Abstract
Embodiments of the present invention provide data sending and receiving methods and devices. The data sending method includes: sending a first data transmit power control (TPC) command and first service data to first user equipment (UE) in a first sending time period, so that the first UE performs inner loop power control according to the first data TPC command and receives the first service data; and sending a second preamble transmit power control TPC command to a second UE in a second pre-configured time period, so that the second UE establishes inner loop power control loop according to the second preamble transmit power control TPC command and receives second service data in a second sending time period.
Claims20
A data sending method, comprising:
- sending a first data transmit power control (TPC) command and first service data to first user equipment (UE) in a first sending time period, so that the first UE performs inner loop power control according to the first data TPC command and receives the first service data;
- and
- sending a second preamble TPC command to a second UE in a second pre-configured time period, so that the second UE establishes inner loop power control loop according to the second preamble TPC command and receives second service data in a second sending time period, wherein the first service data and the second service data are sent on a same code channel in a time division multiplexing manner, the first data TPC command and the second preamble TPC command are sent on different channels, and an overlap time period exists between the first sending time period and the second pre-configured time period.
A data receiving method, comprising:
- receiving, by user equipment (UE), a preamble transmit power control (TPC) command that is sent in a pre-configured time period by a base station, and establishing inner loop power control loop according to the preamble TPC command;
- receiving, by the UE, a data TPC command that is sent in a sending time period by the base station, and performing inner loop power control according to the data TPC command;
- and
- receiving, by the UE according to the inner loop power control, service data that is sent in the sending time period by the base station, wherein the service data sent by the base station to the UE and service data sent by the base station to another UE are sent on a same code channel in a time division multiplexing manner, and the pre-configured time period overlaps a sending time period of the other UE.
A base station, comprising:
- a first time period sending module, configured to send a first data transmit power control (TPC) command and first service data to first user equipment (UE) in a first sending time period, so that the first UE performs inner loop power control according to the first data TPC command and receives the first service data;
- and
- a second pre-configured time period sending module, configured to send a second preamble TPC command to a second UE in a second pre-configured time period, so that the second UE establishes inner loop power control loop according to the second preamble TPC command and receives second service data in a second sending time period, wherein the first service data and the second service data are sent on a same code channel in a time division multiplexing manner, the first data TPC command and the second preamble TPC command are sent on different channels, and an overlap time period exists between the first sending time period and the second pre-configured time period.
User equipment (UE), comprising:
- a pre-configured time period receiving module, configured to receive a preamble transmit power control (TPC) command that is sent in a pre-configured time period by a base station, and establish inner loop power control loop according to the preamble TPC command;
- a first time period receiving module, configured to receive a data TPC command that is sent in a sending time period by the base station, and perform inner loop power control according to the data TPC command;
- and
- a second time period receiving module, configured to receive, according to the inner loop power control, service data that is sent in the sending time period by the base station, wherein the service data sent by the base station to the UE and service data sent by the base station to another UE are sent on a same code channel in a time division multiplexing manner, and the pre-configured time period overlaps a sending time period of the other UE.
