DETAILED DESCRIPTION

In some deployments, wireless communications systems may operate in millimeter wave (mmW) frequency ranges (e.g., 24 gigahertz (GHz), 26 GHz, 28 GHz, 39 GHz, 52.6-71 GHz, 71-114.25 GHz, among other examples). Wireless communications at these frequencies may be associated with increased signal attenuation (e.g., path loss, penetration loss, blockage loss), which may be influenced by various factors, such as diffraction, propagation environment, density of blockages, material properties, etc. Due to the increased amount of path, penetration and blockage losses in mmW communications systems, transmissions between wireless devices (e.g., from a base station and/or a user equipment (UE)) may be beamformed to coherently combine energy and overcome the path losses at these frequencies. Additionally, a receiving device may use beamforming techniques to configure one or more antennas, which may be included in an antenna array or an antenna array module, such that transmissions are received in a directional manner.

In some deployments, communications in mmW frequencies may utilize what is referred to as frequency range 2 (FR2), corresponding to deployments in the 24.25-52.6 GHz range (e.g., 24 GHz, 26 GHz, 28 GHz, 39 GHz, etc.). As demand for wireless communications increases, additional mmW frequencies may be desirable for some deployments, such as frequency range 4 (FR4) (e.g., upper mmW bands) which may be associated with 52.6 GHz, and beyond. In some deployments, wireless devices may use antenna modules that include a number of antenna elements or different subarrays.

A UE may communicate with a base station using beamformed transmissions. In some cases, a base station may configure the UE to communicate using a dynamic beam (e.g., a composite beam) that incorporates multiple individual directional beams to improve communications reliability or a communications rate. The UE may report a set of preferred beams to a base station, and the base station may select one or more of the preferred beams to generate the dynamic beam. In some cases, the UE may identify preferred beams based on reference signal quality. It may be beneficial for the UE to measure and indicate to the base station which beams may be suitable for combining to generate a dynamic beam.

According to the techniques described herein, a UE may be configured to measure and report a beam combination parameter to a base station to improve generation of a dynamic beam for beamformed communications. In some examples, the UE may measure the beam combination parameter in terms of angular spread/coverage area of individual beams, array or signal gains at antennas or panels of the UE, additional panel/antenna module related information, etc. Based on the reported beam combination, the base station may generate the dynamic beam and indicate a beam configuration to the UE for subsequent communications. In some examples, distinct beam combination parameters may be reported for each component carrier or subband in a carrier aggregation (CA) configuration (e.g., inter-band CA or intra-band CA, either in a single frequency range or across multiple frequency ranges).

In some examples, the base station may generate the dynamic beam by determining a power delay profile for the dynamic beam, or by determining timing and frequency offsets for the dynamic beam to combine the individual beams in phase. The base station may identify which beams the UE is to use for the dynamic beam, and the UE may use the individual beam information to compute the offsets or determine the profile.

Aspects of the disclosure are initially described in the context of wireless communications systems. An example beamforming configuration and an example process flow are then described. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to techniques for beamforming enhancement and feedback.

According to the techniques described herein, a UE115may be configured to measure and report a beam combination parameter to a base station105to improve generation of a dynamic beam for beamformed communications. In some examples, the UE115may measure the beam combination parameter in terms of angular spread/coverage area of individual beams, array or signal gains at antennas or panels of the UE115, additional panel/antenna module related information, etc. Based on the reported beam combination, the base station105may generate the dynamic beam and indicate a beam configuration to the UE115for subsequent communications. In some examples, distinct beam combination parameters may be reported for each component carrier or subband in a CA configuration.

FIG.2illustrates an example of a wireless communications system200that supports techniques for beamforming enhancement and feedback in accordance with aspects of the present disclosure. In some examples, the wireless communications system200may implement aspects of wireless communications system100. For example, the wireless communications system200may include a base station205and UEs215, which may be examples of the corresponding devices described with reference toFIG.1. The wireless communications system200may include features for improved communications between the UE215and the base station205, among other benefits.

The base station205may communicate with the UE215using beamforming techniques. For example, the base station205and the UE215may communicate with one another via one or more base station beams225and one or more UE beams220. Individual base station beams225may correspond to individual UE beams220for communications in the wireless communications system200. In some examples, the communications illustrated inFIG.2may include downlink transmissions to the UE215, where the base station beams225may be transmission beams and the UE beams220may be reception beams. Additionally or alternatively, the communications illustrated inFIG.2may include uplink transmissions from the UE215, where the base station beams225may be reception beams and the UE beams220may be transmission beams.

In some examples, a base station205may configure a dynamic beam (e.g., a composite beam) to improve a communications reliability or rate with the UE215. The dynamic beam may include one or more base station beams225or one or more UE beams220. The dynamic beam may have a greater likelihood of detection and improved communication rates compared to an individual base station beam225or UE beam220. For example, a dynamic beam that includes a set of base station beams225may be detected by the UE215at one or more antenna arrays positioned at various physical locations of the UE215, even if interference or path loss prevents detection of an individual base station beam225(e.g., a base station beam225-a).

