Description

Communication method and device, and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 29, 2023, with application number 202311101923.1 and invention name “Communication method and device, computer-readable storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art

[0003] The future sixth-generation mobile communication technology system (6th generation mobile networks or 6th generation wireless systems, 6G) may have two features: one is the use of multiple discontinuous bandwidths, and the other is the introduction of simultaneous full-duplex technology on the same frequency.

[0004] The use of multiple discontinuous bandwidths is driven by the fact that 6G will pursue higher data rates, which inevitably require higher transmission bandwidths. However, the spectrum resources controlled by various operators are not necessarily contiguous and may consist of multiple fragmented bandwidth resources. Simultaneous full-duplex technology emerged because it can greatly improve the utilization efficiency of time and frequency resources, ideally even doubling the efficiency.

[0005] However, there is currently no corresponding solution for resource indication for simultaneous co-frequency duplexing in non-contiguous spectrum scenarios.

[0039] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0040] In the technical solution of the present application, the terminal device receives first configuration information, and the first configuration information is used to indicate the duplex type on each frequency domain resource unit; uplink transmission, downlink transmission and / or simultaneous uplink and downlink transmission are performed according to the duplex type configuration information. In the technical solution of the present application, the terminal device obtains the duplex type on each frequency domain resource unit by receiving the first configuration information, and the duplex type on the time domain resource can be obtained by traditional means, or the duplex type on the time domain resource is pre-agreed, so that the terminal device can determine the resources for performing simultaneous and same-frequency full-duplex transmission, or other half-duplex transmission resources, to ensure the smooth development of communication services.

The technical solution of the present application independently configures the two duplex types of uplink and downlink, and the frequency domain resource units for full duplex are the overlapping frequency domain resource units in the first frequency domain resource unit set and the second frequency domain resource unit set, thereby improving the flexibility of configuration.

[0043] In the technical solution of the present application, a terminal device receives high-level signaling, which includes at least one duplex configuration, wherein multiple resource units reuse at least one duplex configuration. By multiplexing at least one duplex configuration across multiple resource units, the technical solution of the present application can reduce signaling overhead by indicating the duplex type on the resource unit.

[0044] Furthermore, in the technical solution of the present application, multiple consecutive resource units have the same duplex type, or resource units located in the same frequency band have the same duplex type. Through the above settings, the same duplex configuration in the same signaling can be applied to multiple consecutive resource units or resource units located in the same frequency band, saving signaling overhead.

[0045] Furthermore, in the technical solution of the present application, high-level signaling includes identifiers of multiple duplex type sets and their associated resource units. By carrying the identifiers of duplex type sets and their associated resource units in high-level signaling, the present application eliminates the need for separate and repeated signaling for resource units with the same duplex configuration, thereby saving signaling overhead.

[0046] Furthermore, in the technical solution of the present application, high-layer signaling includes a first matrix and / or a second matrix for target time-frequency resources, each first element in the first matrix indicates whether the duplex type is uplink or flexible, each second element in the second matrix indicates whether the duplex type is downlink or flexible, and each first element or second element corresponds to a time-frequency resource unit. By configuring the first matrix and the second matrix, the present application can implement configuration of multiple duplex types, including uplink, downlink, flexible, and full-duplex, avoiding the separate configuration of each duplex type and saving signaling overhead.

[0059] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, Long Term Evolution (LTE) systems, fifth-generation (5G) systems, new radio (NR) systems, 6G systems, and future evolution systems or multiple communication convergence systems.

[0060] This application mainly relates to the communication between terminal devices and network devices. Among them:

[0061] The network device in the embodiment of the present application may also be referred to as an access network device, for example, a base station (BS) (also referred to as a base station device), which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in the second generation (2nd-Generation, 2G) network, the device providing the base station function includes a base transceiver station (Base Transceiver Station, BTS), in the third generation (3rd-Generation, 3G) network, the device providing the base station function includes a node B (NodeB), in the fourth generation (4th-Generation, 4G) network, the device providing the base station function includes an evolved node B (evolved NodeB, eNB), in the wireless local area network (Wireless Local Area Networks, WLAN), the device providing the base station function is an access point (Access Point, AP), and the device providing the base station function in NR is the next generation Node Base station (gNB), and the further evolved node B (ng-eNB), wherein the gNB and the terminal device communicate using NR technology, and the ng-eNB and the terminal device communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network device in the embodiment of the present application also includes a device that provides a base station function in a future new communication system, etc.

[0062] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or user devices. The terminal equipment may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc., and the embodiments of the present application are not limited thereto. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0063] As described in the background art, there is currently no corresponding solution for resource indication for simultaneous co-frequency duplexing in a non-contiguous spectrum scenario.

