Description

Uplink data transmission method, configuration method and device for uplink data transmission

Technical field

The present invention relates to the field of communications, and in particular, to an uplink data transmission method, a configuration method, and a device for uplink data transmission.

Background technique

Listen Before Talk (LBT) is a channel access mechanism that enables wireless LANs to effectively share the same spectrum resources. Because the availability of the channel on the unlicensed band cannot be guaranteed at all times, LBT requires that the device monitor the channel before sending data, perform an idle channel assessment, and then send data when the channel is free.

In the Long Term Evolution (LTE) Licensed Assisted Access (LAA), a random backoff LBT (LBT with random back-off with variable content size of content window) with a non-fixed contention window size is used. That is, the channel access process of the sending device includes random back-off, and the size of the corresponding contention window (CW) can be adjusted. In random backoff, the sending user equipment separately evaluates whether the channel is idle by detecting the channel energy according to a random back-off counter (counter) in each time interval. If the channel is idle in a time interval, the counter (counter N) is decremented by 1 until the counter (N) is 0, the transmitting device considers that the channel is free and can start sending uplink data on the channel. In the above mechanism, the initial value of the random backoff counter may be an integer between 0 and CWS / CWV, CWS is the contention window size (Contention Window Size), and CWV is the contention window value (Contention Window Value).

The transmitting device can adjust the CWV before initializing the random backoff counter. For uplink channel evaluation, the sending device is User Equipment (UE). If the UE receives an uplink grant (UL grant) or AUL-DFI (Autonomous Downlink feedback indication), the UE determines the indication according to UL grant or AUL-DFI. The transmission situation of the HARQ process corresponding to the reference subframe (s) of a certain carrier, and the transmission situation reflects the channel state to a certain extent. For example, if it is determined that at least one of the HARQ processes is successfully transmitted, the CWV of all channel access priorities of the corresponding carrier is set to the minimum value in the CWV set of the corresponding priority; otherwise, it is increased to the CWV set of corresponding priority The next value.

It should be noted that the above description of the technical background is merely for the convenience of a clear and complete description of the technical solution of the present invention, and for the understanding of those skilled in the art. The above technical solutions should not be considered to be well known to those skilled in the art just because these solutions are explained in the background section of the present invention.

Summary of the invention

The inventor found that in LAA, one carrier corresponds to one channel. One uplink carrier is configured with a set of contention windows, where each contention window corresponds to a priority and has a contention value (CWV) set. The user equipment may perform channel access using a contention window (CW) corresponding to the carrier to send uplink data on the carrier. In addition, the user equipment may adjust the CW corresponding to the carrier according to the reception condition of the uplink data sent by the carrier.

However, in New Radio (NR), at different times, the UE may transmit data on a part of the bandwidth of different frequency domain positions of the same carrier. For unlicensed frequency bands, if a carrier corresponds to two or more channels (one channel is, for example, 20 MHz) and supports switching between a part of the bandwidth in different frequency domain positions in the carrier, the channel corresponding to a part of the bandwidth before the switch The channels corresponding to the latter part of the bandwidth may be different. Therefore, the reception of data sent on a part of the bandwidth before the handover is not necessarily related to the channel state of the channel corresponding to the part of the bandwidth after the handover.

Step 201: The user equipment uses a contention window (CW) for channel access.

Step 202: The user equipment sends data on a bandwidth unit in a carrier.

The contention window corresponds to the bandwidth unit.

In this way, by using the CW corresponding to the bandwidth unit in the carrier for channel access and sending data on the bandwidth unit, it is possible to adjust the CW value according to the reception of the uplink data sent on the bandwidth unit. The channel state corresponding to the bandwidth unit is adapted.

In this embodiment, the bandwidth unit (BW unit) may be various types of bandwidth units. For example, the bandwidth unit may be a partial bandwidth (BWP) or a sub-band (sub-band), or may be another type. The bandwidth unit is not limited in this embodiment of the present invention.

For example, the bandwidth unit is an uplink partial bandwidth (UL BWP), an LBT sub-band, or an LBT channel.

