Definitions
- the present application relates to, but is not limited to, the field of mobile communication technologies, and in particular, to a method and device for processing uplink signal transmission power, a base station, and a terminal.
- the Physical Downlink Control Channel (PDCCH) is used to carry uplink and downlink scheduling information and uplink power control information.
- Downlink Control Information (DCI) format is divided into DCI format 0, 1, 1A, 1B, 1C, 1D, 2, 2A, 3, 3A, etc., and later evolved to LTE-A Release 12 (LTE).
- DCI format 2B, 2C, 2D has been added to -A Release 12) to support a variety of different applications and transmission modes.
- the base station eNB, e-Node-B
- the uplink power control in the wireless system is very important. Through the uplink power control, the UE in the cell can ensure the quality of the data sent by the uplink, minimize the interference to other users in the system, and prolong the use time of the UE battery. .
- LTE/LTE-A LTE-Advanced
- uplink data between different users in the same cell is orthogonal. Therefore, the LTE system uses slow uplink power control, mainly considering power control.
- the uplink transmission is adapted to different wireless transmission environments, including path loss (PL), shadow fading, and the like.
- the LTE power control includes a PUCCH (Physical Uplink Control Channel), a PUSCH (Physical Uplink Shared Channel), and a SRS (Sounding Reference Signal).
- PUCCH Physical Uplink Control Channel
- PUSCH Physical Uplink Shared Channel
- SRS Sounding Reference Signal
- the open loop industrial control point target power P0 + open loop path loss compensation ⁇ ⁇ (PL).
- the target power P0 is further divided into two parts: the cell target power and the UE-specific target power.
- the open loop path loss PL is based on the UE's estimate of the path loss for the downlink.
- the UE performs path loss estimation by measuring a downlink reference signal RSRP (Reference Signal Receiving Power) and subtracting it from a known RS (Reference Signal) signal power.
- RSRP Reference Signal Receiving Power
- the eNodeB determines the weight of the path loss in the uplink power control of the UE by the parameter ⁇ . For example, for a UE at the edge of a cell, if its transmit power is too high, it will cause interference to other cells, thereby reducing the capacity of the entire system. For PUCCH, since different PUCCH users are code division multiplexed, and ⁇ is 1, the interference between different PUCCH users can be better controlled.
- the dynamic power offset consists of two parts, power adjustment ⁇ TF based on MCS (Modulation and Coding Scheme) and closed loop power control.
- the MCS based power adjustment may cause the UE to dynamically adjust the corresponding transmit power spectral density based on the selected MCS.
- the power control of the closed loop refers to that the UE adjusts the transmit power of the UE by using a TPC (Transmitted Power Control) command in the PDCCH.
- TPC Transmitted Power Control
- the cumulative adjustment method is applicable to PUSCH, PUCCH, and SRS, and the absolute value adjustment method is only applicable to PUSCH.
- the transition between the two different adjustment modes is semi-static.
- the eNB indicates whether the UE adopts the cumulative adjustment mode or the absolute value adjustment mode through dedicated RRC (Radio Resource Control) signaling.
- RRC Radio Resource Control
- the cumulative adjustment mode means that the current power adjustment value is increased or decreased by the value of the last power adjustment, and the adjustment adjustment step is the default adjustment method used by the UE.
- the TPC of the cumulative adjustment mode in LTE can have two sets of different adjustment steps, the first set of steps is (-1, 0, 1, 3) dB, for PUSCH, indicated by DCI format 0/3; for PUCCH, by PUCCH DCI format 1/1A/1B/1D/2/2A/3 indication.
- the second set of steps is (-1, 1), indicated by DCI format 3a (for PUCCH and PUSCH).
- the absolute value adjustment method refers to directly using the power adjustment value indicated in the TPC, and is applicable only to the PUSCH. At this time, the eNodeB needs to explicitly turn off the power adjustment mode of the cumulative adjustment mode through RRC signaling.
- the TPC value is (-4, -1, 1, 4) dB
- the DCI format 0/3 indicates that the power adjustment range is up to 8 db, which is applicable to the discontinuous uplink transmission of the UE, and can enable the eNodeB to adjust the UE's transmit power to the expected value in one step.
- High-frequency carrier communication has a large available bandwidth and can provide efficient high-speed data communication.
- a big technical challenge faced by high-frequency carrier communication is that relatively low-frequency signals, the fading of high-frequency signals in space is very large, although the high-frequency signals in the outdoor communication have a spatial fading loss problem, but because of With its wavelength reduction, more antennas can usually be used so that communication can be based on the beam to compensate for fading losses in space.
