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.

Abstract: Nonzero elements of a signal vector, which may be a sparse signal vector, may be determined based on an observation vector representing a set of underdetermined observations using a compressed sensing optimization and a non-underdetermined estimation method such as iterative linear minimum mean-square error (“LMMSE”) estimation. Compressed sensing optimization may be used to obtain a subset of potentially nonzero elements of the signal vector, and LMMSE estimation may then be used to find the nonzero elements among the potentially nonzero elements. The identification of nonzero elements may then be used to recover the signal vector from the observation vector. This technique is useful for recovering compressed data such as a sparse frequency space representation of audio or video data from a measurement. The technique is also useful for identifying at a base station a relatively small number active devices in an overloaded communication network.

Abstract: Methods and systems for signal transmission in millimeter wave (mmW) range. A set of sequences is used to encode a data signal for one layer in a group of layers. Each sequence in the set of sequences has a length equal to the number of resources shared among the group of layers. At least a portion of the sequences have a low density of non-zero values, and the non-zero values are assigned to a subset of the shared resources. Each sequence assigns a non-zero value to at most one resource of the subset of shared resources, and all non-zero values assigned by all sequences have equal power amplitudes.

Abstract: In multi-domain modulation, also known as overlaid modulation, information is transmitted over more than one modulation domain. In such a transmission, different modulation domains are overlaid on top of each other. Signaling that is indicative of multiple modulation domains for overlaid modulation and is indicative of multiple modulation switching intervals is communicated in a wireless communication network, data modulated using the overlaid modulation is also communicated in the wireless communication network. The multiple modulation switching intervals include a respective modulation switching interval for each of the multiple modulation domains, and each respective modulation switching interval is different from other modulation switching intervals in the multiple modulation switching intervals.

Abstract: Some embodiments of the present disclosure provide control signaling mechanisms to support data transmission by a user equipment (UE) that is in the RRC_INACTIVE state and, more generally, in any inactive state. Beyond simply supporting data transmission by a user equipment that is in the RRC_INACTIVE state, aspects of the present application provide mechanisms for configuring the UE for preamble transmission or sounding reference signal (SRS) transmission and for toggling between such transmissions. Aspects of the present application relate to mechanisms for enabling Timing Advance estimation, which mechanisms are not burdened with high overhead and which allow the UE to remain in the RRC_INACTIVE state.

Abstract: Control signaling mechanisms are provided to support data transmissions to or from a user equipment (UE) in an inactive state. In some embodiments, a UE in an inactive state receives DCI including: a cyclic redundancy check (CRC) scrambled by a radio network temporary identifier (RNTI) that is specific to a group of UEs, the group of UEs including the UE; and a resource assignment for a data transmission to the UE. The data transmission is then received on a physical shared channel. In further embodiments, a UE in an inactive state receives DCI including: a CRC scrambled by a paging RNTI; and a resource assignment for a paging message to the UE. A data transmission is received by the UE in the paging message or in a further transmission that is scheduled by the paging message.
