Systems and methods presented herein provide for reducing latency in wireless service through a communication link comprising a Modem Termination System (MTS) and a modem. The communication link is coupled with a virtualized wireless link. In one embodiment, a method includes transferring a buffer status report (BSR) from a user equipment (UE) through the communication link to a control portion of the virtualized wireless link, generating a wireless grant to allow the data of the UE through virtualized wireless link, and generating a backhaul grant for the UE to transfer data through the communication link based on the wireless grant information.

The disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for the Internet of things (IoT). The present disclosure may be applied to intelligent services based on 5G communication technology and IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure provides a method and apparatus for handling message A retransmission during 2 step random access procedures.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay device may receive, from a first user equipment (UE) on a sidelink channel, a buffer status report. Accordingly, the relay device may receive, from a base station, a grant of an uplink resource based at least in part on determining a priority of data associated with the buffer status report. Additionally, the relay device may transmit, to the base station, the buffer status report based at least in part on receiving the grant of the uplink resource. Numerous other aspects are provided.

This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method of wireless communication performed by a user equipment (UE) includes receiving, from a base station, a grant message indicating a set of sidelink resources. The method further includes transmitting multiple unicast messages via multiple subgroups of the set of sidelink resources.

A method performed by a user device having a multiple connectivity configuration with a plurality of radio links to a plurality of network nodes in a radio communication network is provided. The user device can determine a change occurred in an amount of uplink data available for transmission in a first uplink buffer of the user device on a first radio link of a plurality of radio link to first network node. Responsive to the change, the user device can trigger a buffer status report for transmission to a second network node of the plurality of network nodes on a second radio link of the plurality of radio links for which a change in an amount of uplink data available for transmission in a second uplink buffer was not determined. A method performed by the first network node is also provided.

Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.

A method and an apparatus for beam failure recovery in a communication system. The method for beam failure recovery includes the steps of: searching for a plurality of candidate beams when a beam failure is detected; transmitting a beam failure recovery request signal to a base station by using beam #1 of the plurality of candidate beams; receiving a beam failure recovery response signal in response to the beam failure recovery request signal via beam #1 from the base station; and transmitting an SR requesting a resource for transmission of multi-beam setting information to the base station, where the multi-beam setting information includes indexes of one or more beams excluding beam #1 of the plurality of candidate beams.

A method and device are disclosed from the perspective of a first device handling radio link failure. In one method, the method includes the first device performing or establishing sidelink unicast communication with a second device. The method also includes the first device performing or establishing sidelink unicast communication with a third device. The method also includes the first device detecting a radio link failure associated with the second device. The method further includes the first device performing a Sidelink MAC reset associated with the second device in response to the radio link failure, and not performing a Sidelink MAC reset associated with the third device.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink data associated with a first quality of service flow is available for transmission to a base station. The UE may transmit a buffer status report to the base station. In some examples, the buffer status report may include a buffer status of the first quality of service flow. The UE may then receive an uplink grant based on transmitting the buffer status report, and may transmit the uplink data based on the uplink grant.

The present application relates to user equipment (UE) assisted uplink resource modification. In one implementation, a UE may determine an upcoming absence of uplink data for transmission on an uplink communication channel to a network entity during a period defined by a configured grant, and transmit a message to the network entity to trigger adjustment of at least one resource associated with the configured grant. In another implementation, a network entity may receive a message from a UE representing an upcoming absence of uplink data on an uplink communication channel during a scheduled period defined by a configured grant, and adjust at least one resource associated with the configured grant in response to receiving the message
