Filed:

Oct 1, 2008

Appl. No.:

12/243398

Inventors:

Bazhong Shen - Irvine CA, US
Mark Kent - Vista CA, US

International Classification:

H04W 8/00

US Classification:

370328

Abstract:

Aspects of a method and system for determining a limited soft buffer size on transport blocks for rate matching are provided. A data stream may be processed for transmission between a base station (eNodeB) and a UE via HARQ procedures. A two-stage rate-matching algorithm may be used in the HARQ procedures. A limited virtual soft buffer size at the UE in the two-stage rate-matching algorithm may be calculated on site based on channel condition information, available channel bandwidth, number of layers in spatial multiplexing, and the capacity of the UE, respectively. The data stream may be first rate-matched to the calculated limited soft buffer size available at the UE, and forwarded for second stage rate-matching to an actual physical channel size determined by the base station. The amount of bits forwarded for second stage rate-matching may equal to the calculated limited virtual soft buffer size of the virtual soft buffer.

US Classification:

455411

Abstract:

Aspects of a method and system for service mobility via a femtocell infrastructure are provided. In this regard, a mobile cellular enabled communication device may detect a femtocell operable to deliver content for one or more services to the mobile cellular enabled communication device, where the one or more services may be provided via a set-top-box communicatively coupled to the femtocell. The mobile cellular enabled communication device may communicate a user profile to the femtocell, wherein information in the profile may be utilized by the set-top-box to authenticate and/or authorize access to the services by the mobile cellular enabled communication device and thus the mobile cellular enabled communication device may receive the content from the set-top-box based on the authentication and/or authorization. The content may comprise voice, video, data, text and/or still images. The mobile cellular enabled communication device may detect the femtocell by receiving one or broadcast messages from the femtocell.

Abstract:

Aspects of a method and system for servicing a plurality of users via a plurality of femtocells are provided. In this regard, a cellular enabled communication device may receive portions of a datastream from a plurality of femtocells, reconstruct the datastream from the received portions of the datastream, and process the reconstructed datastream for presentation to a user of the cellular enabled communication device. The received portions may be buffered in the cellular enabled communication device. The portions of the datastream may be associated with a plurality of CDMA channel access codes. The portions of the datastream may be received via a plurality of cellular frequencies. The portions of the datastream may be received during a plurality of TDMA timeslots. Portions of the datastream may be received from a cellular base station. Portions of the datastream may be received from a WiMAX base station.

US Classification:

370329

Abstract:

A Femtocell gateway is operable to determine resource usage information among associated Femtocells in a Femtocell network. The Femtocell gateway may be enabled to allocate resources for distributing traffic among the associated Femtocells based on the determined resource usage information comprising IP usage information, radio access usage, and/or physical layer capabilities among the Femtocells. The Femtocell gateway may be enabled to identify Femtocells with excess resources assigned and Femtocells with a need for additional resources to support a particular traffic based on the determined resource usage information. The Femtocell gateway is operable to allocate and/or reallocate at least a portion of excess resources to the Femtocells with the need for the additional resource to support the particular traffic. The Femtocells that share resources with other Femtocells in the Femtocell network is rewarded with credits. The particular traffic is redirected to the Femtocells with excess resources and distributed to destinations.
