In the fifth generation mobile communication technology (5G) New air interface (New Radio, NR) standard, a monitoring period, an offset (offset), and a duration (duration) of a Physical Downlink Control Channel (PDCCH) are all conditions that a base station notifies a terminal (e.g., User Equipment (UE)) through Radio Resource Control (RRC) signaling, and the monitoring period, offset, and duration of the PDCCH configured by some base stations are not reasonable.
For example, the PDCCH detection period configured by the base station is not reasonable, for example: the packet arrival period is 20 milliseconds (ms), but the PDCCH detection period configured by the base station is 2ms, and at this time, there are cases where a large number of terminals detect PDCCHs but do not detect scheduling grants (grants) (including a Downlink scheduling grant (DL grant) and an Uplink scheduling grant (UL grant) which respectively correspond to a PDCCH for scheduling a Physical Downlink Shared Channel (PDSCH) and a PDCCH for scheduling a Physical Uplink Shared Channel (PUSCH)).
In addition, a connection state (connected states) discontinuous reception (CDRX) parameter configured by the base station for the terminal may not match uplink traffic or downlink traffic of the terminal, and there may be a large number of cases where the terminal detects the PDCCH but does not detect the grant. On the other hand, in the current network device, the configuration manner (e.g. through RRC signaling) for configuring the synchronization signal or the measurement signal for the terminal is not flexible enough.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "comprises," "comprising," or any other variation thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. Furthermore, the use of "and/or" in the specification and claims means that at least one of the connected objects, such as a and/or B, means that three cases, a alone, B alone, and both a and B, exist.
In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.
For better understanding of the technical solution of the embodiment of the present invention, the following technical points are first introduced:
firstly, regarding a DCI format (DCI format):
currently, the following DCI formats are defined in NR:
Figure BDA0001829567310000041
two, different Search Space (SS) types:
a set of PDCCH candidates for terminal monitoring is defined according to a PDCCH search space. The search space type includes any one of: common search space Type 1(Type 1CSS), common search space Type 2(Type 2CSS), common search space Type 3(Type 3CSS), terminal-specific search space, and so on. The terminal may monitor the PDCCH candidates in the above one or more search spaces.
Third, regarding a Control Channel Element (CCE):
at present, there are 1, 2, 4, 8, and 16 CCE Aggregation Levels (AL) supported by NR.
Figure BDA0001829567310000051
The terminal-specific search space supports all five CCE Aggregation levels: 1. 2, 4, 8, 16 CCEs.
And fourthly, different PDCCH monitoring periods:
the NR system supports configuring a different PDCCH listening period (monitoring slot periodicity), offset (offset), and duration (duration) for each PDCCH search space.
Fifthly, regarding the DRX period of the RRC _ CONNECTED state:
the basic mechanism of the RRC _ CONNECTED state DRX is to configure one DRX cycle (cycle) for a terminal in the RRC _ CONNECTED state. The DRX cycle consists of "Duration (On Duration)" and "Opportunity for DRX" (DRX): in the duration time, the terminal monitors and receives the PDCCH (activation period); during the "opportunity for DRX" time, the terminal does not receive data of the downlink channel to save power consumption (sleep period).
As can be seen from fig. 1, in the time domain, time is divided into successive DRX cycles.
Where "drxStartOffset" specifies the starting subframe of the DRX Cycle and "long DRX-Cycle" specifies how many subframes a long (long) DRX Cycle takes, both parameters being determined by the "long DRX-Cycle startoffset" field. The on duration timer (onDurationTimer) specifies the number of consecutive subframes that need to monitor the PDCCH from the start subframe of the DRX cycle (i.e., the number of subframes for which the active period lasts).
In most cases, after a terminal is scheduled to receive or transmit data in a certain subframe, it is likely to continue to be scheduled in the next several subframes, and if it is required to wait for the next DRX cycle to receive or transmit the data, extra delay will be caused. In order to reduce such delay, the terminal may continue to be in the active period after being scheduled, that is, may continue to monitor the PDCCH during the configured active period. The realization mechanism is as follows: each time the terminal is scheduled to initially transmit data, a timer (drx-inactivity timer) is started (or restarted) and the terminal will remain in the active state until the timer times out. The drx-inactivity timer specifies the number of consecutive subframes that are continuously in an active state after the terminal successfully decodes a PDCCH indicating the initially transmitted Uplink (UL) or Downlink (DL) user data. I.e. the timer is restarted once each time the terminal has the initial data to be transmitted scheduled. It should be noted that here, the initial transmission is not the retransmission.
The techniques described herein are not limited to Long Time Evolution (LTE)/LTE Evolution (LTE-Advanced) systems, and may also be used for various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency Division Multiple Access (SC-FDMA), and other systems, for example: a fifth generation mobile communication (5th-generation, 5G) system and a subsequent evolution communication system.
The terms "system" and "network" are often used interchangeably. CDMA systems may implement Radio technologies such as CDMA2000, Universal Terrestrial Radio Access (UTRA), and so on. UTRA includes Wideband CDMA (Wideband Code Division Multiple Access, WCDMA) and other CDMA variants. TDMA systems may implement radio technologies such as Global System for Mobile communications (GSM). The OFDMA system may implement radio technologies such as Ultra Mobile Broadband (UMB), evolved-UTRA (E-UTRA), IEEE 802.11(Wi-Fi), IEEE 802.16(WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are parts of the Universal Mobile Telecommunications System (UMTS). LTE and higher LTE (e.g., LTE-A) are new UMTS releases that use E-UTRA. UTRA, E-UTRA, UMTS, LTE-A, and GSM are described in literature from an organization named "third Generation Partnership Project" (3 GPP). CDMA2000 and UMB are described in documents from an organization named "third generation partnership project 2" (3GPP 2). The techniques described herein may be used for both the above-mentioned systems and radio technologies, as well as for other systems and radio technologies.
It should be noted that, the time slot in this document may be a normal time slot, for example: the normal time Slot consists of 14 time domain symbols, or the time Slot may also be a minislot (Mini Slot) consisting of less than 14 time domain symbols, e.g. 2, 4 or 7 time domain symbols constituting one minislot. Of course, a slot herein may also be a Transmission Time Interval (TTI), a subframe (subframe), a time domain scheduling granularity, and the like.
