摘要： The present disclosure relates methods, a device and a system for evaluation of channel estimate. One method is performed in a first access point 110a arranged to communicate with one or more wireless devices 10a, 10b through information streams that are created using multiple co-located antennas. The method comprises transmitting S1 or receiving S1b a packet A, to/from, the first wireless device 10a, wherein the packet A is transmitted using a precoder determined using the channel estimate, retrieving S4 information about possibly interfering transmissions C between further access points 110b in the vicinity of the first access point 110a, and respective second wireless devices 10c, 10d; wherein the information comprises location information and timing information related to the possibly interfering transmissions, determining S5 spatial separations between the transmissions A and C and evaluating S7 the channel estimate, based on the determined spatial separations.

摘要： A message (300) that has been transmitted in a mesh network from a source node (102) and intended for reception by a destination node (104) is received by a relay node (125) and also received by a number of other nodes (121, 123). A minimized latency can be obtained by the use of a timer such that the message is relayed by the relay node (125) only if no other node has already relayed the message.

摘要： One dimension (real or imaginary) is selected for each of a first plurality of devices that receives one-dimensional modulated complex signals from an access point (AP). The AP uses the selected dimension to generate a modulated complex signal for transmission to each such device, where the signal received by such devices is substantially free of inter-user interference on the dimension selected for the corresponding device. The AP then transmits the complex signal to the devices. As a result, the AP puts the modulated symbols received by of the first plurality of devices are received on either a real part or an imaginary part, but not both, and thus reduces the energy consumption associated with the transmission. Each of the first plurality of wireless devices considers either the real part or the imaginary part of the received signals.

摘要： A path of relay nodes is set up in a mesh network (100) between a source node (102) and a destination node (104). During a phase of handling path request, PREQ, messages a cluster table is maintained in a node (123) and during a phase of handling path reply, PREP, messages this cluster table is utilized to establish node clusters (120) that comprise nodes that can relay subsequent messages between the source node (102) and the destination node (104).

摘要： Embodiments herein relate to a method performed by a network node for enabling channel estimation in a wireless communications network. The wireless communications network comprises includes at least a first and a second Access Point, AP, having overlapping cells using contention-based transmission resources of the same frequency. The first network node controls the first AP to transmit information indicating that wireless devices served by the first AP are not to contend for the contention-based transmission resources when the second AP is transmitting a Null Data Packet, NDP. Then, the first network node controls the second AP to transmit a NDP. Embodiments of the first network node are also described. Embodiments herein also relate to a method performed by a wireless device for enabling channel estimation in a wireless communications network, and embodiments of the wireless device.
