Abstract: Methods and apparatus in a communication system for search space switching are disclosed. A method performed by a network node in a communication system that includes more than one search space group includes generating a downlink control information, DCI, message, and transmitting the DCI message on a downlink control channel, wherein the DCI message causes a user equipment, UE, to switch from monitoring a first search space group to monitoring a second search space group in response to successfully decoding the DCI message. A method performed by a UE in the communication system, wherein the UE is configured to monitor a first search space group, includes receiving a DCI message on a downlink control channel; and switching from monitoring the first search space group to monitoring a second search space group in response to successfully decoding the DCI message.

Abstract: An access node (110) configures a User Equipment, UE (105), with a power saving monitoring pattern, and subsequently transmits a power saving signal configured to switch the UE (105) from monitoring a downlink in accordance with a connected mode discontinuous reception, C-DRX, monitoring pattern to monitoring the downlink in accordance with the power saving monitoring pattern. For each of the monitoring patterns, monitoring the down-link in accordance with the monitoring pattern comprises monitoring the down-link only when a monitoring opportunity of the monitoring pattern is concurrent with a scheduled active interval of a C-DRX configuration of the UE (105). For any C-DRX cycle of the C-DRX configuration, the monitoring of the downlink in accordance with the power saving monitoring pattern has a shorter monitoring duration than the monitoring of the downlink in accordance with the C-DRX monitoring pattern.

Abstract: A simulated Public Warning System (PWS) message is defined for efficient PWS testing. The simulated PWS message mimics a conventional PWS message, but indicates that it is not to be propagated across an air interface to UEs. However, the simulated PWS message is otherwise propagated through the network as a PWS message. This allows for testing the generation and propagation of PWS messages, without wasting valuable air interface and battery resources. In some embodiments, network nodes may initiate testing by requesting a simulated PWS message. An Access and Mobility management Function (AMF) node in a wireless communication network collects and reports network status to a PWS entity. The AMF node ascertains the functionality of network functions, nodes, and interfaces to which it is connected, independently from receiving reports of such functionality, and an indication of any detected fault or failure is sent to the PWS entity.

Abstract: Power savings is achieved by configuring the UE with a sparse search space for power savings and a packed search space for normal PDCCH monitoring. The network is aware of the search space being monitored by the UE and can signal the UE to switch between the two search spaces by sending downlink control information (DCI) to the UE in the search space being monitored by the UE. To conserve power, the network switches the UE to the sparse search space for PDCCH monitoring, which requires less energy than PDCCH monitoring in the packed search space. When the network expects to have downlink data to send, the network sends downlink control information (DCI) to the UE in the sparse search space to cause the UE to switch to the packed search space. The DCI may comprise scheduling information, or a WUS-like signal indicating that the UE should switch search spaces for PDCCH monitoring.

Abstract: Embodiments include methods, performed by a user equipment (UE), for selective transmission or reception of signals or channels with a wireless network. Such methods include receiving a first physical downlink control channel (PDCCH) transmission from the wireless network. Such methods also include, without determining whether a signal or channel is scheduled for the UE during a first duration immediately following the first PDCCH transmission, refraining from transmitting or receiving any signals or channels during the first duration. The first duration can be based on one or more of the following: predicted scheduling characteristics for the PDCCH; UE operating conditions; and communication characteristics of an application running on the UE. In some embodiments, such methods can also include determining the predicted scheduling characteristics based on a plurality of second PDCCH transmissions received, from the wireless network, before the first PDCCH transmission.
