摘要： Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

摘要： Embodiments herein relate to a transmitting node and method therein for transmitting channel information in subframes to a receiving node. Each subframe comprises a number of control channel elements and a set of control channel candidates. The transmitting node transmits control channel information in a subframe when a start control channel element index of a control channel candidate is smaller than or equal to the number of available control channel elements in a predefined subframe, and refrains from transmitting control channel information when the start control channel element index of the control channel candidate is larger than the number of available control channel elements in the predefined subframe. The embodiments also relate to a receiving node and method therein.

摘要： Systems and methods relating to transmission and reception of a Random Access Response (RAR) message to a wireless device (e.g., a User Equipment (UE)) in a manner that is particularly well-suited for, but not limited to, reduced bandwidth devices, such as Machine Type Communication (MTC) devices, are disclosed. In some embodiments, a method of operation of a wireless device to perform random access to a cellular communications network comprises transmitting a random access preamble on a physical random access channel and determining, from a random access preamble index of the random access preamble, one of a random access response resource and a channel to monitor for a transmission of an indication of the random access response resource. The method further comprises receiving a random access response on the random access response resource.

摘要： Systems and methods related to a synchronization signal particularly well suited for wireless devices in an extended coverage area of a cell of a cellular communications network are disclosed. In one embodiment, a base station transmits a synchronization signal including multiple repetitions of a basic synchronization block during a coherence time of a downlink channel over which the synchronization signal is transmitted. The multiple repetitions of the basic synchronization block during the coherence time enable coherent combining during detection of the synchronization signal at wireless devices located in the cellular communications network. This coherent combining enables, for example, wireless devices located in an extended coverage area of a cell served by the base station to synchronize to the cell using a shorter synchronization signal than that which would be required if only non-coherent combining were used.

摘要： A radio network node (12) communicates with user equipments, UEs, (10) over a radio interface and estimates one or more quality factors, associated with each of a first and second network, that depend on a load or an expected UE behavior or an uplink channel quality for one or both of first and second networks. The node (12) determines one or more network selection parameters based on the estimated one or more quality factors, and communicates the one or more network selection parameters to at least one UE (10) for enabling the UE to select one of the first and second networks for subsequent access by the at least one UE. The UE receives from the radio network node one or more network selection parameters. The UE uses the one or more network selection parameters to select one of first and second radio networks and then accesses the selected radio network.

摘要： A Level-1 (L1) signaling flag is mapped to unused (invalid) bit sequences in Part 1 of the HS-SCCH—that is, Part 1 bit encodings that are not defined in the UTRAN specifications—and a corresponding L1 command is encoded in Part 2. This allows UE (18) to detect early that the HS-SCCH is pure L1 signaling, and the UE (18) may avoid wasting power by not processing an accompanying HS-PDSCH. Alternatively, in CPC HS-SCCH-less mode, the UE (18) may blind decode the HS PDSCH. In one embodiment, a general DRX mode is defined and controlled via L1 signaling. In one embodiment, a UE (18) acknowledgement improves the L1 signaling accuracy. In one embodiment, a L1 signal and UE (18) acknowledgement protocol are utilized to “ping” a UE (18).

摘要： A user equipment transmits using at least two uplink transmit antennas and receives a set of control signals in the downlink direction from a cellular network. The user equipment estimates a received signal quality for each control signal in said set of control signals and determines, based on said received signal quality, which control signals have been reliably received. The user equipment derives one or more parameters related to the uplink transmit diversity operation using a subset of control signals from the set of control signals, said subset only including control signals determined as reliably received; and transmits in the uplink direction applying the derived one or more parameters to control the uplink transmit diversity operation. The accuracy of the transmit diversity parameter values derived/set by the UE can be improved. This will enhance the performance of the uplink transmit diversity and will also reduce interference to the neighbor cells.

摘要： In MU-MIMO scenarios, a target terminal can be exposed to data streams intended for other terminals. If the target terminal is capable of interference cancellation, then a network node, such as a base station or RNC, can provide the target terminal with interference information so that the target terminal can efficiently cancel interferences due to these interfering data streams. The interference information may include one or more interfering configuration, each of which characterizes a related interfering data stream. The interference information can also include the identity of the other terminal that is the intended recipient of the interfering stream. The network node may determine whether the target terminal can benefit from the interference information. If so, the network node can provide the interference information to the target terminal.
