Description

Method, terminal, base station, medium and system for acquiring and indicating transmission position
Technical Field
The embodiment of the invention relates to the field of communication, in particular to a method, a terminal, a base station, a medium and a system for acquiring and indicating a transmission position.
Background
A Physical Uplink Control Channel (PUCCH) is one Physical Channel of an Uplink in an NR (New Radio, NR) system, and is used to carry Uplink Control information. The purpose of setting the PUCCH is: when a User is not scheduled, that is, when no Uplink Shared Channel (UL-SCH) resource is allocated, a terminal (User Equipment, UE) transmits control information of Layer1 or Layer 2(Layer1/Layer2, L1/L2) including a Channel state report, such as a Precoding Matrix Indicator (PMI), a Channel Quality Indicator (CQI), etc., a Hybrid Automatic Repeat reQuest (HARQ) acknowledgement and a scheduling reQuest, using a PUCCH.
To support unlicensed spectrum, 3GPP introduced a Listen-Before-Talk mechanism (Listen-Before-Talk, LBT). In the LBT process, before data is transmitted in the unlicensed spectrum, first, Clear Channel Assessment (CCA) is performed to determine whether a current Channel is available, that is, whether the Channel is occupied is determined by energy detection (energy detection), and when received energy exceeds a preset threshold, the Channel is considered to be busy. Meanwhile, the 3GPP supports two channel access processes, which are respectively: type1 and Type2, where Type1 is channel access based on capability 4(Category 4, Cat 4), and Type2 is channel access based on fixed time length, i.e. LBT at least 25 μ s before data transmission.
In the existing LBT access process, because CCA is required, the starting symbol and length of actually transmitting PUCCH in an unlicensed cell may be different from the starting symbol and length of PUCCH configured by a high-level signaling, so that UE cannot transmit PUCCH according to the starting symbol and length of PUCCH configured by the high-level signaling, and cannot normally communicate.

Detailed Description
In the existing LBT access process, because CCA is required, the starting symbol and length of actually transmitting PUCCH in an unlicensed cell may be different from the starting symbol and length of PUCCH configured by a high-level signaling, so that UE cannot transmit PUCCH according to the starting symbol and length of PUCCH configured by the high-level signaling, and cannot normally communicate.
The embodiment of the invention receives the RRC signaling sent by the base station, wherein the RRC signaling comprises the following steps: and then determining the starting symbol and the length of the PUCCH based on the RRC signaling, so that the UE can send the PUCCH to the base station, and the base station can acquire the PUCCH, thereby realizing normal communication.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a flowchart of a method for acquiring a transmission location, which may include the following steps:
step S101, receiving RRC signaling sent by a base station, wherein the RRC signaling comprises: a starting symbol offset set of PUCCH and an ending symbol offset set of PUCCH.
In a specific implementation, the RRC signaling may include: configuration information of PUCCH resources. The configuration information of the PUCCH Resource may include information such as a PUCCH format, a PUCCH start symbol and length, a PUCCH start Physical Resource Block (PRB) frequency position, a PUCCH frequency domain PRB number, whether frequency hopping is performed, a PUCCH second hop PRB frequency position, and a code rate.
In a specific implementation, due to CCA, a starting symbol and a length of a PUCCH actually transmitted by a UE in an unlicensed spectrum cell may be different from a starting symbol and a length of a PUCCH configured by RRC signaling, so that the UE cannot transmit the PUCCH according to the starting symbol and the length of the PUCCH configured by higher layer signaling. Therefore, in the embodiment of the present invention, the starting symbol and length of the PUCCH may be determined through RRC signaling sent by the base station.
In a specific implementation, when the PUCCH is configured to be transmitted in the unlicensed spectrum cell, the RRC signaling may include: a PUCCH starting symbol offset set and an ending symbol offset set, wherein the starting symbol offset is used for indicating a time offset for the PUCCH to really start transmitting relative to a starting symbol of the PUCCH; the end symbol offset is used to indicate a time offset at which the PUCCH really ends transmission relative to the end symbol of the PUCCH. Through the starting symbol offset and the ending symbol offset, the symbol length of the PUCCH can be derived and known, for example, the symbol length of the PUCCH is a difference between a time offset when the PUCCH really ends transmission and a time offset when the PUCCH really starts transmission, which is not described herein again.
In a specific implementation, the starting symbol offset set of the PUCCH may include one offset value, or may include multiple (more than two) offset values.
In a specific implementation, the end symbol offset set of the PUCCH may include one offset value, or may include multiple (more than two) offset values.
In a specific implementation, when the PUCCH is a periodic resource, the starting symbol offset set of the PUCCH and the ending symbol offset set of the PUCCH may include 1 offset value.
In a specific implementation, the base station may trigger or activate the PUCCH through DCI signaling. Therefore, when the starting symbol offset set of the PUCCH includes multiple offset values, the base station may indicate a specific offset value through DCI signaling, that is, a starting symbol time offset at which transmission of the PUCCH really starts; when the end symbol offset set of the PUCCH includes a plurality of offset values, the base station may indicate a specific offset value, i.e., an end symbol time offset at which transmission of the PUCCH really starts, through DCI signaling.
Step S102, based on the RRC signaling, determining the starting symbol and length of the PUCCH.
