Definitions
- the embodiments of the present invention relate to the field of communications, and in particular, to a method for transmitting uplink information, a base station, and a user equipment.
- the user equipment In the machine type communication (English name: Machine Type Communication, English abbreviation: MTC), the user equipment (English name: User Equipment, English abbreviation: UE) has a large number of users, and it is necessary to reduce the complexity or cost of the UE. Reducing the bandwidth of the received and transmitted signals supported by the UE is one of the main techniques used to reduce the complexity or cost of the UE. For example, the bandwidth of the UE receiving and transmitting signals is only 1.4 MHz.
- LTE Long Term Evolution
- LTE Advanced Long-term evolution
- LTE-A advanced long-term evolution
- Resources within the bandwidth of the LTE system are divided into subcarriers in frequency.
- the resources of the LTE system are divided into radio frames (ie, system frames) in time, and one radio frame is 10 ms.
- a radio frame contains two 5ms half frames.
- a radio frame contains 10 subframes, one subframe is 1 ms long, and one subframe contains two slots.
- the uplink of the LTE system uses single-carrier frequency-division multiple access (English name: Single-carrier Frequency-Division Multiple Access, English abbreviation: SC-FDMA). Each time slot contains 6 or 7 SC-FDMA symbols.
- a physical resource block (English full name: Physical Resource Block, English abbreviation: PRB) contains 12 subcarriers in frequency. A PRB occupies one time slot in time.
- the LTE system supports two frame structures: Type1 and Type2, where Type1 is used for frequency division duplex (English name: Frequency Division Duplexing, English abbreviation: FDD), and Type2 is used for time division duplex (English full name: Time Division Duplexing, English abbreviation) :TDD).
- Type 1 Frequency Division Duplexing, English abbreviation: FDD
- Type2 time division duplex
- TDD Time Division Duplexing
- each subframe included in a 10 ms radio frame can transmit both downlink information and uplink information.
- a subframe included in a 10 ms radio frame is either a downlink subframe, an uplink subframe, or a special subframe. Which specific subframe is the downlink
- the subframe, the uplink subframe, and the special subframe are determined by the uplink and downlink configurations.
- LTE TDD supports 7 different uplink and downlink configuration options.
- the frequency resources within the LTE system bandwidth can be divided into narrowbands.
- the frequency bandwidth of the narrowband included frequency resource does not exceed the working bandwidth supported by the UE.
- a narrowband has a frequency width of only 1.4 MHz, or a frequency width of six PRBs.
- the transmission of the uplink information of the MTC can be switched between different narrowbands.
- Switching between low-complexity or low-cost UE transmission information between different narrowbands requires a maximum of 2 symbols for frequency adjustment.
- the UE frequency adjustment for low complexity or low cost is used. That is, the first narrowband of the first subframe and the second narrowband of the second subframe transmit uplink information of the UE, and at least one interval subframe between the first subframe and the second subframe. In the interval subframe, the UE performs frequency adjustment between the first narrowband and the second narrowband without transmitting uplink information.
- the above-mentioned prior art interval subframe has at least 1 ms, which is far greater than the frequency adjustment time of a maximum of 2 symbols required for a UE with low complexity or low cost to transmit uplink information between different narrowbands. This will cause unnecessary transmission delay for the transmission of uplink information.
- leaving the interval subframe will result in the division of resource utilization in the time dimension, which increases the complexity of base station resource scheduling.
