Abstract

An uplink transmission method and apparatus. The method includes: receiving by a terminal equipment indication information, wherein the indication information does not include an indication field used for indicating RB set, the indication information scheduling uplink transmission on an uplink bandwidth part including at least two resource block sets; and transmitting the uplink transmission on at least one predefined or preconfigured resource block set.

Claims (44)

1. An uplink transmission apparatus, comprising:

a receiver configured to receive indication information, the indication information scheduling uplink (UL) transmission on uplink bandwidth part (UL BWP) comprising at least two resource block (RB) sets; and

a transmitter configured to transmit the uplink transmission on a default RB set in the UL BWP,

wherein the information does not include an indication field used for indicating RB set allocated for the UL transmission,

the receiver further configured to receive configuration information for intra-cell guard band and/or RB set of an UL carrier and configuration information for the UL BWP on the carrier, and

the UL BWP includes integer number of RB sets of the carrier, the start RB of the UL BWP being same as the start RB of the RB set with lowest RB set index in the UL BWP and the end RB of the UL BWP being same as the end RB of the RB set with highest RB set index in the UL BWP.

2. The apparatus according to claim 1 , wherein the indication information comprises: downlink control information having a downlink control information format 0_0; wherein the downlink control information is scrambled by a C-RNTI or a CS-RNTI or an MCS-C-RNTI.

3. The apparatus according to claim 2 , wherein, the default RB set is:

an RB set in the UL BWP and corresponding to the frequency resource used for transmitting the indication information; or

an RB set with lowest RB set index in the UL BWP; or

an RB set with lowest frequency location in the UL BWP.

4. The apparatus according to claim 1 , wherein the indication information comprises: a random access response (RAR) in a random access procedure, or downlink control information having a downlink control information format 0_0 and scrambled by a TC-RNTI.

5. The apparatus according to claim 4 , wherein the default RB set is:

an RB set in the UL BWP and used for transmitting the PRACH corresponding to the UL transmission.

6. The apparatus according to claim 1 , wherein the UL transmission is a PUSCH transmission.

7. The apparatus according to claim 1 , wherein the configuration information for the intra-cell guard band and/or RB set of the UL carrier indicates no intra-cell guard band for the UL carrier.

8. An uplink transmission apparatus, comprising:

a receiver configured to receive indication information, the indication information scheduling uplink (UL) transmission on an uplink bandwidth part (UL BWP) comprising at least two resource block (RB) sets; and

a transmitter configured to transmit the uplink transmission on a default RB set in the UL BWP,

wherein the indication information does not include an indication field used for indicating RB set allocated for the UL transmission,

the receiver further configured to receive configuration information for intra-cell guard band and/or RB set of an UL carrier and configuration information for the UL BWP on the carrier, and

an RB set has an RB set index for the carrier and an RB set index for the UL BWP, RB sets being indexed in the order of frequency location and an RB set with lowest frequency location having lowest RB index.

9. An uplink transmission apparatus comprising:

a transmitter configured to transmit indication information, the indication information scheduling uplink (UL) transmission on an uplink bandwidth part (UL BWP) comprising at least two resource block (RB) sets; and

a receiver configured to receive the uplink transmission on a default RB set in the UL BWP,

wherein the indication information does not include an indication field used for indicating RB set allocated for the UL transmission,

the transmitter is further configured to transmit configuration information for intra-cell guard band and/or RB set UL carrier and configuration information for the UL BWP on the carrier, and

the UL BWP includes integer number of RB sets of the carrier, the start RB of the UL BWP being same as the start RB of the RB set with lowest RB set index in the UL BWP and the end RB of the UL BWP being same as the end RB of the RB set with highest RB set index in the UL BWP.

10. The apparatus according to claim 9 , wherein the indication information comprises: downlink control information having a downlink control information format 0_0; wherein the downlink control information is scrambled by a C-RNTI or a CS-RNTI or an MCS-C-RNTI.

11. The apparatus according to claim 10 , wherein, the default RB set is:

an RB set in the UL BWP and corresponding to the frequency resource used for transmitting the indication information; or

an RB set with lowest RB set index in the UL BWP; or

an RB set with lowest frequency location in the UL BWP.

12. The apparatus according to claim 9 , wherein the indication information comprises: a random access response (RAR) in a random access procedure, or downlink control information having a downlink control information format 0_0 and scrambled by a TC-RNTI.

13. The apparatus according to claim 12 , wherein the default RB set is:

an RB set in the UL BWP and used for transmitting the PRACH corresponding to the UL transmission.

14. The apparatus according to claim 9 , wherein the UL transmission is a PUSCH transmission.

15. The apparatus according to claim 9 , wherein the configuration information for the intra-cell guard band and/or RB set of the UL carrier indicates no intra-cell guard band for the UL carrier.

16. An uplink transmission apparatus, comprising:

a transmitter configured to transmit indication information, the indication information scheduling uplink (UL) transmission on an uplink bandwidth part (UL BWP) comprising at least two resource (RB) sets; and

a receiver configured to receive the uplink transmission on a default RB set in the UL BWP,

wherein the indication information does not include an indication field used for indicating RB set allocated for the UL transmission,

the transmitter is further configured to transmit configuration information for intra-cell guard band and/or RB set of an UL carrier and configuration information for the UL BWP on the carrier, and

an RB set has an RB set index for the carrier and an RB set index for the UL BWP, RB sets being indexed in the order of frequency location and an RB set with lowest frequency location having lowest RB index.
