A method of wireless communication includes, in response to a trigger event detected at a first base station, performing, by the first base station, a scan of a plurality of frequencies for a synchronization signal block (SSB) transmission from a second base station. The plurality of frequencies correspond to a plurality of global synchronization channel numbers (GSCNs) associated with the first base station and the second base station. The first base station is associated with a first coverage area that is at least partially within a second coverage area associated with the second base station. The method further includes transmitting, by the first base station, one or more SSBs having an SSB configuration that is based on a result of the scan.

Proposed are a method and a device for transmitting a signal including a data field in a wireless LAN. For example, an access point (AP) allocates, to a second station, a second frequency band adjacent to a first frequency band, wherein the second frequency band can include a plurality of resource units. In addition, a signal including the data field can be transmitted to the second station through the allocated second frequency band. Furthermore, when the first frequency band is allocated to the first station, the AP can allocate, to the second station, as a null resource unit, a resource unit adjacent to the first frequency band among the plurality of resource units.

A base station transmits and a UE detects broadcast information when the UE operates in a Coverage Enhancement (CE) mode. The base station transmits repetitions of signaling conveying broadcast information in one or more subframes of each frame in a quadruple of frames. The transmission is intermittent in time. To detect the broadcast information, the UE blindly combines and decodes the repetitions of signaling assuming their existence. The base station informs the pattern for the intermittent transmissions of the signaling to UEs connected to the base station or to other base stations.

The present disclosure relates to an apparatus and method for canceling and/or suppressing inter-cell interference in a wireless communication. The method includes: establishing a Radio Resource Control (RRC) connection with a base station through a first serving cell; receiving, at a User Equipment (UE), an RRC message through the first serving cell, the RRC message comprising cell-specific reference signal (CRS) information of a neighbor cell and Physical Downlink Shared Channel (PDSCH) information of the neighbor cell, and the PDSCH information of the neighbor cell comprising a parameter relating to a power ratio of a CRS of the neighbor cell and a PDSCH of the neighbor cell; receiving the PDSCH through the first serving cell; performing a channel estimation for retrieving data from a PDSCH of the first serving cell; and retrieving the data from the PDSCH of the first serving cell based on the second channel estimation.

Provided are an electronic device and method for wireless communication, and a computer-readable storage medium. The electronic device comprises: a processing circuit, configured to: construct an interference overlapping diagram based on an interference/coexistence relationship between resource application systems within a management range, wherein a connection point of the interference overlapping diagram represents one or more resource application systems, and an edge of the interference overlapping diagram represents the fact that interference exists between the resource application systems represented by two connection points linked with the edge; remove one or more edges in the interference overlapping diagram so as to enable the interference overlapping diagram to meet a pre-determined condition after the removal; and carry out channel/resource allocation based on the adjusted interference overlapping diagram.

A system that incorporates the subject disclosure may perform, for example, a method that determines at least one threshold for detecting signal interference in a first plurality of segments occurring in a first radio frequency spectrum of a first wireless communication system, detecting a pattern of recurrence over time of signal interference in a segment of the first plurality of resource blocks according to the at least one threshold, and performing one or more mitigation steps to mitigate the signal interference without filtering the signal interference where the one or more mitigation steps include at least one of transmitting signals out of phase from the signal interference, adjusting transmit power, increasing power in a resource block of a long term evolution communication session, performing beam steering, or changing time parameters for the resource block without changing to a new resource block. Other embodiments are disclosed.

One or more computing devices, systems, and/or methods are provided. In an example, a method includes instantiating a first user equipment (UE) module on a first computing device and instantiating a second UE module on a second computing device connected to the first computing device by a wired network. A first base station (BS) module associated with the first UE module is instantiated on a third computing device coupled to the wired network and a second BS module associated with the second UE module is instantiated on a fourth computing device coupled to the wired network. A first resource allocation map is sent from the first BS module to the second BS module. An interference metric is generated based on the first resource allocation map. A data transmission between the second UE module and the second BS module is modulated based on the interference metric.

A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAC sequence set by a control unit. A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit. The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy to randomize the intra-cell interference.

Embodiments of the present invention relate to a wireless communication system, and more particularly, to a technology for allocating a Channel State Information-Reference Signal (CSI-RS) in a wireless communication system. Embodiments of the present invention provides an apparatus and method for allocating CSI-RSs to resource areas, in which, under the condition of a subframe in which the CP is an extended CP, and the duplex scheme is TDD, if CSI-RSs for maximum 8 antenna ports are allocated, the CSI-RSs are allocated to the 8th and 9th symbols (symbol No. l=7 and 8), wherein each CSI-RS for every two antenna ports is allocated to the same RE while being discriminated from each other by an orthogonal code and neighbor CSI-RS allocated REs in the frequency axis are spaced by an interval of three REs.

A first relay node in a wireless communication system receives, from a second relay node via a backhaul link, coordination information including an index indicating a density pattern of a second phase tracking reference signal (PTRS). The first relay node transmits, to a terminal, configuration information including information on a first subcarrier offset for a first PTRS. The first relay node transmits to the terminal the first PTRS based on the coordination information and the information on the first subcarrier offset. The first subcarrier offset for the first PTRS is different from a second subcarrier offset for the second PTRS.
