Abstract:
Uplink scheduling for license assisted access (LAA) mode systems is discussed in which a base station transmits a conditional grant to served user equipments (UEs) that include a transmission configuration for uplink transmissions. The transmission configuration includes the parameters necessary for the UE to perform transmissions. Before the beginning of a uplink transmission opportunity, a base station transmits an uplink activation grant over a contention-based shared carrier to the served UEs. The uplink activation grant indicates the transmission opportunity to the UEs and may identify a subset of UEs out of the served UEs that are available for transmission. The base station first secures the channel before transmitting the uplink activation grant. Upon receipt of the uplink activation grant, the UEs determine whether they will perform uplink transmissions and, if so, transmit the uplink data according to the transmission configuration.
Abstract:
In the present disclosure, CSI and/or a plurality of ACK/NACKs related to a group of DL data transmissions may be buffered at the UE as a GACK until a DCI trigger is received from the eNB. When the DCI trigger is received, the UE may transmit the CSI and/or GACK. In this way, HARQ feedback and/or CSI may be reliably communicated even if a CCA does not clear and/or UL subframes are unavailable. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In an aspect, the apparatus may be a UE. The apparatus monitors one or more subframes for a DCI trigger. In a further aspect, the apparatus receives the DCI trigger in a subframe. In another aspect, the apparatus transmits UCI using a subsequent subframe.
Abstract:
A method for allocating network resources to user equipments (UEs) includes configuring a first group of component carriers with resource allocations indicated by a joint downlink control information (DCI) message, configuring a second group of component carriers with resource allocations for each component carrier indicated by a dedicated DCI message, generating the joint DCI message indicating first resource allocations for a first subset of the first group of component carriers, generating a plurality of dedicated DCI messages, wherein each dedicated DCI message indicates a second resource allocation for a component carrier in a second subset of the second group of component carriers, mapping each one of the joint DCI message and the plurality of dedicated DCI messages to a control channel, and sending the control channels to the UE.

Abstract:
Various aspects described herein relate to communicating in a wireless network. An uplink resource grant can be received from a network entity for communicating in the wireless network. A transmission time interval (TTI) for an uplink transmission within a subframe based on the uplink resource grant can be determined, wherein the TTI comprises one or more symbols which are a subset of a plurality of symbols in the subframe. Communications can be transmitted to the network entity over resources specified in the uplink resource grant during the TTI.
Abstract:
A satellite terminal and a machine-implemented method are provided for encoding a burst header of a burst for transmission on an inroute. One component of a group of satellite terminal components consisting of an ASIC, a FPGA, and a DSP, generates a burst header having five information bits encoded therein. The five information bits may be encoded using a Reed-Muller code, a (32, 5) block code or a convolutional code having a code rate of either 1/5 or 1/10. The five information bits may represent one or more of a modulation type for a payload of the burst, a code rate for encoding the payload, a code type, and a spreading factor for spreading the payload during transmission. A satellite gateway and a machine- implemented method are also provided for decoding a burst header of a burst received on an inroute as described above.
Abstract:
A transceiver configured to select channel state information for fast link adaptation in a communication system. The transceiver includes a radio frequency unit coupled to a processing apparatus and a memory. The processing apparatus is configured to generate channel and noise covariance estimates and cyclic redundancy check results based on a received data signal; generate a set of Link Quality Metric (LQM) based on the estimates; buffer the generated set of LQM; use a Gaussian Processes (GP) system model to update model parameters based on the buffered set of LQM and the set of CRC results; use the updated model parameters with the GP system model to predict a block error rate (BLER) for each CSI in a set of supported CSI based on the generated set of LQM; selecting from the set of supported CSI the CSI having a maximum throughput and the predicted BLER below a threshold.
