Abstract

A resource transmission method, a resource transmission apparatus, and a communications device. The resource transmission method is applied to a terminal and includes: obtaining first information, where the first information includes at least one of configuration information and scheduling information for uplink transmission; and determining an uplink transmission mode based on the first information, where the uplink transmission mode supports frequency hopping on an unlicensed frequency band, or the uplink transmission mode does not support frequency hopping on the unlicensed frequency band.

First claim

What is claimed is:

1 . A resource transmission method, applied to a terminal and comprising:
obtaining first information, wherein the first information comprises at least one of configuration information and scheduling information for uplink transmission; and determining an uplink transmission mode based on the first information, wherein the uplink transmission mode supports frequency hopping on an unlicensed frequency band, wherein in a case that the scheduling information indicates that the uplink transmission is a dynamic grant based PUSCH, and that a first preset condition is satisfied, the uplink transmission mode supports intra-slot frequency hopping on the unlicensed frequency band, and wherein the first preset condition comprises at least one of the following: the terminal being not configured with a PUSCH aggregation factor; and scheduling of at least two PUSCHs being permitted in uplink scheduling, and time-domain resources for the at least two PUSCHs scheduled being located in at least one slot.

2 . The method according to claim 1 , wherein the first information satisfies any one of the following: being configured by a network-side device; and being specified by a protocol.

3 . The method according to claim 1 , wherein in a case that the scheduling information indicates that the uplink transmission is a configured grant based physical uplink shared channel PUSCH and that a number of candidate PUSCHs in a slot is 1, the uplink transmission mode supports intra-slot frequency hopping on the unlicensed frequency band.

4 . The method according to claim 1 , wherein in a case that the scheduling information indicates that the uplink transmission is a configured grant based PUSCH, that a number of candidate PUSCHs in a slot is 1, and that a number of consecutive slots is greater than 1, the uplink transmission mode supports intra-slot frequency hopping and/or inter-slot frequency hopping on the unlicensed frequency band.

5 . The method according to claim 1 , wherein
the first preset condition further comprises at least one of the following: a number of repetitions of the dynamic grant based PUSCH being 1; and scheduling of one PUSCH being permitted in uplink scheduling.

6 . The method according to claim 1 , wherein in a case that the scheduling information indicates that the uplink transmission is a dynamic grant based PUSCH and that a second preset condition is satisfied, the uplink transmission mode supports intra-slot frequency hopping and/or inter-slot frequency hopping on the unlicensed frequency band, wherein
the second preset condition comprises at least one of the following: the terminal being configured with a PUSCH aggregation factor; a number of repetitions of the dynamic grant based PUSCH being greater than 1; scheduling of one PUSCH being permitted in uplink scheduling; and scheduling of at least two PUSCHs being permitted in uplink scheduling, and time-domain resources for the at least two PUSCHs scheduled being located in at least one slot; wherein in a case that scheduling of at least two PUSCHs is permitted in uplink scheduling, and that time-domain resources for the at least two PUSCHs scheduled are located in at least one slot, the terminal transmits only PUSCH(s) in a first slot.

7 . The method according to claim 1 , wherein in a case that the uplink transmission mode supports frequency hopping on the unlicensed frequency band, the uplink transmission mode supports intra-PUSCH frequency hopping.

8 . The method according to claim 7 , wherein the uplink transmission mode further supports at least one of the following frequency hopping patterns:
intra-slot frequency hopping for at least two PUSCHs; consecutive inter-PUSCH frequency hopping; and inter-slot frequency hopping.

9 . The method according to claim 7 , wherein in the frequency hopping patterns, the terminal transmits same or different PUSCHs in one dynamic scheduling.

10 . A resource transmission method, applied to a network-side device and comprising:
transmitting first information to a terminal; wherein the first information comprises at least one of configuration information and scheduling information for uplink transmission, the first information is used to indicate an uplink transmission mode for the terminal, and the uplink transmission mode supports frequency hopping on an unlicensed frequency band, wherein in a case that the scheduling information indicates that the uplink transmission is a dynamic grant based PUSCH, and that a first preset condition is satisfied, the uplink transmission mode supports intra-slot frequency hopping on the unlicensed frequency band, and wherein the first preset condition comprises at least one of the following: the terminal being not configured with a PUSCH aggregation factor; and scheduling of at least two PUSCHs being permitted in uplink scheduling, and time-domain resources for the at least two PUSCHs scheduled being located in at least one slot.

11 . The method according to claim 10 , wherein in a case that the scheduling information indicates that the uplink transmission is a configured grant based physical uplink shared channel PUSCH and that a number of candidate PUSCHs in a slot is 1, the uplink transmission mode supports intra-slot frequency hopping on the unlicensed frequency band.

12 . The method according to claim 10 , wherein in a case that the scheduling information indicates that the uplink transmission is a configured grant based PUSCH, that a number of candidate PUSCHs in a slot is 1, and that a number of consecutive slots is greater than 1, the uplink transmission mode supports intra-slot frequency hopping and/or inter-slot frequency hopping on the unlicensed frequency band.

13 . The method according to claim 10 , wherein
the first preset condition further comprises at least one of the following: a number of repetitions of the dynamic grant based PUSCH being 1; and scheduling of one PUSCH being permitted in uplink scheduling.

14 . The method according to claim 10 , wherein in a case that the scheduling information indicates that the uplink transmission is a dynamic grant based PUSCH and that a second preset condition is satisfied, the uplink transmission mode supports intra-slot frequency hopping and/or inter-slot frequency hopping on the unlicensed frequency band, wherein
the second preset condition comprises at least one of the following: the terminal being configured with a PUSCH aggregation factor; a number of repetitions of the dynamic grant based PUSCH being greater than 1; scheduling of one PUSCH being permitted in uplink scheduling; and scheduling of at least two PUSCHs being permitted in uplink scheduling, and time-domain resources for the at least two PUSCHs scheduled being located in at least one slot.

15 . The method according to claim 14 , wherein in a case that scheduling of at least two PUSCHs is permitted in uplink scheduling, and that time-domain resources for the at least two PUSCHs scheduled are located in at least one slot, the first information is used to indicate that the terminal transmits only PUSCH(s) in a first slot.

16 . The method according to claim 10 , wherein in a case that the uplink transmission mode supports frequency hopping on the unlicensed frequency band, the uplink transmission mode supports intra-PUSCH frequency hopping.

17 . The method according to claim 16 , wherein the uplink transmission mode further supports at least one of the following frequency hopping patterns:
intra-slot frequency hopping for at least two PUSCHs; consecutiv