In an embodiment of the present invention, when at least one of the starting symbol offset set of the PUCCH or the ending symbol offset set of the PUCCH includes a plurality of offset values, the determining the starting symbol and the length of the PUCCH includes: receiving a DCI signaling sent by the base station, wherein the DCI signaling comprises: a trigger indication of the PUCCH, a starting symbol offset of the PUCCH, and an ending symbol offset of the PUCCH; determining a starting symbol and length of a PUCCH based on the RRC signaling and the DCI signaling.
In an embodiment of the present invention, log in the DCI signaling when at least one of M, N is greater than 12(M x N) bits are used to indicate a starting symbol offset of the PUCCH and an ending symbol offset of the PUCCH, where M is the number of offset values in the starting symbol offset set of the PUCCH and N is the number of offset values in the ending symbol offset set of the PUCCH.
For example, the starting symbol offset set of PUCCH contains 4 configuration values, as follows:
–+TA
–+25μs
–+1symbol
-No offset (No offset)
The physical meaning corresponding to the starting symbol offset set of the PUCCH is as follows: relative to the starting symbol of the PUCCH, the time when the PUCCH really starts to transmit and the starting symbol interval of the PUCCH are a duration of one transmission, 25 μ s, a duration corresponding to 1 symbol, and 0, respectively.
The end symbol offset set of PUCCH contains 2 configuration values, as follows:
–No offset
–1symbol
the physical meaning corresponding to the above PUCCH end symbol offset set is: relative to the end symbol of the PUCCH, the time for the PUCCH to actually end transmission and the end symbol interval of the PUCCH are duration and 0 corresponding to 1 symbol, respectively.
Then 3 bits in the DCI signaling are used to indicate the starting symbol offset of the PUCCH and the ending symbol offset of the PUCCH.
In an embodiment of the present invention, when M is greater than 1, log in the DCI signaling2M bits are used to indicate a starting symbol offset of the PUCCH; when N is greater than 1, log2N bits in the DCI signaling are used to indicate an end symbol offset of the PUCCH, where M is the number of offset values in a starting symbol offset set of the PUCCH and N is the number of offset values in an end symbol offset set of the PUCCH.
For example, the starting symbol offset set of PUCCH contains 4 configuration values, as follows:
–+TA
–+25μs
–+1symbol
-No offset (No offset)
The physical meaning corresponding to the starting symbol offset set of the PUCCH is as follows: relative to the starting symbol of the PUCCH, the time when the PUCCH really starts to transmit and the starting symbol interval of the PUCCH are a duration of one transmission, 25 μ s, a duration corresponding to 1 symbol, and 0, respectively.
The end symbol offset set of PUCCH contains 2 configuration values, as follows:
–No offset
–1symbol
the physical meaning corresponding to the above PUCCH end symbol offset set is: relative to the end symbol of the PUCCH, the time for the PUCCH to actually end transmission and the end symbol interval of the PUCCH are duration and 0 corresponding to 1 symbol, respectively.
Then 2 bits in the DCI signaling are used to indicate a starting symbol offset of the PUCCH and 1 bit in the DCI signaling is used to indicate an ending symbol offset of the PUCCH.
In a specific implementation, when the PUCCH is triggered or activated through DCI signaling, the DCI signaling may further include: and channel access mode of PUCCH.
In a specific implementation, the channel access method of the PUCCH includes: type1 and Type2, wherein Type1 is channel access based on capability 4, and Type2 is channel access based on fixed time length, i.e. LBT of at least 25 μ s before data transmission.
In an embodiment of the present invention, the channel access method of the PUCCH includes any one of: the channel access mode based on Cat 4 is based on the channel access mode with fixed time length.
In an example of the present invention, as shown in fig. 2, the access procedure of Type2 may include the following steps:
step S201, initializing N ═ Ninit。
In the detailed description，NinitCan be 0 to CWpRandom number in between, CWpIs a preset value.
In step S202, when N > 0, the counter value is decreased, i.e., N — 1.
Step S203, detecting the channel state in the first preset time length, and judging whether the channel state in the first preset time length is idle; step S204 is executed when the channel is idle within the first preset duration, otherwise step S205 is executed.
In a specific implementation, the first preset duration may be an additional slot duration (additional slot duration).
In step S204, it is determined whether N is 0, and if N is 0, step S207 is executed, otherwise step S202 is executed.
Step S205, detecting a channel state within a second preset time period.
In a specific implementation, the second preset duration may be an additional delay duration (additional duration) Td。
Step S206, determining whether the channel state within the second preset duration is idle, and if the channel state within the second preset duration is idle, executing step S202, otherwise executing step S205.
Step S207, the detection is stopped.
In a specific implementation, the access procedure of Type1 includes the following steps: when it is detected that at least the average energy of the third preset duration is lower than the preset threshold and the transmission time is less than 1ms, uplink or downlink data can be sent in a channel transmitted by the unlicensed cell.
In a specific implementation, the third preset time period Tdrs＝25us。
By applying the above scheme, the RRC signaling sent by the base station is received, where the RRC signaling includes: and then determining the starting symbol and the length of the PUCCH based on the RRC signaling, so that the UE can send the PUCCH to the base station, and the base station can acquire the PUCCH, thereby realizing normal communication.
