Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and specifically to a data transmission method, apparatus, user terminal, and computer-readable storage medium. Background Technology

[0002] In existing Long Term Evolution (LTE) systems, base stations use a fixed-length Transmission Time Interval (TTI) to send Downlink Control Information (DCI) to User Equipment (UE) for scheduling downlink and uplink data. The TTI is 1ms in length.

[0003] For a 1ms TTI, a connected UE needs to detect 12 DCIs in the common search area of ​​the Physical Downlink Control Channel (PDCCH) region and 32 DCIs in the UE-specific search area of ​​the PDCCH region, for a total of 44 blind detections.

[0004] To reduce latency, a shorter TTI (Time Interval) is introduced in the LTE system. To distinguish it from the 1ms TTI, sTTI is used to represent the shorter TTI, sDCI is used to represent DCI transmitted via sTTI, and sPDCCH is used to represent PDCCH that transmits sDCI.

[0005] With the introduction of sTTI, taking a 2-symbol sTTI as an example, there will be 6 sTTIs within a subframe for the extended cyclic prefix (CP). Within 1ms, the UE needs to blindly detect the common search area in the PDCCH region and the DCI within the UE-specific search area in the sPDCCH region within each sTTI. The total number of blind detections will far exceed 44, consuming a lot of UE power and increasing the UE's processing complexity.

[0006] In light of the above situation, how to reduce the processing complexity and power consumption of the UE when detecting downlink control signaling has become an urgent technical problem to be solved. Summary of the Invention

[0016] Optionally, it further includes: when the downlink control signaling is not detected within a preset time period, suspending the detection of the downlink control signaling, and retaining the detection period of the downlink control signaling and the location indication information.

[0017] Optionally, after detecting the suspended downlink control signaling, the method further includes: upon receiving an indication from the base station to resume downlink control signaling, detecting downlink control signaling according to the detection period of the downlink control signaling and the location indication information.

[0018] This invention also provides another data transmission method, the method comprising: sending a detection period for detecting downlink control signaling to a UE, and detecting location indication information for downlink control signaling within the detection period, wherein the UE performs downlink control signaling detection based on the detection period for downlink control signaling and the location indication information.

[0023] Optionally, the location indication information includes: identification information of the subframe or time slot in which downlink control signaling is detected within the detection period.

[0024] Optionally, the downlink control signaling is downlink control signaling transmitted within a transmission time interval of less than 1 ms.

[0026] Optionally, an instruction to resume downlink control signaling is sent to the UE, so that the UE resumes the detection of downlink control signaling according to the detection period of the downlink control signaling and the location indication information.

[0027] This invention also provides a data transmission apparatus, comprising: a receiving unit adapted to receive a detection period of downlink control signaling and to detect location indication information of downlink control signaling within the detection period; a detection unit adapted to detect downlink control signaling based on the detection period of downlink control signaling and the location indication information; and a data transmission unit adapted to transmit data according to the detected downlink control signaling.

[0030] Compared with the prior art, the technical solution of the embodiments of the present invention has the following advantages:

[0031] By adopting the above scheme, since the sTTI configuration information sent by the base station includes the application sTTI time interval information, the terminal can detect downlink control signaling based on the sTTI time interval information without having to continuously detect downlink control signaling. This reduces the processing complexity and power consumption of the UE when detecting downlink control signaling. Attached Figure Description

[0032] Figure 1 This is a flowchart of a data transmission method according to an embodiment of the present invention;

[0033] Figure 2 This is a schematic diagram of the structure of a data transmission device according to an embodiment of the present invention;

[0034] Figure 3 This is a schematic diagram of another data transmission device in an embodiment of the present invention. Detailed Implementation

[0035] In an LTE system, a radio frame consists of 10 subframes, each 10 ms long. Each subframe is 1 ms long. Each subframe contains two time slots, each 0.5 ms long. For a regular CP, each time slot contains 7 Orthogonal Frequency Division Multiplexing (OFDM) symbols. For an extended CP, each time slot contains 6 OFDM symbols.

[0036] For a TTI of 1ms, a UE in connected state needs to detect 12 DCIs in the common search area of ​​the PDCCH region and 32 DCIs in the UE-specific search area of ​​the PDCCH region, for a total of 44 blind detections.

[0037] To reduce latency, LTE systems introduce shorter sTTIs. With sTTIs, taking a 2-symbol sTTI as an example, there will be 6 sTTIs within a subframe for the Extended Cyclic Prefix (CP). The UE needs to perform blind detections within each sTTI on the common search area in the PDCCH region and the DCI within the UE-specific search area in the sPDCCH region. The total number of blind detections within 1 ms will far exceed 44, consuming significant power and increasing the UE's processing complexity.

[0038] To address the aforementioned issues, this invention provides a data transmission method. By setting the application time interval information of sTTI in the sTTI configuration information sent by the base station, the terminal can detect downlink control signaling based on the sTTI time interval information without continuously detecting downlink control signaling. This avoids a significant increase in processing complexity and power consumption for the UE when applying sTTI.

