Abstract

The present disclosure relates to communication methods and apparatuses. In one example method, configuration information is received from a network device, where the configuration information is used to configure a control-resource set and M search spaces associated with the control-resource set, and each search space in the M search spaces and the control-resource set are used to transmit a first physical downlink control channel (PDCCH) once. Further, the first PDCCH may be monitored on time-frequency resources corresponding to the control-resource set and the M search spaces. M is an integer greater than 1.

Claims (46)

1. A communication method, wherein the method comprises:

receiving configuration information from a network device, wherein the configuration information is used to configure M control-resource sets and M search spaces, M is an integer greater than 1, the M control-resource sets are in one-to-one association with the M search spaces, and each search space in the M search spaces and an associated control-resource set in the M control-resource sets are used to transmit a first physical downlink control channel (PDCCH) once;

receiving first indication information from the network device, wherein the first indication information indicates that the M search spaces have an association relationship, and the M search spaces are used to transmit the first PDCCH M times; and

monitoring the first PDCCH on time-frequency resources corresponding to the M control-resource sets and the M search spaces.

2. The method according to claim 1 , wherein the M search spaces satisfy one or more of the following:

detection periods of the M search spaces are the same;

slot offsets of the M search spaces are the same; and

duration of the M search spaces is the same.

3. The method according to claim 1 , wherein the M control-resource sets satisfy:

first parameters of the M control-resource sets are the same, wherein a first parameter of a first control-resource set in the M control-resource sets indicates whether a PDCCH corresponding to the first control-resource set comprises a transmission configuration indication (TCI) field.

4. The method according to claim 1 , wherein the M search spaces comprise a first search space, configuration information of the first search space comprises the first indication information, and the first indication information comprises identifier information of another search space other than the first search space in the M search spaces.

5. A communication method, wherein the method comprises:

first parameters of the M control-resource sets are the same, wherein a first parameter of a first control-resource set in the M control-resource sets indicates whether a PDCCH corresponding to the first control-resource set comprises a transmission configuration indication (TCI) field.

12. The communications apparatus according to claim 9 , wherein the M search spaces comprise a first search space, configuration information of the first search space comprises the first indication information, and the first indication information comprises identifier information of another search space other than the first search space in the M search spaces.

13. A communications apparatus, comprising:

at least one processor and a communication interface receiving programming instructions, wherein the at least one processor executes the programming instructions to cause the apparatus to:

send configuration information to a terminal device, wherein the configuration information is used to configure M control-resource sets and M search spaces, M is an integer greater than 1, the M control-resource sets are in one-to-one association with the M search spaces, and each search space in the M search spaces and an associated control-resource set in the M control-resource sets are used to transmit a first physical downlink control channel (PDCCH) once;

send first indication information to the terminal device, wherein the first indication information indicates that the M search spaces have an association relationship, and the M search spaces are used to transmit the first PDCCH M times; and

transmit the first PDCCH M times on time-frequency resources corresponding to the M control-resource sets and the M search spaces.

14. The communications apparatus according to claim 13 , wherein the M search spaces satisfy one or more of the following:
