[0017] The disclosed technology provides implementation paradigms and examples of downlink control signaling in wireless communications. Some embodiments of the disclosed technology propose effective power saving techniques to instruct user equipment to perform its operations based on information included in DCI (Downlink Control Information). In some embodiments, DCI includes information to control one or more user equipment to help the user equipment save power consumption and improve performance.

[0018] Figure 1An example of a wireless communication system (e.g., a 5G or NR cellular network) is shown that includes a BS 120 and one or more user equipment (UE) 111, 112, and 113. In some embodiments, the UE uses an implementation of the disclosed technology (131, 132, 133) to access the BS (e.g., network), which then enables subsequent communication from the BS to the UE (141, 142, 143). The UE can be, for example, a smartphone, a tablet, a mobile computer, a machine to machine (M2M) device, an Internet of Things (IoT) device, etc.

[0019] Figure 2 An example of a block diagram representation of a portion of an apparatus is shown. An apparatus 210, such as a base station or a wireless device (or UE), may include processor electronics 220, such as a microprocessor that implements one or more of the techniques presented in this document. The apparatus 210 may include transceiver electronics 230 to send and / or receive wireless signals through one or more communication interfaces (such as antenna 240). The apparatus 210 may include other communication interfaces for sending and receiving data. The apparatus 210 may include one or more memories (not explicitly shown) configured to store information such as data and / or instructions. In some embodiments, the processor electronics 220 may include at least a portion of the transceiver electronics 230. In some embodiments, at least some of the disclosed techniques, modules, or functions are implemented using the apparatus 210.

[0020] The power consumption of user equipment is an important factor affecting user experience. Various embodiments of the disclosed technology provide power saving techniques for user equipment in a wireless communication system. In some embodiments of the disclosed technology, in order to improve network performance, the power saving technique suggests encoding some information of one or more UEs (user equipments) together to reduce the size of the DCI payload.

[0021] When DRX (Discontinuous Reception) is configured, the UE does not have to continuously monitor the PDCCH (Physical Downlink Control Channel). Figure 3 An example of a DRX cycle with some parameters is shown. The characteristics of DRX are as follows:

[0022] - On duration: The duration that the UE waits to receive the PDCCH after waking up. If the UE successfully decodes the PDCCH, the UE remains awake and starts the inactivity timer;

[0023] - Inactivity timer: The duration that the UE waits to successfully decode the PDCCH, starting from the last successful decoding of the PDCCH. If it fails, it can go back to sleep. Only for the first transmission (i.e., not for retransmissions), after a single successful decoding of the PDCCH, the UE shall restart the inactivity timer;

[0024] - Retransmission timer: duration until retransmission can be expected;

[0025] - Period: specifies the periodic repetition of the on-duration followed by a possible inactive period;

[0026] -Activation time: The total duration that the UE monitors the PDCCH. This includes the "on duration" of the DRX cycle, the time that the UE performs continuous reception when the inactivity timer has not expired, and the time that the UE performs continuous reception while waiting for a retransmission opportunity.

[0027] Even with DRX configuration, the UE needs to wake up periodically to monitor the PDCCH, which may result in unnecessary power consumption when no data is transmitted or received during the On-Duration.

[0028] For PDCCH monitoring, the period of the search space can be configured through RRC (Radio Resource Control) signaling. Multiple (e.g., up to 10) search spaces can be configured for each downlink BWP (bandwidth part). The PDCCH monitoring timing within the search space is related to the period, offset and duration, PDCCH monitoring mode within the time slot, etc. Figure 4 An example of a schematic diagram illustrating PDCCH monitoring is shown. Figure 4 In the example, the period is 4 slots, the offset is 1 slot, and the duration is 2 slots. The PDCCH monitoring pattern within a slot is a 14-bit bitmap. In the example, the PDCCH monitoring occasion is configured by higher layer signaling.

[0029] For BWP adaptation, the UE may be configured with multiple BWPs. Dynamic BWP switching may be implemented through DCI indication and / or timer.

[0030] For CA-DC (Carrier Aggregation-Duel Connection) operation, a Scell ​​(Secondary Cell) may be deactivated by a timer or a MAC CE (Control Element).

[0031] For current solutions in the spatial domain, MIMO configuration (eg, configuring the number of antenna ports) depends on UE capabilities, channel conditions, higher layer parameters, etc. The spatial configuration cannot dynamically adapt to the arriving traffic.

[0032] In the time domain, the time domain resource allocation parameters include K0, K1, K2 and A-CSI (Aperiodic CSI) offset. A list of some examples of time domain resource allocation parameters (such as K0, K1 and K2) is configured by RRC signaling, and the actual parameters used in scheduling are indicated by DCI (Downlink Control Information). The A-CSI (Aperiodic CSI) offset is related to the QCL (quasi-co-location) type. In the current scheme, the UE does not know the time domain resource allocation before the PDCCH is decoded, or the time domain resource allocation is related to the QCL type, which potentially increases the power consumption of the UE.

[0033] K0: The time slot offset between the DCI and the PDSCH (Physical Downlink Shared Channel) it schedules

[0034] K1: Timing of a given PDSCH to DL (downlink) ACK (acknowledgement);

[0035] K2: The time slot offset between the DCI and the PUSCH (Physical Uplink Shared Channel) it schedules

[0036] A-CSI offset aperiodicTriggeringOffset is the offset between the time slot containing the DCI that triggers a set of aperiodic NZP (Non-ZeroPower) CSI-RS resources and the time slot in which the CSI-RS resource set is sent.

[0037] In order to further reduce UE power consumption, some embodiments of the disclosed technology provide a more energy-saving method, which introduces a power saving signal to instruct the UE to wake up when necessary. In some embodiments, the power saving signal can be configured with other functions, such as PDCCH monitoring information, BWP switching, Scell ​​operation, spatial domain information, time domain information, SRS request, CSI request, QCL information, etc., to further reduce power consumption or improve network performance.

[0038] Some embodiments of the disclosed technology provide Figure 5 and Figure 6 The wireless communication method shown. Figure 5In some embodiments, the method includes sending control signaling by a network device to a user equipment, the control signaling including N data blocks indicating T trigger states of M user equipments, and wherein N, T, and M are natural numbers, and the trigger state indicates configuration information of the M user equipments. In some embodiments, the control signaling includes a control information format indication. In some embodiments, the control signaling includes a functional indication. In some embodiments, N is equal to 1.

[0039] exist Figure 6 In some embodiments, the method includes: receiving control signaling by a user equipment from a network device, the control signaling including N data blocks indicating T trigger states of M user equipments, wherein N, T and M are natural numbers, and the trigger state indicates configuration information of the M user equipments. In some embodiments, the control signaling includes a control information format indication. In some embodiments, the control signaling includes a functional indication. In some embodiments, N is equal to 1.

[0040] Example 1

[0041] In some implementations, each of the M user equipments is configured with one data block.

[0042] In some examples, the fields of the data block are defined in Table 1. For a UE configured with a data block, trigger state-0 is indicated by a value or code point "00" of the data block, trigger state-1 is indicated by a value or code point "01" of the data block, trigger state-2 is indicated by a value or code point "10" of the data block, and trigger state-3 is indicated by a value or code point "11" of the data block.

[0043] [Table 1]

[0044]

[0045]

[0046] In some examples, multiple user equipments configured with the same parameter set may be indicated by the same data block. In this embodiment, the triggering status of multiple user equipments is encoded in one DCI payload. Therefore, compared with the scheme of encoding the triggering status of multiple user equipments separately, the resource overhead can be greatly reduced.

[0047] In some embodiments, the user equipment is configured with location information. In some embodiments, the location information is used to configure the UE to extract the trigger state from the DCI payload. In some embodiments, the interpretation of the trigger state of the user equipment is associated with the location information. In some embodiments, the location information includes the starting position and / or the ending position of the data block. In some embodiments, the location information includes an index of a block number. In some embodiments, the location information includes the bit width of the data block or the size of the data block field. In some embodiments, the location information is configured by high-level signaling. In some embodiments, the high-level signaling includes RRC signaling or MAC CE.

[0048] Example 2

[0049] In some embodiments, when the control signaling includes N data blocks, N is equal to 1. In some embodiments, the triggering status of M user equipments or multiple user equipments is jointly encoded. The triggering status of M user equipments or multiple user equipments is jointly encoded and indicated by a single value of the data block.

[0050] Examples of data block values ​​are defined in Table 2. In this example, the trigger states or configurations of multiple (e.g., M) user equipments are jointly encoded and indicated by a single value of the data block. In this example, there are 3 UEs (UE-0, UE-1, UE-2), and each of the UEs has 3 trigger states (with indexes of 0, 1, and 2). The value or code point "0" indicates a trigger state with index = 0 for UE-0, a trigger state with index = 0 for UE-1, and a trigger state with index = 0 for UE-2. The value or code point "1" indicates a trigger state with index = 1 for UE-0, a trigger state with index = 0 for UE-1, and a trigger state with index = 0 for UE-2, and so on.

[0051] [Table 2]

[0052]

[0053]

[0054] In this embodiment, the trigger states of multiple user devices are jointly encoded in a data block and indicated by a value of the data block. Therefore, compared with Example 1, the payload size can be reduced and the performance can be improved. More specifically, in the case where there are 3 user devices and each user device has 3 trigger states, 2 (three trigger states) × 3 (number of user devices) = 6 bits are required for Example 1. However, for Example 2, 5 bits are sufficient to indicate 3*3*3=27 combinations. Therefore, in this example, one bit can be reduced. In the case of different numbers of user devices and different numbers of trigger states for each user device, more examples of the reduced number of payload bits compared to Example 1 are given in Table 3.

[0055] [Table 3]

[0056]

[0057] In those embodiments, trigger status or configuration information is encoded together to reduce resource overhead and improve the performance of the wireless communication system. Figure 7 An example of BLER (Block Error Rate) performance is given in Figure 7 In the figure, “Case-1” is the performance of the technology discussed in Example-2 when there are 8 user devices and each user device has 17 trigger states, and the figure of “Case-2” is the performance of the technology discussed in Example-1.

