Description

RSSI configuration method, measurement method and related equipment based on unlicensed spectrum

Technical field

The present invention relates to the field of communications, and in particular, to an RSSI configuration method, a measurement method, and related equipment based on an unlicensed spectrum.

Background technique

With the rapid increase in communication traffic, 3GPP (3rd Generation Partnership Project, 3GPP) authorized spectrum is becoming insufficient to provide higher network capacity. To further improve the utilization of spectrum resources, 3GPP is discussing how to use unlicensed spectrum, such as the 2.4 GHz and 5 GHz bands, with the help of licensed spectrum. These unlicensed spectrums are currently mainly used in systems such as WiFi (Wireless Fidelity), Bluetooth, radar and medical. Generally, access technologies designed for licensed frequency bands, such as LTE (Long Term Evolution, LTE for short), are not suitable for use in unlicensed frequency bands because access technologies such as LTE optimize spectrum efficiency and user experience. The requirements are very high. However, carrier aggregation capabilities make it possible to deploy LTE to unlicensed bands. 3GPP proposes the concept of LAA (LTE Assisted Access, LTA), which uses the help of LTE licensed spectrum to use unlicensed spectrum. The unlicensed spectrum can work in two ways. One is the Supplemental Downlink, that is, only the downlink transmission subframe; the other is the time division duplex mode, and both the uplink and downlink transmission subframes are included. This situation can only be supplemented by the carrier aggregation technology.

Currently, the 3GPP stipulates that the UE needs to measure the RSSI (Received Signal Strength Indication, RSSI for short) of the cell on the unlicensed spectrum, and can support RSSI measurement with multiple time granularities. The minimum duration is 1 OFDM (Orthogonal Frequency). Division Multiplexing, Orthogonal Frequency Division Multiplexing (OFDM) symbol, the maximum is 5ms. According to the traditional RRM (Radio Resource Management, Radio Resource Management, RRM) measurement, if it is an inter-frequency measurement, it is necessary to measure the interval measurement gap. During the measurement gap, the receiver of the user is switched from the carrier frequency of the serving cell to the carrier frequency of the neighboring cell to be measured, that is, the receiving of the service base is stopped. The data and signaling of the station start to monitor the RRM measurement signal of the neighboring cell. For the RRM measurement of the same frequency, in the R12small cell on/off, since the DRS (Discovery Reference Signal, DRS) is introduced, When the small cell is in the off state, it will send DRS in the period of 40ms/80ms/160ms to ensure RRM measurement. Therefore, even for the same-frequency RRM measurement, it is necessary to perform measurement within 6 ms of the specific DRS transmission, that is, DMTC (DRS Measurement Timing Configuration, DMTC for short) configured in R12. It can be seen from the above that 3GPP specifies that the user needs to measure the RSSI of at least 1 symbol in the LAA, so whether it is for the same frequency RSSI measurement or the inter-frequency RSSI measurement, the location of the DMTC or measurement gap needs to be configured, how to DMTC or The configuration of the location of the measurement gap is currently a hot topic.