[0064] Specifically, the current duplex technology in version (Rel-18) implements the base station side sub-band full-duplex (SBFD) method. At this time, the base station can simultaneously transmit in multiple directions in different frequency bands on a bandwidth part (BWP).

[0065] The judgment on the future evolution of full-duplex technology is as follows: the overall trend is divided into four stages. Taking into account the differences in base station types deployed by different operators and the differences in duplex types supported by terminal devices themselves, there can be different permutations and combinations.

[0066] When one side uses the same frequency and full-duplex mode, the combined duplex modes on the network and terminal sides can be divided into the following five categories:

[0067] Category 1: full-duplex on the same frequency and at the same time on the network side, and half-duplex on the terminal device side, such as frequency division duplexing (FDD) or time division duplexing (TDD).

[0068] Category 2: simultaneous and same-frequency full-duplex on the network side and sub-band half-duplex on the terminal device side.

[0069] Category 3: simultaneous same-frequency full-duplex on the network side and simultaneous same-frequency full-duplex on the terminal device side.

[0070] Category 4: half-duplex on the network side and full-duplex on the terminal device side at the same time and frequency.

[0071] Category 5: sub-band full-duplex on the network side and simultaneous same-frequency full-duplex on the terminal side.

[0072] The scenarios described in categories 3 and 4 may be that a terminal device is roaming, where an advanced terminal device roams into a relatively backward mobile network. The technical solution of the present application can be used in any of the above five scenarios.

[0073] In the technical solution of the present application, the terminal device obtains the duplex type on each frequency domain resource unit by receiving the first configuration information, and the duplex type on the time domain resource can be obtained through traditional methods, or the duplex type on the time domain resource is pre-agreed, so that the terminal device can determine the resources for performing simultaneous and same-frequency full-duplex transmission, or other half-duplex transmission resources, to ensure the smooth development of communication services.

[0074] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0075] Referring to FIG1 , the method provided in this application specifically includes the following steps:

[0076] Step 101: The network device sends first configuration information. Correspondingly, the terminal device receives the first configuration information. The first configuration information is used to indicate the duplex type of each frequency domain resource unit.

[0077] Step 102: The terminal device and the network device perform uplink transmission, downlink transmission and / or simultaneous uplink and downlink transmission according to the first configuration information.

[0078] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0079] It is understood that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated within a chip or chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0080] In the embodiment of the present invention, the duplex type can be configured independently for each frequency domain resource unit. Specifically, the duplex type can be configured for each frequency domain resource unit one by one.

[0081] Furthermore, the frequency domain resource unit can be the size of the frequency domain resources occupied by the resource block (RB), the size of the frequency domain resources occupied by the resource element (RE), the size of the frequency domain resources occupied by an integer multiple of RB, the size of the frequency domain resources occupied by an integer multiple of RE, or a subband, etc.

[0082] This embodiment of the present invention configures the duplex type for frequency-domain resources. In the time domain, the duplex type applies to the entire time domain. That is, the duplex type for a frequency-domain resource unit applies to all time-domain resource units. For example, if the duplex type for subband 1 is simultaneous, same-frequency, full-duplex, then the duplex type for all time-domain resources corresponding to subband 1 is simultaneous, same-frequency, full-duplex.

[0083] In this embodiment, a unified resource grid is used to cover a larger bandwidth. For example, if a 500MHz bandwidth is actually required, it can be covered by 800MHz or an unlimited bandwidth. The granularity of the resource grid can be RB / RE or larger resource units. Within the resource grid, some resource units (blocks) can be set as unavailable.

[0084] Figure 2 shows a duplex configuration of frequency domain resources on the network side. As can be seen from Figure 2, in addition to the unavailable bandwidth, the frequency domain resources available on the network side include fragmented bandwidth-1, fragmented bandwidth-2, fragmented bandwidth-3, and fragmented bandwidth-4. Among them, the duplex type on fragmented bandwidth-1 and fragmented bandwidth-3 is full-duplex, the duplex type of fragmented bandwidth-2 is downlink (also called half-duplex downlink), and the duplex type of fragmented bandwidth-4 is uplink (also called half-duplex uplink). Among them, the frequency band within the fragmented bandwidth is continuous, but different fragmented bandwidths can be discontinuous or continuous.

[0085] Among them, on some sub-bands with bandwidths less than the preset bandwidth, the network side can adopt a simultaneous, same-frequency, full-duplex configuration. Conversely, on some sub-bands with bandwidths greater than or equal to the preset bandwidth, the network side can adopt a traditional half-duplex configuration (i.e., only downlink or only uplink). This is because full-duplex has higher requirements for anti-interference capabilities, and the magnitude of anti-interference capabilities is inversely proportional to the sub-band bandwidth. Therefore, in order to ensure communication quality, the network side can adopt a simultaneous, same-frequency, full-duplex configuration on sub-bands with bandwidths less than the preset bandwidth. Among them, the preset bandwidth can be determined in a predefined manner, or the value of the preset bandwidth can be determined based on the full-duplex capability of the network-side device or the terminal device.

