[0001] This application claims priority to Chinese Patent Application No. 201811646619.4, filed December 29, 2018, which is incorporated herein by reference in its entirety.

FIELD OF THE INVENTION

[0002] Embodiments of the present invention relate to the field of wireless communication technologies, and specifically to methods for receiving, transmitting information, user equipment and a network device.

BACKGROUND OF THE INVENTION

[0003] In Fifth Generation (5G) communication systems, physical control channel (PDCCH type 0) configuration information for scheduling system information is transmitted as part of a synchronization signal block/physical broadcast channel signal block (SS/PBCH block, or SSB) . In frequency bands up to 6 Hz for SSB/PBCH and PDCCH type 0 resources, multiplexing scheme 1 is used, which means that SSB/PBCH and PDCCH type 0 cannot coincide in the time domain. In this mode, the user equipment can monitor PDCCH type 0 in slot 0 (slot), in which the value of n0 satisfies the following condition:

; и если

, PDCCH типа 0 находится в четном цикле; или если

, PDCCH типа 0 находится в нечетном цикле, где μ - разнос поднесущих частот.[0004] For SSB index i

; and if

, PDCCH type 0 is in an even frame; or if

, PDCCH type 0 is in an odd cycle, where μ is the subcarrier spacing.

[0005] The values of M and O in the above formula are presented in Table 1:

[0006] Thus, as long as the configuration indices (i.e., indices 0-15) are defined, in the licensed 5G PDCCH type 0 system associated with each SSB are monitored in fixed slots based on time domain periodicity.

[0007] When operating a communication system on an unlicensed frequency band, before sending information to a subscriber equipment or a network device, it is necessary to perform a channel state assessment (extended channel state assessment - extended Clear Channel Assess, eCCA) to monitor channels, that is, to perform energy detection (Energy Detection , ED). When the energy indicator is below the threshold value, a transmission can only be started if the channel is determined to be idle. Due to the fact that the unlicensed bandwidth is shared by multiple technologies or multiple transmission points, this contention mode introduces an uncertainty in the channel availability time. When the channel is available (available), the opportunity to transmit the network signal may have already been missed, and it will not be possible to transmit. Therefore, there is a possibility that the receiving side will not be able to normally receive the signals configured from the network side and will not be able to provide the expected behavior of the user equipment according to the network configuration after receiving the signal, such as PDCCH monitoring, and monitoring and measuring the radio environment.

[0008] Thus, in a communication system with unlicensed frequency bands, the methods of sending information from the network side and receiving information by the user equipment represent technical problems that urgently need to be solved.

[0038] FIG. 1 is a schematic view of the architecture of a wireless communication system according to one embodiment of the present invention.

[0042] FIG. 2 is a flow diagram of a method for receiving information according to one embodiment of the present invention. This method is applied to user equipment and includes the following steps.

[0043] Step 21: SSB discovery;

[0044] Step 22: determining a potential SSB set quasi-aligned with the first detected SSB based on the transmission configuration information for the first information set, where the first information set includes the SSB.

[0045] Step 23: first processing based on the first SSB and the candidate set of SSBs, the processing including one of the following:

receiving system information scheduled by the physical control channel associated with the first SSB;

radio channel monitoring; And

measurement of radio resource management.

[0046] According to this embodiment of the present invention, a search space for a physical control channel configured by using SSB and located in the same slot as the SSB is referred to as the first search space for the physical control channel associated with the SSB. For example, with reference to FIG. 3, it shows a search area for a physical control channel associated with SSB #0, represented by a search area 200, which is in the same slot as SSB #0 and is indicated by the same lines as SSB #0; and the first search area for the physical control channel associated with SSB #1, represented by search area 200, which is in the same slot as SSB #1 and is also located before SSB #1 and is indicated by the same lines as SSB # 1.

[0047] The first search space for the physical control channel associated with the detected first SSB and the first search space for the physical control channel associated with the detected candidate SSB are collectively referred to as the search space for the physical control channel associated with the first SSB.

[0048] According to this embodiment of the present invention, the physical control channel may be represented by a Type 0 PDCCH.

[0049] The method of this embodiment of the present invention can be applied to an unlicensed communication system.

[0050] In an unlicensed communication system, all SSBs, the physical control channel associated with the SSB, as well as system information scheduled by that physical control channel, can only be transmitted after estimating the channel state. In an unlicensed communications system, the signals are generally transmitted together, for example by using a cellular Discovery Reference Signal (DRS) for more efficient transmission of information. Thus, all broadcast signals can be successfully transmitted with just a single idle channel detection. In addition, due to the importance of the information and to ensure that it is likely to be transmitted within a potential time window (such as the DRS window), several potential provisions need to be included.

[0051] According to this embodiment of the present invention, the first information set may be represented by the DRS.

[0052] According to this embodiment of the present invention, the user equipment receives system information scheduled by the physical control channel associated with the detected SSB based on the transmission configuration information for the first information set contained in the SSB or the transmission configuration information specified by the protocol, or performs radio link monitoring or radio resource management measurement. Because the transmission configuration information can be transmitted by the SSB, the configuration of the first search area of the physical control channel associated with the SSB can be flexibly configured.

[0053] According to this embodiment of the present invention, the transmission configuration information includes at least one of the following:

information set 1: positions of the SSB and the first search areas for physical control channels associated with the SSB in the slot;

information set 2: the number n of search areas for physical control channels in one slot, where n is a positive integer greater than or equal to 1;

information set 3: potential transmission time window period T;

information set 4: duration L of the potential transmission time window;

information set 5: quasi-co-registration factor q for SSB within a potential transmission time window; And

information set 6: number and/or positions of SSBs transmitted in one slot, where

the potential transmission time window is represented by the transmission time window of the first information set.

[0054] The information may be included in the SSB or specified by the protocol, or may be partially included in the SSB or partially specified by the protocol.

[0055] Additionally, q may represent the maximum number of SSBs without quasi-co-occurrence in a potential transmission time window.

[0056] According to this embodiment of the present invention, information set 1 (SSB positions and positions of first search areas for SSB-related physical control channels in a slot) may be included in the SSB or be defined by the protocol.

[0057] According to this embodiment of the present invention, information set 2 (number of n search areas for physical control channels in one slot) may be included in the first SSB. Thus, different values of n can be adjusted to suit different situations. In addition, the value of n can be 1 or 2.

[0058] According to this embodiment of the present invention, information set 2 can be determined based on the amount of system information. If the amount of system information is less than the threshold value, the slot can be configured with two search areas for physical control channels. With regard to FIG. 3, in the embodiment shown therein, two search areas 200 for physical control channels (eg, symbols 0-13) are configured in one slot. If the amount of system information exceeds the threshold, the slot can be configured with one search space for the physical control channel. With regard to FIG. 4, in the embodiment shown therein, one search space 200 for the physical control channel (eg, symbols 0-13) is configured in one slot.

[0059] According to this embodiment of the present invention, information set 3 (potential transmission time window period T) may be specified by the protocol or included in the first SSB, and when included in the first SSB, different values of T may be configured depending on different situations.

[0060] According to this embodiment of the present invention, information set 4 (length L of a potential transmission time window) may be specified by the protocol or included in the first SSB, and when included in the first SSB, different values of L may be configured depending on different situations.

[0061] Also according to this embodiment of the present invention, the information set 5 can be included in the first SSB, and thus different values of q can be set depending on different situations.

[0062] According to this embodiment of the present invention, information set 6 (number and/or positions of SSBs sent in one slot) can be included in the first SSB and thus customized for different situations. For example, one or two sent SSBs can be configured in one slot. With regard to FIG. 3, in the embodiment shown therein, two SSBs (eg, symbols 0-13) are sent in one slot.

[0063] Additionally, according to this embodiment of the present invention, configuration information regarding different frequencies (for example, FR1 and FR2), different sub-carrier spacings (for example, 30 and 60 kHz), or different maximum numbers (i.e., maximum SSB index values) of potential SSBs may differ.

