TTI) is a basic transmission time unit for data transmission. Therefore, the transmission time interval of the uplink transmission and the downlink transmission is the subframe level, that is, 1 ms. In order to achieve shorter transmission time, the TTI is shortened into other time domain resources, and the time domain resources of the uplink transmission and the downlink transmission can be shortened, for example, from the current 14 symbols to 2 symbols.

In the LTE and LTE-A systems, the terminal device performs channel estimation according to the pilot signal, and reports the CSI obtained by the channel estimation to the base station, so that the base station selects an appropriate modulation and coding scheme based on the CSI reported by the terminal device (Modulation and Coding Scheme, referred to as MCS). The CSI includes a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Rank Indication (RI), and a Precoding Type Indicator (PTI). Information such as CSI-RS Resource Indicator (CRI) (Channel State Information-Reference Signals, CSI-RS for short). The CQI, PMI, RI, PTI, CRI, and periodic periods in the periodic CSI are respectively configured. For example, the reporting period of the CQI is 5 ms, the reporting period of the PMI is 5 ms, the reporting period of the transmitting RI is 10 ms, and the like. Aperiodic CSI is usually reported after 4ms or 5ms after the trigger.

The terminal device in the embodiment of the present invention may be a user equipment (UE). The user equipment may be a wireless terminal or a wired terminal, and the wireless terminal may be a device that provides voice and/or data connectivity to the user, a handheld device with wireless connectivity, or other processing device connected to the wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (eg, RAN, Radio Access Network), which can be a mobile terminal, such as a mobile phone and a computer with a mobile terminal, for example, can be portable, Pocket, handheld, computer built-in or in-vehicle mobile devices. For example, Personal Communication Service (PCS) telephone, cordless telephone, Session Initiation Protocol (SIP) telephone, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA) The device, the tablet computer, the notebook computer, and the like are not limited in the embodiment of the present invention.

The network device in the embodiment of the present invention may be a device in the access network that communicates with the terminal device through one or more sectors on the air interface, for example, a Base Transceiver Station (BTS) in GSM or CDMA. The present invention may also be a base station (NodeB) in WCDMA, or an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in LTE, or a device for allocating scheduling resources for terminal devices in 5G. The embodiment is not limited.

Kind of situation.

When the TTI is shortened to a time domain resource shorter than 1 ms, the simplest way is to directly change the reporting period of the CSI from the sub-frame level to the time domain resource level. For example, the CSI is sent once in 5 ms, and now it is 5 The time domain resource sends the CSI once. For example, the reporting period of the CQI is set to 5* time domain resources, the reporting period of the PMI is set to 5* time domain resources, and the reporting period of the RI is set to 10* time domain resources. The aperiodic CSI is set to report after 4* time domain resources or 5* time domain resources after the trigger. However, since the number of symbols included in the time domain resource is reduced, the amount of data that can be transmitted is also reduced, and the amount of information of the CSI is generally smaller. Larger, the CSI cannot be accurately transmitted, which may cause the base station to fail to accurately select the MCS, thereby reducing the downlink throughput. In particular, when the terminal performs multiple simultaneous transmissions of multiple carriers, the amount of CSI information to be transmitted is large, which may result in inaccurate transmission of CSI information, resulting in the base station not being able to accurately select the MCS. At the same time, the amount of CSI information sent is too large, which will also affect the uplink data transmission, which will cause the uplink throughput to decrease.

It should be noted that the time domain resource in the embodiment of the present invention may be replaced by a TTI, a short TTI (sort TTI), a symbol, a time slot, or other names that may indicate a length of a time domain resource.

Table 7A

Table 7B

Based on Table 7B, the terminal device determines the length of the first time length and/or the second time length by the IE of the first time length and/or the second time length.

It should be noted that the above four methods may be used alone or in combination, such as a combination of mode 1 and mode 4, a combination of mode 2 and mode 4, and a combination of mode 3 and mode 4. Certainly, in the embodiment of the present invention, the first time length and/or the second time length are determined by using the foregoing four manners, and other manners, such as the first time length and/or the second, may also be adopted. The length of time can be configured in a high-level signaling manner, or can be pre-defined in a protocol or standard, and the like.

It should be noted that the terminal device may determine the content included in the first information by using any one of the foregoing manners 1 to 3. The terminal device may also determine the first manner by using manners 1 to 3. The length of time, and/or the manner 4 is used to determine the second length of time.

