摘要： Systems and methods relating to a transmission timing difference between cells in a multi-carrier system in which at least one of the cells is subject to Clear Channel Assessment (CCA) before transmitting are disclosed. In some embodiments, a method of operation of a User Equipment (UE) comprises determining a transmission timing difference between a first cell that operates on a first carrier and a second cell that operates on a second carrier, wherein CCA is required to be performed on at least one of a first channel in which the first carrier is located and a second channel in which the second carrier is located before the UE is permitted to transmit. The method further comprises using the transmission timing difference for one or more operational tasks of the UE. The transmission timing difference is determined when the first channel and the second channel are available at the UE.

摘要： A method for adaptive radio link monitoring RLM) includes a network node obtaining configuration information about a user equipment (UE) receiver configuration associated with a UE, where the UE receiver configuration is implemented by the UE for receiving signals from the network node. The method further includes the network node adapting, based on the obtained configuration information, at least one radio transmission parameter associated with at least one downlink (DL) signal used by the UE for performing the RLM. The method also includes the network node transmitting the at least one DL signal with the adapted at least one parameter to the UE enabling the UE to perform the RLM.

摘要： A method in a node is disclosed. The node receives one or more radio signals. The node determines a first measurement component of the one or more radio signals. The first measurement component is associated with a first time-frequency resource type. The node determines a second measurement component of the one or more radio signals. The second measurement component is associated with a second time-frequency resource type. The node determines a relative measurement for the first measurement component associated with the first time-frequency resource type and the second measurement component associated with the second time-frequency resource type. The relative measurement may be a function of the first measurement component associated with the first time-frequency resource type and the second measurement component associated with the second time-frequency resource type. The node performs one or more radio operations using the relative measurement.

摘要： A node of a multiple radio access technology (multi-RAT) system acquires resource status information associated with each RAT of the multi-RAT system. The resource status information of the RATs of the multi-RAT system can be acquired by sniffing higher layer protocol information pertaining to call setup requests and/or call terminated messages. The node further maintains a flag representing overall resource availability associated with the RATs of the multi-RAT system, based on the acquired resource status information, for use in admission control and/or load balancing. The flag is associated with a pre-defined set of overall resource availability states of the multi-RAT system, where the availability states are defined in terms of admission control decisions.

摘要： Systems and methods are disclosed for utilizing non-overlapping time periods within one or more Discontinuous Reception (DRX) cycles configured for a Device-to-Device (D2D) capable wireless device for different types of operations. In some embodiments, these different types of operations are cellular and D2D operations such that the D2D capable wireless device performs cellular and D2D operations (e.g., reception of cellular and D2D signals) during non-overlapping time periods during one or more DRX cycles. In this manner, a D2D capable wireless device that, for example, can only receive one type of signal at a time is enabled to receive both cellular and D2D signals.

摘要： A method in a user equipment comprises receiving, from a network node, a request to configure a first component carrier at the user equipment for dual connectivity operation, and determining whether a total number of currently configured component carriers including the first component carrier associated with the request exceeds a threshold number of component carriers that the user equipment can use for dual connectivity operation. The method further comprises performing one or more component carrier related radio operations based at least in part on the determination of whether the total number of currently configured component carriers including the first component carrier associated with the request exceeds the threshold number of component carriers that the user equipment can use for dual connectivity operation.

摘要： A network node (310) comprising a radio frequency communications interface (230) and a controller (210), said network node (310) being configured to service at least one first radio frequency communication device (320) being configured for both network communication and for device-to-device communication with a second radio frequency communication device (325), wherein said controller (210) is configured to determine if a restriction of a scheduling policy is necessary for said first radio frequency communication device (320), select a scheduling policy accordingly. The controller is further configured to allocate communication resources according to said selected scheduling policy to said first radio frequency communication device (320). The scheduling policy is one which enables simultaneous network communication and device-to-device communication in said same transmission time interval (A, B, C, D, E) or one which enables either network communication or device-to-device communication in said same transmission time interval.

摘要： Techniques and devices for improving uplink positioning techniques are described. An example method, implemented in a first node in a wireless communications network, begins with obtaining multi-antenna configuration information or multi-antenna capability data, or both, for a second node in the wireless communications network. The node carrying out the node may be a radio base station, a measuring node, or a wireless device to be positioned, in various embodiments. In some embodiments, the second node is a measuring node. In others, the second node is the wireless device to be positioned. The method continues with adapting a multi-antenna configuration of the wireless device for one or more transmissions to be measured for positioning purposes, or adapting a multi-antenna configuration of the measuring node for one or more positioning measurements, or both. The adapting is based on the obtained multi-antenna configuration information or multi-antenna capability data, or both.
