Description

A kind of ascending control channel polymerization method of sending and receiving, terminal and base station
Technical field
The present invention relates to Long Term Evolution AS (LTE-Advanced, Long Term Evolutionadvanced system) field, particularly relate to a kind of ascending control channel polymerization method of sending and receiving, terminal and base station.
Background technology
In long evolving system (LTE, Long Term Evolution system), the up channel of terminal comprises Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (PUCCH) and Physical Random Access Channel (PRACH).Can transmitting data information, dispatch request (SR), hybrid automatic repeat-request (HARQ) and channel condition information (CSI) in PUSCH; SR, HARQ and CSI can be transmitted in PUCCH; PRACH is mainly used in the multi-upstream access of terminal, the running time-frequency resource being included in configuration sends lead code (Preamble) and carries out Stochastic accessing.The Preamble that base station receives terminal transmission needs to send Msg2 message for accidental access response to terminal, if terminal is based on non-competing Stochastic accessing, terminal receives Msg2 message and namely thinks that Stochastic accessing is successful; If terminal is based on competition Stochastic accessing, terminal also needs to send Msg3 message and solves for random access collision after receiving Msg2 message, base station needs to send Msg4 to terminal and solves instruction for random access collision after receiving the Msg3 of terminal transmission, when the terminal contention resolved mark received in the Msg4 of base station transmission identifies consistent with the contention resolved in Msg3, terminal thinks that contention resolved is successful.
In the prior art, under carrier aggregation (CA) scene, if multiple component carrier occurs that polymerization sends, because Stochastic accessing is only in main plot (Pcell) upper transmission, PUCCH also only sends on Pcell, at this moment there will not be the process multiple carrier wave sending simultaneously Random Access Channel and PUCCH.When the PUSCH of multiple carrier wave transmits simultaneously, if power limited, the power of multiple PUSCH and the maximum power value beyond terminal support, the then preferential power ensured with the PUSCH of ascending control information (UCI), then the PUSCH of other carrier waves adopts constant power to distribute.When PUCCH and PUSCH transmits simultaneously, if power limited, first the power of PUCCH and one or more PUSCH and the maximum power value beyond terminal support, then ensure the power of PUCCH, secondly ensure the power with the PUSCH of UCI, then other PUSCH adopt constant power to distribute.Because CA scene mainly considers desirable backhaul (backhual), the schedule information of multiple intercarrier is shared mutually, power allocation information is also shared mutually in time, at this moment multiple intercarrier mutually can cooperate and avoid exceeding the maximum power of terminal, when exceeding terminal maximum power, multiple carrier terminal equipment can be predicted and calculate the adjusted value of corresponding terminal for each carrier wave and channel.
HARQ binding mainly refers to, the HARQ information of multiple subframe is fed back in a subframe, the mainly binding of time domain, and in multiple subframe, the HARQ information of corresponding code word carries out bit AND-operation.
HARQ is multiplexing mainly to be referred to, the binding between two code words in a subframe, and the mainly binding in spatial domain, in a subframe, two code word HARQ information carry out bit AND-operation.
Consider to introduce double-strand connection technology in the R12 stage, double-strand connection technology and the maximum difference of CA are that two base stations (eNB) that double-strand connects have employed imperfect backhual and are connected, the scheduling independence between two nodes.Owing to introducing independent scheduling, two carrier waves can not share the power control information of uplink scheduling information and correspondence dynamically, if at this moment two carrier wave separate configurations maximum power values, can cause the limited waste of ascending power; If do not carry out independent limitation, the channel of two eNB configurations can cause terminal to send the channel power on two eNB and exceed the maximum power value of terminal support.At this moment need to introduce a kind of settlement mechanism, ensure that terminal is under double-strand connects scene, the scheme that many up channels that can process this power limited send.