Based on any of the foregoing embodiments, the terminal device in S13 sends the first information on a time domain resource having the first time length, and specifically includes the following two possible implementation manners:

In a mode, the terminal device sends the first sub-information on the first time domain resource, where the first time domain resource is one of the two times of the third indication information sending interval, and the first time is The time domain resource of the length, the reporting period of the first sub-information is less than or equal to the sending interval of the third indication information, and the first sub-information includes a part of the content in the first information.

Optionally, the method further includes: the terminal device receiving the third indication information.

Optionally, the third indication information includes content included in the first sub information.

In this manner, the transmission timing of the next third indication information is known to the terminal device. For example, the third indication information is periodically sent, and may be learned by using a high layer signaling configuration, a predefined in a protocol or a standard, or a first indication information or the third indication information or other indication information notification. The transmission timing of the next third indication information. As another example, the third The indication information is sent according to a setting rule, such as the time when the third indication information is sent for the first time is the i-th time domain resource on the downlink, and the time when the third indication information is sent for the second time is the downlink The i+1th time domain resource, the time when the third indication information is sent for the third time is the i+3 time domain resource on the downlink, and the time when the third indication information is sent for the fourth time is the downlink The i+5 time domain resource, etc., the time domain resource is an integer multiple of 1 symbol, and the length of the time domain resource may be the same as the first time length, or may be different. Optionally, the method may be configured by using a high layer signaling configuration, a predefined in a protocol or a standard, or the first indication information or the second indication information or the third indication information or other indication information notification manner. Set the rules.

In this manner, the accuracy of the first sub-information sent by the time when the transmission time of the next third indication information is the highest is the highest. Optionally, the first time domain resource is the next third indication information. The time domain resource with the first time length closest to the transmission time.

Of course, the first time domain resource in the embodiment of the present invention is not limited to the foregoing implementation manner, and other implementation manners may be used, for example, the first time domain resource is the sending of the third third indication information within the sending interval. The time domain resource having the first time length at the farthest time, or the first time domain resource having the first time length outside the first time distance from the transmission time of the next third indication information The time domain resource, etc., the first time distance may be k first time lengths, and k is greater than or equal to 1. The embodiment of the present invention does not limit the specific implementation of the first time domain resource.

For example, assume that the time when the third indication information is sent is the i th time domain resource on the downlink, and the time when the third indication information is sent next time is the jth time domain resource on the downlink, then the terminal The device transmits the first sub-information on the first time domain resource on the uplink closest to the jth time domain resource on the downlink. It can be understood that if an uplink subframe is 14 symbols, the first time length is 2 symbols, and one uplink subframe is divided into 7 time domain resources having the first time length. If the sending time of the third indication information is the control area of each downlink subframe, the first time domain resource is specifically the last time domain resource in the uplink subframe that has the first time length, or is in the uplink subframe. The third time domain resource with the first time length. When the sending time of the third indication information is an area of every n time domain resources, the first time domain resource is specifically the next time the third indication is sent. The time domain resource having the first time length in the latest uplink subframe of the time domain resource of the information, or n-4 first time lengths in the uplink subframe of the time domain resource that is to send the third indication information next time Time domain resources.

It should be noted that, if the sending time of the third indication information is irregular or aperiodic, the first time domain resource may be a pre-defined, or high-level configuration, or a location indicated by the DCI.

Optionally, the content that is included in the first sub-information may be configured by a high-level signaling, or may be predefined in a protocol or a standard, or may be determined by the terminal device, or may be The first indication information or the second indication information or the third indication information or other indication information is obtained, or a combination of the foregoing four manners. For example, the first sub-information is defined as CQI and RI in the protocol, and the PMI is indicated by the third indication information, and the terminal device determines that the first sub-information includes at least a PMI.

It should be noted that, if the reporting period of the first sub-information is greater than the transmission interval of the third indication information, the transmission may be performed according to the reporting period of the first sub-information.

The method is particularly applicable to a scenario in which the change of the first sub-information is slow, or the first sub-information does not change in a long period of time. A plurality of time domain resources having the first time length may be configured. If the first sub-information is sent on multiple time-domain resources having the first time length, resource waste is caused. The first sub-information may be sent at most once during the transmission interval of the third indication information, thereby saving resources.

In the mode B, the terminal device sends the second sub-information on the second time domain resource, where the second sub-information includes a part of the content or all the content in the first information except the first sub-information, where The second time domain resource is at least one time domain resource having the first time length except the first time domain resource in the sending interval of the third indication information, and the second sub-information The reporting period is less than or equal to the sending interval of the third indication information twice.

Specifically, the second sub-information may be sent in the sending interval according to a reporting period of the second sub-information.