[0064] Also according to this embodiment of the present invention, step 22 (determining a potential set of SSBs quasi-aligned with the detected first SSB based on transmission configuration information) may include:

[0065] Step 221: determining a potential transmission time window set based on the transmission configuration information and the first SSB index i, where the potential transmission time window is represented by the transmission time window of the first information set.

[0066] Step 222: determining, within the potential time window set, the position of the potential SSB set quasi-aligned with the first SSB.

[0067] According to some embodiments of the present invention, step 221 above (determining a potential set of transmission time windows based on the transmission configuration information and the first SSB index i) may include:

[0068] Step 2211: calculating the initial position t0 of the potential transmission time window based on the index i of the first SSB.

[0069] Step 2212: determining a potential set of transmission time windows based on the start position of the potential transmission time window corresponding to the first SSB, the period T of the potential transmission time window, and its length L.

[0070] According to some embodiments of the present invention, the initial position t0 of the potential time window corresponding to the first SSB can be calculated based on the following formula:

- положение отправки первого SSB, а

- длина символа.where i is the index of the first SSB,

- the position of sending the first SSB, and

- character length.

[0071] According to some embodiments of the present invention, a potential transmission time window W0 may be calculated based on the following formula:

where m = 0, 1, 2, ..., T is the period of the potential transmission time window and L is the duration of this window.

[0072] Also according to some embodiments of the present invention, the above step 222 (determining the position of a potential set of SSB quasi-aligned with the first SSB in a potential set of transmission time windows) includes:

[0073] Step 2221: determining a candidate SSB set index based on the index i of the first SSB, the number n of search spaces for physical control channels in one slot, and the quasi-alignment factor q for SSBs in the potential transmission time window.

[0074] Step 2222: determining the position of the candidate SSB set in the candidate set of transmission time windows based on the candidate SSB set index.

mod q=

mod q.[0075] According to some embodiments of the present invention, the SSB candidate set index i0 satisfies the following values:

mod q=

mod q.

[0076] In addition, according to some embodiments of the present invention, the first information set further includes a physical control channel associated with the SSB, as well as system information scheduled by that physical control channel.

[0077] In some embodiments of the present invention, step 23 above (receiving system information scheduled by the physical control channel associated with the SSB) may include:

[0078] Step 231: determining a first search area of a physical control channel associated with the first SSB, as well as a candidate group of first search areas for physical control channels associated with the candidate set of SSBs, based on the positions of the SSBs and the first search areas for physical control channels, associated with SSB, in the slot.

[0079] Step 232: discovering a potential group of first search areas in a potential set of transmission time windows.

[0080] Step 233: determining the first search area for the physical control channel associated with the first SSB, as well as the detected potential group of first search areas as search areas for this physical control channel associated with the first SSB.

[0081] Step 234: Receiving system information scheduled by the physical control channel associated with the first SSB in a slot in which search areas for the physical control channel associated with the first SSB are located.

[0082] In this embodiment of the present invention, first, a potential set of SSBs quasi-aligned with the detected first SSB is determined based on this detected first SSB; thereafter, a first search area for a physical control channel associated with the first SSB and a potential set of first SSB search areas are determined; detecting potential first search areas; the first search area for the physical control channel associated with the first SSB, and the detected potential group of the first search areas are determined as a search area for the physical control channel associated with the first SSB; and in a slot in which a search space for a physical control channel associated with the first SSB is located, system information scheduled by that channel is received.

[0083] In other embodiments of the present invention, the above step 23 (receiving system information scheduled by the physical control channel associated with the SSB) may include:

determination step 231': determining a first search area for a physical control channel associated with the first SSB based on the positions of the SSB and the first search areas for physical control channels associated with the SSB in the slot;

SSB determination step 232': determination of a potential set of SSBs within a potential transmission time window; And

receiving step 233': determining a candidate group of first search areas for physical control channels associated with the candidate set of SSBs based on the positions of the SSBs and the first search areas for physical control channels associated with the SSB in the slot; defining a first search space for a physical control channel associated with the first SSB and a candidate group of first search spaces for physical control channels associated with the detected candidate set of SSBs as search spaces for the physical control channel associated with the first SSB; and receiving system information scheduled by the physical control channel associated with the first SSB in a slot in which search areas for the physical control channel associated with the first SSB are located.

