Abstract

Embodiments of the present application provides signal transmission method and apparatus for discontinuous reception, the signal transmission method includes: measuring, by a terminal device, a signal received by each of at least one downlink receiving beam and transmitted by a network device, where the number of the at least one downlink receiving beam is less than the number of downlink receiving beams formed by the terminal device and the network device by means of beamforming; determining, by the terminal device, a target downlink receiving beam from the at least one downlink receiving beam according to a result of the measurement; reporting, by the terminal device, the target downlink receiving beam to the network device, and receiving, by the terminal device, through the target downlink receiving beam, a physical downlink control channel PDCCH transmitted by the network device.

Dependent claims

A data transmission method for discontinuous reception, comprising:

measuring, by a terminal device, a first signal received by each of at least one downlink receiving beam and transmitted by a network device, wherein a number of the at least one downlink receiving beam is less than a number of downlink receiving beams formed by the terminal device and the network device by means of beamforming;
determining, by the terminal device, a target downlink receiving beam from the at least one downlink receiving beam according to a result of the measurement;
reporting, by the terminal device, the target downlink receiving beam to the network device, and receiving, by the terminal device, through the target downlink receiving beam, a physical downlink control channel (PDCCH) transmitted by the network device,
wherein before the measuring, by a terminal device, a first signal received by each of at least one downlink receiving beam and transmitted by a network device, the method further comprises:
determining, by the terminal device, a first measurement timer, wherein a length of the first measurement timer is less than a duration in which the terminal device is in an activation state of an active discontinuous reception (Active DRX), and the terminal device also receive and decode the PDCCH during the activation state of the Active DRX, wherein the duration in which the terminal device is in the activation state of the Active DRX is a length of an on-duration timer of the terminal device;
and
the measuring, by a terminal device, a first signal received by each of at least one downlink receiving beam and transmitted by a network device comprises:
starting, by the terminal device, the first measurement timer, and measuring, by the terminal device, the first signal received by a first downlink receiving beam;
if the first measurement timer does not expire, continuing, by the terminal device, measuring the first signal received by a second downlink receiving beam;
and
when the first measurement timer expires, stopping, by the terminal device, the measurement.
