An initial modulation and coding scheme (MCS) is selected for transmission of the packets based on channel conditions. The initial MCS is replaced by an alternative MCS having a lower efficiency than the initial MCS in response to a determination that the alternative MCS would require the same number of resource blocks to transmit a packet having the particular packet length as the initial MCS. One or more resource blocks are allocated for transmission of the one or more packets having the particular packet length using the alternative MCS. Indications of the allocated one or more resource blocks and the alternative MCS are transmitted to the UE.

    Abstract: Embodiments are disclosed for fast data fetching and rendering. In some embodiments, in response to receiving a page display request, a system constructs a static, possibly nested query for retrieving all the data to be rendered for the page and stores the query result in a data store. For a future page display request, the system similarly constructs a query and determines whether the query can be resolved from the data store. If not, the system constructs a “diff query” to fetch only the missing data. In some embodiments, in response to a subsequent page update request, the system retrieves from the server all the data likely to be viewed or updated and renders the data changes corresponding to the requested update. The system then submits the data changes to the server and undoes the rendering of the data changes when the server fails to process the data changes.

  • Patent number: 10216574
    Abstract: 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.

  • Patent number: 10200162
    Abstract: 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.

  • Patent number: 10194429
    Abstract: In a mobile station that performs communication with a base station device via a plurality of cells, the plurality of cells are grouped into a first group constituted by cells having an uplink transmission timing that is the same as that of one primary cell and a second group constituted by one or more cells having an uplink transmission timing that is different from that of the primary cell. The uplink transmission timings are each managed using a corresponding transmission timing timer for each of the groups. In a case where a transmission timing timer for the first group has expired, the mobile station stops all uplink transmissions in the plurality of cells. In a case where a transmission timing timer for the second group has expired, the mobile station stops uplink transmissions in the cells constituting the second group for which the transmission timing timer has expired.

  • Patent number: 10159092
    Abstract: Methods and apparatus are provided contention based uplink data transmission. In one novel aspect, the contention-based uplink data channel is used to transmit the data directly to the network. In one embodiment, the UE selects an UL data channel from a set of preconfigured uplink contention based data channels and sends the UL data transmission on the selected UL data channel. In one embodiment, the contention based UL data has a narrow bandwidth with a long CP such that the TA is not needed from the base station. In another embodiment, a small signaling payload is included in the CB UL data transmission if the size of the data contents cannot be fit in the UL data channel. In one embodiment, the signaling payload is the BSR. The UE, subsequently, receives an UL grant and sends the remaining data contents using the allocated data channel in the UL grant.

  • Patent number: 10154188
    Abstract: A master camera device and a plurality of slave camera devices are directly connected through a network, and form one network segment. The master camera device performs multicast communication with each slave camera device, and acquires information representing a transmission condition from each slave camera device. In a case where a worsening transmission condition relative to a predetermined threshold is detected from a transmission condition of each slave camera device and a transmission condition of the master camera device, the master camera device performs multicast communication with each slave camera device, and controls an encoding level representing a degree of encoding process, sequentially from an encoder having a lower priority, including the encoder of the master camera device, to improve the transmission condition. Thus, by an efficient communication, the transmission condition is improved from an initial stage having an unstable transmission condition, to obtain a preferable real-time image.

  • Patent number: 10135517
    Abstract: A method for preventing a first network node from missing a transmission from a second network node. The method includes, when a ten millisecond periodicity is used for Multicast/Broadcast Single Frequency Network (MBSFN) subframes, setting a time between an uplink grant from the second network node to the first network node and an acknowledgement/negative-acknowledgement message (ACK/NACK) from the second network node to the first network node equal to ten milliseconds. The method further includes, when a forty millisecond periodicity is used for MBSFN subframes, the second network node sending the first network node an asynchronous grant for an uplink retransmission when a data packet is missed, and when the first network node receives the grant for the uplink retransmission, the first network node retransmitting the missed data packet.
