Abstract: A method (300, 500) and apparatus (200) that transmits and/or receives positioning reference signals in a wireless communication network using a mixture of cyclic prefix types. The method may include configuring (320) subframes in the wireless communication network as multicast broadcast single frequency network subframes. The method may include configuring (330) subframes in the wireless communication network as positioning subframes including positioning reference signals. The method may include determining (340) whether all of the positioning subframes are multicast broadcast single frequency network subframes. The method may include generating (350) extended cyclic prefix positioning reference signals for all of the positioning subframes if all of the positioning subframes are multicast broadcast single frequency network subframes.

Abstract: A method for predicting performance of a radio link in a wireless communication terminal including hypothesizing a second codeword including information associated with a hypothesized first codeword, obtaining channel state information from a received signal, and estimating a decoder error rate of the first codeword under a condition that the second codeword may not be decoded correctly, wherein the decoder error rate is estimated using the channel state information.

Abstract: A method, telecommunication apparatus, and electronic device for detecting a status of a radio link are disclosed. A transceiver 302 may maintain a radio link with a network base station 104. A processor 304 may map channel state information to a synchronization status associated with the radio link based on the received signal and determine the synchronization status via a block error rate estimate in the radio link based on the channel state information.

Abstract: Apparatuses, systems, and methods are described for power allocation in a superposition multiple access communication system capable of using non-uniform joint constellations or super-constellations. In one method, the conditional probability of a correctly-received symbol and a normalized weighting coefficient is calculated for each receiver and then the sum of weighted efficiencies is calculated. The optimal power allocation is determined for each receiver by maximizing the sum of weighted spectral efficiencies.

Abstract: A method, a mobile system, and a user device for determining a delay spread are disclosed. A memory 306 may store a compound test value based on a multiburst history. The multiburst history may be a set of power delay profile decisions. A processor 304 may create a short power delay profile channel estimate and a long power delay profile channel estimate. The processor 304 may select a chosen power delay profile channel estimate based on the compound test value.

Abstract: A method (700, 800) and apparatus (500, 600) for distinguishing cells with the same physical cell identifier is disclosed. The method can include receiving (820) a handover request message including target cell timing offset information at a potential target cell base station, where the potential target cell base station can have a physical cell identifier. The method can include comparing (830) the received target cell timing offset information with stored timing offset information at the potential target cell base station. The method can include sending (840) a handover request accept message if the received target cell timing offset information is substantially equal to the stored timing offset information. The method can also include receiving (720), at a wireless terminal, a target cell physical cell identifier and determining (730) a target cell timing offset of a radio frame of the target cell with respect to reference timing of a serving cell. The method can include sending (740) a measurement report including the target cell physical cell identifier and the target cell timing offset.
