Patent number: 10216574Abstract: A data storage system configured to adaptively code data is disclosed. In one embodiment, a data storage system controller determines a common memory page size, such as an E-page size, for a non-volatile memory array. Based on the common memory page size, the controller selects a low-density parity-check (LDPC) code word length from a plurality of pre-defined LDPC code word lengths. The controller determines LDPC coding parameters for coding data written to or read from the memory array based on the selected LDPC code word length. By using the plurality of pre-defined LDPC code word lengths, the data storage system can support multiple non-volatile memory page formats, including memory page formats in which the common memory page size does not equal any LDPC code word length of the plurality of pre-defined LDPC code word lengths. Flexibility and efficiency of data coding can thereby be achieved.Type: GrantFiled: December 15, 2014Date of Patent: February 26, 2019Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.Inventor: Guangming Lu

Patent number: 10205564Abstract: A method and apparatus for transmitting and receiving a packet via high speed downlink packet access (HSDPA) are disclosed. At least one HSDPA medium access control (MAC-hs) service data unit (SDU) is segmented into a plurality of segments. MAC-hs protocol data units (PDUs) are generated from the segments wherein each MAC-hs PDU includes at least one segment. Each MAC-hs PDU may include one segment from a single MAC-hs SDU. The size of the segments may match to the size of the MAC-hs PDUs minus the size of the header of the MAC-hs PDU. The sizes of the segments may be determined based on the number of segments to which the MAC-hs SDU is segmented. Alternatively, each MAC-hs PDU may include a combination of segments from a plurality of MAC-hs SDUs or a combination of at least one segment from one MAC-hs SDU and at least one entire MAC-hs SDU.Type: GrantFiled: May 6, 2011Date of Patent: February 12, 2019Assignee: InterDigital Technology CorporationInventors: Christopher R.

Patent number: 10200162Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems operating in unlicensed or shared radio frequency spectrum band may use different modes to manage hybrid automatic repeat request (HARQ) feedback. HARQ feedback may be transmitted autonomously or, in some cases, HARQ feedback may be solicited from a user equipment (UE) for one or several HARQ processes. Solicited feedback may be referred to as polled feedback and autonomous feedback may be referred to as unpolled feedback. Polled and unpolled feedback may be transmitted using different physical channels, and may be grant-based or triggered without an express grant. Buffers for polled and unpolled feedback may be separately maintained and managed. In a multicarrier configuration, uplink control information (UCI) for one or more carriers may be transmitted on a subset of configured uplink carriers. A number of carriers used for UCI may depend on operating conditions of a UE.Type: GrantFiled: May 24, 2017Date of Patent: February 5, 2019Assignee: QUALCOMM IncorporatedInventors: Arumugam Chendamarai Kannan, Chirag Patel, Tao Luo
