[0002] This application claims priority to Chinese Patent Application No. 201811302729.9, filed in China on November 2, 2018, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to the field of communication technology, and in particular to an information transmission method and communication device. Background Technology

[0004] In mobile communication systems, transmission channels or resources are associated with certain downlink signals, such as Channel State Information Reference Signal (CSI-RS) and Synchronization Signal and PBCH Block (SS / PBCH block), also known as SSB. Terminals can select appropriate resources for information transmission based on measurements of these downlink signals or instructions from network equipment.

[0005] In some cases, such as in unlicensed frequency band transmission mechanisms, the available resources for network devices and terminals are uncertain. Even if the network device configures certain downlink signal resources for the terminal, the terminal cannot determine whether the network device has preempted the corresponding resources and successfully transmitted the downlink signal. As shown in Figure 1, the network device only preempted two SSB resources in T1, transmitting SSB1 and SSB2; in T2, the network device did not preempt any resources; in T3, the network device preempted four SSB resources, transmitting SSB1, SSB2, SSB3, and SSB4. Among them, SSB1 and SSB3 are quasi-co-location (QCL), while SSB2 and SSB4 are QCL. The network device indicates that a total of SSB1, SSB3, and SSB4 were transmitted, and constructs the association between SSBs and transmission resources based on these four SSBs. Assuming the terminal receives SSB1 at T1, and doesn't enter T3 before attempting to transmit information after receiving SSB1, the terminal cannot measure SSB3. Therefore, the terminal can only select a transmission resource based on SSB1. If that transmission resource is unavailable, there are no other resources to choose from, potentially leading to transmission failure. In sidelinks, users may need to monitor resources to determine which are available, thus the availability of resources is also uncertain, and similar problems may arise.

[0006] Summary of the Invention

[0034] Please refer to Figure 1, which shows a block diagram of a wireless communication system applicable to embodiments of this disclosure. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 can also be referred to as a terminal device or user equipment (UE). The terminal 11 can be a terminal-side device such as a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), mobile internet device (MID), wearable device, or vehicle-mounted device. It should be noted that the specific type of terminal 11 is not limited in this disclosure embodiment. Network device 12 can be a Road Side Unit (RSU), a base station, or a core network. The base station can be a 5G or later version base station (e.g., gNB, 5G NR NB, etc.), or a base station in other communication systems (e.g., eNB, Wireless LAN (WLAN) access point, or other access point, etc.). The base station can be referred to as a node B, evolved node B, access point, base transceiver station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), B node, evolved B node (eNB), home B node, home evolved B node, WLAN access point, Wireless Fidelity (WiFi) node, or any other suitable term in the field, as long as the same technical effect is achieved. The base station is not limited to specific technical terms. It should be noted that in this embodiment of the disclosure, only a base station in an NR system is used as an example, but the specific type of base station is not limited.

[0035] The base station can communicate with terminal 11 under the control of a base station controller, which in various examples may be part of the core network or some base stations. Some base stations may communicate control information or user data with the core network via backhaul. In some examples, some of these base stations may communicate with each other directly or indirectly via backhaul links, which may be wired or wireless communication links. The wireless communication system may support operation on multiple carriers (waveform signals of different frequencies). A multi-carrier transmitter can transmit modulated signals on 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, etc.

[0036] The base station can wirelessly communicate with terminal 11 via one or more access point antennas. Each base station can provide communication coverage for its respective coverage area. The coverage area of ​​an access point can be divided into sectors that constitute only a part of that coverage area. The wireless communication system may include different types of base stations (e.g., macro base stations, micro base stations, or pico base stations). Base stations may also utilize different radio technologies, such as cellular or WLAN radio access technologies. 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 the same or different types of base stations, coverage areas using the same or different radio technologies, or coverage areas belonging to the same or different access networks) may overlap.

[0037] Communication links in a wireless communication system may include 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). UL transmissions may also be referred to as reverse link transmissions, and DL transmissions may also be referred to as forward link transmissions. Downlink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both. Similarly, uplink transmissions may be carried out using licensed frequency bands, unlicensed frequency bands, or both.

[0038] Figure 2 shows a block diagram of another wireless communication system applicable to this embodiment, namely a sidelink, also known as a secondary link, side link, or edge link transmission system. The wireless communication system includes a network device 21, a first terminal 22, and a second terminal 23. The first terminal 22 and the second terminal 23 can transmit directly without going through the network device. In this scenario, both the receiving end and the transmitting end are terminals; that is, the transmitting end's identity is different from that shown in Figure 1.

[0039] This disclosure provides an information transmission method applied to a receiving end. This method can be applied to an interaction system between a network device and a terminal, or to a side-link transmission system. When applied to the system shown in Figure 1, the receiving end is a terminal, and the sending end is a network device. When applied to the system shown in Figure 2, both the receiving end and the sending end are terminals.

[0040] As shown in Figure 3, this information transmission method includes the following steps:

[0041] Step 31: Obtain a reference object group containing at least two reference objects; wherein the reference objects contained in the reference object group are quasi-co-located.

[0042] A reference object group comprises multiple reference objects that satisfy a certain quasi-co-location relationship. The reference objects included in a reference object group may include, but are not limited to, SSBs and / or Channel State Information Reference Signals (CSI-RS). The signal types of the reference objects within a reference object group may be the same or different. For example, a reference object group may include quasi-co-located SSBs, or quasi-co-located CSI-RS, or both quasi-co-located SSBs and CSI-RS. Furthermore, the number of reference objects included in different reference object groups may be the same or different. Unless otherwise indicated that different reference object groups are quasi-co-located, the receiver does not assume quasi-co-location between multiple reference objects belonging to different reference object groups.

[0043] The reference objects included in the reference object group satisfy quasi-co-location relationships, also known as satisfying a certain beam relationship (e.g., using the same or corresponding beams), or satisfying a certain spatial relationship (e.g., the same or overlapping transmission directions), or having the same spatial domain transmission filter parameters (e.g., using the same spatial domain transmission filter, or using the same QCL reference (e.g., having the same QCL source), or having at least one QCL parameter or attribute. The QCL parameters or attributes include at least one of the following: Doppler spread, Doppler shift, average gain, average delay, delay spread, spatial Rx parameters, and when applicable. The quasi-co-location type satisfied by the reference objects included in the reference object group can be QCL Type A, QCL Type B, QCL Type C, and QCL... Any of Type D. It is worth noting that the embodiments in this disclosure are mainly illustrated using SSB as the reference object. When the reference object is CSI-RS or other signals, the corresponding implementation method can be referred to to achieve the expected effect.

[0044] Step 32: Transmit information according to the reference object group.

[0045] In this disclosure, the transmission mentioned in the embodiments can be either sending or receiving. The method of transmitting information according to a reference object group described in this disclosure can be applied to different transmission processes, such as various types of random access procedures, downlink control information (DCI) monitoring procedures, or other information transmission processes.

[0046] Step 31 can be implemented in different ways. This embodiment is only illustrated by the following method. Other possible implementation methods can also be applied to the embodiments of this disclosure.

[0047] Method 1: Obtain the parameter information (or related information) of the reference object group, and determine the reference object group based on the parameter information.

[0048] This method is an explicit indication method, and the parameter information of the reference object group includes at least one of the following: spatial domain information, pattern information, and index information of the reference object group. In addition to the above information, the parameter information may also include reference object group configuration information.

[0049] The reference object group can be indicated by airspace information (or direction information, QCL information, QCL type information, QCL airspace information, etc.), which can be predefined (such as by protocol agreement), indicated by network device, or pre-configured by manufacturer.

[0050] Taking SSB as an example, suppose the sending end (network device or terminal) sends SSB group configuration signaling to allocate the index information of 64 SSBs into 8 SSB index groups, i.e., dividing them into 8 SSB groups. Each group contains a maximum of 8 SSB indices. The receiving end (terminal) considers SSB indices within the same group to constitute an SSB group, and that this group is QCL (Quick Classification). Optionally, the sending end can also send spatial information for each SSB group. For example, the sending end sends a list of direction information for each SSB group {direction 2, direction 3, direction 4, direction 5, direction 7, direction 6, direction 8, direction 1}. Each direction identifier in the direction information list represents a different direction, and the direction identifiers in the direction information list correspond one-to-one with the SSB groups. Therefore, the receiving end can determine the transmission direction of each SSB group based on this spatial information.

[0051] Furthermore, reference object groups can also be indicated by pattern information and / or index information. The pattern information and index information can be predefined (e.g., according to protocol), indicated by the transmitter, or pre-configured by the manufacturer, and the indication methods for the pattern information and index information can be the same or different. In some embodiments, the index information of the reference object group may be implicitly carried or explicitly carried by certain signals, such as the Physical Broadcast Channel (PBCH), De-Modulation Reference Signal (DMRS), System Information Block (SIB), DCI, or other System Information (OSI). Optionally, the transmitter can also send spatial information for each reference object group, such as a direction information list {direction 2, direction 3} for each reference object group. Each direction identifier in the direction information list represents a different direction, and the direction identifiers in the direction information list correspond one-to-one with the reference object groups. Therefore, the receiver can determine the transmission direction of each reference object group based on this spatial information.

[0052] Taking SSB as an example, the receiving end obtains the SSB group pattern and SSB group index to determine the SSB group. For example: the protocol predefines the SSB group pattern, and in SSB group pattern configuration 1, SSB1 and SSB2 belong to one SSB group, while SSB3 and SSB4 belong to another SSB group. In SSB group pattern configuration 2, SSB1, SSB2, SSB3, and SSB4 belong to the same SSB group. The sending end indicates that the SSB group index = 1. At this time, the receiving end considers SSB1 and SSB2 to belong to one SSB group, which is QCL (Quickly Accepted Classes). SSB3 and SSB4 belong to another SSB group, which is QCL.

