Description

Deactivation method, device and equipment for channel state information feedback

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a method, an apparatus, and a device for deactivating channel state information feedback.

Background

A New air interface (NR, New Radio) supports a semi-persistent (SP) Channel State Information (CSI) feedback mode, as shown in fig. 1. The start and termination of the CSI feedback is signaled to the terminal by the network side through activation and deactivation signaling. After receiving the activation signaling, the User Equipment (UE), which may also be referred to as a terminal, performs feedback according to a period (denoted as P in fig. 1) configured by the network side until receiving the deactivation signaling. The feedback of the SP-CSI may be fed back on a Physical Uplink Control Channel (PUCCH) or on a Physical Uplink Shared Channel (PUSCH), and may be indicated by using different signaling. The SP-CSI feedback based on the PUCCH indicates activation and deactivation using a Media Access Control (MAC) Control Element (CE), and the SP-CSI feedback based on the PUSCH indicates activation and deactivation using Downlink Control Information (DCI).

The NR system may configure a plurality of SP-CSI trigger states, where one SP-CSI trigger state corresponds to one SP-CSI report (i.e., one reporting setting defined in TS 38.214). For PUSCH-based SP-CSI, one DCI signaling may activate one SP-CSI trigger state. The DCI related to the uplink channel includes two formats, DCI format 0_0 and DCI format 0_ 1. Each DCI format includes a plurality of information fields, such as a Hybrid Automatic Repeat reQuest (HARQ) process number information field, a modulation and coding scheme information field, a time domain resource allocation field, a frequency domain resource allocation field, a new data indication field, a redundancy version information field, and a transmission Power command tpc (transmission Power command) field for scheduling PUSCH. Different from format 0_0, DCI format 0_1 further includes a CSI request field whose value may indicate any one SP-CSI trigger state of a plurality of SP-CSI trigger states configured by the system. Since DCI format 0_0 does not contain this CSI request field, it cannot indicate a certain SP-CSI trigger state. Thus DCI format 0_1 is used in NR and bits of HARQ process number field and redundancy version field are set to all zeros for indicating activation of PUSCH based SP-CSI.

Based on the different DCI formats, for a scene in which a plurality of SP-CSI trigger states are simultaneously in an activated state, if the DCI format 0_0 is adopted for deactivation, because a CSI request domain does not exist in the format 0_0, one SP-CSI trigger state cannot be deactivated, and the flexibility is poor; if the DCI format 0_1 is deactivated, since one DCI can only deactivate one SP-CSI trigger state, multiple DCI indications are required to deactivate the activated SP-CSI trigger states, which increases signaling overhead.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

In order to solve the problem of an NR system, when the PUSCH-based SP-CSI feedback uses DCI to indicate activation and deactivation, if the DCI format 0_0 is adopted for deactivation, one SP-CSI trigger state cannot be deactivated, and the flexibility is poor; and if the DCI format 0_1 is adopted for deactivation, only one SP-CSI trigger state can be deactivated, and when a plurality of activated SP-CSI trigger states are deactivated, a plurality of DCI indications are required, so that the signaling overhead is increased.

The method, the device and the equipment for deactivating the channel state information feedback provided by the embodiment of the invention can be applied to a wireless communication system. The wireless communication system may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent lte communication system. Fig. 2 is a schematic diagram of a wireless communication system according to an embodiment of the present invention. As shown in fig. 2, the wireless communication system may include: the network side device 10 and the user equipment, for example, the user equipment is denoted as UE 11, and the UE 11 may be communicatively connected to the network side device 10. In practical applications, the connections between the devices may be wireless connections, and fig. 2 illustrates solid lines for convenience and convenience in intuitively representing the connection relationships between the devices.

It should be noted that the communication system may include a plurality of UEs, and the network side device may communicate (transmit signaling or transmit data) with the plurality of UEs.

The network side device 10 provided in the embodiment of the present invention may be a base station, which may be a commonly used base station, an evolved node base station (eNB), or a network side device in a 5G system (for example, a next generation base station (gNB) or a Transmission and Reception Point (TRP)) or a cell, and the like.

The user equipment provided by the embodiment of the invention can be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA) and the like.

One embodiment of the method for deactivating CSI feedback according to the embodiment of the present invention is applied to network side setting, and as shown in fig. 3, the method includes:

s310, downlink control information DCI for deactivating feedback of semi-persistent channel state information SP-CSI is sent to user equipment; the DCI is a first format including a Channel State Information (CSI) request field or a second format not including the CSI request field;

The CSI feedback deactivation method according to the embodiment of the present invention, a DCI sent to a user equipment for deactivating SP-CSI feedback may be a first format including a CSI request field or a second format not including the CSI request field, where when the DCI is the first format, it is indicated to deactivate SP-CSI feedback corresponding to the CSI request field in the DCI, and when the DCI is the second format, it is indicated to deactivate all SP-CSI feedback in an activated state, or it is also indicated to deactivate all SP-CSI in an activated state, where one SP-CSI feedback is deactivated.

Therefore, according to the method for deactivating the CSI feedback, the DCI can indicate to deactivate one SP-CSI feedback and also indicate to deactivate all SP-CSI feedbacks in the activated state, so that the requirements of ensuring the flexibility of deactivation and reducing the signaling overhead are met.

In the embodiment of the present invention, the DCI in the first format may be, but is not limited to, the DCI in format 0_1 in the NR standard, and the DCI in the second format may be, but is not limited to, the DCI in format 0_0 in the NR standard, as long as one of the formats includes a CSI request field and the other format does not include a CSI request field is satisfied, which both conform to the definitions of the first format and the second format in the present invention.

For clearly explaining the CSI feedback deactivation method according to the embodiment of the present invention, the DCI in format 0_1 is the DCI in the first format in the present invention, and the DCI in format 0_0 is the DCI in the second format in the present invention, which are taken as examples, the CSI feedback deactivation method according to the embodiment of the present invention will be described in detail below.

In addition, it should be noted that, in the embodiment of the present invention, one SP-CSI feedback may be one SP-CSI trigger state, where the one SP-CSI trigger state includes one or more SP-CSI reports; one SP-CSI feedback may also be one SP-CSI report. In addition, one SP-CSI report corresponds to one report setting in the standard protocol TS 38.214.

In one implementation manner of the embodiment of the present invention, in step S310, the DCI for deactivating SP-CSI feedback sent to the user equipment has a specific information field, which is used to indicate that the DCI is for deactivating SP-CSI feedback.

It can be understood that the DCI of format 0_0 and the DCI of format 0_1 respectively include a plurality of information fields, such as a HARQ process number information field, a modulation and coding scheme information field, a time domain resource allocation field, a frequency domain resource allocation field, a new data indication field, a redundancy version information field, and a TPC command field for scheduling PUSCH, and in the embodiment of the present invention, one or at least two of the information fields are configured as specific information fields mentioned in the embodiment of the present invention.

In this embodiment of the present invention, the specific information field in the DCI in the first format (format 0_1) and the specific information field in the DCI in the second format (format 0_0) may be the same or different.

For example, the specific information fields of the DCI having the format 0_1 and the DCI having the format 0_0 may be configured as the time domain resource allocation field and the frequency domain resource allocation field, respectively, or the specific information fields of the DCI having the format 0_1 may be configured as the time domain resource allocation field and the frequency domain resource allocation field, and the specific information fields of the DCI having the format 0_0 may be configured as the modulation and coding scheme information field, the time domain resource allocation field, the frequency domain resource allocation field, and the new data indication field.

On the other hand, in step S310, when the DCI is in the second format, the specific information field is further used to indicate that the SP-CSI feedback indicated by the specific information field is deactivated. The SP-CSI indicated by the specific information field is all SP-CSI feedback in an activated state, or one of the SP-CSI feedback in all the SP-CSI feedback in the activated state.

That is, based on the foregoing manner, when the DCI is in the second format (format 0_0), all SP-CSI feedbacks in the active state may be deactivated through the specific information field indication, and also one of the SP-CSI feedbacks in the active state may be deactivated through the specific information field indication, so as to ensure the flexibility of deactivation and achieve the effect of reducing signaling overhead.

In this embodiment of the present invention, when the DCI is in the second format (format 0_0), the specific information field for indicating that all SP-CSI feedbacks in the active state are deactivated is the same as or different from the specific information field for indicating that one SP-CSI feedback is deactivated in the SP-CSI feedbacks in the active state.

In another aspect of the embodiment of the present invention, in step S310, when the DCI is in the second format (format 0_0), the DCI in the second format is directly used to indicate that the DCI is used to deactivate SP-CSI feedback, and all the SP-CSI feedbacks in the activated state are deactivated.

That is, based on this embodiment, all of the SP-CSI feedback in the active state can be deactivated directly through the DCI of format 0_ 0.

Based on the CSI feedback deactivation method according to the embodiment of the present invention, when all SP-CSI feedbacks in the activated state are deactivated, one of the following manners may be adopted:

direct indication by DCI of a second format;

indicated by a specific information field in the DCI of the second format.

When one of the activated SP-CSI feedbacks is deactivated, one of the following manners may be adopted:

indicating, by the DCI of the first format, that SP-CSI feedback indicated to need deactivation corresponds to a CSI request field in the DCI indication;

indicated by a specific information field in the DCI of the second format.

When the DCI in the first format (format 0_1) indicates that all SP-CSI feedbacks in an active state are deactivated, each information field in a specific information field included in the DCI has a corresponding preset bit value, and the preset bit values of each information field in the specific information field are combined into a first specific information value, where the first specific information value is used to indicate that the DCI is used to deactivate the SP-CSI feedback.

Specifically, the network side device indicates that the DCI is used for deactivating SP-CSI feedback and deactivates the SP-CSI feedback corresponding to the CSI request field by determining an information bit value of the CSI request field in DCI format 0_1 and configuring a bit value of each information field included in a specific information field in the DCI as a corresponding preset bit value.

For example, if there are K SP-CSI trigger states in active state (i.e. there are K SP-CSI feedbacks in active state) in the system at the same time, K > -1. According to step S310, the network side device sends DCI of format 0_1 to the user equipment;

in the sent DCI with the format 0_1, determining an information bit value of a CSI request field of the DCI with the format 0_1, corresponding to the ith SP-CSI trigger state in the K SP-CSI trigger states, configuring a bit value of each information field included in a specific information field in the DCI into a corresponding preset bit value, indicating that the DCI is used for deactivating SP-CSI feedback, and indicating that the ith SP-CSI trigger state is deactivated.

In this embodiment, the information fields included in a specific information field in the DCI of format 0_1, and the preset bit value of each information field may be determined by pre-definition, or may be transmitted to the user equipment through higher layer signaling.

When the DCI in the second format (format 0_0) directly indicates that all SP-CSI feedback in the active state is deactivated, bit information of all information fields in the DCI is determined by the network side device.

For example, if there are K SP-CSI trigger states in active state (i.e. there are K SP-CSI feedbacks in active state) in the system at the same time, K > -1. According to step S310, the network side device sends DCI of format 0_0 to the user equipment; as can be understood, the DCI is scrambled by the SP-CSI C-RNTI and then sent to the user equipment;

the terminal receives and detects DCI sent by network side equipment, and when the DCI is determined to be the DCI with the format of 0_0 after being scrambled by SP-CSI C-RNTI, all K SP-CSI feedbacks in the activated state are deactivated.

