Description

Information scheduling method, receiving method and related device

Technical Field

The present application relates to the field of communications, and in particular, to an information scheduling method, an information receiving method, and a related apparatus.

Background

Currently, a carrier aggregation technology between base stations is introduced in Long Term Evolution (Long Term Evolution, LTE for short) and Long Term Evolution-Advanced (Long Term Evolution-Advanced, LTE-a for short) systems, and the carrier aggregation technology between base stations is also called as a dual connectivity technology. In the dual connectivity technology, when data is transmitted between two base stations performing carrier aggregation, the data may be ideally or non-ideally backhauled, so that the starting time of a downlink subframe sent by the two base stations to a User Equipment (UE) may be synchronous (for example, in a dual connectivity scenario of carrier aggregation) or asynchronous (for example, in an asynchronous dual connectivity scenario). In an asynchronous scene, starting times of downlink subframes of the two base stations can have any time difference, and each base station can receive uplink subframes corresponding to a plurality of different Timing Advance groups (TAG for short), so that the starting times of the uplink subframes sent to the two base stations by the UE can also have any time difference, that is, overlapping time can exist between the uplink subframes, and the overlapping time is a non-fixed value. The TAG is a cell group in which the timing of uplink transmission channels of UEs of cells is the same. In the prior art, the cross-carrier scheduling technology is only supported during ideal backhaul, and for the non-ideal backhaul situation, the cross-carrier scheduling is not supported considering that the interaction delay between two base stations is large.

In a 5G scenario, because the minimum transmission time granularity (i.e., the minimum time unit for transmitting data, such as a subframe in LTE) and the air interface transmission delay at different carrier frequencies are different, for example, the air interface transmission delay at low frequency 2GHz is 4-5 ms, and the air interface transmission delay at higher frequency, such as 28GHz or 70GHz, is 1 ms. In addition, there are different minimum time granularities and timing settings at different carrier frequencies. Specifically, one subframe length of the high frequency 28GHz is 0.3ms, and one subframe length of the low frequency 2GHz may be set to 1 ms. Thus, one low-frequency subframe corresponds to a plurality of high-frequency subframes, for example, in fig. 1, a plurality of high-frequency subframes corresponding to the low-frequency subframe 0 are sequentially the high-frequency subframe 0, the high-frequency subframe 1, and the high-frequency subframe 2.

In a 5G scenario, a first subframe of a first carrier may overlap with M (M is greater than or equal to 1) second subframes of a second carrier in a time domain. Considering that if the carrier frequency corresponding to the first carrier is low, the reliability of the channel transmission is high; if the carrier frequency corresponding to the second carrier is higher, the time delay of the channel transmission is lower. Under the condition that the first subframe is overlapped with M (M is more than or equal to 1) second subframes, the control information on the second carrier is placed on the first carrier for transmission, and the transmission time delay is larger than that when the control information is transmitted by the second carrier while the reliability is higher. Therefore, the configuration of cross-carrier scheduling in the 5G scenario becomes more complex, and how to implement flexible cross-carrier scheduling of control information on the first carrier and the second carrier, thereby implementing a compromise between reliability and transmission delay is a problem to be solved in the 5G scenario.

Disclosure of Invention

The application provides an information scheduling method, an information receiving method and a related device, which can flexibly configure different cross-carrier scheduling instructions for control information on a carrier, thereby realizing compromise between reliability and transmission delay of transmission of the control information.

A first aspect of the present application provides an information scheduling method, in which a base station may configure a cross-carrier scheduling indication for a first carrier through a high-level signaling, where the cross-carrier scheduling indication includes a cross-carrier scheduling indication of a first type of control information and/or a cross-carrier scheduling indication of a second type of control information; therefore, the base station determines a corresponding target carrier according to the cross-carrier scheduling indication of the first type of control information and/or the cross-carrier scheduling indication of the second type of control information, and transmits the control information on the first carrier on the target carrier. Therefore, different cross-carrier scheduling instructions are flexibly configured for the first type of control information and/or the second type of control information through the base station, and therefore compromise between reliability and transmission delay of transmission of the control information can be achieved.

