Patents by Inventor Roshni M Srinivasan

Roshni M Srinivasan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9749995
    Abstract: The various inventive embodiments relate to arrangement of information elements (IEs) for persistent and/or dynamic allocations in a wireless broadband network and include optimization techniques to eliminate the repetitive information fields from the downlink (DL)-Persistent-IEs, uplink (UL)-Persistent-IEs, DL-IEs, and UL-IEs. Elimination of repetitive information fields reduces MAP overhead. In addition embodiments relate to methods to use the same hybrid automatic repeat request (HARQ) region to contain persistent as well as non-persistent allocations. The use of the same HARQ region for persistent as well as non-persistent allocations further reduces the MAP overhead as it requires a single header to define the HARQ region instead of the two headers that are required to define two different HARQ regions: one for persistent allocation and the second one for non-persistent allocations.

  • Patent number: 9066360
    Abstract: Channel quality information feedback techniques for a wireless system are described. An apparatus may comprise a base station having base station logic to determine a channel quality indicator feedback dimension value representing a number of resource blocks for an orthogonal frequency division multiple access system to be measured by a subscriber station based on a matching ratio value, and a transceiver to send the channel quality indicator feedback dimension value to the subscriber station. Other embodiments are described and claimed.

  • Patent number: 8300586
    Abstract: Wireless broadband resource allocation indexing is generally presented. In this regard a method is introduced comprising determining a total number of allowable continuous logical resource unit (LRU) allocations for a bandwidth, removing allowable allocations to generate a set of allocations that can be indexed with fewer bits than the total number of allowable allocations, and storing an index of the set of allocations in a memory. Other embodiments are also disclosed and claimed.

  • Patent number: 7933346
    Abstract: Embodiments of a base station and method for mitigating interference in a sectorized wireless communication network are generally described herein. Other embodiments may be described and claimed. In some embodiments, some partitions of subchannels are configured in accordance with the distributed subcarrier permutation scheme for use within each sector of a base station, and one or more partitions of subchannels is configured in accordance with the contiguous subcarrier scheme for use within each sector of the base station.
