In a broader sense, as long as there is channel tracking All functional CSI-RSs can be used as energy-saving signals in the embodiments of the present disclosure.
- the terminal receives the paging indication formed by the first TRS and/or the second TRS, and determines whether it needs to receive a paging signal in one or a group of subsequent POs according to a preset rule.
- Its beneficial effect mainly lies in that there is no LTE-Common Reference Signal (CRS) in RRC Idle/Inactive mode, if acquiring accurate synchronization information with a low signal-to-noise ratio generally requires 3 synchronization signal block (synchronization signal block, SSB) cycles That is, 60ms, which will cause a large loss of power consumption of the terminal, especially in a scenario where there is no paging reception actually.
- CRS LTE-Common Reference Signal
- the use of TRS/CSI-RS-based paging indication signals on the one hand does not require strict synchronization, which reduces the power consumption of receiving paging indications. information. More specific features are as follows: the first TRS is a cell-specific TRS, and the second TRS is specific to a terminal group, and a special case that a group of UEs only includes one UE is not excluded.
- the preferred first TRS/CSI-RS can be scrambled with Cell ID, and the preferred second TRS/CSI-RS is scrambled with Cell ID and UE group ID, in order to distinguish terminals and avoid inter-cell interference.
- the terminal group ID is preferably determined by the base station broadcast configuration and/or standard predetermined rules.
- the preferred base station can use system information (SI, System Information) to notify the terminal group number M in a broadcast manner.
- SI System Information
- the terminal is based on UEID and UEID.
- the above-mentioned scrambling process generally means that the initial value of the TRS/CSI-RS sequence is a function of the scrambling ID, or a multiplication or addition operation is performed on the target sequence and a function of the scrambling ID. All terminals in the cell in Idle/Inactive mode and associated with the PO can detect the first TRS/CSI-RS and/or the second TRS/CSI-RS on the resources corresponding to the PO.
- the first and second TRS/CSI-RS correspond to different transmission resources, so that the false detection probability of the first and second TRS/CSI-RS can be reduced.
- the base station notifies the number of time slots occupied by the first and/or second TRS/CSI-RS through broadcast signaling or a standard pre-agreed manner, and the number of time slots may be 1 or 2 or other values.
- the same notification method is adopted for the number of time slots occupied by the TRS/CSI-RS used for or assisting the paging indication described in the subsequent embodiments, which will not be repeated in the following.
- the base station side only sends the first TRS/CSI-RS on the first TRS/CSI-RS resource or sends the second TRS/CSI-RS on the second TRS/CSI-RS resource each time.
- the first TRS resource and the second TRS resource are within the same first target time period, for example, the first TRS resource and the second TRS resource are within one or several same time slots at the same time, and the first target time period , preferably notified by high-level signaling or a standard pre-agreed manner as described above.
- the beneficial effect of configuring two TRS resources at the base station is that in addition to receiving normal paging information, the terminal also receives paging messages when system information is updated or the base station sends short messages such as earthquake and tsunami warning information.
- the base station uses the PEI sent on the cell-specific first TRS/CSI-RS resource to wake up all terminals that receive such messages, which avoids similarities to the second
- the code division multiplexing adopted for the second TRS sent by the TRS/CSI-RS resource can effectively improve the performance of the paging indication corresponding to this type of message.
- the two TRS/CSI-RS transmission resources are configured in the same first target time period, which brings the beneficial effect that since there are two transmission TRS/CSI-RS resources, the terminal may need to perform two times on the two resources.
- the base station configures the two TRS resources in the same first target time period, such as in the same slot, which is beneficial for the terminal to detect the TRS/CSI-RS signals of the two resources with lower power consumption.
- Terminal behavior can depend on the terminal implementation:
- Terminal behavior It depends on the implementation of the terminal.
- one way of the terminal may be: a better terminal first detects the resources corresponding to the first TRS/CSI-RS, and only if the first TRS/CSI-RS cannot be detected. The resource corresponding to the second TRS/CSI-RS is detected. If the terminal detects the first TRS/CSI-RS on the first resource, the terminal does not continue to detect the resource corresponding to the second TRS/CSI-RS, and wakes up the receiver to receive subsequent paging messages; if the terminal detects the second TRS /CSI-RS, the terminal only wakes up the receiver according to the second TRS/CSI-RS instruction to receive the corresponding paging message.
