Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE), including receiving, from a network entity, default bandwidth part (BWP) configuration information for a plurality of modes of operation of the network entity, the plurality of modes comprising a first mode and a second mode, and the default BWP configuration information indicating a first default BWP for the first mode and a second default BWP for the second mode; receiving, from the network entity, a mode indication indicating the network entity is operating in the first mode; and communicating with the network entity using the first default BWP based on receiving the mode indication and based on expiration of an inactivity timer.

Default bandwidth part (BWP) operation

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, downlink control information (DCI) that includes a dynamic primary cell (PCell) switch (DPS) field, wherein the DPS field indicates information associated with PCell switching for a group of UEs including the UE. The UE may determine whether to switch from a first PCell to a second PCell based at least in part on the DPS field in the DCI. Numerous other aspects are described.

Primary cell switching in accordance with downlink control information

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, information that indicates a periodic sequence of network energy saving (NES) states that are each associated with an antenna configuration of the network node. The UE may receive, from the network node during a current time period, one or more downlink transmissions using a maximum quantity of multiple input multiple output (MIMO) layers associated with an active NES state that is identified for a current time period based at least in part on the periodic sequence of NES states. Additionally or alternatively, the UE may transmit, to the network node during the current time period, one or more sounding reference signal (SRS) transmissions using an SRS antenna sounding configuration associated with the active NES state for the current time period. Numerous other aspects are provided.

Joint antenna adaptation in energy saving networks

A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a Physical Uplink Shared Channel (PUSCH) based on a configured grant that enables different configurations with multiple starting symbol occasions for the configured grants in new radio (NR) unlicensed communications. The PUSCH can be type A or as type B based on the configured grant. A number M of demodulation reference signals (DMRSs) and a number N of starting symbol occasions in a slot can be configured according to the configured grant, wherein M and N comprise an integer greater than zero, respectively.

Enabling multiple starting symbol occasions for configured grants in new radio (nr) systems operating on unlicensed spectrum

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a grant scheduling repetition-based system information block transmissions for the UE, the grant indicating a mapping configuration identifying time-frequency resources for a second repetition of a system information block transmission relative to a first repetition of the system information block transmission. The UE may receive, in a first subset bandwidth of a system bandwidth, the first repetition of the system information block transmission according to the grant. The UE may receive, in a second subset bandwidth of the system bandwidth, the second repetition of the system information block transmission according to the grant and based at least in part on the mapping configuration.

System information transmission with coverage recovery

Devices, systems and methods for a fifth generation (5G) or new radio (NR) system comprising determining a configuration for an uplink (UL) transmission resource with respect to a listen before talk (LBT) operation on an unlicensed spectrum and transmitting uplink control information (UCI) on the UL transmission resource based on the configuration subjected to the LBT operation.

Uplink (UL) transmission in wideband carrier and carrier aggregation in NR systems operating on unlicensed spectrum

Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process one or more configuration transmissions from the gNB carrying a rule for Uplink (UL) collisions and process a first Downlink (DL) transmission and a second DL transmission. The second circuitry may be operable to identify a first UL transmission for the first DL transmission and a second UL transmission for the second DL transmission, the first UL transmission overlapping with the second UL transmission in at least one Orthogonal Frequency Division Multiplexing (OFDM) symbol. The third circuitry may be operable to generate at least one of the first UL transmission and the second UL transmission in accordance with the rule for UL collisions.

Handling collision for mini-slot-based and slot-based transmission

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability of the UE to support a restricted bandwidth for data signaling. The UE may receive an indication of a bandwidth part for control signaling and an indication of a set of frequency domain resources for the data signaling. The set of frequency domain resources may correspond to a subset of the bandwidth part in accordance with the restricted bandwidth. The UE may communicate the control signaling over the bandwidth part and data signaling over the set of frequency domain resources. In some cases, the bandwidth restriction may correspond to a bandwidth size for the set of frequency domain resources or a number of resource blocks in the set of frequency domain resources.

Frequency resource allocation for reduced capability devices

Systems and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PD SCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.

UE paging in NR unlicensed spectrum

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a demodulation reference signal (DMRS) configuration for an uplink message that may indicate for the UE to refrain from including DMRS in at least a first portion of the uplink message based on the DMRS configuration. The UE may encode the uplink message without the DMRS in at least the first portion of the uplink message in accordance with the DMRS configuration. The UE may transmit the uplink message based on encoding the uplink message, and a network entity may receive and decode the uplink message. In some examples, the network entity may receive signaling that includes a set of uplink messages from different UEs. As such, the network entity may decode each, using a respective Reed-Muller (RM) code in accordance with a multi-user decoding algorithm.

Demodulation reference signal configuration for uplink messages

Systems and methods of in-sync/out-of-sync (IS/OOS) determination in the unlicensed band are described. Reference signals are measured on the unlicensed band. If the UE determines that at least one of the reference signals is missing, the IS/OOS condition is evaluated on that basis. If the missing signals are ignored when determining the IS/OOS condition, and the IS/OOS condition is unable to evaluated, the L1 sends an indication to the RRC layer. If the number of indications exceeds a threshold, the UE performs re-establishment or sends a report to the base station for adjustment of the reference signal resources. If the missing signals are counted, the missing signals are weighted based on proximity to the noise floor or a number of adjacent signals that are missing.

Radio link monitoring and failure for new radio-unlicensed operation

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a message that indicates a first initial uplink bandwidth part for use by the UE in communications with a network entity, the message also indicating a plurality of random access occasions, at least one of the plurality of random access occasions being in frequency resources that are outside of the first initial uplink bandwidth part. The UE may select a random access occasion of the plurality of random access occasions for transmission of a random access preamble from the UE to the network entity. The UE may transmit, as part of a random access procedure, the random access preamble within the random access occasion.
