The disclosure relates to Discontinuous Reception (DRX) based UE behavior. A user equipment (UE) is configured to perform operations comprising: obtaining a first DRX cycle; determining a second DRX cycle at least based on the first DRX cycle and a DRX cycle threshold, wherein the DRX cycle threshold is a highest value of DRX cycle that can support LEO (Low-Earth Orbit) cell measurement; and applying the second DRX cycle, comprising applying the second DRX cycle to measurement of at least one LEO cell of the serving cell and a neighbor cell, wherein at least one of the serving cell and the neighbor cell is a LEO cell.

DRX based UE behavior

Provided is a method for a base station, includes: generating, for transmission to at least one UE, control information associated with SRS transmission, wherein the control information indicates an SRS band including a plurality of RBs for the SRS transmission, the control information indicates a first subband for a first UE and a second subband for a second UE in a same SRS band for an SRS transmission occasion; receiving, from the at least one UE, SRS on a plurality of SRS transmission occasions according to the control information, wherein a location hopping parameter is applied to the plurality of SRS transmission occasions, wherein a first starting location of the first subband for the first UE on a first SRS transmission occasion and a second starting location of the first subband for the first UE on a second SRS transmission occasion are determined based on the location hopping parameter.

Frequency hopping enhancement for partial frequency sounding

In an example method, a user equipment (UE) device receives a plurality of Synchronization Signal Block (SSB) beams transmitted by base stations (BSes) during discovery burst transmission windows (DBTWs). For each of the SSB beams, the UE device determines an index value of the SSB beam (l) within a respective one of the DBTWs, and determines a value Z=lmod N, where Nrepresents a maximum allowable number of SSB beams transmitted by each of the BSes during a single DBTW. The UE device determines whether two or more of the SSB beams are quasi co-located based on the values Z for the SSB beams, and processes wireless signals received from the BSes based on the determination.

Technologies in multi-PDSCH transmission in a wireless network

The present application relates to devices and components including apparatus, systems, and methods for determining and acknowledging transmission configuration indicator states.

Transmission configuration indicator determination and acknowledgment

A cell performs beam management operations for a user equipment (UE). The cell transmits a first group of multiple reference signals via a first transmission reception point (TRP) to a user equipment (UE), transmits a second group of multiple reference signals via a second different TRP to the UE, receives an indication that the UE has selected a first beam associated with one of the multiple reference signals of the first group and a second beam associated with one of the multiple reference signals of the second group and transmits downlink data to the UE using the first beam and the second beam.

Beam management in multi-TRP operation

Configuring channel state information reference signal (CSI-RS) reporting at a network may include encoding a single CSI-RS reporting configuration for transmission to a user equipment (UE) that is in connected mode with both a first transmission and reception point (TRP) and a second TRP. The single CSI-RS reporting configuration may include a plurality of CSI-RS resource sets. Each of the plurality of CSI-RS resource sets may include a plurality of CSI-RS resources. At least one of the plurality of CSI-RS resource sets may include CSI-RS resources that correspond to the first TRP or the second TRP. A CSI measurement communication received from the UE may be decoded. The CSI measurement communication may be based on the single CSI-RS reporting configuration communication. Based on the CSI measurement communication, one or more downlink data transmissions may be scheduled.

CMR and IMR configuration enhancement for multi-TRP CSI-RS reporting

A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

Full power uplink transmission enhancement

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for communications between user equipment. One of the methods includes receiving, by a first device and from a second device, sidelink control information indicating a resource reservation for a single-slot resource for the second device to use to communicate with the first device; determining, by the first device and based at least in part on the sidelink control information, whether a potential resource collision exists when the first device is scheduled to communicate with another device using the single-slot resource or when the single-slot resource is reserved by another device; and in response to determining that the potential resource collision exists, sending, by the first device and within a predetermined number of slots from a reference slot, a collision message to cause the second device to determine another single-slot resource to use to communicate with the first device.

