The present invention discloses method for transmitting downlink packet in function-separated core network. It is an object of the embodiments of the present disclosure to provide a method for transmitting a downlink packet for a UE in an idle mode which is capable of reducing a data transmission latency for a user and efficiently using network resources in a mobile communication system in which the control plane and the user plane of a gateway node are separated.

A communication control method includes receiving, by a relay user equipment, data transmitted from a remote user equipment on a sidelink, transmitting, from the relay user equipment to a base station and on an uplink, the data received from the remote user equipment, and transmitting, from the relay user equipment to the remote user equipment, restriction information restricting an amount of data to be transmitted by the remote user equipment.

Embodiments of apparatus and method for uplink grant handling are disclosed. In one example, a method for uplink grant handling can include receiving an uplink grant at a user equipment from a network device. The method can also include associating the uplink grant directly with a logical channel group including a plurality of logical channels. The user equipment can be configured to dequeue the logical channel group directly with priority for transmission scheduling. In some embodiments, the method can further include sending, to the network device from the user equipment, a request to associate a list of logical channel groups including the logical channel group. The request to associate can include a request to associate the plurality of logical channels with the logical channel group.

A user equipment (UE) configured to receive an uplink (UL) grant comprising a UL grant size, determine a current UL buffer size, compare the current UL buffer size to the UL grant size and determining an amount of padding to fill the UL grant and determine whether to transmit on the UL grant based on the amount of padding to fill the UL grant.

Methods, systems, and devices for wireless communications are described for radio frequency (RF) exposure limit compliance using uplink duty cycling. A user equipment (UE) may transmit a buffer status report (BSR) that indicates an amount of data that is to be transmitted by the UE, where lower priority data reported in the BSR may be throttled in order to reduce an amount of uplink resources associated with the lower priority data and thereby adjust an uplink duty cycle of the UE. The reduced uplink duty cycle may provide for additional transmit power that is available for higher priority data transmissions.

Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises circuitry to configure a scheduling request (SR) transmission based on a physical uplink control channel (PUCCH), and combine the scheduling request with a buffer status report (BSR). The UE transmits the combined SR and BSR in a single subframe to a network entity, receives uplink resource scheduling from the network entity in reply to the combined SR and BSR, and transmits uplink data to the network entity according to the uplink resource scheduling.

Systems, apparatuses and methods may provide for technology that adjusts, via a short-term subsystem, a communications parameter for one or more of wireless communication devices based on data from one or more of a plurality of sensors. The technology may also determine, via a neural network, a prediction of future performance of the wireless network based on a state of the network environment, wherein the state of the network environment includes information from the short-term subsystem and location information about the wireless communication devices and other objects in the environment, and determine a change in network configuration to improve a quality of communications in the wireless network based on the prediction of future performance of the wireless network. The technology may further generate generic path loss models based on time-stamped RSSI maps and record a sequence of events that cause a significant drop in RSSI to determine a change in network configuration.

Embodiments of a multi-link device (MLD) are generally described herein. The MLD may be configured for multi-link communication on a plurality of links. The MLD may be configured with a plurality of stations (STAs). Each STA may be a logical entity that includes a singly addressable instance of a medium access control (MAC) layer and a physical (PHY) layer of a link of the plurality of links. The MLD may configure traffic identifier (TID) assignment for the MLD for multi-link communication with another MLD. The multi-link communication may be configurable to support one or more data streams, wherein each of the data streams corresponds to a TID. The MLD may determine an assignment of the TIDs to the STAs of the MLD.

A base station central unit receives, from a base station distributed unit, assistance information indicating whether subsequent data is expected for a small data transmission (SDT) procedure of a wireless device. The base station central unit transmits a radio resource control (RRC) release message to the wireless device based on the assistance information.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit, to a base station, a sidelink scheduling request for groupcast sidelink communications with a set of one or more UEs. The base station may determine one or more UEs of the set of UEs and time-frequency resources for groupcast sidelink communication between the first UE and the one or more UEs. The first UE may receive, from the base station, a groupcast sidelink grant that indicates time-frequency resources for groupcast sidelink communications between the first UE and one or more UEs. The first UE may transmit, via the time-frequency resources indicated by the groupcast sidelink grant, a groupcast sidelink message to the one or more UEs. The one or more UEs may also receive the sidelink grant, and may monitor the time-frequency resources for a groupcast sidelink communication from the first UE.
