Apparatuses, systems, and methods for providing downlink control for non-coherent joint transmission. A cellular base station may provide downlink control information associated with a non-coherent joint transmission downlink data communication to a wireless device, which may receive the downlink control information. The downlink control information may be provided as a single downlink control information including scheduling information for two data streams of the non-coherent joint transmission data communication, or a portion of a multi-stage downlink control information transmission. The wireless device may receive the non-coherent joint transmission downlink data communication based at least in part on the downlink control information.

Downlink control for non-coherent joint transmission

Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for Fifth Generation New Radio (5G NR) frequency range two (FR2) based communications beam management. The UE may configure, via communications with a base station, serving the UE, a group ID for PUCCH resources within a group of PUCCHs, e.g., for FR2 based communications. The UE may receive, from the base station, an update to one or more PUCCH resources within the group of PUCCHs via a medium access control (MAC) control element (CE) that may include one of a resource ID indicating an update to a PUCCH resource or the group ID to update the group of PUCCH resources. The UE may update, based on the MAC-CE, the one or more PUCCH resources within the group of PUCCHs.

5G NR FR2 beam management enhancements

A wireless device may comprise antennas and a processor configured to cause the wireless device to determine preferred antenna ports for at least one primary component carriers (PCCs) and at least one secondary component carriers (SCCs) based on performed downlink measurements of antenna ports. The wireless device may further determine support capabilities of the wireless device and perform computations using additional measurements of the antenna ports. Based on the computations, the wireless device may assign the preferred antenna ports to the PCCs and SCCs and perform uplink transmission using the assigned antenna ports.

Uplink carrier aggregation antenna contention resolution

A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.

Reporting framework for dynamic UE capabilities

Apparatuses, systems, and methods for a user equipment device (UE) to perform multiple TTI PUSCH transmissions in a wireless communication system as well as code block groups (CBGs) based retransmissions operations. A UE may perform radio resource control (RRC) signaling with a network entity to configure a data structure that may include one or more sets of physical uplink shared channel (PUSCH) transmission configurations, where each set of PUSCH transmission configurations span multiple TTIs. The wireless device may be configured to receive, from the network entity, a downlink control information (DCI) message that may include a time domain resource assignment field (TDRA) that may indicate a set of PUSCH transmission configurations included in the data structure. The wireless device may perform PUSCH transmissions spanning multiple TTIs according to the indicated set of PUSCH transmission configurations over an unlicensed band.

Multiple TTI PUSCH transmissions in a wireless communication system

Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.

SRS-switching enhancements for mitigating the impact of conflict and blanking

Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Methods and systems for downlink transmission and interlace uplink transmission

A device may wirelessly communicate with a number of different cells used in a carrier aggregation. The device may monitor physical downlink control channels (PDCCHs) on the different cells, dynamically switching between a dormant monitoring state (DS) and an active monitoring state (AS). In the DS, the UE may not monitor any PDCCH candidates on the active secondary SCells corresponding to the DS, or it may monitor PDCCH candidates in the search space (SS) set with the largest monitoring periodicity among the multiple SS sets on the active bandwidth part (BWP). In the AS, the UE may monitor a set of PDCCH candidates in physical resources configured by higher layers on the BWPs. Switching from one monitoring state to another may be facilitated through the use of a new downlink control information (DCI) format without data scheduling, a modified existing DCI format with data scheduling, and/or use of a DS timer.

Flexible downlink control signal monitoring in wireless communications

In an example method, a user equipment (UE) device determines one or more component carriers available to the UE device for at least one of transmitting or receiving data over a wireless network. The UE device transmits, to the wireless network, for each component carrier, an indication whether the component carrier supports at least one of transmitting or receiving data according to a multi-transmission and receiving points (multi-TRP) communication protocol.

Multi-transmission and receipt point (multi-TRP) enhancement

Various systems and methods disclosed herein describe improvements for beam management that leverage virtualization across a vertical polarization (V-Pol) and horizontal polarization (H-Pol). One or more of a user equipment (UE) and a base station may include an antenna array comprising both V-Pol and H-Pol antenna elements. A UE may message a base station to configure uplink (UL) multiple input multiple output (MIMO) operations across one or more of the V-Pol and the H-Pol. The message may include a number of MIMO layers to be concurrently used for communicating data to the base station, where each MIMO layer is transmitted using one of a V-Pol and an H-Pol; a number of sounding reference signals (SRS) to be transmitted by the UE, each SRS to be transmitted using one of the V-Pol and the H-Pol; and a supported maximum number of antenna ports per each SRS.

Wireless communication systems and methods using virtualization across a horizontal and/or vertical polarization

A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.

Transmission power management for concurrent operating radios

Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.
