Abstract: Methods, systems, and devices for multiplexing code block group (CBG) level and transport block (TB) level feedback are described. An example method includes receiving a set of TBs, generating a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and transmitting the bit sequence. Another example method includes transmitting a set of TBs, receiving a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and retransmitting at least one CBG for each TB in the first subset of TBs and the second subset of TBs based at least in part on the bit sequence.

Abstract: Methods, systems, and devices for multiplexing code block group (CBG) level and transport block (TB) level transmission and new data indications (NDIs) are described. An example method includes generating, for a transmission associated with a set of TBs, a bit sequence including TB-level indication of whether each TB in a first subset of TBs includes a retransmission, and CBG-level indication of whether a second subset of TBs includes a CBG-level retransmission, transmitting at least one grant comprising the bit sequence, and transmitting the transmission in accordance with the bit sequence. Another example method includes receiving a grant comprising a bit sequence including a TB-level indication of whether each TB in a first subset of TBs includes a retransmission, and CBG-level indication of whether a second subset of TBs includes a CBG-level retransmission, and monitoring for the set of TBs based at least in part on the bit sequence.

Abstract: Wireless communications systems and methods related to system information communications and decoding are provided. In one embodiment, a wireless communication device receives one or more known bits. The wireless communication device receives a first encoded information block. The wireless communication device decodes the first encoded information block to generate a first information block based on the one or more known bits. In one embodiment, a wireless communication device receives a first encoded information block including a first bit pattern. The wireless communication device receives a second encoded information block including a second bit pattern. The wireless communication device jointly decodes the first encoded information block and the second encoded information block based on an assumption that a difference between the first bit pattern and the second bit pattern is within a subset of a plurality of bit-change patterns.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a scheduling indicator on a first instance of a control channel. The wireless device may determine that a data transmission is scheduled for the wireless device based at least in part on the received scheduling indicator. The wireless device may identify a first frequency band associated with the data transmission and a second frequency band associated with a second instance of the control channel. The wireless device may identify a third frequency band to monitor based at least in part on the first and second frequency bands and a bandwidth capability of the wireless device. The third frequency band includes the first frequency band. The third frequency band comprises an associated bandwidth that is based at least in part on the bandwidth capability of the wireless device.

Abstract: A method of wireless communication includes determining a set of subframes with a reduced likelihood of being received as uplink transmissions of a first user equipment (UE). The method also includes scheduling uplink transmissions of the first UE by scheduling uplink control information (UCI) on subframes other than the determined set of subframes.

Abstract: Methods and apparatus for selecting samples for secondary synchronization signal (SSS) detection are described. Several alternatives are provided for efficient cell identifier detection. In a first alternative, multiple bursts of a signal received from a cell are sampled with non-uniform spacing between sampling intervals to determine a sequence for cell identification. In a second alternative, samples of a first and a second signal received from a stronger cell are cancelled, and a sequence for detecting a weaker cell is determined by reducing effects of the samples of a third signal received from the weaker cell which do not overlap with the primary synchronization signal (PSS) or SSS of the stronger cell. In a third alternative, a sequence for detecting a weaker cell is determined by reducing effects of any sampled bursts that correspond to a high transmission power portion of a signal from a stronger cell.

Abstract: When communications of a single radio access technology (RAT), or different radio access technologies in a proximate communication spectrum are operating at the same time, potential interference between devices may occur. To reduce the interference, the time division duplex (TDD) configuration of one or more conflicting device may be altered. For example, at the edge of a communication region, TDD configurations used by edge base stations to communicate with mobile devices may be set to reduce interference. As another example, communications of a first device may be altered so the first device schedules uplink communications when a second device also has uplink communications scheduled. Other configurations may also be implemented.

Abstract translation: 当单个无线电接入技术（RAT）或邻近通信频谱中的不同无线电接入技术的通信同时工作时，可能发生设备之间的潜在干扰。 为了减少干扰，可以改变一个或多个冲突设备的时分双工（TDD）配置。 例如，在通信区域的边缘，可以设置边缘基站用于与移动设备通信的TDD配置，以减少干扰。 作为另一示例，可以改变第一设备的通信，使得当第二设备还具有调度的上行链路通信时，第一设备调度上行链路通信。 也可以实现其他配置。

Abstract: In a wireless communication system, from available data resource elements (REs) in a subframe, REs are assigned to transmissions of a reference signal, thereby resulting in a plurality of remaining data REs. Furthermore, REs from the plurality of remaining data REs are assigned for data transmission to a wireless device in groups of a predetermined number of REs such that all assigned data REs within a group are within a predetermined number of symbols of each other in time domain and within a second predetermined number of subcarriers of each other in frequency domain, thereby resulting in at least one ungrouped RE.
