Description

[0001] Divisional application statement

[0002] This application is a divisional application based on the Chinese invention patent application with application number 201880000949.8, application date June 29, 2018, and invention name “Information transmission and reception method and device, base station and user equipment”. Technical Field

[0003] The present disclosure relates to the field of communication technologies, and in particular to an information transmission method and apparatus, an information receiving method and apparatus, a base station, a user equipment, and a computer-readable storage medium. Background Art

[0004] Narrowband Internet of Things (NB-IoT) is a very promising cellular Internet of Things technology that is widely used in many fields, such as smart cities, such as meter reading, smart agriculture, such as collecting information such as temperature and humidity, and smart transportation, such as shared bicycles.

[0005] Currently, an NB-IoT communication framework has been formed in Long Term Evolution (LTE), which has the characteristics of supporting low complexity or low cost, coverage enhancement and power saving.

[0006] To achieve the low complexity and low cost of NB-IoT, the communication bandwidth of NB-IoT terminals is only 180 kHz, corresponding to the physical resources of one physical resource block (PRB). To achieve the goal of enhancing NB-IoT coverage, NB-IoT introduces repeated transmission, that is, repeating the same content in consecutive subframes to achieve power accumulation.

[0007] Like traditional LTE, NB-IoT's downlink scheduling consists of two parts. The base station first sends a narrowband physical downlink control channel (NB-PDCCH) to the user equipment (UE). The NB-PDCCH contains scheduling information for subsequent service information transmission, such as the time-frequency position of the transmission, the coding method, etc. The service information subsequently transmitted is carried by another narrowband downlink shared channel (NB-PDSCH). In the current downlink scheduling, NB-PDCCH and NB-PDSCH must be carried on the same PRB. The PRB is configured by high-layer signaling. However, as the number of users increases, the communication load concentrated on one PRB will gradually increase, causing service congestion. At the same time, the increased communication load will also limit the flexibility of scheduling and bring about greater scheduling delays. Summary of the Invention

[0182] In the above embodiment, the PRB of the associated channel for transmitting the current PDCCH or the PRB for repeatedly transmitting the current PDCCH is determined. Since the determined PRB includes a PRB different from the current PRB used to transmit the current PDCCH, when the corresponding channel is transmitted through the determined PRB, service congestion due to excessive load on a certain PRB can be avoided, and the flexibility of scheduling can be improved.

[0183] Figure 2 This is a flow chart of an information receiving method shown in an exemplary embodiment of the present application. This embodiment is described from the UE side. Figure 2 As shown, the information receiving method includes:

[0184] In step S201, a current PDCCH is received on a current PRB.

[0185] In step S202, the DCI in the current PDCCH is parsed.

[0186] In step S203, if it is determined according to the analysis result that the base station transmits the associated channel of the current PDCCH on other PRBs, then the associated channel is correspondingly received on the other PRBs.

[0187] Among them, the associated channels of the current PDCCH may include but are not limited to the scheduled PDSCH of the current PDCCH, and may also include the PDCCH and its scheduled PDSCH that exceed the preset duration starting from the time point corresponding to the current PDCCH, and may also include the PDCCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH.

[0188] In this embodiment, if it is determined according to the analysis result that the base station transmits the associated channel of the current PDCCH on other PRBs, the associated channel can be correspondingly received on the other PRBs.

[0189] In the above embodiment, by receiving the current PDCCH on the current PRB, parsing the DCI in the current PDCCH, and determining based on the parsing result that the base station transmits the associated channel of the current PDCCH on other PRBs, the associated channel is received correspondingly on other PRBs, thereby avoiding service congestion due to excessive load on a certain PRB.

[0190] Example 1

[0191] Figure 3 This is a signaling flow chart of an information receiving method shown in an exemplary embodiment of the present application. Figure 3 As shown, the method includes:

[0192] In step S301, the base station determines a PRB set for transmitting a scheduled PDSCH for a current PDCCH.

