Description

A method and device for processing channel state information

technical field

The present invention relates to wireless network technology, in particular to a method and device for processing channel state information.

Background technique

The throughput requirements of wireless networks are becoming higher and higher, and high-rate data services are growing as the main application of wireless networks. For example, 3GPP (3rd Generation Partnership Project) LTE-A (Long Term Evolution Advanced) specifies high data rate requirements for uplink and downlink loads.

The multiplexing capacity of the enhanced channel enables high data rate requirements to be realized, and the uplink control information (Uplink Control Information, UCI) can be multiplexed in the shared physical channel, that is, PUSCH (Physical UplinkShared Channel, uplink physical shared channel). Multiplexing. In order to report the downlink channel status from UE (User Equipment, user equipment) to eNodeB (Evolved NodeB, evolved NodeB), CSI (ChannelState Information, channel state information) is defined in LTE-A. There is a type of CSI called periodic CSI (Period CSI, P-CSI), which is reported periodically, that is, if there is data on the PUSCH, the UE multiplexes and sends P-CSI on the PUSCH.

In the 3GPP LTE protocol, UE will unconditionally send P-CSI on PUSCH. If PUSCH resource elements (Resource Elements, REs) are occupied by P-CSI bits, fewer resource elements can be used by data. It improves the PUSCH data coding rate and reduces the PUSCH data decoding performance. If the PUSCH data encoding rate is too high, resulting in data decoding failure, the entire PUSCH data transmission block (Transport Block, TB) will be retransmitted. However such a retransmission is not necessary since decoding failures are predictable before the eNodeB decodes according to the high coding rate.

LTE-A provides indirect rate matching for PUSCH data. Since no coding rate detection is performed based on uplink control information multiplexed on PUSCH, retransmission is performed explicitly. Retransmission can reduce the encoding rate by sending PUSCH data based on different redundant information.

But retransmission has the following disadvantages: 1) Frequency utilization will be reduced. Retransmissions are not worth it, since almost all data has already been sent via the original transmission. If it is in a marginal position, a decline of close to 50% can be expected. 2) The reliability of P-CSI will also be affected. The number of resource units of P-CSI is related to the data to be sent. If more data is sent, less resource units can be used for P-CSI, which may cause P-CSI decoding failure.

b) When the first device includes a base station, the base station acquires a preset coding rate. When the first base station includes a mobile terminal, the mobile terminal receives a preset coding rate from the base station.

Those skilled in the art can understand that the above method of obtaining the encoding rate of the current channel and the preset encoding rate is only an example. included within the scope of the present invention and incorporated herein by reference.

Specifically, the coding rate of the channel on which the first device is currently performing data transmission may be compared with a preset coding rate according to the instruction of detecting the coding rate.

Taking the first device including a mobile terminal as an example below, how to compare the coding rate of the channel on which the first device is currently transmitting data with the preset coding rate according to the instruction of detecting the coding rate.

Example 1

In this example, the base station includes the instruction for detecting the coding rate in an RRC (Radio Resource Control, radio resource control) connection establishment message and sends it to the mobile terminal, or sends the instruction for detecting the coding rate separately after establishing a connection with the mobile terminal to the mobile terminal. After receiving the instruction to detect the encoding rate, the mobile terminal determines whether to detect the encoding rate according to the instruction. Optionally, taking the example that the base station sends the instruction for detecting the encoding rate to the mobile terminal in the RRC connection establishment message, a variable for detecting the encoding rate can be preset, and a bit is occupied in the RRC connection establishment message to indicate whether the mobile terminal needs to Detecting the encoding rate, for example, if the value of the detecting encoding rate variable is 1, it indicates that the mobile terminal needs to detect the encoding rate, if the value of the detecting encoding rate variable is 0, it indicates that the mobile terminal does not need to detect the encoding rate; or the detecting encoding rate If the value of the variable is 0, it indicates that the mobile terminal needs to detect the coding rate, and if the value of the detected coding rate variable is 1, it indicates that the mobile terminal does not need to detect the coding rate.

When the value of the detected coding rate variable indicates that the mobile terminal needs to detect the coding rate, the mobile terminal obtains the coding rate and the preset coding rate of the channel where the mobile terminal is currently transmitting data.

Wherein, the mobile terminal calculates and obtains the coding rate of the channel on which the mobile terminal currently performs data transmission according to formula (1).

Wherein, the base station sends the preset coding rate index value to the mobile terminal. Optionally, the base station can include the preset coding rate index value in the RRC connection establishment message and send it to the mobile terminal, or send the preset coding rate index value to the mobile terminal. The value is sent separately to the mobile terminal. After the mobile terminal obtains the encoding rate index value, according to the encoding rate index value, it searches in the preset encoding rate index value and encoding rate mapping table to obtain the encoding rate corresponding to the preset encoding rate index value. For example, in Table 1, the mobile terminal receives the preset encoding rate index value of 5 from the base station, then query in the mapping table of the preset encoding rate index value and encoding rate to obtain the corresponding preset encoding rate is 0.93.

Subsequently, the calculated coding rate of the channel on which the mobile terminal is currently performing data transmission is compared with the preset coding rate.

When the value of the detected coding rate variable indicates that the mobile terminal does not need to detect the coding rate, the mobile terminal carries the CSI of the current channel of the mobile terminal in the PUSCH data and sends it to the base station.

When the encoding rate of the current channel is greater than the preset encoding rate, detect whether the channel state information delay of the current channel reaches the preset delay threshold; when the channel state information delay of the current channel does not reach the preset delay threshold, save the channel of the current channel state information, or, when the delay of the channel state information of the current channel reaches a preset delay threshold, discarding the channel state information of the current channel, preferably, when the first device includes a base station, when the delay of the channel state information of the current channel reaches The preset delay threshold, the base station notifies the scheduler corresponding to the base station to reduce the coding rate.

Optionally, when the delay of the channel state information of the current channel does not reach the preset delay threshold, the detection coding rate variable is set as an instruction to detect the coding rate, for example, the value of the detection coding rate variable is set to 0, and the channel of the current channel The delay of the state information reaches the preset delay threshold, and the detection coding rate variable is set to an instruction that does not need to detect the coding rate, for example, the value of the detection coding rate variable is set to 1.

Wherein, the preset delay threshold includes but not limited to a CSI reporting period.

Those skilled in the art can understand that the above preset delay threshold is only an example, and other preset delay thresholds, if applicable to the present invention, should also be included in the protection scope of the present invention and included here by reference.
