  • Patent number: 10305627
    Abstract: A wireless communication system is presented for adaptive uplink (UL) link adaptation (LA). The adaptive UL LA can include multiple outer loops, for which multiple block error rate (BLER) filtering is performed. Each of the multiple BLER filtering can be performed on groups or sub-groups of subframes, in which each group has the same or similar coding characteristics. For example, one group in TD-LTE could be subframes with sounding reference signal (SRS) and another group could be subframes without SRS. Each of the multiple BLER filtering can use the same or different BLER algorithm, BLER target and/or BLER parameters.

  • Patent number: 10299264
    Abstract: Where first and second reference signals for a first and second communication system, respectively, are transmitted, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame based on CSI-RS allocation information, measures channel quality by using this CSI-RS, and transmits and reports feedback information.

  • Patent number: 10271309
    Abstract: Systems and methods are disclosed for transmission and reception of an uplink grant during a gap created in radio resources assigned by a previous multiple Transmit Time Interval (multi-TTI) uplink grant in a system operating according to a Time Division Duplexing (TDD) scheme. In one embodiment, a method of operation of a radio network node in a cellular communications network is provided. The method includes transmitting a first uplink grant that assigns radio resources for a multi-TTI uplink transmission, and transmitting a second uplink grant during a gap in the radio resources assigned by the first uplink grant. In one embodiment, by utilizing the gap to transmit the second uplink grant, uplink radio resources assigned for uplink transmission can be maximized, which is particularly beneficial in high uplink traffic conditions.

  • Patent number: 10200982
    Abstract: Systems and methods to encode and/or decode structured super-position coding to enhance control channel capacity are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). A first UE and a second UE may be coupled to the eNB. Basic PDCCH may be sent to the second UE, and extra PDCCH may be sent to the first UE on the same time-frequency resource. The second UE may be able to decode the basic PDCCH as it normally does. The first UE may be able to decode the basic PDCCH for the second UE, cancel the basic PDCCH from the signal, and decode the extra PDCCH. The extra PDCCH may be restricted to certain positions relative to the basic PDCCH to simplify searching by the first UE.

  • Patent number: 10187857
    Abstract: A station that performs a method to coordinate transmissions of scheduling requests (SR) with OnDurations of a connected discontinuous reception (C-DRX) cycle. The station receives a packet at a packet arrival time relative to a schedule indicating the SR opportunities and onDurations, the SR opportunities occurring at a first interval, the onDurations occurring at a second interval, the first interval being less than the second interval. The station determines an SR opportunity subsequent to the packet arrival time that precedes an entirety of a subsequent onDuration, such that a transmission duration to transmit the SR and the packet maximally overlaps with the selected onDuration. A sleep mode of the processor of the station is used until a time associated with the selected SR opportunity. An active mode of the processor is used to transmit the SR and receive control channel information during the onDuration.

  • Patent number: 10187801
    Abstract: One embodiment provides a system that facilitates a large-scale mobile ad hoc network to adapt to specific needs of wireless nodes in a mobile wireless network. During operation, a controller node collects state information associated with one or more wireless nodes. The controller node allocates one or more network elements based on the collected state information and a predetermined utility-based technique. Responsive to the allocation of the one or more network elements, the controller node reconfigures a logical topology of the mobile wireless network by using software-defined mobile ad hoc network nodes, thereby facilitating a large-scale mobile ad hoc network to adapt to specific application needs of wireless nodes.

  • Patent number: 10178053
    Abstract: An improved method of hierarchical output queueing of packets for a network scheduler of a network gateway that determines delays needed to conform to applicable rate shaping, and enqueues the packets based on the delay. Queues are associated with different classes of service (CoS), and within each class, each queue has a different scheduled time upon which it becomes available for dequeuing. A single set of CoS queues can support a large number of devices, improving the efficiency of software-based queuing by reducing the number of queues and simplifying queue polling.

  • Patent number: 10164729
    Abstract: A system including a direct current tone, guard tone, data tone allocation, mapping, and inverse Fourier transform (IFT) modules. The direct current tone module determines a number of direct current tones based on whether a network device is operating in a single user or multi-user mode. The guard tone module determines a number of guard tones based on whether the network device is operating in the single user or multi-user mode. The data tone allocation module determines a number of data tones based on the number of direct current and guard tones. The mapping module receives data and based on the number of data tones, maps the data to the data tones. The IFT module performs a frequency to time domain conversion of an output of the mapping module to generate orthogonal frequency division multiplexing (OFDM) symbols during the single user mode and OFDM access symbols during the multi-user mode.

  • Patent number: 10135595
    Abstract: A system and method to instruct a User Equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.