In this embodiment, one carrier may include two or more bandwidth units, where at least two of the bandwidth units in one carrier have different frequency domain starting positions and / or bandwidths. That is to say, there are at least two bandwidth units with different starting positions in the frequency domain among these bandwidth units, or there are at least two bandwidth units with different starting frequencies, or at least two frequency domains have different starting positions and different bandwidths.

For example, the network device notifies the UE of the uplink through a system message or RRC (Radio Resource Control) signaling. The configuration of one or more bandwidth units of the carrier (for example, the frequency domain start position / bandwidth, etc.). In addition, the active bandwidth unit may be indicated. When the UE receives the scheduling information, it determines the resources for sending uplink data according to the configuration of the activated bandwidth unit, and sends the uplink data on the activated bandwidth unit.

The following describes the division of the bandwidth unit (BW unit) in the carrier in this embodiment by way of example.

For example, as shown in FIG. 3, the bandwidth of BW unit 1 and BW unit 2 may be 20 MHz. However, it can also be 10MHz, 40MHz, or other values. Alternatively, the bandwidth of the bandwidth unit can be expressed as the number of PRB (Physical Resource Block) using a certain subcarrier interval. For example, a BW unit includes 106 PRBs, and the subcarrier interval is 15KHz. Among them, one PRB includes 12 subcarriers, corresponding to 180kHz.

In addition, the BW unit in FIG. 3 may be a UL BWP or an LBT sub-band or an LBT channel, or another type of bandwidth unit.

Among them, BW unit 1 and BW unit 2 have different starting positions in the frequency domain and have the same bandwidth. BW unit 3 and BW unit 1 The bandwidth of BW unit is different.

For example, as shown in Figure 4, the bandwidth of BW unit 1 and BW unit 2 can be 20 MHz, but it can also be 10 MHz, 40 MHz, or other values. The bandwidth of BW unit 3 can be 40 MHz, but it can also be 20 MHz and 80 MHz. , Or other values. Alternatively, the bandwidth of the bandwidth unit may be expressed as the number of PRB (Physical Resource Block) using a certain subcarrier interval. For example, a BW unit includes 106 PRBs, and the subcarrier interval is 15KHz. Among them, one PRB includes 12 subcarriers, corresponding to 180kHz.

In addition, the BW unit in FIG. 4 may be a UL BWP or LBT sub-band, or another type of bandwidth unit.

FIG. 5 is another schematic diagram of a bandwidth unit according to Embodiment 1 of the present invention. As shown in FIG. 5, BW unit 1 to BW unit 7 are included in one carrier. Among them, BW unit 1, BW unit 2, BW unit 3, and BW unit 4 have different starting positions in the frequency domain and have the same bandwidth. BW unit 5 The starting position in the frequency domain is different from that of BW unit 6, and the bandwidth is the same. The bandwidth of BW unit 7 and other BW units are different.

For example, as shown in Figure 5, the bandwidth of BW unit 1, BW unit 2, BW unit 3, and BW unit 4 can be 20MHz, but it can also be 10MHz, 40MHz, or other values. BW unit 5 and BW unit 6 The bandwidth can be 40MHz, but it can also be 20MHz, 80MHz, or other values. The bandwidth of BW unit 7 can be 80MHz, but it can also be 40MHz, 1600MHz, or other values. Alternatively, the bandwidth of the bandwidth unit may be expressed as the number of PRB (Physical Resource Block) using a certain subcarrier interval. For example, a BW unit includes 106 PRBs, and the subcarrier interval is 15KHz. Among them, one PRB includes 12 subcarriers, corresponding to 180kHz.

In addition, the BW unit in FIG. 5 may be a UL BWP or LBT sub-band, or another type of bandwidth unit.

In this embodiment, the contention window corresponding to the bandwidth is one of a contention window set. The one contention window set includes at least one contention window, and different contention windows correspond to different channel access priorities.

In this embodiment, one bandwidth unit or one carrier may be configured with one contention window set. In this embodiment, for a bandwidth unit configured with a contention window set, the contention window corresponds to the bandwidth unit, which means that the contention window is one of the contention window sets configured by the bandwidth unit;

For a carrier configured with a contention window set, the contention window corresponds to the bandwidth unit, which means that the contention window is one of the contention window sets of the carrier configuration, and the value of the contention window is at least according to the bandwidth unit OK for activation.

