The present invention is applicable to the field of communications technologies, and provides a repeating method of a wireless repeating device and a wireless repeating device. The method includes the following steps: synchronizing network connection information of an upstream AP to a downstream WLAN AP interface of the wireless repeating device; obtaining, according to the downstream WLAN AP interface corresponding to the synchronized upstream AP, downstream wireless STA MAC address information, and establishing an upstream WLAN Client interface which is in a mapping relationship with an STA MAC address; and performing, according to the mapping relationship between the STA MAC address and the established upstream WLAN Client interface, management on data forwarded between the upstream AP and a downstream wireless STA.

A communication control method is disclosed, including: connecting, by a small cell by using a built-in soft SIM card or an inserted SIM card, to a Uu air interface of a macro cell to access the macro cell; after receiving a broadcast synchronization signal of the macro cell, synchronizing, by the small cell, with the macro cell, and acquiring configuration information of the macro cell; and performing, by the small cell, system configuration for the small cell according to the configuration information of the macro cell. A SIM card is added to the small cell, so that the small cell can access a macro cell in a terminal form, which is equivalent to addition of a Uu air interface between the small cell and the macro cell. Therefore, configuration management, performance optimization, admissible subscriber configuration, and the like are implemented for the small cell by using this air interface.

Disclosed herein is an architecture for a Digital Capacity Centric Distributed Antenna System (DCC-DAS) that dynamically manages and distributes resources in different locations where there is demand for capacity. The DCC-DAS also allows for the routing of resources to other applications such as location finding devices, jamming devices, repeaters, etc.

Embodiments of the present application provide a method and apparatus of communication between a terminal and a base station. The communication method between a terminal and a base station performed by the terminal includes: sending, by the terminal, a network access request frame with a first preamble to a relay device. The relay device may be configured to receive the network access request frame according to the first preamble, send the network access request frame with a second preamble to the base station, and receive a network access response frame returned by the base station. The length of the second preamble may be smaller than that of the first preamble. The communication method may further includes receiving, by the terminal, the network access response frame sent by the relay device.

Certain aspects of the present disclosure provide compression schemes for relaying prior to decoding. A method that may be performed by a wireless relay node includes receiving, from a transmitter node, a first packet intended for a receiver node, compressing pre-decoded samples of the first packet according to a compression scheme, and transmitting, to the receiver node, a second packet including the compressed pre-decoded samples.

Methods, systems, and devices for wireless communication are described. A relay wireless node may receive, during a first transmit time interval (TTI), a data message to be forwarded to a wireless node. The relay wireless node may forward the data message to the wireless node during the first TTI. The relay wireless node may receive, during a second TTI, a feedback message from the wireless node. The relay wireless node may retransmit the feedback message during the second TTI.

Various aspects of the present disclosure generally relate to wireless communication. A source user equipment (UE) may transmit, to a relay UE, information identifying that the relay UE is one of a plurality of relay UEs selected for cooperative relaying of a communication from the source UE to a destination UE. A channel between the source UE and the relay UE may be one of a plurality of channels comprising a channel between the source UE and each relay UE of the plurality of relay UEs. The plurality of relay UEs may be selected based at least in part on a degree of correlation of the channel between the source UE and the relay UE with at least one other channel of the plurality of channels. The UE may transmit the communication to the plurality of relay UEs for cooperative relaying to the destination UE. Numerous other aspects are described.
