Title: Wireless communication method and apparatus and communication system

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is a continuation application of International Patent Application PCT/CN2019/109212 filed on Sep. 29, 2019, the entire contents of which are incorporated herein by reference. 
    
    
     FIELD 
     This disclosure relates to the field of communications. 
     BACKGROUND 
     Currently, an NR (New Radio) system only supports initiating a beam failure recovery procedure on a primary cell (PCell) or a primary and secondary cell (PSCell). If a beam failure occurs on the secondary cell (SCell), the terminal equipment cannot notify the network device to make corresponding adjustments in time. However, since the SCell may carry a large amount of data services, the lack of beam failure resolution for SCell will cause a sharp drop in system performance. Therefore, it is necessary to introduce a mechanism for solving the SCell beam failure, that is, the SCell beam failure procedure. 
     In addition, the NR system will be further enhanced to enable simultaneous transmission of different types of services. In order to avoid conflicts between different services, a very important method is to indicate corresponding priorities to signals, that is, behaviors of a terminal equipment when two signals collide may be judged according to priorities to which corresponding signals correspond. 
     It should be noted that the above description of the background ais merely provided for clear and complete explanation of this disclosure and for easy understanding by those skilled in the art. And it should not be understood that the above technical solution is known to those skilled in the art as it is described in the background of this disclosure. 
     SUMMARY 
     It was found by the inventors that in a process of SCell beam failure recovery, a terminal equipment may transmit corresponding information of the SCell beam failure to the network device by using an uplink signal. However, there is no corresponding mechanism to determine a priority of the uplink signal, which will result in that when resources of the uplink signal collides with resources of other uplink signals, whether the signal is able to be transmitted is unable to be determined, thereby resulting in low efficiency of the system.

     In the embodiments of this disclosure, the term “network device”, for example, refers to a device in a communication system that accesses a terminal equipment to the communication network and provides services for the terminal equipment. The network device may include but not limited to the following equipment: a base station (BS), an access point (AP), a transmission reception point (TRP), a broadcast transmitter, a mobile management entity (MME), a gateway, a server, a radio network controller (RNC), a base station controller (BSC), etc. 
     The base station may include but not limited to a node B (NodeB or NB), an evolved node B (eNodeB or eNB), and a 5G base station (gNB), etc. Furthermore, it may include a remote radio head (RRH), a remote radio unit (RRU), a relay, or a low-power node (such as a femto, and a pico, etc.). The term “base station” may include some or all of its functions, and each base station may provide communication coverage for a specific geographical area. And a term “cell” may refer to a base station and/or its coverage area, which may be expressed as a serving cell, and may be a macro cell or a pico cell, depending on a context of the term. 
     In the embodiments of this disclosure, the term “user equipment (UE)” refers to, for example, an equipment accessing to a communication network and receiving network services via a network device, and may also be referred to as a “terminal equipment (TE)”. The terminal equipment may be fixed or mobile, and may also be referred to as a mobile station (MS), a terminal, a subscriber station (SS), an access terminal (AT), or a station, etc. 
     The terminal equipment may include but not limited to the following devices: a cellular phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a hand-held device, a machine-type communication device, a lap-top, a cordless telephone, a smart cell phone, a smart watch, and a digital camera, etc. 
     For another example, in a scenario of the Internet of Things (IoT), etc., the user equipment may also be a machine or a device performing monitoring or measurement. For example, it may include but not limited to a machine-type communication (MTC) terminal, a vehicle mounted communication terminal, a device to device (D2D) terminal, and a machine to machine (M2M) terminal, etc. 
     In this embodiment of this disclosure, regarding an uplink signal used for beam failure recovery (BFR), such as a PUCCH for beam failure recovery, the terminal equipment performs beam failure detection on an SCell, such as performing beam failure detection according to a configured reference signal (RS) or a specific downlink signal (PDCCH). If a beam failure occurs in at least one of related SCells, the terminal equipment may transmit an uplink signal (PUCCH) on a PCell. A format of the uplink signal may be format 0 or format 1, and the uplink signal includes 1-bit information, which is used to notify the network device of whether BFR occurs in a related BFR SCell. 