[0039] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] Reference Figure 1 This invention provides a data transmission method, which may specifically include the following steps:

[0041] Step 11: Receive sTTI configuration information sent by the base station. The sTTI configuration information includes: sTTI length information and time interval information for applying the sTTI, wherein the length of the sTTI is less than 1ms.

[0042] In practice, there is no limit to the specific length of sTTI. For example, the length of sTTI can be 2 OFDM symbols or 7 OFDM symbols.

[0043] In practice, after the UE accesses the serving cell and establishes an RRC connection, the UE reports its capability information to the base station. For example, the UE can report that it supports sTTI scheduling and that the supported sTTI length is 2 symbols. After the base station receives the capability information reported by the UE and the UE establishes a service bearer with low latency requirements (for example, if the service quality parameters of a certain data radio bearer of the UE indicate low latency requirements), the base station can configure sTTI configuration information for the UE.

[0044] In specific implementations, the sTTI configuration information may include: the length information of the sTTI and the time interval information for applying the sTTI.

[0045] In one embodiment of the present invention, the length information of the sTTI can be the uplink sTTI length information, which is used to schedule the UE to perform uplink data transmission according to the uplink sTTI length information.

[0046] In another embodiment of the present invention, the length information of the sTTI can also be the downlink sTTI length information, which is used to schedule the UE to perform downlink data transmission according to the downlink sTTI length information, that is, to decode downlink control signaling on the OFDM symbol corresponding to the downlink sTTI length, and to receive downlink data according to the downlink control signaling.

[0047] In another embodiment of the present invention, the length information of the sTTI may also include uplink sTTI length information and downlink sTTI length information, that is, simultaneously configure the UE with the length information of the sTTI required for uplink data transmission and downlink data transmission, that is, decode downlink control signaling on the OFDM symbol corresponding to the downlink sTTI length, and transmit uplink data according to the downlink control signaling.

[0048] In practice, the uplink sTTI length and the downlink sTTI length can be the same or different, without any restrictions. For example, the uplink sTTI length can be 3 OFDM symbols, but the downlink sTTI length can be 2 ODM symbols.

[0049] In practice, various methods can be used to set the time interval information for applying the sTTI, and there are no specific restrictions.

[0050] In one embodiment of the present invention, the time interval information for applying the sTTI may include: the number of subframes or the number of sTTIs between two consecutive scheduling of the UE by the base station using the sTTI. The number of subframes or the number of sTTIs between two consecutive scheduling of the UE by the base station is not limited and can be set by those skilled in the art according to actual needs, such as setting the number of subframes or the number of sTTIs based on the processing capacity of the UE.

[0051] In another embodiment of the present invention, the time interval information for applying the sTTI may include: periodic information of the base station scheduling the UE with the sTTI, and location indication information of the UE scheduled with the sTTI within each period.

[0052] In specific implementation, the base station can configure the application sTTI period. For example, the base station schedules the UE with a period of 10ms, that is, the UE detects sDCI at the corresponding position every 10ms. The corresponding position can include one or more sTTI positions within the period, such as one or more sTTI positions starting from the beginning position of the period within the 10ms period. The UE only needs to detect downlink control signaling within one or more sTTI positions starting from the beginning position of the period.

[0053] In one embodiment of the present invention, the location indication information of the user terminal scheduled by the sTTI in each period may include: the identification information of the subframe or time slot of the user terminal scheduled by the sTTI in each period, that is, the terminal only needs to detect the downlink control signaling in the corresponding subframe or time slot of the subframe or time slot in the period.

[0054] Step 12: Based on the sTTI configuration information, detect downlink control signaling within the corresponding sTTI and transmit data according to the detected downlink control signaling.

[0055] For example, the base station can set the minimum interval between two consecutive sTTI scheduling of the UE to 4 subframes. After the base station uses sTTI to schedule the UE in subframe 1, it will only use sTTI to schedule the UE in the following subframe 5. In subframes 2, 3, and 4, it will use a TTI with a length of 1ms to schedule the UE or not schedule the UE at all.

[0056] For example, when the sTTI length is 2 OFDM symbols, there are 6 sTTIs in a subframe, numbered sTTI1 to sTTI6. The base station can set the minimum interval between two consecutive sTTI scheduling events to be 2 sTTIs. If the base station has already scheduled the UE via sDCI in the first sTTI, it will not schedule the UE in sTTI2 and sTTI3, but will schedule the UE again in sTTI4. In this case, the UE only needs to detect sDCI in sTTI4.

[0057] In one embodiment of the present invention, the UE may receive the time interval information for applying the sTTI solely from the Radio Resource Control (RRC) signaling sent by the base station.

[0058] In another embodiment of the invention, the UE may also receive time interval information for applying the sTTI from RRC signaling and from the DCI (i.e., sDCI) detected within the corresponding sTTI.

