摘要： A method and system for demodulating high-order Quadrature Amplitude Modulation (QAM) signals is disclosed. In one embodiment, the system includes a cyclic prefix (CP) removal unit for removing a CP from a received signal to provide a first intermediate signal, wherein the first intermediate signal comprises a plurality of bits; a fast Fourier transform (FFT) unit configured to convert the first intermediate signal into a frequency domain; a soft de-mapper configured to derive a plurality of soft bits based on log-likelihood estimates of the plurality of bits, wherein the soft de-mapper derives each soft bit by using a single linear function to approximate each soft bit; and a decoder configured to decode a signal derived from the soft de-mapper into information.

摘要： A cellular telecommunications system and method of scheduling a group of user equipments is provided. The system includes a macro cell with a macro base station and multiple associated low power nodes (LPN's). The macro base station and the LPN's share the same cell ID. The system and method provide for scheduling a group of UE's by grouping a plurality of the UE's together, assigning a group identifier to the group, notifying the group and encoding a control channel with the group identifier. A single control channel is delivered to each UE in the group of UE's. The UE's of the group of UE's may be processed by different LPN's. The transmitted control channel may be included in a DCI (downlink control information) and delivers uplink scheduling grants to the UE's. Based on the transmitted control channel, the UE's are scheduled for uplink transmission.

摘要： A method, system and non transitory, tangible computer readable storage medium provides for controlling the BLER (block error rate) in a digital communication system. The outer loop control of the system discounts responses sent by a receiver to data transmission from a transmitter that were sent during a receiver outage event. Either the NACKs or both the ACKs and NACKs sent by the receiver during receiver outage are discounted by the outer loop control which adapts subsequent transmissions by either directly adjusting transmission parameters or by adjusting the selection of transmission parameters. The adapting may be based on individual NACKs and ACKs or after establishing a BLER.

摘要： A method of determining an uplink subframe type by user equipment includes the following steps: receiving an uplink grant from a base station, wherein the uplink grant is associated with a first flexible subframe within a first radio frame; determining a first index of the first flexible subframe within the first radio frame; identifying a second flexible subframe within a second radio frame; determining a second index of the second flexible subframe within the second radio frame; and determining a type for the second flexible subframe based at least on the first index of the first flexible subframe and the second index of the second flexible subframe. In some embodiments, the first and second radio frames are the same one. In other embodiments, the first and second radio frames are two different ones that fall within the same downlink/uplink configuration period.

摘要： A device and method and system for dynamically processing a random access response (RAR) signal to perform wireless communications is disclose. In some embodiments, the device is configured to receive one or multiple random access response (RAR) signals, wherein when the processor receives multiple RAR signals, it selects a RAR signal and responses to the selected RAR signal based on a content of the one or multiple RAR signals and proceeds with subsequent wireless communication using information contained in the selected RAR signal.

摘要： A new approach to generating a probing signal by a cell in a heterogeneous network (HetNet) deployment is proposed. A small cell in the HetNet may be switched off by a base station when the small cell is not needed. The small cell is configured to alternate between an off-state and on-state. The small cell maintains the on-state for a predetermined probing period and maintains the off-state for a predetermined off period. The small cell may switch between the on-state and the off-state periodically. The small cell may be activated during a predetermined off period to transmit data to a user device.

摘要： An auxiliary cell identity (ACI) is proposed besides the conventional physical cell identity carried on the synchronization channels. The ACI is designed and configured to be transmitted in one or more primary regions and one or more secondary regions and transmitted by a base station/cell to a plurality of user equipment (UEs) located within coverage of the cell in one or more transmissions. Each of the UEs is configured to detects the transmitted ACI and identifies the cell based on the detected ACI.
