Abstract

A subframe processing method and device are disclosed. A terminal can determine a special subframe in a non-contiguous secondary carrier according to a maximum continuous channel occupancy duration and a channel listening duration of the non-contiguous secondary carrier, and a channel occupancy start reference time point and/or a channel listening start reference time point of the non-contiguous secondary carrier that are obtained, where the special subframe includes all or some gap symbols occupied by the channel listening duration, use all symbols except the gap symbols in the special subframe as symbols that can be occupied by a PDCCH and/or a PDSCH, and correspondingly receive or decode the PDCCH and/or the PDSCH in the special subframe according to the symbols that can be occupied by the PDCCH and/or the PDSCH.

Claims4

Dependent claims

A network-side device, comprising a processor and a transmitter, wherein the processor is configured to:

transmit, via the transmitter, first carrier configuration information of a first carrier of a terminal to the terminal, the first carrier being on a common spectrum, wherein the first carrier configuration information comprises any one or more types of the following information:
system broadcast information of the first carrier, wherein the system broadcast information can indicate that the first carrier comprises a common channel, wherein the common channel comprises any one or more of a physical broadcast channel (PBCH), a primary synchronization channel (PSS), a secondary synchronization channel (SSS), or a reference signal,
first indication information, wherein the first indication information is used to indicate that the first carrier does not comprise a common channel, or
second indication information, wherein the second indication information is used to indicate that a common channel used in the first carrier is a common channel in an extended format;
and
wherein the processor is further configured to:
determine whether the first carrier comprises or does not comprise the common channel, so that:
in response to the common channel being not comprised in the first carrier, when receiving or decoding a PDCCH and/or a PDSCH in a subframe in the first carrier, the terminal may skip excluding, from symbols that can be occupied by the PDCCH and/or the PDSCH in the subframe, symbols occupied by the common channel;
and
in response to the common channel being comprised in the first carrier, determine whether the common channel in the extended format is used in the first carrier, so that:
in response to the common channel in the extended format being used in the first carrier, when receiving or decoding a PDCCH and/or a PDSCH in a subframe in the first carrier, the terminal may exclude, from symbols that can be occupied by the PDCCH and/or the PDSCH in the subframe, symbols occupied by the common channel in the extended format, or
in response to the common channel in the extended format being not used in the first carrier, when receiving or decoding a PDCCH and/or a PDSCH in a subframe in the first carrier, the terminal may skip excluding, from symbols that can be occupied by the PDCCH and/or the PDSCH in the subframe, symbols occupied by the common channel in the extended format.

9 more elements

A terminal, comprising a processor and a receiver, wherein the processor is configured to:

receive, via the receiver, first carrier configuration information delivered for a first carrier by a network-side device, the first carrier being on a common spectrum, wherein the first carrier configuration information comprises any one or more types of the following information:
system broadcast information of the first carrier, wherein the system broadcast information can indicate that the first carrier comprises a common channel, wherein the common channel comprises any one or more of a physical broadcast channel (PBCH), a primary synchronization channel (PSS), a secondary synchronization channel (SSS), or a reference signal,
first indication information, wherein the first indication information is used to indicate that the first carrier does not comprise a common channel, or
second indication information, wherein the second indication information is used to indicate that a common channel used in the first carrier is a common channel in an extended format;
and
wherein the processor is further configured to:
determine, according to the first carrier configuration information, whether the first carrier comprises or does not comprise the common channel, so that:
in response to the common channel being not comprised in the first carrier, when receiving or decoding a PDCCH and/or a PDSCH in a subframe in the first carrier, skip excluding, from symbols that can be occupied by the PDCCH and/or the PDSCH in the subframe, symbols occupied by the common channel;
and
in response to the common channel being comprised in the first carrier, determine, according to the first carrier configuration information, whether the common channel in the extended format is used in the first carrier, so that:
in response to the common channel in the extended format being used in the first carrier, when receiving or decoding a PDCCH and/or a PDSCH in a subframe in the first carrier, exclude, from symbols that can be occupied by the PDCCH and/or the PDSCH in the subframe, symbols occupied by the common channel in the extended format, or
in response to the common channel in the extended format being not used in the first carrier, when receiving or decoding a PDCCH and/or a PDSCH in a subframe in the first carrier, skip excluding, from symbols that can be occupied by the PDCCH and/or the PDSCH in the subframe, symbols occupied by the common channel in the extended format.
