Abstract
The present invention discloses a data transmission method and apparatus, and a user equipment. The method includes: classifying, by using a transmission time interval TTI as a classification basis, TTIs on a carrier in a cell into a time division multiplexing TDM TTI and a code division multiplexing CDM TTI; and sending, to a user equipment UE, control information carrying a classified result, so as to instruct the UE to send uplink data according to the classified result and a data scheduling type of the UE in the TDM TTI or the CDM. By using the foregoing technical solution, a data transmission resource can be well saved and scheduling flexibility can be improved.
Claims11
A data transmission method, comprising:
- classifying, by using a transmission time interval (TTI) as a classification basis, TTIs on a carrier in a cell into a time division multiplexing (TDM) TTI and a code division multiplexing (CDM) TTI;
- and
- sending, to a user equipment (UE) through an enhanced dedicated channel absolute grant channel, control information carrying the classified result, so as to instruct the UE to send uplink data according to the classified result and a data scheduling type of the UE in the TDM TTI or the CDM TTI,
- wherein the classified result comprises a common process number that is used to identify each TTI obtained by means of the classification, and a bit that is in a one-to-one correspondence with each common process number,
- wherein different bits are respectively used to identify the TDM TTI and the CDM TTI that are obtained by means of the classification,
- wherein the common process number equals the remainder of five times a set common connection frame number plus a common subframe number, divided by a hybrid automatic repeat round trip time, and
- wherein the common subframe number is subordinate to a common connection frame and is used to identify a different TTI.
