Technical field

The present disclosure relates to the field of communications technologies, and in particular, to a method for configuring a transmission interval, a device for configuring a transmission interval, and a user equipment.

Background technique

A mobile communication system refers to a system in which an operator provides communication services for user equipment (such as a mobile phone) by deploying a wireless access network device (such as a base station) and a core network device (such as a Home Location Register (HLR)). . Mobile communication systems have experienced first, second, third and fourth generations. The first generation mobile communication system refers to the original analog, voice-only cellular phone standard, mainly using analog technology and Frequency Division Multiple Access (FDMA) access method; second generation mobile communication The system introduces digital technology, improves network capacity, and improves voice quality and confidentiality. It is called "Global System for Mobile Communication" (GSM) and "Code Division Multiple Access" (referred to as Code Division Multiple Access). CDMA (IS-95) is the representative; the third generation mobile communication system mainly refers to CDMA2000, Wideband Code Division Multiple Access (WCDMA) and Time Division-Synchronous Code Division. Multiple Access (TD-SCDMA) three technologies are based on code division multiple access as the access technology; the standards of the fourth generation mobile communication system are relatively unified internationally, and are the International Organization for Standardization - Third Generation Partnership Project Long Term Evolution/Long Term Evolu (3rd Generation Partnership Project, 3GPP) tion-Advanced, referred to as LTE/LTE-A), whose downlink is based on Orthogonal Frequency Division Multiple Access (OFDMA), and uplink based on Single Carrier-Frequency Division (Single Carrier-Frequency Division) Multiple access, referred to as SC-FDMA) access mode, and based on flexible bands The wide and adaptive modulation and coding method achieves high-speed transmission with a downlink peak rate of 1 Gbps and an uplink peak rate of 500 Mbps.

Based on the LTE R13 Authorized Access (LAA) downlink transmission method, the MulteFire (MF) standard defines the uplink transmission method and can work independently in the unlicensed frequency band through technical enhancement.

Generally, an Evolved Node B (eNB) transmission opportunity (TxOP) may be as shown in FIG. 1 , where the short physical uplink control channel (sPUCCH) is occupied. The last four symbols of the uplink and downlink handover subframes, where the uplink and downlink handover subframes can pass the common physical downlink control channel (C-PDCCH) on the current subframe and/or the previous subframe To give instructions. In addition, the MF supports two physical random access channels (PRACH) forms, that is, PRACH (referred to as MF-sPRACH) and MF-ePUCCH (MF-Extended Physical Uplink Control Channel) in the MF-sPUCCH. PRACH (referred to as MF-ePRACH).

With reference to the provisions of the European Telecommunications Standards Institute (ETSI), the case where the MF allows the uplink transmission without the Listening Before Talk (LBT) is "UL transmission starts without LBT within 16μs after the DL transmission ends". LBT is not required when the time interval of uplink transmission is less than 16μs."

At the same time, the time interval is also required between the TxOPs. The time interval for the uplink transmission of the end portion of the eNB TxOP and the uplink transmission of the user equipment UE TxOP is used for LBT, and the downlink transmission for the end portion of the eNB TxOP starts with the next eNB TxOP. The time interval of part of the downlink transmission is used for the LBT, and the time interval for the uplink transmission of the end portion of the eNB TxOP and the downlink transmission of the beginning portion of the next eNB TxOP is used for the uplink and downlink conversion and the LBT.

For a UE different from the eNB, the channel round-trip delay corresponding to the maximum timing advance (TA), and the downlink arrival time and uplink transmission time for the UE far from the eNB (Cell-edge) More recently, when it is less than or equal to 16μs (see FIG. 2), if the uplink data is directly sent without LBT, the time interval Gap of the downlink transmission and the uplink transmission (for example, 1symbol=71μs) is greater than the timing of the eNB. 16μs, so there may be other devices (such as UEs of other networks close to the eNB). The LBT is successful in the Gap. Interference.

If the eNB sets the Gap to be less than 16 μs, the time interval between the downlink reception and the uplink transmission of the at least the Cell-edge UE (the larger TA) may be less than 16 μs or even overlap, resulting in the failure to transmit the first uplink transmission after the downlink reception. Uplink signal.

That is, the current UE is often interfered by other UEs due to the problem of the time interval between the downlink reception and the uplink transmission, which affects channel competition.

