Terminal, radio communication method, base station and system for transmitting physical uplink shared channel based on time domain resource allocation list
A user terminal according to an aspect of the present disclosure includes a receiving section that receives downlink control information (DCI) indicating transmission of an uplink shared channel, and a control section that determines that a size of a time domain resource allocation (RA) field included in the DCI is different depending on a format of the DCI to control the transmission of the uplink shared channel based on the field. According to one aspect of the present disclosure, the number of candidates of the PUSCH time domain RA can be appropriately controlled.
Frequency division multiple access optical subcarriers
A network or system in which a hub or primary node may communicate with a plurality of leaf or secondary nodes. The hub node may operate or have a capacity greater than that of the leaf nodes. Accordingly, relatively inexpensive leaf nodes may be deployed to receive data carrying optical signals from, and supply data carrying optical signals to, the hub node. One or more connections may couple each leaf node to the hub node, whereby each connection may include one or more spans or segments of optical fibers, optical amplifiers, optical splitters/combiners, and optical add/drop multiplexer, for example. Optical subcarriers may be transmitted over such connections, each carrying a data stream. The subcarriers may be generated by a combination of a laser and a modulator, such that multiple lasers and modulators are not required, and costs may be reduced. As the bandwidth or capacity requirements of the leaf nodes change, the number of subcarriers, and thus the amount of data provided to each node, may be changed accordingly. Each subcarrier within a dedicated group of subcarriers may carry OAM or control channel information to a corresponding leaf node, and such information may be used by the leaf node to configure the leaf node to have a desired bandwidth or capacity.
Neural networks and systems for decoding encoded data
Examples described herein utilize multi-layer neural networks to decode encoded data (e.g., data encoded using one or more encoding techniques). The neural networks have nonlinear mapping and distributed processing capabilities which are advantageous in many systems employing the neural network decoders. In this manner, neural networks described herein are used to implement error code correction (ECC) decoders.
Splitting and concatenating of media access control (MAC) protocol data units (PDUs) for direct transport block (TB) forwarding in relaying operations
Certain aspects of the present disclosure provide techniques for direct TB forwarding. In aspects, a relay node receives, from a source node, an indication to directly forward one or more TBs to one or more destination nodes, wherein directly forwarding includes transmitting a TB of the one or more TBs to the one or more destination nodes through only a PHY layer and a HARQ portion of a MAC layer in a protocol stack of the relay node, receives, from the source node, control information for one or more data channels configuring: one DL grant and two or more SL grants, or two or more DL grants and one SL grant, decoding one or more TBs based, at least in part, on the control information, and directly forwards the one or more TBs to the one or more destination nodes based on the indication and the control information.
RADIO COMMUNICATION SYSTEM, RADIO STATION, RADIO TERMINAL, COMMUNICATION CONTROL METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM
A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) or the second radio station (2) transmits constraint information to the radio terminal (3). The constraint information contains an information element necessary to specify a reception constraint and/or transmission constraint related to the first cell (10) and/or the second cell (20) when the carrier aggregation is performed. The reception/transmission constraint is a constraint related to downlink signal reception/uplink signal transmission by the radio terminal over one or more subframe periods of the primary cell (10) and the secondary cell (20). It is thus, for example, possible to contribute to reduction in wasteful power consumption in the radio terminal in the carrier aggregation of a plurality of cells served by different radio stations.
SELECTIVE MAPPING OF CODED MULTI-CHANNEL TRANSMISSION
The present invention provides methods, apparatus and systems for improving a systems-level data rate on a communications link such as the orthogonal frequency division multiplexed multiple access (OFDMA) downlink used in WiFi and LTE cellular/wireless mobile data applications. The present invention preferably uses a form of multilevel coding and decoding known as tiled-building-block encoding/decoding. With the present invention, different receivers coupled to different parallel downlink channels with different channel qualities decode different received signal constellations at different levels of resolution. This allows the downlink of the OFDMA system to operate with a significantly higher data rate, thus eliminating existing inefficiencies in the downlink and significantly increasing system level bandwidth efficiency.
SYSTEM AND METHOD TO MEASURE AND SCORE APPLICATION HEALTH VIA CORRECTABLE ERRORS
Disclosed are systems, methods, and non-transitory computer-readable storage media for monitoring application health via correctable errors. The method includes identifying, by a network device, a network packet associated with an application and detecting an error associated with the network packet. In response to detecting the error, the network device increments a counter associated with the application, determines an application score based at least in part on the counter, and telemeters the application score to a controller. The controller can generate a graphical interface based at least in part on the application score and a timestamp associated with the application score, wherein the graphical interface depicts a trend in correctable errors experienced by the application over a network.
METHODS FOR RELIABLE COMMUNICATION USING PHYSICAL DOWNLINK CONTROL CHANNELS
Methods for receiving and transmitting downlink transmissions with increased reliability are provided. A method includes receiving configuration information defining first and second search space sets. The first search space set includes a first one or more search spaces each including a plurality of physical downlink control (PDCCH) candidates. The second search space set includes a second one or more search spaces each including a plurality of PDCCH candidates. The configuration information indicates that the first and second one or more search spaces are linked. The method further includes receiving downlink control information (DCI) by detecting, based on the received configuration information, a first transmission using PDCCH candidates of the first one or more search spaces, detecting a second transmission using PDCCH candidates of the second one or more search spaces, and decoding at least one of the first transmission or the second transmission.
Systems and Methods for Selective Storing of Data Included in a Corrupted Data Packet
An exemplary hearing device is configured to receive, from a source, a data packet, the data packet including a plurality of frames including a first frame and a second frame. The hearing device determines that the data packet has an invalid checksum. The hearing device accesses, in response to the determining that the data packet has the invalid checksum, a first frame checksum for the first frame and a second frame checksum for the second frame. The hearing device determines that the first frame checksum is invalid and that the second frame checksum is valid. The hearing device discards, based on the first frame checksum being invalid, the first frame and stores, based on the second frame checksum being valid, the second frame.
FORWARD ERROR CORRECTION ADJUSTMENTS FOR C-V2X COMMUNICATIONS
A user equipment (e.g., C-V2X user equipment) can receive a transmission from a network device of a mobile network and decode the transmission using a first forward error correction code. The user equipment can determine an attribute of the transmission to determine a condition of the communication channel. Based on the condition of the communication channel, the user equipment can facilitate transmitting feedback to the network device, wherein the feedback is forwarded through the mobile network to an application server device that selects a second forward error correction code based on the feedback. The second forward error correction code can be transmitted to, and received by, the user equipment. The user equipment can use the second forward error correction code to decode subsequent transmissions.