[0193] The PRB set for transmitting the scheduled PDSCH of the current PDCCH may be determined according to the generated second configuration information, or the PRB set may be determined according to a preset rule.

[0194] In addition, optionally, after the PRB set is determined according to the generated second configuration information, the second configuration information may be sent to the UE through higher layer signaling.

[0195] In step S302, the base station sends the current PDCCH to the UE through the current PRB, and indicates the PRB in the PRB set used for transmission of the scheduled PDSCH through downlink control information (DCI) in the current PDCCH.

[0196] The PRBs used for transmission scheduling of PDSCH in the PRB set may be indicated in the following manner:

[0197] Mode 11) The information bit indication state in the DCI indicates the PRB used for transmission scheduling of the PDSCH, wherein different information bit indication states correspond one-to-one to different PRBs in the PRB set.

[0198] For example, the correspondence between the information bit indication state and the PRB established by the base station may be as shown in Table 1:

[0199] Table 1 Correspondence between information bit indication status and PRB

[0200] Information bit indication status PRB logo 00 PRB_1 01 PRB_2 10 PRB_3 11 PRB_4

[0201] Mode 12) The radio network temporary identifier RNTI value scrambled on the DCI cyclic redundancy check (CRC) indicates the PRB used for transmission scheduling of the PDSCH, wherein different RNTI values correspond one-to-one to different PRBs in the PRB set.

[0202] For example, the correspondence between the RNTI value and the PRB established by the base station may be as shown in Table 2:

[0203] Table 2 Correspondence between RNTI value and PRB

[0204] RNTI value PRB logo RNTI1 PRB_1 RNTI2 PRB_2 RNTI3 PRB_3 RNTI4 PRB_4

[0205] In step S303, the base station transmits the scheduled PDSCH of the current PDCCH through the indicated PRB.

[0206] In step S304, the UE receives the current PDCCH on the current PRB.

[0207] In step S305, the UE parses the DCI in the current PDCCH.

[0208] In step S306, if the UE obtains, according to the analysis result, that the PRB for transmitting the scheduled PDSCH of the current PDCCH is another PRB, the UE receives the scheduled PDSCH of the current PDCCH on the other PRB.

[0209] For example, if the current PDCCH is PDCCH1 and the current PRB is PRB1, the UE can receive PDCCH1 on PRB1 and parse PDCCH1 to obtain a parsing result, which may include the information bit indication status in the DCI or the RNTI value scrambled on the DCI CRC.

[0210] In this embodiment, the UE can determine the PRB set for scheduling PDSCH1 for transmitting PDCCH1 based on the received second configuration information or preset rules, and based on the determined PRB set and the above-mentioned analysis results, obtain that the PRB for scheduling PDSCH1 for transmitting PDCCH1 is other PRBs, such as PRB2, and the UE receives PDSCH1 on PRB2.

[0211] In the above embodiment, the interaction between the base station and the UE enables the UE to receive channels on different PRBs, thereby avoiding service congestion caused by excessive load on a certain PRB.

[0212] Example 2

[0213] Figure 4 This is a signaling flow chart of another information receiving method shown in an exemplary embodiment of the present application. Figure 4 As shown, the method includes:

[0214] In step S401, the base station determines a PRB set for transmitting a PDCCH and its scheduled PDSCH that starts at a time point corresponding to a current PDCCH and lasts for a predetermined duration.

[0215] Among them, the PRB set for transmitting PDCCH and its scheduled PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH can be determined according to the generated third configuration information, and the PRB set for transmitting PDCCH and its scheduled PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH can also be determined according to the preset rules.

[0216] In addition, optionally, after the PRB set is determined according to the generated third configuration information, the third configuration information may be sent to the UE through higher layer signaling.

