Abstract: A device, serving cell and method of switching between modes of operation for the device in a cellular network comprises receiving a service via a connection with the serving cell. A condition indicative of deterioration in network service and an absence of a suitable neighbor cell are detected. In response, discovery of relay nodes is initiated. When a suitable relay node is discovered, a mechanism to switch to receiving the service via the suitable relay node is initiated. The service may be a mission critical push-to-talk over Long Term Evolution service. The relay node may be user equipment acting as a user equipment-to-network relay node. When the device is in an RCC_CONNECTED state, the mechanism to switch includes sending a relay mode preference indication to the serving cell, receiving a connection release message from the serving cell, releasing the serving cell connection, and establishing a sidelink connection with the relay.

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: Example base stations and methods for receiving transmissions on an enhanced random access channel (RACH) are disclosed herein. An example method for receiving transmissions on an enhanced RACH from a device such that an initial access burst is received in a single time slot from the device involves receiving the initial access burst from the device on the enhanced RACH. The initial access burst is sent by the device using a timing advance determined at the device. The initial access burst includes at least one of an identifier or user data. The enhanced RACH is a contention-based uplink-only channel requiring use of timing advances for transmissions thereon.

Abstract: Methods and apparatus to report link quality measurements for downlink dual carrier operation are disclosed. Example methods and apparatus disclosed herein implement one or more example techniques for reporting link quality measurements involving, for example, modifying measurement reporting messages to increase the number and/or types of link quality measurements that can be reported, permitting mobile stations, when appropriate, to use different reporting messages capable of supporting more link quality measurements, and/or prioritizing certain link quality measurements to be reported when the reporting messages do not contain sufficient space to report all requested and/or specified link quality measurements.

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.
