Description

Message sending method and device, and message receiving method

The present invention relates to the field of wireless communication technologies, and in particular, to a method and a device for sending a message, a method and a device for receiving a message, and a storage medium.

In the fourth-generation mobile communication long-term evolution (4G LTE) system, a physical uplink control channel (PUCCH) is used to transmit an uplink control message (UCI) from a UE to a base station (eNB). UCI includes Ack / Nack for physical downlink shared channel (PDSCH) transmission, channel status information (CSI), and scheduling request (SR) measured by user equipment (UE). PUCCH can be transmitted in a physical resource block (PRB) located at the edge of the bandwidth. UCI can also be carried by the physical uplink shared channel (PUSCH) together with the uplink data.

In the fifth generation mobile communication new wireless (5G NR) system, some new design requirements have emerged, requiring low latency and fast feedback. For example, a time slot can be divided into uplink and downlink sections. The downlink part consists of one or more symbols and can be sent from the gNB (which is similar to the eNB in LTE) to the UE at the beginning of the time slot. The downlink part is followed by the switching period (also known as the guard period GP), where the UE completes the handover from downlink reception to uplink transmission. Next is the uplink part, where the UE performs uplink transmission in one or more symbols. In order to obtain fast feedback (and thereby make turn around time faster), the UE may be required to give back Ack / Nack (and maybe other UCI) for the PDSCH carried by the downlink part in the same time slot. To this end, a new PUCCH is introduced in the NR, and it is transmitted at the end of a slot. Since the PUCCH can only occupy the last symbol or symbols of the time slot, it is called a PUCCH with a short duration (or a short format PUCCH, or short PUCCH for short).

In 5G NR systems, how to design transmission resources for PUCCH to achieve more flexible and efficient uplink message transmission is a problem to be solved.

The resource division and allocation provided by the embodiments of the present invention provide various flexible ways to support different design aspects of short PUCCH, including scalability, RS overhead, channel estimation, interference, and diversity.

Short PUCCH mainly contains Ack / Nack, and its payload is more than 1-2 bits. The desired design criterion is that short PUCCH has good scalability from low payload (1-2 bits) to high payload (> 2 bits). In addition, it is also desirable to be able to extend a short PUCCH with 1 symbol to a short PUCCH with 2 symbols (or possibly more than 2 symbols). Other aspects to consider include frequency diversity, power boost, good PUCCH capability, RS overhead, PAPR / CM, interference diversity, etc.

This embodiment of the present invention proposes several ways of allocating / configuring resource units / groups, which can be used in a very flexible manner for a short PUCCH in an NR system to send RS and UCI. This method is scalable to accommodate different payloads and is suitable for short PUCCH with one or more symbols. Some embodiments of the present invention also support frequency hopping, transmit diversity, and CDM multiplexing for different short PUCCHs.

FIG. 1 is a schematic flowchart of a message sending method according to an embodiment of the present invention. The message sending method of this embodiment is applied to a terminal side. As shown in FIG. 1, the message sending method includes the following operations shown in a box. The operation starts at block 101.

At block 101, the terminal sends an uplink message on at least one transmission resource, each transmission resource includes N resource groups, each resource group includes at least one resource unit, and N is a positive integer; wherein each of the resource groups in The resource units are evenly distributed in the frequency domain.

In some embodiments of the present invention, in the same resource group, different orthogonal sequences are used to send uplink messages of different terminals. In some embodiments of the present invention, in the same resource group, different orthogonal sequences are used to send uplink messages of different ports.

In some embodiments of the present invention, in the same time domain symbol, resource units in each resource group are evenly distributed in the frequency domain, and resource units from different resource groups are intertwined in the frequency domain.

In some embodiments of the present invention, one or more resource groups in at least one transmission resource are used to transmit RS or UCI.

