Methods, systems, and devices for wireless communications are described. In some examples, a base station may identify one or more communication paths to a user equipment (UE), and may determine an end-to-end signal quality for each communication path (e.g., a signal-to-noise ratio (SNR)), one or more hop SNR values for each hop of each communication path, a ratio of the hop SNR values and the end-to-end SNR of each communication path, or a combination thereof. Based on the determined SNR values, ratios, or both, the base station may select a first communication path for a first type of communications (e.g., uplink, downlink, signal type, or the like) and a second communication path for a second type of communications (e.g., uplink, downlink, signal type, or the like), and may communicate with the UE using the selected communication paths.

Aspects described herein relate to determining a group of relaying user equipment (UEs), selecting a sub-channel of multiple sub-channels for transmitting, to the group of relaying UEs, quality-of-service (QoS) traffic along with one or more other transmitting UEs in the time duration, and transmitting the QoS traffic to the group of relaying UEs in the same time duration over the sub-channel.

For example, a communication link between a first relay node and a second relay node, which are in synchronous movement, is established. Beam management assistance information from the first relay node is received at the second relay node upon an occurrence of beam failure at the first relay node (S801). At the second relay node it is decided about a timing at which the received beam management assistance information is to be transmitted to a serving network node (S802), and the received beam management assistance information is transmitted from the second relay node to the serving network node at the decided timing (S803).

A method of controlling communications within a wireless communications network is provided. The method comprises receiving, at a first infrastructure equipment acting as a donor node connected to a core network part of a wireless communications network, signals representing data from one or more others of infrastructure equipment, the data having been received at the one or more others of the infrastructure equipment from one or more communications devices or from other infrastructure equipment, and transmitting, by the first infrastructure equipment, the data from the one or more others of the infrastructure equipment to the core network part of the wireless communications network. At least one of the infrastructure equipment uses at least one spectral efficiency enhancing technique to receive the signals, the at least one spectral efficiency enhancing technique allowing the at least one infrastructure equipment to receive the signals in the backhaul communications link.

Apparatus and methods for providing enhanced coverage in a quasi-licensed wireless system using a reduced-cost base station apparatus. In one embodiment, the base station is configured to utilize quasi-licensed 3.55-3.70 GHz CBRS (Citizens Broadband Radio Service) GAA and PAL spectrum, and employs a power amplifier sharing arrangement in its transmitter chain(s), along with multi-sector antenna elements. A scheduling algorithm operative on the base station generates sector-specific weights which are used to allocate the shared power amplifier(s) between the different sectors. Advantageously, design and production costs of the base station are reduced through sharing of comparatively expensive amplifier and transmitter chain components, thereby allowing for commoditization of the base station for mass distribution.

A time domain resource indication method includes sending, by a first node, first time domain resource configuration information to at least one second node. The first time domain resource configuration information is used by the at least one second node to determine second time domain resource configuration information sent by the at least one second node to at least one third node. The first time domain resource configuration information indicates first time domain resources of a link between the first node and the at least one second node. The second time domain resource configuration information indicates second time domain resources of a link between the at least one second node and the at least one third node.

The present disclosure relates to a node (AP2, U11) in a wireless communication system (1), where the node (AP2, U11) is adapted to communicate with at least two other nodes (AP1, AP0) in the wireless communication system (1), and where the other nodes (AP1, AP0) are first type nodes (AP1, AP0) which are adapted to communicate with each other by means of backhaul communication. The node (AP2, U11) is adapted to receive a signal (xA) transmitted from an adjacent first type node (AP1), where the (xA) has been forwarded from at least one farther first type node (AP0). In case of unsuccessful decoding of the signal (xA), the node (AP2, U11) is adapted to request re-transmission (NACK) of the signal (xA), and to receive a re-transmission of the signal (xA) directly from a farther first type node (AP0).

A system for providing communication in a distributed land mobile radio (LMR) system architecture. In some embodiments, the system includes a first controller associated with an LMR site. The first controller may be configured to control communication, via a communication channel, of a plurality of LMRs. In some embodiments, the system further includes a first repeater of a plurality of repeaters associated with the LMR site. The first repeater may include at least an active mode. The first repeater may be in the active mode to initiate a simulcast controller operation using the communication channel of the plurality of repeaters.

A cellular communication system supports network slicing and has a network relay function (140) for managing the indirect connections. A mobile device (110) may send a request message to a relay device (120), the request message including a slice to access. A response message indicates available slice(s) and relay device(s). The device selects a slice and/or relay device in dependence of the response message. The relay device receives the request message and sends a transfer request message to the cellular communication system indicating a request to transfer data via an indirect connection and including the requested slice, and sends the response message. The network relay function receives the transfer request message, obtains relay capability data regarding relay device(s) capable of data transfer for available slice(s) in dependence of the requested slice; and sends a transfer response message including network relay information indicating the available relay device(s) that can serve as relay device for indirect communication with the requested network slice.
