Embodiments of a method and apparatus for wireless communications are disclosed. In an embodiment, a wireless relay device includes a wireless transceiver configured to receive, from a first wireless device, communications data, and a controller configured to determine whether to forward the received communications data to a second wireless device.

Various aspects of the present disclosure relate to receiving a configuration message for random access channel (RACH) transmission, the configuration message comprising a plurality of RACH configuration indices and a set of thresholds; selecting a first RACH configuration index based on a comparison of at least one reference signal measurement to the set of thresholds; and transmit, to a base station, a first RACH preamble having a preamble format based on the first RACH configuration index, wherein the preamble format comprises a long preamble format for extended coverage or a short preamble for basic coverage.

The application is aimed at scenarios such as smart grids, and users are easily blocked by obstacles. A smart reflecting surface assisted non-orthogonal multiple access system power distribution method and system for ultra-reliable low-latency users are proposed, specifically including establishing a communication system model between the base station, the smart reflecting surface and the ultra-reliable low-latency users; according to the current smart reflecting surface phase shift vector and power distribution and decoding order, taking the sum rate of users as the optimization target, the optimal reflecting surface phase shift vector and power distribution are obtained; the reflecting surface phase shift vector satisfying the rank constraint is obtained according to the Gaussian randomization; whether the condition of completing iteration is met is judged. The advantages of the smart reflecting surface extended coverage and the non-orthogonal multiple access system throughput are combined, the reliability of the system is improved, and the total rate performance of the user is improved.

Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may receive a configuration (for example, via control signaling) of a set of reconfigurable intelligent surfaces (RISs). The UE may select a primary RIS for bidirectional wireless communication (for example, uplink and downlink) and one or more secondary RISs for unidirectional wireless communication (for example, downlink) based on the configuration. The UE may use the one or more secondary RISs to enable higher throughput and extended coverage in the wireless communication system, for example, for downlink. The UE may communicate with the base station using the primary RIS, or the secondary RIS, or both.

A communications access point may provide access to a wireless communications network to a user device located at a first location. The communications access point may determine that the user device is moving from the first location to a second location where access to the wireless network is limited or not available. In response to the determination, the communications access point may provide access to the wireless network at the second location by extending a coverage area of the wireless network.

A new generation of network resource management architecture for coverage is provided, which constructs a structure of “signal coverage+capacity coverage” by incorporating satellite, space-based, and ground access points to achieve large-scale regional signal coverage and local area capacity coverage. In the core network, a global resource orchestrator is added, and in the access network, local resource orchestrator and virtual network management and maintenance unit are added for multiple functional units of resource management and control. In terms of coverage structure, it is divided into three-dimensional dense capacity coverage and three-dimensional global signal coverage. The former consists of ground dense network and aerial ad-hoc network, respectively realizing high traffic density coverage and large connection three-dimensional coverage. The latter consists of ground network and satellite constellation, respectively realizing extended coverage towards low altitude and three-dimensional coverage towards space, sky, ground, and ocean.
