Abstract: Geo-fenced bandwidth switching for Reduced Capability NR devices is provided. An apparatus may include at least one processor, and at least one memory storing instructions. The stored instructions, when executed by the processor, cause the terminal device at least to receive, from a network element, information comprising a plurality of characteristics of one or more precision zones configured for the terminal device. The apparatus is further caused at least to apply a precision zone selected from the one or more precision zones in accordance with a current location of the terminal device in communication of a reference signal for positioning of the terminal device.

Abstract: Embodiments of the present disclosure relate to UL-based and DL-based positioning in a wireless communication network. A method comprises: determining, by a first device, an estimation of a propagation delay for a first reference signal to be transmitted from a second device; in accordance with a determination that the estimation of the propagation delay exceeds a threshold delay, determining a target period within a symbol on which at least a part of the first reference signal is transmitted; and performing positioning measurements on the first reference signal within the target period. As such, the receiver is capable of applying an adaptive and adjustable window for receiving different positioning reference signals (PRSs) depending on various conditions and situations. In this way, the PRS measurement performance and the positioning accuracy can be greatly improved.

Abstract: A method for a base station includes sending a request for a report on beamforming capability to a target user equipment; receiving the report on the beamforming capability from the target user equipment; allocating at least one positioning reference signal resource for use by the target user equipment based on at least the capability information included in the report; determining a beam sweeping mle based on the at least one positioning reference signal resource allocated for the target user equipment; and sending the positioning reference signal resource allocation and the beam sweeping mle to the target user equipment. A corresponding method for a user equipment includes receiving a request for a report on beamforming capability from a serving base station; sending the report on the beamforming capability to the serving base station; receiving information relating to at least one positioning reference signal resource and a beam sweeping rule from the serving base station; and performing beam sweeping on uplink positioning reference signal transmissions using the received positioning reference signal resource allocation based on the beam sweeping rule.

Abstract: Systems, methods, apparatuses, and computer program products for using angle error groups (AEGs) to improve angle of arrival (AoA) positioning may be provided. For example, for a specific received signal, one or more receiving antenna elements that can be considered to have almost the same incident angle within a certain margin may be defined as a group. The group of receive (Rx) antenna elements (or a group of Rx antennas) may be defined as an AEG. The configuration of an AEG for each TRP and the AEG may be used for AoA measurement and reporting. The gNB or transmit receive point (TRP) may perform AoA measurements and may determine an AoA for the AEGs.

Abstract: According to an example embodiment, a method may include receiving, by a user equipment from a base station associated with a cell, control information assigning a subframe as a preconfigured uplink resource (PUR) subframe for the user equipment, the preconfigured uplink resource (PUR) subframe including an extended cyclic prefix, the control information indicating resources allocated to the user equipment for uplink transmission within the preconfigured uplink resource (PUR) subframe, wherein one or more other subframes for use by the user equipment include a normal cyclic prefix that is shorter in time than the extended cyclic prefix of the preconfigured uplink resource (PUR) subframe; and transmitting, by the user equipment, data via the resources allocated to the user equipment within the preconfigured uplink resource (PUR) subframe.

Abstract: An uplink non-orthogonal multiple access for narrowband machine type communication used for the deployment of Internet of Things (IoT) interconnected devices where one or more user equipment are configured for uplink transmission with one or more uplink time-frequency regions for enhanced Machine Type Communication Non-Orthogonal Multiple Access. The configuring is based on defining and signaling one or more signal thresholds and one or more of a resource assignment, a starting subframe periodicity, a starting subframe offset, a time duration in each period, a demodulation reference signal cyclic shift assignment, orthogonal cover code assignment, and interleaver assignment.
