    Abstract: Techniques for transmitting data with persistent interference mitigation in a wireless communication system are described. A station (e.g., a base station or a terminal) may observe high interference and may send a request to reduce interference to interfering stations. The request may be valid for a time period covering multiple response periods. Each interfering station may grant or dismiss the request in each response period, may dismiss the request by transmitting at full power, and may grant the request by transmitting at lower than full power. The station may receive a response from each interfering station indicating grant or dismissal of the request by that interfering station in each response period. The station may estimate SINR based on the response received from each interfering station and may exchange data with another station based on the estimated SINR. Persistent interference mitigation may reduce signaling overhead and improve resource utilization and performance.

    Abstract: Methods, systems, and devices for wireless communication are described. In some examples, a wireless system may use a staggered uplink/downlink (UL/DL) format in which the symbol periods of the downlink are offset from the symbol periods of the uplink. Thus, if a user equipment (UE) receives a transmission in a first symbol period, it may decode the transmission and transmit a response in a staggered symbol period (e.g., in a UL control channel symbol period beginning one half of a symbol period after the first symbol period). A base station may then receive the response and, if it is a negative acknowledgement (NACK), retransmit during the third symbol period following the first symbol period. In another example, thin control channels may be used to reduce the round trip time between receiving a transmission and a retransmission.

    Abstract translation: 描述了用于无线通信的方法，系统和设备。 在一些示例中，无线系统可以使用交错的上行链路/下行链路（UL / DL）格式，其中下行链路的符号周期从上行链路的符号周期偏移。 因此，如果用户设备（UE）在第一符号周期中接收到传输，则它可以对传输进行解码并以交错的符号周期（例如，在UL控制信道符号周期内的符号周期后的一半开始发送响应 第一个符号期）。 然后，基站可以接收响应，并且如果它是否定确认（NACK），则在第一符号周期之后的第三符号周期期间重发。 在另一示例中，可以使用薄控制信道来减少接收传输和重传之间的往返时间。

    Abstract: Shared spectrum operation is disclosed for sharing spectrum among multiple wireless deployments. Coordination procedures between and among 2nd and 3rd Tier deployments include the use of beacons transmitted by the 2nd Tier for clearing access to spectrum occupied by 3rd Tier users and multiple 3rd Tier deployments sharing resources using a group-listen before talk (LBT) protocol, rather than a per-node LBT protocol. The 2nd Tier beacon signals are transmitted to alert 3rd Tier users of their presence, which, upon detection, will leave the particular spectrum within a predetermined time. For the shared LBT protocol, the 3rd Tier deployments share the channel with each other through an LBT with random backoff, in which the start time of clear channel assessment (CCA) procedure and the random backoff values are synchronized among nodes of the same deployment.

    Abstract: Coding techniques for a (e.g., OFDM) communication system capable of transmitting data on a number of “transmission channels” at different information bit rates based on the channels' achieved SNR. A base code is used in combination with common or variable puncturing to achieve different coding rates required by the transmission channels. The data (i.e., information bits) for a data transmission is encoded with the base code, and the coded bits for each channel (or group of channels with the similar transmission capabilities) are punctured to achieve the required coding rate. The coded bits may be interleaved (e.g., to combat fading and remove correlation between coded bits in each modulation symbol) prior to puncturing. The unpunctured coded bits are grouped into non-binary symbols and mapped to modulation symbols (e.g., using Gray mapping). The modulation symbol may be “pre-conditioned” and prior to transmission.
