摘要： The present disclosure proposes a solution that increases the efficiency of the MAC and use of the spectrum by indicating in a receiver channel reservation, RCR, signal that the channel is reserved only at the receiver side of a link, during the planned reception by the receiver. The disclosure relates to a method, performed in a first node 10a in a wireless communication system, of reserving a shared media for signal reception, the method comprising defining, parts of the shared media to reserve for signal reception in the first node 10a, configuring a receiver channel reservation signal 30 to indicate the defined parts and transmitting the receiver channel reservation signal 30 to reserve the shared media. The disclosure also relates to a method in a node receiving a receiver channel reservation, RCR, signal and to the corresponding network nodes.

摘要： The disclosure relates to future radio access systems and more specifically to methods for media access in future radio access systems. The present disclosure presents a method performed in a first node 10c in a wireless communication system, of accessing a shared channel for transmission from the first node to at least one second node 20d. The method comprises the step of receiving, from a third node a pilot signal announcing reception in the third node 10a, wherein the pilot signal comprises information enabling estimation of a channel response from the first node 10c to the third node 10a. The method further comprises estimating, using the pilot signal, a channel response from the first node to the third node and predicting, based on the estimated channel response, an interference level at the receiver of the third node of a directive transmission from the first node to the second node. The method finally comprises accessing the shared channel based on the predicted interference level. The presented method mitigates the problem of hidden nodes for directive transmissions. The disclosure relates to methods for reserving and accessing a shared media in radio access systems, as well as to wireless network nodes.

摘要： The proposed technology provides a computationally efficient way to find suitable routes under consideration of multiple metrics. The considered multi-hop network is represented by a connected graph having nodes and links interconnecting the nodes. The method comprises the step (S1) of obtaining a value of a reference route between a source node and a destination node in the connected graph according to a first routing metric. The method further comprises the step (S2) of modifying, based on the value of the reference route according to the first routing metric, the connected graph by modifying link cost, with respect to a second routing metric, of at least one link in the connected graph. The method also comprises the step (S3) of determining at least part of a route between the source node and the destination node in the modified connected graph, based on the modified link cost, according to the second routing metric.

摘要： Systems and methods are disclosed for adjusting Radio Link Monitoring, RLM, Radio Link Failure, RLF, detection, RLF recovery, and/or connection establishment failure detection for wireless devices (16) in a cellular communications network (10) depending on mode of operation. In one embodiment, a node (14, 16) in the cellular communications network (10) determines whether a wireless device (16) (e.g., a Machine Type Communication, MTC, device) is to operate in a long range extension mode of operation or a normal mode of operation. The node (14, 16) then applies different values for at least one parameter depending on whether the wireless device (16) is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters.

摘要： Systems and methods for computing and/or utilizing mutual information based link metrics for a link in a wireless mesh network are disclosed. In one embodiment, one or more mutual information values are computed for a link between a transmitter of a first network node and a receiver of a second network node in a wireless mesh network.

One or more link metrics for the link are computed as a function of the mutual information values, where each link metric is computed based on a different one of the one or more mutual information values. In this manner, a link metric is computed for each of the one or more hypothesized transmission modes for the link. At least one of the link metrics are then provided to a routing update module.

摘要： Code words are assigned to subscriber stations or groups of subscribe stations in a communication network for a quick paging mechanism in which the assigned code words are transmitted as quick paging signals over unused frequency resources to signal the subscriber stations. Subsets of multiple code words from a set of code words can be assigned to respective paging groups, and overlapping subsets can be assigned to multiple paging groups. This enables a single code word to be used to address either a single paging group or multiple paging groups.

摘要： A radio access network (RAN) (20) comprise a base station (28) and a wireless terminal (30). The base station 28 comprises a transceiver (38) and a frame handler (40), the wireless terminal (30) comprises a transceiver (48) and a wireless terminal frame handler (50). The frame handlers (40, 50) handle a enhanced frame F having enhanced frame structure. At least a down link portion of the frame is formatted and handled in a manner whereby the frame can be perceived as a first format type of frame if the wireless terminal is a first type of wireless terminal and perceived as an enhanced or second format type of frame if the wireless terminal is a second type of wireless terminal. The frame handler configures the frame as plural sub frames, each sub frame having a down link burst followed by an up link burst. The frame is preferably configured to afford the second type of wireless terminal sufficient time to develop an acknowledgement for a message transmitted in a down link burst, the acknowledgement being sent to the base station in an up link burst which is within one frame length of the message.
