Definitions
- the priority of the Chinese Patent Application for the "Improved Power Control Command Transmission Method and Apparatus” is hereby incorporated by reference in its entirety.
- the present invention relates to the field of communications technologies, and in particular, to an uplink power control command transmission method and apparatus. Background technique
- the Physical Uplink Control Channel (PUCCH) is supported on the Primary Component Carrier (PCC).
- PUCCH Physical Uplink Control Channel
- PCC Primary Component Carrier
- TPC Transmit Power Control
- DCI Downlink Control Information
- format format 1A/1B/1D/1/2A/2/2B/2C/2D
- cell-Radio cell radio network temporary identifier
- the Temporary Identifier is obtained by adding a TPC domain in a Physical Downlink Control Channel (PDCCH) or an Enhanced Physical Downlink Control Channel (Enhanced PDCCH).
- PDCH Physical Downlink Control Channel
- Enhanced PDCCH Enhanced Physical Downlink Control Channel
- the method is a TPC multicast mode, that is, an uplink TPC command of multiple UEs can be sent in the same PDCCH, and each user equipment (User Equipment, UE) obtains a TPC through a high-pre-configured power control-index (TPC-index).
- TPC-index power control-index
- the power adjustment is performed according to the uplink TPC command in the PDCCH acquired in the first manner.
- the Long Term Evolution (Advanced-Advanced, LTE-A) system introduces Carrier Aggregation (CA) technology, which aggregates multiple consecutive or discontinuous carriers under the same base station (e B ). Serve the UE. These aggregated carriers are called Component Carriers (CCs). Each cell can be a member carrier, and cells (member carriers) under different eNBs cannot be aggregated. In order to ensure backward compatibility with LTE UEs, the bandwidth of each carrier does not exceed 20 MHz at the maximum.
- a primary component carrier (PCC) is defined in the component carrier aggregated by the UE.
- the other component carriers are called Secondary Component Carriers (SCCs).
- a frequency division duplex (FDD) carrier and a time division duplex (TDD) carrier may be supported for carrier aggregation. Due to the different working modes of the FDD carrier and the TDD carrier, a new uplink acknowledgement/negative acknowledgement (ACK/NACK) transmission scheme may be introduced, namely:
- e B divides the aggregated downlink carriers into N downlink carrier groups Si, and one downlink carrier belongs to only one downlink carrier group, and the carriers in one downlink carrier group use the same duplex mode. All TDD carriers in a carrier group use the same TDD uplink/downlink configuration.
- the eNB configures an uplink carrier CUL,i for the downlink carrier group Si, and the uplink carrier CUL, i uses the same duplex mode as the downlink carrier group. If it is a TDD carrier, the uplink carrier uses the same TDD uplink/downlink configuration as the corresponding downlink carrier group.
- the uplink carriers corresponding to different downlink carrier groups are different.
- the ACK/NACK information corresponding to the downlink data received by the UE in the downlink carrier group Si is transmitted through the PUCCH on the uplink carrier CUL,i.
