allocate a beacon resource pattern from a predetermined set of beacon resource patterns to the detected UNd; and signal information about the allocated beacon resource pattern to the UNd. ## Claims ### Claim 1 An access node (ANd) for allocating a beacon resource pattern to a user node (UNd), wherein the ANd comprises: a receiver, configured to receive an uplink beacon signal from the UNd; a processor, configured to: detect the UNd based on receiving the uplink beacon signal from the UNd; allocate a beacon resource pattern, from a predetermined set of beacon resource patterns, to the detected UNd; and signal information about the allocated beacon resource pattern to the UNd; wherein the processor is further configured to: determine that beacon utilization of the UNd is lower than a threshold limit, wherein the beacon utilization corresponds to a ratio between a number of used beacon resources and a number of available resources of a currently allocated beacon resource pattern; and in response to determining that the beacon utilization of the UNd is lower than the threshold limit, allocate a beacon resource pattern with a lower beaconing rate than the currently allocated beacon resource pattern to the UNd. ### Claim 2 (depends on 1) The ANd according to claim 1, wherein the processor is further configured to: allocate the beacon resource pattern with the highest possible beacon rate in the predetermined set of beacon resource patterns to the detected UNd. ### Claim 3 (depends on 1) The ANd according to claim 1, wherein the processor is further configured to: adjust the allocated beacon resource pattern based on a signal rate limiting parameter of received uplink beacon signals; and signal information to the UNd comprising the adjusted allocated beacon resource pattern. ### Claim 4 (depends on 3) The ANd according to claim 3, wherein the signal rate limiting parameter comprises at least one rate or at least one quality of the received uplink beacon signals. ### Claim 5 (depends on 1) The ANd according to claim 1, wherein the processor is further configured to: determine that a second beacon utilization of the UNd exceeds the threshold limit; and in response to determining that the second beacon utilization of the UNd exceeds the threshold limit, allocate a beacon resource pattern with a higher beaconing rate than a second currently allocated beacon resource pattern to the UNd. ### Claim 6 (depends on 1) The ANd according to claim 1, wherein the processor is further configured to: allocate the beacon resource pattern to the detected UNd during a predetermined validation time; and signal information comprising at least the predetermined validation time of the allocated beacon resource pattern to the UNd. ### Claim 7 A method for allocating a beacon resource pattern to a user node (UNd), wherein the method comprises: detecting, by an access node (ANd), the UNd based on receiving an uplink beacon signal from the UNd; allocating, by the ANd, a beacon resource pattern, from a predetermined set of beacon resource patterns, to the detected UNd; and signalling, by the ANd, the allocated beacon resource pattern to the UNd; wherein the method further comprises: determining, by the ANd, that beacon utilization of the UNd is lower than a threshold limit, wherein the beacon utilization corresponds to a ratio between a number of used beacon resources and a number of available resources of a currently allocated beacon resource pattern; and allocating, by the ANd, a beacon resource pattern with a lower beaconing rate than the currently allocated beacon resource pattern to the UNd. ### Claim 8 (depends on 7) The method according to claim 7, wherein allocating the beacon resource pattern to the detected UNd further comprises: allocating the beacon resource pattern with the highest possible beacon rate in the predetermined set of beacon resource patterns to the detected UNd. ### Claim 9 (depends on 7) The method according to claim 7, further comprising: adjusting the allocated beacon resource pattern based on a signal rate limiting parameter of received uplink beacon signals; and signalling information to the UNd comprising the adjusted allocated beacon resource pattern. ### Claim 10 (depends on 9) The method according to claim 9, wherein the signal rate limiting parameter comprises at least one rate or at least one quality of the received uplink beacon signals. ### Claim 11 (depends on 7) The method according to claim 7, further comprising: determining that a second beacon utilization of the UNd exceeds the threshold limit; and in response to determining that the second beacon utilization of the UNd exceeds the threshold limit, allocating a beacon resource pattern with a higher beaconing rate than a second currently allocated beacon resource pattern to the UNd. ### Claim 12 (depends on 7) The method according to claim 7, wherein the beacon resource pattern is allocated to the detected UNd during a predetermined validation time; and wherein the method further comprises signalling information comprising at least the predetermined validation time of the allocated beacon resource pattern to the UNd. ### Claim 13 A non-transitory computer-readable medium having processor-executable instructions stored thereon, wherein the processor-executable instructions, when executed, facilitate: detecting a user node (UNd) based on receiving an uplink beacon signal from the UNd; allocating a beacon resource pattern, from a predetermined set of beacon resource patterns, to the detected UNd; and signalling the allocated beacon resource pattern to the UNd; wherein the processor-executable instructions, when executed, further facilitate: determining that beacon utilization of the UNd is lower than a threshold limit, wherein the beacon utilization corresponds to a ratio between a number of used beacon resources and a number of available resources of a currently allocated beacon resource pattern; and allocating a beacon resource pattern with a lower beaconing rate than the currently allocated beacon resource pattern to the UNd. ### Claim 14 (depends on 13) The non-transitory computer-readable medium according to claim 13, wherein allocating the beacon resource pattern to the detected UNd further comprises: allocating the beacon resource pattern with the highest possible beacon rate in the predetermined set of beacon resource patterns to the detected UNd. ### Claim 15 (depends on 13) The non-transitory computer-readable medium according to claim 13, wherein the processor-executable instructions, when executed, further facilitate: adjusting the allocated beacon resource pattern based on a signal rate limiting parameter of received uplink beacon signals;
