Referring to fig. 1, fig. 1 is a block diagram of a wireless communication system to which an embodiment of the present invention is applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may also be referred to as a terminal Device or a User Equipment (UE), where the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device, and the specific type of the terminal 11 is not limited in the embodiment of the present invention. The network device 12 may be a Base Station or a core network, wherein the Base Station may be a 5G or later-version Base Station (e.g., a gNB, a 5G NR NB, etc.), or a Base Station in other communication systems (e.g., an eNB, a WLAN access point, or other access points, etc.), wherein the Base Station may be referred to as a node B, an evolved node B, an access point, a Base Transceiver Station (BTS), a radio Base Station, a radio Transceiver, a Basic Service Set (BSS), an Extended Service Set (ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, or some other suitable terminology in the field, as long as the same technical effect is achieved, the Base Station is not limited to a specific technical vocabulary, it should be noted that, in the embodiment of the present invention, only the Base Station in the NR system is taken as an example, but does not limit the specific type of base station.

The base stations may communicate with the terminals 11 under the control of a base station controller, which may be part of the core network or some of the base stations in various examples. Some base stations may communicate control information or user data with the core network through a backhaul. In some examples, some of the base stations may communicate with each other, directly or indirectly, over backhaul links, which may be wired or wireless communication links. A wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on the multiple carriers simultaneously. For example, each communication link may be a multi-carrier signal modulated according to various radio technologies. Each modulated signal may be transmitted on a different carrier and may carry control information (e.g., reference signals, control channels, etc.), overhead information, data, and so on.

The base station may communicate wirelessly with the terminal 11 via one or more access point antennas. Each base station may provide communication coverage for a respective coverage area. The coverage area of an access point may be divided into sectors that form only a portion of the coverage area. A wireless communication system may include different types of base stations (e.g., macro, micro, or pico base stations). The base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. The base stations may be associated with the same or different access networks or operator deployments. The coverage areas of different base stations (including coverage areas of base stations of the same or different types, coverage areas utilizing the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

The communication links in a wireless communication system may comprise an Uplink for carrying Uplink (UL) transmissions (e.g., from terminal 11 to network device 12) or a Downlink for carrying Downlink (DL) transmissions (e.g., from network device 12 to terminal 11). The UL transmission may also be referred to as reverse link transmission, while the DL transmission may also be referred to as forward link transmission.

As shown in fig. 2, the uplink data rate matching method according to the embodiment of the present invention is applied to a terminal side, and includes the following steps:

step 21: receiving at least one rate matching pattern, wherein the rate matching pattern comprises: and the indication information is used for indicating the reference signal and/or the target time-frequency domain resource where the uplink control region is located.

The rate matching pattern (pattern) may indicate transmission resources of a reference signal and/or an uplink control region, and the reference signal may include, but is not limited to: at least one of a Preamble (Preamble), a demodulation Reference Signal (DMRS), and a Phase Tracking Reference Signal (PTRS). The uplink control region refers to a resource for transmitting an uplink control signal.

Specifically, the indication information in the rate matching pattern may indicate the target time-frequency domain resource specifically by indicating identification ID information and/or location information of the target time-frequency domain resource. That is, the indication information specifically indicates identification ID information and/or location information of the target time-frequency domain resource. The identification ID information is a reference signal ID or a configuration parameter ID of a reference signal, or the identification ID information may also be an uplink control area ID, such as a time-frequency resource ID or a control area ID of the uplink control area. The terminal can determine the corresponding reference signal or the target time-frequency domain resource of the uplink control region according to the ID information. For example, the indication information indicates IDs of the DMRS configuration parameters, and if the network device configures a plurality of DMRS configuration parameters, indicates IDs of the plurality of DMRS configuration parameters. Or, the indication information indicates IDs of the PTRS configuration parameters, and if the network device configures a plurality of PTRS configuration parameters, indicates IDs of the plurality of PTRS configuration parameters.

Step 22: and performing rate matching of uplink data on the multiple access resources according to the at least one rate matching pattern.

The multiple access resource here refers to: the transmission resources multiplexed when a plurality of terminals perform non-orthogonal uplink transmission, that is, the resources where the uplink data channels of the terminals are located. Therefore, the terminal carries out the rate matching of the uplink data according to at least one rate matching pattern, so that the transmission resources of the reference signal and/or the uplink control area can be avoided when the uplink data is sent, and the resource conflict problem of non-orthogonal uplink transmission is avoided.

Wherein the rate matching pattern further comprises at least one of the following information:

the number information of the rate matching pattern is used for distinguishing different rate matching patterns;

period information of the rate matching pattern indicating a duration of the rate matching pattern or a cycle period of the rate matching pattern;

subcarrier spacing information.