[0053] Furthermore, the index of an SSB group represents the spatial grouping factor (also known as the QCL factor, grouping factor, repetition factor, etc.), indicating the number of SSBs contained in an SSB group. For example, the range of the SSB group index is {1, 2, 4, 8}. When the SSB group index = 4, i.e., the spatial grouping factor = 4, it means that there are 4 QCL SSBs in an SSB group. Accordingly, the receiver can deduce the number of SSB groups based on the spatial grouping factor. For example, in certain frequency domains, the maximum number of SSBs transmitted in one period is L. If the spatial grouping factor = i, then there are L / i groups, and each group contains i QCL SSBs. The L / i QCL SSBs in each group may be L / i consecutive SSBs with consecutive indices, or they may be SSBs corresponding to indices that are discretely distributed according to a predetermined pattern. Alternatively, within a period, there can be at most L SSB time-domain locations. If the spatial grouping factor is i, then there are L / i groups, and each group contains i QCL SSB time-domain locations. These belong to the SSBs transmitted at the locations that are QCLs. The L / i QCL SSB time-domain locations within each group may be L / i consecutive time-domain locations with time-domain location numbers, or they may be time-domain locations discretely distributed according to a predetermined pattern.

[0054] Optionally, the index of an SSB group represents the number of groups, i.e., the number of SSB groups. For example, the range of the index of an SSB group is {1, 2, 4, 8}. When the index of an SSB group = 4, i.e., the number of SSB groups = 4, the receiver can deduce the number of SSBs within an SSB group based on the spatial grouping factor. In certain frequency domains, the maximum number of SSBs transmitted in one period is L. If the number of groups = j, then there are j groups, and each group contains L / j QCL SSBs. The L / j QCL SSBs in each group may be L / j SSBs with consecutive indices, or they may be SSBs corresponding to indices that are discretely distributed according to a predetermined pattern. Alternatively, the maximum number of SSB time-domain positions in one period is L. If the number of groups = j, then there are j groups, and each group contains L / j QCL SSB time-domain positions, where the SSBs transmitted at these time-domain positions are QCL. The time-domain locations of the SSBs of the L / j QCLs within each group may be L / j time-domain locations with consecutive time-domain location numbers, or they may be time-domain locations that are discretely distributed according to a predetermined pattern.

[0055] Method 2: Obtain the spatial information of at least two reference objects, and determine the reference object group based on the spatial information.

[0056] This method is an implicit indication method, wherein the spatial domain information of the reference object includes: spatial domain index information and / or spatial domain grouping factor, and the reference object is indicated by the reference index information and / or temporal domain location information. The reference index information and temporal domain location information of the reference object can be referred to as reference object indication information. It is worth noting that, in this embodiment, the temporal domain location information of the reference object can be a candidate temporal domain location of the reference object, or it can be the temporal domain location of the reference object that was actually used and transmitted.

[0057] The steps for determining the reference object group based on airspace information include:

[0058] 1. Identify reference objects with the same spatial index information as belonging to the same reference object group. Taking SSB as an example, the spatial information of an SSB is a set of spatial indexes (or QCL indices). The SSB indicates this through its SSB index; there is a one-to-one correspondence between the spatial indexes in the spatial index set and the SSB indexes. The receiver considers SSB indices corresponding to the same spatial index to belong to the same SSB group. Additionally, the SSB can also indicate this through its SSB temporal location information; there is a one-to-one correspondence between the spatial indexes in the spatial index set and the SSB temporal location information. The receiver considers SSB temporal location information corresponding to the same spatial index to belong to the same SSB group.

[0059] 2. Reference objects with the same modulo result of the spatial grouping factor belong to the same reference object group. Taking SSB as an example, the spatial grouping factor of SSB is a single value, such as M. SSB is indicated by the SSB index: spatial index = SSB index mod M. The receiver considers SSB indices with the same spatial index to belong to the same SSB group. In other words, the receiver considers SSBs with the same modulo result of the spatial grouping factor M to belong to the same SSB group. Alternatively, SSB can also be indicated by SSB time-domain location information: spatial index = SSB time-domain location information (such as SSB time-domain location index) mod M. The receiver considers SSB indices with the same spatial index to belong to the same SSB group. In other words, the receiver considers SSB time-domain transmission location information with the same modulo result of the spatial grouping factor M to belong to the same SSB group. It is worth noting that in this determination method, the number of reference object groups is M.

[0060] The parameter information of the reference object group, the spatial information of the reference object, and the reference object indication information (reference object index information and reference object temporal location information, etc.) can be carried in, but are not limited to, the following ways:

[0061] Explicitly carried: Explicitly carried in physical broadcast channels, control channels, system broadcast information blocks, or other Radio Resource Control (RRC) signaling, etc.

[0062] Predefined, manufacturer pre-configured, etc.;

[0063] Implicit carrying: For example, used in the generation of reference signal (RS) sequences, or in at least one of the signaling scrambling methods. The spatial information and reference object indication information of the reference object are determined by detecting the RS sequence or by descrambling. For example, the spatial information and reference object indication information of the reference object can be implicitly carried through the demodulated reference signal DMRS; the spatial information and reference object indication information of the reference object are used to generate the scrambling sequence of the PBCH, etc.