[0086] Similarly, on the terminal device side, on some sub-bands with a bandwidth less than the preset bandwidth, the terminal device can adopt a simultaneous and same-frequency full-duplex configuration; conversely, on some sub-bands with a bandwidth greater than or equal to the preset bandwidth, the terminal device can adopt a traditional half-duplex configuration.

[0087] In a non-limiting embodiment, the network device may inform the terminal device of its capabilities via broadcast signaling or Radio Resource Control (RRC) signaling. Specifically, the network device's capabilities include the bandwidth / frequency / sub-band that the network device supports for simultaneous, same-frequency, full-duplex communication.

[0088] In a non-limiting embodiment, the terminal device may also consider informing the network device of its capabilities through high-layer signaling by reporting its capabilities. Specifically, the capabilities of the terminal device include the bandwidth and / or center frequency and / or sub-band supported by the network device for simultaneous full-duplex communication.

[0089] Furthermore, when reporting its capabilities, terminal devices can also report their device type. For terminal devices that support simultaneous, same-frequency, full-duplex, their device type is different from that of other terminal devices that support half-duplex or SBFD. In other words, terminal devices that support simultaneous, same-frequency, full-duplex have a new device type. This new device type can be considered an enhancement of TDD / FDD or SBFD.

[0090] It should be noted that the new device type of the above-mentioned terminal device can be any other feasible name and can be specified in the communication standard protocol, and this application does not impose any restrictions on this.

[0091] For details, please refer to Figure 3, which shows a duplex configuration of frequency domain resources on the terminal side. In Figure 3a, the duplex type on fragmented bandwidth-3 is full duplex. In Figure 3b, the duplex type on fragmented bandwidth-1 is full duplex.

[0092] In one non-limiting embodiment, the duplex type is selected from uplink, downlink, and full-duplex.

[0093] Specifically, full-duplex can include simultaneous same-frequency full-duplex and time-division duplex. Then, when the terminal device learns from the first configuration information that the full-duplex type is full-duplex, it is necessary to further distinguish between same-frequency full-duplex and time-division duplex.

[0094] Method 1: The terminal device receives second configuration information, where the second configuration information is used to indicate that the duplex type of the first frequency domain resource unit is time division duplex or simultaneous frequency full duplex.

[0095] For example, the second configuration information occupies one bit. When the value of this bit is 1, it indicates that the duplex type is simultaneous and same-frequency full-duplex; when the value of this bit is 0, it indicates that the duplex type is time division duplex. The reverse is also true: when the value of this bit is 0, it indicates that the duplex type is simultaneous and same-frequency full-duplex; when the value of this bit is 1, it indicates that the duplex type is TDD.

[0096] In method 2, the terminal device distinguishes the duplex mode based on the time-domain time division duplex configuration of the first frequency-domain resource unit. For example, whether the frequency-domain resource unit is configured with legacy TDD-DL-UL-SlotConfiguration, if yes, indicates that the duplex mode is TDD; otherwise, it indicates that the duplex mode is simultaneous, same-frequency, full-duplex.

[0097] Referring to Figure 4, using the frequency domain resource unit as a subband as an example, the network device can configure the duplex type for subband 1 to be downlink (D), the duplex type for subband 2 to be simultaneous, same-frequency, full-duplex (D+U), the duplex type for subband 3 to be downlink (D), and the duplex type for subband 4 to be uplink (U). The numerology for each subband can be configured independently. Subband 1 and subband 2 are the subbands for UE1, subbands 2-4 are the subbands for UE2, and subbands 1-4 are the subbands for UE3.

[0098] A terminal device can obtain the duplex configuration of all subbands or only the duplex configuration of the subband it is in. For example, UE1 can obtain the duplex types of subbands 1 to 4 or only the duplex types of subbands 1 and 2. The duplex configuration can be UE-specific or cell-specific.

[0099] In a non-limiting embodiment, the first configuration information includes common configurations on multiple frequency domain resource units and dedicated configurations for a target frequency domain resource unit, where the dedicated configuration includes full duplex.

[0100] 4 , for subbands 1 to 4, the general configuration is DDDU (indicating duplex types of downlink, downlink, downlink, and uplink, respectively). For subband 2 (target frequency domain resource unit), a dedicated configuration (D+U) can be configured.

