    Abstract: METHODS AND APPARATUSES TO POWER OFF A MODEM RECEIVER OR COMPONENTS OF THE RECEIVER AT A TIME PRIOR TO THE END OF THE FRAME BASED ON DATA IN THE FRAME BEING RECEIVED AND PROPERLY DECODED BEFORE THE END OF THE FRAME. IN AN ASPECT, THE APPARATUSES AND METHODS PROVIDE POWER SAVING IN A WIRELESS DEVICE, AND INCLUDE RECEIVING (21) DATA WITHIN A FRAME AT A USER EQUIPMENT (10, 550), DETERMINING (22) WHETHER ALL PAYLOAD PACKET DATA HAS BEEN CORRECTLY DECODED PRIOR TO AN END OF THE FRAME, AND POWERING DOWN (26) A RECEIVER COMPONENT FOR A PORTION OF A REMAINDER OF THE FRAME IN RESPONSE TO DETERMINING THAT ALL PAYLOAD PACKET DATA HAS BEEN CORRECTLY DECODED AND WHERE A FIRST TIME PERIOD TO A NEXT SCHEDULED OVERHEAD BIT TRANSMISSION PERIOD OF A SLOT IN THE FRAME IS GREATER THAN A SECOND TIME PERIOD CORRESPONDING TO A WARM-UP PERIOD FOR THE RECEIVER COMPONENT.

    Abstract: A data-optimized communication system provides support for legacy access terminals, such as access terminals operating under the 1xEV-DO standard. The system also supports multiple-input multiple-output (MIMO) communications with access terminals configured to support MIMO. A number of MIMO spatial signatures are predefined or negotiated. MIMO rank and an identifier of the spatial signature determined at the MIMO access terminal are sent on the I-Branch and Q-Branch of the existing 1xEV-DO structure. In one embodiment, 1-bit rank and 3-bit spatial signature are transmitted through the I-Branch as a 4-bit symbol, replacing the data rate control (DRC) channel. In another embodiment, a 4-bit spatial signature is transmitted through the I-Branch, also replacing the DRC channel. A 2-bit rank is transmitted together with a 4-bit DRC channel through the Q-Branch. The 2-bit rank and the DRC channel can be distinguished because they are sent using different orthogonal codeword Walsh covers.

    Abstract: An access terminal (AT) and a data-optimized cellular communication radio network (RN) negotiate a set of packet sizes for use on a reverse link between the AT and the RN. The negotiated set of packet sizes may differ from the default set of packet sizes defined in an existing standard, such as 1xEV-DO Revisions A and B. The packet sizes in the negotiated set may be tailored to provide a good fit with an application transmitting data on the reverse link, such as a voice encoder of a voice over Internet Protocol (VoIP) application. The AT and the RN communicate using the negotiated set of packet sizes. The packet sizes of the negotiated set may be mapped to the same reverse rate indicator (RRI) channel codewords as are defined in systems operating under the standard. Packing efficiency is thus increased, and higher capacity for delay-sensitive applications is achieved.
