Method and device for signal transmission or reception on basis of LTE and NR in wireless communication system

The present invention relates to a method for signal transmission or reception by a terminal dual-connected to a first radio access technology (RAT) or a second RAT in a wireless communication system. Specifically, the method comprises: a step of receiving a first RAT-based downlink reference time domain duplex (TDD) uplink-downlink configuration; and a time division multiplexing (TDM) step of, when an uplink subframe on the basis of the downlink reference TDD uplink-downlink configuration is associated with a first transmission time unit having a predetermined length, setting the first transmission time unit for the first RAT and setting a second transmission time unit for the second RAT. The second transmission time unit is obtained by excluding a transmission time unit from the uplink subframe. The terminal is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

SYSTEMS AND METHODS FOR PLANNING AND OPERATING RADIOS CONTROLLED BY A SPECTRUM ACCESS SYSTEM

Techniques are provided for planning frequency spectrum and power allocated to transmission points of a radio network that is controlled by a spectrum access system and shares spectrum with incumbents and/or other secondary users (e.g., external radio(s)). Techniques are also provided for managing communications between components of the radio network and the spectrum access system, and to allocate frequency spectrum and maximum transmission power to component(s) of a radio network.

BACKWARD COMPATIBLE FRAME REUSE BY USING PREDETERMINED MASKING SEQUENCE
20170332241 · 2017-11-16 ·

A backward compatible frame reuse mechanism that allows new information to be defined a reused frame without causing any incorrect operation in a legacy receive device. To generate a reused frame, a portion of the frame in the first format is masked with a predetermined masking sequence (PMS) and thereby redefined as new fields in a second format. When a device that supports the reuse scheme receives a frame that possible is a reused frame, the device checks the potentially reused portion according to the first format after de-masking and also checks according to the second format without de-masking. Based on the check results, the device selects a format to resolve the frame. A legacy device receiving the reused frame only checks the reused portion without de-masking, which results in a certain check error and makes the device discard the frame without any harmful operation.

Method and apparatus for timeslot swapping

All or a portion of a timeslot of a slotted communication system may be dynamically designated for transmitting or for receiving. For example, a timeslot originally designated for receiving information at a wireless node may be temporarily designated for transmitting information from the wireless node. Such a designation may be made to accommodate a temporary asymmetry in traffic flow between wireless nodes or may be made based on other criteria. In some aspects, a resource utilization messaging scheme may be employed to mitigate interference associated with the designation of timeslots for transmitting or receiving.

Parameter scaling for fractional bandwidth systems

Methods, systems, and devices are described for making scaling adjustments with respect to a fractional subsystem in a wireless communications system. To handle the effects of scaling associated with fractional bandwidth systems, different adjustments may be made to maintain certain quality of service (QoS) requirements, for example. Scaling adjustments may include identifying a scaling factor for the fractional subsystem and a parameter and/or a timer associated with the fractional subsystem. An adjustment associated with the parameter and/or timer may be determined based on the scaling factor. The adjustment may be applied with respect to the parameter and/or timer for at least a portion of the fractional subsystem or another portion of the wireless communications system.

Dynamic resource management

An access node may monitor for uplink and downlink resource release indications signaled by a parent access node and a child access node prior to scheduling a released resource. In some cases (e.g., when the child node is capable of half-duplex communications), the parent access node may determine to release a resource, and the child access node may determine to release a hard resource (e.g., a child node controlled resource). Receiving uplink and downlink resource release indications may enable the access node to schedule communication with the child node via a soft resource (e.g., a parent node controlled resource). Other aspects of the described techniques are directed to feedback support for a slot format indicator (SFI). The feedback from the access node may accept or reject the SFI based on an impact the SFI has on scheduling via a child link established with a child node of the access node.

A method for controlling Long Range Wide Area Network (LoRa) apparatus includes: selecting a first transceiver and a second transceiver among a plurality of transceivers, assigning a first set of frequency bands to the first transceiver, assigning a second set of frequency bands, different from the first set of frequency bands, to the second transceiver, setting the first transceiver so that the first transceiver embeds a first flag in a first request when sending the first request to a mother node and setting the second transceiver so that the second transceiver embeds the first flag in the first request when sending the first request to the mother node.

During handover of a radio terminal (1) from a first network to a second network, a target RAN node (3) is operates to: receive, from a core network (5), slice information about a network slice which is included in the second network and to which the radio terminal (1) is to be connected; create, upon receiving the slice information, radio resource configuration information that is to be used by the radio terminal (1) after the handover in the second network; and transmit this radio resource configuration information through the first network to the radio terminal (1). It is possible to contribute to appropriately configuring an AS layer or NAS layer of a target RAT in inter-RAT handover.