Summary of the invention

The specific embodiments of the present disclosure are further described below in conjunction with the accompanying drawings and embodiments. The following examples are only intended to illustrate the disclosure, but are not intended to limit the scope of the disclosure.

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. It is apparent that the described embodiments are a part of the embodiments of the present disclosure, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without departing from the inventive scope are the scope of the disclosure.

Referring to FIG. 3, an embodiment of the present disclosure provides a method for configuring a transmission interval, which is applied to a user equipment. The method includes steps 301-302.

Step 301: Acquire transmission interval information of downlink transmission and uplink transmission in an evolved Node B (eNB) transmission opportunity (TxOP).

In the embodiment of the present disclosure, the transmission interval information includes at least the number of symbols of the downlink end subframe and the preset timing advance of the uplink transmission of the user equipment UE in the eNB TxOP, or at least the number of symbols of the downlink end subframe. a preset time interval between the downlink transmission and the uplink transmission in the eNB TxOP.

The number of symbols of the downlink end subframe may be indicated by a common physical downlink control channel (C-PDCCH) on the downlink end subframe or a previous subframe of the downlink end subframe. It should be noted that the number of symbols in the complete subframe is 14, and the sPUCCH often occupies the last four symbols of the uplink and downlink handover subframes. Therefore, the downlink transmission in the corresponding eNB TxOP can be obtained by using the number of symbols of the downlink end subframe. The number of interval symbols (symbol level) with the upstream transmission. And a symbol often corresponds to 71μs, Then, the time interval (microsecond (μs) level) of the downlink transmission and the uplink transmission of the corresponding eNB TxOP can be obtained by combining the cell-specific TA.

The preset timing advance of the uplink transmission of the UE in the eNB TxOP may be notified in system information, for example, (System Information Block-MF, SIB-MF), or may be pre-defined in the standard, which is not limited by the disclosure.

The preset time interval of the downlink transmission and the uplink transmission in the eNB TxOP may be notified in system information such as SIB-MF, or may be predetermined in the standard. Moreover, the preset time interval may be directly indicated by a message, or may be jointly indicated by multiple messages, for example, by a joint symbol number and a cell common timing advance amount, which is not limited by the disclosure.

Step 302: Determine, according to the transmission interval information and the UE timing advancement quantity, a target time interval of downlink transmission and uplink transmission of the UE in the eNB TxOP.

In this way, the UE performs uplink transmission on the premise that the target time interval is met, and the matching with the corresponding eNB TxOP can be implemented to meet the system requirements.

The method for configuring the transmission interval in the embodiment of the present disclosure can flexibly support different time interval sizes, and improve the channel success rate of the device while reducing the interference probability between the devices.

Referring to FIG. 4, an embodiment of the present disclosure provides another method for configuring a transmission interval, which is applied to a user equipment. The method includes steps 401 - 403.

Step 401: Acquire the number of symbols of the downlink end subframe in the eNB TxOP and the preset timing advance of the uplink transmission of the UE in the eNB TxOP.

In the embodiment of the present disclosure, the number of symbols of the downlink end subframe and the preset timing advance amount are transmission interval information of the downlink transmission and the uplink transmission in the corresponding eNB TxOP. The preset timing advance may be used to enable the UE to dynamically, periodically, or periodically adjust the uplink transmission transmission time. The preset timing advance may be notified in the system information (generally corresponding to dynamic or periodic adjustment of the uplink transmission transmission time), or may be pre-defined in the standard (generally corresponding to the fixed adjustment uplink transmission transmission time).

Step 402: Determine, according to the number of symbols of the downlink end subframe and the timing advance of the UE, the initial transmission time of the uplink transmission of the UE in the eNB TxOP.

In the embodiment of the present disclosure, the number of symbols of the downlink transmission and the uplink transmission in the eNB TxOP corresponding to the downlink end subframe may be obtained by using the number of symbols of the downlink end subframe. According to the number of the interval symbols and the timing advance of the UE, the UE may determine the uplink transmission in the eNB TxOP. The initial transmission time is lost.

The downlink end subframe may be a partial subframe (downlink pilot time slot (DwPTS)), and the symbol length is [3, 6, 9, 10, 11, 12]; The downlink end subframe may also be a complete subframe, and the symbol length is 14.