[0059] In practical implementation, since the number of bits that can be transmitted in the sDCI is limited, the base station can configure the index corresponding to the time interval for applying the sTTI in the sDCI, and configure different indexes corresponding to the time intervals for applying the sTTI in the RRC signaling. For example, the base station can configure the index for applying the sTTI for a time interval of 2 subframes as 0, and the index for applying the sTTI for a time interval of 3 subframes as 1 in the RRC signaling. At the same time, a bit can be used in the sDCI to indicate that the index corresponding to the next time interval for applying the sTTI is 0 (this bit is set to 0), or the same bit can be used to indicate that the index corresponding to the next time interval for applying the sTTI is 1 (this bit is set to 1). Based on the index number in the sDCI, the UE can look up the information in the RRC signaling to find the time interval for the next time the UE will be scheduled using the sTTI.

[0060] In specific implementation, when the time interval information of the sTTI includes periodic information of the base station scheduling the UE with the sTTI, and location indication information of the UE scheduled with the sTTI within each period, the UE can detect the downlink control signaling on the subframes or time slots identified in each period based on the sTTI configuration information. That is, the UE can detect sDCI on a determined number of subframes or time slots within each period.

[0061] Taking a 10ms sTTI period as an example, the base station can specify the first two subframes of each period as the subframes to be scheduled for the UE using the sTTI configuration information. In this case, for the first two subframes, the base station will use the sTTI to schedule the UE, and the UE needs to perform blind detection of sDCI. For the other eight subframes, the base station will either use a 1ms TTI to schedule the UE or not schedule the UE at all.

[0062] In a specific implementation, when the time interval information of the application of the sTTI includes the period information of the base station scheduling the UE with the sTTI, and the location indication information of the UE scheduling with the sTTI in each period, the UE can detect the downlink control signaling at the first position in each period based on the sTTI configuration information.

[0063] The first position may include: the identified subframe, and a first number of subframes, time slots or sTTIs following the identified subframe; or, the identified time slot, and a first number of subframes, time slots or sTTIs following the identified time slot.

[0064] Taking a 10ms period for sTTI as an example, the base station indicates in the sTTI configuration information that the time slot for scheduling the UE using the sTTI is the first time slot in each period. At this time, when the UE learns that the base station uses sTTI to schedule itself in the first time slot of the 10ms period, it means that the base station has low-latency data to send, so the UE can continue to detect sDCI in the next time slot (or several time slots or several subframes).

[0065] In one embodiment of the present invention, in order to better schedule the UE, the sTTI configuration information sent by the base station may further include: start indication information for applying the sTTI scheduling.

[0066] In specific implementations, the start indication information for applying the sTTI scheduling can be either the trigger signaling for applying the sTTI scheduling or the start subframe or time slot information for applying the sTTI scheduling; there are no specific limitations. After receiving the start indication information for applying the sTTI scheduling, the UE can detect the sDCI within the corresponding sTTI according to the sTTI configuration information and perform data transmission according to the detected sDCI, including receiving downlink data and performing uplink data transmission according to the sDCI indication.

[0067] For UEs that support sTTI scheduling, after receiving the sTTI configuration information sent by the base station, the base station can use sDCI to schedule the UE to ensure timely transmission of low-latency data. In embodiments of the present invention, the low-latency data typically refers to data with a transmission latency of less than 50ms, where transmission latency refers to the time delay of data transmission between the UE and the core network.

[0068] In practice, the sDCI typically contains resource configuration information for downlink data transmission, such as modulation and coding formats and the location information of allocated physical resource blocks. After decoding the sDCI, the UE receives downlink data or transmits uplink data based on the resource configuration information it contains.

[0069] In practice, after the current low-latency data transmission is completed, there may be no low-latency data transmission for a long time. If the UE is required to continuously detect sDCI during this period, it will lead to an increase in processing complexity and power consumption.

[0070] In one embodiment of the present invention, to further reduce the processing complexity and power consumption of the UE, when no downlink control signaling is detected within a preset time period based on the sTTI configuration information, the sTTI is suspended and the sTTI configuration information is retained. The preset time period may include multiple subframes or multiple sTTIs. The specific number of subframes or sTTIs is not limited. The preset time period can be configured by the base station.

[0071] After suspending the sTTI, the data transmission method further includes: when there is low-latency data to be transmitted, sending an indication to the base station to resume sTTI scheduling, and detecting downlink control signaling in the corresponding sTTI according to the sTTI configuration information to perform data transmission.

[0072] For example, when a UE has uplink low-latency data to send, the UE can indicate to the base station that it has low-latency data to send through a Buffer Status Report (BSR). The UE can immediately detect sDCI after sending the corresponding BSR, or wait to receive the indication information sent by the base station to reapply the sTTI before detecting sDCI.

[0073] After the sTTI is suspended, if the base station needs to transmit downlink low-latency data, the base station can send an indication message to the UE to reapply the sTTI via signaling, instructing the UE to resume sTTI scheduling.

[0074] In one embodiment of the present invention, since Medium Access Control (MAC) control signaling transmission is faster than RRC signaling and more reliable than DCI, the base station can use MAC layer control signaling to notify the UE to resume sTTI scheduling. Upon receiving this, the UE immediately detects sDCI in order to receive low-latency data in a timely manner.

[0075] As can be seen from the above, the data transmission method in this embodiment of the invention can effectively avoid a significant increase in processing complexity and power consumption of the UE when applying sTTI by setting the time interval information for applying sTTI in the sTTI configuration information sent by the base station.
