Methods and devices utilizing sidelink transmission between user equipment (UEs) for HARQ retransmission are provided. The sidelink HARQ retransmissions include data from the initial transmission or an outer coded version thereof. HARQ feedback from the targeted receiver of the initial transmission may identify code block groups and/or individual code blocks the target receiver did not successfully decode. A UE that has not successfully decoded an entire transport block, may still cooperate in HARQ retransmission for the targeted receiver of the transport block by retransmitting at least a subset of the code block groups that it was able to successfully decode for the transport block.

Provided are systems, methods, and computer-program products for a proxy network that can determine, for a set of objects, an initial differential, where the initial differential is determined using a rules data store of a host network. The proxy network can further determine a supplemental differential for the set of objects. The proxy network can further determine a final differential that is the sum of the initial differential and the supplemental differential. The proxy network can further determine a final sum for the set of objects that is the object value less the final differential. The proxy network can further generate an outbound data packet that includes values corresponding to the set of objects and the final sum. When the host network receives the outbound data packet, the host network can modify an object data store using the values corresponding to the set of objects and the final sum.

A technology related to a distributed antenna system is disclosed. In an exemplary embodiment, a distributed antenna system may include a master unit and a plurality of remote units. The master unit may be interfaced with a wireless communications network and perform a bidirectional simultaneous digital radio frequency distribution of a wireless signal. The plurality of remote units may be each coupled to the master unit, and each perform a wireless transmission or reception of a split radio frequency signal to or from terminals located within a coverage. The master unit and the plurality of remote units may transmit or receive digital radio frequency signals in a wavelet transform domain. The master unit may determine whether the digital radio frequency signal, transmitted by each of the remote units, is normal, and merge the digital radio frequency signals.

A data transmission method of a source node in a cooperative communication system includes: performing a beamforming to a relay node; transmitting data to the relay node; performing a beamforming to a destination node; and transmitting data to the destination node.

A base station includes a transmitter which transmits an offset value for a transmission power of a sounding reference signal (SRS) to a terminal apparatus; and a receiver which receives the SRS at the transmission power controlled by the terminal apparatus. The offset value used to control the transmission power is set within one of a first offset setting range having a first lower limit value and a first upper limit value and a second offset setting range having a second lower limit value and a second upper limit value. A difference between the first and second lower limit values equals a difference between the first and second upper limit values. A step width of the offset values within the first offset setting range equals a step width of the offset values within the second offset setting range. The SRS is a periodic SRS (P-SRS) or an aperiodic SRS (A-SRS).

Technology for a user equipment (UE) operable to adjust a receiver timing is disclosed. The UE can decode a plurality of channel-state information reference signals (CSI-RSs) received from a plurality of cooperating nodes, wherein the plurality of cooperating nodes are included in a coordination set of a Coordinated MultiPoint (CoMP) system. The UE can generate a plurality of received RS timings from the plurality of CSI-RSs, wherein the received RS timings represent timings from the plurality of cooperating nodes. The UE can determine a composite received RS timing from the plurality of received RS timings. The UE can adjust the receiver timing based on the composite received RS timing.