[0084] In this embodiment of the present invention, first, a potential set of SSBs quasi-aligned with the detected first SSB is determined based on this detected first SSB; after that, potential SSBs are detected at the position of a certain potential set of SSBs; first search areas are determined for the physical control channels associated with potential SSBs; a first search space for a physical control channel associated with the first SSB and a detected group of first search spaces for physical channels associated with the candidate set of SSBs are determined as a search space for the physical control channel associated with the first SSB; and in a slot in which a search space for a physical control channel associated with the first SSB is located, system information scheduled by that channel is received.

[0085] According to some embodiments of the present invention, the step of determining SSB 232' may include:

detecting a potential set of SSBs in a potential transmission time window in chronological order; And

terminating the discovery process within the potential transmission time window and proceeding to the receive stage if a potential SSB is detected in the potential transmission time window, but it is not present in the next potential position of the potential SSB.

[0086] In general, SSBs in a potential transmission time window are sent in contiguous slots. In other words, when detecting a candidate set of SSBs within a potential transmission time window, if a potential SSB is detected in that time window but not detected at the next candidate position, the SSB transmission within the potential transmission time window is considered to be over. In this case, the process of detecting a potential set of SSBs within a potential transmission time window is stopped in order to reduce the amount of user equipment overhead.

[0087] In some embodiments of the present invention, after the receiving step 233', the present method further includes:

decryption step 234': combining and decrypting the received system information; And

obtaining system information upon successful decryption; or buffering the received system information on a failed decryption and performing a potential SSB set discovery within the next potential transmission time window, and performing a receive step 233' and a decryption step 234' until the decryption is successfully completed.

[0088] According to some embodiments of the present invention, receiving system information scheduled by the physical control channel associated with the first SSB includes: performing rate matching on the SSB in the slot in which the system information is located, i.e., receiving system information scheduled by the physical control channel outside the SSB position.

[0089] In some embodiments of the present invention, if the user equipment for radio bearer monitoring or radio resource management is configured to measure the first SSB, the above step 23 (radio bearer monitoring or radio resource management measurement) includes:

[0090] Step 231'': detecting a potential set of SSBs in a potential transmission time window in chronological order.

[0091] Step 232'': radio channel monitoring or radio resource management measurement if the first number of potential SSB sets are detected.

[0092] Step 233'': Otherwise, continue performing the discovery step on the candidate SSB set within the next candidate transmission time window until the first number of candidate SSB sets has been discovered.

[0093] According to some embodiments of the present invention, the first number is less than or equal to the value X/q, where X is the maximum number of consecutive SSBs transmitted within a potential transmission time window, and q is the SSB quasi-aliasing factor in that time window.

[0094] In the above embodiment of the present invention, the candidate set of SSBs quasi-aligned with the first SSB are all candidate sets of SSBs quasi-aligned with the first SSB in the candidate set of transmission time windows.

[0095] FIG. 5 is a flowchart of a method for transmitting information according to one embodiment of the present invention; This method is applied to a network device and includes the following steps.

[0096] Step 51: detecting an idle channel in a potential transmission time window, which is represented by the transmission time window of the first information set.

[0097] Step 52: transmitting the first information set on the detected idle channel based on the transmission configuration information for the first information set that includes the SSB, and this SSB contains the transmission configuration information.

[0098] According to this embodiment of the present invention, when transmitting an SSB, a network device may use the SSB as a carrier of transmission configuration information for the first information set; and based on the transmission configuration information, the user equipment can receive system information scheduled by the physical control channel associated with the detected SSB, or perform radio channel monitoring or radio resource management measurement. Because the configuration information can be transmitted via SSB, it is possible to flexibly configure the search area of the physical control channel associated with the SSB.

