    Abstract: Methods and devices are disclosed for decoding multiple sparsely encoded data sequences in a wireless communications network. A received signal carrying multiple sparsely encoded data sequences is decoded by selecting a first plurality of the data sequences and performing multi-user decoding on the received signal to decode the first plurality of data sequences. Other data sequences are treated as noise. The plurality of data sequences is selected to meet a collision threshold for the multi-user decoding. Data sequences may be selected based on a collision contribution and signal quality metrics. A modified received signal is generated to remove signals associated with the multiple sparsely encoded data sequences which have been successfully decoded. The method may be performed for additional iterations to select a new plurality of data sequences, and perform the multi-user decoding on the modified received signal to decode additional data sequences, until a stopping condition is met.

    Abstract: Systems and methods for detecting potentially active user equipment (UE) in a network are provided. A set of potentially active UEs is detected using an iterative method. In a first iteration UE detection is performed using compressed sensing (CS) based on first pilot sequences to detect a first set of potentially active UEs. Channel estimation is then performed for the first set of potentially active UEs. In subsequent iterations, UE detection is performed using CS to detect another set, typically reduced in size, of potentially active UEs using results of the channel estimation from the previous iteration. Channel estimation is then again performed for the new set of potentially active UEs. After the last iteration, the set of potentially active UEs detected in the last iteration is output as the determined set of potentially active UEs along with channel estimates for the set of potentially active UEs determined in last iteration.

    Abstract: Methods, devices and systems for encoding and transmitting data in a wireless communications system and, in particular, for unscheduled data transmissions including low data rate transmissions. The method for transmitting data in a wireless network includes mapping data according to a predefined sequence pattern from a group of sequence patterns to provide a spreading sequence that includes multiple non-zero elements and that is enabled to partially collide in the wireless network with other spreading sequences that have been mapped according to other sequence patterns from the group; and transmitting the spreading sequence. Multiple sequences may be received by a network node and decoded using successive interference cancellation (SIC) techniques.

    Abstract: Control signaling in multiple access communication systems, including apparatus and methods, is disclosed. Multiple access to a wireless communication link is based on power modulation division. Modulation information, capacity information, resource scheduling information, and resource assignment information is determined by a base station. Information is transmitted to user equipment devices in a common control channel in accordance with the determined modulation information, capacity information and resource scheduling information. Information is also transmitted to supporting user equipment, which supports the power modulation division multiple access, in a user equipment-specific control channel in accordance with the determined resource assignment information.
