An indoor geolocation system for determining a location in three-dimensional space includes a plurality of base stations and a mobile device movable about an indoor environment in three dimensions. The mobile device detects electromagnetic signals in the indoor environment emitted by devices other than the base stations, and generates a signal profile based on the signals. The mobile device transmits the signal profile to one or more of the base stations, which forward the signal profile to a remote server. The system determines a location of the in three-dimensional space of the mobile device by comparing the signal profile to data regarding signal profiles at a plurality of locations in the indoor environment. The data regarding signal profiles in the indoor environment may have been captured by a detection device other than the mobile device at a time prior to the detection of the electromagnetic signals by the mobile device.

A wireless device receives one or more messages comprising spatial relation configuration parameters of a physical uplink control channel. The configuration parameters indicate a plurality of reference signal (RS) sets. An RS set of the plurality of RS sets comprises one or more RSs. A medium access control control element, activating the RS set of the plurality of RS sets, is received. A downlink control information, indicating an RS of the RS set, is received. A spatial domain transmission filter, for the physical uplink control channel, is determined based on based on the RS. Uplink control information is transmitted, via the physical uplink control channel, based on the spatial domain transmission filter.

The disclosure relates to a communication technique for fusing a 5G communication system with IoT technology to support higher data rate after the 4G system and a system thereof. The disclosure may be applied to an intelligent service (e.g., smart home, smart building, smart city, smart or connected car, healthcare, digital education, retail, security and safety related services, etc.) based on 5G communication technology and IoT-related technology. The disclosure discloses a method for allowing a UE to normally receive a MBS service in various scenarios.

A method can include selecting a channel from a network operating according to a first protocol (e.g., an IEEE 802.11ax channel). Designating at least one portion of the channel as a shared resource unit (RU) and another portion as a dedicated RU. When an associated device is communicating according to a different protocol (e.g., a Bluetooth standard), allocating frequencies of the shared RU for use by the associated device and allocating the dedicated RUs for use by the network operating according to the first protocol.

A method for performing wireless communication by a first device and an apparatus for supporting same are provided. The method may comprise: receiving, from a base station, information related to a first sidelink (SL) resource and information related to a first physical uplink control channel (PUCCH) resource; transmitting, to a second device, a medium access control (MAC) packet data unit (PDU) by using the first SL resource, wherein the MAC PDU includes a packet related to a logical channel for which hybrid automatic repeat request (HARQ) feedback is disabled, and wherein the MAC PDU includes no packet related to a logical channel for which HARQ feedback is enabled; determining that retransmission of the MAC PDU is required; and transmitting, to the base station, NACK information by using the first PUCCH resource based on no SL grant available for retransmission of the MAC PDU.

A method and system to help facilitate communication between a user equipment device (UE) and an access node that is serving the UE, in a scenario where a bearer is configured for the UE, the bearer having a defined set of quality-of-service (QoS) requirements for communication of user-plane data on the bearer. When wireless coverage of the UE from the access node is threshold poor, the access node and a supporting core network could interwork to loosen the set of QoS requirements of the bearer in an effort to avoid loss of the bearer. And upon loosening of the set of QoS requirements, the access node could invoke Packet Data Convergence Protocol (PDCP) duplication for the communication between the UE and the access node on the bearer, to help improve quality of the communication between the UE and the access node in presence of the threshold poor wireless coverage.

Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a base station (BS), an indication of a random access (RA) channel (RACH) preamble. The RACH preamble is a member of a first set of RACH preambles reserved for positioning purposes, the first set of RACH preambles is different from a second set of RACH preambles reserved for communication purposes, and the first and second sets of RACH preambles are associated with the BS. The UE detects, while in a radio resource control (RRC) idle or RRC inactive state, a positioning event. The UE transmits, to the BS, the RACH preamble. The UE receives, from the BS, a RA response for positioning purposes that is different from a RA response for communication purposes, the RA response for positioning purposes including a random access preamble identifier that is mapped to the RACH preamble.