With reference to the first aspect of the present application, in a first implementation manner of the first aspect, the determining, by the base station, a corresponding target carrier according to the cross-carrier scheduling indication includes:

and the base station determines a target carrier corresponding to the first type of control information according to the carrier indicator in the first type of control information or determines a target carrier corresponding to the second type of control information according to the carrier indicator in the second type of control information. Thus, the corresponding target carrier may be notified by a carrier indicator in the control information.

In combination with the first aspect of the present application, in a second implementation form of the first aspect,

the base station configures the cross-carrier scheduling indication of the first type of control information as cross-carrier scheduling execution or configures the cross-carrier scheduling indication of the second type of control information as cross-carrier scheduling execution; then, the base station determines that the corresponding target carrier is a second carrier; and transmitting the first type of control information or the second type of control information on the second carrier. For example, if the base station configures the cross-carrier scheduling indication of the first type of control information to perform cross-carrier scheduling, the first type of control information is transmitted on the second carrier; if the base station configures the cross-carrier scheduling indication of the second type of control information to execute cross-carrier scheduling, the second type of control information is transmitted on the second carrier. In this implementation, if the first carrier is a low-frequency carrier and the second carrier is a high-frequency carrier, there is a larger transmission delay for transmitting the control information on the first carrier than for transmitting the control information on the second carrier. Therefore, by the implementation, the transmission of the first type of control information or the second type of control information on the second carrier can reduce the time delay of control information transmission. Similarly, in this implementation, if the first carrier is a high-frequency carrier and the second carrier is a low-frequency carrier, the reliability of transmitting the control information on the second carrier is higher than that of transmitting the control information on the first carrier. Different cross-carrier scheduling indications are adopted according to different scenes and requirements, and a compromise between transmission delay and reliability can be realized. Here, the low frequency carrier is a relative concept, and is used to indicate a cell or carrier or base station with a relatively low carrier frequency among a plurality of connected cells or carriers or base stations of the user equipment. Similarly, the high frequency carrier is used to indicate a cell or carrier or base station with a relatively high carrier frequency among a plurality of connected cells or carriers or base stations of the user equipment.

In combination with the first aspect of the present application, in a third implementation form of the first aspect,

the base station configures the cross-carrier scheduling indication of the first type of control information as not to execute cross-carrier scheduling or configures the cross-carrier scheduling indication of the second type of control information as not to execute cross-carrier scheduling; then, the base station determines that the corresponding target carrier is the first carrier; and transmitting the first type of control information or the second type of control information on the first carrier. For example, if the base station configures the cross-carrier scheduling indication of the first type of control information as not to perform cross-carrier scheduling, the first type of control information is transmitted on the first carrier; for another example, if the base station configures that the cross-carrier scheduling indication of the second type of control information is not to perform cross-carrier scheduling, the second type of control information is transmitted on the first carrier. In this implementation, if the first carrier is a low-frequency carrier and the second carrier is a high-frequency carrier, the reliability of the transmission of the control information on the first carrier is higher than that of the transmission of the control information on the second carrier. Therefore, by transmitting the first type of control information or the second type of control information on the first carrier in this implementation manner, reliability of control information transmission can be improved. Similarly, in this implementation, if the first carrier is a high-frequency carrier and the second carrier is a low-frequency carrier, the transmission delay for transmitting the control information on the first carrier is smaller than that for transmitting the control information on the first carrier. Different cross-carrier scheduling indications are adopted according to different scenes and requirements, and a compromise between transmission delay and reliability can be realized. Here, the low frequency carrier is a relative concept, and is used to indicate a cell or carrier or base station with a relatively low carrier frequency among a plurality of connected cells or carriers or base stations of the user equipment. Similarly, the high frequency carrier is used to indicate a cell or carrier or base station with a relatively high carrier frequency among a plurality of connected cells or carriers or base stations of the user equipment.

In combination with the first aspect of the present application, in a fourth implementation form of the first aspect,

the base station configures the cross-carrier scheduling indication of the first type of control information as cross-carrier scheduling execution, and configures the cross-carrier scheduling indication of the second type of control information as cross-carrier scheduling execution; then, the base station determines that the corresponding target carrier is a second carrier; and transmitting the first type of control information and the second type of control information on the second carrier. Similar to the third implementation manner of the first aspect, in this implementation manner, the reliability of control information transmission can be improved or the transmission delay can be reduced by transmitting the first type of control information and the second type of control information on the second carrier.

