A method is disclosed herein for reducing energy consumption in a wireless device. A wireless device (e.g., a user equipment) can provide an indication to a network node (e.g., a base station) to indicate that the wireless device will prioritize energy consumption reduction over some network requirements (e.g., latency and/or scheduling flexibility requirements). Accordingly, the wireless device can perform certain power-saving actions to reduce energy consumption. The network node, upon receiving the indication from the wireless device, can perform certain network-related actions to assist the wireless device in reducing energy consumption. As a result, it is possible for the wireless device to reduce energy consumption and complexity, thus helping to prolong battery life in the wireless device.

Methods and devices for reducing UE energy consumption

Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.

Industrial automation with 5G and beyond

A method () by a wireless device () includes transmitting (), to a network node (), a request for a preconfigured uplink resource, PUR, configuration. The wireless devicereceives the PUR configuration from the network node, and the PUR configuration comprising time and/or frequency resources for transmitting on an uplink. The wireless device determines a PUR start time based on a value associated with a hyper system frame number (HSFN), a HSFN cycle, and/or a subframe number. The PUR start time measured relative to a time associated with the PUR configuration.

Calculation of preconfigured uplink resource occasion start time and periodic timing

Systems and methods for determining timing advance (TA) validity are disclosed. In some embodiments, systems and methods are disclosed herein in which a wireless device implicitly considers a TA to be valid in a full cell when no TA validation mechanisms are explicitly configured. In other embodiments, systems and methods are disclosed herein in which a timer serves a dual purpose. If the timer is set to infinity, a wireless device will always consider a TA to be valid within a given cell, and at the same time will disable other TA validation mechanisms. Otherwise, the wireless device will interpret the timer as indicating for how long the TA value that the wireless device possesses is considered to be valid. Benefits of the solutions described herein include reducing signaling bits in the configuration and avoiding the possibility of conflicting configurations.

Preconfigured uplink resources—configuration for TA validity in entire cell

A wireless device () obtains () a configuration of a set of periodic uplink resources specific for the device. The configuration configures the set of resources to support: a) a first procedure comprising a first Physical Uplink Shared Channel (PUSCH) transmission of a Message A (MsgA) transmission, b) a second procedure comprising uplink transmissions of, or corresponding to, a two-step Random Access Channel (RACH) procedure comprising, a first Physical Random Access Channel (PRACH) transmission and a second PUSCH transmission, and/or c) a third procedure comprising uplink transmissions of, or corresponding to, a four-step RACH procedure comprising a second PRACH transmission, and a third PUSCH transmission. A Timing Advance (TA) value of at least one of the transmissions is: i) independently configurable between the PUSCH and the PRACH transmissions, ii) configured to be zero, and the wireless device () refrains from validating the TA value, and/or iii) explicitly configured and validated before transmission from inactive or idle.

Wireless device, network node, and methods performed thereby, for handling uplink communication

Embodiments include methods implemented in a wireless device for efficient energy consumption at the wireless device. In one embodiment, a method comprises performing an uplink transmission on pre-configured resources to a network node; and monitoring in a search space (SS) window for an application layer response from a network node downlink transmission based on an offset value indicating a time difference between the SS window and the uplink transmission on the pre-configured resources.

Configurable starting position of search space window for uplink transmission on pre-configured resources

Techniques for facilitating dedicated transmissions over preconfigured uplink resources. Embodiments include techniques to configure subsequent PUR resource utilization (e.g., one-at-a-time basis or on a periodic basis), changes to EDT signaling to allow functioning with PUR, etc. An example method performed by a wireless device configured for use in a wireless communication network includes transmitting (), in an uplink message, a request for a configuration of preconfigured uplink resources. The method further includes receiving (), during a connected mode in which the wireless device has a connection with the wireless communication network, control signaling indicating a first preconfigured resource configuration that configures a first preconfigured resource. The method also includes transmitting or receiving () user data using the first preconfigured resource.

Support for transmission in preconfigured UL resources

Systems and methods are disclosed herein for Control Resource Set (CORESET) enhancements for initial access. In one embodiment, a method performed by a wireless communication device comprises receiving and decoding a Physical Downlink Control Channel (PDCCH) transmission in a CORESET in accordance with at least a portion of a Control Channel Element (CCE) to Resource Element Group (REG) mapping. The PDCCH transmission comprises one or more CCEs. The CCE to REG mapping comprises an interleaved portion that maps the one or more CCEs to a first set of REGs that are spread across a bandwidth of the CORESET, and a second portion that maps at least a portion of an additional CCE to at least a REG in a frequency gap between two REGs in the first set of REGs, the additional CCE corresponding to one of the CCEs mapped to the first set of REGs.

Coreset enhancement for reduced bandwidth UEs initial access

A method performed by a wireless device, UE, for configuring a semi-persistent scheduling, SPS is described. In accordance with the method, the UE may be configured to monitor a first search space of a physical downlink control channel for downlink control information, DCI, dedicated to the UE. The method may include receiving from the communication network SPS configuration data to configure a second search space to be monitored by the UE for DCI to activate or de-activate the SPS, the second search space being smaller than the first search space, and monitoring the second search space to detect the DCI to activate or de-activate the SPS. A corresponding method may be performed by a network node.

Activation and de-activation of semi-persistent scheduling

A wireless device determines whether to provide a reduced capability, RedCap, indication via a message 1 of a random access procedure. The wireless device transmits the message 1 based on the determination, and transmits a message 3 of the random access procedure. A RedCap indication is provided via the message 3 at least if a RedCap indication is not provided via the message 1. According to some embodiments, the wireless device receives an indication whether the wireless device is to provide a RedCap indication via the message 1, and the determination is based on the received indication. According to some embodiments, the indication whether the wireless device is to provide a RedCap indication via the message 1 is provided by whether a physical random access channel, PRACH, partition between RedCap wireless devices and other wireless devices is configured.
