20090238124 | METHOD AND APPARATUS FOR COMBINED MEDIUM ACCESS CONTROL AND RADIO LINK CONTROL PROCESSING - A method and apparatus for combined medium access control (MAC) and radio link control (RLC) processing are disclosed. For uplink processing, a combined MAC/RLC (CMR) entity generates an SDU descriptor and allocates protocol data unit (PDU) descriptor resources. A protocol engine (PE) populates a PDU descriptor for each PDU carrying at least a portion of the SDU and generates a MAC PDU in a physical layer shared memory based on the SDU descriptor and the PDU descriptor. The MAC PDU is generated while moving RLC SDU data from the bulk memory to the physical layer shared memory. For downlink processing, received MAC PDUs are stored in the physical layer shared memory. The PE reads MAC and RLC headers in the MAC PDU and populates an SDU segment descriptor (SD) and corresponding PDU descriptors for each SDU segment. The CMR entity merges SDU SDs that comprise a same RLC SDU. | 09-24-2009 |
20090274248 | METHOD AND APPARATUS FOR CONTENTION-FREE INTERLEAVING USING A SINGLE MEMORY - A method and apparatus for contention free interleaving are disclosed. A single memory configured to use an address scheme wherein the most significant bits (MSBs) indicate which word in memory stores an interleaved piece of data. The least significant bits (LSBs) are used to calculate an index that identifies a specific soft-in/soft-out (SISO) decoder associated with a sub-word of the retrieved data. Using an interleaved address generator, the extrinsic data may be written into the memory in sequential order, but read out from the memory in interleaved order, effectively de-interleaving the data so it may be decoded. The generated interleaved address is used by SISO selector circuit which controls a multiplexer that routes the sub-word to its appropriate SISO decoder. The same address generator may be used to write interleaved extrinsic data from SISOs by reordering the sub-words, allowing the extrinsic data to be read in sequential order. | 11-05-2009 |
20100088529 | Data-Mover Controller With Plural Registers For Supporting Ciphering Operations - A data processing system ciphers and transfers data between a first memory unit and a second memory unit, such as, for example, between a share memory architecture (SMA) static random access memory (SRAM) and a double data rate (DDR) synchronous dynamic random access memory (SDRAM). The system includes a ciphering engine and a data-mover controller. The data-mover controller includes at least one register having a field that specifies whether or not the transferred data should be ciphered. If the field specifies that the transferred data should be ciphered, the field also specifies the type of ciphering that is to be performed, such as a third generation partnership project (3GPP) standardized confidentially cipher algorithm “f8” or integrity cipher algorithm “f9”. | 04-08-2010 |
20110158197 | METHOD AND APPARATUS FOR EFFICIENT OPERATION OF AN ENHANCED DEDICATED CHANNEL - A method for processing enhanced dedicated channel (E-DCH) data in a wireless transmit/receive unit (WTRU) includes sending two messages. A first message is sent from a physical layer to a medium access control (MAC) layer, and triggers MAC layer processing of E-DCH data. A second message is sent from the MAC layer to the physical layer, and enables the physical layer to compute control parameters for physical layer processing of the E-DCH data before the MAC layer processing of the E-DCH data is completed. | 06-30-2011 |
20110191532 | PROTOCOL ENGINE FOR PROCESSING DATA IN A WIRELESS TRANSMIT/RECEIVE UNIT - A protocol engine (PE) for processing data within a protocol stack in a wireless transmit/receive unit (WTRU) is disclosed. The protocol stack executes decision and control operations. The data processing and re-formatting which was performed in a conventional protocol stack is removed from the protocol stack and performed by the PE. The protocol stack issues a control word for processing data and the PE processes the data based on the control word. Preferably, the WTRU includes a shared memory and a second memory. The shared memory is used as a data block place holder to transfer the data amongst processing entities. For transmit processing, the PE retrieves source data from the second memory and processes the data while moving the data to the shared memory based on the control word. For receive processing, the PE retrieves received data from the shared memory and processes it while moving the data to the second memory. | 08-04-2011 |
20110271166 | PIPELINE ARCHITECTURE FOR MAXIMUM A POSTERIORI (MAP) DECODERS - The sliding window approach to pipeline maximum a posteriori (MAP) decoder architecture is modified to decrease processing time. Once the forward metrics have been calculated for he first sliding window of the decoder, the reverse metrics for each window are calculated while the forward metrics for the next window are calculated. As each new forward metric is calculated and stored into memory, the forward metric from the previous window is read from memory for use with reverse metric being calculated in calculating extrinsic value. Each forward metric for use in calculating an extrinsic value is written to the same memory location. The calculations can be reversed, reverse metrics being calculated first, followed by reverse metric calculations. Although this architecture was developed for a turbo decoder, all convolution codes can use the MAP algorithm of the present invention. | 11-03-2011 |

20150229970 | METHODS AND SYSTEMS FOR PACKET DIFFERENTIATION - Methods and systems are disclosed facilitate differentiated QoS service for packets within a single packet stream. For example, extended QCI values may be used to differentiate service of video packets associated with different priorities. A flexible representation of QoS requirements/parameters is disclosed where QoS may be defined as a hyperspace that is a function of base QoS parameters. A WTRU may explicitly specify and/or request desired QoS parameters. A WTRU may be configured to perform one or more of video packet separation into a plurality of video packet sub-streams, merging of the video packet sub-streams, and/or reordering of the packets included in the video packet sub-streams. Techniques may be utilized to exposing more information to a data transmission network regarding the type of video packets (and/or other packets) being transmitted. | 08-13-2015 |