[0217] In step S402, the base station sends the current PDCCH to the UE via the current PRB, and indicates through the DCI in the current PDCCH the PRB in the PRB set used to transmit the PDCCH and its scheduled PDSCH that start at the time point corresponding to the current PDCCH and last for a preset duration.

[0218] The PRBs in the PRB set used to transmit the PDCCH and its scheduled PDSCH that start at the time point corresponding to the current PDCCH and last for a predetermined period of time may be indicated in the following manner:

[0219] Method 21) The information bit indication status in the DCI indicates the PRB used to transmit the PDCCH and its scheduled PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH, where different information bit indication states correspond one-to-one to different PRBs in the PRB set.

[0220] Method 22) The RNTI value scrambled on the DCI CRC indicates the PRB used to transmit the PDCCH and its scheduled PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH, where different RNTI values correspond one-to-one to different PRBs in the PRB set.

[0221] In step S403, the UE receives the current PDCCH on the current PRB.

[0222] In step S404, the UE parses the DCI in the current PDCCH.

[0223] In step S405, if the UE obtains, based on the analysis result, that the PRB for transmitting the scheduled PDSCH of the current PDCCH is the current PRB and the PRB for transmitting the PDCCH and its scheduled PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH is other PRBs, then the scheduled PDSCH of the current PDCCH is received on the current PRB.

[0224] Among them, the UE can determine the PRB set used to transmit the PDCCH and its scheduled PDSCH for a period of more than a preset duration starting from the time point corresponding to the current PDCCH based on the received third configuration information or the preset rules, and obtain the PRB used to transmit the PDCCH and its scheduled PDSCH for a period of more than a preset duration starting from the time point corresponding to the current PDCCH based on the determined PRB set and the analysis result as other PRBs, and the analysis result includes the information bit indication status in the DCI or the RNTI value scrambled on the DCICRC.

[0225] Assume that the current PDCCH is PDCCH1, and the PDCCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH is PDCCH2. The PRB set determined by the base station for transmitting the PDCCH and its scheduled PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH is (PRB1, PRB2, PRB3, PRB4). The DCI in PDCCH1 indicates that the PRB in the PRB set used to transmit PDCCH2 and its scheduled PDSCH2 is PRB2. After the base station sends PDCCH1 to the UE on PRB1, if the UE receives PDCCH1, according to the analysis result of PDCCH1, it is obtained that the PRB used to transmit PDCCH1 and schedule PDSCH1 is PRB1 and the PRB used to transmit PDCCH2 and its scheduled PDSCH2 is PRB2, then PDSCH1 is received on PRB1.

[0226] In step S406, the UE performs HARQ feedback on the scheduled PDSCH.

[0227] In step S407, after receiving the HARQ feedback of the UE on the scheduled PDSCH, the base station transmits the PDCCH and its scheduled PDSCH on the indicated PRB, which start at the time point corresponding to the current PDCCH and last for more than a preset duration.

[0228] The UE performs HARQ feedback on the received PDSCH1. After receiving the HARQ feedback, the base station transmits PDCCH2 and PDSCH2 on PRB2.

[0229] In step S408, the UE receives, on other PRBs, a PDCCH and its scheduled PDSCH that start at a time point corresponding to the current PDCCH and last for more than a preset duration.

[0230] In the above embodiment, the interaction between the base station and the UE enables the UE to receive channels on different PRBs, thereby avoiding service congestion caused by excessive load on a certain PRB.

[0231] Example 3

[0232] Figure 5 This is a signaling flow chart of another information receiving method shown in an exemplary embodiment of the present application. Figure 5 As shown, the method includes:

[0233] In step S501, the base station determines, based on the generated first configuration information, the PRBs for repeatedly transmitting the PDCCH and its scheduled PDSCH that exceed a preset duration starting from the time point corresponding to the current PDCCH and the number of repeated transmissions of the corresponding channel on each PRB.