For example, for a bandwidth unit in a carrier, a contention window set is configured, and the contention window set includes at least one contention window corresponding to a channel access priority. When there are multiple contention windows, different contention windows Corresponds to different channel access priorities.

In this embodiment, a contention window may correspond to a contention window value (CWV) set. For example, for CW1, its CWV set can be {3,7}.

In this embodiment, the contention window is related to the priority, and the channel access priority and corresponding contention window used for channel access can be determined according to the data to be sent.

The structure of a contention window set is exemplarily described below.

FIG. 6 is a schematic diagram of a contention window in Embodiment 1 of the present invention. As shown in FIG. 6, the contention windows CW1, CW2, CW3, and CW4 correspond to channel

access priorities

1, 2, 3, and 4, respectively. The contention window value set of contention window CW1 is {3,7}, and contention of CW2 The window value set is {7,15}, the CW3 competition window value set is {15,31,63,127,255,511,1023}, and the CW4 competition window value set is {15,31,63,127,255,511,1023}. The number in each set indicates how many time intervals, and each time interval is, for example, 9 microseconds. For example, "7" in the set {7,15} indicates that the value of the contention window is 7 time intervals.

In this embodiment, as shown in FIG. 2, before step 201, the method may further include:

Step 203: The user equipment determines a value of the contention window.

That is, the user equipment determines a value of a contention window corresponding to the bandwidth unit.

In this embodiment, “determining” may also be referred to as “set” or “setting”. In addition, when the value of the competition window before and after the determination changes, it may also be referred to as “adjusting (adjusting) adjust) ".

In this embodiment, the value of the contention window belongs to the contention value set of the contention window. That is, the user equipment determines a value from a contention window value set belonging to the contention window as the value of the contention window corresponding to the bandwidth unit.

For example, for CW2 in FIG. 6, the user equipment determines a value from the contention window value set {7,15} belonging to CW2 as the value of CW2.

In this embodiment, for a bandwidth unit in a carrier, the bandwidth unit may be activated or the bandwidth unit may be deactivated.

In this embodiment, an example in which only one bandwidth unit in a carrier is in an active state is used for description. However, in one carrier, two or more bandwidth units may be activated.

The following is an exemplary description of switching between bandwidth units in a carrier.

FIG. 7 is a schematic diagram of bandwidth unit switching according to Embodiment 1 of the present invention. As shown in FIG. 7, the uplink carrier includes two bandwidth units, such as UL BWP1 and UL BWP2. The contention window corresponding to UL BWP1 is CW1, and the contention window corresponding to UL BWP2 is CW2. When switching from UL BWP1 to UL BWP2, that is, when UL BWP1 is deactivated and UL BWP2 is activated, the contention window used for channel access is also changed from CW1 to CW2. When switching from UL BWP2 to UL, BWP2 When UL BWP2 is deactivated and UL BWP1 is activated, the contention window used in channel access is also changed from CW2 to CW1.

In this embodiment, for a bandwidth unit configured with a contention window set, in step 203, the user equipment may determine the value of the contention window according to at least one of the following: activation and / or deactivation of the bandwidth unit; The state of the timer corresponding to the bandwidth unit; the first configuration information received; and the second configuration information received.

In this embodiment, the first configuration information may include at least one of: an initial value of a contention window corresponding to the bandwidth unit, a set of contention windows corresponding to the bandwidth unit, and a channel access priority corresponding to the bandwidth unit, that is, What are the channel access priorities corresponding to this bandwidth unit. For example, for a bandwidth unit, in the first configuration information, the initial value of the CW corresponding to the bandwidth unit is set to 7, and the channel access priorities corresponding to the bandwidth unit are 1 and 3.

In this embodiment, for a bandwidth unit configured with a contention window set, the first configuration information and the configuration information of the bandwidth unit may be sent in the same RRC Information Element (RRC Information Element).