[0101] Specifically, the network device may send cell-specific high-layer signaling to the terminal device, where the cell-specific high-layer signaling includes the common configuration. The network device may also send device-specific high-layer signaling to the terminal device, where the device-specific high-layer signaling includes the dedicated configuration. In the embodiment shown in Figure 4 , the network device sends high-layer signaling to UE1, UE2, and UE3, respectively, to notify them of the dedicated configuration for subband 2.

[0102] In another non-limiting embodiment, the first configuration information includes a first set of frequency domain resource units whose duplex type is uplink, and a second set of frequency domain resource units whose duplex type is downlink.

[0103] In this embodiment, frequency domain resource units with uplink and downlink duplex types are configured independently.

[0104] 5 , taking the frequency domain resource unit as a subband as an example, the first frequency domain resource unit set is {subband 2, subband 3, subband 4}, and the second frequency domain resource unit set is {subband 1, subband 2, subband 3}.

[0105] Furthermore, the duplex type of the overlapping frequency domain resource units in the first frequency domain resource unit set and the second frequency domain resource unit set is full duplex. Continuing with FIG5 , the overlapping subbands in the first frequency domain resource unit set and the second frequency domain resource unit set are subband 2 and subband 3, and the duplex type of subband 2 and subband 3 is full duplex.

[0106] It should be noted that when the duplex type is full-duplex, the method for further distinguishing TDD from simultaneous same-frequency full-duplex can refer to the aforementioned method 1 and method 2, which will not be repeated here.

[0107] In a non-limiting embodiment, the first configuration information may be carried in high-layer signaling or dynamic indication signaling, wherein the high-layer signaling may specifically be RRC signaling, broadcast signaling, etc. The dynamic signaling may specifically be DCI.

[0108] The above embodiments mainly describe how to configure the duplex type in the frequency domain. Regarding how to configure the duplex type in time domain resources, one approach is to configure the duplex type for each frequency domain resource unit across the entire time domain. Another approach is to also configure the duplex type for each time domain resource unit.

[0109] In a specific embodiment, the duplex type of a time-frequency resource unit is configured using a first matrix and a second matrix. Each first element in the first matrix indicates whether the duplex type is uplink or flexible, and each second element in the second matrix indicates whether the duplex type is downlink or flexible. Each first element or second element corresponds to a time-frequency resource unit. Flexible means that the time-frequency resource can be uplink or downlink, which may depend on scheduling information and / or some predefined transmission rules.

[0110] It should be noted that the time-frequency resource unit can be any feasible size such as RB, RE, integer multiples of RB or integer multiples of RE, and this application does not impose any restrictions on this.

[0111] Furthermore, if the first element corresponding to the same time-frequency resource unit indicates that the duplex type is uplink and the second element indicates that the duplex type is downlink, the duplex type of the time-frequency resource unit is full-duplex. The full-duplex may be simultaneous same-frequency full-duplex. Accordingly, if the first element corresponding to the same time-frequency resource unit indicates that the duplex type is uplink and the second element indicates that the duplex type is flexible, the duplex type of the time-frequency resource unit is uplink or flexible. If the first element corresponding to the same time-frequency resource unit indicates that the duplex type is flexible and the second element indicates that the duplex type is downlink, the duplex type of the time-frequency resource unit is downlink or flexible.

[0112] Referring to FIG6 , the present application also discloses another communication method, which specifically includes the following steps:

[0113] Step 601: A network device sends a high-layer signaling, where the high-layer signaling includes at least one duplex configuration, wherein multiple resource units multiplex the at least one duplex configuration.

[0114] It should be noted that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0115] It is understood that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated within a chip or chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0116] The embodiment of the present invention multiplexes at least one duplex configuration in multiple resource units, thereby saving signaling overhead on the basis of indicating the duplex type on the resource unit.

Consecutive subbands 3 through 4 have the same full-duplex type. Consecutive subbands 5 through 7 have the same uplink duplex type.

[0121] In this embodiment, multiple consecutive sub-bands are located on the same bandwidth.

[0122] In a non-limiting embodiment, higher layer signaling is used to indicate that resource units located in the same frequency band have the same duplex configuration.

Correspondingly, if the first element corresponding to the same time-frequency resource unit indicates that the duplex type is uplink and the second element indicates that the duplex type is flexible, the duplex type of the time-frequency resource unit may be uplink. If the first element corresponding to the same time-frequency resource unit indicates that the duplex type is flexible and the second element indicates that the duplex type is downlink, the duplex type of the time-frequency resource unit may be downlink. If the first element corresponding to the same time-frequency resource unit indicates that the duplex type is undetermined and the second element indicates that the duplex type is undetermined, the duplex type of the time-frequency resource unit may be flexible.