[0234] In which, the base station can determine the PRB used for repeated transmission of the corresponding channel based on the generated first configuration information, the first configuration information includes the interval between the PRB to be determined and the current PRB and one of the PRB indexes to be determined and the number of repeated transmissions of the corresponding channel on each PRB, the corresponding channel includes the PDCCH and its scheduling PDSCH that exceed the preset duration starting from the time point corresponding to the current PDCCH, or the PDCCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH.

[0235] Among them, the PRB used for repeated transmission of PDCCH with the time point corresponding to the current PDCCH as the starting point exceeding the preset duration and the PRB used for scheduling PDSCH for repeated transmission of PDCCH with the time point corresponding to the current PDCCH as the starting point exceeding the preset duration can be the same or different.

[0236] In step S502, the base station sends the current PDCCH to the UE via the current PRB, and carries the first configuration information via the scheduled PDSCH of the current PDCCH.

[0237] In step S503, the base station performs frequency hopping transmission on the corresponding channel on the determined PRB according to the number of repeated transmissions, wherein the corresponding channel refers to the PDCCH and its scheduled PDSCH that exceed the preset duration starting from the time point corresponding to the current PDCCH.

[0238] Assume that the current PDCCH is PDCCH1, the current PRB is PRB1, the PDCCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH is PDCCH2, the PRBs used for repeated transmission of PDCCH2 are PRB2 and PRB3, the PRBs used for repeated transmission of PDCCH2 scheduled PDSCH2 are PRB3 and PRB4, the number of repeated transmissions of PDCCH2 and PDCCH2 scheduled PDSCH2 on each PRB is 4 times, and the number of repeated transmissions of PDCCH2 and PDCCH2 scheduled PDSCH2 is 8 times, then the base station transmits PDCCH1 through PRB1, carries the first configuration information in PDSCH1, and then sends PDCCH2 repetition (repetition) #1 to PDCCH2 repetition #4 on PRB2, and sends PDCCH2 repetition #5 to PDCCH2repetition #8 on PRB3. Similarly, PDSCH2 repetition #1 to PDSCH2 repetition #4 are transmitted on PRB3, and PDSCH2 repetition #5 to PDSCH2 repetition #8 are transmitted on PRB4.

[0239] In step S504, the UE receives the current PDCCH on the current PRB.

[0240] In step S505 , the UE parses the DCI in the current PDCCH, obtains the scheduled PDSCH of the current PDCCH according to the parsing result, and obtains the first configuration information from the scheduled PDSCH.

[0241] In step S506, if the UE obtains at least two PRBs for repeatedly transmitting the PDCCH that exceeds the preset duration with the time point corresponding to the current PDCCH as the starting point according to the first configuration information, then the UE obtains the number of repeated transmissions of the PDCCH that exceeds the preset duration with the time point corresponding to the current PDCCH as the starting point on each PRB according to the first configuration information, and receives the repeated transmission of the PDCCH that exceeds the preset duration with the time point corresponding to the current PDCCH as the starting point on each obtained PRB according to the number of repeated transmissions.

[0242] In this embodiment, if the UE obtains at least two PRBs for repeated transmission of PDCCH2, such as PRB2 and PRB3, and the number of repeated transmissions of each channel on each PRB is 4 times, then 4 repeated transmissions of PDCCH2 can be received on PRB2 and 4 repeated transmissions of PDCCH2 can be received on PRB3.

[0243] In step S507, the UE combines and demodulates all received PDCCH information.

[0244] The UE combines and demodulates all received PDCCH information to obtain a DCI.

[0245] In step S508, if the UE obtains at least two PRBs for scheduling PDSCH for repeated transmission of PDCCH starting from the time point corresponding to the current PDCCH and exceeding a preset duration based on the demodulation result, then the UE receives the repeated transmission of the scheduled PDSCH on each currently obtained PRB according to the obtained number of repeated transmissions of the corresponding channel on each PRB.

