A method includes obtaining, by a first terminal device, second uplink data of a second terminal device, performing, by the first terminal device, joint coding processing on first uplink data of the first terminal device and on the second uplink data, where the performing the joint coding processing generates jointly coded data that is based on the first uplink data and the second uplink data, and transmitting, by the first terminal device, the first uplink data and the jointly coded data to a network device, where the first uplink data is transmitted to the network device separately from the jointly coded data. The first uplink data may be transmitted on a first transmission resource, and the jointly coded data to the network device may be transmitted on a second transmission resource different from the first transmission resource.

Measurements and Channel State Information (CSI) feedback are configured using communications between a network and user equipment (UE). The communications includes a first signaling from a network component to the UE indicating one or more reference signal (RS) resource configurations, a second signaling indicating one or more interference measurement (IM) resource configurations, and a third signaling indicating a CSI report configuration, wherein the CSI report configuration indicates a subset of the one or more RS resource configurations and a subset of the one or more IM resource configurations. The UE establishes a RS based measurement according to the subset of the one or more RS resource configurations and an IM according to the subset of the one or more IM resource configurations. The UE then generates and sends to the network a CSI report in accordance with the CSI report configuration and using the RS based measurement and the IM.

A wireless communication system comprises a source node, a destination node, and a plurality of half-duplex relay nodes disposed between the source node and the destination node. The half-duplex relay nodes are configured in two disjoint paths each comprising an equal number of hops from the source node to the destination node. The source node is configured to alternately transmit information via the two disjoint paths in alternating time slots, and the destination node is configured to alternately receive information via the two disjoint paths in alternating time slots.

One disclosure of the present specification provides a method for operating a HARQ from user equipment (UE). The method comprises the steps of: the UE receiving downlink data from each cell, when at least one TDD-based cell and at least one FDD based cell are established according to carrier aggregation (CA), a specific TDD-based cell is established as a primary cell of the carrier aggregation (CA), and the at least one FDD-based cell is established as a secondary cell of the carrier aggregation (CA); the UE confirming a PUCCH format to be used for transmitting a HARQ ACK/NACK for the downlink data; and the UE determining the number of bits for transmitting the HARQ ACK/NACK when use of the specific PUCCH format for transmitting the HARQ ACK/NACK is confirmed.

A relaying method in a telecommunication system having a plurality of sources, a half-duplex relay relay and a recipient. The relay performs a receiving phase of: receiving codewords transmitted by the sources, including estimating for each source a message associated with the codewords transmitted by the source, error detection and decision of error-free decoded messages, which determine the set of sources decoded without error by the relay; a phase of coding and transmitting to the recipient a signal uniquely representative of the selection of messages, such that, after each reception of a block from different sources, the relay receives and decodes a return path from the destination indicating if no or at least one message is decoded without error, these messages determining the set of sources decoded without error. The relay switches from the receiving phase to the coding and transmission phase once a logic rule is valid.

The base station includes an encoder that encodes a first set of bits of MTC information with a first coding rate and encodes a second set of MTC information bits with a second coding rate. The first set and second set of bits are modulated using layered modulation and broadcast within the service area of the base station in a first transmission such that the first set of bits can be recovered using the low modulation order and the second set of bits can be recovered using the high modulation order. A relay station receives, demodulates and decodes the first transmission to recover at least the second set of bits. The relay station transmits a second set transmission including at least the second set of bits to at least one MTC device that did not recover the second set of bits from the first transmission.

Embodiments provide methods, systems, and apparatuses for multicast broadcast multimedia service (MBMS)-assisted content distribution in a wireless communication network. A proxy terminal may include an MBMS access client configured to receive and cache an MBMS transmission including media data and metadata. The proxy terminal may further include a hypertext transfer protocol (HTTP) server module configured to transmit at least a portion of the media data to a user equipment (UE) of the wireless communication network via an HTTP transmission. The media data and metadata may be in a dynamic adaptive streaming over HTTP (DASH) format.
