Abstract: A downlink resource block in an orthogonal frequency division multiplexing (OFDM) communication system can be shared among multiple wireless communication devices (WCDs) by assigning one or more orthogonal codes to each WCD. To transmit data to the WCDs using the downlink resource block, a base station may receive a data stream that includes respective data for each of the WCDs and encode each WCD's respective data with a respective orthogonal code assigned to that WCD to generate an encoded data stream. An OFDM transmitter in the base station may receive the encoded data stream and transmit the encoded data in the form of OFDM symbols in the downlink resource block. A WCD can receive the downlink resource block, recover the encoded data from the OFDM symbols, and use the one or more orthogonal codes assigned to it to recover the data for that WCD from the encoded data.

Abstract translation: 正交频分复用（OFDM）通信系统中的下行链路资源块可以通过向每个WCD分配一个或多个正交码来在多个无线通信设备（WCD）中共享。 为了使用下行​​链路资源块将数据发送到WCD，基站可以接收包括每个WCD的相应数据的数据流，并且用分配给该WCD的相应正交码对每个WCD的相应数据进行编码，以生成编码数据流 。 基站中的OFDM发射机可以接收编码数据流，并以下行链路资源块中的OFDM符号的形式发送编码数据。 WCD可以接收下行链路资源块，从OFDM符号恢复编码数据，并使用分配给它的一个或多个正交码从编码数据中恢复该WCD的数据。
