    摘要: A technique for differentiating licensed-assisted-access (LAA) cells (on which a UE may not be allowed to camp) from non-LAA cells (on which a UE may camp) including making at least one type of idle-mode cell selection measurement for at least one carrier in time resources determinable from broadcast system information; and refraining from making said at least one type of idle-mode cell selection measurement for said at least one carrier outside of said time resources; in alternative, the technique including creating a specific type of DRS for non-LAA cells which may be recognized by the UE (e. g., the DRS including an additional PSS sequence or being scrambled with a network-specific signature).

    摘要: Systems, methods, apparatuses, and computer program products for generating sequences for zero-tail discrete fourier transform (DFT)-spread-orthogonal frequency division multiplexing (OFDM) (ZT DFT-s-OFDM) reference signals. One method includes adding a zero vector to an input sequence, and performing an iterative manipulation of the input sequence. The performing of the iterative manipulation of the input sequence may include, for example: computing frequency domain response of the sequence, normalizing elements of the computed frequency domain sequence to unitary power while maintaining phase of each of the elements, converting the sequence to time domain, generating a zero-padded sequence by forcing a zero head and tail of the sequence, and repeating the steps until a final sequence with zero-tail and flat frequency response is obtained.

    摘要: Apparatus and method for resource allocation are provided. An apparatus includes a controller which is configured to utilize a tree structure with more than one branch in the resource allocation of physical resource blocks, each branch including one or more legal starting positions for resource allocation. Each starting position is associated with a cluster of physical resource blocks, the number of starting positions being different on each branch. The size of the resource clusters of each branch is different. The controller is configured to denote each resource cluster with a predefined index, and allocate one or more clusters to user equipment uplink connection.

    摘要: Methods and apparatuses are disclosed for controlling communications devices. An access node can generate a message for at least one communication device for transmission at a resource determined at least partly on the basis of a first identifier value assigned to said at least one communication device. The generation comprises including in the message at least one other identifier value, wherein the other identifier values are assigned to communication devices for a purpose of addressing messages to communication devices. The at least one other identifier value is used exclusively for said at least one communication device at said resource and is recognisable to said at least one communication device as instruction to take one or more actions associated with the at least one other identifier value. A communication device can check for a message at the resource, the checking comprising checking in the message for the one or more other identifier values. In response to detecting one or more of said one or more other identifier values, said communication device can take one or more actions associated with said detected one or more of said one or more other identifier values.

    摘要: An example technique is provided for receiving, by a target base station (BS) from a source PS, information identifying a source cell or the source BS, and a first time advance value used by the user device to transmit signals to the source BS, receiving a signal by the target BS that was transmitted from the user device based on the first tune advance value, determining, by the target BS based upon the first time advance value and the received signal from the user device, a second time advance value to be used by the user device to transmit data to the target BS, sending the second time advance value from the target BS to the source BS, receiving, by the target BS, a handover of the user device from the source BS to the target BS, and receiving data by the target BS from the user device based on the second time advance value.
