A user equipment (UE) is configured to perform channel estimation. The UE operates in a current channel estimation mode comprising either one of a first mode or a second mode, wherein the first mode comprises receiving first reference signals (RS) having a first RS overhead and wherein the second mode comprises receiving second reference signals (RS) having a second RS overhead, receives a network indication to switch from the current channel estimation mode to a new channel estimation mode comprising the other one of the first mode or second mode, transmits an acknowledgment to the network that the network indication was received and switches from the current channel estimation mode to the new channel estimation mode in accordance with the network indication.

Channel estimation using artificial intelligence

Various manners of reporting channel state information (CSI) measurements in a multiple transmission and reception point (multi-TRP) configuration are provided. A UE may perform channel state information (CSI) measurements for a channel measurement resource (CMR) for the first gNB and at least one interference measurement resource (IMR) for the at least one second gNB, determine a configuration for a CSI report for the CSI measurements including a channel quality indicator (CQI) measurement for the CMR and the at least one IMR and transmit the CSI report to at least one of the first gNB and the at least one second gNB.

Channel state information report for multi-TRP operation

Enhanced channel state information (CSI) reporting may include encoding a CSI reporting configuration associated with a first transmission and reception point (TRP) and a second TRP. The CSI reporting configuration may include at least one codebook configuration. The at least one codebook may include at least one of a rank restriction configuration or a codebook subset restriction (CBSR) configuration. The at least one of the rank restriction configuration or the CBSR configuration may correspond to at least one of a particular type of TRP measurement, a particular TRP of the first TRP or the second TRP, or channel measurement resources (CMRs) associated with at least one of the first TRP or the second TRP. A CSI measurement communication received from a user equipment (UE) may be decoded. The CSI measurement communication may be based on the decoded CSI reporting configuration.

Enhanced CSI reporting for multi-TRP operation

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

Systems and methods provide a channel state information (CSI) measurement based on measuring a demodulation reference signal (DMRS) for a physical downlink shared channel (PDSCH) transmission. A user equipment (UE) triggers measuring of a CSI reference signal (CSI-RS) from a base station. The UE triggers measuring of a DMRS for a PDSCH transmission from the base station. The UE generates a CSI report to report the CSI measurement, based on both the CSI-RS and the DMRS for the PDSCH transmission. The UE may then send the CSI report to report the CSI measurement to the base station.

Systems and methods for PDSCH based CSI measurement

Apparatuses, systems, and methods for a wireless device and a cellular base station to support common analog beam steering for band groups. The wireless device may provide an indication of analog beam steering capability of the wireless device to the cellular base station. For example, the wireless device may support a limited number of analog beams for each of one or more band groups. The cellular base station may select beam configuration information for the wireless device based at least in part on the indication of analog beam steering capability of the wireless device. This may include selecting a common beam for multiple component carriers for the wireless device based on the wireless device's analog beam steering capability. The cellular base station may provide the beam configuration information to the wireless device.

Common analog beam steering for band groups

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

Methods, systems, and devices for wireless communications are described. SSB based inter-frequency measurements may include configuring a UE to perform inter-frequency measurements without measurement gap within a measurement window, and applying scheduling restrictions to prioritize the inter-frequency measurements over uplink transmissions within the measurement window. The measurement window includes an SMTC window duration. Measurement resource sharing or restriction is described for SSB based inter-frequency measurement objects without measurement gap.

Methods and apparatus for scheduling availability/restriction and measurement sharing for SSB based inter-frequency measurement without measurement gap

A user equipment (UE) is configured to receive a sounding reference signal (SRS) configuration from a network, wherein the SRS configuration comprises a 6 port SRS configuration. The UE is also configured to transmit, from each of the 6 ports, SRS on one or more SRS resources corresponding to the SRS configuration.

Codebook and non-codebook support for SRS with 6 ports

This disclosure relates to techniques for performing multi-transmission and reception point operation in a wireless communication system. A transmission control indication state may be indicated for future monitoring of a control channel, e.g., using one or more rules. The indicated state may be used to provide and receive control information for performing multi-transmission and reception point operation.

Mapping unified transmission states for multipoint control channel reception using rules

To extend a physical broadcast channel (PBCH) in wireless communications, an extended physical broadcast channel (EPBCH) transmission is generated with one or more legacy PBCH blocks and one or more EPBCH blocks within an extension window. A size of the extension window is determined based at least in part on a PBCH repetition number and a number of the legacy PBCH blocks relative to a number of the EPBCH blocks. The EPBCH transmission is transmitted by a base station (BS) to one or more user equipment (UE).

Physical broadcast channel extension in wireless communications

A user equipment (UE) reports channel state information for multiple transmission reception points (TRPs) to a network. The UE collects channel state information (CSI) corresponding to multiple transmission reception points (TRPs), receives a signal configured to trigger a semi-persistent CSI (SP-CSI) report from a first TRP of the multiple TRPs, generates a SP-CSI report that includes CSI corresponding to each TRP of the multiple TRPs and transmits the SP-CSI report to a cell associated with the multiple TRPs.

Reporting channel state information for multi-TRP operation

Systems and methods for user equipment (UE) capable of performing sidelink (SL) communications that account for overlapped SL resource pools of multiple radio access technologies (RATs) are disclosed. A UE may select, based on prioritizing non-overlapped resources over overlapped resources, one or more candidate resources and/or one or more transmission resources; may determine a power control configuration without considering SL pathloss corresponding to a first RAT when a second power control configuration determination for a second RAT does not consider SL pathloss; may select physical sidelink feedback channel (PSFCH) locations for PSFCH use from first PSFCH locations of resources of a first SL resource pool on a first RAT that do not overlap with a second SL resource pool on a second RAT according to a bitmap; and/or may select one of a PSFCH transmission and PSFCH reception using a data priority rule and/or a pool sharing rule.

Resource allocation for co-channel coexistence

A method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device that specifies PDCCH monitoring for one subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs) that are related to a spectrum in 5G new radio (NR) above 52.6 GHz are described. In one embodiment, the monitoring limits associated with each of the SCSs are applied per slot per CC and the user equipment (UE) decode complexity associated with performing the monitoring limits for the different SCSs in the group is equal. In one embodiment, the monitoring limits associated with each of the SCSs are for a slot group of a plurality of slots and are for application over a duration of the slot group.

System and methods for PDCCH monitoring in new radio

Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.