Wherein, after the step 21, the method further comprises: when the indication information is used for indicating the target time-frequency domain resource where the reference signal is located, the terminal can determine the target time-frequency domain resource of at least one reference signal according to the indication information of one rate matching pattern; and determining target time-frequency resources of at least one of a preamble, a demodulation reference signal (DMRS) and a Phase Tracking Reference Signal (PTRS) according to the indication information in the rate matching pattern. For example, the indication information in the rate matching pattern indicates IDs of DMRS configuration parameters, and if the network device configures multiple DMRS configuration parameters, the terminal determines time-frequency resources of the multiple DMRSs according to the IDs of the multiple DMRS configuration parameters indicated by the network. Or, the indication information in the rate matching pattern indicates IDs of the PTRS configuration parameters, and if the network device configures multiple PTRS configuration parameters, the terminal determines time-frequency resources of the multiple PTRS according to the IDs of the multiple PTRS configuration parameters indicated by the network. When the indication information is used for indicating the target time-frequency domain resource where the reference signal is located, the indication information of one rate matching pattern is used for indicating the target time-frequency domain resource of at least one reference signal. Preferably, the indication information of one rate matching pattern is only used to indicate a target time-frequency domain resource of one reference signal, and then the terminal needs to determine the target time-frequency domain resources of multiple reference signals in conjunction with multiple rate matching patterns configured by the network device, so as to perform rate matching on the uplink data. For example: the rate matching pattern 1 is used to indicate time-frequency resources (or referred to as target time-frequency domain resources) of multiple DMRSs, and the rate matching pattern 2 is used to indicate time-frequency resources of one or more PTRSs. Alternatively, the indication information of one rate matching pattern may indicate target time-frequency resources of multiple non-orthogonal reference signals at the same time, for example, rate matching pattern 1 indicates time-frequency resources of one or more DMRSs and time-frequency resources of one or more PTRSs at the same time. It is to be noted that the number of a reference signal may be one or multiple, for example, the indication information of one rate matching pattern may indicate target time-frequency domain resources where at least two DMRSs are located.

It is worth noting that the frequency domain granularity of the target time-frequency domain resources of embodiments of the present invention is predefined or network device configured. The frequency domain granularity of the target time-frequency domain Resource is Resource Block (RB), Resource Element (RE), or the same as the frequency domain granularity of the uplink data.

The indication information in the rate matching pattern may specifically indicate the target time-frequency domain resource in a bitmap manner. Specifically, the indication information includes at least one bitmap, and multiple bitmaps directly and individually indicate or jointly indicate the target time-frequency domain resource location. The target time frequency resources of the multiple reference signals can be indicated by multiple bitmaps respectively or indicated by a bitmap jointly. For example, the target time domain resources of the one or more DMRSs may be indicated by one bitmap, and the target frequency domain resources of the one or more DMRSs may be indicated by one bitmap; or, jointly indicating target time-frequency resources of one or more DMRSs through a bitmap. The target time frequency resources of different reference signals can be indicated separately by using different bitmaps.

The rate matching pattern configured by the network device may be configured based on multiple access resources, that is, the rate matching pattern corresponding to each multiple access resource is configured independently. Specifically, the network device configures a rate matching pattern for each multiple access resource, that is, there is a correspondence between the multiple access resource and the rate matching pattern, and the terminal determines which resources in the multiple access resource cannot be used by the uplink data according to the rate matching pattern corresponding to the multiple access resource.

In addition, when the network device configures the rate matching pattern, it may not be based on each multiple access resource, that is, there is no corresponding relationship between the multiple access resource and the rate matching pattern, and when the terminal performs rate matching on uplink data of multiple different multiple access resources, it is based on the same rate matching pattern.

In the uplink data rate matching method of the embodiment of the invention, the terminal performs rate matching on the uplink data according to the rate matching pattern, so that collision with the reference signal and/or the transmission resource of the uplink control area can be avoided, the problem of resource collision of non-orthogonal uplink transmission can be solved, and the effectiveness of communication is improved.

Wherein the rate matching pattern further comprises: at least one of number information of the rate matching pattern, period information of the rate matching pattern, and subcarrier spacing information.

When the indication information is used for indicating the target time-frequency domain resource where the reference signal is located, the indication information of one rate matching pattern is used for indicating the target time-frequency domain resource of at least one type of reference signal.

Wherein the reference signal comprises: at least one of a preamble, a demodulation reference signal, DMRS, and a phase tracking reference signal, PTRS.

The indication information is used for indicating the identification ID information and/or the position information of the target time-frequency domain resource.

Wherein the frequency domain granularity of the target time-frequency domain resource is predefined or configured by the network device.

The frequency domain granularity of the target time-frequency domain resource is the same as the frequency domain granularity of the resource block RB, the resource element RE or the uplink data.

Wherein the indication information comprises at least one bitmap.

