Embodiment 1
[0186] 1. DCI scrambled by an RNTI other than the P-RNTI.
[0187] The DCI of the CRC scrambled by a non-P-RNTI RNTI (for example, PS-RNTI (power saving RNTI, power saving RNTI)) carries the first information field of L bits, and uses a bitmap to indicate the terminal that needs to detect the PO associated with the DCI Paging detection parameters.
[0188] For example, paging detection parameter = floor(UE_ID / N*Ns) mod L, where N is the number of PFs included in one DRX cycle of the UE, Ns is the number of POs included in one PF, and UE_ID is equal to 5G-S-TMSI mod 1024.
[0189] The POs that can be associated with the DCI are time-division multiplexed. The terminal first detects the DCI, and judges whether it needs to detect the subsequent POs associated with the DCI according to the first information field.
[0190] For example L=6, the 6bits in the DCI correspond to the value (0,1,2,3,4,5) of the paging detection parameter from the high bit to the low bit, if the bit valu...

[0202] The DCI of the CRC scrambled by the P-RNTI carries the first information field of L bits, and the bitmap is used to indicate the paging detection parameters of the terminal that needs to receive the paging message.
[0203] For example, the paging detection parameter = floor(UE_ID / N*Ns) mod L, where N is the number of PFs included in one DRX cycle of the UE, Ns is the number of POs included in one PF, and UE_ID is equal to 5G-S-TMSI mod 1024.
[0204] For example L=6, the 6bits in the DCI correspond to the paging detection parameters (0, 1, 2, 3, 4, 5) from the high bit to the low bit, if the bit value of a certain position is 1, then the corresponding has The terminal with the value of the paging detection parameter needs to detect the paging message in the PDSCH scheduled by the DCI.
[0205] For example, if the 6 bits in the DCI are 010000, the terminal whose paging detection parameter is 1 needs to detect the paging message scheduled by the DCI, and the terminal wh...

Abstract
The invention discloses a paging detection and indication method, equipment and a medium. The paging detection and indication method comprises the following steps of determining a terminal which needs to detect a paging opportunity or receives a paging message; sending the downlink control information carrying a first information domain to the terminal, and indicating the terminal to detect a paging opportunity associated with the downlink control information or receive a paging message scheduled by the downlink control information according to a corresponding relation between a value of the first information domain and a paging detection parameter of the terminal; receiving the downlink control information carrying the first information domain; and determining whether to detect a paging opportunity associated with the downlink control information or receive a paging message scheduled by the downlink control information according to the value of the first information domain corresponding to the paging detection parameter. The method is advantaged in that unnecessary detection paging of the terminal can be avoided, and a large amount of invalid energy consumption can be reduced.
Description
technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a paging detection and indication method, device and medium. Background technique [0002] In 5G NR (New Radio, New Radio), the terminal uses DRX (Discontinuous Reception, Discontinuous Reception) to detect paging messages. The terminal detects a PO (Paging occasion) in each DRX cycle, and a PO is a group of PDCCH (physical downlink control channel, physical downlink control channel) detection opportunities, which may include multiple time slots. The transmission on the PO will be scrambled with P-RNTI (Paging-Radio Network Temporary Identity), indicating the PDCCH of the paging message. PF (Paging Frame, Paging Frame) is a radio frame, which may contain one or more POs. [0003] The disadvantage of the prior art is that according to the current paging design, UE (User Equipment, User Equipment) will generate invalid detection. Contents of the invention...
