Description

Background Art

[0002] With the development of communication technology, it is stipulated in 3GPP TS 38.213 that uplink control information (UCI) can be transmitted simultaneously with data in the physical uplink shared channel (PUSCH) through methods such as puncturing and rate matching, which is also called multiplexing.

[0088] Explanation of the terms in the present disclosure.

[0089] Uplink Control Information (UCI): mainly includes uplink scheduling requests, hybrid automatic repeat requests, status indications, etc.

[0090] Orthogonal Cover Code (OCC): A set of orthogonal sequences. OCC allows multiple UEs to reuse the same time-frequency resources and can distinguish data from different UEs using the same time-frequency resources. The OCC group is a set of multi-user data with the same length as the OCC sequence. Figure 1 FIG. 4 shows one of the schematic diagrams of a transmission mode in an embodiment of the present disclosure, as Figure 1 shown, including UE1 and UE2, a total of 8 time slots (solt), the OCC sequence length is 2, the number of multiplexed users is 2, the number of repeated transmissions is 8, the transmitted information: for UE1 is A, for UE2 is B, two time slots form an OCC group, and OCC group 1 and OCC group 2 are respectively shown. The OCC sequence of UE1 is [1, 1], and the OCC sequence of UE2 is [1, -1].

[0091] Physical Uplink Control Channel (PUCCH): A physical channel used to transmit uplink control information.

[0092] Physical Uplink Shared Channel (PUSCH): A physical channel used to transmit uplink user data and part of the control information.

[0093] Hybrid Automatic Repeat request - ACKnowledgement (HARQ-ACK): Used to confirm whether a downlink data packet (transmitted through PDSCH) is correctly received.

[0094] Channel State Information (CSI): Used to optimize downlink transmission parameters.

[0095] With the development of communication technology, it is stipulated in 3GPP TS 38.213 that uplink control information (UCI) can be simultaneously transmitted with data in the Physical Uplink Shared Channel (PUSCH) through puncturing, rate matching, etc., which is also called multiplexing. In a communication scenario, considering the limited system bandwidth factor, the current 3GPP protocol already supports introducing Orthogonal Cover Code (OCC) technology in PUSCH to further improve the uplink transmission capacity through multi-user multiplexing.

[0096] However, for PUSCH supporting OCC, multiplexing the UCI carried on the Physical Uplink Control Channel (PUCCH) onto the PUSCH will affect the transmission and the information cannot be correctly received according to the existing standard regulations.

[0097] Figure 2 Fig. 1 shows one of the transceiver processing schematic diagrams in the embodiments of the present disclosure. As Figure 2 shown, it is a schematic diagram of inter-slot OCC transceiver processing, including UE1 and UE2. In the time domain and frequency domain, the information a1 and b1 transmitted by the two UEs are processed through the OCC sequence and then through the Channel processing to complete the transceiver. Here, Rx represents Receive and Tx represents Transmit.

[0098] After in-depth consideration by the inventors, for PUSCH supporting OCC, multiplexing the UCI carried on the PUCCH onto the PUSCH Figure 3 Fig. 2 shows another transceiver processing schematic diagram in the embodiments of the present disclosure. Taking UE1 in slot1 as an example, after the UCI is superimposed on the PUSCH of the UE, the overall orthogonality will be destroyed, as Figure 3 shown, and the data cannot be correctly received according to the existing standard regulations, which will affect both the UCI and PUSCH transmissions. In the related art, there is no relevant research and standard definition on how to multiplex the PUSCH supporting OCC with the PUCCH carrying the UCI.

[0099] Based on the above problems and in-depth consideration by the inventors of the present disclosure, embodiments of the present disclosure provide an information transmission method and related devices, which relate to the field of communication technologies. The method includes: determining the orthogonal cover code (OCC) sequence used for the transmission of the Physical Uplink Shared Channel (PUSCH) according to the configuration or indication of the network side, determining the time slots where the Physical Uplink Control Channel (PUCCH) carrying the uplink control information (UCI) overlaps with the PUSCH, and / or determining the resources where the UCI is multiplexed onto the PUSCH, and performing information transmission. By determining the overlapping time slots and / or the multiplexed resources of the UCI, the orthogonality between the information is avoided from being destroyed during the information transmission, so that the PUCCH carrying the UCI can be multiplexed with the PUSCH supporting OCC, thereby further improving the satellite communication uplink capacity.

[0100] Figure 4 Fig. 3 shows a schematic diagram of the structure of a communication network applicable in the embodiments of the present disclosure. The communication system includes a terminal 101, a terminal 102, and a network side device 103.

[0101] The terminals 101 and 102 can be, but are not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. It also includes new forms of terminal devices, such as drones, satellite communication terminals, etc. Essentially, they are all devices that receive electromagnetic waves sent by network devices for communication, and are not limited here. So far, the present disclosure has been described in detail. To avoid obscuring the concept of the present disclosure, some details well known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.

