Abstract
Some techniques described herein assist a user equipment with acquiring and/or reacquiring, from a base station, a dynamic list of channels to be used for frequency hopping when communicating over an unlicensed radio frequency spectrum band, thereby increasing communication reliability and promoting coexistence in the unlicensed radio frequency spectrum band. Some techniques described herein also assist the user equipment in obtaining the list of channels with low latency (e.g., shortly after the list has changed) and with low power consumption. Numerous other aspects are provided.
Claims30
A method of wireless communication, comprising:
- receiving, by a user equipment (UE), a master information block (MIB) that indicates a location of one or more system information blocks (SIBs),
- wherein the MIB includes a value that indicates whether a list of channels for frequency hopping in an unlicensed radio frequency spectrum band has changed from a previously indicated list;
- receiving, by the UE, the one or more SIBs based at least in part on the MIB, wherein the one or more SIBs indicate the list of channels,
- the list of channels being indicated by at least one of:
- a whitelist of channels that can be used for frequency hopping, or
- a blacklist of channels that cannot be used for frequency hopping;
- and
- communicating, by the UE, by frequency hopping on a plurality of channels, included in the list of channels, according to a frequency hopping pattern based at least in part on the indication in the one or more SIBs.
A method of wireless communication, comprising:
- transmitting, by a base station, a master information block (MIB) that indicates a location of one or more system information blocks (SIBs),
- wherein the MIB includes a value that indicates whether a list of channels permitted for use by a user equipment (UE) for frequency hopping in an unlicensed radio frequency spectrum band has changed from a previously indicated list;
- transmitting, by the base station, the one or more SIBS, wherein the one or more SIBs indicate the list of channels,
- the list of channels being indicated by at least one of:
- a whitelist of channels that can be used for frequency hopping, or
- a blacklist of channels that cannot be used for frequency hopping;
- and
- communicating, by the base station, with the UE using a plurality of channels included in the list of channels according to a frequency hopping pattern.
A user equipment (UE) for wireless communication, comprising:
- memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- receive a master information block (MIB) that indicates a location of one or more system information blocks (SIBs),
- wherein the MIB includes a value that indicates whether a list of channels for frequency hopping in an unlicensed radio frequency spectrum band has changed from a previously indicated list;
- receive the one or more SIBs based at least in part on the MIB, wherein the one or more SIBs indicate the list of channels,
- the list of channels being indicated by at least one of:
- a whitelist of channels that can be used for frequency hopping, or
- a blacklist of channels that cannot be used for frequency hopping;
- and
- communicate by frequency hopping on a plurality of channels, included in the list of channels, according to a frequency hopping pattern based at least in part on the indication in the one or more SIBs.
A base station for wireless communication, comprising:
- memory;
- and
- one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
- transmit a master information block (MIB) that indicates a location of one or more system information blocks (SIBs),
- wherein the MIB includes a value that indicates whether a list of channels permitted for use by a user equipment (UE) for frequency hopping in an unlicensed radio frequency spectrum band has changed from a previously indicated list;
- transmit the one or more SIBs, wherein the one or more SIBs indicate the list of channels,
- the list of channels being indicated by at least one of:
- a whitelist of channels that can be used for frequency hopping, or
- a blacklist of channels that cannot be used for frequency hopping;
- and
- communicate with the UE using a plurality of channels included in the list of channels according to a frequency hopping pattern.