Step 403: Perform an advance or deferred adjustment on the uplink transmission initial transmission time according to the preset timing advance quantity, and determine a target time interval of the downlink transmission and the uplink transmission of the UE in the eNB TxOP to adjust the eNB. The time interval between the downlink transmission and the uplink transmission in the TxOP.

Specifically, the uplink transmission initial transmission time is adjusted in advance or deferred according to the preset timing advance amount, mainly by advancing the uplink transmission initial transmission time or delaying the uplink transmission initial according to the preset timing advance amount. The time is transmitted to adjust the time interval between the downlink transmission and the uplink transmission in the corresponding eNB TxOP.

In the embodiment of the present disclosure, the transmission interval information of the downlink transmission and the uplink transmission in the eNB TxOP acquired by the UE may further include an indication of a Listening Before Talk (LBT) that does not need to perform uplink transmission, or needs to perform uplink transmission. The instructions for the LBT.

When the transmission interval information includes an indication of an LBT that does not need to perform uplink transmission, the method of the embodiment of the present disclosure further includes: controlling the UE to skip the LBT and directly perform uplink transmission.

When the transmission interval information includes an indication of an LBT that needs to perform uplink transmission, the method of the embodiment of the present disclosure further includes: comparing downlink transmission and uplink transmission in the eNB TxOP (here, the first one can perform uplink transmission) The relationship between the time interval of the resource and the first preset threshold and the second preset threshold, the second preset threshold is greater than the first preset threshold; and the downlink transmission in the eNB TxOP When the time interval of the uplink transmission is greater than or equal to the first preset threshold, the UE is controlled to perform LBT before the uplink transmission; or the time interval between the downlink transmission and the uplink transmission in the eNB TxOP is less than or equal to the When the second preset threshold is used, the UE is controlled not to perform the LBT; or when the time interval between the downlink transmission and the uplink transmission in the eNB TxOP is greater than the second preset threshold and less than the first preset threshold, Controlling the UE to send a reservation signal to the eNB and skipping the LBT to directly perform uplink transmission, where the reserved signal is used to make the difference between the target time interval and the duration of the reserved signal is smaller than the first Preset threshold.

For example, the time interval between the downlink transmission and the uplink transmission in the eNB TxOP is T _gap , and the first preset threshold is (25+T _rx−tx +TA _max ) μs, where TA _max is the maximum TA of the UE in the current eNB. The value, T _rx-tx is the conversion delay (maximum or typical value) of the UE receiving the uplink transmission from the downlink, and when the T _{gap is} greater than or equal to (25+T _rx-tx +TA _max ) μs, the eNB is under the eNB. The uplink transmission of all UEs needs to perform LBT; the second preset threshold is 16 μs, and when T _{gap is} less than or equal to 16 μs, LBT is not required for UEs with (T _gap -TA-T _rx-tx ) greater than 0, for (16- The UE whose TA-T _rx-tx ) is less than 0 is not transmitted by the first uplink transmission opportunity, that is, the eNB does not schedule the UE. When T _{gap is} larger than 16μs and smaller than (25+T _rx-tx +TA _max )μs, UEs with T _rx-tx <(T _gap -TA)<16μs do not need LBT to transmit directly, for (T _gap -TA)> The 16 μs UE makes T _rx-tx <(T _gap -TA-Tr)<16 μs by transmitting the reserved signal of the Tr duration in advance.

The method for configuring the transmission interval in the embodiment of the present disclosure can adjust the time interval of the downlink transmission and the uplink transmission in the corresponding eNB TxOP dynamically, periodically, or fixedly by using the preset timing advance, and further pass the LBT that needs to perform uplink transmission. The uplink LBT mode is selected to improve the channel success rate of the device and reduce the interference probability between the devices.

Referring to FIG. 5, an embodiment of the present disclosure provides a method for configuring a transmission interval, which is applied to a user equipment. The method includes steps 501 - 503.

Step 501: Acquire the number of symbols of the downlink end subframe in the eNB TxOP and the preset time interval of the downlink transmission and the uplink transmission in the eNB TxOP.