Wherein, the rate matching pattern corresponding to each multiple access resource is configured independently.

The rate matching pattern as referred to herein may indicate transmission resources of a reference signal and/or an uplink control region, and the reference signal may include, but is not limited to: at least one of a preamble, a demodulation reference signal, DMRS, and a phase tracking reference signal, PTRS. The uplink control region refers to a resource for transmitting an uplink control signal.

Specifically, the indication information in the rate matching pattern may indicate the target time-frequency domain resource specifically by indicating identification ID information and/or location information of the target time-frequency domain resource. That is, the indication information specifically indicates identification ID information and/or location information of the target time-frequency domain resource. The identification ID information is a reference signal ID or a configuration parameter ID of a reference signal, or the identification ID information may also be an uplink control area ID, such as a time-frequency resource ID or a control area ID of the uplink control area. The terminal can determine the corresponding reference signal or the target time-frequency domain resource of the uplink control region according to the ID information.

Step 52: uplink data rate-matched using at least one rate matching pattern is received.

Therefore, the terminal carries out the rate matching of the uplink data according to at least one rate matching pattern, namely, the transmission resources of the reference signal and/or the uplink control area can be avoided when the uplink data is sent, the problem of resource conflict of non-orthogonal uplink transmission is avoided, and the effectiveness of communication is improved.

Wherein the rate matching pattern further comprises at least one of the following information: number information of a rate matching pattern distinguishing different rate matching patterns, period information of the rate matching pattern indicating a duration of the rate matching pattern or a cycle period of the rate matching pattern, and subcarrier spacing information.

When the indication information is used for indicating the target time-frequency domain resource where the reference signal is located, the indication information of one rate matching pattern is used for indicating the target time-frequency domain resource of at least one reference signal. Preferably, the indication information of one rate matching pattern is only used to indicate a target time-frequency domain resource of one reference signal, and then the terminal needs to determine the target time-frequency domain resources of multiple reference signals in conjunction with multiple rate matching patterns configured by the network device, so as to perform rate matching on the uplink data. For example: the rate matching pattern 1 is used to indicate time-frequency resources (or referred to as target time-frequency domain resources) of multiple DMRSs, and the rate matching pattern 2 is used to indicate time-frequency resources of one or more PTRSs. Alternatively, the indication information of one rate matching pattern may indicate target time-frequency resources of multiple non-orthogonal reference signals at the same time, for example, rate matching pattern 1 indicates time-frequency resources of one or more DMRSs and time-frequency resources of one or more PTRSs at the same time. It is to be noted that the number of a reference signal may be one or multiple, for example, the indication information of one rate matching pattern may indicate target time-frequency domain resources where at least two DMRSs are located. It is worth noting that the frequency domain granularity of the target time-frequency domain resources of embodiments of the present invention is predefined or network device configured. When the frequency domain granularity is configured by the network device, step 51 is preceded by: and configuring the frequency domain granularity of the target time-frequency domain resource. Preferably, the frequency domain granularity of the target time-frequency domain resource is the same as the frequency domain granularity of the resource block RB, the resource element RE or the uplink data.

The indication information in the rate matching pattern may specifically indicate the target time-frequency domain resource in a bitmap manner. Specifically, the indication information includes at least one bitmap, and multiple bitmaps directly and individually indicate or jointly indicate the target time-frequency domain resource location.

Wherein the rate matching pattern configured by the network device may be based on a multiple access resource configuration, then before step 52, the method further includes: and respectively configuring corresponding rate matching patterns for each multiple access resource of the terminal. Therefore, the corresponding relation exists between the multiple access resources and the rate matching pattern, and the terminal determines which resources in the multiple access resources can not be used by the uplink data according to the rate matching pattern corresponding to the multiple access resources.

In the uplink data rate matching configuration method of the embodiment of the invention, the network equipment configures at least one rate matching pattern for the terminal, and the terminal performs rate matching on the uplink data according to the rate matching pattern, so that collision with a reference signal and/or transmission resources of an uplink control area can be avoided, the problem of resource collision of non-orthogonal uplink transmission can be solved, and the effectiveness of communication is improved.

The above embodiments respectively describe in detail the uplink data rate matching configuration method in different scenarios, and the following embodiments further describe the corresponding network device with reference to the accompanying drawings.

Wherein the indication information comprises at least one bitmap.

Wherein, the network device 600 further includes:

and the third configuration module is used for respectively configuring corresponding rate matching patterns for each multiple access resource of the terminal.

It is worth pointing out that, the network device in the embodiment of the present invention configures at least one rate matching pattern for the terminal, and the terminal performs rate matching on the uplink data according to the rate matching pattern, so as to avoid collision with the reference signal and/or the transmission resource of the uplink control region, and solve the resource collision problem of non-orthogonal uplink transmission, thereby improving the effectiveness of communication.