[0064] It is worth noting that the above-mentioned carrying method is an optional method. Different information mentioned in the embodiments of this disclosure (such as the spatial domain information of the reference object group, the index information of the reference object group, the spatial domain information of the reference object, the reference object indication information, etc.) can be carried in different ways, and this embodiment does not make specific limitations.

[0065] The following embodiments of this disclosure will further illustrate the method of information transmission based on a group of reference objects in different application scenarios.

[0066] Scene 1

[0067] Further, step 32 includes: determining subsequent available random access resources based on the first correspondence between the reference object group and the random access resources; and performing a random access procedure on the available random access resources.

[0068] In this embodiment of the disclosure, the random access procedure can be used for, but is not limited to, one of the following functions: contention-based random access, non-contention-based random access, System Information (SI) request, Beam Failure Recovery (BFR), and preambles for a specific group. The specific group includes at least one of group A and group B. This behavior refers to the terminal, after determining an available random access occasion (RO), attempting to acquire resources from an available RO and sending msg1 on the RO where resources were successfully acquired. If multiple available ROs are determined, the terminal can attempt to acquire resources from these ROs and send msg1 on one or more ROs where resources were successfully acquired. The terminal can send one or more msg1 messages. Specifically, the terminal can send multiple msg1 messages on one RO, send one msg1 message on multiple ROs, or send different msg1 messages on different ROs.

[0069] In the random access procedure mentioned in this disclosure, the first message sent by the terminal in the four-step random access process is message 1 (msg1), which is a preamble. In the two-step random access process, the first message sent by the terminal is message A (msgA), which may contain at least one of a preamble and data. The design of msg1 in various msg1-related schemes in this disclosure also applies to msgA.

[0070] It is worth noting that the random access procedure can determine the preamble, such as the 4-step random access procedure (4-RACH) or the 2-step random access procedure (2-RACH); the random access procedure may also not determine the preamble, such as the 2-step random access procedure that only sends data in msgA.

[0071] The first correspondence information includes at least one of the following:

[0072] The number of random access resources corresponding to the reference object group; such as the number of SSB groups corresponding to an RO, or the number of ROs corresponding to an SSB group.

[0073] The preamble information corresponding to the reference object group in the random access resource, wherein the preamble information is used to indicate at least one of: a preamble for contention-based random access, a preamble for non-contention-based random access, a preamble for System Information (SI) request, a preamble for Beam Failure Recovery (BFR), and a preamble for a specific group. For example, the preamble corresponding to each SSB group on each RO, in the form of a sequence index or sequence number, includes at least one of the following: a preamble for contention-based random access for each SSB group; a preamble for non-contention-based random access for each SSB group; a preamble for SI request for each SSB group; a preamble for BFR for each SSB group; a preamble for group A for each SSB group; a preamble for group B for each SSB group; power parameters of the random access resource; and measurement thresholds for the reference object group.

[0074] The power parameters of the random access resource; wherein the power parameters may include at least one of the following: the increment of the preamble power ramp counter, the preamble change, the preamble receive target power, and the preamble ramp step size.

[0075] The measurement threshold of the reference object group, for example, could be the average measurement threshold of the SSB group.

[0076] Scene 2

[0077] Step 31 includes: determining the target monitoring time based on the second correspondence information between reference object groups and monitoring times; and monitoring downlink information within the target monitoring time. The second correspondence information includes the number of monitoring times corresponding to each reference object group, used to indicate the number of monitoring times corresponding to each reference object group. Specifically, the second correspondence information indicates: the number of reference object groups corresponding to a set of monitoring times, a set of monitoring times containing at least one monitoring time, or the second correspondence information indicates the number of monitoring times corresponding to a reference object group. The correspondence between reference object groups and monitoring times can be one-to-one, one-to-many, or many-to-one.

[0078] Specifically, the monitoring activities include, but are not limited to:

[0079] Action 1: In the search space, monitor the monitoring timing corresponding to the first reference object, where the first reference object is a reference object quasi-co-addressable with the received Random Access Response (RAR) (or referred to as the reference object used for RAR reception), or, the first reference object is a reference object corresponding to the random access resource used to initiate the random access procedure. In the search space, the receiver assumes that the monitoring timing and the reference object used when receiving the RAR are QCLs.

