The following clearly and comprehensively describes the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present disclosure. Other embodiments obtained based on the embodiments of the present disclosure.

Where the method and the apparatus are based on the same application concept, and principles of solving problems thereof are similar, for the embodiments of the apparatus and the method, reference can be made to each other, and for the same parts, it will not be described here again.
The embodiments of the present disclosure may be applicable to various systems and, in particular, to a 5G system. For example, an applicable system may be a global system of mobile communication (GSM), a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. The various systems all include a terminal device and a network device, and further include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

In different systems, a name of a terminal device may be different. For example, in a 5G system, a terminal device can be called a user equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal device can be a mobile terminal device, such as a mobile phone (or a “cellular” phone) and a computer with a mobile terminal device, such as a portable, pocket-sized, hand-held, computer-built or vehicle-mounted mobile device, which exchanges languages and/or data with the radio access network, for example, a personal communication service (PCS) phone, a cordless phone, a session initiated protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. The wireless terminal device can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent or a user device, which is not limited in the embodiments of the present disclosure.

Multi Input Multi Output (MIMO) transmission can be performed between the base station and the terminal device by using one or more antennas, respectively, and the MIMO transmission can be single user MIMO (SU-MIMO) or multiple user MIMO (MU-MIMO). According to the shape and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, and it can also be diversity transmission, precoding transmission or beamforming transmission.
The following introduces the random access procedure.
When UE is in an idle state or an inactive state, it needs to initiate random access to a network device (such as a base station, gNB), to obtain communication services provided by the network device. The existing 5G NR supports two random access modes. One is 4-step random access, referred to as 4-step RACH, also known as Type 1 random access; and the other is 2-step random access, referred to as 2-step RACH, also known as Type 2 random access. The 2-step RACH will be explained with reference to
S101: a base station broadcasts and transmits configuration information of a 2-step RACH.
The configuration information of the 2-step RACH indicates a set of random access channel occasion (RACH Occasion, RO) resources and a set of physical uplink shared channel (PUSCH) occasion (PUSCH Occasion, PO) resources. In addition, the 2-step RACH configuration information also indicates a mapping relationship between a synchronization signal block (SSB) and a RO, and a mapping relationship between the RO and a PO.
S102: a UE transmits a message (MsgA) to a base station according to the 2-step RACH configuration information transmitted by the base station and the selected SSB.
Where the UE transmitting the MsgA includes transmitting a pilot sequence (preamble) in the RO corresponding to the selected SSB (if there are multiple ROs, one of them is randomly selected) and transmitting the PUSCH of MsgA in the PO corresponding to the RO.
S103: the base station transmits a message B (MsgB) to the UE according to a receiving result of MsgA.
In addition, for a UE that supports both 4-step RACH and 2-step RACH, it may initiate both 2-step RACH random access and 4-step RACH random access. The process of 4-step RACH is different from that of 2-step RACH, and the base station needs to determine the subsequent process and the signals to be transmitted/received according to the random access mode initiated by the UE.
At present, NR supports two mechanisms to distinguish between 4-step RACH and 2-step RACH:
In addition to distinguishing whether the UE initiates 4-step RACH or 2-step RACH, at present, in the 5G NR system, with the technical evolution, a reduced capability UE (RedCap UE) is proposed. Compared with the ordinary UE (non-RedCap UE), the RedCap UE aims to reduce the complexity and cost of terminal implementation, so the maximum bandwidth supported by the RedCap UE will be smaller than that supported by the ordinary UE. For example, when the carrier frequency is below 6 GHz, the maximum bandwidth of the ordinary UE can be 100 MHz, while the maximum bandwidth of the RedCap UE is only 20 MHz. The minimum number of receiving antennas for the ordinary UE is 4 or 2, while the minimum number of receiving antennas for the RedCap UE is 2 or 1.
No matter which type of UE, it is necessary to initiate random access to the network device to obtain communication services provided by the network device. For example, as shown in
Due to the different reception capabilities of the ordinary UE and the RedCap UE, the earlier the base station knows/identifies whether the UE initiating random access is the ordinary UE or the RedCap UE, the earlier it can make targeted scheduling, thus improving the resource utilization rate of the network. For example, taking 2-step RACH as an example, if the base station recognizes that the UE that initiates random access currently is the RedCap UE, it can use a lower channel coding rate when scheduling MsgB, thus improving the transmission reliability and making up for the loss of reception capacity of the RedCap UE. However, at present, there is no method to distinguish the RedCap UE from the ordinary UE in the 2-step RACH process.
In order to distinguish between the RedCap UE and the ordinary UE in the process of 2-step RACH, we can consider adopting a similar way to that distinguishes whether the UE initiates 4-step RACH or 2-step RACH, for example, the ordinary UE and the RedCap UE use different ROs, or the ordinary UE and the RedCap UE use different preambles. However, this way will cause the RO resource set or preamble set to be divided into smaller sets. For example, taking the distinguishing of RO as an example, a total RO resource set needs to be divided into four small RO resource sets ({ordinary UE, 4-step RACH}, {RedCap UE, 4-step RACH}, {ordinary UE, 2-step RACH} and {RedCap UE, 2-step RACH}). This segmentation of RO resource sets or preamble sets will cause the capacity of random access to decrease.