[0246] Among them, if the UE obtains at least two PRBs for scheduling PDSCH2 for repeated transmission of PDCCH2 according to the demodulation result, for example, still PRB2 and PRB3, and the number of repeated transmissions of each channel on each PRB is 4 times, then 4 repeated transmissions of PDSCH2 can be received on PRB2 and 4 repeated transmissions of PDSCH2 can be received on PRB3.

[0247] In step S509, the UE combines and demodulates all received PDSCH information.

[0248] The UE can combine and demodulate all received PDSCH information to obtain information of a transport block.

[0249] In the above embodiment, through the interaction between the base station and the UE, the UE can repeatedly transmit a certain channel on different PRBs, thereby avoiding service congestion caused by excessive load on a certain PRB.

[0310] In the above embodiment, when the PRB for transmitting the scheduled PDSCH of the current PDCCH is obtained as other PRBs according to the analysis result, the scheduled PDSCH of the current PDCCH can be received on other PRBs, that is, the UE can transmit channels on different PRBs, thereby avoiding service congestion due to excessive load on a certain PRB.

[0311] Figure 20 is a block diagram of another information receiving device according to an exemplary embodiment. Figure 20 As shown in the above Figure 18 Based on the illustrated embodiment, the determination receiving module 73 may include: a second obtaining receiving submodule 732 and a third receiving submodule 733 .

[0312] The second receiving submodule 732 is configured to receive the scheduling PDSCH of the current PDCCH on the current PRB when the PRB for transmitting the scheduling PDSCH of the current PDCCH obtained according to the analysis result is the current PRB and the PRB for transmitting the PDCCH and its scheduling PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH is other PRBs.

[0313] The third receiving submodule 733 is configured to receive, on other PRBs, a PDCCH and its scheduling PDSCH that exceed a preset duration starting from a time point corresponding to the current PDCCH after performing hybrid automatic repeat request HARQ feedback on the scheduling PDSCH received by the second obtaining receiving submodule 732 .

[0314] Among them, the UE can determine the PRB set used to transmit the PDCCH and its scheduled PDSCH for a period of more than a preset duration starting from the time point corresponding to the current PDCCH based on the received third configuration information or the preset rules, and obtain the PRB used to transmit the PDCCH and its scheduled PDSCH for a period of more than a preset duration starting from the time point corresponding to the current PDCCH based on the determined PRB set and the analysis result as other PRBs, and the analysis result includes the information bit indication status in the DCI or the RNTI value scrambled on the DCICRC.

[0315] Assume that the current PDCCH is PDCCH1, and the PDCCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH is PDCCH2. The PRB set determined by the base station for transmitting the PDCCH and its scheduled PDSCH that exceeds the preset duration starting from the time point corresponding to the current PDCCH is (PRB1, PRB2, PRB3, PRB4). The DCI in PDCCH1 indicates that the PRB in the PRB set used to transmit PDCCH2 and its scheduled PDSCH2 is PRB2. After the base station sends PDCCH1 to the UE on PRB1, if the UE receives PDCCH1, according to the analysis result of PDCCH1, it is obtained that the PRB used to transmit PDCCH1 and schedule PDSCH1 is PRB1 and the PRB used to transmit PDCCH2 and its scheduled PDSCH2 is PRB2, then PDSCH1 is received on PRB1.

[0316] The UE performs HARQ feedback on the received PDSCH1. After receiving the HARQ feedback, the base station transmits PDCCH2 and PDSCH2 on PRB2.

[0317] The above embodiment enables the UE to receive channels on different PRBs, thereby avoiding service congestion caused by excessive load on a certain PRB.

[0320] In this embodiment, if the UE obtains at least two PRBs for repeated transmission of PDCCH2, such as PRB2 and PRB3, and the number of repeated transmissions of each channel on each PRB is 4 times, then 4 repeated transmissions of PDCCH2 can be received on PRB2 and 4 repeated transmissions of PDCCH2 can be received on PRB3.
