Abstract

A terminal (e.g. user equipment (UE)) receives signal sending indication information that is sent by an access network device for an uplink subframe, where the signal sending indication information is used to instruct the terminal to send a sounding reference signal SRS in a first symbol of the uplink subframe, and/or used to instruct the terminal to send a PUSCH in a symbol that is included in a second symbol set of the uplink subframe. The terminal sends an SRS and/or a PUSCH in the uplink subframe based on the signal sending indication information.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a terminal, a physical control channel from an access network device, wherein the physical control channel comprises signal sending indication information indicating whether a symbol set for a physical uplink shared channel (PUSCH) in an uplink subframe includes a last symbol of the uplink subframe and whether the symbol set for the PUSCH includes a first symbol of the uplink subframe;
determining, by the terminal, the symbol set for the PUSCH according to the signal sending indication information; and
sending, by the terminal, the PUSCH on the symbol set in the uplink subframe;
wherein the symbol set is one of candidate symbol sets comprised in a candidate symbol set group, the candidate symbol set group comprises the following candidate symbol sets:
the 2 nd symbol to the last but one symbol of the uplink subframe;
the 1 st symbol to the last but one symbol of the uplink subframe;
the 2 nd symbol to the last symbol of the uplink subframe; and
all symbols of the uplink subframe.

2. The method according to claim 1 , wherein the physical control channel is a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH).

3. The method according to claim 1 , wherein each candidate symbol set in the candidate symbol set group comprises 14, 13, 12, or 11 consecutive symbols.

4. An apparatus, comprising:
a processor; and
a storage medium comprising executable instructions that, when executed by the processor, cause the apparatus to:
receive a physical control channel from an access network device, wherein the physical control channel comprises signal sending indication information indicating whether a symbol set for a physical uplink shared channel (PUSCH) in an uplink subframe includes a last symbol of the uplink subframe and whether the symbol set for the PUSCH includes a first symbol of the uplink subframe;
determine the symbol set for the PUSCH according to the signal sending indication information; and
send the PUSCH on the symbol set in the uplink subframe;
wherein the symbol set is one of candidate symbol sets comprised in a candidate symbol set group, the candidate symbol set group comprises the following candidate symbol sets:
the 2 nd symbol to the last but one symbol of the uplink subframe;
the 1 st symbol to the last but one symbol of the uplink subframe;
the 2 nd symbol to the last symbol of the uplink subframe; and
all symbols of the uplink subframe.

5. The apparatus according to claim 4 , wherein the physical control channel is a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH).

6. The apparatus according to claim 4 , wherein each candidate symbol set in the candidate symbol set group comprises 14, 13, 12, or 11 consecutive symbols.

7. A non-transitory computer readable storage medium, comprising computer program codes which when executed by a computer processor cause the computer processor to:
receive a physical control channel from an access network device, wherein the physical control channel comprises signal sending indication information indicating whether a symbol set for a physical uplink shared channel (PUSCH) in an uplink subframe includes a last symbol of the uplink subframe and whether the symbol set for the PUSCH includes a first symbol of the uplink subframe;
determine the symbol set for the PUSCH according to the signal sending indication information; and
send the PUSCH on the symbol set in the uplink subframe;
wherein the symbol set is one of candidate symbol sets comprised in a candidate symbol set group, the candidate symbol set group comprises the following candidate symbol sets:
the 2 nd symbol to the last but one symbol of the uplink subframe;
the 1 st symbol to the last but one symbol of the uplink subframe;
the 2 nd symbol to the last symbol of the uplink subframe; and
all symbols of the uplink subframe.

8. The non-transitory computer readable storage medium according to claim 7 , wherein the physical control channel is a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH).

9. The non-transitory computer readable storage medium according to claim 7 , wherein every candidate symbol set in the candidate symbol set group comprises 14, 13, 12, or 11 consecutive symbols.