The UE215may be configured to report a set of preferred base station beams225to the base station205for generation of the dynamic beam. The UE215may measure reference signals (e.g., a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a sounding reference signal (SRS), among other examples) transmitted via the base station beams225. For example, the UE215may measure a reference signal received power (RSRP), a reference signal received quality (RSRQ), a reference signal strength indicator (RSSI), a signal to noise ratio (SNR), a signal to interference plus noise ratio (SINR), or any combination thereof, associated with the reference signals. In some examples, each base station beam225may be identified by an indicator, such as a CSI-RS resource indicator (CRI) or a transmission configuration indication (TCI) state. Similarly, each corresponding UE beam220may be identified by an indicator, such as an SRS resource indicator (SRI).

According to the techniques described herein, the UE215may be configured to measure signal parameters and report a beam combination parameter identifying which base station beams225may be suitable for combining to generate the dynamic beam. For example, the UE215may measure a respective angular spread or coverage area for each base station beam225, array gains or received SNR gains at the UE215, other information related to panels or antenna modules at the UE215or the base station205, or any combination thereof. In some examples, the UE215may communicate with the base station205via a set of component carriers (CCs) or subbands in a CA configuration (e.g., inter-band CA or intra-band CA, within a single frequency range or across multiple frequency ranges). The UE215may report a separate beam combination parameter for each CC or subband in the CA configuration. The beam combination parameter (or parameters) may enable the base station205to determine whether to combine (e.g., co-phase) individual base station beams225to generate the dynamic beam.

The UE215may transmit a report230including the beam combination parameter to the base station205. The beam combination parameter may identify a signal quality (e.g., the measured signal parameters) corresponding to the set of beams suitable for combining to generate the dynamic beam. In some examples, the beam combination parameter may identify the preferred base station beams225. Additionally or alternatively, the UE215may identify the UE beams220corresponding to the preferred base station beams225. The UE215may identify the beams by including indicators (e.g., TCI states, CRIs, SRIs, among other examples) corresponding to the beams.

Based on the beam combination parameter, the base station205may generate the dynamic beam for communicating with the UE215. In some examples, the base station205may determine a channel related beam parameter for combining the individual base station beams225in phase. The channel related beam parameter may include a power delay profile for the dynamic beam, or timing and frequency offsets for the dynamic beam, or both. In some examples, the base station205may be constrained to generate the dynamic beam from the base station beams225identified in the report230.

The base station205may transmit a beam configuration235indicating the dynamic beam to the UE215. In some examples, the beam configuration235may indicate a respective signal synchronization block (SSB), a respective CSI-RS, or both, for each individual base station beam225of the dynamic beam. Based on the identified base station beams225in the beam configuration235, the UE215may compute the channel related beam parameter for the dynamic beam, and communicate with the base station205via the dynamic beam.

The base station305and the UE315may communicate with one another via one or more base station beams325and one or more UE beams330.

For example, a transmission from the base station305transmitted via a base station beam325-amay propagate along a cluster or path340-a, which may include a reflection345-a, and be received by the UE315via a UE beam320-a.

In some examples, a base station305may configure a dynamic beam (e.g., a composite beam) to improve communications reliability with the UE315. The dynamic beam may include one or more base station beams325or one or more UE beams320. The dynamic beam may have a greater likelihood of detection than an individual base station beam325or UE beam320. For example, a dynamic beam that includes a set of base station beams325may be detected by the UE315at one or more antenna subarrays330positioned at various physical locations of the UE315, even if interference or path loss prevents detection of an individual base station beam325(e.g., a base station beam325-a). The UE315may be configured to report a set of preferred base station beams325to the base station305for generation of the dynamic beam. The UE315may measure reference signals (e.g., a CSI-RS, a TRS, an SRS, among other examples) transmitted via the base station beams325.

The beam combination parameter may enable the base station305to determine whether to combine (e.g., co-phase) individual base station beams325to generate the dynamic beam.

The UE315may transmit a report including the beam combination parameter to the base station305. Based on the beam combination parameter, the base station305may generate the dynamic beam for communicating with the UE315. In some examples, the base station305may be constrained to generate the dynamic beam from the base station beams325identified in the report.

The base station305may transmit a beam configuration indicating the dynamic beam to the UE315. In some examples, the beam configuration335may indicate a respective SSB, a respective CSI-RS, or both, for each individual base station beam325of the dynamic beam. Based on the identified base station beams325in the beam configuration335, the UE315may communicate with the base station305via the dynamic beam.

For example, the process flow400may include example operations associated with one or more of a base station405or a UE415, which may be examples of the corresponding devices described with reference toFIGS.1and2. In the following description of the process flow400, the operations between the base station405and the UE415may be performed in a different order than the example order shown, or the operations performed by the base station405and the UE415may be performed in different orders or at different times.

The set of beams may include preferred beams suitable for combining to generate a dynamic beam (e.g., a composite beam). The dynamic beam may have a greater likelihood of detection or achievable rate than an individual beam of the set of beams. For example, a dynamic beam that includes one or more beams may be detected by the UE415at one or more antenna arrays positioned at various physical locations of the UE415, even if interference or path loss prevents detection of an individual beam. In some examples, the UE415may measure reference signals (e.g., a CSI-RS, a TRS, an SRS, among other examples) transmitted via the beams to determine the set of beams.