[0058] In some embodiments, the trigger state of the user equipment indicated by the network is determined by or associated with at least one of: the value of the data block, the number of trigger states of each user equipment, the mapping order of M user equipments, the number of trigger states of previous user equipments, the number of trigger states of user equipments with lower valid positions, the number of trigger states of user equipments with higher mapping orders, the mapping order of previous user equipments, the order of user equipments with lower valid positions, the order of user equipments with higher mapping orders, the mapping positions of user equipments, or the number of trigger states of user equipments.

[0059] In some embodiments, the value of the data block is determined by or associated with at least one of: a trigger state of a user equipment indicated by the network, the number of trigger states of each user equipment, a mapping order or index of M user equipments, the number of trigger states of previous user equipments, the number of trigger states of user equipments with lower valid positions, the number of trigger states of user equipments with higher mapping orders, the mapping order or index of previous user equipments, the order of user equipments with lower valid positions, the order of user equipments with higher mapping orders, the mapping order or index of user equipments, or the number of trigger states of user equipments.

[0060] In some embodiments, the mapping order of the M user devices includes the order in which the values ​​of the data blocks are specified. In some examples, the value of the data block C is determined by the following equation:

[0061] C=a(Inf-UE-0)+b(Inf-UE-1,Inf-UE-0)+c(Inf-UE-2,Inf-UE-1,Inf-UE-0)+...+d(Inf-UE-N-1,Inf-UE-N-2,...,Inf-UE-1,Inf-UE-0).

[0062] In some examples, t0=e(C, Inf-UE-0), t1=f(C, Inf-UE-0, Inf-UE-1), t2=g(C, Inf-UE-0, Inf-UE-1, Inf-UE-2),…, tN-1=h(C, Inf-UE-0, Inf-UE-1, Inf-UE-2.., Inf-UE-N-1), where a(x), b(x), c(x), d(x), e(x), f(x), g(x) and h(x) represent functions of x, and ti represents the indicated trigger state of the user equipment, 0≤i≤N-1, and Inf-UE-i represents the information of UE-i, 0≤i≤N-1.

[0063] In some implementations, the codepoint or value of the data block and the trigger state of the user equipment are determined as follows:

[0064] [Table 4]

[0065]

[0066]

[0067] In some implementations, the code point or value of the data block and the trigger state of the user equipment are determined as follows:

[0068] [Table 5]

[0069]

[0070] In some embodiments, the code point or value of the data block and the trigger state of the user equipment are determined as follows: C = t0+t1*T0+t2*T0*T1+....+t(N-1)*T0*T1*T2*T(N-2), where Ti is the number of trigger states of the i-th user equipment, and for 0≤i≤N-1, Ti is a natural number; ti is the index of the trigger state of the i-th user equipment, and for 0≤i≤N-1, ti is a natural number; C is the code point of the data block.

[0071] In the example, the mapping order of the user equipment is UE-0, UE-1, UE-2, ..., UE-N-1. In the example, the user equipment with a smaller index is in front of or before the user equipment with a larger index. In the example, the user equipment with a smaller index has a lower effective position. In the example, the user equipment with a smaller index has a higher mapping order.

[0072] In some embodiments, the predefined condition includes at least one of the following: i) the trigger state of UE-i indicated by the data block is derived from or associated with the information or parameter of UE-j, ii) the derivation of the trigger state of UE-j indicated by the data block does not require the information or parameter of UE-i or is not associated with the information or parameter of UE-i. Wherein i and j are different user equipment indexes, and i and j are natural numbers.

[0073] In an example, the user equipment UE-j is in front of or before the user equipment UE-i when the predefined condition is met. In an example, the user equipment UE-j has a lower effective position than the user equipment UE-i when the predefined condition is met. In an example, the user equipment UE-j has a higher mapping order than the user equipment UE-i.

[0074] In some embodiments, the mapping order is represented by the index of the user equipment. In some examples, the user equipment with a smaller index has a lower mapping order. In some examples, the user equipment with a larger index has a lower mapping order.

[0075] Take Table 2 as an example. There are 3 UEs (UE-0, UE-1, UE-2), and each of the UEs has 3 trigger states (indexed as 0, 1, 2). If the value of the data block is 3, the trigger index of UE-0 is t0=mod(C, T0)=mod(3, 3)=0, t1=mod(C / T0, T1)=mod(floor(3 / 3), 3)=1, t2=mod(C / T0 / T1, T2)=mod(floor(3 / 3 / 3), 3)=1. On the contrary, if the indexes of the indicated trigger states of UE-0, UE-1 and UE-2 are 2, 1, 1, the value of the data block is C=t0+T0*t1+T0*T1*t2=2+3*1+3*3*1=14.

[0076] In some embodiments, the user equipment is configured with at least one of: information on the number of trigger states of each user equipment, information on the mapping order or index of M user equipment, information on the number of trigger states of previous user equipment, the number of trigger states of user equipment with lower valid positions, the number of trigger states of user equipment with higher mapping order, the mapping order or index of previous user equipment, the order of user equipment with lower valid positions, the order of user equipment with higher mapping order, the mapping order or index of user equipment, or the number of trigger states of user equipment.

