Method and system for allocating PUCCH resources to user equipments in a communication network
The present disclosure relates to method and resource allocation entity for allocating Physical Uplink Control Channel (PUCCH) resources to User Equipments (UEs) in a communication network. The method comprises identifying one or more PUCCH resource pools to be allocated to cell camped on by one or more UEs, based on one or more first parameters associated with cell, using machine learning model. Further, the method comprises identifying one or more PUCCH resources to be allocated to each UE, based on one or more PUCCH resources pools and one or more second parameters associated with corresponding UE, using machine learning model. The method comprises allocating one or more PUCCH resource sets from plurality of PUCCH resource sets to each UE, based on one or more PUCCH resources identified for each UE and one or more parameters of plurality of PUCCH resource sets.
1. A method performed by a resource allocation entity associated with a base station in the communication network in a communication network, the method comprising:
identifying, by the resource allocation entity, one or more physical uplink control channel (PUCCH) resource pools to be allocated to a cell camped on by one or more user equipments (UEs) based on one or more first parameters associated with the cell, using a machine learning model;
identifying, by the resource allocation entity, one or more PUCCH resources to be allocated to a UE from the one or more UEs, based on the one or more PUCCH resource pools and one or more second parameters associated with the UE, using the machine learning model; and
allocating, by the resource allocation entity, one or more PUCCH resource sets from a plurality of PUCCH resource sets to the UE from the one or more UEs, based on the one or more PUCCH resources identified for the UE and one or more parameters of the plurality of PUCCH resource sets.
2. The method as claimed in claim 1 , wherein the one or more PUCCH resource sets are allocated to transmit at least one of a scheduling request (SR), channel state information (CSI), or hybrid automatic repeat request-acknowledge/negative acknowledge (HARQ-ACK/NACK).
3. The method as claimed in claim 1 , wherein the one or more first parameters include at least one of a physical random-access channel (PRACH) configuration of the cell and neighboring cells, a transmission mode of the cell, a subcarrier spacing (SCS) value configured in the cell, a maximum number of UEs supported in the cell, a maximum number of scheduling requests (SRs) supported in the cell, a bandwidth associated with the cell, or a presence of dynamic spectrum sharing slots and resource sets in the cell.
4. The method as claimed in claim 1 , wherein the one or more second parameters include at least one of quality of service (QoS) class identifiers (QCI) characteristics of one or more services required by the UE, one or more UE capabilities, historical latency observations associated with PUCCH resources allocated to the one or more services, or a type of the UE in the cell.
5. The method as claimed in claim 1 , wherein the one or more parameters include a periodicity and an offset associated with corresponding PUCCH resource set.
6. The method as claimed in claim 1 , wherein the one or more parameters are determined by the machine learning model based on the one or more first parameters.
7. A resource allocation entity associated with a base station in a communication network, the resource allocation entity comprising:
one or more processors; and
a memory storing processor-executable instructions, which, on execution, cause the one or more processors to:
identify one or more physical uplink control channel (PUCCH) resource pools to be allocated to a cell camped on by one or more user equipments (UEs), based on one or more first parameters associated with the cell, using a machine learning model;
identify one or more PUCCH resources to be allocated to a UE from the one or more UEs, based on the one or more PUCCH resource pools and one or more second parameters associated with the UE, using the machine learning model;
allocate one or more PUCCH resource sets from a plurality of PUCCH resource sets to each UE from the one or more UEs, based on the one or more PUCCH resources identified for the UE and one or more parameters of the plurality of PUCCH resource sets.
8. The resource allocation entity as claimed in claim 7 , wherein the one or more processors are configured to allocate the one or more PUCCH resource to transmit at least one of a scheduling request (SR), channel state information (CSI), or hybrid automatic repeat request-acknowledge/negative acknowledge (HARQ-ACK/NACK).
9. The resource allocation entity as claimed in claim 7 , wherein the one or more first parameters include at least one of physical random-access channel (PRACH) configuration of the cell and neighboring cells, a transmission mode of the cell, a subcarrier spacing (SCS) value configured in the cell, a maximum number of UEs supported in the cell, a maximum number of scheduling requests (SRs) supported in the cell, bandwidth associated with the cell, or a presence of dynamic spectrum sharing slots and resource sets in the cell.
10. The resource allocation entity as claimed in claim 7 , wherein the one or more second parameters include at least one of quality of service (QoS) class identifiers (QCI) characteristics of one or more services required by the UE, one or more UE capabilities, historical latency observations associated with PUCCH resources allocated to the one or more services, or a type of the UE in the cell.
11. The resource allocation entity as claimed in claim 7 , wherein the one or more parameters include a periodicity and an offset associated with corresponding PUCCH resource set.
12. The resource allocation entity as claimed in claim 7 , wherein the one or more parameters are determined by the machine learning model based on the one or more first parameters.