Inter-device communication

Aspects are described for a user equipment (UE) comprising a transceiver and a processor communicatively coupled to the transceiver. The UE is in a multi-TRP mode. The processor is configured to receive a configuration message, a BFD configuration, and a BFR configuration. The UE switches to a single-TRP mode upon receiving the configuration message. The processor is further configured to update a first BFD procedure based on the BFD configuration and update a first BFR procedure based on the BFR configuration. Finally, the processor is configured to perform the updated first BFD procedure and the updated first BFR procedure for the first TRP responsive to a result of the updated first BFD procedure.

Method for a transmission/reception point (TRP) specific beam failure recovery (BFR) for a single downlink control information (DCI) mode

This disclosure relates to techniques for performing channel state information reporting for multi-transmission-reception-point operation in a wireless communication system. Channel state information configuration information may be provided to a wireless device. The channel state information configuration information may indicate channel measurement resources associated with each of multiple transmission reception points. The wireless device may perform channel state information reporting based on the channel state information configuration information.

Channel state information reporting for multi-transmission-reception-point operation

The present application relates to devices and components including apparatus, systems, and methods to implement a codebook design for Doppler cases. For example, a multiple-input, multiple-output code configuration may be utilized for selecting components.

Codebook design

Uplink transmissions of a mobile device (UE) may be improved in a number of ways. Uplink Transmission Time Interval (TTI) bundling, including both Type-A and Type B PUSCH repetitions, may be implemented with variable TTI bundle sizing. The TTI bundle size may be determined by a base station and communicated to the UE explicitly, or may be determined by the UE implicitly, based on an indicated repetition number and frequency hopping number. The UE may also report frequency hopping (FH) assist information to the base station for use by the base station to more efficiently configure FH for the uplink transmissions. Finally, the UE may use (or maintain) the same transmission power, for each TTI transmit occasion of the same TTI bundle in order to improve (cross-slot) channel estimation accuracy. Power allocation may be prioritized to ensure that at the same time a total power for the uplink transmissions of the UE does not exceed a specified threshold.

Enhanced physical uplink shared channel transmission in wireless communications

Techniques for power savings by a wireless device. The technique including determining, by a first wireless device, a sidelink resources pool including a set of sidelink resources for communicating directly with a second wireless device; determining one or more reservation periods associated with resources of the sidelink resources pool; determining a number of sensing occasions based on the one or more reservation periods; sensing a wireless medium within the sidelink resources pool based on the determined number of sensing occasions and the determined one or more reservation periods; selecting a set of candidate resources from the sidelink resources pool based on the sensing; and transmitting data to the second wireless device based on the selected set of candidate resources.

Enhanced sidelink sensing and resource allocation

A user equipment (UE) configured to receive secondary cell (SCell) activation configuration information from a first cell, receive a medium access control (MAC) control element (CE) from the first cell, wherein the MAC CE indicates that a SCell state is to be changed from a deactivated state to an activated state and receive aperiodic reference signals from a secondary cell (SCell), wherein the reception of the aperiodic reference signals is triggered by the MAC CE.

Fast secondary cell activation with temporary reference signals

In sidelink carrier aggregation, a first user equipment (UE) transmits data packets to a second UE using a plurality of carriers. The second UE transmits Hybrid Automatic Repeat Request (HARQ) ACK/NACK information for the data packets to the first UE via one or more Physical Sidelink Feedback Channels (PSFCHs). The aggregated carriers may be constrained to have the same PSFCH configuration, or not. Resource selection for PSSCH transmission may be performed by considering scheduled PSFCH so as to conform to transmit capability limitations and/or a half-duplex limitation of the first UE and/or the second UE. The PSFCH may be transmitted on a single carrier of said plurality, but include joint HARQ feedback for each of the carriers. Furthermore, HARQ feedback may be transmitted on a Physical Sidelink Shared Channel (PSSCHs), being signaled by the receive UE (i.e., the UE that transmits the feedback) via sidelink control information (SCI).
