20210336697 | Integrated Track-and-Receive System for Free-Space Optical Communications - A monostatic, beaconless fiber transceiver for free-space optical links infers fine tracking information using receiver optoelectronics and an injected pointing dither (nutation). A MEMS steering mirror fine-points the beams and injects the nutation. While this may disturb fiber coupling and transmit beam pointing, link loss becomes negligible for sufficient SNR. The SNR for links without point-ahead correction is about 35 dB to keep dither loss below 0.1 dB and RMS spatial tracking noise below a tenth of the beam divergence. Since the pointing and tracking bandwidth is much smaller than the receiver communication bandwidth, this SNR is achievable with appropriate filtering. For point-ahead correction, a single-mode fiber transceiver can reach up to about 1 beamwidth of correction, while a few-mode fiber transceiver can reach up to about 1.75 beamwidths due to improved coupling sensitivity at higher point-ahead offsets. Using a double-clad fiber with a secondary detector further reduces the incurred coupling loss. | 2021-10-28 |

Said method comprises: a terminal device determining a target parameter, the target parameter being the index number of a configured grant or time Domain Offset configured in a configured grant or HARQ process information configured in a configured grant; and determining, according to the target parameter, the HARQ process ID of each HARQ process corresponding to the configured grant. In the present application, one of the target parameters is introduced in the process of determining the HARQ process ID of an HARQ process, so that the HARQ process IDs of HARQ processes corresponding to a plurality of configured grants have different values, thereby solving the problem of an HARQ process ID conflict when no feedback is received in the HARQ processes or before the time out of a configured grant timer. | 2021-10-28 |
20210336728 | ADVANCED FEEDBACK IN SIDELINK - A wireless communication system includes one or more base stations, and a plurality of UEs for a sidelink communication using sidelink resources. The UEs includes a transmitting UE and a receiving UE using a subset of the sidelink resources of the wireless communication system. The receiving UE sends over the sidelink a sidelink feedback to the transmitting UE. The sidelink feedback indicates for a data transmission a successful or non-successful reception at the receiving UE. The transmitting UE reports the sidelink feedback to a base station. The base station provides to the transmitting UE, responsive to the sidelink feedback, sidelink resources for a possible retransmission of a data packet over the sidelink to the receiving UE. The reporting of the sidelink feedback to the base station by the transmitting UE is activated or deactivated responsive to one or more conditions. | 2021-10-28 |
20210336729 | Memory Conservation In Delta-Compressed Message Transmission And Recovery - Instructions stored on a computer-readable medium include, in response to receiving a new message for transmission, generating a candidate message by attempting recovery of a previous message from the new message and recovery bits of the previous message. The instructions include, in response to an indicator indicating that the attempted recovery was successful, computing a delta between the new message and the candidate message and generating a delivery message based on the computed delta. The instructions include, in response to the indicator indicating that the attempted recovery was unsuccessful, generating the delivery message based on the new message exclusive of the computed delta. The instructions include calculating new recovery bits from the new message. The instructions include storing the new recovery bits as the recovery bits of the previous message. The instructions include transmitting the delivery message to a destination over a communications channel. | 2021-10-28 |
20210336730 | Feedback Information Sending or Receiving Methods, Devices and System - The embodiments of the application provide feedback information sending or receiving methods, devices and a system, and relate to the field of communication. The method includes that: a first bit length is determined, the first bit length being a number of bits for representing Transport Block (TB)-level feedback response information; a second bit length is determined, the second bit length being a number of bits for representing target TB indication information; feedback information is generated according to the first bit length and the second bit length, the feedback information including the TB-level feedback response information, the target TB indication information and code block group-level feedback response information; and the feedback information is sent. | 2021-10-28 |