     In the embodiments of this disclosure, regarding DL SPSs, one DL SPS generally corresponds to one SPS configuration, and downlink semi-persistent scheduling activation control information (DL SPS activation PDCCH) refers to control information for activating one SPS configuration set. For example, the SPS configuration set has a specific ID or has no specific ID, and the SPS configuration set includes one or more than one SPS configuration. Here, one SPS configuration being activated is taken as an example. As shown in  FIG. 1 , when a UE receives the activation PDCCH (DCI), the DCI and a corresponding SPS configuration may provide information for receiving a corresponding PDSCH (physical downlink shared channel). As shown in  FIG. 1 , according to the information, the UE receives a first PDSCH after activation (at a slot n). Thereafter, the UE may determine a receiving position of a second PDSCH according to a period in the SPS configuration (for example, the period is P), that is, a slot n+P, and receive subsequent PDSCHs, and so on. When the UE receives downlink semi-persistent scheduling release/deactivation control information (DL SPS release/deactivation PDCCH), it stops receiving a PDSCH to which a corresponding SPS configuration corresponds, or, in other words, clears corresponding downlink assignment and releases corresponding configurations. In addition, that an activation PDCCH (activation DCI) activates an SPS configuration set may be understood as that all SPS configurations in the SPS configuration set are activated or reactivated and conform to the above description of behaviors. That a release or deactivation PDCCH (release or deactivation DCI) releases or deactivates an SPS configuration set may be understood as that all SPS configurations in the SPS configuration set are deactivated or released (if corresponding SPS configurations are active) and conform to the above description of behaviors. 
     In the embodiments of this disclosure, regarding UL Grant Type 2, one UL Grant Type 2 uplink transmission generally corresponds to one CG configuration, and a UL Grant Type 2 activation PDCCH refers to control information used to activate a CG configuration set, for example, the CG configuration set has a specific ID or has no specific ID. The CG configuration set contains one or more than one CG configurations. Here, taking one of the CG configurations as an example, as shown in  FIG. 2 , when the UE receives the activation PDCCH (DCI), the DCI and a corresponding CG configuration may provide information for transmitting a corresponding PUSCH (physical uplink shared channel). As shown in  FIG. 2 , according to the information, the UE transmits a first PUSCH after activation (at a slot n). Thereafter, the UE may determine a transmitting position of a second PUSCH according to a period in the CG configuration (for example, the period is P), that is, a slot n+P, and transmit subsequent PUSCHs, and so on. When the UE receives the downlink semi-persistent scheduling release/deactivation control information (DL SPS release/deactivation PDCCH), it stops transmitting a PUSCH to which a corresponding CG configuration corresponds, or, in other words, clears corresponding UL grants and releases corresponding configurations. In addition, that an activation PDCCH (activation DCI) activates a CG configuration se may be understood as that all CG configurations in the CG configuration set are activated or reactivated and conform to the above description of behaviors. That a release or deactivation PDCCH (release or deactivation DCI) releases or deactivates an CG configuration set may be understood as that all CG configurations in the CG configuration set are released or deactivated (if corresponding CG configurations are active) and conform to the above description of behaviors. 
     In  FIGS. 1 and 2  and corresponding description, a slot is taken as a time unit; however, this disclosure is not limited thereto, and a time unit involved in this disclosure may also be a symbol, a sub-slot, or a frame, or a sub-frame, etc. 
     Various implementations of the embodiments of this disclosure shall be described below with reference to the accompanying drawings. These implementations are illustrative only, and are not intended to limit this disclosure. 
     Embodiment of the First Aspect 
     The embodiment of the first aspect of this disclosure provides a wireless communication method, applicable to a terminal equipment.  FIG. 3  is a schematic diagram of the wireless communication method of the embodiment of this disclosure. Referring to  FIG. 3 , the method includes: 
     operation  301 : a terminal equipment receives an indication information set; and 
     operation  301 : the terminal equipment determines a priority of a first uplink signal according to the indication information set, the first uplink signal being an uplink signal used for beam failure recovery (BFR). 
     Currently, there is no mechanism for indicating a priority of an uplink signal related to a BFR procedure. The priority of the uplink signal being determined according to the method of the embodiment of this disclosure may better solve a problem of signal conflict, so that the system is able to deal with a transmission relationship between the uplink signal and other uplink signals, thereby improving the efficiency of the system. 