[0077] In some embodiments, the information of the number of trigger states of each user equipment, or the information of the number of trigger states of the previous user equipment, or the information of the number of trigger states of the user equipment with a lower effective position, or the information of the number of trigger states of the user equipment with a higher mapping order is in the form of a list or set format. In some embodiments, the index in the list or set indicates the mapping order. For example, there are three user equipments, and the user equipment is configured with a list of values ​​[3,5,7], which correspond to the number of trigger states of UE-0, UE-1, and UE-3, respectively. In the example, the mapping order is first UE-0, then UE-1, and finally UE-2.

[0078] In some embodiments, the trigger state indicated by the block is determined by information of a previous user equipment, or information of a user equipment with a lower valid position, or information of a user equipment with a higher mapping order, or is associated with information of a previous user equipment, or information of a user equipment with a lower valid position, or information of a user equipment with a higher mapping order. For example, there are three previous user equipments, and the user equipments are configured with a list of values ​​[3, 5, 7], which correspond to the number of trigger states of UE-0, UE-1, and UE-3, respectively.

[0079] For example, when there are three previous user equipments, the fourth user equipment may be configured with a list of values ​​corresponding to the number of trigger states of the first three user equipments [3, 5, 7]. For example, when there are three user equipments with lower effective positions or higher mapping orders, the fourth user equipment may be configured with a list of values ​​corresponding to the number of trigger states of the first three user equipments [3, 5, 7].

[0080] In some embodiments, the information of the number of trigger states of each user equipment, or the information of the number of trigger states of the previous user equipment, or the information of the number of trigger states of the user equipment with a lower effective position, or the information of the number of trigger states of the user equipment with a higher mapping order is in the format of a differential value. By means of the differential method, the signaling overhead can be reduced.

[0081] In some embodiments, the trigger state indicated by the data block is determined by or associated with a mapping order or index of the user equipment and the number of trigger states of the user equipment. In some embodiments, the number of trigger states of the user equipment is the same. The user equipment can interpret the trigger state indicated by the data block using its mapping order or index and the number of trigger states.

[0082] In some examples, the indicated trigger state is ti=mod(operation-i(C / T_temp),T), where for 0≤i≤N-1, T_temp=T^(i), T is the number of trigger states for each user equipment, T is a natural number; ti is the index of the indicated trigger state of the i-th user equipment, for 0≤i≤N-1, ti is a natural number; C is the code point of the data block; for 0≤i≤N-1, operation-i is a rounding operation. In this example, "^" is used to indicate a power function, and thus T^(i) indicates T i .

[0083] In some examples, the indicated trigger state is C = t0 + t1*T + t2*T^2 + .... + t(N-1)*T^(N-2), where T is the number of trigger states for each user device, and T is a natural number; ti is the index of the indicated trigger state of the i-th user device, and for 0≤i≤N-1, ti is a natural number; C is the code point of the data block.

[0084] Both Embodiment 1 and Embodiment 2 can reduce resource overhead and blocking rate, and Embodiment 2 can further reduce the size of the load.

[0085] In some embodiments, the control signaling may be included in a first group of DCI formats or a first group of DCI candidates. The first group of DCI formats or the first group of DCI candidates have a higher mapping priority than the second group of DCI formats or the second group of DCI candidates. The first group of DCI formats or the first group of DCI candidates and the second group of DCI formats or the second group of DCI candidates are distinguished by at least one of the following: DCI format, RNTI (Radio network temporary identifier), search space configuration, CORESET (control resource set) configuration, time resources or frequency resources. In some embodiments, the second group of DCI formats or the second group of DCI candidates include at least one of the following: DCI format 0-0, DCI format 0-1, DCI format 1-0, DCI format 1-1, DCI format 2-0, DCI format 2-1, DCI format 2-2, DCI format 2-3. In some embodiments, the first group of DCI formats or the first group of DCI candidates are DCI formats other than DCI format 0-0, DCI format 0-1, DCI format 1-0, DCI format 1-1, DCI format 2-0, DCI format 2-1, DCI format 2-2, and DCI format 2-3. In some embodiments, the CRC of the second group of DCI formats or the second group of DCI candidates is scrambled by at least one of the following: C-RNTI, CS-RNTI, MCS-C-RNTI, TC-RNTI, SP-CSI-RNTI, P-RNTI, SI-RNTI, RA-RNTI, TC-RNTI, SFI-RNTI, INT-RNTI, TPC-PUSCH-RNTI, and TPC-PUCCH-RNTI. In some embodiments, the CRC of the first group of DCI formats is scrambled by RNTIs other than C-RNTI, CS-RNTI, MCS-C-RNTI, TC-RNTI, SP-CSI-RNTI, P-RNTI, SI-RNTI, RA-RNTI, TC-RNTI, SFI-RNTI, INT-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI. In some embodiments, resources configured for the first group of DCI formats or the first group of DCI candidates are not occupied by the second group of DCI formats or the second group of DCI candidates.