Referring to FIG. 2, in order to meet these requirements and expectations, resources for short PUCCH can be divided into several groups. Figure 1 shows an example in which resources (also called resource elements RE) in a PRB are divided into three groups. The REs of each group are evenly distributed in frequency, and the REs of each group are interleaved with the REs of other groups. The resources of each group can be used to send a reference signal (RS) or UCI. For example, REs in group 1 can be used to carry RSs, while REs in groups 2 and 3 can be used to carry UCI. In order to have good channel estimation performance, RSs are expected to be evenly distributed in frequency, so REs from each group are intertwined. Short PUCCHs from different UEs can use Code Division Multiplexing (CDM) for multiplexing through this structure. For example, as shown in Figure 1, in a PRB, each group has 4 REs, so 4 orthogonal sequences (or quasi-orthogonal) of a certain length can be used (for example, in group 1) to multiplex 4 RSs from 4 UEs. Similarly, if QPSK is used for a short PUCCH, a 4-bit UCI can be carried, and 2 bits can be sent in each group (for example, in groups 2 and 3). In each group, four orthogonal quasi-orthogonal Gold sequences of a certain length can be used to propagate the UPS QPSK modulation symbols and multiplex with other short PUCCH UCI QPSK modulation symbols. In total, 4 short PUCCHs from 4 UEs can be covered and used in one resource group. This multiplexing method can also be used to implement transmit diversity. For example, if the UE has 2 transmit antenna ports and each transmit antenna port uses a different sequence, using the structure shown in Figure 1, a short PUCCH from two UEs (each UE has 2 transmit antennas) can be Overlays are used in the same resource group.

Figure 2 shows only one way to accomplish this. Figure 3 shows another grouping method, in which the REs in one PRB are divided into two groups instead of three. There are 6 REs in each group. For such packets, one group may be used to transmit RS and another group to be used to transmit UCI. Because there are 6 REs in each group, 6 orthogonal or quasi-orthogonal sequences can be used, and 6 short PUCCHs and their corresponding RSs are multiplexed in each group of a PRB. Alternatively, if transmit diversity is used and each antenna is assigned a separate sequence, a short PUCCH from 3 UEs (each UE has 2 transmit antenna ports) can be multiplexed on a PRB.

Referring to FIG. 4, the example shown in FIG. 4 uses one PRB as a resource unit. In fact, in order to multiplex more short PUCCHs, two alternatives can be used: one is to use frequency division multiplexing FDM, that is, to assign different PRBs to different short PUCCHs (here a PRB is considered a resource unit) And within each PRB, multiple short PUCCHs can be multiplexed using packetization and CDM. The second method is to use multiple PRBs as a resource unit. As shown in FIG. 3, for example, two PBRs can be used as a resource unit. The resources in this resource unit (2 PRBs) are divided into 3 groups, each group has 8 REs (in contrast, when When one resource unit is one PRB, each group has four REs. By doing so, longer orthogonal or quasi-orthogonal sequences can be used, which first improves channel estimation performance and secondly allows for each unit (now 8 for a resource unit and 4 for a PRB for a resource unit) More multiplexed short PUCCH. Of course, compared with the FDM method, the total PUCCH multiplexing capability is the same. Using longer resource units can also make interference more stable than shorter resource units.

As shown in FIG. 5, the resource grouping on the short PUCCH with 1 symbol can be extended to the short PUCCH with 2 symbols. Figure 4 shows an example in which the same resource grouping can be applied to these two symbols, the symbol N is the last symbol of the time slot, and the symbol N-1 is the penultimate symbol in the time slot. These resource groups can be used to carry RS or UCI. For example, groups 1 and 4 are used to carry RS, and other groups are used to carry UCI. Groups in different symbols can be used to carry the same type of signal or different types of signals. For example, if CDM is used in the time direction to improve the short PUCCH capability, the corresponding group of time-aligned symbols can be used to carry the same type of symbols. For example, groups 1 and 4 can be used to carry RSs, groups 2 and 5 can be used to carry the same UCI set, and groups 3 and 6 can be used to carry another UCI set. In this case, the Orthogonal Cover Code (OCC) can be further applied to each pair of REs that are temporally aligned for two symbols, as shown in FIG. 5. This will allow more PUCCHs to be multiplexed and double the ability of a 2-symbol short PUCCH on one PRB. If CDM is not applied in the time direction, each group on each symbol can be used to carry a different UCI. For example, group 1 on symbol N-1 can be used to carry RS, and groups 2, 3, 4, 5, 6 can be used to carry different UCI sets for the same UE. In addition, in each group, multiple short PUCCHs from different UEs can be multiplexed using the CDM method. Similar mechanisms / extensions can be used to construct short PUCCH structures on multiple symbols.

In some embodiments of the present invention, the transmission resource includes one or more orthogonal frequency division multiplexed OFDM symbols in the time domain.

