Description

Technical Field

[0001] 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

[0002] There are two features that may appear in the future sixth generation mobile communication technology systems (6th generation mobile networks or 6th generation wireless systems, 6G). One feature is the use of multiple discontinuous bandwidths, and the other is the introduction of simultaneous same-frequency full-duplex technology.

[0003] The use of multiple discontinuous bandwidths is because 6G will pursue higher data transmission rates, which will inevitably require higher transmission bandwidths. However, the spectrum resources controlled by various operators are not necessarily continuous, and may be multiple fragmented bandwidth resources. The emergence of simultaneous full-duplex technology is because simultaneous full-duplex can greatly improve the utilization efficiency of time and frequency resources, and ideally can even double the effect.

[0037] Compared with the prior art, the technical solution of this application has the following beneficial effects:

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 resources can be obtained by traditional means, or the duplex type on the time domain resources 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.

[0041] In the technical solution of the present application, a terminal device receives high-level signaling, and the high-level signaling includes at least one duplex configuration, wherein multiple resource units reuse at least one duplex configuration. The technical solution of the present application can save signaling overhead on the basis of indicating the duplex type on the resource unit by multiplexing at least one duplex configuration on multiple resource units.

[0042] 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.

[0043] Furthermore, in the technical solution of the present application, the high-level signaling includes multiple duplex type sets and identifiers of their associated resource units. By carrying the identifiers of the duplex type sets and their associated resource units in the high-level signaling, the present application makes it unnecessary to send signaling separately and repeatedly for resource units with the same duplex configuration, thus saving signaling overhead.

By configuring the first matrix and the second matrix, the present application can realize the configuration of multiple duplex types such as uplink, downlink, flexible and full-duplex, avoiding the separate configuration of each duplex type and saving signaling overhead.

[0057] 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 wireless (NR) systems, 6G systems, and future evolution systems or multiple communication fusion systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system. The technical solution of the present application is also applicable to different network architectures, including but not limited to relay network architectures, dual-connection architectures, vehicle-to-everything communication architectures, and other architectures.

[0058] This application mainly relates to the communication between terminal equipment and network equipment. Among them:

[0059] The network device in the embodiment of the present application may also be referred to as an access network device, for example, it may be a base station (BS) (also referred to as a base station device), and the network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in the second-generation (2G) network, the equipment that provides base station functions includes the base transceiver station (BTS), in the third-generation (3G) network, the equipment that provides base station functions includes the node B (NodeB), and in the fourth-generation (4G) network, the equipment that provides base station functions includes the evolved node B (eNB). In wireless local area networks (WLAN), the equipment that provides base station functions is the access point (AP), and the equipment that provides base station functions in NR is the next generation Node Base station (gNB), as well as the evolved node B (ng-eNB), where 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 (Evolved Universal Terrestrial Radio Access, E-UTRA) technology, and both gNB and ng-eNB can be connected to the 5G core network. The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.

[0060] 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 (Mobile Station, 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 function, 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 evolving Public Land Mobile Network (PLMN), etc., which is not limited in the embodiments of the present application. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.

[0061] As described in the background technology, up to now, there is no corresponding solution for resource indication method for simultaneous same-frequency duplex in non-continuous spectrum scenario.

[0062] Specifically, the current duplex technology in version (Rel-18) implements the sub-band full-duplex (SBFD) method on the base station side. At this time, the base station can simultaneously transmit in multiple directions in different frequency bands on one bandwidth part (Band Width Part, BWP).

[0063] 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 the types of base stations deployed by different operators and the differences in the duplex types supported by the terminal devices themselves, there can be different arrangements and combinations.

[0064] When one side uses the same frequency and full-duplex type, the combined duplex type on the network side and the terminal device side can be divided into the following five categories:

[0065] 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 duplex (FDD) or time division duplex (TDD).

[0066] Category 2: simultaneous same-frequency full-duplex on the network side and sub-band half-duplex on the terminal equipment side.

[0067] Category 3: simultaneous same-frequency full-duplex on the network side and simultaneous same-frequency full-duplex on the terminal device side.

[0068] Category 4: half-duplex on the network side and full-duplex on the terminal device side at the same time and frequency.

[0069] Category 5: sub-band full-duplex on the network side and simultaneous same-frequency full-duplex on the terminal side.

[0070] The scenarios described in categories 3 and 4 may be that the terminal device is roaming, and 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.

[0071] In the technical solution of the present application, the terminal device obtains the duplex type of each frequency domain resource unit by receiving the first configuration information, and the duplex type of the time domain resources can be obtained through traditional methods, or the duplex type of the time domain resources is pre-agreed, so that the terminal device can determine the resources for executing simultaneous and same-frequency full-duplex transmission, or other half-duplex transmission resources, to ensure the smooth development of communication services.

[0072] 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.

[0073] See also Figure 1 The method provided in this application specifically includes the following steps:

[0074] 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 on each frequency domain resource unit.

[0075] 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.

[0076] It should be pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0077] It is understandable that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.

[0078] In the embodiment of the present invention, the duplex type may be configured independently for each frequency domain resource unit. Specifically, the duplex type may be configured for each frequency domain resource unit one by one.

[0079] 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.

[0080] The embodiment of the present invention is for the configuration of duplex type on frequency domain resources. In the time domain, the duplex type can be applied to the entire time domain, that is, the duplex type of the frequency domain resource unit can act on all time domain resource units. For example, if the duplex type of subband 1 is simultaneous same-frequency full-duplex, then the duplex type of the entire time domain resource corresponding to subband 1 is simultaneous same-frequency full-duplex.

[0081] 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 a larger resource unit. In the resource grid, some resource units (blocks) can be set as unavailable.

[0082] Figure 2 Figure 1 shows a duplex configuration of frequency domain resources on the network side. Figure 2 It can be seen that, 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.

[0083] Among them, on some sub-bands with bandwidth less than the preset bandwidth, the network side can adopt the configuration of simultaneous co-frequency full-duplex, on the contrary, on some sub-bands with bandwidth greater than or equal to the preset bandwidth, the network side can adopt the traditional half-duplex (i.e. only downlink or only uplink) configuration. This is because full-duplex has high requirements for anti-interference ability, and the size of the anti-interference ability is inversely proportional to the sub-band bandwidth. Therefore, in order to ensure the quality of communication, the network side can adopt the configuration of simultaneous co-frequency full-duplex on sub-bands with bandwidth 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 according to the full-duplex capability of the network side device or the terminal device.

[0084] Similarly, on the terminal device side, on some sub-bands with bandwidth less than the preset bandwidth, the terminal device can adopt the simultaneous same-frequency full-duplex configuration; conversely, on some sub-bands with bandwidth greater than or equal to the preset bandwidth, the terminal device can adopt the traditional half-duplex configuration.

[0085] In a non-limiting embodiment, the network device may inform the terminal device of its capabilities through broadcast signaling or Radio Resource Control (RRC) signaling. Specifically, the capabilities of the network device include the bandwidth / frequency / sub-band that the network device supports for simultaneous full-duplex on the same frequency.

[0086] In a non-limiting embodiment, the terminal device may also consider informing the network device of its capability report through high-level signaling. Specifically, the capability of the terminal device includes the bandwidth and / or center frequency and / or sub-band that the network device supports simultaneous full-duplex.

[0087] Furthermore, when reporting its capabilities, the terminal device can also report the type of device. For a terminal device that supports simultaneous full-duplex, its device type is different from other terminal devices that support half-duplex or terminal devices that support SBFD, that is, the terminal device that supports simultaneous full-duplex has a new device type. The new device type of the terminal device can be considered as an enhancement of TDD / FDD, or an enhancement of SBFD.

[0088] 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 limitation on this.

[0089] Please refer to Figure 3 , Figure 3 A duplex configuration of frequency domain resources on the terminal device side is shown. Figure 3 In a, the duplex type on fragment bandwidth-3 is full duplex. Figure 3 In b, the duplex type on the fragment bandwidth -1 is full duplex.

[0090] In one non-limiting embodiment, the duplex type is selected from uplink, downlink, and full-duplex.

[0091] Specifically, full-duplex may include simultaneous same-frequency full-duplex and time-division duplex. Then, when the terminal device learns through 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.

[0092] 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 full duplex.

