  • Patent number: 9844068
    Abstract: Techniques are disclosed that dynamically allocate communications resources in a wireless communications network, such as a wireless personal area network (WPAN). For instance, a wireless communications device may obtain a resource allocation. This resource allocation includes a time slot (e.g., a TDMA time slot) within a wireless communications medium. The device determines a first portion of the time slot in which it intends to transmit data. Also, the wireless communications device relinquishes a second portion of the time slot that occurs after the first portion of the time slot. Based on this relinquishment, a central controller device may reallocate the second portion of the time slot.

  • Patent number: 9774431
    Abstract: Systems and methodologies are described that facilitate providing high reuse for transmitting reference signals, such as positioning reference signals (PRS) and cell-specific reference signals (CRS), to improve hearability thereof for applications such as trilateration and/or the like. In particular, PRSs can be transmitted in designated or selected positioning subframes. Resource elements within the positioning subframe can be selected for transmitting the PRSs and can avoid conflict with designated control regions, resource elements used for transmitting cell-specific reference signals, and/or the like. Resource elements for transmitting PRSs can be selected according to a planned or pseudo-random reuse scheme. In addition, a transmit diversity scheme can be applied to the PRSs to minimize impact of introducing the PRSs to legacy devices. Moreover, potions of a subframe not designated for PRS transmission can be utilized for user plane data transmission.
