Abstract: The power requirements of user equipments (UEs) are expected to increase as their capabilities increase. Some power saving methods have previously been proposed, but are limited by the radio resource control (RRC) protocol and do not address the power consumption associated with having to transition between different RRC states. In some embodiments described herein, there are not different RRC states, but instead a single RRC state. Within that single RRC state, there are different modes of operation, e.g. a default low power operation mode and an enhanced power operation mode. In some embodiments, the UE switches from the default operation mode to the enhanced operation mode on an on-demand basis (e.g. based on the communication capability required by the UE), and then returns back to the default operation mode.

Abstract: The power requirements of user equipments (UEs) are expected to increase as their capabilities increase. Some power saving methods have previously been proposed, but are limited by the radio resource control (RRC) protocol and do not address the power consumption associated with having to transition between different RRC states. In some embodiments described herein, there are not different RRC states, but instead a single RRC state. Within that single RRC state, there are different modes of operation, e.g. a default low power operation mode and an enhanced power operation mode. In some embodiments, the UE switches from the default operation mode to the enhanced operation mode on an on-demand basis (e.g. based on the communication capability required by the UE), and then returns back to the default operation mode.

Abstract: It is desired to try to reduce power consumption in a transmit-and-receive point (TRP) in a wireless network. In some embodiments, to try to reduce overall power consumption, multiple (e.g. two) sets of radio frequency (RF) components are utilized by a TRP, one set having lower power consumption than the other set(s), and switching between the different sets during operation. For example, a TRP may include a first radio frequency unit (RFU) and a second RFU. The second RFU is designed to have higher power consumption than the first RFU. During operation, the TRP uses the second RFU to perform wireless communication in response to a trigger, and otherwise uses the first RFU to perform wireless communication.

Abstract: A scheduler of a radio access network node may determine that at least one quality parameter corresponds to a traffic flow. Based on determining that a quality parameter, such as a priority or a latency, corresponds to the flow, the node scheduler may determine a scheduling of radio resources usable to transmit a packet of the flow. The scheduling of the resources may comprise using a conservative modulation coding scheme, high transmit power, additional antennas, or a low coating rate to increase the likelihood that a packet is successfully transmitted and received. If a quality parameter is a latency budget, and an unsuccessful transmission, and subsequent retransmission, of the packet would not violate the latency budget, the scheduler may adjust the resources such that the packet is transmitted in a less conservative manner.

Abstract: A radio access network node may configure multiple user equipment to use different bandwidth parts via a bandwidth part configuration. The bandwidth part configuration may define one or more radio resources that may be shareable between the bandwidth parts. Based on determined usage of the bandwidth parts, the node may assign the shareable resources from a lightly-loaded bandwidth part to a heavily-loaded bandwidth part during a resource sharing period. The node may transmit a bandwidth part resource assignment indication to user equipment using the lightly and heavily loaded bandwidth parts to indicate the assignment of the shareable resources and the node may refrain from transmitting an indication of the assignment to unaffected user equipment. A determination to assign/reassign the shareable resources may be based on different qualities-of-service performance targets corresponding to the lightly and heavily loaded bandwidth parts or corresponding to radio resource slices supported by the bandwidth parts.

Abstract: A radio access network node may comprise a centralized unit and a distributed unit. The distributed unit may transmit to the centralized unit a status message comprising information elements indicative of utilization of bandwidth part slice radio resources. Based on the utilization information elements in the status message, the centralized unit may determine to reallocate bandwidth part resources from one bandwidth part to another. The centralized unit may instruct the distributed unit to implement a reallocation of the bandwidth part radio resources from the one bandwidth part to the other bandwidth part. The distributed unit may notify affected user equipment of the reallocation of bandwidth part radio resources.
