Abstract
Disclosed are methods, systems, apparatus, and computer programs for communicating new link availability configurations for a node in an integrated access and backhaul (IAB) network. In one aspect, a method includes receiving a Radio Resource Control (RRC) message from an IAB node; determining, based on the RRC message, a new resource availability configuration for a backhaul resource associated with the IAB node; and in response to determining the new resource availability configuration, conditionally communicating with the IAB node over the backhaul resource according to the new resource availability configuration.
Claims20
A method comprising:
- receiving, from an integrated access and backhaul (TAB) central unit node, a Radio Resource Control (RRC) message that includes an uplink-downlink configuration setting;
- determining, using at least in part the uplink-downlink configuration setting from the RRC message, a new resource availability configuration for a backhaul resource associated with the IAB central unit node, wherein the new resource availability configuration includes a hard resource availability bitmap having one or more first bits and a soft resource availability bitmap having one or more second different bits, wherein each bit in the hard resource availability bitmap and the soft resource availability bitmap corresponds to a different backhaul resource associated with the IAB central unit node;
- and
- in response to determining the new resource availability configuration, conditionally communicating with the IAB central unit node over the backhaul resource according to the new resource availability configuration.
A method comprising:
- determining, by an integrated access and backhaul (IAB) central unit node, a new resource availability configuration for a backhaul resource associated with an IAB node and a degree of availability of the backhaul resource;
- generating, in response to determining that the new resource availability configuration that indicates that the backhaul resource is unavailable, a Radio Resource Control (RRC) message comprising the new resource availability configuration for the backhaul resource in an uplink-downlink configuration setting that includes a first parameter that indicates that the backhaul resource is not hard available and a second different parameter indicates that the backhaul resource is not soft available;
- and
- transmitting the RRC message that includes the uplink-downlink configuration setting to the IAB node.
An apparatus for an integrated access and backhaul (TAB) network comprising a non-transitory computer-readable storage device having stored thereon instructions, which, when executed by one or more processors, cause the one or more processors to perform operations comprising:
- receiving, from an TAB central unit node, a Radio Resource Control (RRC) message that includes an uplink-downlink configuration setting;
- determining, using at least in part the uplink-downlink configuration setting from the RRC message, a new resource availability configuration for a backhaul resource associated with the TAB central unit node, wherein the new resource availability configuration includes a hard resource availability bitmap having one or more first bits and a soft resource availability bitmap having one or more second different bits, wherein each bit in the hard resource availability bitmap and the soft resource availability bitmap corresponds to a different backhaul resource associated with the TAB central unit node;
- and
- in response to determining the new resource availability configuration, conditionally communicating with the TAB central unit node over the backhaul resource according to the new resource availability configuration.