- the performance gain brought by this solution is that the first TRS/CSI-RS can be received by all corresponding terminals because it is a cell-level reference signal, and the sequence does not use the code division method, so that the first TRS/CSI-RS has excellent performance
- the base station if the base station notifies the terminal of a system message change or receives a short message, all terminals need to receive the paging message.
- the base station only needs to send the first TRS to wake up all the terminals, thereby saving the overhead on the base station side.
- the second TR/CSI-RS uses UE group ID for scrambling to distinguish users corresponding to POs. Only some terminals that detect the second TRS/CSI-RS will wake up the receiver and continue to detect subsequent paging signals.
- the terminal that detects the second TRS/CSI-RS will continue to sleep, so the second TRS/CSI-RS helps the terminal to further save energy. Since the first TRS/CSI-RS is not sent when the second TRS/CSI-RS is sent, it does not happen that the terminal receives two TRS/CSI-RS at the same time, and the terminal detects the first TRS/CSI-RS first, and then detects The second TRS/CSI-RS is not detected until after the first TRS/CSI-RS, so it will not cause confusion of the terminal's understanding of the base station indication. Of course, this solution does not exclude that the terminal first detects the resources corresponding to the second TRS/CSI-RS and then detects the resources corresponding to the first TRS/CSI-RS. The resources are similar.
- the terminal If the terminal detects the resources corresponding to the second TRS/CSI-RS on the resources corresponding to the second TRS/CSI-RS, it will no longer detect the paging indication corresponding to the resources corresponding to the first TRS/CSI-RS.
- the probability of sending a paging indication is lower than that of a UE group, so it may be more energy efficient to first detect the corresponding group common TRS/CSI-RS paging indication of the second resource.
- the beneficial effect of this method is that, in addition to not causing the terminal confusion, the base station side saves overhead, the terminal does not have to detect the paging indications of two resources, and the detection power consumption can be saved.
- another method of the terminal may be: the terminal detects TRS/CSI-RS on the first and second TRS/CSI-RS respectively, if the terminal detects only the first or second TRS/CSI-RS RS, the terminal receives the paging message according to the TRS/CSI-RS based paging indication; when the terminal simultaneously detects the first TRS/CSI-RS and the resources corresponding to the second TRS/CSI-RS for the paging indication For one TRS/CSI-RS and the second TRS/CSI-RS, the terminal wakes up the receiver to receive the corresponding paging message.
- sequence-based paging indication signal does not have a CRC check like the PDCCH, there is a certain probability of false detection, so both TRS/CSI-RS resources may detect the paging indication. Directly waking up the receiver to receive paging is beneficial to reduce the paging reception delay.
- Scheme 2 The base station side sends the first TRS/CSI-RS on the first resource and/or sends the second TRS/CSI-RS on the second resource.
- the terminal detects the first and second TRS signals on resources corresponding to the first and second TRS/CSI-RS.
- the first TRS can be scrambled with either of two preset sequences in addition to the Cell ID scramble.
- the first preset sequence is, for example, an all-zero sequence [0 0 0 0... Let the sequence eg alternate sequence [1,0,1,0,1,0,...1,0,...].
- the terminal If the terminal detects the first TRS/CSI-RS scrambled by the first preset sequence and its Cell ID, it wakes up the receiver to receive subsequent paging messages, preferably the terminal does not detect the second TRS/CSI-RS If the terminal detects the first TRS/CSI-RS scrambled by the second preset sequence and its Cell ID, the terminal continues to detect the second TRS/CSI-RS scrambled by the Cell ID and its UE group ID on the second resource , if the terminal detects the second TRS/CSI-RS on the second resource, it wakes up the receiver to receive subsequent paging messages, and if the terminal does not detect the second TRS/CSI-RS, it continues to sleep; One TRS/CSI-RS, the terminal will not detect the second TRS/CSI-RS.
- Scheme 2 has similar advantages to scheme 1, but compared with scheme 1, it results in higher system overhead because both the first and second TRS/CSI-RS may be transmitted, but since the second TRS/CSI-RS must detect the first Only one TRS/CSI-RS can be detected, so the false alarm probability of the second TRS/CSI-RS can be reduced, and when no terminal is paged in the current PO, only the first TRS/CSI-RS needs to be detected, Power consumption savings may occur.
- the performance of sequence-based paging indication will be poor without channel estimation.
- the first TRS/CSI-RS is scrambled with different scrambling code sequences, regardless of whether it is sent or not.
- the paging message always transmits the first TRS/CSI-RS deterministically.
- the terminal can perform channel estimation and time/frequency offset estimation in advance to assist the second TRS/CSI-RS. Reception of CSI-RS, and reception of subsequent paging messages.
- the base station is a terminal in RRC Idle/Inactive mode, before one or a group of POs, sends an energy-saving signal for PEI, the PEI corresponds to one or a group of POs, and the PEI includes the first TRS or the first TRS/CSI-RS and the The second TRS/CSI-RS, the base station sends the first TRS/CSI-RS on the first resource, and sends the second TRS/CSI-RS on the second resource, the first TRS/CSI-RS and the second TRS/CSI -RS are all used for paging indication.
- the first TRS/CSI-RS is a UE group-specific signal
- the second TRS/CSI-RS is also a UE group-specific signal, which does not exclude the special case that only one terminal is included in a group of terminals.
- the preferred first or second TRS/CSI-RS can at least be scrambled by the Cell ID and the terminal group ID, and the method is as described in Embodiment 1; in addition, the paging indication scrambling information based on TRS/CSI-RS also includes
- the paging time information may include preferably the starting OFDM symbol information of the PO, and/or the paging indication information corresponds to the starting time information of the MO, such as the starting time slot of the MO and/or the starting OFDM symbol of the MO information. Its beneficial effects are mainly reflected in: since the base station can use multiple beams to send paging information whether it is FR1 or FR2, the MO in each paging opportunity (PO) in each paging (PF) frame will correspond to different beam directions.
- PO paging opportunity
- PF paging
- Different MOs also correspond to the paging indication information of different beams, and the starting position of the MO depends on the first PDCCH MO of the PO configured by the high-level signaling, and the first PDCCH MO notified by the high-level signaling
- the starting OFDM symbol of an MO so preferably the paging information indication should include the starting OFDM symbol information of the PO, and/or the starting time slot of the MO and/or the starting OFDM symbol information of the MO.
- the TRS resources corresponding to the multi-beam MO may collide, and the time information of the PO and the MO can effectively eliminate the interference between the paging indications caused by the overlap between the paging indications.
- the base station only sends the first TRS/CSI-RS scrambled by the Cell ID and the terminal group ID and its paging PO and/or MO time information for paging indication, preferably broadcast signaling Or the standard notifies in advance the maximum number of UE groups supported by a sending resource, and the base station sends paging indication information to wake up different terminal groups on the same resource.
- the terminal performs joint detection on all OFDM symbols in the first TRS. For example, assuming that one TRS/CSI-RS occupies one time slot and contains symbols 4 and 8, the terminal concatenates the TRS/CSI-RS signals of symbols 4 and 8 in series.
- Joint detection is performed together; assuming that one TRS/CSI-RS contains two time slots, the TRS in each time slot is located in symbols 4 and 8, then the terminal concatenates the TRS/CSI-RS of 4 symbols serially for detection, using TRS
- the beneficial effect of /CSI-RS symbol concatenation for joint detection is that the TRS detection performance can be significantly improved.
- the base station sends the first TRS/CSI-RS and the second TRS/CSI-RS scrambled by the Cell ID and the terminal group ID and its paging PO and/or MO time information for paging indication , the optional first TRS/CSI-RS and the second TRS/CSI-RS scrambling code information may also include the sequence number information of the TRS/CSI-RS itself, for example, the TRS/CSI-RS index is 0 or 1 respectively for Distinguish the first TRS and the second TRS as part of the scrambling information.
- the first TRS/CSI-RS and the second TRS/CSI-RS have the same Cell ID and its UE group ID identification
- the base station side uses the first TRS/CSI-RS and the second TRS/CSI-RS -
- the RS collectively indicates paging reception for a group of UEs.
- the terminal serially concatenates all symbols of the first TRS/CSI-RS and the second TRS/CSI-RS in time sequence, and performs joint detection to increase the length of the detection sequence, for example, the first TRS /CSI-RS contains 4 OFDM symbols, and the second TRS contains 6 OFDM symbols.
- the terminal can serially concatenate the TRS of 10 OFDM symbols in the agreed order for joint detection to obtain better detection performance and reduce probability of missed detection.
- the base station sends an energy-saving signal corresponding to a PEI or a group of POs, and the PEI includes the first TRS/CSI-RS and /or second TRS/CSI-RS.
- the first/CSI-RS and the second TRS/CSI-RS may occupy the same or different number of time slots, but the length of the time domain is an integer multiple of the number of time slots.
- the base station when the base station adopts multi-beam transmission, since the base station does not know the location of the terminal, the base station needs to send paging messages on each beam.
- the TRS-based paging indication adopts the time domain transmission structure shown in FIG. 8 .
- the simple paging indication time domain transmission structure will occupy 16 time slots, ie, 8 ms.
- the present embodiment can improve the transmission finger transmission mode that further reduces power consumption, and the details are as follows:
- One paging indication consists of at least one pair of TRS/CSI-RS.
- the patterns/resources of at least one pair of TRS/CSI-RS constituting the paging indication are configured within the target time unit, and the patterns/resources of multiple pairs of TRS/CSI-RS within the target time unit have the same transmit beam, that is, the target time unit
- the patterns/resources of multiple pairs of TRS/CSI-RS in the TCI have the same TCI state, and the target time unit preferably refers to one time slot for NR, or two time slots, which is not excluded for other systems. Other time units such as subframes.
- different target time units are transmitted using different beams. A specific example is shown in FIG.
- the paging indication is composed of the first and second TRS/CSI-RS.
- the first TRS/CSI-RS and the second TRS/CSI-RS are configured in the target time unit, that is, within a time slot. In time slot 1, beam 1 is used for transmission, in time slot 2, beam 2 is used for transmission, and in time slot 2 N is transmitted using beam N.
- the beneficial effect is that compared with the method shown in FIG. 8 , the sending time of the paging indication can be greatly shortened, which is beneficial to power saving, and at the same time, the same beam is used on the target unit to send the base station side, and the implementation is simple.
- One paging indication consists of at least one pair of TRS/CSI-RS.
- the pattern/resource of at least one pair of TRS/CSI-RS constituting the paging indication is configured within the target time unit, at least one paging indication is configured within the target unit time, and the pattern/resource of the corresponding at least one pair of TRS/CSI-RS is At least one transmission beam is sent, that is, each paging indication has the same transmission beam, and different paging indications are sent using at least one transmission beam. Further, preferably, the paging indications or TRS/CSI-RS resources in different target time units are sent using different beams.
- a specific example may be, assuming that the paging indication only includes the first TRS/CSI-RS and the first TRS/CSI-RS occupies only one time slot, the base station may also configure multiple paging indications corresponding to the first time slot. Multiple TRS/CSI-RS patterns/resources, as shown in Figure 4 above, the TRS resources that constitute a paging indication are sent using different beams, that is, beam 1 and beam 2. In the second time slot, the base station is in the beam 3 and beam 4 repeatedly send paging indications. In the third time slot, the base station repeatedly sends paging indications on beams 5 and 6, and in the fourth time slot, the base station repeatedly sends paging indications on beams 7 and 8.
- the paging indication is composed of the first TRS/CSI-RS and the second TRS/CSI-RS.
- a paging indication transmission is configured within a target unit time (eg, a time slot), and corresponding two pairs of TRS/CSI-RS patterns/resources are configured within a target unit time (eg, a time slot) corresponding to a paging indication scenario.
- the first TRS/CSI-RS and the second TRS/CSI-RS that constitute different paging indications in each time slot are sent using the same beam, and the first TRS/CSI-RS and the second TRS/CSI that correspond to different paging indications -RS pairs are sent using different beams.
- the second TRS and the first TRS/CSI-RS may be configured on the same symbol as shown in FIG. 5 , and of course they may also be configured on different symbols.
- the beneficial effect of this solution is that compared to the same target unit time using only the same beam, significantly fewer time slots can be used to transmit the paging indication, so that the paging indication can obtain a greater energy saving gain. (Cyclic Prefix, CP) can be completed, so it is not technically difficult for the base station to complete multiple beam transmissions in the same time slot.
- the resource configuration of the TRS corresponding to the above paging indication requires the base station to notify the terminal through broadcast signaling such as a system message.
- the base station is in the RRC Idle/Inactive mode terminal on the predetermined resource before one or a group of POs, and sends an energy-saving signal for PEI
- the PEI corresponds to one or a group of POs
- the PEI includes the first TRS/CSI-RS and
- the functions and configuration of the first and second TRS/CSI-RS may be different.
- the second TRS/CSI-RS is a terminal group-specific reference signal.
- the first TRS/CSI-RS is a cell-specific reference signal that is not explicitly scrambled by Cell ID, or a terminal-specific reference signal.
- the TRS/CSI-RS is a reference signal configured by the base station for the terminal in the connected state
- the scrambling ID of the TRS/CSI-RS is the UE-specific configuration for the terminal in the connected state by the base station, and the terminal in the idle mode is notified through high-level signaling.
- the first TRS/CSI-RS it can be divided into the following two implementation solutions.
- the first TRS/CSI-RS is used for synchronization function and not used for paging indication.
- the second TRS supports paging indication, as follows:
- the base station uses high-level signaling to configure the first TRS/CSI-RS and the second TRS/CSI-RS on the corresponding resources for the idle mode terminal.
- the second TRS is scrambled by at least the Cell ID and the terminal group ID, and optionally, the time information of PO/MO can also be scrambled.
- the terminal behavior is that the terminal receives the first TRS/CSI-RS according to the instruction of the base station, the terminal does not perform blind detection on the first TRS/CSI-RS, and the terminal uses the first TRS/CSI-RS to perform a channel tracking operation;
- the second TRS/CSI-RS signal is detected on the upper side, and if the terminal detects the second TRS/CSI-RS or the wake-up indication of the second TRS/CSI-RS, the terminal wakes up the receiver to receive the subsequent corresponding paging message.
- the beneficial effect is that the first TRS/CSI-RS with low detection complexity is always used for synchronization operations, and the first TRS/CSI-RS can be used to assist the second TRS in detecting paging indications.
- the base station uses high-level signaling to configure the first TRS and the second TRS on the corresponding resources for the idle mode terminal.
- Terminal behavior The terminal first detects the first TRS/CSI-RS sequence scrambled by the default scrambling sequence, and if the first TRS/CSI-RS sequence scrambled by the default scrambling sequence cannot be detected, the terminal continues to detect the second scrambling sequence Sequence scrambled first TRS. If the terminal detects the first TRS/CSI-RS sequence, the terminal continues to detect the second TRS/CSI-RS sequence, and determines whether to wake up the receiver to receive according to whether the second sequence or the indication of the second TRS/CSI-RS sequence is detected. paging message. If the terminal detects the TRS/CSI-RS scrambled by the second scrambling sequence, the terminal stops detecting the second TRS/CSI-RS and performs a sleep operation.
- the terminal continues to detect the second TRS/CSI-RS sequence and determines whether the corresponding TRS/CSI-RS in the subsequent Receive paging information in PO. Its beneficial effect is: the TRS/CSI-RS sequence sent for the connected state terminal may actually have no TRS/CSI-RS transmission due to the completion of the data transmission of the connected state terminal, but the base station has notified the terminal of the position of the TRS/CSI-RS.
- the terminal before deactivating the TRS/CSI-RS transmission resource, the terminal always needs to detect, so the terminal first detects the first TRS/CSI-RS scrambled by the default first sequence, because its high probability exists, and The first sequence of scrambling does not affect the connection state terminal receiving TRS/CSI-RS.
- the base station can The first TRS/CSI-RS scrambled by the second sequence is transmitted, and the terminal detects the first TRS/CSI-RS scrambled by the second sequence and notifies the detection of the second TRS/CSI-RS to directly perform a sleep operation.
- the base station sends an energy-saving signal for a paging early stop indication on a predetermined resource before one or a group of POs for a terminal in RRC Idle/Inactive mode, and the paging early stop indication corresponds to one or a group of POs.
- the indication signal is composed of two-level energy-saving signals: the first energy-saving signal is a TRS/CSI-RS signal, and the second energy-saving signal is a PDCCH. Specifically, it can be as follows:
- the first energy-saving signal is a Cell-specific TRS/CSI-RS signal, which is at least scrambled by the Cell ID
- the second energy-saving signal is the group common PDCCH, which is scrambled by a dedicated RNTI, such as PS-RNTI or PEI-RNTI.
- the sequence a0 is the default scrambling sequence, which scrambles the first energy-saving signal, namely the TRS.
- the base station uses the second scrambling sequence for scrambling, otherwise, the first scrambling sequence is used for scrambling; terminal behavior: the terminal first detects the first scrambled by the default scrambling sequence. The energy-saving signal. If the first energy-saving signal scrambled by the default scrambling sequence cannot be detected, the terminal continues to detect the first energy-saving signal scrambled by the second scrambling sequence. If the terminal detects the first power saving signal, the terminal continues to detect the second power saving signal, and determines whether to wake up the receiver to receive paging in the corresponding PO according to whether the second power saving signal is detected or according to the indication signaling of the second power saving signal information.
- the terminal If the terminal detects the TRS/CSI-RS scrambled by the second scrambling sequence, the terminal stops detecting the second power saving signal and performs a sleep operation. If the terminal only detects the second power-saving signal, the terminal determines whether to wake up the receiver to receive the paging signal in the corresponding PO according to the indication of the second power-saving signal.
- the terminal in RRC Idle/Inactive mode needs multiple SSBs to achieve synchronization accuracy because there is no CRS, so the first energy-saving signal is the TRS/CSI-RS signal, which is helpful for the terminal to detect
- the first energy-saving signal or first perform channel estimation hypothesis test on the first energy-saving signal, and then assist in detecting the first energy-saving signal
- use the first energy-saving signal to perform channel estimation and synchronization operations, which facilitates detection of the PDCCH-based energy-saving signal.
- the first energy-saving signal can explicitly instruct the terminal to sleep and not receive paging by using different scrambling modes.
- the base station configures the TRS of the connected terminal for the idle mode terminal, the base station may not send the first energy-saving signal, but only use the second energy-saving signal to wake up the terminal to perform paging reception, thereby reducing system overhead.
- the first energy-saving signal sent on the first resource is a TRS/CSI-RS signal. Since different scrambling sequences can be used to distinguish whether there is a subsequent second energy-saving signal or whether there is paging reception, this A power saving signal is preferably always sent by the base station side regardless of whether there is subsequent paging information.
- the base station side when the base station side indicates that there is a TRS/CSI-RS signal from the terminal in the connected state before the PO (for example, within the preset range before the PO) for the terminal (that is, the base station is the terminal in the connected state)
- the base station deactivates the first energy-saving signal resource, that is, the first energy-saving signal is no longer sent, and the base station only sends the second energy-saving signal;
- the TRS/CSI-RS signal is used, the first and second transmission resources corresponding to the first energy-saving signal and the second energy-saving signal are simultaneously activated, and the base station may transmit the energy-saving signal on the above two resources.
- the above-mentioned transmission of the energy-saving signal can actually be performed by the base station through the implementation method, that is, the base station side is not obliged to send the first energy-saving signal. If there is a TRS/CSI-RS signal of the connected terminal, the base station can The first TRS/CSI-RS signal is not sent or sent on an energy-saving signal sending resource.
