摘要： An access device receives content from a broadband IP network to be communicated to a wireless handset over a radio access network (RAN). The access device acquires a user profile utilized in the radio network for the wireless handset. Based on the acquired user profile, the access device determines transmission parameters utilized for communicating the received content to the wireless handset using an air interface protocol over the radio access network. A security level and/or a security protocol, a transcoding mechanism, and/or transmission bit rate are determined based on the acquired user profile. A resolution, transmission bit rate, coding structure, security protocol and/or security level for transmitting the received content to the wireless handset are adjusted based on the acquired user profile. Alternately, the access device is enabled to receive content from the wireless handset using a transmission profile determined based on user profile of the wireless handset.

摘要： Aspects of a method and system for a transmitting antenna selection failure recover mode are presented. Aspects of the system may include a transmitting mobile terminal that enables selection of a sequence of protocol data units (PDU), for example a sequence of sounding frames, which may be transmitted during an antenna selection procedure. During transmission of the selected PDU sequence, the transmitting mobile terminal may receive an antenna selection failure indication frame. The transmitting mobile terminal may enable retransmission of at least one previously transmitted PDU in the PDU sequence based on the failure indication. Transmission of subsequent PDUs in the PDU sequence may resume after the retransmission. Alternatively, upon receipt of the failure indication frame the transmitting mobile terminal may restart the selected frame sequence from the beginning, or may select a subsequent PDU frame sequence.

摘要： Aspects of a method and system for an alternating channel delta quantizer for 2×2 MIMO pre-coders with finite rate channel state information feedback may include quantizing a change in channel state information in a 2×2 MIMO pre-coding system onto a codebook using a cost function, and alternating the codebook between two codebooks, each of which comprises one or more unitary matrices. The channel state information may be a matrix V that may be generated using Singular Value Decomposition (SVD) or Geometric Mean Decomposition (GMD). The cost function f(A) may be defined by the following relationship: f  ( A ) = ( 1 N  ∑ j = 1 N   a jj  2 ) where A is a matrix of size N by N and aij is element (i,j) of matrix A. The one or more unitary matrices may be generated from a first matrix and a second matrix. The first matrix and the second matrix may be generated using a Givens decomposition.
