摘要： Methods and apparatus are disclosed for distributing access information in a multi-operator scenario. In a multi-operator network (100), network nodes (130, 140, 150) are configured to transmit one or more system signatures and one or more access information tables. A terminal device (200) can use a received system signature to retrieve a set of system information from an access information table. The retrieved system information is used by the terminal device (200) to initiate a random access procedure to gain access to an operator network.

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 wireless device is configured with a plurality of channel-sensing resources, each channel-sensing resource being associated with at least one corresponding transmission resource. The wireless device evaluates (810), in response to a determination that first data is ready to be transmitted by the wireless device, whether one or more of the plurality of channel-sensing resources are occupied, and transmits (820) at least a part of the first data on at least one transmission resource associated with at least one channel-sensing resource, in response to detecting that the at least one of the plurality of channel-sensing resources is not occupied. The wireless device further receives (830) a grant for a scheduled transmission at least partly overlapping with at least one of said plurality of channel-sensing resources; and transmits (840) second data in accordance with the received grant.

The disclosure provides for a method in a wireless device, of selecting random access resources for performing a random access procedure to a wireless network. The method comprises the step receiving information from a radio network node comprised in a cell of the wireless network, wherein the received information indicates at least a first and a second random access resource having different resource sizes. The method further comprises selecting one of said at least first and a second random access resources based on an expected uplink power received by the radio network node and transmitting a random access message to said wireless network using the selected resource. The disclosure further relates to methods for providing random access resources, as well as to a wireless device, and to radio network nodes of a wireless network.

摘要： A method of operating a wireless communication device in a wireless communication network is disclosed. The wireless communication device transitions between a plurality of modes, wherein the plurality of modes further includes a sleep mode, wherein the wireless communication device does not listen for downlink data transmissions, and the plurality of modes further includes an active mode, wherein the wireless communication device listens for downlink data transmissions. While the wireless communication device is operating in the active mode, it receives control signalling from a transmitter to adjust a length of time for transitioning between a first mode among the plurality of modes and a second mode among the plurality of modes based on one or more sleep rules. The wireless communication device transitions from the first mode to the second mode based, at least in part, on the adjusted length of time.

摘要： A first channel for carrying Layer 2 messages carries data that will not be retransmitted and for which decoding-related information need not be retained by the receiving node in the event of an unsuccessful decoding of the data, while a second channel carries data that will be retransmitted in the event that a negative acknowledgement is received by the transmitting node. In an example method, first and second subsets of Layer 2 messages are received on first and second physical data channels, respectively. Decoding-related information for unsuccessfully decoded messages in the first subset is retained for use with subsequent retransmissions, while decoding-related information for unsuccessfully decoded messages in the second subset is discarded without waiting for retransmissions. Acknowledgements or negative acknowledgements are sent for messages in the first subset, but may or may not be sent for messages in the second subset, in various embodiments.