[0102] Among them, the network-side device 103 can be a base transceiver station (BTS) in Global System of Mobile communication (GSM) or Code Division Multiple Access (CDMA), or a Node B (NB) in Wideband Code Division Multiple Access (WCDMA), or an evolved base station (eNB or eNodeB) in LTE, or a Next Generation Radio Access Network (NGRAN) device, or a base station (gNB) in the New Radio (NR) system, or a radio controller in a Cloud Radio Access Network (CRAN), or the access network device can be a relay station, access point, in-vehicle device, wearable device, hub, switch, bridge, router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc., and is not limited here.

[0103] The terminals 101, 102 and the network-side device 103 can perform information transmission. The specific manner of information transmission is not limited in the embodiments of the present disclosure.

[0256] Embodiment 1: The first terminal device discards or does not transmit UCI, and the first terminal device uses the OCC sequence to transmit PUSCH on the overlapping time slot resources of some or all OCC groups, and discards or does not transmit UCI.

[0257] For the information transmission method performed by the second terminal device in the embodiment of the present disclosure, performing information transmission may include: using the OCC sequence to transmit PUSCH on the overlapping time slot resources of some or all OCC groups, and discarding or not transmitting UCI.

[0258] Embodiment 2: The first terminal device transmits UCI and does not transmit PUSCH. The second terminal device may correspond to multiple embodiments, which are not specifically limited in the present disclosure. The following content is used for illustration.

[0259] 1. The first terminal device does not transmit PUSCH and transmits UCI on the overlapping time slot resources within the OCC group with overlapping time slots.

[0260] For the information transmission method performed by the second terminal device in the embodiment of the present disclosure, performing information transmission may include: discarding or canceling PUSCH transmission on the overlapping time slot resources within the OCC group with overlapping time slots; and / or, canceling PUSCH transmission on the non-overlapping time slot resources within the OCC group with overlapping time slots, or using the original OCC sequence to perform PUSCH transmission, or not using the OCC sequence to perform PUSCH transmission; and / or, canceling PUSCH transmission within the OCC group without overlapping time slots, or using the original OCC sequence to perform PUSCH transmission.

[0261] In a possible embodiment, the first terminal device transmits UCI and does not transmit PUSCH on all time slot resources within the OCC group with overlapping time slots, and the second terminal device may discard all PUSCH transmissions within the OCC group with overlapping time slots.

[0262] 2. The first terminal device transmits UCI on all time slot resources within the OCC group with overlapping time slots and does not transmit PUSCH.

[0263] In the information transmission method performed by the second terminal device in the embodiments of the present disclosure, performing information transmission may include: canceling PUSCH transmission on the overlapping time slot resources within the OCC group with overlapping time slots, or performing PUSCH transmission using the original OCC sequence; and / or, canceling PUSCH transmission within the OCC group without overlapping time slots, or performing PUSCH transmission using the original OCC sequence.

[0264] 3. The first terminal device discards all PUSCH transmissions on all resources within all OCC groups, and transmits UCI on the overlapping time slot resources within the OCC group with overlapping time slots.

[0265] In the information transmission method performed by the second terminal device in the embodiments of the present disclosure, performing information transmission may include: discarding or canceling PUSCH transmission on the overlapping time slot resources within the OCC group with overlapping time slots; and / or, canceling PUSCH transmission on the non-overlapping time slot resources within the OCC group with overlapping time slots, or performing PUSCH transmission using the original OCC sequence, or performing PUSCH transmission without using the OCC sequence.

[0266] 4. The first terminal device discards all PUSCH transmissions on all resources within all OCC groups and transmits UCI on all resources.

[0267] In the information transmission method performed by the second terminal device in the embodiments of the present disclosure, performing information transmission may include: discarding or canceling all PUSCH transmissions, or performing PUSCH transmission using the original OCC sequence.

[0268] Embodiment 3: The first terminal device multiplexes UCI on PUSCH for transmission. For the second terminal device, there can be multiple corresponding embodiments, which are not specifically limited in the present disclosure. The following content is used for illustration.

[0269] 1. The first terminal device simultaneously transmits UCI and PUSCH on the overlapping time slot resources within the Nth OCC group after the OCC group with overlapping time slots, where N≥0 and N is an integer.

[0270] It should be noted that when N = 0, the first terminal device simultaneously transmits UCI and PUSCH on the overlapping time slot resources within the 0th OCC group after the OCC group with overlapping time slots. Taking the OCC group with overlapping time slots as OCC group 1, that is, on the resources of solt1 in OCC group 1.