As shown in FIG. 6, the resources for the 2-symbol short PUCCH can be directly grouped together instead of an extension of the grouping using the 1-symbol short PUCCH. FIG. 6 shows that the REs in 2 symbols are grouped together in time and frequency, instead of being grouped in the frequency direction on each symbol. Each group can then be assigned to send RS and UCI. For example, group 1 can be used to send RS, and groups 2 and 3 can be used to send modulated / spread UCI. The same content (for RS and UCI) can be used to transmit on a time-aligned pair of REs on different symbols, and OCC can be applied to each pair of REs in time to increase the short PUCCH capability.

In some embodiments of the present invention, when the terminal sends an uplink message on more than one transmission resource, the more than one transmission resource is located in different frequency domains and / or different time domain symbols.

As shown in Figures 7 and 8, an important aspect of short PUCCH design is the frequency diversity gain. This is particularly important considering the small number of symbols used to carry the PUCCH. To achieve this, frequency hopping can be used in the case where the same unit / group carrying the same UCI set of the UE can be sent separately in frequency. FIG. 7 shows an embodiment of how to implement frequency hopping on the same symbol, and FIG. 8 shows an embodiment of how to implement frequency hopping between two symbols. The latter case will also allow for a power boost because two frequency hopping opportunities are sent on two different symbols.

In addition, in addition to frequency diversity, other types of diversity schemes can also be used to improve the coverage of the short PUCCH. One diversity scheme is transmit diversity. As described above, one way to implement transmit diversity is to use different sequences for signals from different transmit antenna ports. Alternatively, other transmission diversity schemes can also be considered. In the case of using CDM to multiplex short PUCCHs from different UEs along the frequency direction, the SFBC scheme will destroy the sequence order, thereby destroying the orthogonality, and therefore may not be suitable for transmission diversity. One technique that can be considered is a frequency-switched transmit diversity (FSTD) scheme. Figure 9 shows an example where Group 1 can be used for RS transmission and the RS from each transmit antenna can use a different orthogonal sequence. Groups 2 and 3 are used to send the same UCI set from each antenna port. When group 2 is sent from antenna port # 1, the RE corresponding to group 3 on this antenna port is nulled, thereby avoiding interference with transmission from antenna port # 2, and when sending from antenna port # 2 In group 3, the RE corresponding to group 2 on the antenna port is nulled. One RE in each group is paired with one RE in the other group, where on each pair, the same modulation / spreading symbols (for example, S1, S2, S3, and S4 shown in FIG. 9) are changed from each Antenna ports. This scheme can be applied to short PUCCH with 1 symbol or 2 symbols.

For the 2-symbol short PUCCH, another transmit diversity scheme that can be considered is the space-time block code (STBC) scheme. Figure 10 shows an example. Groups 1 and 4 are still used for RS and CDM (for example, OCC in use time) can be used to create orthogonal RSs from each antenna port. The modulation and spreading symbols transmitted on each pair of REs aligned in time in groups 2 and 5 are encoded with STBC and transmitted from each antenna port. The same is true for the symbols sent on the corresponding RE pairs in groups 3 and 6. By applying the STBC scheme, the spreading sequences in each group remain orthogonal, so multiple short PUCCHs can be multiplexed using different orthogonal sequences. The STBC scheme generates two positive exchanges from each antenna port, which can avoid inter-stream interference. Therefore, compared with other transmit diversity schemes, it can achieve optimized transmit diversity gain. In addition, this solution does not require additional resources (sequences) to implement transmit diversity, and therefore maintains the same short PUCCH capability as a single antenna port, and a simple decoder at the gNB can be used to decode STBC.

In some embodiments of the present invention, the terminal receives a configuration message sent by the network device through semi-static signaling or dynamic signaling, and the configuration message is used to indicate a transmission resource of the uplink message. That is, the configuration of the resource units and groups (which may include the size of the resource units and groups, the number of groups in each unit, etc.) may be notified to the UE in a semi-static manner. Some groups can be used for RS transmission and other groups can be used for UCI. Such allocation can be semi-statically configured or dynamically indicated. Different units and groups can be used to send the same or different UCI. If the payload of the UCI increases, more units / groups can be allocated to different UCIs. To improve short PUCCH capabilities, more PRBs or longer units with more PRBs can be allocated. Generally, this resource division and allocation provides various flexible ways to support different design aspects of short PUCCH, including scalability, RS overhead, channel estimation, interference, diversity.
