  • Patent number: 12349065
    Abstract: A wireless device receives parameters, including a first discontinuous reception (DRX) configuration associated with unicast transmissions in a cell and a second DRX configuration associated with multicast and broadcast services (MBS) in the cell. The wireless device may also receive a power saving (PS) indication indicating not to start a DRX on duration timer. The PS indication may be applied for the first DRX configuration; and it may not be applied for the second DRX configuration. The wireless device may further skip monitoring, in a first DRX on duration of the first DRX configuration, first physical downlink control channels (PDCCHs) for the unicast transmissions based on receiving the PS indication. The wireless device may also monitor, in a second DRX on duration of the second DRX configuration and while skipping monitoring the first PDCCHs in the first DRX on duration, second PDCCHs for the MBS.

  • Patent number: 12342335
    Abstract: A first wireless device receives, from a base station, configuration parameters of a scheduling request for a sidelink buffer status report (BSR) of a sidelink between the first wireless device and a second wireless device. The scheduling request is triggered for the sidelink BSR in response to data becoming available for transmission to the second wireless device via the sidelink. The first wireless transmits, based on the triggering and to the base station, a preamble for a random access procedure to obtain a first uplink grant to transmit the sidelink B SR. The sidelink BSR is transmitted via a second uplink grant different from the first uplink grant indicated in a random access response corresponding to the preamble. The random access procedure is stopped in response to transmitting the sidelink BSR.

  • Publication number: 20250203675
    Abstract: Various methods and systems of the present disclosure provide a protocol data unit (PDU) set based quality of service (QoS) handling in a wireline access. To support the PDU Set based QoS handling in the wireline access, one or more PDU Set QoS parameters and/or PDU Set information may be provided to one or more wireline nodes (e.g., a wireline gateway access function (W-AGF) and/or a residential gateway (RG) etc.). When the W-AGF receives one or more N2 requests associated with one or more PDU session resources, the W-AGF maps one or more QoS profiles received from 5G core (5GC) to a wireline access user plane (W-UP) QoS level. The W-AGF sets up one or more W-UP resources based on the W-UP QoS level for a PDU session. Further, various methods and systems of the present disclosure also provide low latency, low loss, and scalable throughput (L4S) enabled wireline access.

  • Patent number: 12335967
    Abstract: A small data transmission (SDT) procedure may be used for data transmission in certain scenarios. The SDT procedure may be terminated based on certain conditions to enable efficient resource utilization. For example, the SDT procedure may be terminated if a wireless device does not have any additional data for transmission. To enable termination of the SDT procedure in such a scenario, a message may be used to indicate (e.g., to a base station) that no additional data is available for transmission.

  • Publication number: 20250193847
    Abstract: A first wireless device selects first radio resources for a first sidelink transmission of the first wireless device. The first wireless device receives, from a second wireless device, sidelink control information (SCI) reserving second radio resources for a second sidelink transmission of the second wireless device. The first wireless device determines a collision between the first radio resources and the second radio resources. The first wireless device performs a comparison of a first priority of the first sidelink transmission and a second priority of the second sidelink transmission. The first wireless device selects, based on the comparison and the collision, third radio resources for the first sidelink transmission. The first wireless device transmits the first sidelink transmission via the third radio resources.