When the specific information field in the DCI of the second format (format 0_0) indicates that all SP-CSI feedback in the active state is deactivated, each information field in the specific information field corresponding to the DCI has a corresponding preset bit value, and the preset bit values of each information field in the specific information field are combined into a second specific information value, where the second specific information value is used to indicate that the DCI is used to deactivate SP-CSI and deactivate all SP-CSI feedback in the active state.

Specifically, the system predefines one or more information fields in the DCI of format 0_0 as specific information fields, and predefines a preset bit value of each information field in the specific information fields, which are combined to form a second specific information value for indicating that the DCI of format 0_0 is used to indicate that all the activated SP-CSI feedback is deactivated.

For example, if there are K SP-CSI trigger states in active state (i.e. there are K SP-CSI feedbacks in active state) in the system at the same time, K > -1. According to step S310, the network side device sends DCI of format 0_0 to the user equipment; it can be appreciated that the DCI is sent to the user equipment after being scrambled by the SP-CSI C-RNTI.

In addition, before step S310, the HARQ process number field, the modulation and coding scheme field, the time domain resource allocation field, the frequency domain resource allocation field, and the redundancy version field in the DCI of format 0_0 may be predefined by the system as corresponding specific information fields, in addition, the bit values respectively corresponding to the predefined HARQ process number field and the redundancy version field are all 0 (formed as respectively corresponding preset bit values), the bit values of the modulation and coding scheme field, the time domain resource allocation field, and the frequency domain resource allocation field are all 1 (formed as respectively corresponding preset bit values), and the bit combination constitutes a second specific information value for indicating the deactivation of the SP-CSI feedback.

Based on the above determination process, in step S310, the preset bit value of each information field in the specific information field of the DCI of format 0_0 being transmitted is combined into a second specific information value, which indicates to deactivate all SP-CSI trigger states in the active state.

And when the terminal receives and detects the DCI sent by the network side equipment, the DCI is determined to be the DCI with the format 0_0 scrambled by the SP-CSI C-RNTI and the specific information field is the second specific information value, all K SP-CSI trigger states in the activated state are deactivated.

When one of the SP-CSI feedbacks is deactivated by the indication of the specific information field in the DCI in the second format (format 0_0), each information field in the specific information field corresponding to the DCI has a corresponding preset bit value, and the preset bit values of each information field in the specific information field are combined into a third specific information value, where the third specific information value is used to indicate that the DCI is used to deactivate SP-CSI and deactivate the SP-CSI feedback having a pre-corresponding relationship with the third specific information value.

Specifically, different third specific information values of a specific information field have a pre-correspondence with different SP-CSI feedbacks.

With this embodiment, one or at least two information fields in the DCI of format 0_0 may be determined to be specific information fields in a predefined manner, and the pre-correspondence between different third specific information values in the specific information fields and different SP-CSI feedbacks is predefined or indicated through higher layer signaling.

For example, if there are K SP-CSI trigger states in active state (i.e. there are K SP-CSI feedbacks in active state) in the system at the same time, K > -1. According to step S310, the network side device sends DCI of format 0_0 to the user equipment; it can be understood that the DCI is sent to the user equipment after being scrambled by the SP-CSI C-RNTI.

In addition, before step S310, the specific information field of the DCI may be the HARQ process number field, the modulation coding scheme field, the time domain resource allocation field, the frequency domain resource allocation field, and the redundancy version field in the DCI with the predefined format 0_0 by the system, when the specific information field has N bits in total, the system predefines that all the N bits take values as 0, and may correspond to the 0 th SP-CSI feedback, and when all the first N-1 bits take values as 0 and only 1 bit takes values as 1, the system may correspond to the 1 st SP-CSI feedback, and in this order, when all the N bits take values as 1, the system corresponds to the 2 nd SP-CSI feedback ^N -1 SP-CSI feedback. According to the example, different third specific information values can correspond to different SP-CSI feedbacks and are used for indicating to deactivate the corresponding SP-CSI feedback.

