Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for configuring and processing a reference signal, a network side device, and a terminal.
Background
Unlike the 4G LTE (Long Term Evolution) that uses CRS (Cell Reference Signal), the 5G NR (New Radio, New air interface) introduces TRS (Tracking Reference Signal) for estimation of large-scale channel characteristics such as fine time/frequency synchronization, delay spread, and doppler spread. Currently, the TRS can only be configured through a Radio Resource Control (RRC) signaling dedicated to the terminal, that is, can only be configured for the RRC connected terminal. The TRS is also a CSI-RS (Channel State Information Reference Signal), and if an RRC parameter of the TRS-info is configured in a certain CSI-RS resource set in RRC signaling, the CSI-RS is used for time/frequency tracking, that is, the TRS.
In order to meet the tracking range of the frequency error and the resolution of the timing error, the TRS needs to meet certain configuration requirements, which specifically include parameters such as a TRS period, a TRS frequency domain density, a TRS occupied bandwidth, a number of symbols in a time slot of the TRS, a symbol interval, and the like.
The current TRS can only be configured for an RRC connected terminal, terminals in an RRC idle state and an inactive state cannot use the TRS, and synchronization tracking and the like can only be performed by using an SS/PBCH block (synchronization signal/physical broadcast channel block), where the SS/PBCH block is sent according to a cycle and a default cycle is 20 ms. Before receiving paging signals each time, the terminals in the RRC idle state and the inactive state need to wake up a long time in advance and receive the SS/PBCH block for synchronous tracking. In LTE, each timeslot has a CRS, so the terminal can detect the CRS by only 1 or several timeslots in advance, and receive the paging signal after acquiring synchronization. In the 5G NR, since the terminals in the RRC idle state and the inactive state can only synchronize through the SS/PBCH block, the terminals need to wake up in advance for a long time (for example, one or several SS/PBCH block periods), which results in that the time for detecting the paging signal is longer and the energy consumption is increased compared to the 4G LTE.
A method for reducing the energy consumption overhead of paging signal detection of idle and inactive terminals is to configure an additional TRS for the terminal, but at present, the TRS can only be configured through dedicated RRC signaling of the terminal and cannot be configured for the idle and inactive terminals.
In summary, when the terminal in the idle state or the inactive state is synchronized by the SS/PBCH block, the time of the procedure for detecting the paging signal is prolonged, and the energy consumption is increased.
