Methods and systems for providing an enhanced proximity services. The method includes monitoring, by a proximity controller provisioned in a preferred network, dual subscriber identification module (SIM) dual subscriber (DSDS) devices operating in the preferred network, detecting, by the proximity controller, a DSDS device operating in a non-preferred network, wherein the DSDS devices and the DSDS device are configured to switchably operate in one of the preferred network or the non-preferred network based on coverage, locating, by the proximity controller, from the monitored DSDS devices a DSDS device proximate to the DSDS device operating in the non-preferred network, and enabling, by the proximity controller, the proximate DSDS device and the DSDS device operating in the non-preferred network to establish a sidelink communication channel between the proximate DSDS device and the DSDS device operating in the non-preferred network for offloading data communications from the non-preferred network to the preferred network.

An embodiment provides an operation method of a sidelink reception terminal in a wireless communication system, the method comprising the steps of: receiving a first physical sidelink shared channel (PSSCH) and a second PSSCH by a sidelink reception terminal; and transmitting feedbacks for the first PSSCH and the second PSSCH through a first physical sidelink feedback channel (PSFCH) resource and a second PSFCH resource, respectively, by the sidelink reception terminal, wherein the first PSSCH and the second PSSCH are received in different slots, and a first PSFCH related to the first PSSCH and a second PSFCH related to the second PSSCH are transmitted through different frequency resources within an identical time resource area.

Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-of-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-of-COT resources. The UE may then transmit to a second UE using the set of transmission resources.

A system, method and apparatus for wireless communications is provided. A user equipment (UE) receives, from a first base station, one or more first messages that include measurement configuration parameters and sidelink parameters associated with a first cell. The UE establishes a sidelink with a second UE based on the sidelink parameters and transmits, to the first base station, a measurement report based on the measurement configuration parameters. Responsive to the measurement report, the UE receives a second message comprising second configuration parameters of a second cell of a second base station. The second configuration parameters do not comprise sidelink parameters. The UE then switches from the first cell of the first base station to the second cell of the second base station. The sidelink of the first cell is handed over to an uplink of the second cell.

Aspects of the disclosure provide a method for a first user equipment (UE) that has a first path to a network to add a second path to the network. For example, the method can include receiving, at the first UE, a first radio resource control (RRC) message from the network for addition of the second path. The method can also include configuring, by the first UE, the second path based on the first RRC message.

Methods, systems, and devices for wireless communications are described in which two or more UEs of a wireless communications system may establish a sidelink connection. A first UE that is initiating sidelink communications may evaluate whether the sidelink connection can support a quality of service (QoS) for a data flow prior to admitting the data flow. The first UE may evaluate a link quality with one or more other UEs that are to use the data flow on the sidelink connection, evaluate system congestion of time/frequency resources that are available for the sidelink connection, or any combinations thereof, and admit the data flow based on the evaluation. A link quality of the sidelink connection may be determined based on a type of communication associated with the data flow, such as unicast communications with one other UE, multicast communications with multiple other UEs, or broadcast transmissions to multiple UEs.

Provided are a method for a terminal stopping information transmission in a wireless communication system, and a device supporting same. The method may comprise the steps of: receiving first power control information for setting a transmission power to zero; and stopping information transmission on a resource on the basis of the first power control information.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a sidelink buffer status reporting in a D2D communication system, the method comprising: configuring a first ProSe destination including at least one first UE and a second ProSe destination including at least one second UE; receiving a first sidelink data for a first sidelink logical channel from an upper layer; receiving a second sidelink data for a second sidelink logical channel from the upper layer while the UE has the first sidelink data for the first logical channel, wherein the second logical channel has a higher priority than a priority of the first sidelink logical channel; and triggering a buffer status reporting the if the first sidelink logical channel and the second sidelink logical channel belong to a same ProSe destination.

Provided are a method for performing wireless communication by a first device and an apparatus supporting same. The method may comprise the steps of: transmitting, to a second device, information related to a first resource on a sidelink (SL) bandwidth part (BWP); and performing SL reception from the second device on a second resource on the SL BWP. The second resource may not overlap with the first resource.

A system, method and apparatus for wireless communications is provided. A user equipment (UE) receives, from a first base station, one or more first messages that include measurement configuration parameters and sidelink parameters associated with a first cell. The UE establishes a sidelink with a second UE based on the sidelink parameters and transmits, to the first base station, a measurement report based on the measurement configuration parameters. Responsive to the measurement report, the UE receives a second message comprising second configuration parameters of a second cell of a second base station. The second configuration parameters do not comprise sidelink parameters. The UE then switches from the first cell of the first base station to the second cell of the second base station. The sidelink of the first cell is handed over to an uplink of the second cell.
