Abstract: A wireless device receives, from a base station, one or more configuration messages comprising a plurality of sidelink feedback resources via one of a system information block or a radio resource control message. A determination is made, based on a received signal power from the base station, a sidelink feedback resource of the plurality of sidelink feedback resources. A sidelink feedback signal is transmitted, to a second wireless device, via the sidelink feedback resource.

Abstract: Wireless communications may be used to support data processing. A plurality of resources may be indicated for a wireless device to use to communicate and/or process data. Data may be received and processed based on groups of the plurality of resources to be used. For example, the plurality of resources to be used may be associated with different resource groups.

Abstract: A wireless device receives indications of: a first scheduling request (SR) resource corresponding to first logical channel(s) having a first logical channel prioritization (LCP) mapping to first radio resources; and a second SR resource corresponding to second logical channel(s) having a second LCP mapping to second radio resources. A buffer status report (BSR) is triggered in response to data becoming available for the second logical channel(s). First uplink grant(s) indicating a first radio resource of the first radio resources is received. An SR for transmission of the BSR is triggered in response to the first radio resource not meeting the second LCP mapping configured for the second logical channel(s) that triggered the BSR. The SR is transmitted via the second SR resource selected based on the second logical channel(s) triggering the BSR. The BSR is transmitted via a second radio resource of the second radio resources.

Abstract: An access and mobility management function (AMF) receives a registration request for a wireless device. The AMF sends, to a network repository function (NRF) and in response to the registration request, a discovery request for an address of a session management function (SMF). The discovery request comprises network slice isolation information for at least one network slice. The AMF receives, from the NRF and based on the discover request, a discovery response comprising the address of the SMF. The AMF sends, to the SMF, a session create request to create a session for the wireless device.

Abstract: Wireless communications using multiple active resources (e.g., bandwidth parts (BWPs)) are described. A wireless device may perform failure event detection, such as radio link monitoring (RLM) and/or beam failure detection (BFD), jointly or separately for multiple active resources (e.g., BWPs) based on one or more criteria.

Abstract: A user plane function receives, from a session management function, a request for at least one quality of service (QoS) report for a data flow, the request indicating: a QoS event; and a first QoS value for the QoS event. Monitoring packets for monitoring a second QoS value of the data flow are sent to a base station. A determination is made of an occurrence of the QoS event based on the second QoS value and the first QoS value. An indication of the occurrence is sent to the session management function.

Abstract: A wireless device receives configuration parameters comprising: a monitoring periodicity; and a first parameter indicating one or more symbols. A downlink control channel is monitored for a downlink control information indicating a slot format of an active bandwidth part. The monitoring is during at least one monitoring symbol determined based on the monitoring periodicity and the first parameter. The downlink control information comprising one or more fields indicating the slot format is received. One or more transport blocks in one or more uplink symbols determined based on a first slot format is transmitted via the active bandwidth part.

Abstract: A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups. The cells are in the same timing advance group. A first sounding reference signal (SRS) is transmitted via a first cell of a first PUCCH group in parallel with transmission of a first PUCCH via a second cell of a second PUCCH group. In response to a second PUCCH being transmitted via the first cell in parallel with a configured transmission of a second SRS, the configured transmission of the second SRS via the first cell is dropped.

Abstract: A session management function (SMF) receives, from an access and mobility management function (AMF), a first request to establish a first session for a wireless device. The first request comprises a cellular internet-of-things (IoT) optimization indication for transfer of data of cellular IoT over a control plane. A second request to establish a second session between the SMF and the UPF is sent to a user plane function (UPF). The data for cellular IoT is received from the UPF via the second session. The data is sent to the AMF via the first session.

The base station distributed unit transmits the one or more first configuration parameters and the one or more second configuration parameters.

Abstract: A base station transmits a radio resource control message. The radio resource control message comprises a periodicity parameter indicating a number of symbols for a periodic resource allocation. A downlink control information indicating activation of the periodic resource allocation is transmitted. The downlink control information comprises one or more fields indicating a numerology. The numerology indicates a symbol duration. Transport blocks are received via resources associated with the periodic resource allocation. A time interval between two subsequent transmission occasions of the periodic resource allocation is determined based on the symbol duration and the number of symbols.

Abstract: A wireless device receives configuration parameters of a cell comprising: a first bandwidth part; and a second bandwidth part. A downlink control information is received. The downlink control information indicates: a priority of a transport block; and a hybrid automatic repeat request (HARQ) feedback timing of a HARQ feedback of the transport block. After receiving the downlink control information (DCI) and before the HARQ feedback timing, the active bandwidth part is switched from the first bandwidth part to the second bandwidth part. The HARQ feedback is transmitted in response to the priority of the transport block being associated with a first service type.

The cell configuration parameters indicate: at least one first information element (IE) indicating a first identifier of a first cell of the one or more cells; at least one second IE indicating that the first cell is an unlicensed cell; and at least one third IE indicating one or more configuration parameters of radio resources of the unlicensed cell. The first base station sends, to the second base station, a handover request message for a wireless device based on the cell configuration parameters.

Abstract: A wireless device receives a first downlink control information indicating a grant for transmission of one or more first transport blocks via a first bandwidth part during a transmission time. The first downlink control information indicates the transmission time. A second downlink control information indicating switching from the first bandwidth part to a second bandwidth part at a switching time is received. A switch is performed, at the switching time, from the first bandwidth part to the second bandwidth part as an active bandwidth part in response to the second downlink control information. The grant indicated by the first downlink control information is ignored in response to the switching time of the switch being earlier than the transmission time indicated by the first downlink control information.

Abstract: A wireless device receives configuration parameters of a beam failure recovery (BFR) procedure. The configuration parameters indicate: a first time value of a BFR time window; and a second time value of a response window. Beam failure instances are detected. A preamble associated with a reference signal is transmitted. During the response window after the transmission of the preamble, a downlink control channel is monitored for a response to the preamble. The wireless device stops monitoring the downlink control channel in response to not receiving the response during the BFR time window after the detecting the beam failure instances.
