Operating method at dormant BWP in wireless communication system and terminal using same method

The present specification relates to a method for receiving dormant bandwidth part (BWP) configuration information, performed by a terminal in a wireless communication system, the method comprising: receiving the dormant BWP configuration information from a base station, wherein the dormant BWP configuration information is information about a downlink BWP used as the dormant BWP among at least one downlink BWP set to the terminal; receiving, from the base station, downlink control information (DCI) notifying activation of the dormant BWP; and stopping monitoring of a physical downlink control channel (PDCCH) on the dormant BWP, wherein a BWP inactivity timer is not used on the basis of the activation of the dormant BWP, and the BWP inactivity timer is a timer for a transition to a default BWP.

Downlink control information signaling schemes for bandwidth part switching

Different sets of downlink control information (DCI) fields may be configured for DCI that includes an indication to trigger bandwidth part switching at a user equipment (UE). For example, a UE may receive DCI that triggers the UE to switch operation from a first bandwidth part to a second bandwidth part. The UE may also identify a set of transformable DCI fields and a set of non-transformable DCI fields within the DCI. The UE may then determine updated content of the DCI for application to the second bandwidth part based on whether DCI fields are included in the set of transformable or the set of non-transformable fields. In some cases, the UE may identify a null assignment in the received DCI and may switch its operation from the first bandwidth part to the second bandwidth part based on the null assignment.

Time duration of a delay between receiving a downlink data packet and user plane connection activation

A session management function (SMF) sends, to an access and mobility management function (AMF), one or more first messages indicating user plane connection activations for a plurality of packet data unit (PDU) sessions to deliver downlink user data to one or more wireless devices. The SMF receives, from the AMF, a first time duration based on the user plane connection activations for the plurality of PDU sessions. The first time duration indicates a delay between receiving a downlink data packet and notifying the AMF about user plane connection activation for the downlink data packet. The SMF sends, to a user plane function, a second message to delay sending of further user plane connection activations to the SMF. The second message indicates a value of the first time duration.

User equipment indication for adaptive scheduling restrictions

Improved techniques of managing measurement gaps for MPUEs include identifying an idle time for the UE in a coordinated and network-controlled manner during which the UE is able to perform SSB/CSI-RS based measurements for a serving cell using non-serving panels. Such idle time is defined as an omitted operation time (i.e., an idle time of a certain pre-defined length) in which the network has to apply the scheduling restrictions in the SSBs' symbols to the UE. Note that currently as per the RAN4 requirements, the network must apply scheduling restrictions in all SSB symbols for all UEs in FR2 at any time (i.e., worst case scenario).

Techniques for selecting RSMA spreading code for periodic traffic in internet-of-everything devices
11582717 · 2023-02-14 · ·

Aspects of the present disclosure provide techniques to reduce overhead and improve resource management by efficiently selecting RSMA spreading code for periodic traffic in IoE devices. For example, in accordance with one technique, the IoE device, during an initial access to the base station, may notify the base station of the traffic periodicity of the IoE device such that the base station may assign a spreading code from a dedicated pool that is not utilized during the periodic access of the device. Additionally or alternatively, another technique to reduce overhead and improve resource management may include the IoE devices broadcasting the selected RSMA spreading code that the IoE devices intends to use in discovery broadcasts (DBs) along with the IoE device traffic periodicity such that the IoE devices may autonomously manage selection of RSMA spreading code that avoids collisions for the same traffic periodicity.
