In some embodiments, each RAN comprises a control apparatus 200. In alternative embodiments, two or more RANs may share a control apparatus.

[0117] Fig. 3 illustrates an example of a UE 300, such as the UE illustrated on Fig. 1 . The UE 300 is a communication device that is capable of (or configured for) sending and receiving radio signals. Non-limiting examples comprise a mobile station (MS) or mobile device such as a mobile phone or what is known as a ’smart phone’, a computer provided with a wireless interface card or other wireless interface facility (e.g., USB dongle), a personal data assistant (PDA) or a tablet provided with wireless communication capabilities, a machine-type communications (MTC) device, a Cellular Internet of things (CloT) device or any combinations of these or the like. The UE 300 may provide, for example, communication of data for carrying communications. The communications may be one or more of voice, electronic mail (email), text message, multimedia, data, machine data and so on.

[0118] The UE 300 may receive signals over an air or radio interface 307 via appropriate apparatus for receiving and may transmit signals via appropriate apparatus for transmitting radio signals. In Fig. 3 transceiver apparatus is designated schematically by block 306. The transceiver apparatus 306 may be provided for example by means of a radio part and associated antenna arrangement. The antenna arrangement may be arranged internally or externally to the mobile device.

[0120] The processor, storage and other relevant control apparatus can be provided on an appropriate circuit board and / or in chipsets. This feature is denoted by reference 304. The device may optionally have a user interface such as keypad 305, touch sensitive screen or pad, combinations thereof or the like. Optionally one or more of a display, a speaker and a microphone may be provided depending on the type of the device. A beam management procedure may refer to a procedure to align a transmission (TX) beam of a BS with a reception (RX) beam of a UE. The beam management procedure may comprise three phases: a first phase (P1 ), a second phase (P2) and a third phase (P3).

[0121] Fig. 4 shows a schematic representation of an example of P1 , P2 and P3 of a beam management procedure performed by a BS and a UE. The BS may perform beamforming. The UE may perform beamforming. The UE may operate in frequency range 2 (FR2). The UE may be equipped with multiple antenna panels. The UE may generate a broad RX beam via each antenna panel. The UE may generate multiple narrow RX beams via each antenna panel

[0122] In P1 the BS may perform a broad TX beam sweep from a set of broad TX beams. Each broad TX beam may be associated with a respective synchronization signal block (SSB). The SSBs may be sent sequentially in a SSB burst. The UE may perform a broad RX beam sweep from a set of broad RX beams.

[0123] The UE may measure each broad TX beam whilst using each broad RX beam. The UE may select a strongest broad TX beam based on the measurements. Here, the strongest broad TX beam is associated with SSBn. The UE may select a strongest broad RX beam based on the measurements. Here, the strongest broad RX beam is generated via the antenna panel directed toward the BS.

[0124] The UE may determine a strongest broad TX beam based on the measurements. The UE may transmit a measurement report including an indication of the strongest broad TX beam to the BS. Alternatively, the UE may transmit a measurement report including the measurements to the BS. The BS may determine the strongest broad TX beam to the BS based on the measurements.

[0125] In P2, the BS may perform a narrow TX beam sweep from a set of narrow TX beams. The narrow TX beams may be quasi-colocated with the broad TX beam selected by the UE in P1 . Each narrow TX beam may be associated with a respective channel state information reference signal (CSI RS).

[0126] The UE may measure each narrow TX beam whilst using the strongest broad RX beam. The measurements may include layer 1 (L1 ) reference signal received power (RSRP), reference signal received quality (RSRQ) or signal to interference plus noise (SINR) measurements. The UE may determine a strongest narrow TX beam based on the RSRP, RSRQ or SINR measurements. The UE may transmit a measurement report including an indication of the strongest narrow TX beam to the BS. Alternatively, the UE may transmit a measurement report including the RSRP, RSRQ or SINR measurements to the BS. The BS may select a strongest narrow TX beam based on the RSRP, RSRQ or SINR measurements. Here, the strongest narrow TX beam is associated with CSI RS3 (i.e. CSI3 on Figure 4).

[0127] In P3 the BS may repeat transmissions of the CSI RS on the strongest narrow TX beam. Here, the BS may repeat transmissions of CSI RS3. The UE may perform a narrow RX beam sweep from a set of narrow RX beams. The narrow RX beams may be generated via the antenna panel selected by the UE in P1. The UE may perform L1 RSRP or RSRQ measurements for the narrow RX beams. The UE may select a strongest narrow RX beam. The strongest narrow RX beam may be aligned with the strongest narrow TX beam.

[0128] It will be understood that the BS and the UE may perform the beam management procedure to select a narrow TX beam (serving TX beam) and a narrow RX beam (serving RX beam) to communicate.

[0129] The BS and the UE may subsequently perform the beam management procedure to select a narrow TX beam (candidate TX beam) and a narrow RX beam (candidate RX beam) to replace a previously selected narrow TX beam (serving TX beam) and a previously selected narrow RX beam (serving RX beam) to communicate.

[0130] In P1 or P2, the UE may measure the broad TX beam or the narrow TX beams periodically or semi-periodically (i.e., quasi-periodically).

[0131] The UE may transmit the measurement report periodically or semi-periodically. A high periodicity may allow to get a full and accurate picture of the UE conditions or channel conditions and to optimize beam switching. However, a high periodicity may increase the consumption of uplink resources to transmit the measurement report and may increase beam “ping-pong”.

[0132] Alternatively, the UE may transmit the measurement report aperiodically (e.g., when a measurement reporting event is detected). In this way, less uplink resource may be utilized for measurement reports transmission, more uplink resources may be utilized for data transmission, the data throughput may be improved and beam “ping-pong” may be reduced.

[0133] In this disclosure the expressions “measurement reporting event”, “measurement event”, “reporting event” or “event” may be used interchangeably. One or more aspects of this disclosure relate to configuring a UE that may transmit a measurement report when a measurement reporting event is detected, where the measurement event is selected amongst a plurality of measurement events based on at least one of a capability of the UE to determine a speed of the UE (i.e. , capable or not capable) or a speed of the UE (e.g., X kmph). In this way, less uplink resource may be utilized for measurement reports transmission, more uplink resources may be utilized for data transmission, the data throughput may be further improved and beam “ping-pong” may be further reduced.

[0134] A UE may receive, from a base station, a plurality of reference signal (RSs) transmitted on a plurality of TX beams. The UE may receive, from a base station, a plurality of reference signal (RSs) transmitted on a plurality of TX beams periodically or semi-periodically. The plurality of TX beam may comprise a serving TX beam and a plurality of candidate TX beams.

[0135] The serving TX beam may comprise a broad TX beam associated with a SSB and the plurality of candidate TX beams may comprise a plurality of broad TX beams associated with a plurality of SSBs.

[0136] The serving TX beam may comprise a narrow TX beam associated with a CSI RS and the plurality of candidate TX beams may comprise a plurality of narrow TX beams associated with a plurality of CSI RSs.

[0137] The UE may measure the RS transmitted on the serving TX beam and the RSs transmitted on the plurality of candidate TX beams. The UE may measure the RS transmitted on the serving TX beam and the RSs transmitted on the plurality of candidate TX beams periodically or semi-periodically. The UE may filter the measurement of the RS transmitted on the serving TX beam, for example using a temporal filter (e.g., averaging filter). The UE may filter the measurements of the RSs transmitted on the plurality of candidate TX beams, for example using a temporal filter (e.g., averaging filter). In this way, effects of fast fading may be minimized.

[0138] The measurement of the RS transmitted on the serving TX beam and the RSs transmitted on the plurality of candidate TX beams may comprise at least one of power measurements or quality measurements. Power measurements may comprise reference signal received power (RSRP) measurements. Quality measurement may comprise reference signal received quality (RSRQ) measurements or signal to interference plus noise ratio (SINR) measurements.

[0139] The UE may detect a measurement reporting event based on the measurements of the RS transmitted on the serving TX beam and the RSs transmitted on the plurality of candidate TX beams. The measurement reporting event may be selected amongst a plurality of measurement reporting events based on at least one of a capability of the UE to determine a speed of the UE or a speed of the UE.

[0140] The speed of the UE may comprise at least one of a translational speed or a rotational speed. The translational speed may refer to a distance per unit of time (e.g., expressed in meters per second or kilometre per hour (kmph)) or a number of TX beam switches per unit of time (e.g., expressed in number of TX beam switches per second). The translational speed may be determined based on measurements of the RS transmitted on the serving TX beam and the RSs transmitted on the plurality of candidate TX beams (e.g., a variation of measurements over a period of time may indicate a doppler effect). The translational speed may be determined using an accelerometer.

[0141] The rotational speed may refer an angle per unit of time (e.g., expressed in degrees per second) or a number of TX beam switches per unit of time (e.g., expressed in number of TX beam switches per second). The rotational speed may be determined using a gyroscope.

[0142] The speed of the UE may comprise at least one of an instantaneous speed or an average speed.

[0143] In an implementation, the UE may determine at least one of the capability of the UE to determine the speed of the UE or the speed of the UE. The UE may select the measurement reporting event amongst the plurality of measurement reporting events based on at least one of the capability of the UE to determine the speed of the UE or the speed of the UE. The speed of the UE may provide an indication that a beam switch is required.