In addition, the first configuration information may not be sent by the network device. In this case, the foregoing information included in the first configuration information may be predefined or pre-configured. For example, at least one of an initial value of a contention window corresponding to the bandwidth unit, a set of contention windows corresponding to the bandwidth unit, and a channel access priority corresponding to the bandwidth unit is predefined or pre-configured.

According to the first configuration information, an initial value of a contention window corresponding to a bandwidth unit may be determined. In addition, the user equipment may also autonomously determine the initial value of the contention window corresponding to a bandwidth unit, for example, randomly select a value from the contention value set of the contention window as the initial value.

In this embodiment, the first configuration information is sent by a network device, for example, is sent through at least one of system information, RRC signaling, and MAC signaling.

In this embodiment, the second configuration information may include at least one of: a value of the contention window or an index of a value of the contention window, and information of a bandwidth unit, for example, an index of a bandwidth unit, such as BWP index.

In this embodiment, the second configuration information is sent by a network device. For example, the second configuration information is sent through at least one of a MAC (Media Access Control) signaling and a Physical Downlink Control Channel (PDCCH). For example, the second configuration information is sent through the PDCCH, and the DCI carried by the PDCCH includes the second configuration information.

In this embodiment, the index of the contention value of the competition window refers to, for example, the sequence number of each value in the contention value set of the contention window of the contention window.

In this embodiment, the timer is configured by a network device. For example, the timer is configured for one bandwidth unit in a carrier, or the timer is configured for at least two bandwidth units in a carrier. .

When the timer configures a bandwidth unit in a carrier, the third configuration information used to configure the timer may be sent in the same RRC information element (RRC Information Element) as the configuration information of the bandwidth unit.

The following specifically describes the specific method of determining the value of the contention window in this embodiment. The user equipment determines the value of the contention window according to which factors, and which of the multiple rules is specifically used for determination, which may be predefined, for example, specified in the standard, or may be pre-configured by the network device.

In one example, the user equipment determines the value of the contention window according to the activation and / or deactivation of the bandwidth unit.

For example, when a bandwidth unit is deactivated, the value of the contention window corresponding to the bandwidth unit is reset, or the value of the contention window corresponding to the bandwidth unit is kept unchanged, or according to the value sent before the bandwidth unit is activated. The data receiving situation determines the value of the contention window corresponding to the bandwidth unit.

In this embodiment, resetting the value of the contention window corresponding to the bandwidth unit may be one of the following: resetting the value of the contention window corresponding to the bandwidth unit to the contention window value set of the contention window This method can enable the user equipment to access the channel as soon as possible, or reset the value of the contention window corresponding to the bandwidth unit to the maximum value in the contention window value set of the contention window. This method can The influence on other devices using the same channel is minimized as much as possible. In addition, the value of the contention window corresponding to the bandwidth unit may be reset to a random value in the contention window value set of the contention window. For example, the contention window corresponding to the bandwidth unit is CW3 in FIG. 6, and the value set of the contention window of CW3 is {15,31,63,127,255,511,1023}. When the value of CW3 is reset, the value can be reset. The minimum value is 15, which can also be reset to a maximum value of 1023, or it can be reset to a random value in the set, such as 255.

For another example, when a bandwidth unit is activated, the value of the contention window corresponding to the bandwidth unit is reset, or the value of the contention window corresponding to the bandwidth unit before the bandwidth unit is activated is used.

In another example, the user equipment determines the value of the contention window according to the activation and / or deactivation of the bandwidth unit and the state of a timer corresponding to the bandwidth unit.

For example, when a bandwidth unit is deactivated, the value of the contention window corresponding to the bandwidth unit does not change, or the value of the contention window corresponding to the bandwidth unit is adjusted according to the reception of data sent by the bandwidth unit.

For another example, when a bandwidth unit is activated, if the timer is not running (expire) or timeout (expire), the value of the contention window corresponding to the bandwidth unit is reset, and the timer runs (running) In the case of no timeout (expire), the value of the corresponding competition window before the activation of the bandwidth unit is adopted.