[0093] For example, the second configuration information occupies one bit, and when the value of the bit is 1, it indicates that the duplex type is simultaneous same-frequency full-duplex; when the value of the bit is 0, it indicates that the duplex type is time division duplex. The reverse is also applicable, when the value of the bit is 0, it indicates that the duplex type is simultaneous same-frequency full-duplex; when the value of the bit is 1, it indicates that the duplex type is TDD.

[0094] Mode 2: The terminal device distinguishes based on the time division duplex configured in the time domain of the first frequency domain resource unit. For example, whether the legacy TDD-DL-UL-SlotConfiguration is configured on the frequency domain resource unit, if yes, it indicates that the duplex type is TDD, otherwise it indicates that the duplex type is simultaneous same-frequency full-duplex.

[0095] Please refer to Figure 4 Taking the frequency domain resource unit as subband as an example, the network device can configure the duplex type of subband 1 as downlink (D), the duplex type of subband 2 as simultaneous and co-frequency full duplex (D+U), the duplex type of subband 3 as downlink (D), and the duplex type of subband 4 as uplink (U). The parameter set (numerology) of each subband can be configured independently. Among them, subband 1 and subband 2 are the subbands where UE1 is located, subband 2-subband 4 are the subbands where UE2 is located, and subband 1-subband 4 are the subbands where UE3 is located.

[0096] For a terminal device, it can obtain the duplex configuration of all subbands, or only obtain the duplex configuration of the subband it is in. For example, for UE1, it can obtain the duplex type of subband 1 to subband 4, or only obtain the duplex type of subband 1 and subband 2. The duplex configuration can be UE-specific configuration information or cell-specific configuration information.

[0097] In a non-limiting embodiment, the first configuration information includes common configurations on multiple frequency domain resource units and dedicated configurations for target frequency domain resource units, and the dedicated configurations include full duplex.

[0098] Continue to refer to Figure 4 For subband 1 to subband 4, the general configuration is DDDU (indicating that the duplex types are downlink, downlink, downlink and uplink respectively). For subband 2 (target frequency domain resource unit), a dedicated configuration (D+U) can be configured.

[0099] Specifically, the network device may send a cell-specific high-level signaling to the terminal device, and the cell-specific high-level signaling includes the general configuration. The network device may send a device-specific high-level signaling to the terminal device, and the device-specific high-level signaling includes a dedicated configuration. Figure 4In the illustrated embodiment, the network device sends high-layer signaling to UE1, UE2, and UE3 respectively to inform them of the dedicated configuration of subband 2.

[0100] 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.

[0101] In this embodiment, frequency domain resource units with uplink and downlink duplex types are independently configured.

[0102] Please refer to Figure 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}.

[0103] Further, 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. Figure 5 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.

[0104] It should be noted that when the duplex type is full-duplex, the method for further distinguishing TDD and simultaneous same-frequency full-duplex can refer to the aforementioned method 1 and method 2, which will not be repeated here.

[0105] In a non-limiting embodiment, the first configuration information may be carried in a high-level signaling or a dynamic indication signaling, wherein the high-level signaling may specifically be an RRC signaling, a broadcast signaling, etc. The dynamic signaling may specifically be a DCI.

[0106] The above embodiments mainly describe the method of configuring the duplex type in the frequency domain. For the configuration of the duplex type in the time domain resources, one method is that the duplex type in the frequency domain resource unit can be applied to the entire time domain. Another method is to also configure the duplex type of the time domain resource unit.

[0107] In a specific embodiment, the duplex type of the time-frequency resource unit is configured by a first matrix and a second matrix. Each first element in the first matrix indicates that the duplex type is uplink or flexible, and each second element in the second matrix indicates that the duplex type is downlink or flexible, and 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 can be determined by scheduling information and / or some predefined transmission rules.

[0108] 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 limitation on this.

[0109] Further, 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. Wherein, the full-duplex can be simultaneous same-frequency full-duplex. 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 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.

[0110] See also Figure 6 The present application also discloses another communication method, which specifically includes the following steps:

[0111] Step 601: A network device sends a high-level signaling, wherein the high-level signaling includes at least one duplex configuration, wherein multiple resource units multiplex the at least one duplex configuration.

[0112] It should be pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.

[0113] It is understandable that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module.