[0086] In some embodiments, the control signaling may be included in a first group of DCI formats or a first group of DCI candidates in which the CRC is scrambled by the PS-RNTI. The uses of the PS-RNTI include at least one of: reducing power consumption, indicating wake-up, indicating sleep, reducing PDCCH (physical downlink control channel) monitoring opportunities, switching BWP (bandwidth part), indicating spatial information, indicating time domain resource allocation, indicating QCL (Quasi-co-location) information, indicating SRS (Sounding Reference Signal) request or indicating CSI (Channel State Information) request.

[0087] In some embodiments, the data block includes field-1 and other fields. Field 1 of the data block includes one of the following configuration information 1 to 10. For example, field-1 includes a wake-up indication, and other fields include other configuration or trigger status information.

For example, when the UE is configured with two PDCCH search spaces, namely search space 1 with period 1 and search space 2 with period 2, it is assumed that the information transmitted in the DCI indicates that the UE does not need to monitor the PDCCH in the next 2 PDCCH monitoring periods. In this case, for search space 1, the UE does not need to monitor the PDCCH candidates in the next 2 periods with a duration equal to 2 times of period 1. For search space 2, the UE also does not need to monitor the PDCCH candidates in the next 2 periods with a duration equal to 2 times of period 2.

[0098] In some embodiments, the PDCCH monitoring period is equal to the maximum or minimum period of all search spaces. In some embodiments, the PDCCH monitoring period is equal to the maximum or minimum period of the search space of the second group of PDCCH candidates. For example, when the UE is configured with two PDCCH search spaces, i.e., search space 1 with period 1 and search space 2 with period 2 (wherein period 1 is less than period 2), it is assumed that the information transmitted in the DCI indicates that the UE does not need to monitor the PDCCH in the next 2 PDCCH monitoring periods. In this case, for both search space 1 and search space 2, the UE does not need to monitor the PDCCH candidates in the next 2 periods with a duration equal to 2 times that of period 1. The duration of the UE's inactive time is 2 times the maximum value of the periods in period 1 and period 2. Among them, the inactive time is the period when the UE does not need to monitor the PDCCH.

[0099] In some embodiments, the second group of PDCCH candidates includes at least one of the following: i) DCI format with CRC scrambled by C-RNTI, CS-RNTI, MCS-C-RNTI, TC-RNTI, SP-CSI-RNTI, P-RNTI, SI-RNTI, RA-RNTI, TC-RNTI, SFI-RNTI, INT-RNTI, TPC-PUSCH-RNTI, TPC-PUCCH-RNTI, ii) DCI format 0-0, DCI format 0-1, DCI format 1-0, DCI format 1-1, DCI format 2-0, DCI format 2-1, DCI format 2-2, DCI format 2-3.

[0100] In some implementations, the first set of PDCCH candidates includes a DCI format in which the CRC is scrambled by the PS-RNTI.

[0101] In some implementations, the bit width of the i-th block may be 1, where 0≤i≤N-1.

[0102] In some embodiments, when the value of the i-th block is value_1, it means that the UE needs to monitor the second group of PDCCH candidates or PDCCH candidates in the next N DRX cycles; when the value of the i-th block is value_2, it means that the UE does not need to monitor the second group of PDCCH or PDCCH candidates in the next N DRX cycles. In some embodiments, when the values ​​of the i-th block are all 0, it means that the UE does not need to monitor the second group of PDCCH candidates or PDCCH candidates in the next N DRX cycles, which means "do not wake up" or "enter sleep"

[0103] In some embodiments, when the value of the i-th block is value_1, it means that the UE needs to monitor the second group of PDCCH candidates or PDCCH candidates in the next N DRX cycles; when the value of the i-th block is value_2, it means that the UE does not need to monitor the second group of PDCCH or PDCCH candidates in the next N DRX cycles. In some embodiments, when the values ​​of the i-th block are all 0, it means that the UE does not need to monitor the second group of PDCCH candidates or PDCCH candidates in the next N DRX cycles, which means "do not wake up" or "enter sleep"

[0104] In some embodiments, when the value of the i-th block is value_1, it means the conversion of DRX on or DRX activation time to DRX off or DRX inactive time; when the value of the i-th block is value_2, it means the conversion of DRX off or DRX inactive time to DRX on or DRX activation time. In some embodiments, when the values ​​of the i-th block are all 0, it means the conversion of DRX on or DRX activation time to DRX off or DRX inactive time.

[0105] With the indication of the wake-up information, the UE does not need to wake up or can skip monitoring the PDCCH, which is beneficial to reducing power consumption.

[0106] Configuration information 2

[0107] Configuration information 2 may include information about BWP (Bandwidth Part) indication. If the UE does not support activation of BWP via DCI change, the UE shall ignore this information. Examples 1 to 3 are discussed below.

[0108] Example 1: The bit width for this configuration information is determined to be bits, of which

[0109] -If n BWP,RRC ≤3, then n BWP =n BWP,RRC+1, in which case the bandwidth part indicates the ascending order of the higher layer parameter BWP-Id. BWP,RRC It is the number of DL BWPs configured by higher layers, excluding the initial DL bandwidth part.

