Embodiments of this disclosure relate to the communications field, and provide a repeated transmission method and an apparatus, to increase a probability of successful decoding of a user equipment. The method includes: performing, by a user equipment, first transmission of uplink data, and sending a first reference signal to a network device based on a first transmit power, where the first reference signal is used to demodulate the first transmission of the uplink data; and performing, by the user equipment, N.sup.th transmission of the uplink data, and sending a second reference signal to the network device based on a second transmit power, where N is an integer greater than or equal to 2, the second reference signal is used to demodulate the N.sup.th transmission of the uplink data, and the second transmit power is less than the first transmit power.

A donor communication station transmits a unicast transmission comprising a plurality of device data sets where each device data set directed to each of a plurality of user equipment (UE) devices. A relay node receives the unicast transmission and retransmits the data sets in a broadcast transmission over a broadcast communication channel to the plurality of UE devices. In one example, the donor communication station encodes data for multiple user equipment (UE) devices by applying broadcast encoding to the data for each device before applying outer encoding to the data. The dual encoded data is transmitted to the relay node over a dedicated channel. The relay node applies outer decoding to the dual encoded data to retrieve the broadcast encoded data. The relay node then transmits the broadcast encoded device data in a broadcast transmission without outer encoding.

A signal analysis apparatus for analyzing an input signal is described. The input signal includes a symbol sequence. The symbol sequence includes data information and redundant data information. The signal analysis apparatus includes one or more circuits composed of a decoder module, an error correction module, and a processing module. The decoder module is configured to decode the input signal, thereby obtaining a decoded input signal. The error correction module is configured to identify at least one error in the decoded input signal. The processing module is configured to generate a data set. The data set includes information on the at least one identified error. The data set further includes information on at least one of a portion of the input signal being associated with the error and a portion of the decoded input signal being associated with the error. Further, a signal analysis device and a signal analysis method are described.

Embodiments of the present invention provide an uplink control information sending method, an uplink control information receiving method, an apparatus, and a system. The method includes: receiving, by a terminal device, channel indication information from an access network device on a physical control channel; determining the channel resource set that is of N channel resource sets and that matches a type or a size of the UCI as a first channel resource set; determining a channel resource that is in the first channel resource set and that is indicated by the channel indication information; and sending uplink control information UCI to the access network device on the channel resource. A quantity of bits that need to be added to the channel indication information in the embodiments of the present invention is less than that in the prior art.

Methods and apparatuses are disclosed herein for ascertaining reliability aspects for Device-to-Device (D2D) links prior to actual data transmission. In some embodiments, a method performed by a second Wireless Communication Device (WCD) comprises attempting to receive synthetic packet transmissions, each comprising R replicas of a respective synthetic packet, from a first WCD over a direct or indirect D2D link using a current resource allocation. The method further comprises determining that the D2D link violates a requirement based on results of the attempting to receive the synthetic packet transmissions and sending a violation notification to a Centralized Scheduler (CS). Corresponding embodiments of a second WCD are also disclosed. Embodiments of a method of operation of a first WCD and corresponding embodiments of the first WCD as well as embodiments of a method of operation of a CS and corresponding embodiments of the CS are also described herein.

A resource determination method and apparatus, a node and a non-transitory computer-readable storage medium are disclosed.