Optionally, the content included in the second sub-information may be configured by high-level signaling, or may be Pre-defined in the protocol or the standard, which may be determined by the terminal device, or may be obtained by using the first indication information or the second indication information or the third indication information or other indication information. Or a combination of the above four ways. For example, the second sub-information in the protocol includes a CQI and a PMI, and the third indication information indicates only the PMI, and the terminal device determines that the second sub-information includes a CQI. It can be understood that at least the CQI is not included in the second sub information. It should be noted that, since the MCS includes an encoding and a code block scheme, the third indication information includes an MCS, which is equivalent to including a CQI.

The method is particularly applicable to the change of the second sub-information, and the reporting period of the second sub-information is required to be at least once in the sending interval according to the reporting period of the second sub-information. Sending the second sub-information to enable the network device to obtain the latest second sub-information.

It should be noted that the above modes A and B may be used alone or in combination.

According to any of the above embodiments, if the embodiment of the present invention is applied to the terminal device, the CSI corresponding to the different carriers needs to be reported, or the terminal device needs to report the corresponding CSI in different time lengths, in order to ensure the accuracy of the CSI transmission, according to the required report. The priority of the CSI, the CSI of the drop priority, as follows:

When the priority of the second information is lower than the priority of the first information, the terminal device discards the second information.

It can be understood that, when the priority of the second information is higher than the priority of the first information, the terminal device discards the first information and sends the second information.

The priority of the second information is lower than the priority of the first information, and includes the following possible implementation manners:

1. The priority of the second time length is lower than the priority of the first time length.

For example, the longer the length of time, the higher the priority of information sent on its corresponding time domain resource.

As another example, the shorter the length of time, the higher the priority of information sent on its corresponding time domain resource.

Optionally, the information indicating the priority of the different time lengths may be configured by the high-level signaling, or may be predefined in the protocol or the standard, or may be the first indication information or the second indication information. Or the third indication information or other indication information is obtained.

The priority of the process number of the Physical Hybrid-ARQ Indicator Channel (PHICH) is lower than the HARQ process where the first information is located. The priority of the number.

For example, the larger the HARQ process number, the higher the priority of the information sent on it.

As another example, the smaller the HARQ process number, the higher the priority of the information sent on it.

Optionally, the information indicating the priority of the different HARQ process IDs may be configured by the high layer signaling, or may be predefined in the protocol or the standard, or may be the first indication information or the second indication. Information or third indication information or other indication information obtained.

The priority of the CSI reporting type of the second information is lower than the priority of the CSI reporting type of the second information.

4. The priority of the type of the second information is lower than the priority of the type of the first information.

5. The priority of the cell identifier corresponding to the second information is lower than the priority of the cell identifier corresponding to the first information.

For example, the larger the cell identifier, the higher the priority of the CSI corresponding to the cell or the cell identifier.

For another example, the smaller the cell identifier, the higher the priority of the CSI corresponding to the cell or the cell identifier.

Optionally, the information indicating the priority of the identifier of the different cell may be configured by the high-layer signaling, or may be predefined in the protocol or the standard, or may be the first indication information or the second indication information. Or the third indication information or other indication information is obtained.

The priority of the second time domain resource set to which the time domain resource having the second time length belongs is lower than the priority of the first time domain resource set to which the time domain resource having the first time length belongs, where The first time domain resource set and the second time domain resource set comprise time domain resources of different lengths.

7. The CSI process identifier of the second information has a lower priority than the CSI of the first information. The priority of the process identifier.

Among them, the above seven methods may be used singly or in combination. When the at least two modes of the foregoing seven implementations are used in combination, the determining priority of the at least two modes is preset or configured, that is, the terminal device first determines that the priority is high according to the at least two modes. In a manner of determining, when the priority of the first information and the second information cannot be determined, determining according to the method of determining that the priority is the second highest in the at least two modes, and so on until determining The priority of the first information and the second information is high or low. In the embodiment of the present invention, the order of determining the priorities of the at least two modes is not limited.

For example, the priority of the priority of the CSI report, the priority of the time length, the priority of the CSI process identifier, the priority of the cell identifier, and the priority of the time domain resource set are as follows: . The terminal device first determines the priority of the CSI reporting type of the first information and the second information, as follows:

When the priority of the CSI reporting type of the second information is lower than the priority of the CSI reporting type of the first information, the terminal device discards the second information;

When the priority of the CSI reporting type of the second information is higher than the priority of the CSI reporting type of the first information, the terminal device discards the first information;

When the priority of the CSI reporting type of the second information is equal to the priority of the CSI reporting type of the first information, the terminal device determines the priority of the length of the first information and the second information again. Level, and so on, until the priority of the first information and the second information is determined.