     In the embodiment of this disclosure, the above beam failure recovery may refer to beam failure recovery related to an SCell, and may also refer to beam failure recovery related to an SpCell; however, this disclosure is not limited thereto. 
     In the embodiment of this disclosure, the above first uplink signal may be a PUCCH (physical uplink control channel), and a format of the PUCCH may be format 0 or format 1 or other formats. In addition, the above first uplink signal may also be a PUSCH (physical uplink shared channel) or a PRACH (physical random access channel), and this disclosure is not limited thereto. 
     In the embodiment of this disclosure, the indication information in the above indication information set may act on at least one cell corresponding to the above first uplink signal, and here, the cell corresponding to the above first uplink signal may be a cell corresponding to a BFR configuration or process to which the above first uplink signal corresponds. For example, the cell may be an SCell or a SpCell, and the cell may belong to the same cell group as the above first uplink signal, and this disclosure is not limited thereto. Since the above first uplink signal is associated with the above cell, the indication information acting on the above cell may help the terminal equipment to determine the priority of the first uplink signal. In addition, it may also be understood that if the indication information does not act on the cell, it is irrelevant to the priority of the first uplink signal. Thus, the terminal equipment may determine the priority of the first uplink signal according to associated indication information. 
     In the embodiment of this disclosure, the indication information in the above indication information set may act on an activated bandwidth part (BWP). As the above first uplink signal is associated with the above BWP, the indication information acting on the above BWP may help the terminal equipment to determine the priority of the first uplink signal. In addition, it may also be understood that if the indication information does not act on the above BWP, it is irrelevant to the priority of the first uplink signal. Thus, the terminal equipment may determine the priority of the first uplink signal according to associated indication information. 
     In an embodiment, the above indication information set includes at least first indication information, the first indication information being used to indicate the priority of the above first uplink signal. Thus, the terminal equipment may directly determine the priority of the first uplink signal according to the first indication information. In this example, the first indication information may be RRC signaling; however, this disclosure is not limited thereto. 
     In another embodiment, the above indication information set at least includes second indication information, the second indication information being used to indicate a priority of a BFR procedure and/or configuration to which the first uplink signal corresponds. Thus, the terminal equipment may indirectly determine the priority of the first uplink signal according to the second indication information. In this example, the second indication information may be RRC signaling; however, this disclosure is not limited thereto. 
     In a further embodiment, the above indication information set at least includes third indication information, the third indication information being used to indicate or determine at least one of the following three items: a priority to which activated SPS PDSCH reception corresponds; a priority to which activated CG PUSCH transmission corresponds; and a priority associated with downlink control information (DCI). Thus, the terminal equipment may indirectly determine the priority of the first uplink signal according to the third indication information. For example, the terminal equipment may determine the priority of the first uplink signal according to a highest priority in priorities to which the third indication information corresponds. 
     In the embodiment of this disclosure, the priority to which the activated SPS PDSCH reception corresponds refers to a priority corresponding to an SPS configuration to which the activated SPS PDSCH reception corresponds. Here, the SPS PDSCH reception refers to that the terminal equipment monitors or receives a corresponding PDSCH according to SPS activation DCI and corresponding SPS configuration information (at an active BWP in a corresponding serving cell). Here, the SPS activation DCI (i.e. DCI used for activating the SPS) refers to, with respect to a corresponding SPS configuration, SPS activation DCI most close (to its corresponding SPS PDSCH reception) in the time domain, that is, there exists no other SPS active DCI (belonging to the same SPS configuration) between the SPS activation DCI and its corresponding SPS PDSCH reception. 
     In at least one embodiment, if there exists an activated DL SPS, the terminal equipment may determine the priority of the first uplink signal at least according to a priority to which the activated SPS PDSCH reception corresponds. For example, if a corresponding priority is configured or is indicated via the activation DCI, the priority of the first uplink signal may be determined according to the configuration or the indication. For another example, if a corresponding priority is not configured or is not indicated via the activation DCI, the priority of the first uplink signal may be determined according to a default or predefined priority. 