Therefore, the embodiments of the present disclosure propose that the base station can identify whether the UE is ordinary UE or RedCap UE through the physical uplink shared channel of a message A (MsgA PUSCH), to avoid the segmentation of the RO resource set and the preamble set and ensure the system capacity. The access method provided by the present disclosure will be described in detail below with reference to specific embodiments. It should be understood that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.
It can be understood that, although not illustrated in
In the embodiments of the present disclosure, there are differences in MsgA PUSCH corresponding to different types of terminals. For example, different types of terminals correspond to different PO resources of MsgA. For example, the PO resources of MsgA corresponding to different types of terminals are the same, but the demodulation reference signal (DMRS) of MsgA PUSCH corresponding to different types of terminals are different. For example, the information carried in MsgA PUSCH corresponding to different types of terminals is different, and the information can indicate the type of terminal. Therefore, the network device can identify the type of the terminal according to the received MsgA PUSCH, to facilitate the subsequent targeted scheduling.
The specific types of different types of terminals are not limited in the embodiments of the present disclosure. For example, different types of terminals support different maximum terminal bandwidths and/or different minimum numbers of antennas, such as the aforementioned ordinary UE and the RedCap UE. In one embodiment, different types of terminals can also be terminals that are different in other embodiments, such as terminals with different service types, such as terminals with small data transmission (SDT) services and terminals with non-small data transmission types, or terminals that support random access network service slicing and terminals that do not support service slicing. Different types of terminals can also be a combination of the above-mentioned terminals with different bandwidths, numbers of antennas and service types. In the following description, the ordinary UE and the RedCap UE are taken as examples to explain. It can be understood that the method of the embodiment in the present disclosure is equally applicable if the ordinary UE and the RedCap UE are replaced by any different types of first terminals and second terminals.
For example, the PO resources of MsgA corresponding to the ordinary UE and the RedCap UE are different. For example, the PO resources of MsgA corresponding to the ordinary UE and the RedCap UE are the same, but the DMRSs of MsgA PUSCH corresponding to the ordinary UE and the RedCap UE are different. For example, the information carried in the MsgA PUSCH corresponding to the ordinary UE and the RedCap UE is different, and the information can indicate that the terminal is an the ordinary UE or RedCap UE.
The following will be further explained by specific embodiments.
In an implementation, the network device (such as a base station) configures different PO resources for the ordinary UE and the RedCap UE, and the ordinary UE and the RedCap UE have their own dedicated PO. For example, the time domain resources and/or frequency domain resources of the MsgA PUSCH of the ordinary UE and the RedCap UE are different. In addition, the RO resource set and the preamble set configured by the network device for the ordinary UE and the RedCap UE are shared. For example, the network device can broadcast and transmit the shared RO resource indication information, indicating the RO resource set and the preamble set shared by the ordinary UE and the RedCap UE, and also broadcast and transmit the ordinary UE-specific PO resource indication information and the RedCap UE-specific PO resource indication information, which are used for indicating the ordinary UE-specific PO resources and the RedCap UE-specific PO resources, respectively.
For example, as shown in
When transmitting the MsgA, the RedCap UE will transmit the preamble in the shared RO resource 41 and transmit the MsgA PUSCH in the exclusive PO resource 43 of the RedCap UE, and the preamble transmitted by the RedCap UE is selected from the shared preamble set. The ordinary UE will also transmit the preamble in the shared RO resource 41, but will transmit the MsgA PUSCH in the PO resource 42 exclusive to the ordinary UE. The preamble transmitted by the ordinary UE is selected from the shared preamble set.
Accordingly, for a network device that receives or blindly detects the MsgA, if the network device detects the MsgA PUSCH in the PO resource 43 dedicated to the RedCap UE, it can be determined that the RedCap UE initiated random access. If the network device detects the MsgA PUSCH in the PO resource 42 dedicated to the ordinary UE, it can be determined that the ordinary UE initiated the random access. Thus, the identification of the terminal type is realized.
For example, as shown in
For example, as shown in
Through the method of this embodiment, the network device can identify the RedCap UE and the ordinary UE at the initial access stage of the 2-step RACH, and the subsequent targeted scheduling can be carried out, and the resource utilization rate is improved. In addition, the RO resource set or the preamble set in this method does not need to be further divided, thus ensuring the system capacity.
In another embodiment, the PO resources configured by the network device for the ordinary UE and the RedCap UE are the same, that is, the time domain and frequency domain resources of the MsgA PUSCH corresponding to the ordinary UE and the RedCap UE are shared. However, the DMRSs of the MsgA PUSCH corresponding to the ordinary UE and the RedCap UE are different, that is, the ordinary UE and the RedCap UE have their own DMRS. For example, the network device can broadcast and transmit the shared PO resource indication information to indicate the PO time-frequency resources shared by the ordinary UE and the RedCap UE, and also broadcast and transmit the DMRS configuration information dedicated to the ordinary UE and the DMRS configuration information dedicated to the RedCap UE, which are used for indicating the DMRS of the ordinary UE and the DMRS dedicated to the RedCap UE, respectively. In addition, the RO resource set and the preamble set configured by the network device for the ordinary UE and the RedCap UE are still shared.