In combination with the first aspect of the present application, in a fifth implementation form of the first aspect,

the base station configures the cross-carrier scheduling indication of the first type of control information as not to execute cross-carrier scheduling, and configures the cross-carrier scheduling indication of the second type of control information as not to execute cross-carrier scheduling; then, the base station determines that the corresponding target carrier is the first carrier; and transmitting the first type of control information and the second type of control information on the first carrier. Similar to the second implementation manner of the first aspect, in this implementation manner, the transmission of the first type of control information and the second type of control information on the first carrier can reduce a time delay of control information transmission or improve reliability of transmission thereof.

In combination with the first aspect of the present application, in a sixth implementation form of the first aspect,

the base station configures the cross-carrier scheduling indication of the first type of control information as cross-carrier scheduling execution, and configures the cross-carrier scheduling indication of the second type of control information as cross-carrier scheduling non-execution; then, the base station determines that the target carrier corresponding to the first type of control information is a second carrier, and determines that the target carrier corresponding to the second type of control information is the first carrier; and transmitting the first type of control information on the second carrier and the second type of control information on the first carrier.

Specifically, refer to at least one of DCI format 2, 2C, 2D, and the like of the LTE system. Such control information is delay sensitive, so that transmission delay can be considered preferentially when scheduling transmission is performed.

With reference to the first aspect or any one of the first to seventh implementation manners of the first aspect, in a twelfth implementation manner of the first aspect, scrambling information corresponding to the first type of control information is different from scrambling information corresponding to the second type of control information. That is, the first type of control information and the second type of control information use different scrambling codes. Thus, the base station can identify which control information belongs to the first type of control information and which control information belongs to the second type of control information through scrambling information corresponding to the first type of control information and the second type of control information, and further configure corresponding cross-carrier scheduling indications for the first type of control information and the second type of control information.

The present application further provides an information scheduling method, which is executed by the base station 200 in fig. 3 during operation, and a flowchart thereof is shown in fig. 4.

401. The base station configures cross carrier scheduling indication for the first carrier, wherein the cross carrier scheduling indication comprises cross carrier scheduling indication of the first type of control information and/or cross carrier scheduling indication of the second type of control information.

It should be noted that the base station may configure a cross-carrier scheduling indication for the first carrier through a high-level signaling, where the cross-carrier scheduling indication includes a cross-carrier scheduling indication of the first type of control information and/or a cross-carrier scheduling indication of the second type of control information. The first type of control information is semi-persistent control information, wherein the semi-persistent control information is a type of control information that is not sensitive to delay (i.e., slow-varying, and tolerable to delay), and meanwhile, dynamic signaling can be performed on the type of control information when needed. And the second type of control information is dynamic control information, wherein the dynamic control information is delay-sensitive control information, and the second type of control information is used for transmission of the next data. The second type of control information is therefore a type of control information that is sensitive to latency (i.e., fast-changing).

It should be noted that the two types of control information correspond to different cross-carrier scheduling configuration signaling, that is, the first type of control information corresponds to the first cross-carrier scheduling indication, and the second type of control information corresponds to the second cross-carrier scheduling indication. The base station can configure different cross-carrier scheduling indications to different types of control information according to different scene assumptions and requirements.

Optionally, the content of the first type of control information may include: at least one of precoding information (e.g., uplink beam information), resource allocation information (e.g., sub-bandwidth scheduling information in a large bandwidth scenario), reference signal resource configuration information, subcarrier spacing, and subframe length configuration.

Wherein the precoding information specifically includes: at least one of the weighting coefficient matrix of the transmitting end, the weighting coefficient matrix information of the receiving end, the weighting coefficient matrix information of the transmitting end, and the weighting coefficient matrix set information of the transmitting end.

In addition, the information for cross-carrier transmission may also be some beam management related trigger signaling, such as some beam tracking trigger commands or beam repair trigger commands. Or some signaling for the start and end of Multiple shot CSI-RS transmission, and some signaling for reference signal resource configuration. And are not limited herein. The Multiple shot CSI-RS is defined as that one trigger corresponds to the sending and transmission of the CSI-RS for a plurality of times.

Still further, the precoding information may be a transmission beam of the user equipment and/or a reception beam of the base station; in addition, the precoding information may also be a transmission beam set of the user equipment.

