Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent 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 certain aspects of the present application, as detailed in the appended claims. All other embodiments, which can be derived by a person skilled in the art from the detailed description herein without making any creative effort, shall fall within the scope of protection of the present application.

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

In consideration of power saving of the terminal, a DRX (Discontinuous Reception) transmission mechanism is introduced in LTE (Long Term Evolution). When no data is transmitted, the power consumption can be reduced by stopping receiving the PDCCH (at the moment, the PDCCH blind detection is stopped), so that the service time of a terminal battery is prolonged. The basic mechanism of DRX is to configure one DRX cycle (cycle) for being in an RRC _ CONNECTED (Radio Resource Control _ CONNECTED) state. Fig. 3 is a diagram illustrating a discontinuous reception cycle according to an embodiment of the present application. As shown in fig. 3, the DRX cycle is composed of "On Duration" and "Opportunity for DRX (sleep period)": in the "On Duration" time, the terminal monitors 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 the paging message is also a DRX mechanism in an RRC _ IDLE (Radio Resource Control IDLE) state, where the DRX cycle is a period of the paging message. As shown in fig. 2, in the time domain, time is divided into successive DRX cycles.

In 5G (5th generation mobile networks/5th generation wireless systems, fifth generation mobile communication technology) and LTE evolution projects, an enhanced DRX mechanism is currently discussed, for example, although a network configures a DRX mechanism for a terminal, the terminal is scheduled only opportunistically during a periodically occurring on duration, and even when the terminal service load is very low, the terminal is scheduled only in a few DRX cycles; for paging messages using the DRX mechanism, the terminal receives the paging message less frequently. Therefore, after the terminal configures the DRX mechanism, there still exist a plurality of PDCCH detections in the 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 will be wasted. There is therefore a further optimization space for current DRX mechanisms.

One solution at present is that, if a base station determines that a terminal needs to be scheduled on duration of DRX, an energy-saving signal is sent to the terminal before the on duration of DRX, where the energy-saving signal is used to wake up the terminal, so that the terminal performs PDCCH detection on the on duration of DRX; otherwise, if the base station determines that the terminal does not need to be scheduled on duration of DRX, the base station may instruct the terminal not to perform PDCCH detection within the on duration of DRX.

In addition, in the research, it is found that the energy saving signal can be used to wake up the terminal to detect the PDCCH, and can also be used to indicate energy saving indication information such as target BWP (Bandwidth part) used when the terminal wakes up, configuration of PDCCH search space used, and dormancy (sceldownlink) indication information of the secondary cell.

The energy-saving signal may be based on a PDCCH channel, and the PDCCH channel is used to carry energy-saving indication information, so that the energy-saving signal can directly multiplex the existing PDCCH design, including coding, scrambling, resource mapping, search space, CORESET (control resource set), and the like, and thus the standardized workload is small.

Since the conventional system already supports the PDCCH channel, the PDCCH-based energy-saving signal has good multiplexing characteristics compatible with other channels such as a PDSCH (Physical downlink shared channel).

The PDCCH-based energy saving signal includes PDCCH DCI (Downlink control information), in which each ue occupies one or more indicator bits in the PDCCH DCI based on an energy saving technique configured by the network for the ue, and the network may configure which indicator bits are used by each ue.

NR (New radio) specifies that PDCCH DCI can carry 12 bits of minimum load due to performance limitations of coding, and thus PDCCH-based power saving signal PDCCH DCI carries at least 12 bits of information. If the effective information bits that need to be carried in the power saving signal PDCCH DCI are fewer, for example, only the indication information of two ues needs to be carried, and both ues only configure the bit indicating "wake-up", that is, each ue only needs 1 bit, and the two ues need 2 bits in total. For another example, the energy saving signal PDCCH DCI carries indication information of two users, where one user only configures 1 bit for "indicating wake-up", and the other user configures 1 bit for "indicating wake-up" and 2 bits for indicating bit of scell dormant (scell dormant may be 5 bits at most), that is, the PDCCH only needs to carry valid information of 4 bits, in a payload carried by the PDCCH DCI, energy saving indication information bits sent to one or more terminals are valid information bits, and other bits are idle bits. The current format for PDCCH DCI is DCI 3-0. The CRC (Cyclic Redundancy Check) for the PDCCH is performed by PS-RNTI (Power Saving Radio Network Temporary Identifier).

In these scenarios, the payload 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 reception of signals objectively. If the user knows the effective load length information of the energy-saving signal PDCCH DCI, some favorable detection algorithms can be adopted to realize the improvement of the detection performance of the energy-saving PDCCH. The following detailed description of the present application will describe in detail how the user terminal B and/or the user terminal C perform reception detection on a signal transmitted by the base station a, so as to solve the technical problem of resource waste generated during signal reception.

The length information is used for indicating effective information bits carried by the energy-saving signal PDCCH DCI. The PDCCH DCI needs to carry 12 bits of information at least, but the effective information bits may be smaller than or even much 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 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.
