Abstract: One or more wireless devices may communicate with a base station in a wireless network, such as a terrestrial network or a non-terrestrial network. The one or more wireless devices may resume control channel monitoring after a timing gap from an uplink signal transmission. One or more configuration parameters, such as radio resource control configuration parameters, may configure the one or more wireless devices to determine when and/or whether to resume the control channel monitoring after sending an uplink signal.

Abstract: A wireless device comprises one or more processors and memory storing instructions. When executed by the one or more processors, the instructions cause the wireless device to receive one or more configuration parameters, for a non-terrestrial network (NTN), indicating candidate timing advance (TA) values for a first cell of cells. The instructions cause the wireless device to transmit, via the first cell, a preamble using a TA value selected from the candidate TA values based on one or more measurement power values of reference signals of the cells.

Abstract: A wireless device may communicate with a base station via a primary cell (PCell) and one or more secondary cells. A plurality of types of handovers, such as a layer 1/layer 2 triggered handover or a conditional handover, may be indicated to the wireless device for switching its PCell. One or more conditions, such as a priority associated with a handover type, may be used to determine which type of handover to perform.

Abstract: A wireless device receives one or more configuration parameters indicating a first timer used for prohibiting initiation of a random access (RA) procedure for a buffer status report (BSR). The wireless device starts the first timer based on completing a first RA procedure initiated for a first BSR and triggers a second BSR while the first timer is running. Based on the triggering the second BSR while the first timer running, the wireless device prohibits initiation of a second RA procedure for the second BSR.

Abstract: One or more wireless devices may determine whether to initiate repetition of a transmission, based on characteristics of communications link, such as in a non-terrestrial network (NTN). Characteristics of the communications link may comprise, for example, distance/length, propagation delay, elevation angle, and/or reference signal received power (RSRP). Different random access resources may be used to indicate whether repetition is initiated.

Abstract: A method may include receiving, by a wireless device, one or more configuration parameters for a timing advance (TA) reporting procedure. The one or more configuration parameters may include a first timing advance threshold for a TA reporting based on an offset between a current timing advance value and a last reported timing advance value. The method may also include triggering the TA reporting procedure based on a condition for the first timing advance threshold being satisfied. The method may additionally include based on the triggering the TA reporting procedure, triggering a scheduling request (SR) and starting a SR prohibit timer. The method may further include, in response to canceling the TA reporting procedure, cancelling the triggered SR and stopping the SR prohibit timer.

Abstract: A wireless device receives configuration parameters indicating: transmission of an uplink (UL) signal in a set of symbols, and a plurality of physical downlink control channel (PDCCH) monitoring occasions (MOs) for repetitions of a downlink control information (DCI). At least one PDCCH MO of the plurality of PDCCH MOs overlaps in time with the set of symbols. Based on a quantity of the at least one PDCCH MO, the wireless device cancels the transmission of the UL signal in a subset of symbols from the set of symbols or not monitor (e.g., skip monitoring) the at least one PDCCH MO.

Abstract: A bandwidth for transmission of wireless communications may be reduced, such as for energy saving. Downlink control information (DCI) may be used to indicate the bandwidth reduction, such as dynamic bandwidth part reduction. A base station may adjust transmission of periodic reference signals (RSs) using the reduced bandwidth after the DCI is sent, which may provide advantages such as improved accuracy and/or reliability of operations, such as channel state information (CSI) and/or beam measurement.

Abstract: A wireless device receives a packet corresponding to a hybrid automatic repeat request (HARQ) process, wherein the packet comprises a medium access control (MAC) control element (CE). Based on whether a feedback of the HARQ process being enabled or disabled, the wireless device applies the MAC CE after at least one of: a first time duration starting from transmission of feedback of the packet; or a second time duration starting from reception of the packet.

Abstract: A wireless device may communicate with a base station for reporting measurements of reference signals associated with one or more beams. The wireless device may use one or more adjusted configuration parameters, for example, if the base station reduces its transmission power. The wireless device may report one or more cell and/or beam measurements based on the one or more adjusted configuration parameters, which may provide improved accuracy of measurement reporting.

Abstract: A wireless device receives a downlink control information (DCI) scheduling a transport block. The wireless device starts a first discontinuous reception (DRX) timer based on the receiving the DCI. The wireless device stops the first DRX timer based on: the transport block not being successfully decoded and the DCI indicating stopping of the first DRX timer.