[0144] Additionally or alternatively, the UE may determine at least one of the capability of the UE to determine whether an antenna panel is covered or whether an antenna panel is covered. The UE may select the measurement reporting event amongst the plurality of measurement reporting events based on at least one the capability of the UE to determine whether an antenna panel is covered (i.e., capable or not capable) or whether an antenna panel is covered (i.e. covered or not covered). Whether an antenna panel being covered may provide an indication that a beam switch is required.

[0145] In another implementation, the UE may transmit, to the base station, an indication of at least one of the capability of the UE to determine the speed of the UE or the speed of the UE. Alternatively, the BS may determine speed of the UE. The UE may receive, from the BS, the measurement reporting event selected, by the BS, amongst the plurality of measurement reporting events based on at least one of the capability of the UE to determine the speed of the UE or the speed of the UE.

[0146] In an implementation, the plurality of measurement reporting events may comprise at least one of a first measurement reporting event, a second measurement reporting event or a third measurement reporting event.

[0147] The first measurement reporting event (e.g., event 1 ) may comprise the power or quality measurement of a RS transmitted on one of the candidate TX beams (e.g., best candidate TX beam) being better than a power or quality measurement of the RS transmitted on the serving TX beam.

[0148] The second measurement reporting event (e.g., event 2) may comprise a power or quality measurement of the RS transmitted on one of the candidate TX beams (e.g., best candidate TX beam) being better than a power or quality measurement of the RS transmitted on the serving TX beam a power or quality measurement threshold (e.g. 3dB).

[0149] The UE may receive, from the BS, the power or quality measurement threshold, for example via RRC signalling. The power or quality measurement threshold may be selected, by the BS, amongst a plurality of power or quality measurement thresholds supported by the UE. The UE may transmit, to the BS, the plurality of power or quality measurement thresholds supported by the UE.

[0150] The third measurement reporting event (e.g., event 3) may comprise power or quality measurements of the RSs transmitted on K candidate TX beams (e.g., K best candidate TX beams) being better than a power or quality measurement of the RS transmitted on the serving TX beam, where K is equal to or greater than two (e.g., four).

[0151] In an implementation, the first reporting event may be selected when the UE is not capable of determining the speed of the UE. The second measurement reporting event may be selected when the UE is capable of determining the speed of the UE and the speed of the UE is greater than a speed threshold (e.g., 30kmph or 5 switches per second). The third measurement reporting event may be selected when the UE is capable of determining the speed of the UE and the speed of the UE is lower than the speed threshold.

[0152] The UE may receive, from the BS, the speed threshold, for example via RRC signalling. The speed threshold may be selected, by the BS, amongst a plurality of speed thresholds supported by the UE. The UE may transmit, to the BS, the plurality of speed thresholds supported by the UE.

[0153] In another implementation, the first measurement reporting event may be selected when the UE is capable of determining the speed of the UE and the speed of the UE is lower than a first speed threshold (e.g., 1 kmph). The third measurement reporting event may be selected when the UE is capable of determining the speed of the UE and the speed of the UE is greater than the first speed threshold and lower than a second speed threshold (e.g., 30kmph). The second measurement reporting event may be selected when the UE is capable of determining the speed of the UE and the speed of the UE is greater than the second speed threshold. The UE may receive, from the BS, the first speed threshold and the second speed threshold for example via RRC signalling.

[0154] The UE may receive, from the BS, the first speed threshold and the second speed threshold, for example via RRC signalling. The first speed threshold and the second speed threshold may be selected, by the BS, amongst a plurality of first speed thresholds and second speed thresholds supported by the UE. The UE may transmit, to the BS, the plurality of first speed threshold and the second speed threshold supported by the UE.

[0155] The UE may transmit, to the BS, a measurement report. The UE may transmit, to the BS, a measurement report aperiodically (i.e., when the measurement reporting event is detected).

[0156] The measurement report may comprise an indication of at least one RS transmitted on at least one TX beam. For example, the measurement report may indicate the RS transmitted on the serving TX beam. The measurement report may indicate the RS transmitted on a candidate TX beam (e.g., best candidate TX beam). The measurement report may indicate the RS transmitted on K candidate TX beams (e.g., K best candidate TX beams).

[0157] The measurement report may comprise an indication of at least one measurement associated with at least one RS transmitted on at least one TX beam. For example, the measurement report may indicate a measurement associated with the RS transmitted on the serving TX beam. The measurement report may indicate a measurement associated with the RS transmitted on a candidate TX beam (e.g., best candidate TX beam). The measurement report may indicate a measurement associated with the RS transmitted on K candidate TX beams (e.g., K best candidate TX beams).