     In the embodiment of this disclosure, the priority to which activated CG PUSCH transmission corresponds refers to a priority corresponding to a CG configuration to which the activated CG PUSCH transmission corresponds. The CG PUSCH transmission refers to that the terminal equipment transmits a corresponding PUSCH according to the CG activation DCI and corresponding CG configuration information (at an active BWP in a corresponding serving cell). Here, the CG activation DCI (that is, DCI used for activating a CG) refers to, with respect to a corresponding CG configuration, CG activation DCI most close (to its corresponding CG PUSCH transmission) in the time domain, that is, there exists no other CG activation DCI (belonging to the same CG configuration) between the CG activation DCI and its corresponding CG PUSCH transmission. 
     In at least one embodiment, if there exists an activated UL CG, the terminal equipment may determine the priority of the first uplink signal at least according to a priority to which the activated CG PUSCH transmission corresponds. For example, if a corresponding priority is configured or is indicated via the activation DCI, the priority of the first uplink signal may be determined according to the configuration or the indication. For another example, if a corresponding priority is not configured or is not indicated via the activation DCI, the priority of the first uplink signal may be determined according to a default or predefined priority. 
     In this embodiment of this disclosure, the priority associated with the above downlink control information (DCI) may be one of the following: a highest priority indicated (or is able to be indicated) by a field of the DCI used for indicating priorities, a highest priority to which a scrambling ID corresponds, the scrambling ID scrambling CRS to which the DCI corresponds, a highest priority to which a CORESET (control resource set) corresponds, an SS (search space) monitoring the DCI corresponding to the CORESET, and a priority to which a format of the DCI corresponds. 
     For example, the DCI includes a field for indicating a priority, and a size of the field is 1, then the DCI may indicate at most two priorities. Assuming that codepoint ‘0’ corresponds to a first priority, codepoint ‘1’ corresponds to a second priority, and the first priority is higher than the second priority, a highest priority associated with the DCI is (may also be referred to as a highest priority that the DCI is allowed to indicate, same as below) is the first priority. 
     For another example, CRC to which the DCI corresponds may be scrambled by two scrambling IDs, namely ID #1 and ID #2, then the DCI may indicate at most two priorities. Assuming that ID #1 corresponds to a first priority, ID #2 corresponds to a second priority, and the first priority is higher than the second priority, a highest priority associated with the DCI is the first priority. 
     For a further example, the DCI may be monitored by two SSs corresponding to different CORESETs, namely CORESET #1 and CORESET #2, then the DCI may indicate at most two priorities. Assuming that CORESET #1 corresponds to a first priority, CORESET #2 corresponds to a second priority, and the first priority is higher than the second priority, a highest priority associated with the DCI is the first priority. 
     For still another example, DCI formats 0_0/0_1/1_0/1_1 correspond to a first priority, DCI format A corresponds to a second priority, and the second priority is higher than the first priority, then a highest priority associated with the DCI is the second priority. 
     For yet another example, if the DCI may only indicate one priority, DCI formats 0_0/0_1/1_0/1_1 correspond to a first priority; and if DCI may only indicate one priority, DCI format A corresponds to a second priority, and the second priority is higher than the first priority, then a highest priority associated with the DCI is the second priority. 
     For yet still another example, if DCI may only indicate one priority, DCI formats 0_0/0_1/1_0/1_1 correspond to a first priority, DCI format A corresponds to a second priority, and the second priority is higher than the first priority, then a highest priority associated with the DCI is the second priority. 
     For a yet further example, if DCI formats 0_0/0_1/1_0/1_1 correspond to a first priority and the DCI may only indicate one priority, DCI format A corresponds to a second priority, and the second priority is higher than the first priority, then a highest priority associated with the DCI is the second priority. 
     In the above examples, that “the DCI may only indicate one priority” refers to that the DCI does not have a field for indicating a priority, or the DCI does not distinguish priorities by using the scrambling RNTI corresponding to the CRC, or the DCI does not distinguish priorities by using the CORESET corresponding to the corresponding search space (SS). 
     In the above examples, the “DCI format A” refers to at least one satisfying the following descriptions that: 
     a length of an HPN (HARQ process number, hybrid automatic repeat request process number) field of the DCI format is configurable; 
     a length of an RV (redundancy version) field of the DCI format is configurable; and 
     a format of the DCI is DCI format 0_2, or a format of the DCI is DCI format 1_2. 