In the embodiment of the present disclosure, the number of symbols and the preset time interval of the downlink end subframe are the transmission interval information of the downlink transmission and the uplink transmission in the corresponding eNB TxOP. The preset time interval is a fixed time interval between the downlink transmission and the uplink transmission in the eNB TxOP, and may be notified in the system information, or may be predetermined in the standard.

Step 502: Determine, according to the number of symbols of the downlink end subframe and the timing advance of the UE, the initial transmission time of the uplink transmission of the UE in the eNB TxOP.

In the embodiment of the present disclosure, the number of symbols of the downlink transmission in the eNB TxOP corresponding to the downlink end subframe and the number of interval symbols in the uplink transmission that is not adjusted by the transmission time may be obtained by using the number of symbols of the downlink end subframe. And according to the number of the interval symbols and the timing advance of the UE itself, the UE may determine an initial transmission time of the uplink transmission in the eNB TxOP.

Step 503: Determine a target time interval of the downlink transmission and the uplink transmission of the UE in the eNB TxOP by using an advance or deferred adjustment of the initial transmission time of the uplink transmission, so that the downlink transmission and the uplink transmission in the eNB TxOP are performed. The time interval is the preset time interval.

Specifically, the early or delayed adjustment of the initial transmission time of the uplink transmission is mainly advanced. The uplink transmission initial transmission time or the uplink transmission initial transmission time is delayed, so that the time interval between the downlink transmission and the uplink transmission in the eNB TxOP is the preset time interval.

For example, the preset time interval indicated in the system message is a value less than 1 symbol (71 μs) Xμs (X<71), and when the downlink end subframe is a partial subframe (ie, DwPTS), the symbol length is [3] 6, 9, 9, 10, 11, 12], the uplink transmission time of the UE is automatically adjusted to maintain the position of the Xμs interval, wherein when the length of the DwPTS is [3, 6, 9], the UE may send the sPUCCH and adjust the corresponding transmission. The time size is used to ensure the interval size. When the length of the DwPTS is [10, 11, 12], the UE may send the physical uplink shared channel PUSCH and adjust the corresponding transmission time size to ensure the interval size (which may be based on the first symbol of the PUSCH by default). Start position to adjust or adjust according to the actual transmission position of PUSCH). When the downlink end subframe is a complete subframe, that is, when the symbol length is 14, the first symbol start position of the PUSCH may be adjusted by default or adjusted according to the actual transmission position of the PUSCH.

The selection of the LBT mode may be performed in the same manner as the embodiment shown in FIG. 4 above, and the details are not described herein again.

In the embodiment of the present disclosure, after adjusting the initial transmission time of the uplink transmission, if the next subframe of the eNB TxOP is another eNB TxOP, the method further includes: determining an adjustment amount of the initial transmission time of the uplink transmission. The time interval between the eNB TxOP and the another eNB TxOP.

In this way, the other eNB TxOP can be allowed to have sufficient time intervals for LBT.

In the embodiment of the present disclosure, the transmission interval information of the downlink transmission and the uplink transmission in the eNB TxOP acquired by the UE may further include a cell-specific TA. The cell-specific TA can be either notified in the system message or pre-specified in the standard.

When the next subframe of the eNB TxOP is the UE TxOP, the uplink transmission transmission time of the UE in the UE TxOP may refer only to the value of the cell-specific TA, that is, the eNB TxOP and the eNB are determined according to the cell-specific TA. The time interval of the UE TxOP. And when the uplink transmission transmission time in the eNB TxOP is advanced, the UE also has enough time to perform the Cat-4 LBT.

Further, the cell-specific TA includes a cell-specific TA for uplink transmissions other than the UE TxOP and a cell-specific TA for uplink transmission within the UE TxOP.

For example, for a UE TxOP that the UE successfully competes through the cat-4 LBT, its Cell-specific TA (ie, the cell-specific TA of the uplink transmission in the UE TxOP) can be set to 0, and the non-zero cell-specific TA is used for the uplink transmission other than the UE TxOP. This configuration can allow sufficient time for the UE TxOP after the eNB TxOP. Intermit the cat-4 LBT.

The method for configuring the transmission interval in the embodiment of the present disclosure can adjust the time interval of the downlink transmission and the uplink transmission in the corresponding eNB TxOP by using the preset time interval, and flexibly support different target time interval sizes, and improve the success rate of the UE channel competition. , reducing the probability of interference between UEs.
