Abstract: Disclosed herein is a method at a User Equipment (UE) comprising determining that a current radio resource configuration is of a normal type, and responsive to the determining, prohibiting the UE from sending a Power Preference Indication (PPI) for a radio resource configuration of the normal type. Also disclosed is a method at a UE comprising: determining that a current radio resource configuration is of a power optimized type, and responsive to the determining, prohibiting the UE from sending a PPI for a radio resource configuration of the power optimized type. Also disclosed is a UE including a processor, the UE configured to: determine that a current radio resource configuration is of a normal type, and responsive to the determining, refrain from sending a PPI for a radio resource configuration of the normal type.

Abstract: A wireless access network node receives assistance information from a user equipment (UE) or other wireless access network node, the assistance information comprising information indicating one or more channels of an unlicensed spectrum to use or avoid. Responsive to the assistance information, the wireless access network node selects at least a first channel of the unlicensed spectrum for communicating data of the UE.

Abstract: A method for allocating resources for device-to-device transmission between two or more user equipment (UEs) includes transmitting, from a first UE to a second UE, a resource allocation configuration for device-to-device communications. A resource request for a device-to-device transmission is received from the second UE. In response to the resource request, a resource for the device-to-device transmission is selected at the first UE. A resource grant is transmitted to the second UE. The resource grant identifies the selected resource. A device-to-device transmission is received from the second UE over the selected resource.

Abstract: In some implementations, a Medium Access Control (MAC) method for LTE in Unlicensed (LTE-U) includes transmitting at least one of a Clear to Send (CTS) message or a Request to Send (RTS) message on an LTE-U Secondary Cell (SCell) carrier. The at least one of the CTS message or the RTS message may include a duration field. The duration field may indicate a transmission time of a transmission on a packet data shared channel on the LTE-U SCell carrier. An evolved NodeB (eNB) transmits a scheduling grant for the transmission on the packet data shared channel on the LTE-U SCell carrier.

Abstract translation: 在一些实施方式中，用于LTE的未授权（LTE-U）的媒体接入控制（MAC）方法包括：在LTE-U次要信道上发送清除发送（CTS）消息或请求发送（RTS）消息中的至少一个 细胞（SCell）载体。 CTS消息或RTS消息中的至少一个可以包括持续时间字段。 持续时间字段可以指示在LTE-U SCell载波上的分组数据共享信道上的传输的传输时间。 演进节点B（eNB）在LTE-U SCell载波上的分组数据共享信道上发送用于传输的调度许可。

Abstract: Systems and methods to configure sidelink resources in a dual connectivity operation are provided. In some aspect, a method comprising: transmitting, from a user equipment (UE), a first message to a first evolved Node B (eNB), wherein the first message indicates a request to establish a sidelink communication; receiving, at the UE, a second message from the first eNB, wherein the second message indicates a frequency that is used by a secondary evolved Node B (SeNB); transmitting, from the UE, a measurement result to the first eNB; and receiving, at the UE, sidelink configuration information from the first eNB, wherein the sidelink configuration information indicates sidelink resources managed by the secondary eNB.

Abstract: A method for transmitting a scheduling request includes receiving, at a relay UE and from a remote UE, a sidelink control information. The relay UE is within a coverage area of a base station. The remote UE is outside of the coverage area. The relay UE is configured to relay transmissions from the remote UE to the base station, and the sidelink control information indicates a future transmission of a data packet over a sidelink channel. A scheduling request is transmitted to a base station. A scheduling grant that indicates an uplink resource is received from the base station. A data packet over the sidelink channel is received from the remote UE.

Abstract: In some examples, by a first network node of a first network sends, in response to a request from a user equipment (UE) served by a second network, scheduling information to a second network node of the second network, the scheduling information granting a resource for use by the UE for a direct wireless transmission between the UE and a wireless device, where the first network is different from the second network, and where the sending of the scheduling information to the second network node of the second network is to cause the second network node of the second network to send the scheduling information to the UE.
