during which said short radio link identifier is valid for said user equipment,
- wherein said allocating resources related to said user equipment is performed using said short radio link identifier in said pattern of subframes during which said short radio link identifier is valid and using said radio link identifier for subframes not included in said pattern of subframes.
