Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and a device for adaptively adjusting DRX configuration.
Background
In the field of mobile communication, spectrum resources are core resources for promoting industry development. With the rapid development of radio technology and the wide application of radio services, the contradiction between the scarcity of spectrum resources and the huge application requirements is increasingly prominent. An NR-U (New radio-Unlicensed), i.e., an Unlicensed band NR system, introduces an NR technique to an Unlicensed band to increase spectrum resources available to the system, thereby effectively improving system performance.
As a terminal power saving mechanism, DRX (Discontinuous Reception) is introduced in the LTE system, and its basic idea is: when the terminal has no data transmission/reception, the terminal is allowed to turn off the radio transmitting/receiving unit to enter a sleep mode to avoid unnecessary power consumption. When DRX is configured, the terminal may not need to continuously monitor a Physical Downlink Control Channel (PDCCH). Referring to fig. 1, DRX is configured by the following parameters:
on-duration timer: the terminal keeps an awakening state and monitors the PDCCH during the duration (on-duration), and after the terminal successfully decodes the PDCCH, an inactivity timer is started;
activity timer: before the inactivity timer is overtime, the terminal continuously monitors the PDCCH; when the inactivity timer is overtime, the terminal can enter the sleep state again; after the PDCCH which is transmitted for the first time (namely, non-retransmission) is decoded successfully, the terminal restarts the activity timer;
transmission-timer: during which the terminal waits for retransmissions;
cycle: on-duration and possibly a period of sleep thereafter.
However, in NR-U, since a WiFi network is deployed in an unlicensed band, NR using the unlicensed band will inevitably cause interference to Wi-Fi. To solve this problem, before data transmission, the base station needs to first perform LBT (listen-before-talk) operation to select available resources for data transmission, so as to achieve harmonious coexistence with WiFi. Notably, LBT operation is also used in licensed spectrum assisted access (LAA), which is introduced in 3GPP Release 13 as part of LTE Advanced Pro. It combines unlicensed spectrum (5GHz) and licensed spectrum together using carrier aggregation for the downlink. This frequency band aggregation results in faster data rates, more sensitive responsiveness, and better user experience.
If the DRX mechanism in the NR system is continuously used, the probability of LBT failure will cause less data transmission opportunities, which significantly affects the system performance. If carrier aggregation is introduced for improving UE rate, especially in SA scenarios of NR-U, with reference to DRX mechanism in LAA, then more energy consumption will result due to LBT operation of each carrier. Therefore, there is a need for enhancing DRX mechanism in NR system to achieve the purpose of NR-U system energy saving.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below by referring to the accompanying drawings and examples.
In the unlicensed band, the base station cannot acquire the channel due to LBT failure, and then the scheduling opportunity of the DRX UE will be blocked. To reduce scheduling delay due to LBT, the UE may be configured with a longer On-duration or short period. Furthermore, recklessly adjusting the DRX timer and period may result in unnecessarily high power consumption in view of the uncertainty of unlicensed spectrum channel access. In order to balance between the power consumption of the UE and the scheduling opportunity, the method and the device have the advantage that the DRX mechanism in the existing NR system is subjected to enhanced research and improvement based on channel occupation.
In order to solve the problems in the prior art, the invention provides a DRX configuration self-adaptive adjustment method based on channel occupation in an NR-U system, which has the following basic idea: in the DRX configuration self-adaptive scheme, channel occupation eta is considered, and a DRX period corresponding to the current channel occupation is determined to be used by the UE according to the mapping relation between the channel occupation and the DRX period. In addition, the influence of LBT failure probability on the DRX period is considered, and the DRX period is further adjusted, so that the adaptive adjustment of the DRX configuration of the NR-U system is realized in a more flexible mode.
Fig. 2 is a schematic diagram of a DRX configuration adaptive adjustment method based on channel occupancy in an NR-U system according to the present application, where the method includes the following steps:
step 201: and counting the channel occupation according to the set period T.
Step 202: when the DRX configuration is needed, determining a DRX period corresponding to the current channel occupation according to the current channel occupation and a preset mapping relation between the channel occupation and the DRX period.
The basic principle for setting the mapping relation between the channel occupation and the DRX period is as follows: when the channel occupancy is high (meaning that the probability of LBT success is low), a smaller DRX cycle is used to increase the transmission opportunity; conversely, when the channel occupancy is low, a larger DRX cycle is used. That is to say: the higher the channel occupancy, the smaller the DRX cycle.
Step 203: and counting the failure probability of the LBT in the period T, and if the failure probability of the LBT exceeds a preset threshold, reducing the determined DRX period to the nearest DRX period according to the mapping relation.
In this step, the influence of LBT failure probability on DRX cycle is mainly considered, and the DRX configuration is further adjusted on the basis of the configuration described in step 202, so that the adaptive adjustment of the DRX configuration of the NR-U system is realized in a more flexible manner. The "tuning down" in this step may tune down the DRX cycle determined in step 202 to the nearest DRX cycle according to the set mapping relationship between the channel occupancy and the DRX cycle.
On the basis of the scheme for periodically adjusting the DRX cycle shown in fig. 2, to further improve the flexibility of DRX configuration to meet the service requirement, the present application further provides a mechanism for event-triggered DRX cycle adjustment, which specifically includes:
after the base station fails LBT for M times continuously, the current DRX cycle is adjusted to be small through event triggering, that is: and according to the set mapping relation, the period value of the current DRX period is adjusted to be one DRX period closest to the current DRX period. Where M is greater than 1, its value may be determined according to a specific scenario.
The technical solution of the present application is further described in detail by a preferred embodiment.
The present embodiment first illustrates in detail how to set a mapping relationship between channel occupancy and DRX cycle, how to perform periodic DRX adjustment, how to perform event-triggered DRX adjustment, and the like, and then describes with reference to a specific implementation flow in conjunction with the accompanying drawings.

The channel occupancy η is derived based on RSSI measurements, i.e., counting the percentage of RSSI that is greater than a certain threshold over a period of time. The RSSI reflects the received power level of the ue on the configured carrier, and a larger RSSI value indicates a larger load on the measured carrier, and a smaller RSSI value indicates a smaller load on the measured carrier. When the base station is executed, a set of mapping tables of channel occupation and DRX period needs to be configured for the UE, the UE needs to report an RSSI measurement result so as to inform the base station, and the base station configures the mapping relation between the two.
In the embodiment, the channel occupancy is divided into L levels (from low to high), wherein the channel occupancy (arranged from small to large) corresponding to the level L (L is more than or equal to 1 and less than or equal to L) is

It should be noted that: m1DRX cycle＝long DRX cycle，MLDRX cycle is short DRX cycle. An example table of L ═ 5 is given below, as shown in table 1:
