Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, and a terminal for determining a paging start position.
Background
In an LTE (long term evolution) system, a Paging (Paging) message may transmit a call request to a terminal in an rrc_idle (RRC IDLE state) state. Paging supports discontinuous reception (Discontinuous Reception, DRX), so that a terminal in rrc_idle state "wakes up" only on a specific subframe (called PO, paging timing) of a specific Frame (called PF, paging Frame) within its Paging cycle, to listen to a PDCCH (Physical Downlink Control Channel ) scrambled with a P-RNTI (Paging-RNTI Radio Network Tempory Identity, paging radio network temporary identity), and can maintain a "sleep" state at other times, which can reduce power consumption and improve battery usage time of the terminal.
The PO is a subframe on which there may be a PDCCH scrambled using the P-RNTI and indicating a paging message. When DRX is used, the terminal only needs to detect 1 PO per DRX cycle, that is, only one subframe is available for transmitting pages per paging cycle for each terminal. DRX cycle and paging cycle are the same concept.
The PF is a radio frame that may contain one or more POs. For a certain terminal, the PF is a system frame for sending paging, and the PO is a subframe for sending paging in the PF.
The calculation of paging position in 5G NR (New Raido) introduces two modes, one (default association ) paging DCI (Downlink Control Information, downlink control information) position default is the same as the RMSI (Remaining minimum system information, residual minimum system information) search space position; another (non-default association ) is to configure a search space through the network to let the terminal find the location of paging DCI.
For non-default association, the PF and PO calculation formula is the same as LTE, but PF may indicate the start position of the frame containing the PO, i_s indicates that the terminal needs to detect the i_s+1th PO, and includes n_ssb (the number of synchronization signal blocks SSB) of continuous PMOs (Paging monitoring occasion, paging monitoring opportunity). The paging search space is configured as follows:
monitoring period of PDCCH;
monitoring offset of the PDCCH (0 to Monitoring-periodicity-PDCCH-slot-1);
Monitoring-symbols-PDCCH-witin-slot (1 bitmap of size 14,one bit corresponding to a OFDM symbol): a monitoring symbol of the PDCCH in the time slot, a bit map with the size of 14, wherein one bit corresponds to one OFDM symbol;
CORESET-time-duration Number of consecutive OFDM symbols in a PDCCH monitoring occasion: the duration of the resource set (the consecutive number of OFDM symbols in the PMO) is controlled.
In the paging search space configuration, for a paging search space containing Ns POs, the number of SSBs is N SSB For a PF, the absolute length L of a PF is
A time slot in which N PMO The number of PMOs in a slot is indicated and is determined by Monitoring-symbols-PDCCH-witin-slots.
In the existing scheme, when N (the number of PFs included in one DRX cycle) and Ns (the number of POs included in each PF) are improperly configured, the following two problems may result:
1. from the page search space configuration, it may be detected that the location of the PMO is not utilized.
For example, for a terminal, wake up once every T frames, have a PF in every two frames in every DRX cycle, have 2 POs in every PF, have T POs in the whole DRX cycle, and the UE finds out the frame and PO location that satisfies itself according to the calculation. For example, according to the configuration of the paging search space, 2 PMOs may be configured in one slot, the monitoring period of the PDCCH is 4 slots, so there are 10 PMOs in 2 frames, since n_ssb=4, each PO is 4 PMOs, ns=2, so 8 PMOs are occupied in two frames in total, and according to the existing mechanism, the remaining two PMOs cannot be configured as POs, resulting in waste.
2. The configured N or NS is not matched, which causes the PO monitored by different terminals to collide with the PO of the next PF, and causes the terminals to fail to receive the paging message.
For example, according to the configuration of the paging search space, 2 PMOs may be configured in one slot, the monitoring period of the PDCCH is 4 slots, so that there are 10 PMOs in 2 frames, since n_ssb=4, each PO is 4 PMOs, ns=4, so that the PO contained in the PF in every two frames needs 16 PMOs, actually occupies 3 frames, so that PO overlap occurs, so that the POs of two terminals adjacent to the SFN (difference 2) of the PF overlap, and a certain terminal may not receive a page.
In the case of problem 2, paging is ineffective, and thus is avoided as much as possible by configuration, but in order to avoid collision, problem 1 will necessarily occur, resulting in waste of resources.
For the problem 1, ideally, every time slot containing PMO is reasonably utilized, no resource is wasted, and to achieve such an effect, the PF calculated by the terminal may not contain the position where one paging starts; or that the PF in the conventional sense no longer exists, the page containing the UE starts with a certain subframe of a certain frame.