[0099] According to some embodiments of the present invention, the first information set further includes a physical control channel associated with the SSB, as well as system information scheduled by that physical control channel. Based on the first information set, the user equipment can receive system information scheduled by the physical control channel associated with the SSB.

[0100] According to this embodiment of the present invention, a search space for a physical control channel configured by using SSB and located in the same slot as SSB is referred to as a first search space for a physical control channel associated with SSB.

[0101] The first search space for the physical control channel associated with the detected first SSB and the first search space for the physical control channel associated with the detected potential SSB are collectively referred to as the search space for the physical control channel associated with the first SSB.

[0102] According to this embodiment of the present invention, the physical control channel may be represented by PDCCH type 0.

[0103] The method of this embodiment of the present invention can be applied to an unlicensed communication system.

[0104] According to this embodiment of the present invention, the transmission configuration information includes at least one of the following:

information set 1: positions of the SSB and the first search areas for physical control channels associated with the SSB in the slot;

information set 2: the number n of search areas for physical control channels in one slot, where n is a positive integer greater than or equal to 1;

information set 3: potential transmission time window period T;

information set 4: duration L of the potential transmission time window;

information set 5: quasi-co-registration factor q for SSB within a potential transmission time window; And

information set 6: number and/or positions of the SSBs transmitted in one slot.

[0105] According to this embodiment of the present invention, information set 1 (SSB positions and positions of first search areas for SSB-related physical control channels in a slot) may be included in the SSB or be defined by the protocol.

[0106] Additionally, q may represent the maximum number of SSBs without quasi-co-occurrence in a potential transmission time window.

[0107] According to this embodiment of the present invention, information set 2 (number of n first search areas for physical control channels in one slot) may be included in the first SSB. Thus, different values of n can be adjusted to suit different situations. In addition, the value of n can be 1 or 2.

[0108] According to this embodiment of the present invention, the number n of search areas for physical control channels in one slot in infoset 2 can be determined by the size of the system information block. If the amount of system information is less than the threshold value, one slot can be configured with two search areas for physical control channels. With regard to FIG. 3, in the embodiment shown therein, two search areas 200 for physical control channels (eg, symbols 0-13) are configured in one slot. In this case, the network device can perform idle channel detection within a potential transmission time window based on a monitoring scope of 0.5 slots (7 characters) (i.e., for every seven characters there is one Listen Before Talk opportunity ( LBT)) If the amount of system information exceeds the threshold value, the slot can be configured with one search area for the physical control channel.Referring to FIG. control channel (e.g., characters 0-13) In this case, the network device can perform idle channel detection within a potential transmission time window based on a monitoring scope of 1 slot (14 characters) (i.e., for every 14 characters, there is one opportunity LBT).

[0109] According to this embodiment of the present invention, information set 3 (potential transmission time window period T) may be specified by the protocol or included in the first SSB, and when included in the first SSB, different values of T may be configured depending on different situations.

[0110] According to this embodiment of the present invention, information set 4 (length L of a potential transmission time window) may be specified by the protocol or included in the first SSB, and when included in the first SSB, different values of L may be configured depending on different situations.

[0111] Also according to this embodiment of the present invention, the information set 5 can be included in the first SSB, and thus different values of q can be set depending on different situations.

[0112] According to this embodiment of the present invention, information set 6 (number and/or positions of SSBs sent in one slot) can be included in the first SSB and thus customized for different situations. For example, one or two sent SSBs can be configured in one slot. With regard to FIG. 3, in the embodiment shown therein, two SSBs (eg, symbols 0-13) are sent in one slot.

[0115] For example, if n is 1, the amount of monitoring is 1 slot; or if n is 2, the monitoring scope is 0.5 slots.

[0016] According to this embodiment of the present invention, the number n of search spaces for physical control channels in one slot is determined by the amount of system information.

[0117] The following is a description of the above methods for transmitting and receiving information of the present invention by way of examples and with reference to specific embodiments of the invention.

[0119] The index of the first symbol in the above table 2 represents the positions of the first search areas for physical control channels associated with the SSB in one slot (information set 1) according to the above embodiment.

