[0092] The skipped PDCCH monitoring occasion (MO) described in the embodiments of the present application can be understood as not monitoring PDCCH on the skipped PDCCH monitoring occasion.

[0093] The first duration described in the embodiments of the present application can also be referred to as a skipping duration.

[0094] In some embodiments, the indication information can be PDCCH monitoring skipping indication.

[0095] In some embodiments, the skipped PDCCH monitoring occasion indicated by the indication information is a PDCCH monitoring occasion corresponding to a first type of search space (SS);

[0096] The first type of search space includes at least one of the following:

[0097] Type 0 common search space (CSS) or type 0A CSS;

[0098] Type 1 CSS or type 2 CSS;

[0099] Type 3 CSS;

[0100] User-specific search space (USS).

[0101] In some embodiments, the indication information is carried by terminal-specific signaling or common signaling;

[0102] The common signaling includes at least one of the following:

[0103] System information;

[0104] PDCCH scheduling system information;

[0105] Paging message;

[0106] PDCCH scheduling the paging message;

[0107] Random access response information;

[0108] PDCCH scheduling the random access response information;

[0109] PDCCH carrying paging early indication (PEI) information;

[0110] Group common channel (PDCCH).

[0111] In some embodiments, the first duration is based on a first reference time as the starting time;

[0112] Wherein, the first reference time is the moment or time unit in which the indication information is located, or the first reference time is the moment or time unit in which the feedback corresponding to the indication information is located, or the first reference time is the moment or time unit after at least one time unit has passed since the indication information.

[0113] Optionally, the at least one time unit can be configured by the network side, or the at least one time unit can be agreed upon by the protocol.

[0114] Optionally, the first reference time may also be agreed upon by an agreement, and this application does not limit this.

[0115] The time-domain unit described in the embodiments of this application includes at least one of the following:

[0116] Symbol, time slot, subframe, frame, millisecond, microsecond, second, minute, specific period value.

[0117] Optionally, the specific period value can be a discontinuous reception (DRX) period value, or the specific period value can be a period value of the search space, or the specific period value can be the maximum period value of the search space, or the specific period value can be the minimum period value of the search space.

[0118] In some embodiments, the indication information is used to indicate the PDCCH listening time within the first duration among the PDCCH listening times configured by the configuration information to be skipped, and the indication information includes L indication fields; or, the indication information is used to indicate the PDCCH listening time within the first duration among the PDCCH listening times configured by the configuration information not to be skipped, and the indication information includes L indication fields.

[0119] Wherein, the L indicator fields are used to indicate the number of L types of time domain units to be skipped, where L is a positive integer greater than or equal to 2; the first duration is the sum of the durations corresponding to the L types of time domain units respectively.

[0120] In this embodiment, the network-side device can indicate the number of L types of time domain units to be skipped through L indication fields. The network-side device designs the number of skips for each of the L types of time domain units, thereby improving the flexibility and accuracy of skipping PDCCH monitoring timing. The network-side device can instruct the terminal to skip PDCCH monitoring in a more limited manner based on actual needs, avoiding invalid PDCCH monitoring and thus achieving terminal energy saving.

[0121] Specifically, an i-th indication field in the L indication fields can be used to indicate a number of i-th time domain units, 0≤i≤L.

[0122] For example, a time length corresponding to the i-th time domain unit is a product of the number of i-th time domain units indicated by the i-th indication field and the i-th time domain unit.

[0123] For example, the indication information includes two indication fields (e.g., L=2), a first indication field is used to indicate a number of skipped frames, and a second indication field is used to indicate a number of skipped slots. For a subcarrier spacing (SCS) of 30KHz, if the first indication field indicates that the number of skipped frames is 2 (e.g., 2 frames, corresponding to 40 slots), and the second indication field indicates that the number of skipped slots is 5, then the first time length is 2*frame+5*slot=45 slots. That is, the indication information is used to indicate that the PDCCH monitoring occasion located within the first time length (45 slots) in the PDCCH monitoring occasion configured by the configuration information is skipped; or the indication information is used to indicate that the PDCCH monitoring occasion located within the first time length (45 slots) in the PDCCH monitoring occasion configured by the configuration information is not skipped.

[0124] For example, the indication information includes two indication fields (e.g., L=2), a first indication field is used to indicate a number of skipped subframes, and a second indication field is used to indicate a number of skipped specific periodic values.

[0125] For example, the indication information includes two indication fields (e.g., L=2), a first indication field is used to indicate a number of skipped subframes, and a second indication field is used to indicate a number of skipped slots.

[0126] For example, the indication information includes three indication fields (e.g., L=3), a first indication field is used to indicate a number of skipped frames, a second indication field is used to indicate a number of skipped slots, and a third indication field is used to indicate a number of skipped symbols.

[0127] For example, the indication information includes three indication fields (e.g., L=3), a first indication field is used to indicate a number of skipped seconds, a second indication field is used to indicate a number of skipped milliseconds, and a third indication field is used to indicate a number of skipped microseconds.

[0128] In some embodiments, the indication information further includes a first indication field; wherein the first indication field is used to indicate the L types of time-domain units; or, the first indication field is used to indicate the combination index corresponding to the L types of time-domain units in at least two combinations of time-domain units, each of the at least two combinations of time-domain units including L types of time-domain units. In other words, the indication information includes the first indication field and the L indication fields.

[0129] In this embodiment, the network-side device can indicate L types of time-domain units through the first indication field, so that the terminal can determine the specific object of the number of PDCCH monitoring skipped indicated by the L indication fields.

[0130] Optionally, the combination of the at least two time-domain units can be configured by the network side, or the combination of the at least two time-domain units can be agreed upon by the protocol.

[0131] In some embodiments, the L types of time-domain units may be agreed upon by a protocol, or the L types of time-domain units may be pre-configured by the network side.

[0132] In some embodiments, when at least one of the L indication fields takes a first value, the indication information is used to indicate a PDCCH listening opportunity within the first duration that is skipped from the PDCCH listening opportunities configured by the configuration information; and / or,

[0133] When all L indication fields have the second value, the indication information is used to indicate the PDCCH listening time within the first duration among the PDCCH listening times configured by the configuration information that are not skipped.

[0134] In this embodiment, the network-side device can indicate, based on the values ​​of L indication fields, whether to skip the PDCCH monitoring time within the first duration configured in the configuration information or not skip the PDCCH monitoring time within the first duration configured in the configuration information, thereby improving the flexibility of indicating PDCCH monitoring skipping.

[0135] Optionally, the first value is 1 and the second value is 0; or, the first value is 0 and the second value is 1.

[0136] In some embodiments, the size of the i-th indicator field among the L indicator fields is log2(M) i +a i Rounding up to the nearest integer;

[0137] Where i is an integer, 0≤i≤L, M i M represents the number of candidate values ​​for the i-th time-domain unit corresponding to the i-th indicator domain.i is a positive integer, a i represents a constant corresponding to the i-th indication field.

[0138] For example, the i-th time domain unit is a time slot, and the candidate values can be time slot 0, time slot 5, and time slot 10. In this case, M i = 3.

[0139] For example, the i-th time domain unit is a symbol, and the candidate values can be symbol 2, symbol 4, symbol 6, and symbol 8. In this case, M i = 4.

[0140] For example, a i = 0, 1, or 2.

[0141] Alternatively, the candidate values of the i-th time domain unit can be determined by a protocol, or the candidate values of the i-th time domain unit can be configured by a network side.

[0142] For example, the indication information includes two indication fields. If the first indication field has two codepoints of 0 and infinite, in this case, a1 = 2. If the second indication field has only one codepoint of 0, in this case, a2 = 1.

[0143] For example, for the i-th indication field, if 0 and infinite are both candidate values, a i = 0.

[0144] In some embodiments, the indication information is used to indicate skipping of PDCCH monitoring occasions located within the first time length among the PDCCH monitoring occasions configured by the configuration information, and the indication information includes a second indication field and a third indication field. Alternatively, the indication information is used to indicate not skipping of PDCCH monitoring occasions located within the first time length among the PDCCH monitoring occasions configured by the configuration information, and the indication information includes a second indication field and a third indication field.

[0145] The second indication field is used to indicate a first time domain unit, and the third indication field is used to indicate a number of the first time domain units to be skipped.

[0146] The first time length is a product of the first time domain unit and the number of the first time domain units.

[0147] In the embodiment, the network-side device can indicate the first time domain unit through the second indication field, and indicate the number of the first time domain units to be skipped through the third indication field, thereby improving the flexibility and accuracy of the PDCCH monitoring occasion skipping, and the network-side device can more specifically indicate the terminal to skip the PDCCH monitoring based on the actual demand, so as to avoid the invalid PDCCH monitoring and achieve the terminal energy saving.

[0148] Optionally, the first time domain unit comprises one of the following:

[0149] Symbol, slot, subframe, frame, millisecond, microsecond, second, minute, and specific period value.

[0150] For example, the indication information comprises a second indication field and a third indication field, wherein the second indication field is used to indicate the time granularity to be skipped (the candidate value is frame or slot), and the third indication field is used to indicate the number of the time granularity to be skipped. Assuming that the candidate value of the time granularity of the second indication field is frame, and the third indication field is 3, then for 30KHz SCS, 60 slots are indicated to be skipped, and the first time length is 60 slots.

[0151] In some embodiments, in a case where the third indication field takes a third value, the indication information is used to indicate that the PDCCH monitoring occasions located in the first time length in the PDCCH monitoring occasions configured by the configuration information are to be skipped; and / or in a case where the third indication field takes a fourth value, the indication information is used to indicate that the PDCCH monitoring occasions located in the first time length in the PDCCH monitoring occasions configured by the configuration information are not to be skipped.

[0152] In the embodiment, the network-side device can indicate that the PDCCH monitoring occasions located in the first time length in the PDCCH monitoring occasions configured by the configuration information are to be skipped or not to be skipped based on the value of the third indication field, thereby improving the flexibility of indicating the PDCCH monitoring skipping.

[0153] Optionally, the third value is 1, and the fourth value is 0; or the third value is 0, and the fourth value is 1.

[0154] For example, the second indication field takes a symbol value, and the third indication field takes a specific codepoint (for example, 00), then the third indication field indicates that the number of the symbols to be skipped is R, in this case, R PDCCH MOs are skipped.

[0155] In some embodiments, a size of the second indication field is an upper limit of log2(W+b), where W represents a number of candidate values of the first time domain unit, W is a positive integer, and b is a constant. Optionally, b=0, 1 or 2.

[0156] Optionally, the candidate values of the first time domain unit can be agreed by a protocol, or the candidate values of the first time domain unit can be configured by a network side.

[0157] For example, the candidate values of the first time domain unit are time slots or symbols, in which case W=2.

[0158] For example, the candidate values of the first time domain unit are subframes, time slots or symbols, in which case W=3.
