  • Patent number: 9143946
    Abstract: Systems and methodologies are described that facilitate assigning carriers to access points based on power class. Devices can accordingly evaluate cells provided by the access points to select a cell with an optimal SNR or path loss for communication regardless of power class, since lower powered cells will not be interfered by higher powered cells communicating over different carriers. Cross-carrier operation is also provided where access points can transmit downlink signals according to carrier assignment information while receiving uplink signals over other carriers. Thus, once an optimal cell is determined, downlink control data can be received over the assigned carrier to ensure receipt without interference, but uplink transmissions can occur over multiple carriers to facilitate increased throughput using one or more reuse schemes.

  • Patent number: 9112692
    Abstract: Techniques for acknowledging data transmissions in a multi-carrier wireless communication network are disclosed. In some aspects, a user equipment (UE) receives a data transmission on at least one component carrier (CC) in a plurality of configured CCs. The UE determines acknowledgement/negative acknowledgement (ACK/NACK) information for the data transmission and determines an uplink channel for sending the ACK/NACK information. When the ACK/NACK information is sent on a physical uplink control channel (PUCCH), the UE may perform power control based on which CCs in the plurality of configured CCs data is received. When the ACK/NACK information is sent on a physical uplink shared channel (PUSCH), the UE may determine a number of resource elements based on its CC configuration.

  • Patent number: 9084119
    Abstract: Systems and methodologies are described that facilitate employing fractional frequency reuse within carriers in a multicarrier heterogeneous wireless communication environment. Each carrier can be divided into a plurality of frequency reuse sets. Moreover, each of the frequency reuse sets from each carrier can be categorized as being for one of unrestricted reuse or restricted reuse. Further, a downlink transmission can be scheduled upon resources of at least a first subset of frequency reuse sets from a first carrier bandwidth and a second subset of frequency reuse sets from a second carrier bandwidth. For example, the resources can be scheduled based upon a power class of a base station, categorizations of the frequency reuse set (e.g., unrestricted reuse versus restricted reuse, . . . ), and/or received feedback related to downlink channel conditions.

  • Patent number: 9084209
    Abstract: Methods, systems, devices, and computer program products are disclosed which facilitate the transmission and reception of power headroom reports for component carriers in a multi carrier wireless communication system. A mobile device may determine available power headroom in a multicarrier configuration through a calculation of a maximum transmit power associated with a first component carrier (CC) in a subset of the CCs. The calculation can account for increases in transmit power of other component carriers in the subset by proportionally increasing transmit powers for each of the subset of CCs. A power headroom may be identified for one or more of the CCs based on a result of the calculation, and a power headroom report (PHR) may be generated that includes the power headroom available for the first CC.

  • Patent number: 9042277
    Abstract: Techniques for transmitting control information to support communication on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured for operation on multiple CCs. These CCs may be associated with control messages having different definitions. For example, a control message for a CC configured for frequency division duplex (FDD) may have a different definition than a control message for a CC configured for time division duplex (TDD). A base station may send first control information for a first CC based on a definition of a control message for a second CC, instead of a definition of a control message for the first CC. The control message for the second CC may be selected for use to send the first control information based on various designs.

  • Patent number: 9036564
    Abstract: Techniques for dynamically assigning acknowledgement (ACK) resource to a user equipment (UE) are described. For dynamic scheduling, a scheduling message may be used to send scheduling information for a single transmission of data. For semi-persistent scheduling, a scheduling message may be used to send a semi-persistent assignment for multiple transmissions of data. In an aspect, at least one field of a scheduling message, which is normally used to carry scheduling information for dynamic scheduling, may be re-used to carry an ACK resource assignment for semi-persistent scheduling. In one design, a UE may receive a scheduling message carrying a semi-persistent assignment and may obtain an assignment of ACK resource from the at least one field of the scheduling message. The UE may receive a transmission of data sent in accordance with the semi-persistent assignment, determine ACK information for the transmission of data, and send the ACK information with the ACK resource.