     In the embodiment of this disclosure, the above downlink control information refers to monitored downlink control information, such as monitored DCI, or monitored PDCCH, etc. Here, “monitored” may be monitored by a terminal equipment; however, this disclosure is not limited thereto. 
     In this embodiment of this disclosure, after the priority of the first uplink signal is determined, when resources used for transmitting the first uplink signal overlap with resources used for transmitting another uplink signal (referred to as a second uplink signal), transmission of the uplink signals may be performed according to the priority of the first uplink signal and a priority of the second uplink signal. Here, “overlap” refers to overall overlapping (in the time domain) or partial overlapping (in the time domain), and it may also be understood that at least one symbol or slot or sub-slot of the first uplink signal overlaps with at least one symbol or slot or sub-slot of the second uplink signal. 
     In at least one embodiment, if the resources used for transmitting the first uplink signal overlap with the resources used for transmitting the second uplink signal and the priority of the first uplink signal is higher than the priority of the second uplink signal, the terminal equipment may transmit the first uplink signal. 
     In at least one embodiment, if the resources used for transmitting the first uplink signal overlap with the resources used for transmitting the second uplink signal, and the priority of the first uplink signal is lower than the priority of the second uplink signal, the terminal equipment may transmit the second uplink signal. 
     In at least one embodiment, if the resources used for transmitting the first uplink signal overlap with the resources used for transmitting the second uplink signal and the priority of the first uplink signal is identical to the priority of the second uplink signal, the terminal equipment may transmit the first uplink signal. 
     In this embodiment, the second uplink signal may be, for example, a physical uplink control channel (PUCCH) at least carrying scheduling request (SR) information, or, a physical uplink control channel (PUCCH) at least carrying channel state information (CSI), or, a PUCCH at least carrying hybrid automatic repeat request feedback (HARQ-ACK) information, or, a physical uplink shared channel (PUSCH). 
     In at least one embodiment, if the resources used for transmitting the first uplink signal overlap with the resources used for transmitting the second uplink signal and the priority of the first uplink signal is identical to the priority of the second uplink signal, the terminal equipment may transmit the second uplink signal. 
     In this embodiment, the second uplink signal may be, for example, a PUSCH, and the PUSCH includes information carried by the first uplink signal. 
     In at least one embodiment, if the resources used for transmitting the first uplink signal overlap with the resources used for transmitting the second uplink signal and the priority of the first uplink signal is identical the priority of the second uplink signal, the terminal equipment may transmit the third uplink signal, wherein information carried by the third uplink signal includes the information carried by the first uplink signal and information carried by the second uplink signal. 
     In this example, the second uplink signal may be a PUCCH, the third uplink signal may be a PUCCH, and the second uplink signal may include an HARQ (hybrid automatic repeat request) and/or CSI (channel state information). 
     According to the method of the embodiment of this disclosure, the terminal equipment is able to process the uplink transmission of identical or different priorities, thereby avoiding ambiguities of behaviors and improving the system efficiency. 
     Embodiment of the Second Aspect 
     The embodiment of the second aspect of this disclosure provides a wireless communication method, applicable to a terminal equipment. What is different from the wireless communication method in the first aspect is that in the embodiment of this disclosure, the priority of the first uplink signal is predefined. Contents identical to those in the embodiment of the first aspect shall not be described herein any further. 
       FIG. 4  is a schematic diagram of the wireless communication method of the embodiment of this disclosure. As shown in  FIG. 4 , the method includes: 
     operation  401 : a terminal equipment determines a priority of a first uplink signal according to a predefined priority, the first uplink signal being an uplink signal used for beam failure recovery. 
     In the embodiment of this disclosure, the priority of the first uplink signal is not configured or indicated, but is predefined, that is, it is defined in advance, and may be learnt in advance by both a network device and the terminal equipment, such as a lowest or highest priority in the system Therefore, a problem of signal conflict may be better resolved, so that the system is able to deal with a transmission relationship between the uplink signal and other uplink signals, thereby improving efficiency of the system.