[0120] The number of search areas per slot is the number n of search areas for physical control channels per slot (information set 2) according to the above embodiment.

[0121] The DRS window (DRS window) is a potential transmission time window according to the above embodiment. The DRS window period is a potential transmission time window period T (information set 3) according to the above embodiment. Duration of the DRS window - the duration L of the potential transmission time window (information set 4) according to the above embodiment.

[0122] The q QCL number is the quasi-co-registration coefficient q for SSB within a potential transmission time window (information set 5) in the above embodiment.

[0123] According to the above table, when the indexes (index) of different transmission configuration information are different, the transmission configurations for the corresponding first information set are at least partially different.

[0124] According to this embodiment of the present invention, when transmitting the first information set, the network device may cause the transmission configuration information to be included in the SSB, or only the transmission configuration information index to be included. One index represents one set of transmission configuration information.

[0125] With regard to FIG. 6, when the network device determines the need to transmit the first information set based on the transmission configuration information with index 0, it performs idle channel detection within a DRS window (6 ms) based on a monitoring scope of 1 slot (n is 1). There are 12 (since each slot is 0.5 ms, there are 12 slots in total within 6 ms) LBT transmission opportunities.

[0126] In the embodiment shown in FIG. 6, the network device detects an idle channel in the 2nd slot (i.e., slot #1) of the DRS window and transmits the first information set (SSB, Type 0 PDCCH associated with SSB, and system information scheduled by this Type 0 PDCCH) at 2 th and 3rd (that is, slot #3) slots. The network device detects an idle channel in the 11th slot (ie, slot #10) of another DRS window and sends the first information set to the 11th and 12th (ie, slot #11) slots.

[0127] In the embodiment shown in FIG. 6, there are two non-QCL SSBs in one DRS window, i.e., SSBv1 and SSBv0, and hence q = 2.

[0128] In the embodiment shown in FIG. 6, one PDCCH type 0 is transmitted per slot. Two SSBs are transmitted per slot.

[0128] In the embodiment shown in FIG. 6, when the configuration information index is 0, the index of the first symbol (that is, the position of the type 0 PDCCH in the slot) is 0, which means that the type 0 PDCCH is located in the first symbol of the slot.

Embodiment 2 of the present invention

[0129] The configuration information in Table 2 is still used as an example.

[0130] With regard to FIG. 6, when the network device determines the need to transmit the first information set based on the transmission configuration information with index 1, it performs idle channel detection within a DRS window (3 ms) based on a monitoring amount of 0.5 slots. There are 12 (so 0.5 slots is 0.25 ms, within 3 ms a total of 12 slots fit) LBT transmission opportunities.

[0131] In the embodiment shown in FIG. 7, the network device detects an idle channel in the 1st slot (that is, slot #0) of the DRS window and transmits the first information set (SSB, Type 0 PDCCH associated with SSB, and system information scheduled by this Type 0 PDCCH) in the slots. from the first 1st to the 3rd (that is, slots No. 0, 1 and 2). The network device detects an idle channel in the 3rd slot (ie, slot #2) of another DRS window and sends the first information set to the 3rd and 4th (ie, slot #3) slots.

[0132] In the embodiment shown in FIG. 7, there are four non-QCL SSBs in one DRS window, i.e., SSBv0, SSbV1, SSbV2, and SSBv3, and hence q = 4.

[0133] In the embodiment shown in FIG. 7, two Type 0 PDCCHs are transmitted in one slot. Two SSBs are transmitted in one slot.

нечетный}. Это значит, что 1-е окно DRS, первая область поиска (PDCCH типа 0), связанная с SSB № 1, расположены в символе 7 в том же слоте (слот № 0), а PDCCH типа 0, связанный с SSB № 2, расположен в символе 0 в том же слоте (слот № 1).[0134] In the embodiment shown in FIG. 7, when the configuration information index is 1, the index of the 1st symbol (that is, the slot position of the PDCCH type 0) is {0 if

even} or {7 if

odd}. This means that the 1st DRS window, the first search space (PDCCH type 0) associated with SSB #1 is located in symbol 7 in the same slot (slot #0), and the PDCCH type 0 associated with SSB #2 is located at symbol 0 in the same slot (slot #1).