[0110] - Otherwise n BWP =n BWP,RRC , in this case, the bandwidth part indication is defined in Table 6.

[0111] If the UE does not support change of activated BWP via DCI, the UE ignores this information.

[0112] [Table 6: Bandwidth Partial Indication]

[0113]

[0114] Example 2: The bit width for this configuration information is determined to be bits, of which

[0115] -If n BWP,RRC ≤3, then n BWP =n BWP,RRC +1, in this case, the bandwidth part indicates the ascending order equivalent to the higher layer parameter BWP-Id; where n BWP,RRC The number of UL BWPs configured by higher layers, excluding the initial UL bandwidth part

[0116] - Otherwise n BWP =n BWP,RRC , in this case, the bandwidth part indication is defined in Table 6.

[0117] Example 3: In some embodiments, the BWP switching indication may be associated with a reference signal. In this case, the trigger status in the data block indicates that the BWP switches from a small BWP to a large BWP. A set of reference signals ( Figure 7 The TRS in T can also be other CSI-RS, or both, or other reference signals such as PT-RS) BWPswitchDelay In this example, the UE can obtain the channel status or beam information of the large BWP quickly after the BWP switching, which is beneficial to improving network performance.

[0118] For DCI-based BWP switching, after the UE receives a BWP switching request in time slot n of a serving cell, the UE may be able to receive PDSCH (for switching of DL-activated BWP) or send PUSCH (for switching of UL-activated BWP) on the new BWP on the serving cell on which the BWP switching occurs no later than time slot n+T BWPswitchDelay occur.

[0119] [Table 7: Example of BWP switching delay]

[0120]

[0121] In some embodiments, the downlink control signaling includes an identifier for the DCI format. The identifier field for the DCI format is 1 bit, which indicates an uplink or downlink BWP (bandwidth part) indication. The indication bit can be configured separately for each block, or shared by all blocks. In some embodiments, a value of all 0 data blocks indicates no BWP switching.

[0122] With appropriate indication of the BWP indication in the first set of PDCCH candidates, it is more advantageous for the UE to switch to a larger BWP for larger data packet reception or transmission, and use a smaller BWP to monitor PDCCH candidates. In addition, BWP switching associated with reference signals improves network performance.

[0123] Configuration information 3

[0124] Configuration information 3 includes information about the PDCCH monitoring timing of the second group of PDCCH candidates or PDCCH candidates. The information about the PDCCH monitoring timing includes at least one of the following: PDCCH monitoring period (periodicity), PDCCH monitoring duration (duration), PDCCH monitoring offset (offset), PDCCH monitoring mode in a time slot, search space activation, search space deactivation, CORESET activation or CORESET deactivation.

[0125] For example, when the data block indicates the first PDCCH detection period information, the second PDCCH detection period information, ..., or the Mth PDCCH detection period information, the PDCCH monitoring period of the second group of PDCCH candidates or the PDCCH candidates is multiplied by a 1 、a 2 , ..., or a M , where a 1 、a 2 ,……,a M is a positive number, i.e. a 1 、a 2 ,……,a M ≥1.

[0126] For example, when the data block indicates the first PDCCH monitoring duration information, the second PDCCH monitoring duration information, ..., or the Mth PDCCH monitoring duration information, the PDCCH monitoring duration of the second group of PDCCH candidates or PDCCH candidates is multiplied by b 1 、b 2, ..., or b M , where b 1 、b 2 ,……,b M is a positive number, i.e. b 1 、b 2 ,……,b M ≤1.

[0127] In some implementations, the indication of search space deactivation indicates that the UE is not required or expected to monitor the PDCCH in the deactivated search space. The indication of search space activation indicates that the UE is required or expected to monitor the PDCCH in the activated search space.

[0128] In some embodiments, the indication of search space deactivation indicates that the UE is not required or expected to monitor the corresponding PDCCH candidates of the deactivated search space. The indication of search space activation indicates that the UE is required or expected to monitor the corresponding PDCCH candidates of the activated search space.

[0129] For example, when the values ​​of the i-th block are all 0, this means that the PDCCH monitoring timing information does not change.

[0130] Using dynamic indication of PDCCH monitoring opportunities is more conducive to UE adapting to arriving services and reducing power consumption.

[0131] Configuration information 4

[0132] Configuration information 4 includes information about spatial information. The spatial information includes at least one of the following: the (maximum) number of MIMO layers, the (maximum) number of transport layers, the (maximum) number of antenna ports, the (maximum) number of antenna panels. For example, when the values ​​of the block are all 0, this means that one or more spatial information does not change. In some examples, the transport layer or MIMO layer is the layer onto which the transport block is mapped.

[0133] Dynamic indication using spatial information is more conducive to UE adapting to arriving services and reducing power consumption.

[0134] Configuration information 5

The time domain resource allocation includes at least one of the following: (minimum) K0, (minimum) K1, (minimum) K2, (minimum) A-CSI (non-periodic CSI) offset. For example, when the values ​​of the block are all 0, this means that one or more time domain resource allocations do not change.

