Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present application. Rather, they are merely examples of methods and apparatus consistent with aspects of the present application as detailed in the accompanying claims. All other embodiments, which are obtained by persons skilled in the art without making any inventive effort, are within the scope of the present application based on the embodiments in this application.

Fig. 1 and 2 are system architectures of communication systems to which the following embodiments of the present application may be applied. The system architecture comprises: base station A, user terminal B. And a base station A, a plurality of user terminals B and C, etc.

For terminal power saving, a DRX (Discontinuous Reception ) transmission mechanism is introduced in LTE (Long Term Evolution ). When there is no data transmission, the power consumption can be reduced by stopping receiving the PDCCH (at this time, stopping the PDCCH blind detection), so as to improve the service time of the terminal battery. The basic mechanism of DRX is to configure one DRX cycle for being in rrc_connected (Radio Resource Control _connected) state. Fig. 3 is a schematic diagram of a discontinuous reception cycle according to an embodiment of the present application. As shown in fig. 3, the DRX cycle consists of "On Duration" and "Opportunity for DRX (sleep period)": during the "On Duration" time, the terminal listens for and receives the PDCCH (active period); during the "Opportunity for DRX" time, the terminal does not receive the PDCCH to reduce power consumption (sleep period). In addition, the transmission of paging message is also a DRX mechanism in rrc_idle (Radio Resource Control _idle) state, where the DRX cycle is the period of paging message. As shown in fig. 2, in the time domain, time is divided into successive DRX cycles.

In 5G (5 th generation mobile networks/5th generation wireless systems, fifth generation mobile communication technology) and LTE evolution, enhancement mechanisms of DRX are currently being discussed, for example, although a network configures a DRX mechanism for a terminal, the terminal is only scheduled opportunistically in on duration that occurs periodically, and even if the terminal has a low traffic load, the terminal is scheduled in only a few DRX cycles; for paging messages employing the DRX mechanism, the terminal has fewer occasions to receive the paging message. Therefore, after the terminal configures the DRX mechanism, there are still a plurality of PDCCH detections in on duration, and no data scheduling is detected, and if the terminal blindly detects the PDCCH when there is no data scheduling, the detected power is wasted. There is therefore still further room for optimization for current DRX mechanisms.

The current solution is that if the base station judges that the terminal needs to be scheduled at the on duration of the DRX, an energy-saving signal is sent to the terminal before the on duration of the DRX, and the energy-saving signal is used for waking up the terminal, so that the terminal detects the PDCCH at the on duration of the DRX; otherwise, if the base station determines that the terminal does not need to be scheduled in the on duration of the DRX, the terminal may be instructed not to detect the PDCCH in the on duration of the DRX.

In addition, it is found in the study that the energy saving signal may be used to instruct the terminal to wake up the target BWP (Bandwidth part) and PDCCH search space (search space) configuration used when the terminal wakes up, and the energy saving instruction information such as the sleep (scell dorsum) instruction information of the secondary cell.

The energy-saving signal can be based on the PDCCH, and the existing PDCCH design can be directly multiplexed by adopting the PDCCH to bear energy-saving indication information, including the aspects of coding, scrambling, resource mapping, search space, CORESET (control resource set) and the like, so that the standardized workload is smaller.

Because the existing system already supports the PDCCH channel, the energy-saving signal based on the PDCCH has good compatibility and multiplexing characteristics with other channels, such as PDSCH (Physical downlink shared channel ) and the like.

The PDCCH-channel-based power saving signal includes PDCCH DCI (Downlink control information ) in which each user terminal occupies one or more indication bits in PDCCH DCI based on a power saving technique configured by the network for the terminal, which indication bits the network can use by configuring each user terminal.

NR (New radio) specifies that PDCCH DCI carries at least 12 bits of information based on a power saving signal PDCCH DCI of PDCCH because of performance limitations of coding, and the load that DCI can carry is at least 12 bits. If the effective information bits needed to be carried in the PDCCH DCI of the energy-saving signal are fewer, for example, only the indication information of two user terminals needs to be carried, and the two user terminals are configured with only the bit of "indication wake-up", that is, each user terminal needs only 1 bit, and the total two user terminals need 2 bits. For another example, the energy-saving signal PDCCH DCI carries indication information of two users, wherein one user is configured with 1 bit for "indicating wake-up", the other user is configured with 1 bit for "indicating wake-up" and 2 bits for indication bits of scell dorsum (scell dorsum may be 5 bits at most), that is, the PDCCH only needs to carry 4 bits of effective information, in the payload carried by the PDCCH DCI, the energy-saving indication information bit sent to one or more terminals is the effective information bit, and the other bits are idle bits. The format for PDCCH DCI is currently DCI 3-0. The CRC (Cyclic Redundancy Check ) for the PDCCH is performed by a PS-RNTI (Power Saving Radio Network Temporary Identifier, energy saving radio network temporary identifier).

In these scenarios, the load of the power saving signal PDCCH DCI is at least 12 bits, but the payload is smaller or even much smaller than 12 bits. Therefore, there is a certain waste of bit resources in the signal reception. If the user knows the effective load length information of the energy-saving signal PDCCH DCI, a plurality of beneficial detection algorithms can be adopted, so that the improvement of the detection performance of the energy-saving PDCCH is realized. The following detailed description of the present application will describe in detail how the ue B and/or the ue C perform reception detection on a signal sent by the base station a, so as to solve the technical problem of resource waste generated during signal reception.

Fig. 4 is a flow chart of a method of signal reception according to an embodiment of the present application. As shown in fig. 4, the method of signal reception may include the steps of:

in step 130, length information indicating effective information bits carried by the energy-saving signal and sent by the network device is obtained.

The energy-saving signal may be PDCCH DCI, and the effective information bits are energy-saving indication information bits sent to one or more terminals in a payload carried by the energy-saving signal PDCCH DCI. The length information is used for indicating effective information bits carried by the power saving signal PDCCH DCI. The PDCCH DCI requires a minimum of 12 bits of information, but the effective information bits may be smaller or even far smaller than 12 bits, so that length information indicating the effective information bits in the energy-saving signal PDCCH DCI needs to be acquired, so that the received signal detection is performed according to the effective information corresponding to the length information, and resource waste generated during the received signal detection is reduced. The power saving signal PDCCH DCI may be configured to be a minimum of 12 bits, and may also be configured to be the same length as other DCI.

In step 150, a power saving signal is detected based on the length information.

And detecting the energy-saving signal according to the acquired length information. After the energy-saving analog signal for receiving signal detection is generated through simulation, the energy-saving signal is detected based on a sequence detection mode, the energy-saving analog signal generated through simulation is compared with the energy-saving signal for detection, the energy-saving analog signal identical to the energy-saving signal is detected through comparison, namely the receiving signal detection is completed, and the receiving of the energy-saving signal is completed.

According to the embodiment, the energy-saving signal is detected according to the length information of the effective information bit carried by the energy-saving signal, so that signal receiving is realized by using fewer resources, the signal receiving performance is improved, and the technical problem of resource waste generated during signal receiving is solved.

Fig. 5 is a flow chart of a method of signal reception according to one embodiment of the present application. As shown in fig. 5, the method includes:

in step 110, length information indicating the effective information bits carried by the power saving signal is sent to the terminal device.

The energy-saving signal may be PDCCH DCI, and the length information is used to indicate valid information bits carried by the PDCCH DCI. When the network device configures the energy-saving signal PDCCH DCI to the terminal, the network device configures basic configuration required by the energy-saving technology, for example, the bit number of energy-saving information required by the terminal, the position of energy-saving indication information of the terminal in the PDCCH DCI, the length information of the energy-saving signal PDCCH DCI, and the like. The length information of the effective information bits carried in the PDCCH DCI of the energy-saving signal is also required to be configured. The power saving signal PDCCH DCI may be configured to be a minimum of 12 bits, and may also be configured to be the same length as other DCI. When the effective information bits are larger, that is, the effective information bits carried in the PDCCH DCI of the energy-saving signal are more, the length information indicating the effective information bits carried in the energy-saving signal may not be configured. And transmitting an energy-saving signal according to the length information. And transmitting the energy-saving signal containing the effective information bit according to the length information of the effective information bit carried by the energy-saving signal.

The PDCCH comprises a payload and CRC check bits, and energy-saving indication information bits sent to one or more terminals in the payload carried by the PDCCH DCI are effective information bits, and other bits are idle bits. The other information bits except the effective information bits in the payload carried by the energy-saving signal PDCCH DCI are predefined specific values, and the predefined specific values can be both 0 and 1 or other specific bit sequences. The length information may be carried in a radio resource control (Radio Resource Control, RRC) or a medium access control unit (Medium Access Control Control Element, MAC CE) or a power saving signal, and when the length information is carried in the power saving signal, a specific field may be set in the power saving signal PDCCH DCI for indicating the length information. Bits corresponding to the length information may be located in a front part bit or a rear part bit in a payload carried by the energy-saving signal, so as to obtain the length information of the effective information bits. The bits corresponding to the length information may be located at other positions set in the power saving signal. The length information may also correspond to a bitmap for indicating location information of valid information bits carried by the power saving signal, and the bitmap may be used for indicating which bits in the PDCCH DCI are valid information bits.

The length information may be length information corresponding to a predefined radio network temporary identifier (Radio Network Temporary Identifier, RNTI). The network device may configure the terminal with a plurality of radio network temporary identifiers in advance, each radio network temporary identifier corresponding to length information indicating valid information bits carried by the power saving signal. The radio network temporary identifier may be a PS-RNTI, and the detection is performed based on length information corresponding to the radio network temporary identifier PS-RNTI when detecting the received signal.

Step 150 in the specific implementation corresponding to fig. 4 above includes, in a specific flow of another example: step 151 and step 153.

In step 151, a power saving analog signal is generated based on the length information.

The energy-saving analog signal is an analog signal for detecting a received signal of the energy-saving signal. According to the length information, the effective information bit length M carried by the energy-saving signal PDCCH DCI is obtained, other information bits except for effective information bits in the effective load carried by the PDCCH DCI are predefined specific values, and the predefined specific values can be 0, 1 or other specific bit sequences. According to the effective information bit length M (M < 12), the terminal can assume the possible values of sequences of M effective information bits according to the M-th power probability of 2, and generate M-th power PDCCH signals at the terminal, namely energy-saving analog signals, based on the possible values and a specific value predefined by other information bits except the effective information bits in the payload carried by the energy-saving signal PDCCH DCI, and then detect the energy-saving signal PDCCH DCI based on a sequence detection mode. Because all bits in the energy-saving signal PDCCH DCI are utilized, the complete energy-saving signal is reconstructed, and the relevant detection operation is carried out with the received energy-saving signal, all signal bits in the PDCCH are fully utilized, including other information bits except effective information bits in the effective load carried by the PDCCH DCI, and CRC bits are included, so that the detection performance can be greatly improved.

In step 153, a power saving signal is detected based on the power saving analog signal.

Wherein, according to energy-conserving analog signal, detect energy-conserving signal based on the mode of sequence detection. And comparing and detecting the energy-saving analog signal with the energy-saving signal according to the generated energy-saving analog signal, thereby completing the detection of the received energy-saving signal.

According to the energy-saving analog signal detection method and device, energy-saving analog signals are generated according to the length information and the fact that other information bits except effective information bits in the effective load carried by the energy-saving signals are the predefined specific values, and therefore energy-saving signal detection is conducted according to the energy-saving analog signals.
