As shown in
It is to be understood that the wireless communication system 100 may be applicable to both a low-frequency scenario and a high-frequency scenario. The application scenarios of the wireless communication system 100 include but are not limited to a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a worldwide interoperability for microwave access (WiMAX) communication system, a cloud radio access network (CRAN) system, a future 5th-Generation (5G) system, a new radio (NR) communication system, or a future evolved public land mobile network (PLMN) system, etc.
The user equipment 102 shown above may be a user equipment (UE), a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent or user device, etc. The user equipment 102 may have a wireless transceiving function, capable of communicating (e.g., wireless communication) with one or more network devices 101 of one or more communication systems and accepting network services provided by the network device 101. The network device 101 here includes but is not limited to a base station as illustrated.
The user equipment 102 may be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with a wireless communication function, a computing device, or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, user equipment in a future 5G network, user equipment in a future evolved PLMN etc.
The network device 101 may be an access network device (or referred to as an access network site). Where, the access network device refers to a device that provides a network access function, such as a radio access network (RAN) base station. The network device may specifically include a base station (BS) device, or include a base station device and a wireless resource management device configured to control the base station device. The network device may further include a relay station (a relay device), an access point, as well as a base station in a future 5G network, a base station in a future evolved PLMN, or a NR base station. The network device may be a wearable device or vehicle-mounted device. The network device may also be a communication chip with a communication module.
For example, the network device 101 includes but is not limited to: a next-generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in an LTE system, a radio network controller (RNC), a node B (NB) in a WCDMA system, a wireless controller under a CRAN system, a base station controller (BSC), a base transceiver station (BTS) in a GSM system or CDMA system, a home base station (e.g., home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP) or a mobile switching center, etc.
In an example, a pilot used for radio link monitoring and link recovery, for example, a channel state information reference signal (CSI-RS), can only use a periodic RS, rather than a semi-persistent or aperiodic RS.
In some application scenarios (e.g., in a low traffic scenario), a base station only serves a few UEs in a connected state, which may be UE located at an edge of a cell or UE located at the center of the cell. Channel conditions corresponding to the UE at the edge of the cell and the UE at the center of the cell are different, so the manners of sending a pilot for the two UEs are to be distinguished according to their channel conditions.
For example:
In the case that the UE at the edge of the cell has a poor channel condition, the pilot may be sent at a higher power, a smaller period, or a higher frequency domain density.
In the case that the UE at the center of the cell has a good channel condition, the pilot may be sent at a lower power, a larger period, or a lower frequency domain density.
The energy consumption of a network device may be saved by using a flexible and dynamic manner of sending a pilot.