[0136] By using the indication of the time domain resource allocation information, it is beneficial for the UE to know the information in advance for PDCCH decoding, which helps the UE to adapt to the arriving services and reduce power consumption.

[0137] Configuration information 6

[0138] Configuration information 6 includes an SRS request. In some embodiments, the control signaling includes an SRS request, or the control signaling is associated with an SRS request.

[0142] By using the indication of the CSI request, it is helpful for the UE or the network to know the information of the channel condition in advance, which helps to improve the performance.

[0143] Configuration information 8

[0144] Configuration information 8 includes beam or QCL information. In some embodiments, the beam information or antenna port quasi-co-location information of the second group of PDCCH candidates is associated with or determined by the first group of PDCCH candidates. For example, the beam information or antenna port quasi-co-location information of the second group of PDCCHs is indicated by the first group of PDCCH candidates. In another example, if the beam information or antenna port quasi-co-location information of the second group of PDCCHs overlap in certain domains, they can be associated with the first group of PDCCH candidates. The domain includes CORESET, search space, time resources, or frequency resources.

[0145] By using the indication of beam or QCL information, it is helpful for the UE or the network to know the information of the channel condition in advance, which helps to improve the performance.

In order to indicate the 8 functions listed above, 3 bits are required. For example, "000" indicates "wake up", "001" indicates PDCCH monitoring opportunity information, etc.

[0163] In some embodiments, the functional indication is designed to indicate the functionality of all blocks in the DCI or the functionality of one or more blocks in the DCI. When the functional indication indicates the functionality of all blocks in the DCI, all blocks in the DCI payload share the same functional indication. It can reduce the effective load and enhance performance. When the functional indication indicates the function of one or more blocks in the DCI, the blocks in the DCI payload can have separate indications. It provides more flexibility.

[0167] In some embodiments, the UE is indicated at least one of: i) the location in the DCI payload, or ii) the mapping rule. In some embodiments, the control signaling is specified by a PDCCH that is specific to a set of UEs. The UE needs to know how to interpret the DCI after PDCCH decoding, or the UE needs to know what information is indicated from the BS. Items i) to ii) will be discussed in detail below.

[0168] i) Position in the DCI payload. The UE is configured with information indicating which part of the DCI payload is used to transmit its information. The position in the DCI payload can be the starting position in the DCI payload, or the ending position in the DCI, or a block index. For example, assuming the payload is {b1, b2, b3, b4, b5, b6} (i.e. 6 bits in the DCI), the UE is configured with a starting position of 3, and a bit width of 2. In this case, bits b3 and b4 are used to transmit information to this particular UE. In another example, the DCI content is block #1, block #2, block #3, block #4, block #5. When the UE is configured with block index 3, block #3 is used to transmit information to this UE.

[0169] ii) Mapping rules. In this case, the UE is configured with different trigger states. The mapping rules are related to the number of UEs indicated by the same DCI and / or the number of trigger states for each UE. In this case, UE0 is indicated by a list of multiple trigger states {T1...TN} indicating UE1 to UEN.

[0170] Starting position

[0171] The starting position of a block is determined by higher layer parameters of one or more UEs that are configured with the block. The UEs configured with the same DCI payload are determined by higher layer parameters, service type, UE-ID, RNTI or UE assistance information.

[0172] Example 3

[0173] In some implementations, the control signaling may include:

[0174] i) Field-1: One of the configuration information 1 to 9 indications. In some implementations, Field-1 includes the configuration information-1 indication.

[0175] ii) Field - Other: Other configuration information indication

[0176] In some embodiments, the bit field carrying configuration information 1 is the first or last field in the DCI format bit field, or before / after a bit field with a predetermined size. If field-1 indicates that the UE configuration parameter has not changed, the value of the corresponding field-other is 0 or a padding bit. If field-1 indicates an entry into sleep indication or a reserved entry, the value of the corresponding field-other is 0 or a padding bit. Alternatively, if field-1 indicates that the UE configuration parameter has not changed, or an entry into sleep indication, or a reserved entry, the size of the bit field in field-other is W1. Otherwise, the size of the bit field in field-other is W2. W1 and W2 are non-negative integers, and W1 is less than W2.

[0177] Example 1: The information carried in the control signaling includes:

[0183] Block-M-1, block-M-2, ..., block-MN;----other functional indications, where M is a natural number.

[0184] Block-1-i and block-mj are associated, where i and j are positive numbers and 1≤m≤N. If the value of block-1-i is value-1, then block-mj is all zeros or padding bits. If the value of block-1-i is value-1, then the bit width of block-mj is W1. If the value of block-1-i is value-2, then the bit width of block-mj is W2. W1 and W2 are non-negative, and W1 is not greater than W2.

[0185] Example 2: The information carried in the control signaling includes:

[0186] Field-1:

[0187] ---L bits---Configuration information 1

[0188] Field - Other:

[0189] ---Block 1, Block 2, ..., Block B---Other configuration instructions

[0190] In this case, the UE is indicated by field-1 to enter sleep indication, and the corresponding block in field-others is zero or padding bits.