For example, as shown in
When transmitting the MsgA, the RedCap UE will transmit the shared preamble in the shared RO resource 71 and the MsgA PUSCH in the shared PO resource 72, but only the DMRS dedicated to the RedCap UE is used in the MsgA PUSCH. The ordinary UE will also transmit the shared preamble in the shared RO resource 71 and the MsgA PUSCH in the shared PO resource 72, but only the DMRS dedicated to the ordinary UE is used in the MsgA PUSCH.
The DMRSs of the MsgA PUSCH corresponding to the ordinary UE and the RedCap UE are different, which may mean that the ports of the DMRSs are different, the sequences of the DMRSs are different, or both the ports and the sequences of the DMRS are different.
For the DMRS ports, different DMRS ports are defined in NR, and different DMRS ports occupy different time-frequency resources and/or masks. A network device can determine the DMRS port used by UE according to the blind detection of DMRS of the MsgA PUSCH, and different types of UE can be distinguished.
For DMRS sequences, the DMRS of PUSCH in NR uses a pseudo-random sequence or a ZC (Zadoff-chu) sequence. Whether it is a pseudo-random sequence or a ZC sequence, a specific value of a sequence is determined by the initial phase C_init, which in turn is determined by the scrambling code. There are at most two scrambling ID of the DMRS of the MsgA PUSCH, namely msgA-ScramblingID0 (N_ID{circumflex over ( )}0) and msgA-ScramblingID1 (N_ID{circumflex over ( )}1). Therefore, the RedCap UE and the ordinary UE can use different scrambling ID, and the DMRS sequences of the RedCap UE and the ordinary UE are different. Accordingly, the network device can determine the DMRS sequence used by the UE according to the blind detection of the DMRS of the MsgA PUSCH, and different types of UE can be distinguished.
In an implementation, the scrambling code configuration information used by the RedCap UE is different from that used by the ordinary UE, for example, the scrambling code ID used by the RedCap UE is msgA-ScramblingID0-RedCap (N_(ID, RedCap){circumflex over ( )}0) and msgA-ScramblingID1-RedCap (N_(ID, RedCap){circumflex over ( )}1), which is different from that used by the ordinary UE.
In another implementation, the RedCap UE and the ordinary UE share scrambling code configuration information, but the RedCap UE and the ordinary UE only use one of msgA-ScramblingID0 (N_ID{circumflex over ( )}0) and msgA-ScramblingID1 (N_ID{circumflex over ( )}1), respectively. For example, the ordinary UE uses msgA-ScramblingID0 (N_ID{circumflex over ( )}0), while the RedCap UE uses msgA-ScramblingID1 (N_ID{circumflex over ( )}1).
Through the method of this embodiment, the network device can identify the RedCap UE and the ordinary UE at the initial access stage of the 2-step RACH, and the subsequent targeted scheduling can be carried out, and the resource utilization rate can be improved. In addition, in this method, the RO resource set or the preamble set does not need to be further divided, and the PO resource set also does not need to be further divided, thus ensuring the system capacity.
In yet another embodiment, the RO resource set, the preamble set, the PO resource set and the DMRS configured by the network device for the ordinary UE and the RedCap UE are all shared. However, the information carried in the MsgA PUSCH corresponding to the ordinary UE and the RedCap UE is different, and this information can indicate that the terminal is the ordinary UE or the RedCap UE, which can be called terminal type indication information, that is, the UE actively reports its type to the network device through the terminal type indication information carried by the MsgA PUSCH. Accordingly, after demodulating the MsgA PUSCH, the network device can determine the type of UE according to the terminal type indication information in the MsgA PUSCH.
In an implementation, the UE carries terminal type indication information through RRCSetupRequest in the MsgA PUSCH. The following is the definition of RRCSetupRequest in the prior art:
At present, the RRCSetupRequest includes RRCSetupRequest-IEs, while the RRCSetupRequest-IEs include ue-Identity, establishmentCause and an unused spare bit. Thus, there are three ways to carry the terminal type indication information in the RRCSetupRequest:
In another implementation, the UE carries the terminal type indication information through other parts besides the RRCSetupRequest in the MsgA PUSCH. For example, besides the RRCSetupRequest information, the MsgA PUSCH may also include a MAC Control Element (MAC CE), which includes at least 1 bit to indicate the type of the UE. In one embodiment, the MsgA PUSCH may include any other predefined format cell besides the RRCSetupRequest information, as long as the cell includes at least 1 bit to indicate the type of the UE.
Through the method provided by this embodiment, the network device can identify the RedCap UE and the ordinary UE at the initial access stage of the 2-step RACH, and the subsequent targeted scheduling can be carried out, and the resource utilization rate is improved. In addition, the RO resource set or the preamble set in this method does not need to be further divided, and the PO resource set does not need to be further divided, thus ensuring the system capacity.