[0080] Taking SSB as an example, in the search space, the monitoring time corresponding to the SSB used when monitoring and receiving RAR is monitored on the DCI. Assume that during the RACH process, the receiving end (terminal) determines that the next available RO is RO1 based on SSB1 and RO2 based on SSB2, and that RO1 and RO2 are different RO resources. The receiving end successfully obtains at least one of the resources RO1 and RO2 and sends a preamble on it. The sending end (network device) receives the preamble and feeds back the RAR. Assuming the terminal successfully receives the RAR using the QCL of SSB1, or if the terminal determines that the associated SSB of the RO resource corresponding to the RAR is SSB1 based on its Random Access Radio Network Temporary Identity (RA-RNTI), the terminal, in the search space of the control resource set, such as Common Resource set 0 (CORESET#0), specifically the Common Search Space (CSS), collects its own dedicated DCI (e.g., a DCI scrambled with the Cell Radio Network Temporary Identity (C-RNTI), and then monitors the DCI at the monitoring time corresponding to SSB1 in the CSS. Optionally, the terminal assumes that the monitoring time corresponding to SSB1 in the CSS and SSB1 are QCL. Note that the above example uses CORESET#0; this scheme also applies to other CORESETs, such as commonControlResourceSet and controlResourceSetZero.

[0081] Behavior 2: Within the search space, monitor the monitoring timing corresponding to the reference object group. Specifically, within the search space, the terminal assumes that the monitoring timing and the reference objects within the reference object group are QCLs (Quality Classes).

[0082] In the search space, DCI is listened to at monitoring times corresponding to the reference object group. Specifically, in the search space, DCI is listened to at all or part (i.e., at least one) of the monitoring times corresponding to the reference object group. Taking SSB as an example, in the search space, at least one of the monitoring times corresponding to the SSB group is monitored, where the terminal selects the monitoring time itself. Alternatively, in the search space, at least one SSB in the SSB group is selected, and the monitoring time corresponding to the selected at least one SSB is monitored, where the terminal can select the SSB whose measurement results meet certain threshold requirements based on the measurement results. Assume that during the RACH process, the terminal determines that the next available RO is RO1 based on SSB1 and RO2 based on SSB2, and RO1 and RO2 are different RO resources. The terminal successfully obtains at least one of the resources RO1 and RO2 and sends a preamble on it. The network device receives the preamble and feeds back RAR. When the terminal is controlling a resource set, such as the search space in CORESET#0, or collecting the user's dedicated DCI in the CSS, such as a C-RNTI scrambled DCI, it monitors the DCI at the monitoring times corresponding to SSB1 and SSB2 in the CSS. Optionally, the terminal assumes that the monitoring times corresponding to SSB1 and SSB2 in the CSS are QCL (Queries Classless) with both SSB1 and SSB2. Note that the above example uses CORESET#0; this scheme also applies to other CORESETs, such as commonControlResourceSet and controlResourceSetZero.

[0083] In this embodiment, the first and second correspondence information mentioned may be predefined, indicated by the network device, or pre-configured by the manufacturer, and the acquisition methods of different correspondence information may be different. This embodiment does not limit this.

[0084] Scene 3

[0085] Step 31 also includes: performing rate matching or puncturing on the target transmission information according to the reference object group, and transmitting the target transmission information after rate matching or puncturing.

[0086] The target transmission information differs from the reference objects included in the reference object group. Specifically, the step of rate matching or puncturing the target transmission information according to the reference object group includes: when the resources of at least one reference object in the reference object group at least partially overlap with the resources of the target transmission information, rate matching or puncturing the target transmission information is performed according to one of the following preset methods.

[0087] The resource overlap mentioned here includes: time-domain resource overlap, frequency-domain resource overlap, and overlap of both time-domain and frequency-domain resources. This embodiment specifically refers to time-frequency domain resource overlap. Cases where the resources of at least one reference object in the reference object group at least partially overlap with the resources of the target transmission information include, but are not limited to:

[0088] The resources of all reference objects within the reference object group completely or partially overlap with the resources of the target transmitted information.

[0089] The resources of some reference objects within the reference object group overlap with the resources of the target transmitted information.

[0090] The preset methods include: transmitting reference objects in the reference object group on the overlapping resources; or, transmitting target transmission information on the overlapping resources.

[0091] Specifically, the implementation methods for transmitting reference objects in a group of reference objects over overlapping resources include, but are not limited to:

[0092] 1. Overlapping resources are used for the transmission of reference objects, while target transmission information is transmitted on resources outside the time domain symbol where the overlapping resources are located.

[0093] 2. Overlapping resources are used for the transmission of reference objects, while target transmission information is transmitted on resources other than overlapping resources.

[0094] On the other hand, methods for transmitting target transmission information over overlapping resources include, but are not limited to:

[0095] 1. Overlapping resources are used for the transmission of target information, while reference objects corresponding to overlapping resources are transmitted on resources other than overlapping resources.

[0096] 2. Overlapping resources are used for the transmission of target information. The reference object corresponding to the overlapping resource is transmitted on a resource outside the time domain symbol where the overlapping resource is located.

[0097] 3. Overlapping resources are used for transmitting target information, while reference objects corresponding to overlapping resources are not transmitted.

[0098] 4. Overlapping resources are used for the transmission of target transmission information, and the reference signal group to which the reference object corresponding to the overlapping resource belongs is not transmitted.

[0099] It is worth noting that the term "determine" mentioned in the embodiments of this disclosure can also be called "select," and the two have the same meaning and are usually interchangeable. Reference objects satisfying certain quasi-co-addressable relationships in the embodiments of this disclosure have QCL transitivity. Taking the Discovery Reference Signal (DRS) as an example, a DRS may contain at least one of the following signals: SSB, CSI-RS, control signals, and data. The control signals may be at least one of the control signals used to schedule Remaining Minimum System Information (RMSI), Other System Information (OSI), paging messages, RAR, and msg4. The data signals may be at least one of RMSI, OSI, paging, RAR, and msg4. If at least one of the signals contained in one DRS and at least one of the signals contained in another DRS are QCL, then the other signals contained in these two DRSs are also quasi-co-addressable. If both DRSs contain SSBs and CSI-RSs, and the SSBs corresponding to the two DRSs are quasi-co-located, then the CSI-RSs corresponding to the two DRSs are also quasi-co-located. Optionally, the CSI-RS of one DRS and the SSB of the other DRS are also quasi-co-located, and vice versa. If both DRSs are quasi-co-located, then the SSBs corresponding to the two DRSs are quasi-co-located, and the corresponding CSI-RSs are also quasi-co-located. Optionally, the CSI-RS of one DRS and the SSB of the other DRS are also quasi-co-located.

[0133] The preset methods include: transmitting reference objects from a reference object group on overlapping resources; or transmitting target transmission information on overlapping resources. The reference objects include: Synchronization Signal Block (SSB) and / or Channel State Information Reference Signal (CSI-RS).

[0134] It is worth noting that the receiving communication device in this embodiment of the present disclosure can determine the available transmission resources based on a reference object group containing at least two reference objects, which can increase the selection opportunities of available transmission resources and thereby improve the transmission efficiency of information.

[0135] The above embodiments describe the information transmission method of this disclosure from the receiving end perspective. The following embodiments will further describe the information transmission method from the sending end perspective with reference to the accompanying drawings.

[0136] As shown in Figure 5, the information transmission method of this disclosure embodiment, applied at the sending end, includes the following steps:

[0137] Step 51: Send parameter information of a reference object group containing at least two reference objects to the receiving end, wherein the reference objects contained in the reference object group are quasi-co-located, and the parameter information includes at least one of the following: spatial domain information, pattern information and index information of the reference object group.

[0138] A reference object group comprises multiple reference objects that satisfy a certain quasi-co-addressing relationship. The reference objects included in a reference object group may include, but are not limited to, SSBs and / or Channel State Information Reference Signals (CSI-RS). The signal types of the reference objects within a reference object group may be the same or different. For example, a reference object group may include quasi-co-addressable SSBs, or quasi-co-addressable CSI-RS, or both quasi-co-addressable SSBs and CSI-RS. Furthermore, the number of reference objects included in different reference object groups may be the same or different. Unless otherwise indicated that different reference object groups are quasi-co-addressable, the receiver does not assume quasi-co-addressability between multiple reference objects belonging to different reference object groups.

[0139] The reference object group can be indicated by spatial information (also called direction information, QCL information, QCL type information, QCL spatial information, etc.), which can be predefined (e.g., protocol-defined), indicated by the network device, or pre-configured by the manufacturer. Furthermore, the reference object group can also be indicated by pattern information and / or index information, which can also be predefined (e.g., protocol-defined), indicated by the network device, or pre-configured by the manufacturer, and the indication methods of pattern information and index information can be the same or different. In some embodiments, the index information of the reference object group may be implicitly carried by certain signals, such as PBCH, DMRS, SIB, DCI, or other system information, or explicitly carried by these signals. Optionally, the network device can also send spatial information for each reference object group, for example, sending a direction information list {direction 2, direction 3} for each reference object group. Each direction identifier in the direction information list represents a different direction, and the direction identifiers in the direction information list correspond one-to-one with the reference object group. Therefore, the terminal can determine the transmission direction of each reference object group based on this spatial information.

[0140] It is worth noting that step 51 corresponds to method one of determining the reference object group in the receiving end embodiment, so it will not be described again here.

[0141] Furthermore, in addition to indicating the reference object group using step 51, before step 51, the transmitting end further includes: sending spatial domain information of at least two reference objects to the receiving end, wherein the spatial domain information includes: spatial domain index information and / or spatial domain grouping factor, and the reference objects are indicated by the reference index information and / or temporal location information. It is worth noting that in this embodiment, the temporal location information of the reference objects can be the candidate temporal location of the reference objects, or the actual temporal location where the reference objects were sent. Thus, the receiving end can determine the reference object group based on the spatial domain information of the reference objects. Specifically, the receiving end can determine that reference objects with the same spatial domain index information belong to the same reference object group. Alternatively, it can determine that reference objects with the same modulo result of the spatial domain grouping factor belong to the same reference object group. This method is an implicit indication of the reference object group by the transmitting end, corresponding to the second method of determining the reference object group in the receiving end embodiment, and therefore will not be elaborated further here.

[0142] Furthermore, before or after step 51, at least one of the following is also included:

[0143] Send the first correspondence between the reference object group and the random access resources to the receiving end;

[0144] Send the second correspondence information between the reference object group and the monitoring time to the receiving end.

[0145] The first correspondence information includes at least one of the following:

[0146] Information on the number of random access resources corresponding to the reference object group;

[0147] The preamble information corresponding to the reference object group in the random access resource, wherein the preamble information is used to indicate at least one of the following: a preamble for contention-based random access, a preamble for non-contention-based random access, a preamble for System Information (SI) request, a preamble for Beam Failure Recovery (BFR), and a preamble for a specific group;

[0148] Power parameters of random access resources;

[0149] Measurement thresholds for the reference object group.

[0150] The second correspondence information includes: the number of monitoring times corresponding to the reference object group.

[0151] The specific implementations of the first and second correspondence information can be found in the receiving end embodiment, and will not be repeated here. Furthermore, the sending end embodiment in this disclosure corresponds to the receiving end embodiment. Those skilled in the art should understand that the above-mentioned receiving end embodiments can all be transformed into sending end embodiments through interactive correspondence, and therefore will not be repeated here.

[0152] In the information transmission method of this disclosure embodiment, the sending end communication device sends a reference object group containing at least two reference objects that satisfy a quasi-co-address relationship to the receiving end, so that the receiving end can determine the available transmission resources based on the reference object group containing at least two reference objects, thereby increasing the selection opportunities of available transmission resources and improving the information transmission efficiency.

[0153] The above embodiments illustrate information transmission methods in different scenarios. The communication devices of the corresponding sending end will be further described below with reference to the accompanying drawings.

[0154] As shown in Figure 6, the communication device 600 of this embodiment can transmit parameter information of a reference object group containing at least two reference objects to the receiving end in the above embodiment. The reference objects included in the reference object group are quasi-co-located. The parameter information includes details of at least one of the following methods: spatial domain information, pattern information, and index information of the reference object group, achieving the same effect. Specifically, the communication device 600 includes the following functional modules:

[0155] The first transmitting module 610 is used to transmit parameter information of a reference object group containing at least two reference objects to the receiving end, wherein the reference objects contained in the reference object group are quasi-co-located, and the parameter information includes at least one of the following: spatial domain information, pattern information, and index information of the reference object group.

[0156] The communication equipment 600 also includes:

[0157] The second transmitting module is used to transmit spatial information of at least two reference objects to the receiving end. The spatial information includes spatial index information and / or spatial grouping factor, and the reference objects are indicated by reference index information and / or time-domain location information.

[0158] The communication module 600 further includes at least one of the following:

[0159] The third sending module is used to send the first correspondence between the reference object group and the random access resources to the receiving end;

[0160] The fourth sending module is used to send the second correspondence information between the reference object group and the monitoring time to the receiving end.

[0161] The first correspondence information includes at least one of the following:

[0162] Information on the number of random access resources corresponding to the reference object group;

[0163] The preamble information corresponding to the reference object group in the random access resource, wherein the preamble information is used to indicate at least one of the following: a preamble for contention-based random access, a preamble for non-contention-based random access, a preamble for System Information (SI) request, a preamble for Beam Failure Recovery (BFR), and a preamble for a specific group;

[0164] Power parameters of random access resources;

[0165] Measurement thresholds for the reference object group.

[0166] The second correspondence information includes the number of monitoring opportunities corresponding to the reference object group. The reference objects include: Synchronization Signal Block (SSB) and / or Channel State Information Reference Signal (CSI-RS).

[0167] It is worth noting that the transmitting communication device in this embodiment sends a reference object group containing at least two reference objects that satisfy a quasi-co-address relationship to the receiving end, so that the receiving end can determine the available transmission resources based on the reference object group containing at least two reference objects, thereby increasing the selection opportunities of available transmission resources and improving the transmission efficiency of information.

[0168] It should be noted that the division of the various modules in the communication equipment of the receiving and transmitting ends described above is merely a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, these modules can be implemented entirely in software through processing element calls; they can be fully implemented in hardware; or some modules can be implemented by processing element calls to software, while others are implemented in hardware. For example, a determination module can be a separate processing element, or it can be integrated into a chip in the aforementioned device. Alternatively, it can be stored as program code in the memory of the aforementioned device, and its function can be called and executed by a processing element of the aforementioned device. The implementation of other modules is similar. Moreover, these modules can be fully or partially integrated together, or they can be implemented independently. The processing element mentioned here can be an integrated circuit with signal processing capabilities. In the implementation process, each step of the above method or each of the above modules can be completed through integrated logic circuits in the hardware of the processor element or through software instructions.

[0169] For example, these modules can be one or more integrated circuits configured to implement the above methods, such as one or more Application Specific Integrated Circuits (ASICs), one or more digital signal processors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs). As another example, when a module is implemented using processing element scheduler code, the processing element can be a general-purpose processor, such as a Central Processing Unit (CPU) or other processor capable of calling program code. Furthermore, these modules can be integrated together to implement a system-on-a-chip (SOC).

[0170] To better achieve the above objectives, Figure 7 is a schematic diagram of the hardware structure of a terminal implementing various embodiments of this disclosure. The terminal 70 includes, but is not limited to, components such as: a radio frequency unit 71, a network module 72, an audio output unit 73, an input unit 74, a sensor 75, a display unit 76, a user input unit 77, an interface unit 78, a memory 79, a processor 710, and a power supply 711.

A terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements. In the embodiments of this disclosure, the terminal includes, but is not limited to, mobile phones, tablet computers, laptop computers, PDAs, in-vehicle terminals, wearable devices, and pedometers.

[0171] This terminal can be used as a receiver or a transmitter.

[0172] When the terminal is used as a receiver, the radio frequency unit 71 is used to acquire a reference object group containing at least two reference objects; wherein the reference objects contained in the reference object group are quasi-co-located.

[0173] Processor 710 is used for information transmission based on a reference object group.

[0174] When the terminal acts as the receiving end, it can determine the available transmission resources based on a reference object group containing at least two reference objects, which can increase the selection opportunities of available transmission resources and thus improve the efficiency of information transmission.

[0175] When the terminal is used as a transmitter, the radio frequency unit 71 is used to: send parameter information of a reference object group containing at least two reference objects to the receiver, wherein the reference objects contained in the reference object group are quasi-co-located, and the parameter information includes at least one of the following: spatial domain information, pattern information, and index information of the reference object group.

[0176] When the terminal acts as the sender, it can send a reference object group containing at least two reference objects that satisfy a quasi-co-address relationship to the receiver. This allows the receiver to determine available transmission resources based on the reference object group containing at least two reference objects, increasing the selection opportunities for available transmission resources and thus improving the efficiency of information transmission.

[0177] It should be understood that, in this embodiment of the disclosure, the radio frequency unit 71 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink data from the base station and processes it with the processor 710; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 71 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc. Furthermore, the radio frequency unit 71 can also communicate with networks and other devices through a wireless communication system.

[0179] The audio output unit 73 can convert audio data received by the radio frequency unit 71 or the network module 72 or stored in the memory 79 into audio signals and output them as sound. Furthermore, the audio output unit 73 can also provide audio output related to specific functions performed by the terminal 70 (e.g., call signal reception sound, message reception sound, etc.). The audio output unit 73 includes a speaker, a buzzer, and a receiver, etc.

[0180] Input unit 74 is used to receive audio or video signals. Input unit 74 may include a graphics processing unit (GPU) 741 and a microphone 742. The GPU 741 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on display unit 76. The image frames processed by GPU 741 can be stored in memory 79 (or other storage medium) or transmitted via radio frequency unit 71 or network module 72.

The ambient light sensor can adjust the brightness of the display panel 761 according to the ambient light level, and the proximity sensor can turn off the display panel 761 and / or backlight when the terminal 70 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes). When stationary, it can detect the magnitude and direction of gravity and can be used to identify the terminal's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Sensor 75 may also include fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., which will not be described in detail here.

Specifically, user input unit 77 includes a touch panel 771 and other input devices 772. Touch panel 771, also known as a touch screen, can collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 771). Touch panel 771 may include two parts: a touch detection device and a touch controller. The touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 710, which receives and executes commands from the processor 710. In addition, touch panel 771 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. Besides touch panel 771, user input unit 77 may also include other input devices 772. Specifically, other input devices 772 may include, but are not limited to, physical keyboards, function keys (such as volume control buttons, power buttons, etc.), trackballs, mice, joysticks, etc., which will not be described in detail here.

[0184] Furthermore, the touch panel 771 can cover the display panel 761. When the touch panel 771 detects a touch operation on or near it, it transmits the information to the processor 710 to determine the type of touch event. Subsequently, the processor 710 provides corresponding visual output on the display panel 761 according to the type of touch event. Although in Figure 7, the touch panel 771 and the display panel 761 are shown as two separate components to implement the input and output functions of the terminal, in some embodiments, the touch panel 771 and the display panel 761 can be integrated to implement the input and output functions of the terminal. Specific details are not limited here.

[0187] The processor 710 is the control center of the terminal, connecting various parts of the terminal through various interfaces and lines. It performs various functions and processes data by running or executing software programs and / or modules stored in the memory 79, and by calling data stored in the memory 79, thereby providing overall monitoring of the terminal. The processor 710 may include one or more processing units; optionally, the processor 710 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may also not be integrated into the processor 710.

When executed by the processor 710, this computer program implements the various processes of the above-described information transmission method embodiments and achieves the same technical effects; therefore, to avoid repetition, it will not be described again here. The terminal can be a wireless terminal or a wired terminal. A wireless terminal can be a device that provides voice and / or other service data connectivity to a user, such as a handheld device with wireless connectivity or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone), and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device. These exchange voice and / or data with the radio access network. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminals can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, remote terminals, access terminals, user terminals, user agents, and user devices or user equipment; no specific terminology is used here.