[0271] It should be noted that the first terminal device can delay the transmission of UCI. Taking N = 1 as an example, in the overlapping time slot resources within the first OCC group after the OCC group with overlapping time slots (at this time, since the transmission of UCI is delayed, the time slot in which UCI is transmitted together with the information in the original PUSCH transmission is the overlapping time slot), UCI and PUSCH are transmitted simultaneously. The first OCC group after the OCC group with overlapping time slots is OCC group 2, so UCI and PUSCH are transmitted simultaneously on the resources of solt1 in OCC group 2.

[0272] For the second terminal device, the OCC group with overlapping time slots is OCC group 2, and the overlapping time slot resources are the resources on solt1 in OCC group 2.

[0273] In the information transmission method executed by the second terminal device in the embodiments of the present disclosure, the execution of information transmission may include: discarding or canceling PUSCH transmission on the overlapping time slot resources within the OCC group with overlapping time slots; and / or, canceling PUSCH transmission, or performing PUSCH transmission using the original OCC sequence, or not using the OCC sequence for PUSCH transmission on the non-overlapping time slot resources within the OCC group with overlapping time slots; and / or, canceling PUSCH transmission, or performing PUSCH transmission using the original OCC sequence within the OCC group without overlapping time slots.

[0274] In a possible embodiment, the first terminal device transmits UCI and PUSCH simultaneously on the overlapping time slot resources within the 0th OCC group after the OCC group with overlapping time slots, and does not use the OCC sequence for PUSCH transmission within the OCC group with overlapping time slots. The second terminal device discards or cancels all PUSCH transmissions on all time slot resources within the OCC group with overlapping time slots, and uses the original OCC sequence for PUSCH transmission within the OCC group without overlapping time slots.

[0275] In a possible embodiment, the first terminal device transmits UCI and PUSCH simultaneously on the overlapping time slot resources within the 0th OCC group after the OCC group with overlapping time slots, and does not use the OCC sequence for PUSCH transmission in all OCC groups. The second terminal device discards or cancels all PUSCH transmissions on all time slot resources in all OCC groups.

[0276] 2. The first terminal device transmits UCI and PUSCH simultaneously on all resources within the Nth OCC group after the OCC group with overlapping time slots, where N≥0 and N is an integer.

[0277] In the information transmission method performed by the second terminal device in the embodiments of the present disclosure, performing information transmission may include: canceling PUSCH transmission within an OCC group with overlapping time slots, or performing PUSCH transmission using the original OCC sequence; and / or, canceling PUSCH transmission within an OCC group without overlapping time slots, or performing PUSCH transmission using the original OCC sequence.

[0278] In a possible embodiment, the first terminal device simultaneously transmits UCI and PUSCH on all resources within the 0th OCC group after the OCC group with overlapping time slots, and all OCC groups perform PUSCH transmission using the OCC sequence. The second terminal device performs PUSCH transmission using the original OCC sequence in all OCC groups. The second terminal device performs PUSCH transmission using the original OCC sequence in all OCC groups.

[0279] 3. The first terminal device simultaneously transmits UCI and PUSCH on all resources within all OCC groups.

[0280] In the information transmission method performed by the second terminal device in the embodiments of the present disclosure, performing information transmission may include: discarding or canceling all PUSCH transmissions, or performing PUSCH transmission using the original OCC sequence.

[0281] In a possible embodiment, the network side device determines whether to notify the second terminal device according to the transmission mode of the first terminal device. For the transmission modes of the second terminal device in Embodiment 1, Embodiment 2-2 within the OCC group without overlapping time slots, Embodiment 3-2 within the OCC group without overlapping time slots, and Embodiment 3-3, the network side device may not need to notify the second terminal device for processing, and the transmission mode of the second terminal device may be determined by the second terminal device.

[0282] For other transmission modes other than the above transmission modes, for example, the transmission mode of Embodiment 3-2 within the OCC group with overlapping time slots, the network side device needs to notify the second terminal device, and the network side device may configure or indicate or implicitly indicate the second terminal device, which can be achieved through the fourth information.

[0283] Through the above method, the PUCCH carrying UCI and the PUSCH supporting OCC can be multiplexed, and the UCI and PUSCH transmissions can proceed normally, and information can be correctly received according to the existing standard regulations, thereby further improving the satellite communication uplink capacity.

[0284] The transmission methods in the above content are explained through the following embodiments and drawings. Taking the OCC sequence length of 2, the OCC sequences used by UE1 and UE2 are [1, 1] / [1, -1], and the PUSCH retransmission times are 8 as examples, different transmission methods are described.

[0287] The final transmission method is the same as the transmission method in Figure 1 , but the decision-making process is different. There may be an interaction process with the network-side device. For example, between UE1 and the network-side device, the network-side device can send the first information and the second information, and UE1 can send the third information, etc. Finally, UE1 adopts the transmission method in Figure 12 , or, the configuration of the first terminal device is different. UE1 finally adopts the transmission method in Figure 12 based on a predefined method. In this case, the network-side device may not send a notice to UE2.