In this embodiment, the start or restart conditions of the timer corresponding to the bandwidth unit may include at least one of the following (that is, when at least one of the following conditions is met, the timer is started or restarted): when the corresponding bandwidth unit is deactivated (For example, according to the instruction of the network device or the bandwidth unit corresponding to the BWP-InactivityTimer); when the corresponding bandwidth unit sends data; when the associated information of the data sent by the corresponding bandwidth unit is received.

The data related information is, for example, HARQ process and new data indicator (NDI) in the downlink control information (DCI) including uplink grant (UL grant) or HARQ-ACK information in DCI.

In this embodiment, the stop condition of the timer corresponding to the bandwidth unit may include at least one of the following:

After the corresponding bandwidth unit is activated and the value of the contention window is determined;

The base station was instructed to stop the timer.

In another example, the user equipment determines the value of the contention window according to the received second configuration information.

For example, the second configuration information includes a value of the contention window or an index of the value of the contention window. In this case, the value of the contention window corresponding to the currently activated bandwidth unit may be determined as the value of the contention window indicated by the second configuration information or the value of the contention window indicated by the index, or the configured bandwidth The value of the contention window corresponding to the unit is determined to be the value of the second configuration information indicating the contention window or the value of the contention window indicated by the index.

For another example, the second configuration information includes a value of the contention window or an index of the contention window value, and information of a bandwidth unit. In this case, the contention window corresponding to the bandwidth unit indicated by the second configuration information may be determined as the value of the contention window indicated by the second configuration information or the value of the contention window indicated by the index.

In another example, the user equipment determines the value of the contention window according to the activation and / or deactivation of the bandwidth unit and the received second configuration information.

For example, when the bandwidth unit is activated and / or deactivated according to a timer, the value of the contention window is determined according to the activation and / or deactivation of the bandwidth unit. The specific method can be the same as the above description, and will not be repeated here.

When the bandwidth unit is activated and / or deactivated according to the instruction of the network device, the value of the contention window is determined according to the second configuration information. The specific method may be the same as the above description, and will not be repeated here.

In another example, the user equipment determines the value of the contention window corresponding to the bandwidth unit according to the status of the timer corresponding to the activation and / or deactivation of the bandwidth unit and the bandwidth unit and the received second configuration information. .

As another example, when the bandwidth unit is activated and the second configuration information is not received before the activation, if the timer times out, the value of the contention window corresponding to the bandwidth unit is reset, and the timer does not time out. In the case of the same, the value of the contention window corresponding to the bandwidth unit is kept unchanged.

As another example, when the bandwidth unit is activated and the second configuration information is received before the activation, the value of the contention window of the bandwidth unit is set according to the second configuration information.

In this embodiment, for a carrier configured with a contention window set, in step 203, the user equipment may determine the value of the contention window according to at least one of the following: activation and / or deactivation of the bandwidth unit; reception First configuration information; and received second configuration information.

For this case, the specific method for determining the value of the contention window can refer to the above example, and the description will not be repeated here.

Step 801: Generate an initial value of the first counter according to the value of the contention window.

Step 802: Determine the idle state of the channel corresponding to the bandwidth unit by detecting the energy and / or signal on the bandwidth unit, and operate the first counter according to the idle state of the channel corresponding to the bandwidth unit.

In this embodiment, the first counter is, for example, a random back-off talk-before-talk (LBT) counter.

In step 801, for example, the value of the contention window is CWV. Then, the initial value of the LBT counter may be a randomly determined integer between 0 and CWV.

In step 802, an idle state of a channel corresponding to the bandwidth unit in each time interval of the CWV is determined by detecting energy and / or signals on the bandwidth unit. When the channel is idle, the LBT counter is decremented. 1. When the channel is not idle, the LBT counter is not operated.

When the value of the LBT counter is 0, step 202 may be performed, that is, uplink data may be sent on the bandwidth unit.

It can be known from the foregoing embodiments that channel access is performed by using a CW corresponding to a bandwidth unit in a carrier and data is transmitted on the bandwidth unit, so that the CW can be valued according to the reception status of uplink data sent on the bandwidth unit The adjustment can be adapted to the channel state corresponding to the bandwidth unit.
