Abstract: The disclosure relates in some aspects to techniques for use in systems where a plurality of devices with different priority levels share a common set of resources for communication (e.g., downlink transmissions). Certain aspects provide a new indication channel and a procedure to signal scheduling information (e.g., priority information). Such information may serve as an indicator for possible new grants. Such information may additionally serve as an indicator for higher-priority scheduling conflicts or include explicit commands that result from conflicts (e.g., conflicts relating to puncturing of resources allocated for transmissions to lower priority devices).

Abstract: Aspects of the present disclosure provide a self-contained subframe structure for time division duplex (TDD) carriers. Information transmitted on a TDD carrier may be grouped into subframes, and each subframe can provide communications in both directions (e.g., uplink and downlink) to enable such communications without needing further information in another subframe. In one aspect of the disclosure, a single subframe may include scheduling information, data transmission corresponding to the scheduling information, and acknowledgment packets corresponding to the data transmission. Furthermore, the subframe may additionally include a header and/or a trailer to provide certain bi-directional communications functions.

Abstract: Bursty interference or puncturing may be identified, either by a user equipment (UE) or by a base station. In response, a protection scheme may be applied to protect communications from the bursty interference or puncturing. The protection scheme may include using both time and frequency interleaving of code blocks in the communications. The protection scheme may also include modifying the modulation and coding scheme (MCS), coding rate, precoding matrix index (PMI), or rank indicator (RI) used in the communications. The protection scheme may also include using a universal low-density parity check (LDPC) code in the transmission of the communications.

Abstract: Techniques for determining power relaxation values are disclosed. The power relaxation values may be determined according to an ending resource block (RB) and a number of RBs in a contiguous allocation. In one aspect, the power relaxation values are arranged into regions based, at least in part, on transmission channel bandwidths and the distance from a protected adjacent channel. A user equipment (UE) can determine a power relaxation value for its current allocation using the ending RB index and contiguous RB length and can adjust its transmission power accordingly. Evolved NodeBs may estimate the power relaxation that a particular UE has selected in order to more accurately determine the transmit power available to the UE. Using the more accurate estimate of transmit power, the eNB may schedule the UE for uplink transmissions accordingly.

Abstract: Some aspects of the present disclosure provide for methods, apparatus, and computer software for low-power synchronization of wireless communication devices. In one example, an asynchronous code division multiple access (CDMA) channel may be utilized for uplink communication. By utilizing asynchronous CDMA on the uplink, synchronization requirements are relaxed relative to other forms of communication. Accordingly, a synchronization period after coming out of a sleep state can be short, reducing power consumption during re-synchronization. In another example, a low-power companion receiver, rather than the full-power WWAN receiver, may be utilized to acquire a sync signal while the device is in its sleep state. Once synchronism is achieved via the low-power companion receiver, the full-power radio may power up and perform communication with the network. By shifting the synchronization from the full-power radio to the low-power companion radio, power consumption during re-synchronization can be achieved.

Abstract translation: 本公开的一些方面提供了用于无线通信设备的低功率同步的方法，装置和计算机软件。 在一个示例中，异步码分多址（CDMA）信道可用于上行链路通信。 通过在上行链路上利用异步CDMA，相对于其他形式的通信，同步要求是放宽的。 因此，从睡眠状态出来之后的同步时间可能很短，从而减少了重新同步期间的功耗。 在另一示例中，低功率配套接收机而不是全功率WWAN接收机可用于在设备处于其睡眠状态时获取同步信号。 一旦通过低功率配套接收器实现同步，全功率无线电可以加电并与网络进行通信。 通过将同步从全功率无线电转移到低功率配套无线电，可以实现重新同步期间的功耗。
