Problems solved by technology

With this combined channel estimation, UE 102 cannot decode the system information in either beacon (so it will never know that the beacon was sent from a different AN), and cannot decode any subsequent data transmission from AN 112
[0010] In addition to the "PANI collision" problem described above, UE 102 may experience co-channel interference from AN 111 and / or AN 121
This co-channel interference to beacon transmissions will result in a degraded Signal-to-Interference Ratio (SIR) of the beacons received at the UE, which in turn reduces the ability of the UE 102 to successfully decode the beacons and establish a connection with the AN 112. possibility of

Embodiment Construction

[0036] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be noted that the following examples are illustrative only and do not limit the scope of the present disclosure.

[0037] Figure 4 is a flowchart illustrating a method 400 of coordinating beacon transmissions according to an embodiment of the disclosure. Method 400 may be performed at a network node (eg, figure 1 Executed at the AN 112) of the network 110 in . For example, a network node may be an evolved Node B (eNB) in an LTE network.

[0038] Method 400 includes the following steps.

[0039] In step S410, for each candidate time slot in a plurality of candidate time slots, it is determined whether the candidate time slot is used by any adjacent network node of the second network (for example, figure 1 The AN 121 of the medium network 120 is used for beacon transmission.

[0040] In the context of the present disclosure, a "neighboring"...

Abstract

The present disclosure provides a method (400) for coordinating beacon transmissions. The method (400) comprises, at a network node of the first network: determining (S410), for each candidate time slot of a plurality of candidate time slots, whether said candidate time slot is used by any neighboring network node of the second network For beacon transmission; selecting (S420) a candidate time slot among the plurality of candidate time slots that is determined not to be used for beacon transmission by any neighboring network node of the second network as a beacon time slot; and Transmitting (S430) a beacon in said beacon slot.

Description

technical field [0001] The present disclosure relates to wireless communications, and more particularly to methods and network nodes for coordinating beacon transmissions. Background technique [0002] In order to provide large bandwidth and high capacity coverage, access nodes (ANs) in a network usually share the entire spectrum available in the network. For example, in millimeter wave (mmW) networks, multiple "islands of high-capacity coverage" are deployed, and each of these islands can reuse the entire spectrum available in the mmW network. [0003] figure 1 An example scenario of spectrum reuse is shown. figure 1 Two networks are shown in , network 110 and network 120 . Such as figure 1 As shown by the dashed line in , the coverage area of ​​network 110 and the coverage area of ​​network 120 partially overlap each other. Networks 110 and 120 may belong to different network operators and may be allocated the same frequency spectrum. Network 110 includes two ANs, AN...