[0191] Information jointly coded in a block / DCI

[0192] In some embodiments, configuration information for a UE is jointly encoded in a data block. In some embodiments, configuration information for one or more UEs is jointly encoded in a DCI.

[0193] Indication of a subset of a UE set

[0194] In some embodiments, the control signaling includes an indication of a subset of the set of UEs. The control signaling is sent to one or more UEs. For example, when the control signaling is used for multiple UEs, when the subset field of the control signaling is value_1, the data block or control signaling is used to notify the configuration parameters of the subset of the set of UEs. When the subset field of the control signaling is value_2, the data block or control signaling is used to notify the configuration parameters of other subsets of the set of UEs.

[0195] In some embodiments, the control signaling includes a CSI request, or the control signaling is associated with a CSI request. In some embodiments, the SRS request is included in the control signaling. Alternatively, the control signaling is associated with the SRS request.

[0196] In some embodiments, the initial value of the DM-RS of the PS-PDCCH is related to the PS-RNTI.In some embodiments, the number of OFDM symbols occupied by the CORESET of the PDCCH with control signaling is 1 or 2.

[0197] In some embodiments, the REG mapping pattern of the first set of PDCCH candidates does not include interleaving.In some embodiments, the search space for the PDCCH with control signaling is a common search space.

[0198] In some embodiments, the data block field having an all-zero value indicates at least one of the following: 1) entering sleep indication; 2) configuration information 2 that is the same as a predefined timing; 3) configuration information 3 that is the same as a predefined timing; 4) configuration information 4 that is the same as a predefined timing; 5) configuration information 5 that is the same as a predefined timing; 6) configuration information 6 that is the same as a predefined timing; 7) configuration information 7 that is the same as a predefined timing; 8) configuration information 8 that is the same as a predefined timing; 9) configuration information 9 that is the same as a predefined timing. In some embodiments, the predefined timing is when the first group of PDCCH candidates is received, sent, or decoded.

[0199] In some implementations, the second group of PDCCH candidates cannot occupy predefined resources. The predefined resources may be configured by RRC for the first group of PDCCH candidates.

[0200] In some embodiments, the configuration of the first set of PDCCH candidates is per cell or carrier.

[0201] Timing of PDCCH with control signaling

[0202] There are two different offsets, including an offset between monitoring timings of the first group of PDCCH candidates provided by the corresponding search space and DRX on, and an offset between monitoring timings of the first group of PDCCH candidates and the second group of PDCCH candidates provided by the corresponding search space.

[0203] In some embodiments, the offset between the monitoring timing of the first set of PDCCH candidates provided by the corresponding search space and DRX on is associated with or determined by: i) UE capability, ii) PDSCH processing capability, iii) PUSCH preparation time, or iii) BWP switching time.

[0204] In some embodiments, the offset between the monitoring timing of the first set of PDCCH candidates and the monitoring timing of the second set of PDCCH candidates provided by the corresponding search space is associated with or determined by: i) UE capability, ii) PDSCH processing capability, iii) PUSCH preparation time, or iii) BWP switching time.

[0205] In some embodiments, the monitoring timing of the first group of PDCCH candidates or the search space of the first group of PDCCH candidates is periodic. In one example, the period of the monitoring timing of the first group of PDCCH candidates or the search space of the first group of PDCCH candidates is a multiple of the period of the DRX cycle. In another example, the period of the monitoring timing of the first group of PDCCH candidates or the search space of the first group of PDCCH candidates is less than the period of the DRX cycle. The period of the monitoring timing of the first group of PDCCH candidates or the search space of the first group of PDCCH candidates is a multiple of the maximum period of the search space of the second group of PDCCH candidates. The period of the monitoring timing of the first group of PDCCH candidates or the search space of the first group of PDCCH candidates can be a multiple of the minimum period of the search space of the second group of PDCCH candidates.

[0206] In some embodiments, the monitoring timing of the first group of PDCCH candidates may be after the inactivity timer starts. The monitoring timing of the first group of PDCCH candidates is different from the monitoring timing of the second group of PDCCH candidates in the time domain, and they are defined at different time timings. The first group of PDCCH candidates has a higher priority than the second group of PDCCH in mapping order. Therefore, if the timing of the first group of PDCCH conflicts or overlaps with the second group of PDCCH, the first group of PDCCH candidates is sent first.

[0207] In some embodiments, the number of blind decodings of the first group of PDCCH candidates is 1. In some embodiments, the beam information or antenna port quasi-co-location information of the second group of PDCCH candidates is associated with or determined by the first group of PDCCH candidates. For example, the beam information or antenna port quasi-co-location information of the second group of PDCCHs is indicated by the first group of PDCCH candidates. In another example, if the second group of PDCCHs and the first group of PDCCH candidates overlap in certain domains, the beam information or antenna port quasi-co-location information of the second group of PDCCHs is associated with the first group of PDCCH candidates. The domain includes a CORESET, a search space, a time resource, or a frequency resource.
