Method and apparatus for coordinating multi-user multi-access point transmissions
Aspects of the present disclosure generally relate to a wireless communication method in a wireless network comprising a plurality of access points (APs) sharing a communication channel, each AP is configured to manage stations of a basic service set (BSS), the method comprising at a coordinator AP: signaling to another AP, referred to as coordinated AP, that the coordinator AP has gained access to the communication channel; and sending to the coordinated AP a resource allocation allocating a chunk of the communication channel for stations managed by the coordinated AP.
Wireless device reconfiguration procedure by a base station central unit
A base station central unit transmits, to a wireless device via a base station distributed unit, configuration parameters of the wireless device. The base station central unit receives, from the wireless device via the base station distributed unit, a confirmation of at least one of the configuration parameters. The base station central unit transmits, to the base station distributed unit, an indication that the wireless device successfully performed a reconfiguration procedure based on the configuration parameters. The base station central unit communicates, with the wireless device via the base station distributed unit, based on the configuration parameters.
Method and apparatus for controlling interference from controllable device
The present disclosure provides a method and apparatus for controlling interference from a controllable device. The method includes that: a target RB suffering interference from a controllable device is determined from all RBs for data transmission; a target notification message is generated, the target notification message containing an interference indication identifier and RB information of the target RB and the interference indication identifier being configured to indicate that the interference is from the controllable device; and the target notification message is transmitted to a target base station to reduce the interference from the controllable device over the target RB according to the target notification message, the target base station being a base station for providing service for the controllable device. According to the present disclosure, interference from a controllable device over a base station of a cellular network may be reduced.
Method and apparatus for configuring carrier aggregation for serving cells having different start time points in frame in wireless communication system
The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. According to the disclosure, a base station may configure serving cells having different frame start time points, using carrier aggregation (CA), for operation of a terminal, and thus can increase the transmission rate of the terminal.
PDCCH MONITORING IN UNLICENSED SPECTRUM FOR A TERMINAL DEVICE WITH A SINGLE ACTIVE PANEL
According to an aspect, there is provided a terminal device configured to perform the following. Initially, the terminal device monitors physical downlink control channel, PDCCH, transmissions according to a first set of rules. The first set of rules comprises rules for performing monitoring over at least two beam pair links, each beam pair link corresponding to a control resource set, CORESET, with a different active transmission configuration indication, TCI, state. The terminal device receives, using a first CORESET with a first active TCI state from an access node, an indication for limiting monitoring and consequently limits monitoring of PDCCH transmissions associated with CORESETs having a TCI state other than the first active TCI state for a period of time.
AGGREGATED COMMUNICATION NETWORK
An aggregated communication network includes one or more communication networks and a plurality of network nodes arranged in a plurality of hierarchical layers, the network nodes including a central node at a highest layer and a remaining network nodes being arranged, as part of the one or more communication networks, in layers below the highest layer, with one or more spatially distributed network nodes at each layer below the highest layer. The network nodes in each communication network are interconnected in a tree-like structure via communication links, with respective sub-branches extending from the network nodes via network nodes in lower layers. The one or more communication networks are connected to the central node in a star-like structure via respective communication links between the central node and respective network nodes in a next-to-highest layer. The communication links between network nodes in a lowest layer.

Particularly, a method by which a terminal receives a PDSCH comprises the steps of: receiving configuration information, the configuration information including (i) first information for configuring semi-persistent downlink transmission and (ii) second information related to control resource sets (CORESETs), the first information including a plurality of configurations related to downlink semi-persistent scheduling (SPS), and (i) a first CORESET, which corresponds to a first CORESET group index, and (ii) a second CORESET, which corresponds to a second CORE SET group index, being configured on the basis of the second information; receiving first downlink control information (DCI) based on the first CORESET and second DCI based on a second CORESET, the semi-persistent downlink transmission being activated on the basis of the first DCI and/or the second DCI; and receiving a semi-persistent scheduling PDSCH on the basis of the activation, the SPS PDSCH being associated with a CORESET group index corresponding to a CORESET, which has received DCI by which the semi-persistent downlink transmission is activated.
Power control in wireless communications
A system, a method, and a computer program product for power control using uplink coordinated multi-point transmission in a wireless communications system are provided. Using a first node, at least one second node configured to provide an uplink support to user equipment communicating with the first node is detected. The first node receives a confirmation from the second node indicating availability of uplink support by the second node to the user equipment. Based on the received confirmation, communicating with the user equipment on an uplink using the second node is established.
MODULATION ORDER OF A FRACTION OF PDSCH SYMBOLS FOR PHASE NOISE HANDLING
The base station may transmit to the UE, a first part and a second part of a PDSCH. The UE may decode the second part of the PDSCH. The first part of the PDSCH may be associated with a higher MCS than the second part of the PDSCH. The UE may estimate at least one of an ICI or a CPE associated with the PDSCH based on the decoding of the second part of the PDSCH. The UE may decode the first part of the PDSCH based on the decoding of the second part of the PDSCH. Decoding the first part of the PDSCH based on the decoding of the second part of the PDSCH may include correcting for the at least one of the ICI or the CPE associated with the PDSCH.
Signaling of random access preamble parameters in wireless networks
User equipment (UE)-initiated accesses within a cellular network are optimized to account for cell size and to reduce signaling overhead. A fixed set of preamble parameter configurations for use across a complete range of cell sizes within the cellular network is established and stored within each UE. A UE located in a given cell receives a configuration number transmitted from a nodeB serving the cell, the configuration number being indicative of a size of the cell. The UE selects a preamble parameter configuration from the fixed set of preamble parameter configurations in response to the received configuration number and then transmits a preamble from the UE to the nodeB using the preamble parameter configuration indicated by the configuration number.