Equivalently, the precoding information may be a transmission beam of the base station and/or a reception beam of the base station; in addition, the precoding information may also be a transmission beam set or a reception beam set of the base station.

The reference signal resource configuration information may optionally be reference signal resource configuration for beam management, where the beam management includes beam scanning, beam selection, beam repair, and other processes. Alternatively, the reference signal may be a beamformed reference signal.

The subcarrier spacing and subframe length configuration is used in a scenario where the first carrier simultaneously supports a configuration of greater than or equal to 2 subcarrier spacings and subframe lengths.

Optionally, the first type of control information may further include control information for random access channel scheduling, such as PDCCH order in LTE, and/or common control information for time-frequency resource allocation of a common channel. Wherein the common channel includes a data channel or a broadcast channel for transmitting system information. In addition, the channel or signal may be other than the common channel, and is not limited herein.

Optionally, the content of the second type of control information may include: at least one of time-frequency resource allocation, modulation coding format, redundancy version indication, new data indication, power control command word and Hybrid Automatic repeat Request (HARQ) process number for data transmission. Specifically, refer to at least one of Downlink Control Information (DCI) format 2, 2C, 2D, and the like of the LTE system.

Optionally, the scrambling information corresponding to the first type of control information is different from the scrambling information corresponding to the second type of control information. That is, the first type of control information and the second type of control information use different scrambling codes. Thus, the base station may identify which control information belongs to the first type of control information and which control information belongs to the second type of control information through scrambling information corresponding to the first type of control information and the second type of control information, and further determine the cross-carrier scheduling indication corresponding to the first type of control information and the second type of control information. The cross-carrier scheduling indication corresponding to the first type of control information and the second type of control information may be predefined or configured by the base station, and is not specifically limited herein.

Preferably, the first type of control information is scrambled by using a Semi-Persistent Scheduling Radio Network Temporary Identifier (SPS-RNTI), and the second type of control information is scrambled by using a Cell Radio Network Temporary Identifier (C-RNTI).

Optionally, a format of the control information corresponding to the first type of control information is the same as or different from a format of the control information corresponding to the second type of control information. For example, the first type of control information and the second type of control information may be located in one DCI format, or may be located in different DCI formats, which is not limited herein. Under the condition of the same DCI format, configuring first type control information and second type control information by a base station, and optionally distinguishing the two types of control information by different scrambling code information; under the condition of different DCI formats, the base station can identify which control information belongs to the first type of control information and which control information belongs to the second type of control information through the DCI formats corresponding to the first type of control information and the second type of control information, and further determine cross-carrier scheduling indications corresponding to the first type of control information and the second type of control information. The cross-carrier scheduling indication corresponding to the first type of control information and the second type of control information may be predefined or configured by the base station, and is not specifically limited herein.

402. And the base station determines a corresponding target carrier according to the cross-carrier scheduling indication.

Optionally, the determining, by the base station, a corresponding target carrier according to the cross-carrier scheduling indication includes:

and the base station determines a target carrier corresponding to the first type of control information according to the carrier indicator in the first type of control information or determines a target carrier corresponding to the second type of control information according to the carrier indicator in the second type of control information.

The carrier indicator is a field in the first type of control information or the second type of control information, and is used for determining a target carrier for transmitting the first type of control information or the second type of control information.

It should be noted that the cross-carrier scheduling indication configured for the terminal device by the base station is notified to the user through a high-level signaling. And the target carrier corresponding to each type of control information is notified to the user through a carrier indicator field in the control information. Other notification methods are not limited herein. The method of combining the high-level signaling configuration and the specific dynamic indication of the control information can realize the additional cross-carrier scheduling indication of each carrier and the corresponding target carrier.

403. And the base station transmits the control information on the first carrier on the target carrier.

For steps 402-403, reference may be made to several possible configurations as listed below:

the first scheme is as follows:

the base station configures the cross-carrier scheduling indication of the first type of control information as cross-carrier scheduling execution or configures the cross-carrier scheduling indication of the second type of control information as cross-carrier scheduling execution;

the base station determines a corresponding target carrier according to the cross-carrier scheduling indication, and the method comprises the following steps:

the base station determines that the corresponding target carrier is a second carrier;

the base station transmits the control information on the first carrier on the target carrier, and the method comprises the following steps:

and the base station transmits the first type of control information or the second type of control information on the second carrier.

