摘要:
A structured parity-check matrix H is proposed, wherein H is an expansion of a base matrix Hb. Base matrix Hb comprises a section Hb1 and a section Hb2. Section Hb2 comprises column hb having weight wh>=3 and H′b2 having a dual-diagonal structure with matrix elements at row i, column j equal to 1 for i=j, 1 for i=j+1, and 0 elsewhere. The 1's of hb and Hb1 are arranged such that one or more groups of the rows of Hb can be formed so that the rows of Hb within each group do not intersect. Further more, the rows of base matrix Hb can be permuted such that every two consecutive rows do not intersect.

摘要:
A structured parity-check matrix H is proposed, wherein H is an expansion of a base matrix Hb and wherein Hb comprises a section Hb1 and a section Hb2, and wherein Hb2 comprises a first part comprising a column hb having an odd weight greater than 2, and a second part comprising matrix elements for row i, column j equal to 1 for i=j, 1 for i=j+1, and 0 elsewhere. The expansion of the base matrix Hb uses identical submatrices for 1s in each column of the second part H′b2, and the expansion uses paired submatrices for an even number of 1s in hb.

A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted including a plurality of sequence elements intereleaved in time and frequency (610, 640). The synchronization channel signal sequence elements enable an initial acquisition and cell search method with low computational load by providing predetermined time domain symmetry (702, 704) for common sequence elements in OFDMA symbol periods (620, 660) for OFDMA symbol timing detection and frequency error detection in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.

A system [100] includes a base station [105] to communicate wireless data with at least one user terminal [125, 130] within a cell serviced by the base station [105]. A central backhaul access point [135] communicates wireless backhaul data with the base station [105]. At least a first portion of the wireless data and a second portion of the wireless backhaul data is communicated via Spatial Division Multiple Access (“SDMA”), and the first portion of the wireless data utilizes at least some same time-frequency resources as the second portion of the wireless backhaul data.
摘要:
A base station (105) includes a scheduler (220) to determine a location of a user terminal (110) within a cell (125) of a wireless system (100). The cell has a cell boundary (125). The scheduler (220) also determines a subcarrier frequency diverse resource allocation for a call on the user terminal (110) in response to the location of the user terminal (110) being within a predetermined distance from an edge of the cell boundary (125). The scheduler (220) further determines a subcarrier frequency selective resource allocation for the call on the user terminal (110) in response to the location of the user terminal (110) being beyond a predetermined distance from the edge of the cell boundary. The base station (105) also includes a transceiver (215) to transmit the call according to the subcarrier frequency diverse resource allocation and the subcarrier frequency selective resource allocation.

A base station (101) will request the transmission of quality information from a particular remote stations (102, 103) only when data is queued to be transmitted to the remote stations. Once a remote station begins the transmission of channel quality information, the transmission of such information continues until the data transmission is successfully delivered to the remote station. The base station receives the channel quality information and adjusts the modulation and coding of the remote stations accordingly. Where data is transmitted simultaneously to a plurality of remote stations, a set of queues (303) for the multiple remote stations is maintained, and based on queue status, a channel quality request messages is sent to a sub-set of remote stations with data queued.