Embodiment 3 of the present invention

[0135] Referring to FIG. 8, in contrast to the embodiment shown in FIG. 6 is that, in this embodiment, the network device performs the configuration of infoset 6, that is, the number and/or positions of the SSBs transmitted in one slot. In the embodiment shown in FIG. 8, one SSB is transmitted per slot.

Embodiment 4 of the present invention

[0136] With regard to FIG. 9, assuming that the network device sends the first information set based on the configuration information with index 0, the user equipment 1 (UE 1) monitors the SSB on the operating carrier frequency, detects the SSB Nos. 2 and 3, and also obtains the transmission configuration information with the index 0 based on the transmission configuration information contained in SSB Nos. 2 and 3. In addition, UE 1 obtains the start time of the DRS window based on monitoring for SSB No. 2, and may obtain an absolute time window for DRS based on the period and duration of this DRS window, that is, the part of the slot highlighted in gray in FIG. 9. Based on the QCL configuration, positions of potential UE1 type 0 PDCCHs can be obtained. When decrypting the system information, UE1 performs SSS (secondary synchronization signal)/PSS (primary synchronization signal) detection in slots in which type 0 PDCCHs are located, determines whether DRS has been transmitted, and if there is DRS performs blind discovery on PDCCH type 0 to decrypt system information.

Embodiment 5 of the present invention

[0137] It is assumed that the user equipment receives the transmission configuration information of the next RS RLM (reference signal - reference signal), that is, SSB with index No. 2. According to the standard definition, user equipment only needs to detect the status of SSB with index No. 2 in each DRS window. In this embodiment of the present invention, the user equipment, based on the configuration information contained in the SSB with index No. 2, obtains a number of positions of the SSB with an index that require monitoring when a DRS occurs, and these positions have the same QCL relationship and refer to the table configurations of this option. implementation. For example, when the transmission configuration information index is 0, this configuration instructs the user equipment to monitor the potential positions of SSB Nos. 2, 3, 6, 7, 10, 11, ..., SSB No. 22, and SSB No. 23. Assuming that X = 8, the user equipment uses a maximum of 8/2 = 4 SSB for RLM.

The touch panel 1271 may include two parts: a touch detection device and a touch controller. The touch detection device detects the direction of the user's touch, the signal transmitted in the touch operation, and transmits this signal to the touch controller. The touch controller receives touch information from the touch detection device, converts it into touch point coordinates, sends the coordinates to the processor 1210, and receives and executes a command from the processor 1210.

[0167] The storage device 129 may be for storing a software system program and various data. The storage device 129 may advantageously include a program storage area and a data storage space. The program storage area can store an operating system, an application program required for at least one function (for example, a sound playback function and a picture playback function), and so on. The data storage area may store data created by the user equipment (for example, audio data and a phone book) and the like. In addition, the storage device 129 may include high speed random access memory or read only memory, such as at least one magnetic disk, flash memory, or other non-volatile solid state storage devices.

[0168] Processor 1210 is a user equipment control center. The processor 1210 connects all parts of the entire user equipment through various interfaces and lines, and performs various functions and data processing of the user equipment by running or executing programs of the software system and/or module stored in the storage device 129, and accesses data stored in storage device 129, thereby providing a general control of the user equipment. The processor 1210 may include one or more processing devices. In addition, processor 1210 may be combined with an application processor and a modem processor. The application processor is primarily concerned with processing the operating system, user interface, application programs, and the like. The modem processor primarily handles wireless communication data. As can be appreciated, the above modem processor may alternatively not be embedded in processor 1210 either.

[0169] The user equipment 120 may further include a power supply 1211 (eg, a battery) to provide power to all components. In some cases, power supply 1211 may be logically coupled to processor 1210 via a power supply management system. Thus, the power supply control system realizes functions such as charge/discharge control and power consumption control.