[0158] The measurement report may comprise an indication of at least one TX beam. For example, the measurement report may comprise an indication of the serving TX beam. The measurement report may comprise an indication of a candidate TX beam (e.g., best candidate TX beam) or an indication of K candidate TX beams (e.g., K best candidate TX beam).

[0159] The BS may select a TX beam based on the measurement report. For example, the BS may select a candidate TX beam (e.g., best candidate TX beam or one of the K best candidate TX beams).

[0160] The UE may receive, from the BS, an indication of the selected TX beam e.g., best candidate TX beam or one of the K best candidate TX beams).

[0161] The advantage of the above mechanism may be two folded. Firstly, measurement report is transmitted to the BS aperiodically when there is a need as opposed to periodically or semi- periodically. Hence, measurement report transmission overhead may be reduced. Secondly, periodical or semi-periodical measurement report transmissions may trigger beam “ping-pong” because of fast fading. Aperiodical measurement report transmissions may reduce the beam “ping-pong” and eventually the user throughput.

[0163] The UE may receive a plurality of RSs transmitted on a plurality of TX beams.

[0164] The UE may measure the RSs transmitted on the plurality of TX beams.

[0165] If the UE is not capable of determining a speed of the UE, the UE may select a first measurement reporting event.

[0166] If the UE is capable of determining a speed of the UE and the speed of the UE is greater than a speed threshold p, the UE may select a second measurement reporting event. If the UE is capable of determining a speed of the UE and the speed of the UE is lower than the speed threshold p, the UE may select a third measurement reporting event.

[0167] The UE may detect the selected measurement reporting event based on the measurement of the RSs transmitted on the plurality of TX beams.

[0172] The UE may receive a plurality of RSs transmitted on a plurality of TX beams.

[0173] The UE may measure the RSs transmitted on the plurality of TX beams.

[0174] If the UE is capable of determining a speed of the UE and the speed is lower than a first speed threshold p1 , the UE may select a first measurement reporting event.

[0175] If the UE is capable of determining a speed of the UE and the speed of the UE is greater than the first speed threshold p1 and lower than a second speed threshold p2, the UE may select a third measurement reporting event.

[0176] If the UE is capable of determining a speed of the UE and the speed of the UE is greater than the second speed threshold p2, the UE may select a second measurement reporting event.

[0177] The UE may detect the selected measurement reporting event based on the measurement of the RSs transmitted on the plurality of TX beams.

[0178] The UE may transmit to the BS, a measurement report.

[0179] The BS may select a TX beam based on the measurement report. The UE may receive, from the BS, an indication of the selected TX beam.

[0180] Fig. 6 shows bar charts of ratio between a number of aperiodical measurement report transmissions triggered by a measurement reporting event and a number of periodical or semi periodical measurements, when the measurement reporting event is a first measurement reporting event, a second measurement reporting event and a third measurement reporting event and when a translational speed is 3kmph and 120kmph.

[0181] The ratio between a number of measurement report transmissions triggered by the first measurement reporting event and a number of periodical or semi periodical measurements may be reduced by 65% compared to a ratio between a number of periodical or semi periodical measurement report transmissions and a number of periodical or semi periodical measurements (assuming that the measurements and the measurement report transmissions have the same periodicity).

[0183] The ratio between a number of measurement report transmissions triggered by the second measurement reporting event and a number of periodical or semi periodical measurements may be reduced by 75% compared to a ratio between a number of periodical or semi periodical measurement report transmissions and a number of periodical or semi periodical measurements (assuming that the measurements and the measurement report transmissions have the same periodicity).

When the speed of the UE increases from 3kmph to 120kmph, the ratio between a number of measurement report transmissions triggered by the third measurement reporting event and a number of periodical or semi periodical measurements may be increased by 3 to 5%.

[0186] Fig. 7 shows bar charts of data throughputs for aperiodical measurement report transmissions triggered by a measurement reporting event, when the measurement reporting event is a first measurement reporting event, a second measurement reporting event and a third measurement reporting event and when a user equipment has poor channel conditions (i.e., cell-edge UE or 5thpercentile) and median channel conditions (i.e., cell-median UE or 50thpercentile).

[0187] The third measurement reporting event may provide the highest data throughput, when the speed of the UE is 3kmph (i.e., low speed) and when the UE has poor channel conditions (i.e., cell-edge UE or 5thpercentile) or median channel conditions (i.e., cell-median UE or 50thpercentile).

[0188] The second measurement reporting event may provide the highest data throughput, when the speed of the UE is 120kmph (i.e., high speed) and when the UE has poor channel conditions (i.e., cell-edge UE or 5thpercentile) or median channel conditions (i.e., cell-median UE or 50thpercentile).

[0189] The same trends may be observed when the UE has good channel conditions (i.e., cell-centre UE or 95thpercentile).
