Apparatus and method for resource sharing between a plurality of communication networks

Abstract: An apparatus for resource sharing between a plurality of communication networks (103, 107, 111) each having a nominal resource allocation of a shared air interface resource and a resource exchange allowance is provided. The apparatus (201) comprises a sharing instigation processor (205) which initiates a temporary resource allocation of a first air interface resource from a nominal resource allocation of a first network (103). A network interface (201) receives offer messages from a plurality of networks (107, 111). Each offer message comprises a resource exchange offer value for at least part of the first air interface resource. A selection processor (207) selects a second network (107) for example by selecting the highest offer value for a given resource. An allocation message generator (211) transmits a resource allocation message to the second network (107) indicating a temporary allocation of at least part of the first air interface resource. The resource exchange allowance of the second network (107) is then reduced by a value corresponding to the resource exchange offer value from the second network (107).

Communication system and method of sharing a communication resource

Abstract: A wireless communication system includes a communication resource with a number of Operators providing communication on the communication resource. A first portion of said communication resource is dedicated to a first Operator and a second portion of said communication resource is dedicated as a shared resource for shared use between at least two Operators within the communication system. A method of sharing a communication resource is also provided. This enables the sharing of frequencies, between proprietary and shared frequencies, by dynamically controlling a set of adjustable thresholds for call admission and termination, resulting in flexible spectrum sharing and an increase in spectrum efficiency. Such a mechanism to provide a flexible spectrum allocation is attained by moving thresholds and/or by instruction from a Central Controller

Resource Allocation for Uplink Grant-Free Ultra-Reliable and Low Latency Communications

Abstract: Ultra-Reliable and Low Latency Communications (URLLC) is an important emerging area for the fifth generation (5G) cellular network. The requirements for URLLC are as stringent as 1−10-5 reliability for a 32-byte packet with user plane latency of 1 ms. To achieve these requirements, grant-free transmission with repetitions of data packet has been recently proposed for uplink transmissions. However, the resource overhead and collisions among URLLC user equipments (UEs) become limiting factors to achieving optimal system performance. In this work, a hybrid resource allocation scheme is proposed to optimally allocate dedicated resource units and/or a shared resource pool to a group of UEs. Numerical results based on theoretical analysis show that the target requirements of URLLC can be achieved with up to 70% reduction in resource utilization compared to the conservative transmission scheme.
