Pre-emptive triggering for integrated access and backhaul for 5g or other next generation network

Abstract

In a 5G network, a pre-emptive scheduling request (SR) and a pre-emptive buffer status report (BSR) can be used to reduce the latency of data transmissions on the upstream of a multi-hop integrated access and backhaul (IAB) network from the user equipment UE to the IAB-donor node. A centralized unit (CU) can uniformly ensure that the pre-emptive SR/BSR feature is turned on or off across the entire IAB network regardless of which vendor provides the IAB nodes. Additionally, a message can be sent from a gNodeB to the CU to the IAB node to indicate whether the pre-emptive SR/BSR triggering feature is turned on or off.

What is claimed is: 
     
         1 . A method, comprising:
 receiving, by first network equipment comprising a processor, message data representative of a status associated with a sequencing pattern, wherein the status is an active status of the sequencing pattern;   receiving, by the first network equipment from second network equipment, scheduling request data representative of a scheduling request to send data via an uplink channel of a network; and   in response to receiving the scheduling request data, sending, by the first network equipment to third network equipment, the scheduling request data in accordance with the sequencing pattern.   
     
     
         2 . The method of  claim 1 , wherein the message data is received via a radio resource control signal. 
     
     
         3 . The method of  claim 1 , wherein the message data is received via a downlink control data channel. 
     
     
         4 . The method of  claim 1 , further comprising receiving, by the first network equipment from the third network equipment, uplink grant data representative of a grant for the second network equipment to send the data via the uplink channel of the network. 
     
     
         5 . The method of  claim 4 , further comprising sending, by the first network equipment, the uplink grant data to the second network equipment. 
     
     
         6 . The method of  claim 5 , further comprising receiving, by the first network equipment, buffer status data representative of a buffer status associated with the second network equipment. 
     
     
         7 . The method of  claim 1 , wherein the first network equipment comprises an integrated access and backhaul device of the network. 
     
     
         8 . First network equipment, comprising:
 a processor; and   a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
 receiving message data representative of a status associated with a message sequencing pattern, wherein the status is an active status of the message sequencing pattern; 
 receiving, from user equipment, scheduling request data representative of a scheduling request to transmit packet data; and 
 in response to receiving the scheduling request data, transmitting the scheduling request data to second network equipment pursuant to the message sequencing pattern. 
   
     
     
         9 . The first network equipment of  claim 8 , wherein the message data is received via a radio resource control signal. 
     
     
         10 . The first network equipment of  claim 8 , wherein the message data is received via a downlink control data channel. 
     
     
         11 . The first network equipment of  claim 8 , wherein the message data is received via a media access control element. 
     
     
         12 . The first network equipment of  claim 8 , wherein the operations further comprise receiving grant data representative of a grant for the user equipment to transmit the packet data to the second network equipment. 
     
     
         13 . The first network equipment of  claim 12 , wherein the operations further comprise transmitting the grant data to the user equipment. 
     
     
         14 . The first network equipment of  claim 13 , wherein the operations further comprise receiving buffer status data representative of an amount of the packet data to be transmitted to the second network equipment. 
     
     
         15 . The first network equipment of  claim 14 , wherein the operations further comprise transmitting the buffer status data to the second network equipment. 
     
     
         16 . The first network equipment of  claim 8 , wherein the message data is first message data and the status is a first status, and wherein the operations further comprise receiving second message data representative of a second status associated with the message sequencing pattern, wherein the second status is an inactive status of the message sequencing pattern. 
     
     
         17 . A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
 receiving message data representative of a status associated with a sequencing pattern, wherein the status is an active status of the sequencing pattern;   receiving, from user equipment, scheduling request data representative of a request to send packet data;   in response to receiving the scheduling request data, sending the scheduling request data to network equipment pursuant to the sequencing pattern;   receiving uplink grant data representative of a grant to send the packet data to the network equipment;   in response to receiving the uplink grant data, sending the uplink grant data to the user equipment;   receiving the packet data from the user equipment; and   in response to receiving the packet data, sending the packet data to the network equipment.   
     
     
         18 . The non-transitory machine-readable medium of  claim 17 , wherein the message data is received via at least one of a radio resource control signal, a downlink control data channel, or a media access control element. 
     
     
         19 . The non-transitory machine-readable medium of  claim 17 , wherein the message data is received via an access point interface. 
     
     
         20 . The non-transitory machine-readable medium of  claim 17 , wherein the operations further comprise sending acknowledgement data that acknowledges receiving the message data.