By adopting the above mode, the network side device determines the bit value of the specific information field in the DCI of format 0_0 to be sent, so that the bit value corresponds to the ith SP-CSI feedback in the K SP-CSI feedbacks, and instructs to deactivate the ith SP-CSI feedback.

And when the terminal receives and detects the DCI sent by the network side equipment after the transmission delay delta time, determining the DCI as being used for indicating to deactivate the ith SP-CSI feedback according to the pre-corresponding relation between the pre-acquired different third specific information values and the pre-acquired different SP-CSI feedbacks.

On the other hand, by adopting the CSI feedback deactivation method according to the embodiment of the present invention, different DCIs can be sent for multiple times to deactivate different orders of multiple SP-CSI feedbacks.

For example, if there are K SP-CSI trigger states in active state (i.e. there are K SP-CSI feedbacks in active state) in the system at the same time, K > -1.

The system predefines the specific information domain corresponding to the DCI in the HARQ process number domain, the modulation coding scheme domain, the time domain resource allocation domain, the frequency domain resource allocation domain and the redundancy version domain in the DCI of format 0_ 1. And the bits in the predefined HARQ process number domain and the redundancy version domain take the values of all 0 (preset bit values), the bits in the modulation coding scheme domain, the time domain resource allocation domain and the frequency domain resource allocation domain take the values of all 1 (preset bit values), and the bit combination is used as a first specific information value for indicating the deactivation of the DCI with the format 0_1 on the SP-CSI feedback.

The system predefines the HARQ process number field, the modulation coding scheme field, the time domain resource allocation field, the frequency domain resource allocation field and the redundancy version field in the DCI format 0_0 as the specific information field corresponding to the DCI. And the bits in the predefined HARQ process number domain and the redundancy version domain take the values of all 0 (preset bit values), the bits in the modulation coding scheme domain, the time domain resource allocation domain and the frequency domain resource allocation domain take the values of all 1 (preset bit values), and the bit combination is used as a second specific information value for indicating the deactivation of all SP-CSI in an activated state.

And the network side equipment determines the information bit value of the CSI request domain of the DCI with the format 0_1, so that the information bit value of the CSI request domain corresponds to the ith SP-CSI trigger state in the K SP-CSI trigger states. Configuring a bit value of a specific information domain of the DCI into a first specific information value, and indicating that the ith SP-CSI trigger state is deactivated;

based on the determination process, the network side device may configure the bit value of the specific information field as DCI of a first specific information value format 0_1, and transmit the DCI to the user equipment at time n after scrambling by the SP-CSI C-RNTI;

then, the network side equipment adopts DCI with the format 0_0, configures bit values of a specific information domain of the DCI into second specific information values, scrambles the second specific information values through SP-CSI C-RNTI, and sends the second specific information values to the user equipment at the time n + m, wherein the second specific information values are used for indicating that all the remaining K-1 SP-CSI trigger states in the activated state are deactivated;

and the terminal receives and detects the DCI sent by the network side equipment at the time n + delta, wherein delta represents the transmission delay. Determining that the DCI is a DCI format 0_1 scrambled by SP-CSI C-RNTI and the specific information field is a first specific information value, and then the terminal deactivates the ith SP-CSI trigger state according to the indication of the CSI request field in the DCI;

and the terminal receives and detects the DCI signaling sent by the network side equipment at the time n + m + delta, determines that the DCI signaling is the DCI with the format 0_0 scrambled by the SP-CSI C-RNTI, and deactivates all K-1 SP-CSI trigger states in the activated state if the specific information field is the second specific information value.

According to the above detailed description, it can be seen that, by using the method for deactivating CSI feedback according to the embodiment of the present invention, it is possible to instruct to deactivate one of the SP-CSI feedbacks through the DCI, and also instruct to deactivate all SP-CSI feedbacks in the activated state, thereby meeting the requirements of simultaneously ensuring the flexibility of deactivation and reducing the signaling overhead.
