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: Systems, methods, apparatuses, and computer-program products for performing dynamic bandwidth switching between control signals and data signals of differing bandwidths are disclosed. Frame formats are disclosed in which control signals are transmitted at different bandwidths than data signals. Receiver architectures for receiving the signaling formats are disclosed. A receiver can receive a relatively narrowband control signal while consuming a relatively low power and then dynamically adjust characteristics of various components to receive a data signal at a higher bandwidth while consuming a relatively higher power.

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: Techniques are described for wireless communication. A first method includes measuring, by a first device, a condition of a wireless channel; and generating at least one channel side information feedback message based on the measured condition of the wireless channel. The at least one channel side information feedback message provides information on a relationship of a set of parameters, including a data rate parameter, an error probability parameter, and at least one of a deadline parameter or a transmission link parameter. A second method includes measuring, by a first device, interference on a wireless channel; identifying an interfering device for the wireless channel based on the measurement; and generating a channel side information feedback message based on the measured interference on the wireless channel. The channel side information feedback message indicates the interfering device for the wireless channel and a correlation of interference from the interfering device with time or frequency.

Abstract: Methods, apparatus, and computer software are disclosed for communicating within a wireless communication network including a scheduling entity configured for full duplex communication, and user equipment (UE) configured for half duplex communication. In some examples, one or more UEs may be configured for limited (quasi-) full duplex communication. Some aspects relate to scheduling the UEs, including determining whether co-scheduling of the UEs to share a time-frequency resource is suitable based on one or more factors such as an inter-device path loss.

Abstract: Aspects of the present disclosure provide for the pairing of an inter-band carrier with a time division duplex (TDD) carrier. If the paired band is a frequency division duplex (FDD) band, then base stations and mobile devices may transmit and receive additional thin control channels on FDD carriers to enable full duplex operations. If the paired band is a TDD band, then a conjugate or inverse carrier may be used such that full duplex, or a close approximation thereto, is achieved. With the introduction of a paired channel and fast control channels, rapid uplink/downlink switching may be achieved for TDD carriers efficiently and effectively. Other aspects, embodiments, and features are also claimed and described.
