Abstract

An embodiment method for paging notification includes hashing an identity of a UE to determine a paging frame in which a page is to be sent to the UE and to determine an index of an entry in a bitmap, setting the entry at the index in the bitmap to a value indicating whether a page message associated with a paging group to which the UE belongs is transmitted in a current paging cycle, and transmitting the bitmap in each of a plurality of beamformed beams, wherein the beams are transmitted in a sweeping pattern such that at least one beam is transmitted in every portion of a coverage area of a component transmitting the beams and such that each of the beams is transmitted at least once during the paging frame.

First claim

1 . A method for paging notification comprising:
hashing an identity of a user equipment (UE) to determine a paging frame in which a page is to be sent to the UE and to determine an index of an entry in a bitmap; setting the entry at the index in the bitmap to a value indicating whether a page message associated with a paging group to which the UE belongs is transmitted in a current paging cycle; and transmitting the bitmap in each of a plurality of beamformed beams, wherein the beams are transmitted in a sweeping pattern such that at least one beam is transmitted in every portion of a coverage area of a component transmitting the beams and such that each of the beams is transmitted at least once during the paging frame.

2 . The method of claim 1 , wherein a number of entries in the bitmap is equal to a number of paging groups in the paging frame.

3 . The method of claim 1 , wherein at least one paging transmission time interval (TTI) is transmitted in each of the beams, and wherein the bitmap is transmitted in each paging TTI.

4 . The method of claim 3 , wherein a number of paging TTIs transmitted is part of a paging configuration.

5 . The method of claim 1 , wherein the hashing further determines a paging TTI within a plurality of paging TTIs in which the bitmap is to be transmitted.

6 . A method for paging monitoring comprising:
hashing an identity of a user equipment (UE) to determine a paging frame in which a page is to be sent to the UE and to determine a position of an indicator in a bitmap to be sent to the UE, wherein a value of the indicator indicates whether a page message associated with a paging group to which the UE belongs is transmitted in a current paging cycle; identifying, by the UE, a preferred downlink beamformed beam from a plurality of beams within the paging frame in which the UE is capable of receiving a downlink transmission; monitoring the preferred downlink beam during the paging frame to receive the bitmap; and when the value of the indicator indicates that the page message is transmitted in the current paging cycle, receiving and decoding the page message to determine whether the UE is being paged.

7 . The method of claim 6 , wherein a number of entries in the bitmap is equal to a number of paging groups in the paging frame.

8 . The method of claim 6 , wherein a number of paging transmission time intervals (TTIs) the UE is specified to receive is variable.

9 . The method of claim 6 , wherein the UE listens to enough paging TTIs to receive the bitmap with at least a threshold reliability.

10 . The method of claim 6 , wherein the hashing further determines a paging TI within a plurality of paging TTIs in which the bitmap is to be received.

11 . A transmit/receive point comprising:
a processor; and a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
hash an identity of a user equipment (UE) to determine a paging frame in which a page is to be sent to the UE and to determine an index of an entry in a bitmap;
set the entry at the index in the bitmap to a value indicating whether a page message associated with a paging group to which the UE belongs is transmitted in a current paging cycle; and
transmit the bitmap in each of a plurality of beamformed beams, wherein the beams are transmitted in a sweeping pattern such that at least one beam is transmitted in every portion of a coverage area of a component transmitting the beams and such that each of the beams is transmitted at least once during the paging frame.

12 . The transmit/receive point of claim 11 , wherein a number of entries in the bitmap is equal to a number of paging groups in the paging frame.

13 . The transmit/receive point of claim 11 , wherein the programming further includes instructions to transmit at least one paging transmission time interval (TTI) in each of the beams, wherein the bitmap is transmitted in each paging TTI.

14 . The transmit/receive point of claim 13 , wherein a number of paging TTIs transmitted is part of a paging configuration.

15 . The transmit/receive point of claim 11 , wherein the programming further includes instructions to hash the identity of the UE to determine a paging TTI within a plurality of paging TTIs in which the bitmap is to be transmitted.

16 . A user equipment (UE) comprising:
a processor; and a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
hash an identity of the UE to determine a paging frame in which a page is to be sent to the UE and to determine a position of an indicator in a bitmap to be sent to the UE, wherein a value of the indicator indicates whether a page message associated with a paging group to which the UE belongs is transmitted in a current paging cycle;
identify a preferred downlink beamformed beam from a plurality of downlink beams within the paging frame in which the UE is capable of receiving a downlink transmission;
monitor the preferred downlink beam during the paging frame to receive the bitmap; and
when the value of the indicator indicates that the page message is transmitted in the current paging cycle, receive and decode the page message to determine whether the UE is being paged.

17 . The UE of claim 16 , wherein a number of entries in the bitmap is equal to a number of paging groups in the paging frame.

18 . The UE of claim 16 , wherein a number of paging transmission time intervals (TTIs) the UE is specified to receive is variable.

19 . The UE of claim 16 , wherein the programming further includes instructions for the UE to listen to enough paging TTIs to receive the bitmap with at least a threshold reliability.

20 . The UE of claim 16 , wherein the programming further includes instructions to hash the identity of the UE to determine a paging TI within a plurality of paging TTIs in which the bitmap is to be received.