Abstract: A wireless device receives one or more configuration parameters indicating: a discontinuous reception (DRX) operation and to transmit a report at a first symbol. The wireless device transmits the report at the first symbol based on a second symbol being in an active time of the DRX operation, where the second symbol occurs a number of symbols prior to the first symbol, and the number of symbols is determined based on an open-loop timing advance (TA) value.

Abstract: Downlink signals, such as synchronization signals and/or reference signals, may be used for facilitating communications between communication devices. The downlink signals may be dynamically reconfigured, for reduced resource consumption, using control channel signaling with reduced resource overhead. Reconfiguration of downlink signals may be based on determined traffic volume in the communication network to minimize any impact of the reconfiguration on network performance.

Abstract: A wireless device receives one or more configuration parameters indicating a single value for a contention resolution timer. The wireless device starts the contention resolution timer based on an initial transmission of a transport block of a random access (RA) procedure via a non-terrestrial network, where a length of the contention resolution timer is initialized equal to the single value. The wireless device receives, while the contention resolution timer is running, a first downlink control information (DCI) indicating a retransmission of the transport block. In response to the contention resolution timer expiring and the receiving the first DCI during the contention resolution timer, the wireless device does not discard a temporary cell (TC) radio network temporary identifier (RNTI) of the wireless device, where the expiry of the contention resolution timer is prior to the retransmission of the transport block.

Abstract: A wireless device receives one or more configuration parameters indicating one or more radio network temporary identifiers (RNTIs) to monitor, via downlink control channels, during an active time of DRX operation. The wireless device selects, for transmission of a message-A of a random access procedure, one or more resources, where the message-A comprises a preamble and a payload and the payload comprises a C-RNTI. The wireless device starts a response window based on transmitting the preamble via at least one resource of the one or more resources. Based on dropping transmission of the payload and during the response window, the wireless device monitors the downlink control channels for a first RNTI, where the first RNTI is associated with a response to the preamble and determined based on the at least one resource, and does not monitor the downlink control channels for the one or more RNTIs.

Abstract: Timing advance (TA) reporting may be used in wireless communications. TA reporting information may be provided by a wireless device to align timing between the wireless device and a base station, such as in a non-terrestrial network. TA reporting information may be sent via a scheduling report (SR) procedure, a buffer status report (BSR) procedure, and/or a random access (RA) procedure. To avoid unnecessary transmissions of TA reporting information, TA reporting may be canceled based on one or more of a receipt of a timing offset and/or an expiration of a timer.

Abstract: In response to initiating a two-step random access (RA) procedure, a wireless device selects a first radio resource for transmission of a first message of the two-step RA procedure. Based on the first radio resource being invalid for the transmission of the first message, the wireless device switches from the two-step RA procedure to a four-step RA procedure and transmits, via a second radio resource, a preamble for the four-step RA procedure.

Abstract: A wireless device selects, in response to initiating a random access procedure, a first radio resource for transmitting a message. In response to determining the first radio resource is invalid for transmission of the message, the wireless device transmits, via a second radio resource, the message based on determining the second radio resource is valid for the transmission of the message and determining a time difference between the second radio resource and the first radio resource is smaller than a threshold.

Abstract: A wireless device receives a first downlink control information (DCI) that schedules a reception of a transport block and indicates a hybrid automatic request (HARQ) process number with feedback disabled. The wireless device receives a second DCI that schedules a retransmission of the transport block and indicates the HARQ process number with feedback disabled, where the retransmission of the transport block overlaps in time with at least one symbol of a transmission of an uplink signal. Based on successfully decoding the transport block scheduled by the first DCI, the wireless device drops the retransmission of the transport block scheduled by the second DCI and transmits the uplink signal.

Abstract: A media access control (MAC) layer of a wireless device sends a first indication indicating transmission of a scheduling request (SR) to a physical layer of the wireless device. The MAC layer receives from the physical layer a second indication indicating the SR is being dropped. In some cases, the MAC layer may receive one or more SR configuration parameters indicating at least one of: an SR prohibit timer; a maximum SR transmission counter; or one or more physical uplink control channel (PUCCH) resources. Based on the receiving the second indication, the MAC layer stops the SR prohibit timer and decrements an SR counter.
