Abstract: System and method embodiments are provided for non-cellular wireless access. In an embodiment, a method for non-cell grid based radio access in a radio access network includes determining, by a controller, a group of transmit points (TPs) to assign to a logical entity; assigning, by the controller, a logical entity identifier (ID) to the logical entity, wherein the logical entity ID identifies the logical entity through which a user equipment (UE) communicates with the radio access network; and causing, by the controller, at least one of the TPs in the logical entity to send signals to the UE.

Abstract: Embodiments are provided for an asynchronous processor with pipelined arithmetic and logic unit. The asynchronous processor includes a non-transitory memory for storing instructions and a plurality of instruction execution units (XUs) arranged in a ring architecture for passing tokens. Each one of the XUs comprises a logic circuit configured to fetch a first instruction from the non-transitory memory, and execute the first instruction. The logic circuit is also configured to fetch a second instruction from the non-transitory memory, and execute the second instruction, regardless whether the one of the XUs holds a token for writing the first instruction. The logic circuit is further configured to write the first instruction to the non-transitory memory after fetching the second instruction.

Abstract: Embodiments are provided for an asynchronous processor with heterogeneous processors. In an embodiment, the apparatus for an asynchronous processor comprises a memory configured to cache instructions, and a first unit (XU) configured to processing a first instruction of the instructions. The apparatus also comprises a second XU having less restricted access than the first XU to a resource of the asynchronous processor and configured to process a second instruction of the instructions. The second instruction requires access to the resource. The apparatus further comprises a feedback engine configured to decode the first instruction and the second instruction, and issue the first instruction to the first XU, and a scheduler configured to send the second instruction to the second XU.

Abstract: A number K of N sub-channels that are defined by a code and that have associated reliabilities for input bits at N input bit positions, are to be selected to carry bits that are to be encoded. A localization area that includes multiple sub-channels and is located below fewer than K of the N sub-channels in a partial order of the N sub-channels is determined based on one or more coding parameters. The fewer than K sub-channels of the N sub-channels above the localization area in the partial order are selected, and a number of sub-channels from those in the localization area are also selected. The selected fewer than K sub-channels and the number of sub-channels selected from those in the localization area together include K sub-channels to carry the bits that are to be encoded.

Abstract: Embodiment techniques map parity bits to sub-channels based on their row weights. The row weight for a sub-channel may be viewed as the number of “ones” in the corresponding row of the Kronecker matrix or as a power of 2 with the exponent (i.e. the hamming weight) being the number of “ones” in the binary representation of the sub-channel index (further described below). In one embodiment, candidate sub-channels that have certain row weight values are reserved for parity bit(s). Thereafter, K information bits may be mapped to the K most reliable remaining sub-channels, and a number of frozen bits (e.g. N−K) may be mapped to the least reliable remaining sub-channels. Parity bits may then mapped to the candidate sub-channels, and parity bit values are determined based on a function of the information bits.

Abstract: A clock-less asynchronous processing circuit or system utilizes a self-clocked generator to adjust the processing delay (latency) needed/allowed to the processing cycle in the circuit/system. The timing of the self-clocked generator is dynamically adjustable depending on various parameters. These parameters may include processing instruction, opcode information, type of processing to be performed by the circuit/system, or overall desired processing performance. The latency may also be adjusted to change processing performance, including power consumption, speed etc.
