摘要： A method for optimized access of a physical random access channel, PRACH, includes paging a plurality of mapped zones associated with a base station. Each of the mapped zones has a plurality of endpoints. The method further includes determining a subset of disconnected endpoints in a given mapped zone where the disconnected endpoints are disconnected from a wireless network. The method also includes estimating a PRACH load based on the subset of disconnected endpoints. Additionally, based on whether the estimated PRACH load is a pre-determined factor larger than an original PRACH allocation, the method includes increasing the PRACH allocation to accommodate reconnection of the subset of disconnected endpoints in the given mapped zone.

摘要： A method of compensating for transmitting to multiple devices during device-to- device (D2D) communications may include determining that a receiving wireless device of a device-to-device (D2D) pair may experience a timing conflict.

The method may also include adjusting the D2D communication to compensate for the timing conflict.
