The technologies described herein are generally directed to changing error mitigation protocols used for a connection based on the quality of a network connection in a fifth generation (5G) network or other next generation networks. For example, a method described herein can include determining, by network equipment comprising a processor, that a quality of a connection between a user equipment and a network access point is below a connection quality threshold, with the connection employing a communications protocol using a first error mitigation process, and where the network access point enables respective access to services enabled via a communication network. The method can further include, based on the quality and the first error mitigation process, enabling, by the network equipment, a second error mitigation process of the communications protocol of the connection, the second error mitigation process being different than the first error mitigation process.

In one embodiment, information passing mechanism between the two connected optical transceivers is provided. Within the first optical transceiver, Rx 1 calculates the current condition of the uplink channel and passes this information together with the condition of the downlink channel that it receives from Tx 2 to Tx 1. The Tx 1 uses the downlink channel condition that it receives from the Rx 1 to generate signal with appropriate modulation format, shaping factor, baudrate and coding scheme for maximizing the downlink's capacity. The Tx 1 then transmits this information together with the uplink channel condition received from Rx 1 to Rx 2. The Rx 2 uses the information about the modulation format, baudrate, shaping factor and coding scheme that it receives from Tx 1 for the reception of information-bearing signal. The Rx 2 then calculates the transmission channel condition of the downlink channel and passes this information together with the uplink channel condition that it receives from Tx 1 to Tx 2. The Tx 2 then uses the uplink channel condition that it receives from the Rx 2 to generate signal with optimized modulation format, shaping factor, baudrate and coding scheme for maximizing the uplink's capacity. The information exchange process between the two connected optical transceivers then repeats in an endless loop.

A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns include a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

A base station may generate first configuration information to configure a first user equipment (“UE”) to operate using a first bandwidth within a wideband carrier of a cell, generate second configuration information to configure a second UE to operate using a second bandwidth within the wideband carrier of the cell, and cause transmission of the first and second configuration information to the first and second UEs, respectively. The base station may configure the first and second UEs based upon capabilities received from each UE, respectively.

An uplink control information transmission method and a device. The method includes obtaining a first modulation and coding scheme offset value used to multiplex first uplink control information on a physical uplink shared channel, where the first modulation and coding scheme offset value is less than 1, and mapping, according to the first modulation and coding scheme offset value, the first uplink control information to a resource for the physical uplink shared channel, to transmit the first uplink control information to a network device using the resource for the physical uplink shared channel.

Methods, systems, and devices for wireless communications are described. Different periodicities may be dynamically selected when monitoring and transmitting signaling used for link management, where respective periodicities may be based on the quality of the link between devices. For instance, a first wireless device may use a first monitoring periodicity to monitor for signals transmitted from another wireless device. Upon determining that a link condition has changed (e.g., decreased or reached a threshold), the first wireless device may decrease its monitoring periodicity (and increase monitoring frequency) to detect signals transmitted by the other wireless device more frequently. In such cases, the other wireless device may likewise transmit its measurement signals more often (e.g., in accordance with a second periodicity) based on the link quality. The adjusted monitoring and transmission periodicities may provide additional occasions for the wireless device to detect signals from another device.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for improving communication throughput despite periodic blockages. In some implementations, a method includes receiving, by a receiver and from a transmitter, code blocks transmitted according to a first set of communication parameters that includes one or more first interleaver parameters used to interleave information in the code blocks prior to transmission. Corrupted portions of at least some of the received code blocks are identified. A blockage duration and a blockage interval of a blockage of communication channel between the transmitter and the receiver are determined based on the corrupted portions of the received code blocks. A second set of communication parameters that includes one or more second interleaver parameters are determined based on the blockage duration and blockage interval. The second set of communication parameters are communicated to the transmitter for subsequent transmissions by the transmitter to the receiver.

Techniques are disclosed for an adaptive and causal random linear network coding (AC-RLNC) with forward error correction (FEC) for a communication channel with delayed feedback. An example methodology implementing the techniques includes transmitting one or more coded packets in a communication channel, determining a channel behavior of the channel, and adaptively adjusting a transmission of a subsequent coded packet in the first channel based on the determined channel behavior. The communication channel may be a point-to-point communication channel between a sender and a receiver. The channel behavior may be determined based on feedback acknowledgements provided by the receiver. The subsequent coded packet may be a random linear combination of one or more information packets.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure one or more transmission parameters based at least in part on an average channel condition estimate for a broadcast channel, wherein the broadcast channel is for broadcast communications or groupcast communications for multiple mobile UEs. The UE may transmit a broadcast communication or a groupcast communication using the one or more transmission parameters. Numerous other aspects are described.
