Channel quality information feedback techniques for wireless system

Номер: CN103067128A
Автор: Yin Hujun, Srinivasan Roshni M.
Принадлежит:

The invention relates to channel quality information feedback techniques for wireless system. The 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.

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.

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. 1. A long term evolution (LTE) base station , comprising:circuitry to determine a channel quality indicator (CQI) feedback dimension value for an orthogonal frequency division multiple access (OFDMA) system, the CQI feedback dimension value to represent a number of resource blocks a subscriber station is to measure in order to provide CQI feedback information of a given level of CQI feedback granularity, the CQI feedback dimension value determined based on a probability of resource block assignment to subscriber stations in the OFDMA system, the circuitry to cause transmission of the CQI feedback dimension value, and receive a CQI feedback value representing channel quality measurements measured in accordance with the CQI feedback dimension value.2. The LTE base station of claim 1 , the circuitry to cause transmission of the CQI feedback dimension value to one or more subscriber stations.3. The LTE base station of claim 1 , the circuitry to receive a CQI feedback value representing channel quality measurements as measured by multiple subscriber stations.4. The LTE base station of claim 1 , the circuitry to receive a single CQI feedback value representing channel quality measurements across multiple resource blocks.5. The LTE base station of claim 1 , the circuitry to receive a single CQI feedback value representing a channel quality measurement of a single resource block.6. The LTE base station of claim 1 , the circuitry to increase ...

Wireless broadband resource allocation indexing

Номер: US20110141980A1
Автор: Huaning Nin, Hujun Yin, PING Wang, Roshni M. Srinivasan
Принадлежит: Intel Corp

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.
