An electronic device is provided. The electronic device includes a communication circuit and a processor. The processor may be configured to obtain information on the number of predicted abnormal terminals, allocate different resources respectively to a plurality of terminal groups, wherein the number of the plurality of terminal groups is greater than the number of predicted abnormal terminals, obtain learning data of each of the plurality of terminal groups, and identify a final terminal group among the plurality of terminal groups, based on the learning data.

A communication control device that acquires first interference information indicating a first interference from communication involving a communication node that is not controlled by the communication control device and second interference information indicating a second interference from communication involving another communication node that is controlled by the communication control device. The communication control device classifies the communication nodes into groups related to a decision of a radio resource that is available for use by a communication node based on the first interference information and the second interference information.

Methods, systems, and devices for wireless communications are described. The described techniques enable a first wireless device (e.g., an integrated access and backhaul (IAB) node in an IAB system) or a network entity (e.g., a centralized unit (CU) in the IAB system) to select a set of wireless devices for communication. The first wireless device, the CU, or both may select the set of wireless devices for communication based on a pathloss mode of the first wireless device, whether an angular separation between a group of nodes (e.g., one or more of the set of wireless devices) is less than an angular separation threshold, or both. The first wireless device may communicate with the set of wireless devices with one or more communications beams. For example, the device may communicate with multiple wireless devices using a single communication beam if the angular separation between the multiple devices is relatively low.

Methods, systems, and devices for wireless communications are described in which a user equipment (UE) of a group of UEs may communicate with other members of the group to provide data or other information via sidelinks. The UE may transmit a groupcast sidelink request to the base station. After receiving the sidelink request, the base station may send a sidelink grant (e.g., transmit or receive grant) in downlink control information (DCI) to the UEs in the sidelink groupcast communications group. The sidelink grant may include information for each hop such as which UEs are going to transmit or receive, the reception or transmission beams of the UEs, time and frequency resources, or the data to forward or relay. In some examples, a UE may relay information to other UEs in the sidelink groupcast communications group.

The present disclosure relates to a wireless communication system and, specifically, to a method and a device therefor, the method comprising the steps of: obtaining information on a plurality of search space sets and a plurality of groups including parts of the plurality of search space sets; obtaining information on one group for monitoring a PDCCH from among the plurality of groups; and monitoring the PDCCH on the basis of search space sets which satisfy a pre-defined condition from among search space sets corresponding to the one group, wherein the pre-defined condition includes a condition where the number of PDCCH candidates and the number of non-overlapping control channel elements (CCEs) are less than or equal to specific values.

A method is provided including determining a strength of a channel to each of a plurality of user equipments in a wireless multi-user network; scheduling first downlink resources for transmitting first downlink messages to a first group of the user equipments including the user equipments having the strongest channels; and scheduling second resources for transmitting second downlink messages to a second group of the remaining user equipments using a combination of broadcasting and cooperative relaying.

A method for allocating resources for device-to-device transmission between two or more user equipment (UEs) includes transmitting, from a first UE to a second UE, a resource allocation configuration for device-to-device communications. A resource request for a device-to-device transmission is received from the second UE. In response to the resource request, a resource for the device-to-device transmission is selected at the first UE. A resource grant is transmitted to the second UE. The resource grant identifies the selected resource. A device-to-device transmission is received from the second UE over the selected resource.

A method, a device, and a system for resource allocation are provided to improve network capacities. The method implemented by an access network device includes: obtaining a first quantity of repetitions M and a first MCS order that are of a scheduling resource of a first terminal, and a second quantity of repetitions N and a second MCS order that are of a scheduling resource of a second terminal; calculating overlapping areas of first and second total scheduling resources based on the first and second quantities of repetitions and the first and second MCS orders, respectively; determining a maximum overlapping area of the first total scheduling resource based on the calculated overlapping areas; and allocating to the second terminal, N consecutive scheduling resources overlapping with the first total scheduling resource, wherein an overlapping area is less than or equal to the maximum overlapping area.

Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.
