Description

resource allocation and determination methods, node and second node

Technical Field

The invention relates to the technical field of wireless communication, in particular to resource configuration and determination methods, a node and a second node.

Background

In order to reduce the cost of the optical fiber requirement, an Access Backhaul (Integrated Access and Backhaul, abbreviated as IAB) technology needs to be used, and a Backhaul function is added to the Access function of the high-frequency base station, so that the high-frequency deployment can be realized without connecting the optical fiber with a core network and using a wireless link.

In a Long Term Evolution (Long Term Evolution, LTE for short), similar wireless backhaul functions are supported, namely, a relay technology, in a 5G high-frequency application scenario, part of the relay technology can be used, but in consideration of the density of a deployment scenario, 5G increases support for a multi-hop and multi-connection scenario.

Therefore, after the IAB node is accessed to the network, when Backhaul (Backhaul) and Access (Access) are performed, considering that a high-frequency link is easy to be blocked, the quality of other alternative links in the network needs to be monitored at the same time, so that when a main Backhaul link is blocked, the IAB node can be switched to other available alternative nodes in time to continue Backhaul, and the robustness is improved. In the prior art, in order to improve backhaul robustness of an IAB node (IAB node), an IAB node/base station (Donor gNB, abbreviated as DgNB) needs to send an inter-node discovery signal, and at least provides a synchronization function, and the IAB node needs to monitor discovery signals sent by a parent node and other nodes and used between the IAB nodes. Considering half-duplex limitation of the IAB node, the IAB node cannot receive the synchronization signal of the Backhaul link while serving the Access link user. Therefore, the discussion direction of the standard is to transmit the discovery signal between nodes on the time division resource except the synchronization signal resource used by the Access user, as shown in fig. 1, the IAB node 1 and the IAB node 2 both transmit the synchronization signal of the Access link user to ensure the synchronization of the Access user, and the IAB node 1 cannot monitor the synchronization signal transmitted by the IAB node 1 on the resource for transmitting the synchronization signal. The IAB node 1 sends a discovery signal on a time division resource 11 except a synchronous signal resource used by a sending access user, and the IAB node 2 monitors the discovery signal sent by the IAB node 1 on a corresponding time division resource 12.

According to the existing scheme, the discovery signals among the nodes are sent on time division resources except the synchronous signals used by the access users, which can ensure that behaviors of the IAB nodes for receiving the discovery signals among the nodes do not influence the sending of the synchronous signals of the access users serving the IAB nodes, but the IAB nodes cannot send the discovery signals simultaneously when receiving the discovery signals, and in the densely deployed network, each IAB node needs to send and receive the signals among the nodes.

Therefore, how to determine the resource of the node for sending the discovery signal to ensure the mutual discovery between the nodes is a technical problem to be solved at present.

The base station is also called a node (node), and refers to an anchor point where an optical fiber is connected to a core network.

IAB nodes (IAB nodes) refer to nodes that do not have a fiber connection and a core network, but can backhaul through a wireless link, and can provide access functions, such as

IAB nodes

In preferred embodiments of the present invention, the step of determining actual transmission resources and/or resource sets of signals is preceded by the steps of:

Wherein the configuration information may be configured by high layer signaling of an upper level node.

In still other preferred embodiments of the present invention, the resource available for transmitting the th signal is as agreed upon by a protocol.

That is, the second node determines an actual transmission resource and/or a resource set of signals from among the resources available for transmitting signals as agreed upon by the protocol according to its characteristic parameters.

For example:

step 1, series of time slots are appointed by superior nodes or protocols for resource S capable of sending signal_dicoveryThe method comprises the steps of occupying S time slots in total, setting the sequence numbers as time slots 0, 1, … and S-1, configuring or appointing the maximum number Q of the time slots which can be transmitted by each lower node through a protocol, and simultaneously configuring or appointing parameters N through the protocol.

And 2, the lower IAB node determines the parameter i to be ID mod N according to the ID information of the lower IAB node, and further determines the position where the lower IAB node can actually send the th signal.

The IAB node i determines the number of the time slots actually available for the generation of the th signal, P × N + (i-1) × Q: P × N + i × Q-1, where P is floor (S/(N-1)).

For another example:

step 1, series of time slots are appointed by superior nodes or protocols for resource S capable of sending signal_dicoveryThe total occupies S time slots, and the serial numbers are time slots 0, 1, … and S-1 respectively; configuring or agreeing on each subordinate via a protocolThe maximum number N of nodes capable of sending Synchronous Signal Blocks (SSBs)_SSBThe th signal is a synchronous signal, and parameters M are configured or agreed by a protocol at the same time.

And 2, the lower IAB node determines a parameter i-cell ID mod M according to the cell ID information and further determines the position where the lower IAB node can actually send the th signal.

The IAB node i determines the actual time slot number of th signal_SSB:(i+1)*N_SSB-1。

It is also possible to determine Cell-specific (Cell-specific) resources by the superior node or by agreement, and the subordinate IAB node determines the corresponding offset (offset) between the discovery signal transmission position and the start position according to its own Cell-ID or IAB ID or other ID.

For example:

step 1, initial positions Slot n are configured by superior nodes or agreed by protocols₀ th signal, and parameters L are configured or agreed upon by the protocol.

Step 2: the IAB node obtains the parameters L and n according to the obtained parameters₀Determining the start position n of the th signal which can be actually sent₀+(Cell ID mod N)*n_discoveryThen the IAB node determines that the time slot sequence number actually available for the generation of the th signal is n₀+(Cell ID mod N)*n_discovery：n₀+(Cell ID mod N)*n_discovery+n_discovery。

Wherein n is_discoveryThe maximum number of slots of th signal predefined for the protocol, or n_discoveryThe number of available slots for discovery signals for each IAB node that may also be configured for an upper level node.

Referring to fig. 7, in a specific application scenario of , a base station sends configuration information to each of lower nodes IAB node 1, IAB node 2, IAB node 3, and IAB node 4, where IAB node 1 sends a signal on backhaul link transmission resource 712 according to the configuration information and listens to a signal sent by other IAB nodes on resource 711, IAB node 2 sends a signal on backhaul link transmission resource 721 according to the configuration information and listens to a signal sent by other IAB nodes on resource 722, IAB node 3 sends a signal on backhaul link transmission resource 732 and listens to a signal sent by other IAB nodes on resource 731, and IAB node 4 sends a signal on backhaul link transmission resource 741 according to the configuration information and listens to a signal sent by other IAB nodes on resource 742, so that IAB node 1 and IAB node 2, IAB node 2 and IAB node 3, IAB node 3 and IAB node 4 can discover each other IAB nodes.