Scheme II:

the base station configures the cross-carrier scheduling indication of the first type of control information as not to execute cross-carrier scheduling or configures the cross-carrier scheduling indication of the second type of control information as not to execute cross-carrier scheduling;

the base station determines a corresponding target carrier as the first carrier;

and the base station transmits the first type of control information or the second type of control information on the first carrier.

The third scheme is as follows:

the base station configures the cross-carrier scheduling indication of the first type of control information as cross-carrier scheduling execution, and configures the cross-carrier scheduling indication of the second type of control information as cross-carrier scheduling execution;

and the base station transmits the first type of control information and the second type of control information on the second carrier.

And the scheme is as follows:

the base station configures the cross-carrier scheduling indication of the first type of control information as not to execute cross-carrier scheduling, and configures the cross-carrier scheduling indication of the second type of control information as not to execute cross-carrier scheduling;

and the base station transmits the first type of control information and the second type of control information on the first carrier.

And a fifth scheme:

the base station configures the cross-carrier scheduling indication of the first type of control information as cross-carrier scheduling execution, and configures the cross-carrier scheduling indication of the second type of control information as cross-carrier scheduling non-execution;

the base station determines that a target carrier corresponding to the first type of control information is a second carrier and determines that a target carrier corresponding to the second type of control information is the first carrier;

the base station transmits the first type of control information on the second carrier and transmits the second type of control information on the first carrier.

Scheme six:

the base station configures the cross-carrier scheduling indication of the first type of control information as not to execute cross-carrier scheduling, and configures the cross-carrier scheduling indication of the second type of control information as to execute cross-carrier scheduling;

the base station determines that a target carrier corresponding to the first type of control information is the first carrier and determines that a target carrier corresponding to the second type of control information is the second carrier;

the base station transmits the first type of control information on the first carrier and transmits the second type of control information on the second carrier.

For example, when the transmission requirement of the control information of the user is low latency, the cross-carrier scheduling indication of the first type of control information may be configured to be "no", and the cross-carrier scheduling indication of the second type of control information may be configured to be "no". Here, "yes" indicates that cross-carrier scheduling is performed, and "no" indicates that cross-carrier scheduling is not performed. The base station determines that the target carrier corresponding to the first type of control information is the first carrier (i.e. the carrier scheduled by the cross carrier) according to the fact that the cross carrier scheduling indication of the first type of control information is 'no', and determines that the target carrier corresponding to the second type of control information is also the first carrier (i.e. the carrier scheduled by the cross carrier) according to the fact that the cross carrier scheduling indication of the second type of control information is 'no'. Thus, the base station transmits the first type of control information and the second type of control information on said first carrier. And when the control information transmission requirement of the user is high reliability, the cross-carrier scheduling indication of the first type of control information can be configured to be 'yes', and the cross-carrier scheduling indication of the second type of control information is 'no'. The base station determines that the target carrier corresponding to the first type of control information is the second carrier (namely, the carrier scheduled by the cross carrier) according to the yes of the cross carrier scheduling indication of the first type of control information, and determines that the target carrier corresponding to the second type of control information is the first carrier (namely, the carrier scheduled by the cross carrier) according to the no of the cross carrier scheduling indication of the second type of control information. Thus, the base station transmits control information of the first type on the second carrier and control information of the second type on the first carrier.

In the information scheduling method provided by the embodiment of the application, a base station configures cross-carrier scheduling indication of first type control information and/or cross-carrier scheduling indication of second type control information for a first carrier; the base station determines a corresponding target carrier according to the cross-carrier scheduling indication of the first type of control information and/or the cross-carrier scheduling indication of the second type of control information; and transmitting control information on the first carrier on the target carrier. Therefore, the base station flexibly configures different cross-carrier scheduling indications for the first type of control information and/or the second type of control information, so that a compromise between reliability and transmission delay of transmission of the control information can be realized.

In addition, the cross-carrier scheduling indication may also be used for cross-carrier transmission of uplink control information, where the uplink control information includes: HARQ, ACK/NACK, CSI (including CRI (CSI-RS Resource Index), RI (Rank Indication), PMI (Precoding Matrix Indication), CQI (Channel quality Indication), etc.). The cross-carrier scheduling indication of the uplink control information may be notified to the ue by the base station through a higher layer signaling, such as an RRC signaling.
