Provided are a method and device for determining a transmission mode, a storage medium and an electronic device. The method includes acquiring information for determining the transmission mode, where the information includes at least one of: service profile information about a first service from an upper layer of a first terminal or an application layer of the first terminal, access layer information about the first terminal, transmission parameter information configured for the first terminal by a base station, or capability information about a second terminal of a proximity service; and determining the transmission mode according to the information. This can solve the problem in the existing art of how to perform communication better when there are UEs of different types or different capabilities in a system.

Example information transmission methods and apparatus are described. One example method includes receiving higher layer signaling and downlink control information. A time-frequency resource corresponding to scheduling request (SR) information and a time-frequency resource corresponding to hybrid automatic repeat request (HARQ) information are respectively determined based on the higher layer signaling and the downlink control information; The SR information is sent by using a first time-frequency resource, and the HARQ information is sent by using a second time-frequency resource. The first time-frequency resource is a part of the time-frequency resource corresponding to the SR information and does not overlap the second time-frequency resource in time domain, and the second time-frequency resource is the time-frequency resource corresponding to the HARQ information. Alternatively, the HARQ information is sent by using the time-frequency resource corresponding to the HARQ information, where the SR information is not sent.

A relay node receives a data block containing multiplexed data streams intended for multiple user equipment (UE) devices being served by the relay node. The relay node extracts the data streams from the data block and allocates them each to a separate narrowband channel that is associated with a particular UE device. The relay node repeatedly transmits the narrowband channels to the UE devices in a broadcast transmission that is transmitted for a predetermined number of repetitions. Each UE device decodes their own respective narrowband channel to obtain the data stream intended for the UE device associated with a particular narrowband channel. A feedback mechanism is utilized by the relay node to determine whether to retransmit a data packet or a new data packet in subsequent broadcast transmissions.

This document describes methods, devices, systems, and means for a switching scheme for opting in and out of multi-user orthogonal frequency-division multiple access (MU-OFDMA). In one aspect, an electronic device enters the MU-OFDMA mode to communicate via a wireless network over a shared-channel bandwidth. During the MU-OFDMA mode, the electronic device determines that an uplink-queue size is greater than a first threshold size. Responsive to the determining, the electronic device opts out of the MU-OFDMA mode and enters a single-user mode to contend for a transmit channel for transmitting uplink data.

A communication system includes: a transmitting-side terminal; a transmitting-side communication apparatus configured to receive data transmitted by the transmitting-side terminal and transmit the received data by radio transmission to a receiving-side communication apparatus; and the receiving-side communication apparatus configured to transmit the data received by radio transmission from the transmitting-side communication apparatus to a receiving-side terminal. The transmitting-side terminal includes a control unit configured to control a transmission speed of the data addressed to the receiving-side terminal based on a first error rate that is an error rate of radio transmission from the transmitting-side communication apparatus to the receiving-side communication apparatus and a second error rate that is an error rate of transmission from the transmitting-side terminal to the receiving-side terminal.

A base station determines a temporal filter configuration for a user equipment (UE) and transmits the temporal filter configuration to the UE. The temporal filter configuration indicates whether the UE should apply a temporal filter to channel state information (CSI) measurements to generate CSI values, or identifies which temporal filter to apply. The UE generates CSI values based on the temporal filter configuration and reports the generated CSI values to the base station.

A data link error feedback signaling system includes a transmitting network device and a receiving network device. The receiving network device may be operable to receive a network data unit from the transmitting network device over a data link, detect an error in the network data unit, and provide data link integrity information based on the error to the transmitting network device. The receiving network device may provide the data link integrity information by marking the data link flawed in a routing protocol, transmitting the data link integrity information via an informational protocol, and so on. The transmitting network device may respond to the data link integrity information, such as by marking the data link less preferred, marking the data link down, transmitting an alarm regarding the data link to a network operator, omitting taking an action upon determining that errors are below an error threshold, and so on.
